SIM Card Management Over GSM Modem

A small guide on how to send and receive USSD codes on Linux

I am using the built in GSM (UMTS) modem of my Thinkpad X1 extensively because I am often in places with flaky internet connections. I connect through the standard Network Manager on Ubuntu and everything works fine. There was one major annoyance though. Every time I wanted to top up the SIM balance or book a new package, I needed a phone to send and receive USSD codes. So I took some time to figure out how to do it from the shell. I wrote this down as a help for others and a reminder for myself. Without further ado...

First intsall gammu and picocom.

➜  ~  sudo apt-get install -y gammu picocom

Reference: RFC 2616 - HTTP Status Code Definitions

• HTTP/1.1 Status Code Definitions
• Additional HTTP Status Codes

General

• 400 BAD REQUEST: The request was invalid or cannot be otherwise served. An accompanying error message will explain further. For security reasons, requests without authentication are considered invalid and will yield this response.
• 401 UNAUTHORIZED: The authentication credentials are missing, or if supplied are not valid or not sufficient to access the resource.
• 403 FORBIDDEN: The request has been refused. See the accompanying message for the specific reason (most likely for exceeding rate limit).
• 404 NOT FOUND: The URI requested is invalid or the resource requested does not exists.
• 406 NOT ACCEPTABLE: The request specified an invalid format.

This example shows how you can use your data structure as a basis for 
your Firebase security rules to implement role-based security. We store
each user by their Twitter uid, and use the following simplistic approach
for user roles:

0 - GUEST
10 - USER
20 - MODERATOR

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Falsehoods programmers believe about prices

1. You can store a price in a floating point variable.
2. All currencies are subdivided in 1/100th units (like US dollar/cents, euro/eurocents etc.).
3. All currencies are subdivided in decimal units (like dinar/fils)
4. All currencies currently in circulation are subdivided in decimal units. (to exclude shillings, pennies) (counter-example: MGA)
5. All currencies are subdivided. (counter-examples: KRW, COP, JPY... Or subdivisions can be deprecated.)
6. Prices can't have more precision than the smaller sub-unit of the currency. (e.g. gas prices)
7. For any currency you can have a price of 1. (ZWL)
8. Every country has its own currency. (EUR is the best example, but also Franc CFA, etc.)

ACL / Roles + Permissions

https://github.com/djvirgen/virgen-acl Simple and elegant, create your own checks. No middleware?

https://github.com/OptimalBits/node_acl Use as middleware, create your own roles and access. Great choice.

https://github.com/tschaub/authorized Similar to connect roles... but a bit more robust? you can create roles and action, and associate many roles with that action

Secure sessions are easy, but not very well documented.  
Here's a recipe for secure sessions in Node.js when NginX is used as an SSL proxy:

The desired configuration for using NginX as an SSL proxy is to offload SSL processing 
and to put a hardened web server in front of your Node.js application, like:

[NODE.JS APP] <- HTTP -> [NginX] <- HTTPS -> [PUBLIC INTERNET] <-> [CLIENT]

Edit for express 4.X and >:  Express no longer uses Connect as its middleware framework, it implements its own now.
