Mastodon's federation is not at all consistent even when it could get much closer with a little effort.

Servers don't remote fetch old posts from recent follows for example, nor replies to off-server posts from people on a third server. There's work being done on both, but I'm surprised it wasn't prioritized much earlier. Some other Fediverse software handles these situations better.

I think Samsung put out a couple smartphones about a decade ago with 16:9 sensors, but otherwise phone cameras are almost universally 4:3. Nothing wrong with cropping intentionally of course, but I see a whole lot of images that appear to be cropped accidentally.

[-] [email protected] 12 points 9 hours ago

Random unsolicited photography tip: your phone camera's aspect ratio is 4:3. Setting it to something else crops the image, even if that something else is misleadingly called "full".

It looks like you had to back up to fit the whole poster in the frame, thereby including a bunch of carpet and ceiling. It would be easier to frame uncropped.

I think the fediverse has a built-in legal risk in that any time someone posts, data is sent to a large number of servers when then make it available via the web or sometimes push it to additional servers (e.g. by user boosts or community subscriptions). This is currently done without any explicit license for the IP contained in that post.

I'm inclined to think that irrevocable permissions are the right thing here, in large part because it's impossible to guarantee that any subsequent signal from the original poster propagates to everyone who has a copy of that post, or that the server software responds how someone else expects it will.

There is a legal basis: congress passed a law, the president at the time signed it, TikTok sued, and the Supreme Court unanimously ruled against TikTok. That's a legal basis by definition.

Perhaps you mean that there is no rational basis. That's a reasonable position you can argue for.

I use a variation of this approach to display fediverse comments on a statically-generated site. It does involve a manual post to Mastodon, but I'm not very inclined to redo the whole site.

[-] [email protected] 13 points 2 days ago

No single entity can ruin it. We've seen that happen over and over when someone's political or economic goals conflict with user interests.

BlueSky actually talks about this quite a bit, viewing the company as a potential future adversary of the current developers' goals. I'm not sure their design choices align with that in practice, but they articulate the argument well.

Another cool thing is the broader reach federation provides. Someone with a Wordpress site need only install a plugin and people can follow it with Mastodon and the like. Tag a community in a post and it shows up on Lemmy too. This is underused so far, but I hope to see it continue to grow.

And that is what I would recommend against, even on a server that does not ban that age. If someone's (young) age is relevant to a discussion they wish to participate in, I would suggest a throwaway account.

[-] [email protected] 5 points 3 days ago

Why do you care?

If it's just about following the rules as a matter of principle, I suggest not doing that. Nobody is checking, and saying your exact age on public social media is oversharing anyway.

If it's about content moderation being strict enough to satisfy some comfort level, I wouldn't rely on that, but I also think 13 is old enough to start learning there are shitty people online and how to deal with them, preferably with some adult support.

A fair number of my contacts from countries where this is true also have Signal. If you don't, I suggest installing it and seeing how many people are there.

If it's hard to remember who uses what, start conversations from the contacts app instead of one of the messaging apps; in most cases it will tell you.

I don't think any evidence has come to light that WhatsApp's end-to-end encryption of message contents is broken, but it's also impossible to prove that it is correct because the client is not open source.

Volunteers were told not to carry a weapon because of outcomes like this.

Let's try out the counterfactual: the assailant pulls out a rifle, aims it into the crowd, and nobody else in the immediate vicinity is armed. What happens next?

There's a small chance he was just trying to scare people and disrupt the protest, but that sounds like the prelude to a mass shooting to me. It's likely many more people would have died in that case. We can't know of course and neither could the security volunteer; he had to make a hard decision in a split second in an emergency. He had to weigh the risk of shooting when he did against the risk of waiting, and he had the disadvantage of fighting a rifle with a pistol; it's much easier to shoot accurately with a rifle, and the ammunition is more deadly.

For background, it's hard to make a flashlight that works well on both AA batteries (0.8-1.7V potential operating range) and 14500 Li-ion batteries (2.8-4.2V operating range) given that white LEDs need about 3V.

For a long time, companies would make lights designed for AA using a boost driver that increases the output voltage, do just enough so it wouldn't burn out with excessive input voltage, and say that 14500 size Li-ion was "supported". Max output would, indeed be brighter, but low modes were usually far too high, and the flashlights could easily damage batteries that didn't have over-discharge protection.

The Skilhunt M150 was one of the first lights to do a substantially better job. Using a Li-ion battery, it sent the power through a variable-output linear regulator so both battery types could have reasonable modes, and it would shut off to prevent over-discharge. Several competitors use a similar approach today, but linear regulators are inefficient; they just turn the excess voltage to heat.

The ideal solution is either to use a higher-voltage LED configuration and boost the output voltage for both battery types, or to use a driver that can both boost (increase) and buck (decrease) voltage efficiently. The Emisar D3AA is the only light on the market doing AA/14500 with a high-voltage LED configuration (three in series for ~9V), and I believe the new M150 will be the first one using the buck/boost approach (though it's possible Zebralight has done it in the past).

Some friends have safety concerns that mean they need to appear digitally as if they're inside the USA while being elsewhere physically. Standard commercial VPNs are easy to detect (else I'd recommend Mullvad), so they need an option that looks like a residential connection.

They could potentially DIY it by leaving a VPN server at a relative's house, but I'm asking here for subscription services. It's best if they have a Mac OS app that's foolproof, with a clear visual indication that it's in use, and a feature to block traffic if the VPN is disconnected.

tl;dr: what's the closest residential VPN to Mullvad?

I don't actually want to do this right now, but I do want to know if it's really decentralized yet. Completely looks like it means each of:

  • A client ✅
  • A personal data server ✅
  • A relay ❓
  • Labelers ✅
  • Feed generators ✅

It looks like the relay might be the bottleneck. If I'm understanding the protocol correctly, a relay could consume less than the whole network so it doesn't have to be ridiculously expensive to operate, but I'm not finding examples of people doing it.

I've been self-hosting email with Maddy for a bit, but haven't shared any of the addresses widely yet in part because I haven't set up a spam filter. I'm pleased with Maddy; there's much less to learn to get a server up and running with sane default behavior than with the email software of old.

Ideally, I'd like to go beyond just spam filtering and have something with arbitrary categories like newsletters and password resets. I would prefer that it learn categories when I move messages to IMAP folders from a mail client. Maddy can feed messages into arbitrary programs and pick a destination folder based on their output.

Web searches turn up a ton of classification programs, most of which seem to be more interested in playing accuracy golf with well-known corpora than expanding functionality beyond simple spam filtering.

I often use a commercial VPN service, which I suspect is not rare among Lemmy users. Most of the time, I'm able to post to lemmy.world, but on occasion I am not. The default web UI provides zero feedback, just a spinning submit button forever, but if I look in the browser dev tools, I can see it's being blocked.

I understand that some limitations are necessary to prevent spam and other abuse, however this is a very blunt instrument. The fact that I have a 10 month old account with consistent activity should outweigh any IP address reputation issues.

Perhaps the VPN limitations could be narrowed in scope to cover only account creation and posts from young accounts.
