Lemmy super communities?
  • The way I've been thinking about would be to have the "meta community" be a separate thing from each individual community. Each individual community would opt in to joining, and would retain their own moderation and users, but the posts would be sort of cross posted to the meta community. The meta community mods largely just deal with removing posts that don't fit. All the comments go on the original instance of the post and are moderated there, so the meta community mods might be allowed to moderate those comments on an opt in basis.

    The idea is that it's for very similar communities across different instances, but because it's opt in there are probably other uses. The hope would be that each individual community could retain their vibe, while the meta community would have more of a firehose of content, and possibly filter some of those topics back down for more in depth discussion.

    I'd also love for individual users to be able to group communities for themselves, and for those to be shareable, which seems much quicker to implement.

    What happens when solar panels die?
  • Oh no not this again. These articles pop up all the time and they're kind of awful when put in context - like yeah solar panels aren't perfect, but they're pretty dang close honestly. It's great that they mention the stuff at the end about laser welding, but the rest of the article is kind of just fear mongering.

    Firstly, panels don't really go bad - the article mentions this. But that doesn't mean they have to be thrown away. Yeah, it makes sense to put 300w/m² panels on your solar farm and replace your old 200w/m² panels. But those old panels are generally still producing power, and can be sold as used for projects less focused on absolute peak efficiency. The old three Rs tell us, Reuse is generally better than Recycle.

    Secondly, panels don't randomly leech heavy metals. They sometimes have lead based solder, and contain small amounts of cadmium. If the panel is in tact in a pile or deployed it's all locked up within the panel and doesn't just jump out. It can leech out if you put ground up panels in an acidic landfill that leeches into the ground water - that's bad so we shouldn't do that, but we already don't and have even more regulation coming.

    Panels are mostly glass and aluminum by weight, they're not like 20% lead or anything crazy. Recycling them safely is not some kind of crazy future tech, just a matter of regulation and economics.

    Moreover, the amounts they contain are miniscule compared to what fossil fuels produce. As Nickelback says, look at this graph: graph showing oil based energy producing like 40 times more cadmium.

    from here

    Or this North Carolina paper:

    Every GWh of electricity generated by burning coal produces about 4 grams ofcadmium air emissions.21 Even though North Carolina produces a significant fraction of our electricity from coal, electricity from solar offsets much more natural gas than coal due to natural gas plants being able to adjust their rate of production more easily and quickly. If solar electricity offsets 90% natural gas and 10% coal, each 5-megawatt (5 MWAC, which is generally 7 MWDC) CdTe solar facility in North Carolina keeps about 157 grams, or about a third of a pound, of cadmium out of ourenvironment.

    from here

    And as far as total landfill waste its dwarfed by what fossil fuels produce, even just general consumer trash:

    from this paper via this blog

    For most panels it seems like the most polluting thing about them is that they are produced using our current grid and not other solar panels.

    shavette razor - some thoughts
  • Did you try a blade sampler pack? I find the feel of the blade to be way more pronounced than in a safety, especially anywhere sensitive. I tend toward much less aggressive blade in the shavette.

    I'm fairly sure that's just a launcher limitation, you can swap out the entire launcher to whatever you want. If you don't want something radically different I think lawnchair is still around.

    How Germany outfitted half a million balconies with solar panels
  • Love the idea and article, but...

    just 800 watts, enough to power a small fridge or charge a laptop,

    I want to see a laptop with an 800w charger.

    [Technology Connections] Thermoelectric cooling: it's not great.
  • aren't you still limited by ambient air temp because the hot side of the Peltier needs to be cooled by air anyway?

    No, that's why the baby fridge works. The peltier TEC in the fridge can produce temperatures below ambient, but generally not below freezing. Computer chip TEC coolers would go farther and push more power through the TEC and do things like water-cooling the hot side instead of a little fan.

    The reason they don't get used anymore more complicated. It's my understanding that basically TECs have a sort of limit on the amount of heat they can push from the cold side to the hot side, because moving more heat means more energy used and thus more waste heat. Apparently most modern chips are past that limit. IIRC, TECs can only move something like 100w of heat - past that and they start to heat themselves up because of waste heat. Modern chips can be like 300w.

    Sub ambient cooling also comes with a bunch of issues like condensation, so no one really uses it day to day. Also, chips are run so close to their limits now that cooling like that doesn't get you nearly the performance difference it once did.

    Can holograms be transported?
  • The light is immaterial (lol) to the holograms existence. They are only solid via fancy forcefield transmitted from the holo emitters. For all intents and purposes they seem to only exist as programs within whatever computer operates the holo emitters, whatever or whatever that may be. The only limit on where they can be is the speed of the computer system and links within it. They can send holo programs between the alpha and delta quadrants, but are limited by the speed and this can only send smaller programs. The mobile emitter often gets transported, but that's because they only have one. If the doctor is going somewhere with holo emitters they don't need to be transported and can just be data transferred.

