I enjoyed working through the book Creating GUI Applications with wxPython by Michael Driscoll, learning various techniques for programming GUI applications in Python using wxPython.

This book is not intended to be a beginners' tutorial. The first chapter is titled "An Intro to wxPython," but it's very basic. I think anyone with a few simple wxPython apps under their belt would have no trouble with this book, but as a complete beginner to wxPython, I struggled a bit. Again, the book is not intended for complete beginners, so that's my fault.

Of the book's 14 chapters, 12 are dedicated to example applications, one per chapter. So these are not toy applications — some of them are small, but all are complete and useful as-is, and all of the code is provided. But the code isn't just dumped for you to try to figure out — it's presented in small sections, in a logical order, with an explanation of each part.

The first application is an image viewer that opens a dialog to let you pick an image file, then displays it. It's a good choice for a first example. The functionality is useful but not at all complicated, so you can focus on the boilerplate common to wxPython applications and how to put together a few widgets into a working application.

From there, the applications gradually get more involved, including a calculator, a database editor, a tarball creator, a tool to search for NASA images, and even an XML editor.

Some of the chapters introduce useful third-party wxPython add-ons, like ObjectListView which is much better than the built-in ListView.

The final chapter is about distributing your application using pyInstaller. Including this was a good decision. As a Python developer I'm happy to pipx install application, but if you're building applications with wxPython, your target users are quite likely not experienced Python developers, and a simple way to distribute and install your application is important if you want it to be used.

If you're going to build applications with wxPython, I recommend taking a look at this book and if possible, working through the examples. I'm sure you'll learn a lot. There are links to purchase digital or paper copies at the author's blog.

Disclosure: The author, Michael Driscoll, provided a digital copy of his book for review. However, the author was not involved in the writing of this review and all opinions are my own.

PyCon 2019 attracted 3,393 attendees, including a group of six Cakti. When we weren’t networking with attendees at our booth, we attended some fascinating presentations. Below are some of our favorites. You can watch these talks and more on the PyCon 2019 YouTube channel.

From Co-founder & CTO Colin Copeland:

One tutorial and one talk stood out as my favorites.

Data Science Best Practices with pandas

I attended four tutorials and this was the last one on Thursday. Each tutorial is hands-on and lasts about three hours. By far, this was my favorite, primarily due to the exercise-based format. Kevin Markham was well organized and a great teacher, most likely because he runs Data School, which I discovered is in Asheville! The tutorial centered around analyzing the TED Talks dataset from Kaggle. Kevin live-coded each lesson, demonstrating best practices for slicing and analyzing the dataset with Pandas. Then he turned it over to us, providing several possible exercises with increasing levels of difficulty, which utilized the tools he just taught. I found the in-person exercises valuable as they made us practice the techniques right then, and therefore, learn through experience. I overbooked myself with four tutorials and didn’t have enough time to practice what I learned in all of them, so I felt like I got the most out of Kevin’s format, and I look forward to future tutorials with him. The full video of the tutorial is below, or you can view a condensed version.

Plan your next eclipse viewing with Jupyter and geopandas

This was the first talk I attended. I was excited to learn about using maps in Jupyter Notebooks, as I hadn’t had the chance to do so yet. Christy Heaton’s talk was very accessible with an easy to follow hypothetical question of: In what cities will we be able to see upcoming solar eclipses? After starting with a brief intro on eclipses, spatial data, and coordinate systems, she walked through a Jupyter Notebook, demonstrating the ease of mapping data in a notebook with geopandas. Eventually piecing together cities, eclipse paths, and years to show which cities would be best for viewing the 2024 eclipse over the U.S. I learned a lot from this talk, especially how easy it is to use matplotlib to visualize DataFrames with geometries. It’s great to see how notebooks can be used to easily explore spatial data with Pandas and Geopandas.

From Technology Support Specialist Scott Morningstar:

There was one PyCon talk that rose to the top for me.

Building an Open Source Artificial Pancreas

Sarah Withee spoke from the heart on this topic. She described the OpenAPS (open artificial pancreas system) which was created from an open source project that also involved hardware. It combines glucose monitors and insulin pumps to automatically manage insulin levels for those with type 1 diabetes. It was a project that the medical device companies didn’t want to take on because they didn’t think it’d be profitable. So Sarah and others took the matter into their own hands. From the talk, I learned a lot about how the pumps work and interact with each other and I saw how life-changing it is. Sarah is an adopter of the device, and she spoke about how her blood sugar levels went from being all over the place to being much more stable. The project really speaks to the power of people and open source. Now, the medical device companies are finally trying to incorporate it into their devices.

From Contractor Sean Harrison:

My top 3 picks this year included the following:

Leveraging the type system to write secure applications

Shannon Zhu from Instagram provided an informative overview of how Instagram has used type hints with the Pyre library to improve the security of millions of lines of Python. Type hints are a new area for me. This talk convinced me that starting to use them would be beneficial — not for improving performance, because they aren’t (yet?) used for that, but for the sake of validating the software’s interface security, particularly in terms of ensuring that “taints” from user input are “cleaned” before they are used.

Put down the deep learning: When not to use neural networks and what to do instead

Rachael Tatman from Kaggle gave an excellent overview of the different techniques of data science and encouraged people not to use deep learning until they know they need it. Machine learning has been and still is all the rage, and there were a lot of data scientists at PyCon. But I was glad to see some of the more traditional statistical methods being promoted alongside the newer ones.

Strategies for testing async code

Async was half the buzz at PyCon this year (the other half was machine learning), but a lot of places aren’t using asyncio very much yet. That’s one of the reasons I really liked this talk — not only did Neil Chazin, from Agari, give an accessible intro/overview to async programming, but he helped answer one of the key questions, which is “How do I write tests for it?” Watch his talk for the answer:

Remember, you can watch more presentations from PyCon 2019 on YouTube. Comment below on your favorites!

Pictured: I traveled to Cleveland, OH, for PyCon 2019, where I got this shot of the city skyline.

This year I attended PyCon for the first time. It’s rather amazing that I haven’t been before, since I’ve been using Python professionally for over 15 years. PyCon 2019 was held in Cleveland from May 1–9. There was so much to take in, and there are so many good things to say about it. It was a fantastic experience. But rather than provide a “mission report: 2019” a la Winter Soldier, I thought I’d do something more useful — write a guide to PyCon from a newbie perspective. Here are six lessons I learned from my first PyCon.

1. Register Early

PyCon regularly sells out, and the organizers have stated no desire to increase the size of the show (about 3,400 participants). We’re not yet to WWDC levels (Apple’s developer conference that sells out moments after registration opens), but it’s a good idea to register for PyCon as early as possible.

I learned this the hard way. By the time I was ready to register in mid-April, the conference was already sold out. Fortunately, Caktus Group, as a sponsor, had an extra conference pass available, so I was able to go after all. Note to self: Next year, register in February.

2. Open a Space

One of the most attractive aspects of PyCon is the open spaces. It’s very simple: There are several rooms available throughout the conference. The organizers put out boards with a schedule for each full conference day, and some cards and pens. Anyone (anyone!) can write a session topic on a card and post it on the board for a particular time and room. Then if anyone else is interested in your topic, they show up.

This simple setup is really inspiring. I’ve been to a lot of conferences over the years, and I’m always impressed that thousands of people will travel hundreds or even thousands of miles (and, at PyCon this year, from 59 countries) to sit in conference rooms and … passively listen to other people talk. I’ve often thought at such events, I could do this at home. Why don’t we have more open conversations? At PyCon, we can! This was one of my favorite aspects of the conference.

I attended several interesting open spaces, and there were several others that I wish I could have attended. Of note are:

• Caktus’ own Scott Morningstar hosted a game called WINTERHORN. This live action game is a simulation in which you try to use a variety of bad techniques to disrupt people’s lives. If you win: Congratulations, you’ve done evil in the world! Then you go away and start seeing these techniques in use, and you’re wiser to the ways of the world. (You can read more about Scott and his passion for live action role play games.)

• Vince Salvinno from CodeRed hosted an open space on Wagtail CMS. It was a great opportunity to talk about how different people are using the CMS. There were also several people present who were new to or just exploring Wagtail, so we were able to answer their questions and help them get enthused about this excellent CMS framework.

• I went to the open space on Falcon Framework, a very fast lightweight API framework. Here, I was the new person exploring something for the first time. The team spent much of the session talking about the framework in general terms for newbies like me, as well as plans for the upcoming releases (async was a big topic). I was so impressed with both the team and the framework that I decided to join them during the sprints (more on that below).

