I updated calendar-mcp so it now handles http-based ICS calendar feeds, and ICS info in a json file (from Power Automate for example). So it can now see my work calendar, conference calendars, etc. along with my regular calendars and email accounts.

Watch closely: Donald Trump is plotting to rig the midterms.
In just the past 2 weeks, his AG demanded that Minnesota turn over voter rolls, his DNI raided 2020 election ballots in Georgia, & he called to 'nationalize' our elections.
We must mobilize to protect our democracy.

This #ai stuff is hard to keep up with. About a week ago I started using #get-shit-done with #claudecode. Now I'm trying #vscode #copilot again, and they've made _major_ enhancements. In a week!
Same with #claude in #excel - quickly followed by #copilot in #excel, that does much the same thing!

Do you believe Trump or what you see with your own eyes? He says economy is good, but you know prices are up. He says ICE is doing well, but we watch them murder Americans. He says he has nothing to hide w/ Epstein, but he still won't release the files.

The people of Minnesota have executed one of the most impressive civil resistance campaigns I can remember:

- Maintained nonviolent discipline amidst violence
- Mobilized 10,000s in subzero temps to protest and watch ICE

Reports that ICE grabbed a legal resident with of Minnesota with no criminal history and his five year old child off the driveway to their own home and whisked them away to another state are extremely disturbing. Also disturbing: the VPOTUS appears to not understand what is at issue in this case.

I just spoke with the White House after another horrific shooting by federal agents this morning. Minnesota has had it. This is sickening.
The President must end this operation. Pull the thousands of violent, untrained officers out of Minnesota. Now.

There’s a clear pattern to how Trump has long been building toward the Insurrection Act. He isn’t “unhinged”—his horrid responses to ICE shootings, assassinations, and mass killings are by design. National traumas are his ammo. I document his method here 👉🏻 www.motherjones.com/politics/202...
