but any other area where the experience is worse than stock android of the equivalent version just seems weird.

Where do you think Samsung and LG stick all the junior devs and QAs? And then pull them off the moment they start making better design choices, to go work on more lucrative projects? Yep, the shitphones. The only choice with the bottom of the barrel phones is to go directly to stock android (which is pretty easy if you have an hour or so to kill and can follow basic instructions) so for Bennett to spend so much time wondering out loud why cheap phones are cheap is the weird part. How about an article on the cheapest phone you can turn into an AOSP/Cyanogen handset with good results? Nah, why bother; that would't start a flamewar!

I'm not sure. It was at 32000 feet when they last had contact, which means it wasn't quite at cruising altitude, but it was still several miles up. The 777's cruising speed is mach .84, about 630 MPH. I'm not going to do the math (i'd love it if one of you aerospace guys would, especially since we know where it landed and the last known altitude and the great circle between Schipol and Kuala Lumpur), but I think it would be safe to say that on the ascent it would be going about 350-450 MPH. I can't see terrorists getting their hands on that kind of hardware. Both Ukraine and Russia on the other hand...

FWIW the last flighttrack data showed a speed of 490 kts (564mph), altitude of 33,000 feet (a common cruising alt if there is turbulence at 35k+) Lat 48.088 Lon 38.6359.

How about they actually solve a murder, rape, or kidnapping once in a while? 35% of murders don't get solved

The second sentence contradicts the first. They do solve murders quite often; 65% of the time in fact.

Its actually more nuanced, only 2/3rd (65%) of all murder cases nationally see a single *arrest* which is to say that they have a decent suspect in mind. Not every arrest turns into a conviction, naturally, so the actual "solved" rate is much lower, below 50% for a lot of places. Here's a recent stat to help you plan your next murder: "In 2008, police solved 35 percent of the homicides in Chicago, 22 percent in New Orleans and 21 percent in Detroit. Yet authorities solved 75 percent of the killings in Philadelphia, 92 percent in Denver and 94 percent in San Diego." As you might expect, areas with lower murder rates overall saw a higher solve rate.

Plus, it really eliminates the need to own so many cars. The car can do multiple duty, and borrowing a car is much more practical when it can pick you up at your door (whether it is shared between neighbors or is actually a taxi).

Parking becomes much easier to optimize when cars can drop and pick people up anywhere, and park themselves. There is no need for parking locations to be within a short walk of every destination.

You can also split up cargo vs personnel transport. Passenger vehicles could be smaller and optimized for passengers, with cargo vehicles being big boxes on wheels. You could take a bus to the grocery store and send your 12 bags home in a cargo vehicle while you take a bus back, or a 1-person car, etc. People don't need to own a vehicle large enough to make that trip they make once a month - they can rent for that.

Endless possibilities for transportation when you don't need people in the loop.

You hit on the solution to the very problem. To operate in passenger-less mode simply require that the car be reciving destination instructions from an approved souce (such as some big, audit-able company) who would be a fair bit less likely to greenlight rolling-bomb commands on their cars.

As rooftop solar gets cheaper every year, electricity won't be the biggest environmental impact of lighting.

I already have a number of friends who's rooftop solar panels generate more electricity than they use. Once people reach that point, the biggest impact to the environment will be manufacturing --- either with poisons like mercury in CFL bulbs or with dirty semiconductor fabs and lead on circuit boards for LEDs.

Hard to beat a plain glass globe with a metal wire for clean recyclable environmentally friendly materials.

Don't forget that the solar panels only over-produce for the household at times when they *don't need lights*. This impacts your environmental summarization because in order to shift that electricity from solar hours (when the sun is up) to non-solar hours (when the sun is down and you need more indoor lighting) you need to use additional expensive (economic and environmental) techniques like battery storage or borrowing electricity from a nearby coal fired plant.

I have a few dimmable Cree bulbs and they flicker. Not impressed. Supposedly Phillips make better dimmable bulbs.

I just tested the two and had the exact opposite experience (with a pretty nice leviton digital dimmer, too). The 9.5w/60w equiv Cree bulbs worked fantastic, no flicker at any light level. The Philips bulbs (10.5w/60w equiv dimmable, according to the package) flickered like crazy and wouldnt even turn off all the way, they just slowed to a 1Hz flicker.

THis is basic statistics learned by every doctor in medical school. specificity and sensitivity, prevalence, pretest and post test probability and false positive/true negative, false negative/true positive. They all factor in to deciding to use a medical test. Every person who comes in and demands a test ussually gets a lecture on this (at least from me) (at work have to post as AC)

Statistics aside there are two more pressing questions: 1, are patients with MCI more likely to convert (10% or greater) in subsequent years? 2, is there a preventative process that can be used by those that test positive, that is safe for the general population? In other words, do we get to narrow our treatment focus with these results, even a little bit? We can piss and moan about statistics but at the end of the day, who really gives a fuck if you were right about the onset of someone's dementia, unless you can do something about it?

I can see a few issues with this.

1. Increase of cost. Adding a pole for the near side would add cost.

At least here in Sweden we have poles on both sides as people will be crossing the street in both directions. Yours work differently?

In the US the poles are installed at/past the sidewalk line opposite the roadway, in other words when you are standing to cross you cannot see the pole on your side because it is behind you. So, either you would have to get people to stand behind the pole, or have them turn around and look at the number before crossing (taking attention away from watching turning traffic, which a pedestrian must be very careful for).

Email requires bandwidth, and you can't distribute it through a CDN like you can with downloads. It's cheap for spammers because they anonymize their email, but security notifications say they come from microsoft.com. Now consider that you have BILLIONS of emails to send. That can get costly.

Why can't you distribute it via a CDN, exactly? I mean someone like Microsoft has either direct control over, or actually runs their own CDN servers: firing up a SMTP service (to route mail based on proximity to destination MX) should be the easy part.

My point was merely that Alexander's CV has very little on it that isn't either irrelevant to his potential customers (at least I hope our financial sector isn't looking for armored warfare expertise...) or closely connected to a series of fed jobs that just keep getting more heavily classified as time goes on.

Hmm let's see if you can pick out the spot where he would be versed only in armored warfare expertise or looking at secret documents all day (this is his CV for the past 15 years):
Director of the National Security Agency (DIRNSA)
Chief of the Central Security Service (CHCSS)
Commander of the United States Cyber Command
Commanding General of the U.S. Army Intelligence and Security Command
Director of Intelligence (J-2), United States Central Command
Deputy Director for Intelligence (J-2) for the Joint Chiefs of Staff
Head of the Army Intelligence and Security Command

Do you think it's possible, after working (ostensibly successfully) as the head of so many organizations, that he knows nothing about management, leadership, best practices, and nonclassified security methodologies (of which there are many)? Do you honestly think he spent 10 years, as the head of these orgs, pushing top secret papers across his desk instead of having his underlings take care of all of that? Come on. Furthermore, I think a lot of commentators on this thread have a complete misunderstanding of what a high-level consulting firm does. Hint, it has nothing to do with configuring firewalls and antivirus apps. Big multinationals will gladly pay $1M for advice as simple as "choose off the shelf security package A, instead of B" as long as it comes from someone whose credentials are beyond repute. He doesn't have to say anything about top secret operations, techniques, or sources, he just has to put his name behind something.
