It isn't an activity. It's leisure. Leisure is cool. Friends suggest friends do leisure.

Hobbies are fine but sleep is a very good thing indeed.
And having three hobbies at once means low efficiency and mediocre results.

Take e.g. language. Odds are against you. You don't have people speaking that language around all the time. You're not surrounded by texts in that language. You do boring homework and it's like you're carrying water in a sieve.

I learned English by not learning it. I had to read various texts because that's how you program, surf the web and play games, and eventually I could read in English at the same speed as in my native tongue.
Recently I tried to learn Korean and it's now on hold. I had a half year of courses and some audio lessons, but I lack discipline and therefore my progress is zero.

As for history: if it's a map of dates to event descriptions then it's a pretty boring thing indeed, and if it's a mental model of how people lived NNN years ago then you can't build it by busy loop studying. You have to think, contemplate and compare a lot. Watching Rome series with your wife gets you more in your long term memory than a bookful of words and also helps your personal life.
They're struggling to compete both high and low. The iPad is pressuring them to put out a product that can use Amazon's VOD while BN is pressuring them to put out a device with a price that competes with the nook which has partnered with Netflix.

I doubt Netflix has any interest promoting either iTunes or Amazon services. It would be as stupid as Borders allowing Amazon to run their website. Hopefully this creates a nice trifecta of choice that benefits everyone.
Abstract algebra for developers and people who hate math
right, I was suggesting that the vendor (Apple, Amazon) of said products would undertake the testing cost.
Thanks for the feedback! Currently links are only shown chronologically. There's a tag mechanism that surfaces the links by topic. Agreed that it could get noisy - likely though that could be helped by allowing people to create their own custom pools of topics and people.
The Restoration of a Unique Film
I recall years ago sitting in the LAX UA red carpet club listening to a portable cd player (yup, long ago). My music cut out, and thru my cd player, that didn't even have a radio as I recall, I was listening to the pilot pulling into the gate outside the window communicating with the ground crews over his headset.

Now, as I understand it, that lovely FCC stamp on the back of our electronics means the device must accept any interference received since it's a consumer product... but I'd also hate for my pilots to unexpectedly get my co-passenger's latest dubstep mix opposed to the air traffic controller during takeoff.

For the record: I'm the guy that intentionally leaves his phone on, in airplane mode, idling. I think this is good enough.
Board Game Gift Guide 2011
Reminds me of a Southwest flight attendent on a recent flight: "The definition of 'turn off all electronic devices' is to 'turn off any device that is electronic'.
They would have to test every model of iphone against not only every model of commercial airliner in operation in the U.S. (including puddle-jumpers), but against every major variation in avionics suite among each model. This testing is not cheap. Even for Apple, it would be prohibitively expensive.
The keyboard is irritating and mostly pointless, but I do agree with you on the screen resolution. I used the smaller version with the keyboard and just wished the keyboard was replaced with a larger screen.
Tests are performed when inflight connectivity is added to a plane -- and it has resulted in finding interference issues, such as WiFi blanking avionics screens (http://www.flightglobal.com/news/articles/wi-fi-interference...).

For cellphones, there have been many reported incidents of interference when pilots had them on (search Google). I'd assume testing on cell phones would officially commence with installs of pico cells on US airliners.
It's basically like a hosted instance of Reddit, except without all the features that make Reddit great.
Both have the same inconveniences, but the iPad keys are bigger so it will always be better.

I find the iOS' problems with text editing don't really have much to do with its keyboard though. For instance, the "press, hold, move awkward magnifying bubble to relocate cursor" sequence is utterly boneheaded and they need something better; I don't mind occasionally typing the wrong key as long as I can quickly move the insertion point to make a correction and I can't.
This isn't true. There are several kinds of built in upgradeablility.

First, the relevant structures have version identifiers, so new clients could operate on a mixed network without problems (though with the new features disabled) and continue to parse old messages.

