It's only better if they move elsewhere and refuse to vote for the same policies that caused the problems in the first place.

...sure, but there are superconductors at a lot warmer temperatures than 77K.

You might be interested in the text of the fourth amendment to the U.S. Constitution:

...and the 9th:

"The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people."

xrange··on What is Symbolic Computation?
Common Lisp declarations are hints to the compiler that is doesn't have to do as much type checking, and so it can speed things up by omitting type checks, because you the user told the compiler it was safe to do so.

...SBCL with certain level of safety declarations does mostly do what you really want though.

xrange··on Moving Forward on Basic Income
>As such, it's likely that this study will find, entirely correctly, that recipients are happier, more productive, etc.

I wonder what the right way is to measure happiness for a group. Say this test makes 20% of participants much happier, 70% about the same, and 10% overdose on heroine? And what metric can you use to quantify happiness on an individual level?

>If the pilot goes well, we plan to follow up with the main study. If the pilot doesn’t go well, we’ll consider different approaches.

I'm excited that someone is taking the initiative to test the idea further. Any thoughts on how to tell if things "go well"? Is there a set of metrics that will published beforehand? Most of the claims I've heard about basic income tends to fall into the not-falsifiable camp. I am very interested to see what data/results would convince a basic-income proponent that it isn't a good idea. (I think the opposite would be easier, turning a basic-income skeptic into an advocate).

>Or 1000 years from now terrorists dirty-bomb everyone.

...Well, on a more optimistic note, a dirty-bombs, while they may destroy property values and cause cleanup issues, don't really kill any more than a conventional/kinetic bomb. I think they may be one of the best-case scenarios when it comes to a terrorist strike, since the causalities will be low, but there will be a lot of "frenzy" about the invisible radiation. (I'm sure someone will correct me if I'm wrong, or if there are silent aerosolized short-half-life "bombs" in existence that are "detonated" secretly inside of buildings so that people are accumulating long term exposures unknowingly).

Also, I wouldn't be surprised if room-ish temperature superconductors appear much sooner than 1,000 years from now. And it will definitively be interesting to see how high of energy densities SMES (Superconducting Magnetic Energy Storage) will get to in the next 20 years with existing cryogenic superconductors.

>After 6 years I will be earning $4-5k/year from it.

Can you point us in the direction of a good write-up on net-metering? I'm sure different jurisdictions have different rules. I was under the impression that net metering was only good up until your yearly production was equal to your demand. Or are you saying that the $4-5k/year is at wholesale rates?

xrange··on Remote code execution vulnerability in ImageMagick
>I agree to the extent that "Rust will save us" is a glib answer, but dismissing it completely is equally silly – safe-by-default is an excellent tool to help prevent many of the common sort of vulnerabilities we see in C code.

There have been all sorts of safe languages that are appropriate for image processing and other types of programs, but people apparently like programming in C more than they like secure software. It is hard to see how something like Common-Lisp/Ocaml/Haskell/Java/Eiffel/C#/Ada wouldn't be more than up to the task, with only a slight speed penalty. It seems more like a social issue than a technical one. Maybe Rust will finally be able to break through, but I wouldn't hold your breath.

>I don't think you can do small scale experiments

What if you started everyone out at $50/month, and increased it slowly over the course of say 10 years or 20 years, or 100 years to whatever target you liked? Or do you think a gradual introduction would invalidate the results, or that you couldn't extrapolate from people's behavior at $300/mo, what they might do when the payout is $1000/mo?

Or what if you started walking the social security age backwards gradually, making people eligible at the age of 60 in the year 2020, and 55 in 2025, and 50 in 2030, etc.?

Can anyone shed insight on Indian reservations and basic income. For some reason I thought that some reservations with casinos had payments to all the tribe members?

>You don't get much useful information about people's willingness to continue working when you target it at people who have retired.

What about the other claims that some people make with BI, like an explosion of new exciting art/music/novels, etc.. Is that testable with SS recipients (say looking at how many novels they write the year before, and the year after they retire, counting the number of hours they watch TV before and after retirement). Or are they an invalid group because they are old? Or are the "other" category of BI claims mostly just feel good claims that no one really believes?

xrange··on Powerful Political Forces Are Aligning Behind Minimum Income
Here's something I like to see some discussion on from Basic Income proponents. Does BI need to be rolled out everywhere-all-at-once, or is it possible to do small scale experiments to look at the effects? If you think it is possible to have meaningful smaller scale tests, how small can it be? 1000 participants? 100,000 participants? 10,000,000 participants? And then the big question, would there be any outcomes from these smaller scale tests that would convince you that BI isn't feasible? Can share your list of those undesirable outcomes that would change your mind about the desirability of BI? (No sense in running tests if no one will change their mind). Also, what do people think of the Social Security retirement situation as being a fairly large example of BI, that has been running for the last 80 years on a subset of Americans. Does the fact that they are older invalidate it as an example case in your mind?
