  • Most people who are fed up with Microsofts crap simply don’t buy a new computer anymore. They just do everything on an iPad (maybe pro) or similar without Windows. Gamers switch over to consoles, with Nintendo and Steam deck being preferred. Those things may run Linux like the Steam deck or another non Windows OS, but the user won’t notice or care since they don’t interact with it.

    The time of the desktop and to a lesser extent the laptop has come and gone. It’s only for enthusiasts and people at work. At work people probably just use the same couple of apps or even just a browser with a webapp and never really interact with the OS. If it’s even a full computer and not a thin client connecting to a virtual desktop environment. People don’t know or care about OSes. Maybe they’ll bitch about Windows at times, but they bitch about a lot of things at work and they have no influence over any of it.



  • Back when token ring was designed normally networks would use coaxial cables for communication. No matter if it ran ethernet, token ring or something else, everybody would share basically a single cable. The cable would have T connectors inserted to connect a computer and the end of the cable needed something to terminate it. It didn’t need to be a single line, you could have splits and even a star like design, although there were limitations.

    And you are right, any disruption anywhere on the line meant the network would go do. That might be someone removing the termination cap on the end, or simply the line being broken somewhere. However because computers were usually connected using T splitters, it didn’t really matter if the computer was connected or not. But the connection not being terminated properly could be an issue. Especially if there was another cable connected to the T before being connected to the computer.

    Normally in a room the cable would be laid out like a ring although it usually wouldn’t be a closed ring, but instead terminated on one end. This meant each computer would be connected to its direct neighbors, but this wouldn’t be an active thing. It wasn’t like the computer could only transmit to its neighbors and then they needed to pass it on. It was like a shared line, where everyone could transmit and every computer would receive everything transmitted.

    When everything switched over to the regular twisted pair cables we know today, it didn’t really change from a communications point of view. Every computer wasn’t connected to their neighbors but instead to a hub, but just like before anything anyone transmitted could be received by anyone on the network. It wasn’t until much later when things like switches became commonplace and not everyone got all the traffic.

    Well there’s the stuff I personally dislike. Like the Elon cringe skits she does, or the super weird uncanny valley face filter.

    But the biggest issue is she didn’t stay in her realm of expertise. She might know a lot about certain things, but then also talks about other stuff with the same level of authority. No caveats, no this is my opinion, she present it as fact. But the fact is she is really really wrong about a lot of shit. And just mixing and matching shit you know and shit you don’t know is a big no-no in science communication.

    One of the most egregious thins she did was make a video about trans folk and talked about it like it’s a fad or even a disorder. She was not only factually wrong, she was spouting anti-trans propaganda. When called out she kept the video up and didn’t do anything like a follow up, correction or apology. She has some really boomer views about a lot of things and then presents it like it’s fact. Another panned video was the one about neurodivergence (autism) and there are more like that. There are multiple hour+ video essays about how she is wrong in these cases and they are worth a watch imho.

    The annoying thing is, I don’t really know what she actually does know. Because she mixes everything and doesn’t stay within her knowledge base, now everything is suspect. So even the videos about physics where I think she does know what she’s talking about, I can’t trust. And even in physics it seems like she’s very hit or miss, I spoke to somebody at a party once that did his PhD on one of the physics topics she covered in a video. He said she was like 10 years behind the times and was wrong about several key facts. Some of these were just wrong because of simplification, which might be excused given the format, but others were plain wrong. Now I don’t know enough about the subject to make a judgement, but the dude I spoke to seemed to know what he was talking about.

    Science communication is really really hard and it’s a skill not a lot of people have. Look at how big the teams of researchers at for example Kurzgesagt are and even they mess up once in a while. But when they get called out, they go back and delete the video or better yet post a follow up or recently even a replacement video. And they qualify things with sources and caveats, mentioning which parts are fact, consensus, speculation and opinion. They also make it very clear at the beginning of the video what a viewer can expect. That way we can qualify the information and know what in what light to put the information presented. Now I realize Kurzgesagt may be one of the best channels when it comes to short form YouTube video science communication out there and it isn’t fair to hold everyone to that standard. But there needs to be at least some level of due diligence involved imho.

    I’m sure I left out some other stuff, there is a lot to find if you look for honest critique. I’m sure there’s also a lot of unwarranted hate out there, but also a lot of stuff that’s warranted.





  • This thing was in geostationary orbit, that’s a long way away where there is no atmospheric drag. There’s also very little orbital debris there because there is less stuff launched that far out and the orbit is much bigger, so the chances of a collision are vanishly small. Temperatures are an issue, but this thing lived out there for years, so it probably was designed pretty well for that. Same with unexpected movement, any leaks or software errors would have presented way before now.

    Something like this breaking up is very strange. It could be a software patch that went wrong and sent the thing tumbling, but there are usually a couple of safeguards against such a thing. Plus any recently patched satellite is monitored very carefully.

    So either an extreme fuckup or some kind of foul play. This could be a test of a satellite weapon, a deliberate sabotage for some reason or a software patch that went very wrong. It could also just be extremely dumb luck with it hitting some kind of debris or piece of rock, but like I said in geostationary orbit that’s not likely.

