Melrose is in an alluvial plain and crosses multiple seasonal waterways. Water Always Wins (and Uplift Melrose depaving could have alleviated the severity of this event)

Pumping Hydrogen into methane gas pipelines is dangerous, too.
We should not allow it
@californiapuc.bsky.social should never have let gas utilities propose pumping hydrogen into gas pipelines in the first place. Its a costly ineffectual boondoggle that distracts focus from helping communities realize the health and safety benefits of electrification.

Contributor: Blending hydrogen into gas pipelines would enrich utilities and harm Californians
Experiments with natural gas pipelines are only a stalling tactic and profit grab that will prolong pollution. The real solution is to go electric.

Jane Ganahl's granddaughter doesn't eat animals and is fine with gay marriage. To some, this looks like indoctrination -- and Ganahl is fine with that.
Is it indoctrination to teach my granddaughter to have empathy?
If so, I’m fine with it. As a lifelong Californian, I’m acutely aware that my common-sense and compassionate life lessons could be viewed as wacko left-wing brainwashing by many.

Every time Jim Jordan releases a report, he leaves personal info exposed:
✔️my home address
✔️the names of undergraduate researchers
✔️and most recently members EU civil society

Tech companies get their employees' info shielded.

Does that remind you of another, bigger non-redaction scandal? 👀
The Weaponization of Non‑Redaction
From the Epstein files to congressional “censorship” reports, MAGA is using "transparency" as a weapon—and calling it accountability.

I don't post on Substack because I already have my own site where I post stuff, and have done for 27 years, and because Substack makes a lot of money off Nazis and fascists and I'd really rather not, thanks. I do have an account there but it's to secure my name. It has a cat photo.

hard to communicate how shattered many basic functions in the City of LA are. we've stopped repaving streets, streetslights are dark, sanitation pickups take weeks. departments bleeding staff bc of budget cuts are also being raided to staff the mayor's pet projects. we can't even spend FREE money
The City of LA is about to give back millions of dollars of previously won money for active transportation projects because it can’t build things in any reasonable amount of time.

When they say "millions" here, they mean over $100M!

Together these awards totaled to:

Wilmington Safe Streets: $32M
Skid Row Connectivity Project: $39M
Boyle Heights Connectivity Project: $32M

(it's notable that the motion omits the embarrassing total)

And yet, every day, our most prominent Democratic politicians, scholars, public intellectuals, universities & university leaders, & other civil society organizations continue to use his platform as their primary social media outlet. One cannot help but notice this & draw conclusions.
The world's richest man is broadcasting eliminationist rhetoric about a tiny, vulnerable minority, and virtually no one is going to treat it as a scandal. It's just normal now.

This society is so sick that we’ve collectively normalized the fact that any one of us can murder someone else (or ourselves) one day while simply driving to the grocery store or work or wherever. Literally end someone’s life. We are a fascist death cult & car supremacy is just another symptom.
The person hit by a driver at Bellevue and Pine earlier tonight has died, according to the Seattle Police Department.

Also, read @karenhao.bsky.social 's terrific book, Empire of AI.

Goertzel is mentioned in the files nearly 800 times, including well after the Miami Herald investigation in 2018.

I still think the best way to think of the ending of US AID is as the single worst genocide committed by any one US presidential administration.

even given all the horrific things the US has done, it's not really that close. 750k dead already; expected 14 million.
this is exactly why I am absolutely not willing to overlook anyone who was once “advocating for ending USAID” as merely committing a little oopsie-daisy-booboo, by the way
The Project 2025 author is using millions of dollars in USAID money for his own security detail.

It is estimated that 762,000 people have *already died* as a result of Elon Musk and Russell Vought’s obscene murder of USAID, including more than 500,000 children.

Vought is a mass murderer.

My favorite culvert story is that Boulder’s creekside paths and ped/bike underpasses are a byproduct of installing larger culverts for extreme high flows. During normal times, there’s enough room for a multi-use path. LA could learn a lesson @lintonjoe.bsky.social

“Stay off the roads” is what she meant to say
Angelenos — The National Weather Service has issued a Severe Thunderstorm Warning for most of the City until at least 12:15PM, and a Flash Flood Warning remains in effect.

I urge all Angelenos – especially those in burn scar areas – to use caution on the roads, plan ahead, and stay informed.
