Designing better file organization around tags, not hierarchies
Excerpts from introduction:
"Computer users organize their files into folders because that is the primary tool offered by operating systems. But applying this standard hierarchical model to my own files, I began to notice shortcomings of this paradigm over the years. At the same time, I used some other information systems not based on hierarchical path names, and they turned out to solve a number of problems. I propose a new way of organizing files based on tagging, and describe the features and consequences of this method in detail.

Speaking personally, I’m fed up with HFSes, on Windows, Linux, and online storage alike. I struggled with file organization for just over a decade before finally writing this article to describe problems and solutions. Life would be easier if I could tolerate the limitations of hierarchical organization, or at least if the new proposal can fit on top of existing HFSes. But fundamentally, there is a mismatch between the narrowness of hierarchies and the rich structure of human knowledge, and the proposed system will not presuppose the features of HFSes.
existing alternative systems like Git and Danbooru bypass HFS problems to deliver a better user experience. Then I describe a step-by-step model, starting from basic primitives, of a proposed file organization system that includes a number of desirable features by design.
I care most about the data model and less about implementation details. For example in HFSes, I focus on the fact that the file system consists of a tree of labeled edges with file content at the leaves; I ignore details about inodes, journaling, defragmentation, permissions, etc."

WE_Coyote73 comments on Lawsuit: School officials forced 12-year-old who killed herself to hug bullies
> Up until the early 90's it was relatively easy for school administrators to deal with bullies by means of suspensions and expulsion for continual behavior. Then the lawyers started getting involved and started suing school districts and principals. They argued, among other things, that even violent students still had a right to an education and that out-of-school suspension/expulsion deprived them of that right. They also argued that because they are public school students the rights to procedural due process applied to them. The courts agreed with these and other arguments. The result was that it became exponentially more difficult to suspend/expel a student. For instance, in most cases it can take up to a year or more to expel a student from an individual campus due to the various procedures and hearings that have to be held in order to comply with the right to procedural due process and if the district loses the case they are on the hook not only for their legal expenses but also the expenses of the student.

Teach Yourself Programming in Ten Years
Walk into any bookstore, and you'll see how to Teach Yourself Java in 24 Hours alongside endless variations offering to teach C, SQL, Ruby, Algorithms, and so on in a few days or hours. Similar results come from replacing "teach yourself" with "learn" or "hours" with "days."

The conclusion is that either people are in a big rush to learn about programming, or that programming is somehow fabulously easier to learn than anything else. Felleisen et al. give a nod to this trend in their book How to Design Programs, when they say "Bad programming is easy. Idiots can learn it in 21 days, even if they are dummies."
