Here is my `formSlice` and I am getting "Expression expected" after the closing brackets of the `builder` and the arrow function.
```javascript
import { createAsyncThunk, createReducer, createSlice } from "@reduxjs/toolkit";
import axios from "axios";
export const getform = createAsyncThunk("form/getForm", async () => {
try {
const result = await axios.get("http://localhost:5000/autoroute/");
return result.data;
} catch (error) {}
});
export const addform = createAsyncThunk("form/add", async (form) => {
try {
const result = await axios.post("http://localhost:5000/autoroute/", form);
return result.data;
} catch (error) {}
});
export const deleteform = createAsyncThunk("form/deleteForm", async (id) => {
try {
const result = await axios.delete(`http://localhost:5000/autoroute/${id}`);
return result.data;
} catch (error) {}
});
export const updateform = createAsyncThunk(
"form/deleteForm",
async ({ id, form }) => {
try {
const result = await axios.put(
`http://localhost:5000/autoroute/${id}`,
form
);
return result.data;
} catch (error) {}
}
);
createReducer(initialState, builder = {
form: [],
status: null,
});
export const formSlice = createSlice({
name: "form",
initialState,
reducers: {},
extraReducers: builder =>{
builder.getform(pending, (state) => {
state.status = "pending";
}),
builder.getform(pending, (state) => {
state.status = "success";
}),
builder.getform(pending, (state) => {
state.status = "fail";
}),
},
});
// Action creators are generated for each case reducer function
// export const { increment, decrement, incrementByAmount } = counterSlice.actions;
export default formSlice.reducer;
```
It says "expression expected" after the closing bracket `builder` of the `extraReducers`. I was working on an older version of the Redux-Toolkit but the error showed me that I need to match my code with the newer version. |

Vim also sports a `:terminal` command. Looking at [`:help :terminal`](https://vimhelp.org/terminal.txt.html#%3Aterminal) will reveal the following information:
```none
:[range]ter[minal] [options] [command]
Open a new terminal window.
If [command] is provided run it as a job and connect
the input and output to the terminal.
[...]
If [range] is given the specified lines are used as
input for the job. It will not be possible to type
keys in the terminal window.
```
This looks pretty complete: you can run a command (here: your Python interpreter) in a terminal, feeding it some lines from your buffer as input.
You would enter linewise Visual mode with <kbd>Shift</kbd><kbd>V</kbd>, select the lines to run and call
```
:'<,'>terminal python
```
where `'<,'>` stands for the current visual selection. Vim will already populate your command line with this when you type `:` in Visual mode.
On hitting enter, Vim will open a terminal window which will show the output (if any) of the Python code you just ran. Type `:q` to close the terminal and return to your normal editing.
For convenience, consider writing a command or a mapping to quickly run Python code. The following line will define a `:Python` command that runs the current visual selection or the whole buffer if nothing is selected:
```
:command -range=% Python <line1>,<line2>terminal python
```

I'm looking to update rows of a MySQL database from a Google Sheet. My current workflow is to import the existing table into one sheet in Google Sheets, copy it to another one where I make changes, then run a new script to update the table.
I could probably do this more efficiently but doing it this way means that I can't do anything automatically and risk breaking my database.
I have created a script where I only update one column and it works except that in my database the id column is not sequential as records have been deleted (eg it starts with row 3 then 5,6,7,9 etc). But my script doesn't account for that and will just use the Google Sheets Row ID to match it (eg in MySQL the first row is row 3, but in Google Sheets it'll be row 1). This means there's a mismatch.
My script is below and I've been tinkering but can't seem to make it work. The Unique IDs are in Column A.
The other thing is that I don't think my loop is efficient as the database will grow beyond 400 rows.
```
function UpdateDB(e) {
ss = SpreadsheetApp.getActiveSpreadsheet();
sheet = ss.getSheetByName("writeSheet");
hookn = sheet.getRange("M2:M300").getDisplayValues() ;
uid = sheet.getRange("A2:A300").getDisplayValues() ;
server = "1******";
port = '3306';
dbName = "*****";
username = "*******";
password = "*********";
url = "jdbc:mysql://" + server + ":" + port + "/" + dbName + "?characterEncoding=UTF-8";
conn = Jdbc.getConnection(url, username, password);
stmt = conn.createStatement();
for (i=0 ; i<400 ; i++ ) {
stmt.execute("UPDATE wp_tripetto_forms SET hooks ='" + hookn[i] + "' WHERE id = " + (i+1) + " ;");
}
conn.close();
}
```
While the rows do update, the IDs are not correct due to the script using the Google Sheet row ID as the MySQL unique ID. |

IIUC, you can build a directed graph with [`networkx`](https://networkx.org), then find the [`shortest_path`](https://networkx.org/documentation/stable/reference/algorithms/generated/networkx.algorithms.shortest_paths.generic.shortest_path.html#networkx.algorithms.shortest_paths.generic.shortest_path) between each node and `'0'`, then use that to map the `path_variable`:
```
import networkx as nx
G = nx.from_pandas_edgelist(df, source='m_eid', target='eid',
create_using=nx.DiGraph)
s = df.set_index('eid')['path_variable']
mapper = {n: '|'.join(s.get(x, '') for x in
nx.shortest_path(G, source='0',
target=n)[1:])
for n in df['eid'].unique()
}
df['complete_path'] = df['eid'].map(mapper)
```
Output:
```
eid m_eid level path_variable complete_path
0 1 0 0 0 0
1 2 1 1 0 0|0
2 3 1 1 1 0|1

12 13 10 3 0 0|1|3|0
```

[![organization graph, networkx graphviz][1]][1]
To make it easier to understand, here is a more classical path with the nodes ids (not the path_variables):
```
mapper = {n: '|'.join(nx.shortest_path(G, source='0',
target=n)[1:])
for n in df['eid'].unique()
}
df['complete_path'] = df['eid'].map(mapper)
```
Output:
```

This is not a question, but a summary of the steps required to address multi tenancy with spring (the partitioned approach where every table will have a tenant id column). I hope this helps others facing issues or looking for sample code ...
Two things to consider here -
1. The tenant id will be set in the header and passed with every http request.
2. I have enabled spring data rest in my application.
Firstly we need an determine the tenant for each http request. We can do that by intercepting the http request before it is processed, determine the tenant and store it until the request is completely processed and clear the tenant before the next http request is processed.
import jakarta.validation.constraints.NotNull;
@FunctionalInterface
public interface TenantResolver<T> {
String resolveTenantId(@NotNull T object);
}
Tenant context is the class which will store the tenant Id once it is identified by intercepting http requests.
public class TenantContext {
private static final ThreadLocal<String> tenantId = new InheritableThreadLocal<>();
public static void setTenantId(String tenant) {
tenantId.set(tenant);
}
public static String getTenantId() {
return tenantId.get();
}
public static void clear() {
tenantId.remove();
}
}
HTTPHeaderTenantResolver implements TenantResolver. X-TenantId is the name of the header which contains the tenant id and passed along with every http request.
import jakarta.servlet.http.HttpServletRequest;
import jakarta.validation.constraints.NotNull;
import org.springframework.stereotype.Component;
@Component
public class HttpHeaderTenantResolver implements TenantResolver<HttpServletRequest> {
@Override
public String resolveTenantId(@NotNull HttpServletRequest request) {
return request.getHeader("X-TenantId");
}
}
We then need to intercept each request by implementing HandlerInterceptor. In the preHandle() method, we resolve the tenant id and store it in the TenantContext class. In postHandle() and afterCompletion(), we clear the tenant id in TenantContext so we are ready to process new http requests.
@Component
@RequiredArgsConstructor
public class HttpRequestInterceptor implements HandlerInterceptor {
private final HttpHeaderTenantResolver tenantResolver;
@Override
public boolean preHandle(@NotNull HttpServletRequest request, @NotNull HttpServletResponse response,
@NotNull Object handler) throws Exception {
var tenantId = tenantResolver.resolveTenantId(request);
TenantContext.setTenantId(tenantId);
return true;
}
@Override
public void postHandle(@NotNull HttpServletRequest request, @NotNull HttpServletResponse response,
@NotNull Object handler, ModelAndView modelAndView) throws Exception {
TenantContext.clear();
}
@Override
public void afterCompletion(@NotNull HttpServletRequest request, @NotNull HttpServletResponse response,
@NotNull Object handler, Exception ex) throws Exception {
TenantContext.clear();
}
}
