WorkOS has published an extensive guide on how one-time passwords work, their benefits, and implementation details.

Some highlights:

• “OTPs come in three different forms, and each form works differently: time-synchronized OTPs, lockstep synchronized OTPs, or transmission-based OTPs”

Tags: tdd, philosophy

Kent Beck illuminates an essential skill that he believes is required for effective test-driven development (tdd).

Some highlights:

• “The ability to break a big complicated behavior into pieces,”

• “In such a way that implementing & verifying those pieces implies that the whole behavior acts as expected,”

• “And the confidence to work this process.”
