April 7th, 2009 : KDE 4.2.2 for Windows available
The KDE on Windows team today announced the immediate availability of "Cano", (a.k.a KDE 4.2.2), another bugfix and maintenance update of the KDE release. New in this release is an unstable snapshot of K3B, the KDE cd burning application. As a service release, the changelog contains a list of bugfixes and improvements. Note that the changelog is usually incomplete, for a complete list of changes that went into KDE 4.2.2, you can browse the Subversion log. KDE 4.2.2 also ships a more complete set of translations. The binary packages could be installed with the installer by using the version "stable 4.2.2" (or "stable latest"). In case you are upgrading your KDE installation, deselect the skip basic settings checkbox on the first installer page and press next until you are guided to the release settings page where you can choose the required version.

Gearman C Server and Library in Launchpad
by greut
This is a rewrite (in C) of the Perl version found at http://danga.com/gearman/. It includes the both a client/worker library, as well as the server. The server acts as a bridge between workers (clients who can do work) and callers (clients who want work done). You should run several servers (at least two) for both load balancing and high availability.
Another nice background tasks tool.

Reading from a smartphone, the smart way | Monday Note
by night.kame
Why not push the idea a little further? Let’s imagine. I’m a reader of, say, The Guardian, Le Monde or the Norwegian VG. And I want to consume my online paper during my morning commute. My iPhone (or any future similar device) is set to wake up at 7h00 sharp and download my favorite web sites’ latest updates.
Ca s'appelle AvantGo, et on l'utilisait en 2000. Une bonne phrase dans l'article néanmoins :
Anytime/anywhere broadband availability exists only in Google’s imagination.

Musings of an Anonymous Geek » Blog Archive » How Are You Staffing Your Startup?
by karlcow
pas seulement pour la partie technique, mais malheureusement pour la partie commerciale et communicationSome seem to have given almost zero consideration to the fact that their application might become successful, and its availability might become quite critical. They haven’t given much thought to things like backups or disaster recovery. They have no plan for how to deploy their application such that when it comes time to scale, it has some hope of doing so without large amounts of downtime, or huge retooling efforts.

Setting Up Master-Master Replication On Four Nodes With MySQL 5 On Debian Etch | HowtoForge - Linux Howtos and Tutorials
by camel
& 1 other
(via)
This tutorial explains how you can set up MySQL master-master replication on four MySQL nodes (running on Debian Etch). The difference to a two node master-master replication (which is explained here) is that if you have more than two nodes, the replication goes in a circle, i.e., with four nodes, the replication goes from node1 to node2, from node2 to node3, from node3 to node4, and from node4 to node1.
Since version 5, MySQL comes with built-in support for master-master replication, solving the problem that can happen with self-generated keys. In former MySQL versions, the problem with master-master replication was that conflicts arose immediately if node A and node B both inserted an auto-incrementing key on the same table. The advantages of master-master replication over the traditional master-slave replication are that you don't have to modify your applications to make write accesses only to the master, and that it is easier to provide high-availability because if the master fails, you still have the other master.

flipper - Google Code
by camel
& 1 other
Flipper is a tool for managing pairs of MySQL servers replicating to each other (commonly known as master-master replication or dual-master replication). Master-master replication is a great way of ensuring high availability for MySQL databases - it enables one half of the pair to be taken offline for maintenance work while the other half carries on dealing with queries from clients.
Flipper achieves this by moving IP addresses based on a role ("read-only", "writable") between the two nodes in the master pair, to ensure that each role is available.
Flipper is written in perl, and has been designed to be as portable as possible.

Royal Pingdom » Forget about hacking - your servers might get stolen
by kasi77
When it comes to security, there is often a focus on the software side, thwarting hackers and other virtual threats such as viruses and worms. When it comes to uptime and availability, focus often rests on redundant power, clustering, and other similar strategies. We often forget about something that can put a stop to any operation: good, old-fashioned, real-life robbery.
Cool Solutions: Configuring a Xen VM for Live Migration within a Cluster
by camel
By default, migrating a Xen Virtual Machine (VM) resource causes it to shutdown on the current node and restart on the new one. Once you configure a Xen VM within the High Availability Storage Infrastructure (HASI), how do you configure the Xen VM resource to live migrate among the cluster nodes?

Live Application Mobility in AIX 6.1
by BlueVoodoo
Live Application Mobility is an important component of workload partitioning and provides for increased availability for workload partitions (WPARs). Simply put, it allows you to move WPARs from one logical partition (LPAR) to another while the WPARs are up and running. This article explores how and when to use Live Application Mobility and how to configure a system and its applications to run it.
How To Set Up A Loadbalanced High-Availability Apache Cluster Based On Ubuntu 8.04 LTS | HowtoForge - Linux Howtos and Tutorials
by camel
This tutorial shows how to set up a two-node Apache web server cluster that provides high-availability. In front of the Apache cluster we create a load balancer that splits up incoming requests between the two Apache nodes. Because we do not want the load balancer to become another "Single Point Of Failure", we must provide high-availability for the load balancer, too. Therefore our load balancer will in fact consist out of two load balancer nodes that monitor each other using heartbeat, and if one load balancer fails, the other takes over silently.
