hmm, rather quiet today.
01:45
@rob hello, how are you?
I'd like to make a few observations about learning software:
1. BlackBoard sucks.
2. Pearson's Mastering sucks.
3. Web 'applications' that hijack my browser behavior suck even more.
4. These piece of junk tools respond like it's 1992 and they're written in Java. Which sucks.
Does someone know the answer to this question? physics.stackexchange.com/questions/305369/…

Q: Why work done in irreversible adiabatic expansion greater than reversible adiabatic expansion?

anonymous During expansion, work done in reversible processes is always said to be greater than irreversible processes (according to my textbook). However, in the graph above we can see the the area under the PV curve of the irreversible adiabatic expansion is greater than the area below the PV curve of...

what do you want in online learning software @dmckee? (just curious)
@heather I'm teaching online again this semester. And in the summer.
oh, i mean what features do you want of the software =)
01:49
I don't want anything with it. I want to tell these numbskull webmonkeys to take a flying leap.
But I get to use it anyway.
whoa
get = forced i assume?
Well, if I want a paycheck.
Seriously, the single bigest problem with them (besides hijacking my browser's behavior which is beyond the pale), is response time.
Every single action you can take in these tools precipitates a 10+ second page load. Even on a fast network on a fast and lightly loaded machine.
That's more that time enough to lose your train of thought and, because I spend around 10 second on average on a page, it means that it doubles how long it take to get anything done.
Un-fscking-acceptable.
@anonymous Dude! You posted that less than half an hour ago. It's still on the front page.
@dmckee Have you considered simply recording your classes in form of videos and distributing it among students and later clarifying their confusions by chat or mail ? I find that method quite effective and I have seen many teachers use it.
@dmckee I just wanted to check if anyone on hbar knew the answer...
@anonymous It is, in my experience and according the pedagogical literature almost the worst way (on average) to teach.
Yes, there are a small group of students who love it. But they will learn no matter what you do.
It's how the other 90% react that matters.
@dmckee I don't know. Maybe. But our teachers give us a time limit to watch the video like say 1 or 2 days. The next day we are told to collect all our queries and get them clarified. Then after a chapter is over we are sent online time bound tests.
But, maybe your situation is different so I can't say much...
02:00
@anonymous The one time I took an online course, that exactly what the professor did. It worked great for me, because I was already a self-learner.
@dmckee that is infuriating. i am so, so sorry.
i am a impatient person, and the internet has made me even more so.
i don't want to wait ten full seconds for the darn page to load =P
But in most classes, a large fraction of the student can't focus on the material the way that kind of presentation demands. And I hate recording material to a lack of audience. The way the room reacts helps me tune my presentation.
@heather The long lags remind me of programming in the 80s and 90s. I learned how to deal with that and can call upon those skills. But it seems so unnecessary.
i kind of want to smack my teacher, which is annoying, because i actually like my teacher. but this project, ergh.
@dmckee agreed
@dmckee yeah, it just seems like that sort of thing shouldn't be a problem anymore.
02:03
I'm sure there is a lot of data-base integrity stuff going on behind the scenes, and that stuff takes time, but if the product won't actually work as a remote service, then it has to be local.
too bad you don't have a server under your staircase like John Rennie =P
well, I don't actually know if that would help. but whatever. =)
To be fair some of these services probably were written in 1992-era Java. (Noting that Java was invented in 1991 and not released to the public until 1995)
I was hopeful earlier this year when the Distance Learning office was making "the BalckBoard upgrade we need it to expensive" noises.
I was hoping for a local Moodle.
@DavidZ i always forget on the timescales with these things. part of me thinks python's been around forever and another part thinks my parents grew up in the stone age.
Yeah, it's hard to put a perspective on moderately ancient history
02:05
But some sales-type gave them enough of a break to keep them on-board and now our soul is in hock for another five years. ::sigh::
BTW is anyone else seeing my avatar as a Gravatar identicon (green geometric design), rather than my usual hat portrait? Or is that just me?
@DavidZ Just you it seems :)
@DavidZ well, in the slot to the right where present users are listed i see a green geometric design it marks as you. to the left where you talk, i see a hat portrait.
weird.
02:07
@DavidZ I think @ACuriousMind asked the same thing earlier. About your user icon.
@heather Huh it's the other way around for me.
@dmckee Yeah, I had heard that Gravatar has been behaving oddly, but it seems to be getting worse and worse.
I can see David's image in both places
No green avatar
I've only recently started experiencing the problem with my own avatar myself
Here's another test: what do you see at this URL? gravatar.com/avatar/…
i'm trying to work up the courage to continue typing up this LaTeX document. ::sighs::
@heather courage?
02:08
@DavidZ There I see a green avatar
@DavidZ i have to create a couple of diagrams.
I've heard many things about LaTeX but "courage" is atypical
well, it's not actually the LaTeX.
it's two things:
1. creating a diagram in google drawings
actually, multiple, but whatever
@heather Writing diagrams in latex (with tikz or something) is cool, but not always worth it. If you can do them well in something else that's usually the better part of valor.
and 2. this project is just rather annoying and i have a deadline on it and it's just bleh.
02:10
@anonymous That's what makes it so odd. It seems that different people are actually getting different URLs for the avatars, rather than just one URL resolving to different images depending on who views it.
@dmckee i'm doing them in google drawings. which is better, but still bad.
if i was doing them in tikz, i think i'd be on my deathbed right now.
(sorry, i'm feeling melodramatic.)
@heather I'd say try Inkscape. Though if you wanted to learn TikZ, this is a prime opportunity to do it. Sometimes learning something new spices up your project enough to help you push through it.
Speaking of which I have some projects I should get back to.
@DavidZ whoa...you're hat portrait where you talk just switched to the geometrical thing.
::blinks::
Probably because of the size change
and now it's back to the hat
02:12
For me it was precisely the other way around. I see the green thing when it's small and the hat portrait when it's large.
And I've got them all with the groovy hat.
@DavidZ what size change?
@heather Notice that the avatar where you see the green thing is bigger than the ones where you see the hat, because the former is next to three lines of text while the others are next to only one or two lines
I guess it depends on your screen size actually
oh, okay
makes sense...once you posted the third line just now it switched again.
e.g. <-- hat
<-- hat
<--- green thing
if that made any sense. lol
@heather Maybe you could help out potential troubleshooting: right-click on the two versions of my avatar (the small one and the big one) and choose "copy image location" or equivalent, and let me know what URLs you get
02:16
okay, one moment
gravatar.com/avatar/… - green one (big)
gravatar.com/avatar/… - hat one (small)
Thanks @heather and @anonymous
not a problem
@heather I find this to be the hat one too :P
Both of your images appear as the hat one
02:18
weird.
i find the first one to be green
Hm... I wonder if it's an HTTPS thing?
partially, at least
@anonymous this appears to be the green one to me
both of your images appear as the green one.
Hahahaha XD
No idea :P
Hi @Kaumudi.H
Oh that's interesting, @heather for you the big image has s=32 and the small one has s=16 whereas for me the big one has s=64 and the small one has s=32
I wonder if you go here do you see the hat
yes i see the hat
02:23
@DavidZ yes
@Kaumudi.H, hello =)
Man, Gravatar is messed up
behold, my hideous masterpiece in google drawing:
Anyway I changed from Gravatar to storing my profile picture on SE Imgur so hopefully there will be no more of this weirdness once the cache refreshes
@heather hehe
@DavidZ sounds good.
02:24
I'm guessing... something about fields?
@DavidZ yeah. it's supposed to be a grassy field that has the variable of height ($\phi$) and is bumpy and stuff and then we describe position of the person using the x-y coordinates. then you get into change in height over change in distance stuff.
the stick figure is really a nice touch, I thought. =P
Er, someone flagged like all the (fun) "Best Of" Meta questions to be closed as POB
POB - ?
primarily opinion based
ah, I see.
02:31
It's a totally standard acronym I've been using for a while
@heather So
My friend was looking for a geophysics stack exchange
and we found the earth sciences one
@KyleKanos :-/
@BernardoMeurer Debatable that you have a "friend" :D
and I had mentioned you to her previously, and I saw some question you made on their chat back in november about tectonic plates
so now she's making an SE account
to tell you about tectonic plates
seriously?
wow.
02:33
@KyleKanos Why you do this
@heather Yes.
@BernardoMeurer Habits. Terrible, awful habits
I sometimes feel bad.
Then I remember it's the internets and no one cares
I care about you :(
You're like the Noah's Ark of children
Not sure that reference is valid
how do I put a line through text? <strike></strike> doesn't seem to be working
@heather in chat? ---text--- IIRC
02:35
---text---
@KyleKanos it only would be if you had two of every kind
@DavidZ no, in comments
@KyleKanos Have another boy
@heather I don't think you can
<s>styrike</s>
(in comments that is)
hmm
^cool!
02:35
Why do you want to strikethrough text in comments anyway?
@DavidZ She's edgy af
^uh...no.
@BernardoMeurer I'm ignoring that
@BernardoMeurer I'd like one
@DavidZ I don't really need too.
02:36
Buuut we'll see
just curious.
Yeah, I've never come across a case where it was really necessary to use strikethrough text on SE, as far as I can remember
@heather She needs to get rep. What should she ask?
@DavidZ What? It's true, heather burns me more than most other members here :P
@BernardoMeurer answering also doesn't require any rep
@DavidZ Shes a geophysics major with no physics currently. I don't think there's a lot she could answer.
02:38
@BernardoMeurer I actually have to go soon anyway =/
@heather WAIT
@BernardoMeurer she could answer on earth science, chat is SE wide
10 rep anywhere you can chat anywhere.
no, scratch that.
20 rep?
@BernardoMeurer You need no rep to chat. Just create accounts on any 20 SE sites.
There are like 200 SE sites
She's asking about the differences between temperature kinetic energy and heat I think
02:39
Sign up on any 20 of them = chat access
@anonymous Lol, hax
1 rep from each site :)
@heather yep, 20 rep. Signing up on 20 of them would get you there.
That is bug on SE.
02:40
I could grant her access to this room temporarily
@anonymous That's been mentioned before, IIRC
Now she's riled up about asking the question lol
26
Q: I was able to post in chat with less than 20 rep

