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?

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.

Map problems to slot machines, guess enough slots and you're indistinguishable from GI.

Hah, indeed, the story could have happened yesterday. Except maybe thinkpad prices in europe have normalized a bit ;)

What I didn't write is that my feelings towards the USA were 95% positive back then. A bit less after the chase and the Bronx visit, but still. Obama made everything feel hopeful. The current situation is just depressing.

Oh this brings back memories. Back in 2007 my dad needed a new Thinkpad which was like 2.5k EUR in NL vs 1k USD in the USA. He also wanted to push his kids to do something adventurous.

So he bought me (19) and little brother (16) tickets to fly from Amsterdam to New York (2x350) and get a cheap hotel for 2 nights (2x100). All to get a Thinkpad W500(?).

We had a great time. Got chased by a wild homeless person on Staten Island who followed us onto the ferry and we were scared stiff. Also walked all over Manhattan. Went to the Bronx but got stared at a lot so quickly went back to the subway. I can still hear the iconic "Stand clear of the Closing Doors" in my head.

Too bad the America from those days is gone.

Any experience with their DNS? Asking for a friend ;) only problem I've seen so far is lack of DS record support.

Comper needs someone that can build revolutionary UIs and go where no man has gone before. We are hiring a software engineer and a genius designer (with ideally some engineering prowess). 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 5 people. Find the vacancies on our site and send us an email.

Ok funny anecdote: I once did a special assignment for the CEO of Mendix to build a convertor for MS Access apps to Mendix. So, yes, I can confirm that this is roughly true ;)

I wrote a short post about it on my blog: https://blog.waleson.com/2022/10/access2mendix.html

No, because the parent org is French.

I'm using OVH Cloud for a customer. There's a bit of uncertainty about the CLOUD Act. As OVH has a US subsidiary, they are still doing business in the US and I have seen claims that this makes also their EU offering susceptible to the CLOUD Act. Does anyone know more details?

Comper needs someone that can design revolutionary UIs and go where no man has gone before. I don't know exactly what to call this role, as it crosses several disciplines: Design, Engineering, new UIs. 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 4 people. Find the vacancy on our site and send us an email. Site is a bit outdated as it's not prio #1. Happy to chat.

I've created a programming language and game for (my) kids called Stacky Bird. You learn Stack Based programming with Flappy Bird. Inspired by my old HP calculators, the game 2048 and Flappy Bird. In levels you earn a new instruction and at the end you have a complete instruction set, and can solve complicated puzzles. With new instructions you can even go back and solve previous levels more elegantly.

It's not mobile friendly yet, but maybe that'll be a next weekend project. At least you can view a video of a level on mobile.

My kids are loving it.

This is awesome! I'm also working on something like real-time collaboration on codebases, but nothing as freehand as this, really inspiring!
