uplift | A playground for elevation on Android | Android library

I have the following dataframe:

I am working on a modest SPA that (will) use Firebase for Authorization and Firestore for the DB and Flask on the backend (It's not strictly a true SPA because things like contact page, terms, etc are on different pages). I have gone through tutorials such as Firenotes doc tutorial, and it looks like because it is a JWT instead of a session I have to authenticate with every request.

Question(s):

1. Is it considered best practice to validate on every request or should I log the user in and then store a session?

2. Even if I store the user in a session, I would still need to authenticate their JWT on any database call, so there is no uplift there is there?

3. Is there any concern about cloud costs with either approach?

I need to click twice on a button linked to the current page so i can get the data fetched from the api to render. I am using nivo / charts to visualize my data.

The component fetches the company list from the api, and a second fetch loops through every result fetching data for every distinct company.

On first try, the company list were to fetch on the parent component, and a fetch request would take place for every child component thereafter (parent=list of chart components, child=Company Chart), but on the pagination process it did not render properly so I had to uplifted the state to the parent component, the problem this time was that the parent component did not render on first click, I had to double click for example link button so that the parent component would render.

I thought the problem might be occurring since there might had been a missynchronization with the componentDidMount order of actions since I was sure that the first and second data fetching (first being the company get request and second distinct company get request), were executing simultaneously rather than one after the other. So I directed to redux and architectured my application to redux rules. It did not resolve anything and still requires to double click on a link so that the rendering would take place.

Now I feel like I would need to add some await/async rules for the api fetching process but I am not sure whether that would work or not, so I would really appreciate getting a second opinion on how to solve this little problem because it has been bugging me for weeks.

my Reducer:

I am doing a project with Kindergarten kids in Thailand to improve English. One of the things I want to do is measure "uplift" that a lecture brings to the students.

Teacher scores 3 students before the lecture, and then scores all students as usual after the lecture. For uplift, we want to measure the difference before and after using python / pandas.

I can split easily the big df to one per name (sample below)..

basically I want per row look up a name, and then look up the post lecture score in the column - row by row ( so end results is ie Pre Score and Post Score for that name in the row.

Just want the left hand cols and Pre and post score for the named student

a bit confused how to do...thanks

I need to scale values only within certain categories. Essentially I have a data.frame with individuals, years, and several predictors.

I need to scale my predictors within each individual and year, in other words standardize Individual A year 2013, Individual A year 2015 and so on for 33 individuals and 86 thousand rows. Not wishing to do this in separate data frames for each individual and year combination, I tried to use a dplyr solution

library("dplyr")

data %>%

group_by(Individual, Year) %>%

mutate(data, std_uplift= scale(uplift) %>%

ungroup()))

Naturally, this throws an error:

Error: Problem with mutate() input ..1.

x Input ..1 can't be recycled to size 1100.

i Input ..1 is data.

i Input ..1 must be size 1100 or 1, not 83670.

i The error occurred in group 1: Individual = "A", year = "2013".

I don't understand how to fix the error, as it seems to be trying to shove data from all individuals into a single group, but I am guessing that there is a better way to scale data given categories. How can I make this work?

Thanks!

I made a website for a friend's birthday. I used parallax for a nice scrolling effect to outline her rings. However, the rings are only centered when I'm on full screen (15" screen). The rings don't move when I resize my page. I want the whole parallax div to keep centered and move when the browser is smaller. The images don't resize either they just disappear behind the browser. I know that if I'm not viewing the page on my screen size, the page looks off. Any help would be appreciated, Thank you!

This is how it shows when the browser is smaller in width, pictures cut off and nothing moves.

I've been checking similar issues and haven't found any answer addressing what I am observing.

The issue is that I've easily managed to get Hypermedia in HAL format in my REST API when I retrieve 1 resource, but when I hit the controller methods retrieving a list of entities, then the hypermedia is NOT the same.

Here are the ouputs:

• single resource returned

  "_links": { "self": { "href": "http://localhost:8080/celsvs/api/books/123567891099" }, "books": { "href": "http://localhost:8080/celsvs/api/books" } }

• List of resources

  "links": [ { "rel": "self", "href": "http://localhost:8080/celsvs/api/books/123567891099" }, { "rel": "books", "href": "http://localhost:8080/celsvs/api/books" } ]

I started with Spring hateoas 0.25, but as I had to uplift anyway Spring boot and I saw that the Hateoas API had changed, I am now on Spring hateoas 1.0... And even after adapting my code to the new API I am still getting the same result.

I am using the RepresentationModelAssemblerSupport class to keep my controllers clean from code to generate hateoas content. So this is how it looks like:

I am in the process of doing some data wrangling and I have come across the following problem.

I currently have a function that's being called .onAppear that sets the state to a location name upon the user selecting it. That value is added to the Firestore query and gives results based on the selected location. My issue is that when the users select a different location, the function in .onAppear isn't called again. How would I go about structuring the code so that it runs the Firestore query again once State is changed? Below is the code from both the main view and the modal view.
