vice | Go channels at horizontal scale

I have data like this

According to the Idris crash course:

The Idris type checker knows about the Lazy type, and inserts conversions where necessary between Lazy a and a, and vice versa.

For example, b1 && b2 is converted into b1 && Delay b2. What are the specific rules that Idris uses when deciding where to place these implicit conversions?

I'm trying to understand histomorphisms from this blog on recursion schemes. I'm facing a problem when I'm running the example to solve the change making problem as mentioned in the blog.

Change making problem takes the denominations for a currency and tries to find the minimum number of coins required to create a given sum of money. The code below is taken from the blog and should compute the answer.

I have created a remix of the Networked A-frame examples project. I've been testing out some features and for some reason, the toggle video button in the bottom left corner of the screen isn't working on the video example.

The function is triggering however it isn't changing the video from on to off and vice versa. I'm not sure why this is, but I'm wondering how I can make it so when the button is clicked, if video is on, it will turn off and if video is off, it will turn on. How can this be done? The code is found in public/examples/index.html at line 106 of this project:

Code snippet that isn't working:

I have written the following function to help with error handling

I am training 2 autoencoders with 2 separate input paths jointly and I would like to randomly set one of the input paths to zero.

I use tensorflow with keras backend (functional API).

I am computing a joint loss (sum of two losses) for backpropagation.

A -> A' & B ->B'

loss => l2(A,A')+l2(B,B')

networks taking A and B are connected in latent space. I would like to randomly set A or B to zero and compute the loss only on the corresponding path, meaning if input path A is set to zero loss be computed only by using outputs of only path B and vice versa; e.g.:

0 -> A' & B ->B'

loss: l2(B,B')

How do I randomly set input path to zero? How do I write a callback which does this?

I'm trying to write two functions for converting Cartesian coordinates to spherical coordinates and vice-versa. Here are the equations that I've used for the conversions (also could be found on this Wikipedia page):

And

Here is my spherical_to_cartesian function:

I'm trying to implement my own async method builder for a custom awaitable type. My awaitable type is just a struct containing a ValueTask.

The problem is my asynchronous method builder only works when it's a class or compiled in Debug mode, not a struct and in Release mode.

Here's a minimal, reproducible example. You have to copy this code into a new console project on your local PC and run it in Release mode; .NET Fiddle apparently runs snippets in Debug mode. And of course this requires .Net 5+: https://dotnetfiddle.net/S6F9Hd

This code completes successfully when CustomAwaitableAsyncMethodBuilder is a class or it is compiled in Debug mode. But it hangs and fails to complete otherwise:

I have following two dataframes:
