Flutter-When i am changing value in respiratoryRate case and there i applied a setState after that i want to rebuild 'issue' case

var _respiratoryRate=0;

switch (cardioVascularWidget.key) {
case 'respiratoryRate':
VitalComponent? respiratoryRate = widget
.cardiovascularFormModel?.cardiovascularAssessment?.respiratoryRate;
return Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
CustomInputTextFormField(
titleText: respiratoryRate?.title ?? "",
hintText: respiratoryRate?.hintText ?? "",
trailingInputUnitText: respiratoryRate?.suffixValue ?? "",
isTitleRequired: true,
isTitleMandatory: true,
onEnteredValue: (value) {
setState(() {
_respiratoryRate = value;
});
},
),
],
);
case 'issue':
Issue? issue =
widget.cardiovascularFormModel?.cardiovascularAssessment?.issue;
return Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
TitleMandatoryWidget(isMandatory: false, title: '${issue?.title}'),
Text('$_respiratoryRate'),
],
);
}



In the switch case, you can see there I have a case 'respiratoryRate' in which have CustomInputTextFormField it return value inside onValueChange then i apply a

setState(() { _respiratoryRate = value ; });
and other switch case is 'issue' is there, i want to rebuild issues case

Access denied error using move-item to recursively move folders containing files with specific text

I'm scratching my head on this one and haven't found anything that gets it working.


I have a folder tree with a root1\yyyy\mm\dd\hh\uniqueid structure and need to move the uniqueid sub folders into a root2\yyyy\mm\dd\hh tree based on content within a specific json file in each uniqueid folder


After several searches I've arrived at the code below which is correctly identifying the folders I need to move, and creating the root2\yyyy\mm\dd\hh folders to hold the moved uniqueid folders, but it gives an access denied error trying to execute the move cmdlet
$root1 = My-Current-Root-Folder
$root2 = My-New-Root-Folder
(Get-ChildItem -Literalpath $root1 -Recurse -Filter *.json) | Select-String -Pattern content-I-am-looking-for | ForEach-Object {
$folderToMove = (Split-Path -Parent $_.Path)
$destinationFolder = $folderToMove.Substring(0, $folderToMove.Length - 33).Replace($root1 , $root2)
write-host $folderToMove #This correctly displays the source folders I need to move
write-host $destinationFolder #This correctly displays the root2 folder structure to hold the moved folders
If(!(Test-Path $destinationFolder)){
New-Item -Path $destinationFolder -ItemType "directory" #This correctly created the root2 folders for the move
}

move-item -path $folderToMove -destination $destinationFolder -Force
}



The error is like this:
move-item : Access to the path '$root1\2023\10\19\01\uniqueid' is denied.


But if I execute a move-item command explicitly specifying one of the uniqueid folders and the associated root2\yyyy\mm\dd\hh destination, the folder is moved without any issue.


All advice greatly appreciated


Tried wrapping the source and destination in double quotes in case that was needed and also specifying [string] on the source and destinations, but that just gives a different error (cannot find a drive F)

Triangular linear system with triangular right hand side in python

I have to solve a linear system of equations with multiple right hand sides, A*X=B, where both, A and B are (upper) triangular, real, square matrices. The size is about 200 by 200. Is there a fast method for this in python/numpy?


I was considering looping over the columns,
n=A.shape[0]
X=zeros((n,n))
for i in range(n):
X[:i+1,i]=solve_triangular(A[:i+1,:i+1],B[:i+1,i])



But this does not use fast matrix-matrix operations.


I could also do all right hand sides simultaneously, X=solve_triangular(A,B), but this does not take into account the triangular structure in B.


Finally, I could invert A and multiply with B, X=inv(A)@B, but inverting matrices is usually discouraged from.

Z-Function. String algorithms. Optimize for large strings

The problem:



Given a string s. For each i from 1 to |s|, find the number of occurrences of its prefix of length i in the string.


Input:

The first line of input contains an integer q (1≤q≤10^5) — the number of datasets in the test.


Each dataset consists of a string s. The length of the string s is from 1 to 10^6 characters. The string consists exclusively of lowercase Latin alphabet letters.


