Comment Re:MapReduce is great (Score 0) 147

I'd say its really this.

You have a business problem which is completely unrealistic to solve via. vertical scaling on SQL Things in the range of 50-200k CPU hours Hadoop is good for. SQL solutions are pretty dreadful at 1000 CPU hours type workloads. BTW petabytes and exabytes. SQL is pretty good for terabytes.

Comment Re:People don't care because ipv4 works for them (Score 0) 54

The internet won't be ipv6 only it will be ipv6 primarily. I think it would be very very fast. Consider the basic home user getting a /60, that is 16 home subnets each larger than today's internet to allocate addresses from. Devices themselves can default to an address (their subnet + mac), random or the home user (including things like the home router) can provision them out manually.

devices with an Ipv4 dynamic address using NAT would still exist but the permanent address comes almost immediately after the ISP makes ipv6 available to the home.

Sure. If the USA decides a particular corporate activity is in the national interest then the CIA can freely back it. We had a lot more crony capitalism 1930s-1970s and it showed across all areas of government, including the first 3 decades of the CIA. My point is that this is not a blanket guarantee. They can also act against corporate interests freely when they deem it appropriate.

The reason to develop for them is that Apple has a huge share of the 400m consumers who spend the most on applications.

As an aside, vertical applications don't have this problem. They aren't easy to clone as the developer often has to have business partnership relations with desktop / server / SaaS companies. You often don't have to give up a percentage as the app is included (free).

That a radius is 1/2 a circumference and you can move the 2. And yes people miss those sorts of things all the time in interviews. I was also thinking about derivation formulas 4*(1 - 1/3 + 1/5 - 1/7...)

As for why transcendental matters mainly I was trying to pick something that's only doable with fairly advanced knowledge. Basically this tests the person understands graduate level Galois theory.

AWS is just a bucket for storing my website assets over the Internet.

No it vastly more than just a big hard drive. There are 3 main computational theory about parallelism and AWS introduces specific complexities. This is not an easy topic.

I don't use sort algorithms for 99% of the code I write at work (IT stuff) and home (web development). I know how to implement binary and bubble sorts. If those don't do the job, I'll look for something else in the "Mastering Algorithms with C" book. ;)

The point isn't if you can read the book. The point is how much you already know. I can read French with a dictionary I can read English without one.

The companies have to respond to what you aren't testing. Project based testing does a good job of testing things like collaboration skills and research skills that individual tests don't. Individual testing with no access to outside information tests depth of knowledge on hand.

Of course. But do you know which sort algorithms are required when? What the tradeoffs are? Since we are talking AWS how various algorithms decompose with out of order execution or on various configurations of network speed, disk speed and memory? Etc..

You can look all that up. But if you need to look it up then you don't know algorithm theory.
