I know that chess is probably the most traditional "thinking" game to play in the western world, but when I read this line:

> I think there may be a lot of neat similarities to chess and entrepreneurship, but ultimately chess is too controlled.

...I felt compelled to mention Go. In general, Go is much less constrained than Chess. The strategy plays on many axes: not only offense vs defense (as chess) but also territory guarding vs invasion, speed vs strength, and risk-taking vs conservative-waiting. In general, I would say Go has many more parallels with business (and life in general). I've recently been turning my passing interest in Go into a full-blown obsession, and I would highly recommend it to anyone looking for an alternative to Chess.

I know all this. I also know that people will forget to turn their phones off, will have phones and laptops and all manner of devices in checked luggage that are possibly left on, and that these signals are all around the plane anyway.

If there were any credible threat from leaving your phone on, or having it actively transmitting, then ALL phones would be outright banned from the plane. Otherwise, a group of terrorists could take down a plane simply by passively not turning their phones off? When you look at all of the other TSA security theater bullshit, it's a safe conclusion (IMO) that the RF from your phone will not interfere with the operation of the plane, based on the simple fact that they are not banned in the first place.

Not to mention, I think that if this were even a moderate concern it would be easy to equip the flight attendants with an RF monitoring device they could walk down the aisle with and detect close-proximity transmitters from cell phones.

On modern flights where coach seats have been spaced at the minimum allowable level and people are forced to bring everything as carry on to avoid bagge fees you see far more safety threats from under-seat luggage sticking out into the seating aisle, potentially inhibiting safe exit of the plane in an actual emergency.

Perhaps eliminating restrictions on electronics use would have a similar effect. What if the FAA started out by allowing use on a select number of flights where the pilots were highly trained and aware of the supposed risks? Over time, restrictions could be lifted more broadly presuming these initial experiments showed no cause for concern.

In another, more macabre calculus:

= equivalent of 4566 deaths

which is more deaths than caused by 9/11. Every year.

Only because you don't have the time to do all of them justice. But imagine if you could create the time.

Sleep is only important in our present state - if there was a way to remove the need for sleep, then it becomes pretty pointless. I would very willingly remove the need to sleep - it's not as if I derive some kind of enjoyment from it besides feeling rested. If I can be rested and ready-to-go without sleep, all the better.

Yes, and how much extra contemplation, research, and comparison can you achieve if you took your 7-8 hours of sleep each night and dedicated them to study? What if, instead of going to work in the day time, you work during the night and spend your days going out there and doing feet-on-ground research on a historical topic?

As a coder, the prospect of removing sleep entirely is extremely tantalizing. Much of my work can be done in the middle of the night, and having days completely free opens up limitless opportunities for personal growth.

This is a fairly hot topic among most frequent fliers. Did you ever consider that column was more propaganda warfare from the FAA instead of actual data?
There were 769.6 Million passengers carried in 2009 in the USA (domestic and international). If each loses 30 mins of productive time on a plane because they can't use e-books or devices below 10,000 ft, that's 384,800,000 hours per year lost. Not everyone is working or learning something on a plane, but it puts things into perspective.

They don't use this justification exactly because they mostly don't care about that. It's interesting that there probably is no regulation that forbids usage of cell phones at high speeds and high altitudes (as opposed to "on board of a plane"). At least ETSI specifications seems to imply that it's perfectly legal to operate whole GSM network on board of plane, while hinting at fact that direct communication with basestation on ground from plane is not intended mode of operation and probably will not work. On the other hand there seems to be an large amount of anecdotal evidence, that it really does work, although with marginal call quality.

So conclusion might be something along the lines of "it's not designed to do that", which seems like pretty good justification when you are talking about airplane safety.

Have you ever had your phone switched on while on a plane? I have, more than once. Above about 8,000 feet it tends to be almost impossible to get a signal anyway.

Most cell towers have a lot of RF engineering put into them to direct the signals DOWN, not UP.
It was pointed out to me, years ago, that this is an FCC regulation not an FAA regulation, the reason given being that cellphones in the air can/do lock onto many more towers than on the ground (due to the inverse square law), and the network control protocols & software are (or were) not robust against this.
Quantum mechanics, statistical thermodynamics, and the ergodic theory preclude the possibility of water "remembering" a molecule which was present previously but is no longer in solution.

Standards for airborne electronics are actually even more stringent - FCC rules say in essence that your device may not produce interference and don't exactly care about whether you device works when exposed to interference. This is not exactly what you want in safety critical system. On the other hand, it's not about designing interference resilient system, but about testing that such system really works as intended, which would probably involve impractical number of tested combinations of devices (ie. consumer phones and whatever else). It's mostly about manufacturer's liability than anything else - it's cheaper to say "not supported and not tested".
There are plenty of studies showing "genuinely superior levels of human cognitive performance". However it is unclear how well these tests ("microbenchmarks" if you will) correspond with "smart behavior". It is difficult to imagine how improvements to short-term memory span, visual memory, spatial planning etc would cause a decrease in "smart behaviour", though.

Having said that, here are a couple of studies I've posted elsewhere on this story (ironically in rely to another similar comment by you, which you seem to have missed?):

Modafinil produced a similar pattern of cognitive enhancement to that observed in healthy adults, with improvements on tests of short-term memory span, visual memory, spatial planning, and stop-signal motor inhibition. On several measures, increased accuracy was accompanied by slowed response latency. This alteration in the speed-accuracy trade-off may indicate that modafinil increases the ability to "reflect" on problems coupled with decreased impulsive responding. Improvements were also seen in sustained attention, which was unaffected in healthy subjects.

http://www.ncbi.nlm.nih.gov/pubmed/15121488

Modafinil significantly enhanced performance on tests of digit span, visual pattern recognition memory, spatial planning and stop-signal reaction time. These performance improvements were complemented by a slowing in latency on three tests: delayed matching to sample, a decision-making task and the spatial planning task. Subjects reported feeling more alert, attentive and energetic on drug. The effects were not clearly dose dependent, except for those seen with the stop-signal paradigm. In contrast to previous findings with methylphenidate, there were no significant effects of drug on spatial memory span, spatial working memory, rapid visual information processing or attentional set-shifting. Additionally, no effects on paired associates learning were identified.

I'm not sure the reasoning follows:

1. "it's not designed to do that" refers to cell-to-ground communication, nothing to do with the safety of the plane.

2. cell-to-ground communications issues only apply to cellphones, but the FAA policy applies to all electronics.
I'm curious why you would use Redis instead of just using in-memory datastructures in your app servers? It's trivially easy to implement a leaderboard as a priority queue, for example. And it eliminates the need to run yet another server and deal with the associated RPC & command parsing overhead.

That's the approach Hacker News and Viaweb took, along with Mailinator and probably several other startups.
however, once it's on all new browsers there's no advantage; there's incentive for others to use it, which they will if it's advantageous.

You Guys Are Millionaires Right?
It’s quite obnoxious that billionaires are given such deference in our society to make policy decisions about topics entirely unrelated to their area of competence. There is little reason to believe that tech billionaires should be experts on education, for instance (as compared to say teachers or child psychologists), but because as a society we’ve made it difficult to raise money through taxes, we’re now uncritically embracing their educational reforms because they come with money attached.

The problem with forming public policy around the whims of the super wealthy, beyond their lack of special expertise, is that they are not accountable to everyone else in anything like the same way government is, and we can’t expect them to have interests closely aligned with the general social interest. Which means that as inequality continues to increase and the rich more and more attempt to provide public services as private enterprises, the ability for the rest of us to influence and “buy in to” these systems is steadily eroded.

The cash can be quite helpful in particular areas, but ultimately this form of policymaking undercuts democracy.

How about this? http://searchco.de/ (I'm not affiliated)
Let's presume for a moment that some sort of interference which could be generated by a box the size of a laptop might have a non-trivial risk to passenger safety. Now, think as a terrorist might. How about sending your minions onto planes with devices which look like standard consumer electronics devices but are capable of generating high levels of interference? Around the holidays in the US, someone checking or carrying on what appears to be an A/V receiver in a box would not raise suspicion -- just a gift for a relative. Now, inside that "receiver" is a battery and a transmitter (I'm not an electrical engineering sort of guy, so substitute the appropriate components) which emits what signals the terrorists hope will interfere with onboard avionics. Via a remote switch, the terrorist turns on the device during take-off and landing. If the plane crashes, is forced to make multiple attempts at a landing, etc., then the terrorists know they're onto something. They will refine their techniques until they can make plans fall out of the sky. If not, they try other experiments -- different frequencies, etc. Could such experiments even be carried out through transmitters on vans which could be temporarily parked on highways near airports? What if the terrorists could purchase airplane components with which to conduct their own testing and refine their "weapons"? Surely such an avenue of attack, if feasible, would be less effort than training your minions to fly an airplane, even if learning to land was not required? That no known terrorist attacks via this vector have been reported suggests it implausible. A problem with most terrorism "experiments" is that, if the experiment fails, the experimenter ends up imprisoned and thus incapable of further experimentation. Given the obvious recruiting issues the likely outcomes of either imprisonment or death present, terrorists ought to take like ducks to water toward techniques which allow repeated experimentation and refinement. That no incidents have been reported due to avionics malfunction suggests the near impossibility of actual passenger risk. QED?
Policy-making anythings are annoying. Let's see more policy-removing. Less fragile and less systemically harmful.
The times I've used it, they turn off the in-flight Wifi at the same time all the other electronics are supposed to be turned off. So that seems consistent to me.

The art of relaxing
When I looked into the topic years ago, ISTR finding a few FAA incident reports that did involve consumer electronics causing harmful interference with cockpit navigation systems. They didn't result in accidents but seemed well documented.

Did you come across anything like that?
I don't buy it. Ostensibly, this is a commercial flight where lives are at stake, so I strongly doubt that absent FAA direction the pilot requested this test.

It was already demonstrated that turning it off fixed it. If you see the instruments goof up again, you tell the guy to turn the player back off.

It's unclear from the account whether this was an instrument error or an actual flight path deviation. The latter being a more serious and unpredictable error. Who in their right mind would want to repro this given the unknowns?

Pilots are extensively trained to deal with equipment failures, including total loss of power and instruments.

Pilots also operate in an environment of substantial regulation where I'm sure a policy exists for investigation of operational interference. I suspect this policy is in line with the FAA's stance that "avoidable interference is unacceptable" and certainly this incident describes an avoidable interference.

I don't see any reason to retract my position that this story is likely a myth.

EDIT: My position depends on a number of assumptions that may be faulty: that this incident took place in the USA, within the last decade, on a plane operated by a significant carrier.
My favorite section is where he gives the context of how abstract algebra came about in the 19th century. It connects the theoretical with real world problem, which makes it far more interesting.
OP here. I love GO. For those that haven't played, it's the game showed briefly in a beautiful mind. Where Nash, the rational mind, can't figure out how he could have lost...and exclaims 'The game is flawed'

It's Othello squared. It's a fabulous game. It's intuitive, instead of rational. I lived in Japan for a year after college and played every year. It's hard to find people in the states that play and it takes a long time to play. The old saying goes, 'Two men sat down for a game of Go. That was yesterday'

If anyone plays Go and is in San Francisco, hit me up by email--would love to play!

Is it considered (un)professional to use an alias?
Hey guys,

Just a question from someone who is both a recent college graduate and just (seriously) getting involved in online activities.

Is it considered unprofessional to use an alias? If it's not, in what circumstances would it be?

For example, if you received a resume, would you frown upon it containing the e-mail something@randomalias.com vs. something@firstnamelastname.com, or similar?

Thanks for your input, guys.
