I am writing a program that embeds Deno however Deno has a lot of dependencies that are using static versions which conflict with the dependencies I have in my main project.
To get around this I'm wondering if it's possible to compartmentalize my Deno integration into a seperate crate in my workspace that builds a dynamic rust library that statically contains all of its own dependencies.
I'd then consume the dynamic library dynamically from my main application.
I know that Rust doesn't have a stable ABI but an rlib compiled on the same version of Rust as the a consumer is compatible - but given the library will live within the same workspace and built as a prerequisite to the main binary - I assume that's fine.
Is this possible and would this resolve my issues?
Is `crate-type` `rlib` the correct way to do this or would it be `lib`?
|
Can I compartmentalize dependencies of a crate within a local dynamic rlib? |

From what it looks like this your trying to put this at the bottom of your page, if that's the case it might be easiest to put in your CSS the attribute position and assign it to absolute and then in the attribute bottom to 0px
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-css -->
.wave { position: absolute;
bottom: 0px;
}
.background { position: absolute;
bottom: 0px;
}
<!-- language: lang-html -->
<body>
<div class="background" style="background-color:blue; width: 100%; height:40px" >
</div>
<div class="wave" style="background-color:orange; width: 100%; height:10px" >
</div>
</body>
<!-- end snippet -->
hope this helps! |
I have a dataframe which includes the following variables: `covid alert date`, `vax dose 1` to `vax dose 5` (these are vaccine brands), `date dose 1` to `date dose 5` (these are the vaccination dates).
The dataset includes all covid vaccines they have ever received however I really only want to keep the vaccine brands and dates that fall before their `covid alert date`. Is there a way to look at the `covid alert date` for each row and only keep the vaccine brands and dates that fall before that date? Anything after that date can be changed to NA.
```
sample_data <- tibble(`covid alert date` = as.Date(c('2022-01-01','2022-02-01','2022-03-01','2022-04-01','2022-05-01','2022-06-01','2022-07-01','2022-08-01','2022-09-01','2022-10-01')),
`vax dose 1` = c("Astrazeneca", "Moderna", "Pfizer", "Astrazeneca", "Moderna", "Pfizer", "Astrazeneca", "Moderna", "Pfizer", "Astrazeneca"),
`date dose 1` = as.Date(c('2021-01-01','2021-02-01','2021-03-01','2023-04-01','2023-05-01','2021-06-01','2021-07-01','2021-08-01','2023-09-01','2023-10-01')),

`vax dose 3` = c("Pfizer", "Moderna", "Pfizer", "Moderna", NA, NA, NA, NA, NA, NA),

This question is a continuation of my previous one about https://stackoverflow.com/questions/78218233/re-binding-the-selectinput-of-a-datatable-after-being-updated.
So, I made quite some progress on this app and I have reached a result that perfectly fits my needs. The app correctly updates the target database and the selectInputs as well as the filter are intuitive and user-friendly enought for what I seek.
There is however one issue, not a critical one but still rather annoying. When the "Update Data" button is clicked on and the underlying data is updated, the displayed datatable acts as if there where no category selected in the filter and returns an empty table. This issue is fixed the moment a modification is made on the filtered categories through the filter button and it doesn't stop the database to be correctly updated, but this is not an expected behaviour.
What is weird is that it seems to be caused by the the virtualSelectInput filter and not the fact that the underlying is filtered, because when I filter it directly in the code, it works just fine. Well aside from the fact that when doing the latter options, if the "Update Data" button is clicked on while no SelectInput has been changed, it will not trigger any update after that even if a SelectInput was later on changed to another value, whereas it works as intended as long as a SelectInput has been changed vefore each time the "Update Data" button has been triggered.
I suspect those two issues to be related one way or another. Is there something that I missed or mishandled ?
Below are the records of the issues :
[![First Issue][1]][1]
* Issue where the DataTable is empty after an update, but display the change after resetting the filters
[![Normal Behaviour][2]][2]
* Without the virtualSelectInput acting as a filter (expected behaviour)
[![Issue 2][3]][3]
* Without the virtualSelectInput acting as a filter, but without changing a SelectInput before updating a first time (cannot update a change after that)
**Here are the commands to create the dummy database used for the app :**
```
### Initialize the two MySQL Databases used in the code
# The Databases are not important in themselves but are handy to test and tinker what I need
CREATE TABLE Z_TEST (ID INT PRIMARY KEY NOT NULL, Divinite VARCHAR(20), ID_pantheon INT);
CREATE TABLE Z_TEST2 (id_pantheon INT PRIMARY KEY NOT NULL, nom_pantheon VARCHAR(20)), id_parent INT;
INSERT INTO Z_TEST VALUES

