I run four days a week, climb, and lift weights; my maximum bench was 315lbs. I'm also 5'8" and weigh 200lbs, giving me a BMI > 30. By this university's standards, I'm thus obese and require supplementary physical education.

When I was seriously into bodybuilding and weighed 175lbs, I looked like a take-home size action hero. Six pack, huge arms, etc. My BMI at that time was 25.8, which is still considered 'overweight', and 'unhealthy'.

I'm all for encouraging fitness, but using some totally worthless metric to determine who needs to take a PE class is, at the very best, a waste of time and a blatant tax on the students.
This -- "0" -- is the number "zero". Here is how you use it...

I don't see raw speed as being the issue.

Even when you edit a 500-slide powerpoint, all you need at any given time is to see the current slide. Same for word processing.

Rather, I agree with the original poster that it's the APIs that are the weakest link. HTML and CSS are ugly APIs when you think of GUI development.
Interesting feature, I wonder what caused it to come about. Perhaps GitHub is looking to hire and wanted first pick :D

GitHub has a lot of little hidden features these days. The ability to do code review is there, but very hidden, any plans for improving that workflow? On the topic of hidden features is there a graph showing off what features people use (and don't?) I was recently told about one that has been around for a long time that I just didn't know about. no doubt there are others.
It's really a question about consciousness, rather than having or not having an option; that's what free will is about.

'Second birth' for mistaken coma victim
A good article, but I'm wary of the idea that you can solve the problem by spending just as much time, only on a different kind of solo computer game.

Solo computer games are fun for recreation* but until the AI in them starts approaching humans levels they will never challenge you the way real people can. Learning a martial art, studying math/computer science or playing a team sport (even if it's a LAN strategy game) seems to me a much better way to build muscles (physical, mental, social).

*but playing them too much is probably a sign of akrasia... http://lesswrong.com/lw/15w/experiential_pica/

However games which train actual working memory (e.g. Dual N-Back) may be an exception.
I recommend the movie Johnny Got His Gun: http://www.imdb.com/title/tt0067277/.

Being stuck, aware like that, seems too damn horrible.

Movie's plot: "Joe, a young American soldier, is hit by a mortar shell on the last day of World War I. He lies in a hospital bed in a fate worse than death --- a quadruple amputee who has lost his arms, legs, eyes, ears, mouth and nose. He remains conscious and able to think, thereby reliving his life through strange dreams and memories, unable to distinguish whether he is awake or dreaming. He remains frustrated by his situation, until one day when Joe discovers a unique way to communicate with his caregivers." Pulled from IMDB.
It does sound interesting, and for $50, I'd be very tempted to try it.

But yeah, who puts -1px letter spacing on their body copy? Ouch. Painful.
Meh. Looks like this guy should've taken an intro software engineering course and read a little Joel Spolsky instead of taking 5 years to learn this.
Typically, when you enter deep stage sleep your brain turns your normal motor functions off - it's supposed that this is to stop you from hurting yourself while in deep sleep (although some people suffer from sleep disorders where they do move).

In lighter stages of sleep this doesn't happen and you do move around.
Similarly: When my career-military ex husband was on recruiting duty, he and all of the other recruiters at a conference (state-wide?) were told they were "overweight" by the height-weight tables of some insurance guy there. Every last one of them had to pass the PT test to remain in the military and could not be overweight. (The military accounts for such possibilities and has an alternate "tape test" standard which generally works well for those guys who are "overweight" due to bodybuilding -- or did at that time. I don't know what the current standards are.)
You don't need a smart phone to use the product! Also, wi-fi is expensive, there's a reason we can price it so low :-).
We're definitely open to the idea of letting people play with communicating to our device.
James Randi: This Cruel Farce Has To Stop
Does it work with iPod touch + home WiFi?
I'm torn on this. On the one hand, I think not taking a required class is sufficient grounds to deny graduation. On the other hand, I think the college was out of line to require "obese"[1] people to take additional classes. The college has a responsibility to prepare students for their adult life, but (a) until I see evidence to the contrary, I highly suspect that special-ed classes for fat people are one of the least effective ways of achieving this goal (b) part of being an adult is taking personal responsibility. I'm not normally someone to whine about nanny government, but the college's policy strikes me as overstepping. My personal moral system also requires more from the students than passively not taking a class for the excuse of 'protesting' to fly, but others may disagree.

[1] Air quotes because BMI should not in any way be considered a reliable way of measuring obesity. Body builders will tend to be considered "obese" because muscle is dense and they have more muscle weight than other people their height.
fantastic timing for launch! I can just see it exploding with use come black friday and pre-christmas shopping
There are some newer countermeasures but openssl doesn't implement any of them.

