We used neon at last job. It seemed pretty cool. What made you switch to planetscale?

If it wasn't confusing what made you bring up the space program and fixing roads?

I was offering a tangible example of where the thing being proposed was a failure.

Updated - since my text was confusing. The subject at hand is subsidized grocery stores, the USSR is an example of failed centrally planned subsidized grocery stores.

Yeah it was so successful that people would line up around the block for bananas the one time a year. Or when boots came into the store you'd pick up whatever size you could, as you'd trade later.

Just because we can does not mean we should.

Here's how this will pan out.

- A number of "officials" (friends) will get cushy jobs for running this program.

- It will lose millions of tax dollars

- a small portion of the population will get cheaper produce for a photo op

- Mamdani and friends will call it a success

- But net, this will be net negative for the city (ie. tax dollars to crony jobs and subsidizing food for some).

Whats the point? The USSR has tried this (subsidized grocery stores centrally planned). Lets not.

If on the other hand, the issue was hey its expensive to bring produce XYZ, so why don't we work to reduce that cost by legalizing Kei [1] trucks and exempt from tolls. Now that would be something interesting.

Do you think threats and missiles from an adversary are insufficient cause for war?

Right someone saying they want to kill you and building an arsenal is not sufficient, the missiles have to be flying towards you, you have to let them pull the trigger before you can respond.

This is the flag of the Houthis [1], they are sponsored by Iran, as are the likes of Hezbollah, and Hamas. They have similar language in their charters.

How is that not casus belli?

The business owes the money or the fund. In any case the individuals do not unless they backed it with personal collateral.

That’s a good signal for you. When you find the person who did look you will know they stand out.

This article is sparse on details.

How much energy, how long is the pulse, how close were the drones?

Regardless I think the primary challenge with these systems will be energy on site and a surge of it during waves of attacks. Charged up capacitors can only handle so many waves.

Personally, the Boeing 737 air max was the worst. Multiple crashes. Corporate incompetence, coverup, and denial.

You don’t need to spend anything more than kettle one. It’s a super simple lab process it’s not like whiskey which has a lot of complexity.

In helium there was no input revenue. OP mentions payment to send. This is a very different scheme.

Awesome! Let me know how your experience is or if you have any questions.

I went pretty simple, used OpenAI agent sdk and built a couple of tools like “run_query” with read only connection. Initially I also had a tool for getting the join path from A to B, but the context I wrote out was sufficient.

I think main challenge with this agent is how to keep the context up to date.

Doesn't this create a signal problem long term?

If everyone is using it now prompts aren’t a good gauge.

I built a SQL agent with detailed database context and a set of tools. It’s been a huge lift for me and the team in generating rather complex queries that would take non trivial time to construct, even if using cursor or ChatGPT.

Driving is not error prone, cars rarely break in unexpected ways.

People driving and making decisions are error prone.

A simple test is to watch how people turn. Do they turn early potentially hitting the curb or cutting it too close to pedestrians. Or do they increase their radius by turning late? The latter are better drivers.

Edit: here are more tests,

- do they signal

- do they cutoff others

- do they let those who signal in

- do they drive too slow or too fast for the given road and conditions

- do they have an awareness of all cars around them

- do they block the passing lane

- do they maintain a reasonable distance behind other cars

- do they let emergency vehicles pass

etc.

How do you do metrics across users? Do you have long running or many jobs across tenants to get derived data into one downstream target?
