I have a new policy brief out on zoning for manufactured housing. I think that laws that are already on the books protecting manufactured housing as an option are somewhat under the radar: www.mercatus.org/research/pol...

BREAKING: SCOTUS denies the Trump administration’s request to enforce the new U.S. Postal Service rule for the 2026 elections. Justices Alito and Thomas dissent. More to come at Law Dork. www.lawdork.com
SUPREME COURT OF THE UNITED STATES
No. 26A305
UNITED STATES POSTAL SERVICE, ET AL. U.
CALIFORNIA, ET AL.
ON APPLICATION FOR STAY
[September 14, 2026]
The application for stay presented to JUSTICE JACKSON and by her referred to the Court is denied. The Government is unlikely to succeed on the merits of its challenge to the District Court's preliminary injunction. And the equitable factors applicable for obtaining emergency relief from this Court do not favor a stay.
JUSTICE KAVANAUGH, concurring.
In my view, based on the briefing the Court has received at this interim stage, there is at least a fair prospect that the final rule falls within the Postal Service's statutory authority. See 39 U. S. C. §401(2). But applying the rule in the 2026 elections would be arbitrary and capricious in violation of the Administrative Procedure Act because state and local election officials do not have sufficient time to reasonably implement the rule before the elections. See 39
U. S. C. §3001(m); 5 U. S. C. §706(2)(A). For that reason, I concur in the denial of the application for stay.

A lot of intra-Dem fighting is b/c factions are forced into competing in a single primary electorate. It'd be much healthier if it was openly a matter of each going out and winning its share of seats in accordance w/ its general election votes and then having an inter-party coalition shaped by that.

$20k–$40k per parking space is the cost Tempe developers bake into rents when the code forces them to build unnecessary parking near a light rail station. The Council can cut those requirements June 4.

I thing a lot of the frustration over Polis' clemency for Peters was simply this: Colorado saw the insurrectionists who were convicted being pardoned by Trump, but at least we could say, Colorado is different. We hold people accountable. Polis blew that up. It was insulting to our state pride.

Every LinkedIn post is either anodyne boosterism or shameless rage bait. “Quality assurance? Bah! We let our customers find our product flaws, and they love it!”
LinkedIn Post:

I exited a $150M company with zero unit tests.
(Somewhere, a TDD evangelist just screamed into a pillow.)
We didn't have automated testing.
No CI/CD pipeline.
We pushed straight to production.
We were doing $35M in ARR.
Meanwhile, the startup "doing it right":
95% test coverage
3-stage deployment flow
Every line of code gets a code review
Two-week sprint cycles
$O in revenue
Customers are the best testers you'll ever have.
They find edge cases your mocks never will.
They pay you while they do it.
