Look at this:
for (i = 0; i < N; i += 8)
for (j = 0; j < M; j += 4) {
if (j == i || j == i + 4) { /* same block */
For 8x8 matrix both `N`and `M` is 8 so it's like:
for (i = 0; i < 8; i += 8)
for (j = 0; j < 8; j += 4) {
if (j == i || j == i + 4) { /* same block */
So which values will `i` and `j`take:
i==0, j==0
i==0, j==4
// Now the inner loop ends as j becomes 8 due j+=4
// Now the outer loop ends as i becomes 8 due i+=8
So the `if` statement will only be executed for (i,j) as (0,0) and (0,4). If both cases the `if` condition will be true. As the last statement in the body of the `if` is a `continue`, the code will never reach:
for (i1 = i; i1 < i + 8 ; i1++)
for (j1 = j; j1 < j + 4 ; j1++)
B[j1][i1] = A[i1][j1];
In other words - your algorithm is wrong.

The thing is that I need to create a table and export it as a photo. There are some elements that I need them to be aligned to the right, but I want them to have some margin with respect to the end of the cell. What I did is to convert these numbers to a string, and then I added a blank space at the end (representing the margin)
coste_total = 1234567.89
cadena = "{:,.2f}".format(coste_total)
print(cadena) # Salida: 1,234,567.89
After I do this, I put it in the excel file and add the margin:
ws.append((row[1]['Anyo'], row[1]['Mes'], coste_total + ' ' ,termino_energia + ' ', ter_pot+ ' ', exceso + ' ', resto + ' '))
However, when I do this, and I export the file, I get the corner marked by the control Green Error Checking Markers of Excel, because it detects that the values are numbers, and thus, the exported image has the markers too:
My question is if there is any other way to leave a margin, or if there is a way to ignore these errors via openpyxl. Thanks |

I've looked around a bunch of similarly named questions and am having trouble figuring this out. I'll add that this is my first nextjs project and I've never hosted a website anywhere before.

I read in this post https://stackoverflow.com/questions/58039214/next-js-pages-end-in-404-on-production-build that perhaps it has something to do with having sub-folders inside the pages folder, but I'm not sure how to fix that as I wasn't able to get it to work without sub-foldering page.js files for each page.
Any help would be greatly appreciated! Thanks!

If even after having incorporated the remove icon you still can't see the remove button as happened to me, then, after having implemented all the previous recommendations, make sure that in the module of your component you have imported these four modules:
MatChipGrid,
MatChipRow,
MatChipInput,
MatChipRemove,
But specifically, the one referring to the remove button is: MatChipRemove.
This is the import you should add:
import { NgModule } from '@angular/core';
import {MyComponent} from "./my.component";
import {CommonModule} from "@angular/common";
import {MatButtonModule} from "@angular/material/button";
import {MatFormFieldModule} from "@angular/material/form-field";
import {MatInputModule} from "@angular/material/input";
import {ReactiveFormsModule} from "@angular/forms";

