Having cancer is not a fight or a battle, it is about having luck or misfortune

Posted by jpluimers on 2021/12/10

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.

Not doing CSS much, I was this years old to learn about “font-variant-numeric: tabular-nums”

Posted by jpluimers on 2026/08/25

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

This could help debugging issues with Cloudflare hosted sites: /cdn-cgi/ endpoint · Cloudflare Fundamentals docs

Posted by jpluimers on 2026/08/24

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

Bookmarklets for going from the Wayback Machine to Archive Today

Posted by jpluimers on 2026/08/20

To ease my blogging, I wrote two more Bookmarklets that help me navigate to or save from a Wayback machine archived page to Archive Today.

A key thing I learned over the past 2+ decades is that “the cloud” (i.e. cloud computing) is “just someone else’s computer” which tends to be unavailable right when you need it no matter the applicable service-level agreement.

Which means that a long while ago, I switched to archiving external links to both the Wayback machine and Archive Today.

Since the Wayback machine is my primary, it helps to have Bookmarklets to go from such an archived page to the equivalent one on Archive Today, or even save it if it isn’t there.

So I made two more Bookmarklets which I will illustrate using the example.org based links https://example.org and http://example.org:

Fixed my Windows Update Error 0x800705b9 on Windows 11 25H2: Reset Windows Update Components batch files

Posted by jpluimers on 2026/08/19

I created the gist [Wayback/Archive] Fixed my Windows Update Error 0x800705b9 on Windows 11 25H2: Reset Windows Update Components batch files from https://kimiyoya.com/windows-update-error-0x800705b9-fix-en/ and https://www.elevenforum.com/t/reset-windows-update-in-windows-11.3808/ · GitHub

In it, the first batch file solved the Windows Update Error 0x800705b9 I had on a Windows 11 25H2 machine, probably with the root cause that the C: drive had become full during running updates.

Standard measures failed:

Some LoRaWAN notes to decide buy or build?

Posted by jpluimers on 2026/08/19

A long time ago, I volunteered to participate in the first Dutch LoRaWAN initiative but somehow no more follow-up after the first initial 2015 email exchange.

Now that I have reached peak recovery of all my cancer treatments and LoRaWAN is far more available there is some room for experimentation.
