Durability is not generally designed into current smartphones. Intentionally. Think about the volume of sales, and how they would decrease, if devices didn't break within about 2-3 years. In fact, durability nearly sank RIM - as most people were comparing new iPhones with the original bold - released at the same time as the original iPhone.
2-3 years is an eon in mobile right now. If devices don't die, people don't upgrade.
Hadoop tops out around 4000-6000 nodes, then you run into serious scalability issues in the jobtracker and HDFS scalability. Granted, with HDFS federation and YARN these should improve, but today you can't build this wider than a few racks without spending a good chunk of time doing some significant hadoop engineering.
Second, disk. Where's the disk? Hadoop needs disk. Hadoop likes disk. Disk likes hadoop. Hadoop likes lots and lots of disk. Nice, you've built a 6 watt SoC. Now just put six 10 watt 1TB drives beside it and I'll be happy. Oh, and make sure the disk controller can do spindle speed on all six.
In my case, I didn't even talk about the major advantages like the complex analysis. 100 billion row joins don't sell execs. I did it purely based on the cost vs. enterprise grade storage. That got it in the door - and then I was selling the platform to developers. Showing a dev team a little pig script written on the spot, then sending it out on a production cluster and watching it use 800 cores and 8TB of memory, processing a few dozen TB of data while we're sitting in a room, and the devs got on board. Now I've got new dev groups wanting onto the platform regularly - and the execs keep hearing about how this hadoop thing is a critical part of their app/service/report. It sells itself, after a point.
I'm biased, as my entire job is building those systems so many people refer to as "big data" - but the marketing is terrible. The technology itself is quite good, and makes a huge amount of sense. The problem is, companies traditionally used to doing data stuff for large corporations (ie, EMC, Oracle) are pissing themselves. This destroys their entire business model - so they're flooding the market with crap trying to avoid losing absolute boatloads of money and accounts to these technologies.
Talk about big data with those companies all you like, and they won't mention the actual reason hadoop and the like are a big deal: 1- It's all open source. Don't wanna pay? Self support. 2- It's all designed to run on the cheapest commodity hardware you can find. Why buy appliances with huge markups?
This has companies used to huge margins on appliances and software shitting themselves. They tried FUD with single point of failure stuff, and now that that's solved, they're stuffing infiniband into custom rack designs and saying how much better it is. Meanwhile you can buy 4x the gear for that same price.
Is it a buzzword? Yup. Is it saturated with marketing? Yup. Is it a stupid idea? Hell no.
You misunderstand. I'm impatient. Now that I'm actually capable of running a reasonable distance, I get annoyed walking because I could be getting there faster!
I actually had the opposite reaction. I'm 31, and I constantly fight the urge to run everywhere. I remember all through school, even into early highschool, I'd run everywhere I wanted to go.
Then it was uncool to run. Then inappropriate. Then unprofessional. A year ago, effectively 15 years after I stopped running everywhere, I started running for exercise. I'm getting back into shape. And I'm finding it annoying that I can't just run all the time - I'll get sweaty or smelly, and that's just socially unacceptable.
I'm pretty sure we're all meant to run a LOT more than we do - and we've forced ourselves to stop due to social pressure.
You're an idiot. You signed something under threat of prison / arrest without bothering to consult a lawyer.
Actually, that's exactly what he should have done. If you're ever presented paperwork, and presented a choice at which point you must choose right there and then, sign it. It's compelled/under duress.
Several of my former employers had a policy on termination where you must sign an agreement stating you won't sue for anything (wrongful dismissal, etc) in order to get a generous severance package. But, you have to make that agreement there, in the room, before they walk you out of the building. I ran this past a few lawyers, and they all said the exact same thing: if you're under duress, sign it right away. Agreements that are signed under duress are void.
It's not incorrect. ASKAP is referred to as a "pathfinder" project - an initial proof of concept that will eventually be rolled into the full SKA array -- most of which will be in South America.
The SKA organization only came into existence formally last year. The ASKAP project was in progress long before that. SKA is in the "pre-construction" phase now, and won't even start building telescopes themselves until 2016.
Seriously? He made two comments on twitter, of which he's an active user, and the media picked it up. I don't quite see how that's trolling for attention.
You, on the other hand, seem to be doing quite well at it.
I've always grasped the limitations of special relativity - it's made this conversation especially interesting to read. That said, you just touched on one thing that has consistently been beyond me. Can you expand on this a bit? General relativity - and many of the corollaries in the early universe (specifically the inflationary period) have been things I've struggled with.
How can you have two objects moving away from each other at greater than the speed of light, whilst maintaining special relativity? For inflation to work, that has to be the case, correct?
And the fact that you still get 8 hours browsing, even over LTE, is really impressive. It might be slightly shorter than browsing time on an original iPhone but how much browsing could you have got done on Edge? You could probably read 10x the content on the iPhone 5, so how is it not far ahead?
It comes back to the problem of looking at a raw number on a list, without thinking what that number MEANS to a user on the device.
Great example of cognitive dissonance. The point of the article is that taking into account technology changes, this iphone isn't any better than the original. And you just argued "but but but... new technology!"
You're not reading enough bureaucrat. They're saying they'll consider invading Ecuador to get him.
The embassy is, both legally and by convention, part of Ecuador itself. When they say they'll "take action to arrest Mr. Assange in the current premises of the Embassy" means they're coming in without permission. Which, from Ecuador's perspective, is not very much different from saying they're going to come and arrest him if he was in their capital.
I imagine most of it was memory allocation - Linux's malloc() has much different performance characteristics than Window's malloc(), and that's 90% of your kernel calls right there.
*twitch* malloc() is not a kernel call, its a library function only. man 2 brk.

Except for a few problems:

Nope. This exact thing has happened before - except it was Nike, not Apple:

Yes, because apple is the only company that does high-dpi displays.
(Actually, that's unfortunately pretty true right now, but I hope to start seeing better displays out of the hardware makers soon.)
They already do. Just try to contribute to Hamas. See how well that goes over.
And while GPL may not be viral, it is my-way-or-the-highway.
Show me a license that's not "my way or the highway". In fact, show me any legal contract that's "my way or... you know, do whatever you want."
Blah... Built in South Africa, not South America.

Did the original iPhone have 225 hours standby?
No, it had 250.
And the fact that you still get 8 hours browsing, even over LTE, is really impressive. It might be slightly shorter than browsing time on an original iPhone but how much browsing could you have got done on Edge? You could probably read 10x the content on the iPhone 5, so how is it not far ahead?

Seriously? Dood can't brew beer in his spare time without it being politically motivated?
Timing might be politically motivated for releasing the recipe, but I highly doubt the beer is.
Yes, because nobody has their own proprietary data sets to use.
Hadoop is a tool. How you use it is up to you.

And for good measure, now the actual paper:

Funny thing, I was reading this last night.
Read the paper. They make rather optimistic assumptions about Moore's law.
My god these posts are annoying.
Does an Indian businessman who bought a Blackberry...
Does an American businessman with a Blackberry...
Do they have a BES? If they have a BES, nothing to worry about. Next question?
And, if memory related stuff is anywhere close to 10% of their system calls, they're doing it wrong.
I imagine most of it was memory allocation - Linux's malloc() has much different performance characteristics than Window's malloc(), and that's 90% of your kernel calls right there.

Come on, 37G isn't big data. You'd have a hard time arguing 37TB is big data.
Cool stuff though.