I also dove right in and hosted an open space myself — “Making Wagtail Better for Developers.” At Caktus we use Wagtail to provide our customers with a great content editing experience. We have another post on why Caktus loves Wagtail. It really is an excellent CMS, but there are a few aspects that could be made better, especially when it comes to data migrations, importing and exporting content, and editing content with nested StreamFields. I wanted to talk about a few of those issues with other developers and compare notes. Apparently, others wanted to talk about these things, too, because they showed up!

We made Wagtail better. (photo by Colin Copeland)

We had a good conversation about Wagtail and its development, and I was inspired to help make Wagtail better for developers by contributing to the project (I plan to talk about my work on data migrations in an upcoming blog post).

That is one of the best outcomes from a conference like this: You come away inspired to do better work.

3. Try Some Talks

When most people go to conferences, they focus on the talks, and while talks and keynotes are a great source of inspiration and learning, you can wear yourself out trying to go to them all. PyCon had a packed schedule of talks and keynotes (upcoming blog posts will go over some of them). Instead of maxing yourself out on all the talks, my recommendation is to pick only two or three talks to attend each day. Pick ones that will expand your knowledge and help you to think about how to grow in the coming year. Many of the scheduled speakers make their slides and recordings freely available after the conference, so if you can’t get to a talk during PyCon, you can continue the conference later in the comfort of your own home.

4. Nurture Your Network

It’s all about the community, they say, and seasoned conference goers know that conferences are one of the best opportunities to “make new friends, and keep the old.” Frankly, I put a higher priority on relationship-building activities than going to talks, and PyCon has a plethora of these activities to help you nurture your network:

• Open Spaces: Good ones are engaging and relational. They aren’t just lectures.

• Breakfast and Lunch: Every table is large, and you can join any conversation. Don’t miss the opportunity to talk with someone new. Like I did ... sleeping late and missing breakfast. At least I always got to lunch and met new people there.

• Dinner: If you meet a new friend or an old one, you can have dinner together offsite. This is a greater time commitment than breakfast or lunch, and can lead to a much deeper relationship. This is especially important for those who work remotely, like me: Having a meal or drink together is just about the only thing we can’t do on Slack. Over a meal, you can get to know people so much better, and the good vibes carry over into a better working relationship. Pictured: A group of us from Caktus had dinner one night with a couple of folks from the Truth Initiative, with whom we’ve recently been working.

• Vendors / Sponsors / Exhibitors: Many of the exhibitors are developers, and all of them have periods of boredom during three days of exhibiting. If you see someone at a booth who is not talking to anyone, they are probably bored out of their wits and would welcome an opportunity to talk to you. Just walk up and say, “Hi! Can you tell me about [whatever it is that they are exhibiting ]?” It can lead to some of the best conversations you have. Also, free t-shirts. However, the Caktus sales team was not bored during the conference — whenever I went by, Tim Scales and Ian Huckabee (pictured) were always busy talking with someone.

• Job Fair: The job fair, which is open to the public, is another great opportunity to talk with company representatives. You’re less likely to find someone bored, but you’ll be able to pack a lot of conversations into a couple of hours. Even if you’re not looking for a new job, it’s interesting to see what opportunities are available, and see if there is a new skill set you want to work on. You might even find the perfect opportunity. Last year, I met Caktus at the PyCon job fair (I went to the fair but not the conference itself). This year, I talked with a lot of other companies and learned more about the lay of the land. My take: There’s good work available for Python engineers who understand DevOps, can build APIs, can support data scientists, and work well in a dynamic, collaborative environment. In fact, that sounds to me a lot like working with Caktus Group. They’re hiring, by the way.

• Sprints: Not only are you contributing to a project, but you are working alongside some really smart people whom you might have just met. (More on the sprints below.)

5. Eat Early

Speaking of meals, it’s imperative to arrive early to the meal line, because developers are a hungry lot, and there isn’t really extra. I learned this the hard way. One day, I was so busy sprinting and trying to get my tests working that I didn’t go to lunch until 45 minutes after the opening bell. At that point, all that was left was a large plate of potatoes. At least they were really good potatoes. Pictured: I was on time that day.

6. Sprint!

After the conference itself there are four days of sprints. These are like open spaces, but for coding. Anyone can host a sprint for their open-source project. You get a table in one of the open spaces rooms, and you code together for any length of time, up to four days. The conference organizers provide the space (with power and internet) and lunch (be quick or eat potatoes), and you provide the code. It’s a pretty sweet opportunity to get your feet wet with some new projects, or to work with your project team in person (a great opportunity when you all live in different places). It’s a great time to be with others, and despite the fact that a lot of joking and talking takes place around the table, a lot of serious coding also happens.

For my part, even though my work and family schedule didn’t allow me to stay for the entire sprint, I decided to stay through Monday (the first sprint day) and check out a couple of projects. Based on my interactions during the conference, I chose to sprint with Falcon Framework (top photo at right) for a few hours, and then switched to CodeRed CMS (bottom photo at right) for a couple of hours. I was a complete newbie on both projects, but both teams were super helpful in getting me onboard, and I was even able to commit some code to each project (see here and here) before driving home Monday evening. Sprinting with these teams was a wonderful experience for me.

Prepare for Pittsburgh

Cleveland was pretty cool. I’m already looking forward to being in Pittsburgh for PyCon 2020. I hope to see you there. Just be sure to register on time — details about the next PyCon should be released mid-summer; you can watch @PyCon on Twitter for updates.

It may be no surprise that there are gamers among our Caktus crew, but you may be surprised by the type of games that Cakti play. From the ancient art of Mahjong to the modern fun of Pokemon, our team members cover it all.

Mahjong Master & Crossword Champ Tim Scales

Tim’s grandmother taught him to play Mahjong when he was about 10 years old. She learned to play the Chinese tile-based game in the ‘50s while living in Singapore, and she continued playing after she moved back to England. As a result, it became a regular family past time. Tim enjoys the speed, complexity, and competitiveness of Mahjong. “It’s a hard game for beginners to pick up, so while I love bringing new people into the game, it’s also a pleasure to play at the breakneck speed of experienced players,” he said.

In addition to Mahjong, Tim’s grandmother also instilled in him a love for crossword puzzles. “When I went to visit her in England, we would complete the Daily Telegraph crossword every morning over breakfast. She lived to be over 100 and was sharp until the end. She swore that doing the crossword was her secret. I view it as an investment in my future mental sharpness,” said Tim, who’s now a daily New York Times crossword solver.

According to the NYT Crossword app, Tim has completed over 800 puzzles, not including the hundreds he previously did on paper! And there’s no stopping him now. He’s on a 15-month streak of solving the NYT crossword (almost) every day. Coincidentally, another Cakti, Karen Tracey created NYT crosswords that were published from 2003 - 2010. “I went into the archives and found a puzzle that Karen created, and it was hard! It took about twice my average time to complete it,” Tim said. (Go Karen!)

Live Action Storyteller Scott Morningstar

In 1977, Scott’s uncle gave him and his brother Jason the original Dungeons & Dragons boxed set, which kickstarted a lifelong interest in tabletop and role-playing games. Jason began designing these types of games when he was in high school, and Scott tested them, providing feedback and suggestions. Several of Scott’s favorite games are ones that his brother created. In 2005, Jason founded Bully Pulpit Games.

Thanks in large part to D&D, Scott is especially into live-action role-playing games (or LARP games), which involve improvisation, storytelling, and acting. It’s the perfect fit for Scott, who says he was a “theater geek”. He prefers the genre of American Freeform LARP, which can last anywhere from 90 minutes to 4 hours. These games involve freeform story and character development. Scott especially enjoys LARPS based on historical events, and true stories, or ones that involve complex scenarios like time travel. “A lot of people play a game to win, but we play for the best story,” Scott explained. “I like to tell a good story. If you watch us play, you’ll see that what we do is closer to improv theatre than gaming.”

For 20 years, Scott and his brother have been involved with a weekly gaming group, and they regularly test games that Jason creates. They’ve also tested games made by designers around the world. “My favorite part of it all is spending time with my brother. Gaming has kept us connected,” Scott said. It’s also an interest that Scott has passed down to his sons, who are also into gaming.

Scott enjoys sharing his gaming interest and bringing other players together. He and his brother founded LARP Shack, which attracts players from as far as Washington, D.C., and Philadelphia. Scott has hosted LARP Shack events at Caktus since August 2017, and the next one will be held on April 27 — details in this private Facebook group and on the Caktus event calendar. Scott also organizes Local Area Network (LAN) parties at Caktus. These parties are a blast from the past! Attendees bring their own computer, which they connect to form a LAN to play online games. It’s a bit like playing online games during the days of dial-up. Scott plans to host the next LAN party sometime this spring.

