MySQL Cluster is used to provide high-availability, high-redundancy for the distributed computing environment. You might know that beginning with MySQL 5.1.24, support for the NDBCLUSTER storage engine was removed from the standard MySQL server binaries built by MySQL. Therefore, here I’m using MySQL Cluster edition instead of MySQL Community edition. I’m using 3 servers (1 Management and 2 data) to setup cluster in CentOS 5.4 Linux box. The steps mentioned here can be used for quickly deploying a cluster and worked out for me but no guarantee that this will work for you, So its always advisable to go through official MySQL guide as well for production environment. In case you are also riding on cloud computing wave, I’ve already blogged way to setup MySQL cluster in Amazon EC2 environment.

Without an operating system – Mac OS X, say, or Windows XP – a computer is just a dumb box of chips, and even the most exciting application will have no environment in which to run. And, it's easy to forget that you have a choice of which OS you run. In fact, as a Mac user, you're uniquely positioned because an Intel Mac is the only computer in the world that can legally run all three major operating systems, Mac OS, Windows and Linux. Indeed, you can, if you like, load all three on the same computer and pick which one you want to load when you switch your Mac on.

Hundreds of mobile developers and enthusiasts converged this weekend at the McCormick Tribune building on the Illinois Institute of Technology campus in Chicago to hear from other developers and industry thought-leaders about the current state of construction, deployment, and management of mobile applications.

In developed countries, healthcare workers represent a significant proportion of the working population. For example, in the United Kingdom, more than 1 million people work for the National Health Service, a publicly funded healthcare system. Medical software therefore has a huge market to tap. Whatever stage of a country's economic development, health care is one of the most important elements in society.

LXer Feature: 07-Mar-2010

In the LXWR this week we have Munich showing off its migration to Linux at CeBIT, Ubuntu opens up a music store, a nice review of OpenShot, Jeff Hoogland 'mints' his girlfriends laptop, the three giants of Linux and a LXer feature about contributing upstream..enjoy!

An overburdened CPU is another obvious place to look for performance problems on your system. Similarly io can be a bottleneck in proper system performance. You can watch various parameters if you install sysstat package. On Ubuntu you can install with $ sudo apt-get install sysstat

This article shows how you can build your own video community using lighttpd with its mod_flv_streaming module (for streaming .flv videos, the format used by most major video communities such as YouTube) and its mod_secdownload module (for preventing hotlinking of the videos) on Debian Lenny. I will use FlowPlayer as the video player, a free Flash video player with support for lighttpd's mod_flv_streaming module. I will also show how you can encode videos (.mp4 .mov .mpg .3gp .mpeg .wmv .avi) to the FLV format supported by Adobe Flash.

TSO helps in reducing cpu workload of packet cutting in 1500 byte and subsequently asking hardware to perform the same functionality. This features is enabled along with hardware support only.

When the only connections to a Linux system are the power cord and the Ethernet cable, sending the console output to another host on the local Ethernet is a great way to observe boot-time behavior, including any panics that hang the system.

Google's purchase of DocVerse March 5 validates the market for applications that bridge the gap between the Google Apps cloud computing suite and Microsoft's Office on-premise applications. Google will stitch this technology into Google Apps, appealing to customers who want to use Google Apps as their main collaboration suite, but still use the documents they created offline in Office without losing any of the data. The move comes as OffiSync is building its own suite of software that creates ties between Microsoft Office and Google Apps.

This week NVIDIA had to pull its latest WHQL-certified graphics drivers on Windows due to a bug that would cause the fan controller to not respond correctly to the current conditions of the GPU workload and in some cases would even turn the GPU's fan off. This bug could potentially kill the NVIDIA graphics card due to overheating. It turns out this potentially fatal bug is also present in their newest 195.36.08 and 195.36.03 Linux drivers.

