Some reasons for which to use Whatsapp as your default messaging client.

I've been using Whatsapp messaging client on my phone intensively for about half a year now, and I've been really satisfied with it. Or at least, it's been working perfectly for me until now (Galaxy Nexus on Jelly Bean now), even though there are some who report serious issues with it. For those who did not use it until now, the main idea is that it is a lightweight messaging client which works over the internet (WiFi or mobile network).

I really recommend it because it is very popular (so there should be a lot of users to speak to), uses a very small amount of battery, it is very fast, and uses a ridiculously reduced amount of data. I've sent about 3700 messages since I installed Jelly Bean (very recently) and it used only 1.5 MB, which is really negligible, considering that I have a 750MB data plan and I am a lot of time in areas where WiFi is available free of charge.

But here is the most important feature: based on the mobile phone number, it detects whether the contacts from your address book have Whatsapp installed or not, and it will display those who have it. For this purpose, you'll have to give your phone number when you first run the application. And as you had probably figured out already, you are going to be in tho places, with two different accounts, in the case that you have two phones and you want it installed on both of them. For this reason (the necessity of having a mobile phone number), Whatsapp can't run and was not designed to be used on computers. So no, there's no PC/Mac version, and probably, there will never be one.

Whatsapp is available for the following platforms (click the links for download):

• Android (free for the first year);
• iOS ($0.99);
• BlackBerry
• Nokia phones (Nokia Series 40, Symbian and Windows Phone);

Virtual keyboard search feature, by Google.

Google added a virtual keyboard next to the search bar ( ) for their search engine, which can be used in order to type what you want to search without a keyboard, or if you're using a physical keyboard and this feature is opened, you will see the corresponding keys on this script while you're typing. It is not available for English searches, but for most other languages. It looks something like this below (mine is in Romanian):

Transform your iPhone into a flash drive.

Managing files between iPhone and PC/Mac has never been easy, since these tasks need iTunes, which we all know that is not an expert. However, there are available some applications for iPhone that can transform it into a wireless flash drive.

The application I'm going to talk about is named "Discovery". This works only if the computer and the iPhone are connected on the same Wi-Fi. You can download and upload various content between your computer and your iPhone, without need the use of any cable. You can view documents, video, music, pictures and more.

It has a function named "Nearby", which will detect any iPhone that is around and has Discovery service running, allowing you to share files with them. After launch, the application will tell you what address to type into your browser in order to access the iPhone. It's compatible with any OS. And the best part, it's FREE. (commercial version also available, but the only difference is that it removes advertisement)

Search it in App Store: "Discovery".

Google Chrome OS on VirtualBox.

Even if Google Chrome OS is still not available for complete installation on regular computers, it can still be ran on virtual machines. A good and free virtual machine is called VirtualBox, and it can be downloaded from the official site here. Everyone should be able to install and use VirtualBox, since it is very simple and efficient.

By the way, you should start downloading the image of Chrome OS from here, while I'll tell you what else you need to know. The image archivated, so if you are under Windows I would recommend you to download and install WinRar, and when the image download is completed, you can unarchive (or dearchive, or how it should be told) it. Leave the image as it is. In the VirtualBox, Google Chrome OS should be set as a Linux operating system, then as version Ubuntu. Everything you need to do is simple, and for additional informations you can either visit this link:

http://www.techcrunch.com/2009/11/19/guide-install-google-chrome-os/, or you can leave a comment and i'll help you. You will have to login into OS with your Gmail username and password.

I've tested it on a Macbook with 2 GB of RAM and Intel Core2 Duo processor at 2.00 GHz, and it worked fine.

Attention!! Do not allocate to VirtualBox more than your current free RAM memory, otherwise the computer can become unstable or it can stop responding !! (it would be good if you save your work before starting the virtual machine)

Thanks to WebUpd8 for everything.