The sum of the lengths of strings s across all q datasets in the test does not exceed 10^6.


Output:

For each dataset, output |s| integers c1, c2, ..., c|s|, where c[i] is the number of occurrences of the prefix of length i in the string s.


Example


Input:
5
abacaba
eeeee
abcdef
ababababa
kekkekkek



Output:
4 2 2 1 1 1 1
5 4 3 2 1
1 1 1 1 1 1
5 4 4 3 3 2 2 1 1
6 3 3 2 2 2 1 1 1



The task must be solved exclusively using the Z-function, and the total time for a string of length 10^6 characters should not exceed 2 seconds.



My solution looks like this:
#include
#include
#include

std::vector ZFunc(const std::string& s) {
const int sz = s.size();
std::vector z(sz, 0);

for (int i = 1, l = 0, r = 0; i != sz; ++i) {
if (r >= i)
z[i] = std::min(z[i - l], r - i + 1);

while (z[i] + i < sz && s[i + z[i]] == s[z[i]])
z[i]++;

if (z[i] > r - i + 1) {
l = i;
r = i + z[i] - 1;
}
}

return z;
}

int main() {
int n;
std::cin >> n;

std::vector res(n);

for (int k = 0; k != n; ++k) {
std::string s;
std::cin >> s;

res[k].resize(s.size(), 1);
std::vector z = ZFunc(s);

for (int i = 1; i != z.size(); ++i) {
while (z[i]--)
res[k][z[i]]++;
}
}

for (const auto& ivec : res) {
for (int i : ivec)

I'm getting an unexpected Tensorflow ResourceExhaustedError when I try to use model.predict() with a Keras Sequential model

I'm using Python 3.9, and I have Tensorflow 2.10 installed with CUDA Toolkit 11.2 and cuDNN 8.2, as this was the last configuration to be supported natively on Windows 10.


I'm training using an NVIDIA GeForce RTX 2070 SUPER with 8Gb of VRAM, and I have 64 Gb of RAM on my PC.


I've used Keras to create a Sequential model to predict POS-tags. I've used the same model format to train models for text in several different languages. The models all trained alright, and when I run model.evaluate(test_data) they all produce a score. Similarly, when I run model.predict(test_data) most models produce the expected results, but there is one model, for one language, which acts differently.


This one model was trained the same as all the other models, so there should be no difference I think. When I run model.predict(test_data) using this model, at first it seems to be working. It starts applying the model to the dataset:
6/152 [=>............................] - ETA: 19s



It even appears to successfully complete this step, though it never gets as far as producing any results:
152/152 [==============================] - 20s 126ms/step



Unfortunately at this point it hangs and produces the following traceback:
2024-01-05 23:08:38.977923: W tensorflow/core/common_runtime/bfc_allocator.cc:479] Allocator (GPU_0_bfc) ran out of memory trying to allocate 2.61GiB (rounded to 2804106240)requested by op ConcatV2

I can't work out why it's only happening with this one model, or why there would be a problem with memory allocation when it works for all the other models. It doesn't seem like it's trying to use a lot of memory either. So why am I getting this error message? And, how can I fix it?


I've tried setting memory growth, but it didn't work:
physical_devices = tf.config.list_physical_devices('GPU')
tf.config.experimental.set_memory_growth(physical_devices[0], True)



I've also reduced batch sizes. This didn't help. I've even gone back and retrained the model in case there was something wrong with the model itself. Still have the same problem with the new model. As a last option, I tried splitting the test set into smaller divisions, running model.predict(test_data) on each of these divisions, then recombining the results of each division. It sometimes successfully predicts the first division, but always runs out of memory and gives me the same error by the second division.


Is there anything I can do?

Get parameters for currently running queries in PostgreSQL

We wrote a small tool which displays all currently running queries. We get the currently running queries from pg_stat_activity.



The problem is: We dont know the parameters which were given to the query. We can only see the placeholders $1, $2, etc.



Is there any way to get the parameters for a currently running query?



