To avoid too long lines, you can do the following.
Instead of:
```
with open(filename, 'wb') as file, request.urlopen(image.url) as response:
pass
```
I, do for example:
```
f = lambda: open(filename, 'wb')
r = lambda: request.urlopen(image.url)
with r() as response, f() as file:
pass

Why is it that when I inject `ILogger<MyClassName>` and call `Logger.LogInformation` I don't see that in Application Insights, but when I call `Logger.LogError` I do?
Here is my code
```c#
public async ValueTask DeleteMessageAsync(string chatId, int messageId)
{
Logger.LogInformation(
"Deleting message: {chatId} {messageId}",
chatId,
messageId);
try
{
await TelegramBotClient.DeleteMessageAsync(chatId, messageId);
}
catch (ApiRequestException ex)
when (ex.ErrorCode == (int)HttpStatusCode.BadRequest)
{
Logger.LogError(ex, "Could not Delete message");
}
}
```
Here is the logging section of my `host.json` file
```json
"logging": {
"applicationInsights": {
"samplingSettings": {
"isEnabled": true,
"excludedTypes": "Request"
},
"enableLiveMetricsFilters": true
},
"DurableTask.AzureStorage": "Information",
"DurableTask.Core": "Information"
}
```
Here is the host builder for my Azure functions app
```c#
IHost host = new HostBuilder()
.AddServiceDefaults(useOtlpExporter: false, isDevelopment: true)
.ConfigureFunctionsWorkerDefaults()
.ConfigureServices(services =>
{
services.AddApplicationInsightsTelemetryWorkerService();
services.ConfigureFunctionsApplicationInsights();
services.AddSingleton<ITelegramBroadcastService, TelegramBroadcastService>();
services.AddSingleton<IAuthorizationService, AuthorizationService>();
services.AddDurableTaskClient(x =>
{
});
services.AddAzureClients(clientBuilder =>
{
clientBuilder.AddBlobServiceClient(Environment.GetEnvironmentVariable("AzureWebJobsStorage"));
});
})
.ConfigureAppConfiguration((context, config) =>
{

host.Run();

A repository can have any number of image tags. There is no stated limit for size. In practice, if an image layer gets much larger than 10 or 20 gigabytes, you may experience problems with push and pull. Your mileage may vary.
There is no limit for builds or tags for public images. (This can be changed over a period of time)
As long as you wanted to play around docker public repository will do. But, if you are looking for a private repository I would recommend hosting your own binary repository managers JFfrog or Nexus to maintain all kinds of artifacts including docker images.
Source: https://forums.docker.com/t/does-docker-hub-have-a-size-limitation-on-repos-or-images/10154
**UPDATE 2**
Inactive images are defined as images that have not been pulled or pushed in 6 months. Starting November 1, 2020:
1. Free accounts may retain inactive images for up to 6 months
2. Anonymous users will have an upper limit of 100 image pulls in a six hour period
3. Authenticated users will have an upper limit of 200 image pulls in a six hour period
A pull is defined as up to two GET requests to the registry URL path β/v2/*/manifests/*β.
**PS:** It is all about the policies set by the Docker, Inc. It can change over time. |

I wrote a small `struct` used to sort dependencies between projects (it could be used to sort anything really, the interface used is just a `std::string`) in a container/solution.
The dependencies are defined and fed from a json object (parsing is done using `boost::json`).
Example dependencies:
"container_dependency_tree": {
"abc": ["def","hello","world"],
"def": ["xyz","x","y"],
"xyz": [],
},
Header:
#pragma once
#include <boost/json.hpp>
#include <map>
#include <string>
#include <vector>
#include <set>
namespace tmake {
struct container_dependency_tree_t {
private:
std::map<std::string, std::vector<std::string>>
m_flat;
bool
m_compare(const std::string& lhs, const std::string& rhs) const;//returns true if lhs depends on rhs
std::set<std::string, decltype(&m_compare)>
m_sorted = decltype(m_sorted)(&container_dependency_tree_t::m_compare);
public:
container_dependency_tree_t() {}
container_dependency_tree_t(const boost::json::object& container_dependency_tree);
public:
const decltype(m_flat)&
flat() const;
const decltype(m_sorted)&
sorted() const;
};
}
Implementation:
#include <tmake/container_dependency_tree_t.h>
namespace tmake {
container_dependency_tree_t::container_dependency_tree_t(const boost::json::object& container_dependency_tree) {
for (const auto& kv : container_dependency_tree) {
std::vector<std::string> dependencies;
const boost::json::array& dd = kv.value().as_array();
for (const auto& d : dd) {
dependencies.push_back(d.as_string().c_str());
}
m_flat.emplace(kv.key(), dependencies);
}
for (const auto& f : m_flat) {
m_sorted.insert(f.first);//***ISSUE HERE***
}
}
bool container_dependency_tree_t::m_compare(const std::string& lhs, const std::string& rhs) const {
auto find = m_flat.find(lhs);
if (find == m_flat.end())
return false;
for (const auto& dependency : find->second) {
if (rhs == dependency || m_compare(dependency, rhs)) {
return true;
}
}
return false;
}
const decltype(container_dependency_tree_t::m_flat)& container_dependency_tree_t::flat() const {
return m_flat;
}
const decltype(container_dependency_tree_t::m_sorted)& container_dependency_tree_t::sorted() const {
return m_sorted;
}
}
The issue is with the instruction `m_sorted.insert(f.first);`.
I get thrown some compiler mumbo-jumbo that I dont understand - the error is somewhere within the STL implementation files (MSVC xutility(1372,19): error C2064: le terme ne correspond pas Γ une fonction qui prend 2 arguments).

