ajslater··on Headphones for Hackers
If they really wanted to indulge in bullshit science they should've correlated headphone brand and model to exit valuation.

Heroku should have a badge in their footer 'powered by Beyerdynamic'

Is there an fn() syntax so I can plot recursion and bifurcation?
ajslater··on Why I’m Kissing Spotify Goodbye
The number of grandstanding blog posts where people publicly declare why they're not using a particular website is a metric of success.
ajslater··on I Hate My Smartphone
His chief criticism is that its not his general purpose computer with a full sized keyboard and he doesn't like the popular, social uses for mobile technology. I don't think anyone can help him with that.
ajslater··on All of life has been utterly, profoundly changed thanks to Facebook...
And no one's "pulled back" from chat. Now its ubiquitous and how many of us conduct all communication at work and much of personal communication.
ajslater··on The economics of good looks
..and looks stop mattering completely the moment people start speaking instead of looking and deciding weather or not speaking will be interesting.

How you look signals what sorts of conversation are likely to be possible or interesting. e.g. if you really like knitting, go talk to the person wearing the nice custom sweater.

ajslater··on What I learned today: Never apply for a job
This is very strange advice. I've never gotten a job from an acquaintance and am never likely to. There's a much bigger pool of jobs from people you don't know and a much better chance of a good match being made somewhere in that pool. The numbers are obviously in your favor despite the fact that people you've worked with know you're good. Its unlikely that you and people you know just happen to want to do the exact same thing at the exact same time with everyone else looking to recruit you.

I'd also feel really weird getting a job via acquaintance. Its like a kind of nepotism I don't want or need.

ajslater··on Electrons Are Near-Perfect Spheres
Strictly speaking, I don't think these things have a 'size' with a border where you can be inside or outside of a lepton 'surface'. Its a basically a point source with a field effect as far as we can determine. http://en.wikipedia.org/wiki/Classical_electron_radius

I think the article is saying that the field affect appears to be completely uniform.

Technically, if the electron can affect something at a great distance via gravity or releasing photons you could say the size of an electron is many light years in diameter. Or you could call it infinitesimally tiny.

Neutrons and protons we know to be complicated little parties of quarks and gluons, each of which are, as far as we know, are also elementary particles like leptons.

ajslater··on Why do people resist the idea that carbs are worse than fat?
In the literature its referred to as N.E.A.T. Non-Exercise Activity Thermogenesis

Many people's body's response to overfeeding is to up NEAT, up fidgetyness. But not always. Your body thinks getting fat is a good thing. Famine used to be common. When dieting almost everyone down-regulates NEAT. On a severe diet you feel like being very still.

ajslater··on Eating Healthily for $3 a Day
So, for the uninformed peanut gallery, beagle3 is just plain wrong. Probably not intentionally, he's likely also fooling himself. But you locked him in a room and measured his food for him and really only fed him 1200kcals per day, even at a fairly sedentary level of exercise, a 220lb man would lose a lot of fat mass over several weeks. And no beagle3, human bodies tend to be very greedy with calories and do a good job absorbing them regardless of what you smell.

What likely happened is that reducing carbs reduced beagle3's appetite and he ate less. Unless...

...unless beagle3 has a magic body that has never once been seen in any controlled experiment. But he probably does, since every dieter who has problems believes they have a special body that science can't explain. So they buy a book and a program from someone who tells them what they want to hear. And if their guru is on their game they sell very very expensive supplements.

Because its a well known scientific fact that the first law of thermodynamics applies to everything in the universe except a disgruntled dieter.

ajslater··on Eating Healthily for $3 a Day
I'd bet a fair amount that your Mass General study used self reported calorie intake.

800kcals a day is typically enough for a 100 lb person to lose nearly a half a pound of fat a week. That's low calorie by most people's measure. Certainly mine at 200lbs

When most people are talking about 'losing weight' they mean losing fat. At least losing actual body tissue. Anyone can gain or lose 10% of their body weight in a few days by controlling for carbs. But its just water.

Try to ignore rat studies if you possibly can. Their metabolism, particularly their capacity for denovo lipogenisis is very very different than that of human beings.

ajslater··on Eating Healthily for $3 a Day
Taubes is a quack, pure and simple. Most of the studies he cites that I'm familiar with use self reported food intake. Any study that uses self reported food intake should be entirely disregarded for physiological purposes (perhaps useful for studying psychology).

You can get razor sharp lean on a diet with lots of carbs in it and you can get nice and fat on a ketogenic diet.

No controlled calorie study supports the idea that carbs, fats or proteins have any particular metabolic advantage over the minor differences in their thermic effects of feeding (TEF) (essentially energy required to digest).

Compares One Vote, Instant Runoff Voting, Acceptance Voting, Ranked Choice Voting, Condcorcet Method and various methods of Rated Voting via simulation testing for maximum voter happiness with the result.

The sad thing is that while Taubes is a quack and his book title is quackery, he probably is 40 years more up to date than many nutrition or medical professionals. USDA sucks pretty bad.
ajslater··on Why I left Facebook
Pretty common to see grandstanding "I left" posts for Facebook. Not as much Twitter. Or really any other service that someone just stops using without devoting an entire blog post to the minutiae of how and why.

Coming up next: WHY I LEFT COLOR.

Edit: I too was looking for gossip from a former engineer.

ajslater··on The Decline of Facebook As A Social Network
The same as not for business. Its just another communication channel with its own advantages and disadvantages. So, yes, that and more.
ajslater··on The Decline of Facebook As A Social Network
The real problem with Facebook is the symmetric friend model. I have 70 FB friends and a couple of those would be removed if it were politically convenient.

Twitter does it so much better.

I wonder if the FB gods ever run statistics of how many people are "friends" and have mutually hidden each other.

ajslater··on The Decline of Facebook As A Social Network
Your problem is cured by creating a Facebook Fan page. Many famous people's Facebook problem could be cured with that.

ajslater··on GNU Hurd in Google Summer of Code 2011
Webservers can handle a big OS. The hardware is typically over specced as it is. You might find some utility in shrinking/streamlining the OS for embedded or mobile.
ajslater··on GNU Hurd in Google Summer of Code 2011
I knew I must have been misunderstanding you. No, I am not aware of any.

Everyone who cloud hosts? From Amazon to Linode? http://www.linode.com/wiki/index.php/PV-GRUB

I was talking about client workstations in non-technical environments where central command wants to be able to patch your OS. The Hypervisor downloads OS of the day and runs it, the OS downloads personal settings from some shared server and you have your environment on a disposable workstation.

ajslater··on GNU Hurd in Google Summer of Code 2011
They are. They're called hypervisors. The way I hear it Xen et alia are the new hotness in deploying Windows across the org in IT.

Exactly. OP is doing gymnastics to solve a non-problem.

I can't agree with rdl more. You should re-stage your poll.

They license their technology to PayPal, and perhaps others. What the rev deal is, I have no idea.

ajslater··on CES2011: The end of the PC era
I knew a senior manager at Intel. The company encourages you use the words 'significant competitive advantage'. Not that ugly 'M' word.
