These are the requirements:
"The player will pick a target item from a list box showing “!@#$%^&*()_+=?qwertyuiop1234567890” The initial value of score is zero and it must be shown as “0” in the box.
When the player clicks on the “Start Game” button, in every 1 second, three random items will be generated and displayed on the screen (e.g. 3 * 9) at the position as shown above. The three items must not repeat at the same time (i.e. can’t have repeating numbers – e.g. 3 % 3). After starting a game, you can’t change the chosen item.
To play the game, the player must click on the randomly generated item that was chosen earlier to win 5 points. If the player clicks on the wrong item, 3 points are deducted. Therefore, the game score can become negative if the player clicks on many wrong item. For example, if the chosen item is “5” and the randomly generated item are “5”, “a” and “%”, clicking on the 1st item “5” will gain 5 points. Clicking on the item “a” will result in losing 3 points. It is possible to result in a negative score. The current score is displayed on the top right corner of the table. It must be updated in real-time as the player plays the game.
Try to have the font size, foreground and background colours as close as possible to what are shown above.
When the player clicks on the “Stop Game” button, the game is stopped. The screen must remain the same with the chosen item, the current score and the last 3 random items remain unchanged. When you click on “start” game again, it will reset the score to 0 and start the random item generation again. You can also change the chosen item to a new item."

These are the requirements:
“The player will pick a target item from a list box showing “!@#$%^&*()_+=?qwertyuiop1234567890” The initial value of score is zero and it must be shown as “0” in the box.
When the player clicks on the “Start Game” button, in every 1 second, three random items will be generated and displayed on the screen (e.g. 3 * 9) at the position as shown above. The three items must not repeat at the same time (i.e. can’t have repeating numbers – e.g. 3 % 3). After starting a game, you can’t change the chosen item.
To play the game, the player must click on the randomly generated item that was chosen earlier to win 5 points. If the player clicks on the wrong item, 3 points are deducted. Therefore, the game score can become negative if the player clicks on many wrong item. For example, if the chosen item is “5” and the randomly generated item are “5”, “a” and “%”, clicking on the 1st item “5” will gain 5 points. Clicking on the item “a” will result in losing 3 points. It is possible to result in a negative score. The current score is displayed on the top right corner of the table. It must be updated in real-time as the player plays the game.
Try to have the font size, foreground and background colours as close as possible to what are shown above.
When the player clicks on the “Stop Game” button, the game is stopped. The screen must remain the same with the chosen item, the current score and the last 3 random items remain unchanged. When you click on “start” game again, it will reset the score to 0 and start the random item generation again. You can also change the chosen item to a new item.”

Hi, can you contextualize the below text? If possible, please create a process flow. Purpose:
This file includes the risk factors, risks of material misstatement (RoMMs), procedures, and respective guidance as included in the Insurance Contract Liabilities — Premium Allocation Approach (Insurance) Guided Risk Assessment (GRA) included in Omnia (April 2022 Release).
How to Use:
This file is intended to be used as a resource for engagement teams that have not yet transitioned to Omnia. No risk assessment and/or documentation is to be performed within this file.
GRA SET-UP TAB:
"This tab includes general information about the GRA, including:
- Important considerations when completing the GRA.
- Scenarios for which the GRA is not intended.
- Completeness considerations."
ROMMS AND RESPONSE TAB:
"This tab contains all account-specific risk factors, RoMMs, and assertions.
It also includes links to the associated:
- Risk factor group guidance.
- Risk factor guidance.
- Procedures.
- Suggested controls. "
COMMON RISK FACTORS TAB:
This tab contains the common risk factors (e.g., quantitative, process-level risk factors) and the related guidance. All common risk factors are applicable when identifying and assessing all RoMMs.
GUIDANCE TAB:
This tab contains all risk factor group and risk factor guidance. Each guidance item is linked to the applicable risk factor group/risk factor on the "RoMMs and Response" tab.
PROCEDURES TAB:
"The ""Procedures"" tab includes the suggested substantive procedures to address the corresponding suggested RoMM. The procedures associated with deliberative risks may be tailored for engagement-specific circumstances. However, the risk description and procedures are required to be tailored for significant risks. Each of the procedures is linked to the applicable RoMM on the ""RoMMs and Response"" tab.
Where there are multiple procedures suggested to address a RoMM, consider each procedure for applicability and, if applicable, select the suggested procedure. In many cases, the RoMM is appropriately addressed by the combination of audit evidence obtained through the performance of multiple suggested procedures. If the procedure titles within each procedure set begin with either “DW 1” or “DW 2,” teams are to select one of the Deloitte Ways and perform all procedures under that Deloitte Way."
CONTROLS TAB:
This tab contains all suggested controls, which are extracted from the Internal Controls Library. Each of the controls is linked to the applicable RoMM on the "RoMMs and Response" tab.

