This is really just an illustration of quantum cryptography, rather than quantum teleportation. Quantum cryptography is a method of exploiting quantum effects to create a channel that can be used to transmit classical information in a manner that cannot be eavesdropped.

Quantum teleportation is kind of the opposite. It uses a classical information channel in order to transmit -quantum information-, which can't actually be represented clasically. It is actually moving the superposition itself from one place to another. The term "teleportation" is used because the "no cloning" rule (quantum information cannot be "copied") means that the information is no longer in the original location.

This is mostly useful in quantum computers, because in order to actually process information it's pretty important to be able to get it from one piece of the machine to another, and until the recent teleportation breakthroughs building quantum computers that could handle more than a couple "qubits" was pretty much not doable.
No, it does not. You have to intend to film child pornography to satisfy the mens rea element. Filming something accidentally, by definition, will not satisfy mens rea.

Well, there's your problem. I didn't prescribe them to you or your friends. In fact, you seem to be confused as to what it means to be anorexic. Anorexia is not a state of low body fat; it is "an eating disorder characterized by immoderate food restriction and irrational fear of gaining weight, as well as a distorted body self-perception" [1] and a serious mental health issue.

Most of Traci Lords' pornographic videos were produced when she was under the age of 18. It is unclear exactly how many people knew this or facilitated it. The company that produced her videos was prosecuted and practically all of her films have been banned in the US.

I recently got a copyright takedown request for a site of mine from a competitor. Of course the request was bogus, but the availability of template copyright takedown emails online makes it very easy for any Joe to request a takedown. Maybe requiring more effort for people to submit takedown requests could help minimize bogus senders.

On the client you have callbacks every time an object has an event handler. It's not just AJAX. And yes, anyone familiar with client side JS should understand and be using callbacks everywhere.

It's not theft, though. Copyright infringement is civil, not criminal (correct me if I'm wrong). Filing a suit against someone is a more apt analogy, and nobody gets to file for free unless the lawyer thinks there's a good enough chance at a monetary award.
You know, in a lot of sci-fis its not implied that teleportation is faster-than-light. Quantum teleportation does meet what does seem to be universal about "teleportation" though, which is that the "original" is necessarily destroyed. That is, it takes a thing, and moves it to another location, rather than copying it.
I assume they mean memory will be integrated into the CPU package itself? If that provides for faster RAM, smaller computers, and greater power efficiency I would find it to be an acceptable trade-off. I've found over the years my RAM needs are tied pretty closely to my CPU needs. Today I can get by fine with 8GB but by the time I need 16 or 32GB I will probably want a newer CPU as well. So doing this all in one package wouldn't bother me. I'm guessing on desktops/servers there would be some ability to add slower modular RAM to compliment the faster RAM integrated into the CPU?
Understand that I did not post that question for reasons of vanity. I really wanted to know what led you to that belief (I have not found much evidence supporting it) and am still interested in knowing, in order that I might update my beliefs if necessary.

I at least cited something. I picked up the article I had read most recently. Speculative or not, it was published in a peer reviewed journal by those active in the area. I urge you to do your own research and come to your own conclusion. As these things are not known one can only give hypotheses on their causes. Statistics which are often not done well in the medical field are not necessarily stronger than reasoning from first principles.

If you have access to any geneticist, autism researchers or biologist do ask them. And consider. De novo mutations are culprit for many rare diseases including those like autism (each particular case often to rare causes) with non-specific causes. In terms of the gametes which both parents provide, sperm cells unlike ova, have a vastly larger number of these errors with probability increasing with time. This is a stronger argument than something is hard to observe and does not assume that the researchers did not think of something fairly quite obvious. The reason for Down Syndrome and maternal age also has a solid biological hypothesis that is almost inverse (not new mutations but chromosomal damage, usually catastrophic -> miscarrying).

I was actually interested in what made you come to hold this belief because it is not in line with much of what I have picked up in the literature. If you can give a solid counter reference, speculative or not I would be interested. A cursory search on my part did not find anything supporting your claim.
Very handy. What I really want to see next is a side-by-side comparison of how much Glacier and S3 Classic cost for given usage pattern(s). It's deceptively simple how Glacier is hands-down cheaper than S3 if you write only for backup, but could be more expensive depending on when you need to access that backup. :/

possessing the evidence is a crime, unless you can make an "affirmative defense" (I've commented about it elsewhere on this page.)

There is a difference between an actual murder and a depiction of a murder. In the former, someone actually dies. In the latter, an actor falls over.

The actual crime is very much an element to the illegality of a snuff film. Snuff films are illegal precisely because someone actually dies. Child porn is illegal because a kid actually gets raped.

There are a few rare situations involving "fake" child porn. Should these be illegal? The Supreme Court has said that virtual child pornography might not be illegal but that either way such content was justification for holding a person in a mental institution as a danger to others. There is an extremely high (as in, greater than 80%) correlation between willing viewership of child pornography and attempts to abuse/molest/rape a child or acquire actual chil porn. With pedophiles, child porn isn't just an abstract media form like a TV show; it's like going to a Ku Klux Klan rally with a snuff film showing a black man get lynched and exhorting the crowd to do the same.
Okay, but if you, specifically outlaw murdering me, this will surely draw attention at my person and might harm me.

