  1. Universal book standards on X-Prize Founder Wants Ideas For Fixing Education · · Score: 1

    I have recently returned to college and I have encountered a lot of waste in modern education. Almost universally the books are of poor quality and massively overpriced with companies spending more on marketing then on having the textbook be accurate and complete.

    What we should do is create at least a national textbook standard and have those books available to all students. So we would have one organic chemistry 1 textbook, 1 calc 3 textbook etc as part of a national standard. These standards would all be in ebook format and free for any student. I suspect this would save a few hundred million per year and it would be a fairly easy process to do.

    Right now though colleges tell you that you can use an ebook but they don't allow them on exams while physical textbooks are allowed. With a national standard we could have approved ereaders and no longer have this problem. We could eliminate a lot of environmental damage and energy usage by using electronic textbooks instead.

    In the end tax dollars are paying for most of the books anyways and a single textbook costs more than a kindle does and a kindle can hold many books. Each student could just be given a kindle and use it for college and we would save a lot of money and could get better textbooks or at least no worse then we have now.

    Mostly though the problem is that education is still firmly in the pen and paper world where teachers look at chalkboards and write down information for students to parrot back in an exam. Very little is done for actual understanding since testing memorization is far simpler. Until we move on to the idea that any fact you need can be looked up at any moment and instead test and teach to understanding education is going to continue to be pretty poor and turn out poor results.

  2. Re:GPU Performance on Early Ivy Bridge Benchmark: Graphics Performance Greatly Improved · · Score: 2

    The AMD llano chips are better then just competent for MMO games. A laptop llano chip will run EQ1, EQ2, WoW, The Old Republic etc without any discrete GPU.
    They even handle things like Fallout 3, Fallout New Vegas + lots of mods without needing a discrete card.

    The llano chips also do GPGPU without crushing your battery power. So if you are on battery power you can do calculations hundreds of times faster then an intel chip can if you can do GPGPU and not kill your battery doing it.

    For me I run into more and more things where the CPU is good enough but more GPU power would be better. For me llano hit a great sweet spot for a laptop.

  3. Re:Not all that counts on New Research Shows Cognitive Decline Begins At 45 · · Score: 1

    I read a study a while ago that the brain learns based on what we do with it and it physically adapts to the usages we have. As a result people have been declining in memory while increasing in reasoning since the brain is putting more physical structure into processing instead of remembering since facts can be looked up.

    Maybe this study is showing that once people are out of school the brain has learned that remembering is pretty much a waste of effort and processing is more important so the physical structure changes and memory is not as effective anymore. I know for some engineering work that doing stuff from memory can end up with criminal negligence charges if you screw up so there is a bias to look everything up all the time regardless of your memory. In a situation like that you will select against memory and for processing and as a result do poorly on a test like this without any decline in actual brain power.

    Cheating is massive at university, the design encourages it. Most classes are done as pure memorization classes and not on understanding. What this means is that cheating is actually encouraged behavior and cramming for tests works. I find this a truly horrible situation that needs to be fixed and even DARPA has commented on it but I don't see the universities changing.

  5. Re:trade school should come after not just college on Do Online Educational Badges Threaten Conventional Education Models? · · Score: 1

    However a lot of businesses require that piece of paper to do the work. DARPA recently did a study for STEM fields and what they found is that basically anyone that was capable of doing the required work after graduating college was also capable of doing the work on their own before starting. Very little learning actually happened but no company will hire as as an engineer without that piece of paper regardless of how good you are. Your resume will not even be looked at.

    The result is that colleges are essentially gatekeepers for many jobs and they do a poor job of preparing you for those jobs or much of anything else really. Colleges are still massively focused on memorization instead of understanding. Facts can be looked up and should be, understanding can not.

    Many in-person university classes are exactly what you said is wrong with online classes. Look at Organic Chemistry for instance, that one was even criticized by DARPA recently. Organic Chemistry classes in USA university are pretty much universally taught as memorization classes and tested that way also. Doing them online is no different then doing them in person.

    Last semester I had a class which did extensive online homework and it was not multiple choice at all. It was for a chemical engineering class on material and energy balances and we used something called sapling. For that you had to actually figure out the answer and enter them into the system and it was right or wrong based on how close it was to the actual answer. It worked extremely well and it helped learning since if you got it wrong it told you why it was wrong and you could try again.

