We get some, uh, character development with Destiny, we get introduced to Justice (and actual character development), and we have a brief encounter with lady-bird.

It was a bit hard to watch the end with all the foreshadowing that Natsuko was going to mess things up.

This is a text post, so the OP wrote text corresponding to the title. You should be able to see it at the top of the post. (Spoiler, OP is basically asking the community why NixOS is better, because they don’t quite understand the advantages of using NixOS.)

POP!_OS apparently uses systemd-boot (not to be confused with systemd). It apparently adds a Windows entry automatically if Windows is installed on the same disk. When Windows is installed on a different disk, it looks like booting the windows boot manager EFI program is still possible with systemd-boot. The instructions given in that link are a bit vague, though.

This page has a different, simpler approach and more specific steps. Apparently you can just copy the Microsoft EFI folder to a specific directory in your Linux drive’s ESP partition. I’d be a little bit concerned about Windows not being able to update its EFI bootloader, but I also don’t know if Windows ever updates that. The page also has instructions on how to interact with the systemd-boot menu during boot.

You could also install grub yourself, but I can’t guarantee that’ll be easy. Mashing F2 might be the sanest solution, unless you plan on booting into Windows every day.

I got interested, so I spent some time looking into what’s going on here. I’m not intimately familiar with X11 or Wayland, but I figured out some stuff.

Why sudo ip netns exec protected sudo -u user -i doesn’t work for X11 apps

Short answer: file permissions and abstract unix sockets (which I didn’t know were a thing before now).

File permissions: when I start an X11 login session, the DISPLAY is :0 and /tmp/.X11-unix/ has only 1 file X0. This file has 777 access. When I start my wayland session with Xwayland, the DISPLAY is :1 and /tmp/.X11-unix/ has 2 files X0 (777) and X1 (755). I can’t figure out how to connect to display :0, so I guess I’m stuck with :1. When you change to a different (non-root) user, the user no longer has access to /tmp/.X11-unix/X1.

Abstract unix sockets: When I start my wayland/xwayland session, it creates abstract unix sockets with ids @/tmp/.X11-unix/X0 and @/tmp/.X11-unix/X1. See ss -lnp | grep Xwayland. The network namespace also sandboxes these abstract unix sockets. Compare socat ABSTRACT-CONNECT:/tmp/.X11-unix/X1 STDIN and sudo ip netns exec private socat ABSTRACT-CONNECT:/tmp/.X11-unix/X1 STDIN.

When you do sudo ip netns exec protected su - user, you loose access to both the filesystem unix socket /tmp/.X11-unix/X1 and the abstract unix socket @/tmp/.X11-unix/X1. You need access to one or the other for X11 applications to work.

I tried using socat to forward X1 such that it works in the network namespace… and it kinda works. sudo ip netns exec protected socat ABSTRACT-LISTEN:/tmp/.X11-unix/X1,fork UNIX-CONNECT:/tmp/.X11-unix/X1. It appears having ABSTRACT-LISTEN before UNIX-CONNECT is important, I guess it would be worth it to properly learn socat. With this sudo ip netns exec protected su - testuser -c 'env DISPLAY=:1 xmessage hi' works, but sudo ip netns exec protected su - testuser -c 'env DISPLAY=:1 QT_QPA_PLATFORM=xcb kcalc' does not work. 😞

Changing the file permissions on /tmp/.X11-unix/X1 to give the user access seems to work better.

Wayland waypipe

Waypipe works as advertised. But it’s still a little bit tricky because you need to have two separate processes for the waypipe client and server, wait for the waypipe socket to be created, adjust file permissions for the waypipe socket file, and set (and probably mkdir) XDG_RUNTIME_DIR.

waypipe -s /tmp/mywaypipe client &
sleep 0.1
chgrp shared-display /tmp/mywaypipe
chmod g+w /tmp/mywaypipe
sudo ip netns exec protected su - testuser -c 'mkdir -p -m 0700 /tmp/runtime-testuser && env XDG_RUNTIME_DIR=/tmp/runtime-testuser waypipe -s /tmp/mywaypipe server -- env QT_QPA_PLATFORM=wayland kcalc'
kill -SIGINT %1

thanks, I’ll try out the libx264 encoder next time

Oh wow, I didn’t know (free) Davinci didn’t support using H.264 as source media, that feels rather limited.

Completely tangential tip, but in the very-limited video editing I’ve done recently: I’ve used Davinci Resolve, rendered as .mov, and then used ffmpeg to render to my actual desired format. e.g. h264 w/ aac audio so I can upload to Youtube:

ffmpeg -i input.mov -c:v libopenh264 -profile:v high -c:a aac -pix_fmt yuv420p output.mp4

I do think that finding the right flags to pass to ffmpeg is a cursed art. Do I need to specify the video profile and the pix_fmt? I don’t know; I thought I did when I adventured to collect these flags. Though maybe it’s just a reflection of the video-codec horrors lurking within all video rendering pipelines.

edit: there may also be nvidia-accelerated encoders, like h264_nvenc, see ffmpeg -codecs 2>/dev/null | grep -i 'h\.264'. I’m not sure if the profile:v and pix_fmt options apply to other encoders or just libopenh264.

Shows for Winter 2024 on my radar, that I am interested in watching:

• Classroom of the Elite: first two seasons were fun, looking forward to season 3
• Bottom-tier Character Tomozaki: first season was OK, I’m interested in where the story will go
• Mato Seihei no Slave: I vaguely recall someone saying there was something good about the source material
• MASHLE: first season was OK, I’m not very interested in S2, I might binge it when the season is complete
• Blue Exorcist: oh, another season. It’s been a while. I remember liking the first season and being confused at the start of the second season (it’s about 6 years between each season, so maybe I just forgot some important details. From a S2 MAL review: “the season does not follow the end of season 1. Episodes 18-25 were not canon and accordingly, they do not exist in season 2”, I didn’t know this, so maybe that was my problem)
• The Dangers in My Heart: first season was fantastic, excited for the second season
• A Sign of Affection: the source material is rated highly on MAL, I’ll give it a shot
• Banished from the Hero’s Party: First season was OK
• TSUKIMICHI: I liked the first season, looking forward to the second season
• The Foolish Angel Dances with the Devil: I saw the PV, I’ll give it a shot
• Cherry Magic!: The source material is rated well on MAL, I’ll give it a shot
• The Witch and the Beast: The source material is rated well on MAL, I’ll give a shot
• The Weakest Tamer Began a Journey to Pick Up Trash: WILDCARD, I dunno, it sounds like absolute trash from the title, but I think I’ll give it a shot anyways

haha, I didn’t think of Eminence in the Shadow. Oliver is almost living out Cid’s dream, with his secret special ability, secret special motivation, secret special ambitions, and secret special coronation.

Eminence in the Shadow really nailed it on the head.

Huh, lots of stuff going on in this episode. We finally get the titular seventh spellblade… Funnily enough, Bungou Stray Dogs season 5 also showcases the ability to cut through space-time that kinda makes the seventh spellblade look quaint.

Oliver’s motivations are revealed with a little bit of his mother’s (?!) backstory from seven (?!) years ago, but it seems like there is more to tell. Hopefully they also get around to explaining why there is a cult.

Looks like Oliver didn’t need the advice that Richard Andrews gave him last episode.

I’m not a huge fan of Iseleve, but I found enjoyment in it. For me it was a bit like watching a campy movie for fun, part of the fun was very much jeering at it with others. Everything is so over the top and absolutely ridiculous. Some parts are bananas, but not once does the show acknowledge its ridiculousness – it plays everything completely straight faced. It made me wonder: was it written this way because the author thought this Mary Sue would be super cool, or was it written this way because the author wanted to absolutely abuse a few tropes to the furthest extent that he possibly can. I don’t know what the truth is, it may be a mixed bag, either way the end product is fascinating to watch.

To enjoy the show, I think you probably also have to enjoy the Mary Sue & wish-fulfillment aspect to some extent. There’s just too much of it to ignore or jeer at all of it.

I think what I don’t like is that is feels like the MC is literally handed everything and there is no challenge whatsoever; for me it feels a bit like a story-on-rails feeling and I don’t feel really connected to any of the characters, as if they are just cookie-cutter templates with no depth or personality.

Absolutely, this show has little nuance. The characters don’t feel like real people. The plot and character development is asinine. The visuals were actually OK, there were a few pretty scenes.

I think the top review on MAL is worth a read if you haven’t read it yet https://myanimelist.net/reviews.php?id=490093 … Though be warned, that review may be more interesting than the show itself.

RIP Gojou. I guess he’s just too cool for TV.

But seriously, JJK continues to deliver episodes overflowing with style, an interesting plot, and great animation & sound & voice. It’s awesome.

It was interesting to see Nanami in this time period, I was not expecting to see him.

I just watched the first two episodes. It’s a pretty unabashed power fantasy with somewhat uninspiring animation, but I don’t hate it. Stuff is happening, our MC is relatable, our MC and friends are happy. I’ll probably keep watching.

Also check out !anime@lemmy.ml if you haven’t already.

With this episode we’re thrown right back into the plot. Ranpo is always a treat whenever he makes an appearance – he’s the real MC. They quickly touched on what was happening with all of our Armed Detective Agency friends, and overall it was a great start to the season.

There was a lot to dislike about this season but in the end the soundtrack and visuals always pull through.

I agree!

After the Red-Light District arc, I decided to lower my expectations around the narrative story telling and use of flashbacks. I love the action animation and soundtrack. I also enjoy the characters and the general concepts of the story arcs. But a lot of the story itself falls flat for me, and doesn’t show signs of changing. Perhaps it has something to do with who they see as their audience (more casual, might be doing something else while watching).

With that in mind, I quite enjoyed this season. My main disappointment was that they did the 2-fights-at-once thing again.

Geez, Yuuya wasted no time explaining the magic door and the alternate world. Learning that Yuuya has been using this magic door to adventure in this alternate world, Kaori has the totally normal response, “Has my relationship with Yuuya deepened?”. And, of course, Yuuya saves the day again.

The episode is topped off with indoor lightning for dramatic effect.
