Thunderbolt vs USB 3.0 vs eSATA

Thunderbolt vs USB 3.0 vs eSATA | News | TechRadar

eSATA delivers 3Gbps, with older eSATA 1.5 devices offering 1.5Mbps; USB 3.0, also known as Superspeed USB, goes up to 5Gbps; and Thunderbolt is a very respectable 10Gbps. As Intel puts it, that’s enough to “transfer a full-length HD movie in less than 30 seconds”.

The New Yorker on Minecraft’s creator, Notch

 

Since the game’s release, in 2009, Minecraft has sold in excess of twenty million copies, earned armfuls of prestigious awards, and secured merchandising deals with LEGO and other toymakers. Last year, Persson earned over a hundred million dollars from the game and its merchandise. Persson—better known to his global army of teen-age followers by his Internet handle, Notch—has a raggedy, un-marketed charm. He is, by his own admission, only a workmanlike coder, not a ruthless businessman. “I’ve never run a company before and I don’t want to feel like a boss,” he said. “I just want to turn up and do my work.”

Each Minecraft sale flows straight to Mojang’s pocket—there are no middlemen—and, since the game is digitally distributed, there is no physical product to manufacture, store, or ship. After Minecraft, none of Persson’s subsequent games need to turn a profit. In 2011, he gave his £2.2 million Mojang dividend to his employees. “The money is a strange one,” he says. “I’m slowly getting used to it, but it’s a Swedish trait that we’re not supposed to be proud of what we’ve done. We’re supposed to be modest. So at first, I had a really hard time spending any of the profits. Also, what if the game stopped selling? But after a while, I thought about all of the things I’d wanted to do before I had money. So I introduced a rule: I’m allowed to spend half of anything I make. That way I will never be broke. Even if I spend extravagant amounts of money, I will still have extravagant amounts of money.”

The Cubicle with a Hidden Gaming System

What an excellent idea. :-)

The Cubicle with a Hidden Gaming System:

Lifehacker reader JonesyVan’s workspace looks like your typical cubicle. Hidden in the filing cabinet, however, is some serious entertainment for break times (i.e., “when Bossman decides to exit his office”): a wall-mounted TV and Xbox 360.

Xbox Live – error code 80048821

Last night, when logging into Xbox Live, it wouldn’t let me log in and ultimately gave me “code 80048821”.  

Screen Shot 2013 04 04 at 10 07 06 AM

The full text of the error was:

“Sorry, either that’s the wrong password, or the email you entered doesn’t have an Xbox LIVE membership.  Please try again, or got to Xbox.com/forgot if you need help.  Code: 80048821”

This code is not listed in the list of codes on xbox.com, and most of the results of a Google search returned info on Windows Live Messenger, not the Xbox.

After resetting my password and trying again, it still didn’t work.  I finally gave up and called Xbox Live support, where I talked with a very helpful tech.  He suggested re-downloading my profile, but that didn’t fix it.  We made sure that my Xbox Live Gold membership was renewed and in good standing (it was).

Next, he had me clear the Xbox’s system cache.  The steps were:

1) Go to Settings, and then System.
2) Select Storage.
3) Select Hard Drive, and press Y
4) Select Clear Cache, and press Yes.

After rebooting the Xbox, everything worked fine.  I’m not sure if clearing the system cache was sufficient to get it working, or if I also needed to re-download my profile, but these steps fixed the problem.

Paleo author reviews anti-paleo book

Paleo author reviews anti-paleo book:

The new book, Paleofantasy: What Evolution Really Tells Us about Sex, Diet, and How We Live, is billed as an “exposé of pseudoscientific myths about our evolutionary past and how we should live today.” It was written by Marlene Zuk, a professor of ecology, evolution, and behavior at the University of Minnesota.

Many people who follow the paleo regimen have reviewed the book on their blogs, but my favorite review so far is by Mark Sisson, author of The Primal Blueprint (my favorite paleo book). He says the problem with the book is that no one who follows paleo believes any of the straw man premises she sets up. In other words, Zuk’s idea of Paleo is the real paleofantasy and her arguments against her own straw man version of paleo were explored and accepted years ago by the Paleo community.

After reading the book, John Durant tweeted “Paleofantasy shouldn’t have been a book in 2013, it should have been a blog post in 2010,” and that’s as good a description as I can think of.

It’s all very uncontroversial:

There is no one paleo diet.

Who’s saying that? Humans have spanned the globe for millennia, surviving and even thriving in environments ranging from tropical to temperate, from arctic to near-aquatic, all the while subsisting on the wild foods available to those regions. Same basic diet of animals and plants, different configurations.

Evolution doesn’t just stop and humans didn’t just reach a state of perfect adaptation back before agriculture from which we’ve never progressed.

Sure. I talked about how we’re still “evolving” last year, even mentioning Zuk’s favorite topics – lactase persistence (35% worldwide, which is far from 100%) and amylase production. She discusses a few more recent changes, like malaria resistance, adaptation to high altitude, and earwax differentiation, but that’s it. If she wanted to, I’m sure she “could keep adding to the list” and mount an overwhelming case for widespread genetic adaptations to grain consumption, chronic stress tolerance, and sedentary living, but she’s saving up material for the next book. Or something. Either way, I’m not very convinced by her “list” of rapid evolutionary changes, especially considering most of them have little to do with the mismatches we discuss in this community and none of them are even present in a majority of humans.

Zuk is also quick to misrepresent “our” arguments so she can swoop in and take the sensible position – positions the ancestral health community has long occupied!