LamartI joined 20 other sites (out of the many) and even with 1 rep was able to post in any of the chatrooms. For example: In ELL, I have just 1 rep and have posted messages in its chat. ell.stackexchange.com/users/18923/lamart This seems like a bug because I should have needed 20 rep to post. ...

::shakes head::
that's hilarious

A: Best of PSE 2016 - Q&A rookie of the year

Numrokheather: For exceptional research effort in her answers and making the site more open to new users from all levels. And ~4500 reputation in the first 7 months says a lot, too...

^eesh
noticed that a minute ago

Q: Kinetic energy, heat, and temperature

user142175What is the best way to explain the differences between heat, kinetic energy, and temperature?

02:44
Well, you are the obvious candidate for that one
@KyleKanos Please edit
@DavidZ not really
@heather who else?
i mean, there are other people, i saw some search somewhere
@BernardoMeurer What do you mean?
02:45
one moment, let me find it.
@KyleKanos Edit her question lol
Oh
Er, it looks POB to me
@heather "there are other people" hardly seems like a counter-argument :-P
02:45
I'm 9th on that list
16 mins ago, by Kyle Kanos
primarily opinion based
@BernardoMeurer primarily opinion based
Upvote for the sake of it, all she needs is the chat rights
@heather Oh, I see what you mean. Still there's more going into this determination than just reputation.
Farcher - member for 11 months, 20k rep
nuts.
02:47
@BernardoMeurer is that your friend who just wants to access chat?
@heather do you know the stories of Jon Skeet?
a few
Jon Skeet is a legend
where's that meta post
366
Q: Jon Skeet Facts

Bill the LizardI'm looking for Chuck Norris Facts style answers. In case anyone is curious, this question was inspired by Jon's own comment to this question. EDIT: If you're into cryptography, you may enjoy these facts. Now with official sanction from the powers that be!

^here we go
02:48
@DavidZ Could you give her chat permissions?
trying something... @KristinaLevine
ok @KristinaLevine you should be able to post here now, if I did it right
Hey @heather! And thank you very much @DavidZ
@KristinaLevine, hello
welcome to the h bar =)
I hear you would like to know about tectonic plates? @heather
@KristinaLevine Welcome to the h-barbecue :D
02:51
Thanks :)
@KristinaLevine no problem. We don't usually do this but Bernardo vouched for you
@KristinaLevine Now don't embarrass me
@DavidZ <3
@KyleKanos I do have friends, see
Many thanks to @BernardoMeurer
3
@KristinaLevine, thank you, yes - I'm in 8th grade earth science and the teacher was talking about tectonic plates, and i was wondering about how you could predict future movements of the tectonic plates.
@BernardoMeurer Probably sockpuppet
02:54
@KyleKanos Impossible, I would never know about tectonic plates
Does not involve computers
BTW @Kristina I hope you'll stick around and ask or answer some questions - if not on the Physics site, anywhere on the SE network.
@KristinaLevine It's 100% a trap
@DavidZ is basically Darth Vader
@BernardoMeurer Yeah, who really knows your knowledge
@BernardoMeurer, who's Darth Sidious then?
@heather You
Only Sidious would ask this question
to pretend it isn't him
I bet you're actually Jon Skeet
02:57
@BernardoMeurer, wait, wait: I break programs. Programs compile when Jon Skeet is within a mile of them.
@heather Maybe you're pretending
"Oh Bernardo please help me my Python code is exploding I don't know what to do"
It's the internet, everyone is pretending something
While in fact you are hacking the FBI in the back
@BernardoMeurer i was about to say "you think I'd drive you nuts pretending" (remembering the color fiasco) and then I realized that's exactly what Darth Sidious would do.
02:59
@BernardoMeurer exploding is an understatement, for my Python code =P
@BernardoMeurer exactly
