ExpressJS router normalized/canonical urls
I'm after normalized/canonical urls for SPA with ExpressJS server. Although it is SPA that is backed up by server side router - templates can differ a bit for app urls. One of the differences is <link rel="canonical" href="https://example.com{{ originalPath }}"> tag. Not the relevant detail but explains the context of the question. I expect that there will be only one URL that responds with 200, its variations are redirected to it with 301/302 (works for living humans and search engines). I would like to make the...

So I load 3 scripts by executing a function that's called after document loads. This is the code: The problem is that it doesn't always work, nor always fail.

Go To Controller shows “Unable to find a matching controller.” error
In VS 2015, for my Web.API project, I installed MVC 5 from nuget via npm. This installation added references and generated web.config file under Views folder. I added new Controller with generated CRUD functions. When I right click and go to View on action it goes with no problem. But reverse action does not work. If I navigate to view via browser it works as well. Web app compiles as well. Is there any way for me to fix this navigation...
Why does Android select AppCompat components when I don't declare them explicitly?
I was debugging my App and found while hovering on an ImageView reference that, it is an AppCompatImageView instead of an ImageView. The same happened with a TextView(with AppCompatTextView). While I don't particularly have a problem with this behavior because its AppCompat after all but when inspecting the code of fellow developers, I saw, extends Activity instead of AppCompatActivity and I almost marked it as a "bad practice"....

Saving tf.trainable_variables() using convert_variables_to_constants
I have a Keras model that I would like to convert to a Tensorflow protobuf (e.g. saved_model.pb). This model comes from transfer learning on the vgg-19 network in which and the head was cut-off and trained with fully-connected+softmax layers while the rest of the vgg-19 network was frozen I can load the model in Keras, and then use keras.backend.get_session() to run the model in tensorflow, generating the correct predictions: frame = preprocess(cv2.imread("path/to/img.jpg") keras_model = keras.models.load_model("path/to/keras/model.h5")...
