I make a quiz app with MIT app inventor 2 and didn't know how to change the block code so the answer list not displaying random answer in the application.
This is my List, there is 3 List, 1. List of Questions, 2. List of Answers and 3. List of Button_Component:
The procedure that I have for each questions, so it display the quiz app, but still random:
I had changed the block of random integer and replace it with get value in length of list, but my answer list not display in button_component. I got stuck in this, and hope you know the solution. Really appreciate. Thank you.

Here is an example of the data I am using:
"Q7: How does gender income inequality manifest in the communities in which you live and/or work? What do you believe is needed to help close the wealth gap between men and women as well as among women of different races in the county?
Wouldn’t go into pay equity because that would get dismissed. The wealth gap is a more compelling argument.
Equity is more emotional. And wealth gap is more numbers. It goes toward the same thing though."
I am running Rstudio and using library(RQDA) and library(tidyverse).
I am trying to analyze several qualitative interviews formatted in question/answer form as in the provided example. I finished the coding process and now I'm trying to find themes. While coding, I created code categories that correspond with each interview question with the hopes that I would be able to pull out all the codings per code category now. Unfortunately, I cannot figure out how to do it and would appreciate some assistance!
thanks
I am not sure about this but I understood code categories to be helpful for structuring your work by your theoretical perspective. If you create a code category for each interview question (i.e., the topic of the question is your theme/code category), you may have various codes belonging to one "code category", which might not have that much in common. Alternatively, you could create cases (case 1 might be the answers to the first interview question, etc.): "b) Open a file, select part of the file, select a case name, then click button "Link" in "Cases" tab, you can thus link the selected part of file to the selected case" (http://rqda.r-forge.r-project.org/documentation_2.html).
Struggling to find rank values from highest to lowest, please see attached example of what I'm trying to achieve.
My current custom expression is:
Sum([ViolationAmt])
I have tried this:
Sum([ViolationAmt]) over Rank([ViolationAmt])
I've played around with the rank expressions however unable to implement...would be very grateful for some help.
Spotfire Rank Example
I need to make a lot of assumptions here because I don't know anything about your data set or really what your end goal is, so please comment back and/or provide more info in your question if I am off base.
the first assumption is that each row in your dataset represents one, for simplicity, [AccountID] with a [ViolationAmt]. I'm also guessing you want to show the top N accounts with the highest violations in a table, since that's what you've shown here.
so it sounds like you are going to need two calculated columns: one for getting the total [ViolationAmt] per account, and then another to rank them.
for the first, create a column called [TotalViolationAmt] or somesuch and use:
Sum([ViolationAmt]) OVER ([AccountID])
for the second:
Rank([TotalViolationAmt])
it will be useful to read the documentation on ranking functions if you haven't already.
you could probably combine these two into a single column with something like:
Rank(Sum([ViolationAmt]) OVER ([AccountID]))
but I haven't tested this at all. again, if you put in a bit more detail about what you're trying to accomplish it will help you get a better, more detailed answer :)
For a school project I am attempting to write what is described as an "interactive diagnosis environment" using prolog. The user will enter a symptom, and a list of diseases that match the symptom will be printed to the screen. The user will then list another symptom, and diseases will be removed from the previous list if they do not match the second symptom, forming a new list. The new list is then printed.
example user input:
SYMPTOM_IN(fever, 150).
SYMPTOM_IN(vomiting, 1).
A list of possible diseases is printed after each input.
This process is repeated until a diagnosis is made or until it is somehow determined that it can't, at which point tests will be suggested and the user can input data regarding the tests in a similar manner, ultimately arriving at a diagnosis.
So far, all I have is a list of facts that will compile and that I can then interact with, but I really don't understand how I am supposed to carry over the list of diseases from one input to the next. I also don't understand how to move from taking symptom input to suggesting tests, although maybe that will be evident once I understand how to do the symptom input portion.
I would really appreciate any help.
Thanks.
EDIT:
Could I take the two values from the SYMPTOM_IN call, use them to do something like symptom(X, fever, 150)., and assert the output from that to store it (like in the answer to this question)? Then maybe I can do the same thing for the next call and take the union of the two lists?
You want to create an expert system. There is a lot of info about it on the net. For example:
https://www.csupomona.edu/~jrfisher/www/prolog_tutorial/2_17.html
http://www.amzi.com/ExpertSystemsInProlog/02usingprolog.php
There is also a lot of good info on Stack Overflow.
In short: you need to know how to use assert and retract in proper way.
Um so I was in for a little bit of a surprise tonight. I spent a good 20 mins trying to figure out why I was able to submit a form knowing that what I entered into the recaptcha field was invalid. Is it true that you don't need to input the exact words it displays? If it shows me two words and I misspelled one of the words, I still pass validation? Same goes if "hello world" and I input "hell man" it still works.
With recaptcha, you are only tested on one of the words, while the other is used to help computers in scanning printed material. So you only need to get one right to pass (which one you need is random). :D
the recaptcha site describes why this is. You need to get one of the two words correct; only recaptcha knows which one.
But if a computer can't read such a
CAPTCHA, how does the system know the
correct answer to the puzzle? Here's
how: Each new word that cannot be read
correctly by OCR is given to a user in
conjunction with another word for
which the answer is already known. The
user is then asked to read both words.
If they solve the one for which the
answer is known, the system assumes
their answer is correct for the new
one. The system then gives the new
image to a number of other people to
determine, with higher confidence,
whether the original answer was
correct.
I am trying to write a script that does a zip code look up at the USPS.
URL="http://zip4.usps.com/zip4/citytown_zip.jsp". The data gets submitted by POST is:
zip5=YOURZIPCODE&submit.x=3&submit.y=22&submit=Find+ZIP+Code
The part I am having a hard time finding is how these numbers get generated:
submit.x=3
submit.y=22
The above two always "submit" values for X and Y always change. I can figure out
those number get put into the string.
Any thoughts would be greatly appreciated.
Those are the coordinates for a image-button click. Their values just give the mouse position on the button when it was clicked. In this case, they are going to be meaningless, just make them both 1 or something.
"Users may view and download material from this site only for the following purposes: (a) for personal, non-commercial home use"
http://www.usps.com/homearea/docs/termsofuse.htm?from=global_footer&page=termsofuse
From the link above.
As the first answer says, that is just the USPS trying to keep anyone from building an automated script to access data through that form. They expect slightly different numbers for each request from a given IP address.
"when you can prevent someone from doing something, you can get paid to allow them to get things done"
Just put in random numbers between 1 and the max size of the image button and it will work.
And I would not bother trying to do it "legally", their legal terms make no sense:
