Description

The usual!

A

Yeah yeah, so that's that's what I was thinking so.

B

Stuart we're talking about are the tutorial the Steve plan, the leading at at the test meeting. But, of course, we want to know what happened with your thingamajig. How did that? Go.

C

Whoa, oh I, think, oh dear oh dear, oh.

D

A

C

Oh my rabbit just society static. The correct thing to do was to viciously attack my broom like it was about to kill it.

E

C

Each other- and he was good, everybody seemed to say good things about it.

C

We covered a cook recovered a lot of stuff in two days. I think everybody walked away with their head hurting a bit, but it's kind of a point, so I put the link to the notes in the chat. Obviously there's a whole git repo that underneath that is.

A

It is drew's the mean Reaper for this yeah.

C

A

Yeah, this is essentially what I was gonna plan on covering, but in an hour instead of today's, because you know we're just more efficient here in the US yeah yeah yeah golly two days, let like.

C

D

A

I was now planning on covering it at all.

C

We did that at the start and then we got him to use it to pull down more notes and stop. As time went on I. Don't.

F

Think you need to do that. I mean this is big challenge. One is honestly introduction to programming.

C

Yeah we started it relatively light on the Python for making sure that everybody knew that what way was up but I think everybody liked most of the people there needed that really and it.

A

I just clicked one over here, the matplotlib dash 101, and there is nothing there is no input or output fields, populated.

A

C

Git repo you're talking about.

A

Yeah, but why isn't are you.

C

A

C

Made multiple versions of each and made multiple versions of each notebook, 141, which is populated and one which wasn't so the people as they were. We were going through it at the front. They were following the they were following doing it in the one which had nothing populating.

A

Mattering eat okay, I see.

C

And then we're like the stuff, that's linked out of the index. Notebook is the populated ones.

A

I, like your example for estimating hi that.

C

Worked really well like that, because that was like what we did at the end of the first session on the second day, so everyone to call caught up to programming python and using matplotlib and, like everyone, had to actually write some code. That did something real and do some relatively interesting, plotting stuff. It took them all about half hour or so, but it seemed to go down really. Well really, people did you know we started off with about 15 on the first day, and then it was a bit less.

C

On the second day guess a few people, both from Sheffield and a couple of people from elsewhere, came mainly for the Python part of it and as opposed to some pie, part, but yeah I think we did relatively walk on people and one.

F

With the new age distribution, the mainly of each first mainly phd's, were.

C

F

Did you install software and people's computers, or did they come with.

C

Or to come with it, pre installed, which, for the most part, worked apart from the fact that some people had version one of I Python, which was incompatible with the notebooks that we'd saved out using version 3. So we had to upgrade everyone's notebooks at one point when, like after the get session, so.

F

Some people were like, oh I've, got paid to know main computer anyway. I can just turn up, and so it wasn't made for the.

C

Most part people had actually most people had some pie and stuff installed properly. It was just a few people had an update version, / the notebook which screwed us over great, mainly because we didn't realize we needed to enforce version to, or else we were just would have said. You need version 2, but we didn't even tell people they needed it because we know did no.

F

Another question: were these people coming from like a zero programming background or an IDL programming language, the people had programming.

C

Experience but just not Python and.

F

C

To teach them programming and some pie in two days.

F

Did and what were the ideals and pay IDL solarsoft that everyone does? Did everyone in the course use that no.

C

We had we had, as I said, we had quite a few people who are more interesting. The Python side with didn't really use some soft, but most of the solar physicist. We had that did obviously right.

A

What most people using anaconda or yes,.

C

We have one person using Caterpie a.

C

Couple of people just using ubuntu packages but yeah most people had anaconda installed. That's what we recommended they installed. You.

E

A

What was the problem with those few people that were running an old version? They just hadn't, updated their anaconda yeah.

C

Basically see I'm.

A

C

Of my signal appears, we had a couple of issues where it wasn't something like we've had one person running an old version of OS x and therefore an old version of safari and I Python 3 uses tornado fear that breaks on an old version of Safari inning to be back with Diggy bugging this person's laptop to work out what the hell was going on, because it was, it would start the notebook fine.

C

It just wouldn't connect to the colonel, because it was the WebSockets implementation that that version of Safari didn't support or just ended up downloading. Installing chrome on this person. That told me here use a real brother.

A

F

A

F

Think most people at the so we'll have a slightly different audience aight, because everyone will be a solid physicist. I would guess- or at least most people like much more likely to be a solid physicist and maybe- and we can assume that everyone has used ssw idea. I don't.

C

Know whether that assumption helps you very much really because I mean, apart from just having a basic knowledge of like solar physics, data problems and programming, there's not a huge amount of crossover. Well.

F

I mean there is asleep, I think the the fact that you have to import, install and then import separate packages, I think that's relatively alien to most solarsoft users.

C

Yeah go: go through namespaces and packaging is definitely important. Drew did a good section in Python 21 namespace. If you did good time.

F

Does it feel, like you know, when people talk people say, oh I want to learn Python. Then it's like well, okay, you can land pay them, but you won't want to do some some. You know something and then you have to you have to get under the whole installation and use of packages. Yeah.

A

Well, I, don't think. Actually, I think the biggest thing, which is something I still kind of get annoyed with, is once you really want to do anything serious. You have to start making your own package making your own package is kind of pain. Well,.

F

Oh, that's, you know, I'm, not sure that you can expect many like people who want to dabble in and son pie, I, listen to make good on packages just yet yeah.

A

F

Immediately, when today's awareness of why why you should switch from ssw a deal to some pipe athan on, why maybe no switch just use take.

B

Advantage of yeah you.

F

Could run to JoVE? Yes,.

B

Another tool for your toolbox exactly yes,.

E

E

B

So you're going to try to distill this into an hour tutorial, Steve well,.

A

I'll probably start with this stuff that I had sure.

B

A

I think Jack weren't, you gonna wear you have you done any work at that I thought you had sort of volunteered to do that. That's.

F

Nice, yes, I have owned tube to do that, I'm going to ecology and toasty semantically.

A

Get crackin then, under.

F

That, under that look, I have to unlock lies myself this week.

F

I have to do a lot of I, do programming, then a good holiday so of, and then I'll come by, can do so by rights. Oh ok, that should talk to you Steven before I'll ever get an idea of what you want to get it. Ok,.

A

Yeah, hey, let's done good look at freely, but I think there's plenty I mean there's playing material here, I think with with what I had put together last time and then with all this here, yeah yeah.

F

A

It's just putting it all together. Well,.

B

It does also raises a question too about whether I'm, because whether it makes sense in any way to have two different levels like I'm worried. You know, one of the problems is that people are going to be coming with such different levels of experience. I.

C

Think if you could get to tutorials doing one on Python them one on somebody's, probably worthwhile, you can go over a lot of just python programming type stuff, which is really important to understand. If you're going to actually appreciate some pie for what it is and then there's obviously just using hot Sun by as well, because I mean just things like lists and lists. Comprehensions make a phenomenal difference to the way you program in python and people coming from IDL. Just have no concept of something like that.

F

Yeah or dictionaries- oh really, miss Dixon reason I'm here for you, I.

C

Used a dictionary comprehension the other day when I was made a multi-wavelength plot for my faces. I just did a dictionary comprehension, which was that, where it automatically made the key the wave length attribute of the mat and the value of the map and I 80 rated over a I, just I just did the dishes a sump I'm at command with a globe in it. So it returned a list and iterated over it and they're not everywhere else. I could just index this dictionary by wavelength. To get a specific map of sniffing specific map.

C

Image of it was beautiful. It's a beautiful little truck dictionary. Comprehend you before I was just like this is amazing. I've I, don't use this all the time. Yeah.

A

And if we are done talking about this, if you didn't have anything else to say it's just we talk about Oh point six. Yes,.

B

We definitely talked about 4.6, what's going on in that store.

C

What's going, all that is Stewart has way too much to do and sweet Jeff all time to do it in and there's one outstanding bug that still needs fixing and when I did try and bundle an RC one a while ago, and it had a very weird packaging error where it wasn't copying across our default config file, which meant you couldn't import. Somebody about exploding I haven't gone back to see whether that bug still exists, whether it was just that computer, I was trying it on or what but basically yeah.

C

This is like one outstanding pull request than one bug fix at least one bug that needs looking into slush fixing, and then we should be.

B

Good to go I when I was skimming over the the Nova for what you did for this session. It didn't look like you were using the 0.6 know.

C

Everyone, okay, didn't happen. I would.

D

Like to got the.

C

M I would like to have got what 1374 into nor point six as well, but I thought all this won't be that difficult and then Negroni everywhere in a fiery born of after pi death, so that I'll have to wait.

F

So I checked. So what are the milestones.

A

So the only thing that's outstanding is 1373 yeah.

C

I just tried that about half a little worried and 1376, which is an issue as opposed to a pull request.

C

mmm 1376 is the only thing: that's stopping the online build passing at the moment.

A

C

I have apps and well I mean I, can kind of see. What's going on there, it does seems to not be finding the file right. I guess that's what's happening, but I don't actually know.

F

Is that a is the website up hello.

F

C

Maybe it's, it might be a dutiful soup parcero. It's not finding the link properly.

C

It's that link link get href is returning. None.

C

Yeah I don't know, but I don't have time to look at that in the next few days. So that's blocking because I want to get the online test building before online build passing before we release they've already found a couple of bugs by going through and fixing all the back cher home and then there's David's fix, which we're concerned won't work on windows.

B

This is 1373 yeah.

C

1373 and its master counterpart need testing on Windows, but we don't run the online tests on that failure because it would just fail all the damn time.

A

Yeah, it's a system, art thing, yeah.

C

It's just an extra tests and it's useful to make sure that it's actually doing what we expect it to.

C

But it's just nice testing on windows. If someone's got a windows, machine, lon, yeah well,.

B

Unfortunately, just transition laptops on a kind of a dead zone and but I can get in a kind of backup today and I can try. It.

A

A

Anybody want to.

A

Anybody wanna volunteer for was it 13 Scott meat? Stick! No wait! Yes, I.

B

Have no experience with this does anyone else, wanna work with the crystal stuff at all, I played.

A

Around with it a little bit when I was ripping out the test files.

B

Jack Randy: do you have more experience.

F

Nope but it doesn't look, I mean it doesn't. Look that bad no.

A

It doesn't look that bad and I've never looked at Callisto I mean.

F

It's not anything newly to do with Callisto data is more to do this.

C

Beautiful asset, someone that needs I, guess someone who's used. Beautiful soup would be the best person to take chances.

F

Yeah, it's beautiful should part of the Anaconda distribution. Yes,.

A

Yeah but it's called as a ps4 ps4. That's.

F

A terrible me yeah.

A

It's so confusing when you're trying to get it you're like kinda, get you know beautiful see, it was like not found, okay, god, damn it from PS for import, cpap well, I have played with beautiful suit, um probably won't be able to get to this today.

C

But I mean I'm not practically going to be out of roller release. This week, I mean probably all um cause I'm moving house tomorrow and then end and tomorrow a.m. wednesday and then I'm flying to denmark on thursday morning from my brother-in-law's wedding. So I want you back till sunday, but next week work yeah I should I should be able to roll with next week. Maybe monday, okay.

A

I mean all I want. Is that it be before the test meeting? Well, it's.

B

Three weeks until the test meeting but I like the dust to settle, so we should trap and try to do it next week, if possible, yeah. It was a week buffer. If.

C

We can roll if we can get it done. If we can get everything working I can roll I'll see one on monday and then we can aim for like final release, not this friday. Next friday.

A

Okay yeah, they say myself to everyone and I was saying You Alber to the other yep I.

B

C

Obviously, if you've got windows, machine lying around or other platforms, I mean I know where we test on the OS X now as well, but like maybe just download it and try and run the full online test suite and make sure everything is behaving properly and make sure the docs build and stuff.

A

B

C

There any PRS we need to discuss I might be out to try and roll release on the plot.

A

A

E

Never responded.

A

To the witch McCoy, everything is ok with having the board meeting I thought.

B

No bunch of people responded, haven't I well.

A

Two people responded to the.

C

Invite we left for the search ain't.

B

Ya, yeah the 13. Oh yes, this time, the 13, yes fun.

C

E

A

That's all I address.

C

If there's nothing else, my job go get home. So it's good level.

A

Yeah that'd be fine with me. Well.

B

Just keep in mind that, on the our current kind of what we're talking about here is we're gonna have a board meeting next week during this meeting. So unless we do something special we're not going to have a developers meeting next week, and so let's just make sure that anything you need store in terms of getting that 0.6 RC out. Let's see if we can get that out by the end of next week, so email or whatever your github yeah yeah yeah great thanks.

B

Stuart no problem thanks.

F

A

Exhibit thanks.
