bender | Bender - Serverless ETL Framework | Data Migration library

I am programming a stepper motor device for an Arduino device. In my header file I declared instances of the AccelStepper library. Later I want to iterate over the steppers using an array of pointers. I found that the instances have different addresses. Could you explain whats wrong here and give me a hint how I can fix this?

I'm trying to setup a simple while loop, but I keep getting this error:

'While' is a reserved keyword.

Robot Framework 4.1.3 (Python 3.8.10 on linux)

For sanity, I stripped everything out and created the following test with examples straight from the robotcorp docs (https://robocorp.com/docs/languages-and-frameworks/robot-framework/while-loops)

I have an index method in a controller that returns a collection(https://laravel.com/docs/8.x/collections) to a view

I have the following code which exports an object to an XML file, then reads it back in and prints it on the Information stream.

Basically I have a table like this:

My job is to retrieve all relevant movies based on a substring of the movie name. For example, if a user enters a substring such as "av" (e.g., they enter "http://localhost:5000/search/movies?name=av"), they will find movies like The Avengers and Avatar.

Because the assignment requires the use of a Model-View-Controller(MVC) design with a pool of open connections, I have created 3 separate python files (a model, a controller and a database). For full information, this is my database file (shown below):

Background

I need to parse CSV files, and cl-csv et. al. are too slow on large files, and have a dependency on cl-unicode, which my preferred lisp implementation does not support. So, I am improving cl-simple-table, one that Sabra-on-the-hill benchmarked as the fastest csv reader in a review.

At the moment, simple-table's line parser is rather fragile, and it breaks if the separator character appears within a quoted string. I'm trying to replace the line parser with cl-ppcre.

Attempts

Using the Regex Coach, I've found a regex that works in almost all cases:

("[^"]+"|[^,]+)(?:,\s*)?

The challenge is getting this Perl regex string into something I can use in cl-ppcre to split the line. I have tried passing the regex string, with various escapes for the ":

right now I want to get myself more familiar within the filed of linear programming using julia/JuMP. More specifically, I'm trying to implement the algorithm for benders decomposition. Since I'm stuck at certain parts, I wanted to look into other implementations which did similar before. Fortunately, I could find one in the official tutorial section of JuMP: https://jump.dev/JuMP.jl/stable/tutorials/Optimization%20concepts/benders_decomposition/

Unfortunately I can not execute it. It crashes within the first iteration:

I'm trying to add a calculated column based on values of the same and another column calculated from the values in a third column. There are three columns, year, id, and value. If the id for 2011 matches the id for 2005, then subtract the value of 2005 from the value of 2011. So the difference shows 10-11=-1, 20-5=15, and 30-16=14... and the remaining rows can be 0 or NA, it doesn't matter. The following table shows the resulting table with the new difference column.

I know I could split the data into two tables and then create the column via a simple subtraction if the two tables are ordered the same by year and id, but that's not an option for this particular problem. Tried thinking of how I could use case_when or ifelse but it's a mind-bender and can't get my head around it. There are examples I've found but they don't address this - they're mostly based on using a comparison between only two columns, or perhaps three... here, though, one of the values is from the same column. How can I address this?

Your help is appreciated greatly in advance.

Here is the code for the original table:

In Julia, I have a project where I have many calculations. Next is a tiny extract of what it could look like:
