The first thing I do whenever I see a discussion about IPv6 is to search for the jokers who talk about IPv5 or IPv7.

Static web servers I've actually seen spend most of their time in a couple of very hot paths (mostly the kernel's TCP stack). The others I agree with 100%, and also of course if your web server is doing any dynamic page work. Web

It will, but they will be abbreviated (only total amount shown, not the individual stack traces) unless you ask to show them in full.

I have a burned CD with some bad sectors that I'd like to recover (it's not a game, it's a rendered animation from 1999… and unfortunately, it's zipped to save 0.1% or so); this makes me want to go hunting for a couple h

Yup, I have one from AliExpress :-) Only done ~50 splices or so, though, but works really well.

by Sesse__ 10mo ago
Modern fiber splicers are fully automatic, so you don't need to smell :-) The only thing that's still mostly by hand is the cutting (mostly stripping away the various layers of insulation).

That's exactly what it's doing. The tricky part is the “hand off state” part.

The short answer is that it's not. The longer answer is that a lot of people already use Git for Debian version control, and the article expands on how this will be better-integrated in the future. But what goes into the archive (for b

AFAIK the most common design for these kinds of systems is using trigram posting lists with position information, i.e., where in the string does the trigram occur. (It's the extra position information that means that you don't nee

Because it is in addition to your writes, not instead of them. That's what “ahead” points to.

Also due to error correction issues. Flash is notoriously unreliable, so you get bit errors _all the time_ (correcting errors is absolutely routine). And you can make more efficient error-correcting codes if you are using larger blocks. Thi

A write-ahead log isn't a performance tool to batch changes, it's a tool to get durability of random writes. You write your intended changes to the log, fsync it (which means you get a 4k write), then make the actual changes on di

The logic we typically use for repeaters (EDFA, erbium-doped fiber amplifiers) for long-distance lines amplifies but does not clean noise (so across the oceans, you are very much bound by SNR). And you need one of them every 80 km or so in
