New comment by monus in "My first patch to the Linux kernel"

> You may wonder whether I tried asking an LLM for help or not. Well, I did. In fact it was very helpful in some tasks like summarizing kernel logs [^13] and extracting the gist of them. But when it came to debugging based on all the clues that were available, it concluded that my code didn't have any bugs, and that the CPU hardware was faulty.

This matches my experience whenever I do an unconventional or deep work like the article mentions. The engineers comfortable with this type of work will multiply their worth.

> Along the way I have developed a programming philosophy I now apply to everything: the best software for an agent is whatever is best for a programmer.

Not a plug but really that’s exactly why we’re building sandboxes for agents with local laptop quality. Starting with remote xcode+sim sandboxes for iOS, high mem sandbox with Android Emulator on GPU accel for Android.

No machine allocation but composable sandboxes that make up a developer persona’s laptop.

New comment by monus in "The recurring dream of replacing developers"

monus — Sat, 17 Jan 2026 20:14:55 +0000

Agreed. I don’t know if it will create or eliminate jobs but this is certainly another level from what we’ve seen before.

Since last 2 months, calling LLMs even internet-level invention is underserving.

You can see the sentiment shift happening last months from all prominent experienced devs to.

Ask HN: Did Firecracker Win Completely?

monus — Sat, 27 Dec 2025 14:53:20 +0000

I’m seeing sandbox projects and companies almost everyday now with similar feature set and when I peek under the hood, it’s all Firecracker.

Is it really the best VM tech for 3rd party code with no alternatives? I know it’s good, but no competing project?

Well, we are serving latency sensitive remote control to via WebRTC which uses TLS over TURN so you get 443 HTTPS for the whole traffic.

No NAT, no UDP, just pure TURN traffic over Cloudflare TURN with TLS.

monus — Sun, 21 Dec 2025 15:11:45 +0000

We’ve recently had a disk failure in the primary and CloudNativePG promoted another to be primary but it wasn’t zero downtime. During transition, several queries failed. So something like pgBouncer together with transactional queries (no prepared statements) is still needed which has performance penalty.

We’re building the Browserbase for mobile - Android & iOS at agentic scale with no concurrency limits.

We run them on bare metal without VM brittleness, fully GPU-accelerated with WebRTC streaming using hardware encoder. As good as it gets and it’s amazed every single person who tried it.

Still behind waitlist, give me a heads up at hello@limrun.com to try it out.

New comment by monus in "Damn Small Linux"

monus — Mon, 08 Dec 2025 07:08:55 +0000

The problem with old computers isn’t that they’re slow but fail randomly so they don’t need “smaller” Linux, they need more resiliency that can work with random RAM erros, corrupt disks, absurd CPU instruction failures.

The size was a 90s problem.

monus — Sun, 09 Nov 2025 08:11:53 +0000

Agreed. Use LLM all you want to do the discovery and proof but do not use it to replace your voice. I literally can’t read, my brain just shuts off when I see LLM text.

The hard part is the content of isMalicious() function. The bots can crash but they’d be quick to restart anyway.

monus — Thu, 27 Feb 2025 22:22:09 +0000

> bringing HTTP/2 all the way to the Ruby app server is significantly complexifying your infrastructure for little benefit.

I think the author wrote it with encryption-is-a-must in the mind and after he corrected those parts, the article just ended up with these weird statements. What complexity is introduced apart from changing the serving library in your main file?

New comment by monus in "The "email is authentication" pattern"

monus — Sun, 08 Sep 2024 00:05:26 +0000

Well, yeah, “magic link” is a thing and one of the easiest form of authentication supported by many providers, like Supabase, Vercel and libraries like Next Auth.

Another great side effect is that your backend doesn’t have to store user passwords which means removal of a lot of compliance headaches.

Speed to open and general snappiness. Nothing comes close to Zed especially in larger codebases as most agree in the thread.

New comment by monus in "CRIU, a project to implement checkpoint/restore functionality for Linux"

monus — Sat, 22 Jun 2024 15:38:15 +0000

TCP connections are identified with source IP:port and target IP:port tuples. When a new pod is created, it gets a new IP so there is not much way to restore the TCP connections. So crik drops all TCP connections and lets the application handle the reconnection logic. There are some CNIs that can give a static IP to pod, but that’s rather unorthodox in k8s.

I built crik[1] to orchestrate CRIU operations inside a container running in Kubernetes so that you can migrate containers when spot node gets a shutdown signal. Presented it at KubeCon Paris 2024 [2] with a deep dive for those interested in the technical details.

We have implemented Terrajet (https://github.com/crossplane/terrajet) that generates CRDs that's completely compliant with Kubernetes Resource Model; references, label selectors, spec/status, no TF state blob saved anywhere.

Check it out!

‪That’s not an architecture diagram though, so it doesn’t represent the complexity at all.

I’m sure a troubleshooting map for bare linux server wouldn’t be less complicated than that.‬
