Arch Linux is a lightweight distribution of Linux, designed to be user-oriented as opposed to beginner-friendly. Arch's guiding principals are self-education and experimentation, and there is little to no hand-holding when using it. Installing Arch Linux is a bit more complex than some of the more "friendly" distributions, but it won't take as long as you might think.

function chunkString(str, length) {
    return str.match(new RegExp('.{1,' + length + '}', 'g'));
}

fastest solution:

function chunkString(str, len) {
    var size = Math.ceil(str.length/len),
        ret  = new Array(size),
        offset, i;

    for (i = 0; i < size; i++) {
        offset  = i * len;
        ret[i] = str.substring(offset, offset + len);
    }

    return ret;
}

Here is an example on how to make a dynamic data collection form HTML form.

$('form.ajax').on("submit", function() {

    // get form attributes
    var that = $(this),
        url  = that.attr('action'),
        type = that.attr('method'),
        data = {};

    // get all name attributes
    that.find('[name]').each(function(index, value) {

        var that  = $(this),
            name  = that.attr('name'),
            value = that.val();

        // append all values form the name attributes
        data[name] = value;

    });

    // do the ajax request
    $.ajax({

        url: url,
        type: type,
        data: data,
        success: function(response) {
            console.log(response);
        }

    });

    // prevents the default behavior for submit
    return false;

});
