Kontact is my default PIM application. On its configuration we can setup a phone calling program, such as ekiga, skype and others, it just requires a small script, like the one bellow, which I have integrated with KPilot, so I can manage my contacts centered and synchronized.

ramblings on email formalization

by Daniel Molina Wegener on 07.02.2010

Netiquette (RFC1855) is a set of standard rules on writing electronic mail. Many of those conventions appears to be lost in time, and bad practices on writing emails are more popular around the Internet. I agree with those rules, but I think that some additional stuff can be used to get more organized electronic mail. Here are some rules, some of them extracted from the netiquette used on mailing lists and Usenet.

development commandments

by Daniel Molina Wegener on 08.01.2010

I don’t use recipes to ensure the quality of my software. Most of those development tasks to make the software a reliable tool are techniques learned along the time, without considering the methodology behind the software development. I can’t stand for any methodology as the better methodology that you can use. I just follow few commandments or rules on software development, and all of them bring me good results.

source code optimization in c

by Daniel Molina Wegener on 31.12.2009

"…premature optimization is the root of all evil".
— Donald Knuth

I agree with the fact that we must do our source code level optimizations when we have finshed the construction stage or it is almost complete. I was searching articles and papers about optimizing C source code to be applied on my programs and libraries. I’ve collected some of those optimizations. But you must not confuse algorithm optimization, source code optimization and compiler optimization, since the first one refers to algorithm design and the second one just refers to the algorithm implementation, and both are sharing just few common approaches to formal reductions.
