freitzzz··on Cherenkov Radiation - traveling faster than light
Not a science guy per se, is this blue the same blue in the radioactive accident in Goiânia’s?
freitzzz··on Show HN: Lightweight system monitor for Linux VPS written in Go
If I were to bet this is more a learning experience rather than trying to beat a product. Even better that this was done without AI (by the looks of it).

I’ve also done something similar in Go too, and several people used it, mostly because it’s easy to install/use and is lightweight.

freitzzz··on Cloudflare Email Service
If we're letting agents send e-mail, what's the point of reading e-mail? Surely I can have an agent to reply to e-mail that other agent has sent. Do we really want to create dead internet?
freitzzz··on Learn Prolog Now (2006)
A similar thing happened at my university in an Advanced Algorithms course. Students failed it so much, the university was forced to make the course easier to pass, by removing the minimum grade to pass.

I believe your case (and many other students) is that you couldn't abstract yourself from imperative programming (python) into logic programming (prolog).

freitzzz··on Show HN: Gametje – A casual online gaming platform
Cool idea, but you need to polish the UI. It looks completely generated by LLM (that's bad)
freitzzz··on Show HN: In a single HTML file, an app to encourage my children to invest
In my opinion this can't even be labeled as a single HTML file, because it loads external files to complete the app. But back to the question, a "plain html" file doesn't load any external resources and is usually semantically described.
freitzzz··on Show HN: In a single HTML file, an app to encourage my children to invest
Hi, sorry to be that guys, I just wanted to make some corrections on what you call your app a "plain html file". Your HTML file loads:

- react app - pwa manifest - tailwind css

This is not at all a "plain html" file.

freitzzz··on Steve Jobs and Cray-1 to be featured on 2026 American Innovations $1 coin
Gov doesn't care if it made devs happy or not, it cares if the products reached users and more importantly if it made them money
freitzzz··on What's a handy tool for creating/editing Lottie files, free/no watermark?
Tried it but it doesn't work on macOS arm64... :(
freitzzz··on I've always wanted to be an open-source maintainer- now I regret it
Hi, author here

The issue isn't socially interacting with any of the users, I wish that was the major pain point. The issue is having to handle e-mails, issues, feature requests, code-reviewing, continuous development, acquiring new users (otherwise project will stale) - all of this after a long day of work and balancing other important issues "non work related".

freitzzz··on Show HN: I made a 2D game engine in Dart
I would say that the best benefits are:

- Cross Compilation (even wasm and js) out of the box - Simple concurrency model, similar to NodeJS - Ability to use it on a popular cross platform framework (flutter) - Hot reload capibilities (has JIT and AOT mode) - Strong developer tool chain

All of these are built on top of a language that has a pretty syntax and supports many language paradigms.

The biggest con is the (weak) package ecosystem and community.

freitzzz··on Show HN: World's Radio – Listen to Radio Stations Worldwide
Hi! How does this differ from Radio Garden?
freitzzz··on Functional Programming in Go
Function operations are possible in Go like it’s possible in any language that define function in the syntax. But functional programming goes beyond functions, and Go was not designed to support it.

I’m a fan of Go and FP and would love to see someone bridge other FP aspects like monads, in a way that feels natural in Go.

freitzzz··on Firefox-Passwords-Decryptor: Extracts and decrypts passwords saved in Firefox
The additional features this tool brings (port enumeration, list usb devices, system info), makes me thing the tool was not designed for good/ethical reasons, but to ease the life of infostealers that are usually distributed via Discord.
freitzzz··on Using static websites for tiny archives
Really nice idea! As a data hoarder myself, I think I will follow this as way to remind myself of the things I truly should archive :)
freitzzz··on We need to build the GitHub of scientific data
Isn’t Dolt one of the initiatives for this?

Also not so long time ago, I saw a post on HN sharing a platform that does just this but for hospital data. can’t find tho

freitzzz··on Flappy Bird for Android, only C, under 100KB
You’d be surprised how heavy a language pack is!
freitzzz··on Flappy Bird for Android, only C, under 100KB
Most Android apps are huge because they bundle tons of assets just to accommodate the “initial experience of the user”. Also, using bloat libraries and frameworks (any shipped by Google), increase the apk size.

Nowadays Google offers a solution for this problem called app bundling. It’s especially good if you build a mono app that behaves differently in certain regions. Instead of delivering a raw apk, you deliver a region specific app bundle.

freitzzz··on Flappy Bird for Android, only C, under 100KB
Really cool! I just love seeing Android apps that weight less than a 1MB and run anywhere, even on your old HTC.

Congrats!

freitzzz··on Show HN: Server Uptime
Funny. Server Uptime but the host isn’t reachable
freitzzz··on How Bear does analytics with CSS
I attempted to do this back at the start of this year, but lost motivation building the web ui. My trick is not CSS but simply loading fake images with <img> tags:
