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.

A very important report from September 2025 for users of 18650 lithium-ion battery cells: [Wayback/Archive] The Lumafield Battery Quality Report.

Summary:

… beneath the surface, a hidden world of quality control issues and dangerous counterfeits puts consumers and manufacturers at risk.

Henriëtte Klijnstra got a new bank card in the name of “HENRI TTE KLIJNSTRA”, a Mojibake so bad that [Wayback/Archive] ftfy – fix unicode that’s broken in various ways cannot fix it.

[Wayback/Archive] Henriëtte Klijnstra on Twitter: “Ik moet dit nog checken bij founder @JornReuvers, maar misschien is dit toch wel het topstuk tot nu toe in de geschiedenis van #givetremasachance Congrats voor @Openbank en @bancosantander voor dit kunststukje op m’n nieuwe pinpas”.

A while ago Jason Scott put all these 400+ books on the Internet Archive:

We offer a competitive salary. Oh, I have amazing skills.

MacOS: change brightness of external monitor (via DuckDuckGo)

Posted by jpluimers on 2026/06/04

Seems this is not an easily accessible built-in feature of MacOS: [Wayback/Archive] macos change brightness of external monitor at DuckDuckGo

Basically there seem to be two apps that are most popular:

  • Lunar
  • MonitorControl

Lunar is free, but has a fee for some features. MonitorControl is free derived from Lunar, but has less features than the paid Lunar license has and is less often updated.

Both have been developed in Swift and are on GitHub:

Show HN: Live-updating version of the ‘What a week, huh?’ meme | Hacker News

[Wayback/Archive] Show HN: Live-updating version of the ‘What a week, huh?’ meme | Hacker News

As a fun evening project, I made a live-updating version of the ‘What a week, huh?’ meme (based on a panel from The Adventures of Tintin comics [1]).

There’s a page for every timeframe:

Current time is determined by a Cloudflare Worker using the request IP (not logged or stored). No JavaScript is sent to the browser.

It was easy to edit the HTML to change the message and CSS for the text dimensions, see the image on the right.

MacOS users will likely recognise the font as it is the Marker Felt font which is included by default on MacOS.

And it would be cool to alter the speech bubbles to be more like the ones Hergé used, see this comment:

Osmo-fl2k – osmo-fl2k – Open Source Mobile Communications

Posted by jpluimers on 2026/06/03

Interesting, but be aware that using it outside a shielded environment likekly is illegal: [Wayback/Archive] Osmo-fl2k – osmo-fl2k – Open Source Mobile Communications

  • osmo-fl2k allows to use USB 3.0 to VGA adapters based on the Fresco Logic FL2000 chip, which are available for around $5, as general purpose DACs and SDR transmitter generating a continuous stream of samples by avoiding the HSYNC and VSYNC blanking intervals.

  • Operating a transmitter with the unfiltered FL2000 DAC output attached to an antenna outside a RF shielding chamber is dangerous. Don’t do it!
