Pure ESM package

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

  1. Use ESM yourself. (preferred)
    Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
  2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
  3. Stay on the existing version of the package until you can move to ESM.

Legal Robot's options for helmet.js

Security Headers at Legal Robot

We're big fans of open source software at Legal Robot. We also know that getting security right is a tough job, so we want to share some of the useful tools we use to build and run Legal Robot and keep it secure.

We are also proud to run Legal Robot on the Meteor framework for Node.js. With this recent change, Helmet.js becomes the official recommendation for security headers in Meteor, replacing the previous Meteor browser-policy package.

One of the most helpful tools in our Meteor security toolbox at Legal Robot is Content Security Policy (CSP)  — basically, our server tells the browser what code it is allowed to run and how to handle something like code injection from a malicious browser extension.

CSP can be quite tricky, but there are some excellent tools out there to help, like [Google'

Creating German diceware wordlist from Open Thesaurus for six-sided dice
#!/bin/bash
: <<'COMMENT'
This script takes the dataset from the Open Thesaurus project and
transforms it to a wordlist comparable to the original diceware list.
I thought the original list contains too much lines which just don't
make any sense and/or are hard to memorize. So my goal was to
automatically generate a list containing only memorable words, which
can then be used to add your own special characters or variations.

This Windows 10 Setup Script turns off a bunch of unnecessary Windows 10 telemetery, bloatware, & privacy things. Not guaranteed to catch everything. Review and tweak before running. Reboot after running. Scripts for reversing are included and commented. Fork of https://github.com/Disassembler0/Win10-Initial-Setup-Script (different defaults). N.…
