DOMDocument removes HTML tags in JavaScript string

I'm developing PHP applications for quite a while now. But this one realy gets me struggled. I’m loading complete HTML pages using the DomDocument. These pages are external and may contain JavaScript. This is beyond my control.

On some pages things were not rendered the way it supposed to when it came down to basic HTML formatting in JavaScript strings. I've wrote down an example which explains it all.

<?php
$html = new DOMDocument();

libxml_use_internal_errors(true);

$strPage = '<html>
<head>
<title>Demo</title>
<script type="text/javascript">
var strJS = "<b>This is bold.</b><br /><br />This should not be bold. Where did my closing tag go to?";
</script>
</head>
<body>
<script type="text/javascript">
document.write(strJS);
</script>
</body>
</html>';

$html->loadHTML($strPage);
echo $html->saveHTML();
exit;
?>

Am I missing something?

Edit: I've changed the demo. Changing the LoadHTML to LoadXML doesn't work anymore now and the output of the demo will pass w3c validation. Also adding the CDATA block to the JavaScript doesn't seem to have any effect.

How to insert n random NaN consecutive and no consecutive data by month?

I have this df:

       CODE      DATE     PP
0      000130 1991-01-01  0.0
1      000130 1991-01-02  1.0
2      000130 1991-01-03  2.0
3      000130 1991-01-04  2.0
4      000130 1991-01-05  1.1
      ...        ...  ...
10861  000142 2020-12-27  2.1
10862  000142 2020-12-28  2.2
10863  000142 2020-12-29  2.1
10864  000142 2020-12-30  0.4
10865  000142 2020-12-31  1.1

I want to have at least 3 consecutive nans and 5 non consecutive nans in df['PP'] by each df['CODE'] with their corresponding df['DATE'].dt.year and df['DATE'].dt.month so i must convert random values of df['PP'] to NaN to reach that 3 consecutive and 5 non consecutive NaNs. Expected result:

       CODE      DATE     PP
0      000130 1991-01-01  0.0
1      000130 1991-01-02  NaN
2      000130 1991-01-03  NaN
3      000130 1991-01-04  NaN
4      000130 1991-01-05  1.1
5      000130 1991-01-06  2.1
6      000130 1991-01-07  NaN
7      000130 1991-01-08  2.1
8      000130 1991-01-09  0.4
9      000130 1991-01-10  NaN
...    ...    ...         ...

Important: consecutive nans + alternate nans = 5. So i can have 3 consecutive nans per month inside the 5 nans. And if i already have n nans in a month, i should only add the difference to reach 5 nans. For example if i already have 2 nans in a month i should only add 3 consecutive nans. If i already have 5 nans in the month the code should do nothing with that month.

I tried this:

df['PPNEW']=df['PP'].groupby([df['CODE'],df['DATE'].dt.month]).sample(frac=0.984)

But i can't get the exact quantity of NaNs (only in percentage and months sometimes have 30-31 days) and i can't get consecutive NaNs.

Would you mind to help me?

Thanks in advance.

BadWindow crash in tkinter after calling glfw.init()

I have the following code, which works on Windows, but crashes on Linux with X11:

#! /usr/bin/env python3
"""Tkinter crashes on X11 when popup windows
are closed after calling glfw.init()
"""

from sys import exit

from tkinter import Tk

        showinfo('Close me', 'I dare you')


def main():
    """Run the script."""

    MainWindow().mainloop()


if __name__ == '__main__':
    main()

After clicking OK in the message box on Linux/X11, the program crashes with:

X Error of failed request:  BadWindow (invalid Window parameter)

  Resource id in failed request:  0x4c0000a
  Serial number of failed request:  778
  Current serial number in output stream:  778

The addresses vary after each run, but the overall error stays the same.
I was able to reduce the problem to the call of glfw.init() which results in subsequent closing of tkinter Windows to crash the program. However, this does not happen on Windows systems.

