Study: Chimpanzees Have Evolved To Kill Each Other

Muad'Dave Re:No surprise (211 comments)

... the most violent and aggressive species on earth?

When's the last time you chased down and killed your food? When's the last time you actually used physical violence against another human, much less a prey species?

We're our most violent in aggregate (war). Most recent 'wars' were/are over ideals or perceived threats (we don't like what you're doing to your people, so we're gonna invade), not actual physical threats (WWII was an actual imminent threat). We're not so bad when we don't _have_ to use violence.

Is the Tesla Model 3 Actually Going To Cost $50,000?

Muad'Dave Re:Still pretty affordable (388 comments)

The uController could easily run for several _years_ on a pair of D batteries. It sleeps for all but a single second out of the day, and wakes up to 'press' the go button. You could just as easily power it from a wall tumor across the 220V line powering the charger (many/most are 110/220 tolerant).

The fish timer would be powered from 1 leg of the 220 V circuit to the neutral to provide 110V as it expects.

My point in posting was that there are alternatives to having to switch the full 220V / bazillion amp charging current directly. Sometimes subtlety wins out over brute force :-)

Is the Tesla Model 3 Actually Going To Cost $50,000?

Muad'Dave Re:More importantly (388 comments)

My Mini is perfectly average, then. It's a 2003 (got it in March), so it's almost exactly 11.4 years old and only has about 84k miles on it. My previous car was 17 when I passed it on to a local enthusiast. It had something like 77k miles on it (A 1987 Conquest TSI - cool car!).

Is the Tesla Model 3 Actually Going To Cost $50,000?

Muad'Dave Re:Still pretty affordable (388 comments)

The average price of gas in southern California is currently ~$3.50 ... the most fuel efficient large BMW in the US, the 535d, only achieves 30MPG ...

Isn't that a Diesel? I bet Diesel fuel is higher than the ~$3.50/gal you quoted.

A fish tank timer (or more likely, a tiny microcontroller) across the "Start" button leads would work just fine. There's more than 1 way to skin that cat.

Scientists Twist Radio Beams To Send Data At 32 Gigabits Per Second

Muad'Dave Re:Microwaves and 2.4 GHz (120 comments)

The special part about 2.4 GHz is that it's a the first available world-wide ISM band that is anywhere near frequencies that can be generated with high enough power in a countertop form factor to heat anything. Magnetrons are not known for their spectral purity or frequency stability, so using an ISM band that's 100 MHz wide also gives you a lot of leeway for frequency excursions for what little RF is actually leaked out of the oven.

Universal Big Bang Lithium Deficit Confirmed

Muad'Dave Re:Quite accurately? (170 comments)

I guess what I was trying to get across was that matter doesn't have to 'show up' as other matter - it could also be converted to energy via matter/anti-matter annihilation. Probably not a likely scenario, just pointing that out.

Universal Big Bang Lithium Deficit Confirmed

Muad'Dave Re:Quite accurately? (170 comments)

... If we were just short a bunch of lithium, all of the other elements would be higher, percentage wise ...

Perhaps there was some mechanism that caused the 'missing' lithium to be created as anti-lithium that would've then been annihilated. No need to invoke additional regular matter.

NRO to declassify Cold-War Spy Sat Tech

Muad'Dave Muad'Dave writes  |  about 3 years ago

Muad'Dave (255648) writes "The National Reconnaissance Office is set to reveal details of two of the cold war's most capable spy satellite programs on September 17th — the GAMBIT and HEXAGON projects, aka the keyhole KH-7, -8, and -9 satellites. These bus-sized sats provided critical imagery during the height of the cold war, and were likely the inspiration for the movie "Ice Station Zebra".

The article links midway down the first page provide a fascinating look into the world of real spy-vs-spy, cloak-and-dagger intelligence gathering."

US Air Force secret X-37B orbiter lands

Muad'Dave Muad'Dave writes  |  more than 3 years ago

Muad'Dave (255648) writes "The US Air Force's secret X-37B orbiter landed at Vandenberg AFB early this morning. Amateur satellite watchers determined the orbit and detected several orbital maneuvers. From the press release:

30th Space Wing Public Affairs

12/3/2010 — VANDENBERG AIR FORCE BASE, Calif. — The U.S. Air Force's first unmanned re-entry spacecraft landed at Vandenberg Air Force Base at 1:16 a.m. today.

