severak_cz··on There is no official XScreenSaver GitHub repository
Is it known why this is happening?
severak_cz··on I built a programming language that LLMs can't use
PHP already has explode function.
severak_cz··on Recreational Programming
I can definitely see myself in there. I am mostly problem solver but each problem it's also place for explorign new ideas and/or developing some in-house library which gets reused over and over. Also I get easily distracted and thrown into some ADHD sidequest and end up with font tool which can also render maps.

severak_cz··on Ask HN: Fable hacked my piano, can I release the results?
> The PianoDisc versions are mp3s encoded with the right channel carrying MIDI to be played on the piano, and the left channel containing any accompanying music to be played through attached speakers (who doesn't want the harmonica on Piano Man?)

What a cursed format!

I don't understand what the designers were thinking of... 2000 Hz square wave on right channel? Seriously? Nobody would hear something suspicious and nobody would literally see it on spectrum analyzer. Maybe it's holdover from analog days and it was on casette tape before.

Also somebody reverse engineered it before - https://www.kinura.net/mid2pianocd/

So Fable probably just igested it from documentation of this software or some very obscure forum thread somewhere.

severak_cz··on .self: A new top-level domain designed to support self-hosting
Except that Klaus Mueller is definitely not unique name. Human names are not that unique.
severak_cz··on Microsoft hasn't had a coherent GUI strategy since Petzold
Delphi (or Free Pascal+Lazarus) and Visual Basic had this capability (to easily spin up GUI). It was called RAD.
severak_cz··on So where are all the AI apps?
My guess - these are not not on PyPI because of libraries. AI generating is good when you don't care about how your app works, when implementation details does not matter.

When you are developing library it's exact opposite - you really care about how it works and which interface it provides so you end up writing it mostly by hand.

severak_cz··on Microsoft's "fix" for Windows 11
Infecting with React can be easily explained by pathetic state of desktop application development environment.

severak_cz··on Drawvg Filter for FFmpeg
Well turtle graphics is not implemented in drawvg. But it should be easy to implement it.
severak_cz··on Kagi Translate now supports LinkedIn Speak as an output language
The old world is sunsetting, and the new paradigm is still in the incubation phase. We’re currently navigating a period of massive disruption—it’s officially the era of the monsters. Time to lean in, pivot, and embrace the chaos.

severak_cz··on Sizing chaos
Forget oil rig units. Clothes sizing is the true cursed unit system.
severak_cz··on Ask HN: When do we expose "Humans as Tools" so LLM agents can call us on demand?
It's probably already done but in some third world country and hidden behind NDAs.
severak_cz··on It's hard to build an oscillator
> There’s an old electronics joke that if you want to build an oscillator, you should try building an amplifier

This can be easily demonstrated using so called no-input technique[0] which basically means that you patch audio mixer output to it's input and it starts feedbacking and you can create some tones from this. Note that this needs to be done carefully.

severak_cz··on Show HN: I was in a boring meeting so I made an encyclopedia
Which AI did you used? It seems it's quite happy with inventing non-existing things [0] or adding nonsense to real things [1]. I like it for that - it's nice artistic demonstration about pitfalls of AI. Tlön, Uqbar, Orbis Tertius [3] in real life.

severak_cz··on A bug saved the company
This was the case when there was only MME. With something like a Voicemeter and Audacity you can have similar setup. I was able to have voice call on Messenger and simultanously stream it to the Facebook using OBS.

But it's very clunky, that's true.

severak_cz··on PHP 8.5 adds pipe operator
yes, for a long time - https://www.php.net/manual/en/class.iterator.php
severak_cz··on Welcome to url.town, population 465
It does not work for people who are using web interface of e-mail only. It would be nice to provide textual instructions (sent this subject to this e-mail) instead of mailto links only.
severak_cz··on Vector Tiles are deployed on OpenStreetMap.org
Yeah. MapTiler has much better styles in general.
severak_cz··on Vector Tiles are deployed on OpenStreetMap.org
Oh but that default style for Shortbread is so ugly! No contrast, missing details and lots of information lost.

Hopefully it's vector tiles and information are there (I checked in Maputik) so it's possible to create my own style (which I will definitely try).

severak_cz··on Hundred Rabbits – Low-tech living while sailing the world
Yes - this is definitely some kind of computer performance art or something like that.
severak_cz··on Show HN: Bedrock – An 8-bit computing system for running programs anywhere
It's a pity there is not some similar concept using more high level language (instead of assembly).

But I can see why as every interpreted language can be "fantasy console" on itself.

severak_cz··on Proposal: GUI-first, text-based mechanical CAD inspired by software engineering
It looks interesting and I see use cases for this but my tool is (and will be something little different) - it's more visual drawing tool (with exact dimensions) and human readable file format is more byproduct than not.
severak_cz··on Proposal: GUI-first, text-based mechanical CAD inspired by software engineering
I am already working on something similar yet much smaller - simple, easy to use 2D CAD for hobbyists, maps and geometric art. I have working prototype implemented in lua (Love2D) [0] and barebones text based file format[1].

Curently I am experimenting with drawing things in DeltaCAD (another easy to use CAD - unfortunately abandonware now), converting it to my format (via DXF export) and displaying it with javascript. I want to reimplement second version in javascript to be able to run it in browser and use better GUI components than those which I tried to implement myself.

severak_cz··on Show HN: I built an app to use a QR code as my doorbell
Feedback: Bad UX. After scanning your example code I got page which asked me to take photo and I get really confused because I thought you want me to scan QR code again but there is no way to switch to other camera of my phone.

Overall this feels too complicated. Unfriendly to people without smartphone or mobile internet. I understand this is DIY equivalent of camera doorbell, but I would definitely prefer some no-name chinese radio doorbell both as one ringing and maintaining it.

severak_cz··on Uxn
I am not surprised as Unxtal is very low level and with lot of constraints. It looks more like some tool of demoscene than a practical programming platform.
severak_cz··on Breaking Down OnlyFans' Economics
But there is some backslash against feminism in western world and there are communities where OF is (and always was) off the limits. Also I think that some parts of OF are at least debateable from feminist POV.
severak_cz··on Japan’s Temple-Builder Kongō Gumi, Has Survived Nearly 1,500 Years
I like how all Czech republic entries in this list are breweries (except for one hotel). There are some priorities of our people!
severak_cz··on Medieval
Old Android device with (pirated APK of) Caustic 3[0]. Or old Windows PC with Ultranos Dreamer[1] if you wanna go really medieval.

[0] Caustic 3 was removed from Google Play unfortunately, you need to download it from alternative sources

[1] see https://zahrada.svita.cz/en/ultranos-dreamer

severak_cz··on Medieval
Yeah, it was all 90s ROMplers and soundfounts. I can definitely record some dungeon synth bangers with my Kawai K1 (which is basically ROMpler, just samples are single cycle waveforms) and it sounds just right.
severak_cz··on Medieval
I found it really funny. It's obviously probably useless for actual medieval music[0] but I think it can find it's users in bardcore or dungeon synth circles.

You can definitely recreate this just by collecting appropriate VSTs and sample libraries, even probably by just loading some "medieval samples" to some groovebox.

But if I got this second hand on cheap price I would definitely make some fun with it even if it has somewhat cryptic labels.
