In defense of blocks for local scopes (Part 1)

[EDIT: I've added a part 2 to this blog post, to address some of the feedback that has come up: https://gist.github.com/getify/706e5e10822a298375da40f9cc1fa295]

Recently, this article on "The JavaScript Block Statement" came out, and it received some good discussion in a reddit thread. But the general reaction seems to be against this approach. That saddens me.

How to create a MongoDB server in a OpenStack infrastructure

This tutorial guides thorough the steps needed to implement an Ubuntu 20.04 OpenStack instance running a MongoDB server. The resulting server is opened only to hosts inside the infrastructure, and is optionally accessible from the outside using ssh. The data of the database are hosted in a single OpenStack volume, data replication is not covered here.

The steps are the following:

• creation of the compute instance
• creation of the volume
• linking the volume to the instance
• install mongodb

// This command will give you list of available FFMPEG formats and their default Mime types
// ffmpeg -formats -hide_banner | tail -n +5 | cut -c5- | cut -d' ' -f1 | xargs -i{} ffmpeg -hide_banner -h demuxer={} | pcregrep -o2 -o4 -M  '(Muxer (\w+) )|(Mime type:( .*).)'
// And then parse the output with regex to JSON format in JavaScript for example:
// str.match(/(.*)\n (.*)/gm).map(m => `"${m.replace(/\n /, '": "')}"`).join(',\n');

// Combine the output with MDN - Common MIME types
// https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types/Common_types
// And with IANA:

Everything I Know About UI Routing

Definitions

1. Location - The location of the application. Usually just a URL, but the location can contain multiple pieces of information that can be used by an app
   1. pathname - The "file/directory" portion of the URL, like invoices/123
   2. search - The stuff after ? in a URL like /assignments?showGrades=1.
   3. query - A parsed version of search, usually an object but not a standard browser feature.
   4. hash - The # portion of the URL. This is not available to servers in request.url so its client only. By default it means which part of the page the user should be scrolled to, but developers use it for various things.
   5. state - Object associated with a location. Think of it like a hidden URL query. It's state you want to keep with a specific location, but you don't want it to be visible in the URL.

How to setup a development environment where Git from WSL integrates with native Windows applications, using the Windows home folder as the WSL home and using Git from WSL for all tools.

Note if using Git for Windows, or any tool on the Windows side that does not use Git from WSL then there will likely be problems with file permissions if using those files from inside WSL.

Tools

These are the tools I use:

• git (wsl) - Command line git from within WSL.
• Fork (windows) - Git GUI (must be used with wslgit)
• wslgit - Makes git from WSL available for Windows applications. Important! Follow the installation instructions and do (at least) the first optional step and then the Usage in Fork instructions.
