I use Canvas (the LMS) a LOT for the classes I teach and, since I'm a hobbyist programmer, I enjoy writing little tools/scripts to help me create html code "snippets" that I can post into the html editor of my Canvas pages (e.g., striped tables, FAQs, flashcard-like study cards, an interactive story creator, and more).

I've also written a plaintext to QTI quiz converter since creating quizzes on Canvas is so slow (I realize, of course, many other people have already made these... I just happen to like mine). It currently supports fill-in-the-blank, multiple choice, matching, true/false and word bank style questions. You can also generate a printable (DOCX) version of whatever quizzes you make.

Here's the site: https://www.hacksforeducators.com

All the tools are free, and there's no login required. So if you are a teacher that uses Canvas and think any of these tools could help you, check them out!

I've been making a Rust-based XML parser that can be used on its own, or as a drop-in replacement for libxml2 at the C ABI level. Basically, it's not only 2x faster than libxml2, but being written in Rust eliminates a lot of cybersecurity risk. Roughly 70% of CVEs come from memory-safety bugs, a whole class that Rust rules out at compile time.

This is very cool! I was just looking for such a project and ended up using quick-xml since it satisfied my use case (needed to stream certain matches from a big XML file), and I didn't see yours. I love that it is a drop in for libxml2, that must have been a challenging constraint.

I will seriously consider adopting it as long as it supports streaming matches (it seems like it does).

I'm working on a highly specialized isosurface extraction algorithm for 3D-printable surface-based lattices.

https://www.linkedin.com/posts/okaleniuk_isosurface-mesh-stl...

The lattice configuration comes from a conventional triangle mesh, so you can prepare it with any STL editor of your choice, and the lattice shape comes from a precalculated Fourier polynomial in barycentric coordinates.

Prototyping the melee combat system for my next game, Today I Will Destroy You. It's mostly inspired by Sekiro, Tunic, the Zelda games, and Death's Door.

At the beginning of this year I was fractional CTO at a small b2b startup and was surprised by how what I considered to be the basic requirements of a customer support platform was split across multiple tools and all priced per-user. This essentially forced a small team to limit who in the org had visibility into what was being communicated to customers.

I set out to solve that with https://stayupfront.com and now that the build is in a good place i’m finally having to bite the bullet and learn marketing. I’m also realising that all the advice to start with marketing first was probably good advice!

Been working on terminal API client that uses .http file as source-of-truth. It's more like API-as-a-code then similar tools like Postman, Bruno or Yaak. Supports gRPC, graphQL, websockets, SSE, local mocks, SSH/k8s etc.

I'm building a GDPR compliant, privacy first, AI self improvement app.

I've paired with a psychologist and HR director from one of the best universities in Germany to leverage the fact AI has embedded within every human experience, personality types, shortcomings in recorded history among all languages, and all cultures, and we are trying to extract that knowledge and leverage it so we can analyze what makes you tick (for example being an introvert or extrovert to recharge your social battery) in every aspect, motivation, procrastination etc.

Analyzing solidly your profile in a sense those standard 'form' 1-5 tests can not capture.

Once that's done, we give you recommended activities to improve your weak points (perhaps asserting yourself a bit more if you tend to shy away).

The core things we are trying to solve is:

human coaches are limited by their own worldview and bias, we hope AI who has more knowledge to other human experiences can help you more.

Anonymity, we are full GDPR compliant with audited log table if any user access your records, we hope humans feel more at ease without the fear of being judged.

Accessibility, a single mother drowning with responsibilities doesn't have time or resources to evolve spiritually, we hope the accessibility and price point of our app solves this and helps people who can't hire coaches have a more meaningful life.

Most of all I want to use my skills to improve human lives, I've been working very hard on it.

We are near a beta launch, where it will be free for beta users, if you are interested please email at: martin.sejas@exara.ai

Working on Pho [1] my own TUI for pull requests across multiple repositories. It aims to be direct replacement of Github web UI for 80% of the use cases. The number of PRs I have to review on a daily basis is still increasing, and I didn't really like using the web version. This is made exactly how i like it, keyboard driven and fast.
