I spent this past weekend attending Handmade Seattle which is an independent, low level programming conference. It is usually held in Seattle but due to the ongoing COVID-19 pandemic, this year’s conference was held online.
First things first: wow. I was blown away.
I was really impressed at the quality of speakers and the content they brought to the table. It never ceases to amaze me how many smart folks are out there deep diving into complicated topics and sharing what they learn with the rest of us. Huge kudos as well to Abner Coimbre for organizing the event and the job he did facilitating as its host. Abner did a fantastic job of being professional and informed with the topics he discussed with the speakers while managing to keep it real in true indie fashion 😎.
Some of the talks were interviews between the speakers and the host, some were pre-recorded presentations or podcasts, but all ended with a Q&A with the speakers where all ticket holders were able to engage directly with the speakers using a private Matrix chat for which an invite was sent upon ticket purchase. It was really cool to see Matrix used like this in the wild, especially as it’s a project that my company recently invested millions into. I love the idea of this open, decentralized communication platform of the future. If you do too, we’re hiring engineers to help bring Matrix to Automattic 😊.
Without further ado – I have included a list of the speakers below with a brief take on some of their topics with links to where you can check out more of what some of these folks are doing.

Indie Game Dev – Developing Shader Expertise
This was my first exposure to Freya as I haven’t dipped many toes into the shader world but oh. my. god. This is the person that accidentally created the industry standard shader editor for the biggest game engine in 2014?
What a way to kick off this conference. Freya spoke heavily to the value in focusing on one thing and really digging down. In that, however, she emphasized a few points that I think is fantastic advice in general:
- Only learn the things you need to learn to do what you need to do.
- Don’t try to step into dozens of different topics, drill down and master one.
- Laser focus on one thing will result in getting more done faster.
I love this because it’s a super common problem in the tech world and for learning in general. You start working on a project, but there is so much to learn that it’s easy to get distracted or never progress because you start looking into the various adjacent technologies. You end up becoming okay at the basics in a dozen technologies but have no deep understanding required to truly innovate.
By the way, her YouTube channel is so good. Among other things, she has a dedicated series called “Math for Game Devs” which will make you a better game developer.
Polystream Senior Engineer – Modern CPU Optimizations: From the kernel to the cloud
This was so good. I know I probably sound like a broken record, but wow. Here was a AAA production solve for a performance bottleneck. The first obstacle had all of us laughing. Whoever had “Adobe Updater on the Server” on their systems bingo card, cash in that ticket!
Beyond that, Nuno orchestrated a deep dive into performance profiling. On this particular project, he and his team went so deep into the matrix that they ended up discovering a bug in the Microsoft kernel. What’s more, they were able to provide specific enough information to have that bug patched, fixing their application.
Yes, I couldn’t believe Microsoft actually patched a kernel bug either 😊.

Joey de Vries
Author – The History behind learnopengl.com
Really great talk about the history behind learnopengl.com and how Joey ended up starting what many to be the definitive resource behind learning what is basically the industry standard in graphics rendering.
Joey also has a new book: Learn OpenGL: Learn Modern OpenGL Graphics Programming in a Step-by-step Fashion which I will definitely be picking up!

Epic MegaGrants Recipient – Developing a Handmade Mindset for raylib
This guy. I have pretty much been Ramón’s self-proclaimed #1 fan for about a year now, and I knew that this talk was going to be amazing but holy moly.
How do you make an entrance into an indie programming conference? How about starting your presentation by compiling it from vanilla C source to web live using the software you wrote.
Do you think it stopped there? Um…..
I can fit on zero hands the amount of folks that thought guitar, cooking, and tree pruning would be the core tenants of a software conference talk.
Ramón expertly translated how he applied these three passions from his life to his approach to software development. I won’t be able to give this talk its due justice here, so I highly recommend checking out the recorded video.
Unity3D Engineer – You CAN Teach an Old Programmer New Paradigms!
Data Oriented Design. This is the content I purchased my ticket for. Elizabeth teaches DOD for a living and expertly broke down components of DOD using various worksheets throughout her talk:
This is my favorite software presentation slide ever:
Andrew Kelley, Ginger Bill, Joshua Huelsman
Compiler Writers – The Race to Replace C and C++
Excellent podcast between uber smart developers who work heavily with compilers and bring different perspectives to the table. Bill is the creator of the Odin Programming Language and converted many of his strong opinions into actions into his programming language. Josh is the creator of the Jiyu programming language and also worked on Johnathan Blow‘s upcoming Jai Language at Thekla. Andrew is the creator of the Zig Programming language. Abner keeps everything in order 😊.
Speakers: Day 2, November 15th 2020
Security Researcher – Linux Kernel Adventures: Reversing & Exploiting a Linux Driver
🤯. A very humbling talk about exploiting systems via kernel device drivers. Gal’s talk goes deep into the matrix, discussing and breaking down ioctl syscalls in depth.
This is one of those talks I’ll need to watch again….more than once 😅.
Kernel Developer – Parallelisation in the Linux Kernel
Outstanding presentation from a true legend in the space. Check out this rig that his friend built:
This is a computer with 6,144 cores. Yes, Linux supports this.
As a point of reference, Windows supports a max of 256 cores.
Linux Parallelism is state-of-the-artVegard Nossum
This talk perfectly covered the topics required to understand parallelism without going too deep into the rabbit hole on each branch (note: it is easy to do this). This is another talk I’m not capable of delivering justice to and highly recommend checking out Vegard’s work, white paper, and the talk itself.
White Paper – Ksplice: Automatic Rebootless Kernel Updates
White Paper – Compact NUMA-aware Locks
Hannah Gamiel & Eric A. Anderson
Myst VR Directors – Cyan, Inc.
Myst is upcoming VR game – but you already knew that. This interview was a cool chat between Abner and the directors of the project.
One recurring topic in the podcast was the obstacles encountered via a sudden switch to remote work during the global pandemic. In the private chat I told Hannah she could reach out if she wanted some insight on some best practices, as I know a few folks who set the gold standard for remote work 😏.
Other than that, it was just super cool getting a behind the scenes look at the folks @ Cyan and how they approached work on Myst and their transition to remote.

Microsoft Engineer; Cute Headers
Randy is a legend in the low level programming game space. If you’ve ever worked in this area you know about the Cute Header Libraries.
This talk highlighted how good these small and useful libraries actually are and referenced future improvements I wasn’t even aware of, like networking libraries supporting both TCP and UDP. He also laid out the roadmap for the project and what we can expect to be released within the next year or so. It’s always cool to know awesome projects are under active development working towards features everyone wants 😀.
System Software Engineer – A New Terminal Emulator
I was super looking forward to this as I basically live in the terminal, but it was postponed and totally understandably so. Abner has a working demo and is ready to present but was working so hard to host and keep everything organized that he chose to delay this a bit. Respect.

The How And Why Of Reinventing The Wheel / (Introduction To Dion)
It turns out the hype was worth the wait as Allen and Ryan revealed Dion to the world in a big way.
These guys weren’t kidding about reinventing the wheel. Imagine programming as you know it re imagined. When writing this I had a really hard time defining everything I was seeing, so I’ll let Ryan share his take:
Dion is our experiment at a new iteration of what it means to program. Our existing programming tools are hamstrung, and it shows; they are often dumber, slower, and more difficult to use than it feels like they should be. We (Dion Systems) have a theory about why that is, and we’re focused in on demonstrating what we think is the solution.
Dion aims to be an entire computing environment with one key tweak to the architecture of the programming systems we’re familiar with. Instead of storing code as text files, we store it as a more direct, structured representation that more closely maps to a traditional abstract syntax tree (which is a data structure that a compiler, for example, will use to store extracted semantic information from code).
Instead of storing code as text files, we store it as a more direct, structured representation that more closely maps to a traditional abstract syntax tree
This key tweak opens many doors. We now have the freedom to render code in different ways, achieve much smarter tools with much less effort, iterate on the user-interface and user-experience of the programmer, surface more sophisticated information about code, provide more insight for experts, improve the educational experience for beginners, and more, all with much less work.
We’re not done with our experiment, and our demo is just a first glimpse into the kind of future that rethinking the architecture of our programming environments can bring, but we’re really excited with what we’ve found so far, and wanted to share that vision with the Handmade community.

There were too many “omg” moments for me to count but a few include:
- All functions/procedures can be built by themselves.
- How you view the code is up to you. Inline braces, newline braces, no braces, it’s all on the table.
- Instant feedback on changes, errors, etc. The system knows not to build until something is fixed.
- Zooming in and out on code granularity. This is crazy to watch. You can look at all definitions and calls, or just the calls or definitions.
- Function arguments, variable declarations update their references instantly. By the way, this isn’t matching a string to do it. What? 🤯
I’m so excited to see where this project goes. There are a few hurdles the team will need to overcome (e.g. version control) – but there are more possibilities than there are obstacles…. you can count on that.
All of these talks were recorded and will be available soon at: https://www.handmade-seattle.com/
Between the interviews, there were “5 minute indie demos” which showcased some extremely interesting up-and-coming projects. Here were a couple that stood out to me:
This is one of the coolest cross-platform chat clients I’ve seen in a long time. It reminds me a lot of the old Trillian days. Remember Trillian? It would bring your AIM/ICQ/IRC convos into a single client.
Built in qt, it is a program designed to bring all of your various modern-day chat programs into one place in a localized client – without needing four 2GB electron apps murdering all of your CPU and RAM.
From the website, check out some of the features (emphasis mine):
- Not made from a web browser
- Multiple windows
- Multiple accounts
- Voice chat (Discord OK, Slack WIP)
- Graphical emoji and custom emoji
- Tab completion for user names and emoji
- Customizable fonts, colors, and sizes
- Custom bookmark lists for easily accessing only the channels you actually use
- Variable DPI and multi-monitor support
- Low CPU and memory usage
- Zero GPU usage
- No tracking or analytics
- No installer or forced updates
Here are some screenshots of the software:
I’m already tooling around with this, and really excited to see how this project evolves!
A really cool tool that compiles, runs, and debugs real time as you write code 😲. Is there more to say? Check it out below:
Syzygy is a crazy cool puzzle game which uses topology deformations as a game mechanic. I haven’t seen something like this before.
Get it here on Steam. Releasing 20 November 2020 (this Friday!)