I just took a quick look at 0.9.8h and this is still the case. The C code (aes_core.c) is the standard "alg-fst" version. The asm code in the subdirectory is faster but has no masking.

In short, if you want timing attack resistance, you can't just expect it in standard libraries.
It works quite well with the Lucida Sans Unicode, if only they'd spelt the font name correctly.
The best thing about the web is that it slows down UI development, and forces developers to actually think about what they are doing.

It also makes it easier to run a decoupled data / interface system, rather than GUI development, where it's easy to build the data and models into the interface.

Web development is like going through a minefield with your feet tied together. It's not ideal, but at least it slows you down.
Techcrunch needs an editor. That article was full of typos.
Competing DNS Roots [pdf]
It's funny how the author seems to think that after 5 years he can summarize the mistakes he has made in his programming career, somehow that suggests to me that either the career is now over or that there will be no more mistakes from now on

Whereas the 'exposure' the author has had to me would qualify this person as a trainee programmer, certainly not someone that can look back at a 'career' of any significance. Give it another 15 or 20 years and we'll talk. And if you still remember any of these (other than 'reinvent the wheel', which is in some ways the worst thing you can do except for those times when it is the best) then you haven't had much of a career :)

Best of luck, and I hope you will make many more mistakes, these are not on a 'I should blog about this' level yet.

They're more like introductory level mistakes that you could have for the most part avoided without too much work.

5 years is a long time for only 7 mistakes, I've been doing this for a while and I'm happy if I get through the day without at least double that figure ;)

to program: verb, telling a computer what you thought you meant.
And even better, the Crosby article on optimizing timing attacks. He gets to the level of measuring differences as small as 15-100 microseconds over the Internet and 100 nanoseconds over the LAN.

http://www.cs.rice.edu/~dwallach/pub/crosby-timing2009.pdf

I think there's still more room to improve on this paper by using more sophisticated modeling.
Ok, maybe BMI is not a good metric but I'm sure the administrator of the school can make the difference between 200lbs of muscles and 200lbs of fat.
With regards to being a passionate about hacking though, there's another problem: the pace of technological change. Take the guitar example: you invest a couple of years learning to play the guitar and perhaps develop a passion for it. That's something you can continue to nurture for a lifetime.

On the other hand, take the example from the article: the bored web developer spends "a few years" mastering Ruby on Rails. Oops, by then RoR is yesterday's news, now it's Clouds and Hadoop and Clojure and [insert technology/language/architecture du jour here]. So I think what you need to work on is not mastering something like "Ruby on Rails" but something at a higher level of abstraction... skills and habits that let you remain proficient and passionate about your craft even as the technological sands shift under you. I'm not sure how to really articulate what these are.
Can you elaborate more on how your sleep changed?

I don't have trouble getting to sleep if I put in a full day of productive work topped off with exercise. Is this product only for people with sleep problems?
Wow, you can store data and retrieve it. Why do we need web browsers at all -- Microsoft released Access decades ago!
BATNA - Best Alternative To Negotiated Agreement. If you subtly imply that you can walk away and buy elsewhere, then you can talk them down. You lose a bit of time, they lose their commission. If you know what their commission would be (or you can make an educated guess), you can talk them down a long way.

But if you behave as though you must buy there, they have no reason to drop the price.
>>The wristband tracks the movement of your wrist through the >>night, which it can use to analyze your sleep patterns.

How is wrist movement co-related to sleep patterns ? Is there any scientific study / data out there that explain the co-relation ?

Co-relation of pulse rhythm is more obvious - cant say the same about wrist movement.

Anyone care to explain ?
I've been evaluating all of these companies and I agree, Spreedly is the most startup-friendly. Not only in pricing, but they also have the broadest gateway support.

Unfortunately their admission that they may not be PCI compliant is a legal issue... if you read that, and pass cardholder information to them, you could be in breach of your merchant agreement and have no way to really know.

Spreedly also seems to be a side project that isn't getting the developer time it needs considering the sensitivity of what the product is. They have threads in their support area where they promised features a year ago and still haven't delivered.
OK, if you must have a specific item or service today, then your bargaining power is significantly reduced. Your BATNA (best alternative to a negotiated agreement) is to pay full price from the specific person you're talking to. If your seller detects that through your words or actions, you will always pay full price.

I'm saying that being able to walk away (even if you don't) is your most powerful piece of negotiating leverage. If you go into a negotiation without the ability to walk away, you're in a very weak position, indeed.
Holy Fucking Shit Yes

It took me about 15 seconds from the initial onload to typing my PayPal password, and I'm normally just seething with deliberative-yuppie-purchasing-angst. My normal minimum conversion time is at least an hour of research and a week of wall-clock time.

