Happy birthday to my younger daughter.

The Fall of Avalon Hill (1998). The source link comments lead to a lot of neat game material, and a different viewpoint than what’s in this older article.

AMD CPU users, try this

The’Errata 793‘ issue is apparently a bug where an AMD CPU can hang under very specific circumstances. Sepherosa Ziehau has a fix – please try it if you have the appropriate hardware.

Package building statistics

How long does it take to build all 24,000 packages in the DragonFly ports collection? Apparently about 22 hours on a dual Xeon machine (with I think 36 cores) or 48-core Opteron. This is with synth. I used to measure pkgsrc builds in weeks.

LibreSSL now default in DragonFly

DragonFly now has version 2.4.2 of LibreSSL and uses it in base. Ports may still link to OpenSSL, though – it’s still built by default, though make.conf can be configured to prevent that.

NYCBUG Wed Sept 7: Teaching OSs with FreeBSD and DTrace

NYCBUG is meeting tomorrow night, with George Neville-Neil presenting DTrace work used as college-level teaching material, and talking about more places it could be used. Go if you are near New York City, interested in teaching, or you know – BSD. It’s in a different location than the normal monthly meetings.

BSDNow 157: ZFS, The “Universal” File-system

I’m a day late posting this because of travel, but: BSDNow 157 has an interview with Richard Yao about ZFS (on Linux?), and more story links. I found the “NetFlix and Fill” article link interesting – those are BSD appliances they are talking about that eat so much of the Internet’s traffic.

Zeroing does nothing

This makes sense once you think about it: copy-on-write filesystems (like Hammer2 and ZFS and probably others) actually do nothing when “zeroing” out filespace.

DSA keys disabled on DragonFly

DragonFly-master (i.e. 4.7) now disables DSA keys by default. If you are using a DSA key for SSH/SFTP/whatever, you should change it anyway. Otherwise, it won’t work without workarounds after your next 4.7 upgrade, or by the time of the next DragonFly release.

GCC update

GCC has been updated by John Marino from 5.3 to 5.4 in DragonFly – the 5.4 closed bug list on the GCC site is a good way to find out the benefits.

Pulseaudio removed from dports

There’s been multiple reports of pulseaudio causing problems for DragonFly users. It would get pulled in as a dependency, and audio would suddenly stop working. Uninstall, and audio is fine. John Marino has removed it from dports, to prevent that exact problem.
