Elucidate | Elucidate : A GUI to drive the SnapRAID command line

I'm currently reading Hands-On Programming With R and the author first suggests this code to deal cards from the top of a deck:

I want to extract all confirmed transactions from the bitcoin blockchain. I know there are repos out there (e.g. https://github.com/znort987/blockparser) but I want to write something myself for my better understanding.

I am have tried the following code after having downloaded far more than 42 blocks and while running bitcoind (minimal example):

I'm trying to create a public and private key for Snowflakes RSA authentication. I;ve been following this documentation. However, I need for there to be a passphrase and the example provided does not elucidate such a feature.

This is what I've tried, but it does not work:

I have this function which is defined by 3 variables xvalue, P, C

Trying to understand callPackage, so looked up its implementation where it uses lib.functionArgs (source), but there is already a builtins.functionArgs primop, an alias of __functionArgs (implemented in C).

lib.functionArgs is defined as

I am trying to print a table of integer squares. The aim is to write a program that pauses after every 24 squares and asks the user to print Enter to continue. This is not too complex, I have "completed" the task at hand in C.

My concern: a seemingly insignificant (but observable) minor issue occurs when I compile & run the following code:

I have a df that looks like:

I have two sheets: Sheet2 and Sheet3. The goal was to highlight the cells in column A of sheet3 that has a match in column A of sheet2. Here's sheet2: enter image description here. Here's for sheet3: enter image description here

Now I used this formula to determine if there's a match: =SUM(--(A2=Sheet2!$A$2:$A$4))>0

Now here's the vba code that I used to implement the conditional formatting:

I am using a motion tracking device equipped with a gyrometer/accelerometer/magnetometer. The device outputs its rotational orientation at any timepoint as a quaternion.

As I rotate the device from its original orientation, I am trying to calculate two things: (1) the distance along the surface of the sphere from its original orientation (I've actually already completed this step), and (2) the direction of the orientation - but the direction needs to be a simple 1 or -1, not a vector.

Let me explain further what I mean with regard to the direction: Let's assume the device begins in an initial rotation state, and then I rotate it in one direction. After completing some amount of rotation, I then rotate it back to its original position, and then I continue rotating it along that same trajectory - essentially rotating it in the opposite direction of my original rotation.

So, if I have an original quaternion Q0, and then I have another quaternion representing my first rotation Q1, I would then like to say for any future quaternion Qn:

1. What is the distance of Qn from Q0?
2. What is the direction (valid values are 1 or -1) of Qn from Q0? Where "1" is "in the same direction as the rotation from Q0 to Q1" and "-1" is "in the opposite direction as the rotation from Q0 to Q1".

Like I said, the "distance" part I have already solved thanks to finding this helpful post: https://math.stackexchange.com/questions/90081/quaternion-distance?newreg=f0fcab1eca8d4a4faaad1ea555d1cdf7

I haven't solved the direction part yet. The following posts have gotten me part of the way there:

1. Difference between the two quaternions
2. 'Difference' between two quaternions

But my understanding is still incomplete. Can anyone help elucidate how I could do this? Thanks!
