New top story on Hacker News: Ask HN: Best Office Chair?
Ask HN: Best Office Chair?
12 by brundolf | 11 comments on Hacker News.
My home desk-chair is nearly ten years old at this point, and wasn't anything special even when it was new. This is starting to become pretty noticeable now that I'm using it for eight hours every day. Anybody have recommendations for their favorite office/desk chair? I don't want anything huge or ungainly, and ideally not one of those garish "gamer chairs". Something minimalist but comfy, and durable, and good for your back. I've really enjoyed those mesh-based chairs in the past, though I don't remember any specific brands.

Hello all. Most of the books out there on the stock market are these flashy title kind of books promising to make you money. I'm instead interested at learning about the systems at play with the stock market as the whole thing has always confused me. Books/Articles/Online Courses will be appreciated!

Ask HN: Unemployed. What on earth should I do with my life?
17 by confused-c | 7 comments on Hacker News.
I've been unemployed for several months. I don't know what my next job will be, or how to get it. I humbly request your advice on: "What jobs should CC seek, and not seek? How can CC provide value to others?" Skills/talents: I'm much more interested in "how do I get $THING working enough to accomplish important tasks?" than "how do I optimize $THING performance?" My last job was in a CS research lab; I did no computer science but plenty of automation and process-improvement. I've written & implemented a text adventure. Emacs diehard. BA Linguistics (5 years analyzing patterns in syntax, semantics.) Outside computering, I'm a keen writer: between my journal and my website, I produce >100,000 words a year. I consistently make others laugh: in conversation, on stage, and through writing. I've been a Chinese translator and have decent spoken Mandarin. I've already: Applied to hundreds of jobs (interviewed for perhaps ten). Translator positions ask for native Mandarin and good English, not the other way around. Engineer roles select for those who can whip out perfect algo/DS on command (I understand the need for expertise, but my IRL experience is that not having the perfect construct memorized is never the bottleneck to success.) I've had "data analyst" interviews, but no offers, and no clinical research analyst callbacks despite having done that job. Sent loads of cold emails. Volunteered with techy/Chinesey nonprofits/meetups/interest groups. This has brought friends, satisfaction, and board membership, but not career advancement -- and COVID-19 has frozen all events. I'm now: Applying to automation-engineer jobs (thanks, HN "Who's Hiring.") Building server development skills: learning Flask, EC2. Looking at videogame writer jobs. Seeking out startups/small firms that might react positively to who I am/what I do. Considering grad school. My resume and I are at confused.computerman@gmail.com. Thank you for reading. Have a pleasant day. CC

Suggest HN: No April Fools this year
42 by bryanrasmussen | 17 comments on Hacker News.
As you get near April Fools, and need to deploy your prank pages, perhaps reconsider doing it. As a general rule April Fools has become less popular on the web the more widespread it has become, and some people might take levity badly given the current world situation - I myself am among the party of people who think everything is open to mockery, but only if the jokes are good. Most April Fools pranks are tedious. Obviously you may not have the ultimate say in what pranks are to be played at your company on the world, but perhaps you can push back on them and point out they might not be as well received as in years past.

Ask HN: How to Self Study Physics?

Hey HN, I'm a CS graduate student, and I do a lot of Deep Learning Research. I've always wanted to get a strong foundation in Physics, and while on lockdown because of COVID, I thought it would be a great opportunity. I've run across this incredible guide https://ift.tt/2kPZYcv and I was also thinking about going through MIT Open Courseware following their bachelor's curriculum. Do you all have any suggestions or tips? I really appreciate it!

Ask HN: How would you improve this bash oneliner for deleting tweets?
9 by jamiehall | 2 comments on Hacker News.
Many people use tweet deletion services, which periodically remove everything from their Twitter timeline; I wondered if it could be done from a Bash command line. I wrote up my experiences as an explainer for nontechnical people: https://ift.tt/2y1gdzB... TL;DR, here is the oneliner I've been using: $ twurl "/1.1/statuses/user_timeline.json?screen_name=YOUR_TWITTER_HANDLE&count=200 &max_id=$( twurl '/1.1/statuses/user_timeline.json?screen_name=YOUR_TWITTER_HANDLE&count=200&include_rts=1' | jq -c -r '.[] | .id_str' | head -10 | tail -1) &include_rts=1" | jq -c -r '.[] | .id_str' | parallel -j 10 -a - twurl -X POST /1.1/statuses/destroy/{1}.json > /dev/null [Edit: I've put line breaks in there to make it more legible.] I'm curious if it's possible to do better. In particular: could this be more elegant? Is it possible to do it using common built-ins, instead of twurl and jq? Any suggestions or improvements would be very welcome!

Ask HN: Outreach for Covid-19 longitudinal study proposal?
13 by william-at-rain | 2 comments on Hacker News.
I'm failing at finding development help for a COVID-19 study initiative. I could use your ideas and critiques. https://ift.tt/2IZSimr... BACKGROUND: A small nonprofit called RAIN in Tacoma just bought and set up blood gathering and testing equipment, and they have an antigen test for SARS-CoV-2 ready to go. Sample collection starts next week, with an eye to scaling to many thousands in the Tacoma area. PhDs in immunology, microbiology, and virology are heading up the effort. They need some technology beyond what they know on the market, and (since it's a nonprofit) they called up volunteers. I'm a volunteer, and I wrote the markdown doc in the gist. The idea is to make longitudinal studies possible for persons that are tested for COVID-19. How can I find help to make this happen for our town?

Hello HN. I'm working at a place where, according to a very credible and personally-detailed report, has had a known positive Covid-19 case. It was later denied. It seems pretty clear what's going on. I'm now seeing my teammates become sick, and still it has been decided that we must not work from home, despite that being possible. It's hard to understand why critical human resources are being put at risk. It's hard to understand why I'm putting up with this. It's hard to understand why I feel like I'm cannot share more details about the situation. I really feel like I need to talk with someone about it. Anyone else? Thank you.