Secondly, all bitcoin transactions are governed by small programs written in the transactions (called scripts). Many of the scripting OP codes are 'reserved' and treated as NO-OP by the clients today. If a vulnerability was found in ECDSA and we needed to migrate off it fast— You could write transactions which require a (say) lamport signature PLUS an ECDSA signature.. and encode the lamport signature requirement in script as a NO-OP (e.g. one of the no-ops gets redefined a 'check lamport signature'). Old clients will ignore that requirement and consider the txn good if the ECC key was good, new clients will validate it. The network could run mixed for a long time, though transactions sent and received by old clients wouldn't enjoy the improved security.

The script mechanism doesn't let you upgrade everything, e.g. you can't change the hash used for the proof of work or merkle tree that way... but that aspect of the usage is the most robust against attack. E.g. Bitcoin would still be acceptably secure if MD5 were used in the POW as well studied functions tend to fail fairly slowly with attacks becoming more powerful gradually. For those things you're left with the alert... and even there the system can use indicators in coinbase to have mining nodes vote on when to activate the change.

Because no one mining would be left on the old network clients that didn't upgrade would just see transaction processing stop, not a significant split.
They just dont want to say it's ok then get sued to hell whenever a plane goes down.
In Russia there is also a widely popular among students and programmers neuroenhancing drug Phenotropil/Phenylpiracetam/Carphedon (http://en.wikipedia.org/wiki/Phenylpiracetam).

Unfortunately there are no research about safety of long term use.
It has been AFAIK on the test block chain. The test block chain has been intentionally forked many times to test this sort of behavior (orphan blocks).
The paragraph below really shows it, too. The premise is that money spent lobbying the government is an 'investment' that returns social services--but it ignores that the government first has to tax consumers to buy those social services in the first place, and the undesired effects of e.g. minimum wage laws.

"A coming study by the National Committee for Responsive Philanthropy, which advocates giving that aids the poor, looked at 100 social welfare organizations in 13 states. The groups spent about $230 million on advocacy and organizing for minimum wage laws, expanding tax credits for the working poor, and other programs. Those efforts, the study found, produced more than $26 billion in direct and indirect benefits to individuals, a “return on investment” of about 115 to one."

I always see this argument brought up (on HN), but what does the FAA care about cell carriers' networks? Why don't they ever use this justification when asked to justify their policy?
Most of them allow you to take the battery out if it comes to that.
I wouldn't call it a solution so much as a working approximation to a solution. AFAIK a complete solution would mean you could quantify how much each party trusts each other party at any given time.
UGGs Kensington Sale
Kensington Ugg Boots upper is plush leather fully lined with genuine sheepskin, has double buckle details and a signature UGG logo metal hardware on the heel. The insole is genuine sheepskin and the EVA outsole provides flexible comfort. Women's Ugg Kensington is a comfortable boot made for durability wear.
That costs money though. There's a reason that a good number of the planes in use are decades old.

I don't have an iPhone but I would choose that assuming the typing is comparable to other touch screen phones. I find typing on an iPad to be quite difficult due to it's size. The split keyboard helps, and it's bearable in portrait mode, but it's always hard to hold the device while trying to thumb type.
YES! It's a winning powerhouse.

Also consider that successful outcomes aren't distributed evenly; if you're exceptionally talented and work at an exceptionally good company, then it's not about odds, it's about execution. It's only gambling in the way a professional poker player gambles.
In order to argue that redis isn't a database you have to first define what a database is and explain why redis doesn't fit that definition. All the author did was assert that redis isn't a database and give 3 use cases.

This is just bad writing, to be blunt.

And for what it's worth antirez wrote an HN clone using redis as the database.
this entire debate would greatly benefit from tabooing the word "money" and talking more concretely about wealth.

So what comes after Haskell? After I had used Haskell for a couple of months and had got a few projects under my belt, it was time for a new step. I felt that my next logical step was a Lisp.

This strikes me as an odd "next step". I don't code in Haskell or clojure, but I've been eyeing both and the impression I got is that Haskell is harder to grasp but more powerful once fully grasped (and nearly as portable as C++). Sort of a superset of lisp. It seems that the next logical step after a couple of months of Haskell is more Haskell. It evidently worked out great for him, but I'd have liked to know why he switched to clojure.
> 1. Regex search support. 2. Browse full file. 3. Filter search to single project.

