There was an interesting thread a while ago: [WayBack] What’s the point of having abstract classes in Delphi? – Agustin Ortu – Google+
The answer is none (the documentation warns you against it – see Constructing instance of abstract class – the compiler doesn’t), so Stefan Glienke submitted this bug: RSP-10235: No warning for .Create on class declared as TClass = class abstract
This post is a reminder to myself to see if any progress has been made by the compiler engineers.

With fresh libraries – like new Delphi and Windows versions – I usually take a pause to see if any major updates have been published to stabalise things.
So about half a year after the release of A new mutlti-threading library for Delphi. (darkThreading) – Chapman World [WayBack], this is a reminder for me to try it.
With the Task Parallel Library still not being up to par, I wonder how DarkThreading compares to the very stable [WayBack] GitHub – gabr42/OmniThreadLibrary: A simple and powerful multithreading library for Delphi.
The source is at [WayBack] GitHub – chapmanworld/darkThreading: Platform agnostic light-locking threading library for Delphi (part of the DarkGlass project).
Note that by now it has moved to [WayBack] DarkGlass/darkLibs/darkThreading at master · chapmanworld/DarkGlass · GitHub (thanks Stefan Glienke for figuring that out)
One comment already: the [WayBack] darkThreading/Building.md at master · chapmanworld/darkThreading · GitHub describes dependencies on the below libraries, but does not use git modules (see [WayBack] Git – git-submodule Documentation) to reference to known stable commits of them:
In the man time, Edwin Yip has reviewed it: [WayBack] Simple Comparison of OmniThreadLibrary and darkThreading (http://chapmanworld.com/2018/05/24/a-new-mutlti-threading-library-for-delphi-darkthreading/) … – Edwin Yip – Google+ after in may he indicated he would look into it at a later stage [WayBack] http://chapmanworld.com/2018/05/24/a-new-mutlti-threading-library-for-delphi-…

An interesting question [WayBack] Just curious,Is there ever a benefit to not providing a GUID in an interface? – Johan Bontes – Google+
The answer is simple: The benefits are almost none and you loose compiler assisted casting ease.
The interesting bits are the discussion where even Embarcadero isn’t sure what kind of magic the compiler does on generic interfaces.

I have seen things like this happen in way to many places, not just C/C++:
static_assert( -1 < 1U );//fails!
Take away:
Never ever use explicit casts merely to get rid of warnings (whether signed/unsigned or otherwise)

Interesting stuff:
In this article we will expand on our TgoHttpClient class by adding some core new features including non-blocking http responses, unifying HTTP 1.1, HTTP/S and HTTP/2 support into a common class…

I’d also be interested in the server part of this, but it seems not there yet.

Delphi 10.1 Berlin broke [RSP-19557] TParallel,Join does not create enough threads – Embarcadero Technologies. It was reported 9 months ago, and since it took quite some longer than a year for a new Delphi version to be released, I wonder if it is fixed by now.