It is recommended to rewrite the DTO with a constructor applying the required parameters. If rewriting is not possible, implement a custom denormalization tool. Following approach ensures strict validation during deserialization.
final class SimpleDtoDenormalizer implements DenormalizerInterface
{
public function denormalize(mixed $data, string $type, ?string $format = null, array $context = []): mixed
{
if (!is_array($data)) {
throw new \InvalidArgumentException('Expected an array, got ' . get_debug_type($data));
}
$dto = new SimpleDto();
$dto->name = $data['name'] ?? throw new \InvalidArgumentException('Missing "name"');
$dto->value = $data['value'] ?? throw new \InvalidArgumentException('Missing "value"');
return $dto;
}

I'm trying to publish to the local repository but to set the artifact name explicitly.
For example, say the org is "quick.fox" and the module is "core" with version being 1.1.
What I get is:
```<repo>/quick.fox/core/1.1/core-1.1.jar```
What I'd like it to be:
```<repo>/quick.fox/core/1.1/prefix-core.jar```
a basic sample code would be:
```
apply plugin: 'maven-publish'
publishing {
publications {
maven(MavenPublication) {
group = "quick.fox"
artifactId = "core"
version = "1.1"
}
}
}
```
How would I do that? I'm using Gradle 6.5.1, and I am open to using either the maven or ivy publish plugins.

It appears that it's important to express that you want the 7 specific items extracted by calling for tokens=1-7.
Token 1 will be %%G, with each successive, stipulated token using %%H, %%I, etc.
Wanting to express one line for each token comes by echoing them 1 echo command at a time for each token's variable, either as one per line stacked or parenthetically grouped sequentially with &s:
do (echo %%G) & (echo %%H) & (echo %%I)... etc
In total, the following worked for me:
`for /f "tokens=1-7" %G in ("1 2 7 16 21 26 688") do (
echo %G
echo %H
echo %I
echo %J
echo %K
echo %L
echo %M
)` |

The program is placing the files to the path `Users/username/` instead of the `Oil and Cells folder`. Can I fix this issue with the compiling command?
I used `gfortran -o Planar_Surfactant Planar_Surfactant.f` while inside of the `Oil and Cells` folder to compile the executable.
`~ % /Users/username/Documents/BMEN\ Research/Oil\ And\ Cells/Planar_Surfactant ; exit;`
this is what shows up when I run the program along with some information about the base values.
I'm pretty new to fortran coding so I'm not quite sure what to try or how to resolve this issue. |
My journey through creating a PDF form (upgrading old Zend PDF library to be able to do it) continues.
I am struggling with checkbox and radio buttons, trying to get them displayed consistently. I did follow several guides and tips here and still there are differences in getting the button displayed in Chrome, Mozilla and Acrobat reader.
It seems no matter what I do, Acrobat reader ignores defines content stream and replaces it with it's own for checked and unchecked state of the button. Strangely enough, it displays the defined stream when the checked button has focus. So when I set in the stream I want the checkbox to display let's say a cross (either through ZaDb character or just simply two crossed lines), Acrobat reader only displays the cross when I click and check the button. As soon as I click elsewhere, the cross is replaced with the default check mark.
(Mozilla completely ignores any settings and just always displays their own icons so at least the user doesn't se two sets of icons.)
So is there any way how I can force Acrobat reader to show the set stream content? Or is there a way to set the stream content exactly the same as the default acrobat reader? I have no problem using the default check mark but I can't get the position right with possibly dynamic size of the checkbox.
Here is my source code with checkbox:

i am trying speed up my implementation of rolling zscore.
What I'm doing: I've a matrix features (nxm). And each column of features I wanna apply a rolling window that are different from one column to the other.
So right now, i 'm doing:
- for each row >= maximum rollong window
- for each column of feature
- get the vector from i - rolling window to i
- compute mean, std, zscore
What i've done:
#include <Eigen/Dense>
using namespace std;
using namespace Eigen;
double computeMean(const VectorXf &v)
{
double sum = 0;
for ( auto e : v) { sum += e; }
return sum / v.rows();
}
double computeStdDeviation(const VectorXf &v, double mean)
{
double varianceSum = 0;
for ( auto x : v) { varianceSum += ( x - mean) * ( x - mean); }
double variance = varianceSum / v.rows();
return sqrt(variance);
}
double zScore(double x, double stdDev, double mean)
{
if (stdDev > 0) return (x - mean) / stdDev;
return -5;
}
MatrixXf NormalizeData(const MatrixXf& features, const vector<int> shifts) {
int max = *max_element(shifts.begin(), shifts.end());
MatrixXf df(features.rows() - max, features.cols());
for (size_t i = max; i < features.rows(); ++i) {
for (size_t j = 0; j < features.cols(); ++j) {
VectorXf vec = features(seq(i-shifts[j]+1,i), j); // get a vector of size shifts[j]
double elem = vec(last);
double mean = computeMean(vec);
double std = computeStdDeviation(vec, mean);
df(i-max, j) = zScore(elem , std, mean);
}
}
return df;
}
shifts being a vector [10, 20, 30, ...]
But even with as low as 500k rows, this takes a very long time.
Any one has an idea on how to speed this up please?
Update:
I tried
std::for_each(std::execution::par, features.rowwise().begin()+max-1, features.rowwise().end(), [] (auto&& row) {
int index = row.index - max + 1;
if (index % 100000 == 0) std::cout << "NormalizeData Filename: " << filename << " - " << index << " / " << df.rows() << endl;
df(index, 0) = row(0);
for (size_t j = 0; j < shifts.size(); ++j) {
...}}
But it says "max" is not captured,
"df" is not captured
"shifts" is not captured... |
I had the same issue in one of my projects. I discovered that in the build process, cx_Freeze was taking all the packages installed in the computer, so I sat up a virtual-environment on the root directory of the project to install there only the packages needed for my project, once this was done cx_Freeze chose only the packages in the venv, and the error disappeared.
I found about this in the common error section of the cx_Freeze documentation: https://cx-freeze.readthedocs.io/en/latest/faq.html
Have a nice day.

add this on top of your controller:
```php
/**
*
* @OA\Info(
* version="1.0.0",
* title="Organization",
* description="test description",
* @OA\Contact(
* name="test",
* email="test@test"
* ),
* ),
* @OA\Server(
* url="/api/v1",
* ),
*/
class YourController extends Controller
```
then you have to set like this documentation for all of your controller method.
suggestion:
if you using PHP 8.1 or higher
Laravel 8.x or higher
instead of using `L5-Swagger` use `dedoc/scamble` it will generate document automatically for you and it's on top of swagger

When a user right-clicks and drags a file into a different directory, they are presented with a small context menu that includes entries such as **Copy here** and **Move here**:
Is there a way to query these menu items yourself?
I was able to trigger the default implementation for this right drag-and-drop popup by following these steps:
- Register your app with `RegisterDragDrop`.
- In the `IDropTarget::Drop` method:
- Obtain the `IShellFolder` interface for the drop path.
- Get the `IDropTarget` interface from this folder.
- Forward the `IDataObject` to the `DragEnter` and `Drop` methods.
- The `Drop` method will display the correct context menu.
Here's the simplified version of the code:
```
HRESULT Win_DragDropTargetDrop(IDropTarget *iTarget, IDataObject *iData, DWORD keys, POINTL cursor, DWORD *effect)
{
HRESULT hr = 0;
IShellFolder *folder = null;
IDropTarget *folderDropTarget = null;
POINTL pt = {0};
hr = Win_GetIShellFolder(hwnd, dragDropPath, &folder);
hr = folder->lpVtbl->CreateViewObject(folder, hwnd, &IID_IDropTarget, &folderDropTarget);
hr = folderDropTarget->lpVtbl->DragEnter(folderDropTarget, iData, MK_RBUTTON, pt, effect);
hr = folderDropTarget->lpVtbl->Drop(folderDropTarget, iData, MK_RBUTTON, pt, effect);
}
```
However, what I want is to enumerate these items within `IContextMenu` myself, using functions such as `CreatePopupMenu`, `QueryContextMenu`, and then iterating through that menu via `GetMenuItemCount` and `GetMenuItemInfo`.
The reason is that I'm rendering the context menu myself (instead of using the Windows built-in UI framework). I'm already doing this for the regular right-click context menu on a directory background.

in the application I made using this library [react-native-tcp-socket](https://github.com/Rapsssito/react-native-tcp-socket), the server is created and the functions in the listen event work, but server.on('connection',() => {}) does not work
**Server.js**
```
import TcpSocket from 'react-native-tcp-socket';
import NetInfo from '@react-native-community/netinfo';
export const server = new TcpSocket.Server();
export let address = null;
const getWifi = async () => {
try {
const state = await NetInfo.fetch();
if (state.isConnected) {
const netInfo = state;
const newIpAddress = netInfo.details && netInfo.details.ipAddress;
return newIpAddress;
}
} catch (error) {
console.log(error);
}
};
export const closeServer = () => {
if (server) {
console.log(`server closed`);
server.close();
} else {
console.log('server not found');
}
};
export const init = async () => {
const ip = await getWifi();
server.on('connection', socket => {
socket.on('data', () => {
socket.write('Echo server\r\n');
});
});
server.listen({port: 0, host: `127.0.0.1`, reuseAddress: true}, () => {
const port = server.address()?.port;
if (!port) throw new Error('Server port not found');
address = server.address();
console.log(address);
});
};
```
**Client.js**
```

In this method, it should write the address of the socket when there is a connection or log when there is data coming in, but it is not working, can you help me what I might be doing wrong?
thanks in advance

I am new to hadoop.
So, I am assuming and it seems obvious that hadoop will have to keep track of the free space in each datanode.
For the reason being, if new file saving request comes to hadoop, hadoop system will have to decide which datanodes to choose to store the incoming file.
Now, each datanode keeps the data in location given by config : dfs.datanode.data.dir.
So I can set any directory location in this config.
Let us assume I set, D:/data/hadoop
Now how hadoop calculate free space in this directory? As there is no concept called "free space in directory". Does hadoop consider free space available in D: drive in this example, as total free space in datanode? |
how hadoop decide datanode free space |

I am using uuid as id for the MySQL db. But when I try to retrieve using id, it's returning null rather than the correct object. I crossed check the db using workbench, the record is there but its not retrieving when trying to do usig JPA. I have following classes
BaseEntity:
```
@Getter(AccessLevel.PUBLIC)
@MappedSuperclass
public abstract class BaseEntity {
@Id()
@GeneratedValue(strategy = GenerationType.UUID)
UUID id;
@CreationTimestamp
Date createdAt;
}
```
ArticleRepo:
```
@Repository
public interface ArticlesRepository extends JpaRepository<ArticleEntity, UUID> {
ArticleEntity findBySlug(String slug);
Optional<ArticleEntity> findById(UUID id);
}
```
ArticleService:
```
@Service
public class ArticlesService {
public final ArticlesRepository articlesRepository;
public final UsersRepository usersRepository;
public ArticlesService(
ArticlesRepository articlesRepository,
UsersRepository usersRepository
) {
this.articlesRepository = articlesRepository;
this.usersRepository = usersRepository;
}
public List<ArticleEntity> getAllArticles(){
List<ArticleEntity> articlesIterable = articlesRepository.findAll();
return StreamSupport.stream(articlesIterable.spliterator(),false)
.collect(Collectors.toList());
}
public ArticleEntity getArticleBySlug(String slug){
var article = articlesRepository.findBySlug(slug);
if(slug==null){
return null;
}
return article;
}
public ArticleEntity createArticle(CreateArticleDTO createArticleDTO, String authorUsername){
var author = usersRepository.findByUsername(authorUsername);
return articlesRepository.save(
ArticleEntity.builder()
.title(createArticleDTO.getTitle())
.slug(createArticleDTO.getTitle().toLowerCase().replaceAll(" ","-"))
.subtitle(createArticleDTO.getSubtitle())
.body(createArticleDTO.getBody())
.author(author)
.build()
);
}
public Optional<ArticleEntity> getArticleById(UUID id){
return articlesRepository.findById(id);
}
}
Whenever I try to get a record using the UUID, I am getting null as opposed to the record.
```
Tried to store the UUID AS VARCHAR in MySQL db, that didnt work either:
```
public abstract class BaseEntity {
@Id()
@GeneratedValue(strategy = GenerationType.UUID)
@JdbcTypeCode(SqlTypes.BINARY)
UUID id;
@CreationTimestamp
Date createdAt;
}

I am using Polars (`{ version = "0.38.3", features = ["lazy", "streaming", "parquet", "fmt", "polars-io", "json"] }`) with Rust (`v1.77.0`) to process a large dataset (larger than available memory) inside a Docker container. The Docker container's memory is intentionally limited to 6GB using `--memory=20gb` and `--shm-size=20gb`. I am encountering an out of memory error while performing calculations on the dataset.
Here's an overview of my workflow:
1- Load the dataset from a Parquet file using scan_parquet to create a LazyDataframe.
2- Perform transformations on the dataframe, which is unnesting.
4- Write the resulting data to disk as a Parquet file using sink_parquet.
Here is a code snippet that demonstrates the relevant parts of my Rust code:
```rust
use jemallocator::Jemalloc;
use polars::{
prelude::*,
};
use std::time::Instant;
#[global_allocator]
static GLOBAL: Jemalloc = Jemalloc;
fn main() {
let now = Instant::now();
let mut lf = LazyFrame::scan_parquet(
"./dataset.parquet",
ScanArgsParquet {
low_memory: true,
..Default::default()
},
)
.unwrap();
lf = lf.with_streaming(true).unnest(["fields"]);
let query_plan = lf.clone().explain(true).unwrap();
println!("{}", query_plan);
lf.sink_parquet("./result.parquet".into(), Default::default())
.unwrap();
let elapsed = now.elapsed();
println!("Elapsed: {:.2?}", elapsed);
}
```
Despite using LazyFrame and enabling low_memory mode in ScanArgsParquet, I still encounter an out of memory error during the execution of the code.
I have tried the following:
- Using the jemallocator crate as the global allocator.
- Enabling streaming mode using with_streaming(true) for the LazyFrame operations.
- Using the `low_memory: true` in the scan_parquet function.
The printed plan indicates that every operation should be run in the streaming engine:
```
--- STREAMING
UNNEST by:[fields]
Parquet SCAN ./resources/dataset.parquet
PROJECT */2 COLUMNS --- END STREAMING
DF []; PROJECT */0 COLUMNS; SELECTION: "None"
```
However, I am still running into memory issues when processing the large dataset (Parquet file size = 20GB).
My questions are:
- Why I'm getting the OOM error while everything is indicating it is using the streaming engine ?
- Is there another way to leverage disk-based processing or chunking the data to handle datasets larger than memory?
Any guidance or suggestions on how to resolve this issue would be greatly appreciated. Thank you in advance! |

I'm trying to develop a school schedule generator in JavaScript for a high school with various subjects, teachers, and classes. The goal is to create a balanced and efficient schedule that minimizes conflicts while considering teacher preferences and availability.
The teacherβs subjects that he teaches are predetermined, and I have already distributed the teacherβs lectures equally over his working days, based on the number of weekly lectures for each subject and the number of teacherβs working days. However, when I come to distributing the teacherβs lectures among the different classes, I find a problem with the method of distributing the lectures equally across all classes without... Injustice to one of the teachers (I am not looking for an ideal method, but at least it is acceptable)
If I wanted to distribute the lectures to one class and the teacher did not teach more than one subject in more than one class, it would be easy, but I find it difficult to distribute the teachersβ lectures to all classes in the most fair way.
**Constraints:**
So, I'm struggling with the algorithm for subject distribution. Ideally, I'd like an efficient algorithm that can handle these constraints:
1. Balanced subject distribution across classes throughout the week.
2. Respecting teacher preferences unavailable days
3. Distributing teachersβ lectures to classes in an organized and fair manner for all.
4. distributing lectures equally during workdays, with one day the teacher completing his lectures early.
The Constraints seem complicated but I wanted to make it as clear as possible
**Additional Information:**
I'm familiar with basic object-oriented programming concepts in JavaScript and have looked at some online resources on scheduling algorithms. However, they seem too complex for my needs.
Are there any efficient algorithms suitable for this scenario, or can you suggest an approach for distributing subjects effectively while considering the mentioned constraints?
**Example Data:**

const daysOfWeek = ["Sat", "Sun", "Mon", "Tue", "Wed", "Thr"];

**Expected Output**:
I expect the output to be a weekly schedule for each class, with lectures of teachers evenly distributed across the working days.
For example(like this but in a efficient way):

The problem in your code is that `winsound` accepts `.wav` files, not `.mp3`. You can use any online converter to convert your `.mp3` audio file to `.wav`. Then, it should work.

I am having trouble reading a large .dat file into R.
I am using
```
data <- read.table("...2018029_ascii/FRSS108PUF.dat", fill=TRUE)
```
This results in a large dataframe with V1, V2 as column names.
I am using the ASCII file at this link: https://nces.ed.gov/pubsearch/pubsinfo.asp?pubid=2018029

To transform Sales Order into Item Fulfillment:
var objItemFulfillment = record.transform({
fromType: record.Type.SALES_ORDER,
fromId: salesOrderID,
toType: record.Type.ITEM_FULFILLMENT,
isDynamic: false
});
Inventory Details are its own subrecords which may exist on each line.
When you are looping through the lines of your transformed Item Fulfillment, you can get the Inventory Details subrecord. If it doesn't exist, it will create one, otherwise you will be editing the existing one.
The `fieldId` for inventory details subrecord is `inventorydetail`.
let intIFLineCount = objItemFulfillment.getLineCount({sublistId: 'item'});
for (let i = 0; i < intIFLineCount; i++)
{
//this is your inventory details record
let objSubrecord = objRecord.getSublistSubrecord({
sublistId: 'item',
fieldId: 'inventorydetail',
line: i
});
}
Inventory Details is a record like any other, with its own sublist `inventoryassignment` which contains various fields, which you can find here:
[https://system.netsuite.com/help/helpcenter/en_US/srbrowser/Browser2023_2/script/record/inventorydetail.html][1]
[1]: https://system.netsuite.com/help/helpcenter/en_US/srbrowser/Browser2023_2/script/record/inventorydetail.html
Into this sublist you can set values like you normally would:
objSubrecord.setSublistValue({sublistId: 'inventoryassignment', fieldId: 'binnumber', value: 123456, line: x});
objSubrecord.setSublistValue({sublistId: 'inventoryassignment', fieldId: 'quantity', value: 20, line: x});
You can of course retrieve the values from existing inventory details too:
let binNumber = objSubrecord.getSublistValue({sublistId: 'inventoryassignment', fieldId: 'binnumber', line: x});
let quantity = objSubrecord.getSublistValue({sublistId: 'inventoryassignment', fieldId: 'quantity', line: x});
So the only annoying part is that you will be looping through the item sublist on the Item Fulfillment record, and on each line you will loop through another sublist, this time for the Inventory Details record. |

