I don’t know how to do it with KDE’s tools, but on the command line with ffmpeg you can do something like this:

ffmpeg -i video_track.mp4 -i audio_jp.m4a -i audio_en.m4a -map 0:v -map 1:a -map 2:a -metadata:s:a:0 language=jpn -metadata:s:a:1 language=eng -c:v copy -c:a copy output.mp4

Breaking it down, it:

• runs ffmpeg
• with three inputs (-i flag) – a video file, and two audio files.
• The streams are explicitly mapped into the result, counting the inputs from 0 – i.e. -map 0:v maps input 0 (the first file) as video (v) to the output file and -map 1:a maps the next input as audio (a), etc.
• It sets the metadata for the audio tracks -metadata:s:a:0 language=jpn sets the first audio track (again counting from 0…) to Japanese; the second metadata option sets the next audio track to English.
• -c:v copy specifies that the video codec should be copied directly (i.e. don’t re-encode – remove this if you DO need to re-encode)
• -c:a copy specifies that the audio codec should be copied directly (i.e. don’t re-encode – remove this if you DO need to re-encode)
• output.mp4 – finally, list the name of the file you want the result written into.

If you need another language in the future, I think the language abbreviations are the three letter codes from here: https://en.wikipedia.org/wiki/List_of_ISO_639-2_codes – but I’m not certain on that.

I think the term would be “necrobump”

That’s from old school forums where posting to a thread bumped it back to the top of the feed and thus thrust old info prominently into everyone’s view again. You won’t get that same bump effect with most sorts on Lemmy. (“New comments” sort might work like that though? I’m not sure exactly how that’s handled.)

otherwise everyone has moved on

It’s pretty rare to get much of a response even after just 24 hours or so – not just in terms of comments, but even for upvotes. I think after that point, posts are usually so far down people’s feeds that almost no one sees it any more. That probably also discourages most people from replying since basically no one will see it. (Maybe the poster of the thread or comment you’re replying to will see it, but probably almost no one else will if it’s more than a day or so old.)

Some people do dig through community archives and/or user profiles – particularly after a new thread is posted – and they’ll occasionally upvote old posts, but they very rarely comment.

Just the other day, I got a reply to a thread from ~6 months ago on kbin!

It was spam. :/

I quit YouTube along with reddit last summer. I don’t use alternate interfaces. I haven’t found a replacement for most of the niche content I liked to watch there – and yes, that sucks.

I’ve mostly been watching offline content (like DVDs and things I downloaded years ago) when I want video entertainment, and doing other stuff with my free time.

You might think that’d mean more time playing games given my interests, but I’ve found I’m a lot less enthusiastic about playing through games if I can’t watch an LP or two of it afterwards. So, I’m actually playing (and also buying) less of those than I used to too.

The Japanese text on the bottom of the left image says: Sapporo (Draft) Black Label beer. I can’t tell what the four characters under 生 are though. (Too blurry for me to figure out.)

Edit: those characters might be 非熱処理 – meaning unpasteurized.

It’s often in comments in the JS file(s) – sometimes with the licenses quoted entirely and sometimes in a form abbreviated by an automated code packer. Probably a lot of sites aren’t actually compliant with the terms of the licenses doing things that way, but IANAL.

I don’t know about KDE in particular, but I’ve had problems with USB mice waking various Ubuntu systems when they’re not directly connected (i.e. there’s a hub or KVM in between it and the computer). The workaround I used for that was to remove the mouse input (e.g. by carefully pressing a physical button on the KVM) – which was good enough for me – but I think there is a programmatic way to block particular classes of input from waking the system if some device is waking your system inappropriately.

Doing a quick search turned up this: https://askubuntu.com/questions/252743/how-do-i-prevent-mouse-movement-from-waking-up-a-suspended-computer – I can’t vouch for any of the specific techniques there though.

Worth noting that while I had a problem with the mouse specifically, other hardware could be causing your system to wake up.