There seems to be no respite from the predations of Microsoft FUD and the machinations of Big Business. Just when it seemed safe to come out of the closet and admit to being a user of free and open source software without being accused of being a Communist, it appears that we are now criminals too—even if we are not using pirated versions of proprietary software. The culprit this time is something called “Special 301”, an annual review of the status of foreign intellectual property laws carried out under the auspices of the Office of the US Trade Representative (USTR) which is an Executive Office of the President. It’s definition of criminal would make criminals of every single user of FOSS. Read the full article at Freesoftware Magazine.

One of the things that's been wandering around my mind lately (one of thousands) is the thought of the wild woods. In other words, places in the world that are away from civilization, away from the normal creature comforts of daily life, such as areas in Northern Canada, Alaska, Siberia, sections of Africa, and others like that. Places where you have enough power to run a machine, but no internet connection, or if you do, it's sparing at best. Places like this sometimes have computers, and a reasonable amount of use for one, but they're way outside the normal network connected sphere of influence you see in the regular world. That then begs the question, how do we get Linux into areas like that?

For any one running a linux desktop/server , the amount of free memory available on the system is one of the critical parameters that deterimine the system response. We will look at some commands which give you information about memory usage

The Wine development release 1.1.40 is now available. The source is available now, Binary packages are in the process of being built, and will appear soon at their respective download locations.

There are lots of ongoing efforts to increase the number of women participating in free software, but reports on how those efforts have fared are few and far between. Sarah Mei spoke at the Women in Open Source (WIOS) conference, which preceded SCALE 8x, to report on what she and other members of the San Francisco Ruby community have been doing to bring more women into that community. Her talk, Moving the Needle: How the San Francisco Ruby Community got to 18%, looked at the goals that were set, the methods that were used, and the results.

Canonical is updating Ubuntu's look and feel with a new style that departs from the popular Linux distribution's traditional brown theming. The new theme, which was announced yesterday as part of an initiative to overhaul Ubuntu's branding and visual identity, will be used in the upcoming Ubuntu 10.04 release, codenamed Lucid Lynx. The design documents that Canonical published Wednesday left a lot of questions unanswered. Fortunately, the new themes were rolled out to Ubuntu 10.04 alpha testers today in the latest set of package updates. We used the Ubuntu alpha to conduct some hands-on testing so that we could see how the new theme looks with a number of popular applications.

For the tinkerers and testers, 2010 is shaping up to be a perfect year. Almost every desktop and application we can think of is going to have a major release, and while release dates and roadmaps always have to be taken with a pinch of salt, many of these projects have built technology and enhancements you can play with now. We've selected the few we think are worth keeping an eye on and that can be installed easily, but Linux is littered with applications that are evolving all the time, so we've also tried to guess what the next big things might be.

For quite some time I’ve been intrigued by Ubuntu’s Netbook Remix (UNR), but I’ve never given it a shot up until now. Being a KDE guy, I usually lean toward applications based on the Qt toolkit and I’ve never really liked GNOME much. For some reason though, the Ubuntu Netbook Remix has been lingering in my mind for a potential review, and now I’ve finally been able to give it a shot. I’ve actually been using UNR for a couple of months now. When I first started playing with it, I didn’t even own a Netbook, so instead I tried it out on a Dell Latitude E6400 laptop. About a month later, I was gifted a Dell Mini 10 netbook, which afforded me the opportunity to try UNR in it’s intended environment.

The Free Software Foundation is gearing up for a big event March 19th through 21st to be held in Cambridge, Mass. at Harvard's University Science Center. LibrePlanet 2010 is a three day event with workshops on using free software for everything from Web development to video editing and graphics. This year's LibrePlanet is going to feature a new "Women's Caucus," a day-long track on Sunday to boost participation by women in free software projects. There's no shortage of events focused on free and open source software. You can't swing a penguin without hitting a conference these days, so we interviewed FSF membership coordinator Deborah Nicholson to find out what makes LibrePlanet different from some of the other events going on this Spring.
