TIL @t-online.de rejects emails if your server does not have a mailing address listed.

We already have DMARC, DKIM, etc., and idiotic requirements like this make it harder and harder for regular people to use their own email servers.

The US now officially stopped honoring the human right to asylum. This is a bitter day for people fleeing war, hunger, or oppression.
US will limit number of refugees to 7,500 and give priority to white South Africans
Low number represents a dramatic drop after US previously allowed in hundreds of thousands of people fleeing war and persecution

Downtown and West Oakland can provide housing close to major commercial hubs and transit.
Removing this freeway will not only undo some of the damage done to the West Oakland community, but make space for a lot of affordable housing, reduce air/noise pollution, and provide new green spaces.
Caltrans is presenting on their preliminary findings for Vision 980 at the 10/16 BPAC.

The initial findings show that both the technical and community feedback planning processes support removal of 980 for a complete street, housing and parks.

I guess nobody told them that trains have Wifi and Tables. You can already work on your commute without endangering others.

I don’t think anyone is prepared for what they just did w/ ICE.

This is not a simple budget increase. It is an explosion - making ICE bigger than the FBI, US Bureau of Prisons, DEA,& others combined.

It is setting up to make what’s happening now look like child’s play. And people are disappearing.

Not even left-wing media is talking enough about how incredible stupid ripping up the #Iran nuclear agreement was.

Three things made the US a rich and powerful nation: the rule of law, its science & innovation system, and openness to foreign talent. Remarkable how Trump has taken a sledgehammer to all three. No enemy of this country could do more.

I realize I’m just shouting into the wind here, but: please, please, please stop posting screenshots without links, or summarizing breaking news events without links. There’s a serious problem with unsourced assertions all over the world right now, don’t be part of the problem.

Sprawl “solves” the housing crisis by turning it into a transportation crisis.
Not a single time in this article glorifying the need for sprawl to address the US's affordable housing crisis is there a mention of the vast transportation costs of sprawling living patterns. Nor is there mention of the fact that sprawl is directly linked to disinvestment in urban cores.
America Needs More Sprawl to Fix Its Housing Crisis
The word has become an epithet for garish, reckless growth — but to fix the housing crisis, the country needs more of it.

I am so glad Chuck Schumer gave up all the oppositions leverage and voted for that budget resolution, because things would be equally bad right now if he had.

The administration is making the case that non-citizens don’t get due process. That is the same as saying citizens don’t get due process.

Without due process, you are not a citizen if the government says so.
