The logs in the previous test show that the speed was, for the most part, perfectly reasonable, yet projected range fell at 10% faster than should be expected.
They also showed a huge loss in projected range when the car was stopped.
But wouldn't the car be going slower than indicated if it had smaller tyres? Unless these logs were based on a separate wheel speed sensor, that was calibrated assuming larger wheel diameter but that seems unlikely given that the car is computer controlled and must have logging built in.
Clearly, Mr Musk's over the top reaction leads one to believe that he is hiding something.
I wouldn't read too much into this. It seems that he's something of a nerd who takes criticism rather too personally. If you read Slashdot comments, you'll see this personality type is not that rare.
I do agree that the mysterious range level drop overnight is a little suspicious.
I think it's because they're just televisions with some of the electronics removed. You can get higher resolutions but there aren't the same economies of scale so the price jump is huge.
Although the fact that a normal car has the capability to long distances should the occasional need arise does add quite a bit of value to the car. Hiring a car or using public transport for those occasional jaunts cost money and is less convenient.
So, let me get this right... If I put a winnie the pooh sticker on my laptop and claim it belongs to my kid, copyright law doesn't apply to me. CSS takes as much time and effort to produce and is as directly profitable as movies, and that there aren't other ways to access the pirate bay.
Is it a slow news day? Honestly this just seems like an attempt to dig up new dirt on the media cartels. And it comes across as pretty desperate.
Personally, I think a numerical indication works quite well if the system doesn't know how much there is to do. It indicates progress and provides information the user might have even if the computer doesn't. For example, I know an mp3 will typically be between 3MB and 10MB depending on length of the song.
I imagine most Lexus owners would be intrigued if I showed up in a Breckland Beira V8 or a Farbio GTS even though most people don't know of them.
It doesn't need to be recognised. It looks expensive, and the fact that you won something that other people haven;t even heard of is itself a status symbol.
If I didn't have OpenOffice, I probably wouldn't have paid for Word. At least not the latest version. I'd possibly find an ancient version, or find a cheaper rival. Maybe even gone for Wordpad. I don't need anything that has functionality much more complex than font styling, and possibly a spell checker.
Or I would have simply gone without. It's amazing how long I can go without needing to process words.
Most of the obvious avenues are oversubscribed. Either by people from poorer countries who can undercut you, or by full timers who can commit more than you.
Seems to me the obvious ways to make this pay are either work on something in an area that pays well in order to get a job in that field, or do some market research and find out if there are any iPhone or Android apps (or even WP7) that people seem to indicate they'd be willing to pay for.
We're talking about kb. That b means bits. Bits are binary. that means 1024. There is zero ambiguity.
A data transfer rate of 1kb/s will be a thousand bits per second according to almost anyone who deals with data rates. I agree there is no ambiguity, but I find your comment confusing.
Considering this means that a 1KHz signal can carry a data rate of 1kbit/second, this is pretty useful. There's no utility to talking about powers of two here. If there was, then surely we'd say there are 10000000000b bits in a kb. Or maybe 400h bits in a kb.
Linux is a bit of a mishmash. For example the tools in KDE seem to specify MiBs and GiBs. "ls -h" and "du -h" looks like they use base 10, whereas "df -h" seems to use base 2, but doesn't use the Gi/Mi prefixes.
And how many bits were in those 18th century non-computer, non-binary bytes?
There weren't any. Scientists came up with a set of prefixes that they considered a reasonable standard. If you like standards then stick to the standard.
If you want to use decimal, please stick to the decimal "decabit". If you use "bytes", you are talking binary.
Why? Because some stupid engineers who didn't understand the SI system was decimal decided to attempt to apply it to a binary system, without realising that raising to higher powers increases inaccuracy, and since they did something stupid we should stick with it, even though it makes no sense for hard disks, and there are perfectly good alternatives?
I may have been being a little generous. Bignum division is a fairly slow process. But if we're trying to find the factors of the product of (2^n-1) and another prime, we don't actually care whether our candidate (2^n-1) is prime or not. We just try every n up to 57,885,161.
Although now you explain the details I can see how the technology to establish whether numbers are prime has applications for cryptography.
Surely a power of 2 minus 1 is useless for cryptography though. It's a common way to produce a prime, but checking a number for a prime factor generated using this method would take just seconds even on a normal home computer.
It's possible that that is simply a mock-up they used for the cameras. This is pretty common amongst western countries so Iran could be the same. And Iran is spending a fair chunk of cash on science and technology. Plus they have had some access to Russian technology so that should give them a decent leg-up.
I'm not willing to commit to saying this is legit, but I'm reluctant to dismiss it out of hand as well.
Iran does have its own home made drones. Drones are actually pretty simple because a lot of the work goes on making them cheap rather than making them technologically advanced.

Do Teslas not work in the cold?

The spinner has come to mean "broken".

Source compatibility is pretty common, but aren't the current bank computers binary compatible with the early 360's from the 1960's?

It's basically the ultimate hipster phone.

Well, yes, but if a company pays that they'll want a certain level of commitment. Not just a weekender.

I heard once it was because age implied wisdom. Seems to make sense in the context anyway.
Noah lived to over 900, and he was building Arks into his 7th century.
These modern God-botherers just don't have the stamina.
There weren't any. Scientists came up with a set of prefixes that they considered a reasonable standard. If you like standards then stick to the standard.

k, has meant 1000 since the 18th century. the other SI prefixes have been around in science longer than they have with computers.
Sadly though, for practical purposes, the law is what's enforced rather than what's written.
Relative to the cost of a soldier this seems reasonable, assuming British soldiers have a similar cost.
Surely, if your business model relies on selling copies of your software, then going GPL is not going to work. What was he expecting?
