Hello!

This is a short announcement post to tell you that I've created an account on Codepen. Codepen is a site that lets you experiment with HTML, CSS and Javascript (or their compiled variants) and share your creations with the world.

I've already created something on there - I'll be blogging about that soon.

Right now though I'm rather ill though, so please don't be disappointed if I don't post right away (although I'll certainly try to get it out asap).

Here's a link to my Codepen profile page.

Hello again!

I now have a reddit account. You can find it here: https://www.reddit.com/user/starbeamrainbowlabs

I have attempted the latest Daily Programmer challenge.

This time I have written it in javascript. The challenge was to validate an ISBN-10 number. To validate an ISBN-10 number, you add 10 times the first number to 9 times the second number to 8 times the third number and so on. This total should leave no remainder when divided by 11. In addition, the letter X stands for a value of 10.

Here is my solution:

function validate_isbn(isbn) {
    var i = 10,
        tot = isbn.replace(/-/g, "").split("").reduce(function (total, char) {
            if (char.toLowerCase() == "x")
                total += i * 10;
            else
                total += i * parseInt(char);
            i--;
            return total;
        }, 0);

    if (tot % 11 === 0)
        return true;
    else
        return false;
}

I minified it by hand too:

function validate_isbn(a){var i = 10;if(a.replace(/-/g,"").split("").reduce(function(b, c){if(c.toLowerCase()=="x")b+=i*10;else b+=i* parseInt(c);i--;return b;},0)%11==0)return true;else return false;}

I should probably attempt the next challenge in C♯ so that I keep practising it.

I now have a twitter account!

You can find it here.

It will be mostly automated, once I rewrite the blog posting system. Until then I will post manually.

I plan to have the blog automatically tweet about new blog posts, but I will have to build some kind of system that will be able to tell the difference between new and updated posts first, since I make usually make several corrections to each my blog posts once I have posted them.

I now have a github account. I will be using it to house programming projects, most of which are / will be released on this website.

I currently have 1 repository, which holds something that will be released here soon.
