  1. Re:Take a look around your house on Is Bad Customer Service More Profitable Than Good? (hbr.org) · · Score: 1

    tech leaders like Mark Zuckerberg are putting more money into personal security

    They have so much money the personal security budget is insignificant to them. Of course they are putting more money into it. From their point of view, it is a tiny cost and a major risk reduction.

  2. Sonic booms are not caused by crossing the barrier on NASA To Test 'Quiet' Supersonic Flights Over Texas (cnn.com) · · Score: 4, Informative

    "its prototype really will be barely audible when it crosses the sound barrier."

    Sonic booms are caused by going faster than the speed of sound. They are not caused by reaching the speed of sound. This is why the boom is a potential problem - it is heard along the entire supersonic flight path, not just at the beginning.

  3. Low income students believe what you said is true. That is why they get lower scores. In reality, knowledge of test taking strategies can help you score higher on standardized test questions. Often, you can get the points without knowing the answer if you understand how the test is (incompetently) constructed.

  4. No, they are not IQ tests.

    A correlation of 0.5 is terrible.

  5. No it's not an IQ test. That's false.

  6. Not true. The tests are biased towards Asian and White kids, because those kids have access to information about how to get high scores.

  7. U Chicago has staff whose job it is to know the quality of each high school. They can adjust. This is a super rich university, they can afford to pay for careful examination of these details. Many of the applicants are not even from the US.

    Most universities cannot afford those staff, but may have fewer high schools to keep track of.

  8. The University of Chicago is not really an educational institution. It's primary goal is to improve its own reputation. It does a lot of basic research. Undergraduate education is a side-operation. This is all about increasing the number of applicants, which increases the University's rejection rate, which raises its ranking.

    The empirical evidence is that diverse groups do learn and work better.

  9. "your standardized scores coming out of secondary education (high school, et al) mean everything, and can be relied upon to do so."

    Citation needed for the reliability. Can they reliably distinguish the top 8% from the top 9%? That is what U Chicago admissions needs to do.

  10. You're way off, U Chicago has offered BAs in science for many decades. I have one. And they are famous for being among the most rigorous degrees.

  11. Lots of things wrong with this post:

    1. They are not eliminating the standardized tests. They are just optional.

    2. If they are optional now, that means the scores were not actually being used in the past. Nothing is changing.

    3. Standardized tests are poor at measuring. They are particularly poor if you are trying to distinguish the difference between top 9% and top 8%, which is what they do at U Chicago.

    My email client does timeline and groups okay. What are the pragmatic uses of photo albums? Selling real estate?

    I would call inability to receive video an important feature.

  14. Re:it is called mail and email? on Ask Slashdot: Is There a Good Alternative to Facebook? (washingtonpost.com) · · Score: 1

    Right. As a non-Facebook user, I want to know what does Facebook do that email cannot? Pragmatic things, I don't care about games.

  15. OSTicket (GPL v2) on Ask Slashdot: Best To-Do/Task List Software? · · Score: 1

    I use OSTicket.

    It meets all your criteria, and it has a lot of features you probably do not need, which are aimed at large organizations. I use it to track multistep tasks. After a year's use it has not given me any trouble.

  16. Re:Mixed bag on Vermont Medical School Says Goodbye To Lectures (npr.org) · · Score: 3, Insightful

    "The medium that best suits a person's ability to learn varies a lot from person to person."

    This sounds like it's true, but it is actually highly controversial among learning scientists. There is very good evidence that people have well-established ways they prefer to learn ("learning styles"). The idea that teaching should be customized to match students' learning styles was originally promoted by a company that made money selling learning styles tests to schools. It turns out it is very difficult to prove if it works or not. And it's very expensive to implement.

    In educational experiments, alternative teaching methods nearly always work better than lecturing. I'm not aware of any evidence that replacing lectures with a thoughtfully-designed alternative has ever harmed a student's learning. It is common that students complain they have to work more when lectures are gone - but the extra work is the cause of the extra learning.

  17. Re:There will be no train on California's Bullet Train Hurtles Towards a Multibillion-Dollar Overrun (latimes.com) · · Score: 1

    You say "only well-off people will be able to afford" the train, but that's not the case in other places where there is high speed rail.

    I've taken them apart several times to change the battery. I don't think these are standard gaskets.

    Good, at least one person understood the question.

    Also, most smartphones do not work well while showering, swimming, or ice skating.
