An Introduction to Maatkit

nospam@example.com (Solomon K. Chang) — 2008-07-19T17:00:00Z

By Solomon Chang

Maatkit (available at http://www.maatkit.org) makes MySQL easier and safer to manage. It provides simple, predictable ways to do things you cannot otherwise do. It would be nice if these features were included with MySQL, but they are not. That's why Maatkit is now shipping by default with many GNU/Linux distributions such as Debian and CentOS.

You can use Maatkit to prove replication is working correctly, fix corrupted data, automate repetitive tasks, speed up your servers, and much, much more.

And best of all, Maatkit is Free Software so you can modify, inspect, and redistribute it yourself.

Multi-Instanced MySQL

nospam@example.com (Solomon K. Chang) — 2008-06-21T17:00:00Z

By Solomon Chang

There are whispered rumors from the remote corners of MySQL configuration gurus concerning the Dark Art of running more than one instance on MySQL on the same machine. Like a body possessed by a legion host of demons (well, MySQL daemons, actually), a single machine could serve multiple instances of MySQL that each may respond to different names, ports, and... dare I say it...? IP addresses! Oh, the horror! The terror! The memory consumption!
However, just as summoning and binding nether-worldly entities into an unwilling mortal shell has its own nefarious uses, so too does the black magic of invoking two or more instances of mysqld on the same single machine. Slowly and surely, it is a gateway for you to embark upon other unspeakable database experiments, such as Replication and Distributed Clustering, whilst obviating the need for any other machine. Replication with but a single computer, you say? Yea, it is an abomination! But this abomination you can configure for yourself while dangling your sanity between hard drive capacity and memory usage!
Muhahahahaha!

Managing MySQL Permissions

nospam@example.com (Solomon K. Chang) — 2008-05-17T17:00:00Z

By Solomon Chang

There comes a time in the life cycle of a company where everyone has to stop connecting as password-less root to their central database. All the inherent security protocols (such as "We only have 3 users," or "No one here is malicious enough or knowledgeable enough to crack our Production database!") begin to lose relevance as the DB user base starts to grow. This talk aims at the "why" and the "how" of setting user permissions, as well as how users are generally authenticated into the system. This talk also delves into the granularity of permissions for those who require extremely fine-tuned access to database resources.

An introduction to Flex - Chris Charlton

nospam@example.com (Solomon K. Chang) — 2008-04-19T17:00:00Z

Adobe Flex is a collection of technologies released by Adobe Systems for the development and deployment of cross platform, rich Internet applications based on the proprietary Adobe Flash platform. The initial release in March 2004 by Macromedia included a software development kit, an IDE, and a J2EE integration application known as Flex Data Services.

Flex is a hot (open source) topic this year and Linux users aren't left out. With the newly announced Adobe AIR for Linux and the upcoming Flex Builder 3 for Linux desktops, everyone can develop cross-browser/platform applications for the Web (SWF) or any popular desktop operating system (Linux, Mac OS X, Windows). Chris Charlton will be covering how to develop in Flex and deploy an RIA with one code-base while not having to worry about platform or browser differences.

So what is Flex and doesn't it cost money? The Flex SDK is free - containing a debugger, compiler, and the entire Flex framework. Adobe's IDE (Flex Builder) costs $250 (Standard Edition) and is free for students and teachers.

What's the difference between Flash and Flex? Why not just use Ajax? Good questions, but you'll want to attend the next LAMPSIG meeting to ask and find out!

A Tour of External Language Stored Procedures for MySQL - Antony Curtis

nospam@example.com (Solomon K. Chang) — 2008-03-15T17:00:00Z

The integration of Business intelligence and logic within the database has been a long requested feature for MySQL. With version 5.0, MySQL delivered a stored procedure implementation and here we extend it to provide general support for external language stored procedures.

We detail the philosophy and design of the external language stored procedure framework and its implementation within the server and libraries. We then also detail how an external language plug-in is written using the simple skeleton plug-in which exercises the basic interfaces between the server and external stored procedures.

Demonstrations using the already developed plug-ins, including an overview of the implementation for the simple XML-RPC and the more sophisticated Java plug-ins, writing stored procedures and functions, with ideas for applications and their utility.

