  1. Another good example of measuring the wrong thing on Discouraging Students from Taking Math · · Score: 1

    This reminds me of the situation when I graduated High School. My best friend filled her schedule with all AP courses, had not study halls, etc. I took what I had to, AP courses that interested me (math and physics), and things like drafting and small engines, and made sure I always had a study hall.

    At the time in Wisconsin the top two students at each school got full state scholarships. According to the school she was ranked #2 and I was ranked #6, because the school weighted AP courses at 4.5 and gave you a higher ranking for more quantity of credits. Big surprise at the end of the year when the school let us know that the state ranked me #2 because it just went off straight grade point average. She had to give the salutatorian speech, but I got her scholarship from the state. Surprising she's still my friend :)

  2. Cost of forgetting to change the seat position on Economic Analysis of Toilet Seat Position · · Score: 1

    What has not been factored in is the cost of Marsha or John forgetting to change the seat position before performing toilet operations. The scenario would be John attempting to perform #2 or Marsha performing #1 or #2 with the seat in the up position. This generally happens (at least in my house) because the user is still half-asleep or their senses are otherwise dulled. The probability of this occurring is much much lower than p, however the cost to the user when this happens is much much higher than the cost of a single change-the-seat-position action. The cost of the yelling from Marsha is (again in my experience) also much much higher.

    There is also the inverse, where John forgets to raise the toilet seat before #1, often for the same reasons as above. Again the probability is lower and the cost (either of needing to clean the toilet seat or of yelling from Marsha when she sits on a wet seat) is greater than the costs of changing the seat position.

    In any case in my house the game includes a 5 year old boy who generally waits till the last second and then runs into the bathroom doing the potty dance, and doesn't remember to raise the toilet seat for #1. The resulting mess I think now even has my "Marsha" raising the toilet seat after use in anticipation of this activity.

  3. Re:Turbo Tax: Pain in the rear on Turbo Tax Melts Down on Tax Day · · Score: 1

    Wow that is very expensive.

    I've been using TaxAct since like 2001. I spend $19.95 to download the federal and one state module, and the $19.95 includes one free Federal electronic filing. And I think it would have been under an additional $10 to file my State online as well (I'm too cheap though, so I mailed it.)

    I've heard that they audit a higher percentage of electronically filed returns, presumably because its easier/the cost per audit is cheaper for an electronically filed return, but I don't know if any of that is true.

  4. Real information from the people working on this on Are Mobile Phones Wiping Out Bees? · · Score: 3, Informative

    If you read the FAQ from the Colony Collapse disorder working group you'll find that Genetically Modified Crops and Cell phone Radiation are not likely causes:

    "What are examples of topics that the CCD working group is not currently
    investigating? GMO crops: Some GMO crops, specifically Bt Corn have been
    suggested as a potential cause of CCD. While this possibility has not been ruled out,
    CCD symptoms do not fit what would be expected in Bt affected organisms. For this
    reason GMO crops are not a "top" priority at the moment.

    Radiation transmitted by cell towers: The distribution of both affected and non-affected
    CCD apiaries does not make this a likely cause. Also cell phone service is not available
    in some areas where affected commercial apiaries are located in the west. For this reason,
    it is currently not a top priority.

  5. Re:Scientology isn't a Religion on Scientology Critic Arrested After 6 Years · · Score: 1

    As a former Christian and current closet Athiest, I see Scientology as a religion just as much as Christianity, etc. (although much newer).

    Both religions provide a purpose and guidance for behavior for people who need these things outside their own personal experience, who need something to strive for and believe in.

    However I see one key element that for me says that Christianity is good and Scientology is bad -
    Christianity is based on selflessness - you are taught that the meek shall inherit the earth, to give even if you have little to give, etc. This is why it is desireable for the 95% of the population that have 5% of the wealth.

    What I hear of Scientology is based on selfishness - its OK to gain wealth. Its Ok to spend your time and your wealth on yourself - moving up within the different levels of Scientology. This is why its desireable to the Hollywood types, and the rest of the 5% of the population that control 95% of the wealth. A religion that makes them feel guilty for being wealthy and not sharing just isn't desireable for most of them.

    - A weaving loom (not a real fancy one)
    - A MAME cabinet. OK, so I didn't finish the whole cabinet, but I did build the controller.

    Yeah, mine is a telescope too- 12.5 inch "Obsession" style truss-dobsonian. Actually I just recently finished it. Bought the primary mirror off E-Bay, and another $200 worth of parts that I didn't have in my basement mostly off the Internet, the book "The Dobsonian Telescope" by David Kriege, and 3 months later I'm ready to take it out for true "first light" the next clear night.

  9. Flawed encryption schemes on Why Not Use Full Disk Encryption on Laptops? · · Score: 2, Interesting

    There is an inherent flaw with many of the commercial laptop full-disk encryption solutions out there. I have the most experience with Utimaco's Safeguard Easy, but I know many of the other big players have the same fault -

    The software has a feature called "Pre-boot Authentication", by which the encryption software is loaded after the bios, but before the (generally Windows) operating system. The user's password is used to generate the decryption key, so theorhetically not even the NSA could decrypt the laptop without the user's password.

