  1. Loyalty to any company is bullshit. on Ask Slashdot: When Is It OK To Not Give Notice? · · Score: 1

    Your relationship with your employer is a business relationship. They don't regard it as anything else; you shouldn't either. The minute they fail to meet their obligations under your employment agreement or contract, you should terminate it. Don't feel bad. They won't feel bad about terminating your employment on a moment's notice.

    The only way things will change is if companies that dump people start having a hard time hiring people and that will most likely be because people who get dumped warn others not to go there.

  9. My greedy, overpaid, dentist ass on How Outdated Data Distorts Doctors' Pay · · Score: 0

    You're neglecting a fundamental difference between being a healthcare provider and other professions such as IT.

    In many healthcare situations, we make irreversible changes to another human being that if done incorrectly can result in serious consequences, up to and including loss of life. It takes many years of preparation and personal sacrifice to reach a level of knowledge and skill that allow one to be granted the trust and privilege to perform such work. Yes, we are paid a bit bit higher than some other professions, but much less than many others. Some of my classmates incurred debt of >$300k to get through dental school, at 6.8 - 8.5% interest to be repaid in 10 years. For many that is >$3000 per month in student loan repayment.

    I don't know where you get the idea that dentists are overpaid or greedy, but I am sorry you feel that way. I think you may be a victim of the insurance industry's attempts to put the blame for high healthcare costs on the providers. This works for them as they try to drive down their payments to providers because that increases their profits. Provider fees are actually a small fraction of the total cost of healthcare in the US.

    If you think healthcare costs too much, I suggest that the next time someone presents you with a petition in favor of a single-payer system you consider signing it. I know, Rush (or Hannity, or O'Reilly) told you that that would be "socialist" or "big government" so it's bad, but consider this: the insurance industry exists to make profits. They do that by a) raising premiums that you pay for care and b) denying payment for the care you receive (and paid for). They have no incentive to deliver any health care whatsoever and employ armies of lawyers to lobby congress and state legislatures to maintain their grip on your wallet. A single payer system tasked with delivering healthcare would employ an army of people whose jobs are to ensure that payments are going to delivery of healthcare and not fraud. In either system you employ an army, in the former, the army works against you, in the latter the army works to make sure payments go to healthcare and not fraud. The latter situation sounds a LOT better to me.

  10. I'm not a gastroenterologist but I am on How Outdated Data Distorts Doctors' Pay · · Score: 5, Informative

    a dentist, and even I can tell you there's more to the story here. That 75 minute colonoscopy is probably an average. No one can predict exactly how long any given procedure will take on any specific patient. If a patient has no polyps, the procedure goes faster. If they find polyps and remove them (that's how colonoscopies prevent cancer) it takes longer. Patient anatomical variations and other medical complications can affect the time required.

    I run into the same thing with my patients. A simple 15 minute restoration on a cooperative adult patient can turn into an hour long ordeal on an uncooperative 5 year old, but insurance pays the same for either one.

  17. Having designed and built my own 3D printer on Breaking Up With MakerBot · · Score: 2

    I would tend to agree with Mr. Kleinfeld. 3D printing is a tweaky, fiddly process that requires a lot of time, energy, and specialized knowledge to get to work properly. The machines are finicky, the software requires far too much knowledge of detailed printer specs and the raw materials that feed printers are produced with little or no quality control resulting in unpredictable performance from the printer and frequent recalibration.

    The printer designs are not particularly well done either, especially the bed leveling. Most use screws at the corners of the bed to do the leveling. That makes no sense as anyone who has had a geometry class will tell you. 3 points define a plane. Since one point can be fixed, there need only be two leveling screws. That is what I designed into my printer and it works perfectly. One screw adjusts tilt along the Y axis and the other adjusts tilt around the X axis and neither affects the other. Leveling took about 1 minute and now I can completely remove the print bed and replace it and never have to tweak the settings.

    My printer is designed to print big(ish) stuff. The print bed is 300x300mm and vertical print capacity is 280mm. I designed it so that I could print full-sized human skulls from CT scan data. If you're going to print big stuff you have to have everything working reliably. I ran into the extruder problem early on and have been working on that for a while.

    There seems to be two problems with extruder failures. One is the variations in quality of the filament and the other is in the design of the extruder itself. I can't do anything about the quality variations in the filament but I can make changes to the extruder design to make it more immune to those variations. My original extruder used a gear on a stepper to push filament into the hot-end. I found that the filament would often got hung up in the hot-end and the extruder would keep trying to push and the gear would carve a divot into the filament assuring that the extruder could never push that filament again. It is notable that I have never had the nozzle actually clog- every time the extruder has hung up I have been able to manually push the filament and have it come out the nozzle. My reedesign mimics a wire feeder in a MIG welder and uses two steppers to push the filament. Preliminary tests indicate that it is working, but further tests are ongoing.

    And insecticide and iced tea both contain water, yet they aren't really very similar, are they?

    You're overlooking the biggest difference between the CRT and the x-ray tube. One is designed to produce short wavelength radiation, in abundant quantities, and the other is designed to produce meaningful, controllable patterns of light and just happens to produce a very minor amount of X-ray radiation. I'll leave it to you to figure out which is which. No, they aren't similar at all.

    That's like saying herbicides and insecticides are almost the same because they both contain water.

    The differences between a CRT and an x-ray tube are not at all subtle. OK, they both have filaments to boil off electrons and both use a high voltage to accelerate them, but so do certain types of amplifier tubes and some types of particle accelerators.

    If you do a quick web search you can easily find out just how different they are.
