How Could a $2 Pair of Eyeglasses be Made?
That's fair, but it's definitely not the most effective means. If a woman takes 5-10 minutes to apply make up each day, and if they decided to allocate that towards some other activity, the amount of time spent doing something more productive would add up very quickly. I personally find that it makes women less appealing as it's quite superficial, and a waste of time/money.
Then hack it to send a different IMEI or serial number. I wouldn't make a bet against hackers getting compatible software to run.
The wafer is the hard part.

That's why I suggested making glass first, it's a good primer on the kind of gear that might one day lead up to the tooling you'll need to make silicon pure enough to make a transistor.

You'd be much better off choosing a road that leads via relays, that's just metalworking and some coating. Vacuum tubes would still be an order of magnitude easier than silicon.

Think sandy beach + pit mine, before you turn that into a working transistor you're going to be busy for a while.
Dust, not sand. :)

I believe that NASA and aviation researchers developed fatigue tests some time ago. There's also discrimination-timing tests.

For example, if the object on the screen is a blue circle, press the right side shift; if it's a red square press left side. Reaction time is used as the indicator.

But these are only proxies for what is, after all, a largely subjective experience. You will necessarily need to rely on measuring inputs (hours of sleep, caffeine consumed, exercise length and intensity) and using subjective measures for outputs (a bit slow, tired, very tired, exhausted).
Sometimes I wonder if this is the only book on diet and exercise anyone on HN has ever read.

> Evaporation would leave the salt (and most other minerals)

That's a good point. I can't say I know the answer, but I've read/heard that drinking this mineral-free water can have long-term adverse health effects (leaches minerals from your body into the mineral free water?). I see articles for/against this theory. Interested to hear comments from anybody who actually knows details.

Of course dying from thirst or salt poisoning in a few days versus the long-term prospect of slow mineral loss make the choice a no-brainer in the case of an emergency.
I have not looked hard at these financials (nor do I have ANY experience with the cosmetic industry) but it appears Estee Lauder has a Gross Profit Margin of 79% in its most recent quarter. That is pretty incredible. Of course, this excludes advertising expense, but it does provide evidence of significant mark-ups on their products.
Part-time work at a grocery store for years, and years, and years... Some retail work is thrown into that time span as well. $8/hr is high-living! I was making $6.50/hr at The Fresh Market.
> That there is no one who you'd actually want to vote in to public office to replace the scoundrels that screw the people over and over again is another issue.

Ron Paul is running for President on a platform of drastically reducing the size of government and eliminating the Federal Reserve. He would definitely change things.

Lance!

Great execution on this site. Very simple and straight-forward. I was not confused or lost at any step in the process. I'm pretty happy with the business model as well. I'm guessing you make a commission on the offer made by the service providers that bid on my jobs?

Your website is clean and straight forward. No distractions. It would seem you're having a hard time getting service providers to give offers. I'm seeing a lot of views but few offers being made. You didn't really ask, but I'm assuming you have a way to target these individuals.

My only observation was that your heuristics for determining an appropriate category were pretty off. I did pick a task that didn't seem to fit anything appropriate, so I'm not sure if my case was more an exception than the norm. Otherwise, I really like everything about this flow and onboarding. I think you ask for just the right amount of information when it's needed and don't force the user to commit to anything too early. IMHO, great job!
> [1] This is database 101 stuff - a class I never took.

Yes, yes, a thousand times yes.

The best and most important way to improve database performance is to have a sensible schema. Query planners can do magic with stuff that's sensibly normalised and with things that are sensibly denormalised.

Where they choke is on schemata where everything is just squished into a bunch of tables with fields holding internal datastructures.
And here I was thinking this thing called DNA carried the information.

We have built out infrastructure to support about 50,000 users. Premature? Sure, but fairly reasonable for the price. Most of the server capacity consists of our Cassandra cluster which we are using to personalize user content...
Make-up itself costs very little to produce, so I suppose I could have just said mark up.

I'm not an equity expert, but I have the feeling that how that one specific company has performed over one quarter isn't a great indicator. They still had double digit EBITD margins last year, and I know L'Oreal had double digit margins for something like 20 years in a row.

Out of interest, do you personally think cosmetics make someone "beautiful"?
Of course he might not do it at all.

Where'd you get that data? The google finance page seems to state 7.99% not 79% in 2011. You sure you didn't misplace a decimal?
Why is this quote worth considering or insightful? What does it add to the discussion? Have you done half of those things? Did you really get anything out of it? Some insects specialize, some do not. One could just as easily say farming is for insects, or flying, or a multitude of other things. Just because several species of insects do something does not mean we should not.

This quote, along with a few others, seem to be always dropped into internet discussions with no context or explanation, and I never see them add to the discussion.
Show HN:  My iOS5 app using CoreImage and Twitter integration
It's so much data that any user of the app would have to have an iCloud paid plan, and it would also swamp any 3G usage plan on an iPad. Both of those would put a chill on sales.

Also, is iCloud secure enough for sensitive military charts? Maybe it is, but even so, explaining that to buyer is going to be a problem.

If Apple insists on this course of action, the eventual solution is probably vector maps. But a good vector mapping API doesn't exist for developers, doesn't work for many maps that only exist as rasters, and will take much R&D to make into a reasonable reality. In the meantime, I would hope that Apple chooses to unbreak the hundreds of popular mapping apps they broke last week.

If Apple insists on getting rid of the old behavior of the Caches folder, they need to deprecate it over the course of a year or so. None of us even figured out this would happen until after iOS5 went live, despite extensive testing from many devs. How this went live is beyond me.

I did I went to Mayo Clinic and NIH websites and the gist of it is too much water results in rapid loss of sodium and your body's cells swell up with excess water.

Drinking litres of pop such as low sodium would also be dangerous according to the descriptions given at those sites, so many people these days just drink pop and lots of it.

Any on-going health problems such as poor health in a person would increase the risk of a serious condition such as water intoxication.

It's probably why there is some sodium in bottled water.
I use to not eat breakfast everyday for 18+ years. it was something I just didn't do. It wasn't until 2 years ago that I started feeling the effects: chronic fatigue, I was always feeling lethargic, etc. eating breakfast changed everything (a healthy diet really).

Couldn't agree more on this, throw out your alarm clock, it's killing you. Remove stress from your life, take a shotgun to stress and refuse to accept stressful situations / people. I've lost 100 lbs in the last three years, here's how and how much weight I lost (I tend to have long plateaus).

I started on Nov 25, 2008: 285 lbs

Nov, 08: First Step, got Divorced:
Lost 10 lbs - 275 lbs

Jan, 09: Job tells me I have to be in at 9 am or will be fired.
Gained 10 lbs - back at 285

Mar, 09: Haven't really been in by 9am, hand in my resignation as part of the earlier agreement.
Lost 10 lbs - 275

Apr, 09: Job agrees that I can come in when I'm well-rested. Lost 10 lbs - 265

Aug, 09: Burning Man
Lost 15 lbs - 250

Sep, 09 - Jan '10: Start seriously cutting refined fructose
Lost 10 lbs - 240

Jun, 10 - The 30 people they hired to rewrite my code are finally done, I get fired. Lost 5 lbs - 235

This is the point at which I really start losing weight as I'm sleeping much more naturally

Jun, 10 - Mar, 11 - Sleeping completely naturally and start cooking all my meals
Lose 15 lbs - 220

Mar, 11 - Startup Bus - Having a blast helps!
Lost 10 lbs - 210

Jun - Jul, 11 - Spend two months in SF, eating mainly homemade veg tacos (walking more)
Lost 10 lbs - 200

Jul - Aug, 11 - Get back from SF, get an office downtown, start trying to get in by 9am.
Gain 10 lbs - 210

Aug, 11 - Now - Give up on 9am, walking more, eating a little more veg
Lost 20 lbs - 190

Pretty much everything that's led to weight loss for me has been all about enjoying life and cutting stress. Small improvements to diet and exercise as well but I don't go to the gym or stick to any sort of diet plan.
That's what I heard. Women will give up many things before they stop going to the salon.
I've become pretty harsh on video games in general. I wasted a lot of my life in WoW, and I've seen a couple other people waste their brilliant minds on video game playing.

