As others have said, the energy that a supercapacitor can store is practically nothing compared to lipo. And that is by weight, when supercapacitors are less dense then lipo. If you want more power you can just put more batteries in paralle

Having a tablet instead of air-conditioning and radio volume nobs is also a safety risk.

I tried compressing BC7 (from AMD-s Compressonator) using lz4c and it wasn't much. Just re-ran it (with -hc, version 1.9.3(latest now)) and: "Compressed 5592544 bytes into 5413783 bytes ==> 96.80%". 7z with "7z a -mx=

It is used, and most every other compression technique was/is used in video games. I was thinking of using LZ4, but it doesn't really work that great on floating point, and images are already compressed (png, jpg, and even BCn, ca

That is what i said, that it can be optimized away. "exist" is the wrong word, "is useless" would be better. It is like.. you have a spanner in a box labeled "a" and you have a box "b" that has a piec

If 'b' is actually used then the compiler has to put 'a' in memory. Theoretically. He says that b is not changed, and does not "escape" (the scope of the code in question). In that case b is useless, and thus i

Pointers are "just" integers (unsigned integers of a size, that is). Most languages treat them differently (C assigns them a type, and a stride with it), but that is usually on top of them being integers. Pointers "point&quot

Did you ever wonder why some programs work and some don't ? Luck does not have much to do with it. I have some games that were made many versions of glibc ago, and they still work. Why is that ? (that is a rhetorical question)

If you want to keep the amount of dead people to a minimum, then it makes sense to first vaccinate those who are most likely to die. HN-ians like to model stuff, and i get that. To do it properly we need to know how many "young"(a

When you want to squeeze every bit of performance out of a system, you want to avoid doing system calls as much as possible. io_uring lets you check if some i/o is done by just checking a piece of memory, instead of using read, pool, o

You are right. For most programs, these two are more work for not much payoff. Though they are great for some things.

Nice that it works with various deformations, but because of the latency and more shaders i'l skip this. I have still learned some things from this post.

Voting share ? There is no vote unless you work for RH. And even then. An init system is harder then it seems ? You and Jonnax seem to think that unless you made it you have no right to say anything. Have you ever made an init system ? Rese

Concurrency.. the way i understand it, it is about making parts of the program run independent of each other and thus can run at the same time. But you might want to check out someone who knows better, like Rob Pike: https://www.

Hence you will try to keep the conduction losses low relative to switching losses. Yea, 1kHz is nothing for modern transistors. FET, IGBT or bipolar. Not that it's not worth considering them, ofc.

From what i remember when i cared about such things: It's the gate capacitance (and gates resistance) that leads to switching losses. Usually the biggest part of the switching losses is because the transistor is not fully "on&quot

C is a high level language. C is close to how a computer works. Assembly is the next step down, and is not nearly as hard as the internet would lead you to believe. Step down from that; read a book like "Computer Architecture: A Qu
