Articles, notes and random thoughts on Software Development and Technology
Spring and EJB3.0 both aim to simplify application component development: Spring has dependencies and characteristics of your classes (transaction support etc) externalized to an XML file, whereas the new EJB3.0 spec annotates the actual source file with markup alongside the actual code.
This article on the OnJava.com website gives a simple comparison between the two approaches.
So what was the 3G service advertised about 3 years ago when I eagerly raced out to buy one of the new phones for 250 bucks? I think Sprint (and others) jumped the gun somewhat, as that service (later known as 2.5G) only reached averages of around 120kbps.
Nice to know though that wireless broadband is finally a reality.
Microsoft have recently changed their strategic oulook on the use of Linux and Open Source software, and rather than attempting to face the juggernaut head-on, they are now attempting work with and complement Linux and Open Source technologies.
So have Microsoft admitted defeat? Five years ago, Steve Balmer publically called Linux and Open Source a ‘cancer’ on commercial software development. At that time Microsoft was running scared and was attempting to sell their products with disinformation about the total cost of ownership of Linux solutions, but now it appears they can’t run fast enough, and rather than keep running, they have chosen to change their direction and not compete with Open Source, but to build their products to complement it.
Microsoft Operations Manager now has support for Linux based platforms, and Microsoft’s virtual machine software which they recently acquired will also have the ability to host Linux installations alongside Windows.
Ken Arnold writing in his blog on java.net thinks so. Ken believes that the benefits added to the language are not justified for the added complexity.
I must admit having read through some of the tutorials, at face value the concepts do not seem that complicated, but Ken has some examples on his site of some situations that seem pretty complicated to wrap your head around.
