Right. But this requires cooling to liquid helium temperatures. That's a separate level of hard and cost compared to liquid nitrogen.

Why not? Because the single greatest threat to Amazon's business continuity is a major quake in Seattle. Vancouver sits on some of the same tectonic plates. It's likely that this move is, in part, an attempt to address the busines

This is a joke. The latest MacBook Pro redesign is an affront to pro users. At our hardware/software startup the new MacBooks are unusable due to the limitations of the USB-C ports. Our engineers refuse to engage in the dongle shenan

I've created a lot of 3D printed gears over the last few years and one of the best tools I've found is from Rainer Hessmer. http://hessmer.org/gears/InvoluteSpurGearBuilder.html It allows you to specify addit

What you are describing is called "backdriving" the gearbox. Generally speaking, gear trains with high reduction ratios don't like to be backdriven. Small steel gear trains with ratios in the 1000:1 range can destroy themse

This is a pretty shitty apology. The key problem is that ekjp isn't owning the failures directly. Just look at the language in the post... "We screwed up." "We haven’t communicated well..." "we acknowledge th

I know some of the people who have signed up for this and I can say with confidence that I'd happily take them at any salary. The fact that some of the best and brightest in our industry have decided to do this work because it's i

That level of accuracy would be hard to achieve. Most radio signals (eg. BTLE) don't travel well through water (eg. snow). Additionally, if you've ever dug someone out in the field (or practiced doing so) it takes a lot of effort

I'm an engineer so when people ask if something is possible my honest answer has to be that anything is possible. Would you allow me to rephrase your question? I'd rather answer the question, "What is the likelihood that the

I totally understand your concern. That's why we NEVER turn on the stove for you. All modern stoves require you to push the knob in to move it from the off position. The Meld Knob is mechanically incapable of defeating this safety i

I agree that we don't have a controlled study in this case. However, it will be interesting to look at this data at the end of next season. If the Patriots fumble stats revert to pre 2007 levels it will certainly raise some interesti

Analyzing outlying statistics across all the available variables would be an interesting technique to try to predict other potential rules violations. This could apply to many different types of sporting events. I wonder if anyone is worki

I don't think so. I can almost hear Jeff's voice... "Don't make your problem the customer's problem!" There are often many technical solutions to create a particular customer experience. Jeff never accepts fa

Would someone please start a religion that denies the authority of the TSA so we can opt out of this security theater on religious grounds?

Setting aside whether dollar cost averaging into a low cost index mutual fund is a good or bad strategy, the author falls prey to a common investing fallacy. It is most evident in this sentence, "Over the long haul, you won’t lose." Experi

I tend to think we use it quite a lot internally. For instance every amazon.com web server has been running on AWS for quite a while now. You'll find more info here. http://psav.mediasite.com/mediasite/Viewer/?peid=7ab95f6a5d4... We're

I think the most impressive stat is a little later in the presentation. Only ~0.001% of deployments actually cause an outage. Anyone can create a system that generates a lot of deployments, but what really matters is that you can complete
