Reflinks are basically CoW hardlinks — supported on Linux by btrfs, XFS, and I've seen some effort to bring it to ZFS. DragonFlyBSD's HAMMER filesystem supports on-demand/scheduled dedup using the hammer(8) command, with conf

Its main benefit is it's memory-hard in addition to time-hard. You're not just repeating a hash function across a few dozen bytes a few thousand times, you're doing it over tens or hundreds of MB, thus making it much harder

This is why I made https://github.com/Freaky/zfsnapr Instead of working out how to teach my backup tools about snapshots, I just mount them in a subtree and use that as a chroot env.

XKCD estimated 11 bits per "common word", corresponding to a dictionary of ~2000. But that's assuming even distribution across that dictionary, which isn't a reasonable thing to expect a human to do themselves. Diceware

A great deal of the benefit of Option comes from where it isn't used - you know most things can't be null and simply don't have to think about the possibility. unwrap() bugs are annoying, yes, but at the end of the day they&#

No, the benefit of the GMMK Pro is supposed to be build quality. There are plenty of cheap hot-swap boards about. I'm using a Hexgears K705A - it cost me £60, with BOX White switches and cheap double-shot ABS keycaps. That's les

Nothing so fancy. Each worker thread runs in a loop executing a queue of jobs. On every iteration it sets an atomic progress flag to true. The runtime in which it's contained polls its workers every 1-10ms, atomically swapping in fals

It's beaten by half a dozen sync Ruby implementations, which should be a pretty good hint that something else is going on. Lack of HTTP keep-alive is probably the most obvious thing holding it back.

by Freaky 6y ago
Probably the lack of HTTP keep-alive support - it's explicitly disabled due to bugs in the older HTTP library the stable version uses (seen as a large number of errors in previous rankings), so each request needs a new TCP connection.

No. The problem is that to git, a branch is just a reference to the commit currently at the tip of that branch - the rest of the commit graph is completely anonymous sans its position in that graph. Where in SVN it's implicit in the p

As the maintainer of FreshBSD.org, git gives me headaches regarding what to do with branch naming. SVN and even CVS include branch information on each commit, but git couldn't care less - it's up to you to infer it by unspecified

... and it's useful how? It obscures the assignment at the end of an arbitrarily long statement instead of giving the value a name right up front. It feels a bit like a new method definition syntax that allows you to put the name afte

Yes, to highlight that this "horrible rigmarole" and "irritation" you describe is entirely on the basis of there being a Perl script involved. Something I suspect the majority would overlook without even really noticing
