Transflective LCDs are used nowadays (as opposed to just reflective), my Pebble has one and the Daylight Computer is another modern device with one.

They're great if monochrome IMO, but the color variants suffer with brightness as each subpixel can only reflect 1/3 of the light, which makes the backlight necessary in more situations.

New comment by weltensturm in "Ideas on modernizing the open-source desktop"

weltensturm — Thu, 24 Sep 2026 11:13:21 +0000

What I'm missing from DEs is a "home folder" per virtual desktop. I want to switch to an empty desktop, `cd` into my project folder, and have all commands scoped to that folder.

For example: - New terminal: CWD is set to folder - File search: scoped to this folder - Run commands from launcher: dir contents are suggested as arguments - Command history: scoped to this folder

I wrote dinu[1] a decade ago but integrating with Wayland compositors is a pain (no widely supported "what workspaces are there"), so I gave up a little.

The wax expands due to ambient (even uniform) temperature. It's a linear actuator, so warm -> expanded and cool -> retracted.

I assume it's because age verification is something the attention slop merchants can work with, and they'd rather lobby for that instead of letting their entire business model be uprooted.

I'm sure "child friendly content" is part of their calculations, and I'm sure they'll try to interpret the rules in a way that maximizes their profit.

New comment by weltensturm in "My Steam Machine is a 50ft HDMI cable"

weltensturm — Fri, 26 Jun 2026 09:31:07 +0000

I have a 20m fibre optic cable, these things are great. Thinner than a standard cable. They are unidirectional, but mine has a dedicated copper line for CEC. 4k 120hz is no problem.

I also have a Pulse Eight CEC adapter in the chain, but I had to swap its included HDMI cable for full bandwidth.

Since I've switched to Linux I haven't had a chance to set up the software side for CEC though, does anyone happen to have recommendations?

New comment by weltensturm in "Rust’s dependencies are starting to worry me"

weltensturm — Sat, 10 May 2025 11:11:14 +0000

Rust has a million ways to solve a specific problem, as it is not opinionated and gets you down to the lowest level if needed. On top of that there's a million ways to encode your types. Then there's a million ways to bind C libraries.

The solution space is basically infinite, and that's a good thing for a systems programming language. It's kind of amazing how far rust reaches into higher level stuff, and I think the way too easy to use package manager and lively crate ecosystem is a big part of that.

Sometimes I wish for a higher-level rust-like language though, opinionated as hell with garbage collector, generic functions without having to specify traits, and D's introspection.

weltensturm — Wed, 07 Feb 2024 23:21:53 +0000

> which is why your phone’s screen needs a higher resolution than your TV, and why a movie at the theater looks fine, even though it may only be 2K

They should have measured the angular screen area for those scenarios, because this is entirely backwards.

weltensturm — Tue, 09 Aug 2022 18:44:12 +0000

Why is it http.Error(w, ...) and not w.Write(http.Error(...))? The latter would be way more clear in showing that nothing magical happens and a return (if wanted) is still necessary (I don't write Go, so I don't know the conventions)

I meant the Ryzen CPU (is there a GPU with that name?), should have been more specific.

My GPU is a GTX 1080 and it was unenjoyable to me with that CPU, now I have a 12600KF and it runs pretty well.

The OP article shows quite well how CPU bound this game is.

New comment by weltensturm in "First Principles Thinking"

weltensturm — Thu, 10 Feb 2022 12:31:17 +0000

All things start from theory, just not the kind you think about. It seems you are referring to the academic style of theories, but in reality it is much closer to your mentioned trial and error - if you think about it, trial and error also requires guesses and theories to be viable, just that they don't come in written form, but rather from intuition. And I think intuition is the fundamental building block of first principles thinking or whatever they want to call it.

Heh, this sounds just like the global event system I made for my D window manager: https://github.com/weltensturm/flatman/blob/master/common/ev... (which has some extra jingles with method annotations and event filters for convenience)

It looks like they switched from .doc to .docx in January, I wonder if the old format was the attack vector

New comment by weltensturm in "Everything you need to know about pointers in C (2010)"

weltensturm — Tue, 15 Sep 2020 10:58:13 +0000

By C half-assedly trying to make "* " part of the name, just so you can use "* ptr" everywhere like it is an actual variable name, you get confusions such as this.

First "foo_ptr's type is int * ", but then "The pointer has a type, too, by the way. Its type is int.".

I also refuse to agree with "An int * * 's type is int * ". :)

But I guess "the type of `* ptr` is int, the type of `ptr` is int * " would be even more confusing.

New comment by weltensturm in "Show HN: JavaScript-free personal bio hosting"

weltensturm — Sat, 01 Aug 2020 12:04:33 +0000

How does "built-in privacy" hold up when the bios are basically public?

It looks like the generated links are just based on the person's name as well, so it would be pretty easy to find a lot of people fast. Letting the user generate UUID (or something) based URLs that are valid for a limited time only should be standard.

These things are very vendor specific and proprietary, I was more thinking about general purpose programming languages.
