If you're interested in the current state of the art, read this article from the Publications of the Astronomical Society of the Pacific (April 2013). It describes the hardware and software used by the Pan-STARRS team to detect asteroids automatically in data taken with their 1.8-meter telescope on Hawaii and its 1.4-gigapixel CCD camera.

Comment Re:Startups Aren't Really Job-Creators In Practice (Score 4, Insightful) 303

Aggregating $19B in wealth in the hands of 50 people plus a handful of investors is indeed not the way to create jobs. It slows down the flow of money within the broader economy. I'm sure those $20M homes in Woodside and Los Altos Hills and Seacliff are worth every penny.

These megadeals also have the effect of creating a startup lottery environment where anyone can put together a ten page business plan and the "trend du jour" and try to make out like bandits. This is what led to the first dotcom crash and will also eventually lead to the second crash at some point. Anyone who makes an alternative to this content with having the user watch ads in the background every ten app starts will murder Whatsapp because $0 is cheaper than $1.

I think it's also important to note that Eric Schmidt wholeheartedly approves of this deal because I suspect he thinks it's to the ultimate detriment of Facebook, and a blessing \for Google in some ways. Much like unbridled immigration is to existing workers in this country for his business.

Comment Not to mention that the parties themselves cheat. (Score 4, Interesting) 273

At present we have two parties that are both owned, for the most part, by the same people, and kept in power by gerrymandering and the systemic weakness of first-past-the-post elections.

Further, the people in control of the major parties themselves cheat when someone not of their faction tries to go the primary/caucus root. They change rules in midstream, miscount, break meeting rules, physically attack supporters of opponents, pass out bogus delegate slates, and a host of other dirty tricks.

For a list of the things the Republican have done to just one challenger in the last two cycles, check out the archives of any of the several sites where Ron Paul supporters congregate. (For example, The Daily Paul.)

The Democrats do this as well. (The riots in Chicago in 1968 were largely a public reaction to the party machine repelling a primary effort by Gene McCarthy, popular with the antiwar movement, in favor of Hubert Humphrey. The Paul/Romney nomination battle was eeriely similar.)

Comment The fed killed drug research for decades. (Score 5, Interesting) 221

This has been a long known fact,

Some of this was known back in the '60s and '70s. But the federal government decided to suppress it. In particular: Any drug with side-effects that were pleasant was considered a threat to the status quo of governance - a way for productive people to achieve happiness without driving industrial profit and/or part of a Communist conspiracy to rot the "Free World"'s moral fiber.

There was a period where researchers would only get new grants if the conclusions of their studies stated that the drugs - psychedelics, marijhuana, etc. - were useless for medical purposes and/or dangerous. (The papers in Science, for instance, were often pathetically hilarious. The reduced data said one thing, while the conclusion said the opposite.)

Meanwhile the government (notably with such things as the FBI's COINTELPRO program) smeared those (formerly highly respected scientists) who had been proponents of finding uses for them (especially those who had tried to use them to augment intelligence and experimented on themselves - often with bizarre results). The most prominent of these was Timothy Leary, though there were a number of others.

Somewher in there the drugs were added to various "schedules" and banned from medical use.

After a couple years of this, with any actual benefits buried in the noise, the government declared that it was "settled science" that there were no useful treatments using these drugs and stopped issuing new permits for their use in new research projects. (It's very much like research into global warming: You can't convince people on either side because the research is suspect due to the government becoming involved and pushing its horse in the race.)

Then the government declared acts related to banned-drug trafficing, possession, and use to be "serious" crimes and imposed passed mandatory minimum sentences - recreating the scenario of alcohol prohibition, funding organized crime, filling up the prisons, and lining corrupt police personell's pockets with graft money. Then it passed RICO and created the same financial incentive structure that fueled the Spanish Inquisition - driving ever-increasing anti-drug activity and blocking attempts to repeal drug bans.

And that's where it stood for decades. Negligible work on uses for the chemicals - either by organized research or private self-medication (with drugs of uncertain content and quality).

So while Moore's Law drove the computes from giant cabnets filling floors of office buildings to chips in everything under the sun, work on a nimber of categories of drugs stagnated.

The canabinoids of Marijuana, alone, have a number of apparent (but not adequately researhed) benefits:

  - They appear to be a specific treatment for Post Traumatic Stress Disorder (which, itself, seems to be a result of undermeidcation for pain - also driven by the "drug war").
  - Canabinoids (including at least one which does not produce a substantial "high") also appear to be a successful treatment for a debilitating form of childhood epilepsy.
  - Parkinson's disease eventually kills, not directly through loss of dopamine, but by the body's attempt to compensate for it by fouling up a system that uses the recently discovered endocanabinoids as neurotransmitters. (These are the chemicals that THC and its relatives mimic, much as opioids mimic endorphins.) This ends up with loss of memory and loss of appetite, and the victim starves herself to death. Canabinoids may help alleviate this and/or prolong life, (if only by reducing the tendency to self-starvation by inducing "the munchies").
  - Canabinoids have been claimed to arrest the progress of several cancers, including a brain cancer.d
  - Canabinoids have long been used for reducing the nausea of chemotherapy, easing self-starvation in cancer patients. (Similarly with side-effects of anti-AIDS drug coctails.)

