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”

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

Installing Poppler on Windows via Chocolatey, which includes pdfimages for lossless extraction of images from PDF files

Posted by jpluimers on 2026/03/09

At the time of writing there was an almost 3 year old [Wayback/Archive] Chocolatey Software | Poppler 0.89.0 version so I filed the issue [Wayback/Archive] poppler 23.03 has been out for a few weeks, can you please update the build? · Issue #88 · chtof/chocolatey-packages mentioning [Wayback/Archive] Pull requests · oschwartz10612/poppler-windows

Poppler 23.03.0

Since that did not get really solved, I finally found out that after installing scoop, then scoop install poppler did work and installed version 23.08.0 (which I documented in [Wayback/Archive] Poppler version out of date · Issue #75 · chtof/chocolatey-packages installs from the most recent [Wayback/Archive] Releases · oschwartz10612/poppler-windows).

A very different approach is to install Poppler inside Windows Subsystem for Linux (WSL) as explained in [Wayback/Archive] Poppler On Windows. Python, PDFs, and Window’s Subsytem for… | by Matthew Earl Miller | Towards Data Science.

I needed Poppler (or actually the Windows equivalent of poppler-utils) of two reasons:

  1. I wanted to experiment with pdftotext as it has these very compelling command-line switches.
  2. I needed to export images for which pdfimages is the poppler tool to go.

Solved: CPU Xeon E5-1620 v.4 does not allow Windows 11 upgrade – HP Support Community – 8645349

Posted by jpluimers on 2026/03/06

I might need this: [Wayback/Archive] Solved: CPU Xeon E5-1620 v.4 does not allow Windows 11 upgrade – HP Support Community – 8645349

You don’t download the ISO file to a USB stick.

You download it to your PC and use the free Rufus utility that I zipped up and attached in that discussion link I posted to transfer the ISO file to a DVD so that it is bootable.

You have to use the version I attached 3.18 because the newer Rufus versions removed the W11 hardware check bypass hack.

Try it again in the morning when you are ‘bright eyed and bushy tailed’ as we say in the USA.:

HelgaDulfer on Twitter: “@zorgenzo Probeer form op te slaan en dan met Adobe Fill&Sign in vullen en ondertekenen; vervolgens kun je ingevulde exempl. mailen of weer opslaan” / Twitter

Posted by jpluimers on 2026/03/06

[Wayback/Archive] HelgaDulfer on Twitter: “@zorgenzo Probeer form op te slaan en dan met Adobe Fill&Sign in vullen en ondertekenen; vervolgens kun je ingevulde exempl. mailen of weer opslaan”

I took a quick look, but the mobile Fill & Sign apps on Android and iOS are even harder to use for filling out forms than using Acrobat Reader on PC or MacOS Preview.

UTF-8, Explained Simply – YouTube

Posted by jpluimers on 2026/03/04

Cool interesting video: [Wayback/Archive] UTF-8, Explained Simply – YouTube

It covers both history from the late 1800s Baudot Code (also known as ITA1) via 1930s ITA2 and 1950’s EBCDIC / FIELDATA ages through 7-bit ASCII in the 1970s  and incompatible UCS-2 (now UTF-16) of the 1990s to the current day and age of UTF-8 (which actually started out on a placemat in 1992).

Though mentioning 8-bit encoding, it skips details of extended ASCII encodings like ISO/IEC 8859 and Windows-1252.

It goes to quite some length on decoding UTF-8 and showing how forgiving the UTF-8 standard is. Yes, it is a self-synchronising code thanks to the venerable Ken Thompson.

Definitely worth watching as it also covers the Zero-width joiner which is not just important for combining Emoji, as it is used by many people nowadays, but got in fact implemented to support various scripts like Arabic script or any Indic script.

Oh, the placemat story: Read the rest of this entry »

Odido-router verzamelt analytics van je huishouden en stuurt het door naar AI toko lifemote

Posted by jpluimers on 2026/03/04

Dit is net zo nalatig als de Odildo hack waar alle klantgegevens mee op straat kwamen te liggen: [Wayback/Archive] Odido-router verzamelt analytics van je huishouden

Bevindingen in het kort

  • De Odido-router haalt bij een nieuwe WAN-verbinding een bash-script op over een onversleutelde HTTP-verbinding.
  • Je kan dit script manipuleren om een root shell op je router te krijgen.
  • Als je TLS-verkeer mitm’t zie je analytics-data over de lijn gaan; de scripters hebben TLS-validatie uitgezet (`curl -k`) dus je kan dit ‘versleutelde’ analytics-verkeer inzien.
  • Je router stuurt namen en MAC-adressen van devices in je huis door naar Lifemote. Verder deelt het ding de SSID’s en MAC-adressen van WiFi-netwerken in de buurt. En wat analytics-stats over je dataverbruik. Lifemote adverteert met “AI-Powered Home Wi-Fi Solutions for ISPs”. Het voelt wat vies dat zij AI’s gaan trainen met data uit mijn huishouden. Daar vind ik wat van.

dasm – macro assembler for 8-bit machines

Posted by jpluimers on 2026/03/04

Finding a reference to DASM while researching yesterday’s post @jpluimers on Twitter: “@b0rk @jilles_com Acids vs bases.”, it felt even more like a trip like memory lane as I had used it in the 1980s on Apple ][ and Apple //e after mainly using EDASM. Lisa and Merlin.

I am glad that it is still alive and kicking with home page at [Wayback/Archive] dasm – macro assembler for 8-bit machines and repository at [Wayback/Archive] dasm-assembler/dasm: Macro assembler with support for several 8-bit microprocessors.

Especially this history section on the home page rang a bell:

  • Matthew Dillon started dasm in 1987-1988.
  • Olaf “Rhialto” Seibert extended dasm in 1995.
  • Andrew “Dr.Boo” Davie maintained dasm in 2003-2008.
  • Peter Fröhlich maintained dasm in 2008-2015.
  • In 2019, the dasm source code and releases were moved to GitHub.

Decoding HTML encoded source to XML text

Posted by jpluimers on 2026/03/03

For Some links on getting the most recent defragmentation time of a Windows volume I needed to copy back and forth some XML code back and forth between my ARM MacBook Pro to a remote Windows machine accessing via the Microsoft Windows App (the app formerly known as Microsoft Remote Desktop for Mac).

The problem with that is the copying would lose line breaks, which for XML meaning is no problem, but for human understandability while editing the XML in the Event View query dialog was.

So I decided to go to the “Code” view in my Classic WordPress editor (did I ever tell you much I dislike – especially the accessibility of – the not so new but still haughty named Gutenberg editor?), copied the HTML encoded form and wanted to convert it to unencoded XML text.

Well, here I got to naming confusion land, on which I will talk further below, but first two of the potential solutions:
