Progress Monitoring HTTP Requests in Installed Apps
This is a note about the pitfalls of progress monitoring HTTP requests sent from an installed app (i.e. not web app running in a browser). Ideally, we’d like to know how long an HTTP POST is going to take, and update the percent-completed visually so that when it reaches 100% the operation is neatly finished […]

Node.js Asynchronous Methods that Return Objects

Binary vs Text Transfers (SFTP / FTP)
This post clarifies the topic of binary vs. ascii uploads/downloads for SFTP (Secure File Transfer over SSH) and FTP. Binary mode transmits bytes exactly as-is. Text mode (also known as “ascii” mode) can modify line endings (CR’s and LF’s) to the canonical convention used on the remote system. For example, Linux systems typically use […]
