I also had problems with MathML verbosity, and the culprit is the markup for the individual character classes (mi, mn, mo, ms.) I wrote a little filter that pulls apart character sequences and applies the respective character markup tags using a lookup table, so I can write MathML without using character markup. If any character markup is already present then it is skipped, so the automatic behavior can be bypassed by explicitly tagging characters and symbols as needed. This drastically reduces the character markup and makes it quite readable, even to my dyslexic eyes. As a bonus I'm not tied to some other tool that I have to game from time to time to get a particular MathML expression, I can say exactly what I want. BoBW.
40-some years ago in L.A. some guys discovered that a Burger King drive-up kiosk was tied to the restaurant with an RF link. It was a simple matter to determine the frequency and modulation mode and program a hand-held transceiver to use the same link. They set up in an adjacent parking lot with a video camera and set about pranking the customers that drove up. The resulting video, titled "Attack on a Burger King" (these guys were video engineers,) was copied all around town by the same studio rats that shared session outtakes, Red's Tube Bar, etc. It ends with an employee coming out, jogging toward the kiosk, while the hackers convince the customer to flee the angry man approaching them. Dunno if it ever made it to streaming.
Ah, yes, A lot of old fast food drive-thru headsets were in VHF business band (and similar). The Phone Losers of America were well known for their exploits to that regard.
I'm surprised to see no references to space applications. Back when I was using Kermit on CP/M I had an acquaintance who hacked Kermit for satellite coms at TRW in El Segundo. Long live W6TRW!
Really? Was Perl 5 deprecated with prejudice across ecosystems, forcing projects to work with a janky, still-evolving replacement well ahead of production-grade stability? Because the boot marks in my ass from the forced march to Py3 are still bleeding.
Null Island is where you will find Bias Beach, the "/dev/null" of magnetic tape recording. As in, "where is the guide vocal?" "I sent it to Bias Beach to make room for the cowbell."
The classic mid-side mic technique uses two capsules. The first (middle) is a cardioid or omnidirectionsl facing the subject, the latter (side) is a figure-8 turned 90 degrees. The capsules should be as close to each other as possible to avoid low-frequency phase errors. The signals are converted to L+R via a simple Mid/Side network:
