I've taken adderall on and off for 7 years, and I'm 27. In my opinion, ADHD is often a fuzzy diagnosis, but I would say that I'm legitimately classified as someone with mild ADHD. Many of my closest friends have also been people with ADHD, and we've talked a lot amongst ourselves over the years about the effects of the drug. I've noticed a lot of patterns, and determined my own set of best practices:

- Take your adderall in the morning. If you take adderall later in the day, it can affect your sleep schedule. If you don't sleep well, you may find yourself wanting to take more adderall to compensate for your lack of sleep the next day, and so begins a snowball effect that inevitably ends with a crash, and a net a loss of productivity.

- Extended release works better for me, and it has much less addictive potential than "instant release."

- Determine your personal minimum effective dose. Don't trust what the doctor happens to prescribe you to be the precisely perfect dose for you. There is most certainly a point of diminishing returns for net productivity gains. Higher doses have higher side effects.

- There are social consequences. If you'll allow me a moment of hippie speak, I'd say that adderall makes your mind resonate at a different frequency than that of regular humans. It's not so easy to establish rapport when you're not even operating on the same frequency.

- Long-term productivity gains for what I'll call production tasks is questionable. For boring work that just needs to get done, suck it up and just do it. Learn the Pomodoro technique, and improve your general capacity to focus by practicing meditation (if you have mild ADHD like me - I can't speak for people who have moderate or severe ADHD).

- Adderall works for me as an excellent tool for expanding production capability. If you have a repetitive business task that you can potentially automate, adderall works very well to help you think through automating it.

Due to the social side effects and my dislike for the inevitable down cycles (end of the day or off days) associated with regular use, I currently limit myself to use once a week. I use it ONLY to organize my week ahead of time, and to increase my production capability (learned this phrasing from Stephen Covey) by automating repetitive tasks. This is the system I've settled on after 7 years of trying different routines.

I could really say a lot more my experience with this drug, but alas I'm not on it right now :) If anyone has more questions I'm happy to follow up.
This is my today's best Hackernews item, ever. As a Videographer, I've always yearned for better DSLR's that can shoot video under (extreme) low-light conditions. I just hope they launch a consumer/pro-sumer model with this sensor soon! Throw in a low-light lens and you're all set for (ultra) low-light videography!!
The problem I had with the article was that it said what user accounts he set up, how their security was based, etc. Why!? Don't give away that info in a blog post! Even if it is something a hacker could easily find out if they wanted, by doing that, you paint a target on your back.

If you are walking past a dark alley in a big city, you don't say, "I am a blue-belt in karate, and I have a wallet with $300 in it." They have a gun, and they'll take that wallet, thank you.

I totally appreciate you putting all those links together, but I would hope that others remember that loose lips sink ships when it comes to security. And from a hacker's perspective, what's the fun in social engineering if someone just blabs it all in a post?
> The federal government underwent a massive expansion over the course of the 20th century. You're limiting yourself to the period following its expansion and then claiming it hasn't expanded very much since then.

I'm using the period since 1960-1970 because the character of the economy hasn't changed very much since then. Yes, the federal government was a lot smaller in say 1900, but at that time 40% of the population lived on a farm, versus almost nobody today. The appropriate size and scope of government for an agrarian society is not the same as for a burgeoning industrial society is not the same as for a mature service-oriented society.

> Privatizing the inefficiency doesn't make it go away.

Complaining that the government is big and that the government has inefficient policies are two separate complaints. The fact is that once you take out parts of the government budget that are simply taking in checks from one group of people and getting them to another group of people, government expenditures have actually been shrinking relative to GDP. Now, income redistribution may be a problem, but I'd argue it's a separate problem to "government is too big."

> Local programs have greater accountability and can be better tailored to the different needs of local populations.

This is a theoretical trope that is almost wholly not bourne out by actual facts. In practice what happens is that there is far less attention paid to local politics, which means that local government programs can get extremely dysfunctional before anybody starts paying attention. There is pretty much not a single state government that's as well-run as the federal government (except e.g. VA and MD, but its easy to be well-run when you're massively subsidized by the defense budget). A lot of that is due to the fact that state governments get far less scrutiny.

> the cost of such things is born by a more concentrated set of taxpayers who are consequently more likely to demand accountability and shut down wasteful programs

C.f. San Francisco.

> "It is one of the happy incidents of the federal system that a single courageous state may, if its citizens choose, serve as a laboratory; and try novel social and economic experiments without risk to the rest of the country." -Louis Brandeis

Yet the history of federalism has been that the only experiments states are interested in running are how to suppress minority groups and women.

I read the performance analysis comparing it to Go, Erlang etc. Has any comparison been made with Akka (http://akka.io)? How much would this extra efficiency matter when the communicating processes are on different machines? Since speed in communicating between local processes is important to you guys, I am assuming that the actor model is then used for all local and remote communication?
Have you thought about treating it as more of an agent query and bringing the user back to the site with an email notification? The searches I tried were so slow I'd probably forget about them and my stale-tab-killer would close them before I'd see the result.

Plus then you could potentially update them if better results came along (and they agreed to that).