I'd like to create an online quiz application. I have in mind several types of exercises, including those for filling in the blank:
An exercise can require a user to enter the text:
```
Chemical energy produced by the ____ is stored in a small molecule called ____
```
Or to pick an option from the given list:
```
Mitochondria contain their own small (genes/cells/chromosomes)
```
I've been wondering about the best way to represent it in SQL schema. The blanks can appear in any part of the sentence, and there can be any number of blanks.
So I thought to represent it like this:
```java
class BlankExercise {
@ManyToOne
private List<Part> parts;
}
```
Where a `Part` can either be normal text or can be the blank. Thus each exercise is a sum of its parts:
```
Chemical energy produced by the ____ is stored in a small molecule called ____
```
would have 4 parts:
```
1. Chemical energy produced by the
2. (Mitochondria)
3. is stored in a small molecule called
4. (adenosine)
```
But that would require using a form of inheritance strategy - the `Part` would be a common parent class, which would be extended by `NormalPart` and `BlankEmptyPart` and `BlankOptionsPart`. But I've read that one should abstain from using inheritance with database entities, if at all possible, but it's difficult for me to see a solution that wouldn't involve inheritance.
The only other solution I could think of would use several tables a separate table for 'normal' text and separate tables for each type of blank:
```
exercise_texts
exercise_id text
```
and for the blanks where the user would have to type the whole word:
```
exerice_blanks_empty
exercise_id solution_text blank_index
```
and for the blanks where the user would pick an existing option:
```
exerice_blanks_options blank_index
exercise_id blank_id
```
with
```
exercise_blanks_options_list
blank_id option_text is_correct
```
Each blank table would have `blank_index` column, which would correspond to its position in the sentence: for instance, `Mitochondria` would have an index of `1` and `adenosine` would have an index of `3`.
I was wondering, which design is better, or neither is feasible and there is a better one? |

