From the referencing pages:
Intermediate paper for Delphi programmers starting to use Linux. It explains how to use and integrate Linux and Kylix with Windows and Delphi.�
As a Delphi developer, you will find C# easier to learn than you might have thought. Get a head start with this revealing presentation.�
This session describes COM, CORBA and SOAP, indicating what they share, what sets them apart, and how you can choose among them.�
This session provides a demonstration of ReCruit, including a discussion of its development and deployment process. ReCruit was built using Delphi and InterBase.�

This article focuses on how an application developer can build a successful scalable enterprise application when he or she has only a local database or transaction system available. Availability is not addressed, merely scale and correctness.
I’m re-reading [WayBack] Life Beyond Distributed Transactions – ACM Queue as it such a great article.
Via: [WayBack] Pat Helland on scaling: If you are not willing to pay the cost of distributed transactions, what options do you have and what are the costs associated with this choice – Kristian Köhntopp – Google+
Executive Summary: embrace uncertainty. It can’t be avoided.

Of the things not possible with generics in Delphi, I already wrote about Impossible: Property using Generics in Delphi.
Now it’s time to write about simulating a free function with generics as this is impossible:
function CreateManaged<T>(const value: T): IManaged<T>;
Usually I create a static record method for these, as records do not have VMT overhead, less RTTI overhead and I’ve been used to see records as helpers for other types long before helpers initially were introduced in Delphi 8 to extend classes..
Spring4D has an excellent example of such a record workaround in the Managed.New<T> commit:
type
Managed = record
public
class function New<T>(const value: T): IManaged<T>; static;
end;
...
class function Managed.New<T>(const value: T): IManaged<T>;
begin
Result := TManaged<T>.Create(value);
end;
It basically is a factory for classes implementing the IManaged interface.
In the mean time, Managed has been renamed to Shared but the above code shows my point.

A while ago, I found out that [WayBack] Toon Krijthe made a [Archive.is] Delphi 2009 syntax sample which is a great complement to the DelphiAST parser given that Borland/CodeGear/Embarcadero/Idera never published one in the 22+years that Delphi is alive.

After years of (peer) pressure, Embarcadero finally did some client-side [WayBack] HTTP Protocol Related Improvements in Delphi 10.2.2.
The fixes add some features to THTTPClient that have been available in Indy since version 9 (which however requires 1.0.2 OpenSSL binaries support the required functionality):
We have added a new enumeration,
THTTPSecureProtocolwith the values (SSL2, SSL3, TLS1, TLS11, TLS12).THPPTClientand related classes have now aSecureProtocolsproperty which is a set based on that enumeration.

Interesting repository https://github.com/davidheff/DelphiProjectCompileMode in a response to
[WayBack] I’m trying to use Pre-/Post-Build-Events (Delphi 10.1 Berlin, if that matters). Is there a variable, parameter, option etc to distinguish between a “make” and a “build”… – Achim Kalwa – Google+
This requires an expert as Delphi doesn’t do it out of the box, so I was glad this expert solves that: davidheff/DelphiProjectCompileMode: Delphi IDE add in that sets an environment variable to indicate which compile mode (make, build, etc.) was used to start a compile action
It sets the DelphiProjectCompileMode variable to a value depending on the TOTACompileMode:
cmOTAMake -> Make
cmOTABuild -> Build
cmOTACheck -> Check
cmOTAMakeUnit -> MakeUnit
otherwise -> Unrecognised
