This is your annual reminder that Math.abs(Integer.MIN_VALUE) == Integer.MIN_VALUE, which is negative. Also, Integer.MAX_VALUE is prime. Finally, I'm leaving this hellsite for Bluesky (same userid) because many of my favorite tweeters went there, and you go where the action is.

If only this could’ve been foreseen!

“Democracy is the theory that the common people know what they want and deserve to get it good and hard.” ― H.L. Mencken, A Little Book In C Major (1916)

A Trump-appointed judge just struck down a Biden rule expanding overtime pay to 4 million working people. It's really surprising how little media coverage this has received. Trump faced no real questions about this issue during the campaign. 1/ (link) newrepublic.com/article/188663…



As relevant today as the day it was written, and as beautiful. Let us hope that we have a competent leader again someday, and that they can undo some of the damage the our president-elect has done in the past and will do in the future.


Poor babies. He's doing exactly what he said he was going to do. Perhaps they should not have voted for him. npr.org/2024/11/17/nx-…


“Democracy never lasts long. It soon wastes, exhausts, and murders itself. There never was a democracy yet that did not commit suicide.” ― John Adams, Letter to John Taylor (1814)


“Totalitarianism in power invariably replaces all first-rate talents, regardless of their sympathies, with those crackpots and fools whose lack of intelligence and creativity is still the best guarantee of their loyalty.” ― Hannah Arendt, The Origins of Totalitarianism (1951)


This was entirely predictable. Trump (a twice-impeached convicted felon and adjudicated rapist) should never have been eligible to run. Our institutions have failed us.

This makes about as much sense as choosing me to be the head coach of the Pittsburgh Steelers. politico.com/news/2024/11/1…


This hellsite (the platform formerly known as Twitter) bitches at you if you don't have two-factor authentication set up and then tries to make you pay them to enable it. I have never seen 𝘢𝘯𝘺 other website engage in this malodorous behavior.

Color me shocked.

From Ipsos last month. People who answered factual questions about inflation, crime, and immigration incorrectly were "more likely to opt for Trump," while those who answered correctly preferred Harris. Disinformation and lack of basic education and knowledge are destroying us.

In 2014, Tim and I went to the 25th Anniversary Miata Reunion, and got Bob Hall, Mark Jordan, and Norm Garret to sign the first ever (1989) Miata brochure. Unfortunately, we missed Tom Matano. Cindy and I rectified the matter yesterday.

I do not understand why the Harris campaign has made a bigger point of this. They're letting the opposition get away with saying they'd be better for the economy.

Trump, overnight: “If Kamala wins, you are 3 days away from the start of a 1929-style economic depression.” What has happened since the last time he predicted a depression if a Democrat won:
