LAPD Gets Some Hand-Me-Down Drones From Seattle, Promises Discretion 108

After Seattleites objected to the local police department's plan to deploy unmanned aircraft, that plan was withdrawn. Now, it seems, Seattle has found a willing recipient for some of the drones that it no longer has use for: the Los Angeles Police Department. From the linked article: "The Draganflyer X6 aircraft, which resemble small helicopters, are each about 3 feet wide and equipped with a camera, video camera and infrared night-vision capabilities. In making the announcement, however, department officials were at pains to make it clear the LAPD doesn't intend to use the new hardware to keep watch from above over an unsuspecting public. If they're used at all, the remotely controlled aircraft will be called on only for "narrow and prescribed uses" that will be made clear to the public, the statement said."

Comment Re:Classify net access as a utility? (Score 5, Informative) 343

No, not unless you would like your Internet access technologies refreshed and upgraded about as often as your water pipes or electric lines are. Which is to say approximately never.

In the past 10 years, I have never turned on my water tap and had no water come out. In the past 5 years (which is as far back as I have log files from my UPS), I've experienced 2 power failures lasting longer than a few minutes (I recorded 7 outages lasting less than a few minutes, but some of those were when I unplugged the UPS or turned off a breaker to do some electrical work), one was a regional power outage, and one was caused when a car accident took down a utility pole.

However, I experience regular internet outages, the last one was last week, and lasted for 3 hours, cable TV was fine, but internet (for me and a neighbor down the street) was out. It took 30 minutes to get someone at Comcast to realize that there was a problem, but they had no idea what was wrong, nor any ETA for a fix.

So I *wish* my internet connection was managed as well as water and power.

Comment Re:AWS is too expensive (Score 1) 142

1) I guess it goes down until it can be fixed under warranty (same or next day depending on purchase option). Redundancy is expensive. What happens when your single instance of AWS goes down with an "oops amazon is having problems with a datacenter" message?

Well i guess the same thing that happens when the datacenter that my 1U server is colocated in goes down -- I either bring up the server n a DR region (which I can set up nearly for free with AWS), or wait until the datacenter problem is fixed. In the past 2 years, haven't experienced a single multi-AvailabilityZone outage with Amazon, and only 2 short single AZ outages that resulted in no loss of service since my servers are split across multiple AZ's. I've never had to fail over to the warm-spares in a separate region (other than during testing).

3) Reserved instance is cheaper, but at that price still more than a dedicated server and the server typically comes with a 3 year warranty and will likely last past that (Dell will warranty for 6 years). Assuming it only lasts 3 your cost for running on AWS is nearly 3 times higher even when figuring in an improved warranty and OS licensing. I concede that short duration projects or very spiky loads are a great use for the cloud, but long running relatively even loads simply don't make sense form a cost perspective, nevermind the fact that you now lose access to your database if your wan connection goes down (unless you build out multi-wan, but there is yet another expense).

Coloc space is not cheap, so don't forget to factor that into the costs. Running a datacenter in the office is even more expensive due to the costs to add the needed redundancy (power, cooling, internet) to an office tower.

The point still stands. If it's not 100% then someone who is immunized can catch and STILL give it to you. Thus both immunized and non-immunized pose the same threat to you.

The point only stands if you pretend that there's no real difference between an unimmunized person and a immunized person with 0.3% chance of catching the disease, and if you ignore the science behind herd immunity.

How can you get infected if YOU have been inoculated??? So how are they a public risk to you?

Because no vaccine is 100% effective, even if you're immunized, you can still catch the disease.

http://www.historyofvaccines.o...

Why aren’t all vaccines 100% effective?

Vaccines are designed to generate an immune response that will protect the vaccinated individual during future exposures to the disease. Individual immune systems, however, are different enough that in some cases, a person’s immune system will not generate an adequate response. As a result, he or she will not be effectively protected after immunization.

That said, the effectiveness of most vaccines is high. After receiving the second dose of the MMR vaccine (measles, mumps and rubella) or the standalone measles vaccine, 99.7% of vaccinated individuals are immune to measles. The inactivated polio vaccine offers 99% effectiveness after three doses. The varicella (chickenpox) vaccine is between 85% and 90% effective in preventing all varicella infections, but 100% effective in preventing moderate and severe chicken pox.

Further, some individuals are unable to be vaccinated due to underlying medical conditions (allergies, compromised immune system, etc).

Sorry. While I love technology, my not-so-humble opinion is that we're nowhere near the level of reliability needed for a car that's completely free of manual control.

Simply put, having seen the arc of technology advance over the last 30+ years, I still don't trust an automated driver system with my safety. PERIOD.

Millions of people fly in airplanes every day that rely on computer controls (since there is no mechanical linkage between the pilot and the control surfaces). And 30,000 people die each year at the hands of human drivers.

