  • (PHP) CurlParallel around the world

    About the project: https://github.com/danielecr/CurlParallel Selfing on the net this morning I discovered at least another interesting implementation of parallel fetch of network resource via PHP curl, that is https://github.com/dulao5/parallel-curl of https://github.com/dulao5, and is older than the one I take as starting point. Also that solution put focus on tasks to be managed not in curl by itself, thus giving more…

    What does is indexed by search engines? Of course the static pages are, but what about javascript originated content (i.e. AJAX)? By the end of 2011 Google indexs comments loaded via AJAX (i.e. Facebook, Disqus, …). https://developers.google.com/webmasters/ajax-crawling/docs/specification this is the last specs, that means (reading https://developers.google.com/webmasters/ajax-crawling/docs/html-snapshot) that the web server must provide a snapshot of the requested…

  • Debugging Javascript worker (and jQuery & workers howto)

    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. What happen in Chromium if you try to importScripts() jQuery? Simple: no error message. The problem is that jquery refer to window object…

  • following coursera courses

    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. I would endorse these courses because they make me feel really…

  • Parallelize PHP script (continued)

    The adventure continues.. 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:   require_once “sender.class.php”; class TestCurl implements iSenderConsumer { private $url_list = array(); public function __construct(Sender $sender) { // read…

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…

  • 3SUM algorithm tweak

    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…

  • Parallelize PHP script … or at least sort of it with curl parallel

    PHP is not a parallel capable programming language (someone would argue it is hard to state that PHP is a [anything]-capable programming language at all), but there are area where this could be parallelized some way. And these are the active waiting routine. The ideal scenario for a trival pseudo parallelization is a bundle of…
