Usually one free book each day, with some pauses when Packt Publishing runs other specials [WayBack] Packt Free Learning (@packtfreebook) | Twitter.
This account started on 20190621. Hopefully it lasts for a while, as it is a very easy reminder on when a new free book becomes available.
Maybe they will notify of other free specials as well; time will tell.
Hopefully, the WordPress Twitter binding will show the most recent one below by Packt – Wikipedia.
Note that since a month or two, the Packt site asks me on a daily base to switch to their European site instead of to their USA site.
Avoid switching, as that incurs a high currency conversion cost. For example:
So that is a EUR/USD conversion factor of between 0.9 and 0.86 right (eBook 9/10 and paper+eBook 38.99/44.99).
Actually that’s not true: at the time of writing, the conversion is 0.78 which leaves a ~15% profit for just eBooks (0.9/0.78-1) and ~10% (0.86/0.78) margin for the Packt conversion. A tad high for my likings.

a method to detect when the menu was closed without a selection (i.e. none of the menuitem OnClick handlers fired). Add the unit below to your project and the form the popup menu is on will receive the custom messages defined in the unit when the menu appears or closes.
The solution by Peter Below in ExPopupList works from D5 on: [Archive.is] missing TPopupMenu features? – Google Groups.
Now you can hook the [WayBack] TControl.OnContextPopup Event for a [WayBack] TPopupMenu activation, and the custom Windows messages CM_MENUCLOSED, CM_ENTERMENULOOP and CM_EXITMENULOOP to monitor the state of the popup menu.

Learned a new thing today: you can change the line styles in PlantUML to these:
This in addition to the colour I already knew about. The order of these does not matter:
@startuml ' Make a dashed line, alternative syntax for ..> (*) -[dashed]-> "Write outline" ' Make line bold and use color name "Write outline" -[bold,#green]-> "Find example" ' Only change the color with hexadecimal RGB code "Find example" -[#ff00ff]-> "Write blog" ' Order of line style and color can be reversed "Write blog" -[#6666ff,dashed]-> "Publish" ' Use dotted line style "Publish" -[dotted]-> (*) @enduml

I like PlantUML a lot as it is an easy way to create even simple diagrams using plain text, for instance a simple Sequence Diagram like below.
Sometimes, you want to add comments because the way you build the diagram needs explanation that is not needed in the diagram itself. You can:
[Archive.is] Is it possible to comment out lines of diagram syntax? – PlantUML Q&A:
You can use quote like in the following example
@startuml
' This is a comment on a single line
Bob->Alice : hello
/' You quote by using slash-and-quote
to split your comments on several
lines '/

Interesting observation on [WayBack] How do you use the CLI version of GetIt Package Manager. I always get a “no items were found.” response. As usual, the EMBT wiki is total rubbish and do… – Graeme Geldenhuys – Google+.
What you need for GetItCmd, is to run rsvars.bat for your Delphi version first, which is exactly what [WayBack] Run-Dependend-rsvars-From-Path.bat – which I wrote a while ago – does.
I did not even know that there was a CLI equivalent of [WayBack] GetIt – RAD Studio , but it is there, totally undocumented: GetItCmd apart from two filename references on the French and German docwiki:
Apart from that, I could only find these links:
Another odd thing: rsvars.bat is also not documented, and has just one reference in the docwiki: [WayBack] Using CMake with C++ Builder – RAD Studio.
The use of rsvars.bat is simple: it sets the below environment variables (some older versions set less variables, like missing PLATFORM or PlatformSDK) for use with the IDE (bds32.exe), msbuild and GetIt.
BDS BDSINCLUDE BDSCOMMONDIR FrameworkDir FrameworkVersion FrameworkSDKDir PATH LANGDIR PLATFORM PlatformSDK
(some of these are set to empty to they at least exist)
Later on, Marco Cantu reacted
The command line version of GetIt is not stable, so it was never “promoted” to being a feature. It was a tentative feature, we likely removed the English doc, but translations remained — so having that documentation is kind of an error. We ship is as we use it, with a specific command that works and is safe. In other words, use it as your own risk, as it is not an official feature.
So apparently, the only way that GetIt works, is through a specific command in GetItCmd. From an architectural point of view that gives me a “lets get this tick on the feature matrix done no matter what the architectural consequences are” feeling.

I needed a solution inside a batch file for git similar to [WayBack] How to test if an executable exists in the %PATH% from a windows batch file? – Stack Overflow which became this:
where /q git || echo Cound not find git on the PATH %PATH%. && goto :eof
I could have expanded this to find the install location, but for now this is sufficient.
When it is needed, I should read [WayBack] Programmatically (not manually) finding the path where Git is installed on a Windows system – Stack Overflow

Reminder to self to try this out: [WayBack] Working in a team? DprojSplitter might be helpful! | The Art of Delphi Programming.
The most recent version (covering a wider range of Delphi versions) was at [WayBack] DprojSplitter for Delphi XE2 to XE6 available | The Art of Delphi Programming.
DprojSplitter handles the current build configuration and current plattform. In addition these settings are handled, too (found in CommonOptionStrs):
sDebugger_RunParams,
sDebugger_RemoteRunParams,
sDebugger_HostApplication,
sDebugger_RemotePath,
sDebugger_RemoteHost,
sDebugger_EnvVars,
sDebugger_SymTabs,
sDebugger_Launcher,
sDebugger_RemoteLauncher,
sDebugger_IncludeSystemVars,
sDebugger_UseLauncher,
sDebugger_UseRemoteLauncher,
sDebugger_CWD,
sDebugger_RemoteCWD,
sDebugger_RemoteDebug,
sDebugger_DebugSourcePath,
sDebugger_LoadAllSymbols,
sDebugger_LoadUnspecifiedSymbols,
sDebugger_SymbolSourcePath
Heck, you can even configure the ones to split: [WayBack] Configuring DprojSplitter to Your Needs | The Art of Delphi Programming

I need to re-read this: [WayBack] Pattern: Service Mesh
Via [WayBack] What is a Service Mesh? What is the purpose of Istio? – The Isoblog. /[Archive.is] What is a Service Mesh? What is the purpose of Istio in Kubernetes? … – Kristian Köhntopp – Google+:
An article by Phil Calçado explains the Container Pattern “Service Mesh” and why one would want that in a really nice way.
Phil uses early networking as an example, and explains how common functionality needed in all applications was abstracted out of the application code and moved into the network stack, forming the TCP flow control layer we have in todays networking.
A similar thing is happening with other functionality that all services that do a form of remote procedure call have to have, and we are moving this into a different layer. He then gives examples of the ongoing evolution of that layer, from Finagle and Proxygen through Synapse and Nerve, Prana, Eureka and Linkerd. Envoy and the resulting Istio project of CNCF are the current result of that development, but the topic is under research, still.
