Below are the posts on this blogged sorted into their natural types.

# A computation a day

These posts are largely focused around just computing things, with little focus on background or intuition (outside of any very relevant to the problem).

A Computation a Day: Compactly Supported Cohomology

A Computation a Day: the Brauer Group of a Number Ring

A Computation a Day: a Pullback Pushforward

A Computation a Day: a (Harder) Pullback Pushforward

# Weird examples

These are usually very short posts writing down some sort of example of ‘weird’ behavior. These usually have very little in the way of background and/or intuition.

Weird Example: Pullback of Noetherian is Not Noetherian

Weird Example: Pullback of Very Ample by Finite is not Very Ample

Weird example: finite maps don’t preserve projectivity

# Short blurbs

These are just short posts about something random. Once again, no real intention of discussing background material and/or intuition.

# Expositions

These are usually longer posts, usually with the intent of giving an introduction and/or overview of a particular topic. These usually focus on giving sufficiently much background and intuition as to elucidate whatever their subject matter may be.