(2, "Odin", 1),
(3, "Ra", 3),
(4, "Zeus", 1),
(5, "Tiamat", 4),
(6, "Isis", 0),
(7, "Hades", 0),
(8, "Thot", 0),
(9, "Thor", 0),
(10, "Persephone", 0),
(11, "Amatsu", 0);

(9, "Mineure", 2),
(10, "Majeure", 2),
(11, "Mineure", 3),
(12, "Majeure", 3);
### Display each Database and their join
SELECT * FROM Z_TEST;

I am trying to call a function included in the C standard library (namely, `puts`, but it shouldn't matter) from an assembly program. Creating an object file from the assembly code works but the linking stage does not. As I am a complete beginner on assembly programming I am basically unable to even interpret the error messages. Any help or explanation on what is going wrong would be really appreciated!
I loosely followed this [tutorial](https://cs.lmu.edu/~ray/notes/nasmtutorial/), but having code identical to it still doesn't work. My expectation is that I would get an executable file, but in reality I don't get past the linking stage.
My code: (`file.asm`)
```
global main
extern puts
section .text
main:
mov rdi, msg
call puts
ret
msg:
db "Hello, world!", 0
```
Commands and errors:
```
$ nasm -felf64 file.asm
$ gcc file.o
/usr/bin/ld: warning: file.o: missing .note.GNU-stack section implies executable stack
/usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
/usr/bin/ld: file.o: warning: relocation in read-only section `.text'
/usr/bin/ld: file.o: relocation R_X86_64_PC32 against symbol `puts@@GLIBC_2.2.5' can not be used when making a PIE object; recompile with -fPIE
/usr/bin/ld: final link failed: bad value

$
```
I have tried searching for help on this on the internet but I see no difference from what I am already doing. |

I am using azure-devops-migration-tools to migrate from TFS 2017 to Azure Devops SERVER 2022. I have some questions.
1) Validation - Not all Test plans are migrated. Trying to come up with a way of quickly verifying all the Test Plans and Test Suite have been migrated. A Query in the source shows more test plans / suites than in the destination. However, the number of test plans / suites visible in the "Tests" app of TFS does appear to match. Can't really tell with Test suites because there are so many. Since there is limited to no filtering capabilities I am wondering which Test Plans / Suites get skipped and if there is a way to identify them in the source before the migration.
2) We ran into an issue in one migration where test suites were not completely migrated because of being associated with test cases which had INACTIVE test configurations. We made all the test configurations ACTIVE on the source in hopes of getting a complete migration, but the test configurations were not updated and remained INACTIVE on the target. Do Test Plans, Suites, Configurations get updated like work items do?
Just trying to come up with a best practice for Test "objects" so I can validate what was migrated.
Also an understanding of what will definitely not be migrated because it is not possible. This is so I can set Product Team expectations and be able to quantitatively analyze the results and be confident I migrated all that is possible to migrate. |

my task is to create drag and drop interface, where user drags an element, which changes its appearance during that short amount of time - till it is dropped in its destination.
I would like to do it with native Web API. I have found the event called "dragstart" in [MDN Documentation][1]. And prepared this [fiddle][2] to demonstrate the behaviour.
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
const source = document.getElementById("draggable");
source.addEventListener("dragstart", (event) => {
event.target.classList.add("dragging");
});
source.addEventListener("dragend", (event) => {
event.target.classList.remove("dragging");
});
<!-- language: lang-css -->
body {
/* Prevent the user from selecting text in the example */
user-select: none;
}
#container {
width: 400px;
height: 20px;
background: blueviolet;
padding: 10px;
}
#draggable {
text-align: center;
background: white;
}
.dragging {
width: 422px;
color: red;
font-weight: 700;
}
<!-- language: lang-html -->
<div id="container">
<div id="draggable" draggable="true">Drag me</div>
</div>
<div class="dropzone"></div>
<!-- end snippet -->
However the result is not sufficient. In my task I need the default element to persist its appearance and change only the dragged minimised version of it - ideally it should be narrower and show a little different content than the default element.
If you knew any source, where this task is resolved (anyhow), I'd be glad for your reply.

I'm currently confused about windows and states. Suppose I have a program that counts user access data every minute and needs to do sum statistics in each window. Assume that at this time, I configure checkpoint for the fault tolerance of the program. The checkpoint configuration is to trigger every 30 seconds. Then when the time is 01:00, the program hangs. In theory, it can only be restored to the state data at 00:30, but there is no trigger window at 00:30. After calculation, we get the kafka offset data at 00:30 and the window data at 00:00. Is there any problem with my understanding?
here is my program,flink version is 1.14:
[flink graph][1]

}
}
The resulting phenomenon is:
Suppose I cancel the task at 00:31:30, then when I restart the task, the statistics at 00:31:00 will be less than expected. I found out by printing records that it was because when the sink wrote the data at 00:30:00, the kafka consumer had actually consumed the data after 00:31:00, but this part of the data was not written to ck. , it was not replayed in the window when restarting, so this part of the data was lost. The statistics will not return to normal until 00:32:00.

I want to be able to measure any code snippet time complexity. Is there a general rule or step by step approach to measure any big o (besides dominant term, removing constants and factors)? What math skills should I have, if so, what are the prerequisites for those skills?
Here is one of those:
```
int fun(int n) {
int count = 0;
for (i = n; i > 0; i /= 2) {
for (j = 0; j < i; j++) {
count += 1;
}
}
return count;
}
```
I've read many algorithms books, but they're mathy and not beginner-friendly. |

The `cy.stub()` command uses Sinon under the hood, so the first thing you need is the [sinon types](https://www.npmjs.com/package/@types/sinon):
```js
npm install --save @types/sinon
```
and add in **tsconfig.json**
```js
{
"compilerOptions": {
...
"types": ["cypress", "@testing-library/cypress", "node", "@types/sinon/index.d.ts"]
```
Then in the test you can solve #1 wrappedMethod with a cast, and #2 `.as()` by reversing the chaining order
```js
cy.window().then((win) => {
cy.stub(win, 'open')
.as('open')
.callsFake((url, target) => {
expect(target).to.be.undefined;
return (win.open as sinon.SinonStub).wrappedMethod.call(win, url, '_self')
})
})
```

I am using an old shader used for a character model from the Unity asset store that has depreciated. The asset has been made free and some people have put out some updated versions but no one has put out a shader that works in VR without enabling the multipass.
I have looked at Unity's guide for amending shaders for VR:
[text](https://docs.unity3d.com/2023.1/Documentation/Manual/SinglePassInstancing.html)
I have tied to follow this guide with my little to none experience with Shaders but I cannot get it to work.
Can anyone help me to update the shader so it works?

