@KyleKanos I'm never around when the flags fly...

Kyle Kanos

2:10 AM

@tpg2114 Today's flag wasn't nearly as interesting as the other day when many flags (and locusts) were case.

This one was based on someone being in a bad mood (or at least seeming to be) and thinking every suggestion was serious

Helpful hint to all: probably around 90% of what I say is facetious, sarcastic, or sardonic. When in doubt, take the position it's not serious.

tpg2114

2:27 AM

@KyleKanos Isn't that the rule for all chat rooms on the internet?

Kyle Kanos

@tpg2114 Probably

But I suppose if someone persisted in calling me pathetic for lamenting my job, I'd probably become grouchy as well and snip at most people & their comments

tpg2114

I'm having hard-core programming block right now. I guess that's the problem of being overwhelmed with 4 different projects in 3 languages :/

Kyle Kanos

I've become bogged down with post-processing stuff

tpg2114

And there isn't a drop of alcohol in the house... not sure if that's helping or hindering me though

Kyle Kanos

My Jameson is running low :(

vzn

2:31 AM

"sabre tooth" has a thin skin...

(dont know exactly what was said though, was something removed?)

tpg2114

Let's not poke the bear again @vzn. I'd just let it go

vzn

its no poking. hes overreacting.

tpg2114

@KyleKanos I don't like Jameson much actually.

I usually keep Jim Beam or Wild Turkey around

And some Sweetwater beers

vzn

dont take it out on anonymous chat users if you hate your job. (hey man sympathize w you on that one)

touchy!

tpg2114

@vzn And continuing to discuss it can just lead to more "overreacting"

vzn

2:33 AM

hes gone its no big deal

tpg2114

Nothing good could come from continuing down this thread of conversation

vzn

didnt ping him. now that would be poking.

Kyle Kanos

@vzn there's an history though

Just don't worry about it.

tpg2114

Everything is logged and it's really not hard to catch up on things

Kyle Kanos

It's not a big deal

@tpg2114 Irish whiskeys are pretty much the only hard liquor I drink

Which is kinda shame because I don't think they're allowed on the diet

vzn

2:34 AM

its all fun-n-games until someone gets flagged lol

tpg2114

Ironically, that's one of the only ones I tend not to drink

Kyle Kanos

Only vodkas, for some odd reason

vzn

was lol at the meme potpourri before that

tpg2114

I don't care for vodka much. Not that it's bad, but it's just kinda... nothing. Like why bother

Kyle Kanos

Actually, it says Scotch & Vodka

So I guess I can survive that

But no beer :(

tpg2114

2:35 AM

I've been warming up to gin lately. Took me awhile to build a taste for juniper

Scotch is good stuff

When I'm at bars, it's usually scotch and soda or gin and soda.

The bar near me, they see me walk around the corner and my drink is on the bar before I even get there... I suppose that's probably not a great thing

Kyle Kanos

I rarely go to bars (too 'spensive)

Plus the whole "I have a wife & 4 kids" thing

tpg2114

Yeah, that's definitely true. But I learned if you make friends with the bar tenders, it becomes much cheaper

My bill is always much shorter than what is given to me

Kyle Kanos

Yeah, I've seen that happen before

Partly b/c my eldest brother is a bartender

tpg2114

I was out with a group of bartenders after they got off work once, and somebody I knew from Tech saw me and later asked why I would want to hang out with people who weren't nearly as educated

tpg2114

2:40 AM

I had to explain at great lengths that sometimes it's nice to go have a conversation that isn't an argument about equations, or which superhero is better than which

Kyle Kanos

@tpg2114 Hmm, they're clearly DC fanboys. Marvel is soooo much better

tpg2114

I never actually got into superheros

I didn't like Spiderman at all

Batman, to me, is just... not a superhero. Like Iron Man, he's just a guy with a lot of time and money and cool toys. P

Plus, he's totally not a good guy. He's only doing it for revenge

He only fights crime because he's looking for who murdered his parents. If beating up sheep and little kids would lead to finding who did it, I'm positive he would be doing that instead

Superman is really one of the only, true "superheros" but he gets kinda old fast. There's only so many different ways one bad guy can try to get at him with one green rock.

