> Children with ADHD have a significantly higher rate of missing or duplicated DNA segments compared to other children

The problem with this study is they looked at kids who had been diagnosed and were on long term drug therapy. This is similar to studies that show that ADHD diagnosees on long term drug therapy have "brain damage", which matches the brain damage of long term stimulant users. The findings are not an indicator of ADHD, they are indicators of brain and genetic damage from long term drug use.

Much more effective than Ritalin, and safer, for treating ADHD is the prescription drug Desoxyn. It's not used as much because of the stigma of taking methamphetamine hydrochloride. I mention this because everyone agrees that methamphetamine is not an innocuous drug to take long term, the same goes for Ritalin, they both have very similar effects on brain chemistry.

I read the first edition when I was in high school eleven years ago. Even back then it was considered the standard go-to book for learning the basics of algorithms and data structures. If your bookstores weren't carrying it, they must have not have been well stocked.

My opinion of the book nowadays is actually somewhat low. The content and style is competent but generic and uninspiring. It does a poor job of teaching algorithm design, but admittedly that is a flaw with most of these books. Udi Manber's lesser-known textbook is just a lot better in that regard. It does mean sacrificing some breadth of coverage compared to CLR. For me it's the right trade-off because so much of CLR's coverage comes across as perfunctory, as if they're just checking boxes off an endless curriculum list that's intended to please everyone, much like the big calculus books. The grab bag of advanced chapters in the book's last half are the exception to that rule. They're usually in the authors' own research areas, and it shows.
Hasn't the market fluctuated fairly rapidly in the past few months? I'd hate to accept $10,000 worth of conference fees in bitcoins, only to find out that I can only get $5,000 out of them. At a rate of $1,000 a day - or whatever the exchanges are limiting the daily trades to these days.

That is scary.

My experience,when I was addicted, was that I couldn't find a doc to prescribe them for me. Was it the dead-faced junkie staring back that prevented it? Probably.

It's sad they are so heavily prescribed again, because I know how it feels to rely on a pill to stop the pain and get out of my own head/anxiety. I'm lucky to have found another way.
I think I've changed my mind about the project, reading everyone's opinions here. At least sort of.

An analogy: You have some clothes, and you build a little covered rack outside your house on the street and put a sign up that says "clothing swap, takes some for yourself or leave some for someone else." Some people take some clothes and drop some off. THEN some guy comes along and says "this is BS, it's just a bunch of yuppies trading clothes" and proceeds to take all the clothes and bring them to the goodwill, where he believes they'll be put to better use. He does this a few times.

Now, if I were the project founder or a clothing donor (or taker), I would be pretty pissed if someone decided to take all the clothes and give them to Goodwill because s/he thinks "they'll be put to better use" there.

1. There's an ulterior goal here (community building) that is scuttled by you taking all the clothes
2. How do you know I don't give to poverty related charities already
3. I have my reasons for not giving to Goodwill
4. Even if you think it's stupid it's not your decision.

On the other hand, if I leave a pile of dollar bills in a bowl on the street with a sign that says "please take only one," would it be reasonable of me to get upset when someone takes more than one? In my opinion it would not be reasonable. Someone abusing the system was the inevitable conclusion of this experiment. That doesn't make what he's doing "right," per se, but it seems silly to rage about something that was predictable with 100% certainty.

EDIT: downvoter: which part didn't you like? I put a couple of different points in one post (I know, my fault) so I can't tell what you're objecting to. :P Just curious.
I can see how a data lockdown would be offputting, but I read this as a story about how some algo at Apple stopped a thief from stealing as much as he could have otherwise.

One of the main gripes seems to be that Apple "let this happen" -- but enabling app commerce is what they do. Someone gets ahold of your credit line, they go buy stuff. Best Buy doesn't "let it happen", neither does Visa. After the fact they are just mandated to limit the damage to which you're responsible.

I'm not sure I could tolerate it any other way. Personally, I would not enjoy a system where some human calls me up every time I make an app purchase. I feel Apple's sin of omission is forgivable here and see it as laudable that some software algo that stopped it after $40 bucks or so. I'll be interested to read, however, whether or not Apple holds this gentleman accountable for those purchases and whether or not they fallback onto the credit card provider for damage limits.
When my house was burgled, the cops sent out 3 cars, did a thorough inspection, took inventory of what had been stolen, and dusted for prints in places we indicated were likely to have been touched (the windowframe where they came in, some doorknobs, and the box fan they had moved). This was in Rochester's 19th Ward (New York), possibly the most dangerous and high-crime part of town.

As far as I know, they never caught anybody, but at least they tried. I'm pretty sure it was my drug-dealing neighbors two houses down... especially since the guy three houses down claims the security cameras on his porch showed them taking stuff from our house to theirs. Oh well.

