There's a certain something in the air within the DevOps community right now. The movement is, to a certain extent, becoming a victim of its own success. For where there is buzz in tech, there is money. And where there is money, there are recruiters, there is marketing, there are misinformed and over-simplified tech articles and, let's face it, there are carpetbaggers galore.
Recently at work we’ve been on a “servicifying” kick, meaning we’re slowly converting our monolithic Django app into separate services. To start, this just means breaking up the existing runtime into pieces. Instead of one logical web process, we now have different ones for the web app, admin, login, apis, etc.
Wondering how much heap is used by Eclipse? Using the menu Window > Preferences there is a setting I can enable: “Show heap status“. With this, I see the current status of the heap in the lower right corner of Eclipse: The currently used amount of heap and the maximum of heap allocated.
Not all software we develop requires the same quality. It is not the same to develop software that will run only once, and will never need to be changed, that software that is expected to be used for years
Last time we developed brainfuck interpreter in Clojure. This time we will write a compiler. Compilation has two advantages over interpretation: the resulting program tends to be faster and source program is lost/obscured in binary.
As an architect you always have to stay open-minded, and be objective of any technology you happen to love.
Yesterday I gave a two-hour talk at Lambda Lounge Kraków on Pedestal (and some ClojureScript).

I have shown you how to process an plain HTML form with Spring controller. But a more powerful way to process form is to use Spring’s @ModelAttribute and its spring:form tags.
At last, I have the October screencast, as I promised weeks ago whilst in the USA. This is a reprisal of my JavaOne 2013 talk, which was called Test-Driven Development with Java EE 7, Arquillian and Enterprise Containers.
It seems that the Hazelcast Guys have solved the problem of JVM talking to each other
This week I’m in Postdam/Berlin giving a talk Infrastructure testing with Jenkins, Puppet and Vagrant at Agile Testing Days. Showing examples of using Puppet, Vagrant and other tools to implement a source code to production continuous delivery cycle.
In a lot of small startups, the initial phase is obviously on building a product. That’s the build phase, and not surprisingly you hire a lot of developers. As you should. But as you grow you may find the operational tasks that are defaulting to one or more developers are taking more and more of their time.
I recently helped a team to switch SVN servers and found a few gotchas along the way. This is a short guide on what worked for me and some stuff I tried that didn’t.
I’m leaving the “bad” code in the example above to show that the result is the same. Yes, it’s still a little ugly, but it’s much easier to follow and the code is self-documenting. What funky code have you written lately?
The Remote API that can be used to programatically interact with docker. I recently had a situation where I wanted to run many containers on a host with a single container managing the other containers through the API.

We're very proud to have one of the largest and most active communities of Java developers in the world, so of course when we decided to grow our team of Java developers we knew to look to Javalobby first.
While RedHat and Google have been dumping MySQL for MariaDB, there’s actually a third, much lesser-known option for MySQL-oriented database folks in the RDBMS market: CUBRID.
Every week here and in our newsletter, we feature a new developer/blogger from the DZone community to catch up and find out what he or she is working on now and what's coming next. This week we're talking to Sean Hull, author, speaker, and web performance and scalability expert.
