If you’re running 64-bit DragonFly, and you’re on version 2.11, you will want to rebuild with the latest sources. Peter Avalos found a bug with file descriptor passing, and Venkatesh Srinivas fixed it. It will require a quickworld/kernel build – maybe a full buildworld and kernel? I’m not sure. Some pkgsrc packages might need recompilation, too if they also passed file descriptors around.
Sepherosa Ziehau has been making a lot more changes to the msk(4) driver for Marvell Ethernet chipsets. I link to this commit adding support for Yukon Supreme cards, but there’s a great deal of work from him, recently added.
Thanks to Antonio Huete Jimenez, there’s now an explanation in the vkernel(7) man page on how to netboot virtualized DragonFly kernels.
This is a shorter version of a Lazy Reading post, but it’s linking to some extensive writing. Yay for having other people make up for my brevity!
- Here’s part two of the excellently written story of @. Again, interesting because it mentions ASCII, and its unlamented predecessor BCDIC, among other things. Read part 1 if you missed it.
- Stephen Ramsay’s blog – the most recent items are about command line usage. There’s some gems to glean from there, like Jekyll. (via)
- Learn Perl in about 2 hours 30 minutes. The world needs more tutorials like this, or else this.) (also via)
- Obsessive detail over emulation. (via)
- Hey, that’s a good idea for passwords.
Your unrelated link of the day: the comics of Lucy Knisley. (follow the ‘Previous’ links for more)
Well, if you tell it to do so. Matthew Dillon has added a user-settable limit to the amount of memory used during deduplication, so if your Hammer-using system is low on RAM, you can conserve. This is probably most useful if you are running DragonFly in an extremely small VM, or if your name is Venkatesh.
(inside joke; Venkatesh has a crazy old desktop for DragonFly.)
Samuel Greear posted a progress report on his kqueue Summer of Code project. There’s code available now to try it out. It sounds grand, though I can’t identify what effects it will have for the end user.
I’m a bit slow in reporting this, but: BSD Magazine for August is out in free PDF form. The theme article is memory file systems, but there’s all sorts of stuff, including an article from me talking about how I set up bulk builds of pkgsrc.
The August issue of the Open Source Business Resource magazine is out, talking about starting open-source based businesses. It also announces a name change, to “Technology Innovation Management Review”. The reason, according to the editor, is that the original purpose of the magazine was to explain how you could make money creating or using open source software. People seem to have figured that out now…
The question now is how do you make your (probably open source using) business grow. I totally believe that now based on the number of businesses that have sprung up based around open source software; it used to be much harder to find a commercial backer for a project that let you see the source code. Now, it’s practically commonplace. (examples added off the top of my head.)
We went from feast to famine, and now back to feast. grok.v12.su is back up and running, for your source comparison needs. It complements the one at pkgbox64.dragonflybsd.org – plus it still contains source for multiple operating systems.
Note/update: grok.v12.su is having some problems keeping Tomcat running, so your mileage may vary…
EuroBSDcon 2011, which is happening in Maarssen, The Netherlands 2011/10/6 to 2011/10/9, is now open for registration. This is the 10th anniversary!
I’m throwing this in as a late update as I catch up on what happened while I was on the road last week.
- Venkatesh Srinivas is doing The Right Thing and making sure patches get applied to the original software, not just in pkgsrc. (bitcoin, in this case.) Thanks!
- Hey, more reviews (they agree with mine) for Practical Packet Analysis, from other No Starch authors.
- RetroBSD: a tiny version of BSD, based on 2.11BSD and running on MIPS hardware, is available. That was the one that ran on PDP-11 systems, so the small footprint is no surprise. (According to the site) It uses a tenth of the memory, can run its own C compiler, and can fork. Apparently uClinux can’t do any of those things.
BSDTalk 207 is 15 minutes of conversation with Mohammed Farrag about ArabBSD. It’s good to see open source being supported in a part of the world I daresay has been underserved. This is the Internet, so I say that without supporting evidence, of course.
(I have a lot of catching up to do; more posts soon.)
