Hail, hail, fire and snow.
Call the dolphin; we will go.
Far away, for to see,
friendly dolphin, come to me.

No, that'd be Craigslist.

If you're going to go there, might as well go all the way: Bingo Is Not GO. Except that sounds too much like a certain other search engine concern... and LINGO is probably taken... so maybe Ringo Is Not GO?

Good grief. Homophone insanity. We've got Clojure [...] "closures" [...] And now Google jumps in with "Closure"

It's worse than that; there's also Clozure Common Lisp.

The system used in the roguelike Linley's Dungeon Crawl (and its currently-maintained fork, Stone Soup) mostly takes care of that: when you get XP, you also get an equal number skill points; whenever an action practices a skill, some number of points from that skill pool are transferred into the skill, and eventually the skill levels up. If the pool is empty, you don't gain skill. (Also, in the skill screen, skills can be set to not be actively practiced, which greatly reduces the skill points consumed by using them; this is for things like if you're using a given type of weapon but don't plan on specializing in it.)

In practice, there's still some incidence of "victory dancing" --- after a big kill, standing around repeatedly casting some spell to make sure that the points go into some particular magic skill(s) --- but not much, and because the points would have gone into something useful anyway, it's more a question of whether the player actually wants to do that kind of powergaming.

inet6 addr: fe80::***:****:****:****/64 Scope:Link

No need to redact that. It's a link-local, non-routable address []

The lower 64 bits almost certainly contain the interface's MAC address; while it's not as bad as a globally reachable network address, some people still might not want to post it openly on /.

The thing you read somewhere is wrong. There does exist the XGrabServer call, which some window managers use in some cases (mostly older WMs, I suspect), but the documentation strongly recommends using it as little as possible. In no case is anything like that inherent in X11.

Greg Egan's website has a little Java applet to visualise what happens to light around a black hole, dated 2001.

He's got a bunch of other fun stuff there, explaining/"demonstrating" the strange physics (real and theoretical) used in his books and stories.

It'll be deprecated in NetBSD 5.0 (which will be out Real Soon Now; it's well into the release candidate stage), and removed in 6.0; it's already been removed from -current (the CVS HEAD). 5.0 is also the first release to have WAPBL, the new journaling scheme.

zsh tab-completion. $[2**30/1e9] TAB, for example.

(Yes, really.)

The idea is that programs are written in a heavily restricted subset of x86 that can be proven safe, where "safe" here basically boils down to not being able to make system calls or otherwise interact with the world without going through the sandbox library. The program might still be compromised by a third party if it's badly written, but then the attacker won't be able to escape the sandbox either.