`idx.get_level_values` seems to be the fastest.
However, since MultiIndexes are iterables, an easy way would be to use [`zip`](https://docs.python.org/3/library/functions.html#zip):
```
out = list(zip(*idx))
```
Output: `[('A', 'A', 'B', 'B'), ('C', 'D', 'C', 'D')]`
As lists:
```
out = list(map(list, zip(*idx)))
# [['A', 'A', 'B', 'B'], ['C', 'D', 'C', 'D']]
```
#### timings
Tested on 20 levels, ~1M rows:
```
# list(zip(*idx))
733 ms ± 17.6 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
# [idx.get_level_values(i) for i in range(len(idx[0]))]

I'm working on a blog in Astro, and I'm trying to render the markdown from the blog post to HTML in using @astropub/md?
**Sample markdown blog post**
```md

<a href={`/blog/${post.slug}/`}>{post.data.title}</a>
<Markdown of={post.body} />
</li>
))
}
</ul>
```
**The issue**
The image is only loading on the single blog post, not in the blog overview.
It's almost as if Vite isn't parsing images loaded through @astropub/md's <Markdown /> component.

VSCode happily supports this starting in January 2024 (version 1.86). See
https://code.visualstudio.com/updates/v1_86#_review-multiple-files-in-diff-editor.
Note the `...` menu with the "Inline View" toggle item seems to be missing though for "multi diff". So to get inline view you need to add ` "diffEditor.renderSideBySide": false` to your settings.

The reason for the error was I put the following code inside the for loop.
After moving the code outside the loop, the only thing I changed was the code from:
```
$d = DateTime::createFromFormat("Y-m",$current_date);
```
to:
```
$d = DateTime::createFromFormat("Y-m-d",$current_date);

You create a `Proxy` with two parameters:
* **target**: the original object which you want to proxy
* **handler**: an object that defines which operations will be intercepted and how to redefine intercepted operations. The objects entries are called "traps". This is analogous to the concept of _traps_ in operating systems. It can contain the following traps:
* `getPrototypeOf()`
* `setPrototypeOf()`
* `isExtensible()`
* `preventExtensions()`
* `getOwnPropertyDescriptor()`
* `defineProperty()`
* `has()`
* `get()`
* `set()`
* `deleteProperty()`
* `ownKeys()`

So i have managed to store my image on firebase storage from my node js backend and storing the link to that image in my database also but when I try to go to the URL where my image is stored I get the error in the image attached so looked it up and tried changing my rules for my storage to allow read from all but still get that error does anyone know why as I want to display this image on the client side of my app but it doesn't work right now as access isn't allowed do you need to give the token to access it or is there anyway that the rules can be modified that any user can view (so read) but only authed can write?

You can do this, and I have managed to do it successfully. But it takes some effort. Here are some things I would suggest keeping in mind.
1) Figure out the Image format that you are extracting from. If you do a binwalk on `bzImage`, you'll see compressed images at various locations.
2) manually extract the kernel `vmlinux` from the `bzImage`. You'll need to figure out exactly what compression was used so you can recompress it later
3) while you can use `vmlinux-to-elf` to create an ELF file that contains symbols, you should only use that as a reference for debugging/analysis with Binary Ninja, Ghidra, IDA etc... Don't try to modify the resulting elf file and packing it back up.
4) modify the extracted vmlinux in the tool of your choice, patch asm etc...
5) when you're done, save the binary, compress it again with exactly the same options as the original, and replace the data in the original `bzImage` file.
For step `2`, I would recommend looking at the kernel sources to determine specific flags for compression, and make sure that you can uncompress and recompress without making any changes to the file. The recompressed file should be identical to the original compressed version.
Probably not the answer you were looking for, but hopefully helpful to someone in the future. I may at some point do a writeup with examples since it's pretty fun and interesting. |
You can delete a endpoint using the python azure ml sdk
from azureml.core import Workspace, Webservice
service = Webservice(workspace=ws, name='your-service-name')
service.delete()
Then if you want to re create you can re deploy the model
from azureml.core.model import InferenceConfig
from azureml.core.webservice import AciWebservice
from azureml.core.model import Model
service_name = 'my-custom-env-service'
inference_config = InferenceConfig(entry_script='score.py', environment=environment)
aci_config = AciWebservice.deploy_configuration(cpu_cores=1, memory_gb=1)
service = Model.deploy(workspace=ws,
name=service_name,
models=[model],
inference_config=inference_config,
deployment_config=aci_config,
overwrite=True)

