Zohran for New York City

Zohran for New York City

Short read on the visual style of Mamdani's campaign — www.hollywoodreporter.com/news/politic...

An advert for a company called Magibook. The headline reads "Turn HARD books into EASY books with Magibook! Maximize your reading potential and avoid difficult language today."

Underneath is two covers of The Great Gatsby by F. Scott Fitzgerald. 

Above the first cover is the original version of the opening sentence (captioned "Turn Hard Books"), which reads "In my younger and more vulnerable years my father gave me some advice that I've been turning over in my mind ever since."

Above the second cover (captioned "into Easy Books") is a simplified version, which reads "When I was young, my dad told me something that I still think about."

THE BELL JAR

HARD ❌

It was a queer, sultry summer, the summer they electrocuted the Rosenbergs, and I didn't know what I was doing in New York

EASY ✅

That summer was sizzling, and so were the Rosenbergs

Why don't cargo ships use the Rust programing language?

Because they only know how to operate at C-level.

I think programmers **NOT** using #Emacs and #Vim are way more productive overall, as they don't spend half their time tweaking their editor/IDE configuration.

Keynote presentation by Hal Abelson and Gerald Sussman at the fourteenth RacketCon YouTube video by Racket

Profs. Abelson and Sussman spoke at RacketCon 3 months ago, "celebrating 40 years of magic": youtu.be/_2qXIDO-cWw ... wonderful, glad I finally got around to this.

They were given lovely gifts at the end of it, but it looked like neither of them recognized that tune.

A tweet posted by transphobe J*sse S*ngal which says:

"I don't know what else to say at this point other than that this whole thing has been incredible. I had no idea it would be like this. I thought a few people would complain and then it would be normal.

Gonna be a very fun BARPod segment."

His tweet contains a screenshot of @nacl.sh saying they are putting together an open letter to address S*ngal's violations of the Bluesky ToS.

The screenshot includes a reply "I intent to sign" written by Katie Tightpussy, Editor-in-Chief (@katie.bzky.team)

Very funny that S*ngal thinks that "Katie Tightpussy" is actually the Editor-in-Chief of Bluesky @katie.bzky.team .

Just incredible journalism to not be able to spot the difference between bzky.team and bsky.team

AWS Lambda turns 10: A rare look at the doc that started it On AWS Lambda's 10th anniversary, I'm publishing the internal PR/FAQ that helped launch this groundbreaking service. This document provides insight into the customer problems we observed in the early ...

“So today, on Lambda’s tenth anniversary, I’d like to share the PR/FAQ that launched one of AWS’s foundational services” says @werner.social — www.allthingsdistributed.com/2024/11/aws-...

Really detailed in the FAQ part. Amazing if this was the first document ever written on the topic internally.

But in 24.4, released 10 years ago in 2014, M-SPC was bound to cycle-spacing ... which obviates the need for delete-horizontal-space and also delete-blank-lines (which I don't use).

More weirdness I'm learning today, M-SPC used to be bound to just-one-space, and M-\ was delete-horizontal-space. My fingers knew the keys, I'd forgotten the names of the commands long ago.

Reminds me of how 25 years ago, I was twiddling my thumbs waiting for a web page to load and someone pointed out to me that I could open another Internet Explorer window ... multiple windows of the same program; it was magic! This was pre-tabs.

This isn't that big. But, is close.

#Emacs has a keyboard macro ring! You can cycle through all the macros you've defined! Wow, all those times I re-defined some complicated macro because I didn't want to figure out how to name it. Yikes.
