Adventures in TCP latency measurement
Ceri Storey wrote “ Recently, Google have published an article on BRR, an algorithm that explicitly measures the round-trip latency and bandwidth capacity of the link between two machines (be it in a datacenter, or a mobile phone) to avoid sending more traffic than is useful, causing queues to build up in the network that needlessly increase latency. So… ”
Dynamically generating mocha tests
Antonio Bebiano wrote “ My first project at OW Labs was the development of World Energy Council’s trilemma index tool. This tool’s main purpose is to enable users to see how worldwide countries rank against three variables: energy security, energy equity and environmental sustainability. If you would like to know more about these variables go ahead and check the… ”
Testing with Traces?
Matthew Sackman wrote “ Most APIs and type signatures are hopelessly inadequate for capturing and describing a model. For example, consider a map and the signatures for put and get. Even if you have pure functional type signatures, the signatures on their own convey no information about what they do with a key and value during put. For this…”
Cross-grading for fun and profit
Tom Parker wrote “ First thing you’re probably wondering: What’s cross-grading? Well, it’s a bit like upgrading, except more sidewise than definitely upwards. It involves the changing of the architecture of a system, most typically from 32-bit to 64-bit, and most typically from x86 to x86-64 (although similar options are apparently doable for other architecture families, including ARM, MIPS and… ”
