Proposal: Boy Scouts Should This include all Boy Scouting organizations (basically any organizations that participate in the World Jamboree) or just general "Scouting", and include Girl Scouts, Traillife, American-Heritage Girls, B-P scouts, etc?

RenderSettings

Ah, ok. So you can roll back pip packages and stuff via git?

@RenderSettings Don't know but you can track when these pip packages and stuff were installed.

And you can (try to) use bisect to find out what caused a thing.

But also you can track source code. :-)

I'll cut out the magic generator command:

virtualenv . && git init && git add . && git commit -m "Initial commit"

Install virtualenv if needed, of course.

@epicTCK wat

that makes no sense

that's like calling the baseball in japan

'not baseball', because they don't compete in the MLB

No, trail life members do not go to Boy Scout world jamboree because they are not boyscouts

@epicTCK that's why the site should be called "Scouting"

5:11 PM

well then post that here: discuss.area51.stackexchange.com/questions/23444/…

Upgrade and tracking of a package will go along the lines of:

./bin/pip install --upgrade pip && git add . && git commit -m "Upgrade pip"

@zyabin101 unless you're adding new files you can just git commit -am

@orlp Sorta.

and git commit -Am is git add . && git add -u

Gold (linker)

gold is a linker for ELF files. It became an official GNU package and was added to binutils on March, 2008 and first released in binutils version 2.19. Gold was developed by Ian Lance Taylor and a small team at Google. The motivation for writing gold was to make a linker that is faster than the GNU linker, especially for large applications coded in C++. Unlike the GNU linker, gold doesn't use the BFD library to process object files. While this limits supported formats to ELF only, it's also claimed to result in a cleaner and faster implementation without an additional abstraction layer. Complete...

I want it to deform and not un-deform.

Q: Minimum Activity Requirements for Area 51

After you've submitted your proposal below, here is all you'll need to get started:

5 example questions you would like to ask on this site
5 users who are willing to 'follow' this proposal
Proposals that do not meet these requirements within three days after submission are subject to removal. Note that abandoned proposals which receive no activity for a period of 30 days may also be removed.

You can read more about the site creation process here.

Also known as the 'non-starter proposal' check. There are a lot of unsupported proposals filling the pages of Area 51. It's not that these proposals are necessarily a bad idea, it's just that Area 51 doesn't always supply the built-in audience to create every site. Maybe the author underestimat...

Does anyone know if this sequence is in OEIS? (decimal equivalent)

jsfiddle.net/yd2329hg

We need an English word for a construct like "A ? A : B". "Google it, and if there isn't a solution, then ask on Blender.SE." My use of "and/or" technically allows for asking on Blender.SE without Googling first, which is not what one should do.

that is binary counting???

counting up in binary is in OEIS, yeah.

@Sp3000 I don't think that's quite correct

I want that sequence in decimal

You won't find 00 anywhere, so that's the closest you can get

I want to create a animation like those "spacetime deformation" ones, but I am stuck on creating "spacetime". (a mesh/plane). I created a plane, gave it a soft body, collisions, and a passive rigidbody. A cube with a rigidbody and collisions will land and deform the mesh, but it snaps right ...

@CᴏɴᴏʀO'Bʀɪᴇɴ -1 VTC original question as unclear :P

5:46 PM

9 mins ago, by Cᴏɴᴏʀ O'Bʀɪᴇɴ

Does anyone know if this sequence is in OEIS? (decimal equivalent)

not unclear :P

Yeah.

it is 1,2,3,4,5,6 ...

My jolf answer of it was easily cracked.

I took that to mean 0,1,00,01,10,11 where 11 is decimal 11

...7,0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,...

@Sp3000 Oh, I see.

Not VTC worthy tho :P

:D this sequence is just parseInt((a + 2).toString(2).slice(1))!

in binary

that's rather elegant

Hmm. It seems odd that OEIS wouldn't have a sequence with 00 in it. I guess it makes sense if it's only a resource for finding more information on a sequence you happened to discover.

Why? 00 = 0 = 000000000000000000000000.

They're the same integer

5:51 PM

What I mean by that is OEIS has integers only, so no extraneous leading zeroes

I wonder if there's an OENS - Online Encyclopedia of Number Sequences. Floats are missing too...

OECS - complex numbers!

So, there's a one-to-one correspondence between Z ^2 to N; is there one from Z ^3 to N?

Er... did you mean R^2 to C?

No, this is completely irrelevant :P

Trying to code three variables into a single integer

@CᴏɴᴏʀO'Bʀɪᴇɴ There is no one-to-one relationship between Z^2 and R. The former is countable, the latter is uncountable.

5:55 PM

@El'endiaStarman Sorry, not R. I meant N.

I'm on 3.5 hours of sleep >_<

Then yes, diagonalise more

Then yes, there is. You can interleave digits.

Given a positive integer k > 1 and a non-negative integer i, generate a k-tuple (or k-dimensional vector) of non-negative integers. For every k, the map from ℕ to ℕk, must be bijective. That is, every input i should produce a different tuple, and every possible tuple must be produced by some inpu...

@quartata oh. so by extension, there is a correspondence between Z ^k and N?

@CᴏɴᴏʀO'Bʀɪᴇɴ There is a 1-to-1 correspondence between any two countably infinite sets. In particular, there's one between Z^k and N for any finite k.

But yeah ^
