Main Queue

This object is available since 7.5.3. It permits to specify parameters for the main message queue. Note that only queue-parameters are permitted for this config object. This permits to set the same options like in ruleset and action queues. A special statement is needed for the main queue, because it is a different object and cannot be configured via any other object.

Note that when the main_queue() object is configured, the legacy $MainMsgQ... statements are ignored.

A Simple Example

main_queue(    
    queue.size="100000"      # how many messages (messages, not bytes!) to hold in memory

queue.type="LinkedList" # allocate memory dynamically for the queue. Better for handling spikes

Comprehensions in Python the Jedi way

by Bjørn Friese

Beautiful is better than ugly. Explicit is better than implicit.

-- The Zen of Python

I frequently deal with collections of things in the programs I write. Collections of droids, jedis, planets, lightsabers, starfighters, etc. When programming in Python, these collections of things are usually represented as lists, sets and dictionaries. Oftentimes, what I want to do with collections is to transform them in various ways. Comprehensions is a powerful syntax for doing just that. I use them extensively, and it's one of the things that keep me coming back to Python. Let me show you a few examples of the incredible usefulness of comprehensions.

How to run a GUI application as a different user:

Suppose you are logged into your Linux box as user1 using some X window system already (with GNOME/Unity/..). Now you want to run some gui app as another user, user2.

Run:

1. xhost + - Run as the user1. This enables access to user1's X window system from other users. You should see following output: 'access control disabled, clients can connect from any host'
2. sudo su - user2 - Using your favorite terminal, log-in to second user.
3. export DISPLAY=:0.0 - optional for some apps.

Ubuntu/Debian Offline Repository Creation Gist

When I googled how to create my own offline repository of packages for use in an offline Ubuntu/Debian machine, the results were disheartening and the steps to be taken scattered all over the place.

The files within this gist will allow you to:

• Download specific apt-get packages... with dependencies included!
• Create a Packages.gz file so that you can add the repository folder you create to the target machine's /etc/apt/sources.list file.
