In the picture we have a variable signal (it can be any:
sine wave, square wave, triangle, etc...) included in the Arduino
In a similar reader.
The amplitude and frequency of the signal are variable, one thing we know is that the voltage
The maximum value relative to ground may vary from 1 to 5
to volts, while the signal voltage never goes negative, as far as
The frequency is from 0 to 100 hertz. Our task is to read this through the Arduino
Divide the signal and the given input signal at any moment of time by 2
state: logic high and logic low. logically higher
Consider the input signal if its instantaneous amplitude is greater than or equal to (Vmax +
Vmin)/2, and logical low if it is less than the given image. ours
The task is that when we have a logical high, then we have a voltage of 12 volts
We have to let the voltage from the source into the lamp, and when we have a logical low
The current should no longer flow through the lamp. That is, it is easy to understand that it should be in the lamp
Let's run square wave 12 volt pulses depending on the input signal. also
The picture shows the screen on which we should output the input signal
frequency and maximum voltage to ground.
Also worth noting is the fact that the signal may be in some period of time
Let it be, for example, a sinusoid with a frequency of 5 Hz, and the voltage should vary from Vmin=2
Vmax=3 volts to ground and at this time, it should be displayed
Image: 3 volts, 5 hertz. And after some time it becomes sinusoidal
The signal may be replaced by a rectangular signal that oscillates Vmin=1-
from Vmax=5 volts, and the frequency will be 20 hertz, and at this time the screen
The values should be changed accordingly. corresponding to the input signal
Data changes should be updated on the screen every 5 seconds.
Create a Proteus circuit using the components in the picture
in the simulator and write the code for Arduino.

Давай начнем с самого простого. В этом упражнении тебе необходимо получить отфильтрованные данные из таблицы
в базе данных. Почему важно фильтровать данные именно в запросе, а не после этого в библиотеке Pandas?
Потому что таблицы могут иметь огромный размер. Если ты попыташься получить всю таблицу, то не сможешь ее "переварить"
– у тебя может не хватить оперативной памяти. Всегда помни об этом.
Первый способ фильтрации — выбрать только те столбцы, которые тебе действительно нужны.
Второй способ — выбрать только те строки, которые тебе действительно нужны.
Подробное описание задания:
Помести базу данных в подкаталог data в корневом каталоге, используемом в рамках этого проекта.
Создай соединение с базой данных с помощью библиотеки .sqlite3
Получи схему таблицы с помощью и запроса .pageviewspd.io.sql.read_sqlPRAGMA table_info(pageviews);
Получи только первые строк таблицы , чтобы проверить, как она выглядит.10pageviews
Получи подтаблицу с помощью только одного запроса, в котором:
используются только и uiddatetime;
используются только данные пользователей (), и не используются данные администраторов;user_*
сортировка выполняется по в порядке возрастания;uid
столбец индекса — это datetime;
datetime преобразован в DatetimeIndex;
имя датафрейма — .pageviews
Закрой соединение с базой данных.

В этом упражнении ты создашь так называемую витрину данных. Она представляет собой таблицу,
которую можно использовать для аналитических целей. Обычно она создается путем объединения нескольких отдельных таблиц.
В этом упражнении мы будем собирать различные данные о наших пользователях: когда они сделали свои первые коммиты,
когда они впервые посетили ленту новостей и т. д. Это поможет позднее выполнить анализ данных.
Что тебе нужно сделать в этом упражнении (ознакомься с полным описанием задания):
Создай соединение с базой данных с помощью библиотеки .sqlite3
Создай новую таблицу в базе данных, объединив таблицы и с помощью только одного запроса.
datamartpageviewschecker
Таблица должна содержать следующие столбцы: , , , .uidlabnamefirst_commit_tsfirst_view_ts
first_commit_ts — это просто новое имя для столбца из таблицы ; он показывает первый коммит конкретного лабораторного задания конкретного пользователя.timestampchecker
first_view_ts — первое посещение пользователем из таблицы , метка времени посещения пользователем ленты новостей.pageviews
По-прежнему нужно использовать фильтр .status = 'ready'
По-прежнему нужно использовать фильтр .numTrials = 1
Имена лабораторных заданий по-прежнему должны быть из следующего списка: , , , , , .laba04laba04slaba05laba06laba06sproject1
Таблица должна содержать только пользователей ( с ), а не администраторов.uiduser_*
first_commit_ts и должны быть распарсены как .first_view_tsdatetime64[ns]
Используя методы библиотеки Pandas, создай два датафрейма: и . testcontrol
test должен включать пользователей, у которых имеются значения в .first_view_ts
control должен включать пользователей, у которых отсутствуют значения в .first_view_ts
Замени пропущенные значения в средним значением пользователей из (оно пригодится нам для анализа в будущем).controlfirst_view_tstest
Сохрани обе таблицы в базе данных (вы будете использовать их в следующих упражнениях).
Закрой соединение.
Небольшой совет — выполняй все операции поочередно, от простой к более сложной, а не пытаясь сделать всё вместе и сразу. Это поможет в отладке твоих запросов.

#1. Помещаем базу данных checking-logs.sqlite в подкаталог data в корневом каталоге:
import shutil
# Копирование базы данных в подкаталог data
shutil.copyfile('C:/Users/lpoti/Documents/DS_21/DS10-1-develop/datasets/checking-logs.sqlite', 'C:/Users/lpoti/Documents/DS_21/DS10-1-develop/datasets/data/checking-logs.sqlite')
#2. Создаем соединение с базой данных с помощью библиотеки sqlite3:
import sqlite3
# Создание соединения с базой данных
conn = sqlite3.connect('C:/Users/lpoti/Documents/DS_21/DS10-1-develop/datasets/data/checking-logs.sqlite')
#3. Получаем схему таблицы pageviews с помощью функции read_sql и запроса PRAGMA table_info:
import pandas.io.sql as pd_sql
# Получение схемы таблицы pageviews
schema_query = "PRAGMA table_info(pageviews);"
schema = pd_sql.read_sql(schema_query, conn)
print(schema)
#4. Получаем только первые 10 строк таблицы pageviews:
# Получение первых 10 строк таблицы pageviews
query = "SELECT * FROM pageviews LIMIT 10;"
pageviews = pd_sql.read_sql(query, conn)
print(pageviews)
#5. Получаем подтаблицу pageviews с помощью запроса, который отбирает данные пользователей, сортирует их по идентификатору пользователя (uid) в порядке возрастания и преобразует столбец datetime в индекс типа DatetimeIndex:
# Получение подтаблицы pageviews с отбором данных по пользователям и сортировкой по uid
query = """
SELECT datetime, uid
FROM pageviews
WHERE uid LIKE 'user_%'
ORDER BY uid ASC;
"""
# Чтение подтаблицы из базы данных и подгонка типов столбцов
pageviews = pd_sql.read_sql(query, conn, parse_dates=['datetime'], index_col='datetime')
print(pageviews)
#6. Закрываем соединение с базой данных:
# Закрытие соединения с базой данных

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:

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:

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:

I am getting an error coming through the Vulkan validation layers:

The Vulkan spec states: buffer must not have been bound to a memory object (https://vulkan.lunarg.com/doc/view/1.3.239.0/windows/1.3-extensions/vkspec.html#VUID-vkBindBufferMemory-buffer-07459)

[1] 0xab64de0000000020, type: 9, name: NULL
[2] 0xc4f3070000000021, type: 8, name: NULL
This error seems to occur in the Texture::LoadFromFile method at line:
vkBindBufferMemory(device, stagingBuffer, stagingBufferMemory, 0);
What does it mean and how do I fix it?

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:

The Vulkan spec states: buffer must not have been bound to a memory object (https://vulkan.lunarg.com/doc/view/1.3.239.0/windows/1.3-extensions/vkspec.html#VUID-vkBindBufferMemory-buffer-07459)

This error seems to occur in the Texture::LoadFromFile method at line:
vkBindBufferMemory(device, stagingBuffer, stagingBufferMemory, 0);
What does it mean and how do I fix it?

To make the code send requests from different IP addresses, you can use proxy servers. You can set up a proxy server in the Playwright library with the following steps:
1. Install some proxy libraries if you haven’t already:
pip install proxybroker
2. You will need a list of proxy servers. You can obtain a list of proxy servers using the ‘proxybroker’ library. To find and collect a list of working proxies, use the following code snippet:
import asyncio
from proxybroker import Broker
async def show(proxies):
while True:
proxy = await proxies.get()
if proxy is None:
break
print(‘Found proxy: %s’ % proxy)
proxies = asyncio.Queue()
broker = Broker(proxies)
# Collect 10 working HTTP(S) proxies
tasks = asyncio.gather(broker.find(types=[‘HTTP’, ‘HTTPS’], limit=10))
if asyncio.run_until_complete(tasks):
print(‘Done.’)
This will provide you with a list of working proxies, store them in a list for using in your playwright code.
3. Update your main method to use the proxies while making requests with Playwright:
from random import choice
async def main():
# Add the list of proxies collected with proxybroker
proxy_list = [
# Format: ‘http://username:password@proxy_ip:proxy_port’
‘http://username:password@proxy_ip:proxy_port’,
‘http://username:password@proxy_ip:proxy_port’,
# Add more proxies as needed
]
while True:
# Randomly choose a proxy for each token_symbol
for token_symbol in token_symbols:
proxy = choice(proxy_list)
result = await get_token_info(token_symbol, proxy)
print(result)
await asyncio.sleep(60)
# Modify your get_token_info function to accept a proxy parameter
async def get_token_info(token_symbol, proxy):
# Existing code …
async with async_playwright() as p:
browser = await p.chromium.launch(headless=True, proxy={“server”: proxy})
# Rest of the existing code …
These steps will ensure that the requests are sent using different IP addresses. Note that using free or public proxies can be unreliable and might affect the performance of your script. It’s recommended to use a reliable proxy service or your own proxy servers.
In conclusion, here’s the complete code with the integration of proxy:
import asyncio
from bs4 import BeautifulSoup
from random import choice
from playwright.async_api import async_playwright
async def get_token_info(token_symbol, proxy):
async with async_playwright() as p:
browser = await p.chromium.launch(headless=True, proxy={“server”: proxy})
# Rest of the existing code…
# Add the list of proxies collected with proxybroker
proxy_list = [
# Format: ‘http://username:password@proxy_ip:proxy_port’
‘http://username:password@proxy_ip:proxy_port’,
‘http://username:password@proxy_ip:proxy_port’,
# Add more proxies as needed
]
async def main():
while True:
# Randomly choose a proxy for each token_symbol
for token_symbol in token_symbols:
proxy = choice(proxy_list)
result = await get_token_info(token_symbol, proxy)
print(result)
await asyncio.sleep(60)
token_symbols = [
“0x0E481Fa712201f61dAf97017138Efaa69e2A3df3”,
“0x2023aa62A7570fFd59F13fdE2Cac0527D45abF91”,
“0x2222222222222222222222222222222222222222”,
“0x0d4890ecEc59cd55D640d36f7acc6F7F512Fdb6e”]
asyncio.run(main())
The above code allows you to send requests from different ip addresses. will this be enough to parse the site, will they block ip addresses?
If that's not enough, please suggest a better way.

The provided code will help in sending requests from different IP addresses. However, there is no guarantee that the target website will not block the IP addresses provided by the proxies.
To increase the chances of successful scraping and avoid IP blocking, consider the following best practices:
1. Implement rate limiting: Insert a random delay between requests to reduce the rate at which you are sending requests to the website. You can use the time.sleep() function along with a random interval. For example:
import time
from random import randint
time.sleep(randint(2, 10))
2. Use a rotating proxy service: Instead of using a static list of proxies, consider using a rotating proxy service that provides a large number of proxy servers and rotates them automatically.
3. Respect the website’s robots.txt file: Be sure to check the target website’s robots.txt file to ensure that you are allowed to scrape the required data.
4. Spoof user-agent strings: Websites might block requests that come from automated user-agents. Make your requests appear more human-like by using random user-agent strings.
from playwright.async_api import async_playwright
from fake_useragent import UserAgent
ua = UserAgent()
async def get_token_info(token_symbol, proxy):
async with async_playwright() as p:
browser = await p.chromium.launch(
headless=True,
proxy={“server”: proxy},
user_agent=ua.random,
)
# Rest of the existing code…
By combining these best practices with the provided code, you can significantly improve your chances of successful scraping without getting blocked by the target website. Nevertheless, it’s essential to comply with the website’s terms and conditions and ensure that you’re using compliant web scraping practices.

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:

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:

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:

It seems to occur when calling vkUpdateDescriptorSets in the Material::CreateDescriptorSet method. How can I alter the code to fix this issue?

These methods should also remain in it.
1. random_delay() function is added for rate limiting.
2. The proxy parameter in the get_token_info function accepts a rotating proxy service URL.
3. The can_scrape() function is added to respect the website's robots.txt file.
4. The fake_useragent library is utilized to spoof random user-agent strings during browser launch.

These are the requirements:
“On completion of this assignment a student should be able to write a Java application
that:
• Makes use of Java API “Swing” and “AWT” packages
• Handles generated events
• Makes use of layout manager to organize the GUI components
• Know how to apply and design a program using object-oriented concepts
2. Task
Enhance the one player Java game application “HighSum” done in Assignment 1 with Graphical User Interface (GUI).
2.1 Login
The game starts by the player logging into the game.
2.2 Play Game
The game starts after the player click on “Login”.
First, the dealer will shuffles the deck.
(You may include animation in this frame to simulate “shuffle” effect as enhancement.)
Then the dealer deals two cards from the top of the deck to the player and itself.
Since the player’s last card is higher than the dealer’s last card, the player gets to Call the game.
Assume the player states 10 as the bet chips.
The player’s chip will be deducted by 10.
The chips on table will be updated to 20 and the dealer deals cards for next round.
Assume the dealer’s last card is higher than the player’s last card.
The dealer Call the game and the player gets to choose to Follow or Quit the game.
If the player follows the game, 10 chips will be deducted from the player’s balance chips.
(Asumme the dealer place 10 chips.)
The games carry on for maximum of four rounds.
In the last round, the player with the highest total sum wins the game.
And the game continues until the player exits the game.
Error Handling
Your program should be able to handle error situations like where a player enter wrong password or has insufficient chips.
You should look out for other possible exceptions and handle them too.”
Edit the code so that when highsum gui is run,
The game runs on the GUI and NOT on the console. The gui currently is empty and blank and cannot be closed when run.

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.

These are the requirements:
“On completion of this assignment a student should be able to write a Java application
that:
• Makes use of Java API “Swing” and “AWT” packages
• Handles generated events
• Makes use of layout manager to organize the GUI components
• Know how to apply and design a program using object-oriented concepts
2. Task
Enhance the one player Java game application “HighSum” done in Assignment 1 with Graphical User Interface (GUI).
2.1 Login
The game starts by the player logging into the game.
2.2 Play Game
The game starts after the player click on “Login”.
First, the dealer will shuffles the deck.
(You may include animation in this frame to simulate “shuffle” effect as enhancement.)
Then the dealer deals two cards from the top of the deck to the player and itself.
Since the player’s last card is higher than the dealer’s last card, the player gets to Call the game.
Assume the player states 10 as the bet chips.
The player’s chip will be deducted by 10.
The chips on table will be updated to 20 and the dealer deals cards for next round.
Assume the dealer’s last card is higher than the player’s last card.
The dealer Call the game and the player gets to choose to Follow or Quit the game.
If the player follows the game, 10 chips will be deducted from the player’s balance chips.
(Asumme the dealer place 10 chips.)
The games carry on for maximum of four rounds.
In the last round, the player with the highest total sum wins the game.
And the game continues until the player exits the game.
Error Handling
Your program should be able to handle error situations like where a player enter wrong password or has insufficient chips.
You should look out for other possible exceptions and handle them too.”
Edit the code so that when highsum gui is run,
The game runs on the highsumGUI and NOT on the console. The gui currently is empty and blank and cannot be closed when run.

These are the requirements:
"On completion of this assignment a student should be able to write a Java application
that:
• Makes use of Java API "Swing" and "AWT" packages
• Handles generated events
• Makes use of layout manager to organize the GUI components
• Know how to apply and design a program using object-oriented concepts
2. Task
Enhance the one player Java game application "HighSum" done in Assignment 1 with Graphical User Interface (GUI).
2.1 Login
The game starts by the player logging into the game.
2.2 Play Game
The game starts after the player click on “Login”.
First, the dealer will shuffles the deck.
(You may include animation in this frame to simulate “shuffle” effect as enhancement.)
Then the dealer deals two cards from the top of the deck to the player and itself.
Since the player’s last card is higher than the dealer’s last card, the player gets to Call the game.
Assume the player states 10 as the bet chips.
The player’s chip will be deducted by 10.
The chips on table will be updated to 20 and the dealer deals cards for next round.
Assume the dealer’s last card is higher than the player’s last card.
The dealer Call the game and the player gets to choose to Follow or Quit the game.
If the player follows the game, 10 chips will be deducted from the player’s balance chips.
(Asumme the dealer place 10 chips.)
The games carry on for maximum of four rounds.
In the last round, the player with the highest total sum wins the game.
And the game continues until the player exits the game.
Error Handling
Your program should be able to handle error situations like where a player enter wrong password or has insufficient chips.
You should look out for other possible exceptions and handle them too."
Edit the code so that when highsum gui is run,
There is an error : "Description Resource Path Location Type
The type GameTableFrame is already defined HighSumGUI.java /A3Skeleton/src/GUIExample Unknown Java Problem

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:

These are the requirements:
"On completion of this assignment a student should be able to write a Java application
that:
• Makes use of Java API "Swing" and "AWT" packages
• Handles generated events
• Makes use of layout manager to organize the GUI components
• Know how to apply and design a program using object-oriented concepts
2. Task
Enhance the one player Java game application "HighSum" done in Assignment 1 with Graphical User Interface (GUI).
2.1 Login
The game starts by the player logging into the game.
2.2 Play Game
The game starts after the player click on “Login”.
First, the dealer will shuffles the deck.
(You may include animation in this frame to simulate “shuffle” effect as enhancement.)
Then the dealer deals two cards from the top of the deck to the player and itself.
Since the player’s last card is higher than the dealer’s last card, the player gets to Call the game.
Assume the player states 10 as the bet chips.
The player’s chip will be deducted by 10.
The chips on table will be updated to 20 and the dealer deals cards for next round.
Assume the dealer’s last card is higher than the player’s last card.
The dealer Call the game and the player gets to choose to Follow or Quit the game.
If the player follows the game, 10 chips will be deducted from the player’s balance chips.
(Asumme the dealer place 10 chips.)
The games carry on for maximum of four rounds.
In the last round, the player with the highest total sum wins the game.
And the game continues until the player exits the game.
Error Handling
Your program should be able to handle error situations like where a player enter wrong password or has insufficient chips.
You should look out for other possible exceptions and handle them too."
There is an error in the code "Description Resource Path Location Type
The constructor GameTableFrame(HighSum) is undefined HighSumGUI.java /A3Skeleton/src/GUIExample line 29 Java Problem

} and i have this reduxToolkit fn import {createSlice, createAsyncThunk} from '@reduxjs/toolkit';
import AsyncStorage from '@react-native-async-storage/async-storage';
import ReclamationService from '@services/features/reclamation.services';
const initialState = {
reclamations: [],
};
export const getReclamations = createAsyncThunk(
'reclamation/getReclamations',
async ({accessToken}, thunkAPI) => {
try {
const response = await ReclamationService.getReclamation(accessToken);
console.log(
'response from redux =====>',
response?.data?.[0]?.reclamations,
);
response === undefined || response === null
? thunkAPI.dispatch(
setMessagePassword(
'Erreur de connexion veuillez, ressayer plus tard',
),
) && thunkAPI.rejectWithValue()
: thunkAPI.dispatch(setMessagePassword(response?.message)) &&
console.log('response.data', response.message);
if (response) {
return {
reclamations: response?.data?.[0]?.reclamations || [],
// any other fields to include in the payload, if necessary
};
}
console.log('reclamations', reclamations);
} catch (error) {
console.log('error redux', error.response.data);
thunkAPI.dispatch(setMessageRegister(response.message));
setMessageRegister(error.response.message);
thunkAPI.rejectWithValue(error.response.data);
}
},
);
const reclamationReducer = createSlice({
name: 'reclamation',
initialState,
reducers: {},
extraReducers: builder => {
builder
.addCase(getReclamations.fulfilled, (state, action) => {
console.log(
'redux======================================>',
action.payload.reclamations,
);
state.reclamations = action.payload.reclamations;
})
.addCase(getReclamations.rejected, (state, action) => {
state.reclamations = [];
});
},
});
const {actions} = reclamationReducer;
export default reclamationReducer.reducer;
and the scrren when i disptach the redux
const getReclamationOfUser = () => {
console.log('inside fn 1');
setLoading(true);
console.log('inside fn 2');
console.log('token', accessToken);
dispatch(getReclamations({accessToken}))
.unwrap()
.then(() => {
console.log('inside fn 3');
setLoading(false);
})
.catch(error => {
console.log('inside fn error', error);
setLoading(false);
});
};
useEffect(() => {
getReclamationOfUser();
}, []);
useEffect(() => {
setReclamation(reclamations);
console.log('rec', reclamation);
}, [reclamations]); so now correct this code to get the response.data witch is an array and set the value of reclamations to the response.data
