  • Modern world, summed up in one panel. Except Calvin has way more self awareness based on the last frame.

    Modern types are too self-centered to realize that their “get mine” attitude only applies to themselves. If a Hobbs comes and shoves them in the mud, they only see outrage and feel like a victim who needs revenge. Zero clue that Hobbs is doing the same thing they are.












  • I agree with you, but in context.

    Meaning, ask me for my superpower and what I’d do with it, sure!

    But this channel makes really good science-focused content. So to present this video, which essentially requires an all knowing god-like entity, then try and break down the game theory and probabilities, just seems odd and out of their lane a bit.

    The money is the the less interesting bit, the belief in God and outcome is the more interesting one.

    If you believe the god bit and play the game:

    Take box A&B, get $1.001M: you fooled god, there is free will. Or you are the lucky 1% god can’t predict.

    Take box A&B, get $1000: you did not fool god, there is no free will.

    Take box B, get $1M: you did not fool god, there is no free will.

    Take box B, get $0: you fooled god, there is free will. Or you are the lucky 1% god can’t predict.

    If you don’t believe the god bit, then this is just some sort of con man swindle and you are only getting a max $1000 anyway.

    So I sorta view this whole thing as religious philosophy, which is why it feels weird on a science channel.



  • This was a pretty good video, but the supercomputer setup made me kind of meh on it compared to most of the channel’s videos.

    It isn’t really a “problem” in my mind because no such computer can or does exist (one that can predict your decision with 99% accuracy). And they hand wave away what the computer might be doing or collecting to make that decision prior to you even knowing what the problem is going to be. I don’t think you can just hand wave that away.

    So that “hypothetical supercomputer” is more like an “impossible supercomputer” which ruins this as a thought experiment part of this for me. It’s like saying all-knowing sky fairy/god/budda has made a prediction about your decision, what do you decide?

    Well, I’d say I don’t believe in the sky fairy/god/budda and need evidence about the 99% success rate before proceeding.

    Thanks for reading through this. No Nvidia card. it’s AMD Ryzen 7 CPU with integrated Radeon Vega 10 GPU. 20 GB system memory with 2 GB allocated for the video card. I didn’t install anything for graphics, I just let Fedora do its defaults.

    I looked up the codecs to get the specifics. This was the first thing I found when having Firefox + YouTube issues: https://docs.fedoraproject.org/en-US/quick-docs/openh264/

    Installed that and it wasn’t any better. Then had to figure out how to remove it and try the rpmfusion stuff (whatever that is).

    Here’s the output of systemd-analyze critical-chain:

    The time when unit became active or started is printed after the "@" character.
    The time the unit took to start is printed after the "+" character.

    And here’s the output of systemd-analyze plot > plot.svg (had to covert to jpg to allow the upload):



  • I just switched from Win 10 & 11 to Fedora KDE, about 2 weeks ago. Total Linux newbie. Not looking to hack my OS or anything. I’m relatively computer literate, but not at all a programmer. I just want an OS that works and mostly gets out of the way. And obviously doesn’t spam me with ads or steal my data or lock me into a subscription.

    So far: Fedora and Plasma have been wonderful. But…

    • Computer feels slightly slower. I’m surprised by this.

    • Fedora or Mint…“it just works” isn’t exactly true based on my experience. “Most stuff mostly works okay” is more like it.

    • I had a service keep crashing upon boot: xwaylandvideobridge. Trying to read people’s reports and diagnose was frustrating. I ended up removing it (which I had to look up and figure out how to do). Not sure if I broke anything or not, but it seems like things are working.

    • Boot time is definitely slower compared to Win11. Not slow, just slower. Like 35 seconds. I tried to figure this one out using stuff like “systemd-analyze” but that was also annoying / frustrating. Trying to interpret the output and then trying to interpret what the tech people are saying in the forums. Plus my specific output I was getting from those programs didn’t look right or make logical sense (like it was adding up a bunch of processes as 11 seconds, but then saying each of those processes itself took 11 seconds, which I guess is possible if they are running simultaneously, but not sure).

    • Weird stuff with youtube / video codecs. Firefox would glitch/hang/freeze playing youtube, especially if god forbid you try and do something radical like scroll back in a video. I seriously thought my video card was self-immolating. I finally just figured this out after much suffering. I think there was something about cisco h.whatever codecs, which I installed. But those are apparently terrible. Then I followed this not newbie-friendly fix after trying to figure out how to remove the Cisco ones: https://rpmfusion.org/Howto/Multimedia?highlight=(\bCategoryHowto\b). Not sure why this kind of stuff doesn’t work out of the box. Having one of the biggest websites glitch using one of the biggest browsers is…not…great.

    • HP printer: finally, some good news! I have an HP laser printer and had to print some stuff off last night (a PDF and Word doc). Plugged in the printer, it recognized it correctly, I added printer, it added itself smoothly. Then ctrl-p worked flawlessly.


  • Speed of light is a constant. For everyone. Because it’s linked to time, which is part of 3D space.

    Let’s say you are standing still. Shoot a laser straight out in front of you. Measure the speed, you get c, the speed of light.

    Now, start running forward at 10 mph. Shoot the laser again. Measure the speed. You still get c. Not c + 10, but exactly c.

    Run backwards shoot laser out in front of you. Still exactly c.

    Because your personal time/clock has changed by moving so that you end up measuring the speed of light the same.

    Anyone looking at you, regardless of their relative motion to you will also measure your laser at c.

    It’s just how the universe is.

    Also, speed of light isn’t really the best term. More like maximum speed of the universe. Light just happens to travel at that speed because it has no mass. Everything with no mass travels at that speed.
