When I open the "recently opened file" tab in MS word, I see that each file is marked with a green check:
[![enter image description here][1]][1]
The green check sign is usually used to indicate a file is uploaded and synced with cloud. But I never turned on any cloud sync, my onedrive app is not logined in.
[![enter image description here][2]][2]
Does it mean MS-word secrectly upload my doc anywhere?

Use below procedure.
1. Give your elements unique ids.
Like
```html
<div id="tab1"></div>
<div id="tab2"></div>
<div id="tab3"></div>
<div id="tab4"></div>
```
2. Give your urls tab id, that you need to focus
```python
url_path#tab2
```
3. Use js to focus tab with id from url
```javascript
document.getElementById(window.location.hash).click();
``` |

1. Return a pointer to the `Node` of interest instead of updating the out parameter `head_dest`. The stack will implicitly hold `cur_list_dest`.
1. The original implementation changes the original list. To create a new list you need to return a pointer to *copy* of the smallest node or NULL. To emphasize that I made the argument constant with `const Node *head`.
1. Finally, you can optimize the implementation of `pairWiseMinimumInNewList_Rec()` by observing that we return either a copy of the first or 2nd node or NULL (base case). The recursive call is either two nodes ahead or we are done:
```
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
typedef struct Node {
int val;
struct Node *pt_next;
} Node;
Node *linked_list_new(int val, Node *pt_next) {
Node *n = malloc(sizeof *n);
if(!n) {
printf("malloc failed\n");
exit(1);
}
n->val = val;
n->pt_next = pt_next;
return n;
}
Node *linked_list_create(size_t n, int *vals) {
Node *head = NULL;
Node **cur = &head;
for(size_t i=0; i < n; i++) {
*cur = linked_list_new(vals[i], NULL);
if(!head) head = *cur;
cur = &(*cur)->pt_next;
}
return head;
}
void linked_list_print(Node *head) {
for(; head; head=head->pt_next)
printf("%d->", head->val);
printf("NULL\n");
}
void linked_list_free(Node *head) {
while(head) {
Node *tmp = head->pt_next;
free(head);
head=tmp;
}
}
Node *pairWiseMinimumInNewList_Rec(const Node* head) {
if(!head)
return NULL;
return linked_list_new(
(head->pt_next && head->val < head->pt_next->val) ||
(!head->pt_next) ?
head->val :
head->pt_next->val,
pairWiseMinimumInNewList_Rec(head->pt_next ? head->pt_next->pt_next : NULL)
);
}
int main() {
Node *head=linked_list_create(7, (int []) {2,1,3,4,5,6,7});
Node* head_dest=pairWiseMinimumInNewList_Rec(head);
linked_list_free(head);
linked_list_print(head_dest);

I'm currently working on a VHDL project involving a finite state machine (FSM) that transitions through three states (STATE_0, STATE_1, and STATE_2) based on an external signal T. Each state should wait for a certain number of pulses from T before transitioning to the next state.
The behavior I'm expecting is as follows:
When in STATE_0, the FSM should transition to STATE_1 after receiving 2 pulses from T.
When in STATE_1, it should transition to STATE_2 after receiving 4 pulses.
When in STATE_2, it should transition back to STATE_0 after receiving 6 pulses.
However, my FSM implementation doesn't seem to be behaving correctly. It's not transitioning states as expected, and I suspect there might be issues with how I'm handling the counter and state transitions.
I've provided the VHDL code below, along with a waveform file from my simulation (used Quartus II 9.0 web edition). The code compiles correctly.
Take into account I am a complete beginner in VHDL and this is my first question in Stack Overflow, so any feedback on how to better the way I ask questions will be highly appreciated.

entity STLC is
Port (
clk, T : in STD_LOGIC;
state_out : out STD_LOGIC_VECTOR(1 downto 0)
);
end entity STLC;
architecture Behavioral of STLC is
type state_type is (STATE_0, STATE_1, STATE_2);
signal current_state, next_state : state_type;
signal counter : integer range 0 to 63 := 0; -- Inner counter to track state durations
signal B : integer range 0 to 63 := 0;
begin
state_transition_process: process(current_state, counter)
begin
case current_state is
when STATE_0 =>
if counter - B > 2 then
next_state <= STATE_1;
B <= counter; -- Reset counter
else
next_state <= STATE_0;
end if;
when STATE_1 =>
if counter - B > 4 then
next_state <= STATE_2;
B <= counter; -- Reset counter
else
next_state <= STATE_1;
end if;
when STATE_2 =>
if counter - B > 6 then
next_state <= STATE_0;

next_state <= STATE_2;
end if;

next_state <= STATE_0;
end case;
end process;

end process output_logic;

[Updated simulation after adding B to sensitivity list][1]
Could someone please review my code and provide guidance on what might be causing this issue? Any help would be greatly appreciated. Thank you!
I've implemented a finite state machine in VHDL, specifying the transitions between states based on the number of pulses received from the external signal T. I've coded the logic for each state transition and initialized counters to track the number of pulses. However, despite my efforts, the FSM isn't transitioning states as expected. I expected the FSM to transition from STATE_0 to STATE_1 after 2 pulses, from STATE_1 to STATE_2 after 4 pulses, and from STATE_2 back to STATE_0 after 6 pulses.

If you need the main `ScrollView` or `List` to display another horizontal list or lists there is very good trick to make the performance perfect, just wrap each of your horizontal collections with `Section` like this:
```
Section {
//horizontal collection here
}
``` |
I'm encountering an issue in my Vue application where the use of functional components within a table leads to entire re-renders of all cells when any cell's value changes, triggering a backend request and subsequently updating a list of cells based on the response. However, when I switch to using stateful template components for these cells, only the affected cell re-renders upon update.
Environment:
- Vue 2.7, Webpack 5.11
Problem Detail:
My table component renders each cell as a separate component. The table includes column aggregators, and cell value changes initiate a backend request. The response dictates which cells to update. Using functional components for these cells results in the entire table re-rendering, but switching to standard stateful template components limits the re-render to only the changed cell.
```
// table.vue
<tr v-for="row in cells" :key="row[0].id">
<TableCellHeader />
<TableCell v-for="(cell, idx) in row.slice(1)"
:key="row[0].data.id+'_'+idx"
:cell="cell"
:col-index="idx+1"
:row-id="row[0].id"
:disable="isDisabled(row[0], cell, idx+1)"
@saved="save" />
</tr>
```
```

let element;
// some other class like validation before request
let setClass = (className) => {
if (!element) return;
let classNames = ['error', 'saved', 'saving'];
classNames.forEach((name) => {
element.classList.remove(name);
});
if (!className) return;
element.classList.add(className);
};
let save = (updatedValue, cell, rowId) => {
// post to server
updateValue(updatedValue)
.then((result) => {
setClass('saved');
setTimeout(() => {
setClass('');
}, 3000);
listeners.saved?.(result);
})
.catch(e => {
setClass('error');
});
};
let onFocusOut = (event) => {
element = event.target.closest('td');
let updatedValue = event.target.innerText.trim();
setClass('saving');
event.target.innerHTML = dompurify.sanitize(updatedValue);
save(updatedValue, props.cell, props.rowId);
};
return h('td', {
class: [$style.cell, 'spo-table-cell'],
attrs: {
'data-disabled': props.disable,
},
}, [
h(Stack, {
props: {

[Performance of update. Function createFunctionalComponent has been called 802 times](https://i.stack.imgur.com/MJtFi.png)
What could be causing this discrepancy in re-render behavior between functional components and stateful components in Vue? How can I ensure that only the updated cells re-render in the table when using functional components, similar to the behavior observed with stateful template components? |
I have a circle that follows my curser and I also made it expand when I hover over any text. The problem is when I try to add a `transition: 2s;` to the CSS to make it expand smoothly. it ruins my JavaScript animation so I was wondering if I could add only a transition time to when the the circle expands.

I'm trying to understand the differences between the `mov` and `lea` instructions in x86 assembly language. I've written a simple assembly code snippet , and I've added comments to explain my understanding of these instructions.
```x86asm
.data
num: .int 2 # Declare an integer variable num with value 2
.text
.globl _start
_start:
movl num, %eax # num stores an address, take the value inside that address into eax
movl $num, %ebx # num stores an address, $ tells us to take the address itself into ebx
leal num, %ecx # num stores an address, take the address itself into ecx (lea)
#initialize
movl $0, %eax
movl $0, %ebx
movl $0, %ecx
movl $num, %edx # num stores an address, take the address itself into edx
movl %edx, %eax # edx is an address, take the value inside that address into eax
leal (%edx), %ecx # () tells us to go to the address inside edx, take the address itself into ecx (lea)
movl (%edx), %ebx # () tells us to go to the address inside edx, take the value inside that address into ebx
# Exit
movl $1, %eax # System call number for exit
xorl %ebx, %ebx # Exit status 0
int $0x80 # Invoke the syscall
```
However, I'm a bit confused about how these instructions work with registers. and I'll be glad if someone will give me his explanation.