The X-37B, named Orbital Test Vehicle 1 (OTV-1), conducted on-orbit experiments for more than 220 days during its maiden voyage. It fired its orbital maneuver engine in low-earth orbit to perform an autonomous reentry before landing.

The X-37B is the newest and most advanced re-entry spacecraft. Managed by the Air Force Rapid Capabilities Office (AFRCO), the X-37B program performs risk reduction, experimentation and concept of operations development for reusable space vehicle technologies.

"Today's landing culminates a successful mission based on close teamwork between the 30th Space Wing, Boeing and the Air Force Rapid Capabilities Office," said Lt Col Troy Giese, X-37B program manager from the AFRCO. "We are very pleased that the program completed all the on-orbit objectives for the first mission."

OTV-1's de-orbit and landing mark the transition from the on-orbit demonstration phase to a refurbishment phase for the program.

The Air Force is preparing to launch the next X-37B, OTV-2, in Spring 2011 aboard an Atlas V booster."

Target pharmacy begins scanning driver's licences

Muad'Dave Muad'Dave writes  |  more than 4 years ago

Muad'Dave (255648) writes "This evening I picked up my regular prescriptions at my local Target pharmacy. As I was paying for them, the cashier asked to 'see my ID'. That was not typical, but I assumed she was going to verify the photo. Before I could stop her, she flipped it over without looking at the front and scanned the 2D barcode on the back. I asked her why she did that, and her answer was that the system 'required' it.

I went to the customer service desk and asked them why they thought they were entitled to scan my license. Their first answer was that it was a convenient way to validate my birthday, and that was all that was on the 2D barcode. When I mentioned that I know there's more data than that, she then said that it was a convenient way to verify that the ID was present. I mentioned that verifying the presence of an ID required more data than the DOB, and she agreed, contradicting her earlier statement that all they scanned was the DOB.

The is a Federal law addressing who can and cannot scan licenses, but it's so full of loopholes as to be useless.

Apparently I'm not the only one bothered by their attitude on privacy.

Have you been subjected to this invasion of your privacy by Target?"

Cheap, super-efficient LEDs on the horizon

Muad'Dave Muad'Dave writes  |  more than 5 years ago

Muad'Dave (255648) writes "According to this article, cheap Gallium Nitride LEDs are now possible, thanks to a process that controls the rate at which GaN shrinks when cooled, making it possible to grow GaN on silicon.

"They included layers of aluminium gallium nitride in their LED design. These layers shrink at a much slower rate during cooling and help to counteract the fast-shrinkage of pure gallium nitride. These LEDs can be grown on silicon as so many other electronics components are."

"A 15-centimetre silicon wafer costs just $15 and can accommodate 150,000 LEDs making the cost per unit tiny. That levels the playing field with CFLs, which many people only ever saw as a stopgap solution to the lighting problem.""

The Re-Entry of ATV: One Final Experiment

Muad'Dave Muad'Dave writes  |  more than 5 years ago

Muad'Dave (255648) writes "The SETI Institute, in cooperation with the European Space Agency is organizing a mission to record the fiery breakup of the ATV/Jules Verne spacecraft as it re-enters Earth's atmosphere on September 29th.

From the article:

A documentation of the breakup process could help validate the models built to study how that fragmentation evolves in a series of disruptions of major components. At reentry into the atmosphere, ATV would execute one final experiment before the mission completion. Our experience with meteor spectroscopy carried the promise of perhaps being able to identify some of the fragments from their radiation signatures. The ATV-1 "Jules Verne" Multi-Instrument Aircraft Campaign was born. "

Opportunity Takes a Dip Into Victoria Crater

Muad'Dave Muad'Dave writes  |  about 7 years ago

Muad'Dave (255648) writes "From the NASA News Release:

Today, NASA's Mars Exploration Rover Opportunity entered Victoria Crater for the first time. It radioed home information via a relay by NASA's Mars Odyssey orbiter, reporting its activities for the day. Opportunity drove far enough in — about four meters (13 feet) — to get all six wheels past the crater rim. Then it backed uphill for about three meters (10 feet). The driving commands for the day included a precaution for the rover to stop driving if its wheels were slipping more than 40 percent. Slippage exceeded that amount on the last step of the drive, so Opportunity stopped with its front pair of wheels still inside the crater.

This marks the beginning of perhaps the greatest 'Opportunity' for new discoveries on Mars."
