Very true. As a poor second option, if he is working from known fixed IP locations, he could have used a packet filter to allow access only from them.

If he is roaming freely, he had no business leaving port 5900 world accessible.

All this micro-management of these standards only serves to confuse people and ultimately causes entry errors and wastes time. Go find the relevant XKCD comic on your own.

I personally miss the Plato IV Plasma Terminal Keyboard - https://codex.retro1.org/plato:tutor:plato_keyboard and http://xahlee.info/kbd/plato_iv_keyboard.html . Those keys on the right with represented many common functions. But the entire keyboard was designed for a future where computers would facilitate many worlds, not just a replacement for a typewriter or calculator.

My iMac Pro 2017 is an Energizer Bunny. I got almost 10 years from by MacBook Pro.

How about lots of similarly painted cheap decoys!?

There was a Star Trek book (The Abode of Life?) that had a planet that where the communication was mostly confined to the planet. I think Uhura detected the planet from the background noise.

I trust that most batteries from iPhones are currently recycled through proper means either by Apple or third party firms.

I don't know how most people will dispose of user replacement batteries, but I suspect the recycle rates will be lower. If you want to ensure higher rates you also need to do something they do in the USA for car lead acid batteries. Charge a deposit fee on the new battery that is returned only when the battery is turned into a valid recycling entity.

"...When you see “libsodium,” you must context-switch from problem-solving mode to detective mode: “What does this do? Let me check the README. Ah, it’s a crypto library... "

I would not mind the command names whose etymology was complex or inspired, if the README files would do a better job of giving context and function. Even though I have a wide set of wheelhouses in computer systems, I frequently encounter README files that still leaves me saying "Huh?". I shouldn't have to google three levels down before I get a clue.

The Lafayette HA460 6M AM transmitter used a 6CW4 Nuvistor as a preamp. Mine survived a lightning strike to my 6M beam, which melted the Gamma Match and destroyed the front end harmonics filter. All tube, expect for a set of DC inverter transistors that allowed for mobile operation. Relatively good RF sensitivity for an AM rig of the era.

Gingerly repaired it served me many years in the late 1960's and still sits in the shack. Sporatic-E was strong in those days, to the extent you could easily DX low channel TV channels cross country. I turn it on every few months for 10-15 minutes in an attempt to keep the electrolytic capacitors polarized.

"Tau Zero" by Poul Anderson

Is it the same universal every time? If so, see you later alligator.

When we did it in high school (70's) we just used compound that had a long chain (soap?) and only one end dissolved in the water. It was very easy to measure and calculate the size of the molecule . We had a series of these simple experiments. Another I recall was measure the speed at which certain volatile compounds moved through the air.

I definitely learned that all science doesn't have to involve complex equipment.
