Fooling a Mercedes Into Autonomous Driving With a Soda Can

timeOday Re:Boo (84 comments)

It is better to err on the side of over-inflation. The centrifugal forces of high-speed driving are pretty extreme (even 100 mph) and you'd have to over-inflate a LOT to replicate them, so they'll take a lot before bursting from pressure alone. The problem with under-inflation is the tire is racked by vibrations that cause extreme forces, and also cause it to overheat.

Here is a cool page, evidently 225 mph at 20 psi below the optimum is a bad idea.

Getting Back To Coding

timeOday Re:Less coding, more assembling pieces (140 comments)

No the trend actually is the same in application development - away from clean sheets, and towards lashing together complex components that can made to sort of work together, supported by complex development tools.

It sucks, but I'm intentionally throwing more of my time now into learning the latest languages and development environments. Are they better? Not really. But you will never, ever convince anybody that fuddy-duddy is actually cool. They'll just think you're irrelevant. Every career has some drawbacks, and spending your life chasing fads, coupled with others' disdain for everything you did or learned over a decade ago, is a drawback of this one. (Heck, why didn't you start a successful startup or at least move into management by now, anyways?)

Fooling a Mercedes Into Autonomous Driving With a Soda Can

timeOday Boo (84 comments)

Cars are generally not designed to be resistant to 'hacking' by their owner/operators, and should not be. Yes, you can drive without a seatbelt if you snip the little blue wire. You can disconnect your airbags. You can cause your tires to explode just by letting out most of the air and driving on the freeway.

Presenting this as some sort of coup fosters the notion that he system ought to be idiot-proof. No sudo rm -fR / for you! We'll put a thousand annoying and ultimately useless obstacles in the way to doing any little thing!

Don't blame the car for not protecting itself from you.

Nevada Construction Project Could Be Tesla/Panasonic Gigafactory

timeOday Re:And it's already closed (81 comments)

Does nobody remember this headline from a few months ago? Tesla could start on Gigafactory in 2 states, then cut 1:

"We are going to proceed with at least two locations in parallel, just in case one of them encounters some issues after breaking ground," Musk said. He said Panasonic was likely to be Tesla's partner in battery production.

The fact that construction started and then stopped makes it sound more like this is that - who else would do such a thing?

Nevada Construction Project Could Be Tesla/Panasonic Gigafactory

timeOday Headline trifecta (81 comments)

I was going to write something snarky about the silliness of getting excited about this one factory, of all things. But it really does hit all the right points, doesn't it: (1) the manufacturing industry in the US, (2) the geopolitics of our oil addiction and resulting involvement in the middle east, and (3) environmental harm from fossil fuels.

Morgan Stanley is excited about the potential use of gigafactory batteries for home energy storage and grid independence, and thinks they might make more on that than on cars. (I would have thought good old lead acid car batteries were cheaper for this?)

Grad Student Rigs Cheap Alternative To $1,000 Air Purifiers In Smoggy China

timeOday Re:What the hell? (170 comments)

You could just leave your vacuum cleaner running I guess... (even Shop Vacs have HEPA filters available, and they move a lot of air!)

But it makes more sense to filter the air at the inlet if you can, or at least as it recirculates through the HVAC system already built into your home. Check your air filter once in a while, people!

Is the App Store Broken?

timeOday Re:Decaying ratings (241 comments)

What you are missing is that ratings are assigned relative to the competition that existed when the rating was assigned. Go over to gamespot and check out the graphics of a game that got the top rating for graphics 8 years ago. Are those graphics still 10/10? Not even close. Go over to Amazon.com and search SD Cards by "Average Customer Review." Many of the top-ranked cards are little 8 and 16 GB cards that were rated up years ago.

Is the App Store Broken?

timeOday Re:It's not a marketplace.. (241 comments)

There are various "dreams" of course, but the Gold Rush mentality has always been strong in US culture. Our current top marginal tax rates certainly support that assertion - average people pay dearly in real money to protect their fantasy future-self.

Is the App Store Broken?

timeOday Re:It's not a marketplace.. (241 comments)

Any marketplace of infinitely scalable production is a lottery!

Before music recordings, if you wanted to hear music, somebody had to play it. A more popular musician could make somewhat more than an average musician - maybe substantially more - but the top handful couldn't entertain the entire planet singlehandedly. Now they can. The economy of agrarian farmers - where a 20% more productive farmer makes 20% more money - is over. Now it's winner-takes-all.

An Accidental Wikipedia Hoax

timeOday Re:A cautionary tale? (179 comments)

I liked your post right up to the last sentence when you said the real problem is our tendency to not check everything. That is simply not possible. Life rolls forward on a vast number of assumptions every moment, and most of them are correct, or good enough to get by on. (False assumptions that don't matter and cannot be observed - like this Amelia Bedelia thing - can linger indefinitely).

Tesla and Panasonic Have Reached an Agreement On the Gigafactory

timeOday Re:What makes this a gigafactory? (94 comments)

Which part do you find suspect? Tesla wants to make a major launch of a $35K all-electric car, which will require a huge number of batteries, above and beyond the current supply. The word "allegation" sounds as if you think the new Telsa model won't use batteries? Or that there's already enough production to support the new Tesla model, presumably going straight into a huge hole in the ground? Or what?

