  • I'm assuming you didn't watch the video, but this particular helmet design has a completely open bottom. the only thing keeping the water beneath you out is the positive pressure from the air hose. Any excess air flows out the bottom.

    it needs weights attached to it to keep it from floating (he attached just enough weight to keep it neutrally buoyant). If it sprung a leak, you would easily be able to remove the helmet either by lifting it up off you, or tilting forward or to the side and sliding it off. it is not strapped to the person at all.

  • Not OP, but XMPP and Delta chat are good options.

    For XMPP, the Movim client in particular is a good replacement for Discord, since it can do audio/video calls, as well as screenshare, and Discord-like spaces (channels with groups of rooms).

  • I've only driven through Columbus Ohio once via highway, so I don't have a complete picture of it, but all I remember about it is it had the worst highway layout of any I've experienced, and it had the ugliest, most souless corporate signage along the road that I've ever seen as well.

    I also stopped to get some fast food, and immediately had a couple people loudly mock me for wearing a mask after I let them ahead of me while I was looking at the menu.

    The place just left me with really bad vibes, honestly.

  • The only advantage of the non-a models is they use a potentially more durable battery that is less prone to pillowing.

  • These aren't really that effective compared to a hollow point. They create a big visual in ballistic gel, but in a more realistic medium they act more like an improved FMJ, but still over penetrate badly (which isn't a good thing in most cases).

    They tend to be recommend as a bear round, where over-penetration is actually valuable and desired.

    The same manufacturer actually makes a deeper cut version that doesn't over penetrate called the xtreme defender, which is generally still worse than a good hollow point in standard calibers, but can be a good option for weaker calibers like .380, where hollow point under-penetrate.

    however, for 9mm and above, you're better off with a standard hollow point, which is more effective and far more affordable than the all-copper xtreme rounds.

  • I’m this close to saying “fuck it” and wasting the next couple of years of my life on a new protocol that no one is gonna use.

    This article does a good job exploring the landscape of text chats, and ultimately finds that XMPP is still our best bet, it just needs some spit and polish.

  • I want to point out that the author of that linked blog, Soatok, actually removed a response in the comments from an OMEMO developer which clarified some things, which personally I think was rather odd/bad faith of them to do. When asked about it, this was their response:

    "I'll make an edit later about the protocol version thing, but I'm not interested in having questions answered. My entire horse in this race is for evangelists to f** off and leave me alone. That's it. That's all I want."

    According to the OMEMO developer in his response (you can it read here), there's nothing really wrong with OMEMO 0.3.0, as the dev considers it a stable standard that clients can safely implement, with newer versions basically being public beta releases toward a stable 'OMEMO 2' standard that can eventually replace 0.3.0.

  • On the second point, Lemmy/piefed have the ability to export your profile to be imported into any other instance. It allows you to keep your subscriptions, favorites posts/comments, and blocked users/communities.

  • Pretty much all industrialists, tech-bros, and billionaires will be screeching that the world over, as there's virtually no place left that isn't chock full of multinational corporations. I guess they turned out to be the final boss for humanity.

    I'm rooting for us pulling through, but it'll take global grassroots organizing, militant unions, and a shit ton of mutual aid to prevent them from literally killing us all due to their mindless greed and lust for power.

  • I've been following them for a while. They have a solid reputation from what I know, and I think they do a good job of explaining recent climate studies in layman's terms.

  • The short version is as the title suggests, warming accelerating pretty dramatically, and based on recent studies we're fast approaching a hump that if we cross over, would likely result in a runaway situation that could not be fixed on human timescales. It's getting so bad even business analysis of the issue is suggesting drastic changes, such as not waiting for market forces to transition away from fossil fuels, but instead suggest governments globally super-charge the build-out of renewable energy sources.

    What isn't said in the video: Basically unless we get off capitalism very soon (especially combined with the knowledge from a different study that suggests the atmosphere may become toxic to humans in the later half of this century), we're potentially looking at mass extinction much sooner than expected if we continue with our current way of life.

  • His design is essentially a diving bell helmet with a pressurized feed of air from an air compressor, so the lungs don't have to overcome breathing through a snorkel. He plans to use it in shallow areas around Florida, he was only testing it in his pool.

  • I've found that Ubuntu still has by far the easiest one-click Nvidia driver installer of any distro, and switching between driver versions (such as rolling back if a new driver is buggy) is also far easier on Ubuntu.

    I say that as someone who does not like Ubuntu in most other aspects.

  • From what I understand, Piefed instances will have better support for Mastodon posts, and I believe it supports subscribing to Peertube channels already (something that Lemmy still doesn't support...) Edit: It does support Peertube!
