NEW: We just joined more than 200 organizations condemning President Trump’s dangerous threats to commit war crimes and grave atrocities in Iran.

Our leaders must follow the Constitution and international law and urgently act to stop any targeting of civilians by this administration.

YOU: Hi my name is [name]. I’m calling from [ZIP CODE].

YOU: Today, President Trump said that “a whole civilization will die tonight” if Iran does not meet his deadline to reopen the Strait of Hormuz. That rhetoric is extreme, dangerous, and disqualifying.  

FOR THOSE W/ DEM ELECTEDS: I’m asking [ELECTED OFFICIAL] to publicly condemn this rhetoric and use every available procedural tool to stop further escalation, including support for impeachment and urgent public pressure on congressional leadership.

FOR THOSE W/ GOP ELECTEDS: I’m asking [ELECTED OFFICIAL] to publicly condemn this rhetoric, press the administration and cabinet to treat this as disqualifying conduct. 

YOU: Calling this what it is matters. Even if removal is difficult, elected officials should treat rhetoric like this as unfit and dangerous.

YOU: [OPTIONAL COMMENTS]

Screenshot of a tweet by Rep. Ted Lieu stating that U.S. military law prohibits war crimes, including strikes on civilian infrastructure that cause disproportionate harm. The tweet warns that service members must disobey illegal orders and could face prosecution by a future administration if they commit war crimes.

People do offer food and drink as per normal customs to people wearing masks.

Once or twice is normal.

Five times in under two hours is someone that is applying pressure.

An Experimental Port of SageMath to Browser via WebAssembly (v86)

Not just in the long term.

Consider the #WebAssembly port discussed in #SageMath (groups.google.com/g/sage-devel...) – so many packages not ported yet, it's just not actionable except by CPU emulation (v86).

Meanwhile I'm already shipping @passagemath.org packages on @prefix.dev emscripten-forge.

It’s International Long Covid Awareness Day.

One of the best things you can do to support people with Long Covid is wear a mask (ideally a respirator like an N95).

Masks break chains of transmission.

They prevent infection.

The only way to avoid Long Covid is to avoid Covid!

Long-COVID Sufferer Awarded Nearly $1M After Employer Refused to Let Her Work From Home | Law.com A jury in Nassau County awarded $954,000 to a longtime employee of Stony Brook University Hospital Blood Bank.

A woman with Long Covid won almost one million dollars in a lawsuit against her employer who refused to allow her work from home accommodations.

May this set a precedent.

Remote work should be accessible to all who need it.

It’s a game changer for people with disabilities.
