skull | Object-oriented-like Bash framework | Script Programming library

I am having a problem with my code an would be highly grateful for some advise. I want the yellow square to stay at the left side, having it´s own column just as it is now but I want the square to be fixed on the screen while scrolling down. Every time I write position:fixed or write both position:left:fixed;" in my code it takes over and melts everything together into one column.

Here comes the code!

I'm trying to perform a skull stripping with simpleITK in python. I'm using the StripTsImageFilter function as follows:

I am trying to externalise my runtime data from my applications to be saved in OpenMediaVault shared folder. I was able to create shared folder and configure NFS or at least I think so. The config I see in OMV/Services/NFS/Shares is:

This is my first stack overflow question, so if I am presenting something wrong, please let me know. I am pretty new to computer programming, so I just have a small webpage where I am just implementing things that I am learning.

I made a little quiz with random trivia multiple choice questions you can take if you press a button. I am using window prompts to ask the questions and get the answers, and I have all of the questions and answers stored as objects with question/prompt and answer pairs. All of those objects are stored in an array in a variable called shortQuizPrompts. I already have the quiz working and everything, aka., It tells you after every question if you got the answer to that question right or wrong, and it gives you a grade afterwards... I also have it set up so that if you enter an answer that is not "a", "b", "c", or "d", it lets you know that it isnt a valid answer. Those sorts of things.

As of right now, you can choose how many questions long you want the quiz to be out of the 24 total questions I have so far. It just asks the questions in the order that they are stored in the array. For example, you will never be asked the last question in the array if you do not choose for the quiz to be the full 24 questions long. However, I want to make the quiz ask the questions in a random order, while also removing those questions from the array as to not ask the same question multiple times.

I have tried increasing the iterator while looping through the array to a random number from 0 to the length of however many questions they chose. Then checking to see if the iterator was larger than the length of the number of questions they chose, it would decrease the iterator until it found a question that is still in the array that it could ask...

If anyone knows how to go about doing that, it would be great. Sorry for the long question btw. I am pretty new to coding, so this is probably a simple answer, but I digress. I'm pretty sure I did everything right. Thx.

I have a Lego mindstorms 51515 and like to program it with python.

There are some default image in the module I'd like to loop over and use.

The code is below

I would like to convert this image to gray scale in OpenCV and then find the settings to threshold it. I want to threshold the black spaces inside of the skull. Can someone write out a Python script using OpenCV?

I convert to grayscale with: gray = cv2.cvtColor(pic, cv2.COLOR_BGR2GRAY)

When I do (ret, thresh) = cv2.threshold(gray, 177, 255, cv2.THRESH_BINARY) I get a black image.

When I do (ret, thresh) = cv2.threshold(gray, 0, 255, cv2.THRESH_BINARY) the whole head becomes a white blob.

Question In R Shiny, when using

• renderUI
• uiOutput

to dynamically generate sets of controls, such as:

• checkboxes
• radiobuttons
• text boxes

how can I harvest those values or populate input by causing events?

As-is, those generated controls appear to be "display only". Making a selection, marking a checkbox, or entering data only updates the display, but no Event is created and the values are not populated into the "input" variable ( ReactiveValues ); thus, nothing is received by the Shiny server process.

If these control inputs are in-fact isolated, it completely undermines the point of dynamically creating controls.

Obviously, I'm hoping that this issue has been addressed, but my searches haven't turned it up.

In my specific case, the UI allows the user to:

1. Select and upload a CSV file.
2. The logic identifies numerical, date, and grouping columns, and produces 3 sets of radiobutton control sets. The idea is that you pick which columns you are interested in.
3. Picking a grouping column SHOULD return that columnID back to the server, where it will display a discrete list of groups from which to select. This fails, as the selections do not generate an Event, and the input variable (provided to server.R) only contains the ReactiveValues from the static controls.

That said, the display of the controls looks fine.

On the server.R side, I'm using code as below to create the radioButtons.

I tried to cluster my dataset using K-mean, but there is a categorical data in column 9; so when I ran k-mean it had an error like this:
