The term "Microservice Architecture" has sprung up over the last few years to describe a particular way of designing software applications as suites of independently deployable services. While there is no precise definition of this architectural style, there are certain common characteristics around organization around business capability, automated deployment, intelligence in the endpoints, and decentralized control of languages and data.

I really have very little to say on the recent debate surrounding the future viability of podcast networks. To me, it seems a lot like the age-old flame wars comparing Macs and PCs, and the more recent and equally bombastic arguments over iOS versus Android: everyone has their own personal preference, and we must all accept that. Taken a step further, everyone has their own personal preference, we need to accept that, and no one will ever c..

Master SDN hacker Flavio sent me some tunes. They were sitting on my desktop in a folder: $ ls ~/Desktop/ uncopyrighted_tunes_from_flavio/ I wanted to listen them while hacking, but what was the easiest way…? I wanted to use the nautilus file browser to select which folder to play, and the totem music/video player to do the playing. Drop a file named totem into: ~/.local/share/nautilus/scripts/ with the content..

It’s sad to see tourism and capitalism ruining the way of life for a people whose traditions go back generations and hundreds of years. You might not agree with their beliefs, or may even go so far as to boldly proclaim the Amish lifestyle nothing more than a sham to avoid taxes; but regardless if your own personal opinions, I think we can all agree that this is unfortunate.

Introduction If you are building any kind of application for a consumer based product, it is common to have large amounts of application data being generated about your users. Running reports is a traditional use of this data, but what if you could make this data actionable? What if you could adapt the user experience by aggregating and testing this data against rules that could dictate actions or special messaging? In this post I a....

pThe backend for theScore mobile apps consists of many different web services (Core Sports, Personalization, Push Alerts, etc.). Each service provides its own RESTful API. Some of these services are internal. As such, they only have a very limited number of consumers. Having a limited number of consumers for an API lets you keep the authentication really simple for that API./p pFor the purposes of this blog post, suppose that we have two se....

We’ve been spending an excessive amount of time tuning our garbage collection and memory management of the new iOS VM based on profiler output. This is one of the cool features in the approach we took (translating Java to C rather than going directly to machine code), we can use Apple’s nifty profiling tools to see where the CPU/GPU spend their time. After quite a few profiling sessions it became apparent that the GC is the main reason fo..

It’s often said, especially by those who profess to understand Apple on a fundamental level, that the company is not in the business of making strictly hardware or software, or even iPhones and Macs. However, although that realization comes readily enough, the gap it leaves explaining what, exactly, Apple does do if not build computers and operating systems, has proven elusive at best. After WWDC though, we have another great opportunity to..

Function composition is one the key features (among others) of functional programming. Programming languages that offer higher order functions as a feature can potentially use function composition. But, still, programmers need to be aware of some key concepts to successfully apply this pattern in our code. Function composition, as defined on Wikipedia, is an act or mechanism to combine simple functions to build more complicated....

On my last project, the client categorically asked the team to ensure that the Django app we were developing had first-class support for Internet Explorer 8. Now I know a number of developers who would cringe at the mere mention of Internet Explorer (IE). I have even heard it said that the only use of Internet Explorer is to download an alternative browser! What do you do when you need to set up a test suite that supports the running of fun..

If you've spent any amount of time running a Linux machine on a Windows network, you've probably had the need to share files between the two. This seems like it should be a trivial matter, but as often as not, it seems to produce bouts of sheer insanity. The problem usually lies in the realization that Windows uses SMB and that Linux tends toward transit over SSH (rsync, scp, sftp.)

Another short list for you, unfortunately; apologies. I hope that before too long, I will be able to turn out the impressive rosters of days since past and once again shine my admittedly meager spotlight on some work truly worthy of recognition. Until then, though, I have but two recommendations for you: Permalink.

In 1995, Fluxus artist Dick Higgins created the Intermedia Chart, a Venn diagram describing overlapping academic art traditions. The most important aspect of this static chart, in my opinion, were the unknown circles labeled with a question mark. To represent this motion and fluidity in a dynamic way, I created a rough interactive version using […]

When we introduced the idea of the EDT from Swing (and pretty much any modern UI toolkit) into what eventually became Codename One, one of the chief benefits was modal dialogs. It’s the ability to block the executing thread in order to ask the user a question, that’s a very powerful tool for a developer. As a result of that we defined modal dialogs the way Swing/AWT defined them: stopping the execution of the code.

Our animator Antonio has been hard at work on new animations. Check it out! Guys, the level editor is really close to being done. Here's some cool features: You can link entities together. For example, you can have a door open when the player enters a trigger volume. Or have a light turn on. Or both. The UI now displays buttons for all available commands at any given moment, and their keyboard shortcuts. Different comman..

There is a rather nice blog post on the Sphinx Search blog about how searchcode uses sphinx. Since I wrote it I thought I would include a slight edited for clarity version below. You can read the original here . I make it no secret that the indexer that powers searchcode is Sphinx Search which for those who do not know is a stand alone indexing and searching engine similar to Solr. Since searchcode’s inception in 2010, Sphinx has..

Introduction Closures in Go are a very powerful construct but they can also be the cause of bugs if you don’t understand how they work. In this post I am going to pull a small piece of code from Chapter 2 from the Go In Action book that discusses a pitfall you can run into when using closures. The full code example can be found in the Github repository for the book. Chapter 2 discusses this code example in full detail. The Clos..

Technology specialists are competing for designers and big business strategy firms are gobbling up entire agencies and boutiques whole. What’s going on with this wholesale rush to stitch together firms from tribes with wildly different professional disposition?

The points I'm going to discuss here helped me a lot to become more aware of my tests and what I can do to improve them. If you have experience in writing tests, you probably know most of what I'm going to talk about, but it's still good to refresh your memory and add more references on the subject. If you have just started writing tests and are looking for ways to become even better, then you came to the right place!

I’ve been having fun looking at the betfair market odds of a team winning the world cup over time. The interesting thing isn’t the wins and losses, although those are very clear, but how they affect the other teams chances. The vertical axis is the % chance of winning, as predicted by the betfair market after the end of play each day. In some cases a team wins but their performance was so unconvincing that their chances of winning the t....

If you run Sphinx Search you may want to estimate the amount of RAM that it requires in order to per-cache. This can be done by looking at the size of the spa and spi files on disk. For any Linux system you can run the following command in the directory where your sphinx index(s) are located. ls -la /SPHINXINDEX/|egrep "spa|spi"|awk '{ SUM += $5 } END { print SUM/1024/1024/1024 }' This will print out the number of gigabytes required to st..

In Africa, there’s a saying: “If you want to go fast, go alone. If you want to go far, go together.” It’s a great mindset with regard to software design and development - we should always encourage a joint working environment. One way to “go together” is through workshops. We do it a lot at Thoughtworks - whether it’s to kickoff a Discovery phase around developing new product propositions or initiating a new phase of work in what we call an..
