[Solution] How to use this in setInterval and setTimeout problems inside objects

| No Comments »

Problem: One of the problems we find when using setInterval and setTimeout functions in javascript is how the special variable this is switched to the window object on the instance the function executes inside the interval.

Answer: Store the current object in a variable (for this example, the variable is called self) and use that variable for your interval’s function instead of this.

function foo()
this.init = function () {
var self = this;
this.interval = setInterval(function(){ self.update(); }, 1000); // this can be setTimeout

this.update = function () {

| No Comments »

You can’t use the root user when SSH’ing to WHM but what you can do is issue a SU command once you’ve logged in with another user which isn’t root. On some occassions, you may encounter a no permission error when doing this.

Problem: Help! I can’t seem to login as root in whm so I need to do a SU command instead but i’m getting a permission error!

Answer: In your whm panel, access Security Center -> Manage Wheel Group Users and you will be able to assign the username to the group that allows SU

And that’s the solution to your problem!

Super Tool: (Probably) the best SQLite Editor/IDE for web development and production use

| No Comments »

I really love SQLite. It’s lightweight and got a really small footprint. I use it as my database initially when i’m creating web applications(I then move to mySQL during production), the only issue I have is the lack of IDE for working with it. Of course there’s SQLite Administrator, i’m just not into the idea of installing a software especially with SQLite being small(I prefer not to cramp up as much software possible in my Windows).

This is where sqlite-manager comes along. It’s a 100kb plugin for Firefox(which also means cross compatibility with other OS), it’s a great complement to SQLite’s lightweight and small footprint. If you need to work with the database, you simply fire up sqlite-manager from the Tools menu.

That’s It!
