Technical News and tips from My learning

From long time, I've been looking out for a better regular expression for my web application. Every time, I adjust with some freely available expressions and complete the work. But this time, I've decided as not to compromise with what I get for free. And started writing my own expression. My email validator should justify all the following conditions.. 1) it should restrict the user name length between 4 to 50 characters length - {3,50} 2) it should allow dots, underscore, hyphen. But not as starting point - [-.\w] 3) it should allow numerical as well as alphabetic characters of both cases - [0-9a-zA-Z] 4) it should contain one dot after one @ 5) all the chars after @ should be at least 2 characters length and may be up to 20 characters consisting of alphanumeric with both cases After doing all kinds of R&D, concluded as below. Correct me if am mistaken. And extend if you have any further to add --------------------------------------------- ^(([0-9a-zA-Z]([-.\w]*[...

Now-a-days am attending interviews for my next job. Most of the calls are for the Architect position. While preparing for these, realized few responsibilities and activities that were part of my previous roles. And they are the main theme of this post. As mentioned in the post title, questions that comes to every developer's mind is.. who is an Architect? who can become an Architect? what an Architect do? what are the prerequisites for an individual to become as an Architect? etc., Having mentioned all such questions, , would like to make things clear, out of my experience. Readers has every right to deny or challenge my understanding. First of all, an Architect is like soul in the human body which you can never see but always experience the existence. This definition is totally true in small sized organizations. Because an Architect plays every role that is part of any implementation with in small scale industries. Architects are expected to be technically sound and funct...

Though the runtime that is released on 28th March 2008 is not related to .NET, but I see a huge breakthrough from Microsoft towards the runtime engine growth as well as the next generation runtime engines. Infact, if they could do it with MS-Access, it is not a big deal for Microsoft to introduce such similar runtime for .NET CLR as well. Hopefully, in the near future we would see the same kind of runtime for .NET as well, leveraging the .NET languages to the next level of localisation. Honestly many a kind of the following questions are cooking in my mind... help me if you have any clue for any of the following Do we really require a localised version as such? What benefit that a localised runtime will add feather to the application? Rather confirmed, am now more confused... who will help me..