Some system info:

$ uname -r

$ pacman -Q xorg-server
xorg-server 21.1.3-6
$ echo $XDG_SESSION_TYPE
x11
$ pacman -Q glfw python-glfw
glfw-x11 3.3.6-1
python-glfw 2.1.0-2

Why is this program crashing on my system?
What can I do to make it run just like on windows?

python telegram bot ignoring messages

From time to time my telegram bot seems to ignore messages. Unfortunately it never happens to me but to other users and only when they are asked to upload a photo or pdf. Sometimes the corresponding handler is not called. The problem persists even when the MessageHandler has no filters at all. I am using python-telegram-bot v13.7.

Please find below a minimal sample. It should print "receiving something" whenever the handler is called but sometimes it doesn't.

Is there anything I can do?

EDIT: modified the sample to be a MWE (you have to provide a valid telegram bot ID). Most of the time it works just fine but sometimes it will fail and not print "receiving something" although the user uploaded some document (mostly images).

maxLength causes a crash while a longer text is pasted in

I have declared in my fragment a textInputLayout which contains an edit text with parameters

     android:inputType="textCapCharacters"
     android:maxLength="3"
     android:maxLines="1"

and it works correctly on most devices, it "survives" while user is trying to input more than 3 characters, but IF user tries to paste a string, which contains more than 3 characters it ends up crashing.

"java.lang.IndexOutOfBoundsException: setSpan (0 ... 10) ends beyond length 3"

and just to be clear, the app doesn't crash after pasting longer strings on most of the devices but on some it does, and thus is why I'm here, is there any way I could prevent that?

How can I select text between anchors and highlight them as such?

I have some HTML that looks roughly like this:

<a name="a3end" type="end"></a>
</div>

In other words, anchors used to mark starts and ends of highlighted areas. They are irrespective of their locations in <div> or other containers. The highlights are overlapping, thus a1start corresponds to a1end.

I'm trying to figure out a way to highlight them, going from start anchors to end anchors, and ignoring all the HTML in between. So, one highlight from a1start to a1end. Another, overlapping highlight from a2start to a2end, and so on.

Note again that these are overlapping, so I can't just use spans, because then how would a given </span> know that it's the end of, e.g., a2 rather than a closer one at a1?

In other words, think of this structure:

<highlightA>
Here is something highlighted in A.
<hightlightB>
Here is something highlighted in A and B. 
</hightlightA>
Here is something only highlighted in B. 
</hightlightB> 
Here is something not highlighted.

I would usually just transform these <a> tags to <span> and </span>, and then highlight them with CSS: span { background-color: yellow }. But that would produce overlapping tag sets, no? Which is illegal in the HTML/XML world?

So I need to use JavaScript to identify these markers, figure out which ones match, and highlight those spans of text, without trying to edit the HTML. In other words, I need to overlay some highlighting on top of the page, without messing with this markup.

I'm a JavaScript beginner, so go easy on me, please.

Edit: Here's a Codepen I put together which illustrates this problm a little better, and tries to implement the (non-working) solution below. It uses different highlight colors to show how the overlapping highlights aren't working.

When Intent is received in Xamarin, ensure that only one instance is running at any given time

The Xamarin App sends and receives requests to the "central microservice" every 5 seconds using a timer. We can do an "action" in two ways: using intent from another app or scanning a QR code from a web app. Our app sends a request to the "central microservice" when scanning a QR Code or receiving an Intent, and receives a request from the "central microservice" after "5" seconds.

When scanning a QR code, the "central microservice" sends a single request per call. However, while using Intent from another app, you may receive an additional request. Apps are executing in two instances on Intent.

In the AndroidManifest.xml file, I tried adding android:launchMode="singleInstance" and android:launchMode="singleTask".

In MainActivity.cs, I inserted LaunchMode = LaunchMode.SingleTask and LaunchMode = LaunchMode.SingleInstance.

In Another App (the Intent comes from), I inserted intent.addFlags(Intent.FLAG ACTIVITY REORDER TO FRONT).

Both Apps are still active (can be seen by minimizing the app). How can I ensure that only one instance of the app is running at any given time when the Intent is being received?

Is there any way to solve that issue.

Or did i choose the ser correctly like passing query params correctly?

Get python3 package metadata given source directory without installing

I am trying to get some package metadata (name, version) given a path to the source directory without installing said package.

