Make sure you read the report about how Stephen Miller deported Waco's favorite Mexican restaurant owner.

Newark mayor Ras Baraka's administration is proposing downzoning some parts of the city back to R-1 single-family zoning:

“Car inspectors tell Yle that the root cause of the problem is that EVs are often built on platforms that do not sufficiently support the weight of the car, including the battery, and the wear and tear of the structures over time.”

Gonna be thinking about this lede for a minute.
(RNS) — Last month, the Rev. David Black stood in front of a Chicago-area U.S. Immigration and Customs Enforcement facility and spread his arms wide. Adorned in all black and wearing a clerical collar, the pastor looked up at a group of masked, heavily armed ICE agents on the roof and began to pray.

“I invited them to repentance,” Black, a minister in the Presbyterian Church (USA), said in an interview. “I basically offered an altar call. I invited them to come and receive that salvation, and be part of the kingdom that is coming.”

But when Black began to lower his arms a few seconds later, the agents responded to his spiritual plea by firing pepper balls, or chemical agents that cause eye irritation and respiratory distress, video footage shows. One struck Black in the head, exploding into a puff of white pepper smoke and forcing him to his knees. Fellow demonstrators rushed to his aid, and as the pastor rubbed his face in pain, the agents continued to fire.

“We could hear them laughing,” Black said.

The guy blowing the trumpet (lol) makes me suspect there’s a bit more to it than that, but, there is also clearly a train with passengers on it passing through a station whose platform does not have a proper floor, which is not something I’ve ever seen in NYC at least.

A few people have asked, so: yes, comments from the general public are welcome! The email address was created for that. If you have technical comments, great. If you just want to register nonspecific support or opposition to changes, that’s helpful too.

Is a two-month shutdown necessary? I was watching a TikTok of the platforms on the M13 being rebuilt ahead of GoA4 upgrades, and they were pouring concrete with a basic metal and mesh barrier and the trains still running. It made me wonder if we go overkill with this stuff. @a320lga.bsky.social
Quelques fermetures mais c’est pour la bonne cause ! On vous dit tout 🚇 #ratp #ratpsansfiltre

So the argument always has to be “I am establishing X risk, and Y risk is equivalent, so you should accept Y.” This is going to look pretty similar to “You don’t like Y, so we should fix X risk.” But that’s not what I’m saying!

I think building code reform is often going to make you nervous, because there is no stated acceptable level of risk, so to argue for changes, you have to identify a risk in the existing code and then prove that you’re not proposing to exceed it

The “if you give a mouse a cookie” ramifications of sprinklers are very understudied…

And that two-thirds-or-90% number is primarily based on 13R and 13 systems in commercial and multifamily occupancies – not 13D ones in single-family occupancies with larger smoke compartments. AND it doesn’t correct *at all* for other building features of occupant socioeconomics. It’s VERY suspect.

**applies a proprietary adjustment to the data
stephenjacobsmith.com
It’s about a two-thirds decrease according to the raw NFIRS data. NFPA then applies proprietary and adjustment to the data to arrive at the 90% figure that gets cited, and they will not share the details of how they do that.

But to a much lower standard than the 13/13R systems in multifam…no monitoring or supervision. I am skeptical that new single-family houses in California have fire death rates as low as new multifam, since they have more occupants per smoke compartment.

Caltrans has released a cross section for the ultimate (raised viaduct) version of SR-37.

Now maybe I'm just being paranoid, but if you were building a road that you planned to keep at 4 lanes wide, I don't think it would look like this.
Cross section of 114' wide bridge structure with each direction having a 12' outside shoulder and a 10' inside shoulder.

It’s not risk aversion though, it’s bias against apartments. America accepts more health and life safety risks in its built environment than any high-income country on earth.

It will be tough to get very far with building code reform without calling out what’s going on though. We are killing people and making urban housing unaffordable because of this basic failure to see the big picture.

The extreme nannystatism towards apartments has a glaring loophole that most Americans – including most firefighters, building officials, and fire protection engineers – exploit: live in a house! Even where sprinklers are required in new houses (California), most live in old houses without them
stephenjacobsmith.com
Given all the features (like sprinklers – not common abroad) that we've loaded apartments up with, I doubt fire risk would increase by allowing very small footprint buildings to have a single exit. But this data raises a bigger question: are we too intolerant of more genuine fire risk in apartments?
stephenjacobsmith.com
I can't stop thinking about this. We're pursuing zero fire risk in multifam, while tolerating much more in single-fam. People respond by building and living in single-fam, where they're exposed to not only one of the highest fire death risks in the developed world, but also TONS more car crash risk

Love this new report on buildings' relative fire safety from @alexhrwtz.bsky.social and Pew colleagues.

Oh wait no, he’s the dumb-looking one on the other side, phew 😅

Please don’t tell me he’s the hot one. I won’t be able to handle that information.

This is what Americans graduate to when they decide they wanna be fancier than dumping a can of jarred sauce into a pot of strained pasta

I wonder if they’re especially receptive here because they perceive these as commercial and not personal vehicles (honestly kinda strange that a business would risk this? seems like a lot of effort and risk for something that makes you money)
