Traffic flow simulated on 30 different kinds of 4-way junctions

Traffic flow simulated on 30 different kinds of 4-way junctions

Here’s a really fascinating animation and analysis of traffic flows with different intersection methodologies. More interesting is that they were done with off-the-shelf steam games/tools found on Steam. I think

Some interesting observations:

  • 4 way intersections with lights (235 cars/min) is only slightly better than a no light free-for-all (191 car/min)
  • Standard roundabouts with stops are really horrible, but get pretty interesting and good with a few simple improvements
  • There’s a lot of interesting junction/interchange types I’ve never seen before

Highest Form of Disagreement

Highest Form of Disagreement

Democracy is a contact sport. Everyone gets bruises. Even the winners. And the kind of bickering we see today is not only unproductive.
It’s cowardly.
If you don’t have the guts to focus on ideas and stop tearing down individuals, you belong in the stands, not on the field. I want more leaders who are brave enough to focus on ideas and not ad hominem attacks. I want more leaders who are willing to say, “I hate everything she stands for, but I do not hate her. And neither should you.”
And I want more Americans who demand these kinds of debates for the sake of our democracy. Just ideas against ideas, let them fight it out, and if you lose, come back with better ideas.
Are millions of Americans ready to start fighting fair for the sake of our democracy? For the sake of solving common problems we all face?

Oregon Coast Storm Surge

Oregon Coast Storm Surge

A reminder that the Oregon coast is one of the most deadly coastlines in the world.

The coast has been getting pounded by some huge waves in the last few days. 30 and even mammoth 60 foot waves have been recorded. One even crashed into a set of condos, some coastal buildings have been damaged, and at least 1 person has been swept out to sea and presumed dead at this point.

Here’s some video of the storm surge coming in. A reminder that sneaker waves and surges will toss 1000lb downed trees around like matchsticks and drag you or your car wherever they go.

Aliens: The Ride and How far we’ve come

Hin Nya constructed an incredible virtual roller coaster which incorporates the haunting visual and auditory elements of the Aliens films in an insane 15-minute-long ride, built with the theme park simulator app Planet Coaster. Headphones recommended.

Not long ago, it would have taken whole teams to put together an experience like this – what a world we live in.
