In code reviews, people sit down to review someone’s code. Everyone has an opinion but not everyone is going to be working with the code on a daily basis. At the time, everyone seems to be involved in the process but there is no vested interest. They are just looking at some code and asking themselves "does this code look good and is it correct?". It’s a very passive standpoint. On the other hand, pair programmers are completely invested (committed?) in the task at hand. They immediately are using the code they are writing together and collaborating their thoughts on design, code layout, etc. Both programmers are taking on an active role and are emotionally invested in the task at hand because they are attacking the same problem together.

Couple of days ago I installed Ubuntu 8.10 on my Dell Latitude D830 laptop and network management applet worked well with my home wireless network where there are no security. But when I was back to office default network management applet comes with Ubuntu began to connect and disconnet my wireless connection time to time(after every 1-2 minutes). My office network connection is secured and I think that is the cause for malfunctioning network management applet. After Googling a bit I found the 'wicd' network manager. I removed the nm-applet and installed 'wicd'. Until now 'wicd' ddin't give me any problems. I think 'wicd' is a better alternative for default Ubuntu 8.10 network manager. But 'wicd' doesn't have somefeatures available in the Ubuntu's default network management applet.

For a lot of people, the term “Web 2.0,” ceased to mean anything real a long a time ago. For some, it never really meant anything to begin with. As someone who writes about the so-called second version of the web for a living, I think I’ve held onto the Web 2.0 term as long as I could. But today, “Web 2.0? has officially jumped the shark for me. That doesn’t mean I’ll stop using it — as a blanket term to describe the industry that I write about it can be helpful — but I have to admit that it has now become somewhat of a parody.

A class represents the code to be executed, whereas data represents the state associated with that code. State can change; code generally does not. When we associate a particular state to a class, we have an instance of that class. So different instances of the same class can have different state, but all refer to the same code. In Java, a class will usually have its code contained in a .class file, though there are exceptions. Nevertheless, in the Java runtime, each and every class will have its code also available in the form of a first-class Java object, which is an instance of java.lang.Class. Whenever we compile any Java file, the compiler will embed a public, static, final field named class, of the type java.lang.Class, in the emitted byte code.

As programmers we need to log certain information inside our code.But this post from 'Coding Horror' blog describes some things you need to know about logging.

When it comes to logging, the right answer is not "yes, always, and as much as possible." Resist the tendency to log everything. Start small and simple, logging only the most obvious and critical of errors. Add (or ideally, inject) more logging only as demonstrated by specific, verifiable needs.
