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

multimediavt Re:Can I go anywhere useful yet? (117 comments)

Battery swaps might make this even less of an issue (a two minute pit stop rather than a thirty minute pit stop), but I'm a bit more skeptical about the practicality of those.

Why?! We do it with propane tanks now and doing it with EV batteries makes MUCH more sense. Only problem is getting everyone to agree on a standard size/configuration to make the stations just like gas stations, minus the pumps.

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

multimediavt Re:This doesn't seem very extreme. (117 comments)

While perhaps to be taken with a pinch of salt - http://www.teslamotors.com/en_... - with the larger battery - at 65MPH claims to get 261 miles. To get a Tesla to 350 miles needs an extra 30kWh of battery - about 120kg at the same performance as the existing battery. This will easily fit in the trunk.

Better yet, pull the seats and anything else you don't need out of the car and try. The big battery gets 306 miles (492km) out of a 4600+ lb vehicle so getting an extra 8km isn't going to be that hard, even if it was 80km I think it could be done without modifying the production car much at all. This "record" is laughable. The only reason Tesla doesn't have it is that they don't care about non-practical applications of electric vehicles, it would seem. Elon has a rocket company for going farther, faster.

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

multimediavt Re:Getting there. (117 comments)

However with my current car I get about 450 miles per tank. at 66mph.

Now the issue is some times I need to drive for 8-10 hours. So I will need to fuel up mid way. The charge time for electric may still be an issue.

Remember this was kilometers, so you get 724km per tank. That's almost 50% more than the electric, one seater, made of tissue paper (euphemism, but not far off compared to a real road car) and riding on tires barely bigger than that for a children's bicycle.

As a comparison, the Tesla Model S weighs more than two tons (US or Metric) and gets 306 miles per charge (492 km). I am not impressed by this "record".

Mathematicians Use Mossberg 500 Pump-Action Shotgun To Calculate Pi

multimediavt Re:What would a real nerd do? (311 comments)

Actually, if you were a nerd like me you'd have memorized Pi out to at least 25 decimal places as a child. 3.14159265358979323846264338. It was in the back of my Geometry book as a freshman in high school. Geometry class was so boring I memorized Pi one day in class from the value in the glossary of the textbook that carried out 26 decimal places.

Aereo To SCOTUS: Shut Us Down and You Shut Down Cloud Storage

multimediavt Re:Question about rebroadcasting (342 comments)

Suppose I rent an apartment in New York, and I setup an antenna to pick-up New York broadcasts. Then I stream those broadcasts to my TV at home. Have I illegally retransmitted the signal and I need to pay a licensing fee?

This is basically what the whole case is about. The decision will answer your question.

Aereo To SCOTUS: Shut Us Down and You Shut Down Cloud Storage

multimediavt Re:How many? (342 comments)

Does Aereo remove the advertisements those broadcasters placed into the stream? If not then how are they taking away a source of revenue?

They wouldn't have to. Because the ad rates are different based on delivery medium (newspaper, magazine, broadcast tv, radio, Internet) the broadcasters in this case could argue successfully that they are losing revenue because these Aereo streams would not get counted in their ad "impressions" for broadcast tv and therefore not be charged off at the higher broadcast rate, or even not at all. Since broadcast tv exists on ad revenues they could win that point, but the issue could be worked around by kicking back to the broadcasters based on stream/antenna numbers. That would get passed onto the consumer like Netflix's price hike due to bandwidth extortion by the ISPs, so if Aereo loses this point they could flounder. I will be watching this case closely as the outcomes affect some of my projects in the works. If Aereo loses this case it will be a long time before the broadcasters' cabal comes down, especially with the courts still backing the content providers and politicians are on the take even more with recent SCOTUS decisions.

In a Hole, Golf Courses Experiment With 15-inch Holes

multimediavt Re:Stop people from quitting (405 comments)

experimenting with 15 inch golf holes the size of pizzas to stop people from quitting the game.

Why not make the entire green the hole? People would never be able to quit.

Spoken like someone who has never played golf. Even making the whole green the target/objective, it may still take most novices three to five strokes to get to the green, let alone land on it. It's why the 15" hole suggestion is laughable. Putting is only a part of the game that adds to your score, and it's typically not the hardest part to master, either.

In a Hole, Golf Courses Experiment With 15-inch Holes

multimediavt Re:Softball (405 comments)

I have a similar post farther down the thread but wanted to touch on something you said. The rules of golf (as is) can still apply in your suggested model. They are very adaptable to different course types as well as the differences in stroke and match play. I agree, more par-3 courses with less challenging designs would be the way to get more people golfing. I have seen this happen in small communities where a par-3 goes in. A larger demographic will frequent these courses because they can afford to play more often and they can work on their skills (especially short game). More inexpensive par-3s and finding ways to reduce equipment and greens fees would also help. I don't think it needs different rules nor a different name. It's still golf. Let's not start making different rules for different people or places, like American football and baseball. Golf is golf no matter who plays or where. The rules don't change and that adds integrity to the game at all levels.

In a Hole, Golf Courses Experiment With 15-inch Holes

multimediavt Curtis has it dead on (405 comments)

Curtis Strange's quote is spot on. It's all a bunch of talk. There's no way the USGA nor the R&A would approve such a thing. Not only is putting just one aspect of the game, making the hole bigger won't make you better. Anyone that's played the game long enough to want to get better knows you putt at smaller objects to improve your putting, not larger objects. As I said, putting is also one of many aspects of the game. Driving, approach, chipping and pitching are all equally important as they add strokes to your game the same way putting does. I would argue that getting to the green is not only more difficult than putting once you're there, but requires more physical ability and mental challenge than putting. To have the swing consistency to hit every fairway and every green in regulation is more difficult to develop than reading a green and striking a putt. I have been golfing since I was 17 and still struggle with swing issues 25 years later. I can putt like a fiend, though. Sure, I know the "putt for dough, drive for show" saying, but every stroke counts. You can one and two putt all day, but if you can't get it to the green in three or less, your putting can only save so much. So, no, I really hope nothing comes of this bigger hole thing. It's counterproductive to their advertised ends, helping improve the game. What's next, a field width goal twenty feet high so more people will be better at football/soccer so they will be attracted to the game? I really don't like rule changes to appease people who want to apply less skill and practice to a game so they can compete with more skilled and practiced players. I thought that's what the handicap system in golf was for? We already give people 20+ strokes per round based on their lesser skills, why would they need anything else in a game where the lowest score wins? Bigger hole = dumb idea

How much do you spend yearly on mobile apps?

multimediavt Re:WOWZA! (240 comments)

You are the one who doesn't understand how money is made with open source software, or even most closed source software for that matter.

You seem fixated on the mistaken notion that paying for software is what drives the business, open or closed. it does not.

And you don't seem to understand how truly rare successful, not-for-profit software is. I have been involved with software start-up companies since 1994. If there is no money to be made its chances for success are slim to none. Sure, there are some labors of love that have lasted for years, but their usage and continued existence are limited. Of all the projects you can name, or even Google, there are thousands for each one that have failed or been abandoned. Money is made on open source software the same as any other, supply and demand. If there's no charge for the software then something related must be monetized, e.g., support, upgrades, etc. in order for supply to keep up with demand. Red Hat monetizes both support and upgrades (RHEL) for its Linux distros. Google monetizes data about their customers to sell ads. Two of the most successful open source companies anybody can name. Labors of love can monetize by donation, but that's usually the same as monetizing upgrades should donation lead to continued suppression of any nagware feature going forward through successive versioning of the application. How many labor of love projects are used by more than a niche in the world of users? I guess if you have limited metrics of success any labor of love project is a crowning achievement. Bound in a nutshell and master of infinite space and all, but to speak as if all open source software is developed intentionally for free and only for the enjoyment of the developers is beyond naive of how the world works. Sure open source software has helped a lot of people make their own money and not a lot has been given back to some of those developers, but if all software was open source there'd be a lot less people interested in developing it. Which is why so few people actually develop open source software, because they need to pay the bills. I did not say that paying for software drives a business. If there's no commerce (an exchange of goods or services for a fee, goods or services) there really isn't business, is there? If you develop a piece of software and just put it out there you're not doing business. Business requires an exchange. If all I do is download your software I am not doing business with you. If I send you an email about a bug and you fix it, I am still not doing business with you. If you don't see how giving software away is disruptive to the actual monetized software business then you and the rest of the masters of infinite space that mod you up are truly lost because you don't even understand what you're doing. This was a stupid poll. I should really stop coming here for this stuff. You probably haven't read the new Dice terms for this site! Amateurs!

