From a StackOverflow question about a freezing Delphi application, I posted some experiment-based debugging tricks.
May help any developer in his/her fight against random bugs...

Which Delphi compiler produces faster code?
By A.Bouchez on 2011, Thursday June 16, 21:55 - Pascal Programing
After a question on StackOverflow, I wanted to comment about the speed of generated code by diverse Delphi compiler versions.
Since performance matters when we write general purpose libraries like ours, we have some feedback to propose:
- The 4,500,000 unitary tests of our SQlite3 ORM Framework;
- The SynLZ compression algorithm.

Enhanced logging in SynCommons
By A.Bouchez on 2011, Thursday April 14, 05:34 - Open Source libraries
Logging is everything... unless you never wrote a bug in your program!
Let us introduce a new logging class:
- logging with a set of levels;
- fast, low execution overhead;
- can load .map file symbols to be used in logging;
- compression of .map into binary .mab (900 KB -> 70 KB);
- inclusion of the .map/.mab into the .exe;
- reading of an external .map to add unit names and line numbers to a log file without .map available information at execution;
- exception logging (Delphi or low-level exceptions) with unit names and line numbers;
- optional stack trace with units and line numbers;
- methods or procedure recursive tracing, with Enter and auto-Leave;
- high resolution time stamps, for customer-side profiling of the application execution;
- set / enumerates / TList / TPersistent / TObjectList / TContainer / dynamic array JSON serialization;
- per-thread or global logging;
- multiple log files on the same process;
- integrated log archival (in zip or any other format);
- Open Source, works from Delphi 6 up to XE.

Unit Testing light in Delphi
By A.Bouchez on 2010, Friday July 23, 15:35 - Pascal Programing
Automated Unit Testing is a great improvement in coding safe applications.
If you don't know about it, visit http://xprogramming.com/index.php then come back here, and you'll discover how we implement unit testing in a KISS way, in pure Delphi code.
