It has been a while after my last post about me having cancer. No, I am not giving up. But I am having the regular fear of the upcoming checks: did the metastases return, or do I have the luck to outlive some 30% of my peer group.
The last metastases surgery has been slightly more than a year ago. A year from now, that percentage hopefully will be 50% and slowly increase over time until about 90% in some 9 years from now.
At year’s end, I will know for sure.
Below are some links on, mostly Dutch but with English abstract, articles about the mental side of having cancer, or having survived it for now.

[Wayback/Archive] Moving things – YouTube is a short remix of the YouTube short video [Wayback/Archive] Based on your ideas! What else shall I design? – YouTube based on an idea from [Wayback/Archive] cdaylward (Charles D. Aylward) · GitHub.
Basically it is the opposite of the Eye-Fi: you op a micro–SD card in the board, then mount the board on an ESP32 one with Wi-Fi, power up the combo, then can you can access the files via your Wi-Fi network.
This makes it a lot easier to transfer files to for instance a 3D printer. For some of these printers in order to refresh the content, you have to pull out then re-insert the microSD/adapter/ESP32-board contraption.
Hopefully by now the tutorial mentioned at the end of the video has been published online.
Images grabbed from the above video:

Preview on MacOS has a great set of zoom keyboard shortcuts. They all feel very natural, and unlike Adobe Acrobat or Adobe Reader, include shortcuts for one-page view and two-page view.
The screenshot on the right shows all of them in the menu, as somehow a simple Google Search did only reveal a page documenting a limited set of them. So further below, I will document the list.
The same holds for Adobe Reader and Adobe Acrobat: it’s hard to find a good list of all view related keyboard shortcuts even when trying multiple times.
I did find a few pages though with partial lists of keyboard shortcuts, so I gobbled them together below in another table.
Preview View menu keyboard shortcuts
(I removed all entries that did not have a keyboard shortcut)

I edited an answer to [Wayback/Archive] git – View rendered output of a gist? – Stack Overflow¹ and it appears that Stack Overflow / Stack Exchange have introduced a WYSIWYG editor of which the help still points to the old Markdown editor.
[Wayback/Archive] Markdown Editing Help – Stack Overflow
The problem is that the new WYSIWYG editor generates Markdown that in part cannot be properly rendered by the Markdown question / answer viewer (for instance, strikethrough is emitted as by the WYSIWYG editor in Markdown as ˜˜strikethrough˜˜ but the viewer can only render <s>strikethrough</s>.
Since their meta sites are toxic as hell:
is there anyone that knows where to find the source code of the Stack Overflow / Stack Exchange WYSIWYG editor?
Thanks!
From the links below, I doubt the StackExchange pagedown repository is the one as it has been unmaintained since 2012 and the WYSIWYG editor is still in beta: I would have expected bug fixes over time, but there aren’t. Or maybe that all is caused by the toxicity on their platform?
This was my queste for information and some of the links I found:

Lot’s of power supplies on [Wayback/Archive] MikroTik Routers and Wireless – Products, most (except the internal ones) I listed below grouped by output voltage and amperage (and wattage which I rounded down).
I didn’t realise there were so many and that there basically is no consistent naming scheme.

Likely what I want is not possible because of CORS or CSP (both security features, often mixed up in writings), but just in case below are some links I found.
The problem at hand was that I wanted to use the functionality of a site like [Wayback/Archive] Redirect Checker | Check your Statuscode 301 vs 302, but on the client side because sometimes redirects depend on locality (for example, but not limited to, AliExpress sites).
Thinks like these fail with CSP errors like Refused to connect to 'https://t.co/Ui4Wmesq1j' because it violates the following Content Security Policy directive: "connect-src chrome://resources chrome://theme 'self'".:
var xhr = new XMLHttpRequest();
xhr.onload = function() {
if (this.status < 400 && this.status >= 300) {
console.log('request redirects to ' + this.getResponseHeader("Location"));
} else {
console.log('request does not redirect');
}
}
xhr.open('HEAD', 'https://t.co/Ui4Wmesq1j', true);
xhr.send();
Links – many of them mentioning CORS, but few CSP:

Via the below BSKY post (some call these skeets), I learned about the CSS feature “font-variant-numeric: tabular-nums” which switches on the OpenType tnum feature of fonts that support it.
More and more supports these tabular numerics, which makes all digits equally wide making both numbers in tables and lists as well as quickly changing numbers like sub-second timers a lot easier to read.
Failing example due to WordPress ditching the style

If I ever run into a Cloudflare hosted site, I should try fiddling with the site-specific /cdn-cgi/ endpoint that Cloudflare automagically adds: [Wayback/Archive] /cdn-cgi/ endpoint · Cloudflare Fundamentals docs
Via [Wayback/Archive] Dr. Christopher Kunz: “I didn’t know this and it migh…” – chaos.social
I didn’t know this and it might really be handy with debugging weird Cloudflare issues (like pages not loading): Cloudflare adds an URL endpoint to each domain that they host, /cdn-cgi. It has, amongst others, the /cdn-cgi/trace endpoint that shows which data center services your request. More docs here: https://developers.cloudflare.com/fund
The/cdn-cgi/trace endpoint is documented at [Wayback/Archive] Gathering information for troubleshooting sites · Cloudflare Support docs