Video Game Enthusiast Kat Smith

Kat can’t recall a time when she didn’t have a gaming console (or two, or three, or more!). As a kid, she played Bubble Bobble on a classic Nintendo with her grandmother, and she often watched her brother play Final Fantasy X. Other consoles she had growing up included Super Nintendo, Sega Genesis, Nintendo 64, PlayStation2 and 3. Currently, Kat is more interested in PC gaming, but she still owns a PlayStation 4 Pro, Nintendo Switch, and a Wii U. Kat's cat (pictured) also enjoys watching the video games.

She used to play a lot of multiplayer online battle arena (MOBA) games, “but the older I get, the more I like relaxing games,” Kat said. Now she’s into world builder, simulation, and visually appealing games. She enjoys open-ended games, and a few of her favorite video games are the Witcher 3, Skyrim, Civilization V, and Banished. She’s also a regular Minecraft player, and has it for PC, phone, and console. “Every 6 months or so I play Minecraft, mostly to see what updates have been made to the game. It's a really relaxing game where you can do whatever you want. And it's very customizable!” Kat said.

Kat has also been active in the Pokemon Go community since July 2016, and she plays daily. She’s now at level 33 (out of 40)! She sometimes participates in raids with fellow Cakti Dmitriy Chukhin. The Civil Rights Mural located outside of the Caktus office is a Pokemon Gym so there's almost always an opportunity to find a Pikachu or a Magikarp on her way in and out of the office. On weekends, Kat enjoys walking around town with her fiance and their dog, checking the poke stops on their route. If Kat were a Pokemon, she said she’d be a Snorlax or a Slaking!

Pictured: The final rush is on! Staff quickly check materials for our PyCon booth.

PyCon 2019 is almost here, and we’re excited to continue to sponsor this premier Python event, which takes place in Cleveland, OH, from May 1 - 9. PyCon attracts attendees from around the world, and for the first time, the conference will include a track of Spanish talks.

Caktus at PyCon

Connecting with the Python community is one of our favorite parts of participating in PyCon. We love to catch up with people we’ve met before and see new faces, too! We’ll be in the Exhibit Hall at booth 645 on May 2 - 4, where we’ll have swag, games, and giveaways.

Some of you may remember our Ultimate Tic Tac Toe game from previous years. Only a few committed players were able to beat the AI opponent last year. This year, any (human) champions will earn a Caktus hoodie and be entered into a drawing to win a Google AIY Vision Kit and a Google AIY Voice Kit.

Must-See Talks & Events

PyCon consistently attracts top-notch speakers who present on a variety of informative topics. Our team is especially looking forward to the following:

• Releasing the World's Largest Python Site Every 7 Minutes by Shuhong Wong
• Engineering Ethics and Open Source Software by Hayley Denbraver
• A New Era in Python Governance by Shauna Gordon-McKeon
• Migrating Pinterest from Python2 to Python3 by Jordan Adler and Joe Gordon
• Assets in Django without losing your hair by Jacob Kaplan-Moss
• How to Think about Data Visualization by Jake VanderPlas

Check out the full schedule of talks. Some of these will likely appear in our follow-up PyCon Must-See Talks series, so if you can’t make it to the event, check back in June for our top picks.

Open Spaces: Beyond the scheduled talks, our Technology Support Specialist Scott Morningstar is looking forward to the Open Spaces sessions, which are self-organizing, meetup-like events. Scott plans to run a game of WINTERHORN during one of the open spaces times. The live-action game allows players to reflect on the government and opportunities for activism. “I’m not sure if playing WINTERHORN will make you a better developer, but it may make you a better citizen, or at least better informed about what is happening in the world,” Scott said. Read more about Scott's passion for games like WINTERHORN.

Arts Festival: This year, PyCon includes a mini arts festival called The Art of Python, which will “showcase novel art that helps us share our emotionally charged experiences of programming (particularly in Python).” With his background in STEAM education (STEM + the Arts), account executive Tim Scales is particularly excited about the arts festival, which will provide a creative complement to the technical presentations and lectures.

New clients regularly ask us if we build WordPress sites. When we dig deeper, we generally learn that they’re looking for a user-friendly content management system (CMS) that will allow them to effortlessly publish and curate their site content. As we’ve written about previously, WordPress can be a good fit for simple sites. However, the majority of our clients need a more robust technical solution with customizable content management tools. For the Python-driven web applications that we develop, we love to work with Wagtail.

What is Wagtail?

Wagtail is a Python-driven CMS built on the Django web framework. It has all the features you’d expect from a quality CMS:

• intuitive navigation and architecture
• user-friendly content editing tools
• painless image uploading and editing capabilities
• straightforward and rapid installation

What Makes Wagtail Different?

From the user’s perspective, Wagtail’s content editor is what sets it apart, and it’s why we really love it. Most content management systems use a single WYSIWYG (“what you see is what you get”) HTML editor for page content. While Wagtail includes a WYSIWYG editor — the RichTextField — it also has the Streamfield, which provides an interface that allows you to create and intermix custom content modules, each designed for a specific type of content.

What does that mean in practice? Rather than wrangling an image around text in the WYSIWYG editor and hoping it displays correctly across devices, you can drop an image into a separate, responsive module, which has a custom data model. In other words:

As a user, you don’t need to customize your content to the capabilities of your CMS. Instead, you customize your CMS to maximize your content.

Let’s Take a Look

Below is a screenshot of the WordPress editing dashboard, with the single HTML content area. You can edit and format text, add an image, and insert an HTML snippet — all the basics.

Now take a look at Wagtail. Each type of content has its own block — that’s Streamfield at work. The icons at the bottom display the developer-defined modules available, which in this case are Heading block, Paragraph block, Image block, Block quote, and Embed block. This list of modules can be extended to include a variety of custom content areas based on your specific website.

Using the blocks and modules, a web content editor can quickly add a paragraph of text, followed by an image, and then a blockquote to create a beautiful, complete web page. To demonstrate this better, we put together a short video of Streamfields in action.

You can also learn more about Streamfields and other features on the Wagtail website.

Powered by Django

At its core, Wagtail is a Django app, meaning that it seamlessly integrates with other Django and Python applications. This allows near-endless flexibility to extend your project with added functionality. For example, if your application includes complex Python-based data analysis on the backend but you want to easily display output to site visitors, Wagtail is the ideal choice for content management.

The Bottom Line

Wagtail provides content management features that go above and beyond the current abilities of a WordPress site, plus the inherent customization and flexibility of a Django app. We love working with Wagtail because of the clear advantages it provides to our clients and content managers. We highly recommend the Wagtail CMS to all our clients.

Contact us to see if Wagtail would be a good fit for your upcoming project.

Pictured: Our library of reference books at Caktus cover topics including Django and Python, as well as project management and Agile methodologies.

At Caktus, we believe in continued learning (and teaching). It's important to read up on the latest industry trends and technologies to stay current in order to address our clients' challenges. We even maintain a library in our office for staff use, and we add references frequently. Our team enjoys sharing what they've learned by contributing to online resources, such as the Django Documentation and the Mozilla Developer Network Web Docs. Below is a list (in alphabetical order) of the books, blogs, and other documents that we’ve found to be the most accurate, helpful, and practical for Django development.

Django Documentation

Authors: Various

Recommended by Developer Dmitriy Chukhin

Overview: When Dmitriy first began learning about Django, he went through the official Django tutorial. Then, as a developer, he read through other pieces of documentation that are relevant to his work.

A Valuable Lesson: Dmitriy learned that detailed documentation makes working with a framework significantly easier than trying to figure it out on his own or from other developers’ posts about their errors. The documentation is readable, uses understandable language, and gives useful examples, making Django Documentation a lot friendlier than Dmitriy expected. It encouraged him to continue using it, since other core developers consider it important to make their software usable and well-documented. One thing that’s particularly helpful about the Django documentation is that pages now have a ‘version switcher’ in the bottom right corner of the screen, allowing readers to switch between the versions of Django for a specific feature. Since our projects at Caktus involve using a number of different versions of Django, it’s helpful to switch between the documentation to see when a feature was added, changed, or deprecated. Seeing the documentation on the Django Documentation site also encouraged Dmitriy to thoroughly document the code he writes for people who will work with it in the future.

Why You Should Read This: The Django tutorial is a great place to begin learning about using Django. The reference guide is best for those who are already using Django and need to look up details on how to use forms, views, URLs, and other parts of the Django API. The topic guides provide high-level explanations.

Django User’s Group

Authors: Various

Recommended by Lead Developer and Technical Director Karen Tracey

Overview: The Django User’s Group is a public Google Group that Karen found when she first started using Django in 2006 and ran into some trouble with database tables. She posted her challenges and questions on the Google Group and received a response the same day. She’s been using Django ever since — coincidence?

