L.A. Science Teacher Suspended Over Student Science Fair Projects

clovis It's a good start. (247 comments)

After shutting down all science projects that involve projectiles, we need to move against other deadly militaristic skills.

1) stop all activities that train for grenade throwing.
For example, one so-called sport has a group of five taking turns attempting to throw a projectile through a 'hoop', where it should be obvious to anyone that this is training terrorists to hurl molotov cocktails through the windows of our leaders homes as well as elementary schools.

2) stop all activities that train for Hoplite style of battles.
For example, one so-called sport has a groups of eleven engaging in pushing and shoving to get a ball to a goal behind the group.
This is clearly military practice to train for close quarters combat without firearms. No doubt their plan is to disrupt the police who may be engaged in clearing streets from deranged people such as the occupy Wall Street protestors.

3) debate clubs. Why do we need debate clubs except to train people to delude and confuse the populace? The government licensed media should provide all the news and opinions we need.

Study: Video Gamer Aggression Result of Game Experience, Not Violent Content

clovis Re:Yeah...but no. (180 comments)

I have to disagree with that. I strongly doubt poorly designed gameplay/games will make you turn violent.

As for hard games? Games were much "harder"/tougher to complete (overall) 20 years ago than they are now and we're seeing a much higher level of violence in today's youth.

Umm, no we are not seeing a much higher level of violence in today's youth. Violent crimes peaked in the 1970's and has dropped ever since then.

I know of a mechanism that exaggerates small variations into having the appearance of large ones. It consists of truncating a graph by cutting off the bottom of the scale.

Study: Exposure To Morning Sunlight Helps Managing Weight

clovis Re:correlation does not prove causation (137 comments)

If they really wanted to find out whether sunlight affected weight, they would have done a randomized, controlled trial.

They would have randomly assigned half the people to getting exposed to sunlight early, and the other half to getting exposed to sunlight late.

Instead, they let the subjects go their merry way and simply measured their exposure to sunlight during the day.

These kind of studies give spurious results. For example, suppose the ones who are exposed to sunlight in the morning are getting up early to start their day jogging.

Well, no.
You don't begin a line of inquiry with a randomized, controlled trial. You begin with a study to see if there may be a correlation.
Why? If there's no correlation in a study, then there's no reason to spend the (much greater) money on a randomized trial.
If there does appear to be a correlation, you report it so that you (and others) may pursue the inquiry further.

Are DVDs Inconvenient On Purpose?

clovis Netflix already explained this. (490 comments)

At the beginning of the article, you ask:

"Why do Netflix and a few other companies keep the DVD format alive, when streaming is more convenient for almost all users?

At the End of the article you then say:

I'd be interested in hearing other theories, as long as people understand the question: Why movie studios don't allow movies to be streamed in a manner that mimics, as closely as possible, the experience of checking out DVDs by mail from Netflix (including, say, a mandatory delay between the time you select the movie and the time that you can watch it).

"as long as people understand the question:"?
Which question? The second question clearly answers the first question by asking "Why movie studios don't allow movies to be streamed...". The question itself is saying that movie studios don't allow streaming in a manner to match DVD by mail, so that's why Netflix doesn't do it.

Netflix already explained why they don't license everything for streaming.

I used a almost secret hacker tool (used by the CIA, FBI, and NSA!) to get this information.

Remote ATM Attack Uses SMS To Dispense Cash

clovis Physical Access = owned (150 comments)

This is a physical access attack and therefore not very interesting.
To do this you have to cut the ATM open at the point where the computer is installed and attach a smartphone to the USB port (or in older versions, a USB stick, or keyboard). They recommend upgrading the OS and securing the hard drive. How about putting epoxy in the computer's device ports?

Google Chairman on WhatsApp: $19 Bn For 50 People? Good For Them!

clovis Re:Read between the lines (303 comments)

That chart does no such thing. According to that chart Greece, Ireland, and Latvia have over double the productivity of France and nearly triple that of the US. You cite that, did not read it, and then go on to say the figures are worthless. Then modded up to +4 insightful. It is as if no one bothers to think or even try to learn something about the world.


