  • Xmpp definitely wins in privacy. What is there to privacy more than message content and metadata? Matrix definitely fails the second one, and is E2E still an issue for public groups? I don’t remember if they fixed that.

    XMPP being a protocol built for extensibility means it will be hard for it not to keep up with times.

    Okay so how does modern XMPP protect this? When I last used XMPP, some (not all) clients supported OTR-IM, a protocol for end to end encryption. And there wasn’t a function for server stored chat history (either encrypted or plaintext).
    Have these issues been fixed?



  • (This is not an insult, I just had a realization that I think might affect you)-- do you know what the name comes from?

    Years ago there was a thing called a beeper before everyone had cell phones. It was a one way paging system-- you’d give your friends your beeper number, they’d call it, type in their phone number, and their number (or whatever they dialed in) would appear on your beeper. You’d then use a landline phone to call them back (early versions of the system had no text or reply capability, only numbers and only one-way).

    I always thought it was a cool name. But thinking about it I realize someone less than maybe 25-30 years old might literally have never encountered such a device. Much like a 5.25" floppy disk or rotary dial phone, they went out of style years ago and a young person might never have encountered one.

    Curious if that’s you?



  • This is really not accurate. Matrix is not designed to be a super privacy first protocol. It’s like Lemmy in the it’s designed to solve a problem and be a useful federated collaboration tool. It borrows features from a number of popular messaging platforms. Message history is stored on the server but encrypted client side so privacy is preserved. It supports group chat rooms. It supports voice and video. And most importantly, it supports bridges- you can connect your matrix to other services that are completely incompatible with matrix using a bridge. Perhaps the best example of this is Beeper, which is built on matrix. They are trying to replicate the user experience of the old app Trillian- beeper can link with a number of chat services including Google messages, slack, WhatsApp, telegram, signal, etc. Thus you get all your chats in one place.




  • What you see in movies is bullshit. Any explosion creates a huge fireball and people go flying in every direction. Actual munitions aren’t like that. Especially munitions that have to be carried on light little drones. That includes most hand grenades and air-dropped bombs.

    I’m concept, an explosion that creates that big fireball puts most of its energy into spreading burning fuel around to create that big fireball. It’s visually impressive, but not actually very destructive. In warfare you don’t care what it looks like, you want it to be destructive. And the best way to get bang for your buck so to speak with an explosive that has to be lightweight, is with shrapnel. An explosive wrapped in shrapnel is not visually impressive to watch, but it basically sends little bullets flying out in every direction and those bullets are what does the damage.

    So consider it this way. If I walk up to the jamming device and shoot it with a pistol, it’s not going to be visually impressive. Nothing is going to fly apart and explode in a shower of sparks and flames. The jammer device might not even move at all, it just now has a hole in it. But it is in fact quite thoroughly destroyed because the bullet from my pistol destroyed all of its internal workings.

    Same thing is true with the grenade. The hand grenade is designed to be light and effective, so a soldier can carry it without getting weighed down. Thus it is a small explosive wrapped in a lot of shrapnel. Soldier throws it at the enemy, enemy casualties come not from the explosion but from shrapnel wounds. Drop one of those grenades next to a piece of equipment that isn’t armored, and it may not even appear to move, but it has been quite thoroughly punctured by shrapnel and is thus destroyed.


  • the top end models of the good brands are just scams, they just look a bit nicer and have some shitty “AI powered” app you’ll never use.

    This is literally a scam.
    There was an article a while back which I can’t find right now, a few of those product designers were saying that past $100-$150 they really weren’t sure what benefits could be added so they just throw a bunch of useless whiz bang shit in that serves no useful purpose but they sell it for $300 or whatever and enough people buy it to make it worth building another SKU.

    In most cases the super top end one has the same motor as the midrange or low-midrange one, and takes the same brush heads, which means it does exactly the same thing. Buy that one for $85 and be done with it.


  • Don’t participate in wanton consumerism.

    This is the answer. And it comes with other benefits also.

    I do okay financially. I don’t have problems affording necessities. But I have found there is also a lot of satisfaction in being more self-sufficient, in relying less on supply companies to deliver my every need. And it saves a ton of money.

