I am following a tutorial (https://levelup.gitconnected.com/simple-application-with-angular-6-node-js-express-2873304fff0f) on creating an app with Angula CLI, Node.js and Express. I use a proxy to start the app, the file defining the proxy looks like this:

I am using a k-modes model (mymodel) which is created by a data frame mydf1. I am looking to assign the nearest cluster of mymodel for each row of a new data frame mydf2. Similar to this question - just with k-modes instead of k-means. The predict function of the flexclust package only works with numeric data, not categorial.

A short example:

Actually I have an monolithic spring boot app with gradle and I want to covert it into multi module. It just a simple app to do CRUD book.

My app structure like the following,

I've been experimenting with nearest neighbor algorithm for images with the style presented in this post (i.e. goal is to see how many nearly similar images there is). After getting the example adapted to my case running, I have seen couple of times the error "lmdb.BadRslotError: mdb_txn_begin: MDB_BAD_RSLOT: Invalid reuse of reader locktable slot" , and wondering what is the cause?

My hypothesis is that it was caused by opening the (same) lmdb twice in the same run (at least it hasn't appeared since fixing that), but not totally sure. One of the few search hits is given in another forum, but the answer is not definite.

So the error came from the .begin statement:

I got the Firestore emulator up and running using this example. With the old Datastore, the local website was hosted on localhost:8080 and the admin server (where you could see the database entries) was hosted on localhost:8000. How can I see the local database entries with the new Firestore emulator?

I am trying to play around with deploying Flask application. When I run the code using docker swarm on Amazon's EC2 I started to get following errors:

Error message:

I have a LoginPage.xaml that inherits PageBase.xaml. LoginViewModel is the ViewModel for LoginPage and it inherits BaseViewModel. BaseViewModel has Func delegate defined - OnModalNavigationRequest which is subscribed by PageBase in it's OnAppearing method and implementation is provided in HandleModalNavigationRequest method. When Login Button is clicked on LoginPage.xaml, OnSubmit method of LoginViewModel, bound through command is invoked which, on successful authentication, calls NavigateToModal method of BaseViewModel. NavigateToModel method of BaseViewModel invokes HandleModalNavigationRequest method of PageBase on Func delegate OnModalNavigationRequest after checking if it is not null.

My problem is OnModalNavigationRequest is always coming as null, indicating that there is no subscriber to it. That means OnAppearing method of PageBase is not getting called which implies that PageBase is not getting instantiated. How to resolve this issue?

I'm posting the code of sequence of events that is taking place:

I am building a personal webpage with Mithril JS by following the simple application example in https://mithril.js.org/simple-application.html and the layout example in http://lhorie.github.io/mithril-blog/better-templates-with-fp.html. But I keep running into an infinite loop with a component that needs to load data from a file.

The layout component doesn't loop if I pass an inner file-loading component to it via "vnode.attrs". However, it loops if I build the layout component using the inner component in a function. I'm unable to understand the difference.

Failing example:

hello.json

I would like to run SQL queries to BigQuery using Python, I am a complete beginner at this. I have read the 'Create A Simple Application With the API' page (https://cloud.google.com/bigquery/create-simple-app-api#bigquery-simple-app-build-service-python) and have got my code as follows:
