One of the really nice contributions on StackOverflow by Allen Bauer is almost 3 years ago.
It is about these three Delphi VCL methods introduced by TWinControl to make control development easier:
The really cool thing is that this API has been stable since 1995, and still allows you to subclass windows controls or create your own controls in a very simple way.
Note that Allen does not cover DestroyWnd or DestroyWindowHandle, but those are just counterparts of CreateWnd and CreateWindowHandle.
In normal Delphi application code, you have less Destroy overrides than Create overrides, and the same holds for control development.

Just in case you wonder about Property using Generics in Delphi, they are not possible.
Thanks David for mentioning it, Hallvard for mentioning it even earlier and Rudy for confirming it.
These are supported with Generics in Delphi:
All of the supported aspects are linked to articles from excellent authors. There is far more on the internet about Delphi and Generics, but those are a good start.
Thanks Malcolm, Phil, Barry, Hallvard, Jolyon and many others for posting all those articles!
Note that this is not possible in C# either, Julian Bucknall organized a chat and explains why, but there is a workaround which I might try to port to Delphi in the future.

If Gloegg@Bonn has posted a few nice Delphi entries over the last couple of years, so he should be added to DelphiFeeds.
His last one was a very funny post on the Delphi implementation of Sleep sort.
It uses Generics, so you need at least Delphi 2009 or better.

Jim Tierney isn’t on DelphiFeeds yet, so below are a few links to his great Delphi XE3 LiveBindings posts.
Jim is one of the people that developed LiveBindings. In addition to that, he explains things very well.
He did some great posts on LiveBindings after Delphi XE2 got launched (he also did two great presentations on Delphi Live 2011 and CodeRage 6 – they got repeated on the last 24 hours of Delphi).
Now he is publishing a series of posts on LiveBindings in Delphi XE3.
These posts are recommended reading, more are probably on their way:

Cool: learned something new here:
About the path names of files being in the .dproj as well as in the .dpr:
@Jeroen – Looks like msbuild might need those entries, otherwise they’re possibly redundant, AFAICT… In any case, there is not much editing involved, just delete ‘dccreference’ entries and then a ‘save all’ in the IDE regenerates them. – Sertac Akyuz

While scheduling this year’s projects, it was clear that it would become impossible to have the summer holiday in the summer (last year was also outside, as we fulfilled Nicolette’s dream: visit the Antarctic region).
So we moved this year’s holiday to early November, hoping that would be outside the Fall conference season.
Alas, EKON (Entwickler-Konferenz.de), this year in Düsseldorf, Germany, moved themselves to November, so this will be the first EKON ever that I won’t attend (out of 3 or 4 people that never missed one). Sorry guys I will miss the great speakers, sessions and workshops (:
I am going to speak on two other European Delphi conferences though:
I’m really looking forward meeting the attendees, speakers and organizations there. Conferences are always a lot of fun and a great way for me of learning new things.

Two days ago I ran into the bug below while porting some code from Delphi 2006 to Delphi XE2, posted on StackOverflow, and got solutions in very little time.
Thanks Andreas Hausladen, David Heffernan, Ken White, Sertac Akyuz, Rudy Velthuis, for answering, providing solutions and verifying!
Note that this worked up until Delphi XE, and has been fixed in Delphi XE3 (which for this project I can’t use as the client upgraded to XE2 without SA).
Problem
- I get the error mentioned further on error when debugging an executable in Delphi XE2 update 4 under these circumstances:
- that depends on mqic.dll from WebShpere that is in C:\Program Files \IBM\WebSphere MQ\bin\mqic.dll and C:\Program Files\IBM\WebSphere MQ\bin is on the system path (not on the user path).
- is being debugged with an override environment variable in the Run -> Parameters -> Debugger -> Environment Block -> User overrides
- Including System Variables on the same property page is checked
This is the error (it’s a Windows DLL load error marked “System Error”).
The program can’t start because mqic.dll is missing from your computer. Try reinstalling the program to fix this problem.

Today I found out the hard way that you really need a build integration system for managing VersionInfo in Delphi applications: as of Delphi XE2 it is broken in the IDE.
See these links:
This is the only workable workaround so far:
