This was made public a number of years ago.

The USB and Firewire interface on the 10 year old J-Bus (UltraSparc IIIi) had memory management for the I/O interfaces as well as the CPU. The DMA from external interfaces could only access memory granted to it by the OS.

One of the most useful instances of social media and Googles apps was a series of postings on a San Diego Union Tribune discussion board related to the fires. The poster was embedding links to a Google Maps page with frequently updated fire perimeter along with reports of where the evacuation centers were being set up. It was very useful as my family and I were about an hour from needing to evacuate when the winds shifted.

Having driven in Montana, that's very true for the eastern portion of the state.

How in the hell do you think dew gets deposited on grass, cars, etc? Dew forms when the surface temperature drops below the dew point of the air, which cannot be any higher than the ambient air temperature.

FWIW, a problem from my engineering heat transfer course indicated that frost can form when the air temp is 9F/5C above freezing.

The microlayer is also highly reflective in the near infrared range as a not insignificant portion of the sun's radiation is in the near IR. It is the far IR that the material highly absorptive/emissive.

Michelson did a lot of work on measuring the speed of light, one of the last measurements he did involved a mile long vacuum chamber. As with many experimental physicists, he had to be an accomplished engineer as well in order to conduct his experiments.

Sounded like someone combined notes from a scientific lecture on the history of the earth with a "young earth" creationist's history of the earth.

And fiber has even more bandwidth than copper.

Your point is correct about fixed links providing far more bandwidth that what can be provided by any kind of wireless link. The drone concept only make sense in places like the lightly populated areas of the US or similar countries where customers are too far apart to make wireline or fiber communications affordable. The low altitude with respect to satellites means that the link frequencies can be re-used more frequently.

I remember one of my brother's first issues (Apr? 1964) of Boy's Life having "Sunjammer" as the cover story. AC Clarke later expanded the story under the name "Wind from the Sun". FWIW, Boy's Life is one of the magazines digitized by Google Books and you can look up the issue in question.

Actually, you're the one who comes across as being ignorant.

Baseload generation is generation is considered to be the lowest incremental cost dispatchable power source. No form of generation has 100% up time, but a well run plant will have very little unscheduled down time. The variability of wind is a huge problem when wind generation becomes a significant portion of total generation at a give moment, requiring a large amount of spinning reserve to keep the grid stable.

FWIW, the limiting factor in power output of an AC generator is not conductor heating, rather it is the amount of power that can be generated without the generator pulling out of synchronism, especially under fault conditions.

What Edison invented was an incandescent light with a high enough resistance to make it possible to powered by a central station, along with the central station, a means of metering current, etc. Edison's work was mostly independent of Swan's.

While this book is not a Tesla biography, it does give a good picture of how Tesla fit in with the beginnings of the electric power industry. The book does give Tesla proper credit for the invention of poly-phase AC and the induction motor, but also points out that Stanley and Thomson were working on AC distribution before Tesla along with a lot of refinement on the induction motor being done by Benjamin Lamme.

It is the likes of Lamme and Steinmetz that are the unsung heroes of the electrical age.

When the Vatican decided to digitize their archives, they chose to store the mages in FITS format for pretty much the same reasons. One thing FITS doesn't address is preventing unauthorized access to the data.

In 1972, SAN to OAK was $24.50 on PSA with no restrictions. Equivalent fare on Southwest is ~$260, cheaper fares are available but come with restrictions.
