  • 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.





  • 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.


  • 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.

    My first computer was an MSX (the model in the vid, not the same one alas) in 1984, it opened up the world of computing for me (hence my username having the 84).

    I have DOS 2.0 running on that thing with FAT16 support, so that means folders and it can (in theory) handle 4GB of data. If I would have told my young self that, my head would have both literally and figuratively exploded.

    Function generators have come down in price so much the past 10 years or so. In the past a good function gen was a very specialized expensive piece of kit. These days you can get a pretty decent unit for not much money at all.

    When I first got this monitor powered up, the vertical deflection was totally collapsed. Turned out two transistors were acting weird. They weren’t broken exactly, but not acting like they should either. Without a function gen I would not have caught that as quickly as I did.






  • Thanks for the clarification, pipes look like copper but might be cast iron.

    Still doesn’t fit with the explanation, aluminum has more resistance than copper, but not that much more. The resistance of cast iron is an order of magnitude higher than aluminum. So it would still be the lowest resistance in the circuit and thus the coolest part.

    And cast iron is pretty good at conducting heat. Not as good as copper or aluminum, but still pretty good. We’ve been using the material to make pans and pots for cooking because of it’s thermal properties. So the heat wouldn’t just stop at the fitting, but continue on at least some ways.

    Moreover it’s physically impossible to get aluminum hot enough to glow like this and still keep it’s shape. It melts at 600 degrees C, well below the point where something gets red hot, let alone yellow like this. If the aluminum were to be this hot, it would be in a puddle and at risk of burning.

    This makes no sense at all.

    Why would only these two specific pipes get hot, so hot to glow, but not the other lines connected to it? And not the fittings around it? It’s all copper, so even if the power itself doesn’t heat them up, why would being connected to an extremely hot pipe heat it up. Since it’s you know copper and being good at transferring heat is what it’s known for.

    And why would the lower resistance part be the part that get hottest? Low resistance means less loss, so those parts would in fact be the coldest of all.

    Plus thin walled copper pipes can’t get so hot they glow without melting or at the very least lose all structural integrity and break.

    And a downed power line with a short to ground would almost immediately turn off. It’s when there isn’t a direct line to ground those things are dangerous. As soon as it shorts, it gets turned off at the source to prevent further damage, fire and not cause issues upstream.

    Either it’s Photoshop or someone has wrapped led lighting around some pipes. Also those aren’t gas pipes.
