DelphiTools, SamplingProfiler and General Delphi News
An utility that was added to the DWScript sample WebServer during the 4 TeraPixel Mandelbrot experiment is the BackgroundWorkers API.
This is a rather low-level threading facility that can work well with Global Queues to handle background tasks or serializing tasks.
Once upon a time, there was a war (in the developer meaning), between Pascal, and another language whose name begin with the V and B initials.
Well that war is over.
Pascal won, sometimes in 2010.
A recent addition to dwsDataBase is the DataBasePool static class.
As the names indicates, it facilitates pooling database connections from the script-side, while previously you had to rely on Delphi or driver-side pooling (or lack of).
Happy new Year to all!
The fractals.dwscript.net is now launched to host the results of the recent Mandelbrot TeraPixel experiment. It’s a small website to centralizes browser, documentations, links and downloads.
There was also news of a FireMonkey client for the data set API.
The Christmas Mandelbrot Experiment is now nearing has achieved completion of Level 13, or a Four Terapixel image!
This will be the end of the experiment (at least temporarily) as the server is running out of storage space 🙂
As a step up from the previous Mandelbrot Set explorer, I’m running a Terapixel image experience for DWScript Christmas 2013.
This is again on the Mandelbrot set, and involves a massive step up in complexity from the previous version, this one isn’t just server-side computed, it’s “Grid Computed” 🙂 (more…)
My small utility that gives binary size statistics from the Map file just got updated to version 1.5
This updates improves statistics gathered and reported for DCU file sizes, and introduces a small speedup.
The twist is that the computations are handled server-side, using DWScript JIT compiler, so exploration can be fairly fast and comfortable even on low-powered hardware, be it an iPad, a Smartphone or an old laptop.
Here is a small utility I made whose purpose is to flush (empty) the Windows file cache. It can also flush and purge memory working sets, standby and modified lists.
It can be useful to reduce memory usage of a particular VM (on a host with dynamic memory) or for testing and bench-marking purposes.
