Comment Libertarians fiddle while Internet is burning (Score 4, Insightful) 270

Libertarian market driven approaches of 'perfectly informed' customers having access to 'flexible supply' are only workable on paper. Sure, it would be nice if we could get there, but meanwhile our situation continuing to deteriorate. Time to abandon this quixotic quest.
 
What we need is "mostly works for most people most of the time", and to get there we need policy with teeth that mandates Net Neutrality. Sure, it won't prevent all abuses, but we only need to prevent worst of them and let the rest play out in courts.

Comment Certify it (Score 2) 128

Without FIPS certification system engineers won't be able to include BoringSSL in US-government facing applications, since doing so will disqualify them from procurement lists. Since US gov't is largest consumer of cryptographic products in the North American market, BoringSSL must certify or stay irrelevant.

Very interesting post, thank you for writing it up.
 
I have a question. Are there guard bands in biological computation (e.g. our brains) ? I was under impression that our cognitive processes (software) are optimized for speed and designed to work with massively parallel but highly unreliable neural hardware.
 
What I am trying to say is that nature performed optimization decided that it is better to be very efficient all the time, and correct some of the time, but also be very good at error checking. While our CPU and OS designers decided that computing devices must be correct all the time, efficient some of the time, and poor at error checking.

Comment Re:Sure, if you ignore resale value (Score 1) 431

If you are attempting being rational, then you need to reevaluate your decision making process. With rational approach, cost of ownership paired to a list of features is all you should consider. Optimizing the curve, you eliminate initial depreciation by buying used, and high repair/maintenance by selling the car before it gets too expensive to maintain. The optimum ends up being 2-8 years old car of any reliable car. Why reliable? First, it impacts resale value at 8 years old. Second, it allows it to make it to 8 years old without incurring major repair costs. You can't get any newer than 2 years, there isn't reliable supply of these, and selling before 8 years old leaves you with too short of an ownership to flatten the depreciation curve.

In closing, you might not want to drive that hypothetical lasts-50-years car in 49th year, but it makes cost of year 1 to year 5 cheaper.

Again, I disagree.

Very few people outright buy the car and use it until junk yard. For people that lease resale value directly impacts their payment, less it worth at the end of leas term higher the monthly payment. For people that finance, trade-in value of their last car impacts their payments. In almost all cases original buyer and second-hand buyer are financially tied via 'cost of ownership' concept.

The car is not a software product, and obsolescence is not clear-cut or binary. Nearly all car features, including safety, are tied to original car budget. For example, luxury 5 year old car will likely still have more safety features than 0 year old econobox. That is, you are A LOT more likely to survive a crash in 2009 Mercedes S500 than 2014 Chevy Spark. I can find many examples of 10 year old cars that are still 'feature-complete' with anything that can be found on the road today. Your "obsolete after 5 years" is way, way off and suggests to me you are trying to rationalize your leasing habit.

If you ever visit automotive junk yard you will see that write-off accidents are minority and mechanical failure is majority of causes that lead cars to end up there.

Mechanical failure could be further categorized to catastrophic failure (e.g. timing belt in interference engine) and multiple minor concurrent issues that exceed replacement value. While I don't have hard data on this, I believe that leading cause of why cars end up in junk yards is transmission failure. Still, most of the cars that make to the junk yard could be made run or are still running.

Therefore, it is safe to conclude that car with higher degree of mechanical reliability, and cars that are cheaper to repair will be used for longer time.

>>> A car that falls apart after 5 years isn't any higher quality than a car that runs for 50 years, if you're going to replace either in 5 years anyway.
 
Faulty thinking. While you might get tired and replace car in 5 years, a car that runs for 50 years will have multiple owners. Its residual value will be higher. Environmental impact of manufacturing and then recycling it will be lessened due to getting spread over many more years.
 
  Car that runs for 50 years is always higher quality that on that falls apart after 5 years no matter how you use it.

Chinese-branded cars make early KIAs look like a paragon of quality. The tradeoff of lack of quality for lower price might be acceptable in consumer goods, but in North American automotive world where baseline costs is dictated by regulations this simply won't work. Add on top of that economic drag off mandatory dealership sales model and you can't really cut the costs and overhead to create cheaper offerings.

As to Chinese-made Volvos - unless they are offering 10 year bumper-to-bumper warranty you will not see many of these of the road.

Submission + - Facebook Is Making Us All Live Inside Emotional 'Filter Bubbles' (vice.com)

Daniel_Stuckey writes: It hopefully doesn't come as a surprise that your friends shape who you are. But we tend to think of that on a micro level: If your close circle of friends tends to have tattoos, wear polo shirts, or say "chill" a lot, it's quite possible that you'll emulate them over time—and they'll emulate you too.

But what happens on a macro scale, when your friend circle doesn't just include the dozen people you actually hang out with regularly, but also the hundreds or thousands of acquaintances you have online? All of those feeds may seem filled with frivolities from random people (and they are!) but that steady stream of life updates—photos, rants, slang—are probably shaping you more than you think.

A massive Facebook study recently published in PNAS found solid evidence of so-called emotional contagion—emotional states spreading socially, like a virus made of emoji—on the social network.

Submission + - Chinese-Built Cars Are Coming To The U.S. Next Year

cartechboy writes: "Made In China." It's a sticker we all know too well here in the U.S., and yet, it seems not everything we buy is made in China. To date, there haven't been Chinese-built cars in the U.S., but we keep hearing they are coming. Now it seems it's about to become a reality, as Chinese-built Volvos will be arriving in the U.S. as early as 2015. The first model to arrive will be the S60L. The payoff for Volvo if it manages to convince buyers that its cars built in China are just as good as those currently built in Europe is vast. Not only will it save on production costs, but it will help buffer against exchange rate fluctuations. Volvo's planning to make China a manufacturing hub, and that makes sense since it's now owned by Chinese parent company Geely. But will Chinese-built cars be just as good as European-built cars, and will consumers be able to tell the difference?

Submission + - Wikipedia creates new rules, forcing editors to disclose if they're paid (arstechnica.com)

mpicpp writes: The Wikimedia Foundation, a nonprofit which operates Wikipedia and related projects, explained yesterday that it will establish new rules covering paid editing.

The heart of the change is that anyone who is paid to edit the site must "add your affiliation to your edit summary, user page, or talk page, to fairly disclose your perspective," according to Wikimedia's explanation of the change. The organization has also published an FAQ on paid editing.

The changes come after some high-profile commotions over paid editing. In October, Wikipedia deleted more than 250 accounts believed to be connected to a PR firm that was writing articles on the site. In January, the Wikimedia Foundation fired an employee who was accused of taking paid editing gigs.

Submission + - Google confirms indie musicians must join streaming service or be removed

Sockatume writes: In a statement to the Financial Times and reported by the BBC, Google has confirmed that it will remove the music videos of independent artists unless they sign up to its upcoming subscription music service. Many independent musicians and labels have refused to do so, claiming that the contracts offer significantly worse deals than the likes of Spotify and Pandora, and that Google is unwilling to negotiate on the rates it offers artists. A Google spokesperson indicated that the company could start removing videos within days.
