Node.js strict mode enabled?

A quick test, this relies on the fact that this will not exist and point to the global scope when running in strict mode.

console.log('strict:',(function() { return (this === undefined); })());

Strict mode is enabled by default within Node.js ES module enabled packages:

Install jq on macOS from source

A quick n' dirty Bash script to install the following:

• autoconf.
• automake.
• libtool
• jq - from source.

The aim/need was to create an M1 (ARM64) compile of jq - which isn't available (currently) via releases and avoid using Homebrew.

npm wrapper to ensure npm publish from clean Git commit

By default npm publish will publish all files within a working directory (excluding .gitignore / .npmignore / package-lock.json).

This is typically fine - but often I find myself leaving un-staged files (e.g. TODO.txt files) in a repository root and these of course get accidently taken along for the publish ride.

The helper script npm-publish-wrap.sh will catch calls to npm publish and:

• Ensure I'm at the root of a repository (.git directory) found.
• Local git clone the current repository to a temp directory - removing any unstaged files.

Here is a lo-fi method of pulling it from the web UI DOM:

• Visit the Integrations page for your Datadog account.
• Open browser web developer tools.
• Execute the following from the JavaScript console:

Python threaded workers using ThreadPoolExecutor()

A pattern for using concurrent.futures.ThreadPoolExecutor() to execute a series of "worker" functions in parallel, processing a queue of assigned "work".

How it works:

• worker_init() creates:
  • Queues for "work" and "results".
  • A threading.Event() to denote "no more work in queue".
  • A futures.ThreadPoolExecutor().
