Last week's heat dome had me all worked up to start planting tomatoes and peppers, but the frost last night validated my hesitation.

The actual last frost may have just passed... or did it?

And to be clear that's the order in which I think we should be thinking about LLMs, from most to least important right here and right now.

LLMS are:
- Causing energy demands that commit us to a worse future
- Eroding brainpower of children through adult humans
- Making software and hardware less usable
- Creating a massive economic risk

But sure try to convince me they are worth infusing into every component of our lives.

Hello world, yesterday at dinner my son (15mo) pointed to a swirl on my tie dye shirt and then raised his little arm and made an elephant noise.

I had to tilt my head to see that yes the swirl looks like an elephant trunk. How cool is that?

Why go through the tunnel blindfolded? The whole point is that the rocks there are awesome. Look at the damn rocks! :)

In years past, November has terrible for grandmothers. They seem to drop like flies within a 2-day window of my second Gen Ed exam.

Oddly, it's the grandfathers who are all apparently dead or dying on the occasion of Exam 2 this spring. Maybe ChatGPT is bent against the patriarchy...

Dang, I'm literally firing up my cheap ass rice cooker now. As previously demonstrated, everyone on bluesky is a clone and we're all exactly 39 (and apparently all have instant pots and cheap rice cookers)

Instant pots are nuts. Use saute setting to cook up a big onion and lots of garlic. Add chili powder and oregano, etc. Throw in a ton (6-8 lb) of chicken thighs (frozen even!) + mix well. Add ~2 cups of stock or jar of salsa. Seal & cook for 70 min, then shred the chicken, enjoy, & freeze the rest.

Orthoclase phenocrysts in the granite that makes up the foundation of the Great Wall of China. Lots of chlorite present, too, with the occasional gneiss or amphibolite xenolith.

Or, as is bizarrely common in education, they were told 100 different ways over the last 3 years and still it somehow did not stick. 🤷

Recently returned from a 10-day trip to Beijing, China to visit two institutes of the Chinese Academy of Sciences. Once I'm fully readjusted to the 12-hr time difference, I'll post some observations and takeaways. In short, the people, places, and things were all wonderful.

I found a pack of apple cider donuts in my car. They were about 5 days old. But it's been pretty cold out.

I ate one with a cup of coffee. It was a tad firm but fine.

Now my belly hurts. Being an adult means it's my fault, I guess.

HOME - Project Jupiter Together WHAT IS PROJECT JUPITER? Project Jupiter is a groundbreaking investment to bring an innovative infrastructure campus to Doña Ana County. […]

This here data center, planned for NM, would build a local "microgrid" for power. In reality, it'd use natural gas and emit 2x the CO2 as ABQ + Cruces combined, and it doubles the power production of NM.

Is 14 Mt CO2/yr worth it?

[no]

At least for academics, the right tail of falling productivity is probably due to service commitments after tenure. 🥴

We're all still in agreement that every bluesky user is exactly 39 y/o, right?

The 'individual LLM query scale' is distraction. Think at the systems scale. Climate scientists have been ringing alarm bells to decarbonize our economy for decades, and the tech industry is not only putting on the brakes, but forcing a buildout of gas-powered electricity.

The same question can be applied to many components of our modern systems.

Wasting vast sums of water and energy to run servers for crypto mining, which is mostly to support money laundering... is not worth the climate and environmental impacts.

I cannot take serious any conversation about LLMs that does not immediately weigh [insert benefit] with the massive climate and water use drawbacks.

Every time ask: "Is this worth it?"

I have yet to see cases where the answer is yes.

- Green bean
- Another green bean

After weeks and weeks of trying to hone a method that is new to us, thinking we're maybe the problem... only to discover that the data are great, but it's an utterly new and surprising result that we're looking at. That's a good day.

Should out to the random guy who made a YouTube short explaining how to fix the exact problem with my faucet in like 10 seconds. Didn't even say anything, just showed the fix, and the title was accurate as heck.

Legend.

An added bonus: turning old veggies into stock cuts down on the methane that is produced in landfills when food rots in an anoxic environment.

#Lifehack: Homemade stock. It's delicious, cheap, and smells lovely on a winter day.

Two ziplock bags live in our freezer. We throw in any nearly-bad or off-cut veggies (and bones). Once the bags are full, boil it all up, strain and store in yogurt containers in the freezer.

I do prefer to use wooden stirrers, but the plastic doesn't even soften. I assume it's HDPE but who knows. Try it out, mileage may vary.

Lol, it's in a microwave for about 1 minute and has no water content; it really doesn't heat up. But when I can, I do use wooden stirrers as the tent poles, just to be safe!
