Dropbox KDE integration

by Leave a Comment

After working some time with Dropbox I wrote this little python script to make my work with Dropbox more efficient and faster.

With a right click I can Upload my file to my Dropbox account:

#!/usr/bin/env python

import os, sys
 
PUBDIR = '/home/id/Dropbox/Public/'
USERID = 156881168
 
if len(sys.argv) > 1 and os.path.isfile(sys.argv[1]):
 os.popen('cp -f %s %s' % (sys.argv[1], PUBDIR))
 dest = 'https://dl.getdropbox.com/u/%s/%s' % (USERID, sys.argv[1].split('/')[-1])
 os.popen('kdialog --msgbox "Link was copied to the clipboard:\n%s"' % dest)
 os.system('dbus-send --print-reply --dest=org.kde.klipper \
    /klipper org.kde.klipper.klipper.setClipboardContents string:"%s"' % dest)
else:
 os.popen('kdialog --error "Please choose file!"')

Add a menu entry for right click:

Update:
If you want to make it work only for special users on the system, put dropbox.desktop in your home directory: “~/.kde/share/kde4/services/ServiceMenus”

Upgrade Debian lenny to squeeze

by 1 Comment

Debian Logo

This upgrade from lenny to squeeze is not more complexer then the update from etch to lenny.
If you read everything carefully your server will run after upgrade too:)

Before you go on please read the official Debian release notes:

Recording your session:

1

script -t 2>~/upgrade-squeezestep.time -a ~/upgrade-squeezestep.script

First you should update your running system:

1

aptitude update && aptitude dist-upgrade

Check the package state:

1

dpkg --audit

It will show any packages which have a status of Half-Installed or Failed-Config, and those with any error status.

If you had a kernel upgrade please reboot. After successfully updates replace the sources from lenny to squeeze:

‘Argument list too long’

by Leave a Comment


root@web2:$ rm pe-warn-*.bz2
-bash: /bin/rm: Argument list too long

This peoblem happens when you are trying to delete too many files in a directory at the same time – it seems rm has special limits …

To solve the problem:
Use:

1

find . -name 'pe-warn-*.bz2' | xargs rm

or

1

find . -name "pe-warn-*.bz2" -delete

Each of you looses already some important files like photos or important documents.
After a normal Windows crash it’ s not a problem to get all your data back.
I show you some methods to get your data back.

These two examples are taken directly from the ddrescue info pages.

Example 1: Rescue an ext3 partition in /dev/hda2 to /dev/hdb2

dd_rescue /dev/hda2 /dev/hdb2 -l logfile.txt
e2fsck -v -f /dev/hdb2
mount -t ext3 -o ro /dev/hdb2 /mnt

If you have a damaged hard disk /dev/sda1 and you have an empty space hard disk /dev/sdb1 You can copy data from /dev/sda1 to /dev/sdb1 use the following commnd