I want to write a script for running regression models across a whole data.table, where my function fits the model and extracts information for later analysis. I have a very large number of models to fit, so I want to make this fast. I want to vectorize this function in order to do this, but have struggled as there are NA values interspersed across the data and I do not want to impute missing values, just fit each model with the data available. I also want to extract a few statistics from the model. So my question is, can this function be vectorized and if so how?
In summary, the aim is to fit a simple linear regression model of the "dependent_var" (first column) versus each of predictor columns (in isolation) using the "covariate" column as a covariate (last column). So from each model, I want the following:
```
return(indepent_var = col,
pearson = cor_coef,
pearson_p = p_value,
indepent_var_beta = slope,
indepent_var_beta_sig = slope_sig,
adj_r_squared = adj_r_squared,
indepent_var_beta_se = se_slope,
intercept_se = se_intercept,
n_obs = nrow(dfx_subset)) # dfx subset being the subset used to fit the model in question.
```
# Toy data
As an example dataset
```
library(data.table)
set.seed(123)
num_rows <- 300
num_cols <- 6000
# Random data
data <- matrix(rnorm(num_rows * num_cols), nrow = num_rows)
# Many columns include NAs which need to be handled during fit without imputation
prop_na <- runif(num_cols, min = 0.1, max = 0.5)
for (i in 1:num_cols) {
num_na <- round(prop_na[i] * num_rows)
idx_na <- sample(1:num_rows, num_na)
data[idx_na, i] <- NA
}
# Mock table, dependent variable and binary covariate variable
DT <- as.data.table(cbind(data, covariate = sample(0:1, num_rows, replace = TRUE)))
setnames(DT, old = c("V1"), new = c("dependent_var"))
```
I may include more covariates in the future, so would like to include Pearson coefficients for some quick checks/potential future analyses. As I have a lot of data to process I'd ideally just submit this once on the HPC. Here is my function so far:
# Linear regression function
```
lm_analysis <- function(col, dfx) {
tryCatch({
dfx_subset <- dfx[complete.cases(dfx[[1]], dfx[[col]], dfx[["covariate"]]), ]
## Compute Pearson correlation
cor_test <- cor.test(dfx_subset[[1]], dfx_subset[[col]])
cor_coef <- cor_test$estimate
p_value <- cor_test$p.value
## Linear regression
lm_result <- lm(dfx_subset[[1]] ~ dfx_subset[[col]] + dfx_subset[["covariate"]], data = dfx_subset)
slope <- lm_result$coefficients[2]
model_summary <- summary(lm_result)
slope_sig <- model_summary$coefficients[2, 4]
adj_r_squared <- model_summary$adj.r.squared
se_slope <- model_summary$coefficients[2, "Std. Error"]
se_intercept <- model_summary$coefficients[1, "Std. Error"]
return(c(indepent_var = col,
pearson = cor_coef,
pearson_p = p_value,
indepent_var_beta = slope,
indepent_var_beta_sig = slope_sig,
adj_r_squared = adj_r_squared,
indepent_var_beta_se = se_slope,
intercept_se = se_intercept,
n_obs = nrow(dfx_subset)))
}, error = function(e){
return(NULL)
})
}
```
# Function application:
```
predictor_cols <- setdiff(names(DT), c("dependent_var", "covariate"))
lm_results <- lapply(predictor_cols, lm_analysis, dfx = DT)
results_lmfit <- as.data.table(do.call(rbind, lm_results))
```
I do not want to filter any observations before the analysis. Also ideally I do not want to parallelise this component as I plan to do this on the outer loop, where I will be performing the above operation on a data.table of dependent variables.
I am at a loose end in terms of how to vectorize this, and due to the mismatching data between different datasets I wasn't sure if this could easily be achievable. Any advice would be appreciated. |

It's a known issue with the latest release, it now has been resolved and the fix will come in the next release. One way to fix it is to rollback to a previous version i.e. 10.7.1 or if the isssue persists like mine you can just add this line of code:

i want to make my extension
I want to suggest "CompletionList" to users.
users can run "editor.action.triggerSuggest"
The process of my extensions as is follows
1. users write some texts
2. if he press "completion command",
3. vscode extension provides Completion
4. and executeCommand("editor.action.triggerSuggest")
But i encounter some issues.
When a specific character is already entered, no matter how much I create CompletionItems, they won't appear unless that specific character is included in the suggestions. For instance, if the cursor is positioned right after the letter 'r' in the word 'for,' the suggestion list won't appear, but if the cursor is one space after 'r,' the suggestion list appears as expected