These work, using setup.py if you're sitting in the root directory:

> python3 setup.py --name
my_package_name

> python3 setup.py --version
0.1.0

However, I have been cautioned away from using python3 setup.py commands -- and indeed see a warning:

.../lib/python3.7/site-packages/setuptools/installer.py:30: SetuptoolsDeprecationWarning: setuptools.installer is deprecated. Requirements should be satisfied by a PEP 517 installer.
  SetuptoolsDeprecationWarning,

I know pip show my_package_name will print various metadata about a package (including name/version), however it requires that the package is installed into the environment. It also doesn't take a source directory and thus requires I already know the name of the package I want the info on.

> pip show .
WARNING: Package(s) not found: .

> pip show my_package_name
WARNING: Package(s) not found: my_package_name

> pip install .
...

> pip show my_package_name
Name: my_package_name
Version: 0.1.0
...
...

Is there any equivalent pip command (or other tool) that will show me the version of a package given the source directory without actually installing the package?

Thanks in advance!

How do cookie consent banners work on the background? Can a website that sets 3rd party cookies on another website ask to allow its cookies?

I'm working on a hobby project. The project is basically an integrable live support service. To describe my questions easily, I will call my service service.com and call the website that uses my service website.com. I'm thinking on implementing session management to restore disconnected visitors chat. To do that I'm planning to use cookie based session management. If owner of the website.com wants to use my service I will provide them a JavaScript file which will inject some HTML on the body, style tags on head and implement interaction. All the website.com's have to do will be importing that JS file and calling a function defined by that JS file. To set 3rd party cookies on that website.com from my service.com I will use this request/response. When website.com requests my JS file from service.com, my service will respond the request with the JS file along with a cookie to manage visitor's sessions. This way service.com will set 3rd party on website.com's visitors.

1st Question: Could this stage of setting cookie on website.com's visitor done on the front-end with that requested JS file or locally (from the website.com's web server) requested JS file? Would that still be a 3rd party cookie since it would be set on the front-end of the website.com?

2nd Questios: My other question is about cookie consents. Can a website that sets 3rd party cookies (e.g service.com) on some other website (e.g website.com) ask to allow their cookies on that website.com? In other words, can I ask website.com's visitors to allow only 3rd party cookies that are set by service.com with the JS file I serve/give to website.com? Would that be legal?

3rd Question: How do cookie consent banners work behind the scenes? What happens when you accept/deny all of the 3rd party cookies used on a website? Or what happens when you filter and accepy only a few of them? How does the process of allowing/disallowing work? Is there some kind of JavaScript that is triggered when you click that "Accept" button or "Decline" button? You can provide me any resources on this topic.

Thanks!

const pubKey = process.env.PUB_KEY
const buff = Buffer.from(pubKey).toString('base64');
console.log(buff)

Using it in the createPublicKey method here

crypto.createPublicKey({
                key: buff,
                format: 'pem',
            });

Any idea what could be going wrong? TIA

I am trying to display video stream from opencv to pyqt5 interface but my code is not working

I am trying to display video stream from opencv to pyqt5 interface.

Annotate a function argument as being a specific module

I have a pytest fixture that imports a specific module. This is needed as importing the module is very expensive, so we don't want to do it on import-time (i.e. during pytest test collection). This results in code like this:

@pytest.fixture
def my_module_fix():
    import my_module
    yield my_module

def test_something(my_module_fix):
    assert my_module_fix.my_func() = 5

I am using PyCharm and would like to have type-checking and autocompletion in my tests. To achieve that, I would somehow have to annotate the my_module_fix parameter as having the type of the my_module module.

I have no idea how to achieve that. All I found is that I can annotate my_module_fix as being of type types.ModuleType, but that is not enough: It is not any module, it is always my_module.

Why do I get UNKNOWN/CUSTOM URL SCHEME error in React Native Expo Google/Facebook login?

