The bucket brigade device: An analog shift register
Nov 14, 2024 (Electronics) Nowadays, digitally delaying audio is easy, but historically we had to use devices like the TCA350, a fully analog delay line: It works by charging a small capacitor to the input voltage, and then moving that charge through a chain of hundreds more before it exists the device: The two clock […]

Show HN: Retry a command with exponential backoff and jitter (+ Starlark exprs)
recur is a command-line tool that runs a single command repeatedly until it succeeds or no more attempts are left. It implements optional exponential backoff with configurable jitter. It lets you write the success condition in Starlark. Requirements Go 1.19 POSIX Make for testing Installation Install Go, then run the following command: go install github.com/dbohdan/recur@latest
Reducing the cost of a single Google Cloud Dataflow Pipeline by Over 60%
In this article we’ll present methods for efficiently optimizing physical resources and fine-tuning the configuration of a Google Cloud Platform (GCP) Dataflow pipeline in order to achieve cost reductions. Optimization will be presented as a real-life scenario, which will be performed in stages. Before we start, it’s time to introduce several avenues through which the […]
