[WayBack] Rebooting a Linux server unattended – twm’s blog:
/sbin/shutdown -r now
Simple, but I keep forgetting where Linux has short/long command options and short/long verbs.

7 Rules for Creativity Managers – YouTube
Posted by jpluimers on 2020/09/18
Interesting video explaining there is a lot of work to do around me, meaning I probably need more in stead of less people around me (:
- Nurture diversity: Creativity managers dislike brains being the same.
- Create markets: Creativity managers favor coopetition in networks.
- Rely on merits: Creativity managers embrace networks and gameplay.
- Make no predictions: Creativity managers keep many options open.
- Update the workplace: Creativity managers work the environment.
- Change constraints: Creativity managers optimize for exploration.
- Open boundaries: Creativity managers connect instead of protect.

Delphi: TInvokableClassRegistryHelper.GetInterfaceNamespace as the opposite of TInvokableClassRegistry.RegisterInterface
Posted by jpluimers on 2020/09/17
A while ago, I needed the opposite of InvRegistry.RegisterInterface(TypeInfo(MySoapInterfacePortType, 'urn:myURN', 'utf-8');, so instead of registering an interface with a namespace URN, obtain the URN by passing the interface inverting [WayBack] TInvokableClassRegistry.RegisterInterface.
This is the class helper I wrote:
type
TInvokableClassRegistryHelper = class helper for TInvokableClassRegistry
public
function GetInterfaceNamespace(Info: PTypeInfo): string;
end;
function TInvokableClassRegistryHelper.GetInterfaceNamespace(Info: PTypeInfo): string;
var
InfoGuid: TGUID;
begin
// call like `Result := InvRegistry.GetInterfaceNamespace(TypeInfo(MySoapInterfaceType));`
InfoGuid := GetTypeData(Info)^.Guid; // uses TypInfo; see https://stackoverflow.com/questions/8439246/is-it-possible-to-get-the-value-of-a-guid-on-an-interface-using-rtti
Result := GetNamespaceByGUID(InfoGuid);
end;
It would have been a lot easier if TInvokableClassRegistry.GetIntfIndex has been public, because then [WayBack]TInvokableClassRegistry.GetRegInterfaceEntry could have been used.

FireDAC can do DBMS back-end conditional SQL via Conditional Substitution
Posted by jpluimers on 2020/09/17
Though the field-types mentioned in the problem and solution are equal (so either is wrong), the solution in [WayBack] I have a little problem with FireDAC and the TStringField and TWideStringField design time generation… – Juan C. Cilleruelo – Google+ pointed out by Jeff Weir is interesting: FireDAC supports conditionals that depend on the DBMS back-end, so you can differentiate between them.
The feature is called Conditional Substitution and has been present ever since AnyDAC (which got bought by Embarcadero, transformed into FireDAC, then after Idera bought Embarcadero, the main developer got pink-slipped).
The AnyDAC documentation is in the wayback machine, though you have to disable the onload event in order to read it.
The [Archive.is] XE5: Preprocessing Command Text (FireDAC) – RAD Studio documentation is not much different from the current state [Archive.is].
More background reading is at [WayBack] www.freepascal.org/~michael/articles/anydac2/anydac2.pdf and Cary Jensen covered it in his 2017 course on FireDAC of which you can see the free ToC.
Example from that thread:
SELECT ART.CD_ITEM ,
ART.CD_FAMILY ,
ART.CD_CATALOGUE ,
CAT.DS_CATALOGUE ,
FAM.DS_FAMILY ,
{IF MSSQL}
CASE WHEN EXISTS(SELECT 1 FROM CONFIGURATIONS COM WHERE COM.CD_PARENT = ART.CD_ITEM)
THEN CAST('Y' AS NVARCHAR)
ELSE CAST('N' AS NVARCHAR)
END HAS_CONFIGURATION ,
{fi}
{IF FIREBIRD}
CASE WHEN EXISTS(SELECT 1 FROM CONFIGURATIONS COM WHERE COM.CD_PARENT = ART.CD_ITEM)
THEN 'Y'
ELSE 'N'
END HAS_CONFIGURATION ,
{fi}
ART.DS_ITEM ,
ART.CD_TAX ,
TAX.DS_TAX ,
TAX.PRC_TAX ,
...
Given the problem statement, the casts likely should have been VARCHAR instead of NVARCHAR, but the construct can be very powerful.

A thread written by @SwiftOnSecurity
Posted by jpluimers on 2020/09/16
[WayBack] A thread written by @SwiftOnSecurity:
Corporate purchasing and policies make funding open source Literally Impossible.
Nothing’s going to change until you make them pay you.
Someone filed a bug?
Support contract.Someone wants a feature?
Support contract.It’s literally easier to pay you $1500/yr than $25 once.
Edit: since Threader/Threader_app died, I archived the Twitter thread at Archive.today.
And much more: worth a long read.
Via another interesting post: [WayBack] Idea for FOSS projects. Register your project/product name as a trademark and only use it for official, stable releases. Have a different name for your … – Jan Wildeboer – Google+
Idea for FOSS projects. Register your project/product name as a trademark and only use it for official, stable releases. Have a different name for your not-(yet)-stable Code.
Put trademark agreements in place. Everyone who uses your trademarked name for services based on your code has to pay. Everybody using the non-stable code is free to do so, but cannot use your trademarked name.
With lots of interesting comments:
- Jan Wildeboer
+Andreas Kahler because when you don’t allow use without pay you are violating the open source principles.
-
You just don’t allow the use of the trademarks. That’s perfectly fine with FOSS, e.g. with GPLv3: “you may […] supplement the terms of this License with terms: […] Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks”. See opensource.google.com – Trademarks in Open Source – opensource.google.com
-
+Andreas Kahler Yep. That’s how we work at Red Hat ;)
-
Alan Cox+1It’s how most distros work – it can be a problem though because you then control how the mark is used and without care it becomes a blocker. Eg it’s really hard to ship Unbuntu based stuff because you can’t modify Ubuntu and call it Ubuntu (which is fair enough) , but for cloud images – problem.
-
+Alan Cox That’s why it IMHO makes more sense for projects/products.
- Jan Wildeboer+1
+Torsten Kleinz … Setting up a new provider at any medium to big company is a big, lengthy and horrifyingly complex process.
