A first v0.1 preview of cefHtmlSnapshot is now available at https://github.com/EricGrange/cefHtmlSnapshot.
This is a command-line utility that aims to take image (PNG, JPG) or PDF snapshots of an HTML website or file, and fill in the “void” left by the abandon of Qt webkit tools like phantomjs or wkhtml2pdf. While those old utilities still work, they do not support modern web standards, and any tidbit of ECMA6 will have them stumble.

Units to support the TurboJPEG library is now available in the DWScript repository, you can find the relevant files in the Libraries\GraphicsLib folder, they have been tested with Delphi 10.3 in both Win32 and Win64. The DLLs are those of the latest 2.05 version.
The TurboJPEG library (aka “libjpeg-turbo”) provides a fast implementation of the libjpeg API, but the files here target the TurboJPEG core, rather than the libjpeg compatibility layer (see its documention).
The TurboJPEG API is less rich, but quite simple to use and very convenient.
Committed to daNeuralNet a first working version of a JIT for matrix-vector multiplication that relies on the FMA instruction set (Fused Multiply and Addition).
This version generates code that is up to twice faster than the OpenBLAS for matrix sizes up to CPU cache size (100×100 to 200×200 usually), and maintains a marginal lead for larger sizes, though those are bound by memory bandwidth. The performance profile is similar on both AMD and Intel CPUs.
A test version of SamplingProfiler 64bit is available here (3.2 MB).
It has only been tested with 64bit binaries compiled by Delphi 10.3 and detailed map files. It should work with other Delphi version, (TD32 and other debug information formats have not been tested yet).
There other known issues with stack traces from DLLs, so it is rough around the edges but should be functional.
Just created a new repository with a “LibCBLAS” unit meant to use the OpenBLAS library in its Windows 64bit incarnation from Delphi 10.3+
https://bitbucket.org/egrange/libcblas/
OpenBLAS is an optimized BLAS library (Basic Linear Algebra Subprograms), the DLL itself can be obtained from the “xianyi” repository where pre-compiled Windows DLL are maintained.
