    Prove Endomorphism Ring of Simple Module is a Field

    I spent like 6 hours trying to prove that the endomorphism ring of a simple module is a field, helping my friend with his homework. Now I'm convinced that the result is not true. By Schur's lemma, all endomorphisms of a simple module (except 0) are isomorphisms, so it's a division ring, but I...

    Proving Module Homomorphisms: A x B to M & M to A x B

    If you can help, that would be great. Let R be a commutative ring, and A,B,M be R-modules. Prove: a) HomR(A x B, M) is isomorphic to HomR(A, M) x HomR(B, M) b) HomR(M, A x B) is isomorphic to HomR(M, A) x HomR(M, B)

    Has Linux Kernel Module Support Improved in Recent Years?

    [SOLVED] Linux kernel module support How is it these days? IMO this is one of major areas where Linux used to lag behind Windows. Loading/unloading modules during runtime was not always reliable and sort of a pain... has it been improved in the last year or two?
