Setting your DNS servers manually – via – Tweakers

Posted by jpluimers on 2015/08/21

Interesting Dutch thread about a major ISP having DNS issues because of DDos attacks. Many messages to set your DNS servers manually on various operating systems, and a list of good DNS server alternatives. Recommended reading:

Dropbox adds u2f support … if you connect to it via Chrome. Using FIDO U2F. Easy with Plug-Up foldable key.

Posted by jpluimers on 2015/08/21

I like this: the plug-up affordable FIDO U2F Security Key by  HAPPLINK.

You could already use it for Google 2nd factor authentication (2FA) through Chrome. You can do this from your own applications for instance through the U2F reference implementation.

Now you can also as 2FA to DropBox, also through Chrome. And it is easy with the plug-up key (Thanks Kristian):

Uuuund… umgestellt. Das war ja einfach.

Es gibt andere Fido Token, die können mehr. Ich nehme dieses, das kostet fast nix und man kann die kaufen und verteilen wie Konfetti.

Or inside the Europe mainland, for instance in:

Excel: Set the printing order of worksheet pages; printing row/coumn headings

Posted by jpluimers on 2015/08/21

I keep forgetting these two settings, most likely because I hardly use spreadsheets that are both wide and tall.

First the print order

Basically there are two orders:

  • Prefer horizontal over vertical (Excel calls this “Over, then down”) so it prints columns first, then rows
  • Prefer top to bottom (Excel calls this “Down, then over”) so it prints rows first, then columns

Here is how to do it in Excel 2007 and up:

  1. Ensure your worksheet is active.
  2. Click the “Page Layout” tab.
  3. In the “Page Setup” group, click the “Dialog Box Launcher” on the bottom right of the group (this tiny icon: Dialog box launcher).
  4. In the “Page Setup” dialog that appears, click on the “Sheet” tab.
  5. Under “Page order”, select either of these two options (the preview will change, see the images below).
    1. Down, then over
    2. Over, then down
  6. Click OK to close the “Page order” dialog.

Then the row/colum headings

This is actually much easier, and also works this way from Excel 2007 and up:

  1. Ensure your worksheet is active.
  2. Click the “Page Layout” tab.
  3. In the “Sheet Options” group, under “Headings”, select the “Print” check box.