So, I'm sure this is a bit naive, but this is purely for experimental purposes and/or a learning exercise. In essence, I'd like to see if I can reduce the footprint of the closure created when we use `Task.Run(()=>Func<>())` by creating a class that I initialize only once. One, the objective would be to avoid creating a 'new' instance of this every time we run, which would probably be less efficient than the closure itself I imagine (but this is mere speculation, I know). So, creating a basic class to do so is rather simple, as you can find examples of that here on the stack.
However, where I run into issue, is that it would appear to me, that if I want to use members and functions from another class, that having to encapsulate them, or inject them into the class we're going to `Run` on, while it may be less data than the original class itself, it's probably not going to be that much of an improvement.
So say, I have something along the lines of:
```
internal async Task<PathObject> PopulatePathObjectAsync(Vector3Int origin, Vector3Int destination, PathObject path)
{
return await Task.Factory.StartNew(() => PopulatePathObject(origin, destination, path));
}
/// Not sure if we want to make this a task or not because we may just parallelize and await the outer task.
/// We'll have to decide when we get down to finalization of the architecture and how it's used.
internal PathObject PopulatePathObject(Vector3Int origin, Vector3Int destination, PathObject path)
{
Debug.Log($"Pathfinding Search On Thread: ({System.Threading.Thread.CurrentThread.ManagedThreadId})");
if (!TryVerifyPath(origin, destination, ref path, out PathingNode currentNode))
return path;
var openNodes = m_OpenNodeHeap;
m_ClosedNodes.Clear();
openNodes.ClearAndReset();
openNodes.AddNode(currentNode);
for (int i = CollectionBufferSize; openNodes.Count > 0 && i >= 0; i--)
{
currentNode = ProcessNextOpenNode(openNodes);
if (NodePositionMatchesVector(currentNode, destination))
{
return path.PopulatePathBufferFromOriginToDestination(currentNode, origin, PathState.CompletePath);
}
ProcessNeighboringNodes(currentNode, destination);
}
return path.PopulatePathBufferFromOriginToDestination(currentNode, origin, PathState.IncompletePath);
}
}
```
In order to ditch the lambda, the closure, and the creation (or perhaps cast?) of the delegate, I would need a class that actually encapsulates that `PopulatePathObject` function in its entirety, either by literally copying the members necessary, or passing them as arguments. This all seems like it would probably render any benefits gained. So is there a way I could have something like..
```
private class PopulatePathObjectTask
{
private readonly Vector2Int m_Origin;
private readonly Vector3Int m_Destination;
private readonly PathObject m_Path;
public PopulatePathObjectTask(Vector2Int origin, Vector3Int destination, PathObject path)
{
m_Origin = origin;
m_Destination = destination;
m_Path = path;
}
public PathObject PopulatePathObject(Vector3Int origin, Vector3Int destination, PathObject path)
{
///Obviously here, without access to the actual AStar class responsible for the search,
///I don't have access to the functions or the class members such as the heap or the hashset
///that represents the closed nodes as well as the calculated buffer size based on the space-state
///dimensions. With that, I'd just be recreating the class and not avoiding much, if any,
///of the overhead created by the closure capturing the class in the first place.
}
}
```
That I could use to access the function that already exists? I've been toying with the idea of creating a static member and using dependency injection for the open/closed node collections, but I thought, or rather hoped, someone might have some more insight into this, other than it's pointless and the even *possible* overhead reduction or performance gains will be so minimal that it's pointless. Which, granted you're probably right,but I'm doing this as an exercise and I'd like to be able to actually measure the differences. Quite frankly, I'm probably not even going to use it, might even ditch the AStar for JPS instead, but I would like to know before moving on. Again, just as an exercise of expanding my understanding. I'm not entirely sure, but it would seem as if the closure would have to have the entire AStar object captured in time, one would hope by reference.
Thanks in advanced. Hopefully I don't run into people who leave me seven comments in all caps about how dumb this is and then delete them later and make me look like I'm responding to no one :) |

`Enum` classes (with members) [are final][1], even at runtime, so there is no need to use `Self`. Use `Letter` directly:
<sub>(playground link: [Pyright][2])</sub>
```py
from enum import Enum
class Letter(Enum):
...
@property
def neighbors(self) -> list['Letter']:
match self:
case self.A: # Or `Letter.A`
return [self.B] # Or `Letter.B`
...
```
The behaviour in question is [said][3] to be as designed:
> The `Self` type is effectively a type variable that has an upper bound of the containing class. It is not the same as the class itself.
Also, you can remove the last, wildcard branch:
```py
case _:
# ~
# Pyright will raise an error here since the checking
# done by other branches are already exhaustive.
raise ValueError
```