I have a react native expo managed workflow project with Firebase backend set up. On android emulator facebook and google login WORKS with firebase, however when I release the apk (expo build:android) I get the following error during redirect: "UNKNOWN/CUSTOM URL SCHEME"

I use the following packeges: Google with expo-auth-session Facebook with expo-facebook

Since it works in emulator, I am pretty sure my Secrets, ID's and redirect URL's are okay, it redirects me without any problem. Also firebase created the google cloud profile for me, I just added the valid Oauth redirect URI's to my WEB ID settings. Same for facebook, added the firebase redirect URL, as well as the expo one.

I tried to add "scheme":"myapp" to app.json, but no luck. Not sure what to do...

import {GoogleAuthProvider, FacebookAuthProvider, signInWithCredential} from 'firebase/auth';
import * as Facebook from 'expo-facebook';
import * as Google from 'expo-auth-session/providers/google';
import * as WebBrowser from 'expo-web-browser';

        // scheme: 'com.graphite.ekisallatkonyv',
        useProxy: true,
      },

  );

    if (response?.type === 'success') {
        const { id_token } = response.params;
  
        const credential = GoogleAuthProvider.credential(id_token);
        signInWithCredential(auth, credential)
        .then((result) => {
            addDefaultData(result.user.uid)
        });
    }
  }, [response]);


const google_login_ButtonClick = async() => {
    promptAsync({useProxy: true,showInRecents: true})
}


const facebook_login = async() => {
    try {
        await Facebook.initializeAsync({

Is there anyway we can run dart code while in terminated or background state?

I'm currently working on an App which have video calling integrated in it. I'm using Flutter language to build my app but I want my app to be Like WhatsApp. I want to have the same functionality for example when someone calls you the calling UI appears. I used CallKeep and WorkManager packages but those did not helped at all. If anyone have a solution for that please let me know! Thank you!

    }
  }
}

as the id get changed and I want to match every-time with the mediaObj object and replace the value if there is multiple or single media file exits but if the media id does not match with mediaObj then it should delete the that object as you can see in mediaAccess id 1000 does not match with the mediaObj so it should delete it

as the same applies with the entries if I get the media replace code then I can try with the entry code too

Extended Logout in MVC 5

Extending logged in time as per user's choice.

Scenario: The ASP.NET MVC 5 web application is hosted in Azure WebApp WebConfig is set to timeout in 60 minutes of no requests made to the server as shown below

WebConfig:

<authentication mode="Forms">
      <forms loginUrl="~/Account/Login" timeout="60" slidingExpiration="true" name="MYAUTHDV" cookieSameSite="None" requireSSL="true" />
</authentication>

In the login screen, we would like to provide a CHECKBOX and if user ticks it and login, the webapp should not log them out for next 12 hours even if there is no activity.

So far, I have tried a javascript timer running on the _layoutpage.chtml and a local storage time value registered at loggged in time at the client side. The javascript timer will ping to the server every 20 minutes to keep the login alive. This is not always working for multiple reasons like browser, machine sleep mode, hard disk turnoff internet interruptions and other unknown reasons as well etc. There is also an issue we have to overcome regarding sliding expiration vs javascript pinging .https://ift.tt/1xWMQDA I am also open to solutions involving server handling as well. Hoping a client side solution will incur less modification in our existing app.

Python Eclipse Paho Client - TLS Connection to MQTT Broker Exception: No ciphers available

I am trying to create a connection to a TLS (TLSv1) secured MQTT Broker(Rabbitmq with MQTT Plugin enabled) with the python implementation of the eclipse paho client. The same works fine with the MQTTFX application which is based on the java implementation of paho. For this i am using self signed certificates.

