Loud Failures are Better than Silent, Faulty Behavior

Sometimes, small questions lead to big answers. Sometimes these answers are controversial. One such question is “What does this warning about serialVersionUID mean”? All the advice out there basically is for developers who don’t know what’s going on to write code that will ignore errors when something unexpected happens. In my view – this is exactly the wrong approach. The safe way to act is to make sure that your program crashes if you don’t have control.

There’s No Such Thing as a “Devops Team”

Lowering Mobile Development Barriers to Entry: SDKs in the Cloud

Icenium decouples compiler from platform -- so a dev can build an iOS app without xCode or a Mac, and web developers can use existing skills to build, test, and publish mobile apps to Android and iOS without platform-specific work.

Volatility in Adaptive Randomization

Randomized clinical trials essentially flip a coin to assign patients to treatment arms. Outcome-adaptive randomization “bends” the coin to favor what appears to be the better treatment at the time each randomized assignment is made. The method aims to treat more patients in the trial effectively, and on average it succeeds.

Algorithm of the Week: Bellman-Ford Shortest Path in a Graph

As we saw in the previous post, Dijkstra's algorithm is very useful when it comes to finding all the shortest paths in a weighted graph. However, it has one major problem! Obviously it doesn’t work correctly when dealing with negative lengths of the edges.

Grassroots Groovy: Parse XML with XmlSlurper from Java

We can introduce Groovy into our Java projects at grassroots level. Even if we aren't allowed to run the Groovy compiler we can use other ways to run Groovy code. As long as we can include the Groovy libraries as a compile dependency than we can already use Groovy from Java. In this post we see how we can use the power of XmlSlurper to parse XML from our Java code.