This 1981 BYTE Magazine Cover Explains Why We're So Bad At Tech Predictions

multimediavt Re: instant access to computers around the world (276 comments)

Quite. Its amazing how many people today still think the internet = the web. Mention stuff like ftp, gopher, archie or WAIS and you just get blank looks.

Bah! They glaze over at telephone modem. They would think a BBS was an early Facebook. Of course, they'd be right, but Zuck probably doesn't know about the BBS days, either.

This 1981 BYTE Magazine Cover Explains Why We're So Bad At Tech Predictions

multimediavt Re: instant access to computers around the world (276 comments)

instant access to computers around the world

Actually, in 1981 the internet existed, you could FTP and use email, as long as you knew the bang path routing.

It wasn't for 2 more years after 1981 that I learned of it, but I knew people that were using it in the late 70's even. Contrary to what seems to be the popular public belief, the internet didn't start in the 1990's. That's just when the masses became aware of it, largely due to the influx of AOLers.

Granted it was much smaller then as far as number of connected machines.

Well, it was also a DARPA (ARPnet) project back then and only participating universities, govt contractors and govt agencies could get on. It was not publicly available. What was publicly available then was modem Bulletin Board Systems (BBSs). Those had chat forums, localized email and file sharing. If you were lucky and "knew a guy" or a guy who knew a guy, you could get on a networked BBS that exchanged files with other boards around the world via nightly sync or even luckier if you had someone from one of those universities or other running a board that also bridged to ARPAnet. That's where a lot of old usenet content got started. Those were the good ole days of social media. BBS meet and greets were fun. A lot less scary than now, fore sure and for a lot of new and different reasons.

FTFA:

"it's also a smart visual explanation of why the future of technology so often bears so little resemblance to anyone's predictions"

No, it's not an explanation at all. It was intended as a metaphor for miniaturization of electronics. Noone in their right mind would take a full QWERTY keyboard with keys the size of pin heads literally.

Mathematicians Use Mossberg 500 Pump-Action Shotgun To Calculate Pi

multimediavt Re:What would a real nerd do? (311 comments)

A real nerd would know how to calculate Pi from scratch, no shotgun required...

Pi = (4/1) - (4/3) + (4/5) - (4/7) + (4/9) - (4/11) + (4/13) - (4/15) ... (keep going until you get the number of decimal places you need.)

Gaaaa! What? How about 22 / 7 . Way closer, less painful. Nerds do it more efficiently and more accurately. That was about as bad as the shotgun method, maybe worse. I stopped doing the math at (4/15) when the result was 3.01[something] and adding (4/17) was 3.25[something] ... Not even close.

Not only are they Canadian, they're French Canadian. Calling them American is worse than calling them Canadian as the Québecers would rather be their own country all together. I just think they're smoking something to not use simple long division to calculate Pi, especially as a university research mathematician. I mean, really! 22 / 7 = closer to Pi than their stupid shotgun embarrassment.

":...being a mathematician, they turn to you." You're not much of a mathematician if you don't already know the value of Pi out to several decimal places without the need to expel valuable ammo in an experiment. /john

Yeah, and how hard is it to divide 22 by 7 with a twig in the dirt, "Mr. Mathematician"? That's also an acceptable approximation of Pi that is 4.0249943477E-2 percent off the "true value". I think the colder climate and/or recreational hallucinogens has slowed those Canadians' brains a might. Maybe that's the way to avoid zombies, after all.

How much do you spend yearly on mobile apps?

multimediavt Re:WOWZA! (240 comments)

you have some bad misconceptions between your ears, advocating and using open source has nothing at all to do with whether or not a person is pro or anti capitalism. Plenty of money to be made in open source, that's how I make my living. I run quality free apps on my phone, I pay the phone provider for the platform and connectivity to do so. Capitalism all around, good stuff.

Meanwhile, Microsoft and some other closed sourced companies have governmet in its pockets to sway things their way, that is not capitalism.

