Per customer request I am currently working on an Extension for the popular EventList for Joomla that publishes all these Events to a Facebook page (and invite all people who liked that page).
If you are interested in this very plugin, contact me for a quote: patrick.brueckner@paddy-net.com, the more requested this plugin is, the quicker it will become avaliable.
On Ubuntu Linux 12.10 TRIM on filesystem level is not enabled by default (for a good reason!) but also batched discard is not enabled by default.
The German ubuntuusers wiki suggests running a script every day or week. Since I decided that I only wanted this to run if my load is low, because queued TRIM will only be avaliable in SATA 3.1 and running TRIM can block the system.
I decided to run TRIM daily since that would make it run shorter.
So I wrote this little script (Python this time, no other dependencies but the little script mentioned above and a file /var/opt/trim which needs to be existing and non-empty), which will be executed every 3 hours (using cron).
#!/usr/bin/python
import os, time
TRESH = 1.0
RUN_FILE = "/var/opt/trim"
load_1, load_5, load_15 = os.getloadavg()
last_run_file=open(RUN_FILE,'r')
last_run=int(last_run_file.read())
last_run_file.close()
now=int(time.time())
#print last_run
if now - last_run > 86400 and load_5 < TRESH:
run=1
try:
run=os.system('/opt/trim.sh')
last_run_file=open(RUN_FILE,'w')
last_run_file.write(str(now))
last_run_file.close()
except Exception, e:
import traceback
print traceback.format_exc()
Today, as I got my new harddrive (which is a Samsung 830 SSD), I decided to re-install my copy of Ubuntu (for whatever reason). Copying my home folder, some configfiles and so on is an easy task, but what about all these little programs, that were installed with some manual Installer (like QPilot, VMware, …) because they don’t provide a APT-Installer? I do not do any bookkeeping about those, so I wrote a little script, that checks populates a list of files on my root filesystem and checks them, if they belong to some debian package.
It took a while on my old spinning harddrive, probably there is a more efficient way, instead of calling dlocate for every single file.
My little script:
#!/bin/bash
FILELIST=/tmp/findonapt_filelist.lst
FRESHLIST=0
populatelist() {
echo "Creating fileslist"
eval "/usr/bin/find / -xdev -type f > $FILELIST 2>/dev/null"
}
if [ ! -f $FILELIST ]
then
populatelist &
FRESHLIST=1
sleep 5;
fi
exec 0<$FILELIST
value=0
while read LINE
do
if [[ $LINE != *var\/cache* ]]
then
if [ $(dlocate -S $LINE | wc -l) == 0 ]
then
value=`expr $value + 1`;
echo $LINE;
fi
fi
done
if [ $FRESHLIST == 1]
then
wait
fi
echo "****$value Non-APT Files found";
