system

问题 I would like some general info on system apps. I am working with a manufacturer who is willing to give me the info required to make my app a system app. However, I do not know exactly what this information should be and how to change with my app to make it a system app with the given information. I believe I need the something in my manifest like this android:sharedUserId="android.uid.system" and then I need to sign my app with the manufactures key? I am not sure could someone explain to me

问题 My code runs, however, if i change the order of the equations defined in my formula my graphs changes as well. Can somebody tell me why this is? Now i do not know what the right graph is from this system. def myFunction(r,t): g = 9.81 L_L = 20 #draught L_r = 20 #draught L_d = 4 #ukc u_s = 0.08 w_d = 60 #width vessel rho = 1030 b_R = 1.0 b_L = 1.0 b_D = 1.0 A_s = 340*L_L M_s = 40000*10^3 w_L = r[0] w_r = r[1] u_1 = r[2] u_2 = r[3] u_3 = r[4] u_4 = r[5] u_d = r[6] p_1 = r[7] p_2 = r[8] p_3 = r

问题 How would I capture the output from a php script that I run at the command line and store it to an array in c++? i.e. system('php api/getSome.php'); 回答1: Traditionally popen() is preferred when you need to IO between your parent and child process. It uses the C based FILE stream. It is a wrapper around the same low level intrinsics that also make up system(), namely fork + execl, but unlike system(), popen() opens a pipe and dups stdin/out to a stream for reading and writing. FILE *p = popen(

问题 I wanted to ask you if anyone knew how to check if a point was inside a given triangle, on a reference system in space. I am aware that speaking of 2d systems I can obtain this point with the following procedures: To determine if a given point v lies within a given triangle, consider a single vertex, denoted v0, v1 and v2 are the vectors from the other two vertices v0. Expressing the vector from v0 to v in terms of v1 and v2 then gives v = v0 + av1 + bv2 where a, b are constant. Solve for a,

问题 I have a problem with Snort, I've just installed the program on a R-Pi. 2 other computers on the same network can ping the R-Pi with success. However I had the idea that snort was able to be run in Promiscuous mode meaning that it can see all traffic in a local network... without needing to run it inline in the network. When i try ping the other two computers in the same network Snort does not pick this up. Changes i have tried.... Ruleset set to - alert icmp any any -> any any Config file

问题 In "Computer System: A Programmer's Perspective", section 2.1 (page 31), it says: The value of a pointer in C is the virtual address of the first byte of some block of storage. To me it sounds like the C pointer's value can take values from 0 to [size of virtual memory - 1]. Is that the case? If yes, I wonder if there is any mechanism that checks if all pointers in a program are assigned with legal values -- values at least 0 and at most [size of virtual memory - 1], and where such mechanism
