straight | The Straight Framework for PHP | JSON Processing library

I read this answer, which clarified a lot of things, but I'm still confused about how I should go about designing my primary key.

First off I want to clarify the idea of WCUs. I get that WCU is the write capacity of max 1kb per second. Does it mean that if writing a piece of data takes 0.25 seconds, I would need 4 of those to be billed 1 WCU? Or each time I write something it consumes 1 WCU, but I could also write X times within 1 second and still be billed 1 WCU?

Usage

I want to create a table that stores the form data for a set of gyms (95% will be waivers, the rest will be incidents reports). Most of the time, each forms will be accessed directly via its unique ID. I also want to query the forms by date, form, userId, etc..

We can assume an average of 50k forms per gym

Options

• First option is straight forward: having the formId be the partition key. What I don't like about this option is that scan operations will always filter out 90% of the data (i.e. the forms from other gyms), which isn't good for RCUs.

• Second option is that I would make the gymId the partition key, and add a sort key for the date, formId, userId. To implement this option I would need to know more about the implications of having 50k records on one partition key.

• Third option is to have one table per gyms and have the formId as partition key. This seems to be like the best option for now, but I don't really like the idea of having a a large number of tables doing the same thing in my account.

Is there another option? Which one of the three is better?

Edit: I'm assuming another option would be SimpleDB?

I have an attendance record with a date column (weekly) and an attendance column for that week.

I just want a bar chart or line graph to show the change over time.

I have a for loop doing something I would have thought relatively straight forward on Python 3

I am successfully using the Tapkey token exchange endpoint to exchange a Firebase token for a Tapkey one, but am then having an error calling login.

I am requested the following Scope's when exchanging the token:

register:mobiles read:user read:ip:users handle:keys

My swift code is below (basically lifted straight from the documentation):

How do I align the Color views in a straight line with the text to the side?

To look like so (text aligned leading):

█  red
█  green
█  blue

Or this (text aligned center):

█    red
█  green
█   blue

Current code:

I'm getting following error on some devices while opening url. I don't get any error on my devices but many devices are.

I will go straight to the point.

I have a variable called showForm const [showForm, setShowForm] =useState(false); I am controlling if I should show a form or not with it .

The form will also be shown after 20s using setTimeout and I initialise a timeoutId (let timeoutId;) variable on global scope to keep track of the setTimeout.

I have a useEffect hook with an if statement that checks the value of showForm

I'm trying to make an animation which will:

1. Show some points on plotting area
2. Connect some of these points by straight lines one by one The picture below shows the steps

How can I do it in matplotlib? I have tried smth with:

I have a situation with a Java Socket Input reader. I am trying to develop an URCAP for Universal Robots and for this I need to use JAVA.

The situation is as follow: I connect to the Dashboard server through a socket on IP 127.0.0.1, and port 29999. After that the server send me a message "Connected: Universal Robots Dashboard Server". The next step I send the command "play". Here starts the problem. If I leave it like this everything works. If I want to read the reply from the server which is "Starting program" then everything is blocked.

I have tried the following:

-read straight from the input stream-no solution

-read from an buffered reader- no solution

-read into an byte array with an while loop-no solution

I have tried all of the solution presented here and again no solution for my case. I have tried even copying some code from the Socket Test application and again no solution. This is strange because as mentioned the Socket Test app is working with no issues.

Below is the link from the URCAP documentation:

https://www.universal-robots.com/articles/ur/dashboard-server-cb-series-port-29999/

I do not see any reason to post all the trials code because I have tried everything. Below is the last variant of code maybe someone has an idea where I try to read from 2 different buffered readers. The numbers 1,2,3 are there just so I can see in the terminal where the code blocks.

In conclusion the question is: How I can read from a JAVA socket 2 times? Thank you in advance!
