A genetic algorithm learns to draw a hummingbird:

The video is an animation of three thousand generations of evolution. It starts with a random mix of line segments which are then mutated by adding or removing lines and by changing the start, end and color of existing lines. Each generation has 32 individuals. The best individual is mutated to create the next generation.

For this implementation the best or fittest individual is the one with the least error on a pixel by pixel comparison to a stock art drawing of a hummingbird. Because I care more about the shape than completely filling in the drawing an error outside the figure is penalized three times more than a gap inside the figure.

Color is mutated each generation but not selected for, so it's just changing randomly.

910 days ago I vented my frustration at Windows 10 notifications.

Well someone in Redmond must be listening. They 'fixed' it.

The problem was that dismissing a notification did not actually get rid of it. Clicking the little x in the corner just sent it to the Action Center where you could enjoy reading it and dismissing it again.

Like some kind of cargo cult Toyota, Microsoft asked the one why, and changed the little x to an arrow. Now it's more obvious that you're just shuffling the notification around the desktop. Ticket closed. But I still have to handle every fucking notification twice.

Which makes the announcement of the April 2018 Update especially ironic:

"With this update, available as a free download today, you get new experiences that help minimize distractions and make the most of every moment by saving you time. Our hope is that you’ll have more time to do what matters most to you whether that’s to create, play, work, or simply do what you love."

I'm guessing they're all on Macs?

Not only does it know when you're home but the Nest Learning Thermostat also knows when you're nearby. Here's how it works.

You crank up the heat to 70 and walk away. Nest then immediately returns to 62 degrees.

Thinking there must be something screwy with the algorithm you turn it back up to 70. Nest knows that it's in trouble so it displays a comforting message like 'Heat set until 10pm', waits for you to leave and then sets the temperature back to 62 degrees.

Giving up on the learning part you use the app to manually program it to keep the heat on. Nest now uses its WiFi connection to phone the gas company and disconnect your service.

At BGR Chris Smith writes about Google's prodigious data collection:

"But that doesn’t change the fact that Google collects an incredible amount of data about you, especially from that device you use most, your Android phone"

And so I was amused as a Google Fi subscriber on a Pixel XL running Google Chrome and signed into my Google Account that the ad in the middle of the article was for Project Fi. If Google can't help paying BGR under these set of circumstances then we're some way off from the adtech singularity.

I'm hoping that a chat banner notification is for really great chats only and not some subtle distinction between chat notification types that I can't figure out even after some moderate to heavy googling. If anyone knows seriously please tell me.

Four Painted Lady butterflies eclose (emerge) from their chrysalises. The video has a timelapse and then realtime video of each butterfly in turn.
