Does the OP of this question need to be suspended under the Content Policy?

We don't allow explicit content here.

user315433

I think this falls under a form of use/mention distinction.

user315433

Since the question is asking whether a certain kind of image is explicit content.

user315433

But now that you brought up that policy...

Did you know:
> To say extinction is certain would be a misrepresentation. But risk of extinction has significance different from any other risk: extinction would defeat all human purpose for all time. Although the risk of extinction may be fractional, the stake is infinite, and a fraction of infinity is still infinity. Therefore, the possibility of extinction and the certainty of it are morally the same.

I love this piece of text. Schell 82.

user315433

00:57

@bjb568 Meh. "Action A carries a nonzero risk of extinction". "Yeah, so does not doing A; so does everything. Infinities all around; try a more actionable approach to valuing outcomes"

bjb568

In making a decision, if the risks associated with different choices are different, choose the lower risk. If they have the same risk of extinction, Schell doesn't apply. There is no paralysis.

user315433

But 0.01*infinity = 0.1*infinity, and so on

bjb568

Right, but infinities are different sizes.

user315433

No. The paragraph is exactly arguing that it doesn't really matter how small the risk is.

bjb568

Morally, it doesn't matter, since any threat of extinction compels us to act as much as we can, but in decision making, the different infinities do matter.

user202362

01:01

but it does, according to limit theory - the integral of something during infinite time might be smaller than 1

user202362

really depends on the function

user202362

for example f(n) = 1/t^2

bjb568

Hey, I use this in debate, not math competitions.

user315433

Appealing to the mathematical concept of infinity and then rejecting the conclusion that said concept entails (0.1*infinity = 0.01*infinity) doesn't look like a good move for a debate.

bjb568

I personally don't buy that humans have infinite value. Rarely, some debaters say humans have negative value and extinction is good.

@zaq I can just throw hyperreal numbers at them.

user202362

01:05

convergent or divergent integral is a very basic concept

user315433

My take is that extinction is inevitable: the laws of physics are stacked against life long-term. There is no safe option.

user202362

01:18

do you know that productivity in agriculture and manufacturing has increase tenfolds in the past 200-300 years?

user202362

but if humans are dumb enough to add all those useless jobs and call it innovation, endlessly adding to earth population without putting serious effort into devising a way of escaping in earth inevitable demise, then extinction is relatively near

user202362

humans are fairly retarded as a whole

@zaq Of course, but who knows what this Law of Large Numbers thing is, anyway?

@rene, or somebody, git question

let's say i modify a file, then git commit, but i don't do a git push yet.

then, let's say i modify that file again and screw it up

if i git reset will it restore to the repo version, or to the last committed version even though i haven't pushed it yet? (the latter is what i want)

user315433

git reset shouldn't have anything to do with remote. So I'm guessing the correct answer is (B)

user315433

Disclaimer: I've no idea about git

Q: How do I revert all local changes in Git managed project to previous state?

I have a project in which I ran git init. After several commits, I did git status which told me everything was up to date and there were no local changes. Then I made several consecutive changes and realized I wanted to throw everything away and get back to my original state. Will this command ...

Note the bit in bold on the accepted answer.

Jason C

darn.

oh maybe i could push it, then reset.

Shog9

or just use the first command.

git checkout . should do exactly what you want.

alternately, specify a file to revert only that file to what you last committed

Jason C

i'll trust you. "revert changes made to your working copy" means something to my svn mind that it probably doesn't mean in git world.

Shog9

01:46

should mean the same thing

Jason C

svn doesn't separate commit and push

Shog9

The difference is that commit without push in git actually means something

Jason C

ok here goes nothin...

Shog9

when I used svn, I had to maintain my own local repository, commit to that, and then jump through lots of hoops to push those to a remote repository. Git just does that by default.

With the added bonus of having tons of extra commands and switches for things that I would never do unless I completely lost my sanity, with no obvious indication of which ones those are.

Jason C

great success.

thanks!

@Shog9 i'm still trying to get used to it. i keep doing git commits from multiple machines on the same repo and forgetting to push. then other weird things happen. then i end up with all these weird "merging into master" commits that don't have any real changes attached to them. but for the most part it's been treating me well.

Shog9

01:55

@JasonC yeah... For me, it's awful hard to shake the "don't use source control until you create a repository on a server" mindset. But it's worth it.

user202362

svn? newblet :p ... remember the old cvs

Shog9

I do, although used it only a few times.

Professionally, was on Source Safe for a long, long time. That was hell.

Jason C

i'm pretty familiar with cvs although i haven't used it in a while.

i remember when switching from cvs to svn it was really hard to get used to branches and tags being completely separate paths.

i also remember being annoyed that i couldn't edit the svn repository directly on the server like i could with cvs, then slowly not being annoyed when i realized i didn't actually have to do that any more, lol. for some reason i remember having to fix broken cvs repos a lot.

heh

i had to write some web stuff today. i learned how to set up and configure node.js, pm2, and express, and then wrote it with node.js, all in less time that it would have taken me just to get a boilerplate java ee setup ready to start. i have so much free time now. that was so cool.

Shog9

02:20

Don't worry. In another 10 years, folks'll have managed to lard up JS with enough crap to make it comparable in overhead with Java.

Jason C

@Shog9 if i'm still programming in 10 years i'm going to order something from amazon, grab the drone when it arrives, let it take me up to about 300ft or so, and just... let go.

Shog9

The drone will be running JS2020, and will be too heavy to fly.

I was on the last problem of my Linear Algebra final. I just finished finding a family of left inverses with obscenely awful fractions. Then I saw I computed the matrix for the right transformation but between a subspace with a dimension one lower than it should be. Now I need to recopy my work and do the ugly computation again with a much larger matrix :(

:((((

D':

This final is literally taking me 10 hours to do.

user315433

Ugh. Inverting matrices by hand, what size?

bjb568

3x4, the complete family of left inverses

With fractions.

We literally didn't cover this in class either.

Of course, I can figure it out from (B is the inverse I need to find of A) CA^TA=I3; B=CA^T=(A^TA)^-1A^T, then use analytic sorcery to parametricise the family.

user315433

I was confused because for me, 3x4 mean 3 rows, 4 columns... that wouldn't have a left inverse.

bjb568

This is supposed to be Applied Linear Algebra. Useful algorithms for solving real-world problems involving LA. But this is just arithmetic with boxes around it.

@zaq Oh whoops, 4x3.

user315433

Heh, I teach a course called that, too.

user315433

03:40

It has some fakey applications to justify the name.

user315433

Well, least squares solutions are useful in general.

bjb568

My course was like this.
- 2 weeks of really simple "this is gaussian elimination"
- LU factorization & elementary matrices, i.e. theory and an algorithm to memorize
- Projections, i.e. theory and three algorithms to memorize (plus like one day of applications)
- Forever of eigeneverything
- Finally legit applications of linear DEs and quadratic forms

It really should have just started with the eigenapplications and skipped over the confusing theory stuff that the engineers just aren't going to get.

user315433

I never actually did this left inverse thing myself, but my inclination would be to transpose the problem (BA=I_3 iff A^T B^T = I_3) and then it's just finding general solution to linear systems of 3 equations with 4 unknowns. The RHS are the three basis vectors. All systems can be dealt with at once by doing RREF of the matrix, simultaneously applying same row operations to RHS matrix.

bjb568

Meh, ok, that should be a bit easier.

Honestly, I can't imagine half those students getting above maybe 40% on this final.

Great for me if there's a curve and I don't die from exhaustion before finishing it.

Thank FSM, there's no more fractions introduced by making the matrix bigger.

bjb568

04:04

Yay, it worked out well. Apparently this was the method I was supposed to use.

bjb568

04:26

Finally done.
