There is no user interface in Google's browser Chrome yet to disable the disk cache, or control its size (version 14 appears to have something in the developer tools section).

But it can be done using command line options when starting the browser, and you can configure this globally for Ubuntu.

The following command line flags will use /dev/null ("the sink") as cache dir, and additionally limits it to 1 byte:

--disk-cache-dir=/dev/null --disk-cache-size=1

(I have tried just --disk-cache-size=0 or 1, but it did not appear to work as expected)

On Ubuntu/Debian, you can just add these flags to the CHROMIUM_FLAGS variable in /etc/chromium-browser/default and it will be used every time when starting Chromium.

The motivation to do this comes from me using a local (intercepting) HTTP proxy with its cache on a RAM disk. Therefore I do not want Chromium to store quite the same retrieved files on disk again.
Additionally, this is a SSD, which is not that happy about being written to in general.
Therefore /tmp is a tmpfs mount already, and the same should be the case for temporary browser files.

Offenbar auch ein sehr schönes Album, wo Marek Hemmann mit involviert ist..

Marian - Only Our Hearts To Lose by marekhemmann

Alleine wegen des Tracks `Gemini` lohnt sich der Kauf dieses Albums schon sowas von..

Nachdem ich es (aufgrund dieses Tracks) heruntergeladen habe, merkte ich auch, dass sich noch mehr meiner last.fm loved tracks darunter befinden.

Kurzum Geilomat!

Selbst wenn man dann beim MP3-Download feststellt, dass aktuelle Linux-Versionen von Amazon nicht mehr unterstützt werden (man kann dann die Tracks einzeln herunterladen).

The following script allows you to easily double or halve resources in an OpenVZ container.

You would install this script as "/usr/local/bin/vz-double-resources" and also create a symlink named "vz-half-resources" to it (probably also in /u/l/b).

This then allows you to just call "vz-double-resources 123 shmpages" in case you've been notified that there have been shmpages beancounter failures (resource limit has been hit).
This outputs the command to double the bean counter limit, and allows for easy execution by just forwarding the output to "sh", as in "vz-double-resources 123 shmpages | sh -".

Here's the script (available and maintained as/at Gist):

Code:

This is a script I've been using since quite a while (otherwise it would use zsh instead of bash), and have not looked into after creating it.
I just noticed that it is quite useful in general and therefore wanted to make it public.

The provided puppet definition(s) will allow you to add a PPA repository on a host managed by Puppet, e.g. by means of a class like this:

Code:

I have created this to easily add the Current BOINC releases PPA to one of my hosts, and refactored a previously snippet for this.

Since I could not find anything for this, but questions asked about it, I like to share this. The actual code is available at the Gist linked to by this post.
