Why mailchimp-mandrill driving me nuts?

By |2018-08-11T23:02:08+00:00August 11th, 2018|Categories: Programming|Tags: , , |

I found Mandrill and their template engine which you can set it to use Handlebars.js is very powerful and fit my needs pretty well. Because Mailchimp templates design editor is robust and easy to use, we started to build the templates in [...]

Some of them want to Interrupt you, Some of them want to be Interrupted

By |2018-10-07T20:55:13+00:00August 11th, 2018|Categories: Productivity|Tags: , |

Interruptions at work can be maddening. Researchers at the University of California, Irvine, found after careful observation that the typical office worker is interrupted or switches tasks, on average, every three minutes and five seconds. And it can take 23 minutes and 15 seconds just to get back to where they left off. Jonathan Spira, author of “Overload! How Too Much Information Is Hazardous To Your Organization,” estimates that interruptions and information overload eat up 28 billion wasted hours a year, at a loss of almost $1 trillion to the U.S. economy.   Quite few years since this [...]

Organize JavaScript and jQuery events – DOM-ready execution

By |2012-04-19T17:32:31+00:00April 19th, 2012|Categories: Programming|Tags: , |

In complex websites javascript and jquery events can conflict with each other, especially if you are using the same javascript files for different website pages. There are many techniques to solve this issue, and I found a good solution by following these articles: Automate firing of onload events Markup-based unobtrusive comprehensive DOM-ready execution Extending Paul Irish’s comprehensive DOM-ready execution But while using this technique I faced an issue, I wanted to call more than one init function on the same page load, for example if I have my page as sections: header, login popup, inner form, footer.

Simplest menu using CSS

By |2018-06-19T14:15:23+00:00October 3rd, 2011|Categories: Technical|Tags: , |

Many web designers I met had problems while  creating menus, specially which contains nested sub menus. In some cases it is a real pain, but in most of cases it is simple, and the problem come when the designer start to implement the simple menu the hard wrong way, it will take ages from him to implement a simple menu while it just need few lines of css code. Also he may think it can’t be done without javascript and jquery. Try to think simple while writing your next menu and may be you will need my code as a starting [...]

By |2011-06-29T17:36:36+00:00June 29th, 2011|Categories: Technical|Tags: , , |

While reviewing some code, I found someone calling jQuery Ajax like this: $.ajax({       type: "POST",       url: "/AddPost",       data:  "postText="+ PostText ,       dataType: "json",       success: function (status) {        }}); //$.ajax({ And as you see in the previous code, it is sending the data using this line: data: "postText="+ PostText , This is like a query string style, this will work well but image the user inserted a special char in PostText, such as ?? you will get on the server un expected value “"jQuery15107041011152323335_1309357585354"” So never use this style while dealing with Ajax calls, you need to post it in JSON [...]
