问题 Is there a way to plot a set of figures one at a time without closing the previous figure, maintaining control of the UI, and keeping the figures open at the end? Perhaps using a more appropriate backend, or writing it using the OO style instead of the pyplot/pylab style used below? e.g. I know I can do plt.ioff() for i in range(10) plt.figure() arr = thisFunctionTakesTenSecondsToGenerateMyArray() plt.plot(arr) plt.show() which will wait for me to close the figure at every iteration I can

问题 I'm trying to implement a way to communicate with my backend-server and be sure that my backend only answers, if it's my application which is calling. So my idea is, that i just send the SHA1/MD5 fingerprint with the HTTPS POST request and verify it on the backend server. If the fingerprint matches, the server will answer. So my first question is: How do I get these programmatically at runtime? Is it even possible? The second question is: Can it be that easy? Or do i really have to set up an

问题 I am not familiar with user authentication in Node.js, now I am trying to create a website with a login system. I have managed to make it work using the code snippets from the website, but I don't really understand why we need the passport.js as a middleware to do the authentication.

问题 I'm currently using Eclipse that came with Android Development bundle and following the GAE tutorial: https://cloud.google.com/developers/articles/how-to-build-mobile-app-with-app-engine-backend-tutorial I never had any server or backend experiences and I am hoping to make a Android application using features of the App Engine. Everything seems to be going smoothly following the tutorial until I got to the part where you need to "Create an upload script". I have no idea how I should proceed
