FreeBSDNews.net has a nice summary up of video from all (?) the presentations at BSDCan 2013. Of particular interest to DragonFly users: a video about pkg, the tool used for package maintenance in dports. In this presentation, it’s talking about use on FreeBSD, but the future stuff applies to DragonFly too.
Not as wordy this week, but still wordy. And linky!
- Max Headroom and the Strange World of Pseudo-CGI. A discussion of how old fake CGI can look better than modern, real CGI. This is an opinion I’ve had for quite a while, and my children pretty much ignore it every time I bring it up. (via)
- The Colby Walkmac, which predates the Mac Luggable. Linked to because it includes good pictures of what the (external) hardware was like. I find all the old ports interesting, since it’s all USB and the occasional eSATA these days… not that I’m complaining! I’ve never had a good experience with a 9-pin serial port. (via)
- A brief education on escaping characters.
- I get worried when remotely rebooting a server in a different town or even state. In Praise of Celestial Mechanics covers much more stressful circumstances: interplanetary reboots. Does Voyager 1 or 2 have an ‘uptime’ function?
- The equivalent of what you are doing right now, 20 years ago. I personally never got to see this; my experience was MUDs. Speaking of which…
- The Birth of MMOs: World of Warcraft’s debt to MUD. MUD == MMO, Roguelike == Diablo/Torchlight, Doom == almost everything else. There’s a number of game archetypes that haven’t changed in some time. (via)
- Playing with powerlines. I used to work at a company that used these lines for data transfer. It was neat technology, but it sure wasn’t easy to set up. Imagine wiring a city but only being able to use Ethernet hubs. Not switches, hubs. That, combined with undersized ARP caches/MAC tables, made it really difficult.
- OpenVPN on FreeBSD, which will come in handy for at least several readers, I’m sure, as the directions should apply to any BSD.
- Is there anything DNS can’t be used for? Cause now it’s domain-based mail policy publishing. (via ferz on EFNet #dragonflybsd)
- “Have you tried DragonFly?” posts on various forums seem to pop up with some regularity.
- Uses of tmux, explained. A slide show talking about how tmux works. (via)
Unrelated link of the week: I’ve had several deadlines and a mail server with issues this week at work, so this is all I got.
Phoronix has another set of benchmarks that include DragonFly and PC-BSD, along with several Linux distributions. It’s interesting to see, though don’t take them as performance measurements. 7-Zip as a benchmark doesn’t describe much other than the program itself, and the Himeno benchmark results are because of the compiler in use rather than any underlying performance aspect of the operating system – for instance. The DragonFly benchmarks disappear after page 3.
Michael W. Lucas wrote a new edition to his Absolute OpenBSD book, and that second edition was published relatively recently. It’s a hefty book, nearly 500 pages in length, and I’ve needed to write a review for some time now. Not-necessarily-relevant-disclaimer: I contributed the IPv6 haiku/joke at the start of Chapter 12.
If you’re interested in OpenBSD, it’s an obvious purchase. It goes into detail for all aspects of OpenBSD, starting with a very detailed conversation about installation, then disk setup, and so on. This is not going to surprise anyone, of course. Past the initial overview, the book starts with a chapter that talks about nothing else but locating other resources to help learn OpenBSD. It seems a little counter-intuitive to start a book with advice on how to look somewhere else, but it makes sense in light of the topic.
What if you aren’t using OpenBSD, at least not right now? Something I didn’t realize until I had chewed my way through most of the book was that there’s several smaller books hidden inside. The book goes very far into individual utilities. So far, in fact, that it ends up creating mini-guides about the topics within the chapters. (or entire chapters, in the case of pf.)
There’s in fact 2 chapters for pf, initial and advanced. TCP/IP gets close to 30 pages just to itself, and topics like snmpd or chroot get an introductory section that assumes nothing about your prior knowledge. These are technologies you’re using already, no matter which BSD flavor you’re dealing with.
It works as a reference. I’m going to show the aforementioned chapter 11, on TCP/IP, to my coworker who makes a confused face every time I say “link-layer protocol.” I don’t know if he’ll make it from one end to the other, but it’s a lot better than waving a hand in the air and mumbling “You should look that up on the Internet sometime.” There’s enough detail that some of the smaller sections could probably be broken out into individual books, and I daresay that’s what is happening with Lucas’s Mastery series.
It’s comprehensive, it’s readable, and you’ll find something useful in it no matter your experience level. The book is available in printed and eBook form, from the usual online stores linked at Michael W. Lucas’s site, or directly from the publisher. It’s also available through the OpenBSD Project, which then gets a cut towards development.
There’s a new BSDTalk by way of the recently-completed BSDCan 2013 event, and it’s half an hour of talk with Matt Ahrens about ZFS and matters related.
Loïc BLOT posted about his benchmark of several operating systems using KVM and Postgres 9.1. Happily, DragonFly is the fastest, with one exception. Linux/ext4 comes out faster – if you run it with barrier=0, which can be dangerous in a non-battery-backed-up volume.
PC-BSD now has a hardware store, with equipment known to work under PC-BSD. Chances are good that if it works for PC-BSD, it’ll work for other BSDs or could be ported to do so… (via)
The May issue of BSD Magazine is out with a number of pf articles, plus others.
vBSDCon, the newest BSD conference, happening in October and in Virginia, has a new website. (via)
There’s another BSDTalk episode up already, because Will Backman’s at BSDCan 2013 and talking to Scott Long, Alistair Crooks, and David Discher, about NetFlix. Apparently there’s streaming video available now from the convention, and some people’s presentation slides have shown up.
