mutool: all purpose tool for dealing with PDF files | mupdf Commands | Man Pages | ManKier

Posted by jpluimers on 2025/09/23

Sometimes I feel like having lived under a rock for ages despite trying to live the command-line life as much as possible.

Anyway: not that long ago I learned about [Wayback/Archive] mutool: all purpose tool for dealing with PDF files | mupdf Commands | Man Pages | ManKier

It is part of [Wayback/Archive] Package mupdf – man pages | ManKier which also has [Wayback/Archive] mupdf: MuPDF is a lightweight PDF viewer written in portable C | mupdf Commands | Man Pages | ManKier.

MuPDF – a kind of sibling to GhostScript – lives at [Wayback/Archive] MuPDF: The ultimate library for managing PDF documents.

The below query got me to [Wayback/Archive] mupdf/docs/man/mutool.1 at master · ccxvii/mupdf · GitHub in the “wrong” repository [Wayback/Archive] GitHub – ccxvii/mupdf: mirrored from git://git.ghostscript.com/mupdf.git

The actual repositories are at:

433 MHz is not dead! Using an ESP32 board with LoRa module to talk to 433 MHz sensors – CNX Software

Posted by jpluimers on 2025/09/23

This was a cool post: [Wayback/Archive] 433 MHz is not dead! Using an ESP32 board with LoRa module to talk to 433 MHz sensors – CNX Software

433MHz LoRa Transceiver-based ESP32 board work with regular 433 MHz sensors found on the market. This gives end users a simple off-the-shelf solution for receiving these signals without having to use a soldering iron and making a circuit.

This opens many doors regarding 433 MHz sensor readings with one device, including weather stations, doors, PIR, TPMS, temperature, and BBQ sensors.
Recommended reading!

Dell 3060/5060/7060 Micro RP-SMA dual-band WiFi antenna parts Y9MPH and 3TJ9N

Posted by jpluimers on 2025/09/22

Two kinds of RP-SMA dual-band WiFi antenna parts having :

  • Y9MPH is an omnidirectional dipole stick antenna which most use
  • 3TJ9N is a semidirectional patch/panel antenna on a wire which few people use but can be useful when you want to put the antenna into a place having better signal reception

Both are also supposed to work for Dell OptiPlex Micro models 3020/3040/3050/5020/5040/5050/7020/7040/7050 (as 5030/7030 models were never released and 3030/9030 only released as a different all-in-one PC form factor): basically the end of the Micro form factors in Dell OptiPlex Series 4 and start of Dell OptiPlex Series 5.

Links (some also containing part numbers for other related components like internal wiring and M.2 Wi-Fi cards):

Drie observaties over de tech/geld maatschappij waarin we leven

Posted by jpluimers on 2025/09/19

Observaties waarin de maatschappij als geheel vast aan het lopen is:

  1. [WaybackSave/Archive] De ware aard van big tech: ‘We zijn heel hard op weg om terug naar de middeleeuwen te gaan’ | de Volkskrant
  2. [Wayback/Archive] Kelly: “Before you judged someone for being disabled, unhoused or struggling …remember that most people are one accident, medical emergency or stroke of bad luck away from same fate. Judge the capitalistic system that treats us as cogs. Judge those who value economic contribution above everything else.” — Bluesky
  3. [Wayback/Wayback] Jeroen Wiert Pluimers: “This, plus that diversity is a blessing, not the burden that uniformity is.” — Bluesky

De eerste is via [Wayback/ArchivePost by @huibmodderkolk.bsky.social — Bluesky

‘De samenleving zou weleens wat kritischer tegenover het verhaal van Silicon Valley mogen staan. Technologie is niet zomaar een instrument, maar verandert ook hoe mensen denken’

I why I always use light mode: it’s easier on the eyes, as explained by Kristian Kohntopp

Posted by jpluimers on 2025/09/19

In a German thread, Kristian Köhntopp perfectly explained why I too always use light mode, so I put the English translations here:

  1. Dark mode is a strain on the eyes and useless.
  2. Specific: In darkness (and in dark mode) your pupils widen, the diaphragm opens. This reduces the depth of field and the eye muscles have to do more work and precision when focusing.
  3. Conversely, with light and a bright background you have a smaller pupil, a small aperture and more depth of field. This means that everything is automatically sharp, even if the eye has not readjusted.

The German thread:

August 2025 — AI False Claim Monitor – NewsGuard: AI False Information Rate Nearly Doubles in One Year

Posted by jpluimers on 2025/09/18

NewsGuard August 2025 One Year Progress Report: Percentage of Responses Containing False Information

NewsGuard August 2025 One Year Progress Report: Percentage of Responses Containing False Information

This is what I have been warning for since 2020: AI LLM will end up in a downward quality spiral.

My reasoning back then, and still now is that they:

  • cannot distinguish LLM generated training data from human data making the LLM worse over time
  • don’t perform human curation thereby not solving the worsening

I’m not surprised by the [Wayback/Archive] August 2025 — AI False Claim Monitor – NewsGuard summary:
