Since El Nino was officially declared today, here's a ZERO hype reminder of how little it impacts Sierra Nevada snow pack in California over the last 23 years. In fact, La Nina clearly has a greater impact.

More evidence against El Nino hype.
Looking at the last 22 years, there's no evidence strong/moderate El Nino contributes to wetter weather. Only 2 of the top 10 years were moderate. 6 were Nina's!!!
The opposite seems to be true in a changing climate.

Our trail fires page is ready for the upcoming fire season. We've added video that shows smoke, hotspots, burn scars and fire weather index over the last 72 hours, in 1 hour increments. Choose your trail.

El Nino: Hazard or hype?
Social media is awash with "weather wandas" seeking clicks, professing doom & gloom about El Nino. Here's a look over the years of its impact in California, in terms of precipitation.

967 distinct eco-regions from the @EPA for CONUS, levels 1-4. That's 5,842 at level 4. Base map turned off for clarity. Zoom in to increase eco-region level. Click for name:

It seems folks are struggling with @fema Flood Hazard (NFHL) data.
Here's a notebook on creating your own spatial database, allowing you to query by FIRMID, FIPS, date, geometry and retrieve data in bulk:

At best, AI will bloat your code base. At worst:
Mar 10
Amazon is holding a mandatory meeting about AI breaking its systems. The official framing is "part of normal business." The briefing note describes a trend of incidents with "high blast radius" caused by "Gen-AI assisted changes" for which "best practices and safeguards are not yet fully established." Translation to human language: we gave AI to engineers and things keep breaking?
The response for now? Junior and mid-level engineers can no longer push AI-assisted code without a senior signing off. AWS spent 13 hours recovering after its own AI coding tool, asked to make some changes, decided instead to delete and recreate the environment (the software equivalent of fixing a leaky tap by knocking down the wall). Amazon called that an "extremely limited event" (the affected tool served customers in mainland China).

China has now built 1.2 TW of solar capacity as of the end of 2025.
Assuming just a 21% solar capacity factor, that much solar could power every single home in America.
This graph is even more insane than you think it is.

Kubernetes killed more startups than server crashes ever did
You don't have Spotify's scale. You have 8 engineers and a single server that's running fine
But you watched a KubeCon talk, and now you've got 23 YAML files, a Helm chart nobody fully understands, and engineers debugging pod evictions instead of buildinga product
Your "cloud-native infrastructure" is just a cloud bill with extra complexity
A $50/month VM can handle millions of requests. Your startup will run out of money debugging networking issues long before you need horizontal pod autoscaling
The best infrastructure decision is often the simplest one

Southern California #PacificCrestTrail has seen 400% of normal #precipitation for the first 3 months of the water year. That's 30 inches vs 5 inches of #rain in some areas.

Anyone notice a massive increase of bad internet traffic coming from South America over the last few months?
