A small app that allows a user to create an anonymous document with a unique ID. The document is discoverable by the ID. An MD5 hash is used so that the chances of collision are low and the chances of random discovery are low. The input is sanitized to prevent attacks on other users and the path is also sanitized to prevent browsing a poorly sec…

A small bit of kvetching...
Imagine in Shakespeare if a sonnet didn't hew towards the core message but instead had you hold all the loose blocks of marble in working memory.
My mistresses eyes are like the sun in no way, but in the way they are not like the sun so is her hair like wires, and in the way they are like the sun there is nothing further to remark upon.
By a similar quality it bugs me when early out conditions are deferred to the end of a code block. For me this is probaby a carry over from working in assembler. In early programming environments there was both a computational and cognitive cost to jumping around a block of other code prior to ceding control. Modern compilers optimize this away but there's still a cognitive burden to having to hold a larger model in mind. If you think of a piece of code as a tree of branching possibilities then it makes sense to whittle away those branches as quickly as possible so that you're left with the minimum functionality needed to close out the responsib