If it doesn't contribute to interpersonal, personal, or societial good, I don't want to play it. I've gotten my 'video game' fix by playing pen and paper RPGs and meeting new people.

These days, I read history books for my "long-term amusement" and wouldn't mind playing video games with long-distance family (they don't play though).

Remember Steve Yegge's talk this summer. Please, do something more uplifting than incrementing a digital counter.
Ask on their forums?
"Eating your own dogfood" is nice and all, but why do we expect the top executives of a massive organization to actively participate and dictate every aspect of every facet of the company? That's the point of delegation; Google+'s lead developer _does_ use Google+, and that's what's most important.

Is anyone else baffled as to why people seem to care about this? For a parallel, what's Bill Gates' gamerscore? Does he even have an Xbox Live account? (If he does, please mention it.) For that matter, how often does the CEO of Johnson & Johnson douche himself? These are, apparently, the facts that matter.

Mandatory disclaimer: I have a Google+ account, but I've never once posted anything (I just wanted my name to appear in the header bar on my Google pages (yes, I'm vain)).
This is a good article and reflects my experiences reading the mailing lists and watching TGIFs as a Google intern.
Why would privacy be an issue? Unless people are collecting your tissue and sequencing your DNA without your permission, I see no privacy concerns.
What about computer engineering do you feel is messy? To me, it all comes down to basic physics, arranged rather elegantly.
I have a hard time with most "competitive" games (RTSs, fighters, FPSs, etc.) because people have a tendency to get a little too into them and sort of ruin them for more... I guess casual players? Like, I'm fine with playing a round or two of Generic Fighter X with my friends. What I'm not fine with is in-depth explanations of how to juggle and control vertical space while playing as Character Y. And I'm not saying this as a button-masher either -- I'm quite capable of learning combos and special moves and using them effectively. I'm just not willing to put the time into becoming crazy good at multiplayer games, which means I'll always be left in the dust by people who are willing to do so.

OK, I'll bite. :) I belong the camp which says Gmail's lack of encryption is "conspicuous".

Look at Ubuntu: they're constantly improving the user experience of encrypted home directories. In the latest release, this is as simple as checking a box during account creation (it creates the keys under the hood and uses your login password as the passphrase for the data key etc).

Also re: gmail has "no secure way". I read the white paper written by your company on the problems with encryption and javascript. AFAIK, if all traffic is exchanged only over SSL, I don't see any reason why encryption can't be done in Gmail in javascript (unless you're going invoke quality of the random number generators of browsers).

Here's an UX I can think of: (1) generate key pairs in the background in the browser for all gmail users. (2) transparently use this to encrypt to users within gmail.

Start from there. Then add the ability to import keys of contacts.
Ughh, the link is broken at the moment, stupid EC2 Elastic IP screwed up my instance and therefore my DNS. Here's a link to the app, http://bit.ly/spookify in the meantime...
There are a lot more costs than what it took to purchase the raw materials. It wasn't one specific quarter, it was simply the last quarter. And they were the first large cosmetics company I could think of.

I have no strong opinion on cosmetics either way, but it would be hypocritical for me to hate on someone for buying something with large profit margins. I'm typing this on a Macbook Pro attached to a 27" Cinema Display. Apple's margins last quarter? 25.58%. Their Return on average equity was a staggering 44.81%. Now that's fat.
This is Acmeism
I just recently suffered a terrific burnout at the end of the university semester. Forcing myself to take a couple of days off to just hit the painkillers and play Minecraft is one of the most sensible things I've done for my health in recent times.
Gross profit just counts cost of goods sold, not expenses like your employees. Cosmetics are high make up on a marginal basis, but involve lots of boots on the ground and advertising. Their Net Income is what you and I were talking about and is not outrageous at all.

(This is fairly similar to drug companies--very high marginal costs but in the end very normal profits.)
Just out of curiosity, what kind of video card is your MacBook running (integrated or discrete)?
This is why engineers aren't running fashion and beauty companies. It's not about efficiency. It may not make sense to you, but it very much does to a staggering number of people.
I wasn't hating, I'm a free market capitalist. I was suggesting it was contradictory of the protestor.
I love that the iphone and ipad are locked down. I gave ipads to family members and I'm finally done with tech support. My parents, girlfriend, and brother were bit by endless amounts of spyware, spam, and trojans because they used windows. I had to reinstall windows on my gf's laptop 3 times because adobe are useless worthless fuckwits who fill flash and pdf with security holes and her computer was repeatedly infected. Every time I went to my parents house I had to clean endless amounts of crap off their computer. My brother's laptop was infected with a virus that tried to get into bank accounts. He owns a pair of pizza stores and does his accounting on his laptop, and he accesses bank accounts with significant funds in them. Using ios fixed all the above.

