Lemmy is sort of crappy through its software decisions, similar to how Reddit is crappy but in some ways worse. There’s not much we can do about that as users. Reddit also manages to paper over some of its crappiness through moderator interventions, while Lemmy tends to let crap slide. Crappiness = clickbait titles with no indication of what the link is about, lots of duplicate posts, etc. Lemmy adds the problem of fragmenting communities across instances. I think I heard that posts duplicated across multiple communities in a single instances will somehow be cleaned up in 1.0, which can help.

Anyway there’s not a whole lot that users can do, except maybe launch some new instances or forks that don’t suck as much.

How can I wipe the dust in a way so as to avoid just pushing it around so much?

Vacuum it. My friend has a Roomba that does her whole house automatically. I thought those things were ridiculous until I actually saw it.

Also, as someone said, air filtration should get some of the dust out of the air. That is healthy for breathing. If you don’t mind the noise, you can make a powerful air filter from a box fan and 4 furnace filters: look up “Corsi-Rosenthal box” for how to do that. Otherwise you can get a smaller one.

So find the places where the bitrate changes and decode and analyze those frames. Outdoors, true, leaves blow around, there is wildlife etc. A harder problem. I was thinking more of an indoor security camera. As for examining the bit rate, I guess it depends on the encoding, but e.g. in .mp4 there is a “key frame” every so often and then a bunch of delta frames, and if stuff is changing too fast iirc the key frames become more frequent. But I believe there is a fast way to scan for them, that is needed for fast forwarding in video.

I have to wonder if there’s a faster way than literally decoding the video and analyzing the decoded frames, if that’s how you’re doing it with ffmpeg. Video compression revolves around motion estimation so maybe it’s possible to just scan the file and find frames where the motion vectors (the data saying how the stuff in the picture is changing at a given frame) suddenly get larger. I assume this is for something like a security video that usually shows a static picture, and OP wants to flag when someone enters the room. In that case there will be almost no motion most of the time, and suddenly there will be some.

One thing that can help (more for libraries than large applications) is “dependency cooldowns”. Basically don’t use the latest version of anything until a few weeks after its release. The hope is that most malicious changes or blatant bugs will be caught fairly early.

generally, use “netstat -lpn | grep 8080” (or whatever port number) to find out what process is already listening on that port. This kind of thing happens all the time.

Those aren’t really sufficient reasons to deal with vinyl IMHO. Do it because you want another weird expensive hobby maybe, or because there’s music you like that you can’t easily get in other formats. Or you like full sized album art, etc. Otherwise in practical terms it’s mostly not worth it, IMHO.

I was into it back in the day. But I found when I bought a new LP, I’d usually dub it to tape cassette on the first listen. After that I’d usually play the tape instead of the LP just because it was less hassle.

These days just rip everything to FLAC and transcode that to other formats as the need arises. It’s on your HDD so you still own it. Make backups of course.

Modern leftist community that keeps clamoring to defederate lemmy.ml which tbh isn’t that political? Nah.

In military systems it’s done with e.g. frequency hopping with encrypted sequences. That’s also how GPS anti-spoofing works (that’s for the military segment of GPS). The idea is say there are 1000 frequencies and you keep switching between them. Since the jammer doesn’t know which one you’re using at any moment, they have to jam all 1000 of them. So that increases their power requirements by 1000x compared to jamming just one frequency.

It’s not feasible for a mass market consumer product like Starlink. Even if it was, it would be thrown under sanctions or military suppression faster than you can say boo. And it would run at quite low bit rates to again maximize the ability to get through jamming. It would be useless for Netflix or transmitting video.

Maybe an activist cell in a place like Iran could put something together for its own members on the quiet, but it would be low bandwidth and would presumably be very dangerous for the users if they got caught. It seems likely to be that low bit rate digital ham radio modes like PSK4 or JS8CALL could get through Iran’s jamming, and the hardware is pretty accessible. But, they could use direction finding to clobber the transmitters. Low bit rate = 1 character per second, say. So you could essentially smuggle text messages out of the country, not video. Maybe if they aren’t looking, you could get a voice channel through. On the other hand, is it possible to make phone calls in or out of Iran right now? I doubt that the country would disconnect itself completely enough to stop all phone calls, but I haven’t been following the situation. I think it’s possible to even call into North Korea though.

I wonder sometimes if people overestimate the usefulness of stuff like this. Suppose Iran’s efforts to jam Starlink had failed, so Starlink still worked there. What would be different for anyone? We’d see more video getting out, but it’s not clear to me that it would have any effect other than to stoke up more internet rage. It’s unclear to me if that’s of any help any more.

Starlink was apparently believed to be unjammable until recently, when we found out that it wasn’t, fwiw.

Meh, it’s sort of an empty gesture, as discussed in the HN thread. The “competitor” is a somewhat-compatible Teensy 3 clone that uses a different processor with roughly similar cpu performance. It doesn’t compete with the much faster Teensy 4 which is the only model that PJRC currently sells. And these types of boards aren’t generally about CPU performance anyway. If you want fast computing, get a Linux board or similar. These boards are about stuff like analog i/o.

bit.ly? They may have degoogled but they still stopped too early.

This is big stupid drama but there’s a long thread about it on hackernews.

Havana syndrome as a DIY project, great. :(

Ars technica is usually legit.

Ansible playbook.

Why do TV’s and audio gear use memory? TV’s ok I can sort of understand a little, but audio? That’s still analog right? Or anyway mostly analog.

Meaning fuel powered generators? Bah.

I’d DIY it (maybe with FreeNAS, about which I know nothing) instead of buying a proprietary NAS in a box. What’s the point of self-hosting if you’re going to be at the mercy of someone else’s software anyway? If you’re DIY’ing, there are 3.5" drive enclosures with soundproofing stuff in them that should keep the drive pretty quiet. Or if you can afford enough SSD’s for your storage requirements, then use those.

Water from the kitchen faucet. I better not tell them though. Some TikTok post about it will go viral and that will be the end of it for those of us who just want to stay hydrated in peace.
