Surface Pro 3 cursor disappears

I like my new Surface Pro 3. Things were working fine and all of a sudden, the cursor would disappear. I just have the Type Cover and a memory card installed: no other hardware. Narrowing down the issue: if I move my finger in circles on the trackpad to make the cursor move in small…

I spent a few hours at a local company called 2Bot (http://www.2bot.com/) which makes a 3-D printer that you can attach to your computer via USB port. Yep, I said 3 dimensional: you can feed it an architectural drawing of a building or landscape, and it actually can carve it out of a block of…

Are water and salt the only inorganics we consume?

Of all the naturally occurring foods/drinks that humans normally ingest, is it true that all but two of them contain carbon? In any case, these 2 are very common. Maybe there’s a candy bar I don’t know about that doesn’t have carbon<g>. (Of course I mean pure H2O and pure NaCl.).   I suppose that…
