Graphs for fork profiling


Robert Luciani, one of the Summer of Code students for DragonFly, did some initial testing of the libc_r and libthread_xu libraries, with some graphable results. Unfortunately, there’s some degree of error, but that’s OK – I just like having tests performed and images created.

Faintly found at FLISOL08


‘Sdavtaker’ posted news of a slight DragonFly presence at FLISOL08. Not huge, but interesting since it’s very oriented towards easy Linux installs. I didn’t know the event existed, possibly because it does not appear to have a central website.

Update: Damien posted a descriptive link – in Spanish.

BSD on TV


Murray Stokely has an interesting post up on his blog noting a bunch of interesting BSD-themed tutorials on (mostly) Youtube. His sentiments – and I agree – are that there should be more BSD instruction in video form, not just the various texts we have today. (via)

BSD systems have always been well-documented compared to the open source … well, ‘standard’ isn’t the right word. Branching past text-based media is a good idea, though I suspect part of the barrier is common Flash support.

Linkpile


I’ve been traveling the past few days, so I’m going to do a linkdump to catch up:

OpenBSD has an interesting mergemaster replacement, sysmerge. I’ve never seen a final answer on if DragonFly needs some sort of merging tool or not.

Nominations for the 2008 Open Source Awards are now possible. (Via)

ScummC is a tool for creating ScummVM adventures, another one of those things that people of a certain age look on fondly. (via)

The first issue of BSD Magazine is out, and Dru Lavigne has a list of the contents.

Hackathon for upstream changes


Jeremy C. Reed, on the pkgsrc-users@netbsd.org mailing list, has proposed a ‘upstream’ pkgsrc hackathon. This would be specifically to construct patches to submit to the vendors of given pkgsrc packages, so that the changes would no longer have to be maintained in pkgsrc. This is a good idea; please jump in if you want to help with DragonFly-specific changes, or if you have access to some of those upstream vendors.

Summer of Code applications accepted


We have 7 accepted projects in the Google Summer of Code; the full list is available at the Google site, with links to each proposal.

We’re now in the Community Bonding Period; time for us to get to know each other.  Please welcome your new student codevelopers; we should be hearing a lot from them over the next few months.

Messylaneous: MySQL, searches, Interactive Fiction, more


I have a collection of small things I’ve been meaning to link; here they all are in a post.

Waxy.org has the details about the never-published sequel to the Hitchhiker’s Guide to the Galaxy game (original playable as Java or as Flash), taken from a backup drive circa 1989; readers of a certain age will appreciate the historic Infocom details, and the page includes (for those with Java) a somewhat playable version of the sequel, Milliways. Waxy also had a link to a history of Interactive Fiction, for those who aren’t as familiar, or if you want to know why Infocom is important. It’s not hard to draw a line from these early games to the LucasArts adventure games and other later variations, like my personal favorite.

Seeing this CPAN search trick for the search bar in FireFox reminds me of something linked to by Hubert Feyrer some time ago: a pkgsrc.se search plugin, so that instead of trawling your /usr/pkgsrc via the command line, you can search through the just-as-fast-but-prettier pkgsrc.se pages for package details.

This undeadly.org article highlights an interesting tool called pkg_mgr; it’s designed to work with OpenBSD ports, but it’d be nice (and I assume not too difficult) to have it work with pkgsrc.

Someday, are we going to be nostalgic for the old default-font no-image open source software web pages? Everyone seems to be getting into making it pretty.

Dru Lavigne’s latest blog post has even more links to click; I’ll draw attention to two of them: the prescient 1967 article “The National Data Center and Personal Privacy“, and OpenSourceHowTo.org.

vm_page structure has changed


Matthew Dillon posted a HEADS UP: that the vm_page structure has changed.  This will probably not affect you unless you are working in the kernel.  He didn’t specify in the message, but it’s probably a good idea to do a full buildworld/buildkernel if you’re running bleeding edge code.

Make 2.0 notes now


Matthias Schmidt has set up (in CVS) a page for new items for the 2.0 release of DragonFly.  If you’re committing something big to DragonFly, write it down there.  Consistent use will give us a pre-prepared list for the actual release, which will probably be late summer.

cpdup features and more


Matthew Dillon’s recent parallelization of cpdup brought up some interesting features: it can do third-party transfers, copying data from one remote machine to another, and while not faster than rsync, it’s relatively easy to use. Vincent Stemen followed up with a mention of his ‘rbu’ (Remote Back Up) product, that serves as a wrapper around rsync and simplifies the backup process.

Following up on ‘dolt’


I’m not technically qualified to answer the question Josh Triplett asked in comments on my ‘dolt’ article:

If you want to fix that, feel free to send me a patch, or just tell me that DragonFly uses the same -fPIC -DPIC that Linux and FreeBSD use.

Tell him at/send patch to josh@freedesktop.org, and if you do, thank you for helping.

Open Source development myths


This article, titled “Myths Open Source Developers Tell Ourselves“, dates back to 2003, but is surprisingly accurate. I suspect these myths will become even more prevalent; the number of open source projects out there has been increasing year after year, or at least that’s my impression. (Is there any person or organization that’s trying to track the number?) My favorite myth in the article: “End Users Love Tracking CVS”.

Blogstress


Not necessarily about me, but I read an article about the continuous stress of blogging, in the New York Times.  Entertainingly, the article says:

Blogging has been lucrative for some, but those on the lower rungs of the business can earn as little as $10 a post, and in some cases are paid on a sliding bonus scale that rewards success with a demand for even more work.

$10 a post?  Given that I’ve been doing this for near-free (the Google Ads buy me a sandwich every now and then) for years, that seems like a lot.  Not much to live on, though.

Another potential tool: dolt


Libtool is a very flexible but relatively slow tool used for a lot of software; it can impose a signicant time penalty during compilation. This post to debian-devel@debian.org names a new tool, dolt, which works as a drop-in replacement for libtool can significantly reduce build time. It’s not (yet) supported on DragonFly.  The name comes from “do ltcompile”.  (from Hasso on EFNet #dragonflybsd)

C++ linking gets a ‘gold’ star


Murray Stokely mentioned the new ‘gold‘ linker for GCC in a blog post. It’s going into binutils, and apparently would provide a nice speedup for linking C++ code. This won’t help so much with (most of) a buildworld on DragonFly, but it would definitely help for KDE or other large third-party applications. (via) No, I don’t know why it’s called ‘gold’.

Solving underlying issues


This article, “Rethinking the interface to CPAN“, over at Perl Buzz, describes something there needs to be more of in the open source community.  CPAN, for those who don’t know, is a way to automatically add various libraries to a Perl installation, similar to BSD ports/pkgsrc or Ruby’s gems.

This is the message from the article: provide a solution to a real problem.  I bring this up because a reoccurring frustration people have with pkgsrc is how to upgrade packages.  Now, there’s no lack of ways to upgrade, but none of these solutions are a match for what people want: an upgrade method that works without frequent side effects or extra work.  This is why portupgrade is very popular for FreeBSD, or apt-get for Debian; it generally works as expected.  We need more of the thought process that leads to those solutions, in open source.

I’m not bring this up just to pick on pkgsrc; we need this sort of thinking for the DragonFly BSD website, too.  It (and the other BSD websites) take the role of a library shelf, with information only available by sifting through it until you find what you want.

Compare that to the Firefox website: most people are going to visit there to download Firefox.  A smaller contingent will already have it and want to upgrade it.  There’s a very clear visual path for 90% of the visitors to the site.  Now, go to any of the BSD operating system sites, and say “How do I install a working desktop system, with X and a window manager and so on?”  It’s going to take some digging.
