Am I to understand correctly that if you are running Gtk+ apps in the Gnome compositor, you get this working, but if you are running non-Gnome compositor with Gtk+ apps, it will not work? Or is it independent of the compositor?

flux ,

You should have backups. Preferably also snapshots. Then rm will feel less scary.

flux ,

Zooming and panning a pdf is arguably more comfortable with higher frame rate.

As opposed to buing a separate display for the computer?

I like to think this thing would be nice reading the news while having a breakfast or reading an e-book outside or at the bed, not near my computer. So it makes a lot of sense to build a tablet with this display technology.

Boox Tab Ultra

Looks pretty nice device! Even the camera makes a bit sense in the demo they give (though apparently in practice the scanning rarely works). And cheaper to boot as well. I might consider getting this one.

But is the display really better quality? Atleast the DPI is slightly higher at 219 on the Boox Tab Ultra vs 190 on the Daylight. And Boox weighs 70 grams less, and that’s the device some reviews call heavy (and some lightweight…).

These reviews mention the slow display speed:

So perhaps there is some room for improvement? That being said, some other reviews don’t mention it and one says it’s faster than typical e-ink display, though that doesn’t sound immediately purely praising.

In the end it probably comes to the software: how fast it is, it well it works, how nice it is to use. It seems both have customized the standard Android, so I suppose the difference is in which one has done it better and which one has better custom apps. Per the reviews Boox doesn’t fare too well in this aspect. Maybe someone will make a comparative review of the devices.

What a nice succinct explanation!

But also completely useless. Run0 ignores the suid bit for the same reason as 99% of command line apps do: it ignores because it isn’t relevant to its functionality.

flux ,

Would that kind of provision allow me to have my code removed from a git repository history, if that git repository is hosted by a company?

flux ,

I think the second point is the biggest for me: it’s almost like Canonical wanted to have a single dominant store for apps, as the ecosystem they are building supports only one. And, apparently, that one server is also closed?

So if you try to make an alternative source and give instructions to people how to configure their snap installation to use it (I found this information very hard to find for some reason…), your “store” probably won’t have the same packages Canonical’s has, so users won’t be able to find the packages and I imagine updates are also now broken?

Contrasting this with flatpak: you just install apps from wherever. Or from flathub. Or your own site. Doesn’t matter. No business incentive behind—built into the tools—to make everyone use flathub.org.

What's an elegant way of automatically backing up the contents of a large drive to multiple smaller drives that add up to the capacity of the large drive?

So I have a nearly full 4 TB hard drive in my server that I want to make an offline backup of. However, the only spare hard drives I have are a few 500 GB and 1 TB ones, so the entire contents will not fit all at once, but I do have enough total space for it. I also only have one USB hard drive dock so I can only plug in one...

flux ,

I just noticed lemmy.ml/u/[email protected] had proposed the same, but here’s the same but with more words ;).

I would propose you try to split the data you have manually into logically separate parts, so that you could logically fit 0.8 TB on one drive, 0.4 TB on another, and maybe sets of 0.2TB+0.2TB on a third one. Then you’d have a script that uses traditional backup approaches with modern backup apps to back up the particular data set for the disk you have attached to the system. This approach will allow you to access painlessly modern “infinite increments” backups where you persist older versions of data without doing full and incremental backups separately. You should then write a script to ensure no important data is forgotten to be backed up and that there are no overlapping backups (except for data you want to back up twice?).

For example, you could have a physical drive with sticker “photos and music” on it to back up your ~/Photos and ~/Music.

At some point some of those splits might become too large to fit into its allocated storage, which would be additional manual maintenance. Apply foresight to avoid these situations :).

If that kind of separation is not possible, then I guess tar+multi volume splitting is one option, as suggested elsewhere.

I suppose it explains why people have a bad attitude about Wayland when tools providing useful functionality are described as trojans.

X11 can (…mostly…) have great security by just providing a suitable X Security module to it. It just seems it wasn’t considered that big of an issue that anyone bothered. Nokia Maemo/Meego used to rock such a module.

flux ,

By that logic, is the compositor working any different than a trojan? Is there really a difference?

The Wayland compositor is always capturing all your keyboard and mouse as well. No permissions asked. Pretty sus.

I have 64GB RAM and my 64GB swap still gets filled to 60% over time.

It just happens so that apps end up touching some memory once that they never then use again. Better use some SSD for that instead of RAM.

flux ,

It’s two commands to grow the / fs on the fly:


<span style="color:#323232;">lvextend -L+10G /dev/mycomputer-vg/root
</span><span style="color:#323232;">resize2fs /dev/mycomputer-vg/root
</span>

So don’t worry about it. LVM is great :).

flux ,

I suppose they could implement smooth panning in high fps even if actual updates would be slower… though it might look funky.

flux ,

It doesn’t actually detect moved code, though, like git diff can? I gave it a shot and also there’s a couple issues open about it, e.g. github.com/Wilfred/difftastic/issues/520 .

Other than that, difftastic is quite nice.

I accidently rebooted during pacman update and now my system dosen't show option to boot into endeavour os. Systemd just shows option to boot into firmware interface please help!

I’ve lost everything and I don’t know how to get it back. How can I repair my system all I have is a usb with slax linux. I am freaking out because I had a lot of projects on their that I hadn’t pushed to github as well as my configs and rice. Is there any way to repair my system? Can I get a shell from systemd?

flux ,

I use etckeeper to autocommit changes in /etc as git just has better and faster tools to look at the changes of a fle, compared to backup tools.

It’s just so easy to do that there hardly is any point in not doing it.

flux ,

I suppose it’s the easiest way to try it out.

I wouldn’t use it long-term, because you don’t want Godot to update without you knowing, if there’s something that needs to be changed due to an update. I bet a few people noticed the update from 3.x to 4.x…

I’ve read it also doesn’t come with the C# support, so that’s one reason not to use Steam for it if you’re interested in testing that side.

flux ,

And how about the actual speeds they are used with? Another poster suggested the maintenance costs of traditional speeds skyrocket as speed increases, while maglev doesn’t really have a lot of stuff that wears down in the first place.

flux ,

Speed records aren’t usually representative of regular use top speeds, are they?

flux ,

I was under the impression cross-site cookies are a standard feature per the RFC, though? Or is Patreon using some kind of non-standard extension?

I rather enjoy Tilix. It can tile a single tab without tmux and it can also give special handling to links matched from regexps. I use it to go from Python stacktraces to correct line in Emacs with just a click. It can also do Quake-like terminal, which I use alot.

The project is looking for maintainers, though, so it’s possible at some point I need to start looking for alternatives…

flux ,

It still loses to HgBa2Ca2Cu3O8+6 with Tc = 133–138 K at normal air pressure, though. (I assume it’s normal air presure as the article doesn’t say the pressure for it, while it refers to some others as high-pressure ones.)

Maybe LK-99 still has other benefits, such as not using mercury.

Lemmy Defederation Sync (LDS) to keep your block list up to date (github.com)

Hi all, I’m a Lemmy FOSS app contributor that’s made a couple of tools for people starting small instances including Lemmy Community Seeder (LCS) for building content on new server’s All Feeds and Lemmy Post Purger (LPP) for clearing old posts on smaller instances....

flux ,

Admins can and do use email server block lists, though, so maybe that’s a great example.

I suppose you’re right–for now. But at some point Lemmy etc will grow large enough to make manual blocking infeasible. Just how much effort does it take to start a new instance even today?

In other words, if all the billionaires just ceased to exist, it would result in the humanity achieving the emission goals?

Thomas Gleixner aims for "decrapification" of Linux APIC code, longs for removing 32-bit code (lore.kernel.org)

Thomas Glexiner of Linutronix (now owned by Intel) has posted 58 patches for review into the Linux kernel, but they’re only the beginning! Most of the patches are just first steps at doing more major renovations into what he calls “decrapification”. He says:...

flux ,

I doubt there would be a measureable benefit: after all, the kernel is already compiled without 32-bit support, and the code related to it just doesnt exist in the resulting binary. I assume there could be some small exceptions, though, like choosing to do something in a certain way so that the same approach will also work for 32-bit, and opting for another approach would perform better in 64-bit. That’s just a guess, though.

It’s mostly about maintenance load.

Btw, with PAE the host can have more than 4 GB of memory, so the limit would only apply to individual processes. Still quite feasible to use that kind of system even in the modern day–even if the browser can sometimes become quite large… And then there are of course the numerous embedded applications.

flux ,

A patch contains more than the changes: it contains the commit message. In open source projects, and in particular in CVE fixes, the commit message can indeed be quite descriptive. It needs to be!

You’re still right, though. But I like to think professionals are able to verify the changes with the high-quality commit message—possibly in less time than investigating the issue themselves.

flux ,

^Zkill -9 %1 is the only way.

kill -9 -1 if that doesn’t work.

flux ,

It comes from the words “Eight Megs And Constantly Swapping”.

Yeah, the name hasn’t aged well…

flux ,

Just keeping a single frame buffer image can take tens of megabytes nowadays, so 100MB isn’t all that much. Also 64-bit can easily double the memory consumption, given how pointer-happy the ELISP data structures can be (this is somewhat based on my assumptions, I don’t actually know the memory layouts of the different Emacs data structures ;)).

But I don’t truly know, though. If I start a terminal-only Emacs without any additional lisp code it takes “only” 59232 kilobytes of resident memory. Still more than I’d expect. I’d expect something like 2 MB. But I’ll survive.

yabridge works really great for working with Windows plugins. I have quite a few of them working out just fine—at least with Bitwig, which is a native application.

That said, I’ve also seen some plugins that did not work. In particular the problems can be related to license management; they probably get confused of what kind of system it is running on…

In my view yabridge is easy to use, but on the other hand I have a decent amount of Linux experience, so perhaps the experience can vary.

flux ,

Do share if you have experiences using yabridge with the flatpak distribution of Bitwig! My existing setup did not work with that, but the deb version worked ok on Debian, so I keep using that.

flux ,

Thanks for the links! Once flatpak/yabridge works great I’ll be able to use it with SteamDeck :).

I wonder though if this might need some additional functionality in flatpak itself…

flux ,

There is the DJVU format for this exact use case, but you’d need to convert them to, say, pdf for many use case. Its also a bit old and perhaps not maintained, soo…

HEIF and other modern video encoders (HEIF=H265) should fare a lot better than JPEG, though.