BSDTalk 225 has 12 minutes of conversation with Kris Moore about PC-BSD, recorded at BSDCan 2013, which is going on right now.
Ansible seems to be a configuration management system that’s lighter than puppet or salt. I had a student talking about it in my class tonight. BSD users Hubert Feyrer and Michael W. Lucas have both posted about it recently. Anyone want to repeat their experiences?
I am somewhat entertained by Michael W. Lucas’s most recent blog post about IP Sets. This is mostly because, as he points out, he could use one pf config file across multiple machines and BSDs for network management, but has to fiddle with ipsets to get different Linux machines to match.
For those of us still on IPv4 networks, the BSD-specific OpenGrok site bxr.su should now be available in general, not just on IPv6.
The April 2013 issue of BSD Magazine is all about FreeNAS. I mean, every article is FreeNAS related. If you’re curious about the product, this is the place to start. (The magazine is also now available in ePub format in addition to PDF.)
Does FreeNAS count as another BSD flavor, rather than an appliance? I’m not sure.
I think spring has arrived; everything’s turning green, and a young man’s thoughts turn to computer hardware upgrades. Time to move to 64-bit! Anyway, lots of links this week. These are getting more and more content-filled over time, but I don’t think anyone minds…
- For the Bitcoin enthusasts: ‘…when my wife refuses to bring him cake on our sofa, he calls it a “denial-of-service attack”’ (via)
- Make It So, coverage of computer interfaces from movies. I always thought that was what Enlightenment was trying to achieve: the Interface From The Future. (via several places)
- Same computer interface topic, but from anime movies. It would be nice if this became something people actively worked on, instead of Bitcoin selling and Facebook monetizing. (via)
- Flat icons/monochromatic icons seem to be another microtrend. This is probably because few people do small dimensional icons well. My favorite was always the BeOS set.
- On benchmarks. It says what you should already know, but I like the Phoronix/MD5 benchmarking joke. (via EFNet #dragonflybsd)
- This article titled “The Meme Hustler” draws a finer line than I’ve seen before between “open source” and “free software”. The author, Evgeny Morozov, seems to also have a hate-on for Tim O’Reilly. See some reviews of a recent Morozov book for a counterpoint, of sorts.
- Spacewar championship, 1972, in Rolling Stone. Exactly two years before I was born! At this point, finding things older than me makes me a bit happy. There’s a picture of a Dynabook in there, photographed by Annie Liebowitz. It’s entertaining to read this 40-year-old story and see how well it predicts the future. I’m also sort of amazed it exists, in Rolling Stone. More Spacewar links here.
- Meet the Web’s Operating System: HTTP. “Because HTTP is ultimately the one social contract on the web that, amidst a million other debates over standards, rules, policies, and behavior, we have collectively agreed to trust.” (via)
- Ancient computers in use today. I’ve linked to a story about that IBM 402 before, but the following pages about VAX and Apple ][e systems are new. Well, new to read, certainly not new hardware. (via)
- Yahoo Chat! A Eulogy. The spray of forbidden words is an entertaining acknowledgement message. (via)
- The $12 Gongkai Phone. Bunnie Huang breakdowns are always fun, and he’s describing a strange sort of open source that isn’t through license. (via)
- The FreeBSD Foundation is looking to hit a million dollars donated this year, which seems quite possible given last year’s performance. Donate if you can; their activities help the whole BSD community.
- A Complete History of Breakout. It’s not actually complete, but that’s OK. It includes Steve Jobs being a jerk and Steve Wozniak being very clever, which is their traditional roles. (via)
- Ack 2.0 is out. It’s a very useful utility; I’d like to see more standalone utilities created this way.
- Space Claw, Flickr via BBS. You’ll need telnet. (via)
Your unrelated link of the week: Shady Characters, a typography/history blog I’ve linked to before, has a book out. If you liked those links, you know what to do next.
Ivan Uemlianin expressed a desire to read about the boot process, and how BSD works in general. I made a short list of suggestions.
Peter N. M. Hansteen has a long writeup about using and creating ports on OpenBSD, which is apparently a reprint of an article he wrote for BSD Magazine back in 2008. I don’t remember if I read it, so it’s new to me, in any case. Port and package creation across the BSDs is juuuust close enough that reading about one version will leave you with a good guess about the others.
BSDCan 2013, which is happening in a few weeks, is going to have a “Documentation Lounge“, which is essentially a docs sprint, but with a much more relaxed-sounding name. Anyway, it’s a good thing to contribute to.
Eric Radman sent along a plug for a utility he is working on called entr(1). The desciption is “Run arbitrary commands when files change.” The site for it has several nifty examples – run make when *.c files change, or convert Markdown files to HTML as soon as they are modified. The really nice thing about it is that it’s perfectly BSD-friendly, and uses kqueue, but will also work on Linux. This beats the “This runs on the one flavor of Linux I use, in one particular shell!” approach I’ve seen from some other developers. See the reddit discussion of it for comparisons to inotify. No, it’s not in pkgsrc/ports yet.
Update: And thanks to Thomas Klausner, it’s in pkgsrc as sysutils/entr, and in ports as sysutils/entr thanks to Eitan Adler. You have no reason not to try it now.
