I'm just relaying what most guitarists that have played with him have said. Watch a few interviews, jazz, flamenco, whatever he plays.

Here an example of his playing: https://www.youtube.com/watch?v=C97H_HvBjPA

30 years playing guitar, I believe I can recognize masters, but this guy is just wow.

Just a minor note. Howe is good, one of the best yes, but Paco De Lucia reigns far above them all.

I have a few from schitt that have been pretty solid for years, I highly recommend them.

Yes, it just means you have to solder the switches yourself. From their website:

This is a special version of Glove80 meant for users intending to replace key switches. Soldering is required for this keyboard to function.

This looked so good until I saw it requires switches to be soldered (by them or you). Hot-swappable switches is a must for me, specially at this price point. I guess my ergodox will have to last a bit longer until a proper replacement is found.

Thanks for the suggestion. Good luck with your project.

I tried to use it but I had some issues as others in the thread.

I have tried many sources and method over the years and settled on spleeter [0]. Works well even for 10+ minute songs, varying styles from flamenco to heavy metal.

This is the only combination I also went with, nothing else seemed acceptable on the android side. GrapheneOS has been fantastic, no Google apps.

Yes. The librem 5 is a somewhat solid alternative. The pinephone seems to remain a developer platform as it lacks simple features expected out of a phone.

It is not a single language. c, C++, Fortran are the most commonly used. The communication happens using one of many versions of the message passing interface [0] (MPI). MPI essentially spawns child processes and a communication ring between nodes using whichever interconnect is available (usually infoniband).

Large-scale simulations of phisical systems tend to have a variety of length/time scales that require vast numbers of CPUs to model in a timely fashion. This could be anywhere from a few hundred cpus to tens of thousands. Fluid dynamics, solid mechanics, fluid-structure interactions, electrohydrodynamics, etc. simulation tools can all benefit from having a larger number of highly interconnected CPUs, we can simply resolve engineering problems better with more computational resources for better understanding of problems.

Reasons : there is a significant amount of work needed to get codes to work on a distributed hybrid or gpu-only fashion. It's a completely different coding paradigm that needs significant studies before commercial entities adopt gpu use at scale. All-gpu solvers are starting to be developed, such as fun3d GPU[0], but features are very limited. GPU development is starting to catch up in the community, so it won't be long before a significant portion can operate heterogeneously or in gpu-only mode.

The amount of scientific work that could be done with such a machine would be staggering, specially if it can be local. I use 2-10k cores on a daily basis, having a dedicated machine with 1k would make debugging large scale problems much faster.

Yes, the cost is on the high side at the moment. It is impractical, but it may be the only choice we ever have if we do not want an internet connected vehicle.
