There is a ProtoBuf.Net fact regarding using AsReference which somehow I missed when digging into why [ProtoAfterDeserialization] attribute is not applied for some objects.
The truth is that it is applied for some but not other objects even if I used AsReference attribute in some places. The AsReference attribute should be applied to ALL REFERENCES TO THE OBJECT, both collections and navigational properties, NOT JUST REFERENCES OTHER THAN THE REFERENCE WE CONSIDER MAIN ONE.

The FlowDocument along with most of the elements it contains inherits from DispatcherObject class. This means when constructed, it becomes linked to the thread in which it was constructed and causes several implications.

Delphi 2007 is not new although it is the last non-unicode release of Delphi hence it is used frequently to maintain legacy code base.

And it has bugs. Some of them can be fixed by VCLFixPack and affect only compiled binaries.

Some are related to IDE and neither CnPack nor GExperts IDE extensions can fix them.

TortoiseMerge is a useful 3-way merge tool yet it lacks proper keyboard shortcuts configuration and default shortcuts seem to be designed only for basketball players, with fingers stretched from arrow keys up to function keys.
Update: Current Version of TortoiseMerge included in TortoiseGit has the keyboard shortcuts fixed and easy to use

Recently I needed to upgrade a piece of software to do some things easily done in modern user interface libraries say WPF or FireMonkey (which I don't use personally), but requiring more effort to implement in Delphi VCL.

The task in question was to add a drop down menu with TCheckBox controls to a TStringGrid. This has been done countless times and TCheckedComboBox, TCheckBoxComboBox and others alike can be found on the Internet easily. The problem is none have the features I needed:

Today I have encountered few problems while trying to compile PostgreSQL on Windows. PostgreSQL designed to work in *nix environments and it's native build system works flawlessly on Linux just as expected. Unfortunatelly on Windows this build system is used by minority of applications, partially using Microsoft's own version of make: nmake.

In PostgreSQL only libpq.dll can be compiled using nmake in Visual Studio Command Prompt which sets all necessary environment variables for compiler and linker (INCLUDE, LIBPATH etc, type set in command prompt to verify these paths).
