Create a custom paper size for printing on Mac – Apple Support

Posted by jpluimers on 2020/04/06

Since a search for this does not result in any hits on the web site (for instance not “To create a new paper size based on an existing size, select a paper size in the list, then click Duplicate.”), I have quoted it in full.

The main reason: “to change the name, double-click, then type a new name”

I needed this to specify A0 size, in inches, which was hard to find exact dimensions with more than 1 decimal digit, but luckily- unlike ISO 216 – Wikipedia:

And there is the millimeter specs (and way more) at [WayBack] A4 paper format / International standard paper sizes.

The quote from [WayBack/] Create a custom paper size for printing on Mac – Apple Support:

Create a custom paper size

If you want to create a document that has a unique size, such as an envelope or card, first see if the paper size appears in the Paper Size pop-up menu. If not, you can create your own custom paper size. Custom paper sizes aren’t available for some printers or for all apps.

Note: The following options might not be available for your printer or app. If these instructions differ from what you see onscreen, refer to the documentation that came with the app you’re using.

  1. Choose File > Print. If you see a Show Details button, click it to show all available options.
  2. Click the Paper Size pop-up menu, then choose Manage Custom Sizes.
  3. Click the Add button  to add a new paper size, then specify the paper size you want.
    Click the Add button to add a new paper size. To change the name of your custom paper size, double-click the name, then type a new one. Choose a printer from the pop-up menu to use its standard margins, or enter custom values in the fields below.

To create a new paper size based on an existing size, select a paper size in the list, then click Duplicate.

To print to a custom paper size, choose it from the Paper Size pop-up menu in the Print dialog (choose File > Print). To set a document size to a custom paper size, choose it from the Paper Size pop-up menu in the Page Setup dialog (choose File > Page Setup).

Tip: If a document is printing with incorrect margins or clipped text, try this: click the Non-Printable Area pop-up menu, choose User Defined, then enter zero for the nonprintable margins. In some cases this allows the document margins to print as expected.

Why the current Coronavirus (SARS-Cov-2) is so much nastier than the first SARS

Posted by jpluimers on 2020/04/06

A very interesting thread unfolded by ThreadreaderApp (via [] Andrea on Twitter: “Interesting read!… “) starts at [] Peter Kolchinsky on Twitter: “While not technically alive, there’s an evil genius to viruses that never ceases to amaze me. It’s one reason I became a virologist. A recent Nature paper reveal a remarkable trick SARS-Cov-2 learned that makes it nastier than the first SARS. Both viruses…”:

Posted by jpluimers on 2020/04/06

I found this in one of my logs a a while ago:

Error when executing EHLO command for domain on SMTP server
(554, ' (mxgmxus007) Nemesis ESMTP Service not available\nNo SMTP service\nBad DNS PTR resource record.\nFor explanation visit')

It means that / are among the strictest email handling providers I know. I don’t blame them: EHLO is at the start of an extended SMTP session.

At [WayBack] Error messages | GMX Postmaster it indicates:

5xy Bad DNS PTR resource record

Emails from your email server were rejected because the PTR Resource Record (PTR-RR) of your IP address does not follow our guidelines. Possible reasons for this can be:

Hoe gaan autistem om met de coronacirsis? 15-minuten interview met Karol Henke, Bianca Toeps en Chris Verlaan (@KarolHenke, @biancatoeps, #ChrisVerlaan)

Posted by jpluimers on 2020/04/06

Een voor mij belangrijke quote van Chris Verlaan:

Blijkbaar heb ik een bepaald aantal mensen in mijn omgeving nodig om te kunnen functioneren.

Zowel overprikkeling als onderprikkeling is voor veel mensen met autisme een probleem.

De overprikkeling is meestal veel makkelijker te onderkennen dan onderprikkelingen.

Dan 2 quotes van Bianca Toeps:

  • Probeer toch zoveel mogelijk structuur voor jezelf erin te brengen.
  • Wees niet te boos op iedereen.
  • Gun jezelf ook wat.

In mijn geval, herstellend van zowel endeldarmkanker als een burn-out: schenk aandacht aan zowel overprikkeling en onderprikkeling.

En dan de laatste quotes, van Karol Henke:

  • Zoek de rust op
  • Zoek de regelmaat op
  • Check de website [WayBack]
  • De autisme hulplijn 030 22 99 800 (elke werkdag bezeg door 20 vrijwilligers van 10:00 tot 14:00; vanuit het buitenland +31302299800).
