Re:I'm Tired of Talking to AI on Friday May 29, 2026 @11:57AM (#48324908)
I agree that devices/internet/AI can pull you away from the life around you. In my apartment building, though, we have a group chat to coordinate laundry schedules for the laundry machines on the first floor. It started during Covid and continued even after and with new people moving in. It's turned into a nice, helpful conversation about not only laundry but packages and street parking and more. It's helped to get to know the neighbors better than without.
Re:Python learners – review this free courseware on Tuesday January 13, 2026 @06:08PM (#46609731)
Join our Python courseware project and help improve a free, beginner-friendly curriculum designed to make students internship- and interview-ready.

You’ll work through the course like a student would, identify what’s confusing or missing, and help us refine the lessons so they land cleanly.

While you review and provide feedback, you’ll also build a realistic portfolio project you can confidently demo, explain, and defend in internship and job interviews. You’ll have an industry mentor (me!) to help you move faster, avoid dead ends, and build real confidence.

Re:NASA's Curiosity Rover Just Spent Its 2,000th Day on Mars on Saturday March 24, 2018 @11:35AM (#16667105)
This number is in Sols, Martian days. I believe Curiousity landed on Mars on Aug 6, 2012, which makes it 2056 Earth days.

Re:In Raising the World’s I.Q., the Secret’s in the Salt (2006) on Tuesday December 19, 2017 @11:15AM (#15961200)
Small factoid: I visited the Tobacco and Salt Museum in Tokyo and found out that Japan was forced to develop domestic salt technology due to isolation plus climate factors (cool temperatures and heavy rainfall). It's not just a historical topic. With increased use of soda and soda derivatives in modern industry salt now has an important role to play in advanced technologies.

Ask HN: What makes a good online community?

Posted by jcasman on Saturday December 09, 2017 @01:14PM
from the ask-hn dept.

I'm interested in what makes a good online community. Is it the community software with rules and reputation and gamification? Is it the moderators that help enforce the rules? Is it something else? I'm especially interested in examples, why you think they're good, and how long you've been involved.

Re:How Duterte Turned Facebook into a Weapon, with Help from Facebook on Saturday December 09, 2017 @12:01PM (#15886664)
Online communities need active human management and engagement. You can't automate yourself out of this, Facebook. It seems like this pattern is repeated over and over. Slashdot figured out a way to have human cultivation aided by software. And the result was high quality. Digg came along and tried to go all software, and it failed. Ignoring these lessons, many, many newspapers open up their articles to unfettered commenting and are shocked when anonymous users with no sense of accountability produce ugly comments.
Re:SpaceX raises another $100M on Monday November 27, 2017 @06:34PM (#15792787)
Is that a lot or a little? How am I supposed to judge? It looks like SpaceX is well over $1B with a B in funding in total now. In comparison Blue Origin just gets money from Bezos, so "no" funding?

Re:Ask HN: What service do you use for human translations of your webs... on Wednesday November 01, 2017 @10:38AM (#15601501)
I worked as a (very) part-time translator (Japanese to English) for a company called Gengo. It's a "shared economy" structure, with any army of freelancers doing the work. Good at smaller, quick translations. To be clear, I have no experience buying their service, and I haven't done any work with them for several years. https://en.wikipedia.org/wiki/Gengo
