To enable SharedArrayBuffer, you need to add these headers to the 
text/html files that are meant for the application logic.

If serving via "python -m http.server", look for the file named (something like):
/usr/local/lib/python3.13/http/server.py. 

Then modify SimpleHTTPRequestHandler.send_head as such:

            self.send_header("Content-type", ctype)								# Old
            self.send_header("Content-Length", str(fs[6]))						# Old
            self.send_header("Last-Modified",									# Old
                self.date_time_string(fs.st_mtime))								# Old

            if ctype == "text/html":											# New
                print("*** Setting cross-origin headers on: " + path + " ***")	# New
                self.send_header("Cross-Origin-Opener-Policy","same-origin")	# New
                self.send_header("Cross-Origin-Embedder-Policy","require-corp") # New

            self.end_headers()													# Old
            return f															# Old

Shared link to "lotw" folder on Google Drive:

A. After buying a new chromebook:

1) Put it in developer mode by typing: esc + refresh (F3) + power and 
accepting the risks.

2) Install Chromebrew from: https://github.com/chromebrew/chromebrew

3) Create /usr/local/home 
	$ cd /usr/local && mkdir home

4) Make symlink from to /home/chronos/user/.bashrc from /usr/local/home.bashrc
	$ cd /usr/local/home && ln -s /home/chronos/user/.bashrc .bashrc

5) Edit the .bashrc file and put the following line at the top:
	export HOME=/usr/local/home

6) Near the bottom, put:
	PATH=$PATH:~/bin:~/lotw/bin

7) For a plain, simple prompt, put:
	PS1='\w\$ '

8) Set up aliases like:
	alias nano='nano -x -U -T 4'
	alias c='clear'

9) Source the .bashrc file:
	. .bashrc

	
B. Workflow to create a github repo on a new chromebook

1) Go to github.com
Create github account: <USER>

2) If you want your repo to be statically served at the address:
https://<USER>.github.io, then create a public repo named
<USER>.github.io. (Otherwise, name it anything you want.)
This repo name is <REPO>.

3) Install the gh command:
	crew install github_cli

4) Run these commands

	gh auth login
	git config --global user.email "whatever12345@gmail.com"
	git config --global user.name "Slermerish Yooblex Jankister"
	cd ~/yourproject
	git init
	git branch -m main
	git remote add origin https://github.com/<USER>/<REPO>.git

So a static site repo will look like

	git remote add origin https://github.com/cooluser/cooluser.github.io.git

Otherwise, it will just be:

	git remote add origin https://github.com/myname/coolrepo.git

6) The following commands can be put into a script to automate the syncing of the
remote repo with the local project. 

	cd ~/yourproject 
	git add . 
	git commit -m "Blark" 
	git push -u origin main

7) For Node.js, check to see whether nodebrew is installed. If not, get it from: 
https://github.com/hokaccha/nodebrew. Another option is nvm, node version manager:
https://github.com/nvm-sh/nvm. These projects are used to handle automatic updates
of your Node.js installation.

Create a ~/.node folder so that the Node.js packaging system will not clutter your
home directory.

	mkdir ~/.node

Create a frontend script (called 'npi' or something) for npm like this:

	echo 'npm install $@ --prefix ~/.node' > npi
	chmod +x npi

Use it like so:

	./npi some_node_package

Then you put it into a folder that is in your $PATH.

8) Edit ~/.bashrc and add the following line:

	export NODE_PATH=~/.node/node_modules
