    You did read http://dbaron.org/mozilla/visited-privacy right? It was linked to from the article mentioned in response to the comment you cite.

    The short of it is that layout.css.visited_links_enabled is still true so _you_ get to see the visited links styled differently, but the website is blocked from being able to tell apart visited and unvisited links. And yes, every single Firefox 4 beta has had that fix, including this one.

    I assume that's with a clean profile (or at least one without extensions) and that you're using the Firefox 4 beta, right?

    On Windows Vista/7, there are some existing dwrite issues being worked through where trying to initialize the dwrite library will go and read all the fonts on your operating system in their entirety; issues that are partially fixed if you install the updates IE9 requires and partially being worked around on the Firefox end for Firefox 4; those patches aren't done yet.

    Also on Windows it's common for OEMs (and things like Skype!) to install system-wide Firefox extensions that severely impact Firefox performance. That's being worked on too. I sort of assume you checked for this possibility already.

    If you're not on Vista or Windows 7, I'd really appreciate you reporting a bug about this to Mozilla and ccing me (put the string ":bz" in the cc field). It should be quite possible to measure what's going on during those 30-45 seconds and figure out why you're seeing slow startup when others aren't. It's pretty late in the game, but we might be able to fix whatever is causing you problems before final!

  3. Re:How many are paying sticker on Is Going To an Elite College Worth the Cost? · · Score: 1

    Sort of.

    If you look at http://www.finaid.org/calculators/finaidestimate.phtml and select the "Institutional Methodology" (which is what the elite schools use), 4 person family, 1 person in college, MD as the state, 55 for older parent's age, $120k AGI, $18k federal tax paid (it's about the right ballpark for that AGI given no weird deductions), $120k for father's earned income, $20k in a rainy-day savings account, zeroes for everything else for the parents except home equity, but assume the house is paid off so there's $300k of home equity. Assume the student also lives in MD, is 18, and has no money at all.

    Estimated family contribution: $40103 per year.

    While this is only 2/3 of "sticker price" if you include room and board and other things they estimate at Harvard, say, it's more than the yearly Harvard tuition.

    Note that $300k is about 50% below median for the close-to-DC counties of Maryland, by the way. And that the home equity number is influenced by how much your home is assessed at, not anything tangible. So it can just drop when the housing market drops.

    Had this family, or just the student actually had any savings, they would be paying a good bit more (12% of parent assets; 20% of student assets; both per year).

    Now things are definitely changing; ten years ago I could have made the income way lower and gotten similar numbers, but now there are some income cutoffs below which the institutional methodology no longer considers assets. Which means that it may well be worth it to quit your job or get a much lower-paying one as your kids go to college, depending on the state of your home loan and your bank account.

    Of course if I modify the example to have zero home equity the EFC drops to $25230....

    All of which says that the only people who pay sticker for the elites are those who are stupid or uncaring about money enough to have actually saved some money and to still have jobs while their kids are in college.

    Whether this is a good incentive system is an open question.

    They tried to set a standard video codec.

    Opera and Gecko refused to implement one of the possible contenders (H.264) for patent reasons. Furthermore, H.264 doesn't comply with the spirit of the W3C patent policy, though it does comply with the letter (because while a W3C spec can't require implementation of a W3C-designed techonlogy that has W3C members holding patents on it and not licensing them, it _can_ require implementation of a patented technology developed by someone else, via citing it by reference).

    Apple refused to implement anything other than H.264.

    Yes, and "computed experience" is not all that hard to define (in various ways, agreed) and then measure.

Now you can accuse me of being insufficiently pedantic in that I didn't define such a measurement technique, but that's where the fact that in this case it really doesn't matter much comes in.

    > But saying Mr X is the mode of Lalaland is just retarded.

    When measuring somewhat imprecise quantities (like "computer experience"; this is less applicable to salaries) it's common to deal with the imprecision by binning (e.g. instead of asking people for the exact to-the-second amount of time they've programmed in C, whicih they couldn't tell you if they tried, you ask them for the number of years, possibly with some predefined non-single-year ranges). At which point it does in fact make sense to speak of the mode of the resulting distribution.

    But as an aside, you could in fact talk about the modal salary. It's just not a very useful measure when binned at the 1 cent level, so no one does.

    Again, I could have been more pedantic and said "The amount of computer experience you have is likely several standard deviations away from any of the mean, median, or mode amounts of computer experience in the population of grandmothers in the United States in the year 2010."

    Just to save you the trouble of reading it, if don't want to, it's pretty clear that IE9 is eliminating the heart of the math-cordic loop as dead code. It _is_ dead code, so the optimization is correct. What's weird is that very similar code (in fact, code that compiles to identical bytecode in some other JS engines) that's just as dead is not dead-code eliminated. This suggests that the dead-code-elimination algorithm is somewhat fragile. In particular, testing has yet to turn up a single other piece of dead code it eliminates other than this one function in Sunspider. So Rob filed a bug about this apparent fragility with Microsoft and blogged about it. The rest is all speculation by third parties.

    While there are no _federal_ laws covering some of those items, there are plenty of _state_ laws (e.g. a number of states have laws requiring paid maternity leave; several have required paid paternity leave as well). Further, there are federal laws requiring certain treatment of maternity leave (e.g. treating it at least as well as you treat any medical short-term disability). There are certainly federal laws against discriminating (though perhaps your definition of "discriminate" is different from the one in those laws?). Health and safety regulations clearly vary by field; I'd like to see your data on "few".