While in theory it's nice that people can run any application they wish, in practice, it sucks. People end up having to be experts on computer security. As a group of computer professionals we've pounded on this for twenty years and it simply isn't fucking working. If telling people to be careful what programs they run or what websites they visit worked, it would have worked long ago.

Instead, I give them ipads for casual browsing and they're finally secure. My parents don't need my help to get pictures off their camera. There finally is a way for non experts to securely use the internet and applications -- just buy stuff from the app store. It won't spam you, it won't steal information, it won't install spyware, and it will most likely do what it claims to do. If not being able to run arbitrary apps is the price we pay... well, we tried doing it the other way for 20+ years and it didn't work.

The real question is, why nobody found yet species with 3 genders? I.e. 1 gender (cloning), 2 genders (sexual), ... 3 genders (hyper-sexual)?

3 genders will allow even more gene shuffling and multiple lineages to come together in a single individual.
I've spent my last two weekends on getting Gitolite and GitWeb set up and working well with other tools (cpan mini, Jenkins).

Besides putting it on hacker news, how do you plan to promote your app?
I've been using Siri as a utility and for entertainment for the past 48 hours.

It's incredibly useful especially when driving. I've plugged my iphone into my car stereo and have been using Siri to get directions, recommendations, play music and to compose messages. I'm able to get work done now while driving and Im doing so safely.

The success rate that she understands me (im not speaking into a ear/mic piece rather it's speaker phone like) is about 80%.

The only thing I have found to be a learning curve and source of frustration is composing messages. You really need to think of exactly what you want to say before speaking it. Also, you need to speak proper punctuation at the end of each sentence, like "Do you want to get food <question mark>" "We can meet at Applebees <period>".

This learning curve may turn some people off, though maybe others won't face a similar challenge? Either way I have found Siri to be enjoyably useful!
And to tie it all in, this is why Steve Jobs was such a visionary, because he understood both engineering and aesthetics, function and form. A lot of people understand one or the other, it's the rare person who can empathize with the necessity of both.
> I just found out yesterday how much money we are spending.

This strikes me as a stunningly stupid thing for a _CEO_ to admit to in public, and should give any potential investors pause.

Exactly. If the state of the world is that people can separately come up with the same "trade secrets", then there is a case against it being patentable.

What cash flow? They have 300ish users of a free product. Surely that isn't a huge revenue stream. I suspect it is just living relatively cheap.
Three inspiring videos (and three additional lessons)
Honestly, it was just a fun project that let me experiment with the new CoreImage API's, but also make something fun, polished and worth a buck. With the new camera in the iPhone4S and everyone upgrading to iOS5, the photo apps are going to explode.
Maybe I'm just biased because of my curriculum, but I didn't find this article informative at all. I actually found it overly dumbed-down. Perhaps it was meant for people with zero biology/chemistry knowledge.

bravo
any theory of sex is incomplete until it addresses why there are 2 sexes (even if one organizm can carry both sexual organs it is still 2 distinct sexes). It may seems obvious, yet a science theory must address it scientifically. All the shuffling, flushing, etc.. of genes would also work in 3, 4, ... sexes schemas. It will have different statistical distributions and the theory must prove that whatever goal of sex existence, it is somehow optimal with 2.
Why would it be called the five when it would be the sixth one? The four wasn't the third one.

Awesome writeup, thanks!

Came across something similar a couple of days ago while browsing the source code of Marathon (one of the early games of Jason Jones and Bungie, later of Halo fame). At the time, Bungie were the Mac equivalent of id software, and Jason Jones the equivalent of John Carmack.

(look for isqrt())

There's a great explanation in the comments.

This code was most likely written by Jason, probably around '93-'94.