I am a beginner trying to build very simple inventory system using PHP + SQL
I have 2 warehouse. I added 2 tables, 1 for each warehouse contains (item id)-(in)- (out) like shown below
table1
| item id | in | out |
| -------- | -- |-----|
| item1 | 10 | 0 |
| item1 | 5 | 0 |
| item2 | 0 | 3 |
| item2 | 0 | 2 |
table2
| item id | in | out |
| -------- | -- |-----|
| item1 | 12 | 0 |
| item1 | 50 | 0 |
| item2 | 0 | 10 |
| item2 | 0 | 30 |
I have report show balance for each warehouse separately by using query below
`Select item_id, sum(in-out) as balance from table1 group by item_id`
My question is how show each warehouse balance in one table like below
| item id | warehouse1 | warehouse2|
| -------- | ---------- |-----------|
| item1 | 7 | 2 |
| item2 | 3 | 20 |
I tired with this query but I get wrong results
`SELECT table1.item_id, sum(table1.in)-sum(table1.out) as tb1, sum(table2.in)-sum(table2.out) as tb2 FROM table1 , table2 WHERE table1.item_id=table2.item_id GROUP by item_id`

I have 1 parent(Container) and 2 (List, SelectedItem) child components, Initially I render all data to Container and send all data to list and first item as selectedItem to selected Item component. So ar so good
When a user clicks an item in the List component, it updates the selected item of the Parent through a function, the parent is able to update state, But it is not re-rendering selected item component.
List Component:
```
import "./SelectedImage.css"
function ListSection({items, updateSelectedItem}) {
return (
<div className="list-section">
<ul>
{
(items).map((item) => {
return <li key={item.id} onClick={() => updateSelectedItem(item.id)}>{item.name}</li>
})
}
</ul>
</div>
);
}
export default ListSection;
```
Container Component
```
import LeftSection from './LeftSection';
import logo from './logo.svg';
import RightSection from './RightSection ';
import SelectedItem from './SelectedItem';
import "./App.css";
import ListSection from './ListSection';
import { Component, useState } from 'react';
const products = [
{id: 1, name: "Lime", size: ["large", "medium", "small"], category: "Juice", image: "lime-juice.jpg"},
{id: 2, name: "Orange", size: ["large", "medium", "small"], category: "Juice", image: "orange-juice.jpg"},
{id: 3, name: "Mango", size: ["large", "medium", "small"], category: "Juice", image: "mango-juice.jpg"},
]
function Container() {
let [selectItem, setSelectItem] = useState(products[0]);
function chooseSelectedItem(id) {
let item = products.filter((value) => {
console.log(value.id);
return (value.id == id)
})
setSelectItem(item[0]);
console.log(item[0]);
}
return (
<div className="Container">
<ListSection items={products} updateSelectedItem={chooseSelectedItem}/>
<SelectedItem CurrentSelectedItem={selectItem}/>
</div>
);
}
export default Container;
```
SelectedItemComponent
```
import QuantityBar from "./QuantityBar";
import "./SelectedImage.css"
import { useState } from "react";
function SelectedItem({CurrentSelectedItem}) {
let [item, setItem] = useState(CurrentSelectedItem);
return (
<div className="selected-item">
{/* <img src={item.image} className="selected-image" /> */}
{item.name}
{/* <QuantityBar itemCount={0} /> */}
</div>
);
}
export default SelectedItem;

I am using an ASP.NET Core Web API with Entity Framework Core (pomelo). I have a MariaDB database. I use Swagger UI to explore my API, as per the template. When I try to use it to delete a row, I get the following error:

The delete should be handled here in my controller and repository, like this:
[HttpDelete("alertId")]
public async Task<IActionResult> DeleteAlert(int alertId)
{
var alert = await _dataRepository.GetAlertAsync(alertId);
if (alert is null)
{
return NotFound("Alert not found");
}
await _dataRepository.DeleteAlertAsync(alert);
return NoContent();
}
and this
public class AlertRepository (IrtsContext context) : IDataRepositoryAlerts
{
readonly IrtsContext _alertContext = context;
public async Task DeleteAlertAsync(Alert entity)
{
if (entity != null)
{
_alertContext.Remove(entity);
await _alertContext.SaveChangesAsync();
}
else
{
throw new NotImplementedException();
}
}
}
I do not understand this. I believe it is my `dbContext` that handles the "saving the entity changes". How can I have a SQL syntax error? I cannot find "Returning 1" anywhere in my code.
I have tried deleting the row manually in my database. That works.
All other operations (GET, POST and PUT) work just fine.
I have tried running this with holding points to see where the error occurs but everything seems to execute without issue.
I am grateful for any hints. I am obviously very new to this ;)
Edit: MariaDB version 11.2.2
Edit2: This is my Alert class:
public partial class Alert
{
public int AlertId { get; set; }
public DateTime? Zeitpunkt { get; set; }
public string? Quelle { get; set; }
public string? AlertStatus { get; set; }
public string? AlertTyp { get; set; }
public string? BetroffeneSysteme { get; set; }
public virtual ICollection<Vorfall> Vorfalls { get; set; } = new List<Vorfall>();
}
and this is its entity configuration:
modelBuilder.Entity<Alert>(entity =>
{
entity.HasKey(e => e.AlertId).HasName("PRIMARY");
entity
.ToTable("alert")
.HasCharSet("utf8mb4")
.UseCollation("utf8mb4");
entity.Property(e => e.AlertId)
.HasColumnType("int(11)")
.HasColumnName("AlertID");
entity.Property(e => e.AlertStatus).HasMaxLength(255);
entity.Property(e => e.AlertTyp).HasMaxLength(255);
entity.Property(e => e.BetroffeneSysteme).HasMaxLength(255);
entity.Property(e => e.Quelle).HasMaxLength(255);
entity.Property(e => e.Zeitpunkt).HasColumnType("datetime");
});
edit3: I found the parameterized query. It goes thus:
[The error in the log with sql query]
Edit 4: copying the query into workbench gives the following error:
[![sql][1]][1]
It appears that the problem really is the "RETURNING 1" and I must admit I have no idea what it is for. Is there a way to remove it? I have found no way to edit the EF queries themselves. Alternatively I might need to try a different database.
Thank you for your help!

I don't really understand why you are messing around with central directories and building the Zip manually. None of this is necessary as you can use `ZipArchive` to do this in one go.
Furthermore, you can't compress chunks of bytes like that and then just concatenate them. The Deflate algorithm doesn't work that way.
Your concern about flushing is misplaced: if the `ZipArchive` is closed then everything is flushed. You just need to make it leave the stream open once you dispose it.
I would advise you to only work with `Stream`, but you could use `byte[]` or `Memory<byte>` if absolutely necessary.
```cs
public async Task<Memory<byte>> Compress(string fileName, IAsyncEnumerable<Memory<byte>> data)
{
var ms = new MemoryStream();
using (var zip = new ZipArchive(ms, ZipArchiveMode.Create, leaveOpen: true))
{
var entry = zip.CreateEntry(fileName);
using var zipStream = entry.Open();
await foreach (var bytes in data)
{
zipStream.Write(bytes);
}
}
return new ms.GetBuffer().AsMemory(0, (int)ms.Length);

I'm on a mac and trying to run a local Postgres database with the PostGIS extension, and then populate the database with a shapefile, without having to load the data in manually.
I have a ```docker-compose.yml``` where I'm first using the postgis docker image and using port 5432. I've already tested this when the container is running and I can successfully connect.
The second part, ```import-shapefile``` uses the postgres image and installs the needed extensions, converts the shapefile and should add the results into the db running in the postgis container.
docker-compose.yml:
```
services:
postgis:
image: postgis/postgis
restart: always
env_file:
- .env
ports:
- 5432:5432
platform: linux/amd64
volumes:
- ./dataset:/dataset
import-shapefile:
image: postgres
depends_on:
- postgis
volumes:
- ./dataset:/dataset
entrypoint: sh
command: -c "apt-get update && apt-get install -y postgis && shp2pgsql -s 4326 -I -D -W UTF-8 dataset/my_shapefile.shp my_table | psql -U username -d my_db"
environment:
- POSTGRES_USER
- POSTGRES_DB
```
When looking at the container logs I see the error in the import-shapefile container:
```
sql: error: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: No such file or directory
Is the server running locally and accepting connections on that socket?

I have been searching for whole day, yet couldn't find a valid solve to this annoying problem.

I tried to change my port, add different routing syntax. I am currently using visual studio 2022 and my project is .NET 8.0
PS: My problem only occurs when I need to go to the pages of Admin. |

I'm using template haskell to include content from non-Haskell files in some of my code, and this content is then parsed and used. The problem that I have with using `cabal` as a build tool for this is that it doesn't detect when these files changes and so I find myself using `cabal clean; cabal build` which forces the _whole_ project to be rebuilt (including some dependencies) which is slower than it could otherwise be. |
You could use [`top_k`](https://docs.pola.rs/py-polars/html/reference/dataframe/api/polars.DataFrame.top_k.html) and slice the last row:
```
import polars as pl
np.random.seed(0)
df = pl.DataFrame({'col': np.random.choice(5, size=5, replace=False)})
out = df.top_k(2, by='col')[-1]
```
You could also [`filter`](https://docs.pola.rs/py-polars/html/reference/dataframe/api/polars.DataFrame.filter.html) with [`rank`](https://docs.pola.rs/py-polars/html/reference/expressions/api/polars.Expr.rank.html), but this will perform a full sort, so it could be algorithmically less efficient:
```
out = df.filter(pl.col('col').rank(descending=True)==2)
```
Or with [tag:numpy]'s [`argpartition`](https://numpy.org/doc/stable/reference/generated/numpy.argpartition.html):
```
out = df[int(np.argpartition(df['col'], -N)[-N])]
```
Output:
```

In stripe I have 2 products.
Monthly subscription ($50 for beginner).
Monthly subscription ($70 for advanced).
The user (a parent) can complete a form "Add student to courses". The result is creating tabs with content specific for each kid they sign up to classes.
If the user pays a subscription for each kid, in my supabase "subscriptions" table, a column student_id will be populated with the student's id that is the foreign key to a students table.
So the parent can have multiple subscriptions for each of his/her kids.
Problem: Let's say both kids are beginners for the classes. If I go to stripe customer portal from the parent's page, I will have 2 subscriptions, both named "Monthly subscription".
How can I differentiate between the 2? Something like "Monthly Subscription for Hannah" and "Monthly Subscription for Paul"
It looks like I can only create one customer portal, but then all I can see are 2 subscriptions "Monthly Subscription" |
Need some advice on differentiating between subscriptions using Stripe |

i have this page component for each product information:
```
export default function Product() {
const { data } = useContext(ShopContext);
const { id } = useParams();
if (!data) {
return <div>Loading product...</div>;
}
const product = data.find((item) => item.id === id);
return (
<div>
{product.title}
</div>
);
}
```
somehow product is undefined though data and id can be logged into console and their value is available, i made sure of it like this:
```
export default function Product() {
const { data } = useContext(ShopContext);
const { id } = useParams();
if (!data) {
return <div>Loading product...</div>;
}
return (
<div>
<div>{id}</div> {/*this div is displayed as expected*/}
<div> {/*this div is displayed as expected*/}
{data.map((item) => (
<div key={item.id}>{item.title}</div>
))}
</div>
<div>{product?.title}</div> {/*this div is empty*/}
</div>
);
}
```
i really can't find a solution when i even don't understand what's going on but i did it this way too and still nothing on the page (the url is correct and loading div is displayed):
```
export default function Product() {
const { data } = useContext(ShopContext);
const { id } = useParams();
if (!data) {
return <div>Loading product...</div>;
}
return (
<div>
{data.map(item => (
<div key={item.id}>
{item.id === id ? item.title : null}
</div>
))}
</div>
);
}
```
for additional information i'm fetching the data from [fakestoreapi.com](fakestoreapi.com) in the app component and it works fine in other components. here's the fetching piece:
```
useEffect(() => {
async function FetchData() {
try {
const response = await fetch("https://fakestoreapi.com/products");
if (!response.ok) {
throw new Error(`HTTP error: Status ${response.status}`);
}
let postsData = await response.json();
postsData.sort((a, b) => {
const nameA = a.title.toLowerCase();
const nameB = b.title.toLowerCase();
return nameA.localeCompare(nameB);
});
setData(postsData);
setError(null);
} catch (err) {
setData(null);
setError(err.message);
} finally {
setLoading(false);
}
}
FetchData();
}, []);
```
this is the context:
```
import { createContext } from "react";
export const ShopContext = createContext({
data: [],
loading: true,
error: "",
setData: () => {},
cart: [],
addToCart: () => {},
removeFromCart: () => {},
});
```
and this is its states in app component:
```
const [data, setData] = useState(null);

How to make a linear graph plotting gene counts on y axis and gene lengths on x? |
|r|ggplot2|histogram| |
Please I am very new to flutter. I am working on a project and i got stuck in the implementation. I was wondering if you can help out. I am creating an audiobook. It converts pdf to audiofiles. I created a list of the books on a screen and if you tap on a book, it should list out the audios associated with it. Now the problem is that I split the audios into different parts as seen below:
```
import 'package:audioplayers/audioplayers.dart';
import 'package:flutter/material.dart';
import 'audio.dart';
class Audios with ChangeNotifier {
final List<Audio> _audios = [
Audio(
audioId: 1,
bookId: 1,
userId: 1,
audioFile: [
"https://myaudiobookapp.s3.eu-central-1.amazonaws.com/the_frog_prince_part1.mp3",
"https://myaudiobookapp.s3.eu-central-1.amazonaws.com/the_frog_prince_part2.mp3",
"https://myaudiobookapp.s3.eu-central-1.amazonaws.com/the_frog_prince_part3.mp3"
],
audioName: "the_frog_prince",
bookImage:
"https://myaudiobookapp.s3.amazonaws.com/1_The-Frog-Prince-Landscape-Book-CKF-FKB.pdf.png"),
Audio(
audioId: 2,
bookId: 2,
userId: 1,
audioFile: [
"https://myaudiobookapp.s3.amazonaws.com/sara_menker_part1.mp3"
],
audioName: "sara_menker",
bookImage:
"https://myaudiobookapp.s3.amazonaws.com/Data_Analysis_Plan_of_Sara_Menker.pdf.png",
),
];
// current song playing index
int? _currentAudioIndex;
/*
A U D I O P L A Y E R
*/
// audio player
final AudioPlayer _audioPlayer = AudioPlayer();
// durations
Duration _currentDuration = Duration.zero;
Duration _totalDuration = Duration.zero;
// constructor
Audios() {
listenToDuration();
}
// initially not playing
bool _isPlaying = false;
