Every object in git (commit, tree, revision of a single file) has a hash that is guaranteed unique within a repository (otherwise many more things than a web UI would break) and likely also globally. I can understand wanting to isolate repositories to prevent hash collisions from causing problems, but within a repo everything has a universally unique ID.

edit: for instance, that specific VERBS.md is represented by the blob 3b9a46854589abb305ea33360f6f6d8634649108.

that's not what i meant. i was trying to suggest that the string "blob" does not fit. why is it there? why is it needed?

    https://github.com/gritzko/beagle/a7e17290a39250092055fcda5ae7015868dabdb4/VERBS.md

this should be sufficient to represent the file.

"blob" is like a descriptor of the value that follows. it would be like doing this:

    https://github.com/user/gritzko/project/beagle/blob/a7e17290a39250092055fcda5ae7015868dabdb4/file/VERBS.md

this actually irks me every time i see it in a github url

> this should be sufficient to represent the file.

Except it's not, because the oid can be a short hash (https://github.com/gritzko/beagle/blob/a7e172/VERBS.md) and that means you're at risk of colliding with every other top-level entry in the repository, so you're restricting the naming of those toplevel entries, for no reason.

So namespacing git object lookups is perfectly sensible, and doing so with the type you're looking for (rather than e.g. `git` to indicate traversal of the git db) probably simplifies routing, and to the extent that it is any use makes the destination clearer for people reading the link.

They are following the /key/value/key/value pattern, but the first two pairs in a GitHub URL are fixed to user and project, which lets them omit the key names. I could see them not being willing to hardcode the third pair to blob.

Back when GitHub URLs were kind of cool, github.com/user/gritzko/project/beagle would have been much less cool than just github.com/gritzko/beagle.

They are not. There's just a routing layer below the repository.
