Comic. A snake slithers around a hypercube. No two non-consecutive parts of its coils can be on adjacent corners. [Three small 4-dimensional hypercubes showing disallowed options with one large cube with snake wrapped around it. Dimensions = 4. Max Length - 7.] Snake(N) = Longest snake that can fit in an n-dimensional hypercube. Snake(N=1, 2, 3…8) = 1, 2, 4, 7, 13, 26, 50, 98. Snake(N>8) = UNSOLVED. [caption] It turns out every scientific field has a key thought experiment that involves putting a cute animal in a weird box for no reason. So far, quantum mechanics and graph theory have found theirs, but most other fields are still working on it.

Skateboarding Into Middle Age As I approach forty, I have fewer and fewer memories of being a child. It is enough that the body remembers.

β€œI’m not the same person I was as a child,” Navied Mahdavian writes. β€œBut some things remain.” Read his comic on re-learning how to skateboard.

White House unveils AI action plan targeting regulation and β€˜ideological bias’ The Trump administration’s goal is to make the U.S. a pro-AI innovation economy, relying on less bureaucratic barriers and open-source models to help win the global tech race.

President Trump’s AI action plan β€œseeks to require that 'the government only contracts with' developers who meet the administration's ideological criteria," EFF’s Kit Walsh told Nextgov/FCW.

Panel 1: A swordsman with a short, ragged red cape, 2 brown belts, and a shoulderpad, stands with a wide stance and his sword drawn in his right hand. We see him from behind the shoulder of his opponent, who seems to be wearing blue. Something is written on the red swordsman's chest, illegible from this distance.

Panel 2: We zoom in. What's written on the red swordsman's chest is "GOOD". He says "We could have been friends, you know."

Panel 3: The perspective is turned as his opponent is revealed to be wearing a long blue cloak and rectangular framed glasses. The wind billows his cloak.

Panel 4: The blue swordsman shifts his cloak to draw his sword, which glints in the sunlight with a "shiiiiing". It is revealed that on his chest is written "PERFECT". He responds: "No. We couldn't have."

NASA is more than rockets and moonwalks. NASA is behind much of our everyday technology. From space discovery, to Air Jordans, to CAT scans, NASA has played a role. We get it all on less than a penny of every federal dollar. Now their science may be gutted by 50%.

A thing that deeply troubles me about my field is that people tell me that programming doesn’t give them a sense of purpose, challenge and fulfillment.

No, the great big beautiful tomorrow is them yelling at a simulated human slave until a barely working piece of software materializes.

A truly historic day in California: a clean CEQA exemption for environmentally friendly infill housing has just passed the California legislature via the budget bill!

No other way to put it: this is the most transformative positive shift in land use policy in this state of the last 50 years!

All the criticisms I've read so far are not in defense of Schumer but rather pointing out that the quote you screenshotted doesn't support the claim you made.

If there isn't evidence to support your claim than it is either a gross misinterpretion or intentional mischaracterization.
