It's really interesting to work on an extension for Chrome. However, sometimes it's a little bit difficult to debug. Especially when you work on a dev tools add-on (i.e. a new tab).

That's a super simple function for adding new css or javascript files in the current document. I didn't test it in all the browsers, because I'm using it in the chrome extension and I need only Chrome supported.

I just received a 250MB dump of a database and I needed to see what is it inside. As you may guess, PHPMyAdmin is not a good option in this case. I decided to use the command line.

I just found out that it is possible with pure javascript. It's supported in all the major browsers. Find more information here.

The replace method in JavaScript is pretty much the same as in the other languages. Replace part/s of a string with something else. However, there are some tricky moments and I wanted to write this article, because I met this problem several times in the past. Actually, very often I use my blog as a documentation for myself and this is one of those cases. Probably I'll be in the same situation after week or so and I'll just check here for the proper solution.

I'm currently working on a Google Chrome extension and I need to run a JavaScript in the context of the current page. The obvious choice for such a logic is the content script. However it is not so easy, because the content script has an access only to the DOM of the current page. It can't run global functions or use global objects.

Ok, that was a long journey. I took an already build project and I had to make some changes. It's a complex system involving flex applications, nodejs and a mobile site. Before to start making changes I had to setup the project and make it work on my local machine. I spend few days doing this. At the end I successfully compile the flex application and made the necessary corrections. I uploaded the new swf file and of course it didn't work.

I'm working on a chrome extension which accepts user text, work with it and output the result in a div. I used jQuery in the beginning, for several tasks, but later I decided to remove it and deal with pure javascript/DOM manipulations. The output div was filled by using innerHTML property and everything was ok. But, at some point, I sent few buttons to the user and he has to interact with them. However, once I update the div's content the event listeners are detached and the buttons became non-functional.

Really simple GET request from a flex based application. However it fails if GET parameters are passed.