A Valuable Lesson: Django Users was Karen’s first introduction to the Django community and she learned a great deal from it. It was also her entry into becoming a regular contributing member of the community.

Why You Should Read This: If you have a Django puzzle that you can’t solve, searching the group and (if that fails to yield results) writing up and posting a question is a great way to get a solution. Karen also notes that sometimes it’s not even necessary to post since the act of writing the question in a way others can understand sometimes makes the answer clear! Reading various posts in the group is also a way to see the issues that trip up newcomers, and trying to solve questions by others also provides helpful learning opportunities.

High Performance Django

Authors: Peter Baumgartner & Yann Malet

Recommended by Developer Neil Ashton

Overview: High Performance Django, proclaims to “give you a repeatable blueprint for building and deploying fast, scalable Django sites.” Neil first learned about this book from friend and former coworker Jeff Bradberry, who pointed it out as a way to start pushing his Django development skills beyond a firm grasp of the basics.

A Valuable Lesson: Neil learned that making Django perform at scale means keeping the weight off Django itself. The book taught him about making effective use of the high-performance technologies that make up the rest of the stack to respond to browser requests as early and quickly as possible. It taught him that there’s more to building web apps with Django than just Django, and it opened the door to thinking and learning about many other features of the web app development landscape.

Why You Should Read This: This book is ideal for anyone who’s beginning a career in web app development. It’s especially helpful for those with a different background, whether it’s front-end development or something further afield like computational linguistics. It’s easy to lose sight of the forest for the trees as a new web developer, and this book manages to provide you with a feel for the big picture in a surprisingly small number of pages.

Mozilla Developer Network Web Docs

Authors: Various

Recommended by Developer Vinod Kurup

Overview: The Mozilla Developer Network (MDN) Web Docs are a popular resource when it comes to nearly any general web development topic. It’s authored by multiple contributors, and you can be an author, too. Vinod usually visits the site when he’s struggling with a piece of code, and the MDN pops up at the top of his web search results. Caktus especially loves the MDN because we were fortunate to work with Mozilla on the project that powers the MDN.

A Valuable Lesson: Vinod and his team used Vue.js on a recent project, and he learned a lot more about modern Javascript than he needed to know in the past. One specific topic that has confused him was Javascript Promises. Fortunately, the MDN has documentation on using promises and more detailed reference material about the Promise.then(). Those two pieces of documentation cleared up a lot of confusion for Vinod. He also likes how each page of reference documentation includes a browser compatibility section, which helps him to identify whether his code will work in browsers that our clients use.

Why You Should Read This: The MDN provides excellent documentation on every basic front-end technology including HTML, CSS, and Javascript, among others. Since Mozilla is at the forefront of helping to create the specifications for these tools, you can trust that the documentation is authoritative. It’s also constantly being worked on and updated, so you know you’re not getting documentation on a technology that has been deprecated. Finally, and most importantly, the documentation is GOOD! They cover the basic syntax, and always include common usage examples, so that it’s clear how to use the tool. In addition, there are many other gems including tutorials (both basic and advanced) on a wide variety of web development topics.

Towards 14,000 Write Transactions Per Second on my Laptop

Author: Peter Geoghegan

Recommended by CEO Tobias McNulty

Overview: Towards 14,000 write transactions per second on my laptop, is a relatively short blog post that provides an overview of two little-discussed Postgres settings: commit_delay and commit_siblings.

A Valuable Lesson: This post not only provides an overview of commit_delay and commit_siblings, but also an important change to the former that dramatically improved its effectiveness since the release of Postgres 9.3. For database servers that need to handle a lot of writes, the commit_delay setting (which is disabled by default, as of Postgres 11) gives you an efficient way to "group" writes to disk that helps increase overall throughput by sacrificing a small amount of latency. The setting has been instrumental to us at Caktus in optimizing Postgres clusters for a couple of client projects, yet Tobias rarely, if ever, sees it mentioned in more general talks and how-tos on optimizing Postgres.

Why You Should Read This: These settings will change nothing for read-heavy sites/apps (such as a CMS), but if you use Postgres in a write-heavy Django (or other) application, you should learn about and potentially configure these settings to improve the product.

Two Scoops of Django

Authors: Daniel Roy Greenfeld and Audrey Roy Greenfeld

Recommended by Developer Dan Poirier

Overview: Two Scoops of Django has several editions, and the latest is 1.11 (Dan read edition 1.8). The editions stand the test of time, and the authors go through nearly all facets of Django development. They share what has worked best for them and what to watch out for, so you don't have to learn it all the hard way. The authors’ tagline is, “Making Python and Django as fun as ice cream,” and who doesn’t love ice cream?

A Valuable Lesson: By reading the Django Documentation (referenced earlier in this post), you can learn what each setting does. Then in chapter 5 of Two Scoops, read about a battle-tested scheme for managing different settings and files across multiple environments, from local development to testing servers and production, while protecting your secrets (passwords, keys, etc). Similarly, chapter 19 covers what cases you should and shouldn't use the Django admin for, warns about using list_editable in multi-user environments and gives tips for securing the admin and customizing it.

Why You Should Read It: The great thing about the book is that the chapters stand alone. You can pick it up and read whatever chapter you need. Dan keeps the book handy at his desk, for nearly all his Django projects. The book is not only full of useful information, but almost every page also includes examples or diagrams.

Well Read

We have a small two-person Infrastructure Ops team here at Caktus (including myself) so I was excited to go to my first devopsdays Charlotte and be surrounded by Ops people. The event was held just outside of Charlotte, at the Red Ventures auditorium in Indian Land, South Carolina. About 200 people gathered there for two days of talks and open sessions. Devopsdays are held multiple times a year, in various locations around the world. Check out their schedule to see if there will be an event near you.

On Thursday afternoon, Quintessence Anx gave an awesome technical Ignite talk on Sensory Friendly Monitoring. She packed a whole lot of monitoring wisdom into 5 minutes and 20 slides, so I was then looking forward to what she had to say about diversity. She spoke on Unquantified Serendipity: Diversity in Development, and it ended up being my favorite talk.

Quintessence (pictured right) provided a lot of actionable information and answered many common concerns that people have with diversity. She told the story of how as a junior developer her mentors often told her how to solve problems, while they told her male peers how to find answers. She suggested that mentors give a “hand up, not a hand out” and stressed the importance of being introduced to a mentors network so that the mentee can start building their own networks. I thought that the talk had the right balance between urgency and applicability.

View her slides and a mind map of an earlier version of the talk.

The Friday Keynote was given by Sonja Gupta and Corey Quinn, and was titled Embarrassingly Large Numbers: Salary Negotiation for Humans. It focused on how to upgrade your income by getting a new job. This talk was informative and entertaining, including more f-bombs than all the other presentations combined. Some of the points they made were:

• interview for jobs you don’t plan to take
• interview at least once a quarter
• never take the first offer

They also recognized that negotiation is hard, but you are not rude if you ask for what you’re worth. I was looking forward to this keynote since I recently began following Corey’s newsletter, Last Week in AWS, where he has elevated snark to an art form.

I enjoyed the event, and I am looking forward to attending devopsdays Raleigh in the fall. The next devopsdays Charlotte will take place in 2020.

At Caktus, we strongly believe in professional development and continued learning. We encourage our talented team to stay up to date with industry trends and technologies. During 2018, Cakti attended a number of conferences around the country. Below is a list (in alphabetical order) of the ones we found the most helpful, practical, and interesting. We look forward to attending these conferences again, and if you get the chance, we highly recommend that you check them out as well.

All Things Open

Recommended by Account Executive Tim Scales

Next Conference Location: Raleigh

Next Conference Date: October 13 - 15, 2019

All Things Open is a celebration and exploration of open source technology and its impact. Topics range from nuts and bolts sessions on database design and OSS languages to higher-level explorations of current trends like machine learning with Python and practical blockchain applications.

The annual conference is heavily publicized in the open source community, of which Caktus is an active member. All Things Open attracts open source thought leaders from across industries, and it’s a valuable learning experience for both non-technical newbies and expert developers to gain insight into a constantly evolving field.

Tim particularly enjoyed the session by expert Jordan Kasper of the Defence Digital Service about his efforts to implement open source development at the US Department of Defense with the code.mil project. It was an enlightening look at the use of open source in the federal government, including the challenges and opportunities involved.

DjangoCon

Recommended by Developer David Ray

Next Conference Location: San Diego, California

Next Conference Date: September 22 - 27, 2019

DjangoCon is the preeminent conference for Django users, and as early proponents of Django, Caktus has sponsored the conference since 2009. We always enjoy the annual celebration of all things Django, featuring presentations and workshops from veteran Djangonauts and enthusiastic beginners.

David enjoyed Russell Keith-Magee’s informative and hilarious talk on navigating the complexities of time zones in computer programming. It’s rare for a conference talk to explore both the infinite complexity of a topic while also providing concrete tools to resolve the complexity as Russell did. Attending DjangoCon is a must for Django newbies and veterans alike. It’s an opportunity to sharpen your craft and explore the possibilities of our favorite framework in a fun, collaborative, and supportive environment.

Digital PM Summit

Recommended by Lead Project Manager Gannon Hubbard

Next Conference Location: Orlando

Next Conference Date: October 20 - 22, 2019

The Digital PM Summit is an annual gathering of project managers, which includes presentations, workshops, and breakout sessions focused on managing digital projects. The event is organized by the Bureau of Digital and was held in Memphis in 2018. Cakti attended and spoke at the conference in previous years; check out the highlights of Marketing Content Manager Elizabeth Michalka’s talk on investing in relationships from the 2016 conference.

The summit provides a unique opportunity for attendees to network and learn from each other. Indeed, the biggest draw for Gannon was the chance to be in the same room as so many other project managers. The project management (PM) role encompasses an array of activities — planning and defining scope, activity planning and sequencing, resource planning, time and cost estimating, and reporting progress, to name a few. There are professional books and months-long certificates to teach this knowledge, but nothing is better than being able to ask, “Hey, have you run into this before?” The ability to compare notes with PMs he doesn’t work with every day is invaluable, and the three most impactful sessions for Gannon were:

• Rachel Gertz’s talk “Static to Signal: A Lesson in Alignment”
• Meghan McInerney’s talk on “The Ride or Die PM”
• Lynn Winter’s talk “PM Burnout: The Struggle Is Real”

Each of these talks seemed to build on one another. Rachel Gertz set the stage with her keynote by pointing out that the project manager is the nexus of a project. The course of a project is determined by countless small adjustments, and the PM is the one who makes those adjustments. Nine times out of 10, when a project fails, it’s because of something the PM did or didn’t do.

Also a keynote, Meghan McInerney’s talk (pictured) identified the primary attributes of a PM who’s at the top of their game. They’re reliable, adaptable, and a strategic partner for their clients. When you hit this ideal, you’re the one asking stakeholders and team members hard questions about “Should we?” — and as the PM, you’re the only one who can be counted on to ask those questions. Lynn Winter’s lightning talk cautions against giving too much of yourself over to this, though. As she pointed out, the role is often made up of all the tasks that no one else wants to do, and there’s a good chance at least a few of those tasks will take a toll on you. You have to make space for yourself if you’re going to be effective.

Internet Summit

Recommended by Chief Business Development Officer Ian Huckabee

Next Conference Location: Raleigh

Next Conference Date: November 13 - 14, 2019

The Internet Summit is a marketing conference that attracts impressive speakers and provides opportunities to stay on top of digital marketing trends and technologies that can help drive growth and success. Internet Summit conferences are organized by Digital Summit and are also held in varies cities, in addition to Raleigh.

Digital marketing is constantly changing, so it’s important to stay current. At Internet Summit, Ian heard valuable information from dozens of the country’s top digital marketers who shared current trends and best practices for using real-time data to build intelligence and improve customer interaction and engagement. Keynote speakers included marketing guru, author, and former dot-com business exec Seth Godin and founder of The Onion Scott Dikkers.

These summits are key to staying on trend with how people want to be reached, and the execution strategies are, in most cases, proven. For instance, behavioral targeting tools have evolved to the point where ABM (account-based marketing) can be extremely effective when executed properly. Also meaningful for Ian was the talk Marketing Analytics: Get the Insights You Need Faster, by Matt Hertig. Ian walked away from the workshop with tangible advice on managing large volumes of data to provide meaningful insights and analysis more quickly.

JupyterDay in the Triangle

Recommended by Chief Technical Officer and Co-founder Colin Copeland

Next Conference Location: Chapel Hill

Next Conference Date: TBD

In 2018, Colin was excited to attended JupyterDay in the Triangle because it provided a chance to learn from the greater Python/Jupyter community, and it occurred around the corner in Chapel Hill. He especially enjoyed the following presentations:

Matthew McCormick’s talk on Interactive 3D and 2D Image Visualization for Jupyter, which demonstrated how notebooks can be used to explore very large datasets and scientific imaging data Joan Pharr’s talk on Learning in Jupyter focused on how her company uses Jupyter notebooks for SME Training and onboarding new members to their team

Colin’s favorite presentation was Have Yourself a Merry Little Notebook by Ginny Gezzo of IBM (pictured). She focused on using Python notebooks to solve https://adventofcode.com/ puzzles. The talk highlighted the value of notebooks as a tool for exploring and experimenting with problems that you don’t know how to solve. Researching solutions can easily lead in many directions, and it’s valuable to have a medium to record what you did and how you got there, and you can easily share your results with other team members.

Colin has worked with Jupyter notebooks, and sees great value in their utility. For example, Caktus used them on a project with Open Data Policing to inspect merging multiple sheets of an Excel workbook in Pandas (see the project in github).

Pycon

Recommended by Technology Support Specialist Scott Morningstar

Next Conference Location: Cleveland

Next Conference Date: May 1- 9, 2019

Cakti regularly attend and sponsor PyCon. It’s the largest annual gathering of Python users and developers. The next conference will take place in Cleveland, OH, in May 2019.

The event also includes an “unconference” that runs in parallel of the scheduled talks. Scott especially enjoyed these open sessions during the 2018 conference. Pycon dedicates space to open sessions every year. These are informal, community-driven meetings where anybody can post a topic, with a time and place to gather. The open sessions that Scott attended covered a wide range of topics from using Python to control CNC Milling machines to how reporters can use encryption to protect sources. He also enjoyed a session on Site Reliability Engineering (SRE), which included professionals from Intel, Google, and Facebook who spoke about how they managed infrastructure at scale.

• Stories of Security
• Love Your Bugs

TestBash

Recommended by Quality Assurance Analyst Gerald Carlton

Next Conference Location: Varies

Next Conference Date: Multiple

TestBash was so good in 2017, that Gerald decided to attend again in 2018. The conferences are organized nationally and internationally by the Ministry of Testing, and in 2018, Gerald attended the event in San Francisco. Gerald originally learned about the event on a QA Testing forum called The Club. Read about what he loved at the 2017 conference.

TestBash is a single-track conference providing a variety of talks that cover all areas of testing. Talks range from topics such as manual testing, automation, and machine learning, to less technical topics including work culture and quality.

One particularly interesting talk was given by Paul Grizzaffi, a Principal Automation Architect at Magenic. He declared automation development is like software development. Paul talked about how the same principles used when developing features for a website can also be used when building out the automation that tests said website. Just like code is written to build a website, code is also written to create the automated scripts that run to test the website, therefore there is a valid argument for treating automation as software development. The talk highlighted the point that sometimes automation is seen as an extra tool, but it’s actually something that we build to perform a task. So when we think about it, it’s not that different from the development process one would go through when developing a new website. Paul’s talk is available on The Dojo (with a free membership), and you can read more on his blog.

TestBash provides practical information that attendees can learn and take back to their teams to implement. Attendees not only learn from the speakers but also from each other by sharing their challenges and how they overcame them. It’s also a positive environment for networking and building friendships. Gerald met people at the conference who he’s stayed in touch with and who provide a lasting sounding board.

Worth Going Again

We recommend these conferences and look forward to attending them again because they provide such valuable learning and networking opportunities.

What conferences do you plan to attend this year? If you have any recommendations, please leave them in the comments below.

Pictured from left: Our musically inclined Cakti, Dane Summers, Dan Poirier, and Ian Huckabee.

The first installment of the secret lives of Cakti highlighted some colorful extracurriculars (including rescuing cats, running endurance events, and saving lives). This time, we’re taking a look at our team’s unexpected musical talents.

If you Google musicians and programming, you’ll find dozens of posts exploring the correlation between musical talent and programming expertise. Possible factors include musicians’ natural attention to detail, their trained balance between analysis and creativity, and their comfort with both solitary focus and close collaboration.

Cakti are no exception to this, and creative talent runs deep across our team. Here are a few of our musical colleagues.

Appalachian Picker Dane Summers

Contract programmer Dane is inspired by old-time Appalachian music as both a banjo player and flat foot clogger. After ten years of learning to play, he’s managed to accumulate four banjos, but his favorite (and the only currently-functional one) is a fretless that he plays in the traditional Round Peak style. He’s working up to singing while he plays, at which point we hope he'll do an in-office concert.