These are the requirements:
“The player will pick a target item from a list box showing “!@#$%^&*()_+=?qwertyuiop1234567890” The initial value of score is zero and it must be shown as “0” in the box.
When the player clicks on the “Start Game” button, in every 1 second, three random items will be generated and displayed on the screen (e.g. 3 * 9) at the position as shown above. The three items must not repeat at the same time (i.e. can’t have repeating numbers – e.g. 3 % 3). After starting a game, you can’t change the chosen item.
To play the game, the player must click on the randomly generated item that was chosen earlier to win 5 points. If the player clicks on the wrong item, 3 points are deducted. Therefore, the game score can become negative if the player clicks on many wrong item. For example, if the chosen item is “5” and the randomly generated item are “5”, “a” and “%”, clicking on the 1st item “5” will gain 5 points. Clicking on the item “a” will result in losing 3 points. It is possible to result in a negative score. The current score is displayed on the top right corner of the table. It must be updated in real-time as the player plays the game.
Try to have the font size, foreground and background colours as close as possible to what are shown above.
When the player clicks on the “Stop Game” button, the game is stopped. The screen must remain the same with the chosen item, the current score and the last 3 random items remain unchanged. When you click on “start” game again, it will reset the score to 0 and start the random item generation again. You can also change the chosen item to a new item.”
Print the full code after editing according to the requirements without changing the display format of the table. just make the table clickable

