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 »

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.

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

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.:

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.

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.
More links from this trip down memory lane:

A few years back I tweeted [Wayback/Archive] Jeroen Wiert Pluimers @wiert@mastodon.social on Twitter: “@b0rk @jilles_com Acids vs bases.”

It was a kind of tongue-in-cheek reaction (with a way better picture below) to a very valuable post by b0rk (Julia Evans) on both Twitter and Mastodon [Wayback/Archive] Julia Evans on Twitter: “bases” / [Wayback/Archive] Julia Evans: “bases title: bases # we usually…” – Mastodon for two reasons:
- There are various interpretations of bases
- Octal is very important to educate as errors introduced by its support are hard to spot even if you do know about octal.
