Can you write me some js code that does the following?
- go through each element that has the class "aditem-main--middle":
- with the element, extract the number of a child element with alphanumeric content with the class "aditem-main--middle--price-shipping" as a variable.
- with the element, extract the number of a child element with alphanumeric content with the class "aditem-main--bottom" as a variable.
- with the element, append some text to the cild element "aditem-main--middle--price-shipping".

When a user enters a contract address in the search bar of https://moonarch.app/, the website uses a tool called “Rugcheck” to scan the contract code. The Rugcheck tool looks for certain functions and patterns in the code that may indicate suspicious or malicious intent.
Rugcheck scans for a list of known vulnerabilities and looks for certain functions such as “transfer” and “approve” that can enable transactions and transfers of tokens. If the contract code contains any of these functions, the website may display a warning that the contract has “dubious” or “risky” functions.
For example, if the contract code contains the “transfer” function, it means that the contract has the ability to transfer tokens from one wallet to another. If the contract is a scam, the scammers could use this function to transfer all the tokens to their own wallet, leaving the investors with no value.
Similarly, if the code contains the “approve” function, it means that the contract can allow a third party to spend tokens on behalf of the owner. If the contract is a scam, the scammers could use this function to spend all the tokens on their own accounts.
Rugcheck also looks for certain patterns in the code that are commonly used in scams or “rug pulls”. For example, it looks for code that creates a large amount of tokens that can be sold by the scammers, or code that allows the scammers to change the contract rules after the sale, such as increasing the amount of tokens they hold.
If any of these functions or patterns are found in the contract code, the website displays a warning that the contract may be risky or dubious. This allows users to make an informed decision about whether to invest or not.
Based on the answer above, write a script or code that will perform the same functions as the script or code used in the https://moonarch.app/ resource. That is, it should display vulnerabilities that it finds in the token contract code

I have a C# app that contains wolflive.api and telegram.bot, this code: "else if (messageText == "/تشغيل")
{
string jsonFromFile = System.IO.File.ReadAllText("accounts.json");
List<AccountsList> accountsFromFile = JsonConvert.DeserializeObject<List<AccountsList>>(jsonFromFile);
List<WolfClient> clients = new List<WolfClient>();
await Task.WhenAll(accountsFromFile.Select(async item =>
{
var client = new WolfClient();
var loggedIn = await client.Login(item.Email, item.Password);
if (!loggedIn)
{
Telegram.Bot.Types.Message senddMessage = await botClient.SendTextMessageAsync(
chatId: chatId,
text: "فشل تسجيل الدخول على حساب: " + item.Email,
cancellationToken: cancellationToken);
return;
}
else
{
Telegram.Bot.Types.Message senddMessage = await botClient.SendTextMessageAsync(
chatId: chatId,
text: "تم تسجيل الدخول على: " + item.Email + "\n" + clients.Count(),
cancellationToken: cancellationToken);
}
clients.Add(client);
await Task.Delay(-1);
}));
var datas = JsonConvert.SerializeObject(clients);
System.IO.File.WriteAllText("running.json", datas);
}", clients list is null, solution?

Would you please get me the code of Implementation a tracking algorithm (ex: Opencv tracking algorithms) to track multiple objects in a video &
Use the object detection model and the tracking algorithm to formulate a video summarization algorithm that only selects the frames with motion in them.
but dont use DeepSort ,(KCF or any old methods) & motpy

I’m building a video game engine using C++ as the coding language and Vulkan for graphics. I am trying to set up a generic renderer using Vulkan that is flexible and will render objects based on a vector that is supplied to it. The renderer will also handle the creation of the window using GLFW and use GLM for all relevant math calls. I am using the ASSIMP library to load 3d models and animations.
Here is a portion of the code:
Renderer.h:

#include <vector>
#include <stdexcept>

#include "Mesh.h"
struct QueueFamilyIndices
{
std::optional<uint32_t> graphicsFamily;
std::optional<uint32_t> presentFamily;
bool IsComplete()
{
return graphicsFamily.has_value() && presentFamily.has_value();
}
};
struct SwapChainSupportDetails {
VkSurfaceCapabilitiesKHR capabilities;
std::vector<VkSurfaceFormatKHR> formats;
std::vector<VkPresentModeKHR> presentModes;
};
class Renderer

why this python code:
original = [0] * (m * n)
for i in range(0, len(original), n):
res.append(original[i : i + n])
is faster than this:
original = [0] * (m * n)
res = [[original[n * i + j] for j in range(n)] for i in range(m)]

The date and time started (Start:)
The execution time (Run:)
The error information (in the code wrapped by a context manager) (An error occurred:)
The trace format example when no errors occurred:
Start: 2021-03-22 12:38:24.757637 | Run: 0:00:00.000054 | An error occurred: None
The example in the case of a ZeroDivisionError exception
Start: 2021-03-22 12:38:24.758463 | Run: 0:00:00.000024 | An error occurred: division by zero
The log file name is passed as an argument to the text manager constructor. For example:
@LogFile('my_trace.log')
def some_func():
...
The log file has to be open in append mode to allow reopening the existing file and adding new information into this file if the same name is pointed.
When an exception happens, the error message has to be put in (An error occured): into the log and reraised upper.
Use the open built-in function to open the log file.

the TrialHandler class in the PsychoPy library can read CSV files and use them as a trial list. The TrialHandler object provides a convenient way to iterate over the trials in the CSV file and access the values of different columns:
from psychopy.data import TrialHandler
# Specify the path to the CSV file
csv_file = 'group_a_stim.csv'
# Create a TrialHandler object with the CSV file as the trialList
trials = TrialHandler(nReps=1, method='random', extraInfo=None, trialList=csv_file, seed=None, name='trials')
# Iterate over the trials and access the values of different columns
for trial in trials:
# Access values from the CSV columns
image_file = trial['image']
condition = trial['condition']
# Do something with the trial values
print(f"Image file: {image_file}, Condition: {condition}")
Imagine I have several participants and for each of them I have a row in my csv file with individual stimuli. Can TrialHandler read one row given a participant number?

Elaborate this with examples or instructions
9. Customize key bindings for the Build Output Panel: Go to Preferences > Key Bindings and add custom key bindings to open, close, or toggle the Build Output Panel.
10. Configure build output filters: Go to Tools > Build System > New Build System to create a custom build system and configure “output_patterns” to filter build output selectively. This way, you can limit the information displayed in the Build Output Panel based on your preferences.

In unreal engine 4, I want to create an scope that simulates a real one and without using the render target, but due to the camera Field of view when you look through the scope the viewing area is very narrow. is it possible to write a custom HLSL shader code using Custom expression node in the scope material to clip only the narrow area through the scope? my material blend mode is masked. and the custom expression node has to connect to the opacity mask.
So, for example when the player looking through the scope, the front end is as wide as the rear of the scope which we are looking through.

У меня есть код нужно его поправить так чтоб данные с сокета считывались в масив длинной 256 символов, а этот массив передавался в функцию parseRequest по заполнению массива или по окончанию передачи из сокета, окончанием передачи следует считать если данные не поступают больше чем 0.3 секунды в функцию должны попадать параметры (массив и длинна переданных данных в массиве) вот мой код
void SockRead()
{
int r;
struct http_request con_d;
struct http_request *req = &con_d;
// Проверка наличия входящих соединений
struct timeval timeout;
timeout.tv_sec = 0.3;

FD_ZERO(&read_fds);
FD_SET(server_socket, &read_fds);
int select_result = select(server_socket + 1, &read_fds, NULL, NULL, &timeout);
if (select_result < 0) {
perror(“Select error”);
return;
}
if (FD_ISSET(server_socket, &read_fds)) {
// Принятие входящего соединения
client_address_length = sizeof(client_address);
client_socket = accept(server_socket, (struct sockaddr *)&client_address, &client_address_length);

return;
}
// Установка неблокирующего режима для сокета клиента
int flags = fcntl(client_socket, F_GETFL, 0);
fcntl(client_socket, F_SETFL, flags | O_NONBLOCK);
тут нужно дописать
// Закрытие соединения с клиентом
close(client_socket);
