    1. Can someone explain the systemd controversy to a nontechnical user?

      A project I'm working on requires me to cover a bit of comedy targeting Lennart Poettering as it's tangentially related, and I'd like to have more context even though it's not strictly necessary. I'm a nontechnical Linux user who used the OS before systemd came around, but really the only impact on my life it's had is that I occasionally use systemctl to control services.

      Though I wasn't paying as much attention to the community around the time major distributions switched, I've been casually exposed to criticism of it ever since I came back, and I'd like to make sense of it all and form an opinion beyond "I like Fedora and GNOME and it seems to go hand-in-hand with those". I've read The Biggest Myths, the Wikipedia article, some stuff on freedesktop.org, and of course absorbed the venom slung back and forth over systemd in every FOSS community, but it's hard to get a full picture. And a picture from 2022, for that matter, as a lot of this information comes from its early days. Help me out?

    2. Product recommendation request: low latency wireless earbuds

      Alright, so I fell down a rabbit hole of trying to understand a whole bunch of techy things that I don't fully understand and could use some help:


      What I'm looking for: a pair of Bluetooth wireless earbuds that I can pair with my computer, with low enough latency that it won't impair my enjoyment in casual gaming/video watching


      What I understand so far: Almost nothing. 😔 I get that Bluetooth will always have some level of latency, but, beyond that, I've got nothing. I'm so confused.

      There are lots of different versions of Bluetooth, and then there are different Bluetooth protocols within that, and then different audio codecs, and each piece of hardware seems to support completely different combinations of those, and I'm not sure if the devices have to match configurations or even how to figure out what my computer supports? It seems Bluetooth will gracefully fall back to worse codecs/protocols if better ones are incompatible, but I don't really want to buy something that's just going to fall back to its worst usecase.

      I also don't know what's an "acceptable" level of latency. What's reasonable versus what's intolerable?

      It also seems like the information I read online is subject to rapid decay. I read a bunch of stuff only a few years old saying I should look for aptX Low Latency capability, but then I read very recent posts saying that's dead and to go with aptX Adaptive instead. Meanwhile there are a handful of gaming-focused headsets that say they're low latency but don't really say how (e.g. Razer's Hammerhead). And some, like Samsung's buds, having a "gaming mode" but it only works on special hardware.

      Also, how do I know what my computer itself will support? Is there anything I can do from the computer side to reduce latency, or is that strictly a function of what my hardware supports and which earbuds I buy?


      My usecase:

      My computer is a System 76 Oryx Pro (5) running Pop!_OS 21.10. I think its Bluetooth adapter is version 5.1 (though I'm not confident on that). I do not know which protocols/codecs it supports, nor how to find that out.

      Audio quality isn't too important. These will be for everyday video-watching and gaming, which is what's prompting the latency requirement. I'd rather them be responsive than rich.

      Active noise cancelling would be nice to have (especially if it has a toggleable transparency mode), but I don't know if ANC adds latency and is therefore incompatible with what I'm wanting.

      I don't have a specific budget for it, and that's honestly the least important requirement. If the solution exists I'm fine paying for it (within reason, of course). These will end up getting used for thousands of hours, so even a big price difference upfront will even out over time.

      I'd appreciate any help anyone can offer in pointing me in the right direction on this!

    3. Help needed: slow external hard drive

      I've got a 2TB Toshiba drive (formatted as NTFS) that has become very slow and I was wondering if anyone here as any ideas what the problem could be and how I could fix it. All the data I'd need off the drive is backed up, but I would at least like a drive to put it back on to!

      In short, it became slow after I had to force power-off the system it was connected to (Pop OS installed on another external drive which I unplugged by mistake) and I haven't bothered to try to fix it in the six months since.

      I've tested it on Pop and it takes about 10-20 minutes to mount, and 2 minutes to unmount and safely remove. The data itself seems fine but performance is slow, accessing a 20MB image takes several seconds and selecting the drive in GNOME Disks caused it to freeze.

      The drive sounded louder than normal, especially after plugging in.

      On Windows, the drive was recognised and browsable immediately, but browsing through folders was very slow - opening some folders causes Windows Explorer to freeze for a while. Some of my double-clicks were mis-recognised as click-to-rename, which took several seconds to activate and during which time Task Manager reported the average response time between 5000 and 11000 ms.

      Attempting to load an audio file resulted in lots of buffering. Task Manager reports an active time of 100% (even when not loading files or folders) and the activity never exceeded 100 KB/s (and doesn't sustain it for more than a second). Ejecting the drive takes forever - after ejecting it using the tray icon, the tray icon is not removed (even though there are no other drives connected or listed) and the active time is still 100% with the indicator LED blinking non-stop. The system did not enter sleep right away after me asking it to either.

      All of that to say, does anyone know what the issue could be, or how I could find and fix it? Thanks!


      Edit: fixed and normal functionality restored (at least so I can check the drive a bit easier) using Scan & Repair in Windows (see my comment).

    4. Can anyone recommend a printer? (...ahem...) a Linux printer?

      Last time I owned an inkjet was well over a decade ago. I had a nice HP color laserjet that Just Workedâ„¢for almost a decade (and PS, I bought it used), and then I just lived w/o a printer for the past 3-4 years. Now, I'm window-shopping for inkjets, it sounds like the whole "use-our-ink-or-die" business model has only gotten worse.

