“simply” hold the refresh button and then tap on Request Desktop Site – How to Use WhatsApp on iPad

Posted by jpluimers on 2018/01/05

… simply hold the refresh button and then tap on Request Desktop Site. The page should refresh and you should be redirected to web.whatsapp.com and you should be looking at a QR code on the screen of your iPad.

If you know it’s “simply”.

Fixing PowerPoint Annoyances: When I double-click a .pps/.ppx file, the PowerPoint icon appear on the taskbar…

Posted by jpluimers on 2018/01/05

From [WayBack1. Presenting Your Presentation – Fixing PowerPoint Annoyances [Book]:

PowerPoint Opens Minimized

THE ANNOYANCE: I can’t get my presentation to open properly when I double-click it. I can see the PowerPoint icon on the taskbar, but it won’t maximize or restore. How can I view the presentation?

THE FIX: Your slide show is set to display on the secondary monitor, which is no longer attached to your computer. Open PowerPoint from Start → Program Files and select File → Open to open your presentation. Then select Slide Show → Set up Show and choose “Display slide show on primary monitor.”

Record helpers can do wonders for code clarity.

Posted by jpluimers on 2018/01/04

A few people recently discovered the beauty of record helpers:

Record helpers can help any value type (which includes enumerated types) so you can add functions to enumerations.

Class helpers can help class types.

There are no interface helpers and likely won’t be there for a long while.

Delphi inner scoping is undefined. Please Embarcadero/Idera, come up with a formal language definition for Delphi

Posted by jpluimers on 2018/01/04

[WayBack] Hi there, this is pure curiosity only; but this compiler behaviour seems odd to me. What do you think?… – Agustin Ortu – Google+

The problems start when you prefix the outer class which you have to when using inner consts ([WayBack] Oh nice. Feel free to QP. Fails at least in Delphi XE8. … – Jeroen Wiert Pluimers – Google+).

The big problem in both cases is a formal language specification. The lack of a formal language specification makes it very hard to predict the effect of use cases or generate them for testing.

So this post is yet another request: Please Embarcadero/Idera, come up with a formal language definition for Delphi.

Raspberry Pi | RTAndroid

Posted by jpluimers on 2018/01/03

Raspbyerry Pi 3 are very versatile. Not just for your light weight Linux installation or Windows 10 IoT, but also for Android experimentation.

On my research list is [WayBackRaspberry Pi | RTAndroid:

Raspberry Pi 3 This page provides a device-specific tutorial for installing RTAndroid on the Raspberry Pi 3 Model B. Single-board computing devices

It’s an Android 7 (codenamed Android N, now Android Nougat) distribution with Raspberry Pi images (nowadays Raspberry Pi 3, but should run on older as well). Which means you do not have to upgrade your phone to use more recent versions of Android to program against.

mappings between counters, structure and Task Manager columns – Memory Performance Information (Windows)

Posted by jpluimers on 2018/01/03

I copied the tables from [WayBackMemory Performance Information (Windows) as even Microsoft managed to let information “disappear” for EOL products (the en-US version already “disappeared”):

System Memory Performance Information

The following table associates memory object performance counters with the data returned by the memory performance functions in the MEMORYSTATUSEX, PERFORMANCE_INFORMATION, andPROCESS_MEMORY_COUNTERS_EX structures, and with the corresponding information displayed by Task Manager.

Michael Kaplan Obituary – Berkowitz-Kumin-Bookatz | Cleveland Heights OH (and a whole bunch of info in zero width Unicode stuff)

Posted by jpluimers on 2018/01/02

I totally missed the passing of Michael Scott Kaplan some 2 years ago, so a belated R.I.P. is in place.

Obituary for Michael Kaplan, Michael Scott Kaplan, 45, passed away Wednesday, October 21, 2015, in Redmond, WA, after a brave battle with MS for 25 years. He was a lead software developer for Microsoft.

Source: [WayBackMichael Kaplan Obituary – Berkowitz-Kumin-Bookatz | Cleveland Heights OH

Michael was the leading source on i18n, L10N, Unicode, sorting, normalisation and other things having to do with languages, representations and writing.

Besides that he was a really nice guy of which I enjoyed his MSDN materials.

Other people enjoy that too, so I’m glad his writings have been archived: [first archive.is, second archive.is, WayBackSorting it All Out: Archives

Reinstalling atom.io: getting the user-installed package list then re-installing it.

Posted by jpluimers on 2018/01/02

Sometimes your Atom installation gets so unstable that the quickest solution is a reinstall. For that you need to get a list of user-installed packages, then re-install them.

On Windows your Atom Package Manager apm is here (but not in the path), where the first is version specific and the latter the most recent version:

%LOCALAPPDAT%\atom\app-1.18.0\resources\cli\apm.cmd
%LOCALAPPDATA%\atom\bin\apm.cmd

On Mac OS X, it is here and in the path:

/usr/local/bin/apm
/Applications/Atom.app/Contents/Resources/app/apm/node_modules/.bin/apm

Save your packages:

apm list --installed --bare > package-list.txt

Install packages:

apm install --packages-file package-list.txt

For my own memory, the settings folders:

  • Windows: %USERPROFILE%\.atom
  • Mac OS X: ~/.atom

LAUNCHED https://uberpdf.org/

Posted by jpluimers on 2018/01/01

It is a lot (~300 megabyte compressed download!), but worth it.

Here are the links:

And the quote from [WayBack] LAUNCHED https://uberpdf.org/ … – Joe C. Hecht – Google+

LAUNCHED https://uberpdf.org/

337 MB of source and utils in 2,308 Files, 910 Folders before you build (not counting 3rd party source UberBuild downloads).

It’s a start, with much to come.It will get easier now that UberBuild is clean.

I will be updating the docs and website in the next few days.

Special thanks …

I already see room for improvement (such as a setup screen for extra compilers such as Delphi and Free Pascal to keep folks out of shell scripts and from hunting for help in the documentation).