    Food is a big one. I used to spend a ton of money on takeout, delivery, junk food. But here’s the thing, basic cooking really isn’t that hard. It doesn’t have to take up a lot of time, especially if you meal prep. And the resulting food is both better in quality and better for you.

    On that same thread, the grocery store is not always your friend. Especially if it’s one of the big national chains. You will find much better quality produce at your local farmer’s market, and it’s often cheaper too. Certainly way more flavorful, the vegetable that was in the dirt yesterday tastes way better than the one that’s been in a warehouse for a month. Happier chickens lay tastier eggs. Etc.

    And there’s a lot of stuff you can do yourself. A vegetable garden is a great place to start, if you have even a tiny backyard. Think folding table size. Plant yourself some tomatoes and put up a net frame so animals don’t eat them, they will be the best tomatoes you’ve ever had. But planting and growing stuff is one of the most efficient ways to get food- Stick it in the dirt and water it and you get food for free!

    Then think about all the shit we buy. How much of it do we really need? How much of it ends up in the landfill in a year or two? When purchasing things, think about the product entire life cycle and how each step will affect you. IE, Don’t just think about the dopamine rush you’ll get from unboxing your shiny new toy, or the novelty of using it the first couple times, ask yourself is it going to enhance your life owning it over the long term, and is that amount of enhancement worth its purchase price and the space it consumes?



  • This is not particularly interesting news From what I have read, North Korea is constantly sending extreme threats to South Korea, we will annihilate you, we will kill all your citizens, we will destroy your government, there will be nobody left when we’re done, etc etc etc. And by constantly I mean on a near weekly basis, to the point that South Korea basically stuck a trash can under the fax machine and stopped paying attention. North Korea can barely even feed its own citizens. And when you see the photos of Great Leader inspecting their amazing new military technology half the time it’s computers from the 1990s that aren’t even plugged in correctly.





  • Easy. Electroplasma is very hot and very energetic. When it ruptures out of the conduit, The hot energetic plasma not only mechanically fractures the materials around it, but the plasma itself is a form of matter that will, when it’s energy is released and it cools, return to whatever state it would normally be at room temperature.

    Surface ships use deuterium and anti-deuterium as fuel, deuterium is liquid at room temperature. Assuming the combined plasma is also deuterium, that would mean it is eventually condensing to liquid. So I imagine the interaction between the plasma and some other material would turn the other material into a sort of spongy texture, which is probably dark due to being scorched. Thus, I don’t think that’s rock at all. It is scorched material from around the plasma conduit, that has been melted and integrated with the plasma which then returned to a lower energy state, namely deuterium steam or liquid.


  • The explanation I’ve always had- I think this was from some official source but I could have just made it up.

    Starfleet ships use EPS (Electro-Plasma System) to route power around the ship in the form of electro-plasma (a highly energized form of plasma). The warp core generates a lot of this plasma, which is piped through conduits to various devices around the ship. The EPS system and its related systems generate a lot of treknobabble about ‘scrubbing plasma conduits’ (apparently done from the outside using a field generator tool, but still boring), ‘replacing plasma relays’ (the valves that route plasma around, apparently they go bad frequently); problems like ruptured plasma conduits are dangerous and require immediate repair, etc.

    Because this all works in a grid system, whenever the ship takes damage (especially energetic damage like weapons fire) the EPS conduits can carry energy spikes all over the ship. That’s why as the ship takes damage you see random small explosions and sparks all over the place- something hits or spikes the EPS grid and the shockwave ends up, well, wherever in the grid it ends up.

    Of course many EPS conduits go to bridge terminals, especially as those terminals may have direct connections to the ship systems in question.


    Of course in reality this would be seen as a horrible safety risk, and a bridge terminal that could probably run on a car battery shouldn’t have explosive plasma running through it especially when it can explode and harm the operator. In fact one could argue a safe starship should keep all EPS stuff as far away from any essential human-inhabited areas of the ship as possible (especially the bridge).

    One counter to that might be that perhaps the consoles actually play some role in EPS switching, but that seems a bad tradeoff to me.