I'm student in practicing PintOS Project.
In Programming Project 3(Virtual Memory), I got ploblems about "preprocess in compiling" (C program).
I had tried all attempt that do my best, but I'm absolutely lost at this point on how to fix it.
Finally i come to here, had to ask you about this issue.
**error**
I finished stack growth part, so I am modifying `syscall.c` to implement `mmap`, but got problems in buid process. **the `spt` field is being recognized as an incomplete type and is not being excluded.**
**current situation**
The thread structure in question is declared in `thread.h`, and the type `supplemental_page_table` of spt, an element in the `thread` structure, is declared in `vm.h`. Above the thread structure in current thread.h
`#ifdef VM
#include "vm/vm.h"` is preprocessing the format vm.h. I am currently using the EC2 server(ubuntu 18.04) via SSH connection to VS code, and have tried solutions such as make clean, make, inserting and changing the order of #include preprocessing and forward declaration code, and rebooting + reinstalling EC2, but there is no progress.
**Questions**
1. If `vm.h`, where the `spt` structure is declared in `thread.h`, is included before the thread structure, shouldn't it be able to be used without problems?
```
...
#ifdef VM // I'm in project3(VM)
#include "vm/vm.h"
...
struct thread {
...
#ifdef VM
/* Table for whole virtual memory owned by thread. */
struct supplemental_page_table spt; // The spt structure is defined in vm.h.
...
```
```

2. Additionally, I have a customization called `tid_t` in `process.h` that is also defined in `thread.h`, and I've included it, but it doesn't reference it. I solved this problem by defining it again in process.h ,it is repeated, but I thought I'd ask along the same problem-context as above. For reference, I have the above issue after this.

your namespaces in the begining of the controller file should match the herirechy of the data sturcture
it should implement [PSR-4 autoloading standard][1].
check [laravel doc][2] for more details
so namespace for DokterController should be
namespace App\Http\Controllers\dokter;
and the use should be:
use App\Http\Controllers\docker\DokterController;
further try to refactor your code in your route file . Instead of calling controller during defining each route separately you shoud use Route::controller(controllername::class)->group(function(){
Route::get('routeurl','controllerMethodToCallForThisRoute');
})

I am having problems with gcc-11 C++ compiler when using multiple inheritance
and I want to call a specific method of the base class and I write using A::m1 explicitely.
Visual C++ 2022 works with this code, however gcc-11 fails and produces an error.
This is the code:
```
struct Base
{
void m1(){}
void m2(){}
void m3(){}
};
struct A: Base{};
struct B: Base{};
struct C: A,B
{
using A::m1;
void mc()
{
m1();
}
};
```
In MSVC++ 2022 it compiles ok, however gcc-11 fails with this error:
In member function 'void C::mc()':
'Base' is an ambiguous base of 'C' m1();
It is an error of GCC 11 compiler? how can overcome it? why it is not taking into account
the using statement? new GCC versions solve this issue?
(Note: I know that replacing m1() by A::m1() works but I want to take benefit of "using")
Probably many of you think that using virtual inheritance with Base solve the problem, it is
correct, but for some reasons I cannot use virtual inheritance in this case.
Another question, is there any way to take preference to ALL member of a base class instead of
writing one by one with "using" statement, instead of writing:
```
using A::m1;
using A::m2;
using A::m3;
```
to write something like:
```
using A::Base
```
Any help is wellcome.
Regards
Pedro
I tried to code with "using" in several ways but all of them failed with GCC 11 compiler
The answers in linked post do not answer why gcc compiler does not compile and MSVC++ compiles. It is not an alternative in gcc for compiling this exact piece of code?

I'm trying to implement a Batch Gradient Descent algorithm in python that takes in the training set, the learning rate, and the number of iterations as input arguments, and returns the weights. However, when I run it, within a few iterations the values for the parameters get exponentially large and eventually it returns 'nan'.

Our ASP.NET website is using `FormAuthentication`. After login success, it will add a cookie to client side. Here is the code.
```
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1,
username,
DateTime.Now,
expiration,
remember,
roles,
FormsAuthentication.FormsCookieName);
HttpCookie authCookie = new HttpCookie(FormsAuthentication.FormsCookieName, FormsAuthentication.Encrypt(ticket));
Response.Cookies.Add(authCookie);
```
Then I can see that a cookie with name `.ASPXAUTH` is created in client browser. Next time, when I visit the website, I can see that `HttpContext.Current.Request.IsAuthenticated` is marked into `true` automatically. I guess ASP.NET decrypt the cookie and get the user information.
How can I debug this process? I want to see the source code to find out how `HttpContext.Current.Request.IsAuthenticated` is assgined into true. |

The app crashes anytime I interact with just about any compose control. Just the release, the debug works fine. The error says:
androidx.compose.ui.R$id is missing hide_in_inspector_tag
The stacktrace is below.
This definitely some sort of R8 issue. I've been adding things to proguard config and got to the point you at least seeing the class and field names, but so far I can't get to keep the field.
I didn't have this problem on a release done a week ago. I updated the Android Studio to
Android Studio Iguana | 2023.2.1 Patch 1
with:
```
gradleplugin = "8.3.1"
gradleAndroidCommandPlugin = "1.6.2"
```
I feel like I must have some version mismatch, but I can't seem to find one.
I tried the following in proguard without luck:
```
-keep class androidx.compose.ui.R$id { *; }

It appears that it's important to express that you want the 7 specific items extracted by calling for tokens=1-7.
Token 1 will be %%G, with each successive, stipulated token using %%H, %%I, etc.
Wanting to express one line for each token comes by echoing them 1 echo command at a time for each token's variable, either as one per line stacked or parenthetically grouped sequentially with &s:
do (echo %%G) & (echo %%H) & (echo %%I)... etc
In total, the following worked for me:
`for /f "tokens=1-7" %G in ("1 2 7 16 21 26 688") do (
echo %G
echo %H
echo %I
echo %J
echo %K
echo %L
echo %M
)` |
You can create a RandomRange class, you can create as many as you want and put into a list
public class RandomRange
{
public int Start { get; set; }
public int End { get; set; }
public int Exception { get; set; }
public RandomRange(int start, int end, int exception)
{
Start = start;
End = end;
Exception = exception;
}
public int getRandomIndex()
{
Random random = new Random();
int index = random.Next(Start, End+1);
if (index > End)
{
index = Exception;
}
return index;
}
}
In your main program, simply call it
static void Main(string[] args)
{
Random random = new Random();
// Define your ranges
List<RandomRange> ranges = new List<RandomRange>
{
new RandomRange(2, 10, 15), // Represents indices from 2 to 10
new RandomRange(15, 20, 25), // Represents indices from 15 to 20
new RandomRange(25, 30, 35) // Represents indices from 25 to 30
};
//i use random here in this case, but u can simply change it to a user input
RandomRange selectedRange = ranges[random.Next(ranges.Count)];
Console.WriteLine($"Selected Index: {selectedRange.getRandomIndex()}");
}
You can then use the `selectedRange.getRandomIndex()` to get your list item
Note that there is no check for index out of bound exception and i presume you already done all the list indexing exception handling
I hope the RandomRange class is easy enough |
The reason I was getting trouble is because I was redirecting through my nav.php, which is an include file containing only the navbar information. When I put the window.location.href within my index.php, I was able to redirect with no issues. |
I'm trying to restrict my solution using vpasolve() to only integers but I can't seem to find any equation or parameter that does that. Here is the code below if it helps, the variable I'm trying to restrict is N. Any guidance would be much appreciated.
```
clc
clear
syms t L S N
height = 0.7;
width = 0.1;
Tdiff = 100;
h = 17;
Qmult = 6;
eff = 0.7;
k = 45;
EQN1 = height==N*(t+S);
m = ((2*height)/(k*t))^0.5;
Lc = L+t/2;
EQN2 = eff==(tanh(m*Lc)/(m*Lc));
EQN3 = Qmult * h*(width*height)*Tdiff==(eff*h*(2*3*Lc)*(Tdiff)*N)+(h*(width*(height-N*t))*(Tdiff));
EQN4 = 0.5== m*L;
vpasolve([EQN1, EQN2, EQN3, EQN4], [t L S N], [0.005 0.3 0.35 60])
```
I tried using different solve functions and different init parameters but nothing seems to help. |

