Super happy user here! It's an excellent piece of engineering.

We're running a fork that supports a "sidecar" server for running multiple integration tests against. So if any tests that need the server are included, it spawns the server, runs the integration tests, and then shuts it down. By re-using the same server we speed up our runs tremendously.

Love your games Zach! Hope my kids will take to them at some point.

I'm showing this page to my team and investors every couple of weeks. Visual, animated explanations are MUCH better than textual content for deeply grokking something. This is what we're trying to build for large software systems. I love the animations on this site so much, thank you for building them.

I've been thinking that there might not be new programming languages. The amount of code in the current popular ones will explode, so that's what all LLMs will be trained on.

Good luck coming up with a new language and getting enough content out there that LLMs will be fluent with it.

If true, I think that's a shame. There's plenty of innovation still to be done.

Yes and yes. Uber for 260 eur arrived within 5 minutes after booking.

I was at a conference in Frankfurt, traveling back to Amsterdam with my cofounder and got stuck in Oberhausen. We have an early flight tomorrow and there's no trains in NL due to a strike tomorrow morning, so we decided to take an uber home.

At first the delay was 30 minutes. Then 2 hours. After 1h30 with zero updates we decided to bail. Just checked and nothing is moving yet, so we made the right call.

Nope, unfortunately not right now. Thank you!

we do a very comprehensive scan in multiple dimensions: git blame history, llm passes over every file and a tree-sitter analysis for cognitive complexity. We bring our opinionated approach for tools (do you have linters, CI/CD, static typing, agent docs) and score each aspect. We also create your architecture diagrams with our secret agent sauce, and map technical debt on each level of the C4 hierarchy.

bespoke canvas (based on pixijs) + sync engine. We want to be fully on-prem capable.

After getting the top spot in What Are You Working On in Feb 2025 ( https://news.ycombinator.com/item?id=43157056 ) I started a company on that idea at https://getcomper.ai . After solo building for 11 months I found a co-founder, got an angel investment, then got some ex-Miro folk on board and we are now building the product at breakneck speed.

We're a collaborative canvas + context engine for all the code and docs in your company, with a zoomable UI + CLI , where you can collaborate with your co-workers and agents.

We map technical debt, agent readiness, code complexity, security scanning, bus factor and more, so you can easily see how all the software in your company runs.

One of the most complex things is our incremental git blame engine built on top of GitOxide, as our backend is fully built on Rust. Our frontend is built on PixiJS so you can explore at gaming speed with 60Hz refresh rates.

Recently we sponsored Rust Week in Europe and a hundred or so developers tried our mini-game which is GeoGuessr for code, and got rave reviews. Future is looking bright!

Ugh same. I had a 49g and a 49g+ in high school. The 49g broke down and the other got robbed when my student room got burgled a couple years later.

Learned a lot of RPN programming on those things!

I saw one in the wild a couple months back but had to say it didn't live up to my memories. Super slow and clunky interfaces compared to our modern touch screens.

My dad's GP didn't know about this, and despite my dad saying "it's fine, I'm taking creatine", sent him for a kidney check-up. Then they found an unrelated tumor on the ultrasound. Seems to be benign and hopefully all will be well. If so, creatine saved his life ;)

It is _very_ different. In the case of outsourcing, where companies offer decent local wages in developing countries, it can not be compared to slavery which is the perpetual ownership of a person.

Now with H1B sponsorship, where I've heard rumors of companies taking away passports of their workers, it is very much evil, but not slavery.

Ok this might be weird but I've moved everyone in my 4 person team to our team plan and costs seem to have sky rocketed compared to the individual plans. Where before most people spent 20-100 USD, now the total bill is more like 1k USD. I haven't gone into the details but it feels like I'm being scammed.

Just as a thought experiment, what would be worse for humanity. Global warming or global cooling by the same amount of degrees C?

I'm in western Europe and really hope the AMOC will not collapse.

From the title I was hoping for this being hacky on the server application side, like how it aborts and clears the memory for a running query.

Still an interesting read. Just wondering, why can't the TCP connection of the query not be used to send a cancellation request? Why does it have the be out of band?

Hmm, I've been sending receipts straight into Gemini 3 Flash and it handles them just fine. No need for this whole pipeline and definitely MUCH cheaper. Am I missing something?

Comper | Software Engineer #2 (Frontend focus) | €80-110k + equity | Utrecht, The Netherlands | ONSITE | https://comper.io

We make software landscapes understandable and explorable. Our canvas is zoom-to-code, and shows data on overlays from all of the git repos in your company. LLMs go through the codebase and extract the architecture.

We provide clarity when it's most needed: re-orgs, onboarding, explaining the tech stack at board meetings. Or just being stuck in your IDE and want to ask your team mate a question. We'd like to do to large org codebases what Figma did to design.

Comper needs someone that can build revolutionary UIs and go where no man has gone before. Our UI is the core of our product: a zoomable canvas that has all your code, documentation and diagrams on it. We have a long way ahead and need serious thinking to make sure we explain the software stack as simple as can be.

I'm the founder & CTO. We just raised a pre-seed and are now with 6 people. Find the vacancies on our site and send us an email.
