Apple's new programming language modernizes iOS development by synthesizing great ideas invented elsewhere

Hot or not? From the Web to the motherboard to the training ground, get the scoop on what's in and what's out in app dev.
The tech world has always been long on power and short on thinking about the ramifications of this power. If it can be built, there will always be someone who will build it without contemplating a safer, saner way of doing so, let alone whether the technology should even be built in the first place. The software gets written. Who cares where and how it's used? That's a task for somebody in some corner office.
Slow startup times, null pointers, security flaws -- Java's ongoing success leaves plenty to complain about
If hitting a target is hard and hitting a moving target is even harder, then creating a new hit technology is next to impossible because the shape and nature of the target morphs as it moves. Think of building a swish new laptop just as laptops are heading out of favor, or a must-have mobile app just as smartphones plateau, or a dynamite tablet experience just as the wearable future takes hold.
Cloud-based back ends for mobile applications combine key services with varying degrees of complexity
Programmers love to sneer at the world of fashion where trends blow through like breezes. Skirt lengths rise and fall, pigments come and go, ties get fatter, then thinner. But in the world of technology, rigor, science, math, and precision rule over fad.
Making the most of this powerful MapReduce platform means mastering a vibrant ecosystem of quickly evolving code
Coding mobile apps becomes faster and easier with these revolutionary tools and Cloud services
Before turning to the world of Cloud computing, let's pause to remember the crazy days of the 1970s when the science of the assembly line wasn't well-understood and consumers discovered that each purchase was something of a gamble.
Rigorous input testing, passwords, encryption - security is a feature no programmer can afford to overlook.
Sun Microystems, which announced Sun Cloud in March, is taking a different tack than the Java clouds from Google, Aptana, and Stax because it wants to be more than just a Java provider. The new cloud will create new clusters of machines from any disk image, including some of the most popular versions of Linux and Solaris. Java, of course, will be found in most of these images, but you don't need to use it if you want to, say, run some emulated version of Cobol on a version of Puppy Linux. Unless Sun Cloud is interrupted by Oracle's acquisition, it should be available in a few months.
Who wouldn't want to live in a "cloud"? The term is a perfect marketing buzzword for the server industry, heralding images of a gauzy, sunlit realm that moves effortlessly across the sky. There are no suits or ties in this world, just toga-clad Greek gods who do as they please and punish at whim, hurling real lightning bolts and not merely sarcastic IMs. The marketing folks know how to play to the dreams of server farm admins who spend all day in overgrown shell scripts and impenetrable acronyms.
Google App Engine is meant for dreams like these. You write a bit of code in Python, customise some HTML, and bingo, you've got your database-backed dynamic Web site up and running in a few short minutes. The magic comes when the world starts flocking to your Web application, and Google's cloud of computers quickly adapts to the load, handling everything the public demands. There's no need for you to buy servers, load balancers, or special DNS tables. Google's application cloud handles all of the grungy deployment headaches.
