2021.10.24 10:43 userluigi Nintendo Switch Joy Stick Broke Off
Last night I accidentally dropped my Switch after falling asleep, and the joy con stick fell off because of a 2 ft. drop :/. The white piece of plastic seems to be cracked and bendy, and I think I cannot push it back in and use it, because it feels like a way to make the joy con even worse.
If this ever happened to you or if you know how to fix it, please tell me how.

2021.10.24 10:43 Kdub1212 Any recommendations for online mba using gi bill?
I’m getting close to finishing up my bachelors and have been doing a lot of googling looking for an online masters that’s accredited and has decent tuition rates. Was hoping to find one that didn’t require gmat/gre score, with tuition less than $500/hr, and is aacbs accredited. Also one that doesn’t require taking additional business prereqs if bachelors wasn’t in business. Turns out that’s a lot harder than I thought. I live in Kansas and none of the school here really have what I’m looking for and the vast majority of colleges elsewhere have much higher out of state tuition costs. Figured someone here might have a good recommendation?
Oh yeah, price of tuition is important because I’m using mgib and don’t really want to have any out of pocket costs.

2021.10.24 10:43 Austenandtammy [article] TLB and Pagewalk Coherence in x86 Processors
Since the 386, x86 processors have supported paging, which uses a page table to map virtual address pages to physical address pages. This mapping is controlled by the operating system, which gives user applications a contiguous virtual memory space, and isolates the memory spaces of different processes.Link: https://blog.stuffedcow.net/2015/08/pagewalk-coherence/
Page tables are located in main memory, so a cache (TLB: Translation Lookaside Buffer) is needed for acceptable performance. When doing virtual to physical address translations, the TLB maps virtual pages to physical pages, and is typically looked up in parallel with the L1 cache. For x86, the processor “walks” the page tables in memory if there is a TLB miss. Some other architectures throw an exception and ask the OS to load the required entry into the TLB.
The x86 architecture specifies that the TLB is not coherent or ordered with memory accesses (i.e., page tables), and requires that the relevant TLB entry (or the entire TLB) be flushed after any changes to the page tables. Failing to invalidate would cause the processor to use the stale entry in the TLB if the entry is in the TLB, or a page table walk could non-deterministically see either the old or new page table entry. With out-of-order processors, relaxing coherence requirements allows the processor to more easily reorder operations for more performance.
But do real processor implementations really behave this way, or do some processors provide more coherence guarantees in practice? One particular interesting case concerns what happens when a page table entry that is known not to be cached in the TLB is changed, then immediately used for a translation (via a pagewalk) without any invalidations. Are real processors’ pagewalks more coherent than required by the specification (and does any software rely on this)? And if pagewalks are coherent with memory, what mechanism is used?

2021.10.24 10:43 zippyzappy01 Exchange Student Spring 2022 course recommendations
I am coming to UNC for the coming spring semester as an third year exchange student from Germany. Looking through the Course catalogue, I feel a little overwhelmed by all the possibilities. I am studying Economics back home and will take probably take two ECON courses (thats the maximum for exchange students) and two/three courses from any other department. At the moment ECON 384 (Gateway to PPE), ECON 455 (Environmental Economic Theory) and ECON 460 (International Economics) are at the top of my list. Do you guys have any experience with those classes or other intermediate ECON classes that are better? Any No-Go classes in ECON?
For the non-ECON courses, I am thinking about doing POLI classes and/or classes that provide unique insights into the US but I am generally very open for any class that you can recommend for internationals or in general! I am not used to this degree of freedom in choosing courses and want to make the most of my semester :)
Thank you so much for help, this forum already provided me with a lot of infos and has definitely made me excited for my time at Chapel Hill! See you in January!
