And on my musical side... Really flattered by this review of my newly released EP with Kimberly Collins. I think the reviewer really got what we were going for with these songs. www.unxigned.com/reviews/ep-r...

When Republicans are pre-butting a pro-democracy rally like No Kings and making shit up left and right to scare people, you know they're losing and in panic mode.

I just realized that Octavia Butler's classic novel "The Parable of the Sower" takes place way off in the future... in 2025.

I'm a psychologist. I know this test. It isn't hard unless you have cognitive deficit. The vast majority of people get a perfect score. I don't understand why the media don't call this out.

This right here is Trump's ultimate goal: staying in power

Pritzker: "He wants to militarize major cities because he wants us to get used to the idea of troops on the streets. I believe he's gonna post people outside of polling places and if he needs to in order to control those elections, he'll assume control of the ballot boxes & count the votes himself"

The more Trump tears things down — especially on public health & science — the more California will step up to take care of business at the state level. Trump is destroying the CDC & making it harder for people to get vaccines. So California is picking up the slack — now moving toward our own CDC!

Gypsies, tramps, and thieves
We'd hear it from the people of the town
They'd call us gypsies, tramps, and thieves
But every night all the men would come around
And lay their money down

Last week, Boston received a letter from AG Bondi threatening to prosecute officials and withhold funds unless we cooperate with carrying out mass deportations.

The US Attorney General asked for a response by today, so here it is: stop attacking our cities to hide your administration’s failures.

Yup, if you search google scholar for vection you'll find research about it. It also works in car washes where your car sits still and the large brushes all move in one direction. Astronauts apparently suffer from the illusion a lot.

🚨 150 University of California law professors (and counting) have now signed this open letter to the UC Regents and other officials, explaining the flagrant illegality of the Trump Administration’s UCLA funding cut offs, and urging the UC to fight back. sites.google.com/view/uclawfa...

Dear President Milliken, Regents, and Governor Newsom,
As faculty members of University of California law schools, we endorse Governor Newsom's commitment to resist the Trump Administration's unlawful actions taken against the University of California, Los Angeles. The Governor is on firm legal ground. The Trump Administration's termination and suspension of federal funds has violated Title VI of the Civil Rights Act of 1964 in numerous ways. Governor Newsom and the University of California Regents will protect the vital interests not only of Californians but of all Americans if they defend the University of California's rights.
The U.S. Department of Justice notified UCLA on July 29, 2025, that it had found that UCLA had "violated its obligations under the Equal Protection Clause of the Fourteenth Amendment and Title VI of the Civil Rights Act of 1964." Chancellor Frenk subsequently announced that
"the federal government claims antisemitism and bias as the reasons" for federal grant terminations. UCLA faces losses of at least $584 million, funding that has supported vital research on matters ranging from treatments for pancreatic cancer to advances in online security.
The Trump Administration has made no pretense of following the law. Title VI permits a federal agency to terminate funding only if it has found that the particular program receiving that funding has violated the law's non-discrimination provisions. Funding cannot disappear just because the agency's policy or political preferences differ from the institution's.
Moreover, the agency can act only after following specific procedural steps. Importantly, Title VI requires a formal administrative hearing—a proceeding much like a trial-before the agency can terminate funding. At the hearing, the agency would have the burden of proving the university's alleged violations of Title VI before an impartial decision-maker. If the agency prevails at the hearing, the university or other interested persons could appea…

factually supported and consistent with civil rights laws. Without the steps Title VI requires, there is no protection against an administration alleging discrimination as a pretext to force compliance with its policy or partisan preferences. Title VI's procedures guarantee the constitutional due process requirement that no person can be deprived of liberty or property without fair notice and opportunity to be heard. They protect the university and its members' academic freedom, an endowment essential to scientific research, intellectual discovery, and open debate.
We are deeply committed to the core principle of non-discrimination codified in Title VI and in the Constitution's Equal Protection Clause. The principle that no person may suffer discrimination because of race, color, or national origin protects equality and ensures fairness in political as well as social life. Allegations of discrimination deserve serious and careful consideration and, where established, effective redress. But this enforcement effort must follow the law.
We urge Governor Newsom and the UC Regents to continue to stand up for the fundamental principles of the rule of law, due process, and equal protection. A defense of the University of California's rights in court will model respect for these bedrock principles of equality and fairness, and it will ensure that the government honors them. The Trump Administration's failure to abide by the law subverts these principles by denying the University of California a fair opportunity to contest the government's charges of unlawful discrimination before an impartial decisionmaker. It is precisely because we cherish the principles of the Civil Rights Act and the Constitution that we encourage Governor Newsom, the UC Regents, and the University of California to fight back.
Through its grantmaking powers, the federal government wields vast influence over social and economic life. If not held to account by the procedural protections enacted by Congres…