Regex search doesn't seem like a requirement here; for searching code, it usually suffices to include symbols when you index. Might also help to have some language-specific text classifiers, so you can say "search comments" or "search strings" or "search code".

Browsing the full file seems quite important to check the results. For that, you'll want line numbers, per-line anchors, and basic highlighting support for popular languages, in order of priority.

Filtering to a single project doesn't actually seem that helpful; if I know what project I want to search, I can clone it locally and grep it myself. Code search engines help with questions like "does anyone use this API?" or "how have other people processed the data from this library?", which need to search all projects. Filtering by language might help, though (to avoid problems with APIs provided in umpteen languages).
> If everyone has 15 objects out and is busily typing away, it's going to be tht much more difficult for flight attendants to get everyone's attention to give instructions, and crucially, much much more difficult to evacuate the plane as quickly as possible.

I'd imagine the screaming, flailing, flickering lights, smoke, and vibrations would do a decent job of getting people to look up from their iPhones.

> It's the same reason they aren't serving food and drinks at those times, and the same reason you have to stow your carry-ons and put your tray tables up at these times.

None of those restrictions are in place to make you listen to the attendants. They are in place because takeoff/landing is generally the part of the flight that is bumpiest and with the most maneuvering. Flight attendants (legitimately) don't want to clean soda off the ceiling or get hit by a suitcase.

It doesn't have wifi, unfortunately. I have a first-gen DX (and have had several of every model of Kindle since the first, actually), and am sort of considering upgrading/adding another one.

It is the best PDF viewing solution out there. If you read CS papers in PDF format, it's great.

Wifi and some way to keep in sync with a folder on my desktop (or in dropbox) would sell me completely. I don't want to pay Amazon every time I upload a PDF to the device via email.
had mine for 2+ years (got the second iteration the day it was released) and never knew this.
That characteristic GSM interference is actually quite harmless to most well designed systems. In some sense, the GSM buzz is more caused by bad design of the audio amplifier than anything else. Also it's mostly caused by nearfield magnetic effects in contrast to RF emissions. I think it's safe to say that this is completely irrelevant to most avionics systems (but nobody is going to guarantee that).

As an Amazon referrer, doesn't it mean they have to track you, too, until you make the sale? I thought they said there's no tracking whatsoever.
"Most people are deficient in a number of areas, and you can get screened for them all at once."

On a side note; Borders was powered by Amazon from 2001 through 2008, until they decided to go separate and compete directly with Amazon. Of course this only mattered until Borders merged with B&N in 2010.
"The Clojure Community and I"
So any of them actually have comparable specs? It's hard to believe given that Amazon is taking a loss on the hardware.
What an interesting web page.

However, there's a massive difference between instant release (IR) and extended release (XR) Adderall pills. The body is effective at downregulating pharmacological peaks as they happen, so IR is less effectively potent than XR. For example, for me, a 20mg XR lasts longer with greater effects than an entire 40mg IR pill rationed apart and taken within 4 hours.

I'd go as far as to recommend against IR amphetamine. The peaking of IR doses builds tolerance incredibly fast. I'd place XR amphetamine on a different plane entirely.

If anyone isn't having success with IR, I recommend XR.

Finally, prescription amphetamine is dirt cheap with insurance. I don't have script drug insurance and pay $160 for 30 pills of generic 20mg Adderall XR. With insurance, it's a mere $12 for a month's worth.
> After a 30-degree navigation error was corrected by turning off a DVD player, would the pilot seriously endanger the aircraft by asking the passenger to turn it on again to test?

No?

1. 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.

2. Pilots are extensively trained to deal with equipment failures, including total loss of power and instruments.
I don't think people are arguing against working hard, I think they're just pointing out the untold part of pg's wealth essay. Namely, you can work your butt off for that 4 years and still not make it. Sadly, that's a far more probable outcome than acquiring 40+ years of working income at the end of your 4 year stint.