    Java version uses: 
    CA-File: ca_certificate.crt 
    Client Certificate client_cert.crt  
    Client Key File: client_key.key

    Python Version should use:  
    CA-File: ca_certificate.pem 
    Client Certificate: client_cert.pem  
    Client key file: client_key.key

I tried to establish a connection like this:

    import ssl
    
    import paho.mqtt.client as paho
    
    # Locations of CA Authority, client certificate and client key file
    ca_cert = "ca_certificate.pem"
    client_cert = "client_certificate.pem"
    client_key = "client_key.pem"
    
    # Create ssl context with TLSv1
    context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
    context.load_verify_locations(ca_cert)
    context.load_cert_chain(client_cert, client_key)
    
    # Alternative to using ssl context but throws the exact same error
    # client.tls_set(ca_certs=ca_cert, certfile=client_cert, keyfile=client_key, tls_version=ssl.PROTOCOL_TLSv1)
    
    client = paho.Client()
    client.username_pw_set(username="USER", password="PASSWORD")
    client.tls_set_context(context)
    client.tls_insecure_set(False)
    client.connect_async(host="HOSTNAME", port="PORT")
    client.loop_forever()

Which results in the following error:

    ssl.SSLError: [SSL: NO_CIPHERS_AVAILABLE] no ciphers available (_ssl.c:997)

Could it be that I need to explicitly pass a cipher that the broker supports or could it be due of an older openssl version? I am a little bit lost right now, maybe someone has a clue on how to solve this.

Edit: I got it to work by myself but still not sure why exactly it works now.

Changed context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
to context = ssl.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
Changed client.tls_insecure_set(False)
to client.tls_insecure_set(True)

How do I send SMS using the adb shell command on all versions from Android 6 to Android 12?

I'm trying to send messages using adb shell commands. I sent on Android 10 but not on Android 11. I tried everything but without success. I found source code of isms service for android 11 here. I have 2 more Android 11 phones and when I test them the result is the same. To test that my shell commands are working on the device, I tried the input command and it does. I read this and still it didn't help.

The command I use:

adb shell service call isms 7 i32 0 s16 "com.android.mms.service" s16 "%number%" s16 "null" s16 "%message%" s16 "null" s16 "null"

Output of this command:

Result: Parcel(00000000 '....')

Can someone help, how do I send messages with adb shell commands on Android 11?

(I tried on Android 12 and result is same)

Typescript Generics for nested array of objects

Hello i am trying to add correct type to object with nested values.

Here is code in sandbox: https://codesandbox.io/s/0tftsf

interface Product {
  name: string,
  id: number
  productList?:ProductItem[]
}

interface ProductItem { 
  color: string, 
  size: number 
 }


type IValidation<T> = {
  field: keyof T
  nestedValidations?: IValidation<
    Pick<
      T,
      {
        [K in keyof T]-?: T[K] extends object ? K : never
      }[keyof T]
      >
    >[] // THIS IS IMPORTANT FOR QUESTION!
  validators?: (any | any | any)[]
}

export async function validateIt<T>(payload: T, validations: IValidation<T>[]): Promise<
  Partial<{
    [key in keyof T]: string[]
  }>
  > { 
    return Promise.resolve(payload);
  }

const product: Product = {
  id: 1,
  name: 'playstation',
  productList: [{
    color: 'red',
    size: 32
    }
  ]
}

const test = validateIt<Product>(product, [
  {
    field: "productList",
    validators: [],
    nestedValidations: [
      {
        field: 'color',
        validators: []
      }
    ]
  }
])

So getting type error and overall i am trying to find correct type for nestedValidations property, which should match interface Product

Android databinding generated files disappears when coding

I am facing a strange problem when Fragment*Binding files are deleted while I am writing code (all references become unresolved, generated files absent in files system) that can be fixed by clean project-> make the project but it is time-consuming.
Such behavior occurs 3-4 times per hour. Originally I thought I might be deleted by antivirus software, but I checked that all paths related to development are in Av exceptions. Android studio bumblebee latest updates (happened few updates before too)

How to Create a Tamil Phonetic keyboard inputs in python?

For Example: If I press "K" in textbox1, then my textbox1.text will change into the Tamil letter "க்", if I press "Ku" then textbox1.text will be replaced by the Tamil letter "கு",, if I press "kuu" then textbox1.text will be replaced by the Tamil letter "கூ" And then If I press "m" then the Tamil letter "ம்" will be added to the previous letter "கூ" and now textbox1.text becomes "கூம்"

In my textbox.text, my first character is "A", not found in dictionary, so need not process that character and display as it is.

In my textbox.text, my second input word is "k", which is found in my dictionery and also "k" is the main Word. Now My processed word is "A"+"k", my textbox is replaced as follows, "A" + "Apple" = AApple.

