I am trying to upgrade to React Router v6 (react-router-dom 6.0.1).

Here is my updated code:

I am using Jupyter notebook (from anaconda Jupyter lab) on Windows 10 and tried to undo/redo changes in the selected cell. However, I can only undo/redo changes in the whole notebook.

For example, I edited cell#1 then cell#2. Say I want to undo changes in cell#1, so I go to cell#1 and press control+z, it will however undo the change in cell#2.

My friend using Mac doesn't have this issue. Are there any settings for this? I searched online and didn't find anyone who has the same problem. It is so weird!

I was using the Material UI Timepicker but after updating to MUI 5 it is not working anymore. I updated everything to @next and @material-ui/core (version 5.0.0-beta.5) and @material-ui/lab (version: 5.0.0-alpha.44).

I want to use Date picker from MUI but I get this error and I don't know what exactly is wrong. here is my code:

I've built this new ggplot2 geom layer I'm calling geom_triangles (see https://github.com/ctesta01/ggtriangles/) that plots isosceles triangles given aesthetics including x, y, z where z is the height of the triangle and the base of the isosceles triangle has midpoint (x,y) on the graph.

What I want is for the geom_triangles() layer to automatically provide legend components for the height and width of the triangles, but I am not sure how to do that.

I understand based on this reference that I may need to adjust the draw_key argument in the ggproto StatTriangles object, but I'm not sure how I would do that and can't seem to find examples online of how to do it. I've been looking at the source code in ggplot2 for the draw_key functions, but I'm not sure how I would introduce multiple legend components (one for each of height and width) in a single draw_key argument in the StatTriangles ggproto.

Hello I am trying to transfer a custom SPL token with the solana-wallet adapter. However i am having trouble getting the wallet's secret key/signing the transaction.

I've looked at these answers for writing the transfer code but i need to get the Singer and i have trouble figuring out how with solana-wallet adapter. These examples hardcode the secret key and since i'm using a wallet extension this is not possible.

How can you transfer SOL using the web3.js sdk for Solana?

How to transfer custom token by '@solana/web3.js'

according to this issue on the webadapter repo https://github.com/solana-labs/wallet-adapter/issues/120 you need to:

1. Create a @solana/web3.js Transaction object and add instructions to it
2. Sign the transaction with the wallet
3. Send the transaction over a Connection

But i am having difficulty finding examples or documentation as to how to do step 1 and 2.

I have a Python code that is creating HTML Tables and then turning it into a PDF file. This is the output that I am currently getting

This image is taken from PDF File that is being generated as result (and it is zoomed out at 55%)

I want to make this look better. Something similar to this, if I may

This image has 13 columns, I don't want that. I want to keep 5 columns but my major concern is the size of the td in my HTML files. It is too small in width and that is why, the text is also very stacked up in each td. But if you look at the other image, text is much more visible and boxes are much more bigger width wise. Moreover, it doesn't suffer from height problems either (the height of the box is in such a way that it covers the whole of the PDF Page and all the tds don't look like stretched down)

I have tried to play around the height and width of my td in the HTML File, but unfortunately, nothing really seemed to work for me.

Edit: Using the code provided by onkar ruikar, I was able to achieve very good results. However, it created the same problem that I was facing previously. The question was asked here: Horizontally merge and divide cells in an HTML Table for Timetable based on the Data in Python File

I changed up the template.html file of mine and then ran the same code. But I got this result,

As you can see, that there were more than one lectures in the First Slot of Monday, and due to that, it overlapped both the courses. It is not reading the

The modified template.html file has this code,

Please note this question is an extension of this previously asked question: How to make Images/PDF of Timetable using Python

I am working on a program that generates randomized Timetable based on an algorithm. For the Final Output of that program, I require a Timetable to be stored in a PDF File.

There are multiple sections and each section must have its own timetable/schedule. Each Section can have multiple Courses whose lectures will be allocated on different slots from Monday to Friday by the algorithm. For my timetable,

• There are 5 days in total (Monday to Friday)
• Each day will have 5 slots (0 to 4 in indexes. With a "Lunch" Break between 3rd and 4th slot)

As an Example, I have created below a dictionary where key represents the Section and the items have a 2D Array of size 5x5. Each Index of that 2D array contains the course details for which the lecture will take place in that slot.

I'm trying to pivot to a longer format using dplyr::pivot_longer, but can't seem to get it to do what I want. I can manage with reshape::melt, but I'd also like to be able to achieve the same using pivot_longer.

The data I'm trying to reformat is a correlation matrix of the mtcars-dataset:
