I've been on low carb diet for just under a year and lost 112lbs and haven't had to do anything else yet, just avoid sugars and carbs. Just get results from the lab and all the tests they took look fine, so the diet is fine that way too. I don't think there is anything that special about eating low carb, it just is fairly difficult to get too many calories per day without carbs.

Webster was wrong, you never ever should exploit a system you don't own or are hired to pentest. If you find a security hole in a server and they don't respond, you should just go public with the exploit and most likely let someone else to hack the system for you.

So that means 90% accurate tests will correctly identify 425 non-Alzheimers cases, miss 5 cases, detect 48 Alzheimers cases and give out 47 false-positives. So in this case when the test flags you, there is 50% chance that you are false-positive.

Think about pregnancy tests. If it shows positive, you most likely are. If it's negative, there's chance you might still be pregnant.

And your example is of a test that has false positives and false negatives.

The OP is right in that the 90% accuracy is not very useful until we know how common Alzheimer's is in the population taking the test

Good example of this was 99% accurate HIV test if it is applied to random sampling of all people. As HIV is so rare, if 100.000 people take the test, it will flag 1.000 as having HIV even when don't and correctly identify 10 real HIV cases and miss 1. (numbers pulled from memory and probably not accurate)

Comment Why sell mining rigs? (Score 3, Insightful) 250 250

This one puzzles me somewhat. If one can make money by mining with ASIC rigs, why would anyone sell or rent them, wouldn't they make more money by mining? If they make more money by selling or renting, then wouldn't that mean that mining is silly?
