Its incredibly common to be thrown by this. Like many memes, the original incarnations were to be taken at face value, but then a layer of irony got applied, and the ironic/self-deprecating variant became the norm.

It varies. Reddit is/was the primary forum for a number of projects, and as each sub is community moderated, could be quite rich, even if the whole is “generally full of garbage”.

I get your point. Since a .tar.zst file can be handled natively by tar, using .tzst instead does make sense.

My shell is setup with a chdir hook to [[ -r. /.autoenv.zsh ]] && . ./.autoenv.zsh.

features

• mixed refresh rates
• (not GNOME) mixed VRR/nonVRR
• (not GNOME) Better mixed DPI?
• (not yet, experimental in gamescope) HDR support
• (not yet, experimental in KDE) persistence through compositor restart

It was the inability to add features like mixed refresh which caused Xorg devs to push for a new protocol. Otherwise it would be yet another series of janky patches to break assumptions made in a 40 year old protocol.

Other devs have been working on it. Valve’s contributions to wlroots, KDE, and gamescope can’t be understated.

gamma, 9 months ago (edited 9 months ago)

They are becoming more essential by the day. HDR and VRR is supported by just about every graphics card for the last 5 years, and displays which support both can be found for $200 or less. Valve had a reason to add HDR support to Gamescope/Steam Deck; it is a highly requested feature.

---

I will agree with you on one point: Xorg is not bad code. Xorg is an awesome project, and has developed and changed to the needs of users exceedingly well for decades. But X11 itself is tech debt. The first ten years of Wayland were spent paying that debt off (while simultaneously continuing Xorg development).

If the features aren’t what you need, then Wayland wasn’t built to support you today. But you might find yourself in 6 years looking at a gorgeous HDR display which works out-of-the-box on your favorite Linux distro thanks to Wayland.

gamma, 9 months ago (edited 9 months ago)

14 years later the need is slowly growing so the support is slowly growing

Yes! I agree wholeheartedly. Adoption has been slow because Wayland did not meet the needs of most people more than Xorg did. Cinnamon isn’t moving any time soon because the value-add isn’t enough for the average desktop user.

But…

build something that people need

People have needed HDR and VRR for years. HDR is essential for professionals in video and image editing. They needed Wayland years ago, and it was being built with them in mind, not just the average desktop user in 2012.

Not every feature is used by every user of that software. I used X-forwarding over SSH once, ever. It did not add any value to me. SSH forwarding adds no value to the average user either. But it is essential to someone.

gamma, 9 months ago

I was curious about what they’d say next. Their argument is “most users don’t need more than Xorg, so it’s ‘silly’ to expect investment in Wayland”.

I found some agreement in “as more people need Wayland features, investment will grow”, especially with the Valve and KDE/wlroots/gamescope. Also Automotive Grade Linux embracing libweston.

gamma, 9 months ago (edited 9 months ago)

Well, those requires D-Bus. The wlroots project decided early on to support non-dbus software stacks, so wlroots compositors expose Wayland protocol extensions which could either be used directly or wrapped by the xdg-desktop-portal-wlr daemon.*

---

*(Well… many wlroots devs argued that the ecosystem should have chosen WP extensions instead of dbus, but I think most relented when Pipewire entered the equation.)

Valve should get on this for gamescope, imagine Steam Deck doing a system update without closing your game.

Thought I’d check on the Linux source tree tar. zstd -19 vs lzma -9:

<span style="color:#323232;">❯ ls -lh
</span><span style="color:#323232;">total 1,6G
</span><span style="color:#323232;">-rw-r--r-- 1 pmo pmo 1,4G Sep 13 22:16 linux-6.6-rc1.tar
</span><span style="color:#323232;">-rw-r--r-- 1 pmo pmo 128M Sep 13 22:16 linux-6.6-rc1.tar.lzma
</span><span style="color:#323232;">-rw-r--r-- 1 pmo pmo 138M Sep 13 22:16 linux-6.6-rc1.tar.zst
</span>

About +8% compared to lzma. Decompression time though:

<span style="color:#323232;">zstd -d -k -T0 *.zst  0,68s user 0,46s system 162% cpu 0,700 total
</span><span style="color:#323232;">lzma -d -k -T0 *.lzma  4,75s user 0,51s system 99% cpu 5,274 total
</span>

Yeah, I’m going with zstd all the way.

Not all communities I want to follow made the transition. I’m still on Reddit for HFY, and some smaller game communities.

But Lemmy has replaced a sizable chunk of my Reddit usage, especially around more technical topics.

