all the pcie ones have their own memory on board.
 
You don't just get more cores on the host system, you need to make software that will run on that node explecity. The pcie cards run linux them selves, and you need to put the jobs on the cards.

What about just caching the files on the editors' machines? Instead of having the cache be in a centralized location, each workstation would have its own cache and you would also have less network traffic. I am not sure if Windows supports this but there may be some third party software to do it. The idea would be that when you attempt to open a file in the cache directory, if it does not exist (or there is a mismatch of last-modified time stamp) then Windows (or whatever third party software) would stream in the file, in its entirety or maybe in certain sized chunks, to the cache, and meanwhile also serve it to the file handle that is trying to read. As for the "in its entirety" / "chunks" this would mean that there would not have to be an explicit request by the application to read a small region, in order to go ahead and also load what is likely to be read next anyway since it's nearby the requested region. Although I'm not sure if Windows / certain file APIs used by the application already try to pre-load more data themselves and buffer it in memory.

I think you're misunderstanding the process, and they absolutely can expect people to spend that kind of time precisely because they AREN'T looking for an "average" set of candidates.  If you want to get in on a startup project like this that is already functioning with a company that has the kind of reputation and stability of LTT then you better expect to spend some personal time outside of work proving you have the chops.
 
Also, my understanding is that only the SELECTED APPLICANTS from the resume review were chosen to complete the coding challenge.  It wasn't an open invitation, you had to be selected by Luke based on your resume/application.  So it's no different than a code challenge for a major company, and given the desirability of working for LTT I'd say it's completely reasonable.
 
Heck, when I was interviewing for jobs last fall I spent several days being flown around and doing all-day interviews for prospective companies.  It happens, and candidates who are open to relocation won't bat an eye at that sort of thing.  I mean what if you needed a certification for a job and had to spend potentially weeks studying for it?  How is a coding challenge hard to make time for?

Personally I started with Lua and moved on to C, which worked out quite well for me. But if you are going to skip learning a scripting language and go straight to writing compiled code, I *highly* recommend that you avoid C++. Not because C++ is garbage or something, but rather because if you force yourself to do the scary stuff like pointer math and memory allocation, then you will get a much better understanding of the underlying concepts even if later on you decide to use C++ convenience features like vectors.
 
Once again I'm not hating on C++ or anyone who uses it, I just would highly recommend that a beginner start as close as possible to the "bare metal" and work upward, instead of starting at a very abstracted level and viewing the inner workings of everything as magic like what I see happening in many computer science courses. But hey, maybe that's just a reflection on my personality.

My Nvidia GTX 750 Ti manufactured by ASUS still (*crosses fingers*) works and performs quite well for what I need it to do. But after watching some Scrapyard Wars where Linus was complaining about people wanting to charge too much for old graphics cards I started to wonder just how much my card, which originally cost about $160 at the time of purchase, would be worth today. I'm not planning to replace my 750 Ti or sell it for any other reason, but just out of curiosity, what would be a fair market price for one of these? If it matters, I'm the the southeast United States.
 

 
Also, you've got to admit... for it just being a 750 Ti, ASUS did make a really awesome-looking cooler for it.