For this to work you'll need to write a [recursive conditional type](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-4-1.html#recursive-conditional-types) that walks through the [tuple type](https://www.typescriptlang.org/docs/handbook/2/objects.html#tuple-types) of the input array and maps them to another array using the name mapper, and builds up an output by concatenating these arrays.
For example, here's a [tail-recursive conditional type](
https://www.typescriptlang.org/docs/handbook/release-notes/typescript-4-5.html#tail-recursion-elimination-on-conditional-types
) called `MapNames<T, M>` which takes an input tuple `T` and a mapping type `M` that converts the elements of `T` into a new array:
type MapNames<
T extends readonly string[],
M extends Record<T[number], readonly any[]>,
A extends any[] = []
> = T extends readonly [
infer F extends keyof M,
... infer R extends readonly string[]
] ? MapNames<R, M, [...A, ...M[F]]> : A
It uses [variadic tuple types](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-4-0.html#variadic-tuple-types) to manipulate both the input and output tuples. Note that the third type parameter `A` is the *accumulator* and its use makes it tail-recursive and therefore amenable to fairly long input tuples. We break the input tuple `T` into the first element `F` and the rest of the elements `R`. Then `F` is a key of the mapping type `F`, and we concatenate the array `M[F]` to the end of the accumulator, and recurse.
Then you can write a generic `mapNames()` function that takes inputs of types `T` and an `M` and returns a `MapNames<T, M>`:
function mapNames<
const T extends readonly string[],
const M extends Record<T[number], readonly any[]>
>(t: T, m: M): MapNames<T, M> {
return t.reduce<string[]>((acc, e) => {
acc.push(...(m as any)[e]);
return acc;
}, []) as any;
}
This function is implemented the same way as your example, although there's no way for the compiler to understand that the implementation works for such a complicated recursive conditional generic type. So we have to loosen type safety inside the function via [type assertions](https://www.typescriptlang.org/docs/handbook/2/everyday-types.html#type-assertions) and [the `any` type](https://www.typescriptlang.org/docs/handbook/2/everyday-types.html#any), or something like it.
---
Let's test it out:
const t1 = ["a", "b", "c"] as const;
const nameMap = {
"a": [],
"b": ["j"],
"c": ["k", "l"],
} as const;
const t2 = mapNames(t1, nameMap);
// ^? const t2: ["j", "k", "l"]
console.log(t2); // ["j", "k", "l"]
Looks good. The type of `t2` matches the actual value at runtime.

In a Linux shell, a dollar sign `$` inside double quotes gets interpreted as a variable. Since `$1` is undefined, it gets translated into an empty string, so the double-quoted argument effectively becomes:
print if /#define\s+ELFOSABIV_LATEST\s+(\S+)/
when passed to perl, resulting in the entire line being printed when the `if` condition is evaluated as true.
You can remedy it by enclosing the one-liner in single quotes instead to prevent dollar signs from being interpreted by shell:
perl -ne 'print $1 if /#define\s+ELFOSABIV_LATEST\s+(\S+)/' /home/test/elf/elf.h
Note that in Windows you do have to quote arguments with double qoutes, so if you want to maintain just one version of the script you would be better off writing an actual script instead of a one-liner command:
# filter.pl
while (<>) {
print $1 if /#define\s+ELFOSABIV_LATEST\s+(\S+)/;
}
so that:
perl filter.pl /home/test/elf/elf.h
would output `6U` in both platforms.
On the other hand, for your particular use case, you can rewrite your perl code so that it doesn't use any `$` to reference variables, allowing you to use double quotes to enclose the argument on both platforms:
perl -ne "print /#define\s+ELFOSABIV_LATEST\s+(\S+)/" /home/test/elf/elf.h
But again, referencing a variable with a `$` is sometimes unavoidable, in which case you should write it as a separate script to be portable. |

Having a type and a property with the exact same name isn't uncommon. Yes, it looks a little weird, but renaming properties to avoid this clash looks even weirder, admittedly.
Eric Lippert had [a blog post on this exact topic](https://learn.microsoft.com/en-us/archive/blogs/ericlippert/color-color).
There is no ambiguity for the compiler, however. |

I’m fairly new to Python, so go easy on me.
I’m trying to make the following inputs appear at the same time in the console
Input(“Please enter your feet: “)
Input(“Please enter your inches: “)
Desired output:
Please enter your feet:
Please enter your inches:
At the same time for the user to enter.
Whenever I look up how to take multiple inputs at the same time,
I usually get a variation of answers stating to use the split function and to assign the input to two different variables:
x, y = input(“Enter two nums: “)
But I feel that this would be confusing for the user, so I want to be able to prompt them two different entries at the same time on different lines. |

