THE HEXDUMP MAN page, I find, is not the best written example of an applications manual. I recently had a task of finding the addresses of filename encounters generated when a bunch of files were written to an uncompressed jffs2 partition. Normally I’ve been sticking to the simple hexdump -C Read more…
THE C++ INHERITANCE model can be unintuitive some times – or perhaps more correctly, its easy to get tricked by C++ in some circumstances. When having an existing code base the need sometimes comes up, that an often used class is needed with a few additional features. Not to mess Read more…
REGULAR EXPRESSIONS ARE a powerful friend, but the friendship doesn’t come easy. Regular expressions can be somewhat baffling getting a grasp on, but when finally understood, the possibilities are almost endless. When developing the searching expression used in HTML Parsing With Beautiful Soup I realized that my regular expression knowledge Read more…
BEAUTIFUL SOUP IS an HTML/XML parser written in Python. Beautiful Soup excels as an easy to use parser that requires no knowledge of actual parsing theory and techniques. And thanks to the excellent documentation with many code examples, it is easy to fabricate some working code very quickly. On Debian, Read more…
WHEN BEGINNING C++ programming I’ve experienced people to have trouble remembering the correct construction and destruction call order. Personally I conquered this using a common memory technique – creating a story. Here are two stories that might help in remembering. The stories might seem quite long, but don’t fear, it’s Read more…
AFTER SOME TIME of using tarballing as a source revision control system, I thought it was about time getting back to using a real tool for managing my source code. I’ve then used Perforce as my VCS for some time now. At work we are using ClearCase and from what Read more…
SOURCE CODE COLORING in WordPress is thankfully a pretty simple task, thanks to the WordPress plugin system. This allows for installing filters to do the coloring and formatting automatic. Several plugins exists for WordPress to do source code coloring, but (for now?) I’ve settled on the Wp-Syntax plugin. Not that Read more…
AT MY DAILY work we use MIB’s extensively for product configurations. This often brings up the need to recreate a certain configuration sequence. If the scequence is not included in the normal test suite, and the sequence is more that just a couple of OID’s, I usually create a small Read more…
REPLACEMENT NEW CAME to mind, when working on a C++ project of mine. In this project some large objects of short lifetime led to a concerns about memory fragmentation on the targeted embedded platform that have only sparse memory ressources. The life cycle of the objects was to create an Read more…
