That's pretty neat... But does it work with postscript files? Or maybe pdf? I also assume it only works for networked printers?
The Handbook doc linked in the article shows how you can do the same over USB.

#102Earlier quoted context omitted.
Rinse & repeat when every desktop environment brought their own audio daemons, then later PulseAudio and now PipeWire. I still roll my eyes and I don’t get surprised every couple of years when somebody releases a yet another Linux audio daemon. Maybe it’s some kind of Linux tradition. At least PipeWire is saner compared to PulseAudio.
> every couple of years when somebody releases a yet another Linux audio daemon. You seem to be stuck in, oh, maybe 2008. There hasn't been "yet another Linux audio daemon" in more than a decade. JACK came along in the early 2000's (I wrote it), and PulseAudio in 2004 or thereabouts. All that nonsense with esd, artsd etc. was over because the aughts were over.
artsd.... now that's a name I haven't heard in a long time!
Re: Bye CUPS: Printing with Netcat
#103While the article is correct, it omits most of the actual function of CUPS. Many printers are capable of accepting various types of documents directly over the network, with postscript, HP PCL, and PDF being commonly supported---and ASCII pretty much universally supported. The problem is that few printers support _all_ of these standards. Postscript, for example, is surprisingly complex to implement in practice, whic…
What about Page Layout / Color/Mono selection etc.,?

Since I switched to pipewire, my audio is crackling every time the cpu is loaded (a ryzen 7...) not even jack was struggling with that on this machine
Double check that you're running PipeWire with rtkit (this is the default with PulseAudio, AFAIK it is not the default yet on PipeWire).
It is really important to run a sound daemon with realtime privileges. This is the only way to ensure no cracks.

#105Hah. I had a similar moment of enlightenment with FreeBSD when somebody explained that you can just cat a wav file into /dev/audio (or /dev/dsp? forget the exact name). And that you can produce white noise by catting /dev/random to the same destination. With no barrier to the sound card like that, I was free to experiment with programming dfferent noise algorithms and figuring out how digital audio works. I eventuall…
You used to be able to do that on Linux when its sound system was OSS ("Open Sound System", not "Open Source Software"), the same as FreeBSD uses today (I believe Linux still has an OSS compat layer). A long time ago the project lead was employed by a company to write support for some newer sound hardware, and decided to make those changes proprietary. The Linux folks decided to do something completely different, and we got ALSA, while some BSD folks decided to fork the last fully open source version of OSS and continue developing it.
The irony, of course, is that the proprietary version of OSS failed, and it ended up going open source again.

#106Question: is there an equivalent for printing over USB?

Yeah I did this at work recently with netcat. Our file sharing "solution" wasn't going to work so I just thought to try it for the hell of it.
I also setup a horrible video chat in bash using just vlc and netcat. Audio works better like this
Re: Bye CUPS: Printing with Netcat
#108I immediately tried it...
Aaand this is how I made my printer spit out dozens of garbage pages with just one to two lines of gibberish on each (the PDF source code, admirably giving up the page at each occurrence of the corresponding char)...

When I was first learning Linux many years ago a friend and I got intoxicated and catted /dev/hda into /dev/dsp. It was all basically static with sometimes very structured patterns that we would try to guess as to what filetype was producing them. He had download and forgotten about a long uncompressed audio recording of a piano performance on his drive that suddenly started breaking through the static in chunks of v…
mplayer -demuxer rawaudio -rawaudio rate=48000 -format s16le -af volume=-20 /dev/sda
Warning, headphone users: may hurt your ears. Trust me on the volume lowering.
With 16 bit samples and (default) two channels, you can recognizeably hear small integer values in your left ear. :)

#110I am printing from Ubuntoo for years withopt troubles, and don't even know is that CUPS or not. When installing Ubuntoo on new laptop I configure printing with help of internet search and forget.
Is Linux printing really such a problem?
