For NYE, I recommend “Al’s Sparkling Americano”:
- 1 pt Campari
- 2 pts Vermouth
- combine and stir with ice
- fill halfway with tonic water
- top off with a double shot of espresso

Tonight, I’m going with this nice Spanish vermouth, it’s nice and floral. Cheers 🥂

A closing argument for sour cream over apple sauce in the great hannukah debate: dill.
The last latke from our batch, with sour cream and a heaping pile of dill. On kind of a messy plate.

I’d like to introduce an experiment I’ve been working on for the past couple of years: Xarray-SQL. This library asks, what if SQL worked natively with arrays?

github.com/alxmrs/xarra...
Code demoing Xarray-SQL. It reads: ``` import xarray as xr import xarray_sql as xql ds = xr.tutorial.open_dataset('air_temperature') # The same as a dask-sql Context; i.e. an Apache DataFusion Context. ctx = xql.XarrayContext() ctx.from_dataset('air', ds, chunks=dict(time=24)) # the dataset needs to be chunked! result = ctx.sql(''' SELECT "lat", "lon", AVG("air") as air_total FROM "air" GROUP BY "lat", "lon" ''') ```

This is the best figure I’ve seen in a whitepaper in a long time, bravo @ai2.bsky.social, delightful.
Figure 2 Global distribution of data for OlmoEarth pretraining. We randomly sample 285,288 locations based on OpenStreetMap categories. What's your favorite map projection? I like the Peirce quincuncial projection centered on Antarctica. They said it didn't make any sense for this figure though. They said "We hate Antarctica, that's why we don't sample any points there". I said, "Hey, there is one point there!" They didn't have a response to that so they tried to silenced me by deactivating my acc

Puns are not the games of a mediocre mind. Duchamp found in them "a source of stimulation both because of their actual sound and because of unexpected meanings attached to the interrelationships of disparate words [...]. Sometimes four or five different levels of meaning come through. If you introduce a familiar word into an alien atmosphere, you have something comparable to distortion . in painting, something surprising and new."42

This reminds me of Taylor Lorenz’s recent podcast episode on clankers: “Robots won’t be oppressed. Robots will be doing the oppressing.”

On the DOGE for AI website, a slide that reads: Will DOGE 1.0 have impacts in other areas of our civilization? Picture it: In HR disputes, employees who file bully reports can be terminated (teamblind.com). What if we have Al-arbitrators? In insurance claims, what if Al-arbitrators stand between policyholders / adjusters? In IRS tax audits, what if Al-arbitrators stand between taxpayers / examiners? HOH Al arbitrators excel at logic-based and fact-checking disputes to ensure justice ... Can we think bigger? International trade disputes? Environmental disputes? Geopolitical conflicts?

My wife made these stickers custom for us and other speed limit enjoyers of our home town.
A sticker on a blue Subaru that reads “Aromas Pace Car”. Below the words are a row of snails. The sticker is a lighter shade of blue than the car.

This is a funny citation for a machine learning paper.

(arxiv.org/pdf/2103.03206)
But permutation invariance means that the Perceiver's architecture cannot in and of itself exploit spatial relationships in the input data. **Spatial relationships are essential for sensory reasoning (Kant, 1781)** and this limitation is clearly unsatisfying. In the attention literature, position information is typically injected by tagging position encodings onto the input features (Vaswani et al., 2017); we pursue this strategy here as well. While position information is typically used to encode sequence position in the context of language, it can also be used to encode spatial, temporal, and modality identity.

I’m proud to have played a small part in making this pop up on Google Flights a thing
A google flights search results page. Next to the flight, there’s a warning that says: “Contrail warming potential: Medium” Then, when you hover over it, there is a dialog that says: Contrails, or "Condensation trails," are the line-shaped clouds behind planes and contribute about a third of aviations total climate impact. Learn more about contrails.

Gosh, what a chilling news day
Trump, Claiming Weak Jobs Numbers Were 'Rigged, Fires Labor Official Economists said President Trump's decision to oust the head of the Bureau of Labor Statistics could undermine confidence in government economic data. Fed Governor Steps Down Early, Giving Trump Opportunity to Shape Central Bank The resignation comes as President Trump has openly pressured the central bank to lower interest rates and called for Jerome H. Powell, the chair, to step down. Corporation for Public Broadcasting Will Shut Down The company is among the first casualties of a vote to strip roughly $500 million in federal funding from NPR, PBS and local stations across the country.