The Multi-Talented Dan Poirier

Our sharp developer Dan has multiple musical passions. As a singer, he lends his baritone to Voices, a distinguished community chorus in Chapel Hill. You can also hear him a couple of times a month on WCPE, the Classical Station, as an announcer for Weekend Classics. Rumor has it that he’s also a dab hand at the ukulele, though until he shows off his talents at the office we won’t know for sure.

Blues Guitarist Ian Huckabee

Holding the distinction as the only Caktus team member to jam with Harry Connick, Jr., our chief business development officer Ian has played blues guitar since he was 12 years old. He also started his professional career in the music business, managing the NYC recording studios for Sony Music Entertainment. His current musical challenge is mastering Stevie Ray Vaughan’s cover of Little Wing.

Waiting for the Band to Get Together

No word yet on whether Dan, Dane, and Ian are planning to start a Caktus band, but we’ll keep you posted. If they do, they’ll have more talent to draw from: our team also includes an opera singer, multiple guitarists, a fiddle player, and others.

Thank You for Reading Our Blog

We look forward to giving you more content in 2019, and we welcome any questions, suggestions, or feedback. Simply leave a comment below.

You may look at my job title (or picture) and think, “Oh, this is easy, he’s going to resolve to stand up at his desk more.” Well, you’re not wrong, that is one of my resolutions, but I have an even more important one. I, Jeremy Gibson, resolve to do less work in 2019. You’re probably thinking that it’s bold to admit this on my employer’s blog. Again, you’re not wrong, but I think I can convince them that the less work I do, the more clear and functional my code will become. My resolution has three components.

1) I will stop using os.path to do path manipulations and will only use pathlib.Path on any project that uses Python 3.4+

I acknowledge that pathlib is better than me at keeping operating system eccentricities in mind. It is also better at keeping my code DRYer and more readable. I will not fight that.

Let's take a look at an example that is very close to parity. First, a simple case using os.path and pathlib.

  # Opening a file the with os.path
  import os

  p = 'my_file.txt'

  if not os.path.exists(pn) : open(pn, 'a')

  with open(pn) as fh:
    # Manipulate

Next, pathlib.Path

  # Opening a file with Path

  from pathlib import Path

  p = Path("my_file.txt")

  if not p.exists() : p.touch()

  with p.open() as fh:
    # Manipulate

This seems like a minor improvement, if any at all, but hear me out. The pathlib version is more internally consistent. Pathlib sticks to its own idiom, whereas os.path must step outside of itself to accomplish path related tasks like file creation. While this might seem minor, not having to code switch to accomplish a task can be a big help for new developers and veterans, too.

Not convinced by the previous example? Here’s a more complex example of path work that you might typically run across during development — validating a set of files in one location and then moving them to another location, while making the code workable over different operating systems.

With os.path

  import os
  from shutil import move

  p_source = os.path.join(os.curdir(), "my", "source", "path")
  p_target = os.path.join("some", "target", "path")

  for root, dirs, files in os.walk(p_source):
    for f in files:
      if f.endswith(".tgz"):
        # Validate
        if valid:
          shutil.move(os.path.join(root,f), p_target)

With pathlib

  from pathlib import Path

  # pathlib translates path separators
  p_source = Path().cwd() / "my" / "source" / "path"
  p_target = Path("some/target/path")

  for pth in p_source.rglob("*.tgz"):
    # Validate
    if valid:
      p_target = p_target / pth.name
      pth.rename(p_target)

Note: with pathlib I don't have to worry about os.sep() Less work! More readable!

Also, as in the first example, all path manipulation and control is now contained within the library, so there is no need to pull in outside os functions or shutil modules. To me, this is more satisfying. When working with paths, it makes sense to work with one type of object that understands itself as a path, rather than different collections of functions nested in other modules.

Ultimately, for me, this is a more human way to think about the processes that I am manipulating. Thus making it easier and less work. Yaay!

2) I will start using f'' strings on Python 3.6+ projects.

I acknowledge that adding .format() is a waste of precious line characters (I'm looking at you PEP 8) and % notation is unreadable. The f'' string makes my code more elegant and easier to read. They also move closer to the other idioms used by python like r'' and b'' and the no longer necessary (if you are on Python3) u''. Yes, this is a small thing, but less work is the goal.

    for k, v in somedict.items():
        print("The key is {}\n The value is {}'.format(k, v))

vs.

    for k, v in somedict.items():
        print(f'The key is {k}\n The value is {v}')

Another advantage in readability and maintainability is that I don't have to keep track of parameter position as before with .format(k, v) if I later decide that I really want v before k.

3) I will work toward, as much as possible, writing my tests before I write my code.

I acknowledge that I am bad about jumping into a problem, trying to solve it before I fully understand the behavior I want to see (don't judge me, I know some of you do this, too). I hope, foolishly, that the behavior will reveal itself as I solve the various problems that crop up.

Writing your tests first may seem unintuitive, but hear me out. This is known as Test Driven Development. Rediscovered by Kent Beck in 2003, it is a programming methodology that seeks to tackle the problem of managing code complexity with our puny human brains.

The basic concept is simple: to understand how to build your program you must understand how it will fail. So, the first thing that you should do is write tests for the behaviors of your program. These tests will fail and that is good because now you (the programmer with the puny human brain) have a map for your code. As you make each test pass, you will quickly know if the code doesn’t play well with other parts of the code, causing the other tests to fail.

This idea is closely related to Acceptance Test Driven Development, which you may have also heard of, and is mentioned in this Caktus post.

It All Adds Up

Although these three parts of my resolution are not huge, together they will allow me to work less. Initially, as I write the code, and then in the future when I come back to code I wrote two sprints ago and is now a mystery to me.

So that's it, I'm working less next year, and that will make my code better.

‘Tis the season for shopping online, sending cute holiday e-cards, and emailing photos to grandparents. But during all this festive online activity, how much do you think about your computer security? For example, is your password different for every shopping and e-card site that you use? If not, it should be!

Given that Friday, November 30, is Computer Security Day, it’s a good time to consider whether your online holiday habits are putting you at risk of a data breach. And our top tip is to use a different password for every website and online account. You’ve probably heard this a hundred times already, but it’s the first line of defense that you have against attacks.

We all should take computer and internet security seriously. The biggest threat to ordinary users is password reuse, like having the same (or similar) username and password combination for Amazon, Facebook, and your health insurance website. This issue is frighteningly common — the resource Have I Been Pwned has collected 5.6 billion username and password pairs since 2013. Once attackers breach one of your online accounts, they then try the same username and password on sites across the internet, looking for another match.

If one password on one website is breached, then all your other accounts with the same password are vulnerable.

It’s worth reiterating: Don’t use the same password on more than one website. Otherwise, your accounts are an easy target for an attacker to gain valuable data like your credit card number and go on a holiday shopping spree that’ll give you a headache worse than any eggnog hangover you’ve ever had!

More Tips to Fend Off an Online Grinch

Here are a few more tips for password security, to help protect your personal information from attacks, scams, phishing, and other unsavory Grinch-like activity:

1. Create a strong password for every website and online account. A password manager like LastPass or 1Password can help you create unique passwords for every online account. Be sure to also choose a strong passphrase with 2-factor authentication for your password manager login, and then set it up to automatically generate passwords for you.

2. Choose 2-factor authentication. Many websites now offer some means of 2-factor authentication. It takes a few more minutes to set up, but it’s worth it. Do this on as many websites as possible to make your logins more secure.

3. Do not send personal or business-related passwords via email. It may be an easy means of communication, but email is not a secure method of communication.

Have Holly, Jolly Holidays

You have an online footprint consisting of various accounts, email providers, social media, and web browsing history. Essential personal info, like your health records, banking and credit records are online, too. All of this info is valuable and sellable to someone, and the tools they use to steal your data are cheap. All they need to do is get one credit card number and the payoff may be huge. Don’t let that credit card number be yours, otherwise, you won’t have a very jolly holiday.

Be vigilant, especially around the holidays, when there’s an increase in online commerce and communication, and therefore a greater chance that an attacker may succeed in getting the info they want from you.

DjangoCon 2018 attracted attendees from around the world, including myself and several other Cakti (check out our DjangoCon recap post). Having attended a number of DjangoCons in the past, I looked forward to reconnecting with old colleagues and friends within the community, learning new things about our favorite framework, and exploring San Diego.

While it was a privilege to attend DjangoCon in person, you can experience it remotely. Thanks to technology and the motivated organizers, you can view a lot of the talks online. For that, I am thankful to the DjangoCon organizers, sponsors, and staff that put in the time and energy to ensure that these talks are readily available for viewing on YouTube.

