You're correct that it is not a 50% improvement, but because of your bad math (1/3 of 12 is 4, not 6). The real fail is the article which got it wrong with respect to Xeon E5 V2. You can get Xeon E5 V2 chips with 15 cores, so the V3 chips are really only a 20% improvement.

There are a lot of differences between typical recreational use and commercial use. So the recreational vs. commercial is only one small part of the guidelines outlined in Advisory 91-57. The main issue is that recreational model aircraft are flown with line of sight, and any camera is used either just for post flight video or for potential assistance, but not for primary flight. This kind of flight is almost useless for commercial use. A commercial UAS uses the camera as a first person view for actually flying the vehicle. Typically RF power is increased to be able to fly the vehicle much further. This is significantly more dangerous. There is a huge loss in situational awareness. If the camera system fails then you are literally flying blind. The camera is not showing the plane itself so it is more difficult to diagnose the beginning of a failure. When a recreational flyer sees his vehicle failing he can immediately turn it around and since it is not out of line of sight there is a much better chance that the pilot can get the vehicle back or most of the way back. The pilot has full situational awareness of what is under and around the plane/vehicle. Commercial UAS systems are typically higher power, heavier, larger batteries, etc. You really don't want these things flying over your head. Use of them in urban or suburban settings should be carefully regulated.

Are you talking about websites? Because I can't imagine people were all that excited about new telnet, ftp or gopher sites. If you're talking websites then your timeline is a little off. The World became the first ISP in 1989. Tim Berners-Lee created the first website in December 1990, but didn't really advertise the fact (and make a web browser available) until August of 1991.

UUNET was not providing internet connections at that time. They started out as a UUCP service provider, primarily providing email and Usenet feeds via uucp. So sometimes people will say they are the first ISP, just like people will claim Compuserve, Prodigy and AOL were all ISP's back then. But The World was the first true ISP providing access to the Internet, which probably wasn't all that exciting for the general public at that point.

Comment: Re:Too quick to dismiss DSL? (Score 3, Informative) 324

RIght. That nearest hub/station/whatever is called a DSLAM. A DSLAM can be installed near or in your neighborhood and fed by fiber. I have a fiber fed DSLAM in my neighborhood and I subscribe to a 40 Mbit VDSL2 service. I'm less than 1000 feet from the DSLAM, as are most of the people in our neighborhood. The generic "DSL" covers a wide range of service. The fact is that many people can only get 1.5 Mbit (or even only 256 Kbit) service, so they assume that (or 5-7 Mbit, which is the next tier typically available) is the best that DSL can offer.

Comment: Too quick to dismiss DSL? (Score 2) 324

Perhaps you have been too quick to dismiss DSL. I assume that currently your DSLAM is not very close to the neighborhood and therefore AT&T can only offer the slower DSL speeds. Perhaps you can convince AT&T to install a fiber fed DSLAM near the border of your neighborhood. If there is fiber in the area this can be done without digging up your neighborhood. With current DSL technology (VDSL2) they could offer much higher speeds (up to 100 Mbit down, but more likely 20-40 Mbit). This can be done over your existing neighborhood phone wires as long as the distance to the DSLAM is fairly short. However, your neighborhood still might not be big enough to make a good case. At the very least you would have to get a significant number of your neighbors to commit to buy a high rate DSL service. Are there other nearby neighborhoods that could benefit? That might increase the chances of it happening. I'm not saying that there is a high probability that you can convince AT&T to do this, but you should at least consider all your options.

A lot of people are suggesting faraday cages as the answer. I'm not sure that is really as cheap as people think it would be, and I really don't care if people are using their phones during the pre previews or previews. I'm thinking that a zero tolerance policy along with a phone detector system is a better answer. My guess is that once the lights are out, an HD camera mounted in the ceiling over the audience will easily be able to pick out any light coming from the audience. With a one time simple calibration (putting a light in the end seats of each row and telling the software how many seats are in the row) the software can probably report the exact seat location, or close enough. Then after some threshold, say 30-60 seconds of light, the system could report the theater number and seat location of the light source to theater staff. An usher could then be dispatched to observe the behavior and throw the customer out, or at the very least cause the customer to quickly put their phone away when the usher walks into the theatre.