Having said that, if you're young, dedicated and focussed and it interests you - hell, have a crack. But know what you're doing - startups are always a gamble.
If you're going to be a pedant, at least be indisputably correct in your pedantry.
If I have to do significant typing, I either wait or I use a Bluetooth keyboard.
Technically, yes, there is a "radio" in your TI-84. The Z-80 is clocked by a crystal oscillator, which runs at a few MHz. Some of that energy will escape in the form of electromagnetic radiation. Sensitive instruments (including an ordinary AM radio) can pick up this radiation from distances ranging from a few inches to several yards. This is true of essentially all modern electronics, although the frequencies have obviously gone higher and higher over time.

If it were true that the RF energy levels emitted by FCC Part 15-covered consumer electronics could interfere with aircraft systems, it would be utterly unthinkable to permit them on board in the first place, whether "powered off" or not. The TSA would be confiscating Game Boys, not bottles of water. Since that isn't happening, it's difficult to avoid the conclusion that the prohibition is just one more exercise in bureaucratic security theatre.
Here's a sincere informational question. Where is there a sound research base on any "nootropic" or "neuroenhancer" or "smart drug" or the like that has been subjected to thoughtful scientific examination

http://norvig.com/experiment-design.html

and has resulted in genuinely superior levels of human cognitive performance? I'm not talking about Wikipedia articles. (I'm a Wikipedian, and I know how many fudged references and commercial product-pushing there is on Wikipedia.) I'm talking about large-n, placebo-controlled, double-blind experimental studies that get published in a major, high-impact journal and pass muster with a process like Cochrane Review

http://www.cochrane.org/cochrane-reviews

or at least the joint blog Science-Based Medicine

http://www.sciencebasedmedicine.org/

or prominent mention in a major textbook or practitioner's handbook on pharmacology.

There is huge worldwide interest in people engaging in smarter behavior, but where is there the evidence that anyone really, truly becomes smarter at anything in a sustained way under the influence of any of the "smart drugs," "nootropics," or "neuroenhancers"?

I ask, because I have been reading claims for smart drugs in online communities since 1992, and I have yet to see any examples of especially smart behavior on the part of anyone making those claims. I have acquaintance with the behavior of highly smart young people,

http://cty.jhu.edu/set/

http://www.davidsongifted.org/

http://news.ycombinator.com/

so perhaps I know smart behavior when I see it, but I have not found, after diligent search, any reliable evidence that any drug intervention is more effective in bringing about smart behavior than drinking coffee. Where is the good quality evidence?

P.S. I just found the earlier submission, from the year of publication, to HN of this article:

No, the VCs were scared that they wouldn't earn a high return on investment with most of the money going to license fees, application fees, and surety bond premiums; and that in the alternative, they might be at risk of going to jail themselves. See 18 U.S.C 1960(a):

How is it better than iPad? I've long wanted large PDF viewer but only option DX was $$$ and b/w. I got iPad for unrelated reasons but fallen into using it for PDF reading. It's great. most my PDFs are image/graph/color intensive .5/11" non reflowable. I need to jump around lots rather than read cover to cover so page flip latency is kind of a killer.

Pretty good list, I was originally worried if it would be all complex games based on the site it was from.

Blokus is probably the cheapest one on the list, and easiest to find. Ticket to Ride/Settlers of Catan are all around great games (and getting known enough that enough people know how to play them).

In the other section, I can vouch for Dominion (and all it's expansions).

Overall board game geek is a great site to get new challenging (and tons of fun) games. A lot of places I've worked, the geeks had board game nights...
... Not really.

It's certainly more 'advanced' than any Lisp, including Clojure -- for the past few years (or decades now...), Haskell has been where new academic language research has been done. [1]

But that's just the problem. The fact is that Haskell is a research language standardized by a committee of academics without much experience or interest in real-world use. And it shows. Clojure, in contrast, is a language designed for practical purposes after years of experience from real-world use, mostly by one person, and while he's not as smart as the committee that designed Haskell, he has something committees rarely ever have. Taste.

In practice, I find Haskell beautiful. With Clojure I get things done.

[1] I'd be willing to say that today, if you are not fluent in Haskell, you are strictly not competent to design a new programming language. For the exact same reason you weren't competent to design new one without knowing Lisp from about the '80s through '00s -- unless you know Haskell, you are passing by most of the new inventions in programming languages done in past few decades simply because you have never heard of them, and don't even know you are missing them.
