Francois Tigeot has been working on making i915 video support work better; with his latest update, it’s worth trying the Intel-specific driver instead of vesa if you have both the 915 chipset and are running X.
Matthew Dillon changed powerd on DragonFly so that the system is set to max performance if powerd is killed. Now you’ll know why your fans turned on!
It’s a manageable list this week.
- Markov Chains Explained. It’s useful to at least know what Markov chains are, because there are some silly text tricks that can be done, and it’s a good term to use so that you sound smart. (via)
- Rob Pike’s 5 rules of programming. (via)
- Similar: Epigrams in programming. (via)
- snowdrift.coop, a new funding service for open source projects. It’s not launched yet, but it appears to be using a ‘shares’ approach which could be interesting. (via IRC)
- Unix: never go topless.
- On the cruelty of really teaching computing science. Good quote where I found it, too.
- Don’t tell people to use VIM (because) You’re Using It Wrong. Notes how trendy “use Vim!” articles have become. (via)
- The levels of Emacs proficiency. (via)
- The genre-defining video games we forgot. A surprisingly in-depth documentary.
- Eulerian Video Magnification. Heartbeat reading with common cameras. (via a newsletter)
- Sometimes you think of something that should exist, and then you immediately find out it does exist – foot switches for emacs.
- Explaining X11 for the rest of us. (via)
- Awesome-awesomeness. Curated lists of resources for various languages. Two things struck me: one is that Github is being used more like a document repository than a code repository, sometimes, and the other is that this is such a huge list, it almost overwhelms the original purpose of showing what to use next. (via)
Your unrelated comics link of the week: Formicapunk. Boulet’s version of analog technology.
Finally, a much more eventful week. I already noted LibreSSL’s release.
- DiscoverBSD’s news summary for 2014/07/07.
- PC-BSD Digest 31 – there’s now a PC-BSD IRC channel.
- Your server can probably tell you the temperature.
- Future of pf in FreeBSD? Follow the thread. (via)
- DragonFly’s pf alterations discussed for OpenBSD. It wouldn’t be easy without some of the underlying DragonFly architecture, but something for everyone to remember: Henning Brauer is generous with his time and will help people updating pf.
- mfiutil on FreeBSD.
- ia64 processor support is gone from FreeBSD.
- NetBSD now has BIND 9.10.0-P2.
- FreeBSD now has bmake-20140620.
- OpenBSD now has lynx 2.8.8rel2.
- OpenBSD’s relayd now has a new filter language.
- pkgsrc 2014Q2 binaries are out now for several platforms.
- FreeBSD has a new core team.
- More cross-pollination – also from Android?
- OpenBSD-current users will need to update their kernel.
The portable (meaning ready to be brought into other operating systems) version of LibreSSL is out.
If you’re looking to use LDAP on DragonFly, follow this thread (read the first, keep going) as people talk about implementing it, what they installed, etc. I haven’t tried it myself, yet.
The mfi(4) driver has had some data corruption problems on “Thunderbird” series RAID controllers. There’s a newer driver, mrsas(4), that replaces mfi(4) for these controllers and does not have these issues, but switching may mean new drive locations and therefore some work to get booting correctly again. Sascha Wildner has an extensive writeup about what this entails, and how to switch now if you have that hardware (recommended).
I was out sick for a few days this week (Norwalk virus ain’t fun), and so there’s a whole lot of links to follow.
- The History of the Pocket Knife. I link to it because the pictures are pretty, and because a multitool is one of the more useful physical tools you can have. (via)
- Ooh, a new James Mickens video! This is a sort of antidote to the overoptimistic Scott Hanselman video. Computers are a Sadness, I am the Cure. (via)
- Book review: The Art of Unix Programming.
- Computing Across America.
- Again, not DragonFlyBSD.
- Some interesting thoughts and actions on copyright. I bought the bumper sticker the author’s talking about, directly from him.
- Uh oh.
- Multi-process architectures suck. Yet that’s everything we work on these days. (via)
- The March Towards Go. I keep meaning to sit down and actually try a project in Go. (via)
- UNIX Tricks. Some Linuxisms in there, but oh well. (via)
- Vim as Language. Not a bad description. Related by association: I get tired of seeing the little-avatar-plus-name-plus-job-title that gets stuck on so many blog posts. (via)
- An interview with Damien Conway. He’s a very smart and direct person, so the interview is worthwhile. (via)
- Patching the Newton. Some interesting early history. I remember holding a Newton and saying “This should work like a phone.”
- BOOTSTRA.386 – A Bootstrap theme that will entertain you, or maybe give you painful flashbacks. (via multiple places)
Your unrelated link of the week: The 1987 Crystal Light National Aerobic Championship. Imagine there was no Internet access other than what you can telnet to, and nothing on TV other than this. That’s 1987.
Another ‘quiet’ week – lots of commit activity in the other BSDs, but not a lot to point at directly.
- PostgreSQL/FreeBSD performance and scalability on a 40-core machine. (PDF link, via) There’s comparison to DragonFly’s results, mentioned here before. DragonFly’s solution of shared page tables is dismissed because it would require work to do, though I think that’s a symptom of FreeBSD’s more complex locking model rather than complexity of what’s in DragonFly.
- pkgsrc-2014Q2 is out.
- Here’s some notes on the systemd compatibility GSoC/OpenBSD project.
- The FreeBSD ixgbe(4) driver understands RSS, and so does igb(4).
- FreeBSD GENERIC kernels can now use vt(4), the replacements for syscons.
- FreeBSD images can now boot UEFI.
- FreeBSD 9/10 users using the WITH_NEW_XORG option have a temporary binary ports repository to use, to handle the change in the drivers.
The 44th BSDNow episode is out, with an interview of Craig Rodrigues, a tutorial on creating pre-patched OpenBSD ISOs, and the usual discussion of news items, including DragonFly’s recent pf changes.
(I don’t get the pun in the title this time, darnit.)
Matthew Dillon changed the default keep-policy in DragonFly to:
set keep-policy keep state (pickups, sloppy)
This is to match other BSDs (which? I don’t know) and reduce overhead, according to the commit.
A note for everyone: use Hammer default on a very busy filesystem, and you will eat a lot of disk space since all file changes are recorded. (I’ve done this to myself a few times.) Francois Tigeot has a list of tips on how to keep that from happening.
I am pasting the announcement verbatim because NYCBUG is having some hardware issues with their mailing list archive. It’s interesting for both subject matter and because you get to see the inside of about.com. RSVP soon so you can get in!
2014-07-02 – Introduction to Timekeeping, Steven Kreuzer

Notice: RSVP to rsvp at nycbug.org and bring photo ID. RSVPs must be
received by 2 PM, day-of.
Time is a funny thing. You can spend it, save it, waste it and kill it,
but you can’t change it and there is never any more or less of it.
Everyone knows what it is and uses it every day but no one can seem to
In this talk I will provide a brief introduction to time, timekeeping,
and the uses of time information, especially in scientific and technical