    Edit: I just read this thing has had issues early in life, so it might be related to that. So that makes malfunction likely.


  • Yes, I lied to my teacher in preschool in the first week of the first year I went there. I was also only just 3 as I had my birthday in the summer and school normally starts in September where I lived at the time.

    Then I skipped a grade in elementary school, because my reading and math was very good. So that meant for pretty much my entire education I was the youngest in class. Not very tall to begin with, but definitely the smallest and weakest because of my age. I was made fun of a lot because of that and physed was terrible. One time the physed teacher took pity on me and graded me on the girl scale to not give me a terrible grade, you can imagine how that went over with the rest of the class. But it wasn’t that bad really, I did have a lot of friends and all the making fun of me never went too far.

    But suffice to say it wasn’t till uni that I really started to like being in school.



  • When I was 3 years old in preschool we had to get in line for the teacher who would write down our name, age, favorite color, etc. on a little badge so they could get to know all the kids. When I was in line the kids in front of me were like my favorite color is yellow, mine is pink and other happy bright colors. My favorite color was a very dark blue, almost black. As I heard the other kids I was like hmmm is my favorite color weird? Am I the weird kid? Is there something wrong with me? So when I got to the teacher I lied and said my favorite color was yellow. She painted a big yellow dot with felt tip pen on my badge which I wore for the next couple of weeks. I felt terrible for lying about it to the teacher, but didn’t want to say anything either.

    So yeah that’s when I figured out I have anxiety.



  • Well you say that, but near the office park where I used to work there was a gas station that served as the outlet for a local sandwich place. All the sandwiches would get made fresh in the morning and be delivered just in time for lunch. They were awesome, there were lines around the block at lunchtime. They were known throughout the area. The sandwich shop also did deliveries for orders of 50 pieces and up, but the company I worked for only did that a few times a year. Haven’t worked there for over 15 years, but I still remember the taste of those sandwiches.


  • Yeah I’ve had that one happen. Big team, more than a year of work, thousands of hours, over 1500 of my own hours. Internal presentation to the team at the customer end, they loved it and couldn’t wait for actual launch day. We were all so proud and everyone was happy.

    Alas that day never came, the customer went bankrupt due to one of the investors pulling out. Nothing to do with us, just some bean counter did the math and decided they were better off letting the company fold.

    I spoke to one of the people at the customer we had worked with throughout the project. She was devastated it was all for nothing and she lost her job as a result. By the time a new investor came around to pick up the pieces, she had found a new job. Spoke to the former ceo of the customer, he had a new job for a couple of days a week at the company that bought up the remainders. He fought to get the project going again, but the new company is very non IT focused, oldskool. So they vetoed it. I later found out one of the project leads was consulted and he had pretty much killed any chance. I always disliked that dude, but he got a pretty good deal out of it or so I’m told.

    That’s just the way the cookie crumbles sometimes.


  • Wow you didn’t like Planet Zoldath? I loved that game. It reminded me a lot of similar games I’ve played in the 80s. Walking around a lot, puzzling, no focus on speed or combat, just trying to explore an alien ecosphere. I absolutely loved that game, especially the variety in the different (randomly generated) maps and strategies you need to use to solve them. Especially the inclusion of aliens that give hints and trade stuff is really cool I feel.

    Sure the walking is slow and the two slot inventory is annoying, but I feel just like with Barbuta, that was kind of the point of it. The walking speed isn’t that slow and the map is very small. And there are strategies you can use to prevent a lot of the backtracking. The game does have the flaw of it being randomly generated, it can give you terrible (or impossible) maps. But I went and got the cherry for this game, I loved it.




  • On the one side we have a perfectly serviceable candidate, maybe not the best ever, but pretty damned good. On the other side we have a diaper wearing grandpa, with severe cognitive issues who is not running for president but instead to be king/dictator. This second candidate is rude, shits on everything, is a racist piece of shit and a felon to boot. He is running only for the grift and will fuck over anybody and everybody (except for his own daughter who he just wants to fuck).

    AND SOMEHOW AMERICANS BE LIKE HOW CAN I EVER DECIDE 50/50

    This simply cannot be reality


  • For me being impressed with SpaceX is kinda like loving a piece of art even though the creator turned out to be an asshole. Or liking Star Trek, even though Berman was shady af to put it mildly.

    What SpaceX does is very impressive from a technical point of view. Even if the rocket never amounts to anything except this one successful test, it’s still amazing they pulled it off. It tickles my engineer brain. And I think it’s worth to honor all the people that made it happen, despite them having to work for Musk. Combine this with what could be in the future and you can hopefully see why people hail this test flight.

    Now I still have serious doubts about Starship in the moon program. The on orbit refueling seems very sketchy and unproven at this point. Sure they will get two rockets into orbit, mate them up and transfer some fuel, that’s a given at this point. But how much fuel are we talking? And how fast does the turnaround need to be to prevent losing a lot of it? How many ships and how many launches? Will this completely offset the cheaper launch costs due to reusability? It’s a huge unknown and will push back the moon program to well into the 2030s.
