How much RAM for Macbook Pro M4 to Run RAD Studio 12?
Lars Fosdal replied to amit's topic in General Help
Apple's RAM and disk prices are ridiculous, but personally I'd go for at least 24GB and 1TB. My MBP M1 has 32GB/2TB. -
Looks fixed now.

IMO, if you need multiple values for a field, you should use a list element. Duplicate key/value pairs in JSON just doesn't make sense. https://JsonLint.com does not like them either.

Delphi 11.1 + patches - No debug source / breakpoints?
Lars Fosdal replied to Lars Fosdal's topic in Delphi IDE and APIs
Sorry, no updates. Not using Delphi much, except from small utils. Haven't checked on the problem since 12.3. -
Option to set read topic on Unread Content list
Lars Fosdal replied to ŁukaszDe's topic in Community Management
AFAIK, no. You could run it through an RSS reader. Perhaps there is one that can ignore topics the way you desire? -

Lars Fosdal replied to ŁukaszDe's topic in Community Management
@ŁukaszDe You find a topic uninteresting, but it keeps reappearing? Have you tried the "Ignore this topic" for a thread you don't want to read again? -
RAD Studio 12.3 patch available - April 2025
Lars Fosdal replied to Roger Cigol's topic in Tips / Blogs / Tutorials / Videos
Yeah, THAT surfaced the dreaded error [dcc64 Error] NonNullableConstraint.dpr(41): Type parameter 'T' must be a non-nullable value type Half-baked patches are no fun. Edit - Also noticed that the Error ID is lost when using MSBuild. -
RAD Studio 12.3 patch available - April 2025
Lars Fosdal replied to Roger Cigol's topic in Tips / Blogs / Tutorials / Videos
@Anders Melander I just tried my example code which failed before the April patch in the 64-bit IDE, targeting 64-bit Windows. It no longer stops compiling. program NonNullableConstraint; {$APPTYPE CONSOLE} {$R *.res} uses System.SysUtils; type TMyClass = class function Select<T:Record>(const selector: string):TArray<T>; end; TNotifcationRow = record const Query = 'SELECT * FROM v_server_notifications'; public Id: Integer; Name: String; Data: String; ByWho: String; CreatedWhen: TDateTime; function DataAsId: Integer; end; TServerNotificationArray = TArray<TNotifcationRow>; { TMyClass } function TMyClass.Select<T>(const selector: string): TArray<T>; begin end; procedure Test; var MyClass: TMyClass; Res: TServerNotificationArray; begin MyClass := TMyClass.Create; Res := MyClass.Select<TNotifcationRow>('foo'); // <- E2512 Type parameter 'T' must be a non-nullable value type end; { TNotifcationRow } function TNotifcationRow.DataAsId: Integer; begin Result := 0; end; begin try Test; except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; end. -
RAD Studio 12.3 patch available - April 2025
Lars Fosdal replied to Roger Cigol's topic in Tips / Blogs / Tutorials / Videos
It is fixed. It is no longer necessary to remove the record constraint to avoid the non-nullable type error. Edit: Woops - missed that 64-bit thing... do you mean the 64-bit target, or the 64-bit compiler? -
You can reserve a video against embedding, so that might be a factor?

Recommended string format to work with UTF-8 databases
Lars Fosdal replied to Bruce Eglington's topic in Databases
Correct me if I'm wrong - but isn't the Delphi String automatically converted to/from UTF-8 (or other native db string formats) by FireDAC / Driver? -
AI Rewrite and COBOL Port Announced for Immediate Development
Lars Fosdal replied to dummzeuch's topic in GExperts
Why convert when you can enjoy the verbosity and indentation in all its glory? https://www.rocketsoftware.com/en-us/products/cobol/visual-cobol 🙂 -
I use PowerShell + dbatools module to do backups and restores, as well as check for space, database schema sync, check contents of DB and run scripts, etc.

Is it worth building desktop applications with all these web frameworks?
Lars Fosdal replied to Rolphy Reyes's topic in Project Planning and -Management
Considering every major ERP vendor is moving to cloud, I would say that the trend is "no". However, these are typically enterprise sized ERP systems. There may be a niche for small shop owner ERPs - but there are already tons of these out there, and even some of those are cloud based. As soon as you exceed a single user, you are in database territory, and when you talk mobile apps, you definitively are in web service country. I would suggest that you really research your intended target audience to see if there is a gap where a desktop app could fill a need. I would also suggest that you narrow down and "modularize" your functionality, because the concepts of ERP systems and their near relatives are REALLY far reaching. You may suddenly find yourself in Tax, CRM, HR & Salary, document management, EDI and WMS territory.
