Humans will typically learn after you have forced them to apologise for the same mistake for 20 times in a row.

AI won’t.

Fully agree. I tried to refactor parts of a large code base with Fable+ultracode and it just keeps accidentally merging distinct concepts and making up explanations/reasonings that the code base did not contain.

For example, the code base contains a physical controller. It’s closed loop in that it can react in realtime to changes. But it’s a slightly untypical implementation because this one can even look into the future through simulations. But Fable does not understand that. Instead, I need to remind it every 30 minutes that this is closed loop. It keeps wrongly claiming that the controller was open loop and then based upon that it will make up constraints that don’t actually exist.

Congratulations on the launch. The propeller demo looks good :) BTW, customising gears (which are then laser cut from sheet metal) is also a common request from untechnical people who need CAD help.

How do you differentiate from other open source AI CAD solutions? I’ve also had a good experience with Claude Code and CadQuery, which is a Python toolkit for generating CAD designs based on OpenCascade. I.e. what’s your moat?

And given that you’re YC funded .. what’s your plan for millions in MRR?

I’m asking because I would like to launch some useful open source tools myself (but for PIM, not CAD) and I just can’t figure out how to make open source sustainable, let alone profitable enough for hockey stick revenue growth. Any tips? Book recommendations?

The grab app shows un-skippable ads. And some taxis even have ads "based on your interests" playing on a TV in front of your seat. I found their "no marketing" ;) to be almost too much.

The thing that nobody talks about is how many EU citizens already are working on frontier models, just inside US companies. That’s why the prohibition was so crippling for Anthropic.

And, btw, the bang per buck that I got from OVH was better than EC2.

This is an interesting approach with integer programming and then using an explicit solver. It’s probably very slow, but you only have to run this once and it produces the mathematically perfect result.

In the past, I got good results with trying to reduce the variance in entropy in-between tokens, which you can implement very easily by starting with each single character as its own token and then doing a greedy merge of the most numerous outlier token pairs in a loop until you reach your desired token count. https://arxiv.org/abs/2206.12693

SEEKING WORK: Fractional CTO as Freelancer (Kiel, northern Germany, own company => 100% remote & easy to hire).

I built 3 products from idea to paying customers. So I can help your startup with architecture, implementation plans, and writing specs that you need to keep vibecoding sane. Depending on whether I get into YC (or most likely not, applied with just an idea), I might have free time coming up in the upcoming months.

Me, too. I love that they have tables with return and warranty percentages so you can see which products other people kept and which products only keep breaking.

The last 2 LAN parties we didn’t play anything that didn’t work extremely well on my AMD CPU + NVIDIA GPU Pop!OS Linux workstation.

And I didn’t expect: VR streaming works flawless, too. I just had to buy a WiFi 6 usb dongle.

"Maybe one day they will get around to unsuspending my account." is increasingly how support feels with all big cloud companies.

I got burned with an attitude like this: unexpectedly, people who had downloaded my open source tool for free started expecting support. Some of them sent pretty unfriendly emails.

This is going to save a lot of money ... until someone loots their vault and they go bankrupt. "Non-technical teams are now shipping production code" is the last thing you want to hear from your bank.

I think this is going to be wonderful. I'll have my offensive AI call their support AI and prompt-inject my way to a rebate tier that nobody knew existed and nobody can cancel it because all the remaining humans have been reduced to phone-to-screen input machinery.

Yes and that’s why I can charge premium rates for debugging. Most people cannot read a stack trace anymore.

Hi, I'm Hajo. 20+ years shipping production systems, 12+ as CTO. I'm a fractional CTO and I offer AI R&D, performance optimization, and due diligence as freelance consulting services. You might know me from:

ImageRights: sole architect, 10+ years in prod. Web crawling stack (5000+ concurrent tasks via Ansible), distributed C++ content-based image retrieval database scaling to billions of web images, all internal AI filters, plus workflow automation. Still running today.

Spatial Audio Designer: sole developer. 500+ channels real-time on 2013 hardware. NEON / AVX-vectorized DSP, plugins for VST / RTAS / AU / AAX, kernel drivers for virtual sound cards on Mac and Windows, ARM port for embedded and VR. Still in use by famous Hollywood studios.

And yesterday, I figured out how to make MSFS2024 run with multi-camera and instrument pop-outs in Proton 11. Understanding the root cause required tracing the full stack from inside the game, through vkd3d, Proton, the host Linux OS, down to the GPU driver.

Ideally, I'm looking for 5-10 days per month part-time projects. Plus I'd love to work on applied AI / robotics.

This is content marketing executed perfectly :) Reading it, I learned something new and interesting and they had an opportunity to show off one of their differentiators against the competition (low leakage flow due to tighter tolerances) and then at the end they casually mention the new product that has just opened for pre-orders.

Ugh. This is peak AI influencer. It’s a 21 page AI-generated presentation and an AI prompt for:

npm i -g @musistudio/claude-code-router

So it looks like the person who set up this GitHub repository didn’t even make the software that does all the actual work. They also never mention the original author in the README. But, of course, their AI prompt includes instructions to open their homepage, so this is effectively using the AI prompt for indirect advertisement. The HN submission title is also misleading. I didn’t see any maths in the repo.

EDIT: the underlying tool was discussed here on HN 9 months ago: https://news.ycombinator.com/item?id=44705958

AI beginners use Opus as a replacement for grep/sed.

Mediocre programmers use AI to write sed one-liners for them and then brag about AI productivity boosts.

And experts just use sed directly and then they wonder why everyone else is raving about AI.