If you can hack my purchasing process so effectively, I'm pretty confident that you'll do well by my sleep cycle. Bravo!
You need your own merchant account to use Recurly or any of their competitors. They are not doing the processing for you. You have to provide them your payment gateway credentials, and they make the API calls to charge customers using your own gateway (and your own merchant account). They're only handling the technical side, none of your money ever touches theirs.
This seems brilliant. I've wanted to try the SleepTracker, but its a bulky, expensive watch and I never went for it. I'm pre-ordering this :)

Of all the recent YC announcements this is the first one that has me go: Yes! solve a real world problem. Runner up is the flight delay guys, but I no longer fly a lot for business so it is not as much of a factor as it used to be.

Congratulations, excellent idea and a very nicely priced implementation.

I sincerely hope you'll sell these by the containerload.
What is your blog worth?
Repositioning the KDE Brand
Recurly stores the payment information themselves, not through the gateway. I e-mailed them previously to ask about this. Theoretically this would mean that you can switch payment gateways and your subscriptions will continue to rebill automatically on the new gateway. It also means that if the company were to go out of business or you were to leave, they could potentially give you your customers' billing information to take elsewhere.
Expensive, though.
Mistakes, not experiences, are what makes us better programmers.
I think this is pretty significant advice. My daughter broke her foot one day before getting on a plane to Barcelona, where we planned on doing a lot of swimming, I had a waterproof cast cover over-nighted and they sent two. One for me and a free one for the foot doctor. The product worked so well, it literally saved our vacation and I couldn't say enough good things to the doctor when we got back. I'm sure giving the free sample to the doctor was a win for them, especially considering the doctor had never heard of the product.
This looks like the same technology used in the ubiquitous sleeptracker. http://www.sleeptracker.com/

I've heard complaints that it doesn't accurately monitor your sleep cycles because it uses an accelerometer which obviously doesn't work if you don't move enough.

There is a product called Zeo that supposedly detects your brainwaves but then people complain about having to wear a strap on your head. http://www.myzeo.com/

Anyone want to share their experience with these sleep aids?

Heh. I was going to post that I thought this was a fairly useless feature, certainly not on par with the impact of the other new stuff. But, I can't really say that it is a bad thing... I guess.
Sorry, when I wrote the comment I was on my Iphone and didn't check the website. I just did. I see what you mean. Why don't you just aggregate total click data and see which articles get clicked the most, bin the results to categories (5,4,3,2,1) by topic then compute Pearson? SVM still sounds a bit heavy weight. Sure, I guess it'll handle a few thousand...how about 1-10 million? And how do you know if SVM is the most accurate? What's your criteria?
The $4 million might seem more impressive were it not for Twitter having raised $155 million without a revenue plan.

Regardless, Milo looks like an interesting site. I could see it having particular value for people looking for popular toys this holiday season.
Not directly on the first-gen iPod Touch, since it doesn't have bluetooth, but the later ones do with OS 3.0 and up.

You could load the analytics app without it, but you'd need some device with bluetooth to trigger the alarm. Someone will inevitably release desktop apps to interface it, especially since all Macs ship with bluetooth and tiny USB dongles for your PC cost about a dollar.
I can't say there is any definite correlation, but Steve now believes in subjective reality and that his love is too big to be contained within a relationship, so think before you leap
The test is not whether you know the correct answer, but whether your brow furrows when you read the code. If you don't find the snippet interesting you fail.

The ultimate screen would be to follow the candidate home and see if they Google or test the answer.
Wow, compared to some other investments, Milo seems like gold in terms of monetization potential. Weird choice of criticism by pehub.
Free will is not why the KFC is relevant. It's relevant because it's not consistent with the reasoning they've put forward for requiring the class.
I never really thought about KDE as a brand, more as a bunch of software that happen to implement a desktop, of which I use only the taskbar, the calculator and 'konsole'.

The word 'community' is also not what's on my mind when I look at KDE, that is a very developer centric view of the world, to most people KDE really is a little 'k' logo on their taskbar and that's about it.

All the rest of the application level stuff could disappear from my system tomorrow and I probably would not miss it.

And I don't really care much about what it is called.

Brands are a requirement for commercial software, open source doesn't really need brands.

Imagine, GNU as a brand ? emacs ? gnome ? GCC ?

I loved it but my life didn't accommodate it. It was much easier on work days because I could sleep both ways on the train, one nap in the middle of the day, and then make it through family duties at night before I needed another nap. My wife didn't enjoy the scheduling difficulties on the weekend and it's not something you can switch on and off on short notice (takes about 5-7 days the first time and 2-3 days to start back up). There's a couch at my new job and I'm considering starting up again.

