Pondering version two of "sel"

Posted Yesterday at 03:15 PM by ttk (Unpopular Positions: One Geek's Take)

Some years ago, I wrote a little utility called "sel", short for "select" (to avoid confusion with bash's "select" builtin).

It's more or less SQL's "select" statement for the command line, reading structured data on stdin and writing structured data on stdout, optionally filtering rows (like a structured-data-savvy grep) and creating / removing / reordering columns and changing the format. For instance, it could read CSV in and write tab-delimited...

Devil in the details.

Was trying to get a list of systems up on the network. Pingall.sh would not work at all. It was driving me nuts. So I went to another system and it worked.

$ cat pingall.sh
a=""
for i in {1..254}
do
ping 192.168.1.$i -c1 -w1 -v | grep "icmp_seq=1"
done

$ ./pingall.sh
64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=0.623 ms

NUMA, Linus and the Ancient Conundrum

Non Uniform Memory Architecture is kind of a dry subject for most. Where a bit of code or data sits in processor cache is of little importance to the average user, unless you become interested in things like virtualization (which seeks to maximize the utilization of that cache and slams face first into the issue ) or you're interested in performance testing, in which case squeezing every extra productive cycle out of the hardware becomes a pressing concern. I happen to be interested in both, so...
