The Day Web 2.0 Died

Milinda — Wed, 17 Dec 2008 16:28:55 +0000

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.

Understanding Java Class Loading

Milinda — Tue, 09 Dec 2008 17:44:26 +0000

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.

The Problem With Logging

Milinda — Fri, 05 Dec 2008 14:51:58 +0000

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.

GCC Compiler Extensions Used in Linux Kernel

Milinda — Fri, 21 Nov 2008 18:49:47 +0000

GCC and Linux are a great pair. Although they are independent pieces of software, Linux is totally dependent on GCC to enable it on new architectures. Linux further exploits features in GCC, called extensions, for greater functionality and optimization.

Deadly Linux Commands

If you are new to Linux, chances are you will meet a stupid person perhaps in a forum or chat room that can trick you into using commands that will harm your files or even your entire operating system.
