bai!

Anyone knows something that converts a base64 encoded WOFF to a regular TTF (or OTF) file? Not for a challenge, I really need this.

@EasterlyIrk bai!

@flawr do we have to worry about the directions of the eigenvectors of P?

@EasterlyIrk bye!

@flawr I mean is there a risk you would get a sum that is too big you ignore the direction of the eigenvectors?

Not really. As long as we 'go' an equal amount in each directin=)

@flawr this sounds really interesting and no, I didn't know it before

7:12 PM

@Downgoat chat.stackexchange.com/transcript/message/28778798#28778798 Could you help me in JS?

@Lembik Oh sorry, I do not mean the eigenvectors, I mean the principal components!

And these are by definition orthogonal!

@CᴏɴᴏʀO'Bʀɪᴇɴ what is the transformation?

(Replace eigenvector with principal component in the lengthy message, I cannot edit anymore.)

@Downgoat Basically [0, 1, 2, 3, 4, 5] => [[0, 3], [1, 4], [2, 5]] => [0, 3, 1, 4, 2, 5]

@flawr There is some relationship between the principal components of M^T M and its eigenvectors

that I don't really understand

@flawr but it all sounds awesome :)

7:15 PM

@QPaysTaxes Split?

@Lembik Well yes, the principal components are the eigenvectors of M^t M

That's such a generic term o_o

SORRY BAI

@flawr right.. so they are the same

@CᴏɴᴏʀO'Bʀɪᴇɴ [].concat(a.filter((_,i)=>i%n==0),a.filter((_,i)=>i%n==1))

I don't know 100% if that works though

@flawr but I am intrigued by what your approach will give you.. all I would say is, please implement it!

7:17 PM

@Lembik Well now I hope my argument is consistent. I'm now gonna check with your test cases=)

@flawr great! :)

CSᵠ

less than 1h

I can make more if you need them

@Lembik Out of memory. hahaha.... it seems my testing program is not that efficient yet^^

@EasterlyIrk =(

@Lembik Fu*ck I forgot something. I always imagined a normal distribution which is obviously always scaled to integrate to 1. That means the constant factor gets smaller as the number of dimension increases. Which is not the case in your challenge. But It shoud still be possible to extract an upper bound.

@AlexA. I finally know why you ran into that SSL issue. It's not Safari's fault. Quite the opposite. Safari, Firefox and every mobile browser has a stricter SSL chain policy than say Chrome or IE etc. Even if the cert is valid and verified, the browser will still refuse the connection, if the server doesn't serve all certs (Chrome etc. just download the missing ones from the CA).

You can check any site here. If there is a broken chain, the rating will be "B" and there's a warning. If not, the rating will be A or A+.

TL;DR: It's a feature, not a bug.

@Mego The mods are dead! Long live the mods!

@flawr this is sounding more exciting by the second!

@Lembik Right now I'm trying to make an estimation considering the evaluation on integer points as basically a multidimensional "rectangle-quadrature" rule.

@flawr I see what you mean

The bad thing is that after the fun part I'd also need to program the stuff^^

@flawr feel free to use some heavy libraries. Do you use python or another language that has lots of math libraries?

7:30 PM

Oh no, I do not really know anything except matlab for number crunching =/

zyabin101

@Mego s/4/0/

@flawr ah ok :) Well feel free to submit an answer in matlab and the community can work out how to translate it into something open

You could run it on Octave=)

(but as I said, slower)

I am happy to try that too

I am just very flexible :)

Wait, @ChrisJester-Young will you not be a mod anymore?

@DrGreenEggsandHamDJ Nope, his time is up.

We should make a memorial for @ChrisJester-Young

Wth? Moar SU rep.

@Dennis on old posts you mean?

@Dennis I think somebody's serial voting to get you banned :P

*suspended

Dennis

Very old posts. I usually get +10 or +20 in a week, but I got +65 today.

That sounds so awful...

language learning is already a better site than PPCG :c

O.o

@Downgoat have another look in a week ...

^

this is what pretty much every first day of private beta is like

7:43 PM

Was just about to ask how old they are.

(plus, LL is a popular topic)

:/

@Downgoat Not enough challenges.

@El'endiaStarman zero days

oh, ninja'd

Yeah, there's your problem. :P

7:44 PM

In 15 minutes we will know the truth.

@Dennis odd... I've been getting some more votes (probably over 10 in total) on my math.SE question the past few days, and I assume it's because of people checking out the candidate profiles during the election.

Dennis

Hm, maybe.

ah, that's why I should have nominated myself

Anonymous

I dunno, I haven't gotten much rep gain lately

I got my first gold badge and I didn't even nominate myself

7:45 PM

@Downgoat For comparison, Christianity.SE had 64 and 71 questions questions on the first and second day of private beta.

oh, in case any of you are interested: That google foobar I participated in a while ago did pan out. I actually have a phone interview in a week

congrats :)

(I have no clue what foobar you're talking about, but it sounds like it worked out for you)

I was searching for something python related and the search results had a "you speak our language...want to try out a test?"

@NathanMerrill Oh nice! Congrats!

which, if you pass the first 3 levels, allows you to accept a recruiter to contact you

Zach Gates

7:49 PM

A Python job, you say? Nice

they actually also do it on Java searches.

I'd be cool with any job in Java, Python, or Go

@NathanMerrill Sounds like a good way to start Global Thermonuclear War.

@NathanMerrill brb doing Java searches

Zach Gates

^ s/Java/Python/

still no google job >:U

7:53 PM

I'm pretty sure avocad is on their "Do not contact" list

you could apply for a job, you know? :p

@Downgoat What accent should this be read in?

plz halp how job Goog i try for 1 hour but no job

@flawr goat accent?

@Undo yes, very. People discriminate against goats in the workplace industry

so, I've read candidates' answers, but no clear winner has emerged

such disappoint

@aditsu are you also having trouble selecting which candidates to vote for?

only for 3rd place

7:55 PM

@aditsu who did you vote for 1. and 2.?

first 2 were kinda reserved :p

okay, final question: Do ya'll want results posted in here or CHQ?
