I'm using leaflet to present a map of a city and geojson to overlay neighborhoods in the city. I've styled the neighborhoods in my css file. What I want to do is determine the names of the neighborhoods and and certain ones to a different color, but I'm not sure how to do that. Can anyone help?

My geojson file is very long, but it starts out:

I am trying to work through the example from Chapter 5 of the Leaflet.js succinctly book - but cannot get any of the coffee shops to show on my map.

Some of the commands give me errors so I've looked for workarounds, and I suspect the problem could be as simple as files not being in the correct place. Is there an idiot's guide to using databases with leaflet I could follow? Or can someone see the error I am making?

My set up:

• using XAMPP on a Mac - the MySQL Database and Apache Web Server are running
• I created the leafletDB database using the terminal /Applications/xampp/xamppfiles/bin/mysql -u root -p create database leafletDB
• I filled the database by copy paste into the terminal the contents of the CoffeeShops.sql file (I could not get the from CSV command mysql –uroot –pleaflet < "C:\CoffeeShops.sql"; to work, even changing the path to CoffeeShops.sql)
• Checking the database using USE leafletDB; SHOW TABLES; and SELECT COUNT(*) FROM coffeeshops; all gave the expected results.
• The leaflet database is located in /Applications/XAMPP/xamppfiles/var/mysql/
• I copied the coffee.php file to the /Applications/XAMPP/xamppfiles/htdocs/CoffeeExample folder, which is the same file as the listing43.html file (the file that creates the map)
• The only change I made to the listing43.html file was the path to the mugIcon (put in the same folder). I also tried simply removing the icon command - it made no difference.

The map displays, any markers coded directly into the html file display - but nothing from the database.

What have I got wrong?

As requested here is a copy of all the code - sorry for how long this is

I have a list called transactions_clean, cleaned up from whitespace etc., look like this:

I have a dataframe that looks like this

Im trying to parse the the following json and map it to equivalent objects:

I'm learning Rust from the Book and I was tackling the exercises at the end of chapter 8, but I'm hitting a wall with the one about converting words into Pig Latin. I wanted to see specifically if I could pass a &mut String to a function that takes a &mut str (to also accept slices) and modify the referenced string inside it so the changes are reflected back outside without the need of a return, like in C with a char **.

I'm not quite sure if I'm just messing up the syntax or if it's more complicated than it sounds due to Rust's strict rules, which I have yet to fully grasp. For the lifetime errors inside to_pig_latin() I remember reading something that explained how to properly handle the situation but right now I can't find it, so if you could also point it out for me it would be very appreciated.

Also what do you think of the way I handled the chars and indexing inside strings?

I'm new to bipartite network analysis and i've some trouble with basic measures. I'm trying to work on bipartite networks without projecting in 1-mode graphs. My problems come from the fact that the igraph package allows to create bipartite graphs but that the measures do not seem to adapt to the specificity of these graphs.

So, my general question is how do you do when you work directly on bipartite networks ?

Here a concrete exemple with density
