问题 I am learning iOS programming and am confused by the following code regarding the use of keyword self. From my understanding, self is like Java's this . It refers to the current instance. When I want to call a class method, the usual way should be like [PlayingCard validSuits]; But it's also OK to invade a class method on an instance, right? Like [self validSuits]; (I am in the class so self refers to an instance of PlayingCard) But in the following code, it gives error somewhere but looks ok

问题 I get this error message from time to time (not every time) I compile (EDIT: sorry, I didn't make myself clear here: I actually meant "rebuild") my mixed-mode project. And Visual Studio tells me to "recompile with a command line option of '-Zm114' or greater". In principle no problem, I just do as VS tells me. But currently, there are two problems with this: Why does it not occur every time I do a rebuild? If I understand correctly, the compiler ran out of memory while compiling my project.

问题 I know this is difficult because of how Javascript works and "everything" may be possible. But I'm tired that errors frequently occur and are not noticed until I run my code and everything crashes or returns errors because I wrote a typo in a variable or on a function. My fear is that a crash is the best I can hope for, some errors may not be noticeable immediately and send a "valid" undefined value that causes some subtle errors that may sneak into production. Is there any tool that helps

问题 I am trying to get NVIDIA's CUDA setup and installed on my PC which has an NVIDIA GEFORCE RTX 2080 SUPER graphics card. After hours of trying different things and lots of research I have gotten CUDA to work using the Command Prompt, though trying to use CUDA in CLion will not work. Using nvcc main.cu -o build.exe From the command line generates the executable and I can run it on the GPU, however I have the following error when trying to use CLion: I believe this is the relevant part, however

问题 I'm learning C# and working with VS 2019 Community (16.6.5 ver) on windows 10. Everything was OK until today. Everytime i push ctrl+F5, (i run my codes this way) VS19 show me this Error, even for Hello World! program. I gave the Error code and description before. Here is what written under file tab in Error section: "Microsoft.PackageDependencyResolution.targets" 🔶 Maybe this helps: Today, for the first time i used a windows tuneup tool to do some cleanups.(360 Total Security) 来源： https:/
