John Marino has added support for preinit, init, and fini arrays. DragonFly is the first BSD to do so, apparently. What are they for? I’m not sure. The commit message points to more documentation, but not simple enough for me.
There’s a Hammer 2 branch in the DragonFly git repo now, for the next generation of DragonFly’s native file system. Don’t get too excited; as Matthew Dillon explains, it won’t be operational for months, and features won’t get added until much later this year. It’s neat to see the work happening, though, and there’s a new design document to show what’s coming.
If you were thinking about implementing DNSSEC, Michael Lucas did it himself and wrote down his notes. You can read them and either follow along to implement it yourself, or just spectate. The one disadvantage is that it uses BIND 9.9, and I only see 9.8 and 10 in pkgsrc.
Here’s several things to look at:
Michael Lucas’s “BSD Needs Books” talk from NYCBSDCon 2010, on Youtube. I’ve talked about it before because I saw it in person; it’s a good talk. Ironically, he talks about getting a publisher interested in your book, and he just self-published.
Hubert Feyrer linked to the slides of two pkgsrc talks at FOSDEM; one about bringing pkgsrc to MirBSD, and one about pkgin, which is included in DragonFly.
John Marino has made it possible to build world and kernel on DragonFly using GCC 4.6 in the form of gnat-aux. (We’re currently on GCC version 4.4) Note that version 4.6 isn’t included with DragonFly, so you would need to download and compile
GCC 4.6 a very recent version of lang/gnat-aux, and set CCVER=gcc46 before building world and kernel to try this out.
Update: John Marino points out in comments that you need to set WORLD_CCVER, not CCVER as his original message said.
BSD Magazine for February 2012 is out, and the feature item is BSD Certification.
It’s like early spring here in the northeast US. Which would be fine if it was actually spring. I miss snow.
- An explanation of the classic UNIX hierarchy. (via thesjg on EFNet #dragonflybsd) I’m behind any explanation that uses the phrase “accretion disk” to describe an organization.
- Hipster BSD. If this doesn’t make sense to you, it’s based on this.
- Would you like to have DNSSEC upgrading explained to you?
- Hooray for Unicode! (via)
- What Commons Do We Wish For? I was, briefly, technically, an AOL employee after the Time Warner merger in 2000. I didn’t like the notion of working for a walled garden then, and I think that’s why Facebook and other companies irk me now. Anyway, read that article for a good explanation of why that feeling is important.
Your unrelated link of the week: Top Shelf 2.0. A small comics publisher that has put much of their comics online to read. Their stuff on paper is worth buying too, as I have been doing for a while now.
It’s on, again! Not that there was any doubt. I need to collect potential mentor names before DragonFly can be involved, so you can guess what I’ll say next…
Edward Berger found that using a LG/Hitachi DVD drive kept him from successfully booting a DragonFly install CD. Using other manufacturers worked out fine. What causes the problem? I don’t know, but it’s worth mentioning it out loud in case someone else gets bit by it.
There’s a NetBSD Hackathon going on February 10th through 12th, mostly online. I mention this because it may have some effect on pkgsrc, used by both NetBSD and DragonFly. Hackathons for pkgsrc usually happen separately, but no harm in keeping an eye out for any positive benefits.
I’ve reviewed Michael Lucas’s book here before, so when he offered a chance to read his newest, SSH Mastery, I jumped at the chance. Michael Lucas has published a number of technical books through No Starch Press, and started wondering out loud about self-publishing. This is, I think, his first self-published technical volume.
It’s a very straightforward book. The introduction opens with a promise not to waste space showing how to compile OpenSSH in text. Chapter 2 ends with the sentence, “Now that you understand how SSH encryption works, leave the encryption settings alone.” This stripping-down of the usual tech-book explanations gives it the immediacy of extended documentation on the Internet. Not the multipage how-to articles used as vehicles for advertising, but an in-depth presentation from someone who used OpenSSH to do a number of things, and paid attention while doing it.
It’s a fun read, and there’s a good chance it covers an aspect of SSH that you didn’t know. In my case, it’s the ability to attach a command to a public key used for login. It even covers complex-but-oh-so-useful VPN setups via SSH.
If you’re looking for philosophical reasons to buy it, how about the lack of DRM?
The physical version is not available yet, but the electronic version is available at Amazon (Kindle), Barnes & Noble (Nook), or from Smashwords (every other format ever, including .txt). The Smashwords variety of formats means that you’ll be able to read it on your phone, one way or another; I’d like to see more books that way in the future.
There’s a single day between BSDCan and PGCon, May 13th. That day will be the 2012 Joint Documentation Summit. People from BSD projects and Postgres will get together to discuss documentation tools, projects, and so on. If you are going to either convention, I’d recommend visiting this too. This sort of cross-project pollination leads to good things.
