Example: enable history for root user.
Edit ‘bash_profile’:
sudo vi /root/.bash_profile
And add the following two lines:
HISTFILE='/root/.bash_hystory' export HISTFILE
Notes
.bash_profile is executed for login shells (via console, either sitting at the machine, or remotely via ssh).
.bashrc is executed for interactive non-login shells (ie: you’ve already logged into your machine and open a new terminal window inside Gnome or KDE)
This is a small script you can use to place a special bookmark that will let you save current page in your google bookmarks.
No add-ons are required and it really easy to use.
javascript:(function(){var%20a=window,b=document,c=encodeURIComponent,d=a.open('http://www.google.com/bookmarks/mark?op=edit&output=popup&bkmk='+c(b.location)+'&title='+c(b.title),'bkmk_popup','left='+((a.screenX||a.screenLeft)+10)+',top='+((a.screenY||a.screenTop)+10)+',height=420px,width=550px,resizable=1,alwaysRaised=1');a.setTimeout(function(){d.focus()},300)})();
Everytime you need to save a google bookmark just click on the Bookmarks menu, select your special bookmark called “Google Bookmark” and enjoy!
Install ModifyHeaders for Firefox:
https://addons.mozilla.org/en-US/firefox/addon/modify-headers/
Then open config panel and add your custom headers to access the REST service.
A single header has a name and a value, so it’s something like:
Name: X-Gallery-Request-Key Value: b333837c...
Add all the custom headers you need, then press “start”.
Now you can browse your REST url with firefox 
Steps to get a simple shourtcut to enable/disable touchpad on a dell 3750 (it should work also on other laptops):
1. create a custom bash script “toggle-touchpad” (see details here) with this code:
#!/bin/bash # this script queries the status of the ImPS/2 ALPS GlidePoint device # via xinput and disables / enables the device accordingly. #get touchpad id XINPUTNUM=`xinput list 'ImPS/2 ALPS GlidePoint' | sed -n -e's/.*id=\([0-9]\+\).*/\1/p'` TPSTATUS=$(gconftool-2 -g /desktop/gnome/peripherals/touchpad/touchpad_enabled) #if status fails, exit 1 test -z $TPSTATUS && exit 1 if [[ $TPSTATUS == true ]]; then xinput set-int-prop $XINPUTNUM "Device Enabled" 8 0; gconftool-2 --type bool -s /desktop/gnome/peripherals/touchpad/touchpad_enabled false else xinput set-int-prop $XINPUTNUM "Device Enabled" 8 1; gconftool-2 --type bool -s /desktop/gnome/peripherals/touchpad/touchpad_enabled true fi
Thanks to http://ubuntuforums.org/showthread.php?p=11504018 for this script (these guys kick ass)
2. check that the script works (run the script to enable/disable touchpad).
3. create a keyboard shortcut for your script:
- open “System Settings > Keyboard > Shortcuts > Custom Shortcuts”
- click on “+” and type “toggle-touchpad” in the name field, and the path to your script in the command field (should be something like “/home/john/bin/toggle-touchpad” )
- click “Apply”
- click on “Disabled” column and type the shourtcut you’d like to use (something like Ctrl+Alt+0)
4. close and test your new shortcut
When http://pypi.python.org is down you’re not able to install, deploy, create enviroments etc.
This is quite boring!
Anyway, pypi has several mirrors:
Add this line to your buildout.cfg to use one of these mirrors and bypass the (temporary) problem:
[buildout] index = http://d.pypi.python.org/simple
mkdir ~/bin/ gedit ~/bin/myscript chmod +x ~/bin/myscript
gedit ~/.bashrc
Append the following two lines:
PATH=$PATH:~/bin export PATH
Plone4 wants python 2.6, anyway people running python2.7 say it that works so … I’ll use python2.7.
I’m using Linux Mint 11 (Ubuntu 11).
Install python-dev package:
$ sudo apt-get install python2.7-dev
Then install EasyInstall: download the egg from “http://pypi.python.org/pypi/setuptools” and then run it as if it were a shell script:
$ sudo sh setuptools-0.6c11-py2.7.egg
Ok, so let’s use paster to create a Plone4 buildout:
$ paster create -t plone4_buildout
Run bootstrap.py:
$ sudo python bootstrap.py
Ok we’re ready, let’s run buildout:
$ ./bin/buildout
Now to start the application type:
$ bin/instance start
Done!
