A few weeks ago, Bill Karwin did a must watch webinar on the prevention SQL Injection titled ”SQL Injection Myths and Fallacies“.
Bill Karwin (twitter, new blog, old blog, Amazon) is famous for much work in the SQL database community, including InterBase/Firebird, mySQL, Oracle and many more.
Anyway, his webinar is awesome. Be sure to get the slides, watch the replay, and read the questions follow up.
Watching it you’ll get a better understanding of defending against SQL injection.
A few very valuable points he made: Read the rest of this entry »

Last week I posted an in depth answer on StackOverflow.com about the memory allocation difference in Delphi and Fortran, or more accurately in two different kinds of languages.
- column major order (not only used in Fortran and other science centric languages, but also in the shading languages GLSL and HLSL that can be used in FireMonkey)
- row major order (used in most other languages, for instance Delphi, C, etc)
A very important aspect is the order of for optimized loops. For column major order, the optimum is inside out (as the inner arrays/records are in consecutive memory locations), but for row major order, it is the exact inverse.
One of the consequences is that in Fortran it is a very fast operation to pass an array of inner fields as parameter to a method.

In the past I wrote a few blog posts on posting sourcecode in WordPress.
Their site contains an even more elaborate list of supported languages.
I had the basic list right in my last post, but was missing all the aliases (which often are easier than the longer proper names).
This is the new table adapted from their list: Read the rest of this entry »

While writing this blog entry, I’m installing my new copy of Delphi XE (formerly called Delphi 2011 by some people).
Delphi XE and RAD Studio XE got RTM today, and are now available for purchase.
Contact my colleague Gwan Tan if you want to order it from Dutch speaking countries, and Thorsten Nannen if you want to order it from German speaking countries. Read the rest of this entry »
