No mature, sensible code allows for 10x performance improvement (let alone...). Every time I see a statement like this I take it as a confession.

My personal recommendation for a Tarkovsky's first is his diploma film The Steamroller and the Violin (1960, 46 min, co-written with Andrei Konchalovsky). It was surprisingly watch…

Necessity is the mother of invention? (Голь на выдумки хитра? :( )

I can only repeat my initial statement: > Multi-dimensional RS codes are an easy way to get to an absurdly huge size for real. "Multi-dimensional" may mean 3,4,..,10 dimensions. "A…

I'm not talking about CD-ROMs or immediate availability in any form. How would you encode a petabyte (for a starter) with LDPC/Turbo? Not available right away but accumulated over …

> Larger and larger block sizes are important. LDPC probably is the more practical methodology today, though I admit that I'm ignorant about them. Still cool to see someone try to …

> But I’m here to tell you they got it wrong, and everyone’s been getting it wrong ever since. Students come away underwhelmed and baffled, and go on to become the next generation …

That's why there should be another parameter: you should split the key into N parts so that any M <= N can open the lock. You can increase M adding people you don't trust 100%, say…

It's plain Java (i.e. JVM/JIT), ForkJoinTask based implementation. As in the original implementation, measurement is done around the quickSort() call. One point is actually that th…

Increasing the size of the array 10x (100_000_000) and filling a glaring omission: Go (go1.17.1 darwin/amd64) took 5.591593544s took 5.285948722s took 5.218750076s took 5.239224787…

> Instead of memorizing 20x20 combinations, you limit yourself to a standard 10x10 table (just 25% of all combinations) Actually, 26% (55/210). You say 25% and nobody notices. You …

Please see my example below.

I thought the promise was we'd use Threads for everything and forget to worry about blocking calls. I can't run one OS thread per CPU in my proposed benchmark: I want to run millio…

A friend of mine who had lived in the USA long enough to pick up some local traits had to go back to Russia to renew his expiring documents. One required a fresh photo to be taken.…

For your goods, services... The U.S. of A. is a debt hub. Banks are also debt hubs but on a smaller scale and dependent on their sovereign.
