The guys at WeLoveServers.com are having an anniversary sale. And a sale it is indeed! If someone knows of a better option please share it in the comments!

In order to use the sale, visit their site through my aff link: http://core.weloveservers.net/aff.php?aff=584 and after this click on any of the sale links below.

They’re offering the following two options:

• LEB 1GB – the link to the sale is here
• 
• LEB 2GB – link to the sale is here
  
  

So, basically, you get 1GB of RAM VPS for less than 19$ a year, and you get 2GB of RAM VPS for 48$ a year. Important thing to note is that I spoke with their sales representative and he told me that the price after this first year stays the same!?

Settings and additional options which you can set during the signup are:

You can buy additional RAM, storage, bandwidth, IP addresses, and even set a location of your server (TX, CA, NY, FL, UK). True, originally you don’t get any admin panel, but they offer a cPanel for 14.95$ a month if you really need one.

Anyways, I got myself one of the LEB 2GB and so far I’m very pleased with it and I have to say kudos to the customer service.

The basic panel looks like this:

We’ll see how this goes in the future – of which I’ll update you on this blog.

Happy testing!

My quesiton was if there is a way to serialize all form elements using serialize() function except the checkboxes?

The answer, by Simeon, was:

The .serialize() method can act on a jQuery object that has selected individual form elements, such as<input>, <textarea>, and <select>.

You could do this:

var s = $('#post-form').find('input, textarea, select').not(':checkbox').serialize()

Lately I’ve been playing at JavascriptBattle, which is

a fun and engaging web application intended to make artificial intelligence (AI) design accessible to all. Every day, your code will be pulled down from your “hero-starter” repository on Github. Your code (along with every other user’s code) will be run daily, behind the scenes, in our game engine.

Basically, you write JavaScript code for your hero in order to instruct him how to behave when for example his health drops to a certain level, or when enemies are close, etc. and then you participate in a daily battle. They have various stats, and as it turns out I’m currently on position #3 for average damage dealt, yay me!

Anyways, it’s cool so feel free to check it out and take me down from the pedestal :P. If you happen to like these “hacker games” then do checkout the one I made for my university project back in the old days .

I just competed (and finished! – I’m Hitman666) a Topcoder Scavanger Hunt.

Anyways, you have the instructions on how to play on the link above. I’ve really missed these kind of “hacker games”, like back in the days I was very active on hackits.de, but that site is long down now. Anyone playing similar games today, which you can recommend? I made my own for the project on university: http://nikola-breznjak.com/challenge/.

The questions were quite cool (no, no answers here, you’ll have to research it yourself):

• How many ‘Albert’ monkeys died in the US Space program?
• What was the original name of Nintendo’s Super Mario?
• How many female fighter pilots were there in the original Star Wars trilogy?
• How many different combinations of coins are possible for the US dollar?

My quesiton was:

I’m wondering how can I show (get) disk space usage and monthly bandwidth transfer on my website in the same way as it’s shown when I login to my cPanel account. Is there an api from cPanel for this or is this a general method to do so? I’m using PHP.

This answer, by user richsage, was:

cPanel/WHM has an API which offers access to both the elements you’re looking for. See the API docsfor more details. The bandwidth and disk usage modules in API 1 output HTML, however API 2 has anaccount summary method which will return the diskused parameter in the appropriate format (XML/JSON as requested).

Awesome short video about JavaScript event loop

One cool thing I didn’t know is that you can defer something right after the end of the stack. So for example the code below in the setTimeout function would print to console “done”, right after “hi” and “testing”:

console.log("hi");

setTimeout(function(){
    console.log("done");
}, 0);

console.log("testing");

I just read a great post on WebTools Weekly newsletter about how to convert a JavaScript switch statement into a function lookup. Here’s the full content from there, so be sure to check it out if you like it (it’s one newsletter a week, and no – I’m not affiliated with them in any way).

Because of the problems inherent in using JavaScript’s switch statement, many developers and reference guides will recommend avoiding switch constructs and instead using something called amethod lookup (also referred to as a lookup table or even dispatch table). Let’s convert a switchstatement to a method lookup, so we can see how this is done. Here’s our switch:

function doSomething(condition) {
  switch (condition) {
    case 'one':
      return 'one';
    break;

    case 'two':
      return 'two';
    break;

    case 'three':
      return 'three';
    break;

    default:
      return 'default';
    break;
  }
}

(JS Bin example)

All of this is inside a doSomething() function, with a condition passed in. The possible values are ‘cased’, to define the return value. This is cleaner than a messy if-else construct, but can we clean it up even more? Here’s basically the same thing in the form of a method lookup:

function doSomething (condition) {
  var stuff = {
    'one': function () {
      return 'one';
    },

    'two': function () {
      return 'two';
    },

    'three': function () {
      return 'three';
    }
  };

  if (typeof stuff[condition] !== 'function') {
    return 'default';
  }


  return stuff[condition]();
}

(JS Bin example)

In the demo, you can see four logs in the console, one for each valid condition and then another one to demonstrate the default condition when the argument doesn’t match one of the methods.

You can see why people like this technique. It’s clean, elegant, and seems a little more sophisticated without being more complex. I’ve only scratched the surface on this, so here are a few good resources to read up more on this subject:

My quesiton was:

This is the part of the code for one of the radio buttons:

$("#new").click(function(){
    if( $('#new').is(':checked') )
        $.jGrowl("You already have this option selected!", life: 1500});
    else
        changeOption(1);
});

Now, I understand that the else part will never run, because the radio button will be already checked on click event. What I’m wondering is, is there an event which would let me capture the state of the radio button (which is about to be clicked) and therefor determine if he is not yet clicked, and if so change the option to this newly selected one.

The answer, by JOPLOmacedo, was:

Use the mouseup event instead.

$("#new").mouseup(function(){if( $('#new').is(':checked'))
        $.jGrowl("You already have this option selected!", life:1500});else
        changeOption(1);});

The fiddle.

Edit
Even though the mouseup event works, it seems more logical to use the mousedown event. Here’s that fiddle.

My quesiton was:

I am searching for a substitute of the WebBrowser control in .NET which can handle HTTPS. This question is similar here on Stack Overflow, but none of these controls offer HTTPS.

btw, just to mention, I tried all these

GeckoFx – development stopped
Se7en – this is actually continued GeckoFx
Webkitdotnet – no one replying on forum

but none of them support HTTPS, so I’m kind of stuck here :/.

Also, to mention, WebBrowser control that comes with .NET framework works just fine with HTTPS, but the reason I can’t use it is because my app uses a lot of javascript that IE refuses to render, and for example Firefox (gecko engine) or Chrome (webkit) work just fine.

So, please if someone knows a good control that can do this (can be Webkit or Gecko wrapper, it doesn’t mind, as long as it’s not an IE wrapper).

This one I answered myself:

After long googling I finally ended up using the same as I was using before. So Webkit fromhttp://sourceforge.net/projects/webkitdotnet and I ended up purchasing a SSL certificate for my domain and now all is fine.
