Delphi Conference 2018 – Barnsten.com

Posted by jpluimers on 2020/02/25

I missed this one, so I was glad I archived it because I was curious for Daan van der Werf – Delphi op de werkvloer “Groothandel & Magazijn”.

So here it is: [WayBack] Delphi Conference 2018 – Barnsten.com, with fixed and archived links where possible.

Presentations and code from the Delphi Conference 2018

One Story Per “Sprint” – John Cutler – Medium

Posted by jpluimers on 2020/02/25

Food for thought: what is the hardest thing in your sprints, why, can you make it less hard?

[WayBack] One Story Per “Sprint” – John Cutler – Medium:

Delivering a “potentially releasable increment” after N days is not “hard”. It is not rocket science. (Almost) any team can do it.

Via: [WayBack] One Story Per “Sprint” – John Cutler – Medium – Marjan Venema – Google+

it is not funny to always feel behind; that it actually is detrimental to productivity to focus solely on efficiency, working hard and being hero’s; that it might be a good idea to start with changing your perspective and doing something which has a chance of being successful (doing a single story) and build from there.

It is not about looking busy, but it is about getting things done without having any fears.

TInterlockedHelper for Delphi interfaces: Spring.Reactive.pas

Posted by jpluimers on 2020/02/25

Reminder so self: [WayBack] sglienke / Spring4D / source / Source / Reactive / Spring.Reactive.pas — Bitbucket fragments:

type
  TInterlocked = SyncObjs.TInterlocked;
  TInterlockedHelper = class helper for TInterlocked // TODO: move to Spring.pas
    class function CompareExchange<T: IInterface>(var Target: T; const Value, Comparand: T): T; overload; static;
    class function Exchange<T: IInterface>(var Target: T; const Value: T): T; overload; static;
  end;


{$REGION 'TInterlockedHelper'}

class function TInterlockedHelper.CompareExchange<T>(var Target: T;
  const Value, Comparand: T): T;
begin
  Result := Default(T);
  PPointer(@Result)^ := CompareExchange(PPointer(@Target)^, PPointer(@Value)^, PPointer(@Comparand)^);
  if PPointer(@Result)^ = PPointer(@Comparand)^ then
  begin
    if Assigned(Value) then
      Value._AddRef;
  end
  else
    if Assigned(Result) then
      Result._AddRef;
end;

class function TInterlockedHelper.Exchange<T>(var Target: T;
  const Value: T): T;
begin
  Result := Default(T);
  PPointer(@Result)^ := Exchange(PPointer(@Target)^, PPointer(@Value)^);
  if Assigned(Value) then
    Value._AddRef;
end;

{$ENDREGION}a
