CC Fest presentation?

[tabreturn]

It's Processing's 20th anniversary. The foundation is organising a CC Fest, looking for speakers on various Processing-related topics. If you think it's time for py5 to get some more exposure, somebody could pitch a presentation?

This is a great idea. Thank you for suggesting it. Where did you find out about this? What is the submission deadline? Is there more information about this event in August?

I will submit something, but note I've submitted things to past Processing events and have never gotten accepted. I'll do my best to change that this time around.

[tabreturn]

@hx2A -- my proposal has been accepted 😄. Seeing you can't present, I'll touch on py5's other superpowers, maybe show off the mybinder examples.

It would be excellent if #37 is resolved by then. I've got a plugin working for Thonny (on Linux, that should run on Windows with the #37 fix). I was familiarizing myself with the Thonny architecture, so there's plenty room for improvement, but I plan to refine it further.

[hx2A]

@tabreturn fantastic! I'll do what I can to get #37 fixed and a new release out ASAP. I'll aim for Monday or Tuesday of next week.

[hx2A]

@tabreturn I have finished all of the changes I intend to make for the next release:

• 3 character web colors
• fix Running run_sketch.py on Windows #37
• use Processing 4.0b1

If you like you can test this using this branch:

https://github.com/hx2A/py5/tree/0.5a2rc

Which you can install with something like pip install git+https://github.com/hx2A/py5.git@0.5a2rc#egg=py5.

If everything looks good I will do the release on Monday or Tuesday of next week.

If there's anything I can do to help you be more successful on the 22nd, please let me know.

[tabreturn]

Awesome work, @hx2A! I'm loving the 3-digit hex colors. If you manage to release this before CC Fest, that would be fantastic (any Windows Thonny users could install the Thonny plug-in, and I wouldn't have to change anything).

[hx2A]

@tabreturn I'm loving the 3 digit hex colors also. I've been using them all the time since I added the feature.

Everything look good to you on Windows? No problems running static sketches in Thonny?

I changed very little in this release so it is unlikely I am introducing any new problems. I am determined to release this before CC Fest.

Hey people!

I have just tested @tabreturn's thonny-py5mode on a Windows machine and it works wonderfully 🥇

I see no more reason for my tentative thonny-py5runner anymore I think I'll just delete it, I'm glad it inspired Tristan's sprint 😄

On other news, I have sent a talk proposal for the Brazilian Pycon (it is called Python Brasil because journalists used to think the language was called Pycon...) and if it is selected I think I'll be able to show off some py5 😆

[hx2A]

@villares Great! Did you test with the py5 release candidate from github or did you install py5 from the pypi repository?

Awesome, I hope your proposal gets accepted!

[villares]

I assume it was the one from pypi. I can't remember installing it (maybe Tristan's plug-in did it, maybe I did it last week, it's not my personal computer), Thonny tells me it is 0.5a1.

[hx2A]

There is a big in that version where static mode sketches will not run correctly on windows. The next release will fix that.

Yes, this is for the imported mode (py5 > Run imported mode sketch) that uses run_sketch.py -- which I can confirm is fixed in 0.5a2rc 🥳

Thanks, @villares -- the plug-in gets the job done, but there's definitely room to improve it. I've learned a lot more about Thonny's code-base, and I have some plans to refine and improve things.

[villares]

imported mode seems fine:

[villares]

I have to disclose this is an unconventional Thonny install:
I installed Python 3.9 first on Windows, then pip install thonny. So from terminal I type python -m thonny and I get Thonny 3.3.14

And it uses Python 3.9.6 for everything:

Python 3.9.6 (C:\Users\alexandre.villares\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\python.exe)

[hx2A]

Interesting...you'll have to ask @tabreturn if there is a way to get the release candidate version of py5 into your setup. That is the better version to test with.

[tabreturn]

To summarize this discussion: @tabreturn will present py5 at CC Fest (Processing 20th Anniversary edition) next weekend. The outline for the 60-minute presentation is looking something like this:

1. A very brief overview of Processing's Python history.
2. A brief, high-level overview of how Processing.py works and how py5 is different.
3. The presenter will introduce some py5 basics here using mybinder, contrasting a module mode and py5bot example (attendees might follow along here).
4. Move into Thonny at this point. Attendees might / might not be able to follow along (to wait on everyone to download/install/etc Thonny is impractical and not a good use of presentation time). The idea for this part is to show off py5 as a Processing.py/Python Mode alternative with Python 3 features, using some cool Python 3 libraries (maybe Pymunk).
5. If there is time, some closing Q & A.

The Thonny py5 plugin should work on Windows and Linux by then (see fix #37).

Let me know if there's anything I should change/remove/add.

[hx2A]

Just a thought: maybe some GSoC participation for py5 next round ...

I have no idea how that process works, but if I could get py5 into the summer of docs program, I'd be very grateful.

The proposal is titled "Thonny + py5: A Python 3 Environment for Processing", so I have to be careful not to drift too far off that topic.

Whatever you think is best! Whatever you don't include, I'm happy to have at least provided information that I'm sure will be helpful at a later date. There's a lot of information about py5 that I need to get out of my head and into some form that others can read and benefit from.

I hadn't taken a proper look at convert_image() or even loading images into py5 yet -- this is exciting.

It is particularly valuable for converting SVG images to Py5Images. The Processing library does not support the full SVG specification, so it sometimes doesn't do so well wtih SVG images that it did not create itself. The convert_image() method will use Cairo to rasterize an SVG, and it consistently gives good results.

Another neat thing about convert_image() is the ability to extend its functionality with register_image_conversion(). If there is some graphical image format that someone uses a lot, they can register new functions for convert_image() to use. This will also be an easy way for people to contribute to py5 with PRs.

Also, don't forget about create_image_from_numpy().

@tabreturn Good luck tomorrow! (Or today, depending on your time zone)

I still have that medical thing on Monday but expect to be able to watch part of cc fest tomorrow. If it doesn't make you uncomfortable, I'll probably be in the audience when you are presenting.

[tabreturn]

Thanks, @hx2A! I'm busy working on the presentation now. I hope all goes well with your procedure.

[hx2A]

@tabreturn, that was a great presentation! I even learned some things. I didn't know that you could use a debugger like that to pause a running program. I would have guessed there'd be some kind of timeout if the Java call to Python took too much time to complete.

Here is the link to the JupyterHub setup. I was trying to find it during the presentation but wasn't fast enough:

https://github.com/2i2c-org/peddie-image

They have a JupyterHub setup for their students. To run Processing and therefore py5 on a server like that, you need Java 11 and a display of some kind. The need for a display can be satisfied with Xvfb, a "virtual frame buffer" which is basically a fake monitor. Also, Python 3.8.

Google Colab is on 3.6, but someday they will move to 3.8, and py5 will be runnable there.

What was the other platform the participant was asking about? Code something?

I really like your cheat sheet. That is a great idea. I did note there are a few camelCase issues in the typography and random sections. Also, py5 has a random_int function, which is easier to use than int(random()). You should also mention random_choice, which I use all the time.

Something that I thought of during your presentation is that Processing is going to move to Java 15 in the fall (I believe), and py5 will move with it. How will that affect Thonny plugin users? How does Thonny handle upgrades to libraries anyway? Since people need to use your menu option to download the JDK, there would have to be something to invalidate the downloaded JDK and download another one.

You were up at 4 am for this? You are dedicated!

[tabreturn]

Cheers, @hx2A! It's a pleasure to show off your work.

@mcintyrelabs was the person asking about the Jupyter stuff. Can't recall the other platform he mentioned -- maybe Coding Rooms.

I rushed out the cheat sheet last minute 😅; I've made some corrections now, thanks.

Yeah, the Thonny plug-in is very much a work-in-progress. Will have to look at how I might handle Processing/Java updates.

Good thing I don't have to go into work today ... I'm off to catch up on some sleep.

[sawula]

@tabreturn, i’m sorry i missed it. best way to catch up?

Nice one, @hx2A! I'm submitting something to Pycon (NZ) this week.

[tabreturn]

How about a py5 (and, maybe, Processing-Python) themed Feral File exhibition?

This is an interesting idea. I had not heard of Feral File. As more people start using this and we start building a collection of py5 works, this could be a good way to promote the library and demonstrate that it can be used for artistic purposes.

[hx2A]

Another opportunity to present py5, maybe?

@tabreturn I just submitted my application for this. I'll find out in November sometime.

Thanks again for the suggestion!

@tabreturn Didn't get approved. Oh well, that's life. I'll try again somewhere else!

[tabreturn]

Bummer, @hx2A. Oh well, as you say, there will be other opportunities 🥲
