SamplingProfiler v23.3.14 is now available.
This is a bugfix release with stability and performance fixes for the recently added dynamic code support, as well as fixes to automatic source code paths (thanks
Stefan Glienke for reporting testing)
A new Sampling Profiler version 23.3.6 is available, this version adds support for dynamic code, such as for Just-In-Time compilation.
This allows declaring dynamic code blocks to the profiler, so they can be reported as something more meaningful than a bunch of question marks ‘???’.
In practice, there are two new commands you can pass with OutputDebugString. (more…)
After years of beta, the 23.1.23 version of SamplingProfiler is available from its downloads & changelog page.
The download ZIP includes both 32 & 64bit executables.
The main change since the last version is that the code to detect Delphi browse paths was rewritten to accommodate future (unreleased) Delphi versions… as long as the registry names and keys follow the current logic. The previous version supported all Delphi versions, but you had to manually specify browse paths.
I recently dusted off an artificial neural network project, now published at https://bitbucket.org/egrange/daneuralnet/. This is a subject I’ve been dabbling on and off since the days of 8 bit CPUs.
The goals of the project are twofold: first experiment with neural networks that would be practical to run and train on current CPUs, and second experiment with JIT compilation of neural networks maths with Delphi.
TensorFlow and Python are cool, but they feel a bit too much like Minecraft, another sandbox of ready-made blocks 😉
A new version 1.8.1 is available from the SamplingProfiler page.
This minor updates fixes the displayed source code for samples gathered on a generic method (“Show Source Location” option) and other minor fixes.
Work and processing classes are typically short-lived, created to perform one form of processing or another then freed. They can be simple collections, handle I/O of one kind of another, perform computations, pattern matching, etc.
When they’re used for simple workloads, their short-lived temporary nature can sometimes become a performance problem.

Version 1.8.0 of SamplingProfiler is now available.
The options dialog now support Delphi XE2 & Delphi XE3 search/browse paths, other changes are only indirect fixes/improvements related to the components and libraries used in SamplingProfiler.
Just committed to the SynEdit SVN a few enhancements:
edit 27/12: committed another optimization, AFAICT, when working on large files, SynEdit is now faster than the Delphi IDE code editor and *way* faster than Scintilla/notepad++ 5.9.6.2 (with and without a syntax highlighter like DWS’s)
Version 1.7.7 of Sampling Profiler has been released, you can grab it here (642 kB), this version fixes the following issues:
You can now download SamplingProfiler 1.7.6 (642 kB), version highlights are:
Thanks goes to Dan Bartlett for the suggestion that led to the Win7 compatibility fix!
