In other words, a cash grab. Brazil isn't the most enlightened country when it comes to spying, so this is a little "pot kettle black" situation, but really its just an excuse to try to force more companies to spend more money in Brazil. It has absolutely nothing to do with the feigned "outrage" the politicians are espousing.
As any good coder knows, the base case is often times the easiest, what is going to be challenging, at least from a practical perspective, is how these autonomous cars deal with failures/inconsistent data in their sensors. My guess is that all these demos were done with relatively new, clean and maintained sensors, but what happens if someone just lets their equipment go to shit, what happens in rainy/snow environments where mud/snow may gum up the sensors, etc. I think that even 7 years might not be time enough to solve these problems, at least not without new, potentially unpopular legislation dictating that maintenance standards for automobiles come at least close to those of airliners.
I am just imagining you sitting on a couch, talking to a hard disk:
You: Well Mr. Hard Disk, how are you feeling?
Hard disk:Doc, I tell you my head feels like its constantly spinning in circles, and I am afraid something might come unhinged and I'll crash!
Money is probably the biggest factor, there just isn't enough money allotted to trying to reproduce experiments. Most budgets only exist for new/continuing research, not verifying experiments done by others. And as the cost of doing experiments rises(more sophisticated equipment necessary, lots of paid "volunteers" etc) this is only going to get worse.
Second, although not as important, is the "glory" factor. Very few talented scientists want to spend their time and research money on reproducing experiments done by others. There aren't a whole lot of publishing opportunities in doing so, esp. if you cannot refute what they have done. You can see this to a certain extent in the open source world as well, for all but the most famous of projects you tend to have a very large # of projects that essentially do the same thing. Why? Because a lot of people want to "invent" a new program rather than improve upon what is there. Fortunately in the OSS world money isn't nearly as much an issue, so you do have large #s of people improving OSS rather than trying to re-invent the wheel.
AKA Dracula, so the summary is right. He has issues with waking up during the day, and thus cannot sleep at night. Finally, the metaphor has been explained!
Ah ha, thanx for the reply.
I've a question. I'm Canadian so I don't know. Just curious.
Why can't you just go to a government office and sign up for Obamacare? Or can you? Personally, why people are surprised that a government website can't handle high traffic baffles my mind. What government website ever did? Anyho', really just interested in my first question. One factor I've been aware of is that the plan is administrated through the States, so I'm wondering of states hostile to Obama (Republicans) aren't offering it at their state or municipal offices?
It would be great for supercomputing if there were more commodity cpus that had multiple vector units per core, but unlike GPUs, where gamers subsidize a lot of the research, development, and production of high performance hardware, there is just no demand outside supercomputing for more than one vector unit per core on a CPU. So at least for the time being we may see the current pattern continue: someone will come up with the funding for a custom cpu that will have multiple vector units per core, leapfrog everyone else for a while, then eventually fall behind commodity hardware as they do not have the resources to continue developing their hardware designs for their very small customer base. Rinse and repeat.
