The Trinity test took place in New Mexico, not Nevada.

It feels like there should be some kind of tool analogous to valgrind/ASAN/TSAN/UBSAN for code that is just run on all the images of any kind of paper before it is published to che…

We can compare against another mode of human-controlled transportation. There are 1.37 deaths per 100 million passenger-miles driving in the US [1]. In comparison, there are ~0.2 d…

To be fair, it's never been easier to get access to thousands of GPUs in the cloud. It might be expensive, but that is an entirely different kind of barrier. Just a decade ago, it …

Alright, here's an idea: consciousness is spectrum that occurs when a system develops an automatic self-correcting mechanism for interacting with the external physical universe. In…

Ironically, in the US, most of the people that want to secede are the ones in states receiving more taxes than they pay.

I'm still using a Pixel 2, now 4.5 years after I got it (lack of security is easy: don't put or do anything I care about on the phone, turn off the power when having sensitive conv…

The clever thing about interferometers is that they're actually measuring space and time in two different dimensions concurrently and then looking for changes in the interference p…

I never said it stopped all transmission, but it will stop a large fraction of it. We're playing games of probability. Anybody that deals in absolutes is living in a fantasy world.…

> What again is the rush to vaccinate the lowest risk age group? Because they still contribute to chain of transmission to the most vulnerable members of society, likely in a dispr…

In my experience, the whole 10 year warranty seems a bit excessive for vehicles that are nigh close to indestructible [1,2,3]. My parents have had multiple Toyotas that made it to …

Please correct me if I'm wrong, but I think all of those system only work inside of a single process. Legion/Regent support distributed multi-node multi-process execution both on s…

Prior to working on Legion, I worked on a programming language called Sequoia that matches much of what you are describing [1]. In many ways Sequoia was the spiritual ancestor of L…

The main difference between Legion and TensorFlow is how and when the dataflow graph is constructed. In TensorFlow the graph is constructed lazily (no execution is performed until …

It's worth noting that Regent is the language that implements the Legion programming model. The Legion runtime system is just a C++ library with bindings for C, Fortran, Python, Te…

SF to Amsterdam is 5448 miles, which is 0.29 lightseconds, or 29ms at the speed of light, or about 2 frames of 60fps video, so 5X faster. :)

Except they have no story for building composable libraries in a distributed setting. The story for distributed execution in Julia today is just use MPI, which is a terrible answer…

python: sum([n * n for n in range(1,5,3)])

I had the same thought. The meta-customers here are the insurance companies. If you can prove that the tool improves the performance of doctors so that they get sued less when they…

As someone who has been very laser focused in life I often feel the opposite of you. I finished university, did my PhD, and now have a job doing research in the area of my PhD. I'v…

Actually there is some vision science behind this phenomenon. Your fovea is what you use to focus on things and it's got lots of cone cells that are good at picking up colors and s…

> Smokers and cigarette manufacturers seem to not have some negative third party by your definition Sure they do. If rates of lung cancer go up because more people smoke, insurance…

Probably not. The out-of-order execution units in the cores rely heavily on register renaming to remove anti-dependences in the instructions stream and get more instructions execut…

It's true that it could happen with any language, but it seems to be especially prevalent and widespread with Fortran. Something about the culture of the language encourages people…