I'd probably try an epoll based reverse proxy like nginx sitting in front of my application, which I'd then aggressively test. I'd download large ion cannon or whatever the kiddies are using these days.

I was under the gun for some client facing deadline and I had a crash so I had to rebuild my system. We had registration for our software and nobody was around to give me a key, so I commented out the authentication and call home (not normally in my part of the source tree) then promptly finished my work and committed the whole thing... got caught at the last round of QA fortunately.
Can you be more specific about the time frame you're thinking about? Adderall has been widely available since the 1940s.
> where would my refund money come from?

Almost sounds like you're confusing escrow with insurance?

Your refund would come from the middle guy entrusted to securing your funds until your goods were delivered as promised. If your goods are not delivered, or if what you ordered was nothing like what was promised, the escrow service would simply send your bitcoins back to you, instead of sending them to the merchant who tried to defraud you.

These services would likely charge a transaction fee for the service.

Even silk road offers an escrow service that is apparently effective enough. The scammers on silk road typically try to con you into closing the transaction before delivery of any goods, so one red flag that you may be looking at a scammer is a number of early settled transactions in their history.

If someone wanted to do something like this more mainstream, they could develop a third party bitcoin escrow service that offered an order history, rating or feedback system, and transaction comments from both parties. You could even develop a rating score formula similar to a credit score, where older accounts with more history, have higher scores, which make it much harder for scammers to use throw away accounts.

When I first bought the MBP 15" retina, my screen started ghosting. I got it replaced 3 times. Even though its an issue that was resolved with an update the staff at the Apple store told me they will not consider it to be a problem unless a certain amount of reports of it have been filed, so if you have the problem, report it, get your laptop sent in because they need laptops that produce this problem in order to fix it.
Well, I just tried to transfer one of my domains to Namecheap using Bitcoin, but their implementation leaves a lot to be desired.

I filled in my domain, got to the checkout page, and it gave me three options: Pay from 'Funds', 'Credit Card', or 'Paypal'. Turns out in order to pay with Bitcoin, you have to first add 'Funds' to your account. So I click the link to do that, it asks me how much I want to add (I don't know, aren't you supposed to tell me how much I owe?). Anyway, I follow a few pages and finally end up on BitPay's page where it asks me to send a specific number of Bitcoins to their address, so I do. The page recognizes immediately when I have sent the funds, and redirects me back to Namecheap.

Great, now I can find my way back to the checkout page and finally finish the transfer! Except I can't. Despite having sent the funds, they won't show up in my account for another hour (or possibly up to 24 hours). I understand they want to prevent double spend attacks, but this is absurd. We're talking about a $10 domain that they can just revoke if the payment doesn't clear. They have to wait 45+ days for paypal/credit cards to clear, but they give the product to me immediately, and I don't have to go through their ridiculous fund adding process to do so.

I applaud the effort Namecheap and I'm happy to see Bitcoin becoming more useful, but this needs work.

Seems like if a comet were headed to earth, the best bet would be to get as much mass into space, and shoot it as fast as you can in order to knock it off course.

Much less fun than a Bruce Willis shlock disaster movie, but seems pretty practical.

You can make an argument that Bitcoins is not a foreign currency as it can be mined domestically in your own country.
The trajectory of this comet makes things especially difficult. It is moving fast, travelling in the opposite direction of all the planets and is coming in at a large angle relative to the plane of the solar system. From Phil Plait's post it will be moving at over 55km/s relative to Mars during the flyby/impact. Simply intercepting this comet is basically impossible today.
This is beautiful to watch unfold: The universe is taking flight! Do help it, not for the sake of a cryptocurrency, but for the ethical implications. For you and for me.

It sounds like that was something with the API for BitPay, perhaps NameCheap will skip the wait in the future and revoke if necessary but the thing that worries me is that maybe the BitPay API doesn't support notifying on pending funds instead of secured funds.
This is crazy: MtGox is 37 USD/BTC today, up from 20 USD/BTC a month ago.
I have an Excel spreadsheet with rainfall records dating back to the 1860s. It turns out Excel does not accept dates before January 1, 1900 as valid, while dates far, far into the future (up to December 31, 9999) are perfectly ok. Nobody thought someone might want to enter a date before 1900? It's just bizarre.

It isn't just the everglades. Most of the area covered is rural, swampland, farmland, etc. and would not be under suspicion, ever. It is a ridiculous map. It would be one thing if waterways and major cities were highlighted, but it is just over the top, completely. Highlighting all of it makes people in those areas worry unnecessarily when they need not. Finally, Homeland Security does not have the resources to implement searches in all of these places, nor will they knock on the door of every random apartment in Washington, D.C.

This is a sideshow to real privacy problems and a waste of my time and yours. The ACLU should be focused on the fact that our communications are being monitored, because that is something that is much more worrisome.
Come to think of it, I think all of those guys get WAY too much individual credit for the success of their companies. Damn straight.
If it hits Mars, it could help to terraform the planet. The CO2 ice caps would melt and heat the atmosphere. It would melt a significant amount of frozen water in the soil and thicken the Martian air with water vapor too.

