Choosing a Public DNS Resolver

Evidence Encrypted transports (DoH and DoT) add latency per query, yet whole-page load times are often close to plain DNS, and DoH's overhead is small in practice. On lossy or high-latency links, plain Do53 still wins. Performance also varies by provider and region, so the fastest resolver depends on where you are.

The Galapagos Islands, where Charles Darwin visited in 1835, are a unique ecosystem where animals have evolved in isolation, leading to distinct species. Darwin's visit and subsequent theory of evolution were influenced by his observations of the islands' wildlife, but his ideas were also shaped by his experiences and interactions with humans.

How do you keep Web MIDI from crashing a 1983 synthesizer?

Writing Web MIDI code for 8-bit CPUs from the 1980s is a timing nightmare due to buffer overflow caused by modern computers sending data too fast. To safely control data flows, use chunking and pacing to limit blocks and wait for the vintage CPU to write data.