It requires a phone number to log in. That already kills any hope for anonymity. I use it to message family and close friends, of which the fact that I’m messaging them is not surprising.

My experience is still a good success rate there. Back in ~2015 my family got an USB WiFi card which needed an out-of-tree module, which the manufacturer had on Github, complete with DKMS instructions. It was upstreamed after about a year, though!

The only completely unsupported device I’ve had is my laptop’s fingerprint sensor.

It’s interesting, the results here are way different than the Code Golf & Coding Challenges Stack Exchange. I would never expect Haskell to be that low. But after looking at code.golf, I realize it’s because I/O on CG&CC is more relaxed. Most Haskell submissions are functions which return the solution.

Sidenote: I like the CG&CC method, it’s semi-competitive, semi-cooperative.

• all languages welcome
• almost all users post “Try it Online”/“Attempt This Online” links
• most users post explanations under their submissions
• often people will post solutions beginning with “port of user1234’s excellent Foolang answer” when there’s a clever shortcut someone finds
• or people will post their own solution with "here’s a solution which doesn’t use user1234’s algorithm"
• or people will add comments to answers with minor improvements

IMO It’s geared towards what is the best part about code golf: teaching people about algorithm design and language design.

An impossible dream of mine would be to check a list of devices with haptic touchpads, and disable tap-to-click on those.

Typically find “$HOME/docs”, but with a few caveats:

• In Zsh or Fish, the quotes are unnecessary: find $HOME/docs
• If I’m using anything potentially destructive: mv “${HOME:?}/bin” …
• Of course, if it’s followed by a valid identifier character, I’ll add braces: “${basename}_$num.txt”

gamma, 9 months ago

This isn’t true. Shellcheck doesn’t insist on braces unless it thinks you need them.

gamma, 9 months ago

This has never stuck with me, and I hadn’t thought about why until now. I have two reasons why I will always write ${x}_$y.z instead of ${x}_${y}.z:

• Syntax highlighting and shellcheck have always caught the cases I need to add braces to prevent $x_ being expanded as ${x_}.
• I write a lot of Zsh. In Zsh, braces are optional in way more cases. “$#array[3]” actually prints the length of the third item in array, rather than (Bash:) the number of positional parameters, then the string ‘array[3]’.

gamma, 9 months ago

in the OP

My reply is to a commenter who said they prefer “${HOME}/docs” over both options in the original image (“$HOME/docs” or “$HOME”/docs). Many people prefer to always include braces around the parameter name out of consistency, instead of only when they are required.

My comment explained why my habit is to only include braces when they are necessary.

Yep, I’m finding about half of my Reddit usage satisfied. I’ve got all the technical talk I want, but no gaming or writing communities.

I’m pretty sure both are possible in xkb. But you’ll have to learn how to get a custom xkb_keymap into your DE of choice. I only learned enough to do one mapping:

<span style="color:#323232;">xkb_keymap {
</span><span style="color:#323232;">	xkb_keycodes  { include "evdev+aliases(qwerty)" };
</span><span style="color:#323232;">	xkb_types     { include "complete" };
</span><span style="color:#323232;">	xkb_compat    { include "complete" };
</span><span style="color:#323232;">	xkb_symbols   {
</span><span style="color:#323232;">		include "pc+us+inet(evdev)"
</span><span style="color:#323232;">		key  {
</span><span style="color:#323232;">			type= "TWO_LEVEL",
</span><span style="color:#323232;">			symbols[Group1] = [  Multi_key,                Caps_Lock ],
</span><span style="color:#323232;">			actions[Group1] = [ NoAction(), LockMods(modifiers=Lock) ]
</span><span style="color:#323232;">		};
</span><span style="color:#323232;">		key  {[ Escape ]};
</span><span style="color:#323232;">	};
</span><span style="color:#323232;">	xkb_geometry  { include "pc(pc105)" };
</span><span style="color:#323232;">};
</span>

This remaps Capslock to Escape, Escape to Compose, and Shift+Escape to Capslock. Not what you want, but hopefully this will give you a starting point to playing/breaking xkb.

Another benefit of doing this with xkb: it’s now a separate codebase from X.org, and is used in every Wayland compositor I know of.

I learned Fish by helping someone else in a chat. There’s a lot of cool things, and I think it’s an excellent shell. Fish is an excellent choice for a shell.

Zsh is a much more featureful language (with globbing/subscript/PE flags, native floating point arithmetic, the whole man zshmodules), which doesn’t necessarily make it a better shell. But I like those features, and I find it to be a natural choice to write more complex programs which normally would be a code smell for Bash.

The plugin ecosystem for is much larger than Fish’s as well.
