Fail Fast!

Joy of Programming: Fail Fast!

When a problem occurs in the software, it should fail immediately, in an easily noticeable way. This “fail fast” behaviour is desirable, and we’ll discuss this important concept in this column. At first,…

Compilar optimisation

CodeSport (December 2011)

In this month’s column, we will continue our discussion of compiler optimisations, and focus on compiler analyses and optimisations that require inter-procedural analysis and inter-procedural code transformation. In last month’s column, we had…

Time to Plone

Loop optimisation

CodeSport (November 2011)

In this month’s column, we will continue our discussion on some of the common loop optimisations performed by the compiler. In last month’s column, I had presented a coding snippet (shown below) and…


Joy of Programming: Scope, Lifetime and Visibility in C

Often, programmers confuse the scope, lifetime and visibility of variables. So I’ll cover these three important concepts in this month’s column. Whenever you declare a variable, you determine its scope, lifetime and visibility….

It should be all logical, no?

Exploring Software: GNOME and the Semantic Desktop

Currently, this is a work in progress. So will it mature fast enough and meet user expectations? The state of the semantic desktop in the GNOME desktop environment is still very fluid. Two…

Let's optimise a bit...

CodeSport (October 2011)

In this month’s column, let us focus our attention on some of the common compiler optimisations, and on how to write code that can be well optimised by the compiler. In last month’s…
