gnome-tweak-toolWith the advent of SSD's and mSATA we have a very less system boot time in the order of few seconds. That makes us impatient to click and open applications on our desktops! I recently switched to SSDs in the machines which I use, to make the systems responsive and end with impatience ;)

All my systems run Debian Jessie (8.0) and the systems on which GUI is enabled I have GNOME 3, specifically GNOME 3.14.x. There are some primary applications such as Terminal, Pidigin, Icedove and Iceweasel which I want to be ready as soon as I login to my machine enabled with GUI. This takes 4 clicks after login, but I wanted to have 2 steps only, ie., power on and login after which everything should be ready to get going. The way to go is some kind of session Application startup manager where I can instruct my machine to startup application as soon as I login. Looks like we had gnome-session-properties in the past for configuring the same in GNOME. It was recently removed.

I attended Ubuntu Developer Summit (UDS) last week in Copenhagen, Denmark. This is the first time I was attending such an event.

One of the best things happened was my interaction with Mark Shuttleworth during UDS. A picture talks a lot than words :)

OpenShift is a free cloud-based application platform from RedHat. Of late I caught an interest in Cloud Computing and wanted to try out different stuff. Though I did extensive reading on Eucalyptus, Amazon EC2, Ubuntu Cloud, etc. I wanted to try something hands on and chose to experiment with OpenShift. OpenShift has two flavors such as Express and Flex. Express is a shared application platform which supports Ruby, PHP, and Python applications. On the other hand flex is dedicated platform-as-a-service for Java and PHP applications which creates and provides management capabilities to operate on Amazon EC2 clouds (in future more cloud platforms will be added).

In work I wanted python2.7 for using some latest modules. I run Debian 6.0 ie., squeeze in my laptop, but python2.7 is available in Wheezy or Debian testing. In order to install python2.7 from the testing repository add the following in your sources.list file ie., /etc/apt/sources.list

deb http://mirror.cse.iitk.ac.in/debian/ testing main contrib

After adding the testing repository, do an update and then install python2.7 package as follows:

$ sudo aptitude update

$ sudo aptitude install python2.7

Gone are those days when we want to boot a downloaded ISO image from an USB stick, we need to perform lot of black box operation in order to put/align things in the USB stick so that it could be made bootable.

I didn't follow the Debian stuff for a long time though I use Debian in all my machines. Surprisingly last week we had the much awaited release of Debian 6.0 (squeeze) and I was over joyed on seeing that! I was longing for that.

With the new release of Debian 6.0 we need not do any special things in order to create a bootable USB stick of the Debian ISO. Just a plain 'dd' of the ISO will do the magic. For a long time in order to create a bootable USB stick we had to depend on tools like usb-creator both for Ubuntu or Debian, but now things are pretty easy and straight forward. I am not sure whether this works for Ubuntu yet, may be the next release 11.04 will have such a feature, but as of Debian 6.0 it works.

Often we find that our time zone is not what we expect to be in our Ubuntu/Debian boxes soon after installation. Specifically in Debian these days during installation we don't have fine grained control to choose our timezone like 'Asia/Kolkatta', instead we choose 'Eastern' and later decide to change it. In order to change the timezone in command line use the following command in your Ubuntu/Debian boxes,

# dpkg-reconfigure tzdata

The above brings up an ncurses based interface where you can have fine grained control of your timezone selection.