No, not at all really, having been an avid reader and commenter for more than 15 years I can say that this crowd (as a majority that comments in these threads dealing with mobile apps) may be for making money but certainly not spending it on the work of other people. Have you read the comments in this thread? The clear consensus is that this crowd doesn't spend money on applications that they use. I hate to tell you this but capitalism requires consumer spending to work. You can't make money if no one gives you money for your work. And I love the little libertarian bullshit dig at big business and the government at the end to get mod points from that crowd. Show me one profitable open source company that isn't lobbying the government? Google is in the same boat as Microsoft and Red Hat for that matter when it comes to trying to have ignorant or corrupt government officials in their pockets. Don't be naive and think that I am so. You may want to do your own research rather than parroting and pandering like former ignorant and corrupt politicians. Plus, one of the reasons behind open source software development was to disrupt capitalism in the software industry. What do you think the effect is when your competition is giving its product away? No, definitely no misconceptions here. Your definition of capitalism and your understanding of economics just don't jive. You have a misconception in that the money you spend for a phone and cell service somehow makes its way to the app developers and capitalism all around. Not so much really.

Ask Slashdot: How Do You Manage Your Personal Data?

multimediavt multimediavt writes  |  more than 2 years ago

multimediavt writes "Ok, here's my problem. I have A LOT of personal data!

And, no, it's not pr0n, warez, or anything the MPAA or RIAA would be concerned about.

I am realizing that I need to keep at least one spare drive the same size as my largest drive around in case of failure, or the need to reformat a drive due to corrupt file system issues. In my particular case I have a few external drives ranging in size from 200 GB to 2 TB (none with any more than 15 available), and the 2 TB drive is giving me fits at the moment so I need to move the data off and reformat the drive to see if it's just a file system issue or a component issue. I don't have 1.6 TB of free space anywhere and came to the above realization that an empty spare drive the size of my largest drive was needed. If I had a RAID I would have the same needs should a drive fail for some reason and the file system needed rebuilding. I am hitting a wall, and I am guessing that I am not the only one reaching this conclusion. This is my personal data and it is starting to become unbelievably unruly to deal with as far as data integrity and security are concerned. This problem is only going to get worse, and I'm sorry "The Cloud" is not an acceptable nor practical solution.

Tape for an individual as a backup mechanism is economically not feasible. Blu-ray Disc only holds 50 GB at best case and takes forever to backup any large amount of data, along with a great deal of human intervention in the process. So, as an individual with a large data collection and not a large budget, what do you see as options for now (other than keeping a spare blank drive around), and what do you see down the road that might help us deal with issues like this?"

Can SSD Electronics Be Replaced & Retain Data?

multimediavt multimediavt writes  |  more than 2 years ago

multimediavt (965608) writes "I know that because of the delicate calibration between electronics and read/write heads in standard hard drives, that even with matching electronics it is next to impossible for those not fortunate enough to work for a data recovery lab to retain the data stored on the platters after replacing the onboard controller electronics should they fail. I am curious if that is true of SSD drives as well? I would assume not, but wondered if any /. folks had any insight on whether this was true or not? Beyond the speed increases and not having to worry about head crashes due to traumatic, sudden deceleration, the ability to replace faulty controller electronics (or even to upgrade them down the road) would be yet another huge advantage of the technology."

Apple: Consumer Reports Antenna Testing Flawed

multimediavt multimediavt writes  |  about 4 years ago

multimediavt (965608) writes "Many seem to be jumping down Apple's throat about the iPhone 4 antenna issue, but there still has not been any independent, credible, scientific diagnosis of the problem. Bob Egan, an electrical engineer, has posted a blog explaining how Consumer Report's testing was flawed and simply reinforces anecdotal evidence of a problem, but does not give any credible scientific diagnosis as to the cause.

From TFA:

"Consumer reports '½ÂoeRF'½Â engineers should know better than to think they can run an engineering grade test for an issue like this in a shielded room. And certainly not one with people in it.

To even reasonably run a scientific test, the iPhone should have been sitting on a non-metallic pedestal inside an anechoic chamber. The base station simulator should have been also sitting outside the chamber and had a calibrated antenna plumbed to it from inside the chamber."

Ok, there's a problem, but let's not overreact until we know the real cause and how it can be fixed. A recall may be needed, but it could really be a simple software fix."
