I had an an interesting moment recently where I watched my 88 year old grandfather seemlessly set up music from his Alexa, and order something on Amazon. We might just not be the target market.

Detecting one pulse above background noise is not terrible, according to the paper. However, the way the paper sets up their communications channel is kind of silly, since they are pulse rate limited. If you wanted to transmit a lot of info

One bit is sufficient if you are just trying to arbitrage markets. For a couple billion, an NYC to Tokyo neutrino shortcut wouldn't be a bad investment.

No offense, but defense spending is exactly the same as what you describe. It's money that goes to hundreds of thousands of workers that spend it in the economy. Unlike (some) defense spending, UBI doesn't intrinsically create som

Commenting on the research design. This research, to me, seems to be ignoring the biggest open question of UBI. All tests to date have looked pretty good, but have only been done on a micro level. The fundamental issue one really needs to a

There is a big difference between loaning $1T once, and getting paid back, versus giving it away every year.

There is an interesting phenomenon of exclusivity/sunk-cost boosting ratings for rarer or harder to acquire items. That is also a problem with movie ratings (I just noticed that you mentioned movies). Critics (and audiences) at pre-scr

That's more small business category. With a business plan and stable income, getting a small business loan isn't hard. In this case, there is an asset value risk, but that doesn't mean this is large company territory...

I'm curious if inspections were even a thing back then... This predates the era of locking your employees in during their shift.

Sort of Without HVDC, renewables will probably peak lower (15%) than the 35% I mentioned. HVDC and UHVDC is getting fairly cost effective now, so I don't think we'll need huge government subsidies to see adoption there, and it can

I agree that we'll likely have a mix, but the point I was trying to make was: Before, we had low variability in demand, so things like nuclear, hydro, and geothermal ("clean" methods of producing base load power) had a chance

There are a couple of things everyone should know when it comes to energy production: 1) Energy investment is primarily driven by cost, not perceived/actual safety. Safety regulations do affect cost, but not enough to significantly cha

I think you're being slightly unfair here in assigning credit/blame/what-have-you. I agree with you that she liked it, and signed off on the product. However, we had to scale the infrastructure 7x. That wasn't a VP level

I agree that she supported the launch, but Marissa wasn't involved in any of the infrastructure work, machine planning, etc.

Hm, let's not have personal attacks here, especially for a topic on which you do not have any personal experience. Having worked on Google Search during this period, I can say definitively that your comment is mostly incorrect. Feature

Average capacity factor for solar cell is about 25% (night, clouds, seasons, etc). 1000W/m2 * 0.25 => ~250W/m2.

Usually the better pitches have a discussion on risks/challenges to overcome, and how you are going to use the current VC round to do that (and the timeline, etc). "Big risk item is delivering T tech by D date, requires P person f

That is not quite what that means. Usually that means "We kind of like your idea/team, but we don't have the technical resources to fully diligence it (or manage the board after funding), so we want to wait until someone more

From the VC side, it looks like this: "LOOK AT ME LOOK AT ME LOOK AT ME! Ok, what do you have? 40 slides that tell me nothing other than you have a big vision and if you own 10% of <insert market here> it will be worth a lot.&quo

Well, a little micro mechanical device offsetting the internal balance could work, though the balance change would have to be pretty large to bump the probability of any one face up significantly.

For those curious, this article somewhat oversimplifies the situation. Coal is dying anyway. "Clean coal" generally refers to coal => gasification => carbon capture. This is possible, just more expensive than burning raw coa

How was your experience in the study? Do you feel like the UW study missed any important questions or aspects of your life that would potentially alter their conclusions? As for depression, from what I can tell of skimming the UW paper (hop

I realize that UBI is a very popular position on HN, so I am hoping someone here has given this more thought and can comment. My problem with UBI is that all tests to date look great, but have only been done on a micro level. The fundamenta

If I am reading this correctly, there were 6,158 patents with ~200 true positives, so approximately 3% of the population. 98.04% sensitivity (recall) and 90.2% specificity (%true negatives) leads to... ~4 false positives for each true posit

Yes, you have a point, though the reality is even more complicated. There are physical limits to the heat capacity of the rock, and the heat flux into the region. Deeper wells are not necessarily hotter. Going hotter adds other costs (drill
