JPL has been run by CalTech for 90 years because it's the CalTech rocketry club founded in 1936. Its services are some of the most productive investments of the US federal government.

You're looking at this as basic MIC M&A. If they wanted to cut the budget or be more efficient they could just rewrite the contract as they always do at renewal. This is a theft of expertise.

124.4 meters (408.1 feet) tall, 9 meters wide, 5,500 metric tons at launch with a TWR of 1.6. Should leap off the pad and hit max Q in 45 seconds. These engines are grossly overpowered for the launch mass, which implies another stretch. And they're a work of art.

I have to go see one of these launches one day.

And they're not done. Raptor 4 is in the works. They really are going to Mars. The long dry spell of "boldly go" is coming to an end.

Grading on a curve was meant to hide the fact that some teachers couldn't teach, some could, some wouldn't, and others would. It protected the professor at the expense of the students' education.

And it ruins grades as a marker of achievement or ability. From a student's perspective, if I pay for a course, the result should be that my grade reflects the degree to which I've mastered the material, not the variations between the quality of the students and the quality of the instruction. Grading on a curve allows a deadbeat professor and a deadbeat class to essentially turn the class into a credential mill without the necessity of education.

Students can safely assume that courses graded on a curve are staffed by incompetent or lazy professors, taken by lazy or incompetent students, or quite possibly both. When I was in university, this type of grading was used most often in the general education electives, where the professors didn't really care about the students, and the students didn't care about the subject. To adopt the same approach for mainline courses is to transform the entire university from a place of learning into a credentials broker or diploma mill.

Comment Re: Well "just" vibe code you a new API, then eh? (Score 3, Informative) 46

The biggest problem with replicating CUDA is not the technical aspects, but finding VC with enough brains to know whom to hire. Most CS grads have the knowledge, but not the drive. Most liberal arts grads have the drive, the creativity, but not the knowledge. You need to find one with both, because creating the next Nvidia killer will require someone who is boring enough to reinvent the wheel, but has enough creativity to find novel solutions to performance problems.

The computer science and hardware engineering behind the hardware and software (Nvidia/CUDA) have been known for decades. The Nvidia hardware could be replicated with FPGAs - notwithstanding any patents Nvidia might have. The software API could be replicated rather easily; parallelism has been known and studied in computer engineering (again) for decades now. What Nvidia did was political - they provided both the hardware and the API to easily use it in one package which could be understood by the C-Suite class. The challenge was never technical, but marketing.

More specifically, you'd need to understand how compilers work, and how to use YACC or bison, or something similar to generate the compiler code for you. You'd have to understand digital logic and how to create logic functions with NAND gates. If you see an FPGA development kit, know what it is, and think to yourself, "What I could do with that..." you're probably a good fit for the job. And you'd need someone willing to bankroll your project until you could demonstrate that you beat Nvidia on something marketable - like floating point performance. Or power consumption.

From an engineering standpoint, what Nvidia has done is trivial - because the solution could be reproduced by an engineer using already known techniques. But what Nvidia did was to combine technical knowledge with an understanding of their market to produce the dominant position they have today. Any computer engineer worth his diploma could produce a design with FPGAs that would beat Nvidia GPUs, but Nvidia did it first.

This is a non-issue in reality, and reads like FUD, at least based on my experience with EV charging. I wonder if the usage in your area is extra weird (or maybe in mine?). I've never had to wait to DCFC (I've never even had to use an NACS plug, even though I have adapters). I'm confused as to what you're seeing?

Comment ebikes are dangerous! (Score 1) 244

Speaking as a motorcycle rider, ebikes are dangerous. Not because of the bike but because of the riders. They often don't wear safety gear, they don't follow traffic laws, and many bikes top out at 70-80kph. It took considerable effort to get my Class M. A bike going that fast should require licensing and safety courses and helmet laws. Most people don't realize they can squid out on the road on an ebike just like you will on a motorcycle without proper gear.

I just installed Fedora 44 on my old Win10 laptop. Because Microsoft made sure this perfectly good laptop with 16gb RAM could not run Win11. And Affinity Suite runs great on wine now. And no obnoxious telemetry tracking. Oh yeah, for games: steam and lutris too.

Submission + - Maryland Becomes First State To Pass Bill Banning 'Surveillance Pricing' (denver7.com)

An anonymous reader writes: Maryland is poised to become the first state in the country to ban "surveillance pricing." The practice refers to companies using a shopper’s personal data, such as browsing history, location, or purchasing behavior, to tailor prices to individual customers. The Protection From Predatory Pricing Act, passed this month and sent to the governor for a signature, would prohibit food retailers and third-party delivery services from using the practice. Violations would be treated as deceptive trade practices under state law, with potential fines and lawsuits.
