High end databases are often run directly on block storage. The db already manages allocation and caching so a filesystem just adds overhead and wonky semantics.
And therefore your nitpick that a database will consist of files is wrong. (not to mention that the article is not about files as an implementation detail, but as files about a user interface)
What is this magical "high-end" database that operates without the use of any "files"? Certainly not Oracle or Sybase. Sure, they have "data partitions", but the database executables are distributed and stored in files. And what is the magical file-less operating system that they run on? Ooooh we're in "files are extinct land". Where nothing needs files.
This is not an example of someone being fired for saying or believing that there are two genders. This was someone deliberately misgendering and ungendering a trans boy (not non-binary) in class after having been ordered to stop.
The teacher felt strongly that the student's gender was biological and not something the student could arbitrarily choose to change. The teacher felt that using a pronoun other than a biologically consistent one was "lying", and it was against the teacher's religion to lie, so the teacher would not use the student's chosen pronoun. Did I miss something?
Your response to my comment was flagged, but you seem to be laboring under some misconceptions here. While biology is what it is, the mapping from biology and other factors to social categories is determined purely socially. Categories and labels are not true or false, they are socio-political processes that can uplift or oppress minorities just like other such processes.
I don't know what really happened but assuming he just refused then I assume that will in the future more been like a teacher who refused to stop calling his black students negroes than an example of PC hysteria.
My point, albeit made sarcastically, is maybe some people just like to walk slowly. I was taught as a young man that walking slowly is a sign of wisdom and confidence. It means you know where you are going, you left on time, and you're not in a hurry.
Java Spring documentation also claims to support the question mark vs. asterisk character, however it seems that some versions treat them identically, where the ? is supposed to be a random value and the asterisk is supposed to mean every value...
