In English, the five vowels plus R, S, T, L, N account for over 68% of all letter occurrences. Guessing a high-frequency vowel first doesn't just avoid wrong-guess penalties—it partitions the remaining dictionary space by the exact positions revealed, maximizing Shannon information bits per guess.
By writing CameLcase, LearningLab, and SLog with an explicit capital L, students immediately distinguish L from 1 and I—and never get tripped up by Linux's case-sensitive file paths!
l
In sans-serif fonts, lowercase l (ASCII 108), uppercase I (ASCII 73), and numeral 1 (ASCII 49) look nearly identical. On Linux servers (Apache/Bluehost), URLs after the / are strictly case-sensitive—so we standardize on CameLcase (/LearningLab, SLog, FlippingDice, TopHat).
Every LearningLab in the Twisted23 Parlour stamps events using the 38-character alphabet (0-9, A-Z, |, ^—capital L only, zero lowercase ls!) counting seconds since March 18, 2020:
