If, like Delphi XE and higher, your organise your projects to use output directories like ...Bin\Delphi####\$(Platform)\$(Config), and back-port to Delphi 2010, then
The Delphi 2010 compiler puts the files in almost the right directory ...\Bin\Delphi2010\Debug\Spring.Tests.exe
The Delphi 2010 debugger barfs with this message:
---------------------------
Error
---------------------------
Could not find program, '...\Bin\Delphi2010\%Platform%\%Config%\Spring.Tests.exe'.
---------------------------
OK
---------------------------
So you might think that it is enough to hard code this in your base configuration:
Platform=Win32
Well no, the debugger still shows the above error message. Despite the compiler putting it in the correct directory: ...\Bin\Delphi2010\Win32\Debug\Spring.Tests.exe
So there are 3 configurations for the output directory:
Base (for documentation purposes only)
Bin\Delphi2010\$(platform)\$(config)
Debug
Bin\Delphi2010\Win32\Debug
Release
Bin\Delphi2010\Win32\Release
You might think: why is Spring4D still supporting Delphi 2010?
Two simple reasons:
many people still use it
it produces relatively small executables, which still is important in some situations like producing our own Build tool and keeping binary versions of that in our version control system
I’ve a VM with many Delphi versions and want to clean up space from %ProgramData% to install more. I think somewhere in the comments it was mentioned what to delete from %ProgramData% to lessen the disk space used by Delphi installations. […]
The VM is on an SSD, and the GUID directories there total to about 50 gigabytes.So any reminder what I can delete there would be much appreciated (:
Besides saving disk space, another advantage is that you get far less duplicates when indexing your filesystem with Everything: the directories contain copies of all files also present in the final installation (like %ProgramFiles%, etc).
Thanks to Ilya S, below are my notes for cleaning up a machine that has Delphi 2007 and Delphi 2010-XE6 installed.
In these folders, backup delete all subdirectories but the directory OFFLINE. Don’t delete files. Keep the backups in case you need them.
Generic support in Delphi took a very long time to get stabilised. Which means that compilers older than Delphi XE2 are hardly usable for code using generics. XE did get better, but Delphi 2010 and especially Delphi 2009 were hopeless.

Since the table there is incomplete (even the Embarcadero documentation is wrong as some shortcuts can turn on and off a mode), here are the relevant shortcuts keys:
Ctrl + O + C
Turns on/offblockcolumn selection mode
Delphi 5 and up
Ctrl + O + K
Turns on/off block selection mode
Delphi 5 and up
Ctrl + O + L
Selects current line (and turns off block selection mode)
Delphi 5 and up
This is especially useful when the block selection is stuck (this happens every now and then: it’s a known bug).
AOP allows you to perform separate of concerns (SoC) in your application, especially in the area of cross-cutting concerns like for instance logging, authorization, monitoring, etc.
It took a while in Delphi to allow for AOP, but the TVirtualMethodInterceptor (that introduced in Delphi 2010) can be used to do AOP (only for Virtual Methods, which is still way better than having no AOP at all).
The code requires a lot of manual labor. so I was glad that DSharp (a great library by Stefan Glienke – one of the leading Spring4D contributors) contains a nice wrapper around TVirtualMethodInterceptor so you can use AOP in an attribute based fashion.
Nick Hodges recorded a good introductory video on AOP in Delphi with slides and demo code:
