Sigh. Thank you mods for removing the only reason this page is currently relevant. Original title was "The rocket that would have gotten us to Mars in 1978". Which is completely truthful, uneditorialized and why folks might be interested

So it is 21st century digital microfiche? Clever. I do know museums will probably line up for this stuff - standard CD-ROMs start to rot after 10 years and DVDs are better but relatively untested. I wonder how much FEC is built into them.

I had the same thought several years ago. To that end I made a CMS designed to make writing this sort of post easy[1]. It never got out of closed beta because I just could not find people interested in doing and documenting projects.

I do not believe you have actually read any of the conversation. Still waiting for someone to show me a state machine that absolutely needs goto.

by keenerd 14y ago
I would not really call that a state machine. (Or a parser.) Which were the topic at hand. All of my state machine have been for embedded targets and generally look like rules(struct stateful state) { switch (state->foo

> Do you write parsers or state machines very often? Yes and yes. Never have used or needed a `goto` in C for these. Could you provide an example of how it would be useful?

This is largely a response to the very disappointing attitudes found in a recent thread [1]. I doubt this writing will be very convincing or change anyone's mind. Particularly here, as there are a lot of people who really believe in t

No, I think they will replace the aluminum case and the battery as a single unit.

While I never said it was not legal (though I may have implied as such considering seat belt laws), code does require properly grounded outlets in bathrooms and other high risk areas.

Do you absolutely 100% trust the GFCI breaker? They do require a small imbalance to trip, so something bad could happen in that brief time. Or maybe stopped working one day. But technically yes, ungrounded GFCI will still protect you. Do

Hey, you were the one who said molten :-) I guess you meant something more like blacksmithing. Chamber could add heat by microwave induction. No air to oxidize the surface so you might be able to work trickier metals. We already have pow

by keenerd 14y ago
Do you mean having a blob of molten metal floating in a chamber? Surface tension means it won't keep a shape. (I guess you could make cheap ball bearings.) If you get around that, any time you touch the blob it would start rippling and r

Everyone forgets about 3D printing's older brother, 3D milling. Start with a big block of aluminum (or any metal softer than the cutting bit), use what amounts to a CNC dremel tool to carve away everything you don't want. It is vastly sim

I would not say better - different certainly. Jsonpipe is a lot slower and heavier. (Matters when you are adding json based web 2.0 integration to your router. For small cases jshon is 15x faster and uses 1/14th the ram.) And I would re

I really want to believe this is real. The cynic in me says that anything this outlandish is a fraud - something akin to Project Azorian and magnanese nodules[1]. The parallels are uncanny, but even as a cover mining asteroids makes no se

Site does not render without JS enabled. At all. You get a flat white page. Enabling JS lets it render, but also scrolls crippling slowly. If I could downvote right now I would. But it gets worse. Nothing in here is about graph theory.
