Comment Re:Joyent unfit to lead them? (Score 1) 254

People like you can't tell a noisy obnoxious scammer apart from a person who actually contributes to the good of humanity, and your respect is more often than not woefully misplaced.

As result, nobody of any actual significance cares about your respect - only your companions from your echo chamber, blinded to any real world issues, do.

Such minimal corrections are a clutter that makes actual, important changes get lost in the noise. It's not that the change was wrong. It was that the usefulness of the change didn't justify creating the clutter it added on maintenance level.

Is this comment sexist?

Is this something worthy of firing a talented expert (as the company blog suggests) over the above?

Do you have your priorities shoved so deep up your ass you really believe using correct gender pronouns in comments of your software is more important than having the code written well?

Your philosophy is to waste time, effort and resources for an army of experts and spit on their work, so that in the extremely unlikely case someone who is bothered by gendered pronouns happens to read the obscure comment at obscure comment of an obscure part of some code?

By the way, show your face, don't post as AC.

Comment Re:Efficiency??? (Score 1) 103

The point of transmission is not only "displacement" of rotary movement but also exchange of rotation speed for momentum. So, if (as the article says) the gear ratio is 1:20, it means the load on an axis two such transmissions away will be 400 times that of a motor.

And while, yes, the design makes the system safe against damage due to too high load, the load it can provide is still far away from load which could damage the mechanics; if the slippage was to occur at loads ten times as high, it would still be outside the self-damage zone.

Way more efficient than gears for loads it's designed to handle - but it's not meant for heavy lifting; the "magnetic gears" will "slip" if the load is too high, and in this case "too high" is quite low (think force required to move two magnets oriented in "repulsing" way against each other).

It would be great for stuff like stabilizing flywheels - things that once set in motion stay in motion for years, and may take a long time to spin up or stop. It would work well for things that require very little force, like reorienting the solar panels or aiming the antenna.

OTOH, stuff like lander wheel bearings or drills for picking samples are better handled with normal bearings that can take much heavier loads.

It's not a cure-all solution, it's just a good new option for specific applications. You won't use it to build a better crane but gyroscope flywheels could immensely benefit from that!

Comment The area IS dangerous. (Score 2) 409

The area is dangerous. The radiation is about the least of the concerns.

First is the abundant wildlife, with rabies affecting a large part of the population. Wolves, foxes, wild boars, cats, stray dogs, lots of rodents. It's a very serious problem and it will be difficult to contain.
Next, the old infrastructure, in major part stripped of metal parts. Open manholes hidden by vegetation, barbed wire fences hidden under layer of weeds, buildings that stood with missing windows without renovation for nearly three decades, about to crumble.
Chemical contamination - abandoned communal farms where pesticides were left in rusting containers. Laboratories in hospitals and institutions, assorted abandoned factories.
Huge forested areas with big risk of fire.
Unmaintained drainage/sewer systems causing risk of flood.

Radiation is not entirely non-issue either. Yes, the land is mostly fine. There are few open areas where restrictions are still important(like that concrete-covered peninsula, where the levels under the crumbling layer of concrete are still dangerous), but you could safely farm most of the land that was farmland before the disaster. There are also "pockets" of radiation in places where trash from the power plant area was dumped. Old rotten clothes in the basement of the hospital clock good 2mSv/s. Soil of the Kopachi area will produce plants actively harmful to health. Supposedly the bottom of the Pripyat lake is badly contaminated; if water levels fell, wind would carry contaminated dust.

It's a place where responsible adults could live. It's not a place where you could let kids loose though.

With water cooling, you can pull the pipes as far away as you like. Even outside the house. No latency issues like with cables.
That makes for some very quiet systems (except for where the pump is - basement? attic?).

Of course the moment your system is silent enough she'll find a different reason to complain, or act all passive-aggressive. I highly doubt it's the noise that annoys her.

Comment Re:We may hear from Philae later (Score 1) 337

Yes, the comet's perihelion is about 1.3AU so not much farther than Earth's orbit (and so Earth surface heat input), and yes, ice melting temperature drops significantly with pressure. As for what forms the emission takes, this is one of the huge questions Rosetta is suppoed to answer - we've never observed a comet from near enough to see how exactly the melting process works. In one hand, the chance that they will be explosive is quite low (though non-zero, under-rock ice pockets heating up and accumulated steam blasting its way out), on the other hand Philae weighs about 1 gram while on Chury, and its size is around 1 cubic meter. That's about the parameters of 1m^3 sized soap bubble when it comes to reacting to "wind". So the emission doesn't have to be anywhere near to explosive; even mild zephyr from under the surface can move the lander.

Since we still don't know about the character of the emissions from the comet, we can only guess whether the point when Philae heats up enough to starts charging its batteries happens before or after the comet produces enough steam to blow it away.

Of course, had the harpoons deployed, that would be moot. Currently the outlook isn't too good. Philae is in a hole, which can channel the steam into a stream. Plus its systems could have been damaged by extreme cold, plus even the intensified sun input may be insufficient, plus the 'seasonal shift' of shadows can (though is unlikely) to worsen the shadow conditions... Still - until the comet actually begins emitting steam and we see how it does it, we have really no clue what's going to happen.
