So if I am the Primary Contact (as I paid the bill myself) I still have to assign myself somewhere as an Authorized Contact? Damn, the Embarcadero's sales model does not change with years, they are targeting businesses, not developers. And don't remind me about all this reseller-only distribution and obligatory quote request for updates ☠️...

Same here.

I guess yes (the {$INTERFACES} directive is local) but honestly I have not tried it myself because it is incompatible with Delphi code

You mean something like CORBA interfaces as implemented as FreePascal? They are exactly this: a set of methods, not refcounted.

Pred() and Succ() are simple iterators defined for enumerable simple data types. If only they could be overloaded for other data types (lists, collections, whatever... maybe even for yield support) their usefulness would be much higher.

There is nothing difficult. You can use a serial port (if the host PC doesn't have one, a simple USB-to-COM adapter will do) as a simple communication channel - serial data exchange has been used for decades in multiple industrial applications built with Delphi. In fact, this is the area (custom hardware control / monitoring) where Delphi is used in many companies, but of course most of these applications never appear in public.

There is well known RemObjects SDK which I think still supports even Delphi 7. Some interesting information regarding JSON support is here: https://talk.remobjects.com/t/how-to-call-rest-server-with-json/18771 . A standard SOAP support has been a part of Delphi RTL since forever and usually works without problems.

I have been using HxD since.. well... 2009 or 2010, I think. This is an excellent tool!

ExpressQuantumGrid by default (in the Bound mode) fetches all data from the database table and then uses it for the fast local filtering / sorting / etc functions without further database operations (unless an update is required). There is another mode (Server mode) where data is fetched as needed but in this mode local grid filtering is limited.

You haven't tried to use the Linux debugger yet, have you? The 64-bit debugger in 10.1 is a piece of cake compared to 10.3 Linux one...

The problem is that OTL is unfortunately Windows only, where it wins hands down. On the other hand, PPL with all its quirks is cross-platform. When porting to Linux, I had to write two versions of the same code, ifdef'd to use OTL on Windows and PPL on Linux. Not an elegant solution but I did not want to touch the working Windows code...

I always remember the Peter Gottschling's description of a program comment from his book "Discovering modern C++":

Ok, I knew somebody must have implemented it already: https://blog.grijjy.com/2017/04/20/cross-platform-timer-queues-for-windows-and-linux/

Look at CreateTimerQueue / CreateTimerQueueTimer. Nothing too difficult but needs a callback and probably an event and thread to wait on it.

Because this font family (JetBrains Mono) does not have some internal flag marking it as "monospace". Visual Studio / Windows terminal also do not recognise it as such. Let's wait for a service pack 😉 There is a discussion on this topic in Russian (https://habr.com/ru/company/jugru/news/t/484134/). In fact, I did not like the look of this font when I tried it in Notepad++, YMMV.
