Ask HN: What are you doing now to profit from the current or upcoming recession?
20 by carabiner | 12 comments on Hacker News.
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.

New top story on Hacker News: Show HN: uFuzzy.js – A tiny, efficient fuzzy search that doesn't suck
Show HN: uFuzzy.js – A tiny, efficient fuzzy search that doesn't suck
13 by leeoniya | 0 comments on Hacker News.
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!

Ask HN: Has the Apple Silicon excessive disk read/write issue been fixed?
30 by cool_hw | 11 comments on Hacker News.
This was a discussion when M1 macbooks were launched, and Apple supposedly addressed it in an OS update (macOS 11.4). But I'm seeing really high read/write numbers. I'm aware that SSD lifespans are long and TBW spec is pretty generous. Still, compared to my linux machines, this seems extraordinarily high. On my newish M1 MBA, with the latest updates, with barely any use, 98%+ sleep, I'm seeing about 3 to 5 GB reads per day and 2 to 4 GB writes per day. Latest report from smartctl. ---------------------------------------------------- === START OF SMART DATA SECTION === SMART overall-health self-assessment test result: PASSED SMART/Health Information (NVMe Log 0x02) Critical Warning: 0x00 Temperature: 27 Celsius Available Spare: 100% Available Spare Threshold: 99% Percentage Used: 0% Data Units Read: 716,195 [366 GB] Data Units Written: 616,232 [315 GB] Host Read Commands: 9,108,273 Host Write Commands: 6,947,397 Controller Busy Time: 0 Power Cycles: 95 Power On Hours: 5 Unsafe Shutdowns: 11 Media and Data Integrity Errors: 0 Error Information Log Entries: 0 ---------------------------------------------------- M1 Air 16GB 1TB.

This article did not shock me at all but somehow looking up the numbers on Docusign made me wonder, seriously, and with all due respect: how would you get to 7,400 employees at Docusign? I literally can't do back-of-the-napkin calculations that make it plausible. https://ift.tt/YQuF6al

Ask HN: Books on designing disk-optimized data structures?
6 by memset | 4 comments on Hacker News.
Are there canonical books, resources, or readings for how to design data structures that will be primarily read and written to a disk rather than memory? Most of what I learned in school about big-O assumes that, for example, random access is O(1). However, random disk reads are really slow due to spacial locality. People who write databases obviously have solutions to this problem - for example, DuckDB is based on a number of papers that have come out over the years on this topic. If I wanted to design, ie, a tree structure which was intended to be read/written from a disk, are there general principles or patterns the have been developed to take advantage of locality of reference, minimize random reads, or decrease the overhead of writes, that I could familiarize myself with? What is the CLRS for disk?

Sharing this funny story so that people won't feel alone when it happen to them. It seems my first and only reddit account created two hours ago is shadow-banned since the very beginning, tried one comment on /r/cpp and one post on /r/rust, nobody ever seen them other than one kind mod that confirmed there's nothing they can do. Even funnier is that there is a subreddit /r/ShadowBan dedicated to test shadowban and some obvious spam-bot accounts are not banned yet mine is. related: [1] https://ift.tt/WbQFae4 [2] https://ift.tt/m3q8nRt

Show HN: TaskTXT, plain text task-timing notepad
10 by trafnar | 6 comments on Hacker News.
I built TaskTXT.com based on my experience timing my tasks. I found that committing to a task before I start helps with my focus, and guessing how long it will take, then timing it prevents me from wanting to give in to distractions because I'm "on the clock". Video Overview: https://www.youtube.com/watch?v=HOYO0c_D6w0 There's also a Mac app which you can download here: https://ift.tt/R6HtKbM Video overview of the Mac app: https://www.youtube.com/watch?v=qMs-V5v5gZY But I didn't want the tool to be distracting, so its based on plain text. That means the UI is very familiar and you can use it for generic notes in any structure you like. When you work in TaskTXT you are working directly on its data format, I made a video about this concept here: https://www.youtube.com/watch?v=kZdBgVZn5NI I think this tool is uniquely suited for programmers, so I'd be interested to hear any feedback about the product, or its viability as a business.