We then need to register HttpRequestInterceptor with Spring. We do that by implementing addInterceptors method of WebMvcConfigurer.
@Configuration
@RequiredArgsConstructor
public class WebConfigurer implements WebMvcConfigurer {
private final HttpRequestInterceptor httpRequestInterceptor;
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(httpRequestInterceptor);
}
}
With this, spring starts intercepting every http request and will try to resolve the tenant id. We now have to let hibernate know of the current tenant id so that hibernate can use the tenant id in all sql statements. We can do that by implementing the interfaces CurrentTenantIdentifierResolver and HibernatePropertiesCustomizer.
@Component
public class JPATenantIdentifierResolver implements CurrentTenantIdentifierResolver<String>, HibernatePropertiesCustomizer {
@Override
public String resolveCurrentTenantIdentifier() {
return (TenantContext.getTenantId() == null ? "" : TenantContext.getTenantId());
}
@Override
public boolean validateExistingCurrentSessions() {
return false;
}
@Override
public void customize(Map<String, Object> hibernateProperties) {
hibernateProperties.put(AvailableSettings.MULTI_TENANT_IDENTIFIER_RESOLVER, this);
}
}
Now hibernate is aware of the current tenant and it will add the tenant id in all sql statements.
Lastly, as I have enabled spring data rest, we will require one additional step. Spring does not intercept data rest urls by default. We need to define an addition bean to achieve this step.
@Configuration
public class JPARequestInterceptor {
@Bean
public MappedInterceptor addJPARestHttpInterceptor() {
return new MappedInterceptor(
null, // => maps to any repository
new HttpRequestInterceptor(new HttpHeaderTenantResolver())
);
}
}

I ran into the same issue; assuming you are injecting the Router instance using the inject method, try changing and injecting it using the constructor
constructor(private router: Router) {}
instead of ...
router = inject(Router);
Also be sure to use the correct import. After implementing the above code change I then realized a mistake I made; there is a difference between `Inject(Router)` and `inject(Router)`
import { Inject, inject } from '@angular/core';
You need to use the later. |
int originalHeight = header.height;
...
int lineSize = newWidth * header.bpp / 8 + padding;
int skippedLines = originalHeight - newHeight;
long skippedBytes = ((long)lineSize) * skippedLines;
fseek(inputFile, skippedBytes, SEEK_CUR); // Skip half the lines at top.
unsigned char *linePixels = malloc(lineSize);
if (!linePixels)
exit(137);
for (int y = 0; y < newHeight; y++) {
fread(linePixels, sizeof(unsigned char), lineSize, inputFile);
// You could copy the old padding.
//memset(linePixels + lineSize - padding, '\0', padding);
fwrite(linePixels, sizeof(unsigned char), lineSize, outputFile);
}
free(linePixels);
This will skip reading the first half containing the top lines (reversed **y** direction).
As already was commented there are more `header` fields (`biSizeImage`). The BMP format contains many variants.
Also copying a bit buffered, more the 3-4 bytes apiece, would be better.
As I introduced a `lineSize` I used that as buffer size. The code does not become _less_ but _more_ readable. |
The Best solution in these situation is **cleaning and rebuild your project.**
If it still doesn't work, try searching for duplicate resources, such as layout files, drawable resources, or other assets, within your Android project. |

I was searching for a way to achieve string concatenation in modern JavaScript. Here's a simple function that demonstrates how to concatenate two values into a single string:
```javascript
/**
* Concatenates two values into a single string.
*
* @param {any} arg1 - The first value to be concatenated.
* @param {any} arg2 - The second value to be concatenated.
* @returns {string} The concatenated string.
*/
const arg1 = 'Hello';
const arg2 = 'World';
const concatStr = (arg1, arg2) => String(arg1) + String(arg2);
console.log(concatStr(arg1, arg2)); // Output: HelloWorld

