Michael #2: You should build an Alexa skill
- Jacqueline Wilson wrote Amazon Alexa Skill Recipe with Python 3.6
- Create a “What’s for dinner” bot
- Amazon calls these utterances:
- “What should I have for dinner?”
- “Do you have a dinner idea?”
- “What’s for dinner?”
- Tie the commands to an AWS Lambda function (returns a JSON response)
- Test via Alexa Skill Testing Tool
Brian #3: RISE
- Reveal IPython Slide Extension
- Making slides with Jupyter notebooks
Michael #4: Closer
- Run, monitor and close remote SSH processes automatically
- Closer was born because I had trouble with killing up processes I set up remotely via SSH. That is, you want to run some SSH process in the background, and then you want to kill it, just like you would a local subprocess.
- Main features:
- kill the remote process (either by choice, or automatically at the end of the calling process)
- capture the remote process’s output
- live monitoring of remote process output
- get a callback upon remote process’ death
Michael #6: Fades
- Fades is a system that automatically handles the virtualenvs in the cases normally found when writing scripts and simple programs, and even helps to administer big projects.
- fades will automagically create a new virtualenv (or reuse a previous created one), installing the necessary dependencies, and execute your script inside that virtualenv, with the only requirement of executing the script with fades and also marking the required dependencies.
- At the moment you execute the script, fades will search a virtualenv with the marked dependencies, if it doesn’t exists fades will create it, and execute the script in that environment.
- Indicating dependencies (in code or via CLI)
import somemodule # fades == 3 import somemodule # fades >= 2.1 import somemodule # fades >=2.1,<2.8,!=2.6.5
- Can control the Python version the env is based upon
- Can ask for a “refresh” on the virtual env
- You can also configure fades using .ini config files.
- How to clean up old virtualenvs?