I could go on.

But "more research is needed" to determine which (if any) of these effects are real, turn them into practical treatments, and deploy them. And it's not going to happen smoothly and rapidly with the government continuing to interfere.

Comment Re:Selling assult weapons (Score 4, Insightful) 310

However, the term "assault weapon" is more fuzzy, at least according to Wikipedia.

Wikipedia has it right, in its own "being unbiased in the wording" way.

"Assault Rifle" is a technical term in warfare. It first applied to a particluar select-fire rifle short enough to avoid getting hung up when popping up through the hatch of a tank to fire at surrounding infantry (or otherwise going through tight spaces), and since has been applied to others with simiilar characteristics. This trades away some accuracy for rapid fire and rapid movement.

"Assault Weapon" is a term invented by antigunners and defined in particular laws, to confuse the population about proposed gun control laws by making them appear to be banning military design Assault Rifles when they actually ban a hodge-podge of civilian guns based on some arbitrary (and juristiction-specific) set of characteristics typically unrelated to any objective standard of danger or functionaity.

Her point is teach the concepts, teach the patterns, teach kids how to find patterns, and how to internalize mathematical knowledge.

Submission + - Why Can't Fish Swim Deeper than 8000 Meters? Their Brains Explode

sciencehabit writes: Ocean-going fish can’t live any deeper than 8200 meters, according to a new study. A team of biologists say the threshold is set by two competing effects of trimethylamine N-oxide (TMAO), a chemical in fish cells that prevents proteins from collapsing under high pressure. While fish should need more and more TMAO to survive ever greater depths, higher concentrations of the compound also draw in more and more seawater through osmosis, the process by which cells regulate their water content. In the deepest waters, high TMAO levels reverse osmosis pressure, swelling brain cells to the point that they stop working and, in principle, bursting red blood cells open.

Comment Re:Powerline networking firewall (Score 1) 62

I'd really like to be able to install something on the lines leaving my breaker panel that acts like a firewall and blocks any kind of network communication over powerline.

1. Get some electrical-noise suppression ferrite toroids and some ceramic capacitors at your local electronics store. (.005 microfarad at a minimum of 600V would be good for the caps. 1000V or higher on cap used for 240V circuits.)

2. In your fusebox connect a cap from each breaker's hot output to the nearest ground bus, keeping the wires as short as possible. (You want them downstream of the breaker so they blow the breaker, rather than start a fire, in the very unlikely chance that one fails shorted.) On 220v loads hook the cap between the two hot wires (red and black in the US).

The cap wires are too small to carry the current in case of a short, so get some tiny 1A pigtail fuses and wire them in series on the hot side (either side in the 240V both-are-hot case). Put plastic insulation rated at least 600V over (at least) the hot side wires and the fuse. (You can get such insulation, of adequate voltage and temperature ratings, by stripping the insulation from a spare piece of electrical wiring.)

3. In your fusebox disconnect the circuits, one by one, both hot and neutral. On each run the hot and neutral lines through a ferrite toroid core in opposite directions and reconnect the . For a 220V circuit run the two hot lines through the ferrite core, again in opposite directions, and ignore the Neutral. If you have multiple loads on a breaker, you can use separate toroids on each load or a single one on from two to all of them: Run the hot wires all one way through the toroid and the neutral (or red-hot on 240V) the other way.

This puts inductance in series with the signal and capacitance shunting it, forming a low pass filter. The low-frequency power will get through just fine and the high frequency networking signals will get stopped.

Putting cores on the main feeds also works, and takes fewer cores. You can also put one on each of the hot wires, separately, rather than using one with the wires crossed through it. You can get big ones that are split, intended to be clamped over a computer signal cable to prevent it from acting like an antenna, which you can clamp onto the wires without unhooking them.

Don't bother putting the two haves of the circuit through the core in the SAME direction, as you would with the signals in a cable or power cord if you clamped a core around the whole thing. This keeps the common-mode (both wires go positive or negative together) from propagating past the core, but the differential mode (one goes positive while the other goes negative), which is what power line networking uses, goes right through.

Note that putting this stuff in your fusebox may be against code, and void your fire insurance. The capacitor wiring may also be problematic for creating hazards if not done properly (insulated with "spaghetti tubing" on at least the hot side, hot side cut short, a little fuse (1A or so) in series, etc.).

Two instances just from the public record: First there's the Homebrew Computer Club, founded in '73, which includes a number of leading lights in the Silicon Valley part of the industry, including Jobs and Woz.