I am porting some code that defined tty_ldisc_ops.ioctl() as:
````
static int ...ldisc_ioctl(struct tty_struct *tty, struct file *file, unsigned int cmd, unsigned long arg)
````
But the current spec (https://docs.kernel.org/driver-api/tty/tty_ldisc.html#id3) is:
````
static int ...ldisc_ioctl(struct tty_struct *tty, unsigned int cmd, unsigned long arg)
````
What happened to the "file" argument? I looked for change logs and source. |
Was there a previous version of tty_ldisc_ops.ioctl() that also required a file argument? |

I am working on a web api that consumes Spotify API and I can't make the call for the search endpoint. It's my first time making an API consumes other and also my first time using stack overflow, so I really dont know how to explain to you guys but I will pass part of the code that I think its important
```
@RestController
@RequestMapping("/spotify/api")
public class SearchController {
private final AuthSpotifyClient authSpotifyClient;
private final SearchClient searchClient;
public SearchController(AuthSpotifyClient authSpotifyClient, SearchClient searchClient) {
this.authSpotifyClient = authSpotifyClient;
this.searchClient = searchClient;
}
@GetMapping("/search")
public ResponseEntity<SearchResponse> search(@RequestBody String q, @RequestBody String type){
var request = new LoginRequest(
"confidential",
"confidential",
"confidential"
);
var token = authSpotifyClient.login(request).getAcessToken();
var response = searchClient.search("Bearer " + token,
q, type);
return ResponseEntity.ok(response);
}
}
@FeignClient(
name = "SearchClient",
url = "https://api.spotify.com/v1/search?"
)
public interface SearchClient {
@GetMapping("?q={q}&type={type}")
SearchResponse search(@RequestHeader("Authorization") String authorization,
@PathVariable String q, @PathVariable String type);
}
```
When I run it the endpoint returns 400 Bad Request |

Supabase auth sessions are stored client-side, so in theory clearing local storage without calling your logout API endpoint should suffice. However the downside is that if the user is logged in on multiple devices, this will only log them out on the current one.
Ideally yes, you would have the Supabase client on your frontend. Any alternative would be a bit hacky, such as interacting with the users table directly rather than auth sessions. |
I concur with the point mentioned by @eliasah. You can implement checkpointing to improve the performance of the long lineage that is created.
Additionally I would suggest you containerize the `List[(DataFrame, Seq[String], String)]` into a case class so that there is readability, type safety as the compiler will catch any attempt to use the value of wrong type.
```scala
case class JoinInfo(df: DataFrame, joinCols: Seq[String], joinType: String)
/**
* Join the dataframes based on the joinInfos provided and return the resulting dataframe
* @param baseDf The base dataframe to join with
* @param joinInfos The list of dataframes to join with the base dataframe
* @param shouldCheckpoint Whether to checkpoint the resulting dataframe
* @return The resulting dataframe after joining all the dataframes
*/
def joinDataframes(baseDf: DataFrame, joinInfos: List[JoinInfo], shouldCheckpoint: Boolean = false): DataFrame = {
joinInfos.foldLeft(baseDf) {
case (currentDf, JoinInfo(df, joinCols, joinType)) =>
val joinedDf = currentDf.join(df, joinCols, joinType)
if (shouldCheckpoint && spark.sparkContext.getCheckpointDir.isDefined) {
joinedDf.checkpoint()
} else {
joinedDf
}
}
}
```
This is comparatively scalable as well, since if you want to add an extra parameter you can do so by modifying the case class instead of adjusting the elements.
You can now use it on the data as below:
```scala
val tableA = // data
val tableB = // data
val tableC = // data
val joinInfos = List(
JoinInfo(tableB, Seq("id", "name"), "inner"),
JoinInfo(tableC, Seq("id"), "inner")
)
val joinedDf = joinDataframes(tableA, joinInfos, shouldCheckpoint = true)
```
Here, you are performing the checkpoint when it is enabled in your session. When `checkpoint` is performed on an RDD or DataFrame, Spark saves the data to a checkpoint directory on disk and uses this saved version for future actions. This means that the next time an action is performed on the RDD or DataFrame, Spark doesn't need to compute the entire lineage, but only the transformations that were applied after the checkpoint. |

