A program I was using a lot the other week kept crashing. I eventually
figured out that a delete operation performed by the program was eating up
memory until the Linux kernel killed it. I needed a way of keeping my eye
on how much memory was in use at any give time.
The Linux desktop is very flexible. Where there's a will, there's a way so
to speak. I wanted a thin strip across the top of my screen to show how
much memory was in use. There's a nice command line utility called htop
which displays system processes and memory usage in colour in a terminal. I
could get my startup script to launch a terminal running htop. The startup
script would give an unique name to the window so the window manager could
identify it, remove window decoration, layer it low in the z-plane, and
give it a specific size so only the memory and cpu usage would show.
It was a simple adhoc solution which wasn't particularly satisfying in
practice. Luckily, it could be improved upon using a program developed
specifically for that kind of thing:
Conky. I'd tried it before but
my usage of it never took off.
So in the end, memory usage became something of a minor role. In addition is
hard drive partition usage, equally as useful. A few other bits and pieces,
but nothing too OTT. Then I got carried away and decided I would need to see
kernel messages easily. You know like when I plug in a USB stick or gain
super user privaleges or something bad happens.
Anyway, gotta stop gibbering away about it. I used
a Lua script in Conky to generate
coded by wlourf and modified it to
my needs. There's a big download link below to my configuration. If you
don't know what to do with it you'll have to do your own research.
I'm sat in a chair, I'm a space frog. I've been on a space trip somewhere
and have come back altered. I've lost my human form and am now a humanoid
frog. Bright green with orange patterning. My voice is all croaky. I'm
unconcerned by the change.
I watched Doctor Who earlier. Some kind of genetic thing, bacterial or
fungal in form, shaped like a virus but too large, falling like snow
down onto golden fields of wheat. A flying insect is
attaching one of these things just beneath my lower lip. It can't be lifted
off, barbs fix it firmly through skin, into my flesh.
Off the insect flies. I'm woken by a slamming door. Can't determine if I dreamt it or not.
Footage of a MTB ride around Fowlmead in July'12 mixed in with a screencast
of an Ardour2 session providing the sounds. Composition of audio track
began in December 2012. Xephyr and Xrandr commands were used to display a
rotated Ardour2 while Conky displays system information in the normal
orientation. Edited in Openshot.
Video I made to accompany a digital audio/beat composition/track I also
made. I'm reluctant to call it music but it's more that than unadulterated
noise. The audio composition began in November 2012, was dropped and then
picked up again in December. The video is based on a screencast of my PC
desktop in which the ffplay command is playing a video of myself walking
down an alleyway.
A page detailing new stuff and other random noise.
The journal is a general place for writing about what I am doing,
or for making more official announcements concerning the things I do. It's
also a place where I can write freely about my ideas, or just play with words
