Cool new Twitter account that warns about a free book when it appears: Packt Free Learning (@packtfreebook) | Twitter

Posted by jpluimers on 2019/06/25

Packt free books

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.

EU versus USA Packt prices

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.

missing TPopupMenu feature: checking for visibility

Posted by jpluimers on 2019/06/25

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.ismissing TPopupMenu features? – Google Groups.

Now you can hook the [WayBackTControl.OnContextPopup Event for a [WayBackTPopupMenu activation, and the custom Windows messages CM_MENUCLOSED, CM_ENTERMENULOOP and CM_EXITMENULOOP to monitor the state of the popup menu.

Enable remote desktop on Windows – SystemPropertiesRemote.exe

Posted by jpluimers on 2019/06/24

The easiest way to enable remote desktop access on Windows is by running SystemPropertiesRemote.exe.

There are alternatives using the command prompt that edit registry settings and network firewall in the links below, but they are all more cumbersome.

Links mostly via enable remote desktop on windows – Google Search

I need to check out:

  • which of the above are really old
  • how to find out if WinRM is enabled
  • see if this can be done over WinRM
  • see if this can be done with PSShell
  • see if PowerShell is a good successor to the now deprecated netsh
    • you want to enable the remote desktop group in a language and windows version neutral way, not just port 3389

Some registry entries:
