This isn't even his personal blog. It's the company blog of Hey that he's using to push his views. Do you really wanna work with a company whose professional blog references "[insert ethnicity] rape gangs" and "the decline of Europe". He could go full Kanye at any point.

culi··on S.F. Democratic Party stands behind Flock surveillance cameras in vote
> Both sides acknowledged that the city’s Flock camera data was illegally accessed more than 1.6 million times in 2024 and 2025, with lots of those searches reaching out-of-state agencies like Immigration and Customs Enforcement. And, more recently the San Francisco Police Department admitted around 300 out-of-state illegal searches had happened in the last year.

If the abolition movement wants progress we should start throwing white collar criminals that allow this to happen in prison. See how quickly those with power will start considering transformative/restorative justice alternatives

We already have laws making a lot of what Flock does illegal. We just don't enforce them

> Last month, the San Francisco Standard reported that a prior version of Mar’s resolution was removed from the party’s agenda by a subcommittee chaired by Ho.

> The committee does not have rules related to conflicts of interest for issues like this one, Tung told Mar. They then proceeded to count both Ho and Chandler’s votes.

culi··on Pentagon says overreliance on AI contributed to missile strike on Iran school
Also Iran, by comparison, has zero schools on military bases. That Minab elementary school plot stopped being a military base in 2013. It was 3 years later that they decided to build a school there instead. Even Google Maps marked it as a school and it was painted bright pastels with obvious signage.

I don't know if you're doing it on purpose but Minjur is one of the most controversial sites in the desalination debate because of how much its bankrupting the government to fund it for such little water back. It's funded because of political necessity in SPITE of economic viability.

We just literally don't have the technology yet. It takes an immense amount of electricity/energy to desalinate ocean water which is way more saline than brackish water. The other half of the cost is in the very high rate of corrosion of equipment.

I'm not against desalination of oceanwater. I absolutely support funding more research into it. I'm just explaining the current state of technology. It just doesn't currently exist.

culi··on Transit rewards
The Transit app is great for this kind of stuff and many cities have integrated their transit options under a single payment system so you could actually do this. It can even take into account if you have a bike or not and you can specify stuff like "avoid busses".
culi··on Transit rewards
Things are changing though. LA (arguably the car city) has been heavily investing in public transit options. We have decades of scars from the automobile industry being able to drive transit policy to make up for but I think that age is finally waning. Ofc we're still far behind Europe and China where NYC seems like the bare minimum of public transit

If you think that's bad, you should look at the financial returns on highways and roads! A much grimmer picture

You're more likely to convince someone by pointing out the valid parts of their concerns than to outright dismiss them as rightwingers.

Palantir's Maven is not an LLM. It embedded Claude as its model. Claude was the one suggesting targets (humans were the ones approving them)
culi··on Pentagon says overreliance on AI contributed to missile strike on Iran school
The US has more public schools on military bases than any other country. Over 160. And that's not counting the private schools
culi··on What California is learning from solar panels built over irrigation canals
yes they are draining the dead sea. It's an environmental disaster and the loss of one of the most unique environments on earth.

I made a very clear distinction there between brackish water and ocean water.

The solar cells are tightly glued to the glass. Glass is easily recyclable but obtaining it and cleaning it is nearly impossible. It's also treated with antimony to increase its durability which limits how you can handle it. About 90% of all glass in solar panels has been landfilled.

A minor point anyways. Glass is not exactly a precious resource.

The most valuable parts are obviously the silver (about 50% of a panel's scrap value despite being 0.1% by weight), aluminum (about 20% of value), silicon (about 15%), and copper wiring (about 10%).

We are only just beginning to figure out techniques to reclaim the silver using thermal heating and chemical leaching techniques

It's definitely brought up by anti-solar crowds. It's more accurate to point out that the risk is small rather than to dismiss the genuine concern. Solar panels can actually increase water quality because they replace diesel generators according to this nature article

https://www.nature.com/articles/s41893-021-00693-8

The concern is not completely unwarranted:

> Because over-canal systems are subject to a more humid environment than ground-mounted systems, over-canal PV panels might have increased reliability problems45. In tropical conditions, the water content in the encapsulant can exceed solubility, which can lead to the formation of droplets of water in the modules, sometimes causing corrosion or other problems

But overall "field experiments have shown that CdTe semiconductors can withstand hot and humid environments."

culi··on What California is learning from solar panels built over irrigation canals
A small risk according to this nature study. Especially in tropical environments where humidity is already high.

https://www.nature.com/articles/s41893-021-00693-8

https://sci-hub.ru/10.1038/s41893-021-00693-8

But more importantly it found that these solar panels are replacing diesel generators that pose a much larger pollution risk so water quality actually improved.

culi··on What California is learning from solar panels built over irrigation canals
It's bad but one thing not often pointed out in this conversation is that about 50% of water used in irrigation for agriculture returns as groundwater. In most other cases, used water ends up in sewers or evaporating
culi··on What California is learning from solar panels built over irrigation canals
Most desalination plants (at least the ones that are economically viable) focus on brackish groundwater, not ocean water. This contributes to the problem GP is pointing out. California already does more desalination than any US state other than Florida.

But there's a million environmental restoration projects we could be doing right now to increase the water holding capacities of our environments that are simply not being sufficiently funded. The science is pretty well done on most of these strategies while desalination of ocean water is still mostly an experimental technology that is not economically viable.

culi··on What California is learning from solar panels built over irrigation canals
I think they're trying to point out how little effort is put into environmental restoration that would allow our environment to hold more water instead of having most of our rainwater wash out into sewers. Some of the loss in the environment's ability to hold water is due to large infrastructure projects in the first place. We are heavily draining the landscape and its causing us to lose critical topsoils (some of which took thousands of years to make).

Compared to 200 years ago, water moves around much more but California overall has MUCH less water.

grid maintenance is massive but wildfire liability is a larger problem California faces more than any other state

if only California didn't ban cultural burns in the first place

culi··on What California is learning from solar panels built over irrigation canals
Amazing what California can achieve when they don't have to deal with constant cease-and-desist lawsuits, eminent domain battles, environmental review challenges, etc (crying in high speed rail)
culi··on What California is learning from solar panels built over irrigation canals
they're hitting those too to be fair. In South America its a big problem in communities that are really poor. The components of even CCTV cameras are so valuable that surveillance cameras get taken down almost immediately

culi··on Iran school bombing: grounds to believe US was behind atrocity, UN finds
I said UN report and the Pentagon report. The NYTimes leaked an early Pentagon report but I didn't save the original article. All I have is this quote I saved from it, but when I google it the original article doesn't show up:

> At least 165 people, mostly schoolgirls, were killed. One official cited by The New York Times said, “We are still looking into the strike, but the evidence increasingly points to US aircraft as the source of the school being hit.” US authorities have acknowledged the inquiry but have not officially claimed responsibility.

Any ways I think it's a little obfuscated because the initial wave of airstrikes started at 11:22am and there were 9 in total, several hitting near the school and at least 2 hitting the school directly. All of this happened in less than 2 minutes according to a joint investigation by Sky News and Forensic Architecture.[0] I think that's also the source of the confusion of whether this was a "triple tap" or "double tap"

culi··on Iran school bombing: grounds to believe US was behind atrocity, UN finds
Reuters title is literally: "The primary school targeted in the attacks bombed twice, 40 minutes apart in Iran"

https://www.reutersconnect.com/item/the-primary-school-targe...

EDIT: and here's Forensic Architecture https://forensic-architecture.org/investigation/airstrikes-o...

> Mohammad Yazdanpanah, a driver with the local fire department, said: ‘About half an hour, maybe forty minutes after we had arrived at the scene, there were two additional explosions, one after another. At that time there were perhaps one thousand to fifteen hundred people gathered in the compound and around the area. When the first explosion happened, we immediately threw ourselves to the ground to seek shelter. Just a few seconds later—perhaps three or four seconds afterward—a second explosion followed.’

culi··on Iran school bombing: grounds to believe US was behind atrocity, UN finds
I don't think a third strike is confirmed, but I also think "double-tap" is more of a category meaning "followup strikes to hit responders" so I wouldn't be surprised if 2 followup strikes instead of 1 are still categorized as a "double-tap strike". It seems like splitting hairs either way. We know that the strike caused surviving teachers/students to congregate in a prayer hall. 40 minutes later that was hit as well killing almost everyone

The thing I most struggle with in this domain is recalling information from videos. I watch/listen to a lot of hour+ lectures and I rely on this website deeply:

https://filmot.com/

It lets you search YouTube transcripts. If you could somehow integrate video transcripts into this tool, I would be extremely interested in trying it out

culi··on Iran school bombing: grounds to believe US was behind atrocity, UN finds
40 minutes almost exactly. The teachers and surviving students rushed to a prayer hall for protection and then US aircraft (not surface to surface missiles) hit the building a second time killing almost every student and teacher as well as first responders

These are all detailed in both the UN fact finding mission and the US' own investigation.
