The best place to start with any open source contribution is with something that fits your knowledge, experience, and area of interest.
Before you begin
Before you start contributing, it can help to get a feel for the project as a whole. If you haven't already done the BeeWare Tutorial, start there. This will give you exposure to the most important BeeWare tools, so you can see how they all fit together.
Once you've completed that tutorial, you'll be ready to pick something to work on. If you had any problems doing the tutorial - if you hit a bug, or if the language used to describe a step wasn't clear - that's a great place to start! If you can turn your experience into an improvement in the tutorial, the next person who does the turorial won't hit the same problem.
However, if your tutorial experience was completely smooth (and we hope it was!), here are some ideas for where to get involved, depending on your skills and interests.
Python programming
Briefcase
If you'd like to contribute to a tool that has a clearly defined problem statement, but needs bugs squashed and features added, Briefcase may be the project for you. Briefcase is a tool for packaging a Python project as a standalone GUI application. It takes a pyproject.toml configuration file, and uses that configuration data to generate installers or distributable application bundles.
The Briefcase issue tracker has a collection of feature suggestions (and a smaller number of bugs). If this is your first time contributing, look for one of the tickets labelled first-timers-only - these are issues that have been specifically picked for first time contributors because they should be relatively straightforward to implement. You may also find it helpful to filter the tickets for the platform you actually use for development - it will be difficult to fix a Linux bug if you don't have a Linux machine to use for testing!
Pick a ticket, leave a comment that you're looking into the problem, and try to develop a pull request implementing a fix!
Colosseum
If you like the idea of a very well specified, but complex problem, Colosseum is a good place to contribute. Colosseum is a pure-Python, browser implementation of the CSS layout algorithm. BeeWare uses it to lay out widgets on the screen of an application. The CSS specification has an extensive test suite; Colosseum needs to pass all those tests.
The Colosseum documentation has a contribution guide to walk you through your first Colosseum contribution.
GUI programming
If you've got experience with a native widget library - Cocoa on macOS, GTK+ on Linux, Windows Forms, or the native iOS or Android libraries, you may be able to help with Toga. Toga is a cross platform widget toolkit - it provides a common interface for user interface elements like buttons and trees.
Toga has a range of interfaces already defined; however, the implementation of those interfaces isn't complete across all platforms. Pick a widget, and implement that widget for your platform of choice!
Even if you don't know a native widget library, you may still be able to help with Toga. Writing new widgets is a lot less complicated than it may seem. Every platform has documentation for how to use their native APIs, and the process of translating that platform documentation from another langauge (e.g., Objective C or C#) is a relatively straightforward process. The existing code should give you some pointers of how this can be done, and the BeeWare team is happy to help if you need it. Jump on the BeeWare Gitter channel and we'll do whatever we can to help!
If you're not up for transforming code from one language to another - there's alwasy the test suite. Toga's core library also has a test suite, but the coverage of that test suite isn't very good. Pick a widget interface, and see if you can write a test for it!
Documentation
Good documentation is essential for any successful project. We know that Toga and Briefcase both need significant improvements to their documentation. You've done the tutorial; now take a look at the documentation for Toga and Briefcase and see if you can find a way to improve the tutorials, references and topics guides that are there.
Tutorials
One of the best ways to contribute is to make sure our introductory and tutorial documentation is rock solid. Pick a project of interest from the BeeWare suite, and try to follow the getting started guide and tutorial. If you can't find the getting started guide - then that's the first thing to report!
As you work through the tutorial, take note of anything that doesn't make sense, or doesn't work. Then open a bug report for those problems.
Windows
If you're a Windows user, BeeWare can definitely use your help. The core team all use Linux and macOS in their daily development, and as a result, it's really easy for Windows incompatibilities to slip in. This is almost always due to an oversight. Identifying - and maybe even fixing - problems with running BeeWare tools on Windows is an immense help.
Languages
Do you speak a language other than English? At present, the core team are all native speakers of English. Providing translations of documentation, or completely new tutorials or guides in your native language is a great way to contribute. Pick a project that already has documentation and translate that text. Alternatively, start from scratch and write a completely new tutorial.
If you speak a language with a non-latin character set (e.g., Russian or Chinese), or a language with a right-to-left script (e.g., Hebrew or Arabic) you'll be able to point out all the places where we've assumed simple ASCII encoding or left-to-right conventions. Pick any of the active BeeWare projects, and try to use it with using your native language. If you hit any problems, report those problems as bugs; if you are feeling particularly adventurous, see if you can work out how to fix the bug, too.
Practical usage
One of the best ways for us to determine where our gaps are - in both documentation and APIs - is for people to actually use BeeWare to build something. So, if none of the ideas so far sound interesting, why not try something of your own? Use the BeeWare suite to build that app you've always wanted - a desktop visualization of a data source, or a mobile application to track your activities - whatever it is, try to build it.
We can almost guarantee that you'll hit problems. BeeWare is a still a very young project. But the problems you hit will give us a great indication of what needs to be tackled. It will indicate what widgets we need, and what documentation needs to be improved. So, as you hit problems building your own app, log issues with the BeeWare projects that caused problems. This will enable us to identify what we need to improve - and, it might even be a source of inspiration for you to contribute!


Hi! I'm Wendy Hines. I am an assistant professor of mathematics at UNL. I began
here in Fall 1993. Before that, I received my PhD from Georgia Tech.
Research
My research is in the area of dynamical systems. Currently I am working on
discretized delay equations and continuity of attractors and Morse sets with
respect to the disctretization timestep. This work is in my paper with Tomas
Gedeon entitled Continuity of Morse Sets With Respect to the Discretization
Parameter.
Summer Camp
This summer I am teaching a summer math camp for high school girls.
I'm teaching a course on Iterations of Functions. Soon we will be doing
stairstep diagrams to graphically show the orbit of an iterated function.
Here's an example.
We will also be doing bifurcation diagrams. Here's the bifurcation diagram for
the logistic equation.
You can find the notes for this in Iterations.
It's a great experience! It is not very often that a teacher gets to teach 14 students who really
want to learn!

A pure Python implementation of geodesy tools for various ellipsoidal and spherical earth models using precision trigonometric, vector-based and approximate methods for geodetic (lat-/longitude) and geocentric cartesian (x/y/z) coordinates.
Transcribed from JavaScript originals by Chris Veness (C) 2005-2016 and published under the same MIT License**.
There are two modules for ellipsoidal earth models, ellipsoidalVincenty and -Nvector and two for spherical ones, sphericalTrigonometry and -Nvector. Each module provides a LatLon class with methods and functions to compute distance, initial and final bearing, intermediate and nearest points, area, perimeter, conversions and unrolling, among other things. For more information and further details see the documentation, the descriptions of Latitude/Longitude, Vincenty and Vector-based geodesy and the original JavaScript source or docs.
Also included are modules for conversions to and from UTM (Universal Transverse Mercator) and Web Mercator (Pseudo-Mercator) coordinates, MGRS (NATO Military Grid Reference System) and OSGR (British Ordinance Survery Grid Reference) grid references and a module for encoding and decoding Geohashes.
Two other modules provide Lambert conformal conic projections and positions (from John P. Snyder, "Map Projections -- A Working Manual", 1987, pp 107-109) and several functions to simplify or linearize a path of LatLon points (or a NumPy array), including implementations of the Ramer-Douglas-Peucker, the Visvalingam-Whyatt and the Reumann-Witkam algorithms and modified versions of the former.
All Python source code has been statically checked with PyChecker, PyFlakes, PyCodeStyle (formerly Pep8) and McCabe using Python 2.7.15 and with Flake8 using Python 3.7.0, both in 64-bit on macOS 10.13.6 High Sierra.
The tests have been run in 64-bit with PyPy-Python 2.7.13, Python 2.7.15 (with geographiclib 1.49 and numpy 1.14.0), Intel-Python 3.5.3 (and numpy 1.11.3) and Python 3.7.0, all on macOS 10.13.6 High Sierra and with Pythonista 3.2 Python 2.7.12 and 3.6.1 (both with numpy 1.8.0) on iOS 11.4.1.
Previously, the tests were run with 64-bit Python 2.6.9 (and numpy 1.6.2), 2.7.10 (and numpy 1.8.0rc1), 2.7.13, 2.7.14 (and numpy 1.13.1), 3.5.3, 3.6.2, 3.6.3, 3.6.4 and 3.6.5 on MacOS X 10.10 Yosemite, MacOS X 10.11 El Capitan, macOS 10.12 Sierra, macOS 10.13.4 and/or 10.13.5 High Sierra, with Pythonista 3.1 on iOS 10.3.3, 11.0.3, 11.1.2 and 11.3, with 32-bit Python 2.6.6 on Windows XP SP3, with 32-bit Python 2.7.14 on Windows 10 Pro and with 64-bit Python 3.7.0 on Debian GNU/Linux 9.
In addition to the PyGeodesy package, the distribution files contain the
tests, the test results and the complete documentation (generated by Epydoc using
command line: epydoc --html --no-private --no-source
--name=PyGeodesy --url=... -v pygeodesy
).
To install PyGeodesy, type pip install PyGeodesy
or
easy_install PyGeodesy
in a terminal or command window.
Alternatively, download PyGeodesy-
from PyPI or
GitHub,
unzip
the downloaded file, cd
to directory
Pygeodesy-
and type python setup.py install
.
To run all PyGeodesy tests, type python setup.py test
before
installation.
Installation of NumPy and GeographicLib is optional, but the latter is required for two ellipsoidalVincenty functions, areaOf and perimeterOf.
Some function and method names differ from the JavaScript version. In such cases documentation tag JS name: shows the original JavaScript name.

