问题 I was trying to add an APK in AOSP version 10 as system application. I have followed the procedure mentioned in almost different links which is here Add apk in AOSP but nothing worked. The process mentioned in this link and the steps I followed are: Put my Apk in Aosp_root/packages/apps/my-app-folder/my-app.apk Write Android.mk of my-app.apk in /my-app-folder Code of Android.mk LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE_TAGS := optional LOCAL_MODULE := Signal LOCAL

问题 How can I determine the OS type, (Linux, Windows) using Powershell from within a script? The ResponseUri isn't recognised when this part of my script is ran on a Linux host. $UrlAuthority = $Request.BaseResponse | Select-Object -ExpandProperty ResponseUri | Select-Object -ExpandProperty Authority So I want an If statement to determine the OS type that would look similar to this: If ($OsType -eq "Linux") { $UrlAuthority = ($Request.BaseResponse).RequestMessage | Select-Object -ExpandProperty

问题 This is probably a very basic question, but I'm using the code below to run a simple alarm. It works as I want it to, but I'm wondering if it's at all possible to run multiple alarms simultaneously that each trigger a different function when complete. Is there a way to do that? #include <signal.h> #include <sys/time.h> #include <stdio.h> #include <time.h> void alarm_handler(int signum){ printf("five seconds passed!!\n"); } int main(){ signal(SIGALRM, alarm_handler); alarm(5); pause(); return

问题 I write some code to make my own operating system and study x86 assembly language, too. While studying x86 assembly language, I start wondering about interrupt. Look at below assembly code: mov ah, 2 mov dl, 'A' int 0x21 This code prints 'A' to the screen. it is for MS-DOS. mov eax, 1 mov ebx, 0 int 0x80 This code makes program to exit. it is for Linux. The last one: mov ah, 2 mov al, 1 mov ch, 0 mov cl, 2 mov dh, 0 mov dl, 0 int 0x13 I wrote this code to copy kernel code from disk. This code

问题 Is it possible to see files with certain extensions with the os.listdir command? I want it to work so it may show only files or folders with .f at the end. I checked the documentation, and found nothing, so don't ask. 回答1: glob is good at this: import glob for f in glob.glob("*.f"): print(f) 回答2: Don't ask what? [s for s in os.listdir() if s.endswith('.f')] If you want to check a list of extensions, you could make the obvious generalization, [s for s in os.listdir() if s.endswith('.f') or s