Firstly, I'm so sorry if this is a dupplicated question.
let's say I have a simple python code named decorator.py with decorator here:
```python
`def decorator(func):
def wrapper():
print("Before function.")
val = func()
print("After function.")
return val
return wrapper() # <- please pay attention to this line`
@decorator
def hello():
print("hello!")
@decorator
def good_bye():
print("good_bye!")
@decorator
def thank_you():
print("thank_you!")
@decorator
def thanks_a_lot():
print("thanks_a_lot!")
```
the result after running the code
```
Before function.
hello!
After function.
Before function.
good_bye!
After function.
Before function.
thank_you!
After function.
Before function.
thanks_a_lot!
After function.
[Finished in 46ms]
```
this mean, return wrapper() calls all my functions?
what is the difference between wrapper() and wrapper in this case.
I appreciate for your explaination.
I'm tring to run on debug mode to find out, but still got nothing, I hope I'll get a detail explaination |

I am learning about design patterns in Python and wanted to combine the abstract factory with the delegation pattern (to gain deeper insights into how the pattern works). However, I am getting a weird recursion error when combining the two patterns, which I do not understand.
The error is:
[Previous line repeated 987 more times]
File "c:\Users\jenny\Documents\design_pattern\creational\abstract_factory.py", line 60, in __getattribute__
def __getattribute__(self, name: str):
RecursionError: maximum recursion depth exceeded
The code is:
from abc import abstractmethod
class ITechnique:
#abstract product
def display(self):
pass
def turn_on(self):
print("I am on!")
def turn_off(self):
print("I am off!")
class Laptop(ITechnique):
#concrete product
def display(self):
print("I'am a Laptop")
class Smartphone(ITechnique):
#concrete product
def display(self):
print("I'am a Smartphone")
class Tablet(ITechnique):
#concrete product
def display(self):
print("I'm a tablet!")
class IFactory:
@abstractmethod
def get_hardware():
pass
class SmartphoneFactory(IFactory):
def get_hardware(self):
return Smartphone()
class LaptopFactory(IFactory):
def get_hardware(self):
return Laptop()
class TabletFactory(IFactory):
def get_hardware(self):
return Tablet()
class Client():
def __init__(self, factory: IFactory) -> None:
self._hardware = factory.get_hardware()
def __getattribute__(self, name: str):
return getattr(self._hardware, name)
if __name__ == "__main__":
client_with_laptop = Client(LaptopFactory())
client_with_laptop.display()
client_with_tablet = Client(TabletFactory())
client_with_tablet.display()
client_with_smartphone = Client(SmartphoneFactory())
client_with_smartphone.display()
When I access the attribute _hardware and remove the get_attribute section (so, basically, when I remove the delegation pattern), everything works as expected. See below the modified code section, which works:
class Client():
def __init__(self, factory: IFactory) -> None:
self._hardware = factory.get_hardware()
if __name__ == "__main__":
client_with_laptop = Client(LaptopFactory())
client_with_laptop._hardware.display()
client_with_tablet = Client(TabletFactory())
client_with_tablet._hardware.display()
client_with_smartphone = Client(SmartphoneFactory())
client_with_smartphone._hardware.display()
Can anybody help me explain why the recursion error occurs or how to fix it. My objective was (1) to have varying devices depending on the factory used in client and (2) to be able to call the methods from the `_hardware` without typing `client._hardware` all the time but calling it directly from the client object, e.g. `client.display()`. It is not whether this is, in reality, a useful approach or not; I simply want to understand the pattern - and the occurring error - better. :-)

