I feel old, because I vividly remember the PCX (1985) graphics file format: it was the defacto standard under DOS.
TIFF (1986) was slightly younger, and came from the scanner background resulting in very large files though unlike PCX (which had lossless compression), TIFF supported both lossless and lossy compression.
On Windows and OS/2, you had BMP (1985, lossless initially only black and white).
All three suffered from the same problems: different implementations causing all sorts of compatibility problems
Those were the reason for the implementation of newer file formats for graphics like JPG (1992, lossy) and PNG (1996, lossless).
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):
Everytime when installing a pfSenserouter from scratch, I seem to re-learn a few of the below quirks. So it was finally time to document them (:
Quite a few of my pfSense configurations are just doing routing between various networks, should not provide DHCP leases and do not always need or have a WAN connected (i.e. they are LAN-only).
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)
I got 3 of them (2 are variations of the same model) and their quality/price ratio is great, even with the prices that risen during the 2020-onwards global chip shortage.
The final version of HP-UX has, as of 3 days ago, officially hit “obsolescence” and is no longer supported.
While most versions of HP-UX had hit “end of life” some years back, version 11i v3 (specifically for Itanium servers) was still supported. At least… until the clock struck midnight on New Year’s Eve.
HP-UX joins the likes of IRIX (support ended in 2013).
Luckily there are still a few classic style UNIX systems in production… but the list is growing smaller with each passing year.
