Brilliant solution by Asbjørn Heid:
So the solution I came up with is to use the observation that the “array of const” is “array of TVarRec”, and that “array of TVarRec” is passed as as two arguments: a pointer to the data and the length of the array (or rather, the highest index in the array).

I’ve been using cURL but always had a feeling not to its potential basically because the cURL man page [WayBack] is both massive and lacks concrete useful practical examples.
For instance, I knew about the --header and --verbose options (I always use verbose names even though shorter -H and -v exist) to pass a specific header and get verbose output, but the man page basic examples like this by Tader:
curl --header --verbose "X-MyHeader: 123" www.google.comsource: How to send a header using a HTTP request through a curl call? – Stack Overflow [WayBack]
There are some more examples at bropages.org/curl but they’re hardly organised or documented.
So I was really glad I found the below answer [WayBack] by Amith Koujalgi to web services – HTTP POST and GET using cURL in Linux – Stack Overflow.
But first note that recent versions (around 7.22 or higher) of cURL now need to combine the --silent and --show-error (or in short -sS) parameters to suppress progress but show errors: linux – How do I get cURL to not show the progress bar? – Stack Overflow [WayBack]

It’s from a while ago, so I wonder if this is still true:

Besides the optimised versions of these functions, I learned the most from these comments:
Updated code, added lookup-table optimizations, Lazarus / FPC support and test project:
+Javier Hernández In the past I used AQTime but now I’m using NexusDB Quality suite (http://www.nexusdb.com/support/index.php?q=qualitysuite) and +Eric Grange SamplingProfiler (https://www.delphitools.info/samplingprofiler/).
But in this FastDateTime code the test project uses TStopWatch (GetTickCount in FPC) to compare speed

Marco Cantu (right) and Jeroen Pluimers (left) in 1997
The BorCon 97 opening – today 20 years ago – was so much fun: the a Star Wars like opening crawl about a tiny company fighting the – then regarded – Evil Empire called Microsoft.
It was back in the days when lots of new things in the Delphi world were happening: Delphi 2 – the first 32-bit version – came out half a year before and the upcoming Delphi 3 was going to be a game changer as well. New features were rock solid and sales were booming.
Personally, I was much slimmer (yes, that’s me in the Tie-Dye), and could do a pre-conference tutorial on CORBA and VisiBroker (The ORB by Visigenic which was about to be acquired by Borland – which now is owned by Micro Focus only after spinning of the CodeGear which got acquired by Embarcadero that is now owned by Idera which feels like the Inprise story all over again).
I got triggered to this after watching the Opening Night Excitation episode 194 of the Big Bang Theory:

A while ago, I had to fix some stuff in an application that would write – using a binary mechanism – UTF-8 and UTF-16 strings (part of it XML in various flavours) to the same byte stream without converting between the two encodings.
Some links that helped me investigate what was wrong, choose what encoding to use for storage and fix it:
TEncoding.UTF8.GetBytes: utf 8 – String to byte array in UTF-8? – Stack OverflowSysUtils.ByteLength() is not the nicest function, so use only for a quick-fix Delphi Unicode String Length in Bytes – Stack OverflowAnsiString, UnicodeString et al: String Types (Delphi) – RAD Studio–jeroen

It looks like Microsoft and Embarcadero solved their ends for [WayBack] Windows 10 Creators update and Delphi debugging don’t go well… :
The issue was caused by the Windows LoadLibrary trying to optimise loading which backfired for libraries (PE files like DLL/EXE…) that have multiple import tables in them as generated by the Delphi and C++ Builder linker (and maybe other linkers as well).
Microsoft finetuned their optimisation whereas a future update to Delphi and C++ Builder will generate more optimised import tables.
