Today I got a couple of REALLY good phishing emails. I was ready to call Amazon and report fraud on my account, and then I hovered over a link and realized it was a phishing email. Watch out for this crap.

Migrating to new server
I’ve just updated the DNS entries for VirtuallyShocking.com to point to the new web server. Everything seems to be working, but let me know if you see something amiss.
Getting a Linux Kernel changelog using git
I am setting up my new webserver (which, incidentally, this post is being written on), and had some trouble with the version of the Linux kernel I was using. I wanted to see whether my problem had been fixed between my kernel version and the current one, but couldn’t find an easy way to do that. User Octayn in ##linux on freenode IRC suggested I use git with tags. A little googling suppiled the right command-line magic.
First, I cloned the linux-stable git:
git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
Then, after changing into the linux-stable directory, I checked the tag names available:
git tag -l | less
That showed me the formatting of the tags, namely v
git log --decorate v3.0.9..v3.0.32
I did find some commits that might have fixed my problem. I upgraded and so far, so good. Only time will tell.
This is here as much for my own reference as it is for yours, but I hope it helps you!
delayacct and iotop in Ubuntu 10.04 Lucid Lynx
I was trying to use iotop yesterday on my workstation and it was complaining that “CONFIG_TASK_DELAY_ACCT” was not enabled in the kernel. “OK,” I thought, “I can rebuild the kernel, no problem.” So I went to rebuild the kernel and discovered that CONFIG_TASK_DELAY_ACCT was already enabled along with the associated config options needed for iotop, so I was confused.
After a little spelunking of old mailing list entries (which I am trying to spare you with this post, dear reader), I discovered that the Ubuntu folks flipped around how the “nodelayacct” kernel boot parameter works for various arcane reasons. Here’s the short version of how to enable it.
1) Edit /etc/default/grub, adding “delayacct” as an option to the GRUB_CMDLINE_LINUX_DEFAULT entry. If you hadn’t already modified that line, it would go from
GRUB_CMDLINE_LINUX_DEFAULT=""
to
GRUB_CMDLINE_LINUX_DEFAULT="delayacct"
2) Run “sudo update-grub”
3) Reboot, and you should be good to go
