aquarium | Splash HAProxy Docker Compose | Continuous Deployment library

I was following a tutorial for learning kotlin and ran into this example.

I'm trying to learn the difference between Hashtable and HashMap and I'm trying to add specific prices to these items here. The goal is to print the price of the item selected from comboItem into txtPrice.

I am unsure about what to do in the following situation, where some levels of the fixed effect are missing (within a random effect) - they are unbalanced.

Imagine an aquarium with 5,000 individual fish. They are part of 100 different species. I want to test if there is a relationship between their weight (continuous) and whether they are fed by Alan or Susie (there only are two employees that feed fish). Species is the random effect.

My model looks like this: weight ~ employee + (1 + employee | species): mixed model (lmer) with random intercept and slope.

But for some species, all fish are fed by the same employee (Alan or Susie). Should I leave these observations in the model, or should I exclude them? Is there some literature on this?

I have a data frame with three columns (Category, Sub.category and Acitivty). I need a nested list, with these three levels to put into shinyTree.

I'm trying to match the format of this .Rds file to create a shinyTree.

My full table is 99 lines, I've included 30 below, but may need to do over 100+ in the same way.

So far I've got

I was given the task to create an NYC Guide project out of Python and Django. I am iterating through a nested dictionary to render boroughs, activities, and venues. The home page lists a handful of boroughs. The boroughs page lists a handful of activities in each borough. The activities page lists a handful of venues to select. My issue is when I click on one of the activities I receive a TracebackError. I am trying to at least render the venues page that has a simple 'VENUES PAGE' on it. I'd love any advice or feedback. This is my first Django project so forgive me if I didn't explain this thoroughly enough. Feel free to ask for further explanation! What I am ultimately trying to do is render an unordered list of venues for each activity in the activities page. I would like each li to be a url that takes me to the venue.html page. It doesn't have to render a specific venue. I can take it from there. I am stuck on this one step. I have already successfully rendered the borough and activities pages, and I have been able to loop through the activities, but when I click on a specific activity I get this error:

"TypeError at /brooklyn/beaches activity() missing 1 required positional argument: 'venues'"

In my current IOT project. I will be using multiple ESP8266s (3) to send data and receive actions. Each MCU will be in charge of monitoring different aquariums around the house. I have thought of structuring my topics like the following:

"Data" topics will follow the same structure, for example to retrieve temperature data:

Here's what I want to do:

I'm quite new at coding and trying to teach myself via books and other available sources, so please bare with me.

Does anyone have an idea how to make my close buttons work for all modal pages using querySelector or QuerySelectorAll? Currently, I'm trying to create a site that shows my artwork. Each piece of work would open up a modal page when you click on it, further describing each piece. For some reason, my close button only seems to work for the first page when I use QuerySelector, but when I change it to querySelectorAll, the close button does not work properly on any of the pages. I would think I need to use querySelectorAll, being that the close button will be on each modal page, and I'm trying to capture all .closeButton classes in one shot.

I'm using Node Red to monitor a set of aquaria. We have 14x DS18b20 sensors, one for each aquarium. I'm able to send an alarm via email if the measured temperature of one sensor is different to the set value. However, sometimes, during maintenance, we take the sensors out of the aquaria. Therefore, I'd like to write a fucntion that only sets the alarm if the abnormal value was mesured e.g. three consecutive times (values are measured every 15 min). How could I do that?
Currently, I wrote a function that sets msg.payload to "Alarm" if any msg.payload[i].temp (the 14 measured values in an array) is more than 1.5 °C diffrent to the set value. This fucntion is followed by a switch that then triggers an email.
Do you have suggestions for my problem? Thanks for your help!
