Please retest lzav 2.9 on enwik9-should be better.

Preserving 12-bit resolution is "Pro" HDR. Original Lanczos offers 8-bits at best.

You may check lzav 1.4 out, all-zeros runs should compress twice better.

Ah, yes, I'll recheck the constraints regarding such all-zero data, easy to fix.

by aleksv 3y ago
Speeds depend on data as well. Try Silesia dataset first.

Make sure you are using -O3 compiler option, and are not occasionally compiling into x86_64 code which runs via Rosetta2.

Yes, to some degree, I have problems, but not too severe. The problem is you have to think logically, this puts your mind into "black or white" mode, and you have to find strength in yourself not to apply it to all surrounding lif

I'll say more about this system. As such "opposition", however small it is (no reason to talk about how much energy is lost in system), creates a "paradox" between consuming and generating, the "physics" a

You can only create "bad" code in programming, there's nothing bad in programming I know of. Ah, don't forget that as per GitHub statistics, programmers usually have psycho-neurological problems, it's a hard thing f

Which problems do you see in the explanation and graph? It's as easy as it can be, totally nothing fancy, you can create the system out of scrap basically. Note that I'm not an electrical engineer and can't write diagrams. I

For science, Python probably, it gained much tracktion in scientific community in the recent couple of years. But it's only a subset of "programming". C-like languages usually offer to become full-time programmer. In science

Yes, I understand. Python can also be compiled to native code, if its developers decide to go that way. PHP8 is JIT compiled by now. It's more about being "closer to the machine". You can solve much more practical coding prob

Oh yea, to me Lisp looks like Python, that's far from C, and usually it's a "interpreted" language, far from machine. Java and PHP is an example of interpreted language that's close to C, you can easily switch your

Thanks for the lengthy reply. As you can see, you are making a lot of shaky assumptions about physics of the process. That's good, you can't tackle it! The problem is, video is not a proof, you can find a lot of videos of "fr

Yes, that's expected. But it programs you to tackle a problem: energy consumption countered by energy generation. Can you tackle it?

Anything far from C. Anything related to AI-driven mechanism operation: you'll be put in jail if it kills a human. Start your own software business, learn marketing and design, invent a solution to some problem, and become best in that

PRVHASH is a hash function that generates a uniform pseudo-random number sequence derived from the message. PRVHASH is conceptually similar (in the sense of using a pseudo-random number sequence as a hash) to keccak and RadioGatun schemes,

Basically, every point on a sinewave is a random number.

PRVHASH can be also used as a very efficient general-purpose PRNG with an external entropy source injections (like how the /dev/urandom works on Unix): the 64-bit hash value can be used as a pseudo-random number, spliced into 8 ou

There are 1-5 levels. Level 7 is a marketing trick.

This is excellent! (not in "pervert" sense). "pervee" is "first" in Russian.

PRVHASH is a hash function that generates a pseudo-random number sequence derived from the message. Resulting hashes closely follow normal distribution of bit frequency. PRVHASH is conceptually similar to keccak scheme, but is a completely
