Brian #1: LEGO Mindstorms Robot Inventor supports Python
- Past
- NXT 2006
- NXT 2.0 2009
- EV3 2013 (plus, weird post apocalypse thing going on)
- Robot Inventor will be available Autumn 2020 (not sure what that means).
- Controllable with both Scratch and Python
- Great updates to help with STEM education
- Instructions for 5 different robots
- interesting:
- 5x5 LED matrix
- 6 input/output ports for connecting a variety of sensors and motors.
- 6 axis gyro/accelerometer
- color sensor
- distance sensor
- and Python!
- Can be programmed with Windows & Mac, of course. But also iOS & Android tablets and phones and even some FireOS devices.
- Related: MicroscoPy - IBM open source, motorized, modular microscope built using LEGO bricks, Arduino, Raspberry Pi and 3D printing.
Michael #2: Step-by-step guide to contributing on GitHub
- by Kevin Markham
- Want to contribute to an open source project? Follow this detailed visual guide to make your first contribution TODAY
- Although there are other guides like it out there, mine is (1) up-to-date with the latest GitHub interface, (2) much more detailed, and (3) highly visual. Includes 16 annotated screenshots + 2 workflow diagrams.
- The only prerequisite is that the reader has a tiny bit of Git knowledge. They don't even have to be a great coder, because what I suggest is that they start by fixing a typo or broken link in the documentation. That way they can focus on learning the contribution workflow!
- Steps:
- choose a project to contribute to
- fork the project
- clone your fork locally
- load your local copy in an editor
- make sure you have an "origin" remote
- add the project repository as the "upstream" remote
- pull the latest changes from upstream into your local repository
- create a new branch
- make changes in your local repository
- commit your changes
- push your changes to your fork
- create the pull request
- review the pull request
- add more commits to your pull request
- discuss the pull request
- delete your branch from your fork
- synchronize your fork with the project repository
- Nice Tips for contributing code section too.
Brian #3: sneklang
- Snek: A Python-inspired Language for Embedded Devices
- An even smaller footprint than MicroPython or CircuitPython
- Can’t wait for Robot Inventor? Snek supports Lego EV3.
- “Snek is a tiny embeddable language targeting processors with only a few kB of flash and ram. … These processors are too small to run MicroPython.”
- Can develop using Mu editor
- Custom Snekboard runs either Snek or CircuitPython.
- Or run Snek on Lego EV3.
- Smaller language than Python, but intended to have all learning of Snek transferable to later development with Python.
- “The goals of the Snek language are:
- Text-based. A text-based language offers a richer environment for people comfortable with using a keyboard. It is more representative of real-world programming than building software using icons and a mouse.
- Forward-looking. Skills developed while learning Snek should be transferable to other development environments.
- Small. This is not just to fit in smaller devices: the Snek language should be small enough to teach in a few hours to people with limited exposure to software.
- Snek is Python-inspired, but it is not Python. It is possible to write Snek programs that run under a full Python system, but most Python programs will not run under Snek.”
Michael #4: Oh sh*t git
- via Andrew Simon, by Julia Evans
- Does cost $10, no affiliations
- This zine explains git fundamentals (what’s a SHA?)
- How to fix a lot of common git mistakes (I committed to the wrong branch!!).
- Fundamentals
- Mistakes and how to fix them
- Merge conflicts
- Committed the wrong file
- Going back in time
Brian #5: Why I don't like SemVer anymore
- Brett Cannon
- Interesting thoughts on SemVer
- SemVer isn't as straightforward as it sounds; we don't all agree on what a major, minor, or micro change really is.
- Is adding a depreciation warning a bug fix? or a major interface break?
- What if projects depending on your project have CI with warnings as errors?
- Your version number represents your branching strategy, so you choose a versioning scheme that's appropriate your branching and release strategy.
- While maintaining multiple branches, x.y.z might make sense:
- x - current release
- x.y - current development
- x.y.z - bug fixes
- x+1 - crazy new stuff
- While maintaining multiple branches, x.y.z might make sense:
- If you aren’t maintaining 3+ branches at all times, that might be overkill
- Maybe x.y is enough
- Maybe just x is enough
- Rely on CI, potentially on a cron job, to detect when a project breaks for you instead of leaving it up to the project to try and make that call based on their interpretation of SemVer; will inevitably disagree
- Remember to pin your dependencies in your apps if you really don't want to have to worry about a dependency breaking you unexpectedly
- Libraries/packages should be setting a floor, and if necessary excluding known buggy versions, but otherwise don't cap the maximum version as you can't predict future compatibility
- SemVer isn't as straightforward as it sounds; we don't all agree on what a major, minor, or micro change really is.
Michael #6: git fame
