Strip Mining of Open Source

Two people, one idea. Richard Hillesley from IT PRO also writes about companies who don't give back to the open source community, like Apple.

It makes for an interesting read and I think his article is much better researched than my own I posted here recently. And showing the dangers of some open source licenses he concludes developers should be careful in their choice of open source licenses.

The GPL, he concludes, not only protects from "strip mining" companies, but also (though IMO less well reasoned) from fragmentation and forking of the code.

It seems Hillesley's article is a response to an article by Fleury.

Power Save Script

I wrote a little powersave script that quickly executes a few commands to improve battery life, esp. on notebooks. You can put it in /etc/acpi/battery.d/20-powersave.sh to start automatically when the computer runs on battery.

#!/bin/bash

SUDO=`which sudo`
SU=`which su`
EXEC="$SUDO $SU -c"

echo Activating power saving mode...

# Automatically suspend USB -- How to automatize?
# usbcore.autosuspend=1 to kernel cmdline didnt work
$EXEC "echo 1 > /sys/module/usbcore/parameters/autosuspend"

# Disable CD autodetection by hal
# sudo hal-disable-polling --device /dev/scd0

$EXEC "ethtool -s eth0 wol d"

# reduce disk writes
$EXEC "echo 1500 > /proc/sys/vm/dirty_writeback_centisecs"

# SATA powersaving mode
$EXEC "echo min_power > /sys/class/scsi_host/host0/link_power_management_policy"

# AC97 power saving
$EXEC "echo 1 > /sys/module/snd_ac97_codec/parameters/power_save"

# Intel-HDA power saving
$EXEC "echo 1 > /sys/module/snd_hda_intel/parameters/power_save"

# optimize scheduling for dual-core cpus
$EXEC "echo 1 > /sys/devices/system/cpu/sched_mc_power_savings"

# Remove fixed network adapter, intel watchdog
sudo rmmod iTCO_wdt iTCO_vendor_support tg3

# set minimum frequency
#$EXEC "echo 866664 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq"

sudo killall guidance-power-manager.py

xrandr --output TV --off

for i in /sys/bus/usb/devices/%s/power/autosuspend; do $EXEC "echo 1 > $i"; done

$SUDO iwconfig wlan0 power on

Actually I think a part of the script might be from someone else...
