问题 I am currently working with android source tree. For my work I need to go through the instruction at run time. Previously when I used Dalvik VM I hooked into by enabling the interpreter mode and going through the following file dalvik/vm/mterp/out/InterpC-Portable.cpp . There is a loop that continuously cycle through the instructions. I want to find something similar to this for the ART runtime. What files should I modify? Do I need to change something like enabling interpreter mode as I did

问题 Hello, I am trying to setup Android Studio 3.1.3 in a guest VM with windows 10 x64 pro. In the VirtualBox I have intel HD sound controller enabled. I have installed Android 6.0 in AVD for ARM EABI architecture on a Pixel.

问题 Im not sure if im understanding vagrant correctly but to my understanding its like a server running in a VM on your computer, which you use instead of your localhost to check to see if stuff is working because your local setup is slightly different to your servers. However is the quickest way to check updates, to git push from your local pc, then git pull on your vagrant VM then load up the website on your local pc to see changes, seems like it would become a painful process after a while

问题 We got a weird error event last night where a GCE VM instance got terminated by the system for reasons that are unclear. Is there any way to identify why a running instance got terminated? Portion of the REST response from the GCE service: { "kind": "compute#operation", "operationType": "compute.instances.guestTerminate", "status": "DONE", "statusMessage": "Instance terminated by guest OS shutdown.", "user": "system", } 回答1: In this case, it appears that your instance's guest OS itself was

问题 I logged in to my GCE VM instance (Debian) and installed ufw and enabled it. However, I forgot to enable port 22. Is there another way to log in so that I can enable port 22 without having to destroy the instance? 回答1: No, the only way to access to the instance is through SSH. You can enable the port 22 using a startup script like the following one: #!/bin/bash /usr/sbin/ufw allow 22/tcp Then, you can add this startup script to your instance either using the Developers Console and pasting the

问题 any help appreciated: I'm a bit confused with the fact that when I add a reserved IP to a cloud service, the IP address matches the one reserved. When I do the same but add an instance IP address to a certain machine, it only adds a random public IP address to the machine, and changes the name accordingly to the one reserved but the IP address does not matches the one reserved. Any ideas? This is my reserved IP ReservedIPName : name Address : XX.XX.11.119 Id : AA Label : sipserver Location :

问题 I'm trying to run an application that I've developped recently. This one uses an ODBC connection to browse a defined database. I'm trying to execute this app from a remote computer.

问题 I have a Powershell script where I need to get the operating system for various servers. Up until now I've been using WMI in order to accomplish this task, however I've read about how WMI can get timeouts, so I was wondering is there another method of getting the operating system of a server? Here is the code that I use at the moment and want to change in order to avoid WMI: $serverVersion = Get-WMIObject -computer $server -class Win32_OperatingSystem 回答1: You will probably find what you are
