Congratulations to the Class of 2024! We’re expecting great things from you, unlike the Class of 2023, which we all knew was never going to amount to much.

With #RankedChoiceVoting in our presidential elections, neither major party would have to worry about 3rd-party candidates playing "spoiler." Voters would get more choices & a representative, majority winner.

@MPayneCville @CvilleBubble But wasn’t the point of the tents to get the police to come?

[Chris Hellings @alephthought]

@tjsleakyroof And then they could have taken them down this morning. Would have been no problem.

[Chris Hellings @alephthought]

@tjsleakyroof They were doing fine without the tents. I think the point of the tents was to get the police to come.

Take note of the people expressing more outrage today at police arresting trespassers than they did at Hamas brutally attacking Israel.

A new study of 350,000 European adults screened for genes and surveyed for lifestyle determined that, other than being blessed with good genes, the 4 best things you can do to live past 75yo are (listed by the rank of the size of the effect estimate):

1. Don't smoke.

2. 150 minutes moderate activity per week (or 75 minutes vigorous activity)

3. Sleep at least 7 hours a night.

4. Eat a healthy diet (more fruits and vegetables, less processed meats)

I think it's great that in the old days you wouldn't know about an eclipse until you suddenly see it and tremble that the gods have cursed you but now we can know ahead of time which regions will be cursed by the gods and the curse potency percentage

The iPhone camera uses computational photography, applying software to every snap.

This wild photo is an eery example: the subject tries on a wedding dress and each mirror shows her in a different pose.

Why? Apple insider says it’s a “mistake” in the computational photography pipeline:

➡️ “The iPhone camera doesn’t realize it was taking a photo of a mirror, so it treated the three versions of [UK actress Tessa Coates] as different people. Coates was moving when the photo was taken, so when the shutter was pressed, many differing images were captured in that instant. Apple's algorithm stitches the photos together, choosing the best versions for saturation, contrast, detail, and lack of blur.” ⬅️