Oracle Offers Custom Intel Chips and Unanticipated Costs

timeOday So, what does the in-memory database option do? (96 comments)

This being slashdot, it would be nice to have the article on "gotcha" licensing accompanied by at least as much information what it actually is, and when it would be worth paying for. (And not just some snarky comments about how cheaper databases already have in-memory tables, unless that's really all it is!)

Suddenly Visible: Illicit Drugs As Part of Silicon Valley Culture

timeOday Re:My experience with hydrocodone... (507 comments)

I am a bit unusual in NOT having started drinking coffee until almost the age of 40, and had the same experience of hyper-concentration the first time! Now I can hardly feel anything, if at all.

I think growing tolerance to drugs is practically universal. I've known several people who started Prozac etc. and told me, "wow, so THIS is what I've been missing! Life is so great!" But fast forward a year, and they don't seem that much happier. Yet they still have a costly prescription for the rest of their lives.

Verizon Now Throttling Top 'Unlimited' Subscribers On 4G LTE

timeOday Re:1 or 1 million (271 comments)

Sigh, I must be on slashdot. "Unlimited" doesn't mean "free from the laws of physics." It means it isn't limited by the carrier. (If I told you there was no speed limit on the autobahn, would you honestly think I was hoping to drive faster-than-light?)

Google Looking To Define a Healthy Human

timeOday Re:The finding (125 comments)

Oh boy, brace yourself for thousands more comments like this objecting to the idea that there is one single "ideal human" and finding 'his' exact DNA sequence, even though nobody has stated such intent and there is no reason to do it.

Long-range Electric Car World Speed Record Broken By Australian Students

timeOday Re:Range is not the issue. Cost is. (120 comments)

From the Tesla Motors website: "As we at Tesla reach for our goal of producing a mass market electric car in approximately three years, we have an opportunity to leverage our projected demand for lithium ion batteries to reduce their cost faster than previously thought possible.... By the end of the first year of volume production of our mass market vehicle, we expect the Gigafactory will have driven down the per kWh cost of our battery pack by more than 30 percent."

timeOday Re:Range is not the issue. Cost is. (120 comments)

Surely you have heard of the Tesla Gigafactory? It is a $5BN investment that does nothing but address your exact concern. It doesn't address range. It doesn't address recharge time. It addresses COST.

Amazon's Ambitious Bets Pile Up, and Its Losses Swell

timeOday Re:23% revenue growth! (168 comments)

I would like to understand this. The article says that losses for the next quarter are expected to be larger: "Mr. Szkutak listed some of the reasons: Amazon Web Services is in a price-cutting war with Google and others. Six new warehouses have opened. And the company will spend $100 million on new content to put on those phones and Kindles."

The warehouses, at least, are quintessential infrastructure investment. You are saying Szkutak is incorrect in asserting they cut into short-term profits?

Amazon's Ambitious Bets Pile Up, and Its Losses Swell

timeOday 23% revenue growth! (168 comments)

Amazon's revenue grew 23% over the same quarter last year. If the company were not growing AND not profiting, that would be bad. But as large as Amazon's revenues now are, to still be growing that fast is very impressive, and proves they could start taking profits at any moment simply by pocketing more revenue instead of re-investing.

Bill Nye "The Science Guy": Creationism Is Not Appropriate For Children

timeOday timeOday writes  |  about 2 years ago

timeOday (582209) writes "BigThink has released a video missive by Bill Nye "The Science Guy" in which he challenges the low level of acceptance of evolution, particularly in the United States. He does not mince words: 'I say to the grownups, if you want to deny evolution and live in your world, in your world that's completely inconsistent with everything we observe in the universe, that's fine, but don't make your kids do it because we need them. We need scientifically literate voters and taxpayers for the future. We need people that can — we need engineers that can build stuff, solve problems.'"

Nintendo Favors Europe Due to Weak US Dollar

timeOday timeOday writes  |  more than 6 years ago

timeOday (582209) writes "The LA Times is reporting that the new Nintendo Wii Fit is hard to find on US shelves, due not only to strong demand but also the United State's declining status in the world economy: "[Nintendo] is also is shrewdly maximizing its profit by sending four times as many units to Europe, reaping the benefits of the strong euro," says Michael Pachter, an analyst with Wedbush Morgan Securities. "The shortage demonstrates one consequence of the weak dollar. We're seeing companies ignore their largest market simply because they can make a greater profit elsewhere.""

timeOday (582209) writes "Looks like somebody just blew a chance to inaugurate the 200-mile-high club. Lisa Nowak, a mission specialist aboard the space shuttle Discovery in July, was arrested Monday on charges of battery and attempted kidnapping after allegedly trying to subdue a romantic rival with pepper spray and abduct her from a parking lot at Orlando International Airport. It seems both women were chasing astronaut Bill Oefelein, a Navy commander. Police have recommended Nowak be held without bond."

timeOday (582209) writes "The U.S. National Science Foundation (NSF) asks, "Where has the Money Gone? Declining Industrial Support of Academic R&D." Since 1999, inflation-adjusted corporate support for U.S. academic research has plummeted by one third. Prominent members of industry and academia have indicated disagreements over the handling of intellectual property (IP) are partly to blame, driving U.S. corporations overseas in search of more favorable licensing terms. Will this lead to a scientific decline in the U.S., or is reduced industry influence over scientific research a good thing?"
