Angular resolution through the Atmosphere has been solved with adaptive optics and advanced mathematical techniques.

Unfortunately, nothing can remove the temperature of the atmosphere (which affects infrared imaging), or the absorption of many wavelength bands.

Only maybe in the dense core of a galaxy because incident radiation falls off with the square of distance.

The nearest star to us after the Sun is ~4ly away, or ~250k AU. The Sun would have to be ~63 billion times brighter to give the same incident radiation at 250k AU, and that is just a typical distance between stars in our neighborhood . The Sun is also brighter than the average star, especially the older stars that congregate near the galactic center.

Galaxies can easily have 1 trillion stars but they are usually so spread out as to make this impractical. This is also why the Milky Way, Triangulum, LMC, SMC, and Andromeda (nearest galaxies) are so faint to the naked eye.

Nobody who had to work with 6509's/7609's at an ISP is shedding a tear over this.

Someone (Richard Steenbergen?) once made a joke that we should take the last 6509/7609 and launch it into orbit to celebrate.

It's not that they weren't popular. At one point in the mid 2000's they appeared to make up about 1/3 of major internet routers (if you looked around a carrier hotel). This was due to their extremely low cost compared to actual high end routers. While they had serious limitations and were notoriously sensitive to "IOS roulette", somehow you could just make them work.

I remember Hale-Bopp in 1997. At it's peak it was so bright you could easily see it from inside a brightly lit restaurant, looking out a window 20 feet away.

> Never have more than 79 characters per line Never write lines longer than 79 characters.

I'm sorry, I just cannot do this. I start to feel somewhat guity after 300 characters but 80 feels like an Atari 800.

I bought a CD from CDNOW over Telnet in the early 90's!

I also remember telnet BBS's became popular for a few years when I was in college 91-93.

> Mistake it may well be, but the fact remains that this sense of the word is in widespread use today, and may be found often enough in well regarded and highly edited, publications.

I would say you are most likely to find this usage of that word in well regarded and highly edited, publications.

I just had an idea that may be my worst technology idea ever.

Assemble some unstable atoms (that decay into carbon) into the desired cubic structure. When they decay you have a diamond.

The problem with this is that if it can decay fast enough (even with outside neutrons) it will be too hot (pun intended), and if it decays slowly enough it will take too long. Depending on the source isotopes and process it could also result in a radioactive diamond! Also, the heat of the process would have to not change the crystal structure.

However, some day when we master quarks and the weak interaction we might be able to do this quickly and safely.

I did indeed mean a singe, byte-valued parameter indicating angle (similar to the single angle parameter of a mechanical polarizing filter)

Full polarization and phase info would be great to have also but probably not necessary for reflection suppression. And yes purely circular polarization would be undefined in this scenario but again not common (possible?) with reflections.
