Whatever the expectations for the July 7-8 NATO summit in Ankara, Turkey,
the geopolitical situation favors Turkish President Recep Tayyip Erdogan so heavily that he is all but guaranteed to emerge the winner
—if NATO summits can have winners at all.
In the wake of the disastrous Iran war,
both the timing and the venue are highly auspicious.
Donald Trump told reporters that he was coming to Ankara solely for Erdogan
—another small, symbolic victory.

What is a sanguine new congressional candidate to do
when the district they thought they were running in gets torn apart by a governor’s efforts to gerrymander his state at the president’s behest?
For Pia Dandiya, a first-time candidate for the Democratic party in Florida,
the answer was simple:
pick up some maps, hit the road, and embrace the challenge of conquering a different part of the state.
Dandiya, a professional educator dipping her toe for the first ti…
I had a weird dream where I was talking to someone at some kind of ceremony, I think a funeral, where I had timidly painted my face with clay as part of some ritual. This person was talking about how far society has come while our brains have not caught up.
Imagine if your ancient cave dwelling ancestors were dropped into this world of cars, office hours, budgets, climate change, and AI. They would be absolutely freaking out and struggling to understand things all the time... Just like you are now.
Society teaches us to suppress these emotions. You're supposed to be OK with giant metal boxes flying around you in rumbling stampedes, but you feel it in unexplained anxiety. You're supposed to just fit your life into tight little bounds that ignore weather and season, but you feel it in more unexplained anxiety and depression. We are all part of something so big and complicated we can't make sense of it, we cannot possibly comprehend it all, it is simply too much to fully grasp the implications of our individual actions within global capitalism. Should we be surprised by our urge to simply destroy it, by the anger and desire to simply "smash" something far more complex than can be met with simple violence?
Some part of my brain was trying to remind me to be compassionate to myself. Perhaps that reminder can be useful to you as well.
Non-uniqueness of geodesic limits and a question of Grayson and Gage

Abstract: Grayson and Gage proved that an immortal curve shortening flow of simple closed curves on a closed surface converges subsequentially to a closed geodesic, and they asked whether this limiting geodesic is unique. We answer this question negatively by constructing a smooth Riemannian metric on $\mathbb{S}^2$ and an immortal simple closed curve shortening flow that converges along different sequences of times to every geodesic in a one-parameter family of distinct simple closed geodesics.

A/I had scale. They managed lots of things, so they could have lots of people working together. This is critical to maintaining secure infrastructure. It simply takes a lot of people to do the work.
You have to be able to patch fast, which means you need someone on a pager able to take work on a weekend. This kind of thing destroys people unless you have at least 4-6 people just on patch duty.
That doesn't count other maintenance, security analysis, customer support, etc. This is a *huge* amount of work.
Tech scales up well, and down poorly. But insurgency becomes the easiest to stop when it's scaled and centralized.
An answer to this problem is "federation." Informal federations, or even formal federations that focus on shared infrastructure and separate management can solve the scaling problem without creating an easy legal target....

On Tuesday, Michigan Democrats will answer a simple question:
What if we support passion and change over safety?
The answer could reverberate through the party for years.