// play the audio
void playAudio(int index) async {
// final audIndex = _audios.indexWhere((aud) => aud.audioId == index + 1);
int i = 0;
while (i < _audios[index].audioFile.length) {
final audioUrl = _audios[index].audioFile[i];
await _audioPlayer.stop();
await _audioPlayer.play(audioUrl);
_isPlaying = true;
_currentAudioIndex = index;
notifyListeners();
}
}
// pause current song
void pauseAudio() async {
await _audioPlayer.pause();
_isPlaying = false;
notifyListeners();
}
// resume playing
void resumeAudio() async {
await _audioPlayer.resume();
_isPlaying = true;
notifyListeners();
}
// pause or resume
void pauseOrResumeAudio() async {
if (_isPlaying) {
pauseAudio();
} else {
resumeAudio();
}
notifyListeners();
}
// seek to a specific position in the current audio
void seek(Duration position) async {
await _audioPlayer.seek(position);
}
// play next song
void playNextAudio() {
if (_currentAudioIndex != null) {
if (_currentAudioIndex! < _audios.length - 1) {
// go to the next audio if it's not the last audio
currentAudioIndex = _currentAudioIndex! + 1;
} else {
// if it's the last song, loop back to the first song
currentAudioIndex = 0;
}
}
}
// play previous song
void playPreviousAudio() {
// if more than 2 seconds have passed, restart the current audio
if (_currentDuration.inSeconds > 2) {
// if it's within first 2 second of the audio, go to previous song
seek(Duration.zero);
} else {
if (_currentAudioIndex! > 0) {
currentAudioIndex = _currentAudioIndex! - 1;
} else {
// if it's the first song, loop back to last song
currentAudioIndex = _audios.length - 1;
}
}
}
// listen to duration
void listenToDuration() {
// listen for total Duration
_audioPlayer.onDurationChanged.listen((newDuration) {
_totalDuration = newDuration;
notifyListeners();
});
// listen for current Duration
_audioPlayer.onAudioPositionChanged.listen((newPosition) {
_currentDuration = newPosition;
notifyListeners();
});
// listen for song completion
_audioPlayer.onPlayerCompletion.listen((event) {});
}
// dispose audio player
/*
G E T T E R S
*/
// List<Audio> get items {
// return [...audios];
// }
List<Audio> get audios => _audios;
int? get currentAudioIndex => _currentAudioIndex;
bool get isPlaying => _isPlaying;
Duration get currentDuration => _currentDuration;
Duration get totalDuration => _totalDuration;
List getAudioFilesById(int audioId) {
final audio = _audios.firstWhere((audio) => audio.audioId == audioId,
orElse: () => throw Exception('Audio ID not found'));
return audio.audioFile;
}
/*
S E T T E R S
*/
set currentAudioIndex(int? newIndex) {
//update current Audio Index
_currentAudioIndex = newIndex;
if (newIndex != null) {
playAudio(newIndex);
}
//update UI
notifyListeners();
}
Audio findById(int id) {
return audios.firstWhere((audio) => audio.audioId == id);
}
}
```
So now, I have to let it know the selected book and create a listTile of audioFiles related to that book. I also want the audioName to be reflected for each audioFile.
This is the audioList widget I created:
```
import 'package:audio_book_app/screens/audio_page_screen.dart';
import 'package:flutter/material.dart';
import 'package:audio_book_app/providers/audio.dart';
import 'package:provider/provider.dart';
class AudioList extends StatelessWidget {
const AudioList({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
final List<Audio> audios = Provider.of<List<Audio>>(context);
return ListView.builder(
itemCount: audios.length,
itemBuilder: (context, index) {
final audio = audios[index];
return ListTile(
leading: Image.network(
audio.bookImage,
width: 50,
height: 50,
),
title: Text(audio.audioName),
subtitle: Text(audio.audioName),
onTap: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => AudioPage(),
),
);
},
);
},
);
}
}
```
This is my audioplayerscreen.dart:
```

@override

}
class _AudioPlayerScreenState extends State<AudioPlayerScreen> {
late final dynamic audiosprovider;
late List audioFiles = [];
bool isPlaying = false;
// Duration duration = Duration.zero;
// Duration position = Duration.zero;
@override
void initState() {
super.initState();
audiosprovider = Provider.of<Audios>(context, listen: false);
final bookId = ModalRoute.of(context)!.settings.arguments as int;
audioFiles = audiosprovider.getAudioFilesById(bookId);
}
void goToAudio(int audioIndex) {
// update current audio index
audiosprovider.currentAudioIndex = audioIndex;
// navigate to song page
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => AudioPage(),
),
);
}
@override
Widget build(BuildContext context) {

},

}
}
```

How to create a listTile from a class in Flutter based on an collected id from the previous page |
|flutter|dart| |
null |
You'd have to edit file `gradle/libs.versions.toml` and add in TOML format:
[versions]
androidx_compose_bom = '2024.03.00'
androidx_compose_uitest = '1.6.4'
androidx_media3 = '1.3.0'
