Existing Values The initial signatories of the Agile Alliance sat (stood according to the Snowbird summit photo) and hashed out some common values in their Agile Manifesto in 1998. Here’s the key four values that they came up with: “… we have come to value: 1. Individuals and interactions over processes and tools 2. Working software over comprehensive documentation 3.

Autoboxing is clear for all Java developers since Java 1.5 Well, I may be too optimistic. At least all developers are supposed to be ok with autoboxing. After all there is a good tutorial about it on the page of ORACLE.Autoboxing is the phenomena when the Java compiler automatically generates code creating an object from a primitive type when it is needed. For example you can write: ...

ExtJS comes with a singleton class Ext.QuickTips (alternate name: Ext.tip.QuickTipManager) which provides attractive and customizable tooltips for any element. The QuickTips singleton is used to configure and manage tooltips globally for multiple elements in a generic manner.

Originally Written by Justin SwanhartThere are a lot of tools that generate test data.  Many of them have complex XML scripts or GUI interfaces that let you identify characteristics about the data. For testing query performance and many other applications, however, a simple quick and dirty data generator which can be constructed at the MySQL command line is useful. Preview...

Eclipse projects have the nice features that they can link to files and folders: so instead of having the physical file, it is just a pointer to a file. This is very cool as that way I can point to shared files, or keep files in a common place referenced from projects, and so on. Preview Text:  Eclipse projects have the nice features that they...

Ruby unit testing feels very nice and natural to write with RSpec. Since I started working with Ruby more often that is one of the things I liked the most. However I still love Java (or for this particular example anything with strong typing) and is still my main language, and in many cases is superior to Ruby. One of those is the value of Unit Tests over the long run and as safety net and aid...

It's fair: you're interested in NoSQL, but maybe your team doesn't have the resources to fully commit just yet. Even if you narrowed down your options and avoided the urge to relapse entirely into SQL, analytics presents a problem, because NoSQL is, in many ways, a developer's baby; for those just trying to get a look at the data, it's fairly inaccessible.

Technical debt is something we, as developers, live with every day. Sometimes a pragmatic solution needs to take precedence over a perfect solution. A software craftsmanship purist would argue that you should always strive for the perfect solution but in my opinion this is not always practical. Preview Text:  Technical debt is something we, as...

UI application development that presents and changes data in a data store, is at least an order more expensive than it was 20 years ago. It really shouldn’t be given all that “progress” embodies.

An interesting (and informative!) video has come out of the recent DockerCon Hackathon. The video elaborates on how to manage Docker containers with ElectricCommander and demonstrates what the pipeline for that process is going to look like (it definitely involves Github, Jenkins, and Docker itself within the pipeline, as well an Nginx). There's actually two different videos, and both have strong...

Anyone who has done multithreading in the past won't deny how hard and painful it is to manage multithreaded applications. I said manage because it starts out simple and it became a whole lot of fun once you start seeing performance improvements. However, it aches when you see that you don't have a easier way to recover from errors in your sub-tasks OR those zombie bugs that...

Ever wonder why your Sequence numbers in NuoDB are not necessarily assigned in sequential order? Sequences can be used to auto-generate unique values, such as the primary key column of a table. Sequences also do not respect transactional isolation so they will not cause conflicts if multiple transactions are using the same sequence at the same time. This is why using a Sequence is...
