JavaScript Wars: Xtend

And so Java, the old old King is still alive.

After Scala, Clojure, NodeJS, and Dart, a new hero is knocking to its castle: Eclipse Xtend

Will he succeed? Hard to Say, but Xtend is very similar to CoffeScript: Xtend simplifies writing Java code, but it doesn’t aim take the grab the crown with a night ambush to the King’s IDE.

At the moment Xtend do not spot a strong IDE, but its simplicity could give it a plus.  Xtend gives us less stuff then Scala, and mimics a lot C# feature like extension method and lambda function. But it is still a baby in a world of fighters, so keep an eye on it but do not write too much code with it, for the meantime…

The Javascript world bring to us a deadly news: the planet Flex has been attacked by the Html5 rebels. Adobe seems to retire from the Flex development, and also flash mobile has having a bad day (try to find it on moder android devices!).

And if Flex&Flash are dying, Silverlight is even less lucky!…he is riding in the black forest, during a bad storm.

So it is hard to say what the fucture deserve us…but grab another table, because the last royal feast will be full of new programming languages!

 

 

Unison File Synchronizer

Several years ago I had the need of keep in sync three computers.  After some questions on a java mailing list, a very smart guy suggested me Unison.


Unison is a file-synchronization tool for Unix and Windows. It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other.

Unison shares a number of features with tools such as configuration management packages (CVS, PRCS, Subversion, BitKeeper, etc.), distributed filesystems (Coda, etc.), uni-directional mirroring utilities (rsync, etc.), and other synchronizers (Intellisync, Reconcile, etc). However, there are several points where it differs:[…]

Unison seems a bit lost in cyberspace (no new features) but the users mailing list spot some activity, so I will suggest to give it a try, because its sync alghoritm is very well written, and the MS-Window interface is good.