GetStatusChange(UInt32, AbstractReaderState[])
The GetStatusChange(UInt32, AbstractReaderState[]) function blocks execution until the current availability of the cards in a specific set of readers changes.
The caller supplies a list of readers to be monitored by a AbstractReaderState array and the maximum amount of time (in milliseconds)
that it is willing to wait for an action to occur on one of the listed readers.
Note that GetStatusChange(UInt32, AbstractReaderState[]) uses the user-supplied value in the currentState members of the readerStates
AbstractReaderState array
as the definition of the current state of the readers.
The function returns when there is a change in availability, having filled in the EventState members of readerStates
appropriately.
Declaration
ErrorCode GetStatusChange(uint timeout, AbstractReaderState[] readerStates)
Parameters
| Type | Name | Description |
|---|---|---|
| System.UInt32 | timeout | The maximum amount of time, in milliseconds, to wait for an action. A value of zero causes the function to return immediately. A value of INFINITE causes this function never to time out. |
| AbstractReaderState[] | readerStates | An array of SCARD_READERSTATE structures that specify the readers to watch, and that receives the result. To be notified of the arrival of a new smart card reader, set the szReader member of a SCARD_READERSTATE structure to "\\?PnP?\Notification", and set all of the other members of that structure to zero. Important Each member of each structure in this array must be initialized to zero and then set to specific values as necessary. If this is not done, the function will fail in situations that involve remote card readers. |

Syncing the videos
1. Record a video of the speaker and a screen capture of the slides at the same time. IN the examples below, I simply used my cell phone to record my video, and I used QuickTime on my Mac for the screen recording.
2. Upload these videos to Cloudinary. NOTE: These files are likely very large, you will want to have the maximum upload size increased on your account to do this.
a. If you wish to have captions, upload one of the videos with the appropriate Cloudinary add-on for captions.
3. When you record 2 videos, it is unlikely that they will start precicly at the same time. This means that the speaker will start talking at different timestamps on each video. In order to sync these, there are two tools. The first tool is the
Find Start Time. For ths url, add the parameter ?url={videoUrl} to load one of your videos. You can then press play, and use the forward/backward buttons to find the approximate start of the video (this can be approcimate to +-2-3 seconds). Do this for each video (presenter and presentation) and record the start values.
4. Now that we know the approximate start times of the video, we will want to sync the videos very closely. Use the
Sync Audio page to do this. Append the url with 4 parameters url1, startTime1, url2, startTime2, where the StartTimes are the values in step 3. For example: start1=6&start2=4.2&url1=https://res.cloudinary.com/dougsillars/video/upload/v1589960426/camera.mp4&url2=https://res.cloudinary.com/dougsillars/video/upload/v1589960587/imagecon_video.mov - video 1 will start at time = 6, and video 2 will start at time 4.2.
5. A Page will load with 2 videos, 2 audio wavforms of the video (10 seconds around the start time), and 2 buttons:
6. Our goal is to get the two videos to start at *about* the same time - say within 100ms of each other. In general, if a slide changes 100ms off from the audio track, it does not effect the overall presentation. The videos are set to begin playback at the "start time" found in step 3. In the screenshot above, we can see that the waveforms do not match - indicating that the audio is off. Press play, and both videos start - you can hear the offset. Adjust the values in the input boxes to change the video start times. Then press "reset" to reset the start points and generate 2 new waveforms. Keep iterating until the 2 videos very nearly overlap: both visually with the waveform and aurally by pressuing play. Record your 2 new start times.
7. Generate your completed. Use the Create Video webpage to configure and upload the final video. (this is still under construction and not part of the repo. However, two sample NodeJS files are here that create the final videos. The presentation_test.js creates a 6 second version of the video to test before generating the full talk. If you are happy with those results - continue with the full presentation.js to create the final video. This file also uses the presenter video to create a transcript and VTT file (which will have incorrect timings).
The JSON response from 7 will have the final url of your presentation. For example, here is a simple talk I created on a Dr. Suess book:
https://res.cloudinary.com/dougsillars/video/upload/w_1920/l_ImgCon2020/fl_layer_apply/l_video:fish_preso,so_7.9/g_north_west,x_550,y_180,g_north_west,fl_layer_apply/l_video:presenter,so_11,c_fill,w_400,h_400/g_north_west,x_50,y_400,fl_layer_apply/fish_preso.mp4

-
close
void close(Throwable cause)
Invoked when an exception is thrown byserviceIO()
.This usually indicates the channel has been (or should be) closed. In any case, it allows for this handler to perform any required cleanup.
Typically this method will close the associated channel, which implicitly unregisters the associated
SelectionKey
s. This also causes theserviceIO()
methods of other handlers waiting on the same channel to be invoked due to the ready I/O, where they will then likely throwClosedChannelException
, causing another invocation of this method. Therefore, this method should be idempotent.- Parameters:
cause
- the error that occurred
