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 check for these kinds of things. Some of them ju

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 deaths per 10 billion passenger-miles flying. Converting into

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 used to be that the only way to get access to thousand

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 some sense all animals (including humans) wandering on

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 conversations nearby). It can go two days between char

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 pattern between light moving along each of the dimension

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.

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 300K-400K miles. My brother's Corolla was rear-ended by

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 supercomputers and in the cloud.

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 Legion/Regent. [1]: http://theory.stanford.ed

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 you've asked for it), it's optimized, and then dis

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, Terra, and Lua. Writing Regent code is much higher produc

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. Anyone who has ever use libraries backed by MPI in any lan

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've been working 60-80 hour weeks for the past 10 years.

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 specific details but are not so good at picking up motio

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 executing in parallel. History (so far in most cases) has shown th

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 to dig their heels in and assert that it is good enoug

NVLink works fine between GPUs even if the CPUs are x86. Just look at the NVIDIA DGX boxes/stations. https://devblogs.nvidia.com/wp-content/uploads/2017/04/NVLin...

I have a CS PhD from Stanford (graduated 2014) and it is definitely worth it. The thing it actually buys you is freedom to choose your own research, which you can't do with a bachelors or a masters. I now work at an industrial research

All programs are proofs and their results are theorems[1]. If "math is naturally inherent and merely discovered by humans" then so are all programs; programmers are just discoverers and not inventors. Given the proof of Curry-Howa
