The musical world of Java

Recently whilst browsing through Geertjan’s blog, to keep myself abreast with the technological happenings of Netbeans; I stumbled upon an interesting write-up which discussed about a Java API for music, namely JFugue. Being inclined to music since my early days, the short write-up immediately caught-up my attention. I didn’t have enough time in hand to investigate it in detail; however, least I had a look at the API’s “programming” guide and was really astonished to find that now one can define musical scores, notes etc. and program an entire virtual orchestra to play and record the same in standard MIDI format.

Following are some more musical Java APIs -

Now that’s definitely music to ears for all the programmers out there who have a musical predilection.

Shard – A Database Design

Scaling Database is one of the most common and important issue that every business confronts in order to accommodate the growing business and thus caused exponential data storage and availability demand. There two principle approaches to accomplish database scaling; v.i.z. vertical and horizontal. Regardless of which ever scaling strategy one decides to follow, we usual land-up buying ever bigger, faster, and more expensive machines; to either move the database on them for vertical scale-up or cluster them together to scale horizontally. While this arrangement is great if one has ample financial support, it doesn't work so well for the bank accounts of some of our heroic system builders who need to scale well past what they can afford. In this write-up, I intend to explain a revolutionary and fairly new database architecture; termed as Sharding, that some websites like Friendster and Flickr have been using since quite sometime now. The concept defines an affordable approach t...

FAINT - Search for faces

Lately, I've been playing around a bit with facial pattern recognition algorithms and their open source implementations. I came across many reference implementation but a very few were implemented in Java, and the Eigenfaces algorithm by far happens to be the best amongst them all. During my research around the said topic i happened to stumble-upon an implementation called FAINT (The Face Annotation Interface - http://faint.sourceforge.net). Faint by far the best facial pattern recognition API and as you must have already guessed, it implements the Eigenfaces algorithm. Now enough of theory talks, how about implementing an example with faint...? Here is one for all you face-recognition enthusiasts. The following example simply searches for faces in a given photograph and thumbnails them. Now, I know thats not face recognition; but be a little creative here. Once you have the facial thumbnails extracted, its never a big deal to look further in the Faint API and find methods which ca...

Is Java String really immutable...?

In many texts String is cited as the ultimate benchmark of Java's various immutable classes. Well, I'm sure you'd have to think the other way once you have read this article. To start with, let's get back to the books and read the definition of immutability. The Wikipedia defines it as follows - 'In object-oriented and functional programming, an immutable object is an object whose state cannot be modified after it is created.' I personally find this definition good as it mentions that an immutable instance's state should not be allowed to be modified after it's construction. Now keeping this in the back of our minds, let's decompile Java's standard String implementation and peep into the hashCode() method - public int hashCode() { int h = hash; if (h == 0) { int off = offset; char val[] = value; int len = count; for (int i = 0; i h = 31*h + val[off++]; } hash = h; } return h; } A detailed ...
