arity | Java Arithmetics Engine

I’m using Mac OS Big Sur with Xcode 13.2.1. I would like to run rdebug-ide in my Rails 6 (Ruby 3.0.2) app but not quite sure what version of debase I need, which is a requirement to install rdebug-ide as I understand it. When I try to install the debase gem, I get the errors …

Consider the following article from the JLS (§15.13.1)

A method reference expression ending with Identifier is exact if it satisfies all of the following:

• If the method reference expression has the form ReferenceType ::[TypeArguments] Identifier, then ReferenceType does not denote a raw type.
• The type to search has exactly one member method with the name Identifier that is accessible to the class or interface in which the method reference expression appears.
• This method is not variable arity (§8.4.1).
• If this method is generic (§8.4.4), then the method reference expression provides TypeArguments.

Consider the following code snippet:

I've recently started learning Zig. As a little project I wanted to implement a small QuickCheck [1] style helper library for writing randomized tests.

However, I can't figure out how to write a generic way to call a function with an arbitrary number of arguments.

Here's a simplified version that can test functions with two arguments:

Say that I have a Data.Tree holding characters: Tree Char:

My PicoCLI-based application has multiple commands and sub-commands with general options that apply to all commands, and some options which apply to the specific command. The general options are used for all the commands.

My PicoCLI (sub-)commands are similar to this example:

I already referred the posts here, here and here. Don't mark it as duplicate.

I am working on a binary classification problem where my dataset has categorical and numerical columns.

However, some of the categorical columns has a mix of numeric and string values. Nontheless, they only indicate the category name.

For instance, I have a column called biz_category which has values like A,B,C,4,5 etc.

I guess the below error is thrown due to values like 4 and 5.

Therefore, I tried the belowm to convert them into category datatype. (but still it doesn't work)

I am trying to iterate a list and filter out all the elements that match a particular criteria. So far, I use the map function and, at every iteration, I will check whether that element should be filtered or not.

I can easily use tf.map_fn when the function has one output:
