Ajax File Uploading

You know that cool Drag and Drop file uploading they have in Gmail? You know, the one where you can drag a file from a folder onto a webpage and upload it?

Have you looked at the code? Looks complicated huh?

Well, thankfully, for any cool bit of JavaScript functionality out there, someone has created a plug in (most likely in jQuery, but not always...).

http://valums.com/ajax-upload/ is (as far as I can tell) a library agnostic JavaScript plug in which factors out all the hard work.

All you have to do is put in a "dummy" element on to which to hook (never end a sentence in a preposition) and then put in a small snippet of code to turn it into a file upload element


<div id="file-uploader">       
    <noscript>          
        <p>Please enable JavaScript to use file uploader.</p>
    </noscript>         
</div>


var uploader = new qq.FileUploader({
    // pass the dom node (ex. $(selector)[0] for jQuery users)
    element: document.getElementById('file-uploader'),
    // path to server-side upload script
    action: '/server/upload'
});

Obviously you need to include their library as well...

It has some common backend code to handle uploads as well (php, perl, cgi, java) but no Ruby. Come on guys! Get with it already! Hopefully they will read this and provide...

Master of my domain

Hi All, I just got myself a new domain ( http://www.skuunk.com ). The reason is that Blogspot.com is offering cheap domain via GoDaddy.com and I thought after having this nickname for nigh on 10 years it was time to buy the domain before someone else did (also I read somewhere that using blogspot.com in your domain is the equivalent of an aol.com or hotmail.com email address...shudder...). Of course I forgot that I would have to re-register my blog everywhere (which is taking ages) not to mention set up all my stats stuff again. *sigh*. It's a blogger's life... In any case, don't forget to bookmark the new address and to vote me up on Technorati !

Responsive Web Design

I wanted to go over Responsive Web Design using CSS. In the old days of web development, we had to code to common screen sizes (i.e. 800 X 600, 1024 X 768) and we patiently waited for people to upgrade their computers to have a decent amount of screen real estate so we could design things the way we really wanted. We also took on semi stretchy web layouts etc to expand and contract appropriately. Then about 2 or 3 years ago, Apple released this little device called an iPhone with a 320 X 480 resolution which took the world by storm and suddenly a lot of people were viewing your website on a tiny screen again... Anyways, as it can be difficult to design a site which looks good on 320 X 480 AND 1680 X 1050, we need to come up with some kind of solution. One way is to sniff the client and then use an appropriate stylesheet, but then you are mixing CSS with either JavaScript or server side programming and also potentially maintaining a list of appropriate clients and stylesheets. Also, you

Elixir - destructuring, function overloading and pattern matching

Why am I covering 3 Elixir topics at once? Well, perhaps it is to show you how the three are used together. Individually, any of these 3 are interesting, but combined, they provide you with a means of essentially getting rid of conditionals and spaghetti logic. Consider the following function. def greet_beatle(person) do case person.first_name do "John" -> "Hello John." "Paul" -> "Good day Paul." "George" -> "Georgie boy, how you doing?" "Ringo" -> "What a drummer!" _-> "You are not a Beatle, #{person.first_name}" end end Yeah, it basically works, but there is a big old case statement in there. If you wanted to do something more as well depending on the person, you could easily end up with some spaghetti logic. Let's see how we can simplify this a little. def greet_beatle(%{first_name: first_name}) do case first_name d