Goal of my program is to send data to the RS232 and read them in with a different function. I have a direct connection (wire) between the RS232 pin 2 and pin 3.
I'm getting randomly occurring timeouts in WPF when I'm reading the serial port, but I receive the data and can print it.
Create a serial port and a delegate in my class.
```
SerialPort _serialPort;
`public delegate void ReceiveData(object sender);`
```
Create a SerialDataReceivedEventHandler after InitializeComponent()
`_serialPort.DataReceived += new SerialDataReceivedEventHandler(SerialPort1_DataReceive);`
Define method for event.
```
private void SerialPort1_DataReceive(object sender, SerialDataReceivedEventArgs e)
{
Dispatcher.BeginInvoke(new ReceiveData(OutputDataToList), sender);
}
```
Define method for the delegate.
```
private void OutputDataToList(object sender)
{
SerialPort sp = (SerialPort)sender;
_inChar = '1';
while (_inChar != '\n')
{
try
{
_inChar = (char)sp.ReadChar();
}
catch (Exception ex)
{
MessageBox.Show("Error while receiving the serial port. " + ex.Message);
break;
}
if (_inChar != '\n')
{
_inMessage += _inChar;
}
}
if (_inMessage != "")
{
lstReads.Items.Add(_inMessage);
lstReads.SelectedIndex = lstReads.Items.Count - 1;
}
_inMessage = "";
}
```
In 70%-90% of the tests, the program works fine but sometimes, this error occurs:
[![enter image description here][1]][1]
I changed the timeout time. It gets better (but still happens sometimes) for shorter time but I don't understand why.
```
_serialPort.ReadTimeout = 500;
_serialPort.WriteTimeout = 500;
```

Emulator doesn't have an easy, built-in way to send custom `channelData`. There's a few different ways you can (kind of) do this, though:
### Debug Locally
As @EricDahlvang mentioned (I forgot about this), you can [debug any channel locally](http://web.archive.org/web/20200722110139/https://blog.botframework.com/2017/10/19/debug-channel-locally-using-ngrok/)
### WebChat
Emulator is built in [WebChat](https://github.com/Microsoft/BotFramework-WebChat), so the output will be the exact same. However, you miss some of the debugging functionality from Emulator.
1. Clone a [WebChat Sample](https://github.com/microsoft/BotFramework-WebChat/tree/54f67de4ff1740a050b2b5d9c07c3436e3ba314d/samples/15.a.backchannel-piggyback-on-outgoing-activities)
2. Edit `index.html` with `http://localhost:3978/api/messages` and your `channelData`
3. Run `npx serve`
4. Navigate to `http://localhost:5000`
### Modify Messages In OnTurnAsync()
This would only be for testing/mocking purposes and you'd want to ensure this doesn't go into production, but you can modify incoming messages inside `OnTurnAsync()` and manually add the `channelData`.
Something like:
public async Task OnTurnAsync(ITurnContext turnContext, CancellationToken cancellationToken = default(CancellationToken))
{
var activity = turnContext.Activity;
activity.ChannelData = new
{
testProperty = "testValue",
};
You could even make it happen with only specific messages, with something like:
if (turnContext.Activity.Text == "change channel data")
{
activity.ChannelData = new
{
testProperty = "testValue",
};
}
There's a lot of different options with this one, you just need to make sure it doesn't go into production. |
`orientation` does not seem to work as desired.\
Working with `aspect-ratio` may be the better way.
```
@media only screen and (max-aspect-ratio: 1/1){
//portrait
}
@media only screen and (min-aspect-ratio: 1/1){
//landscape
}

I have two columns, column 1 has product, column 2 has sales. I want to sort the table by sales descending. Total sales value/4 will give me quarter value.
I want to then create a group based on this quarter value.
Q1- 25% of data, Q2 - 50% of data, Q3 -75% of data, Q4 - 100%
Name the group - Q1, Q2, Q3, Q4 and omit any rows with zero sales.
Q1 then would be my highest selling products by value, Q2, second highest etc.
How to do it in sql ?
Sample table -
[](https://i.stack.imgur.com/FvjN1.jpg)
Expected output -
[](https://i.stack.imgur.com/qCBFh.jpg)
I tried a case when statement, but unlike the sample I have 1 million rows of data that needs to be grouped, hence hardcoding numbers in case when does not help, need some expert sql help here ! |
I have two components, one `Parent` and one `Child`. The latter should have `flex`-layout, so that it occupies 75% of the vertical space:
const Parent: FC<PropsWithChildren> = (props) => {
return (<View style={ styles.container }><MyChild /></View>)
}
const Child: FC<PropsWithChildren> = (props) => {
return (<View style={ styles.childSytle }/>)
}
const styles = StyleSheet.create({
container: {
flex: 1,
flexdirection: 'column'
},
childStyle: { flex: 9 }
});
What I want to achieve now, is get the actual size of my `Child`-component from within `Parent`. Is it possible to get the size of a component, when it's `flex`?
I already tried a `forwardref` for my `Child` to get a reference to `Child`. However I have no idea how to get its size. |

Suppose I have two entities : StudentDO and ParamDO. ParamDO is an entity that contains parameter code & values that are used throughout the application.
I have already cached this entity using EhCache as Second Level Cache.
@Entity
@Table(name="PARAM")
@jakarta.persistence.Cacheable
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
class ParamDO
{
@Column(name="TYPE")
private String type;
@Column(name="CODE")
private String code;
@Column(name="VALUE")
private String value;
}
`
Student Entity is associated to Param like this :
@Entity
@Table(name="STUDENT")
class StudentDO
{
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "SUBJECT_ID")
private ParamDO subject;
}
`
My problem is despite caching the ParamDO , on querying StudentDO , associated ParamDO entity is still being fetched from DB. Is there a way this can be prevented?
I have already set these properties in application.yml -
spring.jpa.properties.hibernate.cache:
use_second_level_cache: true
use_query_cache: true
From the logs I can see that a cache is created for ParamDO in EhCache.
What am i missing? |
Is there a way to fetch Associated Entity from second level Cache instead of hitting the DB in Hibernate? |

I'm beginning with network programming, so my first exercise was to create a client/server system with 2 VMs. So, I have a problem with the VMs, because they don't communicate, but if I run the code local on my machine in 2 terminal windows the code run correctly. Instead, in the VMs, the server go on "listening" but when I run the code from the client machine the server receive nothing.
Here is my server code:
#include <stdio.h>
#include <stdlib.h>

Both have their pros and cons. You also have the option to deploy multiple workers on a single service, one worker per service, or scale up the number or multiple services for a single worker topic. It all depends on what your performance and scaling requirements are. I'd suggest starting with a single worker and only scaling when you need. The exceptions to this that you might want to consider are:
- is there a benefit (for whatever reason) to have some activities/workflows implemented in Go and others in Java
- are there specific workflows or activities that are performance bottlenecks
- do you have multiple teams working on your infrastructure. If so, there may be benefits to each team having separately deployable workflows and applications. |
I was attempting to solve the question for deleting a node in BST, and saw a strange output. In the case where node has only right child, I was trying to delete that node and return its right child. Somehow, both of the codes below gave the correct result, even though it seems to me like only code 1 should work since we're trying to access a deleted node.
