There's actually a lot we don't talk about related to cars and the military industrial complex. My point that internal combustion engines align the citizens and the military (by forcing citizens to rely on the critical resource at the center or the military industrial complex) remains evergreen. But people also generally don't realize that the manufacturing infrastructure of cars is fungible, and can be shifted to aircraft and tanks when needed.
Car manufacturing capabilities are intimately related to militarism in a way that bicycles aren't. That's also worth thinking about.

"This single task of managing memory has proven to be one of the most difficult, let alone to grasp and understand, but most importantly, to get right.
Because not getting this right meant crashes, security issues, resource shortages, unhappy customers, and lots of white hair. To make things worse, pretty much every programming language comes these days with their own ideas of how to keep track of things on the heap."

Exploring vibronic dynamics near a sloped conical intersection with trapped Rydberg ions

Abstract: We study spin-phonon coupled dynamics in the vicinity of a sloped conical intersection created by laser coupling the electronic (spin) and vibrational degrees of freedom of a pair of trapped Rydberg ions. We show that the shape of the potential energy surfaces can be engineered and controlled by exploiting the sideband transitions of the crystal vibration and dipole-dipole interactions between Rydberg ions in the Lamb-Dicke regime. Using the sideband transition, we realize a sloped conical intersection whose cone axis is only tilted along one spatial axis. When the phonon wavepacket is located in the potential minimum of the lower potential surface, the spin and phonon dynamics are largely frozen owing to the geometric phase effect. When starting from the upper potential surface, the electronic and phonon states tunnel to the lower potential surface, leading to a partial revival of the initial state. In contrast, the dynamics drastically change when the initial wavepackets are away from the conical intersection. The initial state is revived, and is almost entirely irrelevant to whether it is from the lower or upper potential surface. Complete Rabi oscillations of the adiabatic states are found when the wavepacket is initialized on the upper potential surface. The dynamics occur on the microsecond and nanometer scales, implying that Rydberg ions provide a platform for simulating nonadiabatic processes in the vicinity of a sloped conical intersection.

Just fixed an interesting and subtle shader performance bug.
Here I'm trying to recover a clock from a PAM-3 signal which consists of two consecutive filter blocks: the PAM edge detector (find level crossings and interpolate, accounting for the fact that the threshold changes depending on start/end symbol), and then the CDR PLL proper.
If you're not familiar with NSight Systems especially on complex multithreaded applications, there's a lot going on here even though I…

Republican senator has introduced a bill to ban Americans from holding dual citizenship,
in the latest attempt by the right to attack immigrants and tighten the rules around what is permissible with regards to American citizenship.
Sen. Bernie Moreno, a Republican from Ohio,
introduced the legislation, entitled the “Exclusive Citizenship Act,” on Tuesday.
The bill makes the sweeping assertion that people with foreign citizenships may have “conflicts of interest and div…

Good Morning #Canada
B.C. is full of hipsters, Alberta is oil obsessed, Ontario has a superiority complex, PEI prays to potatoes, and all Newfies drink Screech at breakfast. Every Province and Territory is known for their unique habits, culture, and views of the world. And we all hold expectations and misconceptions of our neighbours across internal borders. Hey, it's a long winter and we need some gossip to get us to the end of it.
The attached video provides a detailed rundown of stereotypes for each Province and Territory, and some of the content is accurate, like Toronto being the centre of the universe. It's a bit long but you can select a chapter to check out your Province, or one that you dislike. My favourite is Albertans pouring oil on their cereal.

MERCENARIES is a video and poster campaign to counter ICE recruitment.
The distribution model for this campaign is both decentralized and autonomous.
They ask, "Please help us circulate these everywhere that people are at risk."
