rye | Safe , parallel access to Unix shells from Ruby

The reason of the issue is not that r and/or s start with a byte >= 0x80, but that the message messNOT is UTF-8 encoded during verification.

The verification for the problematic message messNOT is successful if messNOT is not UTF-8 encoded but hex decoded. In contrast, for the working message messYES, verification is successful if messYES is UTF-8 encoded.

Since both messages are UTF-8 encoded in the posted code, this explains why the verification of messNOT fails while that of messYES succeeds.

In order for verification to succeed for both messages, the simplest way is to pass the message as byte[] in verifySignature():

First, your button needs to call a function - not console.log - for example:

Click me!

Then you need that function. There are many ways to do this, but an easy way would be to set your books as an array and then use the function to pick a random element from the array and use innerHTML to display it.

The element on the page to show the picked book:

The book array:

I was able to make it work. Here is the updated code. Right after pd.concat, the following code helped:

To solve your specific issue, you can generate dummy variables to run your desired clustering.

One way to do it is using the dummy_columns() function from the fastDummies package.

As @dcarlson recommended, you can run mice on the entire dataframe, then you can use complete to get the whole output dataframe. Then, you can join the new data with your original dataframe.

Here's a solution with higher-order functions, working in the whole data-manipulation paradigm:

Here is a starting point how you could achieve your task:

You just need to make data into a DataFrame first:

1. Use your dict1 to make a new DataFrame with the same index & columns as df:
