I don't understand what you mean by this. Machine code itself abstracts away the underlying hierarchical memory structure. Sure, some machine language might have instructions to manipulate the cache, but those are easily invoked from C, using either inline assembly or __builtin functions.
> but objectively you can't identify which students won't do the work - ergo, you can't discriminate who to enroll
I'm calling complete bullshit on this one: isn't that the very definition of admissions? Even if you claim it's not, I think that if you look at any student's previous grades / work experience / references, you can quite reliably determine who will do the work and who will not.
These schools simply don't want to: they want to admit everybody so they can take their money in exchange for basically nothing. I would fully support legislation to bar for-profit institutions from receiving any federal tuition aid (whether loans or grants).
> public money[1] should not be involved. The school management can't say "no" to it
This is false: schools are not required to accept federal loans.[1]
You'd be very surprised at who won't do the work. I was. Interacting with them, and knowing how they were admitted, I have no doubt of their previous grades / work experience / references, and yet am time & again stunned at their utter reluctance to take basic required initiative.
By "won't do the work", I mean really simple things. A student has a week to take a simple on-line 10-question multiple-choice quiz, but doesn't even look at it. For every creative assignment, I make clear "submit something - even if it's just a text file saying 'I have no idea', I'll work with you on it", but nothing is submitted. I'll take a submitted "program" of pure gibberish, write a detailed explanation of what's wrong and how to make it work, tell them to fix it, and give them until the very end of the course to do anything & everything to make it passable, but no resubmission is attempted. Online group discussion participation is required with a weekly N-post minimum (N very small) with very low content standards, a very simple requirement, but little or no participation occurs. These are students who passed high school, hold jobs, can hold competent conversations, show up for class, etc.; I have no reason to doubt they have references, adequate prior grades, and work experience. Yet...when given a very basic collegiate task, they won't do it to a mere 60% sufficiency.
There's a fundamental difference between high school and college: the latter is not obligated to pass you. Every opportunity is given, every task may be simplified to near-triviality, but if the student won't take the steps on their own, they reap the consequences of willful inaction.
But, of course, you refuse this experiential insight and insist it's all about malicious greed.
This is false: schools are not required to accept federal loans.
You miss my point: it's not about rejecting federal loans, it's about rejecting an applicant who does satisfy grade/work/references/funding criteria when there are openings, but the admissions personnel concludes admission still isn't a good idea. The mortgage industry knows what I'm referring to.
I've seen and read the entire speech dozens of times: In school, I distinctly remember being given the entire speech transcription and talking about it as a class on more than one occasion. In elementary school, we would have an actor come on our "morning announcements" and re-enact the speech each year. One teacher showed it to us on YouTube in it's entirety.

IMHO, this is a huge advantage: it guarantees that the maintainer of the project can't run off and so something crazy. The linux kernel allows every author to retain copyright, and there's some security in that: since it is basically impossible to get clearance from even the most significant subset of copyright holders in the kernel, it will forever be GPLv2.
Look at it this way: if Torvalds were evil, he could require everybody to assign him copyright, and then take everybody's work and let corporations pay him to allow them to use it closed-source enviorments. Or even un-GPL the whole thing and sell it to somebody. (IANAL, obviously - not sure about that last one)
Point is, there is security in nobody having controlling ownership of a project,
Why the hell is CONFIG_PERF enabled in distribution kernels?? A normal server/desktop user would NEVER USE THAT. If you're smart enough to use Perf, you ought to be smart enough to compile your own kernel.
This is a brilliant example of how stupid many distros are with their kernel configurations. They need to start understanding that enabling features that nobody uses only increases the probability of problematic bugs.
Also, they need to stop enabling CONFIG_CC_STACKPROTECTOR. It slows stuff down, and as can be seen here, often doesn't do any good.
