This is a recurring post to discuss programming or other technical projects that we've been working on. Tell us about one of your recent projects, either at work or personal projects. What's interesting about it? Are you having trouble with anything?

Please post your solutions in your own top-level comment. Here's a template you can copy-paste into your comment to format it nicely, with the code collapsed by default inside an expandable section with syntax highlighting (you can replace python with any of the "short names" listed in this page of supported languages):

This thread is posted weekly, and is intended as a place for more-casual discussion of the coronavirus and questions/updates that may not warrant their own dedicated topics. Tell us about what the situation is like where you live!

I know that a lot of people kick off a new calendar year pursuing new resolutions, new goals, and new interests. I figure this thread can be a way of helping people embark on their individual journeys using guidance those who are more in the know.

Ask about anything you're wanting to start or dive into: listening to a new band, starting a new fitness routine, diving into Discworld, making a game, etc.

So, I just listened to a This American Life podcast called Ghost in the Machine. In one of the stories, a man decides to calculate, every week, the Average Family Location of his family. By that, he means: once you add everyone's coordinates for every coordinate in which they've been in that period, what city/location represents the average point between them all?

I decided to do the same for my family, which will be much easier because there are no touring musicians among us. The one complication is that a good chunk of the family is on other continents, and I wouldn't want us to "meet" in the middle of the ocean. So some approximation might be warranted.

I'd be happy if someone could provide me the math, I'm fairly confident I would be able to do it with a calculator or maybe put into some crude Python. I don't think I need to make a weekly report, since we're not that mobile. Maybe twice a year, or once every two months.

Thanks!

Edit: I don't know much math

Edit2: holy shit this is not simple at all! Now I feel kinda bad for throwing this problem at you guys. I really thought it would be quick and easy!

This thread is posted weekly - please try to post all relevant US political content in here, such as news, updates, opinion articles, etc. Extremely significant events may warrant a separate topic, but almost all should be posted in here.

This is an inherently political thread; please try to avoid antagonistic arguments and bickering matches. Comment threads that devolve into unproductive arguments may be removed so that the overall topic is able to continue.

What have you been listening to this week? You don't need to do a 6000 word review if you don't want to, but please write something! If you've just picked up some music, please update on that as well, we'd love to see your hauls :)

Feel free to give recs or discuss anything about each others' listening habits.

You can make a chart if you use last.fm:

As part of a weekly series, these topics are a place for users to casually discuss the things they did — or didn't do — during their week. Did you accomplish any goals? Suffer a failure? Do nothing at all? Tell us about it!

What is a "Screenless Day"?

Tildes "Screenless Day" is a simple event aimed at encouraging people to take a temporary step away from toxic or consuming aspects of technology and spend their time and energies elsewhere.

When is it?

It takes place over the weekend starting on the first Friday of each month. Participants will choose that Friday, Saturday, or Sunday to take as their screenless day -- whichever works best for their schedule.

Some people might not be able to participate in that window, and that's fine too. They can choose to shift their day earlier or later as needed. It is also completely fine (and encouraged!) to take personal screenless days separate from the event if you like. This thread will be posted the first weekend of each month, but it is open for comments the entire month.

Does it have to be truly "screenless"?

"Screenless" is an ideal, not a mandate. The spirit of the day is to deliberately step away from toxic or consuming aspects of technology, and what that means is different for each person. Thus, it is up to each participant to determine what "screenless" means to them. Some might only choose to not use social media for a day; some might choose to eliminate all "screens" but still use their ereader; some may maintain some screen use but only for necessity (e.g. work; classes; GPS; etc.). Some might get rid of screens entirely, or go fully "unplugged" for the day.

How do I participate?

You do not have to do anything formal at all to participate -- simply take your screenless day in whatever way is best for you!

If you’d like to, use this thread to share plans for your upcoming screenless day or summaries/reflections about it once it’s over.

Can I chat in this thread if I'm not participating?

Yes! The more, the merrier! Discussion from anyone, participant or non-participant alike, is welcome. Though, do understand that it might take a bit longer than normal for some people to respond. :)