    On the flip side I had a math class on differential equations and in that class maybe 1/3 of the homework or less was graded and many people ended up doing a certain type of problem wrong until an exam came since that type of problem had never been graded so they had no idea they had it wrong.

    Online courses and homework that are instantly computer graded offer a lot of advantages over poor university courses since you get instant feedback and so you don't learn the wrong way of solving the problem. Also you have to admit these online courses don't have to be better then good university courses they have to be better then poor university courses and that is a very low bar to meet since most university courses are poor.

    I would take good videos and online homework and tests based on understanding not memorization and not multiple choice any day over most university courses. If they where cheaper I would probably just do them for all courses since the odds of getting a good class is fairly low and at least these online classes would have a pretty standard level of quality.

    Also don't knock the khan academy until you have used it. I found it pretty essential on my differential equations class since it was done so poorly. The book did a poor job of teaching the materials and so did the instructor so without those online screencasts that class would have been vastly more difficult.

  14. Sounds pretty normal to me on How Many Hours a Week Can You Program? · · Score: 1

    My experience is that good coding does not work in large blocks over long periods of time. Productivity takes a nosedive pretty quickly at more then 4 hours or so in a day. I have run many tests on my code and others and so far my experience is that while you can keep writing code all day the code ends up buggier the longer you work on it and nastier to maintain later. Many times if I have a hard problem to solve I will just leave it for the next day since overnight almost 100% of the time I will dream up a better solution that will be simpler, faster, easier to write and easier to maintain. I have had to work with so many systems that where built by someone staying late and kept working on it that where so darn nasty to work with later and massively buggy.

    Mental activities are just not well suited to extended effort. There are too many things to go wrong as you start to get tired or can't see the entire picture of what you need to get the code working right. I also try to follow rules of keeping functions very short with well defined inputs and output and no tricks to speed things up unless actually required. Lots of functions where the output only depends on the input where possible are easier to debug later, easier to replace, easier to maintain and easier to make faster later then giant balls of code. I am not suggesting functional programming but some aspects of functional programming are good ideas for maintenance.

    Actually for Everquest and Everquest 2 this is incorrect. For the last 5 years or so the expansions have been inclusive. So if you buy whatever the most recent one it then you get all the content from everything previous. They have also been making it much easier to catch up with bonus experience until you get closer to where most of the players are. It actually is not as hard to catchup as you would think. When EQ1 first came out it took months to hit 50, you can now hit it in a week or two of fairly relaxed play. The mercenary system makes it much easier to solo and form groups. There are still 85 levels though and probably a thousand AA for EQ1 but I just recently went back and started on a new server and catching up has not really been hard at all.

    I think that all the older MMO will have to something like what everquest does to make it easier to come back.

    There is nothing the kernel developers can do about this. On my machine which is a dual 2218 opteron with Dual nvidia 8800gts video cards running 4 monitors just playing flash a single screen will bring one cpu core to its knees. Normal sized flash videos will bring one cpu core to its knees and will sometimes drop frames. The same video if saved to a local file and played with xine/mplayer etc will use up 1-2% cpu power at the lowest cpu freq (1 ghz).

    Linux is perfectly capable of smooth video playback at low cpu usage. It is flash that is not capable of that and nothing we can do about it. Flash is proprietary and only adobe can really fix it. If they don't choose to fix it then nothing we do is going to make those videos play any better. I am running the latest version of the flash player and it still does not play any better. Flash is a massive cpu hog.

    Kernel developers should work on solving problems they can actually solve. The Xorg and desktop developers should solve problems they can solve. All they can do is try and provide tools that flash can use to play videos better but since those tools already exist I don't see much that can really be done. Even on windows flash is a dog, netflix is a good demonstration of that. I am not like silverlight but it is massively faster at playing and at higher quality then flash is. An older system that could not play flash fullscreened at 800x600 from netflix can stream hd streams at 1600x1200 with no slowdowns at all with the silverlight player and low cpu usage.

    Adobe needs to fix it. Nobody else is to blame for it and nobody else can fix it.

    Seriously it depends on how fast the audio stream you are trying to get is. If you are playing really high bandwidth audio it would start skipping since you would not be receiving the data fast enough, however that is very unlikely since audio is very very low bandwidth. The vista problem degrades hundred megabit cards down to a few megabits which is still way more then audio streaming needs. So it should work just fine, just don't try to transfer a few gigs of files over the network to your fileserver since that will take a long time while audio is open.