The problem is that you are trying to assign the same ref for all your components. a ref needs to be assined to a single instance of a component so we can modify your code to the following
```
import React, { useRef, useEffect } from "react";
const DynamicComponent = React.forwardRef(({ name }, ref) => {
// Some component logic here...
return <div ref={ref}>{name}</div>;
});
const HOC = ({ dynamicComponentProps }) => {
const dynamicRefs = dynamicComponentProps.map(() => useRef(null));
useEffect(() => {
dynamicRefs.forEach((ref) => {
console.log(ref.current); // This should log the div element
// Some other logic with ref.current...
});
}, [dynamicRefs]);
const renderDynamicComponent = () => {
return dynamicComponentProps.map((props, index) => (
<DynamicComponent ref={dynamicRefs[index]} key={index} {...props} />
));
};
return <div>{renderDynamicComponent()}</div>;
};
const App = () => {
const dynamicComponentProps = [
{ name: "Component A" },
{ name: "Component B" },
{ name: "Component C" },
];
return <HOC dynamicComponentProps={dynamicComponentProps} />;
};
export default App;
```
in this updated version we have a seperate ref foreach component.
to make this work we add to modfiy a few other things as well
1. changed DynamicComponent to forwardRef so that we can pass a ref
2. in the useEffect we log the array of refs
3. in renderDynamiccomponent we assign a different ref to each component
**EDIT**
As pointed out in the comments the above code does break react rule of calling hook in side a loop so we can change the code a little instead of having an array of refs we now have a ref containings an array
```
import React, { useRef, useEffect } from "react";
const DynamicComponent = React.forwardRef(({ name }, ref) => {
// Some component logic here...
return <div ref={ref}>{name}</div>;
});
const HOC = ({ dynamicComponentProps }) => {
const dynamicRefs = useRef(
dynamicComponentProps.map(() => ({ current: null }))
);
useEffect(() => {
dynamicRefs.current.forEach((ref) => {
console.log(ref.current); // This should log the div element
// Some other logic with ref.current...
});
}, [dynamicRefs.current]);
const renderDynamicComponent = () => {
return dynamicComponentProps.map((props, index) => (
<DynamicComponent
ref={dynamicRefs.current[index]}
key={index}
{...props}
/>
));
};
return <div>{renderDynamicComponent()}</div>;
};
const App = () => {
const dynamicComponentProps = [
{ name: "Component A" },
{ name: "Component B" },
{ name: "Component C" },
];
return <HOC dynamicComponentProps={dynamicComponentProps} />;

WSO2 MI 4.2.0
I am using Wso2 micro integrator version 4.2.0. and a rollover policy based on a time period for the log files. I'm trying to delete old rollover files with more than 58 days, meaning that I want to keep ~58 days of logs with the following configuration (as recommended on https://apim.docs.wso2.com/en/latest/administer/logging-and-monitoring/logging/managing-log-growth/):
`appender.CARBON_LOGFILE.strategy.action.type = Delete
appender.CARBON_LOGFILE.strategy.action.basepath = ${sys:carbon.home}/repository/logs/
appender.CARBON_LOGFILE.strategy.action.maxdepth = 1
appender.CARBON_LOGFILE.strategy.action.condition.type = IfLastModified
appender.CARBON_LOGFILE.strategy.action.condition.age = 58D
appender.CARBON_LOGFILE.strategy.action.PathConditions.type = IfFileName
appender.CARBON_LOGFILE.strategy.action.PathConditions.glob = wso2carbon-`