I was going to say cut-n-paste your blurb... [so you get keywords]

But then it occurred to me that maybe doing cut and paste from webpage A to webpage B is a missing feature.

I dont think microformats or frames answer this need well.

It seems the most basic feature of a web mashup, so why dont we see this as a trivial standard?

<div src=url id=div_id />

Ive used plone before as a companywide repo for project docs, but one feature I wanted was to do this for subsections of a page. This would have solved that problem.
There are plenty of solutions out there that solve this problem. Development platforms such as NOLOH, Echo, Cappuccino, GWT, to name a few.

I hope he doesn't try to solve this without taking a look at what's already out there.
I liked the highly motivational ending, if you lose, in Death Duel for the Sega Genesis:

Your defeat has brought chaos to the Federation. Your cowardice and betrayal shall be known throughout the stars. Your decaying corpse will be an object for ridicule and scorn. Disgrace will follow your family for centuries.

Once adorned and worshipped by all. Your rotting flesh will serve as a reminder of the price of failure.

Oh, the horrible pain of defeat....

Game Over
The lack of installation leads to another selling point of web apps. Security. Whenever I install something on my computer I instinctively flinch as I realize that I am handing over the keys to my car so to speak.
I've used the zeo for a while. Love it, but in the end I move the headband off my head in my sleep (active sleeper) and would wake up with no data 1/3 of the time. That is frustrating. From what I read this is true for about 10% of users.

As far as the Zeo goes, it is a great product. Very interesting future (there are some obvious 'this is a first release' flaws) but overall, it rocks. Knowing to the minute how much you slept with REM and deep sleep markers is quite interesting and fun.

I've got an extra in Boulder if anyone wants to try it out.
There is a professor at my university who is known for doing something like this. He says for every exam that if /no one/ writes anything on the exam, everyone in the class will get an A on the exam. But, if one person writes anything on the exam, then he will grade all the exams normally.

Apparently he's never had an entire class leave all their exams blank.
For those who want to play with data mining a little bit, here are some dataset from the past data mining contest: http://mill.ucsd.edu/index.php?page=Datasets&subpage=Dow....
I bought the Zeo a couple months back based on reading about here on HN.

What a huge difference in the morning! I used to be the kind of person that needed a 20 min hot shower to properly wake up. Now I wake up mostly alert and almost never groggy.

I noticed the change most this week since I flew to Philly for Thanksgiving with family and don't have my Zeo. The last few mornings without it have been hit or miss.

The pretty graphs and statistics were interesting for the first couple weeks, especially to compare how alcohol and caffeine affect my sleep, but the novelty wears off. The smart wakeup is by far the best feature and if the Wakemate can do a similar job, it'll be a cheaper solution that I can take on the road.

My first thought is that pricing should based on the number of followers;

0 - 999= $9/mo
1k-10k = $29/mo
10-20k = $39/mo
21-30k = $49/mo
31k-50k = $59/mo
51k-100k = $79/mo
100.01k-300k = $129/mo
300.01k-1mm = $259/mo

I totally understand the concept of not reinventing the wheel. Reminds me of the time when I was overjoyed at the fact that I figured out how to implement a flood filling (http://en.wikipedia.org/wiki/Flood_fill) algorithm and then the next day I found something 20 times faster on Wikipedia.
OK, but I think the suggested relationship between motion and e-motion is misleading. It is interesting poetically, but it is not particularly insightful or useful in an argument.
You're right--if the school is forcing some students to take that class to lose weight, and is forcing them to follow an exercise regime, it should also force them to eat healthily. But that logic only applies to the students being forced to take the class.

Managing temptation is a part of losing weight. I've been on a new diet and exercise program for about a month now, and while I did go to Burger King today, I made way better choices (a Whopper Jr with no mayo and chicken tenders with honey mustard (total: 560 calories)) than I would have before (Whopper with a medium Coke and medium fries (total: 1440 calories). My sodium, fat, and sugar were way higher than if I cooked myself, but the calories weren't that bad. Sometimes I just want something convenient, cheap, and tasty--diet or no diet.

Walking past a KFC every day, and even going in and eating something there, can be a pretty important tool. I've found it easier to modify my lifelong habits than I have to abandon them.

Why does CT corp charge startups $213.74 annually?
This is the company that YC recommends their companies use to incorporate in the state of delaware. I can't figure out what they do exactly but they send us a bill for $213.74 every year threatening that if we don't pay it this "may impact the company's authorization to do business. Please consider the legal consequences of CT's discontinuance."
If there are 40 YC companies a year and these guys make ~$200 off each one, they are getting $8000 from the pockets of YC companies for doing nothing! Can someone please tell me why we should have to pay these jokers?
This may be obvious, but how do I search GitHub as an employer? Do you just view a lot of different individual profiles?
