The influence and dominance of conservative media is striking. They have sane-washed and explained away things that would have ended 10 other politicians careers. Trump is Asimovs "mule". His appeal to large groups of people is inexplicable. Vance is certainly NOT that. It's open question how much success the Mule's successor would have. Surely momentum and conservative media will carry him far (should that come to pass).

New comment by marktangotango in "The Daily Scrum: Does It Have to Be Daily?"

marktangotango — Wed, 25 Sep 2024 21:29:31 +0000

At one company (think bank/financial services) I was at as a "software development supervisor" I had to run a daily standup/scrum meeting every day, for 3 years. It really became oppressive over time. That company eventually had layoffs and I left. But they were still doing the daily standup, even when there were only 3 people left.

Indeed there are multiple such optimizations. One that occurs to me is a hub/spoke model where inter-city/state is driverless, from/to truck "yards" on the outskirts of cities. Then human drivers take over and drive the last few miles. Drivers get to go home every night and lead normal lives instead of living on the road.

How is authentication/authorization handled with this stack? Or sign up with email validation and password reset?

Wire length matching would seem to be a big factor in attaining the highest performance.

New comment by marktangotango in "A new quantum algorithm for classical mechanics with an exponential speedup"

marktangotango — Wed, 06 Dec 2023 03:08:59 +0000

Very interesting indeed:

> discovery of a new quantum algorithm that offers an exponential advantage for simulating coupled classical harmonic oscillators.

> To enable the simulation of a large number of coupled harmonic oscillators, we came up with a mapping that encodes the positions and velocities of all masses and springs into the quantum wavefunction of a system of qubits. Since the number of parameters describing the wavefunction of a system of qubits grows exponentially with the number of qubits, we can encode the information of N balls into a quantum mechanical system of only about log(N) qubits.

Cheap SEMs are also useful for electron beam lithography, which has gotten some attention lately with Canons machine <10nm process.

Parsing cobol is actually not bad. The grammar is pretty simple; the "rail road" diagrams correspond to the recursive descent parser very directly.

We did this, and I'd add that repeating what they say back to them so they get that feedback is important too. It's startling to see the difference between our kids and their class mates, who's parents don't talk them (I know this from observing at the countless birthday parties, school events, and sports events). Talking to kids is like watering flower, they bloom into beautiful beings.

> You could consider building this storage system on top of BLAKE3's tree model.

Consider a crypto currency pow that did that without the chunk counter. It'd be trivially exploitably by precalculating all the tree but the chunk that changed per nonce.

Ken Macleod is a Scottish sci-fi author I've enjoyed. Stanisław Lem and Ken Liu are two other well regarded authors; Poland and China respectively.

One of the things that surprised me about social media (facebook in this case) was how people I'd known for a long time could barely string two sentences together, and tended to use meme/gifs in place of what I'd consider "real" communication. I personally would not expect the past to be any different.

Give pointy head bosses (PHBs) insight into who is the most productive. At least that's how my former VP of engineering, the one who measured developer productivety by checking git commit counts, would use it.

Actually, the unreasonably long boom arm is bouncing around significantly, yet the bricks are being place precisely independent of the boom movement. There's some nontrivial PID going on in that brick placement. Plus planning where to place the brick. Optical, lidar? This is impressive imo.

Is there a lego inspired solution to industrial design, specifically mechanical mechanisms? I have had a product in mind that is quite intricate with several possible configurations. I personally haven't excercised my 3d muscles as much over the years and I find cad with 3d printing to be not as intuitive as snapping parts together.

We should not be surprised how much ignorance there is around this. Networking even for technical people can be a "black art".
