The GUADEC folks keep harassing me for a photo and a bio and a urine sample. It is a neverending tirade from them. They just keep wanting more and more but never give anything. Blah, blah, blah! Anyhow, I did not have any self-portraits on hand--who does?--so I had to recruit Joey and my pinata, not coincidently named Lil' Joey, for a quick shoot in the office.
Another list from Tomboy.
First names that I have had: Robert.
Venezuela's Chavez finally figures out to which ideology he subscribes. In the process, he demonstrates that he has no understanding whatsoever of economics. Or of history, for that matter.
Yesterday, I hacked up a kernel patch and corresponding pmap(1) support for per-VMA RSS statistics. Today, I added per-VMA anonymous statistics.
This allows us to see exactly how much of a given mapping is physically in-core (for example, which pages of this 289MB file mapping are we actually using?) and how much of a mapping is anonymous (for example, which of these shared pages did we COW?). We have always had these statistics on a process-wide level, but never per-mapping. Our developers definitely have a need to see a per-VMA break down of total size, RSS, and anonymous versus file-backed pages.
The patch is a bit of a hack and the accounting is pretty naive, but for curiosity in user-space, it works.
$ ./pmap 16449 16449: gvim Start Size RSS Anon Perm Mapping 08048000 2000K 1076K 0K r-xp /usr/X11R6/bin/gvim 0823c000 204K 64K 60K rw-p /usr/X11R6/bin/gvim 0826f000 2552K 260K 260K rw-p [ anon ] ...
Good accounting or not, this definitely highlights how badly we need optimal function reordering, e.g. GROPE.
SUSE users can just grab a kernel package.
List of things that my second ex-wife took when she left me: The oven mitts, all of our fabric starch, the wooden leg we had on on the mantle, my pride.
