Comment It's Simon Tatham's fault (Score 1) 138

Because the PuTTY devs are unemphatic whiners who refuse to implement window transparency. Thus, we need two screens, in order to stimulate the brain hemisphere that's coding in Emacs, and the other hemisphere that's watching films. https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.chiark.greenend.or...

Comment Re:Capacity is not the same thing as generation. (Score 1) 240

You get a maximum of 6 hrs./day equivalent nameplate capacity per day in the Mojave desert, =25%. Any time there are clouds, it's much less. Anyplace other than deep desert, it's more like 4 hrs./day over the course of a year, or worse for high latitudes. It's due to geometry, the angle of the sun, and there won't ever be a fix for ground-based solar.

The United States detonated an experimental device in the 1955 Operation Teapot "MET" test which used a plutonium/U-233 composite pit; its design was based on the plutonium/U-235 pit from the TX-7E, a prototype Mark 7 nuclear bomb design used in the 1951 Operation Buster-Jangle "Easy" test. Although not an outright fizzle, MET's actual yield of 22 kilotons was sufficiently below the predicted 33 kt that the information gathered was of limited value.[9][10]

The Soviet Union detonated its first hydrogen bomb the same year, the RDS-37, which contained a fissile core of U-235 and U-233.[11]

In 1998, as part of its Pokhran-II tests, India detonated an experimental U-233 device of low-yield (0.2 kt) called Shakti V.[12][13]

Comment Re:Is this not the era of Pi? (Score 1) 117

Agree - I was excited about the Pi and active on its forum up until I saw the initial board layout with connectors scattered hither and yon, which negative impression was only reinforced by the undocumented Broadcom chip and weird boot process.

Thanks for the recommendation of the ESP8266, it looks like it has pretty useful assortment ofdev boards, though for motor control looks like it might not be as well adapted as something like the BeagleBone Blue, which though it runs Linux on ARM has two additional "real-time unit" processors and can control 4 DC motors + 8 servos, plus it has a 9axis IMU + baro.&temp.. (Servos are incredibly cheap and good these days, $2.50 &up, less than $10 for 11 kg-cm torque(strong), 0.16s/60deg. (fast) check out HobbyKing)

Comment Re:Illegal aliens the root cause (Score 1, Interesting) 498

"You mean those immigrants from Mexico that have a far higher vaccination rate than the US?"

Because vaccination often wears off and isn't 100% effective, many measles cases are among vaccinated people. The far more serious Ukraine measles epidemic, with ~20x the cases in 1/7th the population, directly followed a measles vaccination campaign where the 2nd-dose vaccinated proportion of 6-year-olds tripled in a year, from 31% to 95% 2016-2017. The MMR vaccination was not only ineffective, it quite likely caused the epidemic.

"It has been proven over and over..."
Liar. It's not just illegal immigrants, to be sure - legal immigrants are also spreading epidemics.

Summary of CDC report: "2018: The U.S. experienced 17 outbreaks in 2018. Three outbreaks in New York state. New York City, and New Jersey, respectively, contributed to most of the cases. Cases in New York and New Jersey occurred primarily among unvaccinated people in Orthodox Jewish communities. These outbreaks were associated with travelers who brought measles back from Israel, where a large outbreak is occurring. Eighty-two people brought measles to the U.S. from other countries in 2018."

The current outbreaks are in Arizona, California, Colorado, Connecticut, Florida, Georgia, Illinois, Indiana, Kentucky, Maryland, Massachusetts, Michigan, Missouri, Nevada, New Hampshire, New Jersey, New York, Oregon, Texas, and Washington. These are all high immigration states, legal and illegal. 2014 had 3x the cases of any other year from 2010-2017, and the source of the outbreak was the Philippines. 75 of 2017's 120 cases came from a single outbreak among Somalis.

Immigrants to the US from 3rd world countries spread epidemic disease beyond doubt, no epidemiologist will deny it - in fact they are the main source, travelers being the other and far less frequent origin of epidemics.

"One (inefficient) way to represent any 3D volume would be as a union of spheres..."

Representing 3-D models as spheres can be quite efficient using Conformal Geometric Algebra, which also uses the same representation for points (0-radius sphere) and planes (infinite-radius spheres). It also has point pairs (1-d spheres), flat points (flat point : point pair :: point : sphere), circles (2-D sphere) and lines (infinite-radius circles. It does this by using two additional dimensions and Clifford Algebra, but using it is quite simple, even middle schoolers should be able to use it. 3D Euclidean Geometry through Conformal Geometric Algebra (a GAViewer tutorial)

This technology applied by the British company Geomerics and incorporated in game engines enabled real-time radiosity lighting in games, for instance letting arbitrarily-placed fireballs light up the scene. Some of the best papers on Geometric Algebra are by the Cambridge professor founders of Geomerics such as Chris Doran. See University of Cambridge Geometric Algebra Resources

Comment Re:Patent plants? Well, yes. (Score 1) 223

Only asexual reproduction such as cuttings - not reproduction by seed - is eligible for plant patent in the US. (There are 3 types of patents in the US: Utility, Design, and Plant. Utility patents are what we think of as real patents, protecting against copying functional aspects of a machine or process. Design patents cover appearance only.) Only in the 1980s did the US start granting utility patents for bioengineered plants and animals, and that was done by the PTO without new law from Congress. Since then the Congress has acquiesced, but hasn't made the law as clear as for plant patents. There needs to be a new fourth category of patent added or the existing plant patent type needs to be completely overhauled to deal with DNA engineering explicitly and sensibly.

None of this matters for the case at hand in India, other than US influence on India's laws via international treaties.

Even if they can make their patent claim stick, PepsiCo shouldn't be allowed to make the farmers into their peons by forcing to farmers to grow only the patented crop if they grow any of it at all. They shouldn't be allowed to impose any conditions other than payment for their seed, in particular, they shouldn't be allowed to force the farmers to sell their whole crops only to PepsiCo. That puts the farmers completely at the mercy of the corporation, far more than being an employee, while the corporation has far less obligation than to an employee. It is peonage, bondage.
