CORE DEFINITION

The minimum number of single-character edit operations (insertions, deletions, or substitutions) required to transform one string into another.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Assess transformation cost. When you want to change careers or habits, calculate the 'edit distance'. The distance from 'programmer' to 'technical writer' is short (only need to replace some skills); the distance from 'programmer' to 'doctor' is extremely long. Choose a path whose distance is within an acceptable range, or reserve sufficient resources to pay the high editing cost.

Zero-Knowledge Proof

In cryptography, a zero-knowledge proof or zero-knowledge protocol is a method by which one party (the prover) can prove to another party (the verifier) that a given statement is true, without conveying any information apart from the fact that the statement is indeed true. Thus, it can be understood as a 'zero-leakage proof'.

Batching

A batch file is a script file in DOS, OS/2, and Microsoft Windows, used as a scripting language to run programs. It is a text file containing a series of commands to be read and executed by an interpreter with a command-line interface. It is applied in DOS and Windows systems, interpreted and run by the built-in interpreter (usually COMMAND.COM or CMD.EXE). It is equivalent to a shell script in Unix-like systems. In DOS and Windows 9x operating system families, the file extension for batch files is .bat. In OS/2 and Windows NT families, the .cmd extension is added. In other operating systems, batch files may have different extensions, for example, 4OS, 4OS2, and 4NT use the .btm extension. When a batch file is executed, the shell program reads the file content and then executes its commands, typically line by line.

Head-of-Line Blocking

Head-of-line blocking (HOL blocking) is a performance-limiting phenomenon in computer networking. It occurs when the first packet in a queue (the head) is blocked, causing the entire queue of packets to be blocked. This can happen in switches with buffered inputs, due to out-of-order transmission, or in HTTP pipelining with multiple requests.
