Comment Re:This is good news. (Score 1) 189

My company makes a good bit of money off something that was once patented. The patent is now expired, and we are allowed to make it. I don't know the whole history of it, but the only reason we don't patent our product is because it already had a patent, and it's now expired (and, of course, we didn't invent the basic technology but more of a method of producing them). I would bet there are *tons* of products that are sold now that used to be covered by patents.

I can instantly light a log on fire with my ~2.5 x 3 ft Fresnel lense, and melt a penny within maybe 30 seconds to a minute. The delay is mostly from the fact that it's a big floppy piece of plastic that's hard to hold straight enough to focus. I bet you could melt some bronze or aluminum pretty easily with this!

If you mean the e-fuse, there was a lot of talk about how it "bricked your phone" if you loaded an unauthorized OS on there. What it REALLY did was that it kept the phone in a constant boot-check-reboot until an authorized OS was on there, at which point it worked just like normal. Not like the story above, which is discussing theft of phones, not jailbreaking them. (Then again you may be talking about something other than the e-fuse, in which case this post is totally irrelevant lol)

I wholeheartedly agree with this. While the education can certainly be better (not that it always is), most, but not all, of the homeschooled people I meet are just... off. Not all of them, for sure, but most. It seems to me that people have both a level of self confidence and a level of inhibition. Social experiences let you level those out- you need a healthy amount of both to survive. It seems to me that for a lot of homeschooled kids, they have a normal level of self confidence but none of the inhibition that comes from seeing how other people react to you- when you don't have a healthy peer group, it's hard to learn how to act normal.

Virtually any time this is presented in a math book it's prefaced by "Figure out what goes in the parentheses to make this work". This is middle school math here- basically easing them into variables without having to explain how a letter can be ANY number. The summary just didn't include that instruction above since most people have seen that type of problem in middle school math texts. I say most because it was obviously confusing to some. The kids who were trying to solve this problem didn't get the whole "left side is the same as right side" thing, and instead (I assume) thought the equal sign meant "figure out what's on the left and write it to the right."
