  • In this example all 3 observers are in the same reference frame. That is, each of them are moving at the same speed. This is not what the meme is about. In this example the night from Al would reach you 0.06s after he lit it. Which is expected in Newtonian physics.

    The problem of the speed of light being the same for all observers is when they move at different speeds.

    The scenario is: Alice is inside a train moving at almost the speed of light, and Bob is outside it, looking at the train. Let’s set that light moves at 1m/s (for simplicity) and the wagon Alice is in is 1 meter long.

    Alice is at one end of the wagon, and turns a flashlight on. Alice will see the other side of the wagon illuminated after 2 seconds (since the light has to reach the other end and bounce back). Since the wagon is 1 meter long and the speed of light is 1m/s.

    However, when she turns the flashlight on, Bob is also looking. Let’s say that the train moves at 0.99m/s. In that case, after 1 second the light would have traveled 1 meter, but the wagon (and Alice) has traveled 0.99m, therefore the light is only 0.01m away from Alice.

    To summarize: after 1 second, in Alice’s frame of reference, the light has just touched the other side of the wagon. Meanwhile, in Bob’s reference frame, the light has only moved 0.01m away from Alice.


  • That explains why everyone in anime seems so fucking dumb.

    “In order to kill the guy, we have to shoot him in the head”

    “So you are saying that we have to shoot the guy in the head in order to kill him?”

    Yes you little shit, that’s exactly what he said, with the exact same words. It’s so annoying.



  • Most issues are a maintainers issue. Rarely is the issue in Linux itself. Most of the issues are in userland.

    Yes. All OS have bugs, and yes, we are used to doing workarounds for windows too. But most of the time, that workaround is fishing for a setting in an obscure menu with a Windows7 UI. But it is still a GUI. If you read the labels of the buttons you can navigate the menus to reach the button you want to press.

    I have never ever had to edit the registry to fix an issue. I have maybe edited the registry 10 times in my whole life, most of the time it was to customize beyond what the GUI offers, not to fix a bug. That’s on my PC, I don’t work in IT for a company. Maybe company management requires more extensive use of the registry.

    The whole point of my comment is not that Linux breaks constantly while windows doesn’t. Of course it’s going to break more often, since there is an uncountable different Linux configurations, it’s incredibly more complex than having 2-3 versions of windows to maintain.

    The point is that you can fix most issues on windows with the GUI, while on Linux you have to use the terminal most of the times.

    We also know those windows workarounds because GUIs are way more discoverable than terminal commands.

    GUIs act like trees. If you don’t care about the “personalization” branch of the menus, you just don’t click on it.

    Terminals act like lists. You do ls /usr/bin you’ll just get shown hundreds of binaries. Which are not categorized in any way. Only when you know which binary solves your issue you can read the man and get something that hopefully resembles a tree, with headings of different levels.




  • For AR you need to be recording. If you are recording, it is being sent to Facebook servers. You accepted Facebook’s terms and conditions, not me.

    If you don’t want to be punched, you should advocate for laws that make the glasshole glasses ugly through non-avoidable methods of detecting if the glasses are recording.

    For example by requiring every glass hole glass to have a physical cover that physically covers the view of the camera, and it should be a bright color to easily see if it is covering the camera or not. The contour of the camera should be painted with an equally bright color, contrasting highly with the cover. So you can easily see if the cover is covering it completely.

    A led that turns on when recording is not enough, it’s very easy to remove a led from a device.

    If you want to not use glass hole glasses for evil, you should want it to be mandatory for other people to see if you’re using it for evil or not.




  • That would be true if the GUI worked correctly.

    However, more often than not, some inner thing breaks, which means that the GUI just throws an error screen and tells you “good luck”. So you have to search for that text in Google, and it will send you to an obscure forum where a guy said in 2014 that the solution for that problem is to run some random command in the terminal.

    For example the “app store” GUI for Kubuntu never worked for me. It always stalls at some point or another. Meanwhile, running sudo apt upgrade worked flawlessly. Both operations should be doing the exact same thing under the hood.

    Two times already, a relative that uses Manjaro but has no idea about Linux came to me for help because the “app store GUI” (which is a different one than in KDE) one day stopped working. The issue was to run some random key-relayed command.

    Years later, I found out that apparently the Manjaro maintainers let their certificates expire MORE THAN ONCE. Which has to be fixed manually by the end user apparently. And they apparently didn’t think of adding a notification in the GUI telling you about this. Which is bonkers. Not everyone reads all the news articles relating to their OS.