# ...
[libraries]
androidx_compose_bom = { module = "androidx.compose:compose-bom", version.ref = "androidx_compose_bom" }
androidx_compose_uitest = { module = "androidx.compose.ui:ui-test-junit4", version.ref = "androidx_compose_uitest" }
androidx_media3_exoplayer = { module = "androidx.media3:media3-exoplayer", version.ref = "androidx_media3" }
androidx_media3_exoplayer_dash = { module = "androidx.media3:media3-exoplayer-dash", version.ref = "androidx_media3" }
androidx_media3_exoplayer_ui = { module = "androidx.media3:media3-exoplayer-ui", version.ref = "androidx_media3" }
# ...
As one can see, one sometimes can use the version reference for multiple entries.
And one can even bundle these (optional):
[bundles]
exoplayer = ["androidx_media3_exoplayer", "androidx_media3_exoplayer_dash", "androidx_media3_exoplayer_ui"]
Which means, you can't just copy & paste, but have to convert to TOML.<br/>
Be aware that for BOM dependencies, this only works for the BOM itself.<br/>
When there's no version number, one can use: `//noinspection UseTomlInstead`.
The names of the definitions of the default empty activity app are kind of ambiguous, since they're not explicit enough. There `androidx` should better be called `androidx_compose`... because eg. `libs.androidx.ui` does not provide any understandable meaning (readability), compared to `libs.androidx.compose.ui`. Proper labeling is important there.

I am tryin to upload a new app to the App Store. It was built with expo and I am now tryin to build it using EAS.
I've uploaded my first and only app a few months ago.
From the root of my project I run:
`eas build --platform ios`
- Do you want to log in to your Apple account - I choose yes
- Apple ID (presented and correct) - I click yes
Then the following
Restoring session C:\Users\Yanay\.app-store\auth\yanaycodes@gmail.com\cookie
› Team My Name (My ID)
› Provider My Name (Some Numbers maybe another ID)
√ Logged in Local session
✔ Bundle identifier registered MY.ACTUAL.BUNDLE.IDENTIFIER
✔ Synced capabilities: Enabled: Push Notifications | Disabled: Sign In with Apple
✔ Synced capability identifiers: No updates
✔ Fetched Apple distribution certificates
- Reuse this distribution certificate?
Cert ID: SOME ID, Serial number: SOME SERIAL NUMBER, Team ID: MY TEAM ID, Team name: MY NAME (Individual) - I choose yes
- Generate a new Apple Provisioning Profile? - I choose yes
And then I get
✖ Failed to create Apple provisioning profile
Failed to set up credentials.
There is a problem with the request entity - You are not allowed to create 'iOS' profile with App ID 'APP ID'.
Error: build command failed.
What is happening?
I went to my developer account and I can even find that APP ID it shows me (last error log) in any of the apps (there like two there, one was just created to support apple log in).
How can I fix this?
This is my app.json if that helps

As of pydantic version 2.6.4, you cannot modify the behavior of `extra` on a per-call basis. However, you can easily remove the extra fields from the input to achieve equivalent behavior:
```python
validated = NoExtras.model_validate({key:value for key,value in somedict.items() if key in NoExtras.model_fields})
```
Be aware, this only works for flat models.

I figured this out. Those variables need to be marked as build variables within coolify's ui, and then under advanced there is an option that says force deploy without using cache. This forces next.js to rebuild again and put in the build environment variables. |
Based purely on [this documentation](http://re2c.org/manual/manual_c.html#regular-expressions), a form of lookahead is supported.
So one might hope that this would work:
```
BINARY_NUM = "0b" ("0"|"1") ("_"? ("0"|"1"))* / [^_01] ;
```
or slightly more compactly:
```
BINARY_NUM = "0b" [01]+ ( "_" [01]+ )* / [^_01] ;
```
although something more sophisticated would be needed, since the example above implies that:
```
0b010101010222
```
would be parsed as `0b010101010` followed by `222`.
However, I discovered "trailing contexts are not allowed in named definitions" when I tried substituting the above into the [introductory sample code in the manual](http://re2c.org/manual/manual_c.html#introduction).
Modifying it with [the "sentinel" example](http://re2c.org/manual/manual_c.html#sentinel), I get:
```
// re2c $INPUT -o $OUTPUT -i --case-ranges
#include <assert.h>
bool lex(const char *s) {
const char *YYCURSOR = s;
const char *YYMARKER;
for(;;) {
/*!re2c
re2c:yyfill:enable = 0;
re2c:define:YYCTYPE = char;
number = "0b" [01]+ ( "_" [01]+ )*;
number { continue; }
[\x00] { return true; }
* { return false; }
*/
}
}
int main() {
assert(lex("0b01_001"));
assert(lex("0b00000_"));
return 0;
}
```
This successfully rejects trailing `_`.
