    So if Windows is the least secure because is is the most used, the least used systems must be the most secure? Right? So things like BeOS, Amiga OS etc. are the best thing to migrate to for security!

  3. As a former intro to O-Chem Prof. on Should Organic Chemistry Be a Premed Requirement? · · Score: 1

    Seems like there are a lot of "As a this or that kind of student" posts so I'll address it from the non-student side. I taught both lecture and labs for O-chem and it is a very good intro for students to what an "intense" course is like. Lots of info in a short period of time. It was my job to make it relevant to the class as a whole so I covered advanced general chem (orbitals, bonding) followed by an intro to what organic is (classes of molecules) followed by several chapters on the chemistry of basic functional groups (learn the mechanism!). The next semester should include more functional group chemistry and a solid into to biochem. All of this is relevant as our bodies (the ones the doctors are treating) are basically doing complex reactions on complex organic molecules with all kinds of functional groups. They are prescribing complex organic molecules for us to take to improve our lives. I'd like my doctor to know the difference between a carboxylic acid and an amine, or a steroid and a opiate. Also - he should have some basic understanding of how any why these molecules interact with our bodies (please please please remember hydrogen bonding). I really don't want him to think of me as a black box and try things in a Edisonian manner.

    Also - its a great weedout class :P I got to see my students take exams (I was a nice guy - but some people STILL couldn't get half the questions right) and work in the lab. I had a low dropout rate, but the ones that did ALL told me they were premed and needed more time to get ready for hard classes. I doubt any will be back. I had several pass the course BARELY and decide medicine or vet school probably wasn't in the cards. What it boiled down to was effort. I had some OK students that did really well in the course simply because they put in the effort. They came to office hours (I begged!), they came and found me at lunch, they came to lab sections, they emailed me questions - they were not straight A students but they wanted a good grade in chemistry for the graduate applications. I didn't give them good grades because they were around so much - they got the grades because they asked a lot of questions about topics they were unsure of. Its a complicated science to learn and as hard to teach - some of the stuff is easier to grasp when a teacher is telling and showing you examples rather than reading it from a dry text book. There were a lot of kids in there that will make good doctors - doctors I'd go to, but the ones that didn't make the grade were not putting up the effort. Not the kind of doc you want to have.

    One more thing - biochem may be more relevant, but you need more than general chem to understand it. Organic chemistry is the basis of biochem. If you don't know what a carboxylic acid, amine, alcohol, etc. are, you won't understand the fundamentals of biochem. So even if you drop organic - its going to be covered in biochem. You cannot escape.

  4. Free SMS = $0.20 on AT&T Buries ToS Changes In 2500-Page Guide · · Score: 4, Informative

    Anyone else notice that AT&T sends you a notice of updated iPhone firmware that starts with "AT&T Free Msg: Apple has released ..." BUT when you get the bill - lo and behold you've been charged $0.20? I only notice this because I never use text messaging. I wonder if there is a way to disable this "feature" . . .

  5. Science also says it doesn't enter the bloodstream on New Study Links Plastics To Heart Disease, Diabetes · · Score: 2, Informative

    A Chemical Research in Toxicology article here stated that rats and humans handle bisphenol A in very different ways so I'd be careful drawing lines between rat and human results.

    "Enterohepatic circulation of bisphenol A glucuronide in rats results in a slow rate of excretion, whereas bisphenol A is rapidly conjugated and excreted by humans due to the absence of enterohepatic circulation. The efficient glucuronidation of bisphenol A and the rapid excretion of the formed glucuronide result in a low body burden of the estrogenic bisphenol A in humans following oral absorption of low doses."

    The article actually says humans basically excreet all of the material resulting in extremely low (near undetectable) levels of biphenol A or its metabolite. They fed humans 5mg of isotopicaly labeled bisphenol A and studied what the body does with it - there is no way any plastic bottle or cup is gonna deliver 5mg of bisphenol A to you via drinking or eating its contents. Bisphenol a is an anti-oxidant used in ppm levels in the plastic to keep it from yellowing over time. So IMHO the jury is still out - BUT my kids use BPA free plastics :) With kids why take the chance?

  6. Re:Hire a programmer. on Getting an Independent Project Started? · · Score: 5, Insightful

    So Ideas are like ***holes. Which means I have a lot of useless ***holes. I've set up a lot of sites that I thought were "great ideas". Set it up and they will come! Here's the development cycle so you can try it too:

    1) Light bulb happens.
    2) Register domain name.
    3) Brush up on MySQL/PHP again - pay particular attention to new functions needed but never used.
    3a) Drag out old projects with useful bits of reusable classes/functions.
    4) Spend a few weeks hacking around.
    5) Rewrite early sections of code that look bad after learning some new functions/technique.
    6) Upload the site to the "production server".
    6a) Make sure things are search engine friendly!
    7) Buy some adwords.
    8) Profit!

    This model works great up till 7). Costs about $0.25-1.00 per clickthrough so budget accordingly. Used to be $0.25 bought you the fist page of search results - no longer the case.

    I abandoned that model for another one:

    1) Use my and/or family/friends education + experience to develop an idea to address "mundane" needs.

    Boring needs are needs everyone has. i.e. the potential pool of customers is much much larger for mundane ideas than an idea that is an "agent of change" or "cutting edge" or "disruptive". Not saying you can't address mundane needs with disruptive tech - its just that the need had to have a broad potential customer base.

    2) Find someone to help me.

    This is where you get stuck - and the topic of the OP. Frankly I don't want an "outsider" working on the idea since once its done whats to keep you contractor from selling the idea/software himself? NDA/Non-compete agreements are useless - are you really going to invest your startup funds in suing a contractor? In many states they are unenforceable anyway.

    I had one proposal to develop a basic piece of HR software using a family members 30 years experience in HR. Posted a note on craigslist (I know not the best place) to see who might respond. I actually got a response from a really experienced IT professional and he and I were quite excited about the potential collaboration. We started to sketch out some code and immediately ran into a few road-bumps, mainly time-related issues. Anyway - the lesson is that as some posters have stated - execution is the problem - and generally the downfall of many small businesses. Ideas and talk are easy - finding an energetic partner that can coordinate his/her time and energy with yours is much harder. I don't have an answer really, but wanted to relate my experience. If I come up with a good way to solve this problem I'll repost it. . .

    The biggest problem I see is how will Apple handle the consumer expectation that the phone will be free in about a year, so just wait for it.

    "...basic research in applied engineering is still done in the US, without the pressure of money and immediate results?"

    So think biggest company (revenue wise) in the world. Even their corp. research demands results from basic projects. Corporate research in any company is now considered a Business Unit. ROCI must be maintained! The good old days are gone. When I joined said large company in the early nineties there were perhaps 2 or 3 famous research fellows in-house. By the time I left they had all moved on to academic jobs or startups. Nowadays you'll be lucky to be allowed to do some "side projects" in your career. Maybe spend a few days a month on it. The rest of the time will be meetings while your tech grinds out data. The up side is that you'd be surprised at how much you can expand basic knowledge doing things that academics consider "whoring your self out". Some interesting finds can be made exploring ways to improve products and processes. (and the pay can be pretty sweet) At this point in my life I might welcome an invitation from the Devil again....
