Why question mark appears on Github instead of the actual link?

My README file is like this:

I was reading this Monadic Parsing article while I was trying to implement a pretty simple string parser in Haskell and also get a better understanding of using monads. Down below you can see my code, implementing functions for matching a single character or a whole string. It works as expected, but I observed two strange behaviors that I can't explain.

1. I have to handle single characters in string, otherwise, the parser will return only empty lists. To be exact, if I remove this line string [c] = do char c; return [c] it won't work anymore. I was expecting that string (c:s) would handle string (c:[]) properly. What could be the cause here?

2. In my opinion, string definition should be equivalent to string s = mapM char s as it would create a list of [Parser Char] for each character in s and collect the results as Parser [Char]. If I use the definition based on mapM, the program would get stuck in an infinite loop and won't print anything. Is something about lazy evalutation that I miss here?

.

I use R for most of my data analysis. Until now I used to export the results as a CSV and visualized them using Macs Numbers.

The reason: The Graphs are embeded in documents and there is a rather large border on the right side reserved for annotations (tufte handout style). Between the acutal text and the annotations column there is white space. The plot of the graphs needs to fit the width of text while the legend should be placed in the annotation column.

I would prefer to also create the plots within R for a better workflow and higher efficiency. Is it possible to create such a layout using plotting with R?

Here is an example of what I would like to achieve:

And here is some R Code as a starter:

I am using Ubuntu 20.04.2 LTS via VMWare on macOS BigSur. I have the latest versions of tcl, tcl-dev, tk and tk-dev installed - version 8.6. I want to compile the source code for the Architecture lab project. The source code is from 2016 and located in the self-study handout. Compilation fails [with error messages detailed below], possibly due to the source code relying of tcl8.5 instead of the latest version. Would installing versions 8.5 of these packages solve the problem?

To make the GUIs work, in the project Makefile I need to assign one variable [which I have done] and update two more so that gcc can find the relevant libraries [libtcl.so and libtk.so] and header files [tcl.h and tk.h].

Attempt

After reading a large json file and capturing only the 'text' column, I would like to add a column to dataframe and set all rows to a specific value:

I'm writing my first makefile to compile latex code several ways (using the beamer package), but am stuck at a very basic problem that has nothing even to do with latex. Consider the following MWE of my makefile:

I'm working on Stanford CS107 assignment 3, in which we implement a C version "vector". In the end I have some files in my directory,

I do not understand what is happening.

I made a program to get a char input and output it back. I receive this exception every time I press enter to input a value into the program:

Unhandled exception thrown: read access violation. this->_format_it was 0x38.

I have tried a large arrangement of inputs and it seems that no matter what I input it will throw this at me. In fact, This is almost exactly the code my college gave me

Here is the code:

I've been playing with the example from this presentation (slide 41).

It performs alpha blending as far as I'm concerned.