He's free to criticize the initial experiment all he wants, but to hijack it and abuse it as he sees fit can't be objectively interpreted as anything but pure douchebaggery.
Are there examples of things that were fixed by Apple specifically because Gruber blogged about it?
I just bought a Synology DS411j yesterday and I intended to run AeroFS on there. Unfortunately, AeroFS requires the JVM which I believe won't run on my NAS. (JamVM might with some hacking). Hopefully there'll be a solution soon because I really hoped I could setup my own Dropbox at home on my NAS.
What about "Hacker News"?, some of the news here are not Hacker specific. In the guidelines of this site, it says, that here can be posted articles that comply with this: "anything that gratifies one's intellectual curiosity" So, this site could have be named "Intellectual's News", and not Hacker News?

I'm not a hacker, and love to read the stories here, this is my favorite site to read news every morning.

Yes, you are all right, the term Hacker is misused everyday, and the tendency is growing.

I occasionally "hide" bills in selected sections of textbooks I've been meaning to read. It serves as a perk or secondary means of positive reinforcement (the primary being learning interesting/useful stuff). It also indirectly brings the material near where I've stuffed the bill to the forefront of my mind, even if I'm not incentivizing myself with cash. "Where was that $20? Oh, near Djikstra's algorithm. I'd been meaning to look that over."

I don't know why he is blaming apple for the security measure. It could be apple's fault that he was hacked, it could be otherwise. Still apple only knew there was a new device using his account, legit or not it didn't know for sure. I have at least 9 iDevices hooked up to my account as of late, on average 3 more each year. And I don't think apple can do much more to validate each and every one of them without being intrusive and annoying.

Dude, the word "Gruber" is a hyperlink in the article. Just click on it.
This was pretty early on... 2008 I think.
That is one way to do it, but it is also a way for conversation to devolve (youtube comment threads?). So it is a balance. While anonymity may allow some people more freedom to express themselves in a positive way, it also makes it easier for people to express themselves in a negative way that may be considered harmful as well.
I've been running an event in the UK for around 4 years now. We have around 1200 attendees and push around £55,000 (around $90,000) through each year.

We had a few small issues the first year where paypal froze our account until additional verification had taken place but since then and three years of continuous use we haven't had a single problem. However we've also never had a chargeback so I would imagine that's heavily worked into their risk calculations.
Dextroamphetamine is a psychostimulant drug which is known to produce increased wakefulness and focus in association with decreased fatigue and decreased appetite. Drugs with similar psychoactive properties can be referred to or described as "amphetamine analogues", "amphetamine-like", or having "amphetaminergic" effects. Enantiomerically pure dextroamphetamine is more potent than racemic amphetamine and has stimulant properties similar to racemic methamphetamine, though it is less potent and has not been shown to cause neurotoxicity, which is associated with methamphetamine use.

What happened to it was that credit card companies discovered that they could gain additional customers by removing that risk. The end result is now that most or all credit cards cover the cardholder in the event of a fraudulent purchase.

Feel free to run your own conference where "caveat emptor" is the rule for buying tickets, but you won't be able to take credit cards or various other forms of payment for it.
If you're using Flickr as a carefully curated art portfolio, I agree, it's unusual and easy to sort.

If you're using Flickr as an event display solution, it's quite easily done.

I have two pro accounts with Flickr, specifically so I can shoot and present events while still leaving breathing space for my general work. By and large I like it, but there are definite issues with bulk tools and this is one of them.
Since there's no credit card associated, it couldn't have asked you to verify you via the CVV in an automated way, so perhaps it skipped this extra security step that other account holders have.

The real question is whether you a) can or want to afford a laptop, which still tend to be relatively more expensive than desktops

As far as I'm concerned, this is what it really comes down to. At least for now, while you can in general find a laptop to meet just about any desktop as far as features or performance, there is always a non-trivial price premium.

Once there is not, desktops will vanish overnight (except for the diehards or those with special computing needs) because you can just plug a laptop in to the peripherals belonging to your old workstation.
Oh, I see. You're saying each instant query would count as a query, rather than the instant query "session". That makes sense.
I think this issue is orthogonal from the one mentioned on the discussion board. My understanding is that the user on the board is complaining about someone stealing his card number and using it to buy stuff on iTunes via the hacker's own account; the OP is complaining about somebody using the OP's iTunes account (and possibly his PayPal account?) to buy things on iTunes.

It sounds to me like the developer of the app purchased might be in on this - there are apparently multiple reviews saying that the same thing happened to other people. Or maybe said hacker(s) just like playing that particular game?

Edit: I completely agree that do_not_reply is the wrong address from which an email like this should be coming.
I launched a small site using D3 (windhistory.com). It's great. SVG is now supported in Firefox, Chrome, IE, and Mobile Safari. The big limitation is IE7 and IE8, but if you can blow those users off SVG is fantastic.
I used to use Fastspring but your prices are simply too high. With Stripe I save more that half in fees.

Really??? The author of this post is comparing the number of Facebook likes (750 million active users) to the number of Google +1s (some 25 million users) from a small sample of Internet articles...

