It’s actually a plastic ribbon with a metallic foil in a zigzag pattern on top of it. It’s extremely cheap and does a pretty good job. It usually sits on top of a metal bar that can deflect a tiny little bit.
You can read all about it here: https://en.wikipedia.org/wiki/Strain_gauge
The main effect is that the resistance depends on the geometry. So as that changes, the resistance changes as well.
That’s because of the way these scales work. They use a material that deforms under stress and when it deforms the resistance changes. By putting current through this material and measuring the voltage drop, it can be mapped to how much stress the material is under and thus how much weight is on the scale.
This is a pretty roundabout way and has a lot of caveats, but it is very cheap. So cheap scales always work this way. That’s why they aren’t super accurate and have deviations depending on things like temperature. Another big downside is any permanent deformation ruins the calibration, giving incorrect results. That’s why you never put more weight on kitchen scales than it says, it will break them.
The issue you are running into is the way it measures. It applies a very specific voltage and current in order to get the result. The lookup table it uses is only valid within a narrow range. When the battery voltage goes outside that range, it can no longer perform the measurement. Even though there’s plenty of juice for things like the little processing chip and the LCD display. They don’t need a lot of power and can do with low voltages. But it can no longer weigh anything so it just errors out with a low battery warning.
People will probably just post a Powershell script on Github to make it update directly from the official servers without paying the extra fee. It’s funny how the most popular activation scripts are on Github, even though Microsoft owns Github and could easily just delete them.
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.
That would depend heavily on how accessible the computer is and how fat your fingers are. And I can tell you, mine are pretty fat.
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.
Sabine Hossenfelder can fuck ALL the way off. She sucks man.
This game is super cool, I love the idea, the concept, the vibe etc. However it is also hard as balls. Be prepared to die often and not really know what to do in order to not die. I’ve started it a couple of times, but even with longer play sessions didn’t get very far.
What do you mean? We just migrated that software to a Windows XP VM running on Windows 7! That was just 15 years ago, it’ll be good for another 15 for sure.
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.
How do you know not all glass is cheese flavored?
Crossposted it! Thanks, I didn’t know that community existed.
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.
Wow that’s awesome man. Glad you added the ‘since childhood’ part, I was feeling a bit old.
I’ve fixed up a lot of CRTs, but this one is kinda special, since it goes so well with the MSX system.
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.
It can’t hurt to give it more cooling capacity. But it probably doesn’t matter much. It will run a a bit warmer with the sticker, but still be well within what the hardware can handle. Since it normally isn’t a performance critical component, it won’t run too hot and cooling it more gives no benefit.
All the same, I kinda hate it when they put a big heatsink on something and then cover it up with stickers. But the size of the heatsink is usually part of the marketing and not an actual design requirement.
Depends what you mean by “use”.
The Americans are the only ones to have used them in terms of destroying enemy assets (and sadly in that case it was used against civilians). But as a deterrent it’s been used by a LOT of countries all around the world and is still being used for that purpose right now.
An argument could be made the Cold War could have been an all out world war if it weren’t for nukes, with the short peace after WW2 be considered just a break and not the end.
I hope nukes won’t be used, but Ukraine is in trouble and if they are backed into a corner and facing destruction who know what they will do. Same could apply to Iran before long, if they have the ability to get nukes somehow, it might be their only hope. Just please let it be as a deterrent and not actual nuclear war.
