Strategy for storing whether a user has viewed an announcement or not

2021.09.17 00:21 pmceldowney Strategy for storing whether a user has viewed an announcement or not

Im currently working on a new announcement feature for an app and am curious on the strategies people would use.
Announcements can be created by our admins and can be of type minor or major. There can only be one major at a time and multiple minor.
These announcements will show up along with in-app notifications and can be dismissed. I’ve created a schema for announcements and am struggling to figure out to store whether a specific user has viewed that announcement or not.
I immediately thought to use localStorage to store viewed announcement id’s, but there could potentially be a large amount of announcements at once and we also wouldn’t want users seeing the same announcement when they go to their other devices.
So then I thought to store the viewed announcement id’s on the User schema, but if I go that route I’d have to decide when and how to trim the length of that array so it doesn’t continue to grow with each viewed announcement.
I’ve also considered the option of limiting how many announcements can exist at once so our admins have to delete old ones before they create a new one.
I’ve been picking at this all day and am sure once I take a break something will spark in my mind, but I’m curious how other people would handle this.

2021.09.17 00:20 chucklefishh Dead fish crawling with creatures under the microscope.

I managed to get some fresh (ocean) fish last Monday with the purpose of dissecting it on Wednesday with the children I teach. The fish was left in my fridge (with guts and all) from Monday to Wednesday. After dissecting the fish we decided to look at the scales through a microscope, and it was literally CRAWLING with creatures. Could this be parasites?. I thinking since the fish was in my fridge uncleaned for a couple of days before dissection. I don't think it was lice as you would see that without a microscope.

Hi guys! I'm looking for advice on where to buy a house. I'm looking for town near NYC, with access to public transportation, low taxes, large space, good schools and the complete absence of crime. I should also add I will not consider any place that has a sizeable presence of immigrants or minorities. Looking to spend $150K. Thanks so much!

2021.09.17 00:20 bread-witch Can I reuse an old essay for my common app?

I want to write about the same topic I won an essay contest for back in August, and while the essay is my own intellectual property it is posted online. Would it be bad to tweak that essay for my common app or should I write a completely different one? I’m just worried that it might pop up on plagiarism detectors.
And if anyone is wondering the topic was about how I first learned the cultural significance of my stilt walking when I performed at a Caribbean senior citizen home.
Thank you for any advice!

2021.09.17 00:20 lagrange12341 How do you take notes?

Hello everyone
I started last year studying mathematics at a top 10 university. Sadly i failed my exams (at least not completely) and as a result i will retake the year.
One thing i always struggeled with was taking notes during lecture / from a book. Before university (i’m not american) i always took notes, summarized text etc. and had good success with it. But i feel like that this is not working anymore. Im struggling with the feeling that i need to take notes but then i almost cannot keep up with my professor. If i dont take as much notes and listen to my professor i feel bad because i didn‘t „work much“. Concerning the book - it felt like i cannot summarize it much more as it‘s already very dense written.
I know the best way to learn is doing tons of exercises and i will keep doing that. But i really need to find a way to take good and helpful notes.
We do have a script that the cours follows but its 1000+ pages for a semester. There are no slides but our professors do share their handwritten notes during lecture.
It would really help me if you could share how you take notes and how. I really wan‘t to succeed this year. Thank you