Introduction
Recent years have seen rapid advancements in computer vision and natural language processing. Still, many real-world problems are inherently multimodal - they involve several distinct forms of data, such as images and text. Visual-language models face the challenge of combining modalities so that they can open the door to a wide range of applications. Some of the image-to-text tasks that visual language models can tackle include image captioning, image-text retrieval, and visual question answering. Image captioning can aid the visually impaired, create useful product descriptions, identify inappropriate content beyond text, and more. Image-text retrieval can be applied in multimodal search, as well as in applications such as autonomous driving. Visual question-answering can aid in education, enable multimodal chatbots, and assist in various domain-specific information retrieval applications.
Modern computer vision and natural language models have become more capable; however, they have also significantly grown in size compared to their predecessors. While pre-training a single-modality model is resource-consuming and expensive, the cost of end-to-end vision-and-language pre-training has become increasingly prohibitive. BLIP-2 tackles this challenge by introducing a new visual-language pre-training paradigm that can potentially leverage any combination of pre-trained vision encoder and LLM without having to pre-train the whole architecture end to end. This enables achieving state-of-the-art results on multiple visual-language tasks while significantly reducing the number of trainable parameters and pre-training costs. Moreover, this approach paves the way for a multimodal ChatGPT-like model.
What's under the hood in BLIP-2?
BLIP-2 bridges the modality gap between vision and language models by adding a lightweight Querying Transformer (Q-Former) between an off-the-shelf frozen pre-trained image encoder and a frozen large language model. Q-Former is the only trainable part of BLIP-2; both the image encoder and language model remain frozen.
Overview of BLIP-2's framework
Q-Former is a transformer model that consists of two submodules that share the same self-attention layers:
an image transformer that interacts with the frozen image encoder for visual feature extraction
a text transformer that can function as both a text encoder and a text decoder
Q-Former architecture
The image transformer extracts a fixed number of output features from the image encoder, independent of input image resolution, and receives learnable query embeddings as input. The queries can additionally interact with the text through the same self-attention layers.
Q-Former is pre-trained in two stages. In the first stage, the image encoder is frozen, and Q-Former is trained with three losses:
Image-text contrastive loss: pairwise similarity between each query output and text output's CLS token is calculated, and the highest one is picked. Query embeddings and text don't “see” each other.
Image-grounded text generation: queries can attend to each other but not to the text tokens, and text has a causal mask and can attend to all of the queries.
Image-text matching loss: queries and text can see others, and a logit is obtained to indicate whether the text matches the image or not. To obtain negative examples, hard negative mining is used.
In the second pre-training stage, the query embeddings now have the relevant visual information to the text as it has passed through an information bottleneck. These embeddings are now used as a visual prefix to the input to the LLM. This pre-training phase effectively involves an image-ground text generation task using the causal LM loss.
As a visual encoder, BLIP-2 uses ViT, and for an LLM, the paper authors used OPT and Flan T5 models. You can find pre-trained checkpoints for both OPT and Flan T5 on Hugging Face Hub. However, as mentioned before, the introduced pre-training approach allows combining any visual backbone with any LLM.
Using BLIP-2 with Hugging Face Transformers
Using Hugging Face Transformers, you can easily download and run a pre-trained BLIP-2 model on your images. Make sure to use a GPU environment with high RAM if you'd like to follow along with the examples in this blog post.
Let's start by installing Transformers. As this model has been added to Transformers very recently, we need to install Transformers from the source:
pip install git+https://github.com/huggingface/transformers.git
Next, we'll need an input image. Every week The New Yorker runs a cartoon captioning contest among its readers, so let's take one of these cartoons to put BLIP-2 to the test.
import requests
from PIL import Image
url = 'https://media.newyorker.com/cartoons/63dc6847be24a6a76d90eb99/master/w_1160,c_limit/230213_a26611_838.jpg'
image = Image.open(requests.get(url, stream=True).raw).convert('RGB')
display(image.resize((596, 437)))
New Yorker Cartoon
We have an input image. Now we need a pre-trained BLIP-2 model and corresponding preprocessor to prepare the inputs. You can find the list of all available pre-trained checkpoints on Hugging Face Hub. Here, we'll load a BLIP-2 checkpoint that leverages the pre-trained OPT model by Meta AI, which has 2.7 billion parameters.
from transformers import AutoProcessor, Blip2ForConditionalGeneration
import torch
processor = AutoProcessor.from_pretrained("Salesforce/blip2-opt-2.7b")
model = Blip2ForConditionalGeneration.from_pretrained("Salesforce/blip2-opt-2.7b", torch_dtype=torch.float16)
Notice that BLIP-2 is a rare case where you cannot load the model with Auto API (e.g. AutoModelForXXX), and you need to explicitly use Blip2ForConditionalGeneration. However, you can use AutoProcessor to fetch the appropriate processor class - Blip2Processor in this case.
Let's use GPU to make text generation faster:
device = "cuda" if torch.cuda.is_available() else "cpu"
model.to(device)
Image Captioning
Let's find out if BLIP-2 can caption a New Yorker cartoon in a zero-shot manner. To caption an image, we do not have to provide any text prompt to the model, only the preprocessed input image. Without any text prompt, the model will start generating text from the BOS (beginning-of-sequence) token thus creating a caption.
inputs = processor(image, return_tensors="pt").to(device, torch.float16)
generated_ids = model.generate(**inputs, max_new_tokens=20)
generated_text = processor.batch_decode(generated_ids, skip_special_tokens=True)[0].strip()
print(generated_text)
"two cartoon monsters sitting around a campfire"
This is an impressively accurate description for a model that wasn't trained on New Yorker style cartoons!
Prompted image captioning
We can extend image captioning by providing a text prompt, which the model will continue given the image.
prompt = "this is a cartoon of"
inputs = processor(image, text=prompt, return_tensors="pt").to(device, torch.float16)
generated_ids = model.generate(**inputs, max_new_tokens=20)
generated_text = processor.batch_decode(generated_ids, skip_special_tokens=True)[0].strip()
print(generated_text)
"two monsters sitting around a campfire"
prompt = "they look like they are"
inputs = processor(image, text=prompt, return_tensors="pt").to(device, torch.float16)
generated_ids = model.generate(**inputs, max_new_tokens=20)
generated_text = processor.batch_decode(generated_ids, skip_special_tokens=True)[0].strip()
print(generated_text)
"having a good time"
Visual question answering
For visual question answering the prompt has to follow a specific format: "Question: {} Answer:"
prompt = "Question: What is a dinosaur holding? Answer:"
inputs = processor(image, text=prompt, return_tensors="pt").to(device, torch.float16)
generated_ids = model.generate(**inputs, max_new_tokens=10)
generated_text = processor.batch_decode(generated_ids, skip_special_tokens=True)[0].strip()
print(generated_text)
"A torch"
Chat-based prompting
Finally, we can create a ChatGPT-like interface by concatenating each generated response to the conversation. We prompt the model with some text (like "What is a dinosaur holding?"), the model generates an answer for it "a torch"), which we can concatenate to the conversation. Then we do it again, building up the context. However, make sure that the context does not exceed 512 tokens, as this is the context length of the language models used by BLIP-2 (OPT and T5).
context = [
("What is a dinosaur holding?", "a torch"),
("Where are they?", "In the woods.")
]
question = "What for?"
template = "Question: {} Answer: {}."
prompt = " ".join([template.format(context[i][0], context[i][1]) for i in range(len(context))]) + " Question: " + question + " Answer:"
print(prompt)
Question: What is a dinosaur holding? Answer: a torch. Question: Where are they? Answer: In the woods.. Question: What for? Answer:
inputs = processor(image, text=prompt, return_tensors="pt").to(device, torch.float16)
generated_ids = model.generate(**inputs, max_new_tokens=10)
generated_text = processor.batch_decode(generated_ids, skip_special_tokens=True)[0].strip()
print(generated_text)
To light a fire.
Conclusion
BLIP-2 is a zero-shot visual-language model that can be used for multiple image-to-text tasks with image and image and text prompts. It is an effective and efficient approach that can be applied to image understanding in numerous scenarios, especially when examples are scarce.
The model bridges the gap between vision and natural language modalities by adding a transformer between pre-trained models. The new pre-training paradigm allows this model to keep up with the advances in both individual modalities.

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.
As a start, this engine will render a basic spinning box with uniform color. However, it will then expand to cover the full functionality of the game engine. I have created a class structure with the following headers:
BufferUtils.h:

These are the requirements:
"The player will pick a target item from a list box showing “!@#$%^&*()_+=?qwertyuiop1234567890” The initial value of score is zero and it must be shown as “0” in the box.
When the player clicks on the “Start Game” button, in every 1 second, three random items will be generated and displayed on the screen (e.g. 3 * 9) at the position as shown above. The three items must not repeat at the same time (i.e. can’t have repeating numbers – e.g. 3 % 3). After starting a game, you can’t change the chosen item.
To play the game, the player must click on the randomly generated item that was chosen earlier to win 5 points. If the player clicks on the wrong item, 3 points are deducted. Therefore, the game score can become negative if the player clicks on many wrong item. For example, if the chosen item is “5” and the randomly generated item are “5”, “a” and “%”, clicking on the 1st item “5” will gain 5 points. Clicking on the item “a” will result in losing 3 points. It is possible to result in a negative score. The current score is displayed on the top right corner of the table. It must be updated in real-time as the player plays the game.
Try to have the font size, foreground and background colours as close as possible to what are shown above.
When the player clicks on the “Stop Game” button, the game is stopped. The screen must remain the same with the chosen item, the current score and the last 3 random items remain unchanged. When you click on “start” game again, it will reset the score to 0 and start the random item generation again. You can also change the chosen item to a new item."

