barracuda | Ruby wrapper library for the OpenCL architecture

I have a list of filepaths in the first column of a dataframe. My goal is to create a second column that represents file categories, with categories reflecting the words in the filepath.

I have a string separated by commas ,. I want to find the longest string from the given string.

My data is comprised of a column of fish counts with the corresponding when and where of each catch.

My original question can be seen here (Automating a ggplot for each level in a group), but I thought I'd ask it differently to leave it open for many different ways to answer this question rather than a "how to" question to fix my poor attempt.

I'd like to make the process of creating a time series plot like the one below quicker/automatic (i.e., doesn't require the user to enter one species name at a time). Perhaps with an "if" loop. Something that tells R to cycle through all the unique common names in the data and print (or save to png) a plot using the code below (with the "common_name" of each species as the title of their respective plot). If there isn't enough data for a plot, R should print a message: "Not enough data for a plot", or something.

Here is a sample of my data (as you can see, there are over 100 species to make a plot of). This data sample shows only 3 species, 5 sites out of 47, and 3 years out of 16 years worth of data.

The web application I'm developing is a typical web app done with Angular as front-end technology and Java spring boot as backend.

As you can see in the above picture, I create another directory in the root folder named filebeat-7.12-darwin-x86_64 that contains some js files.

When I try to run the javascript test with command npm run webapp:test, I receveid a lot of errors. I notice that as default configuration the *.js, *.ts files that lint try to analyze were look for in filebeat-7.12-darwin-x86_64 folder too.

There is a way to specify for the command npm run webapp:test from which folder it has to start to test? I report just some lines of the log the command I mentioned produced.

I recently moved my old server to EC2 and cannot run mysql in the new EC2 instance. I ran sudo service mysql start and get start: Job failed to start as return. Here is the error log

I have 3 nodes Galera cluster with MariaDB 10.4.13. Each node have 32GB RAM, and 2GB Swap. After my mysql tuning about 1 month ago each node memory almost full, but I think it is ok. But the last few days Swap size reached maximum and does not go down. My my.cnf looks like this:

With this configuration, I wanted MariaDB to use maximum, as long as it is not critical. I wanted to review this configuration, and maybe disable query_cache part, and also adjust InnoDB values. Please give me some recommendations, and also let me know if the swap size is good enough, or maybe need to disable mysql to use swap at all.

I have a column named "Trip", in which I have infos such as the hotel, country, and type of trip. The thing is these infos are hand typed, so sometimes instead of typing "HOTEL ABC", the person entering the infos simply enters "ABC", or event "HTL ABC". Also, ABC can also refer to a country.

What I want is to extract all hotel names on each cell. Here's the function I created, but I can't get it to work. (Y2 is the TRIP Column)
