  • 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.


  • 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.







  • Yeah this is the biggest issue.

    The way most housing gets built where I live it works like this: A company handles the project management, buying the land, getting the permits, hiring the builders, doing the marketing/sales etc. This costs a HUGE amount of money, which they don’t have. So these projects get designed on paper and then sold to investors. These put in a big amount of money, with the expectation of the project making money in the sales of the housing in the end. This means they can often double their entry in a couple of years, which is really good in terms of investments. As the investors want to make as much money as possible, the company designing the housing have incentives to not only make the houses as dense as possible, but also as expensive as possible. Their margins in percent are about the same no matter the house, so a more expensive house makes them more money. This leads to really big expensive homes crammed together in either high rises or plots. It’s really dumb as well since detached homes are worth more, they build homes with like 2 meter between them. The biggest issue is, only rich people can afford these homes. Even though more homes are built, the majority of people looking to buy a home can’t afford these. Homes also get sold to investors again, to rent out as the house itself appreciates in value. These expensive homes also have the effect of driving up property prices in the area, which leads to more expensive houses and higher taxes.

    In the end, it’s only the rich that profit. They get the good investment projects, making them even more rich. They get to buy the expensive new homes to live in. They get to buy the homes to rent out and use as an investment vehicle.

    Some places have made them build cheaper homes as well, if they want to get the permit. But it’s not enough. We need to be building practical affordable homes, but we don’t cause the people putting up the money to build stuff don’t want to.


  • The whole mixing colors is white is kinda misleading.

    Colors only exist inside our mind, they don’t exist in physical reality. We have three receptors for wavelength information in the em spectrum in our eyes. They are S, M and L type and they are sensitive to a different range of wavelengths. The M and L range overlap quite a bit and are sensitive to a wider range of wavelengths. The S is apart on its own and quite focused. The receptors turn that wavelength information into signals our brains can read out. Simply speaking the eyes tell our brain for a given part of our retina we have x amount of S energy, x amount of M energy and x amount of L energy. That’s all the information we get.

    So our brain combines this information and decides what color it’s supposed to be. As a child we learn what the different colors are. So we correlate those energy levels to the colors we are taught. This is highly subjective as each brain and set of eyes is different. Most men for example have less sensitivity to colors compared to most women (exceptions exist, this is generally speaking). Thus men see different energy levels, but still can see colors just fine for the most part. However women are on average able to distinguish between more shades of the same color, because they have more information to work with.

    In the modern era however we found out our brains aren’t very picky and will just guess what color something is. In sunlight there is a broad range of wavelengths, which we associate with white light. However when making white leds we found out you can just output some spikes of light in the correct ranges and our brains will say jup that’s white. You can also output shit outside of the wavelength of our three detectors and we don’t notice or care. This makes cheap energy efficient white leds possible.

    In the early days the peaks were very narrow with not the best wavelengths. We would see this light as white, but it wouldn’t be comfortable. Without saying exactly why, we would experience the light as harsh or get headaches after a while. Modern white leds are very comfortable for our eyes and available in a whole range of whites to suit our needs.

    So while a whole lot of wavelengths combined like the light from the sun is white. A bunch of random spikes is also white. It doesn’t have to be all colors.

    Also because colors only exist in our minds, things like grayscale colors, impossible colors and metallic colors are also a thing. There’s a whole lot more to colors than just em radiation at a certain wavelength.









  • I’m still amazed how money is so important that even an unsubstantial amount can prompt a change in behavior. It isn’t even the money itself, but more the thought of something costing money that prompts the change.

    I first noticed this around covid times. Where I live you have to put money in shopping trollies to get them. When you neatly slot in the trolly where it is supposed to go, you get your money back. It’s only 50 cents, so not a big deal. And because it’s so normal most people have a suitable coin sized keychain. In most cases if you go into the shop and ask, they will give you a branded keychain for free.

    With covid this was deemed a health risk, as people fudging about with the mechanism isn’t very hygienic. Plus the shops were required to clean the carts after every use, and the mechanism was hard to clean. So they disabled the coin mechanism and set out a worker to give people cleaned carts and receive used carts to clean. As restrictions lifted, people had to clean their own carts and as time went on less and less people bothered.

    So in the end the situation was as it had always been, but the coin mechanism was still disabled. In no time we saw American scenes with trollies being left all over the place, abandoned in the middle of parking lots etc. It made me so angry, how can people be so inconsiderate? Covid made me angry about selfish people a lot. At one point I saw someone give their trolly a shove on the parking lot, almost directly into my bicycle. I shouted at him and he just called me a faggot and drove off.

    As soon as all the restrictions lifted almost all places went back to the coin mechanism. These days depending on which shop and which location, some have the coin mechanism disabled again. Not sure why, maybe as a convenience to the customers. Mostly people put them back properly however, even in places where during covid people didn’t. Maybe because the world is more normal, people are less selfish? Not sure.

    My world kinda broke when I realized 50 cents was all that stood between people being decent and people being selfish assholes.


  • But even when someone doesn’t vote, that doesn’t mean they aren’t Maga?

    So if half of voters are Maga and 1/3 of eligible voters actually vote, it’s almost impossible to say something about the population as a whole. We can say about 16% would be the lower limit, but it could be a lot higher. If we take the voters as an unbiased large sample, we could extrapolate and say 50% of the population is actually Maga. But since voters are by definition a biased sample, it’s hard to say what the actual number would be. Especially with humans, that have complex interactions, like a certain persuasion could actually mean someone is less likely to vote. Or the other way around, where wanting to vote makes one persuasion more likely. This makes the whole thing pretty hard.
