  40+ Techniques to enhance your php code


1. Do not use relative paths , instead define a ROOT path Its quite common to see such lines : 1require_once('../../lib/some_class.php'); This approach has many drawbacks : It first searches for directories specified in the include paths of php , then looks from the current directory. So many directories are checked. When a script is included by another script in a different directory , its base directory changes to that of the including script. Another issue , is that when a script is being ru...

  Software philosophy: Release early, release often vs polished releases


Release early, release often is a philosophy where you release the product as soon as possible and rapidly iterate it to perfection by listening to your customers. A polished release, on the other hand is where your product, in its initial version is solid, lacks obvious bugs and has just enough features to satisfy a majority of your consumers. Most software companies adopt either one of this and that choice is not superficial. In fact, it roots down to the heart of the company’s ideolo...

  The most stupid C bug ever


I have been programming for a number of years already. I have seen others introduce bugs, and I have also introduced (and solved!) many bugs while coding. Off-by-one, buffer-overflow, treating pointers as pointees, different behaviors or the same function (this is specially true for cross-platform applications), race conditions, deadlocks, threading issues. I think I have seen quite a few of the typical issues. Yet recently I lost a lot of time to what I would call the most stupid C bug in ...

  Optimization Tricks used by the Lockless Memory Allocator


With the releasing of the Lockless Memory Allocator under the GPL version 3.0 license, we can now discuss more of the optimization tricks used inside it. Many of these are things you wouldn't want to use in normal code. However, when speed is the ultimate goal, sometimes we need to break a few rules and use code that is a little sneaky.The SlabA slab is a well-known technique for allocating fixed size objects. For a given object size, a chunk of memory is divided up into smaller regions of that ...

  My life as a freelancer


In the summer of 2006 a work buddy, George, has told me that I could make some extra money programming on a site named Rent A Coder. I’ve signed up the same day. After losing some time on a project that never started I lost my interest in “coding for money”. I almost forgot about RAC.Fast-forward two years, I was a PhD student at a small North American University with a student visa and … nothing else in my pockets. For a few months I was able to make a living from a scholarship unt...

  Host multiple websites in Wamp


I have decided to start playing around with the Zend Framework. I have a web host (of course) however sometimes when developing I find it is easier and faster to use a local web server, with all the bells and whistles. WAMP, LAMP (this link is ubuntu specific, but any linux distribution should have easy HowTo guide for installing the LAMP software stack), MAMP, all provide the basic environment for beginning web development, and some have nice little GUIs to help you con...

Mark Lucovsky, famous for building Windows NT and watching Steve Ballmer throw a chair.Mark Lucovsky was the other man in the room when Steve Ballmer threw his chair and called Eric Schmidt a “fucking pussy.”Yes, the story is true. At least according to Lucovsky. Microsoft calls it a “gross exaggeration,” but Lucovsky says that when he walked into Ballmer’s office and told the Microsoft CEO he was leaving the company for Google, Ballmer picked up his chair and chucked it acro...

  First steps with Scala, say goodbye to bash scripts…


Those who know me are aware that I’ve been following play framework, and actively taking part of it’s community, for a couple of years. Playframework 2.0 is right around the corner, and it’s core is programmed in Scala, so it’s a wonderful opportunity to give this object-oriented / functional hybrid beast a try… Like many others, I will pick a very simple script to give my first steps… Finding an excuse to give Scala a try With a couple of friends we are on the way to translate play...
