Geoff Speicher wrote a very nice transcript of the recent BSDTalk interview featuring Matthew Dillon.
Matthew Dillon has gone into some detail on his thoughts on what a clustering filesystem needs.
Via waxy.org, a textfiles blog entry that describes the structure and events that happen to online communities. Some of it can be thought to apply to DragonFly or other BSDs.
Preview, the version of DragonFly inbetween released code and bleeding edge, has been slipped forward.
If you’re following the released version of DragonFly, the ‘slip’ tag (check your cvsup config file) is the most conservative possible way to update. Speaking of which, a 1.8.1 release is due soon.
UnixReview has several new articles up: “Sprints Important in Open-Source World“,
a certification article: “Examining the Novell Certified Linux Engineer 10 Certification“, and
a book review of “WarDriving and Wireless Pen Testing“
AsiaBSDCon 2007 is March 8th through 11th in Tokyo this year, and the schedule is now available.
It’s very easy to debug a virtual kernel, using gdb, with one caveat/fix.
‘timofonic’ linked to Luigi Rizzo’s work on emulating Linux for the purpose of running Linux-specific device drivers, kind of like Project Evil.
It’s not possible yet, but Matthew Dillon outlined the steps needed to get checkpointing and virtual kernels working together – you could start a kernel, and ‘freeze’ its state – even sending the resultant file to someone to restart and debug.
DragonFly picks up a passing mention in this blog post of someone fighting with pkgsrc on Linux. DragonFly 1.8 itself get tried by this developer, but rejected because KDM won’t work.
Jonathan Weeks noticed this thread about DragonFly’s 1.8 release on OSNews, with much ensuing discussion. (it’s somewhat partisan, so don’t put too much work into reading it.)
Matthew Dillon mentioned that he was trying to decide on what filesystem to use that would help with clustering. The general consensus is “ZFS“, but other filesystems entered the conversation, like LFS (still working on NetBSD) and Plan 9. Also: an explanation of filesystem snapshots.
Matthew Dillon has a rather lengthy writeup of the needs of a filesystem in a clustered latent environment. (i.e. DragonFly’s goal)
This wasn’t on DragonFly, but it can apply: a BSDNexus post detailed the benchmark differences between Win4BSD, VMWare, and native Windows.
Found on the web: WarpBSD, a “project to incorporate OS/2 support into FreeBSD”, though it sounds like the vkernel now makes DragonFly a better choice.
UnixReview.com has 2 new articles up: “Parsing Web Form Input in CGI Shell Scripts“, which deals with the crazy notion of shell scripts handling interactive web pages, and “New Year, More Security Challenges“, which covers some U.S. federal law changes for 2007 that require computer data as part of the discovery phase of a lawsuit.
OnLAMP.com has a nice interview of the people behind PC-BSD, and details on their latest release.
Jeremy C. Reed is writing an article about DragonFly’s virtual kernel, and he had some comprehensive questions. Matthew Dillon had some answers which make a good read.
An ongoing conversation about virtual kernels led to a description of just how virtual kernel and real kernel memory usage interacts; they are surprisingly well synchronized.
