For me it depends; if there aren't any comments to the article/discussion, then I'll click the article if it sounds interesting. This is almost always the case, too, if I am browsing "new". Otherwise I'll click

It used to mean something better than that - a "grinder" was someone in old-school parlance a "wirehead". That is, they were someone who uses or tries to use technical and/or electronic means to "hack" the

My senior year physics teacher in high school was a PhD student at Princeton who was doing teaching waiting to get back to his doctoral thesis research. Apparently, his work was with the Plasma Lab, primarily the Tokamak they had. Someone a

Probably the idea was to keep the current from crossing the heart/chest area, the right side being further away (to some extent in most people). There's a similar rule for HV work (and when working with vacuum tube-based equipment

I had basically the same thing happen to me several years ago, but on hamburger; $1.49/lb for 5 lb? Nope - $1.49 each! After a cartload at one store; went to another - same. It was system-wide. So I went to a couple more over the next

If I were doing this, there'd be a number of questions to ask yourself before you dumped a lot of money into it: 1. Is there a version of Windows for the RasPi (I think this is true, but it's been a while)? 2. Will Swarm and any o

What I've noticed about all of these thermally based systems - this one, the earlier (and DIY capable) one made of fishing line, and heck, even shape memory alloys - they all seem to have relatively slow cycling rates for either the en

So you're saying I could walk into Bank of America, say I wanted the current 50 pound British note in proof condition, pay the current exchange rate ($63.00 USD currently), and walk out with one that same day? Doesn't seem possibl

As an alternative, what if you didn't have (or didn't want to use) common structured programming techniques, and you wanted to implement a state machine? Like, you could use if-then, but not while, loop, do, etc? But goto was allo

ASU and Mesa Community College both use solar panel installs as covered parking areas; Fry's Marketplace over at Bell and I-17 has their parking lot under a solar panel shade structure, too. So the idea is already there and makes sense
