Vi, born from the ashes of the ed editor, was created by Bill Joy in 1976. Seeking a more visual and interactive editing experience, Joy leveraged the ex editor, adding the visual mode which became the defining characteristic of "vi" (visual). Later, Bram Moolenaar picked up the torch, porting Vi to the Amiga and significantly expanding its functionality, including multi-level undo, support for multiple files and windows, and an extensible plugin system. This enhanced version became Vim (Vi IMproved), evolving from a simple visual editor into a powerful and highly customizable text editor used by generations of programmers and developers.

Bcvi allows running a full-screen vi editor session over a limited bandwidth or high-latency connection, such as a serial console or SSH connection with significant lag. It achieves this by using a "back-channel" to send screen updates efficiently. Instead of redrawing the entire screen for every change, bcvi only transmits the differences, leading to a significantly more responsive experience. This makes editing files remotely over constrained connections practical, providing a near-native vi experience even with limited bandwidth. The back-channel can be another SSH connection or even a separate serial port, providing flexibility in setup.
Hacker News users discuss the cleverness and potential uses of bcvi, particularly for embedded systems debugging. Some express admiration for the ingenuity of using the back channel for editing, highlighting its usefulness when other methods are unavailable. Others question the practicality due to potential slowness and limitations, suggesting alternatives like ed.
