Hi all. Awaiz from Aurangabad, india
I chose to use git via terminal and when posting my first commit... git comes up with a "Tell me about yourself" error. Learnt the hard way that git was installed but not yet completely configured.
Although the solution can be found easily by running a search, I am writing my adventures none the less.
Lorena A. Barba
@labarba
Did we forget to say how to config git with your name and email on the tutorial?
Awaiz Muakdam
@awaizmukadam
uh I think I might have skipped it the other day..
Let me check once again.
oops
i found my error apologies
Lorena A. Barba
@labarba
I'm actually looking for it and can't find it … where do we say it? (if at all)
Awaiz Muakdam
@awaizmukadam
I was trying to commit using a different email id...
Lorena A. Barba
@labarba
Ah! That'll do it.
Awaiz Muakdam
@awaizmukadam
"Installing git on Linux" has the steps written clearly Lorena..
Lorena A. Barba
@labarba
Ah there it is. I was looking for it in the last unit, playfully titled "Terminal time"
Awaiz Muakdam
@awaizmukadam
In my fault, I had setup GitHub way back during AeroPython... and installed git (local) just last week so I didn't quite supply the right email id during $ git config --global user.email
I was also in "Terminal Time"
might I suggest you add the config part again in "Terminal Time" because the "Tell me about youurself" error won't throw before anyone pushes the changes.. ?
Lorena A. Barba
@labarba
OK, good suggestion. We can add a note and a link back to previous unit.
Awaiz Muakdam
@awaizmukadam
great... thanks Lorena

I should probably update README.md too.
Lorena A. Barba

OK, we'll have a look!

Phugoid notebook - small issue - the disccusion refers to numbered equations (eg 10, 15) - but none of the equations in the notebook are numbered.
Lorena A. Barba
@labarba
The numbers sometimes don't show up … but they should. We enabled them with some javascript in the notebook style, and some browsers don't show them. Do you not see them when opening on nbviewer or locally?
Chris Short
@ChristopherShort
Perhaps I spoke a little early: loading the notebook's style sheet is in the last cell, and does number the equations - but not completely. Reloading the notebook (or restarting the kernel) does number all equations except the first ones for lift and drag - and so numbering in the discussion appears to be out by 2 (eg what I believe are equations (15) and (16) and labelled (13) and (14) in my local notebook.
Lorena A. Barba
@labarba
Yes, it looks like the equation numbers appear correctly on the nbviewer version, but locally, each time you execute the markdown, it increases the numbers by one.
Chris Short
@ChristopherShort
And looking at the nbviewer version, none of the maths is being rendered at all for me - the mathjax(?) is left raw. I'm on Safari/Mac OX if it matters...but don't think I've seen this as a problem before.
Yes - if you repeatedly run the stylesheet - it increments equation numbers but, for me, fails to label first two equations always.
Lorena A. Barba
@labarba
The fact is, equation numbers are not supported in the IPython Notebook. We decided to hack it with javascript in the style sheet
The other problem of MathJax rendering, yes, it sometimes happens and I don't know why. Cache stuff?
Lorena A. Barba
@labarba
Can you try opening the nbviewer on a new browser window in "private" mode (will not have any history)
FredInChina
@ReblochonMasque
I've always found it was a rather bad idea to "hack" the framework... I'd very much rather work with the plain vanilla notebook rather than see everything break the moment there is a small update. :)
Lorena A. Barba
@labarba
We had a colleague read over the notebooks for friendly review and they insisted on having equation numbers. So we researched and found a way to add them.
FredInChina
@ReblochonMasque
Yes, last sec requirements & changes of scope... I know... LOL
No worries, at some moment it'll work
Lorena A. Barba
@labarba
The issue of MathJax not rendering is something that I can't figure out.
Chris Short
@ChristopherShort
yes - private browsing labelled ALL equations correctly and rendered MathJax! Interesting (in a sad way)
FredInChina
@ReblochonMasque
Yes, that happens too... it has always been temporary for me & I've blamed it on either the network or my VPN, but maybe there is another issue.
Usually, reloading the notebook solves it. I stopped using safari for many small blips like this.
Lorena A. Barba
@labarba
YIkes! We're on to something, ChristopherShort

@ReblochonMasque
I am using chrome exclusively for the notebooks now - Firefox seems to leak memory with notebook.
Lorena A. Barba
@labarba
I thought Firefox leaked memory with anything.
FredInChina
@ReblochonMasque
hehehe, maybe :)
BTW, all the posts I made on the forum last night (8 hours ago are gone...
it doesn't work as I thought after all.
Lorena A. Barba
@labarba
Wow. Discussion page is totally buggy.
Nothing to do for the moment. Devs said they'd build a new instance of Open edX from scratch an migrate the course
The edX guys push to their repo willy-nilly, I'm afraid.
FredInChina
@ReblochonMasque
That doesn't sound too good...
I am sorry to hear all the problems you have to deal with
on top of a first offering of the course (
Lorena A. Barba
@labarba
No. That's why there aren't other universities in the US —except for Stanford— launching their own instances. What we did is totally crazy.
