Link Roundup

The best of the Internet today, according to me:

  • OpenBSD 4.5 comes out May 1st, but is available on their site now. Check out the changelog.
  • For whatever reason, they don’t provide a torrent. (Likely because, unlike Ubuntu, it’s rarely distributed as one ISO.) I’d assume the mirrors are going to be crushed soon. I found this Pirate Bay torrent, a good reminder that not everything there is illegal. I’m downloading it now, but it’s quite lonely.
  • Here’s a decent OpenBSD install guide, thought it’s not 4.5-specific. Although far from impossible to install, OpenBSD was not designed with ease of install in mind. (OpenBSD 4.5′s official install guide is available, too, of course.)
  • I’ve posted about it before, but pfSense is meant to be a spiffy FreeBSD-based firewall and router platform with a good web GUI, for those of you who find OpenBSD really tough to install, or who have a pf.conf with a lengthy QoS section that doesn’t actually work. It’s got a pretty impressive list of features, too.
  • For a complete change of pace, Popular Mechanics has a new post, the Top 50 Important Tools. So pointless and yet so interesting. I’ve got to say, though, that I love my Leatherman, which should really be #51, if not higher.
  • Everyone is a little bit baffled, but Xapbr posts a Thank You for MySQL 5.4 Community. I think the baffling is due to several things: (1) There wasn’t much talk about MySQL 5.4 as a community release, (2) No one’s entirely sure where MySQL 5.2 and 5.3 went, and (3) Xapbr’s post makes reference to how we’re more fortunate than we realize for there being a community release for MySQL 5.4, which a paranoid person such as me takes to mean, “I can’t say it, but Sun/MySQL Corp. almost didn’t release a GPL version of 5.4.” Here’s a summary of what’s new. Based on the legalese disclaimer, I think it’s legal for me to link to it. A very incomplete summary: better performance on multi-core machines, and a Query Optimizer that’s worth a hoot when doing sub-selects. (“SELECT * FROM t1 WHERE id IN (SELECT id FROM t2)” would never, ever use an index, for example, and would often behave even worse than you’d expect.)

To create not a block, but an inline code span, use backticks:

Here is some inline `code`.
