Directories aren’t surging. There isn’t this nascent directory movement fomenting - ready to take on the world. Directories aren’t trending.
But there is a certainly really sweet little directory community now. From the Marijn-inspired stuff listed in Directory Uprising to the link-sharing ‘yesterweb’ collected around sadgrl.online - or the originals at Indieseek and i.webthings.
Barnsworthburning (by Nick Trombley) is a very formidable addition to this community - a clean, multilayered design and an innovative bidirectional index.
In order that the mind may not be taxed, moreover, by the manifold and confused reading of so many such things, and in order to prevent the escape of something valuable that we have read, heard, or discovered through the process of thinking itself, it will be found very useful to entrust to notebooks...those things which seem noteworthy and striking.
A Fermi estimate is a quick-and-dirty solution to an arbitrary scientific or engineering analysis problem. Fermi estimation uses widely known numbers, readily observable phenomenology, basic physics equations, and a bunch of approximation techniques to arrive at rough answers that tend to be correct within an order of magnitude or so. The term is named for Enrico Fermi, who was famously good at this sort of thing.
…It struck me that there is counterpart to this kind of thinking on the synthesis side, where you use similar techniques to arrive at a very rough design for a complex engineered artifact. I call such a design approach Dyson design, after the physicist Freeman Dyson, who was one of the best practitioners of it (not to be confused with inventor James Dyson, whose designs, ironically, are not Dyson designs).
