Hi. I'm a Unix Administrator, mathematics enthusiast, and amateur philosopher. This is where I rant about that which upsets me, laugh about that which amuses me, and jabber about that which holds my interest most: Unix.

Shifting gears

I've hit that point in my career where I cannot hide behind a technical manual all day. I've hit that place where, regardless of where I go from here, I will hit layers 8 and 9 of the OSI model (if you don't know the joke, that's finances and politics, respectively).

Who drives finances and politics? Unlike the other layers, which are driven by physics, electronics, and computer logic, layers 8 and 9 are driven by humans. In my typical quest for understanding (and perhaps for the...

Time Warner IPv6 pains

Posted 04-23-2013 at 01:17 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

I asked TWC about ipv6 a while back, and the tech I got on the phone was as clueless as they come. Oddly, I could see router advertisements with link-local address (modem playing games, or so I thought), so I fired up rtsol and cried as it failed repeatedly.

A bit later, I noticed that with the kids competing for bandwidth and my wife gaming, we were starting to saturate the 20 Mbps we were getting. I call TWC and upgrade to the 50 Mbps package.

Then something peculiar...

Paging? Swapping? Which is it?

Posted 04-15-2013 at 11:52 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

It's a bit big to be called a "one-liner", but this "script" will give you a short overview of paging levels vs. swapping levels on your machine.

Set T=<seconds> to whatever timeframe you want to test for.

Code:
T=5; ( vmstat -s; sleep $T; vmstat -s ) | awk -v T="$T" -F'[(/)]' '/pages paged in/{ pgpio=pgpin; pgpin=$1 } /pages paged out/{ pgpoo=pgpon; pgpon=$1 } /pages swapped in/{ pgsio=pgsin; pgsin=$1 } /pages swapped out/{ pgsoo=pgson;

Et tu, Brute?

One of my other passions (aside from OpenBSD, Linux, philosophy, math, etc...) is Cichlids. Not just any Cichlid, though...Lake Malawi (Mbuna) Cichlids, in particular.

I currently have a 55 gallon aquarium housing quite a few species of Mbuna. One notable species is Melanochromis Auratus. I currently have four of them, all purchased before the color changes to distinguish the males and females. When one started to turn black and blue, I named him "Brutus". He happily...

s/Linux, the new UNIX/Linux, the ONLY UNIX/g

Ok people...if you write code, do us all a favor:

Write **portable** code.

You are dragging innovation through the muck when you write Linux-specific crap. Please, for the love of all that is open source, keep other platforms in mind. Not only will packagers thank you, but your software will reach a wider audience (No matter how big "n" is, n+1 is still bigger than n).

Thank you.
