This is a very basic pomodoro script I am using to avoid getting in a fixed position for hours at a time: <pre lang="shell"> #!/bin/bash UNIT=5 UNIT_CNT=5 PAUSE=6 notify-send -i clock "Starting interval..." for i in $(seq $UNIT_CNT); do sleep ${UNIT}m let c=$i*$UNIT notify-send -i clock "$c minutes" done (for i in $(seq $PAUSE); do let c=$PAUSE-$i+1; echo -n "Pause ${c}m"; echo -e '\f'; sleep 1m; done; echo -e '\f'; echo "Work";) | sm -
This is a simple script I bound to ‘meta+F7’ to activate a second hdmi display I am using: <pre lang="shell"> INTERNAL=eDP1 EXTERNAL=HDMI2 LOCK=/tmp/${EXTERNAL}.on disper -l | grep $EXTERNAL function on { disper -e -d $INTERNAL,$EXTERNAL -r 1920x1080,1920x1080 touch $LOCK } function off { disper -s -d $INTERNAL -r auto rm -f $LOCK } if [ $? -eq 1 ]; then #there is no EXTERNAL, run single command off elif [ -f $LOCK ]; then off else on fi
I’we used ubuntu since edgy days and migrating from gentoo. Things got better each time, until they started getting worse or until I started to expect not to have to fix and patch each time. So now I don’t feel like giving any impression, just a list of bugs: sound is sometimes not working after reboot. This is due to the fact that the sound card order changes. One needs to add: options snd-hda-intel id=HDMI index=-2 in /etc/modprobe....
The goal is to create an encrypted device which gets automatically unlocked using an usb key. Updated on 20160521 for ubuntu 16.04 which creates a lot of problems. Create the key on the usb drive A good idea is to put the key on the usb drive in such a way it’s not obvious that is a key. Usually on the usb drive there is a 512 bytes MBR (1 sector) and then up to 32 other sectors until the first partition....

I have an old laptop with a broken charger. The laptop works on the charger but it does not charges the battery. This should not be a problem since the battery is broken also. However I’ve noticed the laptop is very slow. After further investigation I noticed that the cpu maxfreq is always equal the the low frequency no matter the governor: cat cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq I installed cpufreq and tried setting the governor to performance, no luck....
There is a cabinet in my workplace which contains 5 Dell laptops. Now there will be a 6th and probably last Dell laptop going to that cabinet since my new laptop is not a Dell anymore. And this is not for lack of trying. And I’ve tried also Acer, Asus, Lenovo, even Toshiba. This was part of the now standard 3 year cycle of laptop renewal: make a list of requirements, search for a few weeks, get mad, search again, compromise, buy a laptop....
When storing your backups on an external drive you occasionally take with you it is a very good idea to encrypt your backups. Here are some personal conclusions after trying 2 different solutions. eCryptFs Advantages (reasons to choose): stacked – can be used on top of another filesystem, even on top of NTFS allocated on the fly – no need to pre-allocate your space, it will be allocated on the fly....
