Sunday Lightning Talks
summary
A grab bag of short demos and lessons with concrete takeaways: a SQL rewrite uses a lateral join to collapse a dozen subselects and claims query time drops from ~230ms to ~80ms; SSH automation with Paramiko shows you must use Paramiko exec (or force exit), always quote shell arguments, and read stdout and stderr separately; a clear primer on bloom filter false positives with hash counts and bucket bits; plus Emacs major-mode tips, a Raspberry Pi library program seeking donations, open‑science badges, and mentoring metrics (≈16 attendees, 46 contest entrants).
