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.

Take this cool example I extended from [Wayback/Archive] Thomas 🅰️🇨🇵 on Twitter: “#Typescript quizz What will be the value of result1 and result2 ?” which lacked alt-badge, so I [Wayback/Archive] responded with the image on the right that has alt-text.
Based on that, I added a bit of logging:
const a = undefined;
const result1 = a ?? 0 + 10;
const b = 100;
const result2 = b ?? 0 + 10;
console.log(result1);
console.log(result2);
Two questions:
- What is the output of both log lines?

ZeroTier looks interesting: [Wayback/Archive] ZeroTier | Global Area Networking.
Especially since:
- [Wayback/Archive] zerotier/ZeroTierOne: A Smart Ethernet Switch for Earth open source repository
- [Wayback/Archive] Pricing (Plan Basic: Free / ZeroTier Hosted Controller, 1 Admin, 25 Nodes, Unlimited Networks, Business SSO: n/a, Community Support)
- [Wayback/Archive] ZeroTier on MikroTik
MikroTik now joins Ubiquiti, Teltonika Networks, OpenWrt, and OPNsense on our list of supported 3rd party networking firmware and routers.
The first is unlike Tailscale.
Too bad it is not available as official pfSense package:

Boy have I been living under a stone, I wish I had known Little Snitch 2 decades ago (:
Little Snitch – Wikipedia:
Little Snitch is a host-based application firewall for macOS. It can be used to monitor applications, preventing or permitting them to connect to attached networks through advanced rules. It is produced and maintained by the Austrian firm Objective Development Software GmbH.
At the time of writing, it was at version 5.x, and it was introduced early this century.

A few years back this trick was shown to screw up %windir%\system32 [Wayback/Archive] Patrick Doyle on Twitter: “@SwiftOnSecurity @RoseAreaZero Delete any file in three easy steps: > takeown /F "example.ext" > icacls "example.ext" /grant "%USERNAME%":F > del "example.ext"“.
Like [Wayback/Archive] SwiftOnSecurity (@SwiftOnSecurity) / Twitter (see the long thread further below), I was expecting that Windows would either prevent you from doing this at all, or allow for easy recovery with System File Protection (now Source: Windows File Protection).
That didn’t prevent or recover it back then.
I wonder if that has been changed by now.
From the above Tweet:
Delete any file in three easy steps:
> takeown /F "example.ext"
> icacls "example.ext" /grant "%USERNAME%":F
> del "example.ext"

Cool to see what 3D printing plus a Raspberry Pi emulating a C64 can do [Wayback/Archive] I Built a Commodore 64 Laptop That Never Existed (PI + EMULATION) – The Portable 64 Concept Design – YouTube.
The Portable 64 with an original Commodore 64 joystick
However, published in December 2025 after Commodore had been resurrected from the C= brands, it would have been way cooler if was based on new Commodore 64 Ultimate hardware.
Maybe someone will do such a portable computer based on that hardware, or even better that it becomes available at [Wayback/Archive] Home | Commodore.

Cool post [Wayback/Archive] AbortController is your friend starting with
One of my favorite new features of JS is the humble AbortController, and its AbortSignal. It enables some new development patterns, which I’ll cover below, but first: the canonical demo.
It’s to use AbortController to provide a fetch() you can abort early:
It then continues with a series of nice use cases.
Via [Wayback/Archive] Roderick Gadellaa on Twitter: “Late to the party here (was published in June last yr) but great read if you (like me) missed it”.