Here is an image of all the configurations I have in log4j.properties for the carbon_logfile:
[log4j config](https://i.stack.imgur.com/Q18l6.png)
But the configuration seems not to be having any effect on wso2carbon log rotation or restart of the service.
The service has 60 files with the pattern wso2carbon-* increasing daily.
[files](https://i.stack.imgur.com/KyuY5.png)
Those anyone come across any similar issues?
Is there something wrong in the configuration for the delete action to be applied? |

Suppose I have a workload that branches out like a tree.
I have to process `n` A items.
Processing each A item requires processing of `m` B items.
This goes on for another level or two.
And I have the following functions:
```go
func handler() {
var aList []A
var wg sync.WaitGroup
for _, a := range aList {
wg.Add(1)
go func () {
defer wg.Done()
processA(a)
}
}
wg.Wait()
}
func processA(a A) error {
var wg sync.WaitGroup
for _, b := range a.BList {
wg.Add(1)
go func () {
defer wg.Done()
processB(b)
}
}
wg.Wait()
}
func processB(b B) error {
var wg sync.WaitGroup
for _, c := range b.CList {
wg.Add(1)
go func () {
defer wg.Done()
processC(c)
}
}
wg.Wait()
}
```
Now the nature of all of theses tasks is that they're BSP (Bulk Synchronous Processses).
By that I mean, that they need **no communication amongst themselves**.
And more importantly, if I had an infinite amount of Cores, there would be **NO** waiting in any thread/goroutine.
Now let's come back to Earth, I am running this on a Lambda function that will have 2/3/4 Cores to offer.
My workload is still such that **no memory limits will be hit**.
Now should I change my code to limit the number of goroutines?
If what I want is speedup?
Is my code lagging due to too much context switching?
Or is there no such thing as "too many goroutines"? |

You can simplify your code to a single `SELECT` (and eliminate the nested loops):
```lang-sql
DECLARE
p_nation STRING_LIST := STRING_LIST('AA', 'BB', 'CC');
p_lastrundate VARCHAR2(20) := '01-JAN-1970 00:00:00';
BEGIN
DBMS_OUTPUT.PUT_LINE('CIDGEN' || '||' || 'NATION');
FOR rec IN (
SELECT B.CIDGEN,
B.NATION
FROM COMPANY B
INNER JOIN NATION_LOOKUP C
ON B.NATION = C.CODE
INNER JOIN TABLE(p_nation) n
ON B.nation = n.COLUMN_VALUE
WHERE B.CIDGEN IN (
SELECT CIDGEN
FROM RAN.OA_REQUEST_RESPONSE_STATUS
WHERE RESPONSE_STATUS = 'FailedRequest'
AND RESPONSE_UPDATE_STAMP >=
TO_DATE(p_lastrundate, 'DD-MON-YYYY HH24:MI:SS')
)
)
LOOP
DBMS_OUTPUT.PUT_LINE(rec.CIDGEN || '||' || rec.NATION);
END LOOP;
END;
/
```
Which, for the sample data:
```lang-sql
CREATE TABLE company (cidgen, nation) AS
SELECT 'Acme Corporation', 'AA' FROM DUAL UNION ALL
SELECT 'Octan', 'CC' FROM DUAL UNION ALL
SELECT 'Umbrella Corporation', 'BB' FROM DUAL UNION ALL
SELECT 'Wayne Enterprises', 'BB' FROM DUAL;
CREATE TABLE nation_lookup (code) AS
SELECT 'AA' FROM DUAL UNION ALL
SELECT 'BB' FROM DUAL UNION ALL
SELECT 'CC' FROM DUAL;
CREATE TABLE RAN.OA_REQUEST_RESPONSE_STATUS (cidgen, response_status, response_update_stamp) AS
SELECT 'Acme Corporation', 'FailedRequest', SYSDATE FROM DUAL UNION ALL
SELECT 'Octan', 'FailedRequest', SYSDATE FROM DUAL UNION ALL
SELECT 'Umbrella Corporation', 'FailedRequest', SYSDATE FROM DUAL UNION ALL
SELECT 'Wayne Enterprises', 'FailedRequest', SYSDATE FROM DUAL
CREATE TYPE string_list IS TABLE OF VARCHAR2(200);
```
Outputs:
``` status

There is a QLabel added to the statusbar of the main window. When setting long text, the QLabel expands and expands the window with it. It is necessary that the size of the QLabel and the window do not change, and only the text that fits is shown (as happens with a fixed size widget). The width of the QLabel cannot be set to a fixed, because it must change depending on the width of the window. Probably there are some size policy settings for widgets?

I am using Masstransit version 7.3.1 and rabbitmq to create a messaging mechanism (I am sending a message with each request the API receives) and I installed the Greenpipes library to use it later but after some monitoring I found out that Greenpipes is using a lot of CPU (see the image).
Does Masstransit use Greenpipes? And why is Greenpipes' CPU usage so high even though I am not using it directly?

After the suggestion from @rcgldr I modified the solution. the solution is not really functional way of doing things but at least it runs within the specified time.
*One thing to note is that if you submit the same answer at different times of day **OR** repeatedly submit the same solution, you get different tests failing due to timeout. A bit strange! (must be a flaw in their system) and depending on your luck all tests are passed.*

I want to sort the values of this dictionary from low to high:
For example,
input:
```
average = {'ali': 7.83, 'mahdi': 13.4, 'hadi': 16.2, 'hasan': 3.57}
```
I want the output to be like this:
```
{'hasan': 3.57, 'ali': 7.83, 'mahdi': 13.4, 'hadi': 16.2}
```
I tested this method, but because my data is decimal, it gives an error:
```
dict(sorted(average.items(), key=lambda item: item[1]))
```
Error:
```
ave_dict_sort = dict(sorted(average.items(), key=lambda item: item[1]))
^^^^^^^^^^^^^
AttributeError: 'float' object has no attribute 'items'

I have a web application (4.8 Framework API) and I need to be able to test on local machine with various settings and I do not want them accidentally checked into source code repository.
For example, Web.Config would have our standard settings but my Web.Local.Config would have settings I may need to debug a client's problem. It would be marked as "ignored" for the purposes of git commits.
I installed the SlowCheetah extension and nuget but that does not seem to work. When testing, the transform is not being performed. The value in the web.config is shown on the page. The transformonbuild is not showing in the project file.
I am even open to adding a post build script.

I'm using the apphud sdk to fetch in app purchase products. The SDK is used to purchase products in an IOS app. I use the following code
Apphud.paywallsDidLoadCallback { paywalls in
if let paywall = paywalls.first(where: { $0.identifier == "your_paywall_id" }) {
I get the following error
Cannot pass function of type '([ApphudPaywall]) async -> Void' to parameter expecting synchronous function type
paywallsDidLoadCallback is defined as
@MainActor
@objc public static func paywallsDidLoadCallback(_ callback: @escaping ([ApphudPaywall]) -> Void) {
ApphudInternal.shared.performWhenOfferingsReady {
callback(ApphudInternal.shared.paywalls)
}
}
is this because the apphud sdk does not support async/await? Since this is a third party sdk, is there a quick fix? Please help! |

The problem was that in my Users table in the database, the email field had a capital 'E' like 'Email.' However, Laravel by default searches for 'email' with a lowercase 'e,' and that's why.
If you don't want to modify the column's name on your database you can paste the following code on your User's model:
public function getEmailForPasswordReset(): string
{
return $this->Email;
}
This code will overwrite the getEmailForPasswordReset on your User's model and you can customize the field that's going to be researched. Hope it helps some lost soul like mine! |

I don't know if I did it right, but I found a solution to make it work the way I want. Based on the answer here https://stackoverflow.com/a/67083089/21533506 I added the following code:
```
add_filter( 'woocommerce_package_rates', 'disable_shipping_method_based_on_location', 10, 2 );
function disable_shipping_method_based_on_location( $rates, $package ) {
$city = $package['destination']['city'];
// If the city is Paris, hide flat_rate:2, flat_rate:4 and local_pickup:3
if ( 'Paris' === $city ) {
unset( $rates['flat_rate:2'] );
unset( $rates['flat_rate:4'] );
} else { // Otherwise, hide flat_rate:6, flat_rate:7 and local_pickup:3 for all other localities
unset( $rates['flat_rate:6'] );
unset( $rates['flat_rate:7'] );
unset( $rates['local_pickup:3'] );
}
return $rates;
```
After that I added the following code to hide all delivery methods until the address is filled in:
```
add_filter('woocommerce_package_rates', 'hide_shipping_until_address');
function hide_shipping_until_address($rates) {
$address = WC()->customer->get_shipping();
$city = isset($address['city']) ? $address['city'] : '';
$state = isset($address['state']) ? $address['state'] : '';
if (empty($city) || empty($state)) {
foreach ($rates as $rate_id => $rate) {
unset($rates[$rate_id]);
}
}
return $rates;
}
```
After that I modified the code from here https://stackoverflow.com/a/77896304/21533506 to display the local fetch in the first position:
```
add_filter( 'woocommerce_package_rates', 'filter_woocommerce_package_rates', 100, 2 );
function filter_woocommerce_package_rates( $rates, $package ) {
$free_shipping_exists = false; // Initialize free shipping flag
// Loop through shipping rates for the current shipping package
foreach ( $rates as $rate_key => $rate ) {
// If method is free shipping, set free shipping flag to true
if ( 'free_shipping' === $rate->method_id ) {
$free_shipping_exists = true;
break;
}
}
// If free shipping exists, hide other shipping methods except local pickup
if ( $free_shipping_exists ) {
foreach ( $rates as $rate_key => $rate ) {
// If method is not local pickup and not free shipping, unset it
if ( 'local_pickup' !== $rate->method_id && 'free_shipping' !== $rate->method_id ) {
unset( $rates[$rate_key] );
}
// If method is local pickup, set cost to zero
elseif ( 'local_pickup' === $rate->method_id ) {
$rates[$rate_key]->cost = 0;
$rates[$rate_key]->taxes = array_fill_keys( array_keys( $rates[$rate_key]->taxes ), 0 );
}
}
}
return $rates;
}

