Some quick links on Korian in The Netherlands as they were/are? buying a maze construction of care companies that were on the edge of bankruptcy

Posted by jpluimers on 2020/04/16

A few quick notes, so I at least have some links.

According to the ACM decision PDF, BluePrint Group B.V. and it’s subsidiaries, including de Statenhof in Leiden, were on the verge of bankruptcy in January 2020, and the Korian SA owned structure is supposed to save them.

Edit 20200424

The central phone number of ECR the statenhof (+31883280110) did not get answered for a few days and has now been disconnected by the phone provider. The phone number now listed at Google is +31885057000 which gets you to Ontzorgd Wonen. When being transferred to the Statenhof, you consistently get an “in use” tone.

The old phone number is still listed in many places, like for instance [WayBack] www.latest.facebook.com/DeStatenhof and the email signatures of their personnel. The new phone number is also at [WayBack] De Statenhof Leiden | Wonen met zorg | Ontzorgd Wonen Groep.

Family relations of ECR de Statenhof

These lists are not complete, as I focus on ECR the Statenhof in oder to understand where it will be in a future structure.

LBS008AE and LBS005AE-R2, 10-100 Switches USB powered – Black Box

Posted by jpluimers on 2020/04/16

These are cool devices: the [WayBack] LBS008AE and LBS005AE-R2, 10-100 Switches USB powered – Black Box.

Both are the size of a Raspberry Pi and USB powered.

The first is 8-port, the second 5-port. Ideal for a stack of Pis.

There are 5V powered 8-port Gigabyte switches from other vendors as well at around `1A (effectively using ~5W), but they are bigger.

sed double expression: match, replace in one line, overwrite file

Posted by jpluimers on 2020/04/15

A while ago, I needed to conditionally replace in files, so I used sed and a regular expression, though usually I dislike those.

However, since the system had a very basic install, there was not much choice.

Luckily back then, my Google foo returned these:

This allowed me to do a double expression (the first matches a pattern, the second performs the actual replacement within the matching lines).

In case my Google foo in the future fails:

## https://robots.thoughtbot.com/sed-102-replace-in-place
## -i causes no backup to be saved, but does in-place replacement
## since we run under git, we can always restore
## combined with a double expression (the first matches, the second executes) this is very powerful
sed -i -e '/#.*AVOID_DAILY_AUTOCOMMITS=.*$/s/^.//' /etc/etckeeper/etckeeper.conf && git diff | more

Binary search for finding problematic versions: install a specific version in homebrew and git bisect

Posted by jpluimers on 2020/04/14

I’ve used these excellent posts to find out which youtube-dl version started to exhibit troublesome NPO downloads, then later find the actual failing commit:

Why the effort? I needed an as recent as possible youtube-dl working on as many sites as possible because of some work preparation.

The first link is very important because brew versions and alternatives have stopped working some 6 years ago, even though they turn up high on Google searches for brew install specific version. Hence the quote from the first link:

Installing software packages on Mac is very easy with homebrew. You typically get the latest version, however often in production you do not have the latest version of a software package. Another use case is when you upgrade to the latest and you find out there is bug which blocks you doing something. In this case you would like to downgrade to the previous version until the bug is fixed.In both cases you need to install a specific version of a software package with homebrew on your Mac, which tends to be not that trivial. There is a lot of discussion about this on stackoverflow but some of them are outdated based on brew versions which is not available anymore.

Create a large file filled with zeros on Linux – twm’s blog

Posted by jpluimers on 2020/04/13

Interesting read as there are at least 3 options of which I only knew the first (dd): [WayBack]  Create a large file filled with zeros on Linux – twm’s blog.

  • dd (fully allocated storage; zeros, random or another data source)
  • truncate (sparse storage; always gets zeros)
  • fallocate (fully allocated storage; always gets zeros)

Common SMTP message size limits

Posted by jpluimers on 2020/04/08

After a 2018 discussion with a “zorgkantoor” (Dutch for office that arranges for special long term health care needs, successor of AWBZ) about their very low (10 megabyte) SMTP message size limit – even though they expect scanned PDF documents.

Their web-care team posed this limit as normal, so I made a list of limits in their peer group, common world-wide and well-ranked Dutch internet providers.

My plan is to check the progression of these limits over time.

Note these are the bruto message sizes including encoded attachments. Since encoding in [WayBack] MIME Base64 – Wikipedia has a overhead of at least 37% (encoded size is at least 1.37 the original size), the unencoded maximum size is less than 73% of what is listed below.

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 apple.com 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/Archive.is] 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.