In my textbox.text, my third charcter is "a", Now my processed word is "ka", its found in dict . so replaced with that equivalent value "Banana". Now My processed word is "A"+"ka", and now my textbox.text as follows : "A"+"banana" = Abanana.

In my textbox.text, my fourth charcter is "a", my processed word becomes "Kaa" its equvilient value is "citrus", now my processed word is "A"+"kaa" , its equvlient value is "A"+"citrus" = "Acitrus"

In my textbox.text my fifth input character is "m", now my processed word is "kaam",not found in dictionery. Now we split character "m" and check it in dict, whether its found or not, if Found, then we replace its equvilent value. Now My processed word is "A"+'kaa'+"m" and its vaule is "A"+"citurs"+"is", my textbox.text as follows "Acitrusis"

sixth input word is "a", now my processed character is "A"+"kaa"+"ma" equvilaent value is "A"+"citrus"+"more". Textbox.text become "Acitrusmore"

Now, if I press charcter "i" not found in "m" set. so we split "i" sepreately and check it in dict, if found, replace that value or leave as it is.

If 7th input character is " space bar" then process will end.

if my 8th input charcter is some english alphabet, once agin start process and replace equvilaent value and so on

How to pass focus from an iframe to next focusable element in host page?

Background

I have an iframe widget which will be embedded in other pages - I have no prior knowledge of the host page's structure and code, and the iframe will be cross-domain and likely sandboxed.

My goal is to give the iframe widget a single tab stop - after focusing on it there's a dedicated key combination to "enter" the widget, but normal tabbing should skip forward to the next focusable element in the host page.

Question: After the iframe receives focus and a new tab keypress is detected, how can I pass the focus to the host page's next focusable element?

Simple example:

<!-- host page -->
<button> first button </button>
<iframe src="myIframeWidget.com"/>
<button> second button </button>

In the above, if the first button is focused, then the expected behavior is that on first tab the iframe will receive focus, and on the next tab the second button will receive focus (skipping all focusable elements inside the iframe).

Once the iframe is focused and tab is pressed, I need to pass the focus from my iframe to the second button.

Notes

Since my iframe DOM is rather large, I don't want to set tabindex=-1 to all internal focusable elements.
At the time of writing, aria-hidden="true" does not remove an element or its descendants from the focus sequence. I'm not aware of any other aria attribute which removes an entire subtree from the focus sequence.
A pure JS solution is preferred to one relaying on external packages.
I'll also need to handle reverse-tabbing, but I assume that the same approach for forward-tabbing will apply - if there are any crucial differences, please mention them in your answer if possible.
There's an edge case where there isn't anything focusable after the widget - typically in those cases the browser will focus on the address bar buttons - if there's a way to handle that it'll be great to know, but this probably should be handled in a separate question.

Thanks!

    document.body.innerHTML = simpleVarDisplaySite({
        heading: myNewHeading,
        pugObject: newSimpleObject,
    });
}

I would like to have pug variable: pugObject updated when the checkbox is checked / unchecked onChange event, and see the updates in my browser, which I have tried with:

document.body.innerHTML = simpleVarDisplaySite({
  heading: myNewHeading,
  pugObject: newSimpleObject,
});

But that does not work.

I know that client-side is handled rather differently from server-side, but I am soo hoping that there is a solution to my specific problem.

Please note that I am a nood with javascript and pug, and I am very open to any and all suggestions to better achieve my goal.

My File structure:

server.js
views
  simpleVarDisplay.pug
static
  scripts
    pugVarUpdater.js

PS: I have had a look at: use client-side js variable in pug And that did not help me.

Your assistance and guidance is much appreciated.

Passing a promise in a Custom Event detail

I'm trying to pass a promise object via a Custom Event's detail property.

Then I try to call this (either from scriptB or from a 3rd unrelated script, after both scriptA and scriptB were loaded):

document.dispatchEvent(new CustomEvent('eventA'));

When I print the detail object in scriptA before dispatching the event, it shows the promise object correctly, but it doesn't arrive to to scriptB at all - the detail property arrives as null.