The Flash was cool, but I never really read anything there. The Green Lantern seemed sorta lame

@KyleKanos Somebody sent me this link thinking it was cool. But then I saw their recommendation for learning Fortran: linuxlinks.com/article/20150201134045961/BeginnerBooks.html

I was instantly disappointed

Kyle Kanos

Batman's not looking for the guy who murdered his parents

He's looking to prevent other kids' parents from being killed by criminals

@tpg2114 Definitely a fail there

Wonder if I can email them & recommend at least Adams' book

vzn

"boring" superman

T Abraham

@alarge that doesnt mean I don't want to put effort into it.. in fact this problem has been on my mind for a long time.. But I also have other stufff, mainly college work.. ok fine, I will try to put more effort...

Kyle Kanos

2:54 AM

@tpg2114 Actually, it looks like they're thing is recommending free books, so Adams' book is out. But why a Fortran 77 book?

tpg2114

@KyleKanos Exactly. And if you go to the bottom little link deal and click on Fortran, they have like 9 books I think

And some of them are 90/95

All free

Kyle Kanos

I'm looking at them now

I seem to recall seeing Jorgensen's book before

tpg2114

So why they took the F77 one, who knows. Most of them are F77 books though

But I guess that the vast majority of Fortran out there is probably still 77 (or older)

Kyle Kanos

Interesting...Jorgensen's book is CC-by-SA

tpg2114

That's kinda cool

Derive work from it!

Kyle Kanos

2:59 AM

From Chapter 1: This text utilizes the Fortran 90/95 standard. Older versions of Fortran, like Fortran 77, are not referenced. The older Fortran versions have less features and require additional, often burdensome, formatting requirement

tpg2114

Fixed formatting is seriously miserable

Kyle Kanos

But, given the origins of it, it makes sense

tpg2114

Sure

Kyle Kanos

But in the modern sense of programming, it's quite the burden

tpg2114

But now that we're like... 50 something years removed from punchcards, we probably shouldn't be tied to them

T Abraham

3:00 AM

@vzn u gossiper..

tpg2114

Yeah, nothing about this sounds fun:

Q: How did programming work when programmers used punchcards?

I saw this: Learning to program on punchcards and I've seen this: http://en.wikipedia.org/wiki/Computer_programming_in_the_punched_card_era but they leave much to be desired. Can anyone explain to me how programmers programmed when they used punchcards? Specifically, the system of input comput...

history

dmckee

@tpg2114 Slowly.

tpg2114

Maybe, just for fun, before I graduate, I'll find a way to print out our lab's code on punchcards

vzn

wild trivia... punch card tech started out on... weaving looms. leading to the luddite protests

dmckee

But then programmer time was cheap compared to machine time then, so it wasn't a big deal.

tpg2114

3:05 AM

Just so I could store it somewhere and try to convince my kids some day that that's how we did it because touchscreens were too hard to use.

dmckee

I have actually punched a deck, gotten the error report back thrity minutes later and then debugged the deck.

Once.

To say I had done it.

It's far worse than using a line editor.

tpg2114

That sounds absolutely miserable

Kyle Kanos

My dad worked punch cards in undergrad

tpg2114

I mean, from an engineering perspective, it's kinda cool to turn something physical like that into something computational

dmckee

@tpg2114 It's like anything else so primitive its novel. Fun the one time, but you'd hate to live it.

tpg2114

3:07 AM

@dmckee Plus I'm sure, at the time, it was hard to envision something else that was clearly superior

It would be like us saying now "Emacs/vim is cool and all, but it would be way better if the computer could read our minds and program that way"

Kyle Kanos

I don't want my computer to read my mind

tpg2114

Or "It's great that I can program a computer, but it would be better if the computer could program itself" -- which is actually sort of happening and is pretty crazy

dmckee

@tpg2114 Yes and no. Card punches and readers persisted for quite a few years after teletypes were available because of the cost issue. Plus the deck is off-line storage which can matter when memory is rare and expensive.

tpg2114

@KyleKanos Google already does it. I get 2-3 words into a search and it predicts quite scarily what I am thinking

vzn

google is )( that close to skynet o_O

Kyle Kanos

3:10 AM

@tpg2114 That's not mind reading, that's prediction based on past history

vzn

"deep learning"!

dmckee

Spooky enough for me...

tpg2114

@KyleKanos Which is sufficient to read one's mind

If it can learn from my patterns and can predict my thoughts, that's mind reading to me

Kyle Kanos

hmm

That's a fair point, I suppose

tpg2114

I guess one could argue it's not exactly the same as it's not reaching into my brain and "hearing" what is going on. But they are at least equivalent

But since we know the brain is really just a bunch of electrical and chemical signals, I would think pattern recognition and prediction is as close to "hearing" thoughts as we'll get

Kyle Kanos

3:13 AM

Wow...XeroKynos is at it again. He did a 100% FF8 run Sunday -> Monday and started another 100% run 2:20:00 ago...

It's a 12 hour run

tpg2114

Do you like FF8 specifically, or do you like speedrunning in general?

Kyle Kanos

Mostly speedrunning RPGs

FF series is probably the most popular

tpg2114

I stumbled across ADGQ for the first time this year. I've had YouTube running through the previous ADGQ/SGDQ playlists nonstop since then

Good background noise, I have my laptop hooked up to my TV so I have it fullscreen there while I work

Kyle Kanos

And I enjoyed most of the FF games I've played (1, 4, 7, T, 8, 10).

I watched some of the ADGQ live this year. Couldn't catch some of the ones I wanted to watch due to times

You know, having the game start at ass-o'clock

tpg2114

Yeah

youtube.com/user/gamesdonequick/playlists

They've got almost all of this year's up

They did FF6 in the SGDQ 2014 at the end, it was a 7 hour run

These guys have a lot of the older marathons:

youtube.com/user/AGDQuploads/playlists

I like the Zelda games, even though I don't know that I've played one

Kyle Kanos

3:19 AM

Yeah, I did actually catch the end of the FF6 run live

tpg2114

I think AGDQ ended up at close to $1.7 million this year

That's pretty awesome, they do a really good job

Kyle Kanos

They did break $1.5, but it wasn't announced on stream until the Zelda runs

Which was kinda cool to see someone do Child Link blindfolded

tpg2114

Yeah, they kept getting more money after it ended

I watched the Paper Mario run from SGDQ14 yesterday, that was a long one too. Like 6 hours

I never had a Nintendo anything, so I missed out on most of those games

We had a Genesis and the PlayStations

Kyle Kanos

^ Same here

FTW:

Herzog Zwei

Herzog Zwei is a Sega Mega Drive-exclusive game by Technosoft, published in 1989 (released in North America in early 1990). It is an early real-time strategy game, predating the genre-popularizing Dune II. Herzog Zwei is also considered one of the best two-player Genesis games, combining the arcade-style play of Technosoft's own Thunder Force series with a simple, easy-to-grasp level of strategy. Herzog Zwei (German pronunciation: [ˈhɛɐ̯tsok ˈtsvai]) translates from German to "Duke Two". It is the sequel to Herzog, which was available on the Japanese MSX and PC-8801 personal computers. ==...

