• AMA: I'm Eric Ries (The Lean Startup) & Author of New Bestseller Incorruptible

  «Please shut up and take my money». Jokes aside - can’t wait. Your book The Lean Startup helped me so much. I read it tens of times. It’s one of the reason I got great traction with mine startup https://playcode.io - AI App Builder on our custom cloud. Thank you Eric. - Source: Hacker News / about 1 month ago

• Ask HN: What are tools you have made for yourself since the advent of AI

  I built a complete clone if fly.io infrastructure: VMs, networks, etc. So I have my Vercel on bare metal machines to maintain full-stack apps on https://playcode.io. It took more than a year. - Source: Hacker News / about 1 month ago

• How's Linear so fast? A technical breakdown

  I completely rebuilt this sync engine + orm with relations, lazy loading etc, using Vue + Pinia in https://playcode.io. Google Linear’s videos, they explained in detail their architecture. Yes, I spent a few months. But it worth it. Every new field, model I need to add, it is so straightforward. I do love frameworks and foundations. They make live easier later by a lot. - Source: Hacker News / about 1 month ago

• Zerostack – A Unix-inspired coding agent written in pure Rust

  Don’t get me wrong, but 7K LoCs means it is still an early attempt to make a coding agent. It starts easy “ah it can edit and read files!”, but it requires a lot of extra effort to make properly for many edge cases, especially caching, price optimizations, etc. I’ve been implementing custom coding agent in https://playcode.io for 3 years already. Far beyond of 7K LoCs. So when you compare to “shitty slow” Claude... - Source: Hacker News / 2 months ago

• I Am Building a Cloud

  - k8s is insane peace of software. A right tool for a big problem. Not for your toys. Yes, it is crazy difficult to setup and manage. Then what? - cloud has bad and slow disk. BS. They have perfectly fast NVME. Something else? That’s it. Why I am so confident? I used to setup and manage kubernetes for 2 years. I have some experience. Do I use it more? Nope. Not a right tool for me. Ansible with some custom Linux... - Source: Hacker News / 3 months ago

• Changes in the system prompt between Claude Opus 4.6 and 4.7

  No, you underestimate how huge the malware problem right now. People try publish fake download landing pages for shell scripts or even Claude code on https://playcode.io every day. And the. They pay for google ads $$$ to be one the top 1 position. How Google ads allow this? They can’t verify every shell script. No I am not joking. Every time you install something, there is a risk you clicked a wrong page with the... - Source: Hacker News / 3 months ago

• Opus 4.7 to 4.6 Inflation is ~45%

  Opus 4.6 is the main model on https://playcode.io. Not a secret, the model is the best on the world. Yet it is crazy expensive and this 35% is huge for us. $10,000 becomes $13,500. Don’t forget, anthropic tokenizer also shows way more than other providers. We have experimented a lot with GLM 5.1. It is kinda close, but with downsides: no images, max 100K adequate context size and poor text writing. However, a... - Source: Hacker News / 3 months ago

• Claude Code is unusable for complex engineering tasks with the Feb updates

  I use it ultra extensively and it works absolutely fantastic. Sometimes I think: "people are right, it is worse now" and then realize it is mistake, poor context or poor prompt. Garbage in, garbage out. No, it works not worse, but better. I built entire AI website builder https://playcode.io using it, alone. 700K LOKs total. It also uses Opus. So believe me, I know how it works. Trick is simple: never ever expect... - Source: Hacker News / 3 months ago

  The best way to learn is to do it hands on. Only difference between doing it at school VS by yourself is that the school will do the leg work of gathering the learning materials for you.

• What is going on here? it appears that the array is being modified before the console.log above where the change are made?

  I've been doing some experiments on playcode.io trying to better understand how/when changes made to an array are made to a copy and when they affect the original. Something I cannot explain has happened. Here is the code:. Source: over 3 years ago

• Why isn’t this giving me the desirable output it is running it but I want it to tell me what’s in the brackets

  I am pretty sure it has to do with the IDE..usually you make yourself an index.html file, link your js file to it and then you can see the console output in your browser..i've tried it on playcode.io and it worked, but when I went back to try it on vscode - without any html file - it was the same as your code.