Am I missing something here?

When I create a sandbox to replicate it, it works fine.

However, in my actual code, it doesn't. here are screenshots from Chrome debugger:

In the dispatch part:

In the listener part:

If I don't include the response (which is a Promise object) in the dispatched detail, everything arrives correctly.

Multi-tenant authentication flow

How do companies handle authentication in their multi-tenant web apps?

Essentially I have a single PostgreSQL database instance with many tables. Each table has a workspace_id column which I will use to use to grant/deny access. You can think of a workspace as a client and a single user can be associated with multiple workspaces.

My initial thought was to:

Use the frontend app and let the user send the email and password to the backend.
Backend validates details and returns all the workspaces the user belongs to.
The frontend app displays the workspaces.
User selects the workspace they want to login into. The id of the workspace and the user details that were passed in step 1 is again to the backend.
The backend validates again all the details and issues a jwt token containing the user details and the workspace id.
Later when the user tries to access any resource I will extract the workspace id from the token to check if the user has access to a resource or not.

I am halfway through implementing what I've described above but I am not sure if that's the best approach. What do you think?

Record Video and Screen together and overlay with Javascript

I want to record a user's screen alongside their webcam and display the result as an overlay, like this:

I assume that while recording I can display the multiple streams in two separate video elements and overlay them with CSS.

However, how do I save the result as an overlay of the two videos?

Efficiently count all the combinations of numbers having a sum close to 0

I have following pandas dataframe df

column1 column2 list_numbers          sublist_column
x        y      [10,-6,1,-4]             
a        b      [1,3,7,-2]               
p        q      [6,2,-3,-3.2]

the sublist_column will contain the numbers from the column "list_numbers" that adds up to 0 (0.5 is a tolerance) I have written following code.

def return_list(original_lst,target_sum,tolerance):
    memo=dict()
    sublist=[]
    for i, x in enumerate(original_lst):
    
        if memo_func(original_lst, i + 1, target_sum - x, memo,tolerance) > 0:
            sublist.append(x)
            target_sum -= x          
    return sublist  

def memo_func(original_lst, i, target_sum, memo,tolerance):
    
    if i >= len(original_lst):
        if target_sum <=tolerance and target_sum>=-tolerance:
            return 1
        else:
            return 0
    if (i, target_sum) not in memo:  
        c = memo_func(original_lst, i + 1, target_sum, memo,tolerance)
        c += memo_func(original_lst, i + 1, target_sum - original_lst[i], memo,tolerance)
        memo[(i, target_sum)] = c  
    return memo[(i, target_sum)]

Then I am using the "return_list" function on the "sublist_column" to populate the result.

target_sum = 0
tolerance=0.5

df['sublist_column']=df['list_numbers'].apply(lambda x: return_list(x,0,tolerance))

the following will be the resultant dataframe

column1 column2 list_numbers          sublist_column
x        y      [10,-6,1,-4]             [10,-6,-4]
a        b      [1,3,7,-2]               []
p        q      [6,2,-3,-3.2]            [6,-3,-3.2]  #sum is -0.2(within the tolerance)

This is giving me correct result but it's very slow(takes 2 hrs to run if i use spyder IDE), as my dataframe size has roughly 50,000 rows, and the length of some of the lists in the "list_numbers" column is more than 15. The running time is particularly getting affected when the number of elements in the lists in the "list_numbers" column is greater than 15. e.g following list is taking almost 15 minutes to process

[-1572.35,-76.16,-261.1,-7732.0,-1634.0,-52082.42,-3974.15,
-801.65,-30192.79,-671.98,-73.06,-47.72,57.96,-511.18,-391.87,-4145.0,-1008.61,
-17.53,-17.53,-1471.08,-119.26,-2269.7,-2709,-182939.59,-19.48,-516,-6875.75,-138770.16,-71.11,-295.84,-348.09,-3460.71,-704.01,-678,-632.15,-21478.76]

How can i significantly improve my running time?

how to send audio stream between child processes in nodejs

How do i properly send stream to a child process. I am trying to stream audio from client to server using this method

