Hey @SocialCoop braintrust, anybody know any #coop developers in Kentucky?

My wife was looking at the properties of #ellipses such as the one where the sum of the distance of all points on the #ellipse from the two foci are the same and how that relates to the standard equation of an ellipse. I wrote these notes up neatly using #LaTeX to explain the relationship.

To put it up here, I converted the #PostScript pages to #PNG format using #GNU #Gimp and the figure was produced using #Tgif.

Some impressive green-washing post from @EU_Commission here:

Would be good if scientists reacted here and on Twitter.

Some details below ⬇️

Opinion: Davos Was a Case Study in How Not to Talk About Climate Change
In emphasizing technological solutions, the elite are sidestepping their own responsibility for the climate crisis. - Jag Bhalla @ Undark: undark.org/2022/06/30/davos-wa

You probably heard of #OsmAnd, the swiss knife map app that uses #OpenStreetMap data, but do you know that there's a web-based interface, too?

Check out osmand.net/map, and plan your trips with routing, and various map rendering options, while doing so in the comfort of your desktop browser.

It even includes weather forecasts, if you're trying to avoid getting wet for your weekend ride.

You don't even need to register for an #OsmAnd, or #OpenStreetMap account to use it.

I remember, years back now, coming across someone arguing with fervor that proprietary software was better than open source software because it was more secure. It was a culture shock to me, because usually I am surrounded by people for whom the benefits of open-source software are self-evident. I got the same feeling today arguing with some folks who genuinely believe that being locked into a proprietary, centralized silo is actually better than having control over your own platform...

As usual, billionaires don't play on the same league, whatever you do, they can do worse (probably 500 times worse with each go, in this case).

Time to turn off your fitness trackers, USA-ians. If you've got a uterus and the fitness thing does core body temperature it's a decent predictor of ovulation and pregnancy :(

And, according to the interview, it only runs on platforms that lock those people with the disabilities into nasty proprietary software monocultures than, ironically, exist to remove their new-found freedoms from them. Sad. Easing suffering should not be profit driven 2/2
