Installed Ubuntu Linux

Yesterday I installed Ubuntu Linux on an old Samsung V25 laptop. The installation process was pretty smooth, except for the blinking screen. The screen resolution selector did not show the resolution of my machine (1024x768), so I selected the closest match of 1200x800. Rest was smooth, Ubuntu installed properly with a few post installation hiccups.
- The GUI started with a screen resolution of 640x480. The screen resolution preferences box from the admin menu did not have any other option. That was a let down. However after some Googling I found out that I could get the original resolution of my monitor by tweaking the refresh rates in /etc/X11/xorg.conf. I added two lines in the 'monitor' section -
HorizSync 31,5-48,5
VertRefresh 40-70
This did the trick. The resolution was perfect.

-This version 5.10 had proper ACPI support, which the previous version 5.04 lacked. However when I unplugged the power cable the icon in the tool bar took about 5-10 seconds to change to battery power. The screen dimmed immediately, which was good. The battery icon once displayed, showed the proper available battery power.

-The mouse moved too fast. I reduced the acceleration and increased the sensitivity slightly to make the mouse move at a speed, that I was comfortable with.

Fuctional Programming Principles in Scala - Getting Started

Sometime back I registered for the Functional Programming Principles in Scala , on Coursera. I have been meaning to learn Scala from a while, but have been putting it on the back burner because of other commitments. But when I saw this course being offered by Martin Odersky, on Coursera , I just had to enroll in it. This course is a 7 week course. I will blog my learning experience and notes here for the next seven weeks (well actually six, since the course started on Sept 18th). The first step was to install the required tools: JDK - Since this is my work machine, I already have a couple of JDK's installed SBT - SBT is the Scala Build Tool. Even though I have not looked into it in detail, it seems like a replacement for Maven. I am sure we will use it for several things, however upto now I only know about two uses for it - to submit assignments (which must be a feature added by the course team), and to start the Scala console. Installed sbt from here , and added the path

Five Reasons Why Your Product Needs an Awesome User Guide

Photo Credit: Peter Merholz ( Creative Commons 2.0 SA License ) A user guide is essentially a book-length document containing instructions for installing, using or troubleshooting a hardware or software product. A user guide can be very brief - for example, only 10 or 20 pages or it can be a full-length book of 200 pages or more. -- prismnet.com As engineers, we give a lot of importance to product design, architecture, code quality, and UX. However, when it comes to the user manual, we often only manage to pay lip service. This is not good. A usable manual is as important as usable software because it is the first line of help for the user and the first line of customer service for the organization. Any organization that prides itself on great customer service must have an awesome user manual for the product. In the spirit of listicles - here are at least five reasons why you should have an awesome user manual! Enhance User Satisfaction In my fourteen years as a

Inheritance vs. composition depending on how much is same and how much differs

I am reading the excellent Django book right now. In the 4th chapter on Django templates , there is an example of includes and inheritance in Django templates. Without going into details about Django templates, the include is very similar to composition where we can include the text of another template for evaluation. Inheritance in Django templates works in a way similar to object inheritance. Django templates can specify certain blocks which can be redefined in subtemplates. The subtemplates use the rest of the parent template as is. Now we have all learned that inheritance is used when we have a is-a relationship between classes, and composition is used when we have a contains-a relationship. This is absolutely right, but while reading about Django templates, I just realized another pattern in these relationships. This is really simple and perhaps many of you may have already have had this insight... We use inheritance when we want to allow reuse of the bulk of one object in other
