Slack talk at SLUG
Slides are online, and the talk was videoed, so I imagine that the video will go online one day too.
That’s one way of doing it…
Does anyone else think it's kind of creepy that you need a secret code to submit paper proposals for Microsoft's TechEd conference? Cause I sure do. I guess that explains why there aren't many community sessions at TechEd.
Screenshots of entire webpages using Firefox
ScreenGrab 0.8 looks useful for authors wanting to take screen shots of entire webpages, not just the bit that fits on their screen.
Please don’t
A fresh cup mentions the Ruby on Rails exception notifier plugin. The idea is that every time an exception is raised in your code you get an email. This is such a horrible idea that I need to take the time to comment. As someone who spends all his time dealing with large deployments of software, email is the worst way of reporting errors I can think of. Think about it: Email is unreliable to deliver. It could get queued on the reporting server, a mail router on the network, or on your delivery server. Worse than that, it could get marked as spam, or randomly discarded. Email is expensive. There are two kinds of expense here -- email needs to be written to disk reliably, which means you sync() when you write the mail to a destination or a queue. For some MTAs, this can mean several syncs() per email as the mail moves between queues. There can be more than one of these MTAs on the way to the final delivery target as well. Additionally, storing email at the destination is expensive. Think of the backups, virus scanning, spam scanning, caching on clients and so forth. Email is…
Large inodes = faster samba
Ted T'so just mentioned in his LCA 2007 talk that larger inode sizes improves the speed of Samba 4. This is because you can fit more file attributes in the inode. I can't find a reference to the benchmark results online quickly, but wanted to make a note of this.
Mirror traffic during the last day of LCA 2007
It seems obvious to me that videos of LCA 2007 are good.

Errata: Tweak to homework, new VMWare image
It had to happen. I screwed up the ffmpeg installation in the homework for the tutorial, so the tutorial page now has an errata section which explains the problem. Additionally, if you downloaded the VMWare image before now, you'll need to download a new copy. Sorry for any pain caused.
Wrong timezone batman!
Heh, the LCA2007 planet is running in a timezone offset from Sydney time by one hour. I wonder how many people that will confuse? Oh, and holy crap does it aggregate quickly.
Am I really the first?
I find it a little hard to believe I am the first to use an Intel Core 2 Duo for MythTV stuff, but I can't find anyone else reporting this to the MythTV users list... mythtv@mythtv2:~/Desktop/mythtv-0.20$ ./configure *** WARNING *** Your CPU was not detected properly: uname -m: i686 uname -p: unknown model name: Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm pni monitor ds_cpl vmx est tm2 cx16 xtpr lahf_lm If you are using a recent CVS checkout, please e-mail the above to mythtv-users@mythtv.org With the subject "configure did not detect my cpu"
