repo2docker (via) Neat tool from the Jupyter project team: run “jupyter-repo2docker https://github.com/norvig/pytudes” and it will pull a GitHub repository, create a new Docker container for it, install Jupyter and launch a Jupyter instance for you to start trying out the library. I’ve been doing this by hand using virtual environments, but using Docker for even cleaner isolation seems like a smart improvement. # 10:06 pm
BigInt: arbitrary-precision integers in JavaScript (via) The BigInt specification is now supported in Chrome—but it hasn’t yet made it to other browsers. The Chrome team have a really interesting solution: they’ve released a JSBI library which you can use to do BigInt calculations in any browser today, and an accompanying Babel plugin which can rewrite calls to that library into BigInt syntax once browser support catches up. I’ve never seen a library that includes a tool for refactoring itself into oblivion before. # 2:22 am
AWS Ground Station – Ingest and Process Data from Orbiting Satellites. OK this is cool. “Instead of building your own ground station or entering in to a long-term contract, you can make use of AWS Ground Station on an as-needed, pay-as-you-go basis. [...] You don’t need to build or maintain antennas, and can focus on your work or research. We’re starting out with a pair of ground stations today, and will have 12 in operation by mid-2019. Each ground station is associated with a particular AWS Region; the raw analog data from the satellite is processed by our modem digitizer into a data stream (in what is formally known as VITA 49 baseband or VITA 49 RF over IP data streams) and routed to an EC2 instance that is responsible for doing the signal processing to turn it into a byte stream.” # 1:04 am
