DWScript happenings and new logo
Long time, no post here, but not no happenings on the DWScript front 🙂
Behold a “cleaned up old logo” for DWScript, which will replace the old one until a better one is made
Delphi XE6 32bits and Scimark
In a Google+ comment to my recent article about inlining in XE6, Leif Uneus posted results from Scimark.
It appears that XE6 is about 30% slower than previous versions at least from XE5 to XE for 32bits floating point.
Note that Scimark does not make use of inlining, but does make heavy use of floating-point computations, loops and arrays.
Edit: issue discussed here was reported in QC 124652 (now marked as resolved)

A Look at Improved Inlining in Delphi XE6
First noticed by dewresearch, Delphi XE6 introduced a new optimization for inlined functions that return a floating-point value.
Here is an exploration of what was improved… and what was not improved.

New DWS WebServer release
A new pre-compiled release v2014.04.04 for the DWS WebServer is available from the downloads page, it is compiled from the latest source.
Besides the usual demo sites, it has been used to serve a crypto-currency block-chain explorer website that peaked at 1600 page views / hour after some successful tweets went viral.
Using reCAPTCHA in DWS WebServer
We’ve all encoutered reCAPTCHA, as it’s one of the few effective ways to protect form submissions from bots on the internet.
Acquired by google in 2009, it comes with multiple plugins for various web environment, here is a plugin for DWScript.
Cryptographic Library for DWScript
There is now an embryo of standard cryptography support for DWScript through the dwsCryptoLib module. The implementations are currently based on DWScript binaries and downloads
As Google Code no longer allows downloads, I will incrementally relocate the DWScript downloads on this website.
The first of the new downloads is an updated binary installer for the DWS Web Server.
BackgroundWorkers in DWScript
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.
Pascal vs Archetypal Enemy
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.
DataBasePool in DWScript
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).
