I thought testing against placebo was a standard procedure in medicine and without such testing treatments wouldn't even be approved.


Yes, but patients always consent to be randomized to the possibility of being treated with placebo.


> Yes, but patients always consent to be randomized to the possibility of being treated with placebo.

This is false as a blanket statement. For specific categories like Cancer treatments, nobody is given placebo in Phase III for example, because their life/survival is at stake. For such clinical trials you prove the efficacy by comparing with the typical survival in other studies/other treatments (overall survival chart) like this: https://media.revlimid.com/wp-content/uploads/mm-hcp-overall...


Right, more correctly I should have said:

Yes, but in trial where patients may receive placebo, the patients always consent to be randomized to the possibility of being treated with placebo.


in a clinical trial setting or in general? I'm not sure about everyone else, but I sure wouldn't want the possibility of getting a placebo when I'm at the doctors/hospital.


trial only.

you would have to consent.


jonawesomegreen linked to a story about an FDA-approved fake treatment.


> I don’t think it is an accident that the world’s top female boxer is Norwegian rather than say Italian.

You mean the Colombia born Cecilia Brækhus?

https://en.wikipedia.org/wiki/Cecilia_Br%C3%A6khus


Which is irrelevant given that she was adopted and raised in Norway. Anyway she is just one example of Norwegian women punching above their weight. For a number of years Norwegian women were the best soccer players in the world. There are many other sports examples.



I would interpret it as "fallen horizontally" with a lot of braking happening lately in the atmosphere.


Slightly offtopic, but most easiest way for detecting tampering with hardware is weighing stuff.



I see comments like that every once in a while, and I always come back to something that one of my professors told me a long time ago. If it took you like five minutes of thinking about it to come up with it, it's a safe bet that a) folks who are paid to work on this stuff full-time have already thought about it and b) that someone already figured out how to work around it.


That's great if you're looking for whole extra boards in a device with grams or tens of grams of additional mass.

These surface mount components are so small that the variation in the volume of solder on the joints alone would render your technique moot.

Add to that, the fact that manufacturers often use multiple suppliers for parts, they could have different materials, densities and casing designs, this particular problem is beyond weighing.


Reminded me of this tweet I found earlier today: https://twitter.com/arbedout/status/1047822585009004545 They actually shifted from weighing stuff to measuring angular momentum!


this "tweet" is an embedded screen capture from HN :)


Couldn't you measure star motion over longer periods of time, then even minuscule amounts of motion could be detected.


By the time you can see the motion on your image sensors it's too late - you want to detect and correct the motion you need to do it while you're imaging stuff, before it smears all your measurements.


I have started to view "baseload" generation more in a negative sense (as in "can't be easily turned on/off").

Also the daytime/nighttime power consumption differs almost twice, so almost any solar added only smoothens out the difference.

Also the new offshore wind turbines (>10MW) offer some extraordinary capacity factors (~60%). Makes me wonder what these capacity factors could be if we could get to 20MW turbines.


Traditional "baseload" plants are a product of cost and engineering. Nuclear and baseload coal plants are designed to deliver maximum power for minimum cost. Due to engineering constraints, this means that it's hard to scale the output up or down to meet changes in demand (hours? days?). So short-term demand is dealt with by "peaker" plants, which are very expensive. They're less efficient, and they aren't always in use, which means tying up capital in something you don't always need.

I think of solar/wind as a sort of weird baseload, with a wide variance in output that is not controllable and not always predictable in the short term.

Where I think we have a real opportunity is the application of modern software to this unpredictable power grid, by pricing power dynamically at a rate that matches the fluctuations in both supply and demand. At this point, building storage to stabilize the grid is arbitrage, a market imperative. Independent storage systems can buy power from the grid when it's cheap (sunny, windy days), and sell it when it's expensive (cloudy days with no wind and high demand). Then it's just a numbers game, and the market itself will provide the right amount of storage.

This gets more fun as electric cars become more and more common. Every electric car is just a big battery, right? Plug it into this smart grid, and you can make a few bucks using the same arbitrage as big power companies. Sell the power in your car!


Mosquito net is the first thing that comes to mind.

Then EM pulse weapons, lasers etc.


> Mosquito net

That's addressed in the film.

> EM pulse weapons

That's not actually a thing.

> lasers

Aside from being impractical, this is bringing a knife to a carpet bombing. The video is about the potential of autonomous drones being used against civilian targets. Unless you put all civilians in bunkers guarded with lazors, they are irrelevant (plus of course you still have created a nightmare scenario where humans need to live in bunkers to avoid random electronic micro-terrorists).


How much energy is actually transferred from car to cyclist?

Records with too strong assisting wind often are not recognized. [1]

[1] https://en.wikipedia.org/wiki/Wind_assistance


This record is fastest speed on a bicycle while drafting. I don't think wind assistance matters.


I suspect publicity created by this will easy recoup all expenses.


How?