Can someone tell me why this happens?
cpp
Code 1:
Node* temp = root->right;
delete root;
return temp;
Code 2:
Node* temp = root;
delete temp;
return root->right; |

I have two tables: Schedules and Tasks, with a one-to-one relation
```
class Schedule extends Model
{
public function task() {
return $this->belongsTo(Task::class, 'task_id');
}
```
And the Task model has a one-to-many relation with Spatie Roles with a task_role pivot table:
```
class Task extends Model
{
public function roles() {
return $this->belongsToMany(Role::class);
}
```
How can I make a query that retrieves all schedules associated with tasks with permission for the logged in user?
For example:
Tasks:
| id | name |
| -------- | -------------- |
| 1| task1|
| 2| task2 |
| 3| task3 |
task_role:
| task_id | role_id |
| -------- | -------------- |
| 1| 1|
| 2| 3 |
| 3| 1|
Schedule:
| id| name | task_id |
| -------- | -------------- |-|
| 1| schedule1|1
| 2| schedule2|1
| 3| schedule3|5
Spatie model_has_roles:
| role_id| model_type| model_id|
| -------- | -------------- |-|
| 1| App\Models\User|2
| 2| App\Models\User|1
| 3| App\Models\User|5
When user2 is logged in he should be able to see only schedule 1 and 2. |

It seems you are setting the struct variable `test`'s attribute `a` to `5` only after you send the data.
Make sure to initialize the payload to what you want prior to sending. |
This is my first – ever post on Stack Overflow and it’s about an issue with the functionality of the VS Code terminal. Whenever I would run a piece of code via the terminal, the terminal would operate for several seconds and disappear. I would then be presented with a dialog box on the bottom – right corner of the screen, informing me that the terminal terminated with an exit code of ‘2’. Sometimes, the exit code would be different. It would be ‘3’, ‘1’, ‘-3’, or ‘-1’ depending on the situation. I’ve tried uninstalling VS Code, Windows Terminal, Windows Powershell and re – installing those programs only for the same issue to reoccur.
I also have an issue with the terminal not accepting input i.e., when you would type a line of syntax in the terminal, it freezes, causing the input to be unrecognizable. The operation stalled. There were plenty of articles that I read on Stack Overflow in relation to my issues, but none were successful. I’m reaching out for assistance from anyone and am open to any suggestions in regards to this matter.
Genuinely,
Jayloneal

You could try using the following formulas, this assumes there is no `Excel Constraints` as per the tags posted:
[![enter image description here][1]][1]
----------
=TEXT(MAX(--TEXTAFTER(B$2:B$7,"VUAM")*($A2=A$2:A$7)),"V\U\A\M\00000")
----------
Or, using the following:
=TEXT(MAX((--RIGHT(B$2:B$7,5)*($A2=A$2:A$7))),"V\U\A\M\00000")
----------
Or, you could use the following as well using `XLOOKUP()` & `SORTBY()`:
[![enter image description here][2]][2]
----------
=LET(
x, SORTBY(A2:B7,--RIGHT(B2:B7,5),-1),
y, TAKE(x,,1),
XLOOKUP(A2:A7, y, TAKE(x,,-1)))
----------
<sup> § Notes On **`Escape Characters`**: The use of `backslash` before & after the `V`, `U`, `A` & `M` is an **`escape character`**. Because the `V`, `U`, `A` & `M` on its own serves a different purpose, we are escaping it meaning hence asking Excel to **`literally form text`** with that character. </sup>
----------
Here is the **`Quick Fix`** to your **`existing formula`**, escape characters are not placed correctly, info on the same refer `§`
[![enter image description here][3]][3]
----------
=TEXT(MAX(IF($A$2:$A$100=A2, MID($B$2:$B$100, 5, 5)+0)),"V\U\A\M\00000")
----------
One more alternative way using `SORT()` & `REPT()` with **`Implicit Intersection Operator`** <sup>@</sup>
[![enter image description here][4]][4]
----------
=@SORT(REPT(B$2:B$7,(A2=A$2:A$7)),,-1)
----------
<sub>Notes on `Implicit Intersection Operator`<sup>**@**</sup> : It helps in reducing many values to a **`single value`**. **1.)** If the value is a single item, then return the item, **2.)** If the value is a range, then return the value from the cell on the same row or column as the formula., **3.)** If the value is an array, then pick the top-left value. --> Excerpts taken from `MSFT` Documentations, read [here][5]. </sub>

have recently deployed my Django project to a server, and while the index URL (mannyebi.com) loads correctly along with static files, accessing sub URLs such as mannyebi.com/blogs or even the admin panel (mannyebi.com/admin) results in a 404 error.
Locally, the project runs smoothly, indicating the issue may stem from the deployment configuration. I've ensured that all necessary URL patterns are defined in the urls.py files and that Django's admin app is properly installed and configured.
However, despite these measures, I'm still encountering difficulties accessing sub URLs beyond the homepage. Is there a specific configuration step or server setting that I might be overlooking to resolve this 404 error and enable access to sub URLs on my deployment? Any insights or troubleshooting suggestions would be greatly appreciated.
I deployed my Django project to a server. Upon navigating to sub URLs such as mannyebi.com/blogs or mannyebi.com/admin, I encountered a 404 error.
I verified that all necessary URL patterns were defined in urls.py and that Django's admin app was properly configured. I expected these URLs to load correctly, similar to how they did on my local development environment. However, despite these efforts, the 404 errors persisted.
I'm seeking guidance on resolving this issue and enabling access to sub URLs on the deployment. |

Another solution is to use [jupyverse](https://github.com/jupyter-server/jupyverse) instead of `jupyter notebook`, as `jupyverse` supports `kernels.allow_external_kernels` and `kernels.external_connection_dir` options to reuse existing running kernels.
```
pip install jupyverse[auth,jupyterlab]
```
```

CONNECTION_DIR="$(mktemp -d)"
(printf "%s\n" "$STARTUP_CODE" && sleep infinity) |

You can use the `grid` method instead of `pack` for the radio buttons. The `grid` method allows you to specify the row and column where each widget should be placed, enabling them to be positioned side-by-side.
url_pref_frame = tk.LabelFrame(self, text="URL Loading Preferences", padx=10, pady=10)
url_pref_frame.pack(pady=(20, 0), padx=(10, 0), fill=tk.X)
self.url_loading_preference = tk.StringVar(value="Most Recent")
row = 0 # Keep track of the current row for grid placement
tk.Radiobutton(url_pref_frame, text="Most Recent", variable=self.url_loading_preference, value="Most Recent", command=self.on_radio_change).grid(row=row, column=0, sticky=tk.W)
row += 1
tk.Radiobutton(url_pref_frame, text="Oldest", variable=self.url_loading_preference, value="Oldest", command=self.on_radio_change).grid(row=row, column=0, sticky=tk.W)
row += 1
tk.Radiobutton(url_pref_frame, text="Random page", variable=self.url_loading_preference, value="Random page", command=self.on_radio_change).grid(row=row, column=0, sticky=tk.W)
By using `grid` and specifying the row for each radio button, you ensure they are placed horizontally within the frame, making them all clickable.

My crontab file looks like:

And that script doesn't work. As I understand it, cron cannot detect the location of elixir. I run it on macOs Ventura.
How can I solve this problem? |

When I try to add a log using the below code (app for logging theatre trips) or search logs I'm sent to the App.g.i.cs autogenerated code. I've used breakpoints and stepped through the code and it seems to get through the whole subroutine and then when it gets to the end it throws this, perhaps its something with the UI?

I created a meta app using the email address associated with the base facebook account that created the page I am trying to get the posts from. In the Graph API Explorer I have selected my meta app and "user token". When I add the page ID to the query string field and click submit I get the error:"(#100) Object does not exist, cannot be loaded due to missing permission or reviewable feature, or does not support this operation. This endpoint requires the 'pages_read_engagement' permission or the 'Page Public Content Access' feature or the 'Page Public Metadata Access' feature."
But I don't see 'pages_read_engagement' in the list of permissions to choose from. Do I need to apply for "page public content access"?
Do I need to use a page token?
When I try to select "Page Access Token" as the token type I get a pop up saying "Sorry, something went wrong. We're working on getting this fixed as soon as we can."

I'm on Laravel 10, and created an API using sanctum.
In my controller, I want to call the local API to display in a view. The API works fine using postman, but when called in my controller the page doesn't load and times out.
Below is my module route in `module/api/routes/api.php`
```
Route::group(['middleware' => ['auth:sanctum', 'api']], function () {
Route::get('sample', [ApiController::class, 'sample']);
});
```
here is the HTTP code in my controller
```
$response = Illuminate\Support\Facades\Http::withHeaders([
"Accept"=> "application/json",
"Authorization" => "Bearer " . env('SANCTUM_AUTH')
])
->get(route('sample').'/', ['type' => '2']);
dd($response);
```
and this is the error i'm getting.
`cURL error 28: Operation timed out after 30006 milliseconds with 0 bytes received (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for http://127.0.0.1:8000/sample/?type=2`
my memory limit in php.ini is already set to 512M. I'm also on php 8.1.27

I wait until the page is loaded and use the "DOMContentLoaded" method to add eventhandlers on some p tags. This works until I open and close the modal, then the page/js freezes. Why does it freeze?

I've tried to render emoji flags such as notoColorEmoji (french flag) using google fonts, but for some reason they don't get rendered at all.
It works fine for other monochromatic fonts, but I couldn't find out how to make them work on windows (I'm using windows 10).
When I try this, the first two are rendered as expected, but the font "Noto Color Emoji" simply renders blank on all emojis.
Text('Google Fonts Kanit',
style: GoogleFonts.kanit(
textStyle: const TextStyle(fontSize: 20),
)),
Text('Google Fonts notoEmoji',
style: GoogleFonts.notoEmoji(
textStyle: const TextStyle(fontSize: 20),
)),
Text('Google Fonts notoColorEmoji',
style: GoogleFonts.notoColorEmoji(
textStyle: const TextStyle(fontSize: 20),
)),
Output:
> [![enter image description here][1]][1]
Is there a fix for it, or another alternative to allow a windows app to render color emojis?
ps: I'm looking for a solution that doesn't involve "hacks" or installing a font in the system, which can mess with other apps.

Use a `BY` statement. The statement will implicitly create automatic flag variables `first.<byvar>` and `last.<byvar>`. When both variables are `=1` the implied condition is that the by group contains a single row. You are looking to flag the inverse condition (when a by group contains more than one row).
```
data want ;
set have ;
by cpt product date ;
flag = not (first.date and last.date) ;
run ;

I am using [this package](https://pub.dev/packages/flutter_pixelmatching) and creating two instances of its class PixelMatching which uses dart ffi and some c++ code to perform feature matching using open cv. I initialise the two instances with different source images with which it compares my camera feed.
However, both of the instances end up using the first image in their comparisons.
Here is where I initialize the matching with two different images.
[initializing the instances](https://i.stack.imgur.com/rhLIa.png)
This is a part of the function where I call the methods to compare the image with my camera stream. The two instances are called alternatively, in one frame the first and in the next the second instance.
[enter image description here](https://i.stack.imgur.com/i5lz9.png)
Am I creating the classes in some wrong way? I don't understand why the two instances can't hold different states. |

I precompile template using this code:
```
func precompileTemplate() {
// Menggunakan template.ParseGlob untuk memuat semua file template
templates = template.Must(template.ParseGlob("static/*.html"))
}
```
In my base.html:
```
<div id="content" class="p-5">
{{template "content" .}}
</div>
```
And in my signup.html
```
{{ define "content" }}
<h1>Signtup to RWID</h1>
{{ end }}
```
In my go route:
```
err = templates.ExecuteTemplate(w, "signup.html", data)
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
}
```
But opening /signup gives me a blank page.

Based on your investigation, I suspect your DB version is older than you think. You could try adding the `ServerVersion.AutoDetect(connectionString)` to your EF core MySql configuration. See if that influences EF core to write SQL that in understandable to your DB version? It would look something like this when you are configuring services:
```
builder.Services.AddDbContext<ApplicationContext>(options =>
{
//...your other configs
var connectionString = builder.Configuration.GetConnectionString("or however you get the connection string...");
options.UseMySql(connectionString, ServerVersion.AutoDetect(connectionString));
});
```
You can also try setting the version explicitly like this:
```
services.AddDbContextPool<YourDbContext>(options => options
.UseMySql(
Configuration.GetConnectionString("how ever you get this"),
mySqlOptions => mySqlOptions.ServerVersion(new Version(10, 0, 40, ServerType.MariaDb)
)
);
```
Use which ever version you have, though |
I am currently trying to build a web app with google apps script, and I have implemented a login function.
The login happens as it should, but I then try to redirect the user to the dashboard of my web app. The current code for the dashboard is the basic code for a new HTML file within apps script with a h1 title, so there are no issues with it.
In my login.html file, this is how it should redirect the user to the dashboard page:
function onLoginSuccess(sessionId) {
if (sessionId) {
console.log('Success')
console.log(sessionId)
window.location.href = "dashboard?sessionId=" + sessionId;
console.log('Success')
} else {
alert("Invalid email or password. Please try again.");
}
}
I have tried an url with `"dashboard.html?sessionId=" +sessionId` and I get the following error in the F12 console: `Failed to load resource: the server responded with a status of 500 ()`
I then tried an url without the html `"dashboard?sessionId=" +sessionId` and I now get the following error: `Refused to display 'https://developers.google.com/' in a frame because it set 'X-Frame-Options' to 'sameorigin'.`
I then tried adding `.setXFrameOptionsMode(HtmlService.XFrameOptionsMode.ALLOWALL);` with my return HtmlService line, but I still get the error.
With both URLs, both success and the session ID get called into the console.
Is there a way to fix the issue? Maybe another way to redirect the user, or just a way to fix the error?

I am making an animated flyout button, it works as intended, I click the button, it slides into position, at the end of the animation it hides and a different button appears in its place with the opposite animation ready waiting to be clicked, this behavior toggles fine. I would like to make clicking anywhere (not solely the second button) trigger moving the second button back.
In the real script a popup window appears, and my intent is to make it dismissible by clicking anywhere outside the window in addition to the button itself. I currently have this working but if the button isnt directly clicked the close animation gets skipped because I cant(don't know how to) trigger it without the button.
I know it's highly likely someone knows how to do this in C#, and I am willing to take examples and figure out how to make a comparable PS codebehind, so I tagged C# too, but if there is a PS method someone knows, that would be extremely helpful.
