Up until Widows 8.1, you could use wuapp to start the Windows Update panel.
For a while, Windows 10 needed a cumbersome language specific workaround described at Windows 10 – language neutral batch file to start Windows.
That stopped working after a few builds, but I forgot to make a note in which build exactly. Already in Windows 10 build 10122, the icon in wucltux.dll, so this might have been shortly after the initial “RTM” (retroactively named 1507).
So for a while, I had this batch file:
Since then I had to maintain too many locales running Windows 10. So here is the batch file:
for /f "delims=" %%A in ('PowerShell -Command "(Get-Culture).Name"') do explorer "%LocalAppData%\Packages\windows.immersivecontrolpanel_cw5n1h2txyewy\LocalState\Indexed\Settings\%%A\AAA_SystemSettings_MusUpdate_UpdateActionButton.settingcontent-ms"It uses these tricks:
- Set output of a command as a variable (in this case a for loop variable)
- Execute PowerShell script in a .bat file
- PowerShell Get-Culture (which gets a .NET CultureInfo instance)
- CultureInfo.Name property (which has the nl-NL, en-US, etc codes in it)
But now I have extended it to support old and new Windows versions:
if exist %windir%\System32\wuapp.exe ( %windir%\System32\rundll32.exe url.dll,FileProtocolHandler wuapp.exe ) else ( %windir%\explorer ms-settings:windowsupdate )

Today, Niklaus Wirth, “father” of The Pascal Programming Language turned 85.
Happy birthday!
Almost 50 years ago, Niklaus Wirth submitted his famous paper “The Programming Language Pascal” which was published early 1971
Luckily it is archived on both the WayBack machine and Archive.is as the only PDF copy I could find on-line isn’t always on-line: http://oberoncore.ru/_media/library/wirth_the_programming_language_pascal.pdf
Originally it was published by Niklaus Wirth in Acta Informatica, Vol. 1, Fasc. 1, 1971 pp. 35-63
He has been very active, just browse through the [WayBack] List of computer science publications by Niklaus Wirth
To celebrate his birthday, here are some interviews with him:
If you like the ones above as much as I do, then search for more: there are plenty!

Interesting read [WayBack] Mysterious Case Of Wrong Value.
In order to capture by value (which in C++ you can specify), you need an intermediate function like Dalija describes:
function CreateFunction(Value: Integer): TFunc<Integer>;
begin
Result :=
function: Integer
begin
Result := Value;
end;
end;

Somehow I’ve been doing Unix like work off and on for most of my life. So I know many ancient shell shortcuts (like Ctrl-E for end-of-line and Ctrl-A for start-of-line) by heart.
Many don’t, or even list shortcuts as if they are for the shell, but in fact aren’t.
So here are some links that distinguish between various kinds of keyboard shortcuts and give some insight in the history of these shortcuts (that go back into the 1970s, yes I’m that old).

Of course you don’t want this. So by the time you read this, the connection has been closed.
For testing some Internet of Shit stuff from a client that cannot do SFTP, I needed a temporary FTP accessible connection.

The Ribbon controls got removed since Delphi 10.1 Berlin, but the dependency in Vcl.ScreenTips remained, so:
After installing the official Delphi Berlin Update 2 I have faced nasty problem. One of my unit was using the Vcl.ScreenTips unit (for TScreenTipsWindow). And when you compile such a project you ge…

In the mean time however, it has been moved to GetIt: [WayBack] Ribbon Controls in RAD Studio 10.1 Berlin.
Note that the XE8 introduced [Archive.is] GetIt package manager is under the Tools menu, which is not covered by [Archive.is] IDE Insight – RAD Studio.
Anyway: here you can get it in Delphi 10.1 Berlin (now also in 10.2 Tokyo, where at first it was not available through GetIt):

Wow, impressive work, and a very good explanation of some of the optimizations that take place and how you can check which ones work on your code: [WayBack] Why the New V8 is so Damn Fast – NodeSource:
The entire V8 compiler pipeline was overhauled and shipped with Node.js version 8. This post investigates what speed improvements we can expect as a result.