    Personal rant follows:

    !The whole hologram plot in Voyager is honestly poorly thought out, and it basically feels like if you followed their logic Chat GPT would be a protected federation citizen. I get that the writers wanted to give the doctor legitimized personhood, but it feels like they forgot to think about what that would mean for literally every other hologram. !<

    !Like, they give that one species holograms to hunt, does that mean they invented a species doomed to be reincarnated as prey forever? Is, Moriarty sentient, and if so is trapping him in a simulation moral? If they just run a hologram long enough does it gain sentience? How are they testing for this? Does that mean Vic Fontane is sentient even though he probably would say he isn't? What about that weird Irish bartender Janeway does - fair haven ran for a while, how long does it take? If you run a training program are you committing infanticide? Is turning off a hologram even moral?!<

    This rabbit isn't rule
  • There's a pretty large combination of factors that went on from what I remember. Partly it just plain didn't get that hot that often in the UK or France back then. Partly they wore entirely different undergarments that layered to keep sweat off their actual clothes and keep them cool. Partly the summer clothes were often flowy or puffy which helped move air near the skin. And partly the fabrics they wore were different. Things like linen and cotton were the go tos. Even the linen itself was different, modern linen has shorter fibers and is much lighter.

    After the great renunciation (when men started wearing the modern(ish) suit) you start to see a lot more references to taking off layers either to cool off or to keep them clean or whatever. You also start to see variations in really hot places like the American deep south and Bermuda to deal with climates that get way way hotter than Europe with its nearby seas and cooling prevailing winds.

    Please note that all of this may be wrong and I am entirely going off what I can remember off the top of my head.

    Sky thing happen
  • Unfortunately probably not. G3 events aren't that uncommon, there's usually one every couple months. It never hurts to go look for a few minutes though. It's a pretty rough prediction, it's not set in stone. The best I've seen was a G4 and not the big G5 a few months ago.

    Long watch on war gaming, how it works, morality and its impacts on regular gaming.
  • Yeah, it feels like the entire time he's really trying to link these games to actual deaths during war that seems pretty tenuous, largely due to his own "ick" factor that "his thing" is being used by the military.

    The section in the middle where he essentially asks all his interviewees basically "have you killed anyone" is pretty awkward. Like, of course these people don't really want to talk about that. Nobody wants to go around thinking they're directly responsible for preventable deaths. It's like he wants someone to just say "Am i the baddie?" like that Mitchel and Webb sketch.

    It also completely glosses over the way that "play" is often just training for something more violent. Tag is a fun game until someone brings a knife. But there's a world of difference between "you sunk my battleship" and the Bismarck. It's like he's somehow taken the stance that video games cause violence in the most roundabout way possible.

    It's a shame because the video is good but it could be so much more interesting diving into examples about how these games actually work and are used instead of hemming and hawing the whole time over his imagined Cluedo to murder piperine.

    It genuinely upsets me that Valve spent their time and resources on another Dota variation
  • Ok, I'm a bit out of the loop but is Deadlock actually any good? Like, most of what I've heard is that it just isn't very fun. Even though they kinda fell apart the auto battler and the card game from Valve were generally fairly well received from what I remember. But everything I've heard about Deadlock is that it's not fun, and is bringing the worst elements of DOTA with it.

    Maybe since it's barely even a thing yet, it might wildly change since that's part of the Valve MO.

  • So, this will probably be possible when the link handler is implemented, but it would be really handy to be able to switch what account you are viewing a post with. I'm guessing it would be possible to share the post to the link handler and then there would be an account selector, but it would be nice if there was a slightly less roundabout way to do it.

    I'm on a smaller instance and browse all from the anonymous Lemmy.World account sometimes, but when I find a post from community that I'd like to subscribe to I have to copy and edit the post link to get the community link to search with. If anyone knows an easier way I'd love to know it.

    So, I've found that there are a lot of ways to backup a server and anything on it, but I'm somewhat at a loss for what to use to backup everything else to that server.

    For most stuff I personally can grab the files I need and back them up using a simple SMB share or rsync or whatever, but for my SO or anyone else who wants to back up is going to have a hard time. That doesn't even cover phones - which you would want to back up fairly regularly since, you know, they get dropped. Sure, I personally can hook up tailscale and split tunnel it, and then set up sync on certain folders, but nobody else I know is going to be able to.

    In a perfect world there would be a backup app that had its own little wireguard tunnel built in that could run all the traffic from wherever to my server, and would easy to set up on Android and Windows, but I don't think that exists. So what does everyone use that does exist?