Learn How to Give Back to the Django Framework

While I listened to a lot of fascinating talks, there was one that stood out and was the most impactful to me. I also think it is relevant and important for the whole Django community. If you have not seen it, I encourage you to watch and rewatch Carlton Gibson’s “Your web framework needs you!". Carlton was named a Django Fellow in January of 2018 and provides a unique perspective on the state of Django as an open source software project, from the day-to-day management, to the (lack of) diversity amongst the primary contributors, to the ways that people can contribute at the code and documentation levels.

This talk resonated with me because I have worked with open source software my entire career. It has enabled me to bootstrap and build elegant solutions with minimal resources. Django and its ilk have afforded me opportunities to travel the globe and engage with amazing people. However, in over 15 years of experience, my contributions back to the software and communities that have served me well have been nominal in comparison to the benefits I have received. But I came away from the talk highly motivated to contribute more, and am eager to get that ball rolling.

Carlton says in his talk, “we have an opportunity to build the future of Django here.” He’s right, our web framework needs us, and via his talk you will discover how to get involved in the process, as well as what improvements are being made to simplify onboarding. I agree with Carlton, and believe it’s imperative to widen the net of contributors by creating multiple avenues for contributions that are easily accessible and well supported. Contributions are key to ensuring a sound future for the Django framework. Whether it’s improving documentation, increasing test coverage, fixing bugs, building new features, or some other aspect that piques your interest, be sure to do your part for your framework. The time that I am able to put toward contributing to open source software has always supplied an exponential return, so give it a try yourself!

Watch the talk to see how you can contribute to the Django framework.

That’s it, folks — another DjangoCon in the books! Caktus was thrilled to sponsor and attend this fantastic gathering of Djangonauts for the ninth year running. This year’s conference ran from October 14 - 19, in sunny San Diego. ☀️

Our talented Caktus contractor Erin Mullaney was a core member of this year’s DjangoCon organizing team, plus five more Cakti joined as participants: CTO Colin Copeland, technical manager Karen Tracey, sales engineer David Ray, CBDO Ian Huckabee, and myself, account exec Tim Scales.

What a Crowd!

At Caktus we love coding with Django, but what makes Django particularly special is the remarkable community behind it. From the inclusive code of conduct to the friendly smiles in the hallways, DjangoCon is a welcoming event and a great opportunity to meet and learn from amazing people. With over 300 Django experts and enthusiasts attending from all over the world, we loved catching up with old friends and making new ones.

#Djangocon 2018 in San Diego has been the most inclusive, breath of fresh air conference I've ever attended, with the most beautiful and diverse group of people. Way to go Team Djangocon, @FlipperPA !!! <3

What a Lineup!

DjangoCon is three full days of impressive and inspiring sessions from a diverse lineup of presenters. Between the five Cakti there, we managed to attend almost every one of the presentations.

We particularly enjoyed Anna Makarudze’s keynote address about her journey with coding, Russell Keith-Magee’s hilarious talk about tackling time zone complexity, and Tom Dyson’s interactive presentation about Django and Machine Learning. (Videos of the talks should be posted soon by DjangoCon.)

What a Game!

Thanks to the 30+ Djangonauts who joined us for the Caktus Mini Golf Outing on Tuesday, October 16! Seven teams putted their way through the challenging course at Belmont Park, talking Django and showing off their mini golf skills. We had fun meeting new friends and playing a round during the beautiful San Diego evening.

Mini golf was a blast! An ending worthy of the Masters: a 2-way tie until the very end when — drum roll — @GrahamDumpleton, last player on the course (pictured with caddies) won by a single stroke! Congrats! And thanks to everyone who came out. #DjangoCon pic.twitter.com/S79MoAr9zt

Thanks to all the organizers, volunteers, and fellow sponsors who made DjangoCon 2018 a big success. We look forward to seeing you again next year!

Pictured from left: Caktus team members Vinod Kurup, Karen Tracey, and David Ray.

The Caktus team includes expert developers, sharp project managers, and eagle-eyed QA analysts. However, you may not know that there’s more to them than meets the eye. Here’s a peek at how Cakti spend their off-hours.

Vinod Kurup, M.D.

By day Vinod is a mild-mannered developer, but at night he swaps his keyboard for a stethoscope and heads to the hospital. Vinod’s first career was in medicine, and prior to Caktus he worked many years as an MD. While he’s now turned his expertise to programming, he still works part-time as a hospitalist. Now that’s what I call a side hustle.

Karen Tracey, Cat Rescuer

When Karen isn’t busy as both lead developer and technical manager for Caktus, she works extensively with Alley Cats and Angels, a local cat rescue organization dedicated to improving the lives and reducing the population of homeless cats in the Triangle area. She regularly fosters cats and kittens, which is why you sometimes find feline friends hanging out in the Caktus office.

David Ray, Extreme Athlete

Software development and extreme physical endurance training don’t generally go together, but let me introduce you to developer/sales engineer David. When not building solutions for Caktus clients, David straps on a 50-pound pack and completes 24-hour rucking events. Needless to say, he’s one tough Caktus. (Would you believe he’s also a trained opera singer?)

Pictured: David Ray at a recent rucking event.

These are just a few of our illustrious colleagues! Our team also boasts folk musicians, theater artists, sailboat captains, Appalachian cloggers, martial artists, and more.

If you’re building or updating a website, you’re probably wondering about which content management system (CMS) to use. A CMS helps users — particularly non-technical users — to add pages and blog posts, embed videos and images, and incorporate other content into their site.

CMS options

You could go with something quick and do-it-yourself, like WordPress (read more about WordPress) or a drag-and-drop builder like Squarespace. If you need greater functionality, like user account management or asset tracking, or if you’re concerned about security and extensibility, you’ll need a more robust CMS. That means using a framework to build a complex website that can manage large volumes of data and content.

Wait, what’s a framework?

Put simply, a framework is a library of reusable code that is easily edited by a web developer to produce custom products more quickly than coding everything from scratch.

Django and Drupal are both frameworks with dedicated functionality for content management, but there is a key difference between them:

• Drupal combines aspects of a web application framework with aspects of a CMS
• Django separates the framework and the CMS

The separation that Django provides makes it easier for content managers to use the CMS because they don’t have to tinker with the technical aspects of the framework. A popular combination is Django and Wagtail, which is our favorite CMS.

I think I’ve heard of Drupal ...

Drupal is open source and built with PHP programming language. For some applications, its customizable templates and quick integrations make it a solid choice. It’s commonly used in higher education settings, among others.

However, Drupal’s predefined templates and plugins can also be its weakness: while they are useful for building a basic site, they are limiting if you want to scale the application. You’ll quickly run into challenges attempting to extend the basic functionality, including adding custom integrations and nonstandard data models.

Other criticisms include:

• Poor backwards compatibility, particularly for versions earlier than Drupal 7. In this case, updating a Drupal site requires developers to rewrite code for elements of the templates and modules to make them compatible with the newest version. Staying up-to-date is important for security reasons, which can become problematic if the updates are put off too long.
• Unit testing is difficult due to Drupal’s method of storing configurations in a database, making it difficult to test the effects of changes to sections of the code. Failing to do proper testing may allow errors to make it to the final version of the website.
• Another database-related challenge lies in how the site configuration is managed. If you’re trying to implement changes on a large website consisting of thousands of individual content items or users, none of the things that usually make this easier — like the ability to view line-by-line site configuration changes during code review — are possible.

What does the above mean for non-technical stakeholders? Development processes are slowed down significantly because developers have to pass massive database files back and forth with low visibility into the changes made by other team members. It also means there is an increased likelihood that errors will reach the public version of your website, creating even more work to fix them.

Caktus prefers Django

Django is used by complex, high-profile websites, including Instagram, Pinterest, and Eventbrite. It’s written in the powerful, open-source Python programming language, which was created specifically to speed up the process of web development. It’s fast, secure, scalable, and intended for use with database-driven web applications.

A huge benefit of Django is more control over customization, plus data can easily be converted. Since it’s built on Python, Django uses a paradigm called object-oriented programming, which makes it easier to manage and manipulate data, troubleshoot errors, and re-use code. It’s also easier for developers to see where changes have been made in the code, simplifying the process of updating the application after it goes live.

How to choose the right tool

Consider the following factors when choosing between Drupal and Django:

• Need for customization
• Internal capacity
• Planning for future updates

Need for customization: If your organization has specific, niche features or functionality that require custom development — for example, data types specific to a library, university, or scientific application — Django is the way to go. It requires more up-front development than template-driven Drupal but allows greater flexibility and customization. Drupal is a good choice if you’re happy to use templates to build your website and don’t need customization.