    Here's the flaw - the software has a checkbox to disable Pre-boot authentication. What this does is generate a default user with a random password, and then store this random password obfuscated but in clear-text in the same disk area decryption software. When you talk to the sales-people, they sell this as a feature, in fact about half of Utimaco's customers (so I'm told) run it in this mode because the encryption becomes transparent and it is much less intrusive on the user. (Basically the disk is automatically decrypted each time the laptop is booted, but you have to have a valid Windows login to get in.) Buried in the help documentation are warnings "For security reasons, you should Never disable pre-boot authentication". So the engineers and the company know the weakness of disabling pre-boot authentication, but they don't tell their customers when they sell the software.

    Today it seems to break into these laptops with pre-boot authentication disabled you would need somewhat sophisticated tools and techniques, basically the same tools and techniques people commonly use to "crack" commercial software today. But I'm guessing that it won't be very long before someone takes the time to build this crack and releases it, rendering the laptop encryption useless to anyone who can Google for "Utimaco Crack", etc. Basically all the crack would need to do is grab the default user's password off the disk and use or duplicate the decryption algorithms that are also in clear-text on the disk.

    I've talked to a number of IT security folks, and basically it seems like most people trust the sales folks and don't understand that its basically impossible to have strong encryption without having the decryption key stored off the disk (like on a smart card, or in the brain of the user.)

  10. Value of an MBA on Is Graduate School Useful in Today's World? · · Score: 2, Interesting

    I received an undergrad in Physics and Comp Sci from a liberal arts college, so I thought I was pretty well rounded. I then went into various development, network management, and eventually IT leadership positions. I started pursuing my MBA thinking it was basically going to be busy work to prove to others that I am ready to move to the next level (a leadership position outside if IT). Some of it is busy work, but there is real value to much of the content, even though I've been a do-er and a leader in corporate America for a number of years. I'm about half way through earning my degree, and I've already learned a lot that will help me attain and be successful at the next level.

  11. Re:in other news.... on OpenOffice.Org in a Corporate Environment? · · Score: 1

    This is so wrong. For $65K, there is no bargaining with Microsoft.

    For a corporation of this scale, you really have three options:
    1. - MS Select Level "A" - You commit to buy a certain amount of desktop application software each year for the next three years, and you will get a slightly better price than the standard (Open) license cost. You can choose to purchase this with or without software assurance - basically paying a 30% maintenance fee to get free upgrades when new releases come out.
    2. - MS Enterprise agreement - you pay more than you would under select Level "A" with software assurance and get other preipheral benefits that aren't worth the extra cost.
    3. - Purchase retail upgrades rather than under a corporate license. You can save like 30% or more off the cost of the full corporate license. If you talk to your Microsoft rep about this, they'll tell you that you could do this, but no one would want to because you have to store each license and media, blah blah blah. Well, there are companies that are more than willing to store a few dozen cases of MS office retail upgrade boxes to save $100,000. And Microsoft knows this, because they know that a corporate VAR wouldn't be purchasing 900 retail boxed office upgrades in one shot for their (non-existant) retail client base. Microsoft keeps an absurd number of retail boxed upgrades in their warehouses because more companies than you would think choose this route.

  12. Perspective from a current online student on Online vs. Traditional Degrees? · · Score: 2, Interesting

    I'm currently enrolled in an online MBA program, a couple of my observations:

    I received my undergrad physically present at a liberal arts college. After freshman year, I think you get a lot more valuable stuff out of college than just the knowledge you gain in class (things like social skills, teamwork, and communication).

    However if you've been working as a knowledge worker out in the world I think you get enough experience/practice with these in your work, and will not gain the additional benefits of getting this experience in school as well. In this instance, there are a lot of benefits to the online degree: Fits into your schedule, you don't have to sit through a class that goes at the pace of the slowest learner, etc.

    Another aspect of the online degree - at least in the classes I'm taking - you are forced to participate and provide original insights throughout the class. Most of this is in the form of threaded discussions, which are monitored by the professor, and which you must post to to receive credit. In a lot of physical classes, as long as you do the homework you can sleep through class and never participate.

    In fact, I think for some of my online courses I put in more time than I would if I had to show up and listen to the professor for four hours a week.

    I'm attending Keller graduate school. For any of the courses I'm taking, I can choose to take it online, or I can choose to take a physical class at one of the local campuses. I'm pretty sure the "degree" (piece of paper I'll file away and never look at again) doesn't differentiate itself whether its online or physical.

  13. I've always thought this to be the case on Students Do Better Without Computers · · Score: 1

    Computers make problem solving easier, and the human has to think less when solving a problem with a computer. When you are learning, the goal is to think more, not to solve the problem as quickly as possible.

  16. Are non-IT workers are just less happy at home? on The Unhappy World of IT Professionals · · Score: 1

    Is it possible that one thing that could impact the rankings is the quality of home-life relative to work-life. IT workers on average are paid higher. They likely have less stressful home lives (i.e. not worrying as much about paying bills). They also have more money for non-necessities like toys and travelling.

    So IT professionals may be unhappy with their work life because they are more "spoiled" and have more desire to be living their home life.

  17. Useful for dams on salmon streams/rivers? on Digital Camera Could Help Sort Fish, Save Stocks · · Score: 1

    I saw a PBS special some time ago on salmon migration. There are special "fish ladders" that allow the salmon to swim upstream around the dams. On many of the ladders, they have an area where fish swim past a window. People sit in front of these windows and count each type of fish as they go past.

    I wonder if this technology has replaced that process. I also wonder how effective it is at separating different breeds of the same type of fish. (If I remember there were many different "breeds" of salmon, that were just slightly distinct visually from eachother)
