Split your Browser Window like in emacs, or vim

Recently, I was looking at source code over the internet and had trouble looking at the entire code in one window without having to create another just to see the entire content of that page.

Hoping there was a “split window” add-on for Firefox out there similar to emacs or vim, I began my search and found Split Browser. Split Browser allows you to split your browser window however you like. You can split your browser in order to see more of the current page without the need of having to open a new window which I thought was great. A preview of it in action is below.

Creating a factorial function

1. C++ Recursion
2. C++ Recursion – Summation

Example:

factorial(5);

Result:

120

Iterative version of a function that calculates the factorial

---

To understand how to calculate the factorial using recursion, let’s write a simple algorithm that will do it for us using iteration.

int factorial(int n) {

     //Initial value for the final value is 1
     int factorial = 1;
     
     for ( int i = 2; i < = n; i++ ) {
          factorial = factorial * n;
     }

     return factorial;
}

Google Chrome OS was finally revealed this morning. So what is it? Google Chrome OS is focused on making your OS revolve around an internet browser since we spend 90% of our time on the internet anyway. With that, all your files, music, applications, and whatnot will be accessed using the internet, thus eliminating the need to store anything on your PC. So where is everything going to be? In the cloud.

Impressions on Google Chrome OS

I don’t know about this, but I certainly don’t have access to a reliable internet connection 24/7 with my mobile laptop. Does that mean I wouldn’t have any access to any of my files when I’m on the road? Then, this would be useless for me in that situation.

Also, so far it only seems like its going to support a very small number of applications since its geared towards people who only use a computer for accessing the internet. What about developers? I use a lot of tools to program in various languages and platforms. Will this be suitable for me? So far, it looks like it won’t.

Either way, it looks quite interesting naturally being a Google product, but doesn’t necessarily look like something I’d switch over to yet. Maybe once it matures and comes closer to beta, I’ll probably be interested, but until they stick with having everything in the cloud and having a very specific functionality, I just don’t know.

Download Google Chrome OS Virtual Machine

Update: Believe it or not, you can actually download a build of the disk image. Check out Download the Google Chrome OS Virtual Machine from Geeklad.

Remember the Google Wave Invitations post? Well, people asked, and 7 lucky winners will get an invitation! (I randomly picked 7 people using a random number generator).

Congratulations!!!

I recently got invited to the invite-only Google Wave and fortunately for you, I also got invitations to give out to you. But…wait a minute? What is Google Wave?

What is Google Wave?

According to their About Google Wave, Google Wave is an online tool for real-time communication and collaboration. It can be used to discuss and collaborate texts, photos, videos, maps, and so much more.

Google Wave Invitations

So how do I get one? Post a comment on why you should have an invitation in the comments and make sure you post your e-mail address correctly. Then, in a day or so, I’ll announce who gets an invitation. Simple as that.