While the real time image recognition may not be quite ready for prime time, it will get there and when it does, computer drivers will be safer than human drivers. Google's driverless cars have already racked up 700,000 accident free miles in autonomous mode (albeit with a human ready to take over). Their car has already surpassed my own record, it's only been about 150,000 miles since my last accident (a car changed lanes into me, while the accident was not my fault, if I'd had computer-like reflexes and perfect awareness of my surroundings to know that the lane beside me was open, I may have been able to avoid the accident by sudden braking and/or making a quick lane change)

NASA Money Crunch Means Trouble For Spitzer Space Telescope 107

Scientific American reports that an ongoing budget crunch at NASA may spell doom for the Spitzer Space Telescope, the agency having "taken stock of its fleet of orbiting astrophysics telescopes and decided which to save and which to shutter. Among the winners were the Hubble Space Telescope, the Chandra X-Ray Observatory and the Kepler planet-hunting telescope, which will begin a modified mission designed to compensate for the recent failure of two of its four stabilizing reaction wheels." Also from the SciAm article: "Until JWST comes online, no other telescope can approach Spitzer’s sensitivity in the range of infrared light it sees. The Senior Review report noted that Spitzer had the largest oversubscription of any NASA mission from 2013 to 2014, meaning that it gets about seven times more applications for observing time from scientists than it can accommodate. ...'The guest observing programs were very powerful because you get people from all over the world proposing ideas that maybe the people on the team wouldn’t have come up with,' [senior review panel chair Ben R.] Oppenheimer says. 'But it’s got to be paid for.'"

Really? Poles and cables? The future is wireless. Actually, the present is wireless. Poles and cables for anything but electricity is archaic. Every time this topic comes up, it always boils down to the poles and cables. Get rid of the poles and cables and you get rid of 99% of this problem.

Then why is Google spending so much money on fiber to the home? As RF frequencies increase (since there's only so much bandwidth available at the lower frequencies - a 100Mhz channel at 900Mhz takes up relatively more spectrum than a 100Mhz channel at 10Ghz), cell sizes decrease due to lower propagation and penetration of the higher frequencies to a point where it takes a Wireless access point at every house (or possibly in every room in the house) to provide equivalent throughput to wired infrastructure.

Comment Re: 2 tons? (Score 2) 56

A pound is a unit of weight and can correspond to any kg mass, determined by the gravity of the place where it is being measured.

Weight is dependent on gravity, mass is not. Welcome to 5th grade science class

Which is why the metric system has separate units for mass and weight/force.

But that's not the case with the pound, it is used for both (sometimes, but not always more specifically as pound-force or pound-mass)

http://en.wikipedia.org/wiki/P...

The pound or pound-mass (abbreviations: lb, lbm, lbm, [1]) is a unit of mass used in the imperial, United States customary and other systems of measurement. A number of different definitions have been used, the most common today being the international avoirdupois pound which is legally defined as exactly 0.45359237 kilograms, and which is divided into 16 avoirdupois ounces.

Don't believe Wikipedia? How about the NIST?

http://physics.nist.gov/Pubs/S...

MASS and MOMENT OF INERTIA: To convert from pound (avoirdupois) (lb) to kilogram (kg)

http://physics.nist.gov/Pubs/S...

FORCE: To convert from pound-force (lbf) to newton (N)

The real world is not always as simple as what you learned in 5th grade science, when your teacher said "The pound is a unit of weight, not mass", he was correct and incorrect at the same time due to the ambiguous nature of the unit.

Ton is already ambiguous, but since it is a USA media article, its safe to assume that they meant what is also known as the short ton, or 2000 pounds. The pound is defined as 0.45359237 kg, so it is, by definition, a unit of mass.

It's not like they "forgot" that users might want to add new books, the inability of any updatable storage was a design requirement to prevent it from being used for espionage or as a channel to inadvertently bring malware aboard a ship.

This is to prevent it being used to smuggle secret military data ashore, take illicit photos, introduce computer malware or record covert conversations.

Though it seems that there are so many ways for a person to smuggle a MicroSD card into a secure area that an eReader is probably not a huge concern.

We have are 12 dev/test servers that I didn't bother to patch because they'll be decommissioned in a month or two along with the rest of the datacenter they are in, and even though they support SSL connections (with a disposable cert from our private CA), they are generally only used with HTTP and have no private data to protect, and are almost completely unused now.

If someone wants to spend time trying to steal the server's private key or steal user data from the server, that's fine with me, I'd rather have them spend time on my disposable server than someone's real server.

SF has put absurd amounts of money into public transit and even you acknowledge it's only just possible to get along without a car there. Few people that live there even attempt it, and fewer still succeed. So despite all the money put into public transit people still want their cars. But people are crowded together so closely already there is barely room to walk, let alone drive.

With current technology it's a dead-end. Instead of building public transit the 'planners' should be figuring out how to reduce population density.

Public transit funding is only "absurd" if you ignore the huge subsidies that go to cars.

30% of SF residents have no car, still a ways to go to catch up to NYC's 55% but that number is growing.

CIty planners have already spent decades planning low density communities across the country, But it turns out that people still need to go to the office -- telecommuting still hasn't fulfilled it's promise of letting workers stay at home, even Google with unlimited technology resources still ships its employees 40 miles from SF to GoogleHQ. It's a lot easier to get people to the office when they live and work in the same high density city than when homes and businesses are spread over a large low density area. You can see this when you look at the difference in transit effectiveness in San Jose versus San Francisco.
