David Euler on programming, design and linux. Follow these steps to speed up your eclipse as a super fast IDE , it works for 32 & 64 bit version eclipse/jdk on my windows 7 x64. 1.Disable antivirus software, or add your jdk & eclipse & workspace & other related folder to white list in your antivirus software. 2.Disable unecessary validations and startup action in eclipse reference. For validations: on eclipse menu Windows -> Preferences -> Validation, click “Disable All”, and then select the validator which you need. I selected “Classpath Dependency Validator” only.

For startup action: on eclipse menu Windows -> Preferences, type “startup”, select “Startup and Shutdown”, untick the options you don’t need. 4.Create a ram disk(virtual disk) on memory, and put your jdk on the ram disk. Then set the ImDisk driver to auto-load at Command Prompt with administrative privileges (for example right-click, start as Administrator), type: sc config imdisk start= auto net start imdisk then you should format the ram disk manually.

Agile software development is designed to thrive within even the most dynamic business and technical environments.

An Agile Approach to Change Management - Articles - Articles, News, Etc. : Agile Software Development

In fact, according to an article on the Web site of Martin Fowler, a well-known Agile industry leader, the name “Agile” was chosen because its founders viewed “adaptiveness and response to change” as the most essential concept of the methodology. Authors : Dr. Myles Bogner and David Elfanbaum, Asynchrony Solutions Figure 1. The Domains of Agile Methodology and Enterprise Change Management All Agile methodologies include integrated practices and processes that manage evolving requirements to efficiently develop a continuous stream of new software capabilities. Each of these challenges is compounded when organizations operate multiple Agile projects simultaneously. Enterprise Change Management (ECM) provides a framework that addresses many of these missing factors. Android app development 101: Preparing environment part 2. This is the second part of 2 posts.

Android app development 101: Preparing environment part 2

During these posts you will learn how to set up your windows environment for Android app development. In the first part ( located here: part 1 ) we downloaded & installed Java / the Android SDK and Eclipse. This post will cover the following: Configuring Eclipse for Android developmentInstall the latest Android SDK's versionsMaking a Virtual Android device After this post you will be able to continue to the first tutorial: [Beginner tutorial: Hello World].

Configuring Eclipse for Android development We almost have all the tools for Android app development. Start Eclipse, then select Help > Install New Software....Click Add, in the top-right corner.In the Add Repository dialog that appears, for the Name enter "ADT Plugin" Enter the following URL for the Location: OK.In the Available Software dialog, select the checkbox next to Developer Tools and click Next.In the next window, you'll see a list of the tools to be downloaded. Canned Platypus » Blog Archive » How To Ruin a Project. This is a bit of a riff on Jerry Weinberg’s ten commandments of egoless programming (via the also-excellent Jeff Atwood).

Canned Platypus » Blog Archive » How To Ruin a Project

I’ve found that many engineers, perhaps even a majority, respond more to aversion than to encouragement, so a “how not to” that can be inverted in one’s head sometimes works better than a “how to” taken straight. So here are the ways to turn a promising and fun project into a soul-sucking wreck. Take it from an expert. Miss the point. The Ten Commandments of Egoless Programming. Genetic Algorithm For Hello World. This article works through the creation of a ‘toy’ genetic algorithm which starts with a few hundred random strings and evolves towards the phrase “Hello World!”.

Genetic Algorithm For Hello World

It’s a toy example because we know in advance what the optimum solution is – the phrase “Hello World!” – but it provides a nice simple introduction to evolutionary algorithms. I have written this article primarily for developers who have a casual interest in machine learning. I don’t talk much about the implementation of the code itself because there’s not much of interest there – the beauty of genetic algorithms is their simplicity, so the code isn’t that interesting, other than in as much as it’s not usual to do such things in JavaScript.

For ‘real’ applications of genetic algorithms, I’d suggest looking into existing established frameworks for your language. Mercurial – some useful links when you are about to start « Tomasz Dziurko. SOA anti-pattern: Transactional Integration. It all starts with a business requirement – as it always should.

SOA anti-pattern: Transactional Integration

We have an ordering system (say the same one from the Knot anti-pattern) and the business says they only want to confirm an order to the user if the item is already secured for that order in the stock. From the technical point of view we have 2 separate services – one handles orders the other handles the stock – now what? Figure 10.1 A vanilla ordering scenario. An Ordering service needs to confirm item in stock before confirming order for customer. This sounds like a text book case for using transactions but in reality it isn’t. Transactions basically build on four basic tenets: Atomicity, Consistency, Isolation and Durability (ACID):

An Introduction To Cassandra: The Data Model. I'm fairly new to the whole NoSQL game, and one thing I keep hearing is how great Cassandra is.

An Introduction To Cassandra: The Data Model

Built by Facebook and open sourced in 2008, Cassandra is probably the most popular NoSQL implementation: "A massively scalable, decentralized, structured data store". Cassandra takes it's distribution features from Dynamo and the data model from BigTable. Before we look at using Cassandra, we first need to understand the data model. For developers new to Cassandra, coming from a relational database background, the data model can be a bit confusing.
