[Solved] Primeng, dynamically uncheck p-checkbox with pButton

Chris Asks: Primeng, dynamically uncheck p-checkbox with pButton
i originally found this question, which is really similar to my situation:

how to uncheck/check a primeng checkbox manually

and this is a StackBlitz where it shows my problem:

Angular Primeng P Checkbox Issue (forked) – StackBlitz

basically, i am looping through data that can be any length and displaying it in a table.

one of the columns just has a p-checkbox with (onChange), that when checked and unchecked, it passes in some parameters for me to keep track of in an array.

i am trying to then uncheck all the p-checkboxes with a button click.

i found another question/solution that mentioned using @ViewChildren, ElementRef, QueryList but it was having a problem trying to figure out what “nativeElement.checked” was.

and other questions/solutions i found involved knowing the length of the checkboxes beforehand, and using *ngFor through an array to display the correct amount of checkboxes. i tried to use similar logic with my setup, but couldn’t get it working either.

eoterochio Asks: Translate to text a Emoji Unicode String un python
I have a list of tweets that has been delivered as a csv. But when I read them, the emojis unicode has been converted as str and I can’t translate them to their real name (“waffle” or “heart”).

Code:
def load_csv(csv_name):
    path = os.getcwd()
    df = pd.read_csv(path + "/" + csv_name, header=0, index_col=0, parse_dates=True, sep=",", encoding="utf-8")
    return df

csv_name = "tweets_nikekaepernick.csv"
df = load_csv(csv_name)

text = df["tweet_full_text"].iloc[0]
text

Out[]: 'Hi <U+0001F602><U+0001F602><U+0001F480><U+0001F480><U+0001F480><U+0001F480>'

[Solved] Problem in using itertuples to iterate over a Pandas DataFrame

Carlos Asks: Problem in using itertuples to iterate over a Pandas DataFrame
I want to iterate over a Pandas DataFrame and I have read in other posts that a way to do it was to use intertuples. I do not know what I am missing, as I keep getting this error: ‘DataFrame’ object has no attribute ‘intertuples’. I need to iterate over the dataframe and do some operations with the values in the columns ‘Year’ adn ‘Month’, as the example below:

Code:
import pandas as pd

df = pd.DataFrame({'Year': [2018, 2019, 2020], 'Month': [6, 7, 8]})
for row in df.itertuples():
    print(row)

Sorry, please do not consider my question. There was a missspelling noted by Mahrkeenerh! But I learnt something new from ti7! Thanks!

[Solved] Under what circumstances does PHP’s openssl_random_pseudo_bytes return false?

CJ Dennis Asks: Under what circumstances does PHP’s openssl_random_pseudo_bytes return false?
The PHP documentation for openssl_random_pseudo_bytes says:

Return Values​

Returns the generated string of bytes on success, or false on failure.

What would cause openssl_random_pseudo_bytes to fail? Can this be manually triggered for testing purposes? I tried disabling the entire openssl PHP extension, but as expected that raised an error due to the function not being found.

alefisto Asks: I am trying to run this code I found in a book about neural networks in R
I am using the latest version of R and Rstudio. The code is as follows:

Saeed Ghezel Arsalan Asks: How to header display when scroll-up use react hooks
I used react.js Hooks with useState and useEffect, when I scroll-down and the screen comes down Header hides after 250 pixels. Now I want to know how to display Header using the react Hooks when I scroll up.

Code:
const Navbar = () => {
  const [show, setShow] = useState(false)
  const controlNavbar = () => {
      if (window.scrollY > 250 ) {
          setShow(true)
      }else{
        setShow(false)
      }
  }

  useEffect(() => {
      window.addEventListener('scroll', controlNavbar)
      return () => {
          window.removeEventListener('scroll', controlNavbar)
      }
  }, [])

and header:

Code:
 <header className={`active ${show && 'hidden'}`}></header>

css:

Code:
.active{
    height: 4rem;
    width: 100%;
    position: fixed;
    top: 0px;
    transition: 0.3s linear;
    display: flex;
    justify-content:stretch;
    align-items: center;
    background-color: #FFFFFF;
    border-bottom: 1px solid rgba(0, 0, 0, .1);
    z-index: 40;
    box-shadow: 0 2px 5px -1px rgba(0, 0, 0, .08);
    /* padding: 0 7%; */
}

[Solved] How to store version of a row where columns could change in the future?

RedLotus Asks: How to store version of a row where columns could change in the future?
I have a form(table) with several sections(one-to-many) that will get stored in a SQL database. I currently need to create versions of the form record(row) once it gets to a certain status or some requirements are met, not at every UPDATE. This form could also have columns added and removed in the following weeks/months so I cannot use the same table as it is used heavily in application logic. What can I use to keep track of my versions?

I’m leaning towards SDC Type 4: History table Slowly changing dimension – Wikipedia . Let me know if there are any things I’m overlooking or there are any other alternatives, I’d have to create several history tables by doing this method.

[Solved] Best way to detect corners of a plaque and reference object (Java, Opencv, Android Studio)

Lara Maria Asks: Best way to detect corners of a plaque and reference object (Java, Opencv, Android Studio)
first of all english is not my main language so I’m sorry for any mistakes and this is also my first time using stackoverflow.

About my problem: I’m doing a research project at my college where I have to create an app that is able to analyze an image of a plate and its reference object and return the width and height of that plate using a picture taken with the app. I joined the project after it started so the app has to be made in android studio using java. The thing is that my major is not in computer science so maybe I don’t have enough bag of knowledge to know where to look and would like to know if you have tips on what I have to search or anything that could help me

Here’s how the plaque will be displayed

Right now I’m doing the whole usual process of getting a object contour (threshold, blur, etc etc) and I have a really good threshold image x

I’m getting the contour of the plaque just fine but I’m having trouble with the reference object (the A4 sheet). I’m currently using Imgproc.approxPolyDP and the sheet proportion to ensure that the outline is that of the sheet and not some other outline of the plate, but if I can make it work for a specific photo it doesn’t work for the real time picture on the app.

So do you guys have any tips? Or should I talk to my teacher for him to make some concessions? I thought about making an interface where the user could select the right contours and then calculate the height and width values but my teacher is very difficult to accept changes in the project.

Thanks in advance!
