Month: May 2010
Yay, acronyms! GSoC student David Shao has an extensive page up describing the state of his work so far.
It’s a holiday weekend, at least in the United States, so I’m posting few things that take time to view.
Murray Stokely mentioned this in a comment, but it’s juicy enough to warrant a post: the BSD Conferences channel on YouTube has all 17 of the recent AsiaBSDCon 2010 presentations, plus a lot more from other conferences.
Phil Foglio, the fellow who drew the original BSD Daemon, has several comics strips, all of which are available for free – Buck Godot (complete), MythAdventures (in progress), What’s New with Phil and Dixie (in progress), and Girl Genius (in progress and in print).
I had a sudden buildup of things to link to. It’s three items, but there’s enough info here to eat a few hours…
- Flash Destroyer: (destroying hardware, not like what Apple’s trying) found via the howling void, which of course has lots of complaints about technical inaccuracy. Still, interesting to contrast this with swapcache usage. The Bus Pirate on that site also sounds interesting.
- Handling multiple SSH keys in your SSH config: talks about one issue that came out of a larger IBM developerWorks UNIX tips article which is part of a larger series. I may have linked to parts of it before; it’s firmly packed with usefulness. Seriously, go read.
- Dru Lavigne linked to this article about the future of software development, and I agree with her: it’s a good prediction of the very near future.
Matthew Dillon’s been running swapcache on an Intel X-25 SSD on a very busy (in terms of disk) machine for some months now. Over a long period, the disk activity will wear down the SSD, but it’s important to see if swapcache makes a significant difference with extended use. Do you have to trade disk life for speedy I/O? He reports the results in a recent email.
YONETANI Tomokazu pointed out something that could be useful in the future: when you start getting drive errors, before you throw it out, try lowering the speed. Maybe it’s a cable problem, if you’re lucky.
I’ve been restraining myself from a Facebook rant (other than deleting my Facebook account), as there’s plenty of people complaining about Facebook out there. This description, however, is as good a reason as anything for why there’s better choices.
That was my best segue ever.
Sevan Janiyan passed along a note: there’s a *BSD meetup at the Barrowboy and Banker pub
by London Bridge, in London, the 27th of May. I’d love to attend, both because it’s BSD and because it’s a pub. That pesky Atlantic gets in the way.
Venkatesh Srinivas has been working on idle page zeroing; his work has been committed, and if enabled, should contribute to a teeny speedup. What’s it do? It gets memory ready for use when the CPU is not otherwise busy, so that less time is needed to allocate that memory. It looks like there’s more work on the way, too.
Have I managed to forget all this time to add Dru Lavigne’s excellent BSD Events Twitter feed to my link list on the Digest? Yes, I did – fixed.
If you have a Hammer filesystem, and you want to roll the entire thing back to a previous snapshot – all files, everywhere – it can be accomplished with one command.
I’ve put a few of the reports from pkgsrc builds on DragonFly out. They’re all using pkgsrc-2010Q1, on i386/DragonFly 2.6, i386/DragonFly 2.7, and x86_64/DragonFly 2.7. The links in the reports go to the errors that caused each package to not build. If you happen to see something that has an easy fix, or that you really need to have working, please submit a fix.
Sorry – temporary power outage from high winds killed shiningsilence.com for about a day. Back now!
Binary packages built for DragonFly 2.6 and 2.7 from the most recent pkgsrc quarterly release, 2010Q1, are now available. The utility pkg_radd will access them, or you can download directly.
Sdävtaker has posted about the pre-call for papers, for BSDday Argentina. Check his post for topic and submission details.
From my email to users@:
- I almost have pkgsrc-2010Q1 builds done for every architecture, so I’ll point the default load location for pkg_radd to them within the next 24 hours.
- Are you still using a DragonFly system older than 2.4 and downloading binaries? If so, tell me.
- A project: enhancing pkg_search and pkg_radd to be able to tell when a package is missing because of license restrictions. Anyone want to try it?
If you use Apache, as many people do, some of the default building choices have changed in pkgsrc. Read Matthias Scheler’s post for details.
The May issue of the Open Source Business Resource is out, and the theme is “Communications Enabled Applications”. Sounds obscure, but it’s about deriving a business advantage from networks. In fact, one article directly relates to one of my biggest current projects at work.
