I Built a Commodore 64 Laptop That Never Existed (PI + EMULATION) – The Portable 64 Concept Design – YouTube

Posted by jpluimers on 2026/05/06

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.

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.

bash script for $* loop accept command line with spaces in wildcard file names at DuckDuckGo

Posted by jpluimers on 2026/05/05

Back when I wanted a more universal solution [Wayback/Archive] bash script for $* loop accept command line with spaces in wildcard file names at DuckDuckGo I got into a mess of tips that either did not work at all, or were very convoluted.

As back then I only needed a one-time solution, I just listed the filenames with ls into a text file, did some sed and editing steps, then had each file execute in a separate step. Low tech, non-repeatable when new files appeared, but good enough.

In case I want to go for a more universal solution, below are some links to investigate further. Will likely take me hours, so most of the time this is not worth it. Maybe the subshell plus $IFS (Input Field Separators) is a good start, though it gives me a feeling that in the future it will break something else that was expecting a default $IFS value, as is using while read loop. Both types of solutions feel too convoluted. Same for the array solution below.

I might have just been spoiled with PowerShell piping objects instead of strings having made life so much easier.

Arjen Lentz Crystal Ball Vulnerability Prediction: A Wizard’s Guide to Foreseeing the Unseen: NLUUG voorjaarsconferentie, 7 mei 2026, Arjen Lentz over de echte root cause van veel CVE’s en hoe die te fixen

Posted by jpluimers on 2026/05/04

Ook vandaag even een herinnering aan de NLUUG voorjaarsconferentie 2026 van (komende) donderdag 7 2026 mei in het Van der Valk Hotel Utrecht¹.

Deze keer omdat een goede vriend van me daar spreekt. Arjen Lentz heeft het over A Wizard’s Guide to Foreseeing the Unseen.

Dat klinkt misschien vaag, het concrete resultaat is dat je met analyse van CVE’s veel te weten komt over hun echte root cause. Die blijkt verrassend voorspelbaar, is fixbaar, en kennis daarover is niet alleen nuttig voor adversaries. Het kan jou namelijk helpen bij de development en selectie van wat je zelf gebruikt.

Het volledige programma staat hieronder², eerst de aankondiging van [Wayback/Archive] L⭕️rd Quux RCX CCX: “Over een week is het zover! De enige NLUUG conferentie van 2026. …” – Mastodon

Ventoy: an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files.

Posted by jpluimers on 2026/05/01

When undergoing cancer treatment, I missed the launch of [Wayback/Archive] Ventoy:

Ventoy is an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files.
With ventoy, you don’t need to format the disk over and over, you just need to copy the ISO/WIM/IMG/VHD(x)/EFI files to the USB drive and boot them directly.
You can copy many files at a time and ventoy will give you a boot menu to select them.

Source code: [Wayback/Archive] GitHub – ventoy/Ventoy: A new bootable USB solution. (2020 new, that is, but for me it was actually new)

Wikipedia: Ventoy – Wikipedia

Note there is also [Wayback/Archive] iVentoy, which is a PXE boot tool, but only partially open source and if used commercially you need a license. See:

Some Twitter internals after I found GitHub – offish/twitter-broadcast-downloader: Download Twitter broadcasts/lives

Posted by jpluimers on 2026/04/30

Found this while trying to find the source from which I constructed this Bookmarklet which from a Tweet URL returns the JSON metadata which has all the links to media (like images and videos) as it failed for broadcasts:

javascript:{ tweetID = document.location.href.split('/').filter(e => e).slice(-1); url = new URL(`https://cdn.syndication.twimg.com/tweet-result?id=${tweetID}&token=!`); open(url); }

I could not find that back, but did find [Wayback/Archive] GitHub – offish/twitter-broadcast-downloader: Download Twitter broadcasts/lives via these query steps:
