Comment Re:Windows 7 end of life... (Score 1) 681

Well honestly, if you ignore the whole Metro UI fiasco, Windows 8 is a nice update to Windows 7. There a lots of little improvements. It may sound silly, but I think the dialog boxes for copying/moving files alone would be worth a $20 upgrade for my own use.

My two main qualms with Windows at this point are (a) forcing users to use a touchscreen UI on the desktop; and (b) the requirement of stupid/annoying copyright protection schemes. I don't pirate and I don't have any problem paying for software, but product activation needs to go.

Comment Re:Communication is more than syntax (Score 1) 219

Yes they did. There is more to communication than the specific words used. Tone, timing, delivery, emphasis, etc all are part of the message. If Facebook altered any of these to be different from the expectations of the user without informing them beforehand then they changed what people said. There is MUCH more to human communication than the syntax used.

I'm not sure how you think they changed the tone, timing, delivery, or emphasis of the messages. Apparently they used real posts and posted the entire content of each post without alteration. From what I understand, though I'm interpreting from a few different stories that I read, all they did was to alter the algorithm that Facebook already uses to choose which posts to show in your feed. They didn't insert or remove words from the posts. They didn't do anything to really re-contextualize them.

Whether people realize it or not, Facebook already filters and resorts your feed to emphasize posts that they think you're interested in. If you pay attention, you'll notice that when you have a friend that you "Like" a lot of their posts, then more of their posts will show up in your feed, and they'll appear higher up. I suspect that they also do things like prioritize posts with links from friends who you follow their links. I think they probably even do things like, if you've looked at a persons' profile a lot, or perhaps even if they look at yours a lot, the posts will be more likely to show up. I doubt that Facebook has made this algorithm clear, but it's clear that they're doing things like this.

So it seems that all they did was to add into the algorithm for some users to favor posts with happy words, and for other users posts with unhappy words. I don't think they're altering anything about the tone or emphasis of any individual message. I don't say this to really defend them.

Comment Find a different partner? (Score 4, Insightful) 236

Maybe Google should be working with a company like Tesla instead. It seems like Google would need to find a partner that a background in manufacturing cars, but was a little more innovative and forward-thinking than the big guys in Detroit have historically been.

Along with everything else, my guess is that if this technology really becomes commonplace, it will be disruptive and it will likely result in fewer people actually owning cars. In cases like this, sometimes getting businesses with entrenched interests onboard is not only difficult, but counter productive.

Comment Re:This is not advertising (Score 4, Insightful) 219

As far as I could tell from reading about this, they didn't change what people said.

Here's the thing, Facebook already filters what you see with the default setup. Your 500 friends each post 10 posts today, and when you load up your page on a social networking site, the page only displays 15. So how are those 15 chosen? (I'm making up numbers here, obviously)

The obvious choice would be to show the 15 most recent posts, but that means there's a good chance you'll miss posts that are important and that you'd like to see, since you're only getting a brief snapshot of what's going on in that social networking site. Facebook instead has an algorithm that tries to determine which of those 5,000 posts you'll care most about. I don't know the specifics, but it includes things like favoring the people who you interact with most on Facebook.

So what Facebook did in this study is they tweaked that algorithm to also favor posts that included negative words. The posts were still from that 5,000 post pool and the contents of the posts were unedited, but they subjected you to a different selection in order to conduct the research.

It's still an open question as to whether this sort of thing is appropriate, but it's important to note that this is something Facebook does all the time anyway. I think where is gets creepy is that Facebook is also an ad-driven company, so you have to wonder what the eventual goal of this research is. I can imagine Facebook favoring posts that include pictures of food to go along with an ad campaign for Seamless. Maybe they'll make a deal with pharmaceutical companies to adjust your feed to make you depressed, while at the same time plastering your feed with ads for antidepressants.

Comment silent vibrate. phone on wrist. chakra. watersport (Score 1) 427

I liked the idea of that kickstarter waterproof thingy. Would be nice to have a phone on my arm while surfing... Only the boss can then bug me and its not really very waterproof.

I view it as a phone that you strap to your wrist. I only wear watches for travel. A phone that you strap to your wrist is just a little bit more convenient. You have vibrate better. Its also away from centre of the body so its a little away from your chakra line if you go in for that kind of thing.

Education

What's Your STEM Degree Worth? 148

Jim_Austin writes A recent study by economist Douglas Webber calculates the lifetime earnings premium of college degrees in various broad areas, accounting for selection bias--that is, for the fact that people who already are likely to do well are also more likely to go to college. These premiums are not small. Science Careers got exclusive access to major-specific data, and published an article that tells how much more you can expect to earn because you got that college degree--for engineering, physics, computer science, chemistry, and biology majors.

