The best way to develop GMO technologies is to regulate it after it injures millions of people. And that regulation is... declaring anyone who questions the science a terrorist.

Just a few Gb of ram and the feds can audit your state when their zeroday crashes your machine, what a deel.

No, and yes. Systemd is needed to put linux under the thumbs of glowies. The people defending it are paid by your tax dollars

Well, they can't be that bad if the FAA will to listen to them. I can recall another transportation company who is able to have legislation passed for their soul benefit.

Reddit?

Yes, this is an extremely trivial problem. Anybody who knows how to program in more than one language is going to find this silly. awk or perl would finish it before jit compilation gets started.

It's really not. We're talking about gigahertz CPUs and likely solid state storage that can stream many gb/s.. running through a perl script. There really isn't much that is faster than that.

Why are you using cat at all? Use a pipe. This isn't hard stuff. Don't use <>, feed the file into a scalar or array. it should only take a few seconds to process a billion lines.

Perl is always going to be much faster than Java at tasks like this. Use stdin and chomp() instead of reading each line explicitly.

This is really a small, trivial task for a perl script. Even with a billion lines this is nothing for a modern cpu and perl.

That's strange, you should be able to stream the file right into a tiny perl executable at the same speed as the bottlenecking hardware. The kernel will take care of all the logistics. You're probably trying to do too much explicitly. Just use a pipe. Perl should be done before Jit completes.

Perl would do it quite fast and it has the benefit of accessing posix primitives directly.

I don't understand, it should be pretty easy. A rolling average with BigDecimal would probably be sufficient but a scientific lib might be better for a rolling average or more than a hundred million numbers.

Ha ha that's pretty funny but the article specifically states that there's no regulation around these types of rf emissions and that maybe there should be
