Submission + - Canada may tax legal music downloads 3

FuriousBalancing writes: MacNN reports:

Canadians may soon pay a small tax on every legal music store download, says a new measure (PDF) sanctioned by the Copyright Board of Canada. Requested by the Society of Composers, Authors and Music Publishers of Canada (SOCAN), the tax would apply at least 2.1 cents to every individual song download and 1.5 cents per track for complete albums. Subscription download and streaming services would themselves be charged between 5.7 and 6.8 percent of a user's monthly fees. Minimum fees would also apply for every larger download or subscription. The new tax would be retroactive to January 1st, 1996.

Feed Science Daily: Does This Child Have Appendicitis? Watch Out For Key Signs (sciencedaily.com)

A 5-year-old with abdominal pain, nausea and fever may have appendicitis or any of a number of other problems. But how does the child's doctor decide whether to schedule an emergency appendectomy to surgically remove a presumably inflamed appendix -- a procedure that carries its own risks like any surgery -- or wait and observe what could be a ticking time bomb that could rupture and kill the patient in a matter of hours?

It's all the same, but one thing's for sure, we will radiate for weeks", today it became clear that he was referring to the resurrection of Suprnova. Article Here

Exposing Children to Technology? 466

LabelThis asks: "While I'm not a huge fan of immersing children in technology, there is a certain point at which you must expose them to the tools that will help them be successful in the world. Looking back, I distinctly remember my parents making every effort to provide a computer for me and my sibling, early on (they bought an Atari 400 for us when I was 5). Either by accident or on purpose, that single decision (and the continued follow up of purchasing newer computers as needed) shaped my future and the future of my siblings. I now have a daughter, and my wife and I have a number of years to before we worry about equipping her with technology (right now spending time with her and helping her be a happy well adjusted toddler are our primary concerns). In the spirit of my parents choice, what type of tools should parents be equipping their children with, today?"

Why Do Google Hit Numbers Vary? 378

Supa-Fly writes "I have a question about some conflicting results with the search engine google. I did a search for "pictures of mountains" and got exactly 1 million results. My friend did the same search (from the same office)and got 1,010,000 results. A second friend did the same search as the last 2 and got 1,020,000. These have not changed and every person gets the same results each time. My question is what is up with the discrepancies on google's search results?" Since this question is hard to answer from the outside, Craig Silverstein of Google kindly supplies his best answer to this question, below.