People really need to stop mentioning how Google+ does not have this or that feature. It's not open to the public at large because it's not a finished product yet!
I used to use FS but now I use Stripe and I save 50% or more in fees. Your fees are very high.
Hw the f am i supposed to know that John Gruber is an apple fan boy by reading his About page.. it
Id do one thing slightly different.

I would set up an icmp proxy with ssh on top of that. And there would be a few good reasons for that. 1: it bypasses a whole lot of firewalls and captive gateways. 2: few hackers would expect such a communication mechanism like that.

Of course, this solution works only if the computer isnt reformatted, as i would do if i ever got into petty theft. So one would need the computer to have an open and easy to get into account. If you use linux, have home directory encryption on and the account called "Administrator".

Yes, it's part of the social experiment and it was a pretty cool hack.

I think a more accurate scenario is:
Q: What happens if you let everyone contribute to and buy coffees from a Starbucks card? A: We are in the process of finding out but some very smart but unethical folks are pulling funds outside of coffee purchases and ruining the pot for everyone else.

I've worked with SmugMug on some projects and I'd say they actually have fairly robust social/sharing features–they just may not be marketed well.

They have tons of social network sharing & embed features. Plus a great API. Their categories and subcategories can act much like Flickr's groups but I simply think people don't use/browse them much.
The most frustrating thing about Python is its community's complete denial about what a joke their concurrency situation is. Truth is python is not truly multi-threaded, and no, claiming that multi-process is the way to do parallel computation across the board is not a sane argument at all. It's religious zeal. My company is currently using it for web apps, and that's proving a pain (i.e. having to use proxy servers for database access to minimize connections across all the python process instances). Using python for anything more serious, like a message queuing system for example is even more prohibitive. People in charge should wake up and start taking serious steps about it. I guess PyPy is the biggest hope. Meanwhile in the JVM world..

> I dont' understand. Isn't this going to happen if you have multiple threads running even if the GIL is blocking them from running?

I don't think it would. If there is a GIL (Global Interpreter Lock) only one thread of the process can be scheduled to run at any time. As the poster (Sturla) says, Python threads are native OS threads so they should be scheduled by the OS kernel (right?). A good scheduler would use affinity scheduling and schedule all threads of the Python program on the same processor/core every time to get benefits from cached data and code. I believe modern kernels (Linux, MacOS, Solaris, probably Windows as well) use this kind of affinity scheduling, so if we're lucky the Python process gets scheduled on the same processor every time and there will be no need any cache synchronization.

> I'm not a hardware expert, but I'm not sure how constant locking would prevent cache synchronization just because they weren't truly running in parallel.

I'm not sure if you misunderstood the mail. The constant locking would only be used if they were running in parallel.

Anyway, if you have a GIL you don't need that kind of locking described in the mail. You only need to do explicit locking on shared data structures when you read or update the contents of those data structures. If you have reference counting, threads that run in parallel and no GIL you would have to lock even if you are just assigning a reference to such a data structure to a new variable. If you have a GIL you are certain that only one thread at a time are updating the reference count. That is indeed what the GIL is, one coarse lock for all data (and the interpreter) instead of fine grained locks for every data structure.

(I don't know Python very well, I just answer from general knowledge of computer architecture and language implementation. But I've read about the Python GIL several times, since it's the most discussed GIL of any language.)
"I think there's a huge opportunity for a startup that operates a social network that actually caters to people's desire for anonymity and privacy."

The problem here is that any successful endeavor will inevitably turn evil in some way. Once millions and billions are on the table, investors and shareholders will force the proprietors to scrape every bit of money possible off the table. That will usually involve some user-unfriendly behavior, like Google's real name, Facebook's ever changing privacy policy, and LinkedIn's recent emulation of FB.

The only way that social networks can be pro-user is if they are a standards-based commodity like email, where anyone is free to implement the standard and offer the service. You can get the same email service anywhere you want, interoperable with every standards based server on the planet. It should be the same with twitter-like message bursts, and social networks.

As it is now, bursting and socializing is built similar to early telephone networks, where many companies offered networks, they didn't connect to each other, and businesses had to have multiple network accounts to be able to interact with all their customers. That's just wrong.

fastmail.fm offers excellent email service. They should also (be able to) offer standards based bursting and socializing; so should anyone else who wants to.
It's clear that their stated policy is not the same as their actual internal policy. If it were, the outcry would be half the size it is.

Google is lying about what their policy actually is, plain and simple. Questions of anonymity aside, the much of the outcry is because of the severe dishonesty being displayed by Google.
He's not feeding the poor, he's feeding his ego and acting holier than thou. If he wanted to make a donation to charity, he could do that without subverting an experiment under the guise of "helping people who really matter."

I find this entire episode disgusting and if being a "successful entrepreneur" means acting like a douchebag like Sam, may I never be successful. Incidentally, MOST successful entreprenurs I know (and many are far more successful than Sam could ever hope to be) don't act like this. They have better things to do than jack money off a community Starbucks card so that they can create Internet drama.
