A man in a hurry is always late.

Ternary is the correct term for computer language operators with three parameters. https://en.m.wikipedia.org/wiki/Ternary_operation

I wrote a small cookbook on getting Ubuntu up and running and setting up Rio and Sydney for compiling Linux applications.

Defintively a valid point. You can install 18.04 in a VB VM as well, and the rest remains the same.

TimeSpan allows you to measure in milliseconds without having to think about the underlying details.

An cleaner alternative to GetTickCount, but perhaps a little more costly is System.TimeSpan and System.Diagnostics.TStopWatch?

You could always leave a comment here instead 🙂

Strange, @Bill Meyer. Appears to work for me.

Why... Who knows why.

Well, the old RichEdit demo was removed. Who knows.

Added a miniscule example using FMX for Linux at the end.

I see that the Rich Edit control has "moved" - not sure if the old wrapper supports 4.1? https://docs.microsoft.com/en-us/windows/win32/controls/about-rich-edit-controls VERSIONS OF RICH EDIT Rich Edit version DLL Window Class 1.0 Riched32.dll RICHEDIT_CLASS 2.0 Riched20.dll RICHEDIT_CLASS 3.0 Riched20.dll RICHEDIT_CLASS 4.1 Msftedit.dll MSFTEDIT_CLASS

Oh, BTW - VS Code and Powershell 7 works beautifully under Ubuntu 18.04 🙂

Originally, this was done to try to figure out why @Angus Robertson had issues with getting his Ubuntu environment working.

I am on PS C:\Windows\System32> Get-ComputerInfo | select WindowsProductName, WindowsVersion, OsHardwareAbstractionLayer WindowsProductName WindowsVersion OsHardwareAbstractionLayer ------------------ -------------- -------------------------- Windows 10 Enterprise 1909 10.0.18362.752

The Ubuntu 18.04 that my Hyper-V Quick Create offers me, has the visual UI - so not a pure server, perhaps?

@Angus Robertson I tried Hyper-V Quick Create, and it worked for me, but you need to add the build essentials manually. Wrote a small post about it too. https://larsfosdal.blog/2020/08/26/get-started-writing-linux-apps-with-delphi-10-3-3-rio/ What fails during your installation?

It is unfortunate that the toolchain doesn't keep up with the platforms it is supposed to support.

sudo apt install gcc cured the linker problems, but appeared in the PAserver and followed in the IDE. /facepalm

What went wrong?

This compiled, but it didnt link. 😕 program LinuxTest; {$APPTYPE CONSOLE} {$R *.res} uses System.SysUtils; begin try { TODO -oUser -cConsole Main : Insert code here } Writeln('Hello World'); except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; end.

I just installed Ubuntu 20.04 LTS on Hyper-V on my Windows 10 machine, Advanced Model, 2 cores, 8Gb, no other configuration changes and opening a terminal, and running "ip addr show" - my second adapter shows as 172.17.202.69 Downloaded PAServer, and ran it with the default port Tested connection from 10.3.3 - success.

FWIW, Hyper-V is really easy to install and configure.

Are there any BRCC32 specialties that doesn't work with the MS RC compiler?

Maintain, how? Once the text is written, it rarely needs to be changed after any initial correction. Sentences for UI texts are definitively not ideal - but this worked out so well that we even use this method for hip computer voice responses in multiple languages for our JsonRPC services. We still haven't introduced a fourth language, but if we do - it will be impossible to miss a translation.
