From a while back: [WayBack] Open Apple #66 (December 2016) : Glenda “The Atom” Adams | Open Apple
This month on Open Apple, we sit down with Glenda Adams, better known on the Apple II as The Atom. She was a cracker of some note back in the 1980s, and she shares great stories with us…
It reminded me of the days I started to learn programming. Good memories. @glenda_atom was way ahead of me (:

Interesting thread at [WayBack] Max Schrems on Twitter: “WTF?! So the “solution” of #Facebook, #Goolge or #Microsoft for #GDPR is to claim they have a “legitimate interest” to take all the data they can get their hands on and use it for any of their “products” (incl. ads)… 😧😭 #BeggingForThe4Percent”.

Interesting as bgInfo does not support top most windows or overlay: it only does the Desktop background, and you need to go through hoops to recreate the background on each logon:
Enter dzComputerInfo. It’s a small tool that I wrote the evening after the above incident which does exactly one thing: It shows a window on top of all other windows displaying the computer name and currently logged on user. Since the window is so small and it places itself automatically just above the start button, it does not really become a nuisance.
The tool and the source code is available from sourceforge, if anybody else thinks he has a use for it.
The G+ thread also the interesting comment by Gaurav Kale:
The Classic Shell Start button supports environment variables in its tooltip. So just specify: %username% on %computername% for the Setting called “Button Tooltip”. Then to see the currently logged on user and computer name, you just have to HOVER over the Start button!

A poster showing how to prepare your Oracle database for GDPR. Wait for the email download link by visiting GDPR for database professionals and DBAs. Poster (they mention to be GDPR compliant in [WayBack] their policy), or look at the WayBack machine to download it now.
One takeaway for me: you also need to scrub backups when removing someone your records.

Generics and constraints in Delphi is still a bit of pain.
A while ago, I needed a factory for threads. It was more convoluted than I meant it to be, so I had a short chat with Stefan Glienke.
He came up with an example similar to the one below. I tore it apart so you can on each line see what the compiler dislikes.
This fails, but was kind of how I wanted it to be:
type
TFactory = record
class function Manufacture<T: TBaseClass, constructor>(parameter definitions): T;
end;
class function Manufacture<T: TBaseClass, constructor>(parameter definitions): T;
begin
Result := T.Create(parameter values);
end;Which means I need to update Delphi Constraints in Generics – RAD Studio XE documentation wiki
The factory:
type TComponentFactory = class class function CreateComponent<T: TComponent>(AOwner: TComponent): T; static; end; class function TComponentFactory.CreateComponent<T>(AOwner: TComponent): T; var ComponentClass: TComponentClass; Component: TComponent; begin ComponentClass := T; Component := ComponentClass.Create(AOwner); // you can't do `T.Create(AOwner)` Result := T(Component); // you can't do `Result := ComponentClass.Create(AOwner);` end;
The usage:
var Component: TButton; Owner: TComponent; begin Owner := Application.MainForm; Component := TComponentFactory<TButton>.CreateComponent(Owner); Component.Parent := Owner; end;
Full source example is at: After a discussion with Stefan Glienke: a pattern for a factory, this one for components, but can be uses for anything having a base class like a TThread descendant.
In the mean time, Spring4D has added the [Archive.is] Spring4D: TActivator record with many CreateInstance methods that allow you to create instances of classes for which you just have type information.

class function Manufacture<T: TBaseClass, constructor>(parameter definitions): T;

| Result := T(Component); // you can't do `Result := ComponentClass.Create(AOwner);` | |
| end; |
| var | |
| Component: TButton; | |
| Owner: TComponent; | |

| Owner := Application.MainForm; | |
| Component := TComponentFactory<TButton>.CreateComponent(Owner); | |
| Component.Parent := Owner; | |