I am working on a virtualised data grid for my application.
I use transform: translateY for the table offset on scroll to make table virtualised.
I developed all the functionality in React 17 project, but when migrated to React 18 I found that the data grid behaviour changed for the worse - the data grid started to bounce on scroll.
I prepared the minimal representing code extract, which shows my problem.
To assure that the code is the same for React 17 and React 18, I change only the import of ReactDOM from 'react-dom/client' to 'react-dom' (which is of course incorrect, since the latter is deprecated) in my index.tsx file.
This is the code:
index.html
```
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Virtuailsed table</title>
</head>
<body>
<noscript>You need to enable JavaScript to run this app.</noscript>
<div id="root"></div>
</body>
</html>
```
index.js
```
// import ReactDOM from "react-dom";
import ReactDOM from "react-dom/client";
import { useState } from "react";
import "./styles.css";
let vendors = [];
for (let i = 0; i < 1000; i++ ){
vendors.push({
id: i,
edrpou: i,
fullName: i,
address: i
})
}
const scrollDefaults = {
scrollTop: 0,
firstNode: 0,
lastNode: 70,
};
function App() {
const [scroll, setScroll] = useState(scrollDefaults);
const rowHeight = 20;
const tableHeight = rowHeight * vendors.length + 40;
const handleScroll = (event) => {
const scrollTop = event.currentTarget.scrollTop;
const firstNode = Math.floor(scrollTop / rowHeight);
setScroll({
scrollTop: scrollTop,
firstNode: firstNode,
lastNode: firstNode + 70,
});
};
const vendorKeys = Object.keys(vendors[0]);
return (
<div
style={{ height: "1500px", overflow: "auto" }}
onScroll={handleScroll}
>
<div className="table-fixed-head" style={{ height: `${tableHeight}px` }}>
<table style={{transform: `translateY(${scroll.scrollTop}px)`}}>
<thead style={{ position: "relative" }}>
<tr>
{vendorKeys.map((key) => <td>{key}</td>)}
</tr>
</thead>
<tbody >
{vendors.slice(scroll.firstNode, scroll.lastNode).map((item) => (
<tr style={{ height: rowHeight }} key={item.id}>
{vendorKeys.map((key) => <td><div className="data">{item[key]}</div></td>)}
</tr>
))}
</tbody>
</table>
</div>
</div>
);
}
// const rootElement = document.getElementById("root");
// ReactDOM.render(<App />, rootElement);
const root = ReactDOM.createRoot(
document.getElementById('root')
);
root.render(
<App />
);
```
styles.css
```
* {
padding: 0;
margin: 0
}
.table-fixed-head thead th{
background-color: white;
}
.row {
line-height: 20px;
background: #dafff5;
max-width: 200px;
margin: 0 auto;
box-shadow: 0 0 1px 0 rgba(0, 0, 0, 0.5);
}
.data{
width: 150px;
white-space: nowrap;
overflow: hidden;
margin-right: 20px;
}
```
I have spent 1.5 day trying to find the reason why the table bounces on scroll in React 18 without result.
BTW, overscroll-behaviour: none doesn`t work. |
