comment An alternative definition of pseudo-coherent complex
You're right. Beyond that, you need the full definition of pseudo-cohernce.

comment An alternative definition of pseudo-coherent complex
Your definition is the standard one. The idea is that on non-noetherian schemes $D^-_c$ does not behave well, so the notion of pseudo-coherent is a good substitute.

comment How to prove that any perfect complex on an affine scheme is strictly perfect?
@DylanWilson post this as an answer. This is exactly what I would say.

comment Stable vector bundle Projective or Injective?
The Ext sheaves correspond to a property we may call "internal projectivity" (exactness of ext-sheaves in the first variable), which is indeed a property that holds for vector bundles on schemes.

comment Reference for homotopy (co)limits of (co)chain complexes via totalization of double complexes
Strictly speaking, I don't know. However the fact that it is functorial and gives a complex quasi-isomorphic to the true colimit gives a hint in this direction. In any case, it should not be difficult to prove it.
