Ask HN: What are you doing now to profit from the current or upcoming recession?

I see comments on HN once in a while about how they did [clever thing X] during a recession years ago and made money. With volatility comes profit potential, and it seems clear to everyone that rough seas are ahead. What are people doing now to potentially profit, or at least insulate themselves, during this? I liquidated my discretionary equities portfolio (not much in it anyway) about a year ago already. Still have my retirement in its roboadvisor mix of bonds, equities and don't plan to touch it. Wondering if it might be worthwhile to invest in short ETFs like SH, SQQQ.

Hello HN! I became frustrated with the unpredictible/poor match quality and opaqueness of "relevance scores" in existing fuzzy and fulltext search libs, so I tried something different and this is the result. The main selling point is the result quality / ordering, with best-in-class memory overhead and excellent performance being bonuses. The API is pretty stable at this point, but looking for feedback before committing to 1.0. TL;DR The test corpus is a 4MB json file with 162k words/phrases, so give it a second for initial download. You can also drag/drop your own text/json corpus into the UI to try it against your own dataset. Live demo/compare with a few other libs (there are many more in the codebase, in various states of completion, WIP): https://ift.tt/xUYcTCe... In isolation for perf assessment: https://ift.tt/xUYcTCe... To increase fuzziness and get broader results, try setting intraMax=1 (core) and enable outOfOrder (userland): https://ift.tt/xUYcTCe... Also play with the sortPreset selector to swap out the default Array.sort() for one in userland that prioritizes typehead-ness (the resultset remains identical). Still TODO: - Example of stripping diacritics - Example of using non-latin charsets - Example of prefix-caching to improve typeahead perf even further - Example of poor man's document search (matching multiple object properties) That's all, thanks!