You might be outraged, but you should only be confined to measures that 1) are proven to work, and 2) can be enforced consistently.

It looks like a law against abortion does not usually work: abortion is illegal in africa but they do much more abortions per one person than in europe where it is generally okay.
So if you really care you should take good parts from what europe is doing and work on that. But if you are religious, you take pride in acting irrationally but faithfully, and you will jail people up, spread unsafe illegal abortions and hurt the bottom line (no of abortions per person in your country).
You know, Jesus died so you can do all of that and still feel saved.
It's socially somewhat acceptable to fantasize aloud about torturing child abusers, even for members of religions that have disavowed torture for several generations. I think this is driven by an instinctive rage rather than a cynical strategy by leaders of religions. Making child porn more inaccessible than abusable children has obvious drawbacks besides starting down the path to crimethink, though.
I've had a few of these created by OSX for me when I disconnect/reconnect to an external monitor.

I find it weird that people use Stackoverflow as a community where they hang out and spend time. The obvious way to use Stackoverflow is when you're having trouble figuring something out you get there via google. While doing your research you might come accross an unanswered question that you know the answer to so you write it up. That's it. It's a very useful site but there's no need to get emotionally involved with the reputation score.

As far as using the score to get a job, I don't buy it. If you're actually good at some topic you will be able to get a job regardless. If I was hiring someone who was pushing their super-high Stackoverflow score I would be suspicious why they spent so much time gaming a dumb score on a website instead of building cool stuff.
Oh, sorry. I misread "In any case, I'm actually really interested in the comment about spite Gruber makes at the end." as "In any case, I'm actually really interested in the comment Gruber makes at the end. Can anyone answer that?"

I've been developing web applications for about 17 1/2 years. I've worked on a huge range of what would now be called "stacks"; everything from ASP/SqlServer to Java/Oracle to Perl/MySQL and a whole bunch in between. I even worked on "web services" in 1999 using Oracle/Corba/C++ and CSV-over-HTTP.

The main thing I've learnt is that these choices made almost no difference to the success of the project. Skilled engineers using whatever tools they are experienced with make successful products.

I made a satirical hot or not type site called hipster or homeless. Perez Hilton retweeted it and I ended up using that to as a segue to contact different news organizations. Being in the SF Bay area, there is an omnipresent homelessness problem here, so NBC bay area decided to relate the website to raising awareness of the homelessness problem. They did a news segment on it and interviewed actual homeless people. http://www.nbcbayarea.com/news/local/Hipster-or-Homeless-124... is the segment.

The author's point is true of all surveys and has nothing to do with Google Consumer Surveys in particular.
Interesting! If you don't mind me asking, what kind of paths are they pursuing (ie lib arts v. pre-law/pre-med v. engineering)?

As for me:

I'm attending the College of William and Mary in Virginia (small public school, primarily liberal arts) and double majoring in CS and Business (ironically, I came to the College as a prospective English major -- I only switched less than two years ago, and haven't looked back.)

I had the opportunity this summer to intern for Big Tech and it was literally the best three months of my life, so I'm confident that programming is the way to go for me. At the same time, I feel as though I've had a tremendous advantage by being 'the computer guy' in most of my b-school classes, and I definitely don't share the stereotypical disdain of managers/business folk.

In terms of debt, I'm going to be graduating with only barely four-figures, thankfully in part to a) Pell Grants (state-granted need scholarships), b) merit scholarships, and c) working 20 hrs/week since freshman year. Another commenter mentioned that it's pointless to work during college because it barely puts a dent in tuition, but I've found:

- Working minimum wage at the rec center might not give you that much money, but I was able -- as a 16-year-old college freshman -- to make at least $20/hr (much more at this point) through tutoring and basic (talking Wordpress and CSS here) web design. $20/hr * 20 hrs/wk * ~15 weeks/semester = $6000/semester.
- Despite the amount of 'get an internship! get a nice resume!' advice thrown at college kids, very few of them actually follow through. I've interviewed with more industries than most other undergrads, and found that universally having two-three solid experiences (ie. not lifeguarding) is a huge differentiator.
The "ask for forgiveness rather than permission" is what is needed in all aspects of life as far as I'm concerned. It's generally what I live by.

It looks like the RealBASIC version was written first and then translated straight into C#.

In reality, you'd not create the encoding each time, and either use a StringBuilder to build up the string, or just use Encoding.GetString.

C# on my machine:

As per blog: 50s

Creating Encoding once: 24s

Using StringBuilder: 11s

Using Encoding.GetString: 2.5s

Use Random.NextBytes: 2s

RealBASIC on my machine:

As per blog: 27s

Interestingly despite advice I'd found on the internet[1] using array joining didn't really make the RealBASIC version any faster, so from what I can tell it's generally as fast as it could be using the out of the box libraries.

(My machine isn't exactly idle and ideal for microbenchmarking atm, but the differences are large enough for that not to matter)

This doesn't really provide a good evaluation on the state of JITs.

Yeah it's a tricky balance - it's 3 notifications per item you "stash," so it isn't too bad. But our plan is to make a mobile app with push notifications so we can control the notifications and make them intelligently timed.
So, is this based around a Spaced Repetition system, or just some standardly spaced reminders? Would this be an alternative to Anki? Or is it just meant to solidify some small set of facts using reminders?
