It is such a pity that StackOverflow is not the place any more for questions like these:
c# – What’s the hardest or most misunderstood aspect of LINQ? – Stack Overflow.
These questions and answers historically got me most of the insight from SO.
Alas, no more.

This is more elaborate English version of a short Dutch message I recently sent to explain the differences between VCL and FMX:
Do not regard FMX as a replacement for VCL: they are different kinds of frameworks.
VCL is a wrapper around Windows Controls. In itself, it has not much functionality: it exposes the underlying Windows functionality. The exception are data aware controls that provide basic functionality for writing data aware applications. There is a huge 3rd party market for extending VCL support, for instance providing extra Windows functionality, enriching data aware behaviour (look at all those fancy data aware grids), and many more.
FMX is the FireMonkey X-platform framework. Major functionalities are vector based 2D, 3D drawing and controls, and support for styles and composition.
When introducing FMX in Delphi XE2, Embarcadero also introduced a new way of data binding that is shared with FMX and VCL. FMX extends this a bit to some basic data aware controls.
Gone are most of the platform specific features like drag & drop, full blown Windows Shell ListViews, etc. There are some controls that manifests themselves differently on each supported platform (like Pickers), but most of that is currently left to the 3rd party FMX component market.
So if you want FMX to replace VCL, then be prepared for quite some shopping in the 3rd party market.
CLX tried to be a full blown cross platform VCL replacement, but that didn’t work very well.

A while ago, I needed to automatically create a bunch of shortcuts all in the same directory, and all the batch files in a different directory.
There’s different kinds of doing this:
I needed a one-off, so I came up with some code like this. Read the rest of this entry »

Precision Computing is a site by Lee Holmes having a great blog with PowerShell tips. Of course he does, as he is part of the PowerShell team and he wrote Windows PowerShell Cookbook: The Complete Guide to Scripting Microsoft’s New Command Shell.
The Counting Lines of Source Code in PowerShell entry is on counting C# code lines (and shows some great performance optimization tips).
I knew about the blog, and bumped into the entry because of file – Lines-of-code counting for many C# solutions – Stack Overflow.
Last year I inherited a suite of .NET projects totaling about 4 million LOC. Which I want to drastically reduce to make it more maintainable.

Ah, VBScript. It just wouldn’t be the same without these quirky gotchas.
So either perform Call, assign the function result, or use less parenthesis.
Another thing that drives me crazy with VBScript is that you can only specify ByVal or ByRef, but not specify what type a parameter (string, integer, etc) will be.
VBScript will just barf with “Microsoft VBScript compilation error: Expected ‘)’” at the first As. or colon (:) when you declare Sub or Function parameters like this:
The reason is that the colon is end-of-statement token, which means you can string statements together, an can Dim and assign a variable in one line:
To quote ebgreen:
Oh and Debugging VBScript is indispensable (:

So I won’t forget, as the [WayBack] static in different languages varies in meaning:
[WayBack] Static on class methods makes them assignment compatible with plain old function pointers.
Thanks Moritz Beutel for initially posting this.

related:
Like class methods, class static methods can be accessed without an object reference. Unlike ordinary class methods, class static methods have no Self parameter at all. They also cannot access any instance members. (They still have access to class fields, class properties, and class methods.) Also unlike class methods, class static methods cannot be declared virtual.
Methods are made class static by appending the word static to their declaration.

You might think the below question on CodePage zero is Delphi related, but most of it is not.
It is about CP_ACP (the currently Active CodePage, and has some interesting observations:
CP_ACP is the major reason people have difficulties exchanging the data in text files between applications on different computers.
Oh and you can get the actual value of the active Active CodePage using GetACP, but CP_ACP isn’t always slower..
