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?

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!

I'm curious what experiences people who game on linux have had, what your favorite distros are, and why. Mind sharing them in this thread? I'm in the market.

My old GTX770 just bit the dust. I picked up a Radeon 6600 to replace it, only to discover after installing it that while the 6600XT has Windows 7 drivers, the 6600 itself does not. The desktop works, but that's it. A little strange, but not entirely unexpected.

My ancient frankenstein Win 7 Enterprise has got to go (into a VM, already on its way) and there is simply no way in hell I will ever use any version of the spyware/bloatware mess that Windows has become today. They lost me forever the second they put a marketplace and ads into my start menu. Ain't nobody got time for that, or at least, I don't.

That means it's finally Linux time, for real - no going back. I'm rather excited. :D

Side note: My original install date for Windows 7 Enterprise was 11-12-2011, it's lasted nearly eleven years without a BSOD or the need to reinstall. They really did fix windows decay syndrome in v7. That's the longest I've ever had a desktop OS last. Can any desktop linux distro manage to go that long, I wonder?

The last time I ran a linux daily driver was Ubuntu for two years around '08, until I got sick of the pulseaudio issues. I'm not worried about that anymore, linux is ready for primetime now. That begs the question of which distro to use. I've toyed with or supported just about all of them at work (mint, redhat, suse, ubuntu, arch, deb, slack just to name a few). I'm a sysadmin by trade so I'm not phased by the learning curve, I know linux cold already.

It's more a question of which distro is going to bother me the least acting as my daily driver. I like to tinker at work, but if I have to do it all the time at home I get cranky. I prefer the 'it just works' experience. The primary requirement is linux gaming, as this is my main gaming rig. That means lots of Skyrim Special Edition, Stellaris, Rimworld, emulators, etc.

There's so many choices out there I'm not sure how to tell which one is the best and I don't particularly feel like putting a dozen of them through their paces over a month to find out - so I'm asking Tildes. ;) I don't mind trying a couple. Steam is required. Good support for WINE is a bonus. Ditto virtual desktop support - is Compiz still a thing or is there something better?

Here are the system specs. I'm sure it's all fully linux compatible.

1. Asus Maximus IV Extreme-Z
2. Intel i7 2600K (3.2GHz, OC'ed to 4.2GHz with a Noctua air cooler, never breaks 60'C)
3. Sapphire RX6600 GPU w 8GB of DDR6
4. 16GB of G.Skill DDR3 2400MHz memory
5. 500GB Samsung SSD, 4x4TB WD Red NAS drives

Yeah, it's long in the tooth, and I'm glad I went for the Z/K combo so the new GPU isn't entirely gimped plugged into a much older PCIe 2.0 mainboard. I'll pick up a Ryzen sometime to replace it, but not until after the chip shortage shakes out. It was hard enough getting that 6600 in this market without getting scalped.

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).

Even tech news moves a bit too fast for me to keep up. Did UMN ever get unbanned? I saw a half-hearted apology and then finally this [1], but never heard any update. Most recent article I've seen is this ZDNet article [2] from a couple of weeks ago discussing a related issue, but still mentions that UMN is still banned.

Anyone following this?

This below is a summary of some real-world performance investigation I recently went through. The tools I used are installed on all linux systems, but I know some people don't know them and would straight up jump to heavyweight log analysis services and what not, or writing their own solution.

Let's say you have request log sampling in a bunch of log files that contain lines like these:

127.0.0.1 [2021-05-27 23:28:34.460] "GET /static/images/flags/2/54@3x.webp HTTP/2" 200 1806 TLSv1.3 HIT-CLUSTER SessionID:(null) Cache:max-age=31536000
127.0.0.1 [2021-05-27 23:51:22.019] "GET /pl/player/123456/changelog/ HTTP/1.1" 200 16524 TLSv1.2 MISS-CLUSTER SessionID:(null) Cache:

You might recognize Fastly logs there (IP anonymized). Now, there's a lot you might care about in this log file, but in my case, I wanted to get a breakdown of hits vs misses by URL.

So, first step, let's concatenate all the log files with cat *.log > all.txt, so we can work off a single file.

Then, let's split the file in two: hits and misses. There are a few different values for them, the majority are covered by either HIT-CLUSTER or MISS-CLUSTER. We can do this by just grepping for them like so:

grep HIT-CLUSTER all.txt > hits.txt; grep MISS-CLUSTER all.txt > misses.txt

However, we only care about url and whether it's a hit or a miss. So let's clean up those hits and misses with cut. The way cut works, it takes a delimiter (-d) and cuts the input based on that; you then give it a range of "fields" (-f) that you want.

