The Silurian Hypothesis: It was the Cephalopods. Text, footage and photographs by Dr. Klaus M. Stiefel. A hypothesis called “The Silurian hypothesis” wins the title of “most interesting hypothesis most likely to be false” for all of science. In brief, the hypothesis postulates that previously a species different from ours had achieved high intelligence and technological civilization on this planet. The Silurian hypothesis (named after “Silurian” aliens in the brainy British TV series “Doctor Who”) was initially proposed by two astronomers, Gavin A. Schmidt and Adam Frank, as a thought experiment, to see if it would even be feasible to detect the traces of such a hypothetical civilization which had existed many millions of years ago. (more)

A pyramid (from Ancient Greek πυραμίς (puramís) 'pyramid',[1][2] from the Egyptian pir-em-us, the vertical height of the structure.[3]) is a structure whose visible surfaces are triangular in broad outline and converge toward the top, making the appearance roughly a pyramid in the geometric sense. The base of a pyramid can be of any polygon shape, such as triangular or quadrilateral, and its surface-lines either filled or stepped. https://en.wikipedia.org/wiki/Pyramid (more)

David Singleton: Coding agents have crossed a chasm. If I imagine a ladder of our evolving relationship with coding agents, we’ve climbed to a new rung. We’ve moved from “smarter autocomplete” and “over the shoulder helper” to genuine “delegate-to” relationships - they’re like eager and determined interns. (more)

aka Feature Flag, see also A/B Test. Feature Toggles (often also refered to as Feature Flags) are a powerful technique, allowing teams to modify system behavior without changing code. They fall into various usage categories, and it's important to take that categorization into account when implementing and managing toggles. Toggles introduce complexity. We can keep that complexity in check by using smart toggle implementation practices and appropriate tools to manage our toggle configuration, but we should also aim to constrain the number of toggles in our system.