Internal capacity: Drupal’s steep learning curve means that it may take some time for content managers to get up to speed. In comparison, we’ve run training workshops that get content management teams up and running on Django-based Wagtail in only a day or two. Wagtail’s intuitive user interface makes it easier to manage regular content updates, and the level of customization afforded by Django means the user interface can be developed in a way that feels intuitive to users.

Planning for future updates: Future growth and development should be taken into account when planning a web project. The choices made during the initial project phase will impact the time, expense, and difficulty of future development. As mentioned, Drupal has backwards compatibility challenges, and therefore a web project envisioned as fast-paced and open to frequent updates will benefit from a custom Django solution.

Need a second opinion?

Don’t just take our word for it. Here’s what Brad Busenius at the University of Chicago says about their Django solution:

"[It impacts] the speed and ease at which we can create highly custom interfaces, page types, etc. Instead of trying to bend a general system like Drupal to fit our specific needs, we're able to easily build exactly what we want without any additional overhead. Also, since we're often understaffed, the fact that it's a developer-friendly system helps us a lot. Wagtail has been a very positive experience so far."

The bottom line

Deciding between Django and Drupal comes down to your specific needs and goals, and it’s worth considering the options. That said, based on our 10+ years of experience developing custom websites and web applications, we almost always recommend Django with Wagtail because it’s:

• Easier to update and maintain
• More straightforward for content managers to learn and use
• More efficient with large data sets and complex queries
• Less likely to let errors slip through the cracks

If you want to consider Django and whether it will suit your next project, we’d be happy to talk it through and share some advice. Get in touch with us.

Above: Caktus Account Manager Tim Scales gears up for DjangoCon.

We’re looking forward to taking part in the international gathering of Django enthusiasts at DjangoCon 2018, in San Diego, CA. We’ll be there from October 14 - 19, and we’re proud to attend as sponsors for the ninth year! As such, we’re hosting a mini golf event for attendees (details below).

This year’s speakers are impressive, thanks in part to Erin Mullaney, one of Caktus’ talented developers, who volunteered with DjangoCon’s Program Team. The three-person team, including Developer Jessica Deaton of Wilmington, NC, and Tim Allen, IT Director at The Wharton School, reviewed 257 speaker submissions. They ultimately chose the speakers with the help of a rating system that included community input.

“It was a lot of fun reading the submissions,” said Erin, who will also attend DjangoCon. “I’m really looking forward to seeing the talks this year, especially because I now have a better understanding of how much work goes into the selection process.”

Erin and the program team also created the talk schedule. The roster of speakers includes more women and underrepresented communities due to the DjangoCon diversity initiatives, which Erin is proud to support.

What we’re excited about

Erin said she’s excited about a new State of Django panel that will take place on Wednesday, October 17, which will cap off the conference portion of DjangoCon, before the sprints begin. It should be an informative wrap-up session.

Karen Tracey, our Lead Developer and Technical Manager, is looking forward to hearing “Herding Cats with Django: Technical and social tools to incentivize participation” by Sage Sharp. This talk seems relevant to the continued vibrancy of Django's own development, said Karen, since the core framework and various standard packages are developed with limited funding and rely tremendously on volunteer participation.

Our Account Manager Tim Scales is particularly excited about Tom Dyson’s talk, “Here Come The Robots,” which will explore how people are leveraging Django for machine learning solutions. This is an emerging area of interest for our clients, and one of particular interest to Caktus as we grow our areas of expertise.

Other talks we’re looking forward to include:

• “It's about time” by Dr. Russell Keith-Magee
• “’Normalize until it hurts; denormalize until it works’ in Django” by Flávio Juvenal
• “ORM: The Sequel” by Katie McLaughlin
• “Strategies for Zero Down Time, Frequent Deployments” by Nick Humrich
• “How to give a damn, and stand out” by Amber Wanner

Follow us on Twitter @CaktusGroup and #DjangoCon to stay tuned on the talks.

Golf anyone?

If you’re attending DjangoCon, come play a round of mini golf with us. Look for our insert in your conference tote bag. It includes is a free pass to a mini golf outing that we’re hosting at Tiki Town Adventure Golf on Tuesday, October 16, at 7:00 p.m. (please RSVP online). The first round of golf is on us! Whoever shoots the lowest score will win a $100 Amazon gift card.*

No worries if you’re not into mini golf! Instead, find a time to chat with us one-on-one during DjangoCon.

*In the event of a tie, the winner will be selected from a random drawing from the names of those with the lowest score. Caktus employees can play, but are not eligible for prizes.

On August 11, I attended the National Day of Civic Hacking hosted by Code for Durham. More than 30 attendees came to the event, hosted in the Caktus Group Tech Space, to collaborate on civic projects that focus on the needs of Durham residents.

National Day of Civic Hacking is a nationwide day of action that brings together civic leaders, local government officials, and community organizers who volunteer their skills to help their local community. Simone Sequeira, Senior Product Manager of GetCalFresh, came from Oakland to participate and present at our Durham event. Simone inspired us with a presentation of GetCalFresh, a project supported by Code for America, that streamlines the application process for food assistance in California. It started as just an idea, and turned into a product used statewide that’s supported by over a half dozen employees. Many Code for Durham projects also start as ideas, and the National Day of Civic Hacking provided an opportunity to turn those ideas into realities.

Pictured: Laura Biedeger, a Team Captain at Code for Durham and a co-organizer of the event, speaks to attendees. I'm standing to the left.

Durham Projects

We worked on a variety of projects in Durham, including the following:

One group of designers, programmers, and residents audited the Code for Durham website. The group approached the topic from a user-centered design perspective: they identified and defined user personas and wrote common scenarios of visitors to the site. By the end of the event they had documented the needs of the site and designed mockups for the new site.

Regular volunteers with Code for Durham have been working with the Durham Innovation Team to create an automated texting platform for the Drivers License Restoration Initiative, which aims to support a regular amnesty of driver’s license suspensions in partnership with the Durham District Attorney’s Office. During our event volunteers added a Spanish language track to the platform.

The “Are We Represented?” project focused on voter education: showing how the makeup of County Commissioner boards across the state compare to the population in their county. During the event I worked with Jason Jones, the Analytics and Innovation Manager of Greensboro, to deploy the project to the internet (and we succeeded!).

Pictured: The Are We Represented group reviews State Board of Elections data files.

Another group partnered with End Hunger in Durham, which provides a regularly updated list of food pantries and food producers (gardeners, farmers, grocery stores, bakeries) that regularly donate surplus food. The volunteers reviewed an iOS app they had developed to easily find a pantry, and discussed the development of an Android app.

Join Us Next Time!

The National Day of Civic Hacking gave volunteers a chance to get inspired about new project opportunities, to meet new volunteers, city employees, and to focus on a project for an extended period of time. The projects will continue at Code for Durham’s regularly hosted Meetup at the Caktus Group Tech Space. Volunteers are always welcome, so join us at the next Meetup!

If you ever struggled to implement a complicated development project, starting your next one with a discovery workshop will help. Discovery workshops save you time and money over the course of a project because we help you answer important questions in advance, ensuring that the final product lines up with your primary end goals. Our new guide, Shared Understanding: A Guide to Caktus Discovery Workshops, demonstrates the value of these workshops and why we’ve made them a core component of our client services.

Set Your Project Up for Success

Discovery workshops are vital in defining a project and are an ideal way to overcome the challenges that arise when multiple stakeholders have varying opinions and conflicting visions. By facilitating a discovery workshop, we create a shared understanding of the project and ultimately streamline the development process to ensure that our clients get the best value for their investment. Projects that begin with a discovery phase are more successful for these simple reasons:

• They cost less because we build the right thing first
• They’re done faster because we focus on the most valuable features first
• They have better results because user needs are prioritized from the start

Discovery workshops are part of our best practices for building sharp web apps the right way. We’ve proven that these workshops ensure that projects not only hit their objectives but that they do so on budget, reducing the likelihood of requiring additional work (or money) further down the line.

Get Our Guide

Shared Understanding: A Guide to Caktus Discovery Workshops explains what a Caktus discovery workshop is. It also:

• Demonstrates how to achieve a shared understanding among stakeholders
• Provides techniques to uncover discrepancies or areas lacking clarity in the project vision
• Explains how this knowledge translates into tangible benefits during the project estimation and development process

The guide is an introduction to the aspects of user-centered requirements gathering, which we find most useful at Caktus, and we hope you’ll take a moment to read the free guide:

On July 27 - 28, we ran our quarterly ShipIt Day here at Caktus. These 24-hour sprints, which we’ve organized since 2012, allow Cakti to explore new projects that expand or increase their skill sets. The event kicked off at 3:00 pm on Thursday and we reconvened at 3:00 pm on Friday to showcase our progress. The goal is to experiment, take risks, and try something new.

Here’s what we got up to this time:
