The IMDb of music! They actually have a reputation system apparently. And sneaked in a vinyl marketplace as well.

The website name sounds like play on words: disc + hog, with hog in the sense "memory-hog", i.e. something that consumes all your computer's memory.

Mentioned e.g. at: videocardz.com/newz/amd-begins-rdna3-gfx11-graphics-architecture-enablement-for-llvm-project as being part of RDNA 3.

Intuition, please? Example? mathoverflow.net/questions/278641/intuition-for-symplectic-groups The key motivation seems to be related to Hamiltonian mechanics. The two arguments of the bilinear form correspond to each set of variables in Hamiltonian mechanics: the generalized positions and generalized momentums, which appear in the same number each.

Seems to be set of matrices that preserve a skew-symmetric bilinear form, which is comparable to the orthogonal group, which preserves a symmetric bilinear form. More precisely, the orthogonal group has:and its generalization the indefinite orthogonal group has:where S is symmetric. So for the symplectic group we have matrices Y such as:where A is antisymmetric. This is explained at: www.ucl.ac.uk/~ucahad0/7302_handout_13.pdf They also explain there that unlike as in the analogous orthogonal group, that definition ends up excluding determinant -1 automatically.

Therefore, just like the special orthogonal group, the symplectic group is also a subgroup of the special linear group.

There is only a very fine difference between a very good film, and the best films of all time. Perhaps it is something to do on how epic the subject matter is? It is often very hard to tell, and switches between the categories are also possible.

Critique of Harvard by Sean Carroll. Applies to basically all universities.

Maybe they did try once though: Harvard Project Physics.

Logarithm of a discrete groups.

NP-intermediate as of 2020 for similar reasons as integer factorization.

An important case is the discrete logarithm of the cyclic group in which the group is a cyclic group.

Ah, Ciro Santilli loved this one... games young Ciro Santilli played.

And as a result, adult Ciro really enjoys tool-assisted speedruns of the game.

Low budget.

Good theory of Jesus.

Yet another awk-like domain-specific language to do things from the CLI in a ridiculously short humber of character? Oh yes.

Historian Alan B. Carr:

Man-made virus!

TODO: if we had cheap de novo DNA synthesis, how hard would it be to bootstrap a virus culture from that? github.com/cirosantilli/cirosantilli.github.io/issues/60

Is it easy to transfect a cell with the synthesized DNA, and get it to generate full infectious viral particles?

If so, then de novo DNA synthesis would be very similar to 3D printed guns: en.wikipedia.org/wiki/3D_printed_firearms.

It might already be possible to order dissimulated sequences online:

TODO what's the point of it.
