I have been getting comments about caches after my refterm series. Many people have said their CS teachers taught them not to write caches because they are "too hard"? And others have asked simply to go over how they work. I'll see if I can make a quick lecture on caches.https://twitter.com/wontruefree/status/1451008376251559939 …

I mean CS teachers probably also tell you to not write your own queue, ring buffer, dynamic list, etc (or basically anything at all probably)

I have an bachelor's in CS and this is not true. Entire courses dedicated to analyzing and implementing data structures were mandatory for my degree. I've far more often heard "don't write your own X" from people who write code for a living.

From what I have heard (I hear lots of stories, as you might imagine), the difference in CS educations is dramatic. Some places learn ASM. Other places never do anything outside of Java. Etc., etc.

Even if they only teach Java, I'd still expect courses on how data structures work which *should* at least include some implementation thereof. Otherwise they're not really teaching CS at all and the school is (IMO) lying to their students about what their degree means.

There are many schools where this is true, from what I have been told. This is not restricted to community colleges.
