This is a really nice presentation of the efficiency challenges of reverse-mode AD!

Interesting how discussions about how the iPhone Air should/must have at least two cameras to be a compelling product differ so evenly as to whether the second camera should be wider or narrower (zoom).

This is a great interview. I really appreciate that despite the superficial bluntness of the term he's now famous for, Doctorow tries to highlight nuance and acknowledge universal human weaknesses.

Woof, trying out a tutorial and it has all these nice steps for using hosted notebooks. Here's where we install the dependencies... but the tutorial is several months old and so the dependencies don't actually install properly and I guess that's the end of that.

Figure's new humanoid #robot looks really impressive. It'll be really interesting to see if palm cameras and a little bit of tactile sensing in finger tips is enough for consistent performance in delicate manipulation tasks. www.figure.ai/news/introdu...

The anti-anti-AI rhetoric in my feeds has reached a pitch that circles back around to demonization and conspiracies. I find memes like this to be a useful touchstone: you often have both banal interactions and insidious trends and influences at the same time.

A question for folks who have felt the weight of the yoke of Jira: is it that you could make a better Jira, or is it that Jira reflects and amplifies certain management ideas to a point of self-injury?

Whenever I bump into Passkeys I'm reminded of how bad an impression that entire technology made by promoting a model that would further lock you into a big tech co’s ecosystem. Not only did the tech itself burn its credibility, but I lost trust in commentators recommending them, too.

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN.
It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package.
Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats
