The STRICT_TRANS_TABLES sql_mode (which *should* be used wherever possible) unfortunately promotes some warnings to errors when in an insert/update/etc, even where you guard against it with checking the results of a function call.
You could temporarily disable it before your update:
set session sql_mode=replace(@@sql_mode, 'STRICT_TRANS_TABLES', '');
update ...
set session sql_mode=concat(@@sql_mode, ',STRICT_TRANS_TABLES');
but I prefer using a regexp (as you suggest). |
To group by `tagValue`, since this is an array field, you need to apply the [`$unwind`][1] pipeline step before the group to split the array so that you can get the actual count:
db.feed.aggregate([
{'$unwind': '$feedTag'},
{'$group': {
'_id': '$feedTag.tagValue',
'number': { '$sum' : 1 }
}},
{'$sort': { '_id' : 1 }}
])
The following is the equivalent example in **[Spring Data MongoDB][2]**:
import static org.springframework.data.mongodb.core.aggregation.Aggregation.*;
Aggregation agg = newAggregation(
unwind("feedTag"),
group("feedTag.tagValue").count().as("number"),
sort(ASC, "_id")
);
// Convert the aggregation result into a List
AggregationResults<Feed> results = mongoTemplate.aggregate(agg, "feed", Feed.class);
List<Feed> feedCount = results.getMappedResults();
From the above, a new aggregation object is created via the **[`newAggregation`][3]** static factory method which is passed a list of aggregation operations that define the aggregation pipeline of your Aggregation.
The firt step uses the unwind operation to generate a new document for each tag within the "feedTag" array.
In the second step the group operation defines a group for each embedded `"feedTag.tagValue"`-value for which the occurrence count is aggregated via the count aggregation operator.
As the third step, sort the resulting list of **`feedTag`** by their **`tagValue`** in ascending order via the sort operation.
Finally call the aggregate Method on the MongoTemplate to let MongoDB perform the actual aggregation operation with the created Aggregation as an argument.
Note that the input collection is explicitly specified as the `"feed"` parameter to the aggregate Method. If the name of the input collection is not specified explicitly, it is derived from the input-class passed as first parameter to the newAggreation Method.

I am building a simple budget tracker, and I'd like to let user to filter by apps name.
Below is my code.
```json
[
{
"status": "on",
"id": "NZMwD83Nxg",
"name": "GTA_UA_UAC_Android_01_DAU",
"dailyBudget": 800,
"apps": [
{
"name": "app 1",
"icon": "https://marketing-0-7-0-85-220.png/230x0w.webp"
},
{
"name": "app 2",
"icon": "https://marketing-0-7-0-99-220.png/230x0w.webp"
}
],
"currency": "USD",
},
{
"status": "on",
"id": "aXly0x0vX6",
"name": "GTA_UA_UAC_Android_02_DAU",
"dailyBudget": 65,
"apps": [
{
"name": "app 3",
"icon": "https://marketing-0-7-0-85-220.png/230x0w.webp"
}
],
"currency": "USD",
}
]
```
And this is my column type.
```javascript
type AppsType = {
name: string;
icon: string;
};
export type MainCampaign = {
id: string;
name: string;
status: string;
apps: AppsType[];
dailyBudget: number;
currency: string;
};
export const columns: ColumnDef<MainCampaign>[] = [
{
accessorKey: "icon",
header: ({ column }) => (
<Button
variant="ghost"
onClick={() => column.toggleSorting(column.getIsSorted() === "asc")}
>
Apps
<ArrowUpDown className="ml-2 h-4 w-4" />
</Button>
),
cell: ({ row }) => {
const apps: AppsType[] = row.getValue("apps");
return (
<div style={{ display: "flex", gap: "10px" }}>
{apps.map((app, index) => (
<Avatar key={index}>
<AvatarImage src={app.icon} alt={app.name} />
<AvatarFallback>{app.name}</AvatarFallback>
</Avatar>
))}
</div>
);
},
},
{
accessorKey: "apps",
header: ({ column }) => (
<Button
variant="ghost"
onClick={() => column.toggleSorting(column.getIsSorted() === "asc")}
>
App Names
<ArrowUpDown className="ml-2 h-4 w-4" />
</Button>
),
cell: ({ row }) => {
const apps: AppsType[] = row.getValue("apps");
return apps.map((app, index) => <div key={index}>{app.name}</div>);
},
},
{
accessorKey: "name",
header: ({ column }) => {
return (
<Button
variant="ghost"
onClick={() => column.toggleSorting(column.getIsSorted() === "asc")}
>
Campaign Name
<ArrowUpDown className="ml-2 h-4 w-4" />
</Button>
);
},
},
...
]
```
This is my Input inside data-table for now, and it's worked when using `apps`, no result after typing.
```javascript
<div className="flex items-center py-4">
<Input
id="filter-app"
placeholder="Filter App..."
value={table.getColumn("apps")?.getFilterValue()?.toString() ?? ""}
onChange={(event) =>
table.getColumn("apps")?.setFilterValue(event.target.value)
}
className="max-w-sm"
/>
</div>
```
I have logged the app names, and the result looks like this: ["app1", "app2"], ["app3"]. My initial thought was to check if they include the filter value, then return the string, but I got stuck when implementing the function.
Would really appreciate your guidance.

I'm currently working on a CSS layout where I have a **fixed parent div** containing another div. I want the inner div to be **fixed relative to the body**, not its parent.
Code (Tailwind):
```
<div class="h-screen bg-red-100">
<div class="fixed left-1/2 top-1/2 h-80 w-80 -translate-x-1/2 -translate-y-1/2 bg-red-300">
<div class="fixed top-10 h-40 w-40 bg-red-600">I want to make this div fixed relative to body</div>
</div>
</div>
```
[Tailwind Playground][1]
Is there a way to achieve this without JavaScript? If not, how can I accomplish it using JavaScript?
I've also researched extensively and searched on Stack Overflow, but I couldn't find a solution that fits my exact requirements.
Thank you!

I have a firebase project.
I am calling an external api via cloud function in the hope the api key (stored in env variable) will be less discoverable.
While I have managed to get the following code working in the emulator, it doesn't work after deployment.
```
const {onRequest} = require("firebase-functions/v2/https");
const fetch = require("node-fetch");
const makeRequest = async (req, res) => {
const apiKey = process.env.KEY1;
const apiUrl = `[externalAPIurl]&key=${apiKey}`;
try {
const response = await fetch(apiUrl);
const data = await response.json();
res.set("Content-Type", "application/json");
res.status(200).send(JSON.stringify(data));
} catch (error) {
console.error("Error:", error);
res.status(500).send("Internal Server Error");
}
};
exports.helloWorld = onRequest(makeRequest);
```
Postman tells me that it's a lack of authentication being passed in the header (error 403).
I have struggled to adapt existing code (Google samples/turtorials, and community-provided excerpts). For example:
1. The following excludes req, res parameters and isn't obviously amenable to calling an external api (url)
https://cloud.google.com/functions/docs/samples/functions-bearer-token?hl=en
2. The following documents how one might create authenticated functions: https://stackoverflow.com/questions/57589339/how-to-invoke-authenticated-functions-on-gcp-cloud-functions
But the linked documentation suggests the approach is for development purposes (only?): https://cloud.google.com/functions/docs/securing/authenticating
3. This is very close, but is 1st gen and lacks the external api call: https://github.com/firebase/functions-samples/blob/main/Node-1st-gen/authorized-https-endpoint/functions/index.js
For context, the plan is to anonymously authenticate all users of the website. If anyone can point me in the right direction, that would be sweet. |

**Key Features:**
**Modularization:** I modularized my code by breaking it down into functions for adjusting break and session times, updating the time display, starting the session, and stopping/resetting the clock. This approach promotes code reuse and maintainability.
**Event Handling:** Event listeners are used to handle user interactions, such as increasing/decreasing break and session times, starting the clock, and resetting it, making the application interactive and user-friendly.
**Error Handling:** I implemented basic error handling to ensure that session and break times do not become negative and are capped at a minimum of 0.
**Functionality:** The Pomodoro clock alternates between session and break periods based on user-defined times, providing a functional and intuitive experience.
**Request for Feedback:**
I would appreciate feedback on the overall structure and readability of my code, as well as suggestions for optimization and improvement. Additionally, any advice on best practices or alternative approaches would be valuable for my learning journey.
Thank you for your time and assistance! |

Hello,
I’m currently integrating a custom export functionality. My goal is to add an export button to display “Save as CSV” but the text is rendering as undefined.
import React, { useEffect, useState } from 'react';
import CanvasJSReact from '@canvasjs/react-charts';
const { CanvasJSChart } = CanvasJSReact;
function Chart({ isLoading, data }) {
// Default chart options setup
const defaultOptions = {
animationEnabled: true,
exportEnabled: true,
theme: 'dark2',
// Additional options...
};
const [chartOptions, setChartOptions] = useState(defaultOptions);
useEffect(() => {
// Conditional logic based on <code>isLoading</code> and <code>data</code>
if (isLoading) {
setChartOptions({ ...defaultOptions, /* Loading state */ });
} else if (data?.length > 0) {
setChartOptions({ ...defaultOptions, /* Data available state */ });
} else {
setChartOptions({ ...defaultOptions, /* No data state */ });
}
}, [isLoading, data]);
return (
<CanvasJSChart
options={chartOptions}
onRef={(chart) => {
if (chart?.get("exportEnabled")) {
const text = document.createTextNode("Save as CSV");
const exportCSV = document.createElement("div");
exportCSV.appendChild(text);
exportCSV.setAttribute('style', <code>padding: 12px 8px; background-color: ${chart.toolbar.itemBackgroundColor}; color: ${chart.toolbar.fontColor}</code>);
exportCSV.addEventListener('mouseover', () => {
exportCSV.setAttribute('style', <code>padding: 12px 8px; background-color: ${chart.toolbar.itemBackgroundColorOnHover}; color: ${chart.toolbar.fontColorOnHover}</code>);
});
exportCSV.addEventListener('mouseout', () => {

On Windows 10:
Click start, search for "environment variables".
or
Use windows + R key to run command, run the following "sysdm.cpl"
then (if used win+R key): go to advanced tab, theres a box (system variables)
Then in system variables search for "Path",
click on it, click "Edit". A new window pops up. Click "New" and paste in "C:\Program Files (x86)\Python\Scripts".
If the box does not have a variable named "path" click New to create one, set the name to "Path", and the value to "C:\Program Files (x86)\Python\Scripts". |

To me, the only difference is that the regular operation needs one more instantiation, and the result is held by this new instance. And thus the regular implementation should call the other.
[But](https://docs.python.org/3/reference/datamodel.html#emulating-numeric-types) : *these (in-place) methods should attempt to do the operation in-place (modifying self) and return the result (which could be, but does not have to be, self). If a specific method is not defined, or if that method returns NotImplemented, the augmented assignment falls back to the normal methods.*
Here, i understand that the standard way is the opposite of mine : iadd relies on add.
Why ?
A bit of context : the question came while implementing a Polynomial class, for learning purpose. I have written:
```
class A:
...
def __iadd__(self, other):
"processing resulting in modification of attributes of self"
returning self
def __add__(self, other):
res = self.copy() # copy() being implemented as well
res += other
returning res
``` |
Why regular operations are not based on their in-place corresponding operation? |

I have recently authored a new hierarchical clustering algorithm specifically for 1D data. I think it would be suitable to the case in your question. It is called `hlust1d` and it is written in `R`. It is available under [this link](https://CRAN.R-project.org/package=hclust1d).
The algorithm addresses @Anony-Mousse's concern: it takes advantages of the particular structure of 1D data and runs in O(n*log n) time. This is much faster than general-purpose hierarchical clustering algorithms.
To segment your data into 3 bins (clusters) as you require in your question, you could run the following code
```
library(hclust1d)
dendrogram <- hclust1d(c(1, 1, 2, 3, 10, 11, 13, 67, 71))
plot(dendrogram)
```
I can't post images, but it produces the output which can be [accessed here](https://i.stack.imgur.com/jAf3k.png).
Now, having a look at the dendrogram tree one can see that cutting at the height of aprox. 10 results in the segmentation required.
```
cutree(dendrogram, h=10)
# 1 1 2 3 10 11 13 67 71
# 1 1 1 1 2 2 2 3 3
```
The clustering is hierarchical, meaning that what you get is a hierarchy of clusters (a dendrogram) and it is up to you to decide, which number of clusters fits your particular data best. It is both an advantage (flexibility) and disadvantage (you have to decide something) of this method. For instance, another good cut of the dendrogram, as can be seen on a plot, is located somewhere between the heights of 20 and 60, resulting in two clusters:
```
cutree(dendrogram, h=20)
# 1 1 2 3 10 11 13 67 71
# 1 1 1 1 1 1 1 2 2
```
For more complex data, you could also experiment with other linkage functions using the `method` argument, like this:
```
dendrogram <- hclust1d(c(1, 1, 2, 3, 10, 11, 13, 67, 71), method="ward.D2")

Generally, Ward linkage method would give you a clustering similar to K-Means (the loss function in both methods is the same with Ward hierarchical clustering being a greedy implementation) but the hierarchical clustering let's you decide what is an appropriate number of clusters with a dendrogram in front of you, while you have to provide that number for K-Means up front.
The list of all supported linkage methods can be read with a use of
```
> supported_methods()
# [1] "complete" "average" "centroid" "true_median" "median" "mcquitty" "ward.D" "ward.D2" "single"

Many of the answers above already mention it, just to reiterate.
Using Ansible on a system with multiple versions of python, for instance following these steps on Rocky 9.3:
```
python3.11 -m venv venv
source venv/bin/activate
pip install -U pip
pip install ansible
pip install selinux
```
And following that with `yum install libselinux-python3` makes a skew in the libraries.
The error pops up because 'selinux' (using python3.11) cant find 'libselinux' which is installed on a system using python3.9 .
So far the path of least resistance would be to reinstall ansible with the system level python3. |
Your code might compile now, but it will not work as you expect.
`INT_MIN`/`INT_MAX` are the min/max values for an `int`.
It is typically **32 bit** and therefore the values that you used before were probably **–2147483648** and **2147483647** respectively (they could be larger for 64 bit integers).
On the other hand `INT8_MIN`/`INT8_MAX` are min/max values for a **8 bit** signed integer (AKA `int8_t`), which are **-128** and **127** respectively.
In order to get the behavior you had before, you should use `std::numeric_limits<int>::min()` and `std::numeric_limits<int>::max()`, from the [<numeric_limits> header][1].

Although @oguz-ismail's answer would work with the sample output provided, it seems that actual `equery` output is very strange when fed into a pipe.
This convoluted commandline seems to work around the problems:
```
script -B /dev/null -E never -f -q -c '
eix-installed -a | xargs equery depends
' |
tr -d '\r' |
grep -v 'Unmatched removal atom' |
awk '!/\n/' RS= ORS='\r\n'
```
* `script` makes `equery` believe it is talking to a terminal
* `tr` strips the carriage returns added by `script`
* `grep` filters some non-dependency info (per @konsolebox comment)
* `awk` splits on empty lines and filters out multi-line records
- setting `ORS` is only needed for terminal output

Weird no one mentioned this but, you can get location from `react-router-dom` using the `useLocation` hook. So you can just use that in the dependency array.
[Docs here][1]
```lang-js
const location = useLocation();
useEffect(() => {
console.log(location);
}, [location.pathname]);
```
Edit:
This is a solution only for using react with web and you are using the `react-router-dom` library for web.
If you want to achieve this for cases where you don't have that library installed, and the other answers didn't work for you, you would need to do the following:-
1. Add a context<sup>{1}</sup> to the top level of your App.
```lang-js
export const LocationContext = React.createContext<LocationContextObject>(
null!
);
```
2. Set the value of this context provider with the location
3. When navigating, you need to update this context value with the new location, (create a custom navigation function and use it everywhere)
** Inspired from the source code of [remix-run/react-router][2] (react-router-dom)
{1} - You may want to search a bit more if you want to use a context at the top level since there are [pitfalls](https://blog.logrocket.com/pitfalls-of-overusing-react-context/) you need to keep in mind. You could also store it in a state management library of your choice.

I'm optimizing some work I did moving from Orange to Python code, but I'm having some problems with image Embedders.
I'm trying to recreate my work using Tensorflow/Keras, but the outputs of the VGG16 networks but the 4096 outputs of the activation layer of the penultimate FC layer for this architecture, using Orange and Keras, are different.
[In the Orange documentation it is written:](https://i.stack.imgur.com/X1Kya.png)
For python:
```
model_vgg = VGG16(include_top=True, weights='imagenet', pooling=None, input_shape=(224, 224, 3))
model_vgg16 = Model(inputs=model_vgg.input, outputs=model_vgg.layers[-2].output)
```
[Keras VGG16](https://i.stack.imgur.com/31umC.png)
To reshape some images to 224x244 pixels i use the same package and code of function load_image_or_none -> https://github.com/biolab/orange3-imageanalytics/blob/master/orangecontrib/imageanalytics/utils/embedder_utils.py
And get the same image resized to 224x224 used for VGG16 in Orange, by widget Save Image.
[My resized images and Orange images are the same](https://i.stack.imgur.com/GBO7o.png)
Perhaps I'm making a mistake during preprocessing, since in the Orange documentation it is written that they use the original weights of the model.
To preprocess the images i try the Keras preprocess_input of VGG16, and manually
```
def process_vgg16(imgs):
output = np.zeros(imgs.shape)
VGG_MEAN = np.array([103.939, 116.779, 123.68], dtype=np.float32)
for i in range(0, imgs.shape[0]):
b = np.array(imgs[i,:,:,2], dtype=np.float32)
g = np.array(imgs[i,:,:,1], dtype=np.float32)
r = np.array(imgs[i,:,:,0], dtype=np.float32)
output[i,:,:,0] = b - VGG_MEAN[0]
output[i,:,:,1] = g - VGG_MEAN[1]
output[i,:,:,2] = r - VGG_MEAN[2]
#output = output/255
return output
```
Note: The images are in gray scale, so all channels are the same.
Results:
[First three output of an image in orange (VGG16)](https://i.stack.imgur.com/Jex5Z.png)
[First three output of an image in Keras (VGG16)](https://i.stack.imgur.com/T29ph.png)

This is not another of those questions, this is about parsing and interpreting PHP in the browser with JS.
How can you run PHP in JavaScript? I am not asking about running PHP in the server and then send the resulting string to the browser as JavaScript. I am literally talking about JavaScript parsing and running PHP.
This might be useful in many places:
- An express Node.js app that has to use a PHP module.
- A small REPL for the browser that does not need a whole VM per instance. Ideal for learning PHP.
- Making a template engine for a static site constructor.
I've searched around and found [`php-parser`](https://github.com/glayzzle/php-parser) and [`babel-preset-php`](https://gitlab.com/kornelski/babel-preset-php), but nothing to run it. Ideally I'm looking for something like this, though I couldn't find anything through Google/SO/etc:
<!-- language-js -->
// No server needed, "just" Javascript parsing PHP
alert(php(`<?= "Hello world" ?>`));
If you know a better way than my own answer, please feel free to share it! I'm very curious about what the community thinks. |
Here's my two cents on the matter,
Dependency Injection is about passing the required dependencies (objects or services) into a class from an external source, rather than creating instances of those dependencies within the class itself.
Why?
So that we can achieve loose coupling between classes by taking advantage of interfaces and abstract classes.
(or one can say to achieve IoC)
Why?
Because this allows us to:
1. Adhere to the Open/Closed Principle.
2. Write polymorphic code.
3. Facilitate unit testing of classes that depend on external APIs
or services by providing mock or stub implementations of those
dependencies.
4. Clearly define and manage the dependencies of classes.
There is a concept part of it and a design pattern part of it
The concept part of it is that understanding DI can achieves separating concern, IoC. Above are few benefits (from many that SoC gives), It’s about what you trying to achieve by delegating object creation.
The design pattern is how to achieve it in terms of managing dependencies; by controlling the object creation and "injecting" into a class rather than the class creating its dependencies.
> Design patterns are half-baked solutions for common problems.
Example of DI design pattern implementation.
In the .NET Framework, controller objects are managed by the .NET Core framework itself, it provides a means to inject objects into controllers using the `services.AddScoped` method.
So we can see .NET Framework itself implements its version of the DI design pattern providing us a way to register our dependencies and make it available to all of our controllers.

For setting up FSLogix with Azure Files for Azure Virtual Desktop. You can follow the steps below-
*Prerequisites*
- Azure subscription with permissions to create resources.
- Azure Virtual Desktop environment set up.
- Azure Files share created for FSLogix profiles.
- FSLogix agent installed on AVD VMs.
create a new storage account if you haven’t.
az storage account create --name <YourStorageAccountName> --resource-group <YourResourceGroupName> --location <Location> --sku Standard_ZRS --kind StorageV2
Create the file share
az storage share create --name <YourFileShareName> --account-name <YourStorageAccountName>
Get storage account key
$storageKey = az storage account keys list --resource-group <YourResourceGroupName> --account-name <YourStorageAccountName> --query "[0].value" --output tsv
Assign appropriate permissions to the Azure File Share for your AD domain service.
In your AVD host pool, create a logon script to mount the file share when the user logs in.
```
$storageAccountName = "<YourStorageAccountName>"
$fileShareName = "<YourFileShareName>"
$driveLetter = "F"
$storageKey = "<YourStorageKey>"
#Mapping the drive
New-PSDrive -Name $driveLetter -PSProvider FileSystem -Root "\\$storageAccountName.file.core.windows.net\$fileShareName" -Persist -Credential (New-Object System.Management.Automation.PSCredential ("Azure\$storageAccountName", (ConvertTo-SecureString $storageKey -AsPlainText -Force)))
```
Configure FSLogix via PowerShell i.e. on the AVD VMs, set the FSLogix registry keys.
```
$regPath = "HKLM:\SOFTWARE\FSLogix\Profiles"
$fileSharePath = "\\$storageAccountName.file.core.windows.net\$fileShareName"
# Ensure the registry path exists
if (-not (Test-Path $regPath)) {
New-Item -Path $regPath -Force
}
# Configure the VHDLocations registry key
Set-ItemProperty -Path $regPath -Name "VHDLocations" -Value $fileSharePath
# Enable FSLogix Profile Containers
Set-ItemProperty -Path $regPath -Name "Enabled" -Value 1
```
Done. You can now log in to your AVD session and ensure that the F: drive is mounted and points to your Azure File Share.

Is there a way to manually set the values shown in the legend of a seaborn (or matplotlib) scatterplot when the legend contains a continuous variable (hue)?
For example, in the plot below I might like to show the colors corresponding to values of `[0, 1, 2, 3]` rather than `[1.5, 3, 4.5, 6, 7.5]`
```
np.random.seed(123)
x = np.random.randn(500)
y = np.random.randn(500)
z = np.random.exponential(1, 500)
fig, ax = plt.subplots()
hue_norm = (0, 3)
sns.scatterplot(
x=x,
y=y,
hue=z,
hue_norm=hue_norm,
palette='coolwarm',
)
ax.grid()
ax.set(xlabel="x", ylabel="y")
ax.legend(title="z")
sns.despine()
```

I addressed this issue (twice now) by using `fastlane` and reinstalling all simulators.
You can install fastlane with `brew install fastlane` and then reset all your simulators:
fastlane snapshot reset_simulators
This will wipe out all your current simulators so just make sure you haven't done any special configuration in/on them that you'll need to keep. But otherwise it should be a quickfix. |
Looking at `retry`'s [`RetryConfig#delay`](https://rxjs.dev/api/index/interface/RetryConfig) property I noticed you can pass a function instead of a number.
const CONDITION_NOT_REACHED = 'CONDITION_NOT_REACHED';
export function poll<TApiArgs, TApiResponse>(
input: PollCmd<TApiArgs, TApiResponse>
): Observable<TApiResponse> {
return input.apiCall().pipe(
switchMap((apiResponse) => {
if (input.shouldContinuePolling(apiResponse)) {
return throwError(() => CONDITION_NOT_REACHED);
}
return of(apiResponse);
}),
retry({ delay: (err, retryCount) => {
if (err === CONDITION_NOT_REACHED) {
return throwError(() => CONDITION_NOT_REACHED);
}
return timer(input.intervalInSeconds * CONVERT_SECONDS_TO_MS).pipe(take(1));
} }),
timeout({ first: input.timeoutInSeconds * CONVERT_SECONDS_TO_MS })
/*
At some point, manualForceStop passes from "false" to "true" and then,
I would like to unsubscribe and throw a specific error
*/
);
}
The observable returned from the function passed to `delay` has these properties:
* When it emits, the retry occurs
* If it throws, the error will be propagated
* If it doesn't emit, the error won't be propagated and it completes without errors
Then later on you can use it like this:
const myPoll$ = poll(/* [...] */);
myPoll$.subscribe({
error: err => {
if (err === CONDITION_NOT_REACHED) {
// do something here
}
},
}); |
I'm currently working on a React application where I'm using React Router for navigation. However, I'm facing an issue where the components associated with routes are not rendering properly.

import { BrowserRouter as Router, Routes, Route } from 'react-router-dom';
document.addEventListener('DOMContentLoaded', () => {
const rootElement = document.getElementById('root');
if (rootElement) {
ReactDOM.render(
<Router>
<Routes>
<Route path="/" element={<App />} />
</Routes>
</Router>,
rootElement
);
document.body.appendChild(document.createElement('div'));
}
});
```
**App.js**
```
import React from "react"
import {Route, Routes, } from "react-router-dom"

import Gym from "./Gym/Gym"
const App = () => {
return (
<Routes>
<Route path="/" component={Gyms}/>
<Route path="/gyms/:slug" component={Gym}/>
</Routes>
)
}
export default App;
```
**Gym.js**
```
import React from 'react'
const Gym = () => {
return <div>This is the Gym#show view for our app.</div>

Despite setting up the routes as above, when I navigate to the routes, I'm not seeing the expected components rendering. Instead, I just see a blank page.

I have a simple section a vue3 form which I would like to perform some validation on.
I would like to render an error message based on what error condition is being met.
When there is only one error condition to be met - the error message renders fine. however when there are multiple possible error messages, only an empty div renders, regardless of what error is being met
<label for="first_name">First Name:</label>
<input type="text" id="first_name" name="first_name" required alpha v-model="firstName" @blur="v.firstName.$touch()">
<div v-if="v.firstName.$error" class="error">
<p v-if="!v.firstName.$dirty">Please enter your first name.</p>
<p v-else-if="!v.firstName.minLength">First name must be at least 2 characters long.</p>
<p v-else-if="!v.firstName.alpha">First name can be characters only.</p>
</div>
<label for="last_name">Last Name:</label>
<input type="text" id="last_name" name="last_name" required alpha v-model="lastName" @blur="v.lastName.$touch()">
<div v-if="v.lastName.$error && v.lastName.$dirty" class="error">
<p>Last name must be at least 2 characters long.</p>
</div>
<script>
import { required, minLength, helpers, alpha } from '@vuelidate/validators';
import useVuelidate from '@vuelidate/core';
export default {
setup() {
const v = useVuelidate();
return { v };
},

return {
firstName: '',
lastName: '',
};
},
validations: {
firstName: { required, alpha, minLength: minLength(2) },
lastName: { required, alpha, minLength: minLength(2) },
},
};
</script>
In this example, when i enter 1 letter into last_name, the apt error message "Last name must be at least 2 characters long."
however if nothing/less than 2 letters/a non-alpha character is entered into first_name, an empty div renders with no p text inside. here is the rendered html when i inspect

To work nice on all browsers, I'd suggest this solution using jQuery :
HTML
``` html
<img src='./templates/lights3.jpg' alt="bg" id="bg"/>
```
CSS
``` css
#bg {
position: fixed;
top: 0;
left: 0;
z-index: -5000; // Yes I always overdo ^^ (that's not very clean)
}
.bgwidth {
width: 100%;
}
.bgheight {
height: 100%;
}
```
JQUERY
``` js
$(window).load(function() {
var theWindow = $(window),
$bg = $("#bg"),
aspectRatio = $bg.width() / $bg.height();
function resizeBg() {
if ( (theWindow.width() / theWindow.height()) < aspectRatio ) {
$bg.removeClass()
.addClass('bgheight');
} else {
$bg.removeClass()
.addClass('bgwidth');
}
}
theWindow.resize(resizeBg).trigger("resize");
});
```
This solution would be responsive and resize your background image relative to the size of browser window. |

The explanation of the two eggs problem can make some people confused in the first time, so we can understand the solution as follows:
Given x is the floor we start dropping the eggs.
- If it breaks, the total of trials in the worst case is **(x - 1)**
- If it doesn't break, how should we step up to the next floor? We can jump to floor **(x + x)th**, **(x + x + 1)th**... But it will increase the number of trials, we can try at x = 10:
. If it does break, we must try 10 times total in the worst case.
. If it does not break, and we step up to 10th + 10th = 20th and try, and if it breaks, we must try 1 (at floor 10th) + 1 (at floor 20th) + 9 = 11 times. Similarly, if we step up to x + 1, or x + 2 floor it will increase the number of trials.
Actually, we want the number of trials being equal in both cases, for that reason we will step up to x - 1 floor instead of x, x + 1.,etc. Finally, we will have an expression in general:
x + (x - 1) + (x - 2) + ... + 1.
And that's it.

I have made one discord bot in the past it work perfectly but when I tried makeing another just like that it don't work it doesn't respond to my messages in the server but it respond in the private dms I tried to debug it by print statements but it don't receive the message from the server, I have checked the permissions and remove and add the bot again and also made another one and new servers but both of them don't message in servers
It's the code I written.
```
import discord
import os
intents = discord.Intents.default()
intents.messages = True # Enable message events
key = os.environ['Key']
client = discord.Client(intents=intents)
@client.event
async def on_ready():
print('Connected!')
@client.event
async def on_message(message):
if message.author == client.user:
return
print(f"Received message: {message.content}") # Debug print statement
if message.content.startswith('hello'):
print('Responding to hello message') # Debug print statement
await message.channel.send('Hello!')
client.run(key)
```
Thank-you
The bot works fine when I chat in the dms but it can't read the messages on a server |
I am using this plugin, but I wanted to modify the php to redirect my uploads to a specific 'clientsimages' folder. However I can't seem to get it to work, any suggestions?
I'm using this code:
https://github.com/ruvictor/wc-file-attribute/blob/master/att.php
This is the code I tried, but it isn't uploading my images anymore. Prior to this it was just uploading everything to my normal media library:
if( ! empty( $_FILES['vicode-file-field']["name"] ) ) {
// WordPress environment
require( dirname(__FILE__) . '/../../../wp-load.php' );
$wordpress_upload_dir = wp_upload_dir();
// $wordpress_upload_dir['path'] is the full server path to wp-content/uploads/2017/05, for multisite works good as well
// $wordpress_upload_dir['url'] the absolute URL to the same folder, actually we do not need it, just to show the link to file
$i = 1; // number of tries when the file with the same name already exists
$file_image = $_FILES['vicode-file-field'];
$new_file_path = $wordpress_upload_dir['/wp-content/uploads/clientimages'] . '/' . $file_image['name'];
$new_file_mime = mime_content_type( $file_image['tmp_name'] );
if( empty( $file_image ) )
die( 'File is not selected.' );
if( $file_image['error'] )
die( $file_image['error'] );
if( $file_image['size'] > wp_max_upload_size() )
die( 'It is too large than expected.' );
if( !in_array( $new_file_mime, get_allowed_mime_types() ) )
die( 'WordPress doesn\'t allow this type of uploads.' );
while( file_exists( $new_file_path ) ) {
$i++;
$new_file_path = $wordpress_upload_dir['/wp-content/uploads/clientimages'] . '/' . $i . '_' . $file_image['name'];
}

Using gdal-async in nodejs, im trying to convert verctor files from geojson to dxf.
```
const dsGeoJSON2 = gdal.open('./upload2/objects.geojson');
const out2 = gdal.vectorTranslate('./upload2/objects.dxf', dsGeoJSON2, ['-f', 'DXF']);
```
the output file is emty, even with .kml but when i change to gpx for example it work. |
I have developed an app in .net Maui and would now like to hand it over to my customers. The only problem is that the company's laptops only allow apps to be installed that are from trustworthy authors. Even if I create an author certificate in visual studio and install it manually on a customer's laptop, the author (me) is still not recognized during the installation (Errorcode 0x800B010A). Is there a way to fix this error?

I am working on a custom board with two IMX7ULP. The thing I'm trying to do seems quite simple, the A7 from one IMX7ULP send a signal to the M4 of the other IMX7ULP, just an electrical signal, one of the pin of the A7 as output, one of the pin of the M4 as input (PTA16), no special communication protocol. We manage to set the pin of the A7 as an output (even checked with the multimeter) and we do what seems correct to set the pin as an input but nothing is read and it keeps returning me a value of 0.
The code I made looks like this
```
#define GPIO_HEARTBEAT_READ 16U
gpio_pin_config_t digitalInput = { //set as input
kGPIO_DigitalInput,
};
/* Init board hardware. */
BOARD_InitPins();
BOARD_BootClockRUN();
BOARD_InitDebugConsole();
CLOCK_EnableClock(kCLOCK_Rgpio2p0);
/* Init input GPIO. */
GPIO_PinInit(GPIOA, GPIO_HEARTBEAT_READ, &digitalInput);
int value = GPIO_PinRead(GPIOA, GPIO_HEARTBEAT_READ);
PRINTF("Value of HEARTBEAT_READ : %d\n", value);
PRINTF("Value of register of heartbeat : %x\n", READ_reg());
```
and value is set as 0 while the register read 0x10100 which is what I am expecting for a pin set as input.
I also checked the IOMUXC mode to make sure it is correctly set as GPIO :
```
void BOARD_InitPins(void) {
IOMUXC_SetPinMux(IOMUXC_PTA16_PTA16, 0U);
}
```
I even tried forcing it in pull-down to create a difference in potential at the pin but nothing changed. I'm currently running out of ideas, is there something I'm missing ? Is it more a hardware problem than software (if it's the case, I apologize and I'll be looking somewhere else)
Thank you in advance

The only issue which i see might be intefering with your ObjectMapper is the 2 extra modules which are added.
mapper.registerModules(securityModules());
mapper.registerModule(authorizationServerJackson2Module());
try removing these 2 and then try again. |
I am using Vue3 and Vue router 4, while tyring to run this.$router.push
it throws `leaveGuards.forEach is not a function`
I see that https://github.com/vuejs/router/blob/f776cbe1098596f53b5c2f696d29e1c02afd1fc1/packages/router/src/router.ts#L824 at this particular line for my application the leaveGuards is an empty object. Why is that? How can I resolve my error?
I tried
this.$router.push({
path: //
query: //
})
And router.js seems to be configured properly |
this.$router.push is causing a leaveGuards.forEach is not a function error |

You can define a new method on `Array` object's prototype. E.g:
Array.prototype.IsTrue = function () {
return true;
}
Then use it:
product.attributes.IsTrue()
But this method will exist on every instance of Array object. E.g: `[1,'abc'].IsTrue()` is a valid usage.
You can't define the extension method for only one interface of your choice, because javascript actually don't have the notion of `Interface` or `Type`. It's just a language feature that Typescript bring up to help your developer life easier.
The recommended approach in React world would be some Utility functions, you import and use them on demand. |

I am testing the m.if3 function in gekko by using conditional statements of if-else but I get two different outputs. The enroll_rate is 0.1 for the first 5 months and it switches to 0.3 for the remaining 45 months.
```
m = GEKKO(remote=False)
# parameters
sitecost = 9 # Cost per site
patcost = 12 # Cost per patient
num_pat = 50 # Required number of patients
recruit_duration = 50 # Duration of recruitment
# Define a piecewise function for the enrollment rate
enroll_rate = m.if3(recruit_duration - 5, 0.3, 0.1)
x = m.Var(integer=True, lb=1) # Number of sites
cost = m.if3(recruit_duration - 5, (0.3 * patcost * recruit_duration + sitecost) * x,
(0.1 * patcost * recruit_duration + sitecost) * x)
pat_count = m.if3(recruit_duration - 5, (0.3 * recruit_duration * x),
(0.1 * recruit_duration * x))
m.Minimize(cost)
m.Equation(pat_count >= num_pat)
m.solve(disp=False)
num_sites = int(x.value[0])
print(f'num_sites = {num_sites}')
print(cost.value[0])
print(pat_count.value[0])
```
```
# Parameters
sitecost = 9 # Cost per site
patcost = 12 # Cost per patient
num_pat = 50 # Required number of patients
recruit_duration = 50 # Duration of recruitment
# Define an enrollment rate based on recruit_duration
if recruit_duration > 5:
enroll_rate = 0.1
else:
enroll_rate = 0.3
# GEKKO Variables
x = 10 # Number of sites
# Calculate cost based on enrollment rate and site cost
cost1 = (0.1 * patcost * 45 + sitecost) * 12
cost2 = (0.3 * patcost * 5 + sitecost) * 12
cost = cost1 + cost2
# Calculate total patient count
pat_count1 = 0.1 * 5 * 12
pat_count2 = 0.3 * 45 * 12
pat_count = pat_count1 + pat_count2
print(pat_count)
print(cost)
```
I get different outputs even though I am doing the same thing in both of them.
I tried everything from using if-else statements to using if2 statements. |
Why does it provide two different outputs? [gekko] |

You can use the [`sx` prop][1]:
```javascript
const boxStyle = {
my: 4,
display: "flex",
alignItems: "top",
gap: 1,
p: 2,
...
};
...
<Box sx={boxStyle}></Box>
```
Alternatively, you can create a separate component for your specific box, like:
```javascript
const StyledBox = ({ children }) => (
<Box
my={4}
display="flex"
alignItems="top"
gap={1}
p={2}
>
{children}
</Box>
);
...
<Stack direction="row" spacing={2} border={1} borderColor="divider">
<StyledBox>
<TargetMetricIcon fontSize="medium" /> Target Metric
</StyledBox>
</Stack>
```
