Big news for developers out there: Google has just announced the release of a new, open sourced programming language called Go. The company says that Go is experimental, and that it combines the performance and security benefits associated with using a compiled language like C++ with the speed of a dynamic language like Python. Go’s official mascot is Gordon the gopher. Read more ……

Go is a compiled, garbage-collected, concurrent programming language developed by Google.

The initial design of Go was started in September 2007 by Robert Griesemer, Rob Pike and Ken Thompson,building on previous work related to the Inferno operating system.Go was officially announced in November 2009, with implementations released for the Linux and Mac OS X platforms.

The syntax of Go is close to that of C except for the type declarations; other syntactical differences are the missing parentheses around for and if expressions. It is designed for exceptionally fast compilation times, even on modest hardware. The language requires garbage collection. Certain concurrency-related structural conventions of Go (channels and alternative channel inputs) are borrowed from Tony Hoare’s CSP, but many (such as Edsger Dijkstra’s guarded commands) are omitted. Unlike previous concurrent programming languages such as occam or Limbo, Go does not provide any in-built notion of safe or verifiable concurrency. Go also has some features of the Pi calculus such as channel passing.

Features not included in Go are exception handling, type inheritance, generic programming, assertions, and method overloading. Of these, the Go authors express an openness to generic programming, explicitly argue against assertions, while defending the choice to omit type inheritance on efficiency grounds. Unlike Java, maps (also known as hashes or dictionaries) are an intrinsic part of the language, as are strings.

Visibility of functions outside of their defining file is defined implicitly according to the capitalization of their identifier, in contrast to C, where an explicit static keyword is used. Source : Wikipedia

New Web Development Technologies: Beyond HTML

KRISARU.com — Sat, 04 Apr 2009 04:03:49 +0000

After stagnating for quite some time, Web powering technologies are now experiencing rapid development. CSS (Cascading Style Sheets) is just the first wave, and it’s already giving way to more robust technologies like DHTML, LAMP, XML (read An Introduction to the Extensible Markup Language for more information on this technology), and AJAX. Attempting to stay current on these technologies can be both time consuming and expensive, which raises the question: should you stick with what you have, or take the plunge and incorporate these advanced techniques?

The answer depends on the kind of site you have and what your users expect to get from it. Will incorporating one or more of these technologies actually improve the usability of your site? If you’re merely attracted to the cosmetic overhaul they would provide, you may want to reconsider. Also worth considering are implementation time and costs. Are you willing (or can you afford to pay somebody) to implement the new technology? When all is said and done, engineering can be much more expensive than site design, and can also necessitate ongoing maintenance if your site changes regularly. Read more on Web Powering Technologies.