My brothers & I hated that game until we figured out how to play it

tpg2114

Never played that one

Kyle Kanos

3:24 AM

It just didn't make sense to us, but it's basically a strategy game like Warcraft or Dawn of War

tpg2114

I played Dune II

Kyle Kanos

Joe Montana Football?

tpg2114

We actually had Madden '92

Kyle Kanos

Fake punt every down = win

No machine learning on that game, defense picked based on formation

tpg2114

We used to make it super snowy and our guys would get injured, then the ambulance would drive around the field and mow down everybody else because it was slippery

I think Road Rash may have been one of the first games we got

Kyle Kanos

3:26 AM

Road Rash was fun

tpg2114

That was a kinda fun game that really doesn't have anything else like it

I miss the Twisted Metal and Jet Moto series on PS too

Kyle Kanos

I fell off my bike playing that with my brother

tpg2114

Haha, yeah, we used to play it too...

Kyle Kanos

Not really playing it, just jokingly saying we were doing it

tpg2114

We didn't whip each other with chains or clubs of course

Kyle Kanos

3:28 AM

And I threw a puch, turned the wheel, face-plant

tpg2114

Yup... been there, done that

Kyle Kanos

Twisted Metal got boring once someone told me the cheat code to get your special weapon.

tpg2114

I still have all those codes memorized

Unlimited ammo, unlimited weapons

It's was still fun when playing with people who also knew the codes

TM2 was by far my favorite

Hold down L1, R1 and then press up, down, left, right, right, left, down, up.

That was... weapons I think

Ammo was the same D-pad code while holding L2 and R2

Kyle Kanos

Sounds about right

tpg2114

PS3 actually sells a lot of the old PS and PS2 games

For download

Like $5 each I think

Kyle Kanos

3:32 AM

My brother picked up FF7 on the PSN

Don't think he beat it though

I'd like to get the steam release, but that'll have to wait

tpg2114

I'm not sure I ever played any FF either

I must have played a little bit of them, but I haven't owned any

Kyle Kanos

It's pretty much the only game I played throughout HS and early college

tpg2114

I was doing the WC3, StarCraft thing then

And some FPS games on the PC like Ghost Recon

Kyle Kanos

I did pick up MGS & MGS2 when I got the PS2

I also got Soul Calibur because a girl I liked played it (and schooled me every time she played me)

tpg2114

I didn't like any of the Metal Gear series

I don't know why, I just never got into it

Soul Calibur was fun

Kyle Kanos

3:37 AM

Everything past 3 was dumb, from what I've seen streamed. Even MGS2 was a bit silly because you weren't playing as Snake for most of the game

tpg2114

It's pretty hard to out-do Mortal Combat and Smash Bros though

I remember being annoyed by the number of cutscenes

I felt like 75% of the game was cutscenes

Kyle Kanos

I honestly don't remember. After I lost interest in the girl, I lost interest in the game

Or were you talking abuot MGS?

tpg2114

Sorry, MGS

Kyle Kanos

Oh yeah, definitely a lot of cut scenese

But they're skippable

Only the ear-piece video thing wasn't quite skippable, you could turn off the speech and speed through it though

tpg2114

My brother loved it, I just didn't like it for some reason

Kyle Kanos

3:43 AM

Apparently the Wii version is amazingly broken for the first-person capabilities that weren't present in the PSX version. You can beat most the bosses in about 3 seconds by aiming

tpg2114

I never played a Wii much. I've played the Wii U a few times and it's cool because the game pad controls mirror the PS controller

But the pad is so darn big

I got my friend's son Lego Batman 3 for Christmas (Wii U) but he was having a hard time figuring out what to do so she made me buy it (PS3) so I could show him how to get through it

Kyle Kanos

My sister in law gave us her old Wii. Haven't used it much outside of being our DVD player (which it isn't very good at)

tpg2114

And the buttons have different labels, but they are mapped the same. I got way more excited than I should have about that

The Mario and DK games are fun on the Wii

Kyle Kanos

We have Mario Kart & the Wii sports, I think that's it

tpg2114

And they don't use the motion control part for most of it, you turn the controller sideways and use it like an old Nintendo controller

I didn't like Mario Kart where it made you use the controller as a steering wheel. It was too hard to drive

The sports ones are fun though

I want a PS4 but I can't justify buying it, and games, and then spending the time playing games...

Kyle Kanos

3:47 AM

Never tried it with a regular controller

T Abraham

@vzn ...

@tpg2114 I think it's nice..

@tpg2114 u like wii u? I never got it.. I hope to get it soon...

tpg2114

I just always struggled to make it work right.

@TAbraham I don't own one so I can't say. I just help my friend's son play

I don't like motion control for video games for the most part. If I wanted to exercise, I'd go exercise! :)

It was cool for some things, like the Wii Sports or the other one, I can't remember what it's called. Had cycling, canoeing, etc

Same idea though

Kyle Kanos

Sports Resort?

tpg2114

Yup! That one

I liked those games and the motion control was pretty cool for it

Kyle Kanos

Joey likes to fly the airplane in that one

He doesn't complete any of the objectives, but he has loads of fun flying it

tpg2114

3:56 AM

That's what matters right?

T Abraham

@tpg2114 yeah, it's cool.. like it too..

Kyle Kanos

Wish there were a way to make it fly w/o the time limit

T Abraham

@tpg2114 exactly...

@KyleKanos yeah..

tpg2114

It took me a long time to relax when I was helping him play games, he's 5 and didn't get most of the "objectives" of games. So I'd always get stressed out about not getting things... haha

But it's fun just to play whatever they think they're playing, and that's awesome

I'm more of a perfectionist in games. 100% or bust

Kyle Kanos

I always played casually

Never cared to get 100%

But never really cared to beat the game faster than I already did

tpg2114

3:59 AM

I never cared about speed so much

But I would spend like hours in a single Sonic level trying to figure out how to get a hidden ring somewhere

Just because it bugged me I couldn't find it

Kyle Kanos

You should see the TAS run of Sonic 2

It's insane

tpg2114

That's partly why I like games with mutually exclusive choices. There's a lot more replayability for me because you can't just go through it once and do everything

Is it on tasvideos?

Kyle Kanos

Actually, it was sonic 3

►

I saw it on youtube

tpg2114

OKay, I was having a hard time finding Sonic 2 ones :)

Kyle Kanos

The secret levels are o.O

tpg2114

4:03 AM

I loved this game when I had the genesis

I had all of the blue sphere collection minigames memorized

The stuff those TAS guys do is pretty awesome

The TAS at ADGQ this year was really impressive also

Kyle Kanos

TASbot plays Pokemon plays Twitch

tpg2114

Yeah

Was it last year that they reprogrammed super mario brothers?

Kyle Kanos

Actually, now that I think about it, I think Tas-ception was Super Mario Bros

tpg2114

They reprogrammed SMB to play Mario Brothers

Kyle Kanos

Yeah

And got it to stream twitch

tpg2114

4:11 AM

Yeah

I think the Mario Bros was cooler than an IRC client

Kyle Kanos

I don't think I've ever actually used IRC

tpg2114

We use it in our lab. I think I've been logged into it for like... 5 years without logging out

Kyle Kanos

o.O

tpg2114

It's effectively just like this here

But I use a terminal client. Because terminals are awesome

Kyle Kanos

I presume Linux comes with an IRC client installed by default, but I've just never seem to have needed it

tpg2114

4:15 AM

I think the only time I used it other than within my lab was to connect to an openSuSE tech support channel

Cause I couldn't get my printer to work

Kyle Kanos

Printers are overrated

tpg2114

But they were totally baffled by the problem. I ended up having to write a patch for their build system and wrote a whole long tutorial on their website

Took like 2 months

Sonic collecting blue spheres backwards is pretty awesome

Did you see that guy became a Tetris Grand Master?

Kyle Kanos

@tpg2114 That was the mind-blowing part of it to me. I really felt like they were showing off because they move the game ahead one frame at a time!

I did see most of the Tetris block

tpg2114

He's like the 5th person in the world to ever do it, the first one outside of Japan

Kyle Kanos

That was amazingly impressive

tpg2114

4:17 AM

So that guy, the one where he had to play through the credits?

Kyle Kanos

I sorta recall that

tpg2114

He just became a grand master today. You have to get that Master M ranking 4 straight games

To get Grand Master

Kyle Kanos

Oh

tpg2114

games.yahoo.com/blogs/plugged-in/…

Playing blind through the credits looks impossible

Kyle Kanos

It's guesswork,

tpg2114

4:20 AM

twitch.tv/kevinddr/c/5983832

Kyle Kanos

Wow

That game effs with you at the end there

tpg2114

I think it does it the entire time

You have to have an incredible mental ability to picture what's going on during the credits

Kyle Kanos

I guess I mean in showing him that he won GM title

It showed the titles, he knew it was had to be gold to get GM, shows him silver & then crashes out the gold

That is evil programming there

tpg2114

The whole thing is evil programming :)

He said during AGDQ that the credits are randomized

So you don't know when the credits will actually end

Kyle Kanos

Wow

Sadistic game devs

tpg2114

4:32 AM

I can only imagine what the after party is like for becoming a Tetris Grand Master...

Kyle Kanos

Alcohol & no more Tetris?

tpg2114

I guess that wouldn't make it any different than any other after party eh

Kyle Kanos

Probably not

9:26 AM

@DavidZ I just got the message that this question has been deleted. If you recall I answered that question and the answer was deleted. I thought you said this was temporary?

@DavidZ I'm referring to this conversation

David Z

Yes, deletion of the answer was temporary.

What happens to the question is entirely separate.

glance

Ok, but I suspect it was deleted automatically as closed with no answers, right?

David Z

Perhaps

I mean, I don't have any more information than you do regarding why it was deleted

glance

ok, so what happens is that you just "temporarily" delete an answer to the closed post, and just wait long enough so that the question having no answers get automatically deleted, problem solved? I mean, it's really not a big deal that my answer was deleted and I lost some rep in the process, I can live with it, but in these circumstances you could simply say that the deletion is (probably?) not temporary, so I can at least save the answer for another more "acceptable" question.

David Z

No, the time at which I undelete the answer is unrelated to whether or when the question gets deleted

But if you want to save the answer for a more acceptable question (whatever that means), please do. That's the whole reason we do this: to discourage people from answering homework questions.

Well, not the whole reason, but one of the reasons

I guess the main reason is really to keep people from asking homework questions

glance

9:42 AM

yes, I got that, however please try to follow me in this reasoning: suppose I know that a question with no answers (and eventually other conditions) gets deleted after, say, two weeks. Now I "temporarily" delete an answer to that question for three weeks. Is the deletion of that answer temporary? You see why your answer "the deletion of the answer is temporary, what happens to the main question is another issue" isn't that good?

please understand that I'm not trying to argue with you, and I believe you if you say that this was not intentional. But maybe in the future a warning that this can happen would be nice

David Z

Well, if you consider a non-deleted answer to a deleted question to be deleted, then by that reasoning the deletion is permanent.

glance

saving it didn't seem necessary because you said that the deletion was temporary. If I knew it would have been eventually deleted I would have saved it

@DavidZ isn't that so? I mean: can I still access that answer?

David Z

I'm not sure, actually.

Q: Lost my answer on deleted question

Note; I have read Show all of my question/answers to me even if they are deleted but I didn't see an answer to my question. A couple of days ago, I answered a question for a new user, and I worked on my answer for about 40 minutes. The question didn't receive any downvotes, and wasn't marked as...

support deleted-questions

glance

the link I gave you is supposedly of my answer, given that I got it from the rep-changes bar

David Z

According to that, it seems that you can't see the answer, but I can copy the source markup for you if you like

glance

9:47 AM

I see, this is good

as another thing I could ask you if the automatically deleted question in question (no pun indented) really deserves the deletion

I believe the "don't want to help students posting it cheat" argument is expired, isn't it?

David Z

That's not the reason the question was deleted though.

glance

then what is this reason?

David Z

The question was deleted because of its score and age, and the fact that it was closed, I assume.

And in turn, the reason that the algorithm which automatically deletes such questions exists is that those questions presumably do not add value to the site.

If you think that question didn't deserve to be deleted, you can make an argument on meta that either the algorithm should be changed, or that the question adds enough value to the site that the algorithm should be overruled.

(I suppose you can guess that I do not believe either of those things is the case.)

glance

I could argue that the question being closed with no answer certainly doesn't help in its popularity, but I can see your argument and I'm ok with it.

David Z

Fair enough

So before I leave, did you want the text of your answer?

glance

9:53 AM

Could you now please send me the deleted answer's source?

I guess doing it in chat isn't the best option though

David Z

Yeah I can put it on pastebin if that's okay

glance

yes thank you

David Z

here you go

(I set it to expire in a month)

I guess I would also say, keep in mind for the future that if you post a complete answer to a homework-like question, you can't count on having access to it later on if you don't save it yourself

@DavidZ yes I got that message :)

Also, r<0.12 @ 95%; median r=0.075; mode r=0.05; r>0 @ 92% (not statistically significant as they themselves admit)

user54412

On that note, it gives me a warm fuzzy feeling to be in a field of science where a p-value of 0.08 is not taken to be a detection of something.

user54412

It's also worth noting that the B-mode signal is definitely there, and in fact the joint analysis finds a 7-sigma detection of lensing. It's just a question of what part of the remaining signal is dust vs. tensor perturbations.

@ChrisWhite Does the detection of B-mode polarisation constitute a detection of gravitational waves?

I can never get over the "(+216 authors not shown)" in experimental physics papers

Yeah, mega collaborations like that BICEP/Planck/Keck paper are pretty crazy

tpg2114

@KyleKanos Get out of my head

Kyle Kanos

The nozzle question?

tpg2114

Yeah

Kyle Kanos

That's awesome that I guessed it

tpg2114

I flagged it as too broad. There are literally dozens of books on compressible, reacting Navier-Stokes

OP does kinda ask for references, so if we added that tag it could be an okay question

tpg2114

@KyleKanos So either you read my mind, or you learned my patterns and predicted...

Kyle Kanos

@tpg2114 Isn't that the same thing?

tpg2114

True. And you could remove the greeting and thanks while you edit the tag in

Time for class... boo

Be back later

Kyle Kanos

Hmm, my university's cluster IT team is emailing the listserv again claiming that the /scratch directory is 97% full. I suppose I ought to at least check, no?

Does anyone know why we don't have a tag for the Boltzmann distribution? According to this search, it's mentioned in 300+ posts.

(100 of which are questions)

Is it because we'd want one for the other distribution functions? And that one for each is too much?

ACuriousMind

@KyleKanos Do you think adding boltzmann-distribution adds anything over just tagging it with statistical-mechanics`or thermodynamics?

Kyle Kanos

Maybe in some cases

If the question is more about the distribution function itself, then I could see the stat-mech & thermo tags being unnecessary

ACuriousMind

@KyleKanos But is it physics if it is only about the distribution function?

Kyle Kanos

Possibly, but probably more often than not , no

It was editing this question that got me thinking about it:

Q: Chemical Potential, Boltzmann

The electrochemical potential of an ion i in an electrolytic solvent is given by: \begin{align}\mu_i(\vec r) &= \mu_i^0 + RT \ln(a_i(\vec r))\\& = \mu_i^0 + RT \ln(\gamma_i(\vec r) c_i(\vec r)/c_0) \\&= \mu_i^0 + RT \ln(c_i(\vec r)/c_0) + RT \ln(\gamma_i(\vec r)) \\&= \mu_i^0 + RT \ln(c_i(\vec ...
