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.

Not really. Usually I just create a keyboard macro on the fly to make the template, and then I fill in the texts afterwards.

Normally we use Sisulizer, but it is hard to keep track of context in Sisulizer, so for enums we have this "dirty" workaround which also prevents missing translations.

It probably is no consolation that I also have hundreds of these helpers... TAllowState = (asAllow,asWarn,asDeny); TAllowStateHelper = record helper for TAllowState const Translate: array[TAllowState] of xlt = ( { asAllow } (no:'Tillatt'; se:'Tillåten'; en:'Allow'), { asWarn } (no:'Vis advarsel'; se:'Visa varning'; en:'Show warning'), { asDeny } (no:'Sperret'; se:'Sperrad'; en:'Denied') ); public function ToString(const Language: TLanguage = langDefault): String; inline; class function FromString(str: string; const Language: TLanguage = langDefault): TAllowState; static; end; { TAllowStateHelper } class function TAllowStateHelper.FromString(str: string; const Language: TLanguage): TAllowState; begin Result:=asWarn; //Default var Lang := Language.GetLanguage; for var state :=Low(TAllowState) to High(TAllowState) do if CompareText(str, state.ToString(Lang)) = 0 then Exit(state); end; function TAllowStateHelper.ToString(const Language: TLanguage): String; begin Result := Translate[Self].Text(Language); end;

It is tricky to do a generic helper class for Enumerations, since there is no constraint that will allow you to use enum operators. There are workarounds, but not pretty ones. As for having to use a constant table - why not use the actual type name? There is System.TypInfo function to convert an enum to a string which reflects the actual type name. http://docwiki.embarcadero.com/Libraries/Sydney/en/System.TypInfo.GetEnumName Result := GetEnumName(TypeInfo(TProjectType), Ord(Self)); There also is the reverse http://docwiki.embarcadero.com/Libraries/Sydney/en/System.TypInfo.GetEnumValue

@RDP1974 - I moved the post and delete the three "reposts". If you happened to post in the wrong category, ask a moderator to move it. Please don't do reposts/cross-posts.

Wrong floating point precision when choosing overloads https://quality.embarcadero.com/browse/RSP-27488 Reduction of precision from integer to single rather than double https://quality.embarcadero.com/browse/RSP-27499 Another case of silent reduction of precision https://quality.embarcadero.com/browse/RSP-27500

Can it be that some of the known FP expression precision issues come into play here?

It was based on this: https://stackoverflow.com/questions/12788870/conditionally-compile-units-for-fmx-or-vcl I never mix VCL and FMX form code in projects myself, but I guess the problem here is that the "defined" depends on FMX.Types already being in scope. My approach would probably be to use an interface or a proxy class to hide the actual VCL/FMX accesses.

No worries. The only benefit of custom draw is if the column title is wider than the actual column.

@Kas Ob. - The 32-bit IDE is running on WoW. My IDE crashes too. Out of memory or it simply hangs in an internal deadlock. Several times per day. But - it has never crashed or trashed my Windows 10 Enterprise 1909 system. My uptime is typically about a month, i.e. until the next security patches. RAD Studio, Visual Studio, VS Code, PowerShell 7, MS SQL Server Manager, MS SQL Server, a large number of remote desktops, Excel, Outlook, OneNote, Teams, Discord, Chrome with too many tabs, Apex SQL Diff, Beyond Compare, VirtualBox, and the invaluable Process Hacker. I was thinking of the software you write - if it has page file issues - you either have HW spec issues, or you have allocation strategy issues.

"suffered from potential degradation" ? Either you suffer, or it is entirely potential. "The guys" ?

If your software has issues with page file involvement - your machines are not up to spec.
