Comment The Cray-1... (Score 1) 105

The Cray-1 was ECL. The Altair 8800 was TTL. We're now CMOS, but I wouldn't mind an ECL i7, despite the fluorinert waterfall... (My real point is that there were very serious differences between the Altair 8800 and the Cray-1 despite the obvious which lend to significant differences in power dissipation...and speed.)

Additionally, the other thing this article doesn't take into account is the preponderance of battery-powered modern devices -- before, power consumption wasn't really much of any consideration (plus, now it's marketing!)

Doubtful. Highly doubtful. 3d printers are faster than their traditional manufacturing coutnerparts in some applications, but they don't allow you to manufacture anything you couldn't before. Other than that, the idea (while fittingly /. tinfoil-hatty) seems absurd.

So you install a constant-velocity motor generator set and...

well, if you were a military installation protecting something important, then it'd be a bit different. Yes, it's very wrong to sell it to a commercial entity, but it's not wrong at all to collect it. You're buying power from these people -- it would be like asking your water company to stop using their AMR equipment. Or gas -- oh no, they know when my water heater cycles and I use the stove. It's strange, I feel that people are diverging on privacy. On the one hand, they don't care about privacy of their personal lives and relationships (re: Facebook) but now they care that someone knows how much electricity they're using? Enlighten me if you disagree with my opinion that this is all a bit silly (remembering that I am not saying that commercial sale of this data is OK)

Comment Thou! (Score 1) 2288

As an electrical engineer, I would point out something rather funny: even European electronics (in majority) are still specified in thousandths of an inch as the primary dimensioning measure, as almost all surfacemount (and PTH) footprints are still in thousandths of an inch. Is this what we get for inventing it?

Comment Re:"Alternative Narratives"? (Score 1) 642

The Constitution is an ancient and generally deprecated document in light of far more informed and recent documents as the constitutions of Europe. We would be in a similar situation if we looked upon the Framers as fallible men as ourselves and it as a fallible (and correctable) living document. If the Constitution was properly cared for over its lifetime, we could be moving forward, not backward.
I am saddened by your confusion of opinion with fact. Look at statistics and you will discover that your statements are antidemocratic -- and arguably anti-American. It would be easy to say that I'm 'just reading the statistics to support me', but that false counterargument has gotten really old.
Judicial review isn't constitutional. Are you questioning it? In fact, much of the Supreme Court itself is extraconstitutional, and the Senate so skews representation per populace in this country that little (red, uninfluential, &tc) states can influence the ways of the country disproportionately. States do not deserve representation -- they are geopolitical units. People do.
And yet, where are women in our government, for example? And besides, I can't see why so few can learn addition -- cutting taxes gets us nowhere, almost as nowhere as attrition measures. Raise taxes already! Reduce rampant income inequality in this country and we might get somewhere.

Also: don't argue for States Rights. I don't need to tell you why.

tl;dr: Read the Constitution.
Learn more about the constitution.
Come up with your own words.

Submission + - Open Spark Project: Your Music. Played Through Li (opensparkproject.com)

An anonymous reader writes: The doors are open on the Open Spark Project, a rare opportunity for musicians around the world to see their music turned into lightning. Cleveland-based performance engineering group, the Tesla Orchestra, launched the Open Spark Project last week, to let people around the world in on the fun of playing with giant musical bolts of electricity. Already Girl Talk (pop mashup star) and others have signed up to enter songs into the project. Thanks goes to Paul Buchheit (Google Employee #23 and inventor of GMail) for sponsoring all this excitement!

Entries accepted until May 2nd, and then on May 14th the musicians and fans around the world can watch a live video feed at opensparkproject.com as we play selections from the entries on our two giant musical tesla coils. Musicians, come see your music turned into lightning!

Scientists and Engineers might wonder how the music is made. A traditional (non musical) tesla coil involves a series of resonating circuits, building up voltage higher and higher until it discharges through a spark. Part of that circuit is an air-gap switch that lets the first resonant circuit build up a high voltage before transmitting the energy to the second resonant circuit.

Now, replace that air-gap with a set of giant transistors, capable of sustaining thousands of amps of peak current, and you can now control when that spark can fly. Our musical tesla coils resonate around 30khz, discharging sparks that are several meters long. Using the transistors (called IGBTs) to turn that spark on and off at say, 440hz, will result in a 440hz tone, or A4 on your standard piano keyboard. The same holds true for other frequencies, and so the tesla coils can reproduce any note on the piano.

Any noise that you can turn on and off can make music this way, and the DIY Maker community is full of musical projects that use printers, hard disk motors, you name it, all in the name of music. We happen to like making music with giant bolts of lightning, and we hope you'll enjoy it too.

The equipment cost is on-par with most computers Slashdotters probably use, and the cost of the exam is trivial ($14). The exams aren't particularly difficult, either, and most people teach themselves. Not trying to be snide, but I would like to point out that it's not really all that difficult to get into.
