Outlook 2013 cannot logon to gmail any more

Posted by jpluimers on 2019/09/20

A problem on a PC I did not use often: as of a sudden, Outlook 2013 could not access a gmail account any more.

Luckily, Outlook showed me this message in a dialog box:

Please log in via your web browser: https://support.google.com/mail/accounts/answer/78754 (Failure)

This directed me to [WayBack] Use IMAP to check Gmail on other email clients – Gmail Help

In turn that pointed to [WayBack] Let less secure apps access your account – Google Account Help

Finally that one indicated the configuration page changed to https://myaccount.google.com/lesssecureapps

This is similar to the cause of “the user name or password for imap.gmail is incorrect” – iPad, iPod or iPhone with iOS < 7

It all comes down to gmail forcing OAUTH2: [WayBack] tls – Why doesn’t outlook 2013 meet modern security standards? – Information Security Stack Exchange

Google YouTube Keyboard Shortcuts – Windows – U-M Google

Posted by jpluimers on 2019/09/20

Cool table via the University of Michigan’s Google Apps for Education [Archive.is/WayBack]:

Note: These shortcuts will only work when the video player is in focus. To move the focus try pressing the spacebar to pause and then play the video.

Action Shortcut
Toggle play/pause the video
 k or Spacebar
Go back 5 seconds
 Left arrow
Go back 10 seconds
 j
Go forward 5 seconds
 Right arrow
Go forward 10 seconds
 l
Skip to a particular section of the video (e.g., 5 goes to the video midpoint)
 Numbers 1-9 (not the keypad numbers)
Restart video
 0 (not the keypad number)
Go to Full Screen mode f
Exit Full Screen mode
 Escape
Go to beginning of video
 Home
Go to end of video
 End
Increase volume 5%
 Up arrow
Decrease volume 5%
 Down arrow
Increase speed
 Shift+> (may not work in all browsers)
Decrease speed
 Shift+< (may not work in all browsers)
Move forward 1 frame when video is paused . (period)
Move backward 1 frame when video is paused , (comma)
Mute/unmute video m
Turn captions on/off c

Dave’s Development Blog – Using CodeSite on interfaced objects

Posted by jpluimers on 2019/09/20

Reminder to self: [WayBack] Dave’s Development Blog – Using CodeSite on interfaced objects:

Note to self…

If using CodeSite to log Constructor and Destructor behaviour on interfaced objects, make sure its the first unit in the project so that it is the first unit initialised AND THE LAST unit finalised!

This will save you hours and hours hunting down shutdown AVs 🙁

Or in my projects, the uses list in the Delphi project should be this order:

  1. FastMM4Bootstrap
  2. CodeSite

Hi, We need to implement a functionality in our VCL application where the user…

Posted by jpluimers on 2019/09/19

In recent Delphi versions one is encouraged to use the routines from System.NetEncoding. Also Soap.EncdDecd is only a wrapper to them. Even if you use the stream based implementations the whole stream is read into a TBytes. So no real gain there any more.

LED Voltage Drops

Posted by jpluimers on 2019/09/19

[WayBack] Dangerous Prototypes: Basic Light Emitting Diode guide – Voltage drop or forward voltage has a nice table of common LED types:

You can also measure them yourself using most multi-meters have setting for that as described in [WayBack] Easy way to figure out a LED’s Vf in order to pick an appropriate resistor – Electrical Engineering Stack Exchange

You can also measure yourself, but my Proster VC99 multi-meter (cheap, but functions well, see for instance the review in [WayBack] MagPi issue 43) can measure voltage drop, so I’ve measured some LEDs from old PC cases:

  • Red: 1.8 V
  • Yellow: 1.8 V
  • Green: 1.8 V
  • Blue: does not measure

Given that they all have the same voltage drop, I made the below table with some resistor values to get the same current through them on various voltages (3.3V, 5V and 12V) based on Standard resistor values.

Note anything less than 20mA of current usually is OK (though 20mA often is on the bright side).

LED Colour Voltage drop (Vf) Total Voltage Remaining Voltage Resistance Ω Current mA Power mW
Any 1.8 5 3.2 220 14.55 46.55
Any 1.8 12 10.2 680 15.00 153.00
Any 1.8 3.3 1.5 100 15.00 22.50
Any 1.8 5 3.2 330 9.70 31.03
Any 1.8 12 10.2 1000 10.20 104.04
Any 1.8 3.3 1.5 150 10.00 15.00
Any 1.8 5 3.2 470 6.81 21.79
Any 1.8 12 10.2 1500 6.80 69.36
Any 1.8 3.3 1.5 220 6.82 10.23

Using Image Encoders and Decoders in Managed GDI+ | Microsoft Docs

Posted by jpluimers on 2019/09/17

I forgot who pointed me to this, but it will be useful the next time I need to do image export/import in .NET or GDI+ [WayBack] Using Image Encoders and Decoders in Managed GDI+ | Microsoft Docs.

GDI+ has built-in encoders and decoders that support the following file types:

  • BMP
  • GIF
  • JPEG
  • PNG
  • TIFF

GDI+ also has built-in decoders that support the following file types:

  • WMF
  • EMF
  • ICON
