Software industry has tools and processes to help transparency in law and policymaking

Software that we now use constantly in our daily life wouldn't be possible if people creating these systems did not follow the practice of recording even the smallest change to the software in version control systems. Now, political activists all around the world convert legal texts to version control systems in an attempt to open up the lawmaking processes.

Occasional XSLT for Experienced Software Developers

FIrst published in 2004 in DevX

Although using XSLT to process XML is increasingly common, most developers still use it only occasionally—and often treat it as just another procedural language. But that's not the best way to use XSLT. Learn how to simplify and improve your XSLT processing using event-driven and declarative techniques.

XML appears in some form in most modern applications—and often needs to be transformed from one form into another: merged, split, massaged, or simply reformatted into HTML. In most cases, it's far more robust and efficient to use XSLT to perform such transformations than to use common programming languages such as Java, VB.NET, or C#. But because XSLT is an add-on rather than a core language, most developers use XSLT only occasionally, and have neither time nor resources to dive into the peculiarities of XSLT development or to explore the paradigms of functional and flow-driven programming that efficient use of XSLT requires.

Such occasional use carries the danger of abusing programming techniques suitable for mainstream languages such as Java, C and Python, but that can lead to disastrous results when applied to XSLT.

However, you can avoid the problems of occasional use by studying a few applications of different well-known programming problems to an XSLT programming task through this set of simple, thoroughly explained exercises.

"Свинья везде грязь найдёт"

Сегодня я зашёл в блог известного в узких кругах автора Struts Framework и Java Server Faces Крэйга Мак-Кланагана.

Своим некачественным кодом этот человек портил жизнь сотням тысячам программистов, а если учесть, что он ещё и автор Catalina, то миллионам.

Недавно он заинтересовался Ruby on Rails. Берегитесь, рубероиды!

Programmers learning from philosophers

In a paper entitled "Classes vs. Prototypes: Some Philosophical and Historical Observations" and published in 1996, Antero Taivalsaari draws parallels between the evolution of the philisophy and of the Object-Oriented paradigm in programming.

Indeed, the classification of the world was in the center of interests of philosophers since Plato and Aristote. Taivalsaari argues that the traditional class-based OOP builds upon the principles that have first been described by Plato, while there are more sophisticated approaches to categorization, e.g. the so-called prototype theory, started by Wittgenstein, that lays in the foundations of the prototype-based OOP, like what we find the the modern implementations of the JavaScript language.
