Hotspot Patterns: The formal definition and automatic detection of architecture smells

International Conference on Software Architecture, 2015 Yesterday we looked at Design Rule Spaces (DRSpaces) and how some design rule spaces seem to account for large numbers of the error-prone files within a project. Today’s paper brings us up to date with what the authors learned after examining hundreds of error-prone DRSpaces… After examining hundreds of error-prone DRSpaces over dozens open source and commercial projects, we have observed that there are just a few distinct types of architecture issues, and these occur over and over again. We saw these issues in almost every error-prone DRSpace, in both open source and commercial projects. There are five architectural hotspot patterns that are frequently the root causes of high-maintenance costs: Unstable interfaceImplicit cross-module dependencyUnhealthy interface inheritance hierarchyCross-module cycleCross-package cycle.

Why Your Idea Might Not Make It Into UE4 – Headcrash Industries. So you’ve had this great idea for a new feature in Unreal Engine.

Why Your Idea Might Not Make It Into UE4 – Headcrash Industries

It makes complete sense, will be useful to so many users (but especially yourself), and shouldn’t be too difficult to get up and running for experienced guys like us. Even your friends on the Forums and AnswerHub like it, and yet there has been absolutely no traction for months. So what is going on? This is a question I am confronted with almost daily, and I often have to cut the answer short. This article attempts to explain in more detail some of the main factors that affect the decision of whether and when a new feature will be implemented in UE4. Opportunity Cost.

Optimize for Happiness. A happy programmer is a productive programmer.

Optimize for Happiness

That's why we optimize for happiness and you should too. Don't just pick tools and practices based on industry standards or performance metrics. Less Software. You'd think that twice as much code would make your software only twice as complex.

Less Software

But actually, each time you increase the amount of code, your software grows exponentially more complicated. Each minor addition, each change, each interdependency, and each preference has a cascading effect. Keep adding code recklessly and, before you know it, you'll have created the dreaded Big Ball of Mud. The way you fight this complexity is with less software. Less software means less features, less code, less waste. The key is to restate any hard problem that requires a lot of software into a simple problem that requires much less. Less software means you put away the crystal ball. From the beginning, we've designed our products around the concept of less software. Less software is easier to manage. Which features you choose to include or omit have a lot to do with less software too. Architecture in an Agile world. This Blog is a kick off to for many writings about architecture in an Agile World. We will explore the topic from all the views possible, in order to gain a better understanding about it.

By doing so, we hope to create a community of followers, who would also like to contribute or discuss about this topic. Xebia is helping many organizations in the Netherlands, France, the United States and India with implementing an agile way of system development. In most of the cases the Scrum method is applied and very good results are achieved. Business and IT are working much closer together, resulting in more quality and much more customer satisfaction. The scrum masters in the teams are not able to solve all this. The picture below shows how Scrum synchronizes the business cycles with the IT project cycles.

Therefore, architecture in the agile world has a very important role to play. In the coming months we will write a series of blogs, about several aspects of architecture in the agile world. Cleaning bad code. Guess what!

Cleaning bad code

You’ve just inherited a stinking, steaming pile of messy old code. Congratulations! It’s all yours. Bad code can code can come from all kinds of places. Middleware, the internet, perhaps even your own company. Built here? No, thanks. Sharing code « #AltDevBlogADay. Making it easier to share efficient cross-platform code with others keeps me busy.

Sharing code « #AltDevBlogADay

I continue sharing a few thoughts about build systems, software licenses and code re-usability. Premake Last time I spoke about meta build systems, and following some suggestions I decided to finally give premake a try. I’m happy to report that it is doing a great job so far. Even though I had never used premake before, it only took an afternoon to have it auto generate Visual Studio, Mac OSX Xcode projects and Unix Makefiles the way I like it. Premake takes away the suffering from cmake: its project files use relative paths so you can share its generated project files with others. Physics Effects is a low level collision detection and rigid body dynamics library, optimized by Sony for the PlayStation 3 SPUs and for their new PSP2 ARM handheld. Open source licenses In order to share code with game developers and film studios, you need to pick the right software license.