This presentation includes a tour of the actual source code, highlighting the big picture. The audience will see the low impact of the main-line server code, the simplicity of writing plug-ins for new languages and the ease of using the language plug-ins already developed. This is an exciting new feature preview for MySQL. All demonstrations are with live running examples which everyone can try for themselves: No mockups, no screen-shots.

The ATK Framework - Jorge Garifuna

nospam@example.com (Solomon K. Chang) — 2008-02-16T18:00:00Z

ATK is a business framework written in PHP which allows you to build web applications with minimal amounts of code. ATK supports various databases, including: MySQL, Oracle, MSSQL and PostgreSQL.

The only code you write is business logic.

ATK philosophy

* Code minimization
* Don't repeat yourself
* Keep it simple

Usage

The framework is particularly useful for creating business applications; to manipulate data. CRM, HRM, ERP, CMS are all area's where ATK can be used to build custom applications with minimal effort.

Hard Drive Based NDB MySQL Cluster

nospam@example.com (Solomon K. Chang) — 2007-10-20T17:00:00Z

By Solomon Chang

NDB (Network Database) is an enterprise-grade, scalable, and highly available clustering storage engine - a share-nothing cluster that has no single point of failure - which is capable of running on inexpensive commodity hardware. NDB allows the construction of cheap, scalable, and exceptionally reliable database clusters, without expensive, specialized or additional hardware or software.

Back in June, Solomon Chang discussed the basic setup of a distributed, fault-tolerant, NDB Cluster for MySQL. The NDB storage engine has had one shortcoming, however: it has been traditionally memory-based.

As of MySQL 5.1, MySQL AB introduced a disk-based NDB solution, although its setup and configuration are significantly more complex than building a simple cluster. A disk-based cluster allows the administrator to spend less money on hardware costs by allowing him to commit larger NDB fragments to a single server. There will be a brief recap on the first Clustering lecture for those who are new to MySQL Distributed Clustering.

This clustering method can be implemented on as few as three computers that have been manufactured within the last decade. Come and hear how to do this and add this skill to your resume.

On Monday You Will Start Writing Tests

nospam@example.com (Jim Workman) — 2007-09-15T17:00:00Z

For many developers, testing their code is one of those tasks that they prefer to avoid as much as possible. But one of the easily applied aspects of Extreme Programming is the practice of test-driven development in which the tests are the first part of the development. We will look at the benefits of writing tests before
writing the code which it tests and how to use the PHPUnit testing framework to make the practice of writing tests for your code easy and even fun.

Open Q&A

nospam@example.com (Jim Workman) — 2007-08-18T17:00:00Z

This weekend will be an open Q&A session.

Storage Engines and Open Q&A

nospam@example.com (Jim Workman) — 2007-07-21T14:43:00Z

In MySQL, a storage engine is a mechanism or methodology by which data and indexes are archived and managed. Different storage engines have different features, and quite often different requirements. Solomon will provide a brief introduction to the various storage engines supported by MySQL and describe the environments most likely to use them.
This talk will be briefer than usual, and afterwards, there will be also an open Q&A session to see what topics members would like to see covered in the future.

MySQL Clustering with the NDB storage engine

nospam@example.com (Peter Benjamin) — 2007-06-16T17:00:00Z

Main Topic: MySQL Clustering with the NDB storage engine
Speaker: Solomon Chang

NDB is an enterprise-grade, scalable, and highly available clustering storage engine - a share-nothing cluster that has no single point of failure - which is capable of running on inexpensive commodity hardware. NDB allows the construction of cheap, scalable, and exceptionally reliable database clusters, without expensive, specialized or additional hardware or software.

A MySQL Cluster distributes processing over multiple servers, resulting in a single redundant and scalable solution. A cluster consists of a set of computers running MySQL servers to receive and respond to queries, storage nodes to store the data held in the cluster and to process the queries, and one or more management nodes to act as a central point to manage the entire cluster. There are many reasons for clustering a database and several different methods of clustering.

Solomon will discuss the creation, methodology, and usage of a MySQL Cluster, and demonstrate a cluster in practice with a series of virtual machines.