That chart does no such thing

That chart does no what such thing?
I say the two charts conflict and that furthermore both charts are not useful for the comparison the OP we're responding to who said "France has higher hourly per capita productivity" and the person who essentially said "it's the opposite"

I think that you fail at reading comprehension in regards to my post.
I did read both charts and the original web sites (The Conference Board and stat.ee) that they are referenced from.
I cite the second chart only to show how the two charts conflict. I said it agrees with ebbo-10db. AT NO PLACE DID I SAY THAT I AGREE WITH EITHER CHART NOR DID I AGREE WITH ebbo-10db.
I am not ebbo-10db. That is a different person.


According to that chart Greece, Ireland, and Latvia have over double the productivity of France and nearly triple that of the US.

Which is, of course, ridiculous and would be exactly my point if it were correct. I quote myself: "I say neither chart is useful."
BTW, neither chart shows Greece, Ireland, Latvia having double/triple productivity over France/US. I can't see how you concluded that unless you had confused the chart that shows "change over previous year" with the productivity/hour charts. Your point is supported by Lativia's having 122 vs US 104.8 in 2009 in the 2005=100 relative chart (or similar years), but that's about 20%, not nearly 300%.

FWIW, I thought for sure that someone would call me out for using Estonia's economic reports.
For that reason, I suspect that you, AC, did not actually look at what I offered.

BTW, The EU has their own web site http://epp.eurostat.ec.europa.... for the same kind of tables with different numbers.

Google Chairman on WhatsApp: $19 Bn For 50 People? Good For Them!

clovis Re:Read between the lines (303 comments)

Or this, which agrees with ebbo-10db: http://www.stat.ee/64454

I say neither chart is useful. It's just dividing the GDP by guesses at how many hours are worked by the people in each country. It really just tells us that some countries get their money in different ways than others.
What we would want to know is how productive a worker is in comparable industries.
Consider that Norway's economy has a huge component of production and export of natural resources (oil etc) while Luxembourg is almost all financial services and perhaps banking secrecy.
There is no meaning in comparing the dollars produced by an Norway oil platform worker to that of a Luxembourg bank's US Treasury bond manager.
I'm surprised France is as high as it is considering how much of its economy is based on agriculture. That is to say a high labor-low pay industry, and similarly for tourism.

Can Science Ever Be "Settled?"

clovis Re:i interpret it to mean (497 comments)

My observations over the decades showed that the rule is this:

It's called a "law" if the person who thought it up called it a "law"
It's called a "theory" if the person who thought it up called it a "theory"

E.g., the approximations known as "Newton's Laws of Motion" compared to Einstein's "Theory of Relativity"
Consider also:
Moore's Law of processor performance.
Anything called a Law in Economics
Once so named, it stays with that name with little relation to the validity of the thought.

Australian Company Claims Laser-Based Quantum Crypto is "Unbreakable" (Video)

clovis for tl:dr (84 comments)

It's a one-time pad system. OTP systems are theoretically unbreakable. The weakness of OTP systems occurs during the exchange or transmission of the OTP to the recipient.
They claim that "Any attempt to intercept the exchange of the key causes detectable variations in the quantum states carrying the cryptographic key, alerting both sender and receiver to the attack and allowing them to take mitigating action."

It appears to me that the catch is that transmissions must remain on the fiber link of their equipment, I.E., in-house.
Did I understand that correctly?

Is Google Making the Digital Divide Worse?

clovis envy (259 comments)

An old joke about neighbor envy ...
An angel in disguise visit a peasant's hut and is brought inside. The peasant shares what little food he has, and lets him sleep under his only blanket.
The next morning the angel reveals himself and tells the peasant he will be rewarded, but the catch is, whatever the peasant asks for, his neighbor will get double.
The peasant, agonized, thinks on it all day. Finally he tells the angel "I ask that you put out one of my eyes".

Making Sure Our Lab Equipment Isn't Tricking Us

clovis again with the assumptions. (108 comments)

From the article:
The idea, essentially, is that if two quasars on opposite sides of the sky are sufficiently distant from each other, they would have been out of causal contact since the Big Bang some 14 billion years ago, with no possible means of any third party communicating with both of them since the beginning of the universe — an ideal scenario for determining each particle detector’s settings.

Why would you assume that if they're 14 billion years apart that it would be any different than 14 seconds apart in time, at least in regard to entanglement?
" with no possible means of any third party communicating" makes me think "we don't know of a means to communicate"
Could the outcome of the experiment could show either action at a distance, or some faster-than-light communication without excluding either possibility?
If it does happen that entanglement went away, it would be most interesting.
