I have a table like this:

I think this is a simple task, but I'm a biologist who only knows a teeny bit of code and after several days of trying to figure this out, I'm at my wit's end :'(

Using terminal on a mac. I have a CSV file that I want to split into separate files by row (162 rows) and I want to name the file by the content of the first and second column (genus_species). Then I need all 162 genus_species to be saved as HTML files.

I have only attempted the "splitting" part with Ruby (recommendation from StackExchange/overflow). Below are some of my attempts. They are frankensteins of helpful-ish forums, and after each I made a little comment on why it did not work.

Example HTML

For a learning excercise, I'm building a car builder page and want to select car color, then wheel style, with the picture of the car changing to reflect each unique color/wheel combination. There are 16 colors and 5 wheel styles, and I have a picture that represents each unique value.

I was able to work out the first steps to select the car color and the wheel option separately of each other. For example if I click the red car color, I want the color to stay while I cycle through the wheel options. Currently, it defaults back to black, then cycles through the wheels for the black color only.

I'm failing to understand the general logic that should be used to approach a simple two-option combination like this, and things I try like capturing the selected option with a variable to carry it over to the wheel selection breaks the functionality. Can anyone point me in the proper general direction?

Here is the page in its current state - https://www.sanjosecoder.com/porsche/index.html

I know why the code isn't working - but I don't know how to start laying out to factor the two selections together.

Any guidance would be greatly appreaciated!

I have a short, ~2-second video that plays on a loop in the background of a website I'm making, which, when it appears through transparent portions of divs, gives the effect of a metallic shimmer. It looks great. The problem is, when an iOS device is in low power mode, the video not only doesn't play (which is acceptable, I get it), it shows a big honkin' play button that shows through those same transparent portions of divs. I need to get rid of that, but every solution I've found seems to not work in iOS 14.

Here's the video tag:

I'm extracting table from HTML. but I can't write it properly to csv file. Before that I use argparser but I had to change because I want to make a loop for a lot of files. My code is like this:

I have a rather particular question about color gradients in Povray. There are two polygons in 3D space and I want to have an even color gradient from green to red. I managed to determine the direction and the scale of the gradient to match the direction of the polygons. I can decide, how many color cycles I want to have on each polygon. Nevertheless the scaling is different on the polygons. The yellow strip is much larger in one than in the other. I have no idea, what I can do against it. Any help is highly appreciated.

Here is the code, that generates the images:

This is the code I would like to work with:

I have a music app that has a job to find music recommendations based on a tag id.

There are two entities involved:

• Song - a song record contains its name and a list of music tag ids (genres) this song belongs to
• MusicTag - the music tag itself, includes id, name etc.

Data is currently stored in MongoDB.

The Songs collections in mongo have millions of songs, and each song has an average of 7 tag ids. The MusicTags has about 30K records.

The Songs collection looks like that:
