GitHub – bbbradsmith/flompy: DOS floppy disk dumper
Posted by jpluimers on 2022/04/26
Need one day when archiving old floppies: [WayBack] GitHub – bbbradsmith/flompy: DOS floppy disk dumper
Via: [WayBack] Brad Smith on Twitter: “So I wrote a floppy disk dumper program for DOS. I dunno if this is really a very useful thing, but it’s open-source at least! 💾⚡🖥 “
Full thread at [WayBack] Thread by @bbbradsmith: “Hrm… why doesn’t the floppy controller status register have its non-DMA bit set, even though I’ve used a specify command to set it… and […]”:

Jeff Geerling on Twitter: “I plug computers into my computers…”
Posted by jpluimers on 2022/04/20
Hopefully the picture below is the board of a PCIe KVM board based on a Raspberry Pi Compute Module 4 supporting Power over Ethernet (PoE).
At least it seems to looking at the thread started by [Wayback/Archive] Jeff Geerling on Twitter: “I plug computers into my computers… “:
- [Wayback/Archive] eComet on Twitter: “@geerlingguy It will work as KVM or remote console for main computer?”
- [Wayback/Archive] Crenn on Twitter: “@geerlingguy We’re getting close to my wish!”
- [Wayback/Archive] Crenn on Twitter: “Random concept I thought of while debugging my server today. Have a PCI-E 1x card hosting an FPGA to create a basic graphics card implementation outputting to CSI (aka PiKVM) going to a @Raspberry_Pi 4 compute module; creating a self contained IPMI solution for headless servers.”
It would also very much match the below issue that Jeff raised:

Kris on Twitter is a bit radical against shell scripts. Learn why.
Posted by jpluimers on 2022/04/13
I say to people: only use shell interactively, don’t write scripts. Never. Not one.
But Kris, they ask, why so radical?
Because of this:
is the literal English Google Translation of the German text
Ich sage den Leuten: benutzt Shell nur interaktiv, schreibt keine Scripte. Nie. Nicht eines.
Aber Kris, fragen sie, wieso so Radikal?
Deswegen:
then links to [Wayback/Archive] Jan Schaumann on Twitter: “TIL zgrep(1) is a shell script. BSD basically does “zcat | grep”, but GNU does “gzip -dc | sed”. How did I learn that? The fun way! CVE-2022-1271, arbitrary-file-write and code execution vulnerability in GNU zgrep / gzip. …”:

When some virtual machines cannot run VMware Tools: Graceful shutdown of an ESXi 5.1 host and guest VMs (free edition) using the shell/command line/scripting (UPS friendly)
Posted by jpluimers on 2022/04/12
An interesting set of scripts from [Wayback/Archive.is] No Joke IT: Graceful shutdown of an ESXi 5.1 host and guest VMs (free edition) using the shell/command line/scripting (UPS friendly).
If all ESXi virtual machines support running of VMware Tools, then the solution is a plain /sbin/shutdown.sh && /sbin/poweroff (see [Wayback/Archive.is] No Joke IT: Shut down ESXi 5.1 guest VMs and the host (free edition) via SSH – the easy way!).
Code is in the repository at [Wayback/Archive.is] sixdimensionalarray/esxidown: A shell script to shutdown VMware ESXi host servers, with these two main files:
- [Wayback/Archive.is] esxidown/async.sh at master · sixdimensionalarray/esxidown
#!/bin/sh # Runs a shell command asynchronously. if [ "$1" != "" ]; then nohup sh $1 > /dev/null 2>&1 & fi - [Wayback/Archive.is] esxidown/esxidown.sh at master · sixdimensionalarray/esxidown with this interesting code fragment right before the script finishes:
# exit maintenance mode immediately before server has a chance to shutdown/power off # NOTE: it is possible for this to fail, leaving the server in maintenance mode on reboot! echo "Exiting maintenance mode..." if [ $TEST -eq 0 ]; then esxcli system maintenanceMode set -e false -t 0 fi
Note: the No Joke IT web-site has vanished, so only the [Wayback] and [Archive.is] links of it still work. The github code was still there at the time of writing.

Prevent link rot before the public condemns you
Posted by jpluimers on 2022/04/05
I’ve written about link rot quite a few times (it even has a category on my blog).
Preventing it is important, as it improves user experience.
For most users this is an unconscious thing when it works and becomes consciously annoying when it fails.
Some user groups are vocal enough to force you to fix link rot after the fact, causing brand reputation damage.
One good example was last year: [Wayback] Users condemn Microsoft for removing KB IDs from some bug documentation | Computerworld.

Every site should present this as a captcha today.

Bookmarklet to force WordPress classic-editor
Posted by jpluimers on 2022/03/29
A while ago, WordPress.com heavily started to de-emphasise the Classic Editor in order to boost the Gutenberg editor which is bloaty (in both browser DOM usage (heavily slowing down editing) and content (lots of meta tags that are added to blog source) and is missing essential features (especially nesting of blocks often breaks things).
With 7000+ blog posts in the Classic Editor format (a few in still supported markdown format: that experiment failed horribly!) that still require editing (especially because of link rot)
So here is the Bookmarklet code to switch back an editing URL that you can use for as long as the Classic Editor is there:
javascript:location.href=document.location.href+'&classic-editor';
Yup, it is that simple: it appends &classic-editor to the URL.

WordPress undocumented Classic-Editor shortcut “Shift-Ctrl-F” that goes full screen
Posted by jpluimers on 2022/03/28
Suddenly, a while ago, because of a stuck modifier key I suddenly had the WordPress classic editor running in full screen without any indication to go back, nor an opportunity to save the content.
It wasn’t the usual “Shift-Alt-W” [Wayback] Distraction Free Writing – Make WordPress Support (which still allows you to hover over the sidebars to make them visible, and has a visual indication of the mode).
After lot’s of trying, I figured out the toggle “Shift-Ctrl-F” toggles between normal and full screen mode. It seems unavailable in the new editor, so that might be a reason ([Wayback] Keyboard Shortcuts | WordPress.org)
The shortcut is odd too, as in most tooling “Ctrl-F” modifications like “Shift-Ctrl-F” have something to do with find or replace operations.
It was quite tough finding any reference to this shortcut, as my initial search revealed none: [Wayback] “WordPress” “Shift-Ctrl-F” full screen – Google Search.
Later I reversed the modifiers in [Wayback] “WordPress” “Ctrl-Shift-F” full screen – Google Search and found [Wayback] How to disable non-system hotkeys on Windows – gHacks Tech News
Simple Disable Key is a free software program for Microsoft Windows devices that enables you to block non-system hotkeys.
…
Not all hotkeys are useful however. When I work on a WordPress site for instance, I sometimes press the shortcut Ctrl-Shift-F by accident. This switches the editor to full screen view which I never use.
First time I invoked the full screen editor I had to look up the shortcut as I could not reproduce it.
