Articles & Tutorials

Handling Cookies is a Minefield (18 minute read)

HTTP cookies are inconsistently handled across browsers and programming languages due to ambiguities in the RFC specifications. These inconsistencies are from mismatches between what servers should send and what browsers must accept, leading to situations where cookies containing perfectly valid characters for browsers are rejected by server-side code. This problem results in unpredictable behavior, with some systems silently dropping cookies and others percent-encoding values or failing completely.
The fallacies of distributed systems (6 minute read)

Some fallacies about distributed systems include assumptions about network reliability, zero latency, infinite bandwidth, and network security. Good distributed systems are designed to handle network unreliability and mitigate latency and bandwidth constraints.
