I think the main barrier to having video lectures at the moment is cultural.
The current system involves in-class lectures, with homework done at home. If you switch that, have the students watch lectures as homework, and solve problems in class, the teacher (and other students) are actually available when the students need them most - while trying to solve the problems. It also allows greater flexibility for the students to "learn at their own pace" - students will have more options as to which lectures to watch rather than the whole class forced to watch the same lecture at the same time.
The article is talking about replacing traditional schooling methods (ie classrooms+lectures etc), not replacing tutors. The article is talking about MORE tutors - in short, you completely missed the point of the article.
Personally I believe lectures will soon be a thing of the past. Teachers should be spending their efforts actually interacting with students rather than a one-way recitation of material, which can be accomplished through video lectures (ie the guy from Khan Academy is a much better lecturer than 90% of teachers out there).
Why are so many bleeding-heart liberals exerting more energy defending dictators than working to remove them? Who do you think is helping Syria slaughter its people?
#1 Why do you suppose I am a "bleeding-heart liberal"? It seems that just because I disagree with you, you need to find some label to place on me.
#2 I have no problem with removing dictators. I do have problems with the American establishment doing it under the pretext of "they have weapons of mass-destruction!!!", when they decidedly do not.
Your first two citations re:Russia selling Iran nukes have nothing in them saying that they do. In fact, your second citation explicitly says that Russia is NOT selling Iran nukes.
Your third citation is a claim that has been proven to be completely bases several times.
You are twisting the facts to support you own perverted world-view.
Saudi, Isreal, Pakistan, India, North Korea. All allowed to have nukes, but with 0 evidence the world puts huge propaganda and sanctions against Iran, and the U.S. starts a habit of routinely invading their airspace.
To all the people warmongering against Iran:
If anyone can show conclusive proof that Iran is working on a nuke, I will buy into the war machine.
Otherwise, please tell these other countries to disarm or you idiots can STFU about Iran.
Every single intelligence service in the world is in agreement that Iran is developing nuclear weapons.
No, they are not. Not even all the U.S. intelligence services are in agreement about this. The"official" stance is that they are working on them, but there have been several public dissenting views come out from your CIA and FBI.
Of course Russia is selling billions of dollar's worth of weapons to Iran (and Iraq before that)
[citation needed]
#1 Iraq did not have weapons, ergo Russia did not sell weapons to them
#2 If Russia already sold weapons to Iran, they already have them, therefore their "proliferation" is a done deal.
Please stop making shit up.
The real issue is that there is significant international pressure for Iran to stop its nuclear program for civilian (power) purposes. First off, Iran is quite correct in that this is unfair as they are have signed the NPT, and have cooperated with the IAEA. Secondly, now that such crippling sanctions are in place against them, why should they stop? They are rightly convinced that the world will view them as a nuclear threat whether or not they stop their civilian program, and they now need that civilian program more than ever due to the sanctions.
Economic sanctions are a precursor to war. The American propaganda machine wants war with Iran. When have you ever known the American's to let the truth stand between them and one of their holy wars.
Reminds me of the Duck/Battle Chess story. I'm not sure where I first read this, but it goes a little something like this;
This started as a piece of Interplay corporate lore. It was well known that producers (a game industry position, roughly equivalent to PMs) had to make a change to everything that was done. The assumption was that subconsciously they felt that if they didn’t, they weren’t adding value.
The artist working on the queen animations for Battle Chess was aware of this tendency, and came up with an innovative solution. He did the animations for the queen the way that he felt would be best, with one addition: he gave the queen a pet duck. He animated this duck through all of the queen’s animations, had it flapping around the corners. He also took great care to make sure that it never overlapped the "actual" animation.
Eventually, it came time for the producer to review the animation set for the queen. The producer sat down and watched all of the animations. When they were done, he turned to the artist and said, "That looks great. Just one thing – get rid of the duck."
and little in the way of substantial drawbacks (besides being politically incorrect, of course)
Please see my post earlier:
Also there are other problems with GMO's other than the human health concerns. Which again you might know if you had any idea what you were talking about.
Granted, I was not being specific, but there are substantial drawbacks.
The most immediate being that, due to the increased use of chemicals on chemically resistant strains, you get the development of killer weeds, increased ground water pollution, and the destruction of the local ecosystem. There are also IP rights issues (for the GMO companies), and property rights issues (for the non-GMO companies) concerning cross-pollination of GMO crops onto non-GMO crops.

All merchandisers know that iUsers have more money than sense and price accordingly.
Note: this is not to say that they have a lot of money, but rather that they don't have much sense.
There is a myth that goes something like "Macs are expensive, therefore only the wealthy can afford them.". Not the case - in fact it is the opposite - these people simply do not know how to manage their money.
2) Pay with game cards. If you can pick them up at Walmart even better. But, you can buy codes online.
I generally pay with Paypal (commence Paypal is evil etc etc) to avoid having my cc# floating around the interwebs. With Paypal they are not authorized to re-bill (unless you tell Paypal to setup a subscription), and if the servers are compromised, identity thefts can't do all that much with just your email address (assuming you keep your email account secure).
Granted, not as secure as game cards, but just as convenient as entering your cc#, and 100x as secure as THAT.
Ya I don't know where you're getting your information, but this one study is not "overwhelming scientific evidence". There are multiple other studies showing the opposite. In fact, if you'd read the summary you'd notice the several sentences regarding "impossible to prove a negative etc need more tests etc" - ie this study says nothing conclusive in any way.
I suppose you also believed the tobacco companies when they told you there were no negative health risks.
Also there are other problems with GMO's other than the human health concerns. Which again you might know if you had any idea what you were talking about.
(Oh, and for the record I do not reject vaccines or evolution)
Just FYI: I don't personally have their data plan so I can't comment on speeds/service, but AFAIK they use Rogers' towers. I also do not leave the GTA very often so can't comment on roaming rates/service. Their call rates are 25 cents per minute.
If Skype ever becomes fully integrated into Android (unless it is and I am not aware of it) I might consider signing up for speakout's $10 data plan and solely using Skype for calling. As it stands I am not a fan of the usability, features, and integration (or lack their of) of the Skype app.

It's also pretty easy to "translate" something incorrectly and then yell bloody murder, like what the US government and mainstream media has done.
Not only do governments have it (which they require if it is to be used for anything classified) but universities do too.
Would some kind soul at a university in possession of said source code please put it in a torrent. kthnxbai.
