  PHP advisory file lock : flock

When we process a file in PHP, we may often need to acquire a lock so that other scripts cannot edit the same file at the same time. There is a flock() function in PHP which can help us lock the file we want to process. But there is one issue we should take care. Recently, ffb encountered one issue while he was trying to lock a file handle. The codes are below: $filename = "/tmp/lock.txt";      $fp = fopen($filename, "r+");   if (!$fp...

  Hey kids, just say NO to programming !

Cory Doctorow's latest talk 'The Coming War on General Purpose Computing' really puts things in perspective about life in the 21st century. This got me thinking more about functional programming languages and how they are related to the intentional limitation/crippling of turing machines by industry and government.

  Why we don’t hire .NET programmers

Skip my post and read this one instead.  It says the same thing, but less offensively.  (Or, rather, more offensively to Facebook and Google employees, less offensive to .NET developers, though the underlying message is the same.) Tuesday midnight edit: After >500 comments, >1000 tweets, and >1000 Facebook likes, I’m closing comments on this thread so we can all get back to work.  The very last comment takes the cake, however, and is a fitting close.  Th...

  How much money do you *really* need to start your company?

I keep hearing startup entrepreneurs tell me “We need funding. If we just had $XXXk of investment, we’d be killing it right now.” I press them with one question: what would you do with the money if you had it? Inevitably the question is met with a blank stare. Most of the time people haven’t thought about it. The answers that do come feel a little half-baked:“Buy a bunch of ad words to get people to our site – that’s all we need”“Build th...

Something about me being biased because I know and love it.  Usually say something about the competing technology with a back handed insult. Also if they are starting out I would recommend a language that enforces better OO (Object Orientated) practic...

  10 design flaws of JavaScript

JavaScript's design took only ten days. Moreover, the designer didn't want to design it initially, he just wanted to complete the task assigned by company. It is now a very powerful client side programming language used in almost all the websites. It's an excellent language, but it also has some flaws. 1.

It’s a game of pick two:Ship on timeShip with elaborate codeShip with a fantastic productAlmost always, you should pick the first and the last when you’re building software applications for users (if you’re building API’s or open source libraries for other developers, then it’s a different story). Too often I have seen de...
