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.

One Winder to Rule Them All – Bambu Filament? No Problem! – YouTube

Posted by jpluimers on 2026/07/09

Interesting, I am going to try to make one with help of Viskip: [Wayback/Archive] Post by @viskip.bsky.social — Bluesky

Wil je deze ook? Ik heb nog een op maat gemaakte as waar ik niets mee doe.

This is the device: [Wayback/Archive] One Winder to Rule Them All – Bambu Filament? No Problem! – YouTube

Maybe at the time of publication, I already made it.

The cool thing: it also winds other things like electromagnetic coils – you can see that towards the end of the video.

A bit of perl trickery (or why you don’t should just execute any code you find on-line)

Posted by jpluimers on 2026/07/09

[Wayback/Archive] A bit of perl trickery shows a great example why you should only code you understand.

It explains the innards of a classic trap luring people into execute some obfuscated code, in this case Perl based.

Which makes it yet another testament to not blindly download and execute stuff from the internet.

So be aware when you see obfuscated scripts and things luring you into:

Be even more alert when these require elevated access (like running under sudo).

Via: [Wayback/Archive] Leo Bicknell on Twitter: “@jpluimers @IanColdwater Executes “rm -rf /”. This is ancient Perl monks way of teaching people not to run programs they don’t understand as root. … But hey, these days people “curl -o – url | bash”. It’s surprising that isn’t exploited more.”

Which was response to me asking what the below code did that was fully misunderstood by ChatGPT (which is Large Language Model based on a large corpus of natural language, not a small corpus of evil red-team programming language code snippets) to a series of Tweets by Ian Coldwater.

Paul Schoe: “… Many people confuse the benefits of automation with a perceived need for AI or LLMs …” – Mastodon

Posted by jpluimers on 2026/07/08

The very to the point post [Wayback/Archive] Paul Schoe: “@dentangle You are totally c…” – Mastodon

You are totally correct.

Many people confuse the benefits of automation with a perceived need for AI or LLMs.

They don’t want ‘intelligence’ to do things for them. They want to implement a set of rules that they themselves define, to be done automatically instead of having to do it themselves. That is automation.

was a response to a more precise post [Wayback/Archive] Brett Sheffield (he/him): “I see people recommending LLMs repetitive tasks …” – chaos.social

microsoft/pyright: Static Type Checker for Python

Posted by jpluimers on 2026/07/07

I will likely need this one day: [Wayback/Archive] microsoft/pyright: Static Type Checker for Python

Via:

  1. [Wayback/Archive] Julia Evans on Twitter: “I wish there was something like pyright for Javascript — I love how pyright will tell me about type errors even if I don’t add *any* type annotations in my code at all github.com/microsoft/pyright (I assume you can’t make pyright-for-JS because Typescript is a different language)”
  2. [Wayback/Archive] Julia Evans on Twitter: “Also I think the reason pyright works so well even if I don’t add type annotations is that a lot of the Python library code I’m depending on actually does have type annotations, so it can use those”