**Problem**
* Merge `fr` and `events` based on a match between `events['Earnings_Date']` and the exact or *next* date in `fr['Date']` (so: 'looking backward' from `fr`'s point of view), grouped by column 'Symbol'. Keep only the first match.
**Setup**
Let's add 2 symbols (one expecting a match, one expecting zero). Also, it is perhaps easier to use [`pl.Expr.str.to_date`](https://docs.pola.rs/py-polars/html/reference/expressions/api/polars.Expr.str.to_date.html) instead of your [`pl.Expr.str.strptime`](https://docs.pola.rs/py-polars/html/reference/expressions/api/polars.Expr.str.strptime.html).
* `fr`
```python
import polars as pl
fr = (
pl.DataFrame(
{
'Symbol': ['A', 'A', 'A', 'B', 'B', 'C'],
'Date': ['2010-08-29', '2010-09-01', '2010-11-30',
'2010-09-05', '2010-12-01', '2010-09-01'],
}
)
.with_columns(pl.col('Date').str.to_date('%Y-%m-%d'))
.set_sorted(('Symbol', 'Date'))
)
fr

```
* `events`
```python
events = (
pl.DataFrame(
{
'Symbol': ['A', 'A', 'B'],
'Earnings_Date': ['2010-06-01', '2010-09-01', '2010-12-01'],
'Event': [1, 4, 7],
}
)
.with_columns(pl.col('Earnings_Date').str.to_date('%Y-%m-%d'))
.set_sorted(('Symbol', 'Earnings_Date'))
)

**Explanation**
* Use [`pl.DataFrame.join_asof`](https://docs.pola.rs/py-polars/html/reference/dataframe/api/polars.DataFrame.join_asof.html) (with default `strategy='backward'`).
* Next, inside [`ppl.with_columns`](https://docs.pola.rs/py-polars/html/reference/dataframe/api/polars.DataFrame.with_columns.html) apply [`pl.when`](https://docs.pola.rs/py-polars/html/reference/expressions/api/polars.when.html) to set duplicates to `None` (`null`):
* Use [`pl.struct`](https://docs.pola.rs/py-polars/html/reference/expressions/api/polars.struct.html) to create a single 'key' for the combination `['Symbol', 'Earnings_Date']` and check [`pl.Expr.is_first_distinct`](https://docs.pola.rs/py-polars/html/reference/expressions/api/polars.Expr.is_first_distinct.html).
* Where `True` we want to keep the values for `['Earnings_Date', 'Event']`, so we can pass [`pl.col`](https://docs.pola.rs/py-polars/html/reference/expressions/col.html) to `.then`. Where `False`, we will get `None`.

I have upgraded the ClickHouse version from 22.6.1.1985 to 24.3.1.2672, which has resolved the issue. This is due to the fact that prior to the update, ClickHouse (in its 2022 version) adjusted the Asia/Tehran timezone to UTC+4:30 after March 20th to accommodate daylight saving time. However, post-2022, Iran discontinued the observance of daylight saving time. Consequently, following the update, the Asia/Tehran timezone has reverted to UTC+3:30 after March 20th, as it was before the change and it considered by Clickhouse in latest version. |
I am tyring to display a video in the PDP page and wondering if its actually supported by Spartacus 6.5.
I don't see any specific documantation about it but I can see a <cx-video> attribute in the Spartacus code which makes me believe that video files are supported. But I get a error **'cx-video' is not a known element: "If 'cx-video' is an Angular component, then verify that it is part of this module."**
Do I have to import anything else in my modules to get it to work? normal images are working fine with <cx-media>.
Are video files supported by Spartacus and where can I get any documentation or sample example of it. |
Use video files in Spartacus PDP page using <cx-media |
