SQLite's Use of Tcl (2017)
The design of SQLite was inspired by the design of TCL, both in the way it handles datatypes and in the formatting of its source code. The index use case for SQLite was in a Tcl/Tk application for an industrial company. From its inception, SQLite has always depended heavily on TCL. These days, SQLite no longer uses…

Rust: Investigating an Out of Memory Error
TL;DR: We discovered the hard way that when backtrace is enabled, the anyhow library is capturing a backtrace on every error. Only when printing this error in debug format!(”err: {:?}”, error) backtrace’s symbols are resolved to human-friendly names, thus leading to a significant memory increase for your application…