It is also possible to just include the null sentinel directly:
```
number = "Ob" [01]+ ("_"[01]+)* "\x00";
```
```
// re2c $INPUT -o $OUTPUT -i --case-ranges
#include <assert.h>
bool lex(const char *s) {
const char *YYCURSOR = s;
const char *YYMARKER;
/*!re2c
re2c:yyfill:enable = 0;
re2c:define:YYCTYPE = char;
number = "0b" [01]+ ( "_" [01]+ )* "\x00";
number { return true; }
* { return false; }
*/
}
}
int main() {
assert(lex("0b01_001"));
assert(lex("0b00000_"));
return 0;
}
```

Is there a way for Spark to read a single date partition from a Snowflake table, update it and then to overwrite this single date partition. Concurrent writes should be supported. Currently Spark has two overwrite modes, so I don't see a way to overwrite a single partition. It's an easy thing to do in Iceberg, as there overwrite mode overwrites only a single partition. Am I missing out some obvious solution?
I am interested in a solution that would not require transactions or complex SQLs. Ideally, the same behavior as in Iceberg, that is operation that allows to overwrite a single partition |

I’m interested in understanding the distinctions between context.watch and context.select in the context of blocs. Can you provide insights into when it is more appropriate to utilize watch and when select would be the better choice in a bloc scenario?
Thank you for your assistance in clarifying this matter. |
What is the difference between `context.watch` and `context.select` in flutter_bloc? |
|flutter|dart|bloc|flutter-bloc| |
In flutter_bloc, `context.watch` and `context.select` are both useful for interacting with the states of your blocs, but they have slightly different use cases.
`context.watch`:
Use `context.watch` when you want to listen to changes in the state of any bloc or Cubit and rebuild your widget whenever the state changes.
This can be useful when you need to rebuild your widget based on any change in the bloc state, regardless of which part of the state changed.
`context.watch` ensures that your widget rebuilds if any state in the observed bloc changes.
`context.select`:
Use `context.select` when you only want to listen to specific parts of the state and rebuild your widget when those specific parts change.
This can be more efficient than context.watch because it allows you to be more selective about which state changes trigger a rebuild.
By selecting only specific parts of the state to listen to, you can avoid unnecessary rebuilds when other parts of the state change.
In summary:
Use `context.watch` when you want to rebuild your widget on any state change in the observed bloc.
Use `context.select` when you want to be more selective about which state changes trigger a rebuild in your widget.
It’s generally better to use `context.watch` when you need to react to changes in various parts of the state, and context.select when you only care about specific parts of the state. Choose the one that best fits your specific use case to improve performance and minimize unnecessary widget rebuilds. |
Is there a way to get `cabal` to detect changes to non-Haskell source files? |
|haskell|cabal|template-haskell| |
Here's how you can do it:
In your HTML template, bind the (keydown.enter) event to a function that handles the "Enter key" press:
<!-- Assuming you have an input field -->
<input type="text" (keydown.enter)="onEnterPressed($event)">
In your component TypeScript file, define the onEnterPressed function to handle the "Enter key" press event. Within this function, prevent the default behavior of changing focus and instead call your API:
import { Component } from '@angular/core';
import { ApiService } from './api.service'; // Assuming you have an ApiService for making API calls
@Component({
selector: 'app-your-component',
templateUrl: './your-component.component.html',
styleUrls: ['./your-component.component.css']
})
export class YourComponent {
constructor(private apiService: ApiService) { }
onEnterPressed(event: KeyboardEvent): void {
event.preventDefault(); // Prevent the default behavior of changing focus
// Call your API here
this.apiService.callYourApi();
// Optionally, you can keep the focus on the current input field
// If you want to change focus, you can programmatically do so
// Example: event.target.blur(); // to remove focus from the current input
}
}
With this implementation, when the "Enter key" is pressed on any input field, it will trigger the onEnterPressed function, preventing the default focus change behavior, and instead calling your API. You can further customize this behavior as per your requirements. |
Is there a penalty to calling `with_column` many times in polars. Does it lead to dataframe "fragmenting"? |
Do repeated calls to polars with_column cause fragmenting? |

I override the main branch by:
`git push origin feature/create_ffmpeg_dockerfile`
`git push -f -u origin feature/create_ffmpeg_dockerfile`
my commite appear in the main branch
how can I restore the main?
I try this:
`git rebase --abort`
fatal: No rebase in progress
and also this:
`git revert <commit id>`
error: Reverting is not possible because you have unmerged files.
hint: Fix them up in the work tree, and then use 'git add/rm <file>'
hint: as appropriate to mark resolution and make a commit.
fatal: revert failed |
