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.

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."

> left and right, but with opposite phase

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:

L = 0.707 * (M+S), R = 0.707 * (M-S)

which is where "opposite phase" comes into play.

Please re-read the historical record, key-words: "Stove pipe." The institutional read (NEI) was no WMD. International inspectors said no WMD. Cheney wanted another answer and got what he wanted by subverting the institutions.

I love a good used book store. Two years ago I found this:

Storm, Herbert F, Magnetic Amplifiers, Wiley, 1955. LOC# 55-6432

Covers applications and theory, contains All The Math.

We had colleagues, photocopiers and telephones. A good lab had a large library and many shelf-feet of schematics. Search was difficult, sure, but copy pasta was just as fundamental to a young engineer then as it is now. The consequences for bad judgement were however a bit smokier (is that why my memories are hazy?)

There is a book, "Challenger: A Major Malfunction: A True Story of Politics, Greed, and the Wrong Stuff". There is also Feynman's report. Recommended reading!

Yes, for decades I have practiced and preached this. Even more motivating: take a job that requires a deliverable in your language of choice. Swim or be eaten by sharks!

DCP developer here. DCP track files are MXF. SMPTE ST 377:2004 (MXF) predates SMPTE ST 429-3:2007 (DCP Sound and Picture.) ST 377 is a normative reference of ST 429-3. There is no zip file. There is no central registration for encryption. Each Media Block has a 2k RSA key (usually generated inside the FIPS 140 boundary), and each content distributor has a collection of the respective X.509 certificates.
