Dartbord Oche distances

The sport originates from the UK, so all measurements are in feet and inches. Let’s convert these correctly.

1 foot = 12 inch, 1 inch = 25,4 mm.

From the floor to the center of the Bull’s Eye:
5 feet. 8 inches = 68 inches = 1727,2 mm

From the front of the dartboard to the Oche / throwing line:
7 feet 9 1/4 inches = 93,25 inches = 2368,55 mm

Most websites will mention 1,73m and 2,37m, but as you can see this is not quite right.
Now, let’s add some math:

As good old Pythagoras says: “a2 + b2 = c2”, so:

5610029,1025 + 2983219,84 = 8593248,9425 and get the square root from this last one gives us:

2931,424387989566 !

So, our bullseye – oche distance should be 293,14 cm long to test the measurement diagonally.

The more you know…
Have a nice day!

Forget NAS login

Connected to a NAS, like Synology SMB Service, and clicked ‘remember my credentials’? Sure, that makes it easy whenever you want to go back to that same shared folder, but now what happens if you want to connect using a different user, with different rights to the share?
You would have to remove the exisiting connection first, and make sure Windows 11 forgets how to connect to that Server/NAS/Share. So what do you do?

  1. In your Windows Start menu, search for “Credential Manager”.
  2. In the “Windows Credentials” section, remove any stored credentials referencing the share, network drives or similar:
  3. Open the details with the ‘arrow down’ and click “Remove”.
  4. Repeat these steps until you remove all of the credentials associated with the NAS.

Now you can reconnect to your share and use the correct login.
Have a nice day!

Pin document to taskbar in Windows 11

Same problem as this one?
” under Windows 10 I could drag & drop any file (e.g. docx or xlsx) to the Word/Excel icon, which is pinned on my taskbar. When righ-clicking on the Excel icon, I could see my pinned Excel files. Same with Word: I saw all my pinned documents. Windows 11 doesn’t let me drag & drop files to the pinned Microsoft App in the taskbar anymore. Please note, it is not about pinning the Excel app to my taskbar or pinning a document as an app to the taskbar: it is about pinning a DOCUMENT to the pinned Mircosoft app. “

The answer:

Skip Thunderbird calendar item summary

Since TB91 behaviour for opening an item in your Thunderbird Lightning calendar has changed from ‘edit item’ to ‘view summary’. Yes, you can click ‘edit’ or hit enter, but it just adds another step to an operation that should be default, or at least be a preference you can set.

So Google to the rescue… read this, this, this (text below) and this… and solve the problem just like we solved the transparent items issue.
