OSBR: now it’s TIM

The Open Source Business Resource, linked here before, has become the Technology Innovation Management Review, or TIM Review.   Conveniently, the editor is named Chris, not Tim, so nobody will get confused.  It’ll still cover open-source software, but it’ll also

“share the spotlight with topics such as managing innovation, technology entrepreneurship, and economic development”

The first relaunched issue will be out in October.

Potential job available

A position opened up for a junior systems administrator at my workplace.  You have to be willing to live near Rochester, NY, administrate a mix of Windows and unixy machines, do desktop support, and network management.  (e.g. everything possible)  The work environment is neat, informal, and somewhat adverse.  I’ll have a job description soon, I hope.

Lazy Reading for 2011/09/25

This week’s Lazy Reading just built itself up quickly; autumn arrives in the northern hemisphere and suddenly a lot more activity starts going on.

There are four ways to deal with system damage: 1) reliability, 2) redundancy, 3) repair, and 4) replacement.

More blogbench benchmarks

Francois Tigeot has done another set of benchmarks using blogbench to test reading and writing under different DragonFly versions, plus some OpenIndiana benchmarks just to mix it up.  Writing performance seems to have drastically improved between DragonFly 2.10 and 2.11.

His post has an attached PDF with, of course, graphs.  This site has previously mentioned other not-really-comparable disk testing performed by Francois.

Lazy Reading for 2011/09/18

I might have a job open at my workplace soon, for a junior admin/support/network role.  (Department is too small for narrowly defined roles…)  I’ll post about it here if it happens.

  • libguestfs, ‘tools for accessing and modifying virtual machine disk images’.  (via)  I can think of a lot of places that could be useful.
  • I did not know this, but FreshBSD tracks DragonFly commits, along with the commit logs of most (all?) other BSDs.
  • Bruce Perens set up a “Covenant” license for the HPCC database (powers Lexis/Nexis) that is actually pretty good at allowing something to be both open source and commerical; the ‘release notes‘ talk about it.
  • I agree with these sentiments on hiring exactly.  If you really like what you do, you don’t just do it at work.  (The author’s followup.)  Putting it in a more positive light, showing work on open source, outside of your workplace, is a great thing to add to your resume.  Never trust the graphic designer with sloppy handwriting.
  • The majority of the 10 most stable web providers out there are running a BSD.  FreeBSD, in this case.  (via, via(why does Twitter make it so hard to link to things?  Cause they don’t want you reading the web – just them.)
  • Usenet, as of 1981, with posts arriving in actual time (-30 years).  (via)  You can even use a NNTP reader to connect.  Similar to but not as colossal as telehack, mentioned here before.
  • DragonFly deployment.
  • I am so proud of myself for coming up with this joke.

Your unrelated comics link of the week: Saturday Morning Breakfast Cereal.  It used to mostly be violent and nonsensical, but recent strips are excellent, like this one or this.

Summer of Code and DragonFly, 2011 wrapup

DragonFly had another good year with Google’s Summer of Code program.  We had 6 slots, and 5 passed projects. (Irinia, if you’re reading this – where did you go?)  This is our 4th year participating in Summer of Code, with I think the highest number of passed projects to date.

Here’s all the finished projects, with links to the original descriptions:

Thanks is also due to the mentors and other that helped out, via IRC and email: Aggelos Economopoulos, Alex Hornung, Joe Talbott, Matthias Schmidt, Michael Neumann, Nathaniel Filardo, Pratyush Kshirsagar, Sascha Wildner, Thomas Nikolajsen, and Venkatesh Srinivas

You can also check the Digest’s “Google Summer of Code” category for progress reports made as the summer went on.  The source code from the projects is available at the DragonFly/SOC 2011 Google Project Page.  In even better news, 2 of the projects have already been partially committed to DragonFly – Brills Peng’s  scheduler work, and Adam Hoka’s device mapper mirror project.



PHP 5.3 update on the way

For reasons unknown to me, there’s enough functional change between PHP 5.2 and PHP 5.3 that it affected a lot of PHP-based programs.  For that reason, PHP 5 in pkgsrc defaults to the 5.2 version.  However, it’s going to be 5.3 for the next stable quarterly release of pkgsrc.  In theory, all PHP5-dependent programs are ready to handle that now.  Note that PHP 5.3 is already in pkgsrc; it just wasn’t the default.  If you were using the php53 package, it may require some manual fiddling at your next upgrade of pkgsrc packages.

Old ISA drivers and what to do about them

Some ISA devices have been removed from DragonFly.  That probably affects approximately 0% of everyone, cause they’re old devices, but a few of them are were in the GENERIC kernel configs, so you’ll get an error for an unrecognized option when you next rebuild your kernel using a GENERIC-based config, based on an older version of GENERIC.  The description of which drivers went is quite sensibly placed in UPDATING.
