Playlists. In the world of audio, especially when it comes to critical listening and system evaluation, there is nothing more important than playlists. Those sonic references play a critical role in designing and evaluating an audio system’s performance. And when that system is in a $500,000 vehicle, it’s even more important to get it right.

I know, I know. Your plate is full. I won't recite the litany of things already on your mind. We've already recited that list plenty of times. Speaking for myself, I religiously devote a solid hour every night, usually between the hours of 3 am and 4 am, to reciting the list. Well, here's another thing for the list: SSL certificates. In particular, they seem to be expiring.

Well, it's official. I am throwing in the towel. My worldview has been shaken, stirred, crumbled, kneaded, blown apart, and reduced to its elemental atoms. Actually, at this point I'm down to the subatomic level. I think I just saw a quark go by.

Well the first thing you know ol' Jed's a millionaire. Kinfolk said, "Jed move away from there." Said, "Californy is the place you ought to be." So they loaded up the truck and moved to Beverly. Hills, that is. Swimmin' pools. Movie stars. Corona virus.

You can tell the age of a tree by counting its rings. You can tell the age of a person by counting the number of times they say something anachronistic. For example, if I start talking about Compact Discs, kids will instantly identify me as being, uh, mature. They will make snide remarks about the La Brea Tar Pits and mastodons. Kids can be cruel. Ask me how I know.

I think something important is happening to movies right now. Not in their content or marketing, but in their distribution. Of course, what we're talking about is a shift, arguably a permanent shift, away from theatrical distribution, and toward home distribution.

Alas, poor Compact Disc! My heart is heavy, I cannot lie. It's come to this. Birds. Angry Birds.

You are probably familiar with the Chinese proverb: “May you live in interesting times.” One could debate the meaning of that expression; it may well be intended as a subtle curse. Certainly, no one can dispute that we are now living in interesting times. Maybe topsy-turvy times is a better way to describe it. Things that formerly were good (hugging) are now bad, and bad things (wearing a mask in a bank) are now good. Similarly, people are wondering if formerly sturdy business models are now shaky. Which brings us to Quibi.

You've read the poem, and maybe recited it yourself. But would you like to hear a recording of the bugle call that sent the troopers of the Light Brigade into the Valley of Death, played by the bugler who rode with them?

The coronavirus is a global tragedy. No one yet knows what the final cost will be in human lives. Some of the estimates are truly sobering. The illness, and fear of contracting it, will also precipitate changes, temporary and perhaps long-lasting, in our lifestyles.

You buy a product. It functions well for a few years, and then its warranty eventually runs out. Clearly, you are now responsible for any repairs. The manufacturer then kindly updates the product’s firmware and…wham! It’s suddenly dead in the water. Is the manufacturer now responsible for repairing or replacing it?

Okay. I get it. Contemporary electronic devices are more powerful than old-timey electronic devices. A software engineer recently estimated that a USB-C charger has more computing power than the guidance computer on the Apollo capsules that took men to the moon (shown above). Awesome. But I still have an axe to grind.

“It's not you. It's me.”
“We can still be friends.”
“I think you love me more than I love you.”
“You should be free to meet your special someone.”
“I'm so sorry, but my cat just doesn't like you.”

How many times has this happened to you? You become deeply attached to someone, and everything is just wonderful, and you sincerely hope and believe that you'll stay together forever. Then suddenly you are hiring a lawyer, and they hire a lawyer, and you realize the honeymoon is over.

My plan for world domination is simple: vacuum cleaners. Of course, as with any fiendishly clever plan, mine has certain nuances. And although it does not involve laser beams, piranha, or secret lairs inside volcanoes, I think you will agree that my plan is quite diabolical.
