Installing task warrior in Ubuntu

Taskwarrior is a command-line todo list manager.

In a world with a lot of virtualized and remotes servers, we need a Post-It alternative ;-)

To install Task Warrior, execute:

sudo add-apt-repository ppa:ultrafredde/ppa
sudo apt-get update
sudo apt-get install task

Quick steps in task:

List tasks
task

Add a task
task add "task to do"

Add a note to a task
task #n annotate "a note"

Done a task
task #n done

There are a lot of commands, you can found them at task warrior wiki


Example:


task
[task next]

sudoer warning message in Red Hat 6.2

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

Els desenvolupadors d'IBM i, incondicionals d'IBM

A l'enquesta el·laborada per Zend el novembre del 2011 a 3.335 desenvolupadors de PHP, que podeu trobar a aquest enllaç:

http://venturebeat.com/2012/01/11/what-developers-will-be-doing-learning-listening-to-in-2012-survey-results/

Developer Pulse (PDF)

Observem que un 3% dels enquestats respon que durant el 2012 emprarà regularment RPG, el llenguatge de programació per excel·lència del sistema IBM i (AS/400).



Coincideix en número amb el percentatge de desenvolupadors que indiquen que el 2012 faran servir la cloud pública d'IBM, la recent IBM Smart Cloud.



Era previsible, els desenvolupadors d'IBM i som poquets, però incodicionals d'IBM :)

Network Upgrade for Ubuntu Servers

1. Ensure you're up to date with latest release:

   sudo apt-get update

   sudo apt-get upgrade

2. Install update-manager-core if it is not already installed:

   sudo apt-get install update-manager-core

3. edit /etc/update-manager/release-upgrades and set Prompt=lts

Note: The minumum contents of /etc/update-manager/release-upgrades should be

[DEFAULT] Prompt=lts

1. Launch the upgrade tool:

   sudo do-release-upgrade

2. Follow the on-screen instructions.

3. At the end of the upgrade process you will be required to restart the server in order to boot into the new kernel. If you do not have access to the console of the system you are upgrading, you may need to edit /boot/grub/menu.lst and change the default boot kernel to the newly installed 10.04 kernel. If this step is not performed your server may attempt to boot into the 8.04 LTS kernel and will hang.
