edj··on Kindergarten Teacher Earns $700,000 by Selling Lesson Plans Online
I don't think this is illegal, but many (most?) public school districts forbid their teachers from doing this.

In private schools, on the other hand, the practice is common. My 9th grade math teacher taught an after school SAT prep class, for example.

edj··on ‘Pink Slime’ Furor Means Disaster for U.S. Meat Innovator
As a little bit of an aside, does anyone else find it infuriating when articles like this are thick with links that don't lead to the destinations you'd expect?

For example, about halfway through this article there's mention of a prize-winning New York Times article that popularized the phrase "pink slime". I'd like to read the article, so I clicked on the link... and got a stock ticker quote for [NYT]. I get that Bloomberg is in the financial news business, but come on! There's no footnote with the actual link and not even a title for me to search with. It's just bizarre.

edj··on AT&T will unlock your iPhone for free starting tomorrow
I don't dispute your experience; I can only speak from mine.

I had T-Mobile from around 2003 or 2004 to August 2010. Every time I got a new phone (always subsidized with a new contract) I called immediately to ask them to unlock it so I could travel more easily. Each time they told me I had to wait 90 days. So I'd wait 90 days, call back, and then they'd send me the unlock code. Never had a problem.

edj··on AT&T will unlock your iPhone for free starting tomorrow
It's strict in comparison to other carriers. T-Mobile, for example, has long had a policy of unlocking phones after the first 90 days of the two year contract.

It's not exactly common sense either. If you unlock your phone, you could theoretically use it with another carrier, but you're still on the hook with AT&T for the full two year contract. Since they get there money from the contract regardless, why should the contract and unlocking have anything to do with one another?

Both the old policy and the new policy are bad for customers with (slightly) unusual use cases, like travelers.

When I had T-Mobile, I could buy cheap SIM cards in any country I went to, and put them in my Blackberry. I had all my contacts. I had one charger and one device. Now when I travel I have to buy a cheap feature phone for calls, but I also need to keep the iPhone around as a very expensive and conspicuous Rolodex. It's definitely a step backward in convenience.

edj··on A Burger, an Order of Fries, and Your Credit Card Number
I think the parent was talking about the US, where liability depends on how fast you report the theft of your card or notice fraudulent transactions in your statement. If you don't catch these quick enough then your liability is unlimited.

edj··on Stop whining and start hiring remote workers
I don't have much experience with managers because I freelance now and I've never worked at a company with more than about 80 or 100 people.

So this is a real question and not snark... Assuming large companies continue to exist, how do you run one without managers?

If your company is 1000 people do have 10 executives and 990 engineers, customer support, etc. and no managers at all? How does everyone communicate? How do the executives delegate?

Do you need some managers? How many per worker is optimal?

It seems like every large corporation in existence has managers. I can't think of any exceptions. So I'm not sure what an alternative would even look like. Perhaps rotating temporary management structured like jury duty?

I'll probably be downvoted because bashing management is a time honored hacker pastime... But I really am curious. Is it possible to do away with management? Is it desirable?

edj··on Feds want nationwide ban on cell phone use in cars
It sounds like they looked at the research instead of the not terribly well thought out state laws. E.g.:

This research examined the effects of hands-free cell phone conversations on simulated driving. The authors found that these conversations impaired driver's reactions to vehicles braking in front of them. The authors assessed whether this impairment could be attributed to a withdrawal of attention from the visual scene, yielding a form of inattention blindness.

Cell phone-induced failures of visual attention during simulated driving. Strayer, David L.; Drews, Frank A.; Johnston, William A. Journal of Experimental Psychology: Applied, Vol 9(1), Mar 2003, 23-32.

http://psycnet.apa.org/journals/xap/9/1/23/

and:

Summary: We used a high-fidelity driving simulator to compare the performance of cell-phone drivers with drivers who were legally intoxicated from ethanol. When drivers were conversing on either a hand-held or hands-free cell-phone, their reactions were sluggish and they attempted to compensate by driving slower and increasing the following distance from the vehicle immediately in front of them. By contrast, when drivers were legally intoxicated they exhibited a more aggressive driving style, following closer to the vehicle immediately in front of them and applying more force while braking. When controlling for driving difficulty and time on task, cell-phone drivers exhibited greater impairment than intoxicated drivers.

>(What if, in the USA, you download the file coding for the magazine and expand it to hold 30 rounds?)

The assault weapon ban--the federal law banning (among other things) magazines that can hold more than 10 rounds--sunset in 2004. Thirty-round magazines are perfectly legal once again, except in a few states, like California, with their own assault weapon bans.

edj··on The $700 Million Yogurt Startup
It sounds like Ulukaya is the technical founder:

"I came from a family of farmers who made cheese and yogurt..."

His dad was urging him to make cheese as early as 1998, and he did in fact start doing that a few years later.

1. Google and the other big boyz talk a big game about doing no evil, but giving out huge salaries and signing bonuses to attract the best talent is just plain evil from my vantage-point.

It's true there are no end-to-end 100% drive-by-wire cars. But there are certain drive-by-wire systems in many modern cars. Electronic throttle control[1] is widespread (or universal?) and brake-by-wire[2] is already used by Mercedes and Toyota.

edj··on Navy Sets World Record With Rail Gun
There appears to be potential. A quick google search turned up 'Launch to Space With an Electromagnetic Railgun' in IEEE Transactions on Magnetics. [1]

"The extension of this technology [rail guns] to the muzzle velocities ( 7500 m/s) and energies ( 10 GJ) needed for the direct launch of payloads into orbit is very challenging, but may not be impossible."

edj··on Ask HN: What to do in Portland?
Regarding coffee: albina press is good but has been surpassed. Most of the original crew left to start their own shops.

Red E on N Killingsworth is my favorite. Barista, in the Pearl and also on NE Alberta, is similar and somewhat more famous. Both serve Coava a local roaster that sells single origin coffees, meaning the beans are of one type and come from one farm. Their stuff consistently wins awards in the coffee world.

edj··on Ask HN: What to do in Portland?
+1 for pok pok, although I like whiskey soda lounge more. Across the street, same owners, similar menu, excellent whiskey and scotch selection, and authentic (i.e. no ketchup) pad Thai.

Regarding the gorge: some hikes are fine on weekends. Eagle Creek Falls trail requires a $5 per car day use fee, which keeps out the crowds. It's one of the best trails in the gorge. Skip it if you don't like heights though, and be careful if it's raining.

Japanese Garden is great. Worth the $8. It's in Washington Park which is accessible via public transit. Forest Park is adjacent. Good hiking, as long as you don't mind a little mud.

edj··on Ask HN: tips for working with Mac OS X without using the mouse? (RSI)
There's a lot of excellent advice here. Beyond keyboard shortcuts, there's a universe of options to help combat RSI. Here are some of the things I do:

1) Posture. You want your eyes to be on the same plane as your screen so your back and neck are straight. You want your elbows to be be bent at around a 90-degree angle--that helps keep your wrists straight. And you want your shoulders to be relaxed, not hunched.

2) Breaks. Both long and short. I used to use software for this, specifically AntiRSI for Mac. I think I did an 8 minute break every 52 minutes and a 30 second break 5 minutes or so. Now that I've built up better habits I don't use this software anymore.

3) A good chair. My favorite is the Swopper. It's quite expensive, though--around $600 I think. Right now I have standing desk and no chair. I like this set up even better than sitting on an ergonomic chair.

4) A good keyboard. I like "clicky" keyboards in the vein of the old IBM Model M. I use a DAS Keyboard. Costs around $100. It's not ergonomic per se, but the mechanical keyswitches provide great feedback so you can reduce your keystroke pressure to just the right level.

5) Physical therapy aids. I use Theraputty during my microbreaks. It's like silly putty, only it comes in various levels of resistance. I like green, which is medium-firm. Costs like $5 on Amazon. Some people also use the colored rubber bands, but that's more for elbow and shoulder work and my RSI is all in the wrist/hand.

6) Other activities. Rock climbing has very nearly cured my RSI. When I climb regularly my hands, wrists, and forearms are strong enough that keyboarding can't touch them.

I suspect fighting RSI is like fighting obesity (though I only have the former so I can't be sure): it's all about building good habits. There's no magic bullet and you can't simply cure it and be done. It's an always on-going process. Hope this helps. Good luck!

edj··on Why are so many people in their 20s taking so long to grow up?
"The median age at first marriage in the early 1970s, when the baby boomers were young, was 21 for women and 23 for men; by 2009 it had climbed to 26 for women and 28 for men, five years in a little more than a generation."

They've cherry-picked the trough of median age at first marriage in the modern era. Looking back a little farther shows that for men first marriage only dipped into the early 20s during a few decades in the middle of the 20th century. For women first marriage has been steadily rising, however.

edj··on Barefoot shoes try to outrace the black market
I've tried bouldering in a borrowed pair. Edging gets painful fast. Far too much stress on my toes. Having separated toes and a relatively pliable sole produces an awful lot of foot strain.

Real climbing shoes are tighter and more rigid. They do just the opposite of what these barefoot shoes do; they bunch your toes together, forming them into a kind of single supertoe. It's probably about as bad for you as wearing high-heels, but it's very effective.

Also, the soles on barefoot shoes are not sticky enough for climbing, so smearing doesn't work too well.

edj··on Burning man defeats PayPal
Reading this thread made me a little paranoid. So I logged into my high school reunion account (I'm the organizer) to withdraw the funds into our bank account, and lo!, of course there's a hold on one classmate's payment. That's $75 we may never see... at least not in time to pay our caterers and such.
edj··on Ask HN: Good Aeron knock-off/alternative?
Another option is the Swopper chair. http://www.amazon.com/A-801-Black-Swopper-Chair/dp/B00079EH3...

It looks like a barstool and feels a bit like a high-tech, firm, adjustable exercise ball. Easily my favorite office chair and vastly better, in my opinion, than Aerons.
