What I love in Outlook 2013

I installed Microsoft Office 2013 few weeks ago. So in Office as usual there are few enhancement and new things. But I should write a blog post about what I love in Office 2013. It is about Outlook. In Outlook they have added new feature to text area which makes us feel that we are typing faster. When we type cursor is not jumping it is wiping through the text.

That feature is awesome one. I hope that will be implemented in Word and other text boxes in Windows in future. Or at least give a option to users to Enable/Disable it. I really don't bother about those effects in software. But this one I can't ignore. I love it. I don't use G mail because of this. I use Outlook 2013.

And if I don't mention about LinkedIn integration, that's not cool. So they have given a facility to connect LinkedIn profile with Outlook. It syncs all the contacts from LinkedIn and use their faces on contacts. I really love it too.

Installing RedHat Enterprise Linux from USB Drive

Recently I downloaded Red Hat Enterprise Linux 6.0 to install on my home server. And I'm a person who haven't used Optical Drive for ages. On my laptop even DVD Drive doesn't work properly. So every time I use USB Drive (Pen Drive) to install any operating system because my server doesn't have a optical drive. Although I call it a server it is just a machine without CD Rom and blah blah.

Then as usually I wanted to make Red Hat ISO bootable. Then I used UNetBootin to make my USB drive bootable. But I got mounting error in installation when I was going to format hard drive. So it never happened with Ubuntu for me. Then I searched here and there to find a method to install RHEL. Then I found a link to iso2usb. It worked bit far away from that place. But it just installed minimal Linux server with out any GUI. There was no any option for it on Installation Wizard. Installation Wizard was GUI one although.

The I used fedora live usb create. It didn't work properly. Then I copied all the contents of DVD into my server machine and added a repo entry for yum to DVD packages. :)

NoSQL Discipline

Long time ago there were very few popular databases. Because starting a DBMS was not easy with relational database model. But now with NoSQL database management systems are getting cloned. Numbers of database management systems are growing exponentially.

Now the fashion is, if you are fed up with DBMS which is existing you can write a new one and be a master of it. No matter what ever it is. It may be just a API to reading from or writing to text file. But to be frank there are few good NoSQL databases. But most of them are clones. Clones give nothing to the industry, nothing to the growth of data science.

Data is something valuable to everyone. All of our IT professionals depend on Data. So it is not a joke to play with those useless NoSQL databases. :)

Did you know about JuJu?

Juju is a new solution for Developer's to configure their development environments very very faster than it was. Developers don't need to be a expert on each and every service and how to configure each and service. Juju has distilled knowledge on each and every product like MongoDB, Cassandra or Hadoop. Creating environment's (linux) becomes more and more easier with juju.

Juju is still in development and not good for real production. But as I feel it is going to play a big role on the industry like Hadoop. Most of the businesses are looking into DevOps model. So juju helps DevOps as well. 

Juju is another work from african language like Ubuntu. It means magic. Juju is magic. Actually magic is going to happen! Enjoy JuJu!

Are you looking to move to Ubuntu?

When you are going to move from Windows to Ubuntu you should be aware about versions to move. So If you are looking to move to Ubuntu you should select LTS (Long Term Support) version. Currently latest Ubuntu LTS version is 12.04. Most of the times LTSs are more stable than other versions.
Also now Firefox is getting other side. So you should install Google-Chrome. Otherwise with Firefox you will fed-up with Ubuntu. It's better if you can use Google Docs more than Libre office. Because Personally I don't like to use LibreOffice. 
Go Ubuntu!