In our case, if we cut based on spaces, we end up with for example: 127.0.0.1 [2021-05-27 23:28:34.460] "GET /static/images/flags/2/54@3x.webp HTTP/2" 200 1806 TLSv1.3 HIT-CLUSTER SessionID:(null) Cache:max-age=31536000.

We care about the 5th value only. So let's do: cut -d" " -f5 to get that. We will also sort the result, because future operations will require us to work on a sorted list of values.

cut -d" " -f5 hits.txt | sort > hits-sorted.txt; cut -d" " -f5 misses.txt | sort > misses-sorted.txt

Now we can start doing some neat stuff. wc (wordcount) is an awesome utility, it lets you count characters, words or lines very easily. wc -l counts lines in an input, since we're operating with one value per line we can easily count our hits and misses already:

$ wc -l hits-sorted.txt misses-sorted.txt
  132523 hits-sorted.txt
  220779 misses-sorted.txt
  353302 total

220779 / 132523 is a 1:1.66 ratio of hits to misses. That's not great…

Alright, now I'm also interested in how many unique URLs are hit versus missed. uniq tool deduplicates immediate sequences, so the input has to be sorted in order to deduplicate our entire file. We already did that. We can now count our urls with uniq < hits-sorted.txt | wc -l; uniq < misses-sorted.txt | wc -l. We get 49778 and 201178, respectively. It's to be expected that most of our cache misses would be in "rarer" urls; this gives us a 1:4 ratio of cached to uncached URL.

Let's say we want to dig down further into which URLs are most often hitting the cache, specifically. We can add -c to uniq in order to get a duplicate count in front of our URLs. To get the top ones at the top, we can then use sort, in reverse sort mode (-r), and it also needs to be numeric sort, not alphabetic (-n). head lets us get the top 10.

$ uniq -c < hits-sorted.txt | sort -nr | head
    815 /static/app/webfonts/fa-solid-900.woff2?d720146f1999
    793 /static/app/images/1.png
    786 /static/app/fonts/nunito-v9-latin-ext_latin-regular.woff2?d720146f1999
    760 /static/CACHE/js/output.cee5c4089626.js
    758 /static/images/crest/3/light/notfound.png
    757 /static/CACHE/css/output.4f2b59394c83.css
    756 /static/app/webfonts/fa-regular-400.woff2?d720146f1999
    754 /static/app/css/images/loading.gif?d720146f1999
    750 /static/app/css/images/prev.png?d720146f1999
    745 /static/app/css/images/next.png?d720146f1999

And same for misses:

$ uniq -c < misses-sorted.txt | sort -nr | head
     56 /
     14 /player/237678/
     13 /players/
     12 /teams/
     11 /players/top/
<snip>

So far this tells us static files are most often hit, and for misses it also tells us… something, but we can't quite track it down yet (and we won't, not in this post). We're not adjusting for how often the page is hit as a whole, this is still just high-level analysis.

One last thing I want to show you! Let's take everything we learned and analyze those URLs by prefix instead. We can cut our URLs again by slash with cut -d"/". If we want the first prefix, we can do -f1-2, or -f1-3 for the first two prefixes. Let's look!

cut -d'/' -f1-2 < hits-sorted.txt | uniq -c | sort -nr | head
 100189 /static
   5948 /es
   3069 /player
   2480 /fr
   2476 /es-mx
   2295 /pt-br
   2094 /tr
   1939 /it
   1692 /ru
   1626 /de

cut -d'/' -f1-2 < misses-sorted.txt | uniq -c | sort -nr | head
  66132 /static
  18578 /es
  17448 /player
  17064 /tr
  11379 /fr
   9624 /pt-br
   8730 /es-mx
   7993 /ru
   7689 /zh-hant
   7441 /it

This gives us hit-miss ratios by prefix. Neat, huh?

Last time I owned an inkjet was well over a decade ago. I had a nice HP color laserjet that Just Worked™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.

I've put quite a bit of work into my i3 set up recently and I'm curious if the people here are interested in that kind of thing.

I'd be interested in looking through configs to get ideas, and sharing screenshots and such.

Here is what my desktop looks like right now. Let me know what you think.