Yes, that is one of the purposes of a pretrial hearing. The judge has to determine whether or not the case should proceed to a trial or be dismissed. In order for there to be a trial, the Judge has to determine if the party bringing the lawsuit (the federal government in this case) has enough evidence to warrant a trial. The Judge also has to make a preliminary judgement about how likely the party bringing the lawsuit will win. This is needed in order to determine whether any preliminary injunctions should be issued prior to the trial (i.e. an injunction that takes place and stays in force until the trial is completed or another hearing reverses the injunction).

United States Begins Flying Stealth Bombers Over South Korea 567

skade88 writes "The New York Times is reporting that the United States has started flying B-2 stealth bomber runs over South Korea as a show of force to North Korea. The bombers flew 6,500 miles to bomb a South Korean island with mock explosives. Earlier this month the U.S. Military ran mock B-52 bombing runs over the same South Korean island. The U.S. military says it shows that it can execute precision bombing runs at will with little notice needed. The U.S. also reaffirmed their commitment to protecting its allies in the region. The North Koreans have been making threats to turn South Korea into a sea of fire. North Korea has also made threats claiming they will nuke the United States' mainland."

This seems to be a reasonable situation to define limits to what a law abiding person needs for personal use.

Seriously? I hope you are the last one to say it. Reading between the lines of your quote above, it would appear that you think it might be reasonable to outlaw access to this technology, solely because you can't think of a legal use for it.

As others have posted, there are certainly legal usages. I can think of others, but that is besides the point. The whole idea of limiting something because it might be used for illegal purposes is ridiculous.

Regardless of the "legal" ideas proposed, sometimes new technology leads to new ideas, i.e. as storage costs go down and capacities go up, new ways of using storage may evolve. One (possibly half-baked) idea I can think of is crowd sourced, highly redundant, "free" backup storage.

No, the article is quoting aureal density which is expressed in gigabits or terabits per square inch. The problem with the article is that it is combining data from various sources and misreading/misinterpreting the data (so what's new, this is Slashdot after all).

First, the summary above says that Seagate will produce a 60 Tb drive by 2016. That is not true. Seagate has said they will produce a drive with "up to" 60 Tb of capacity (30-60 TB) by the end of the decade. This is based on the theoretical limits of HAMR technology, which are projected to be in the 5-10 Tbits/sq. inch. range. Current 4TB drives are made with platters that have a density of around 650 Gbits/sq. in., so the math works (10Tb/.65Tb is approximately 15x).

The other part of the article is talking about what the maximum density is likely to be over the timeframe from now to 2016 using PMR technology and transitioning to something new like HAMR. PMR technology will top out at about 1Tbit/sq. inch, so anything over that will require something new like HAMR. that underlying article quotes 1.8 Tbit/sq. in in 2016, which may not be out of line with 5-10 Tbit/sq. in. by 2020 as a new technology like HAMR comes online.

The two articles that I am basing the above on are:
Seagate/HAMR article

Officials Use Google Earth To Find Unlicensed Pools 650

Officials in Riverhead, New York are using Google Earth to root out the owners of unlicensed pools. So far they've found 250 illegal pools and collected $75,000 in fines and fees. Of course not everyone thinks that a city should be spending time looking at aerial pictures of backyards. from the article: "Lillie Coney, associate director of the Electronic Privacy Information Center in Washington, DC, said Google Earth was promoted as an aid to curious travelers but has become a tool for cash-hungry local governments. 'The technology is going so far ahead of what people think is possible, and there is too little discussion about community norms,' she said."

Wilder Publication is under fire for putting warning labels on copies of historical US documents, including the Constitution. The label warns "This book is a product of its time and does not reflect the same values as it would if it were written today." From the article: "The disclaimer goes on to tell parents that they 'might wish to discuss with their children how views on race, gender, sexuality, ethnicity, and interpersonal relations have changed since this book was written before allowing them to read this classic work.'"

One good reason why computers can do more work than people is that they never have to stop and answer the phone.
