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.

Some notes on PCIe based KVM over IP and splitting video (as modern KVM over IP do not seem to do passthrough) for remote out-of-band management

Posted by jpluimers on 2026/03/13

The notes are based on the NanoKVM PCIe as that is what I wanted to set-up on a Windows 11 compatible PC that could be remotely managed for someone not savvy enough to do that themselves. They had an old Supermicro based PC with IPMI which kind of does IPKVM when using the embedded video hardware, but back when I wrote this early 2025 – the year Windows 10 would become end-of-life – it was:

  • a nightmare to figure out which Supermicro mainboards were Windows 11 compatible
  • remote IPMI tooling ¹ was a pain to get working (the most important one is IPMIView which requires Java and even with Java installed would have issues connecting to various generations of IPMI)
  • newer KVM tooling has way better
    • user experience than classic ones like IPMI and iDRAC
    • features like for instance WireGuard support which makes for way less network configuration
    • open source software (for at least NanoKVM I mention here, but also for Pi-KVM which has the drawback of also requiring a Raspberry Pi)

Since none of the modern remote KVM hardware tooling seems to be able to do passthrough video, the solution I researched for was to split the outgoing video signal (either Displayport or HDMI), then optionally convert Displayport to HDMI and finally route that HDMI into the remote KVM hardware.

Delphi documentation: GetIt Local files – Google Docs

Posted by jpluimers on 2026/03/11

This [Wayback/Archive] GetIt Local files – Google Docs is so much better than the [WayBack/Archive] DocWiki documentation for at least these reasons:

  • it is one coherent document
  • it is complete and does not cut away parts of the source code examples (especially the JSON in the DocWiki is bad)

I wish it had been a Markdown or reStructuredText document as that is far more version control friendly.

Hopefully it will stay on-line longer than [Archive] drive.google.com/file/d/1Pt0YOMfS1eJK7e-NyLrZ5dNOj6UlqN1U/view| or the DocWiki documentation of prior Delphi versions. For more on that, read this blog post: The Delphi documentation site docwiki.embarcadero.com has been down/up oscillating for 4 days is now down for almost a day..

If you are curious to the DocWiki documentation on the GetIt Local files, then read these:

Unix/MacOS: “rm: illegal option — b” or how to remove files that have their name starting with a minus sign.

Posted by jpluimers on 2026/03/11

I had to remove all text files including a -bar.txt from the current directory using bash, so I automatically typed rm *txt resulting in this nice error:

rm: illegal option -- b
usage: rm [-f | -i] [-dPRrvW] file ...
       unlink file

When there was just a file named -foo.txt in the directory, the error became more interesting:

rm: illegal option -- o
usage: rm [-f | -i] [-dPRrvW] file ...
       unlink file

Then it struck me: rm is one of those old tools where you can smack all options together. Read the rest of this entry »

Do This Before You Solder Anything – YouTube

Posted by jpluimers on 2026/03/10

Soldering steps and common problems - Adafruit

Soldering steps and common problems – Adafruit

These are nice references when you start to learn soldering:

The right part of the image from Adafruit is an almost 10 year old one that is heavily copied without reference. With reference, it is at¹

Adafruit also has this great link: [Wayback/Archive] Common Soldering Problems | Adafruit Guide To Excellent Soldering | Adafruit Learning System

The video:

  • Clean with isopropyl alcohol
    • Before soldering
    • After soldering

    Do not use (in the USA popular) rubbing alcohol, as that is only 70% (and 30% water) alcohol by volume: use at least 90%

    • Use a dispenser for alcohol to dose tiny bits
    • Use a non-woven tissue (large areas) or swab (small areas) for cleaning

MacOS and Windows: sorting – Simple to enter Unicode character that would sort after Z in most cases? – Stack Overflow

Posted by jpluimers on 2026/03/10

TL;DR: There is no simple character that works on both MacOS and Windows.

[Wayback/Archive] sorting – Simple to enter Unicode character that would sort after Z in most cases? – Stack Overflow (thanks [Wayback/Archive] sorin and [Wayback/Archive] degenerate):

A

On Windows, none of these options work because they all sort before A.

A solution I ended up using is an Arabic character:

ٴ This folder comes after z in windows

Source

According to [Wayback/Archive] What Unicode character is this ?, the above mentioned character is U+0674 : ARABIC LETTER HIGH HAMZA.

Note that on Windows the ٴ character displays at the start of the filename, but on MacOS in Finder it ends up behind the extension (as Arabic script is right-to-left) and is very hard to remove. On the MacOS Terminal it ends up on the left and is easy to modify.

Solving OKI Errors while printing “544: Invalid Y C”, “545: Invalid M C”, “546: Invalid C C”, “547: Invalid K C”, or “544:Y Invalid C”, “545: M Invalid C”, “546: C Invalid C”, “547: K Invalid C”

Posted by jpluimers on 2026/03/09

If any of the below OKI error codes occur during printing then first re-seat (unlock, then lock) the corresponding toner cartridge.

When the error reoccurs, then wear a mask (toner spills can be dangerous to your lungs), then: unlock the toner cartridge, remove it, vacuum away any of the toner spill in the printer and on the cartridge, reinsert it and lock it.

The cause is a mechanical issue that happens both when only using original OKI toner cartridges and OEM or third party ones: wear of the parts over time will spill more and more toner causing the locked cartridge detection to cause a faulty result due to excessive spilled toner build-up.

For me this mostly happens on the colour cartridges and far less often on the black cartridge.

Error code list for the message at [Wayback/Archive] Troubleshooting | OKI “Check Toner Cartridge. Improper Lock Lever Position. Error: 544, 545, 546, 547”:

  • 544: Yellow (abbreviated as Y)
  • 545: Magenta (abbreviated as M)
  • 546: Cyan (abbreviated as C)
  • 547: Black (abbreviated as K, but sometimes as B)

On the above page self the solution lists as
