Even if I finally found Web workers:error and debugging article that explains it well and exensively, I just had to report that developing with Firefox is still the right choice in most case.

I am updating my knowledge by following some courses on coursera.org, that is: https://www.coursera.org/course/compneuro (computational neuroscience) and https://www.coursera.org/course/eqp (exploring quantum physics). I found both require that kind of math called statistic, or something like that, and summing vector of values, multidimensional calculus ... very interesting and mind opening.

Some more commits to repository in https://github.com/danielecr/CurlParallel, the goal is to parallelize a php application as much as possible in the task of network I/O concerns. This is the test class in the rep:

I refer to http://api-first.com/ . The idea is, after wrote the stories needed to define interaction, and thus functions, of the system we are going to implement, the next step is to define an api, then proceed with API definition, then implement backend, frontend, and cycle this way redefining stories (or adding), refining api, change frontend and backend. This is not water fall, is just a sequence to follow in the cycle, something like rithm keeper (metronome?), of development process.

http://en.wikipedia.org/wiki/3SUM this is the algorithm. I just thought that I can start from the middle, the rationale is that I have the work done not to be due.

I wrote down the value of an example and try to iterate on the outer cycle starting from middle (max value + min value) then down to the lower value, what happen (hand running iterations) is that I never have to consider the excluded item in the preceeding iteration (outer iteration), thus I added a start point keeper array.

Using a model with nested observable array I did not know how to refer to self in a event handler (click) on a element in a cycle on that observableArray ...

enlight me on use of static methods and relation with TDD, what I learned so far is that is better to define a collection class implementing a collection interface, which has method that operate on collection of object, if this is the intend of the use of static methods. Example:

First of all, I have to pay some money to take it, so I tried to get information about this exam.

I just passed Zend Certification exam for PHP 5.3 . It means I have paid Zend, first of all.

They gave me a printed paper (phisical paper) with instruction on what I can do.

It says I can use Zend Certified Engineer icon found in http://www.zend.com/en/services/certification/zce-logo on my CV and site. This is the one that apply to me:

I would talk about a pattern whose name I fail to know before, giving it the name of multi-singleton.

Registry pattern

I read about it in PHP 5 certification study guide from php|architect's series. This is the example given:
