问题 I am using LibGDX to make a game. I want to simultaneously load/unload assets on the fly as needed. However, waiting for assets to load in the main thread causes lag. In order to remedy this, I've created a background thread that monitors which assets need to be loaded (textures, sounds, etc.) and loads/unloads them appropriately. Unfortunately, I get the following error when calling AssetManager.update() from that thread. com.badlogic.gdx.utils.GdxRuntimeException: java.lang.RuntimeException

问题 Im' running this code on a Linux Red Hat with the sun/oracle JVM 1.6_23, inside a VMWare server. After some times the JVM seem to be unable to access my anonymous inner classes. My classpath is fine, since it works for a period. All i got is errors like this one : java.lang.NoClassDefFoundError : com/mycompany/impl/MyClassImpl$1 at com.mycompany.impl.MyClassImpl.markAsDeletable ( MyClassImpl.java :45). line 45 is the first line below, it can't find my new Predicate DomaineVO domaineVO =

问题 I'm working on some code which builds a buffer in memory and then empties it into a TextWriter when the buffer fills up. Most of the time, the character will go straight into the buffer (synchronously) but occasionally (once every 4kb) I need to call TextWriter.WriteAsync . In the System.Threading.Tasks.Extensions package there only appears to be a ValueTask<T> struct, and no non-generic ValueTask (without a type parameter). Why is there no ValueTask , and what should I do if I need to

问题 I am trying to read and write jpegs wth Adobe RGB colorspace in OpenCV. OpenCV assumes the jpeg has sRGB colorspace and when displaying or writing to file, the image loses some of its color intensity. I found this intensity loss was due to colorspace difference by answers given to my previous question. Is there anyway I can make OpenCV to read Adobe RGB colorspace without casting it to sRGB? 回答1: Some information that is hopefully useful for anyone looking for a work-around for dealing with

问题 I've been assembling (and disassembling) the BSWAP x64 instruction with both NASM and GAS, and both assemble the instruction BSWAP r15 as 490FCF in hex. Disassemblers also disassemble this to the same instruction. The REX prefix for the instruction ( 49 ) thus has the REX.W bit (bit 3) and the REX.B bit (bit 0) set. This is directly in contrast to the Intel documentation, which states: In 64-bit mode, the instruction’s default operation size is 32 bits. Using a REX prefix in the form of REX.R

问题 I use c++11 while I need some classes from c++17 library. When using boost from which classes were added I wish to do the following: #if __cplusplus < CPP17 using std::any = boost::any; #endif Such alias is not allowed. Also extending the std namespace causes undefined behaviour. I wish my code to look the same regardles of the c++ version. Is there a clear way? 回答1: The clear way is to add a customized name for it. #if __cplusplus < CPP17 using my_any = boost::any; #else using my_any = std:

问题 public static int[,] operator *(int[,] arr1, int[,] arr2) { int sum; int[,] res = new int[arr1.GetLength(0), arr2.GetLength(1)]; for (int i = 0; i < arr1.GetLength(0); i++) { for (int j = 0; j < arr2.GetLength(1); j++) { sum = 0; for (int k = 0; k < arr1.GetLength(1); k++) { sum = sum + (arr1[i, k] * arr2[k, j]); } res[i, j] = sum; //Console.Write("{0} ", res[i, j]); } //Console.WriteLine(); } return res; } Here i am trying to overload * operator to multiply two matrices.. but the compiler

问题 I'm running a docker-compose file we have, I usually run it with command: docker-compose up But today I'm getting this error. ERROR: failed to register layer: symlink ../bdf441e8145a625c4ab289f13ac2274b37d35475b97680f50b7eccda4328f973/diff /var/lib/docker/overlay2/l/7O5XKRTJV6RMTXBV5DTPDOHYNX: no such file or directory 回答1: To solve this issue, you just Stop and Start docker service from terminal. # service docker stop # service docker start 回答2: Followed this answer just restarting docker
