Installing Sphinx Search on Basic 64-bit Amazon...
This is a simple step by step in installing Sphinx Search on Basic 64-bit Amazon Linux AMI. This is applicable to 32-bit too. This installation is very bare, starting from zero installation at all.
The conditions I wanted to meet:
Using the very latest Sphinx Search documents. And when I say latest, I mean it. I am using Sphinx Search trunk, because I need the RealTime Indexing (RT Index) and...

Hey guys, I need your point of view on this. So I have this query, which can take up to 17 (Seventeen!) tables into one query. I have been using Sphinx a lot for searches, and luckily, since Sphinx 1.10-beta, we have this attribute called sql_attr_string. What this attribute does is store the value for retrieval at Sphinx. So this is what I get (below is a sphinx index):

Business models should be based on customer demand and an understanding of what is technically feasible - not a desire to maintain existing models or cash flows. In other words, you need to adapt the map to the terrain - you cannot change the terrain to suit the map.
Object runs faster than array!
Amazing new finding again. Now take a look at this:
foreach ($query->result_array() as $page):
$links .= '<a href="'.site_url($page['uri']).'">';
$links .= ucwords($page['title']).'</a><br />';

compared to this:

Foreach Loop Optimization
This is crazy! I’ve just found out that:
$pages = $query->result_array();
foreach ($pages as $page):
is a lot faster than:
foreach ($query->result_array() as $page):
Crazy! It happens that $query->result_array() is called multiple times if you put it inside the foreach(). I need to learn more…

Trouble in opening CSV formats on Microsoft Excel
When you open a CSV file with Excel, they will check your regional settings, and sometimes depending on your regional setting, they will use comma or semicolon. To let Excel know that you only want one of those type of separators, you should generate your CSV like this:
sep=, “col1”,”col2”,”col3”
… or this:

Swiftmailer bug simple fix
There’s a major bug in Swiftmailer, where sometimes your email returns 0 bytes attachment, or broken html email, or broken plaintext email in Yahoo? Well the cause of this is that Swiftmailer wrongly sends header and body. They forgot to separate the two.

“measure revenue, not conversion rate”

Apakah over-budget dan over-schedule dosa besar?
Terkadang kita menganggap jika jika kita membuat sesuatu melewati budget atau melewati schedule, maka itu sudah menjadi dosa besar.
