  • “Complicated” math is built out of simple math.

    Squared and cubed are just ways of saying the same number multiplied by itself twice(squared) and thrice(cubed).

    The reasons why they are called that is a reference to the most common use of that math, a square has 2 equal dimensions, and a cube has 3. So when someone asks what is the area of a square with side lengths of 5, it would be 5 x 5, or the volume of a cube with the same side length would be 5 x 5 x 5.

    So taking this shorthand 2^3, and converting it into the full “simple math” equation it represents would be: 2 x 2 x 2.

    The other main thing about complicated math is that there is an agreed-upon order in which we write math.

    If you haven’t gotten that far in math class, don’t worry about it yet. The whole point of learning math is that it is best to learn it in the correct order. Generally, anyone struggling with math has accidentally skipped a step along the way of learning it. All the future things you learn are dependent on knowing the previous foundational knowledge.

    So anyway, long story short.

    This is saying: 45 x 45 = 2025 And that the result of 1 x 1 x 1 added to the result of 2 x 2 x 2 added to the result of 3 x 3 x 3 added to the results of 4 x 4 x 4 added to the results of 5 x 5 x 5 added to the results of 6 x 6 x 6 added to the results of 7 x 7 x 7 added to the results of 8 x 8 x 8 added to the results of 9 x 9 x 9 would be 2025.

    And now you can see why they developed shorthand.



  • Yeah, when I first started VR back with my DK2, I could only wear that about 2 hours at a time. Over the years, not sure how much of it was me adapting to it and how much was VR headsets and aftermarket mods getting better, but I can and often do, spend 16 hours a day in VR now.

    VR has replaced almost every screen in my life. I watch TV and movies on it, I play my traditional computer games on it(flat or 3D or fully converted to 3rd or 1st person VR), as well as my native VR games. With recent headsets being able to fully bring the real world back in and blend it with the VR perfectly, I just socialize equally with the people that are actually in the same room as me, as well as people who just -seem- like they are in the same room as me. The only screen it hasn’t replaced yet is my phone, some people and companies had made some inroads into incorporating phone stuff in VR, but that didn’t really take off. And also I still make sure I can see the real TV everyone else can see when hanging out with my family. So I can be involved in the conversation around what we/they are watching. And yes, the Quest 3 can see TV screens clearly in passthrough, previous headsets struggled there. I can even read the closed captioning.

    To me and my family, it just feels normal now, my sister is also pretty much at the same point. I got her to try it a couple years ago when she was upset that certain games she wanted to play from the couch or recliner didn’t look or run well on her Steam Deck. I was like, you have an amazing computer, you could be playing those games at 4k and not have to be looking down at your hands if you just try it in VR like I do. So she did try, and she has never gone back. She uses my Quest pro, I use a Quest 3, I only modded the pro for about 8 hours runtime, since the controllers were only 8 hours anyway. But since she is mostly using it for PC games, she is generally using an xbox controller. So she just plugs the headset into a charger at her seat. Because 8 hours wasn’t enough.

    Ok, well that has veered off topic, sorry.


  • I really hope, and should probably assume, this is a joke post. But I feel like even though it must be, I’m gonna fall for the bait, as the character you have presented yourself as would have missed out on so much. But I’m gonna explain it in what is hopefully a worthwhile read so it’s not a waste.

    The reason a RealD 3D movie is so bright and blurry without the glasses on is that the scenes for both eyes are projected at the canvas. The light from both images is polarized to perpendicular angles with each other. The glasses have different polarization for each eye that only let in the light from the image intended for that eye. So with the glasses on, it will not only be back down to the correct brightness, but will be 3D instead of blurry, as each eye is only seeing one image now. A properly shot image from exactly far enough away from the other eyes view point, so as to seem as though you saw the scene with your own eyes to start with.


  • Yeah, one of the nice things about it was that not only was it proper 3D, but it was a showcase of how 3D could and should be done. If anyone didn’t watch it in 3D in the theaters, the only other option for seeing it as intended is VR now.

    I’m in the camp of people that has watched it and the second one multiple times. Made sure to catch them in theater first, I rarely bother to see movies in theater. But at home I watch them in my VR theater in perfect 3D, the visuals are actually better in my setup(4k raw videofile on Virtual Desktop, tuned to the exact size and distance I want the screen to be), the sound isn’t quite what a theater would do, but mostly cuz I don’t actually like how “big” they go with the sound at theaters. I’d rather it feel like I’m there, than being so over the top. My audio at home doesn’t have to drown out a crowd of people.

    I think the whole experience in VR is better than theater, the movie presents better at a reasonable volume and soundstage.





  • I just grab an app that lets it increment by amounts other than 10%. Not as good, but doesn’t need root. If I gotta change the volume by alot, I drag the bar. Otherwise I just leave the button at 1% increments. Cuz yeah, my volume is like 1% to 5% most of the time, until I need to watch a youtube video, then it’s like 70%… then the next thing I do on my phone after the youtube video renders me temporarily deaf and everyone within a mile glares at me… and I turn my volume back down to 5% or less again.

    Not sure why every single other thing on the phone uses a different standard for volume than video does… just a new loudness war I guess.




  • Yeah, I remember the first time I tried archery in a VR game. I sucked so bad. But I kept going for 10 hours anyway. I still sucked so bad… but then I went to bed and woke up in the morning and it had all sunk in while I slept. I was immediately pretty good at it then, literally over night. But I had to put in the 10 hours of sucking. Hard to do. I have now put about 100 hours into that character and I pretty much never miss a shot within 50 meters.

    Other skills take way longer. Archery in VR limits alot of variables, no draw weight, the arrow knocks to the same place every time, and the string draws to a fixed max pull back distance. So every shot is the same power level and the arrow flies out at exactly the same horizontal and vertical offset. So it’s actually a pretty relatively easy skill to pick up.




  • Hehe, I just left my starter pokemon at the front of my line up for the whole game. He ended up hitting max level, and none of the pokemon behind him ever really got to fight. He was one-shotting with “not very effective” moves. I also didn’t keep any of the buffs or debuffs, just attack moves. Since I was basically only using one Pokémon, he had to have a bunch of attacks cuz they would run out of uses. I wasn’t as young as you would hope for a “tactic” like that to be my solution to the game. But to be fair, it kept working… so was it really wrong?

    I assume it was pokemon blue, mainly cuz I picked blastoise. My level of creativity as a kid means I very likely wouldn’t have picked blastoise if I was playing pokemon red.






  • Yeah, off-by-one errors are the most common error in programming, and when you are off by +1, and then try to bring it down to 0, it rolls over to max value instead. It makes sense, since some things use 0 as 1 and some things use 1 as 1. The programmer usually just has to memorize which is which… so yeah. Not surprising that it is the most common cause of bugs.
