@KSeattleWeather The last 2 days we see the pattern of rapidly worsening air quality with a sudden improvement around 12:00. Any idea why? Some industrial activity in south Seattle in the mornings?

@natfriedman PFAS-contaminated biosludge has been used as fertilizer for decades. https://t.co/7GOmIPOc8R

@Empty_America To learn pickpocketing you want to be a child in an area with high foot traffic, density and low supervision. It gives you the opportunity to learn the skill and get caught a few times without serious punishment. Few US children are in such areas

@thebethocracy Seattle's population of kids under 9 years old grew by over 7000 (12%!) from 2022 to 2023 (according to the new Census ACS data released last week). If each student brings $15k/year in funding, an additional 7000 students closes the SPS budget gap. https://t.co/KEaw5olCPE

@Empty_America If you have children, at a minimum, you really want a post-1950s home. Paint manufacturers started restricting lead content in interior paints.

@Empty_America Differences in newer homes:
- Stricter (or any) seismic code
- Fire code (modern wiring, fire rated sheetrock in garage, no balloon framing)
- Restricted hazardous materials (lead in paint /plumbing, asbestos, formaldehyde in wood)
- PEX plumbing resists freezing and bursting

@cremieuxrecueil There was also an apparent peak of several pollutants in the late 1960s-1970s. https://t.co/ylVPBfpucX

I've seen several versions of this lead-crime graph. But, wearing my causal inference curmudgeon hat, I added a few more lines. Many other nasty things took similar paths thx to the environmental movement. My point is the graph. Don't get me wrong lead *is* a huge problem. 1/n

@paulg @michael_nielsen Several strategic bombers were never used in combat at all: B-36, B-47, B-58.

Many families are locked into 3% mortgages and renovating their homes. Beware the risks. I know of 2 families that renovated recently and lead poisoned their young children.

Here’s an example of a Victorian house that poisoned a whole family, pregnant mom, abortion, dogs, nanny.

@pdrmnvd @Master0fNull CTEs can be reevaluated on each reference which gives confusing results if it is nondeterministic. https://t.co/CvY1SI9TQ5

[Kyle Carlson @KyleCSN]

@pdrmnvd @adkravetz Check if any duplicates or nulls crept into the timestamp.

[Kyle Carlson @KyleCSN]

@pdrmnvd I would look carefully at the entire query for nondeterministic operations, for example, the row_number window function. Maybe ask an LLM to help with that.

@DanWhiteCRE @RickPalaciosJr How do we reconcile these results?