Wikipedia is predicting a 1 in 1250 chance of hitting Mars. Outgassing as the comet nears the sun could change its trajectory significantly also.

Many people (like myself) keep a fair sized balance on namecheap to make checkouts faster for credit cards in general, so this won't be a problem for everybody.

All of them? Maybe I misunderstand what you are saying, but if you mean that the random travel searches you scroll on the site are a feature, that is bordering on insane.

I don't need to go to some random place for some random duration at some random time.

So, since it would be insane to consider random trips to be a useful feature, I assumed that it was recommending certain trips because they were really good deals. Maybe your system figured out I live near San Jose, and recommended me a flight because it was just such a great deal it was worth my time to try that search and maybe go on a vacation on a whim. That would actually be an awesome feature, and I would probably use it a lot! So, benefit of the doubt.

So I tested that theory, and here is what I got:

http://adioso.com/us/san-jose-california-to-hawaii-hawaii-ne...

Best flight that Adioso found was $535 for that trip. BTW, Expedia never returns on your site.

Then I went to Kayak. It took me about 30 seconds to fill it out, and it took me here:
http://www.kayak.com/#/flights/SJC,nearby-HNL,OGG,LIH,KOA/20...

So, the best fare that Kayak found was a $277 hacker fare. That's almost exactly half as much as what Adioso found. Sure, that's a hacker fare, and for a 10 day trip not 7 days. Fine, the best fare that is exactly comparable is $350 for a 7 day trip leaving next week round-trip on Delta.

Using amphetamines to treat depression has a longer/safer history than using SSRIs for depression, too.
Any plans of releasing an affiliate API ?. I'am current creating a travel media site (think Tumblr + Tripadvisor mashed together) and i would love to integrate a intelligent, accurate & unobtrusive little flight search widget to the site.

For instance when a user visits a page under any destination (say Bangkok) I would like to present him with something like 'Flights from {Your Location} to Bangkok starting at {xyz}$" to get him to start his flight search.

Here the 'xyz$' pre-search number should be a real price that the user would see in the search results and not some unrealistic number that sites like Tripadvisor and Expedia use as link bait. The start location should be the user's current location and the destination should be from a list of options (e.g {dest: "Ko Phangan, Surat Thani, Thailand, Asia"}) specified while calling your API.

A few months back i explored various options available at that time and gave up on the idea as being impossible. But now, since you are making the impossible possible.. maybe you could do something about it? I'am sure that many other publishers would be interested as well.
It is such a beautifully built machine. I really think they should be making a cargo van. With that flat battery platform they can stretch the length, add an additional axle and power-train motor.

I think you're naïve.

Experienced amphetamine users are not able to distinguish the effects of amphetamine (Adderall) and methamphetamine (Desoxyn) in double-blind "taste tests". The main difference is that the effective dosage is different.

It's easy to abuse amphetamine in the catastrophic ways that methamphetamine is abused: you crunch it up and snort it instead of taking a slower-releasing pill, and you take higher dosages than you'd take to focus on your homework.

I would highly recommend people interested in learning more about ADHD itself to read Delivered from Distraction: http://www.amazon.com/Delivered-Distraction-Getting-Attentio...

It's a fantastic book that explains the condition extremely well and has tons of useful information on not only how to cope with the condition, but for how family members and relatives of somebody with ADHD to best support them.
I have been aware of the 100 mile zone for about a decade, ever since a friend of mine encountered a border patrol traffic stop on a freeway in Maine.

I looked at the BitPay API page (https://bitpay.com/bitcoin-payment-gateway-api) and couldn't tell for sure one way or the other. If it really doesn't, they may want to switch to Coinbase (a YC company that offers a similar service) which I know sends notifications immediately (and status updates as confirmations come in).

However, even with that fixed, it's still an issue that Bitcoin was not an option on the checkout page. I had to navigate somewhere else, then go through the checkout process again just to get back to where I was. I shouldn't have to stop what I'm doing and go through a completely different flow to pay for something.
If you are going to post online about a problem with an Apple product, I personally believe that it's a good idea to also file a bug (http://bugreporter.apple.com) and include a bug number in your post. Doubly so if you submit it to HN.

It is possible that there are people who work at Apple that read HN and if you post a bug number one of those people might then be able to open the bug.
Is that 10mg IR or 10mg ER?

10mg b.i.d. isn't a very high dose, which is probably why side effects are relatively low. It certainly sounds like it's helping you.

No, large doses of different drugs have very different effects. Massive doses of caffeine will make you anxious, shaky, and give you heart palpitations, but it won't make you have sex all night long or hyperfocus like amphetamine.

The reason large doses of methamphetamine have very similar effects to large doses of amphetamine is not that in large doses, all drugs are similar; it's that methamphetamine is very similar to amphetamine.
Relatively speaking, there is very little data to go off of as of now. The comet hasn't been tracked long enough for them to truly see if it will even be close to Mars.

I do think, however, that if it does look well on its way to hitting Mars, it'd be worth while to send a large chunk of mass and try to push it in another direction. It could prove to be a trial for a future, Earth-threatening instance. So far the ability to deflect a comet/asteroid is only a theory--putting it to practice is a great way to test it.
