★ Retraction: The App Store Rejection of the Week That Was, in Fact, a Correct Rejection

Yesterday I published an article titled “App Store Rejection of the Week: Dark Hours”. I have retracted it. Its premise was so fundamentally wrong that there’s no point merely correcting or editing it. Even the title, as I explain below, was inaccurate. Although the original...

Quoting John Gruber

Me, I try to get into the mindset of playing live music, not recording a studio album. Except when I’m writing a piece where I really want it to be an album. Those aren’t rare, per se, but they’re occasional. If I tried to make every post a hall-of-famer I’d never get anything out.

I’m aiming for professionalism. I’m performing live in front of an audience — not just jamming in my garage or bedroom, fucking around. So I’m careful and concentrate. I want to hit every note, in time. But at my best I’m moving from song to song.

Colossal Biosciences Said It Cloned Red Wolves. Is It for Real?

"The red wolf has long been a contentious species. The debate over its preservation got even messier last year, when Colossal said it had cloned the animal."
