That isn't true; a git repository isn't just a single file. It is one (or many) pack and object files, and it's possible to have a repository by using each push (which may be multiple commits) to store a new pack file rather

There is no ".git" file. It's a directory with a lot of files. Some of the packing has been storage optimisations but the logical model (objects identified by hash) has remained the same throughout. The nice thing about this

JUnit was created by Kent Beck et al to support automated testing with what came to be known as XP and subsequently TDD. This inspired subsequent testing frameworks such as TestNG and implementations for other languages like nUnit.

LLVM bitcode is still architecture specific - for example, whether the code is 64 bit or 32 bit will result in different bitcode paths. You may be interested to look further into Eclipse OMR, which is a generic VM used by IBM for many of th
