  Collection Of Puzzles For Programmers

Did you know that we have a nice collection of puzzles here on less than dot? Some are harder than others so there is something for everyone. You can pic any language you want, you will see that there are solutions in Ruby, Python, Visual Basic, SQL, JavaScript, C++ and other. Here is a partial list of what we have Friday the Thirteenths The goal is to identify all friday the thirteenths for a given timeframe Regular Pentagon Given a grid co-ordinate (x,y) as the centre point of a regu...

  Clojure & Java Interop

About a year ago I got a phone call asking if I wanted to join another team at DRW. The team supports a (primarily) Java application, but the performance requirements would also allow it to be written in a higher level language. I'd been writing Clojure (basically) full-time at that point - so my response was simple: I'd love to join, but I'm going to want to do future development using Clojure. A year later we still have plenty of Java, but the vast majority of the new code I add is Cloj...

  Java SynchronizedList and Iterator

While reading some material about concurrency, I come up with some writing about using SynchronizedList wrap about normal List to enable synchronization.   But one interesting thing is http://docs.oracle.com/javase/7/docs/api/java/util/Collections.html#synchronizedList%28java.util.List%29   It says     It is imperative that the user manually synchronize on the returned list when iterating over it:     1   List list = Collections.synchronizedList(new A...

  The Basics of jQuery

So, a while back I had an internal presentation at work about this topic. A few good friends in the community took a look at my slides, and they thought it would make a nice blog post because “there can’t be too many good posts about jQuery introduction and best-practices.” Whether this post is going to be good or not, is up to you but I’ll try to outline what jQuery is, and how you can start working with it. For most of you, this will just be a re-cap and probably...

  Optimization Tricks used by the Lockless Memory Allocator

With the releasing of the Lockless Memory Allocator under the GPL version 3.0 license, we can now discuss more of the optimization tricks used inside it. Many of these are things you wouldn't want to use in normal code. However, when speed is the ultimate goal, sometimes we need to break a few rules and use code that is a little sneaky.The SlabA slab is a well-known technique for allocating fixed size objects. For a given object size, a chunk of memory is divided up into smaller regions of that ...

  Java API vs Framework

What is the difference between a Java Library and a framework? The two concepts are essentially important for a Java developer. The most important difference between a library and a framework is Inversion of Control. It means that when you call a library you are in control. But with a framework, the control is inverted: the framework calls you. (This is called the Hollywood Principle: Don’t call Us, We’ll call You.) This is pretty much the definition of a framework. Basicall...

  Make Big Data Collection Efficient with Hadoop Architecture and Design Tools

Hadoop architecture and design is popular to spread small array of code to large number of computers. That is why big data collection can be made more efficient with hadoop architecture and design. Hadoop is an open source system where you are free to make changes and design new tools according to your business requirement.   Here we will discuss most popular tools under the category Hadoop development and how they are helpful for big projects. Ambari and Hive– When you are designing...

  The Future of JavaScript � take a peek today!

The ECMA committee is working hard on designing the next version of JavaScript, also known as "Harmony". It is due by the end of next year and it is going to be the most comprehensive upgrade in the history of this language. Chrome and V8 are committed to pushing JavaScript forward and have already started implementing the new features. You can try some of them today in the latest dev channel release. Here’s a summary: Lexical scoping. Now "let" is the new "var" – traditional "var...

  What's on your Learning List?

How do you track and decide what topics you want to spend time learning? For a while, I didn’t have a real good solution. Something would trigger me to remember “Oh yeah! I really wanted to learn more about that”. I would spend the evening doing busy learning - it seemed like I was learning but I really wasn’t. Instead of trying to do Deliberate Practice, I’d fool myself into thinking I was investing my time wisely by reading blog posts and examples but no...

  The Go Programming Language Turns Two

Two years ago a small team at Google went public with their fledgling project - the Go Programming Language. They presented a language spec, two compilers, a modest standard library, some novel tools, and plenty of accurate (albeit succinct) documentation. They watched with excitement as programmers around the world began to play with Go. The team continued to iterate and improve on what they had built, and were gradually joined by dozens - and then hundreds - of programmers from the open source...