Comment Re:Administrators (Score 2) 538

In all aspects of education, from primary school to university, the growing swarms of administrators soak up the budget. In some school systems, they vastly outnumber the actual teachers, have better pay, and yet contribute nothing to the operation of the schools.

Don't forget those in the construction industry. Like administrators, they contribute where it counts: in the voting booth where they help elect those that will continue to increase spending on that abstraction "education" rather than on actual educators.

Comment Re:For a sense of scale (Score 4, Informative) 142

There are other advantages to shrinking components. Higher clock rates become possible.

You'd think so, but the problem is global interconnect. Not gates. It was all the way back at the 250nm node when interconnect and gate delay were about the same.

At the 28nm node, wire delay is responsible for something like 80% of the time it takes for signals to work their way through a circuit.

And it some cases inverters are actually used to help signals propagate more quickly down long wires. In other words, long wires are so slow compared to gates that adding gates can speed things up!

I believe many ISPs are actively sabotaging customer's connections to some of the internet's content

They don't have to. The protocols we use are more than capable of screwing with things.

Consider TCP: the protocol is BY DESIGN meant to exponentially increase the amount of data dumped on a link until it overloads and begins dropping packets. TCP then throttles for a little while and then soon goes back to bashing the network with packets until it breaks again.

Comment Re:I can't think of a better argument... (Score 1) 387

I feel like archival settings might be even trickier. There are two additional problems that jump to my mind.

First, it would mean you'd want to recheck the hash on a regular basis, and doing that cheaply is a bit of a logistical problem to solve in itself, but it only raises the question: what do you do when the hash comes back bad? The best solution that I can think of is to develop a system where the data is automatically duplicated to another medium and both are checked regularly, and if either one turns up defective, you restore it from the other copy. I don't know if this is what you had in mind, but the best option in this case might be to load all the data from the flash media you receive into your own server and use a filesystem with it's own check-summing to prevent bitrot. You could then keep that server backed up effectively and efficiently and reuse the USB keys. All this would increase the complexity of the operation, but probably work better.

The second problem is making sure clients can manage, find, recall, and decrypt their data once you have it. Imagine I periodically ship a 32 GB drive to you, and eventually I've shipped 20 of them out to you. I'm a good customer, spending a bunch of money with you. Now I go, "Hey, I want this specific file back, but I don't remember what key it's on, and I don't have the decryption key anymore." Yes, if I do this, I'm an idiot, but when you're dealing with customer service for the general public, you're dealing with idiots. So my question would be, how are you going to keep that from happening?

So there are a couple different problems here. One might already be solved by the software you plan on using to encrypt/hash the data. Does it keep an index of all of these archives that the user can search? Ideally, if you dumped things to a server like I mentioned earlier, there would also be a way for clients to connect remotely and view the contents of their archive, assuming that they have the correct encryption key or password. But then there's a second problem: If you're safeguarding against people losing this data due to a computer crash, fire, flood, etc., how do you make sure they have a backup of that index and the encryption keys? I kind of feel like, now you need a second service that does the same thing, just so I can ship the index and keys to *that* service. Or only require a password and not encryption keys, I suppose.

The idea has some potential. Figure out the best media for it-- a specific model of external drive that's rugged, high capacity, but also light/thin for cheap shipping costs. Figure out a fitting rotation scheme to keep the price down. For example, if you dropped a new backup in the mail every morning and kept them all offsite for a month, you would need at least 30 drives (ignoring the time it takes to ship the drive offsite and back). That's potentially a lot of money, plus shipping and warehousing costs.

Alternatively, you could do something where you try to time it so they drop it in the mail at the end of each week, and they receive it back two weeks later-- basically they ship it to you and you almost immediately ship it back-- so then they'd only need 2-3 drives. If you held onto one drive per month for 3 months, and then 3 monthly snapshots per year, indefinitely, then that means you'd need 3 drives to be in the weekly rotation plus 3 for the monthly rotation, plus 3/year for permanent offsite, it means you (or the client) need to buy 6 drives + 3/year. That doesn't seem so bad.

Like you said, make sure they're encrypted and hashed, not just to guard against bitrot, but to guard against snooping and damage in transport. All in all, that might not be a bad solution for areas that are rural enough that you can't get Iron Mountain, and your Internet connection is too slow to push your backups over the Internet. I don't know how large that market is or how much they'd be willing to pay.
