>>5183 (OP)
Thanks, I post here infrequently, and some other chans but rarely. I spend most of my time these days wandering the sweet streets of Holland and listening to cringey working class music while I pursue grad studies in optimization https://youtu.be/Pfs9A-THWoU (tip: Europe will let you bypass the BSc requirement for gradschool)
I also apologize for my persistent clobbering of commits but there's reasons for it: DMCA takedown notices and shit, tons of errors in material with no errata and I rage delete, or they got paywalled. I once had full access to all CMU lectures (don't ask how), and I did the entire 15-122 class and their compiler class, which was absolutely excellent as the guy teaching both was Rob Simmons (currently on sabbatical) and is great, and the lectures covered far more than the pdfs/slides but unfortunately I sperg'd and spread these too early and my access got cut off before I archived. These days I archive each course, do it to make sure it's worth doing, then post it on my shitty meme list. Remember the MIT prof who had all his OCW lectures deleted because he turned out to be a pervert or something so if you're doing these, get all the material first on your local storage then start doing it if you can.
I honestly thought about contacting Stallman and perhaps coming up with some kind of GNUniversity. A totally free, very theory based curriculum that anybody can access with a phone and a piece of paper but so far CMU has covered that but at anytime all these lectures and notes/labs could get paywalled so get them before they are gone.
The main updates were I jacked all the labs for 15-150 and 15-210 which I had done before but lost because again I foolishly didn't archive shit. I also added Convex Optimization, Stats Theory, and a crash course in analysis and Linear Algebra for grad students. Optimization is pretty easy, it's heavily used in 'operations research' which is this crazy PhD track where they hire you to solve traffic problems in major cities. Tip: write algorithms that optimize, offer them for rent on Algorithmia marketplace, collect money.
Also I may have to delete Open University as their shit new CEO totally fucked it up by jacking tuition and enrollment plummeted so their future is uncertain, after 40 FUCKING YEARS of stability. The absolute state of the UK. A cheap applied math undergrad is pretty much impossible however if you weasel yourself into some kind of customer service role at say, Elastic Search, you can go to Belarus or Germany and take university FOR FREE. Yes, it's (well, almost) free. And taught in english! We get fucked here with our scheming universities jacking tuition into the stratosphere. Cost of living in East Germany working class areas is cheap too. If you're PST/EST timezone go on flexjobs, weworkremotely, jobspresso, ect and just find any remote job. Don't tell them you're moving. Do this from Belarus or Germany as you take a Bachelors in Mathematics or whatever you want. Germany also lets you work during your degree, and even just hands you citizenship after if somebody sponsors you with a work visa which is easy to get.
There's some things I need to add, like this UI design course I liked (recorded lectures) http://www.cs.cmu.edu/~bam/uicourse/05863fall17/schedule.html plus some other 'software engineering' resources. Now that I don't solve untractable problems with stochastic optimization algorithms in a lab I've been making money deploying hacked together services while in grad school and reading about the whole industry of software management is interesting, though also kind of ridiculous.
