Nano ID
A secure, URL-friendly, unique string ID generator for JavaScript
Nano ID is a library for generating random IDs. Likewise UUID, there is a probability of duplicate IDs. However, this probability is extremely small. Meanwhile, a lot of projects generate IDs in small numbers. For those projects, the ID length could be reduced without risk. This calculator aims to help you realize the extent to which the ID length can be reduced. Instead of using the unsafe Math.random(), Nano ID uses the crypto module in Node.js and the Web Crypto API in browsers. These modules use unpredictable hardware random generator. Uniformity, random % alphabet is a popular mistake to make when coding an ID generator. The distribution will not be even; there will be a lower chance for some symbols to appear compared to others. So, it will reduce the number of tries when brute-forcing. Nano ID uses a better algorithm and is tested for uniformity. -

Error Propagation Calculator
Easily propagate measurement errors through mathematical operations.
Error Propagation Calculator is essentially a cross-platform GUI front-end for the Python Uncertainties library that does not require knowledge of Python to use. Simply point and click to enter values and errors, input your expression and press compute. The program evaluates native Python code, but the user does not need to know the syntax as common operators are provided as buttons, similar to a scientific calculator. -Evaluate expressions with as much as 26 different variable and error pairs. -Copy output to the system clipboard by simply double clicking the output field. -Cross-platform: Works on Windows, Linux, and Mac. All calculations are dependent on the uncertainties package (Uncertainties: a Python package for calculations with uncertainties, Eric O. LEBIGOT, http://pythonhosted.org/uncertainties/) -
