Good Bye Redeployment. spring-loaded, an Opensource Classreloader

Redeem yourself from hot deployments and OutOfMemoryException. spring-loaded is an opensource classreloader and a promising alternative to JRebel. It does not offer as many features as JRebel does, and it does not support any framework just yet. Nevertheless, its a great tool that can save the time you are waiting for that servletcontainer to restart again.

What it can do:
  • add/modify/delete methods/fields/constructors
  • modify annotations on types/methods/fields/constructors
  • add/remove/change values in enum types
What it cant:
  • support framework specific changes like Spring MVC @RequestMappings
  • change log configuration on the fly
It is not getting the attention that it deserves, so give it a try.

Just download from github already, and add the following to your JVM parameters:
java -javaagent:<pathTo>/springloaded-{VERSION}.jar -noverify

8 Things you should not be afraid of as a Developer

Change In Software Development there is no such thing as stagnancy. Everything you develop now is just another version of a component that will probably change in the future. Change is the most common thing in Software Development, and you're better of accepting it as a fact. Expect future changes to everything you develop, and therefor design your Code more modular. This makes changes more easy and increases the Quality at the same time. Adapt the concepts of DRY and YAGNI . You will often come to the Situation, where you look at your Code and imagine that you could have done that "better". Don't let this thought prevent you from sleeping. Take action immediately and Refactor ! If you don't do it now, you will probably never do it. The longer you wait, the harder and more costly it gets. And you slowly grow up a mess you cant deal with anymore. "Good code is code that is easy to change. Code tends to change until it is no longer easy to change. All code bec...

So we just got back from a little Canadian weekend with Thee Oh Sees. We had a blast. There is a lot going on in our world at the moment so we've been a bit busy - sorry for the lack of updates here. We have a whole bunch of upcoming shows, check out the shows section to your right - these include shows with SEX CHURCH, a mini-tour with PYGMY SHREWS, a couple of shows with RUSSIAN CIRCLES, and a little European tour in December. If any of you euros cant make it to see us in December, we will be back in January for a little over a month, and we are very excited. We have a new LP done, it will be out in March on Sacred Bones Records and much touring in support of it shall follow. We have also been informed that Karmic Swamp Records is repressing the "Think" 7" that came out last year. There were only a handful of those pressed so hopefully people that missed out on getting them can grab one now. We will post here when it is available. Also, thanks to everyone who has o...

Why REST is so important

Image
This post is dedicated to REST, an architectural style of shaping webservices and the most misunderstood concept in the history of IT. This post is addressed to you who is designing webservice apis not being fully aware what REST actually means. I'm trying to give you the idea. This post is also addressed to you who think to know what REST means, when in reality you have no clue, just yet. Yes i have met such people in the past - plenty of them. It's not going into the details of the Richardson Maturity Model , and it's not gonna make you a REST expert. There are plenty of guides on the web for that: slides, youtube videos, blogposts, books and more. Rather than going into the details, i'm going to link some good resources at the end of this post. So lets start with The meaning of REST Representational State Transfer. This sentence is not only what REST stands for, it is also the tiniest possible description of what REST actually means. Didn't get it? Read it aga...