Here is the complete content of my .pro file (I have specified to add the network module):
```
QT += quick virtualkeyboard network
# You can make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0
CONFIG += c++14

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target
```
However, when I use the QNetwork module in my QML file like this:
```
import QtNetwork 2.15
```
I am pointed out with the issue:
```
QML module not found (QNetwork)
Import paths:E:/Qt/5.15.2/msvc2019/qml
For qmake projects, use the QML_IMPORT_PATH variable to add import paths.
For Qbs projects, declare and set a qmllmportPaths property in your product to add import paths.
For qmlproject projects, use the importPaths property to add import paths.
For CMake projects, make sure QML_IMPORT_PATH variable is in CMakeCache.txt.
For qmlRegister.. calls, make sure that you define the Module URl as a string literal.
```
I checked folder '**E:\Qt\5.15.2\msvc2019**', and indeed, I did not find any files related to the QNetwork module. What is going on? How should I use this module?
I have tried various solutions found online, but many of them are aimed at Visual Studio IDE. In reality, I am using **Windows 10 22H2 with QT 5.15, MSVC2019 32bit** compiler, and my Integrated Development Environment (IDE) is **QT Creator**. |

Its because of the `*` which is a quantifier that allows for zero occurrences, meaning it can also match empty strings, change it to `+` which is quantifier for one or more occurrences of the preceding element

It appears you are handling the provider context wrong, instead of storing the context in a variable and using it later, consider using a callback or a notifier to trigger changes in your provider, something like this:
import 'package:flutter/material.dart';
import 'package:provider/provider.dart';
import './providers/socket_data_provider.dart';
import 'package:wineasy/screens/test.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return MultiProvider(
providers: [
ChangeNotifierProvider(create: (context) => SocketDataProvider()),
],
child: MaterialApp(
debugShowCheckedModeBanner: false,
theme: ThemeData(
colorScheme: ColorScheme.fromSeed(seedColor: Colors.red),
useMaterial3: true,
),
home: const Scaffold(
body: Test(),
),
),
);
}
}
and in you socketDataProvider:
class SocketDataProvider extends ChangeNotifier {
// Your socket data
void initializeSocket() {
// Setup your socket connection here
// On receiving data, call setSocketData
}
void setSocketData(dynamic orders) {
// Update your data
notifyListeners();
}
}
and to get the SocketData simply use:
final socketData = Provider.of<SocketDataProvider>(context); |

7:{'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ':''}
}
function changeFont(text) {
let output = '';
for (const font in fonts) {
const alphabet = Object.keys(fonts[font])[0];
const transformedText = text.split('\n').map(line =>
line.split('').map(char =>
(alphabet.includes(char) ? fonts[font][alphabet][alphabet.indexOf(char)] : char)
).join('')
).join('\n');
output += transformedText + '\n\n';
}
return output;
}
let newText = 'Feliz, Navidad.'
let orignalText = 'Feliz, Navidad.'
function changeInputText() {
newText = changeFont(orignalText)
console.log(newText)
}
</script>
```
The output it gives is this:

As you can see, The first to lines are correct but other are weird and look corrupted.
Its self explanatory, i expected the converter to convert the text into different fonts correctly but instead only 2 fonts were correct and others were looking weird and corrupted. |

The generated formatting command is converting the full path (other than the remote server) to uppercase. Correcting the casing on the uppercase path fixes the command (note that the lowercase path is also incorrect, but it doesn't seem to matter). How can I configure the clang-format command line to prevent modifying the path casing? |
**UPDATE: 2023**
You will need `s3fs` to be installed as that's what pandas uses now.
This will most probably be a permission issue with either your IAM configuration or the way you're calling `boto3` not configured properly. Also depends if it's running locally, on an ec2 etc.
**OLD ANSWER**
Pandas uses `boto` (not `boto3`) inside `read_csv`. You might be able to install boto and have it work correctly.
There's [some troubles](https://github.com/pydata/pandas/issues/11915) with boto and python 3.4.4 / python3.5.1. If you're on those platforms, and until those are fixed, you can use boto 3 as
import boto3
import pandas as pd
s3 = boto3.client('s3')
obj = s3.get_object(Bucket='bucket', Key='key')
df = pd.read_csv(obj['Body'])
That `obj` had a `.read` method (which returns a stream of bytes), which is enough for pandas. |
