There is bioweapon potential in these combination of technologies beyond simply engineering a virus, I won't go into detail here, since maybe (however unlikely) no-one else has come up with this particular scheme. However recent work b

It is ok to feel lost and overwhelmed from time to time. Even the most brilliant people often go through hardships and difficult times. Try to find things to do that you enjoy not because other people expect them of you. External validation

One of my first memorable PhD experiences was getting invited to an impromptu meeting in Lithuania, where we met a Finish and Lithuanian scientist both working on astrocyte models and wondering how that could be applicable to neuromorphic h

In academia there always is a difference between the way results are advertised and what conclusions are drawn internally. This is more true in some fields than others, I'm most familiar with it ML, Physics. Part of your skill as a res

I think there is an expert vacuum that was filled by opportunists and enabled politicians to decide non-sensical measures. Compare that to the situation in Taiwan, where the vice-prime Minister is an epidemiologist.

It tells you a lot of the level of expertise in a country, if a physicist like Viola Priesemann previously not involved in any kind of disease modelling is able to be a significant voice in the national conversation. The 'experts'

As a working physicist I would agree with you for the most part. Science fiction doesn't help because it doesn't contain ideas, which work beyond a surface plausibility level. However you can still get inspired by them in indirect

It seems obvious that USAID is an intelligence front (I've encountered a few instances where it was mentioned that someone worked for USAID at the time, while it was simultaneously obvious that it would make way more sense if they were

At least in Germany (where I am from), but I believe also other places in Europe, it is pretty common to do a PhD that is partially or fully funded by some company. For example Apple, Bosch was looking for ML PhD students at my university.

Realistically I think really high profile research labs will want you to have some published work or for whatever reason know that you are a really talented programmer and will hire you as a scientific programmer. I know at least one pers

From the country that brought us Mozart, World War 1, Wittgenstein, Gödel, Hitler. So this is either a brilliant or horrible idea ^^

Yeah it also lead to trillions in wealth increase of the ultra rich. There also is a difference between deliberately investing in vaccine companies and then publicly advocation for patent protections to remain in place and buying a vanguard

The (western) COVID vaccine manufacturers still make ~1000$/s in profit from them. Gates / BMGF are invested in literally almost all of them, even the obscure Indian ones, not just Moderna and BionTech

Lean4 comes pretty close to a general purpose dependently typed programming language.

most of that processing power is unfortunately special purpose and can't be easily repurposed for something else. We have very good vision processing, but it is not like you can entirely high-jack that for something else.

There is always a shortage of talent at the right price.

During my PhD I burned through ~10^5 of compute hours on 4-8 V100 GPU, 128 Core, 1TB+ HPC nodes. Your 10k AWS credits run out really quickly compared to that. And as a startup you are far better of spending some money on a few beefy machine

I would say I'm relatively pragmatic. My main use case would involve DifferentialEquations.jl modelling either certain quantum processes or model equations of biological neurons. I have a rough idea how that would work and what kind of

Ha, yeah I knew that analysis of how to do second order adjoints fast :), in what is basically documentation no less. I figured someone would probably do a ML paper on that eventually. I have had a hard time judging, what is non-trivial in

The pytorch lightning people have come up with grid.ai, I personally have obtained good results by using pytorch lightning plus slurm on HPC machines. If I were a startup, I would probably try to build my own small HPC cluster, since that i

I agree that it is a good name and evaluating this on "ML tasks" was novel. However this and subsequent papers did a really poor job in delineating what is novel, from what is well known. Moreover this is a pattern in almost all

Neural ODEs are essentially a rebranding of adjoint sensitivity analysis, which has been around in various forms in established solver suites, such as Sundials, PETSC, etc. The machine learning community got a hold of it, cited one book and

I think it would have helped if the people writing that paper had not confused the issue by introducing a new name for something that is a well known thing in optimal control and had been invented even before neural networks, namely adjoint

I have a PhD in physics and studied graduate level mathematics. Naive set theory is sufficient for basically everything except a few instances, where you have to bite the bullet and invoke the axiom of choice. But this happens rarely and ty

GCC and ICC typically do a reasonable job, with the right flags: https://godbolt.org/z/6a8no4n5a .

I think shader specialisation is handled pretty well in circle. Since you can essentially run arbitrary C++ code at compile time, selection and specialisation of a shader can even depend on hardware specific benchmarks. There is an extensiv

The circle compiler has this feature and many more, like CUDA, Vulkan support.

You can do that with ROOT aswell.

I had this thought that it might be possible to define some of the social media interfaces in terms of CapnProto services. Then it wouldn’t matter where the service was hosted. Especially for things like LinkedIn the major draw is that CV d