const item2 = document.getElementById(“item2”);
const item3 = document.getElementById(“item3”);
let score = 0;
let gameInterval = null;
function generateItems() {
const chars = "!@"
These are the requirements:
"The player will pick a target item from a list box showing “!@#$%^&*()_+=?qwertyuiop1234567890” The initial value of score is zero and it must be shown as “0” in the box.
When the player clicks on the “Start Game” button, in every 1 second, three random items will be generated and displayed on the screen (e.g. 3 * 9) at the position as shown above. The three items must not repeat at the same time (i.e. can’t have repeating numbers – e.g. 3 % 3). After starting a game, you can’t change the chosen item.
To play the game, the player must click on the randomly generated item that was chosen earlier to win 5 points. If the player clicks on the wrong item, 3 points are deducted. Therefore, the game score can become negative if the player clicks on many wrong item. For example, if the chosen item is “5” and the randomly generated item are “5”, “a” and “%”, clicking on the 1st item “5” will gain 5 points. Clicking on the item “a” will result in losing 3 points. It is possible to result in a negative score. The current score is displayed on the top right corner of the table. It must be updated in real-time as the player plays the game.
Try to have the font size, foreground and background colours as close as possible to what are shown above.
When the player clicks on the “Stop Game” button, the game is stopped. The screen must remain the same with the chosen item, the current score and the last 3 random items remain unchanged. When you click on “start” game again, it will reset the score to 0 and start the random item generation again. You can also change the chosen item to a new item."
Print the remaining code after editing according to the requirements

This is my current code for ide program. There are 3 classes. test class do not need to be edited.
"public class EWallet {
private String id;
private double balance;
//complete this
public EWallet(String id, double balance) {
}
//complete this
public void deductAmount(double amount) throws InsufficientBalanceException {
}
}
public class InsufficientBalanceException extends Exception {
//complete this class
public double getInsufficientAmount() {
//complete this
return 0;
}
}
public class Test {
public static void main(String[] args) {
try {
EWallet card = new EWallet("A123", 5);
card.deductAmount(10);
System.out.println("Test case failed");
} catch (InsufficientBalanceException ex) {
try {
assert ex.getInsufficientAmount() == 5;
System.out.println("Test case passed");
} catch (AssertionError e) {
System.out.println("Test case failed");
}
}
}
}"
edit the EWallet class and InsufficientBalanceException class according to the following requirements so that when test class is run, the test case passes.
"The EWallet class deductBalance(double amount) method subtract amount from balance.
If there is insufficient balance in the EWallet object for deduction, it will throw InsufficientBalanceException.
Task:
A partial completed skeleton code for EWallet and InsufficientBalanceException are given.
Look through the codes and complete the missing codes.
Hints are given in the codes as comments."

Expand and extend this in a thorough refinement. Utilize classes, edges, variables and the ideas of optimization, recursion, supermodularity, the axiom of constructibility, the principle of charity, intuitionistic logic, polysystems, supersystems, and algorithmics in your refinement, incorporating them comprehensively naturally-flowing way. Also, include a pseudocode representation. I will be asking my professor this at the end of class, today.
"Professor, I'd like to revisit a question I asked earlier, and this time, I've got a more concrete example to illustrate my point. It's about managing indeterminate or undefined values in our programming logic, especially when we're dealing with more complex data types or expressions.
Let's consider a situation where we're dealing with complex integers in our C# program. We know that a complex integer consists of a real part and an imaginary part, like 5 + 3i, for instance. Now, suppose we have a real integer, say 7, and we're supposed to divide this real integer by a complex integer. In mathematical terms, it's not that division by a complex number is undefined, as it is with division by zero, rather it's just not commonly done because it doesn't fit neatly within the system of real numbers. I suppose we could say that it's an indeterminate operation.
My question is, how does C# handle this? I assume it would throw an exception, but how do we, as programmers, maintain a sense of paraconsistency in our logic in such situations?
By paraconsistency, I'm talking about avoiding a logical explosion, where one contradiction suddenly makes everything both true and false, and our logic unravels. It's a term I picked up from philosophical logic, but it feels applicable here too, especially when dealing with more abstract data types or operations that may return indeterminate or undefined results.
In other words, how do we guard against these "in-between" scenarios where an operation isn't clearly true or false? Are we meant to always use try/catch blocks and handle exceptions, or are there other methods or best practices we should be aware of? Are there any non-Boolean solutions to such situations, or is that a concept beyond the scope of C#?
I appreciate your insights on this, as I feel understanding this aspect will help me write more robust and reliable code in the future."

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.
As a start, this engine will render a basic spinning box with uniform color. However, it will then expand to cover the full functionality of the game engine.
I am having some issues with the Renderer class. Here is the code for both the header and the source file:

vkGetPhysicalDeviceQueueFamilyProperties(physicalDevice, &queueFamilyCount, queueFamilies.data());
int i = 0;
for (const auto& queueFamily : queueFamilies)
{
if (queueFamily.queueFlags & VK_QUEUE_GRAPHICS_BIT)
{
indices.graphicsFamily = i;
}
VkBool32 presentSupport = false;
vkGetPhysicalDeviceSurfaceSupportKHR(physicalDevice, i, surface, &presentSupport);
if (presentSupport)
{
indices.presentFamily = i;
}
if (indices.IsComplete())
{
break;
}
i++;
}
return indices;
}
The code seems to get stuck in the EndFrame method in the Renderer class at this line:
vkWaitForFences(device, 1, &inFlightFences[currentFrame], VK_TRUE, UINT64_MAX);
Do you know what the issue could be and how to fix it?

Your task is to create a block-level copy of a disk in Linux that is being actively written to. The destination must be an exact copy. However, once you copy a block, it is possible for the source block to have been updated, and you will need to copy it again to end up with a consistent copy. What tools do you use?

Write a program in C that counts the number of points won in a quiz. A correct answer is marked with 'o', an incorrect answer is marked with 'x', and a skipped question is marked with '-'. Incorrect and skipped answers earn 0 points. A correct answer earns 1 point, and final questions are worth 2 points. In one of the categories, the team can use a joker (the symbol '$') that doubles the points earned in that category. This can only be used once. If this symbol is not used, the points from the last category are doubled. The program should calculate the number of points won by the team, as well as the number of points won at halftime.
I WANT TO:
Input the boundary between questions worth 1 point and questions worth 2 points. The boundary represents the ordinal number of the first question worth 2 points.
Input the team's answer information. Answers for each category are entered in separate rows. In addition to the 'o', 'x', and '-' symbols, a row can also contain the '$' symbol, as well as any number of blank spaces that should be ignored. The total number of categories in the quiz is not known, and should be read from standard input until the end is reached. The '$' symbol can appear more than once, but only its first appearance is counted.
Print the team's answer information for each category in a separate row according to the format shown in the examples.
Calculate and print the number of points earned at halftime and the total number of points in one row according to the format shown in the examples.
Examples:
If I enter this into the program:
4
$ o x - o o x
x o x x o
o o o o - o o
I WANT IT TO OUTPUT THIS:
ox-oox
xoxxo
oooo-oo
