K0IN··on Faster Than Dijkstra?
I can only recommend (for all Germans here) this video from "dorfuchs":

https://youtu.be/3ge-AywiFxs?si=TbcRsBNkzGhpOxQ4&t=842

(timestamped=) He shows a derivation that at best, a sorting algorithm can do is O(n log(n)) for n real positive numbers.

K0IN··on OpenClaw security assessment [pdf]
Can someone give me context on why leaking the system prompt of a open source tool, I run on my machine is a problem?
K0IN··on Ask HN: Do you have any evidence that agentic coding works?
Same for typescript, by default you still got `any`, best case (for humans and LLM) is a strict linter that will give you feedback on what is wrong. But then (and I saw this a couple times with non-experienced devs), you or the AI has to know it. Write a strict linter config, use it, and as someone with not that much coding knowledge, you may be unfamiliar and thus not asking.
K0IN··on Ask HN: What non-LLM tools have meaningfully improved your dev productivity?
Docker starting test DBS, getting apps quickly to run without setting up all deps on my system.

Vscode.

Some people actually want to know and learn the things they use daily

K0IN··on Ask HN: What Are You Working On? (December 2025)
We currently don't have a website (sorry), but we are working on it!

And thanks for checking us out :)

K0IN··on Ask HN: What Are You Working On? (December 2025)
Flotte, a ssh access management solution for hobbyist and small to medium-sized businesses.

We aim to provide a fast JIT ssh cert attestation.

With focus on: * making on/offboard users fast * efficient workflows (no need to lookup passwords for logins or sudo) * mitigate private key leaks (especially in BYOD/BYOK environments) * Help admins manage server access fast

GitHub(WIP): https://github.com/flotte-sh

K0IN··on Why are your models so big? (2023)
Im always so surprised that embedding models we had for years like minlm (80mb) are so small, and I really wonder why not more on device searches use something like it.
K0IN··on Why Bcrypt Can Be Unsafe for Password Hashing?
I don't find this too concerning but libraries should document this and maybe even raise exceptions on data longer than 72 bytes, failing silently is the worst behaviour.
K0IN··on Dithering – Part 1
Hei, if someone wants to implement this, feel free to contribute this to my Phomemo M02 (a cheap < 15$) black and white thermal printer, web app.

K0IN··on Postman which I thought worked locally on my computer, is down
lately I really enjoyed using http files for sharing http example requests
K0IN··on Leaving serverless led to performance improvement and a simplified architecture
After building my first Serverless/Cloudflare worker app, this is why I migrated to Deno. Deno enables you to run the same codebase in deno (self-hosted/local) and in deno deploy (serverless platform from deno).

I wanted my app to be self-hostable as well, and Cloudflare worker is a hard ecosystem lock to their platform, which makes it undesirable (imo).

Here is a link to my reasoning from back then: https://github.com/K0IN/Notify/pull/77#issuecomment-16776070...

K0IN··on The phaseout of the mmap() file operation in Linux
thank you that was the first thing I had to check.
K0IN··on Why not Matrix (2023)
+1

I also want to add, I'm using beeper and there new app is fantastic but the old desktop app (and current webapp) are based on element.

Which for me had the worst experience possible, startup times way beyond 1 minute, the webapp just runs into a chrome oom when I keep it open for longer than 1 hour and also the user interface is super unresponsive and laggy.

I tried element (without beeper) and had the same issues, that's why I never got into matrix.

K0IN··on Show HN: Autumn – Open-source infra over Stripe
your example shows track in a tsx (I assume frontend) call, how does this work, why can't user just patch out the billing?
K0IN··on Ask HN: Alternatives to Cloudflare for DNS?
to add to this list

K0IN··on <Blink> and <Marquee> (2020)
in the German Mozilla docs there's was a warning: "this tag is one of the worst things you can do to your users, please don't use this" which they sadly removed.

here is the German version: https://x.com/K0IN1/status/1025459517499367425

K0IN··on Show HN: JSON_fast – 35% faster JSON parsing than serde_JSON
is this also faster when parsing no arrays or objects in serde? (if I'm not mistaken this lib can't do either)
K0IN··on Progressive JSON
For me this seems over complicated, or am i missing something?

Any benefits using this over jsonl + json patch?

K0IN··on Show HN: "Is This Tech Dead?" A snarky autopsy engine for your dead frameworks
my phone drops from 120 to 60 Hz when my battery gets low, for a brief moment I thought that my phone is getting empty just to return to Hackernews and noticing how bad the performance of this site is, for an webapp that just shows names and some numbers
K0IN··on Show HN: Letting LLMs Run a Debugger
Hei this is lovely,

i created a extension to help me debug a while back [0], and i thought of this (ai integration) for a long time, but did not have the time to tackle this.

Thank you so much for sharing!

I might need to add this approach to my extension as well!

K0IN··on Show HN: PomdAPI (Python) – Type safe API client with in-built Tag-Based caching
what is the upside of backend caching instead of using client side caching using for example cache headers?
K0IN··on TrailBase: Sub-millisecond open-source application base with Rust, SQLite and V8
what am I missing at the first benchmark? why is there no comparison to pocket base in golang (the language pocket base is written in, and is allowing extensions to be written in)?
K0IN··on The Missing Nvidia GPU Glossary
Is there a plain text / markdown / html version?
K0IN··on Lua Is So Underrated
I used Lua the first time in Garry's mod, and I had a absolute blast, was my first real programming language, I can vouch, it's easy to pick up :) I also must admit, the gmod lua extension (glua) was so much more enjoyable, that since then I keep my own lua version with patched ! for not and != as alternative for ~= (Luas way for not equal)
K0IN··on Show HN: GitHub-assistant – Natural language questions from your GitHub data
I really like the UI, great work, I have to dig through the code :) thanks for sharing!
K0IN··on Show HN: Find Domains Fast (Prices, SEO, AI and Alerts)
nice Idea but it shows prices for domains that are not possible, example I would like to have k0.in as a domain, but there are no 2 letter .in domains still it shows me 4 possible prices and buy options
K0IN··on Show HN: My weekend project to end Go/TypeScript boilerplate hell
Love it, gives me some trpc vibes (idk why) i would love to just create types for my existing endpoints (without rpc).
