Chlorine | easiest way to interact with OpenCL compatible devices | GPU library

Hello I have had some trouble with my projecting I'm trying to make someting where you can search a value and it returns an the row that value was in. I've only been able to do it with the atomic number because they're ordered. I was planning to use classes but I don't think I'll actually need it (that's what import element is for)

Here's my code:

For background: I was recently hired as a database engineer for a water treatment company. We deploy water treatment machines to sites across the country, and the machines treat water and send continuous data back to us regarding the state of incoming water (flow rate, temperature, concentration of X in incoming water, etc.), and regarding the treatments the machine applied to that water at that point in time. Over time, sites (and their various components) change a lot: a machine might break down and need to be replaced, a different concentration of chemical may be used to fill the machine's tanks, its flow meters and other sensors might be recalibrated or set to scale differently, its chemical pumps might be replaced, and on and on. These affect the interpretation of the data: for example, if 5 mL of chlorine was added to the incoming water at 01/01/2021 12:00:05, that means two completely different things if the chlorine was 5% concentrated or 40% concentrated.

Water treatment datapoints are identified by a composite key consisting of the ID of the site, and a timestamp. It would be easy if the only data that mattered was current data, as I could just store the configuration settings on a Site level and pull them up for datapoints as needed. But we need to be able to correctly interpret older data. So, I thought about storing configurations in another table, trackingall the settings for each site over each time period, but it's not possible to create a foreign key between the continuous timestamps of the datapoints and the start/end dates of the configurations - the closest thing would be some kind of range check, like "Datapoint.TimeStamp BETWEEN Configuration.Start AND Configuration.End". So the only other option I see is to store every configuration setting for every datapoint alongside each datapoint, but that seems like a terrible solution given how many configuration settings there are and how many datapoints are generated, especially since most of the settings don't even change often.

So, is there a way to store historical configurations for each row of data in a way that is at all normalized, or is the only possible solution to cram all the settings into each datapoint?

I'm experimenting in Clojure with running independent threads and I'm getting different behaviors I don't understand.

For my code editor I'm using Atom (not emacs), REPL is Chlorine.

I'm testing a really simple function that just prints numbers. This one prints from 100 to 1 and takes no inputs:

I have an Angular Material table in which I am populating data. I have an input box as one of the columns in the table to accept a value from the user. The table looks like this -

Since the records can be more so I am using mat-paginator for pagination as well. The problem I am facing is this - When I enter a value in the text box(like 12 or 10 in the above screenshot) and then change the page and come back to the initial page, the already entered values are lost from all the text boxes(#screenshot 2 & 3).

How can I persist the already entered values in the text boxes even after the page is changed?

Can someone tell me in beginner friendly way why am I not being able to print the Molecule name (here in this case 'NaCl') ? if I replace return Molecule([self, other]) with return Molecule([self.label, other.label]) my code works and produces the expected output but I want to pass instances and not attributes. here is my code:

I have the following text in column A:

I'm trying to do this exercise:

A sodium chloride crystal has sodium and chlorine atoms arranged on a cubic lattice but the atoms alternate between sodium and chlorine, so that each sodium is surrounded by six chlorines and each chlorine is surrounded by six sodiums. Create a visualization of the sodium chloride lattice using two different colors to represent the two types of atoms.

My code is:

I have two angular tables and I am comparing their data side by side, let's say I have default 10 rows to show up on both tables, It can be the case that either if the two tables has less than 10 rows. E.g One table has 10 rows and second has just 1, so the second table end at just 1 row, what I would like to do is to have some empty rows(Number of rows that should be present - number of rows actually present). How can I do that ?

I'm looking for a way the body to animate scrolling right like a news ticker. The only way for me to scroll is to have the body with overflow-x:auto and overflow-y:auto. The width of the body is set so high that it's basically an infinity width.jq

This is what I've done so far:
