l've been a SA advocate for decades:
NEVER go to campus resources for a SA. Call a rape care hotline/program (off campus), get a SA advocate (they're free), go to a SART hospital for care (and evidence collection if you choose).
They activate the police. Schools have NO business in this process and will minimize and bury it. It's a criminal matter, not an administrative matter.
Period. No exceptions.

Because they know what is real and proper. A custard is made from milk, egg yokes, and cream. That's it. "Creme" or "Kreme" is made from corn syrup, modified food starch, potassium sorbate/sodium benzoate, water and sugar because it has a long shelf life, and cheaper to make.

Hummingbirds.
A four panel comic. In panel 1, a rufous hummingbird flies down toward a large hummingbird feeder with as many as 6 holes on top. He thinks "The humans put up a new feeder!" In panel 2, he lands on the feeder and gazes down at it. He thinks "It's huge. Many of us could feed here at once." In panel 3, we see a close up view of the hummingbird, and he's thinking "This could end the ancient rivalries. Usher in an era of peace. Interesting." In panel 4, an Anna's hummingbird hovers over the feeder and says "Hey, can I have some necta-" and the rufous hummingbird says "No."

Look at this graph. The share of national income going to the richest 10 percent was lowest (and share to lower 90 percent highest) when union membership was at its highest. As unions have weakened, inequality has widened. This is why we must build back union power.

Very important concept. An additional reason why the WHCA dinner was grotesque and the harms of journalists and news orgs normalizing and democracy-washing the fascist MAGA movement From our pro-democracy election coverage recommendations:
Journalists can defend democracy.
Make threats to democracy clear!
• Inform voters of the freedoms they will lose if the
MAGA movement wins.
• Abandon false equivalence between traditional and fascistic candidates.
• Expose candidates who foment political violence.
• Call out lies and bad behavior in every piece of reporting.
• Prominently cover the Big Lie-fueled attack on election legitimacy and voting rights.
We're demanding that newsrooms improve their 2024 election coverage:

If you're even a _tiny_ bit into security and privacy, pay attention to this one. A court filing in a case against cyberhacker Peter Stokes revealed Microsoft's GDID embedded in EVERY Win11 install provided the FBI the ability to trace his PC across VPNs(!!) & proxies(!!) across three countries.
windowslatest.com
Microsoft admits Windows 11 has a GDID tracker with no off switch, first documented publicly in an FBI hacker complaint
GDID is the persistent Windows ID that helped FBI trace a Scattered Spider hacker despite VPNs. Here's how it works and how to limit it.

Trump's $4 billion Presidential windfall is unprecedented in scale & source. Obama's wealth grew from royalties from books written before office, and Bush's largely came from a sports‑team stake from over a decade prior. Trump's new billions are from deals made in office.
