    So ban electronic devices from making sound on an airplane for "safety reasons". I.e. mandatory vibrate mode and/or headphones. That has at least some basis in truth and still allows people to sleep/relax without keeping us from our e-mail.

  2. Honestly, I could go on about how much money and effort is really involved in supporting what is currently being advertised and sold to customers as "unlimited", but at the end of the day this is about false advertising. If you sell "unlimited" without any caveats and then renege without consideration for your customers you should be sued.

  5. Re:Considering sub queries in IN statements. on Oracle Claims Dramatic MySQL Performance Improvements · · Score: 5, Informative

    You're probably right, but that's not what this release is referring to. The NDBCLUSTER engine separates "API" nodes from Data nodes. A server running MySQL with NDBCLUSTER enabled is considered an API node, but you can also have a C++ or Java or whatever API node that isn't MySQL. Data nodes are provisioned in one or more "node groups" with one or more data nodes in each group, though it would be dumb to have a single node group or a single node in a node group. Each node group splits the data somehow. You can force tables to exist on just one group, but by default if you have three node groups you would have approximately a third of your data in each group.

    Anyway -- prior to NDBCLUSTER 7.2 if you performed any join whatsoever the API node had to pull the complete tables from all data node groups prior to doing the join on itself and returning the result. This made join performance, simply put -- terrible. I've tested the same query on a standalone out of the box mysql server against a 7.1 cluster and had an 8 second query come back from the cluster in several minutes due to the join performance.

    NDBCLUSTER 7.2 adds what was called "push down joins" in development -- basically the data nodes now do the joins within their own sub-sets of the data for certain joins resulting in a dramatic improvement in performance, since now the API nodes just get the result from the network instead of the entire dataset.

    It really is an amazing improvement and is a result of the dynamic capabilities of MySQL. NDBCLUSTER was never designed for the type of data people are throwing at it, and with the recent improvements it might actually be viable for use on production web sites for more common usage scenarios.

    What I do not see addressed yet with 7.2 is the reload time -- if you have a cluster loaded with several GB of data it can take upwards of 20 minutes to reload the data and indices across the cluster. While the cluster is designed to be up 24x7 (even through upgrades), a single bug or memory error that takes it down can result in a prolonged outage. There are several of these open in the bug tracker.

  6. Re:Compared to what? on Why Android Upgrades Take So Long · · Score: 4, Insightful

    Android is free and newer versions tend to not only work better but provide more features. Windows upgrades tend to consume more resources and generally introduce new bugs. It's not really fair to compare the two. That being said, it would be a completely different story if your new PC came with the promise that newer versions of windows would be made available at no charge over your existing internet connection. Why shouldn't you be upset when a new version is released and months go by without your upgrade coming through?

    Wow, I already knew that people on Slashdot had a very tenuous understanding on economic or scientific topics, but damn, most of you have an awfully tenuous grasp of statistics too! ...If it should, then it's not for the reasons you're thinking of.

    Perhaps you could enlighten us with your genius. God forbid anyone has an opinion who doesn't have a PhD, right?

    If you open your eyes and ears, some of the best ideas can come from people who sound like they don't know what they are talking about. No, I'm not going to go looking for examples for you, but I've seen enough idiots with advanced degrees on the news and the internet to realize it's prudent to listen to people who have something to say and not judge so quickly.

    Yes, I responded with enough haste that I didn't stop to think of everyone who would be offended by my lack of statistics training. My sincerest apologies.

  18. Re:Inspiring.... on AIDS Vaccine Is Partially Successful · · Score: 0, Redundant

    I was thinking the same thing. If they weren't tracking and testing all sexual partners I do not understand how they could come up with any statistically valid result. It seems that they are making a lot of assumptions as to the common behavior of all of the subjects. Considering how small of a percentage actually became infected (51 out of 8000 is about half a percent), I don't see how any assumptions could "even out" with the sample pool.

    This news is certainly exciting, but IMO it should be taken with a grain of salt.

  21. Re:Actually on Musician Lobby Terms Balanced Copyright "Disgusting" · · Score: 5, Informative

    School bands, the orchestral and marching bands, all did the same thing until Xerography became commonplace. Now I suspect they buy ONE copy and burn as many copies as they need.

    That would be a copyright violation, easily.

    Some do that. Most of them actually purchase the music because the RIAA and similar groups have enormous fines for not having the originals. There are 800 numbers you can call to report suspected piracy and they will come out unannounced and search the school's music library to make sure they have purchased originals for all of their music.

    Since kids tend to damage or lose the originals many directors keep them in their library and only hand out the photocopies -- which is entirely legal.

    A side effect of this is why school music programs are always broke. They have to spend a lot of money on the music alone, and whatever is left over goes to instruments, uniforms, and eventually the students. IMO this is good example of everything that is wrong with the industry. Schools should get this stuff for free so they can spend the money on education and not have to worry about copyright.

    I think the problem that they have, is a loss of control over the information.

    If something goes wrong, intentional or otherwise, and the schedule that all these people look at through the phone is incorrect... who's gonna get the angry customer call? The train company.

    That's the first thing I've read here that actually makes any sense as to why the MTA would be doing this, though I adamantly disagree. As was previously stated, this is the city transit authority -- by definition a public entity. They have no business doing anything with copyright, nevermind suing a tax payer for using the information!

    This is almost as bad as the news that the tax payer "bailed out" banks are raking in record profits by increasing overdraft and other fees -- talk about biting the hand that feeds you...
