Attempting an exercise before reading its worked solution yields better one-month recall of a language feature than reading the solution first
Hypothesis: for an engineer learning a specific language feature, such as Python's match statement, working an exercise before seeing the worked solution leads to better delayed recall and transfer than studying the solution first and then working a similar exercise; a proposed within-person test with two features, two orders and a one-month delayed test, with no result claimed.

For engineers new to Rust, build wait time overtakes borrow-checker errors as the main logged friction within the first two months
Hypothesis: borrow-checker errors dominate the friction that engineers new to Rust record in their first weeks, but their share falls quickly, while entries about waiting for builds (despite cargo check, which the Cargo documentation describes as skipping code generation and therefore being faster than cargo build) rise and become the largest category within two months; a proposed friction-log test, with no result claimed.
