A Googly MySQL Cluster Talk

Here's a video about mySQL ndbcluster presented during google tech talk. The presenter is Stewart Smith who works for MySQL AB as a software engineer working on MySQL Cluster. He is an active member of the free and open source software community, especially in Australia.


ABSTRACT
Part 1 - Introduction to MySQL Cluster The NDB storage engine (MySQL Cluster) is a high-availability storage engine for MySQL. It provides synchronous replication between storage nodes and many mysql servers having a consistent view of the database. In 4.1 and 5.0 it's a main memory database, but in 5.1 non-indexed attributes can be stored on disk. NDB also provides a lot of determinism in system resource usage. I'll talk a bit about that.

XAMPP - LAMP in a box

With the infocard buzz going around..., and the possible opensourcing of it's components and code that enable users to easily deploy infocard, I thought that it would be nice if there could be more folks from the community who could actually try it out from a "deployment" perspective rather than from a "user's" to better understand how the whole thing works. But unlike me, not everybody has access to servers, and other necessary resources to deploy such a solution. I thought of making it easier for those who do not have servers but just a desktop and/or a laptop to install a webserver (ie: Apache), php, perl, sendmail, mysql DB, a FTP server (ie: filezilla), a mail server (ie: mercurymail), webdav, a mysql DB administrator (ie: phpmyadmin), a weblog analyzer (ie: webalizer), OpenSSL, etc.. at the click of a button.. No, No, I didnt develop anything new, but am pointing you to something that exists out there that would enable you to do ALL OF THE ABOVE. introducing: XAAMP from Apache Friends.
The philosophy behind XAMPP is to build an easy to install distribution for developers to get into the world of Apache. To make it convenient for developers XAMPP is configured with all features turned on. The default configuration is not good from a securtiy point of view and it's not secure enough for a production environment : please don't use XAMPP in such environment. Since LAMPP 0.9.5 you can make your XAMPP installation secure by calling ┬╗/opt/lampp/lampp security┬ź XAMPP for Linux The distribution for Linux systems (tested for SuSE, RedHat, Mandrake and Debian) contains: Apache, MySQL, PHP & PEAR, Perl, ProFTPD, phpMyAdmin, OpenSSL, GD, Freetype2, libjpeg, libpng, gdbm, zlib, expat, Sablotron, libxml, Ming, Webalizer, pdf class, ncurses, mod_perl, FreeTDS, gettext, mcrypt, mhash, eAccelerator, SQLite and IMAP C-Client. XAMPP for Windows The distribution for Windows 98, NT, 2000 and XP. This version contains: Apache, MySQL, PHP & PEAR, Perl, mod_php, mod_perl, mod_ssl, OpenSSL, phpMyAdmin, Webalizer, Mercury Mail Transport System for Win32 and NetWare Systems v3.32, JpGraph, FileZilla FTP Server, mcrypt, eAccelerator, SQLite, and WEB DAV & mod_auth_mysql. XAMPP for Mac OS X The distribution for Mac OS X contains: Apache, MySQL, PHP & PEAR, SQLite, Perl, ProFTPD, phpMyAdmin, OpenSSL, GD, Freetype2, libjpeg, libpng, zlib, Ming, Webalizer, mod_perl, eAccelerator, phpSQLiteAdmin. WARNING: This version of XAMPPis still in the first steps of development. Use at you own risk! XAMPP for Solaris The distribution for Solaris (developed and tested with Solaris 8, tested with Solaris 9) contains: Apache, MySQL, PHP & PEAR, Perl, ProFTPD, phpMyAdmin, OpenSSL, Freetype2, libjpeg, libpng, zlib, expat, Ming, Webalizer, pdf class. WARNING: This version of XAMPP is still in the first steps of development. Use at you own risk! XAMPP is free of charge We don't like overpriced commercial software and XAMPP is our attempt to do something that shows free software doesn't have to be bad. Easy installation and deinstallation To install XAMPP you only need to download and extract XAMPP, that's all. There are no changes to the Windows registry (not true if you use the Windows installer version of XAMPP ) and it's not necessary to edit any configuration files. It couldn't be easier! To check that XAMPP is working some sample programs are included, there is a small CD collection program (written in PHP using MySQL) and a small guest book software (written in Perl) and several other demonstration utilities. If you decide that XAMPP isn't needed any more just delete the XAMPP directory and it's completely removed from your system. If you use the Windows installer version of XAMPP it's recommended to use the uninstall feature. As every installer do the installer will make registry entries to remember the install. The license XAMPP is a compilation of free software (comparable to a Linux distribution), it's free of charge and it's free to copy under the terms of the GNU General Public License. But it is only the compilation of XAMPP that is published under GPL. Please check every single license of the contained products to get an overview of what is, and what isn't, allowed. In the case of commercial use please take a look at the product licenses (especially MySQL), from the XAMPP point of view commercial use is also free.
Happy LAMP... oops... XAMPPing.
