Mod_python - the long story

Part of it was the lack of surprises, which isn’t Apple’s fault. All of the product upgrades, while nice, were incremental and predictable. None of the pricing was a surprise.

Who better to reinstate public trust in weakened cryptosystems? As an exercise in security that Schneier himself may find interesting, what…