I am getting the audio stream from client


const ss = require('socket.io-stream');
const socketIo = require('socket.io');

server = http.createServer(app);
io = socketIo(server);

const child_process = childProcess.fork('./child_process.js');


io.on('connect', (client) => {


    // when the client sends 'stream-transcribe' events
    // when using audio streaming
    ss(client).on('stream-transcribe', function(stream, data) {
     
    var combine_data = {
            "data": data,
            "stream": stream,
            "event":"new_stream"
          }
    
     child_process.send(combine_data)


  }


}

Applying LiveServer Logic for Tkinter File

The people who are familiar with the Live Server of VS Code, would have easily understood what is the main motive of this question.

But for others, here's the explanation:

Main motive of Live Server is to Automatically Reload Your Site on Save in web development! (Which get changed for python tkinter).
When ever I change something in my python file which contains tkinter code, the change should be reflected in the main window (the main window should not re-open to reflect the changes).

I have tried to search on web as well as on stack over flow, but all the results are for updating value in entry, label, buttons etc. But what I want is, the whole window should be updated when ever I change something in my main file, and the main window should not be reopened to do so. So in short, updating whole window without closing it, on every changes in the main file or automatically reload your program on save without reopening!

What have I tried?:

I tried to detect change in file using os.getsize which satisfied the first part of my question, but however I am not able to solve the second part i.e window should not be closed.

import os
main__tkinter_filename="myfile.py"
initial_filesize=os.path.getsize(main_tkinter_filename) # Getting size of the file for
                                                        # comparison.
while 1:
    final_filesize=os.path.getsize(main_tkinter_filename)
    if final_filsize<intial_filesize or final_filesize>initial_filesize:
        webbrowser.open(main_tkinter_filename)

How do I show a custom Android notification using Flutter widgets?

I want to show custom notifications on Android using Flutter widgets? I'll like to know if that is possible.

What I've done:

I tried using showing a Flutter widget in an Android Fragment and display that Fragment using RemoteViews for custom Android notifications.

A notification shows but it does not include the Flutter widget. See screenshot below:

Code:

 var newFlutterFragment: FlutterFragment = FlutterFragment.withCachedEngine("my_engine_id")
     .shouldAttachEngineToActivity(false)
     .build()
 if (fragmentManager != null) {
     fragmentManager
         .beginTransaction()
         .add(
             R.id.fragment_container,
             newFlutterFragment,
             TAG_FLUTTER_FRAGMENT
         )
         .commit()
 }



 val notificationLayout = RemoteViews(packageName, R.layout.activity_layout)
 val notificationLayoutExpanded = RemoteViews(packageName, R.layout.activity_layout)


 var builder = NotificationCompat.Builder(this, CHANNEL_ID)
     .setSmallIcon(R.drawable.ic_bg_service_small)
     .setCustomContentView(notificationLayout)
     .setCustomBigContentView(notificationLayoutExpanded)
     .setPriority(NotificationCompat.PRIORITY_DEFAULT)

 var notificationId = 1;

 with(NotificationManagerCompat.from(this)) {
     // notificationId is a unique int for each notification that you must define
     notify(notificationId, builder.build())
 }

How can i improve the performance of my python task?

I have a problem. So I have a task that runs every time when a user writes a chat message on my discord server - it's called on_message. So my bot has many things to do in this event, and I often get this kind of error:

Task was destroyed but it is pending!
task: <Task pending name='pycord: on_message' coro=<Client._run_event() done, defined at /Bots/gift-bot/discord/client.py:374> wait_for=<Future pending cb=[<TaskWakeupMethWrapper object at 0x7f68a7bdfc10>()]>>

So I think if I want to fix this, I need to speedup my code. But sadly, I don't have any clue how i can do it to fix this error.

During handling of the above exception, another exception occurred:

requests is 2.24.0 and ssl.OPENSSL_VERSION says "OpenSSL 1.1.1h 22 Sep 2020". I can not update the packages.

How can I get a meaningful error or error message that tells me that the certificate is expired?

from How to get more details on a requests.exceptions.SSLError?
