Brian #1: pynb: Jupyter Notebooks as plain Python code with embedded Markdown text

pynb lets you manage Jupyter notebooks as plain Python code with embedded Markdown text, enabling:
- Python development environment: Use your preferred IDE/editor, ensure style compliance, navigate, refactor, and test your notebooks as regular Python code.
- Version control: Track changes, review pull requests and merge conflicts as with regular Python code. The cell outputs are stored separately and don't interfere with versioning.
- Consistent execution state: Never lose track again of the execution state. Notebooks are always executed from clean iPython kernels and the cell execution is cached.
You also get parameterized notebooks with batch and programmatic execution.

Michael #2: Microsoft’s quantum computing language is now available for m acOS

New language Q# (snippet examples)
How do you run a quantum app?
Based on topological qubits and quantum computers
Now out on macOS & Linux
Need to use VS Code (and vs code extension)
Comes with Python interoperability (only other language)
Also in Jupyter
Some real-world examples. See this Wired article.
- D-wave
- IBM is making quantum computers commercially available. Since 2016, it has offered researchers the chance to run experiments on a five-qubit quantum computer via the cloud and at the end of 2017 started making its 20-qubit system available online too.

Python beats C# in usage for the first time
Languages:
- Most loved: #1 Rust, #2 Kotlin, #3 Python
- Most dreaded: VB 6 and CoffeeScript
- Most wanted: #1 Python 25%, #JavaScript 19%, #3 Go 16%
Databases:
- Loved: PostgreSQL

Brian #5: demoshell

@doughellmann
Doug Hellman (@doughellmann) announces demoshell
- Inspired by a tweet from @genehack “Hey, speakers, if you're doing live demos in a shell, clear the screen after every command to get the prompt back at the top, so folks in the back can see what you're doing.”
demoshell is a simplified shell for live demonstrations. It always shows the command prompt at the top of the screen and pushes command output down instead of letting it scroll up.
In his words: “I put it up there to start a discussion. I’d be happy if a bunch of people showed up and wanted to take it over and actually turn it into something useful. I invite people to give it a look. And warn them that too much interest is going to be met with commit privileges on the repo. :-)”

Michael #6: Clear statement on Python 2 EOL

Will there be a period where Py2.7 is in security-only status before hitting EOL?
via Nicola Iarocci‏ @nicolaiarocci
- Yay, @gvanrossum makes it adamantly clear: “Let's not play games with semantics. The way I see the situation for 2.7 is that EOL is January 1st, 2020, and there will be no updates, not even source-only security patches, after that date.” https://buff.ly/2pbZmBZ
Support (from the core devs, the PSF, and python.org) stops completely on that date.
