Often connections are TCP based, but sometimes UDP is all you have to test with, so I was quite surprised that testing that was quite forward. The solutions by [Wayback/Archive] How to Do a UDP Ping in Linux works on any platform where you can have nmap or netcat on installed (which by now is almost all platforms including Windows):

MacOS (at least 2023 and younger): solution for (TrueType) fonts added through MacOS built-in Font Book not showing up in Pages or Preview
Posted by jpluimers on 2026/01/05
It took me a few queries to find the correct online solution for this problem: after adding a TrueType (and it’s extension: OpenType) font using the built-in MacOS Font Book, they do not show up in Pages or Preview, not even after validating the fonts in Font Book.
Solutions:
- reboot (found this out myself)
- killing the fontd font daemon from the Activity Monitor
- restart font daemon (found out via the link below)
launchctl kickstart -k gui/`id -u`/com.apple.xtyped
The last one does not work on my Apple Silicon machine, the first two work fine.
For Preview, you have to Force Quit it then start it (so it re-opens all the previous files) to take effect.
I needed this, because I
- very much like the Lucida font family and especially use Lucida Console a lot when filling out forms.
- need the KIX-code font often (it is as barcode font derived from RM4SCC)
- bought [Wayback/Archive] Brush Tip Terrence Font | dafont.com for stationery a long time ago and still use it
- occasionally use [Wayback/Archive] macfonts/Macintosh OS X/mac-icon-standard.ttf at master · JohnDDuncanIII/macfonts · GitHub (which I saved from the 30th Mac anniversary in 2014 – see links below) when documenting Classic Macintosh stuff
- often use the Myriad typeface that Apple supplied with the 30th anniversary of the Macintosh (see links below)

n modern versions of Mac OS, like macOS Mojave, Catalina, Sierra, OS X El Capitan, and Yosemite, you can shorten the syntax considerably as so:defaults read /Library/Preferences/SystemConfiguration/com.apple.airport.preferences |grep SSIDStringIn prior versions of Mac OS X, you can opt for the same as the above command, or use the lengthier string below with heavy regex:

MacOS: open file in other monitor
Posted by jpluimers on 2025/11/24
When I have an external monitor connected to my 2015 era Retina MacBook Pro machines, I wanted some apps to appear on the laptop screen and others on the external one.
That was harder than I hoped for as no single solution works in all cases.
What I do now is to make sure the icon bar is on the monitor where I want applications to open. Not perfect, but works for most cases.
Here are some links that helped me:

When Spotlight fails to find some files: mdutil revisited
Posted by jpluimers on 2025/11/07
On my M1 MacBook, somehow Spotlight started to fail returning some indexed files (especially recently added ones would not show up or it would take a very long while for some of them to show up).
So I revisited mdutil and related commands while writing a comment on the YouTube movie [Wayback/Archive] How To Rebuild the Spotlight Index on Your Mac – YouTube which since then vanished, but luckily I saved it and here I amended it with formatting:

command line – Why does a cURL request return a percent sign (%) with every request in ZSH? – Stack Overflow
Posted by jpluimers on 2025/07/31
I try to stay on the default shells of environments as much as possible, especially as that makes life easier when needing to work on an non-customised system.
Apple switched back from an ancient latest GPLv2 version 3.2 of bash (they regard newer GPLv3 as toxic to their revenue stream¹), introduced MIT-license based zsh and introduced a bash nag screen a few years ago forcing users to switch. Suppressing that message reliably is trickier than you might think².
After so many years of bash, I still stumble over things that zsh does differently: [Wayback/Archive] command line – Why does a cURL request return a percent sign (%) with every request in ZSH? – Stack Overflow (thanks [Wayback/Archive] Travis and [Wayback/Archive] zaTricky) is a “feature” with a simple workaround for cURL:
This is a zsh feature that prints a percent-and-newline after a command completes if that command does not already include a newline at the end of its output. If zsh did not do this, you would either not ever notice the fact that the command didn’t print a newline – or you’d see zsh’s command prompt not start on the margin and think it was a bug in zsh.

$ curl http://api.macvendors.com/0015c7 Cisco Systems, Inc% $ curl -w '\n' http://api.macvendors.com/0015c7 Cisco Systems, Inc…
Since the above example now writes a redirect messages (good bye HTTP, welcome HTTPS), and I very much dislike short command-line parameters, here is version with the long form of the [Wayback/Archive] curl -w or --write-out parameter :
