They start out nice and shiny, but get gummed up rather quickly.
Then you're doing it wrong. Switch to a hotter heat range. Use platinum or iridium plugs. Make sure your coil is putting out the prescribed voltage. Tune your mixture so it's not too rich. Then, assuming you're not burning oil, at 35,000 miles the plugs should still look clean.
Have you considered making it light enough that your arm doesn't ache after 5 minutes?
Dude, you need to push away from your computer, climb out of your mother's basement, and get some exercise. Yeah, I know the Sun is bright. It won't kill you. (Well, it might, one day, but that's a subject for another discussion).
Well, at least the Seagate drive had the common decency to make the click-of-death noise, to let you know it failed. Imagine if they simply stopped working! Where would you be then?
Yes, Ball Grid Array. (sorry for the late response). I know they're used industry wide now; so, you'd think that it would be a "mature" technology. Despite this, I recall that when we moved to using BGA components it was a multi-month learning curve requiring numerous board revs to get the recipe right. Despite this we still have intermittent yield problems and when a board fails in the field, more often than not (assuming the customer hasn't opened the instrument) it's the BGA soldering.
It's not so much the move from tin-lead as it is the move to BGA technologies. BGA's have become very common and are a nightmare to solder. If they aren't done right you can have all kinds of thermal issues pop up later, after the boards are out in consumer's hands. The boards can be repaired but I'm not a real big fan of reflow.
no no no... The microscopic black holes made by the LHC are going to be used to power the new battle platforms DARPA is preparing to launch into space.
except that something like 1/5 of the population dies of cancer anyway. So, getting 100mSv increases your chance from 200/1000 to 205/1000 (based on increase in risk.05%/rem, which is debatable). However, most studies show the increase in cancer rates cannot be distinguished from background until dose exceeds somewhere between 10 and 20 rem (100 - 200 mSv).
There's nothing wrong with Windows in the lab. You don't have to use LabVIEW. You can use any dev system you want, any language you prefer. Write FORTRAN code and compile it with the command line tools if that's what you like.
Part of that's because of the PR nightmare the discussion always becomes and management's desire to avoid that at all cost. Unfortunate. If you open a news conference with "There was a release of radioactive steam..." it is nearly impossible to get across the point that the effective dose for someone within one mile will be equivalent to eating one or two bananas.
There's a similar lack of information on the oil refineries that burned. How many people died in the fire? How much land was contaminated by the byproducts of the uncontrolled chemical burn raining down? How long will it take for the benzene, toluene, naptha and other organic compounds to decompose in the surrounding farmland?
And the nuclear plants will be fine. If you check, there were 4 power plants, each with multiple reactors, near the site of the Japanese 9.0 quake. All of those reactors shut down normally and survived the earthquake.
Only one of those sites is having any trouble -- and it is only because an 8m tall wall of water topped their tsunami protection wall (it was designed to stop a 6m tsunami). The water knocked out their connection to the power grid, flooded their backup generators AND the backup backup generators. It also damaged many of the electrically driven pumps. Fukushima Dai-ichi is a rare case where, due to an essentially unforeseeable event, a single cause destroyed the primary power connection, primary cooling pumps and all of the backup systems simultaneously.
You can be sure that once the situation in northern Japan is stabilized, changes will be made. Now that they know an 8m tsunami is possible they will upgrade all of the tsunami barriers over the next decade or two.
until you factor in the earthquake and tsunami.
water + sodium = BIG BOOM.
You fail sir. The 4S reactor is placed 30m underground in a concrete and steel containment vessel. The sodium is encased inside the reactor and cannot come into contact with anything outside the vessel. It's a sealed unit. There is a transfer loop that you pump water in and get steam out. The earthquake would shake it. The tsunami would damage the above ground equipment. And the reactor would be fine, sitting in its containment. I believe (and I'd have to go look to be sure) the Toshiba 4S uses a neutron reflector ring that's coupled with fusible links to the control rods. If it overheats the links melt, the reflector drops to the bottom of the vessel, and the reaction stops. Of course, now you're sitting on a dead reactor that you'd have to send back to Toshiba for refurbishment. Yes, the thing is designed (in principle) to be recycled and refueled at a Toshiba factory.
Are you trying to say you DON"T have a thermite charge around the hard drives in your computer that is activated by a one handed keystroke? I thought it was obligatory that every hacker put those in...
What's wrong with coding drunk or coding standing up. Works for me. obligatory XCKD reference (Although, my experience is that the Balmer Peak happens a bit earlier than 0.129BAC0.138) NOW, as for the 3D modeling crap, that was over the top. I do all my graphically modeled coding in 2D, in LabView.

That's fine. It'll also work on syn-gas and alcohol fuels.

Yep. Just pump in NOx or LOx, add spark, and you're off.
They learned this from BSD, which is a grandparent of OS X

polycarbonates make wonderful fuels. They can be used in solid rocket motors, if mixed with a suitable oxidizer.

Except that the machining process for the unibody chassis is very energy intensive (expensive), as opposed to a casting or molded plastic part.
no no no... The microscopic black holes made by the LHC are going to be used to power the new battle platforms DARPA is preparing to launch into space.
The formation is hot enough that you could use a closed loop, cycling pressurized water in through loop of pipe acting as a heat exchanger.
I'm sorry, but I'm afraid I need a car analogy..
a millimeter is the same as a 0.040" spark plug gap.

People in the industry know the difference between Nat. Semi., TI and NI. You must be referring to non-techies.
They're using red, near-ir, and ir wavelengths to create a false color blue, green, red visible image.

I give, if they can't sell it, just how much money are they trying to sell it for?
it's a huge tract of land. The accelerator was 20 miles in diameter.
I'm separated from the nearest window by a concrete load bearing wall and an additional 20' of office cubical space.