      Are there any good inkjet printers where I can just use it like a normal printer, just buy ink (cheaper than the printer was) when I need it, yada? Or should I just write off the entire industry (again), and go straight to the laser printers?

      And does anyone actually have a decent (color, all-in-one) printer that works reasonably well with their (YourDistroHere) Linux machine?

      Danke


      ETA: Thanks for all the feedback. I'm now prioritizing a Brother laser (maybe just mono), or possibly an Epson Ecotank.

      Side-note ... how cool is it that we have so many Linux-folk in our midst!?

      Thanks again.

    5. What should a lay user know about Linux app packaging?

      I’m enough of a Linux lay user that I’m not even sure if I’m using the right terminology in the question (feel free to tweak it if needed!). Here’s what I mean:

      I’m running Pop!_OS currently, and I have at least one app installed via each of the following methods:

      • Deb app from the distro repositories
      • Deb deb downloaded from program website
      • Flatpak app downloaded from Flathub
      • AppImage app downloaded from program website
      • Snap app downloaded from the Snap store

      As someone who doesn’t really know or necessarily even care to know what’s going on under the hood, these all pretty much work identically for me (with the exception of AppImage which doesn’t integrate into my regular programs menu, and the standalone Deb, which requires manual updating). In fact, for most of the programs on my computer I couldn’t tell you which one they’re sourced from. They all just run like they should.

      I’ve looked up differences between all of the options and usually end up finding conversations that go well above my head and get deep into technical details. My question here is basically aimed at cutting through a lot of that depth: what is the important, need-to-know information about these different methods of installing apps? Is there anything I should be aware of if all I’m really going to be doing is running them as a standard, non-power user? Also, if an app is available via multiple methods — is there one that is preferred/better/safer/superior/etc.?

    6. [SOLVED] Tech Support Request: Finding the biggest files of a specific type

      Hey Tildes!

      I need some help with a specific tech issue, and I'm sure someone here can help me do it way quicker than I would be able to on my own.

      General Request

      I'd like to be able to scan a directory and find all of the largest files of a specific type (e.g. the largest .jpg files). I'm running Pop!_OS and I'm assuming there's some way to do this in the terminal, or alternately some utility I could use.

      More Specific Details

      I'm cleaning up my digital music library, and I realized in setting it up I made some errors by saving some very high res cover art. Many of my Bandcamp purchases come with a cover.jpg or cover.png file that is several megabytes large. I made the mistake of writing these into the files (adding, for some albums, an extra, say, 100 MB across all tracks). They also take a lot longer to load when I pull them up in my cloud music player. I'd like to be able to identify the albums with the largest cover.* files so that I can go in and replace the album art with a lower res version and gain back all that wasted space lost to unnecessary duplication.

      I could go folder by folder and take a look at the sizes of each, but I figure there's an easier way to surface the ones that need my attention. Everything I've looked at online so far has helped me figure out how to identify the biggest files in general, but all that will do is surface the actual audio files, when it's the cover art that needs the specific attention.

      Also, in case it's necessary information, the directory structure is Music/[artist]/[album]/cover.*

      Any help will be very appreciated!

    7. Ubuntu sends http requests to Google cloud, here’s a fix

      Ubuntu has this package installed by default:
      network-manager-config-connectivity-ubuntu

      It's only purpose is to provide settings for NetworkManager to send requests to connectivity-check.ubuntu.com , and based on the result (AFAIK) detect redirection by captive portals and open an ISP's page (think public WiFi, or hotel rooms, where you need to authorize to access the net).

      Well, connectivity-check.ubuntu.com is hosted on Google cloud (you can check that by running:

      dig connectivity-check.ubuntu.com
      whois [the IP from previous query]
      

      ), so by default Ubuntu sends requests to a Google cloud page.
      I don't say Google counts daily active Ubuntu users (because many of those have the same IP), or that Google actively logs and analyzes that data. But some of you guys may not like that behavior.

      So what's the fix?

      Purge the package

      sudo apt purge network-manager-config-connectivity-ubuntu
      

      If you do need a captive portal detection, create your own config file to query some HTTP (not HTTPS) page of your choice, in the example below I have a Debian page used for the same purpose. Use your favorite text editor to create and edit /etc/NetworkManager/conf.d/90-connectivity-custom.conf :

      [connectivity]
      uri=http://network-test.debian.org/nm
      

      Restart NetworkManager

      sudo systemctl restart NetworkManager
      

      If you run an Ubuntu derivative, please report if you have network-manager-config-connectivity-ubuntu installed in the comments.

    8. Librem 5 mass production phone has begun shipping

      Announcement

      Details on the phone itself (Both are the same, the USA refers to supply chain):
      Libram 5 - $799
      Libram 5 USA - $1999

      I think it's quite a tell about how much our electronics are subsidized by sourcing from inordinately cheap labor compared to the (mostly) German/USA labor for the USA phone.

      PureOS itself looks like it could be a decent entrant to breaking the mobile duopoly. The only sticking point for me would be various applications that don't offer browser options (read: 2 factor authentication apps).
