I came across a page on Hacking the Kinect. It was discussing how to interface with the system. The code I used is as follows.
The script comes from Lady ada in her post on hacking the connect.
I would love get this working. I am using python
This is a link to that code
http://learn.adafruit.com/hacking-the-kinect/fuzzing
The errors I get are as follow
sudo python UsbFuzzer.py
Traceback (most recent call last):

usb.core.USBError: [Errno 16] Resource busy
The main problem here is that libusb is returning an error code, "Resource busy". This could be a permissions problem. Try running your program with sudo and see if that fixes it. This link looks promising, because it talks about how to set up a udev rule so you don't have to run as root:
pyusb: cannot set configuration
If that does not help, you could Google around for "libusb resource busy".

I have recently tried to install and get working a program developed to use with a telescope. It is called hubble-pi and can be found here. https://github.com/RemovedMoney326/Hubble-Pi
The program runs but when i click the capture button I get this issue. I have reached out to the dev but he has not replied and that was over a month ago. If anyone could assist in figuring out a solution that be awesome.
Im a beginner when it comes to python so be easy. This is also happening on boot up as this is the first thing im doing when turning on my RPI. I am running this on a RPI 4 2gb.

I have 2 servers. I am attempting to setup one for continuous integration for my main website server
Web server 1(cloud-hosting):
Python3.6
Django3.1
Ubuntu16.04
Webserver 2(VPS):
Python3.7
Django3.1
Ubuntu16.04
Jenkins
--ShiningPanda(plugin)
Im new to web development, so if it seems odd as far as my web server types, that is why. I have been following along in the book Test Driven Development with Python. My issue is that when running python manage.py test [app] My [app] inherits from the class StaticLiveSever to generate a testing environment. On webserver 1, this works fine. On webserver 2, i get an error that the request address cannot be assigned. I use jenkins to build the environment, but the error i get is OSerror[99]:cannot assign requested address. I dont understand why this is happening when i run the same commands in Web Sever 1. It runs fine. Although again, the commands are run by jenkins and jenkins is configured to run python3.7

Hopefully the tracebacks above are not too confusing. Ultmiately what i did notice was the when im in webserver 2, i access the Django testcases.py module that has LiverServerThread and hardcode host=0.0.0.0 instead of host=localhost (1st traceback). The connection is then made although then the problem lies with geckodriver and the same thing (2nd traceback). I need to hard code ip 0.0.0.0 to be able to establish a connection, but then geckodriver is just listening, which i am assuming, at a completely different location (no error.log shown here).
So 1st id like to at least be able to make a connection to run the LiveServerThread class properly. Then try and resolve the issue with geckodriver. I also was not sure if the type of servers im running on poses as the problem.
When running either command:
sudo serverless package or sudo serverless deploy
I get the following traceback:

I’ve created several different projects and they work locally but they never progress beyond this invalid cross-link device Error when trying to deploy or package.
What are my options?
Edit: I tried nuking my virtualenv, uninstalling/re-installing serverless-python-requirements, deleting/re-pulling the lambci/lambda Docker image, no dice.
Then, I stumbled on this GH issue. As hinted in it, the experimental Docker feature Use gRPC FUSE for file sharing seems to be the cause. I've switched it off in the Docker Preferences for now and deploys are successful.
I just had a similar problem. See this issue for a possible solution.
In summary,
Remove all cached packages in /Library/Caches/serverless-python-requirements/
Remove existing docker image lambci/lambda build-python3.8
This is the error I get in VSCode when running docker-compose.

This error only happens on one of my 3 machines, so I have no idea what causes it. Resetting to factory defaults or reinstalling docker and vscode doesn't help. Without docker compose the image is pulling and then working fine. All the machines are on windows 10 and latest stable docker installed.
Here is the issue I opened on github. It appeared that this behavior only occurs in VSCode powershell console, but not in regular powershell console. The solution with changing encoding suggested there didn't help.
Solution: Update to 1803 on Windows 10. If you can't update, use external command prompt.
The same thing happens to me with Python scripts. Apparently, this is a Windows Update issue:
https://github.com/Microsoft/vscode/issues/36630#issuecomment-359969098
Edit: My workaround due to my company restricting updates is to use external terminal in VS Code

As obvious,
I am using Windows 7, and have:
Python 2.7.3
JDK
Android Emulator
Device drivers for my Sony Tipo.
Please help!
By the way,
I would prefer to get this running on my phone first. I am thinking of moving to the emulator later(after the tutorial is completed).
Is this question more suitable for https://android.stackexchange.com/?
I am not sure if this is still an issue for you, but I ran into the similar issue recently and managed to solve it so I will just leave a note here.
If anyone gets this kind of error, go to pgs4a folder and android-sdk folder. There, run SDK Manager.exe file. You will see a list of Tools and different android versions. Try to find the version that you are working on and install everything that is 'uninstalled'.
I managed to solve the above issue by installing everything under my current AND previous Android versions. Hope this will help anyone who ran into the same issue!
rename the folder android-sdk-windows to android-sdk
