Apple's App Store Needs a Radical Revamp; How Would You Go About It?

MobyDisk Re:If the 12% spend more (249 comments)

Some of this is confirmation bias: I have free ad-supported apps on my phone and there is no option to pay to eliminate the ads. Another reason is the plethora of free and free/OSS apps

About Half of Kids' Learning Ability Is In Their DNA

MobyDisk Re:Meaning (227 comments)

So, these studies probably mean it isn't a fundamental ability problem, so where do I go from here?

The article doesn't actually say what the summary says it does. It does not say that your ability in math and reading is equal.

About Half of Kids' Learning Ability Is In Their DNA

MobyDisk Dumb summary: Reading and Math are not equal (227 comments)

The Slashdot summary draws a conclusion that seems unsupported by the paper:

You may think you're better at reading than you are at math (or vice versa), but new research suggests you're probably equally good (or bad) at both.

But the paper says otherwise:

The genes that determine a person's ability to tackle one subject influence their aptitude at the other, accounting for about half of a person's overall ability.

So your score is 50% correlated, not equal. That is a really important difference! If the paper said people were equally good at math and reading, that would be a startling conclusion!

About Half of Kids' Learning Ability Is In Their DNA

MobyDisk Re:Correlation not Causation (227 comments)

They have not shown a causal relationship.


This indicates that if there is a genetic component, it is largely irrelevant as the learning environment has the greater impact.

False. I'm unclear how you came to that conclusion based on the quote you highlighted. It does not say that learning environment has a *greater* impact. It says learning environment has *some* impact. Overall, but it is less than or equal to the importance of genetics.

This result is consistent with other studies on the topic. Unfortunately, this fact pisses people off, especially educators. (Understandably since it is their job to educate everyone equally, and especially to raise the level of the poorest performers). But it is well correlated at this point. Think back to high school: everyone realized this at some point - there were some students who just seemed smarter. Some of them didn't even have to work for it. It sucked if you sat in one of these kids' shadow. It doesn't mean hard work doesn't pay off, it doesn't mean you should not invest in your children, but it does mean that just like in sports, your genes are as big a contributor as the environment.

On that note: why are people willing to accept this in sports, but not in academics? It's totally cool to say something about Nigerian runners having long legs, or say "white men can't jump, hahaha" or "Asians are short" but if you say some people are genetically gifted in intelligence sets off everyone's alarm bells.

Excerpt from Freakanomics:

Eight factors that correlate to higher test scores
        Highly educated parents
        Parents have high socioeconomic status
        Mother was thirty or older at the time of first child's birth
        Child had low birth weight
        Parents speak English at home
        Child is adopted
        Parents are involved in the PTA
        Child has many books in the home

Eight factors that do NOT correlate with higher test scores:
        Family is intact
        Family's recent move to a better neighborhood
        Mother did not work between birth and kindergarten
        Child attended Head Start
        Parents bring children to museums regularly
        Child is regularly spanked
        Child frequently watches television
        Parents read to him nearly every day

TEPCO: Nearly All Nuclear Fuel Melted At Fukushima No. 3 Reactor

MobyDisk I think this means (255 comments)

fuel at the No. 3 reactor began melting at 5:30 a.m. on March 13

I think this confirms that that they should not have flooded the reactor with seawater because the meltdown had already happened by the time they made that decision. They flooded the reactor on March 15th, as a last ditch attempt to prevent a meltdown. But it was too late to save the reactor since the fuel was already completely melted. So all the seawater did was let more nuclear material escape.

Or, alternatively, they should have flooded it with seawater days ahead of time. The tsunami was March 11th, so perhaps had they made that decision on March 12th it would have been in time to prevent the worst of it? Ehh... maybe not.... the reactor foundation was probably already damaged by that point. :-(

How Many Members of Congress Does It Take To Pass a $400MM CS Bill?

MobyDisk Re:Stopping the race to the bottom (180 comments)

Does this effort solves the fundamental problem that you bring up? Kids aren't interested in these fields because they are hard and mathy. American society does not value those things. I bet you could get more kids into CS by teaching them shop than by teaching them CS. Like you say: Society has to value BUILDING. Reinvigorate that first.

Ask Slashdot: Should I Fight Against Online Voting In Our Municipality?

MobyDisk Don't wait for an issue to become a national one (190 comments)

The best way to fight these things is on the local level. It's tough to convince 10 million people why it is wrong. Much easier to convince 10,000 neighbors. By the time a state or country wants to implement this, it is too late.

Ask Slashdot: When Is It Better To Modify the ERP vs. Interfacing It?

MobyDisk I agree with the CIO (209 comments)

You don't want dozens of applications that interface with the ERP system. If you do that, when the ERP interface API changes you now have to change dozens of applications. The ultimate result of that is that the ERP system upgrade cost now goes through the roof. 10 years laster, someone is going "You are using version *WHAT* ?!?!?! It only works with Internet Explorer version *WHAT*?!?!?!" I've been there! You also now have to train people how to use each of those applications.

Hackers Plundered Israeli Defense Firms That Built 'Iron Dome' Missile Defense

MobyDisk Re: Tag, you're it! (184 comments)

Since you seem the first person who actually might know what these conventions say, can you explain something to me?

There is all this talk about Hamas using "human shields" and I want to know how that works. Let me make it easy by being extreme: Suppose country A duct tapes babies onto tanks then attacks country B. What response is permitted by country B? Is country A violating the geneva conventions? Would country B violate the geneva conventions if they returned fire?

I know that example is silly, but I think it is a solid place to start. I keep seeing allegations, videos, etc. of Hamas placing children near rocket launchers. So if Israel responds by destroying those rocket launchers, thus killing the children, who is the war criminal?

Gaza's Only Power Plant Knocked Offline

MobyDisk Re:child casualties (868 comments)

What part of "there is no place in Gaza away from civilians" did you not understand?

Did you watch the video? Is Gaza so crowded that the only place for kids to stand is posing, smiling, 5 feet from a rocket launcher while adults duck and hide? Because that is what the video seems to show.

But that is also why I wanted someone to clarify the video. It shows a bunch of kids, standing almost like they are posing for a photograph, next to some large black piece of equipment. What is that piece of equipment? Why did the adults ducked down a stairwell or whatever that was. What was it? What is with the guy hiding behind the truck?

3-D Printing Comes To Amazon

MobyDisk Re:Little Appliance Parts (62 comments)

No, this is the essence of nerd. And maker. No need to strip you of your card.

The hard part is that you have to design it yourself. Sinec you call yourself a nerd, I recommend downloading Blender or OpenScad and give it a try. Just send me the STL file and I'll happily print it for you. You can find me, or any of my clones, at your local hackerspace.

MobyDisk writes "Network Performance Daily retracted last week's interview with Professor Christopher Yoo from Vanderbilt University Law School on his opposition to Net-Neutrality policies. The new article is clearer, more subdued interview. The editor, Brian Boyko, says he never received Mr. Yoo's corrections to the article. From the apology: "The article had done him a disservice and resolved to repair any inaccuracy or anything that would be unfair to his words or image." Lost corrections, or a revision in response to criticism?

Last week's article now points to an series by Art Brodsky, Communications Director of Public Knowledge that is in support of Network Neutrality."
