appy | A functional wrapper around Fetch API | Functional Programming library

This is an example we can work with:

I want to take an image, then turn it into 9 different images that I add to a list. I want to take this single image, then change the R value by a large value, then the R value by a half, and finally change R by a smaller value.

I'm struggling to get this to work though. My logic loop doesn't seem to work, and my images and not being modified. Any help appreciated.

I am making a calculator app and want to update history in second fragment but not able to find a perfect solution for updating ListView in second fragment. I tried many solutions but none of them worked properly. I'm using ViewPager to swipe between calculator and history fragments. I tired bundle class but if I use bundle in OnCreat method of first Fragment(CalculatorFragment) with ViewPager it shows me blank screen after starting an App & if I use Bundle class in Equal Button it crashes app. here I am passing id of viewPager as Container of fragments.

I seen many answer perfectly working when they are using Framelayout for the container of Fragments but I want to keep swipe functionality of ViewPager, I tried many solutions but none of them worked properly with ViewPger, I added SharedPreferences to my code but it is not updating (not live) when I am using calculator. SharedPreferences seemed to work but they are not updating History when App is Running And When I restart the app it shows me my last Calculation in History Fragment.

I passed SharedPreferences and fetch the string in onResume/onStart method's of second fragment(History fragment) but it only shows the history of last calculation when I closed my application

I am using Custom ArrayList to Store and display my History output in History Fragment.

I want to pass data(calculation to show history) to HistoryFragment whenever anyone clicks "=" button in application. "=" button calls the equal method in calculator app.

Example of what is happening if I do this calculation in my calculator it does not update

and in History it shows that last one from last when I closed application

here's what I have done so far

it is the code of saving answer in CalculatorFragment.java(first fragment) using SharedPreferences

I am also confused about which one to use .appy() or .commit()

I have this huge dataset (100M rows) of consumer transactions that looks as follows:

Considering a function (apply_this_function) that will be applied to a dataframe:

I'm defining a roles guard like this:

I'm getting "Read timed out" when running a query on a 1,3b row db.

It is not a particular advanced query that groups together hashtags in tweets:

There are the two images I am working with:

(Here the images are not the same size, but in my programme they are the same)

After taking the skimage.metrics.structural_similarity() of the two images above, I have the following thresh:

As you can see, it consists of 2 shapes which are almost circles but not quite (the extra part at the bottom right is the circle's shadow)

I want to watershed this thresh so that I obtain two circles, but my current code gives me this:

Instead, I want something that looks like this in blue:
