@Dennis This is how I feel about my production code from 5 days ago.

Alex A.

The digital crickets in here are nearly deafening.

Alex A.

My girlfriend's dad used to do maintenance on mass spectrometers for national labs. He once had to go to the Hanford Nuclear Plant. He found a tumbleweed, thought it was neat, and put it in his bag. But on his way out, he had to be scanned for radiation. His bag made the sensor go nuts. Turns out it was a highly irradiated tumbleweed.

That's what I have to say about tumbleweeds.

Reto Koradi

well, that's probably much more than most people have to say about tumbleweeds ;)

aditsu

02:38

there's a tumbleweed badge

Alex A.

I'm glad that I don't have that badge on any site.

It would probably be irradiated due to cross contamination.

Reto Koradi

ah, that's a question badge. I think I only asked one question on one site so far. on SO, I'm at over 1000 answers and 0 questions

Alex A.

:O

Reto Koradi

Necromancer is another badge that does not sound very flattering. I do have that one on SO

aditsu

I am a silver necromancer on ppcg

Sp3000

02:56

Necromancer's easy on PPCG if you answer a tips question :)

Reto Koradi

hey @Alex, I see an upvoted comment from you about Sudoku solvers. I wrote one a few years ago. unfortunately lost the code. it was pretty fast. how fast is yours?

Alex A.

@RetoKoradi I actually dislike sudoku too much to be interested in making a solver. :P

But if I wanted to participate in sudoku, it would be by programming a solver.

I think it was @Pietu1998 who was saying that he has a really fast sudoku solver.

Reto Koradi

well, I solved them manually for some time, too. was reasonably good at it. not sure why you would dislike them if you're on a site with "puzzles" in the name :)

Alex A.

Oh I like puzzles, just not ones that infuriate me.

Doorknob

@RetoKoradi Programming Puzzles & Code Golf != Puzzling ;)

Reto Koradi

03:10

@Doorknob Sure. But I could imagine that similar kinds of people would like both activities.

Alex A.

A lot of folks here are active there too.

Reto Koradi

Computers are much better at Sudoku, though. My solver solved about 2000/second from a benchmark dataset. And those are ones that are too difficult for almost any human to solve manually.

Alex A.

Well if that's not badass, I don't know what is.

Nice work. :)

Reto Koradi

Apparently some people were at about 5000/second. Of course it depends on the hardware, but others had definitely come up with faster algorithms.

Alex A.

Sounds like you and @Pietu1998 should talk algorithm-advice the next time you overlap in chat.

Reto Koradi

03:16

If it's ok to pimp your own answers, this recent one was a really fun algorithm problem codegolf.stackexchange.com/questions/51728/…. Probably more work than I ever spent on any other SE answer, though...

Dennis

@AlexA. :P The gesture suite for my touchpad aside, I don't think I've ever written production code.

Alex A.

@Dennis :O What do you do for work? Are you not a programmer of some kind?

Dennis

I'm a Mathematician. Just finished my Ph.D.

Sp3000

@RetoKoradi My personal problem with Sudoku and other Nikoli puzzles is that it's very algorithmic to solve for most. Sure, you might get a clue or two by nice leaps in logic, but half the time it's rows/cols/squares/pairs/trips/wings and whatnot

Dennis

Not counting LaTeX, I've written zero lines of code for work.

Alex A.

03:27

Congrats on finishing your PhD! That's fantastic!

Dennis

Thanks!

Reto Koradi

@Sp3000 That's true. When I solved them daily, I had a well defined strategy. Looked for the same kinds of patterns in the same order. It was fairly routine. In a way, it actually helped me switch my mind off, even though it required a lot of focus.

Alex A.

Sp3000

:) doesn't mean I don't like Sudokus in general though, just not by hand for me

Dennis

:D

Sp3000

03:29

(Unless there's a twist)

Reto Koradi

Mathematicians scare me. :) Actually, sometimes I wish I understood more of it. Who was that a few weeks ago who used some crazy math to solve a problem? I believe it was once of Martin's diamond pattern things. I didn't understand half the words he used.

Dennis

I don't think I'd be very interested in code golf if I had to code for work. I don't participate on Math SE at all...

Alex A.

@RetoKoradi @PeterTaylor

Reto Koradi

Yes, that was him.

Sp3000

Peter is pretty crazy. Crazy good.

Alex A.

03:31

Crazy smart.

Reto Koradi

I worked quite a bit with physicists. Some of those are very smart as well.

Alex A.

@Dennis So do you work in academia? What does your work as a mathematician encompass?

@RetoKoradi @MartinBüttner studied physics!

Reto Koradi

More seriously, I was actually kind of interested in studying math as well. But the career options seemed fairly limited. And since I was about equally interested in CS, I went for that.

Sp3000

Double degree - best of both worlds. At the expense of time and money.

Alex A.

I studied math. I didn't give a shit about career opportunities.

And then I graduated and needed a career.

Dennis

03:34

@AlexA. Pure math, almost exclusively. I'm currently researching (Topology) and teaching a couple of courses.

Reto Koradi

We had to choose another subject where we had to take a number of courses. Not sure if that's similar to a "minor" in the US. I took numerical analysis. Learned about eigenvalue algorithms, finite element algorithms, and all that fun stuff.

Dennis

@AlexA.What do you do for work?

aditsu

I often solve sudokus by hand to kill time (when I'm out and waiting)

Chris Jester-Young

@AlexA. /me has a stats major. Luckily, a lot of that stats major was spent working on R. :-P

aditsu

I used to be a math guy in school, but programming was way more attractive

Alex A.

03:40

@ChrisJester-Young I did a stats minor and now I'm in a distance master's program in stats. :)

@Dennis Currently I'm a programmer in medical research but I'm looking to change careers.

Chris Jester-Young

@AlexA. :-D

Alex A.

High five for stats!

o/

Chris Jester-Young

@AlexA. I was lucky to be doing stats at the university that invented R, at a time when R was nascent.

Reto Koradi

@AlexA. What kind of medical research? I worked for a medical device company for a while.

Chris Jester-Young

So my honours project was to actually do work on the R core. :-)

Alex A.

03:42

@RetoKoradi Currently I work at a nonprofit group that, in a nutshell, does statistical consulting for cancer researchers.

Chris Jester-Young

Fulfils my interest in programming, while still doing something marginally statistical.

Alex A.

@ChrisJester-Young That's awesome!!!

Chris Jester-Young

@AlexA. I know; back then I didn't know R was going to get so big.

I really liked the language, though, so I championed it whenever I could.

Alex A.

I haven't seen you doing much R golfing. ;)

Clearly code golf > core dev

Chris Jester-Young

@AlexA. Well, so, I don't work with R so much any more, so it's gotten rusty. :-(

Reto Koradi

03:45

@AlexA. I see. That's quite different. I'm more interested in medical imaging.

Alex A.

@RetoKoradi Medical imaging is really interesting. I took a Coursera course on statistical analysis of fMRI data, and that was fascinating.

Chris Jester-Young

(Sorry, I had to edit Reto's comments some so that the thread linkages are in place. OCD. ;-))

Alex A.

Someone has got to tell me why V3Fd.PG+N1Iqdwd isn't working. I'm loosing my mind

Dennis

vihan1086

@Dennis loop through all permutations of the alphabet and check if a permutation is the same as the input

Maltysen

@vihan1086 w calls input() again every time

you want z

this can be much shorter with filter

vihan1086

@Maltysen ohh, thanks. This is my first Pyth program so it'll probably be very bad

Is there a way to do os.system in Pyth?

Chris Jester-Young

Sure, with $. :-P

@xnor Okay. Try using a manual <pre><code>...</code></pre> block. It may or may not work, but you won't know till you try.

I say "trivially", but of course i mean "The first one to write a working Unary answer wins"

Sp3000

08:34

btw I tried to implement TIS-100 in Python when I was bored in my lecture earlier, but couldn't figure out the exact termination condition

(HCF?)

Martin Büttner

ahh, right

Sp3000

It's probably easiest to make it terminate when it all deadlocks, but that's not quite right

Martin Büttner

I checked the story and everything for hints but didn't consider just checking out the name of the achievement :D

Sp3000

:P

Martin Büttner

@Sp3000 I think it just terminates when the specified output is printed correctly

I've written some image-based ones that rely on that (they'd continue producing garbage, but at some point the image buffer is correct and the code terminates)

Sp3000

08:36

That would be an amazing language spec. "Terminates if and only if the correct output is given"

Martin Büttner

:D

Sp3000

Not very useful though :(

Martin Büttner

just use HCF then ;)

Sp3000

Hm... maybe deadlocks and no data is transferring?

Martin Büttner

hm that would work as well, although I'm pretty sure the game doesn't actually terminate in that case

(because the idle percentages keep changing afterwards)

why were those two steps required at all?

can stackexchange not post otherwise?

Geobits

It typically doesn't. He needed it to say something so he could edit it into something funny/appropriate/whatever-you-call-it.

There may be other triggers for it (I don't know), but freezing is definitely one.

Doorknob

I did no such things. The bot simply temporarily became sentient. :P

O.O

Geobits

Or that (though the edit history somewhat contradicts it).

I still don't understand :/

The program on Channel 4 about robots?

It's another way of saying that Skynet was just born and we're all doomed to a post-apocalyptic hellscape where 30 years of war will ultimately develop a closed time loop.

That's not about Skynet at all, is it?

what is the general term for length, area, volume etc.?

Alex A.

Physical properties?

Dimensions?

Lebesgue measure

In measure theory, the Lebesgue measure, named after French mathematician Henri Lebesgue, is the standard way of assigning a measure to subsets of n-dimensional Euclidean space. For n = 1, 2, or 3, it coincides with the standard measure of length, area, or volume. In general, it is also called n-dimensional volume, n-volume, or simply volume. It is used throughout real analysis, in particular to define Lebesgue integration. Sets that can be assigned a Lebesgue measure are called Lebesgue measurable; the measure of the Lebesgue measurable set A is denoted by λ(A). Henri Lebesgue described this measure...

@MartinBüttner right, I arrived to "size" which is a lot less precise