The only workaround could be to enable the query log and parse the parameters from the query log, but this would be a very dirty and slow solution.

Alpine adds a new build to work with Content Security Policies

---



Caleb Porzio announced that Alpine.js now has a CSP build that will with environments where CSP is required:



In order for Alpine to be able to execute plain strings from HTML attributes as JavaScript expressions, for example x-on:click="console.log()", it needs to rely on utilities that violate the "unsafe-eval" Content Security Policy that some applications may enforce for security purposes.


In order to accommodate environments where this CSP is necessary, Alpine offer's an alternate build that doesn't violate "unsafe-eval", but has a more restrictive syntax.



One thing to note with this new build is you must Alpine.data:



Since Alpine can no longer interpret strings as plain JavaScript, it has to parse and construct JavaScript functions from them manually.


Due to this limitation, you must use Alpine.data to register your x-data objects, and must reference properties and methods from it by key only.



This new build is available as a CDN or an npm install @alpinejs/csp


See the official documentation for complete details and for detailed instructions.


Note: When asked about Livewire support, Caleb says, "Not yet unfortunately because there is one or two places Livewire relies on eval (wire:click="something('one', 'two')") kinda thing"

R: Pattern matching one column to a json string stored in another column

I have a dataframe of untidy data: TX_JAN_2019_DF


This dataframe contains a columns TX_JAN_2019_DF$AREA (type: numeric) and TX_JAN_2019_DF$DEVICE_HOME_AREA (type: character)


TX_JAN_2019_DF$AREA[1] produces:[1] 481210216382


TX_JAN_2019_DF$DEVICE_HOME_AREA[1] produces a sample of the string (for this benefit of this post, this output is greatly reduced):


"{\"481210216382\":307,\"481210216371\":50,\"481210216381\":43,\"481130137213\":35,\"481210216373\":27,\"481130137222\":21,\"481210216154\":21,\"481210216152\":17,\"481210216133\":15,\"481210216372\":4}"


As you can see the json string is a string of values type character. I need to pattern match the first column TX_JAN_2019_DF$DEVICE[1], to see if the second column element TX_JAN_2019_DF$DEVICE_HOME_AREA[1] and the json string stored in that element contains the pattern and if it does, what is the number after the colon (307 for example in the first element).


Then of course do this for all columns TX_JAN_2019_DF$DEVICE_HOME_AREA


I'm at a loss on how to do this as the json adds a complication to normal pattern matching. I've looked at the jsonlite library, but the examples are not much help.


Thank you in advance

Use Model shouldBeStrict when starting a new Laravel app

---



So you have an idea for a brand new app. You install Laravel, you're ready to get started. What's the first thing you should do?


For me, I open up the app service provider and go down to the boot method and set the global Model::shouldBeStrict():
public function boot(): void
{
Model::shouldBeStrict();
}



With this turned on it does the following:
public static function shouldBeStrict(bool $shouldBeStrict = true)
{
static::preventLazyLoading($shouldBeStrict);
static::preventSilentlyDiscardingAttributes($shouldBeStrict);
static::preventAccessingMissingAttributes($shouldBeStrict);
}



This does three things:



* Prevents lazy loading

* It prevents silently discarding attributes.

* It prevents accessing missing attributes.






Preventing Lazy Loading




Here is an example of lazy loading.
$articles = \App\Models\Article::get();

foreach ($articles as $article) {
echo " * " . $article->user->name . "
\n";
}



If you run this, it will output what you expect. However, it’s lazy loading the user relationship, causing a new query for every loop.


With shouldBeStrict turned on instead of running the code you’ll get an error giving you instant feedback:
Attempted to lazy load [user] on model [App\Models\Article] but lazy loading is disabled.



Prevent Silently Discarding Attributes




Here is an example showing trying to update an attribute that is not fillable:
$user->fill(["remember_token" => "bar"]);



Now this will return an exception:
Add fillable property [remember_token] to allow mass assignment on [App\Models\User].



Prevent Accessing Missing Attributes.




Let’s pretend we are trying to display a property on the User that may not exist:
{{ $user->nonexistant }}



By default, Laravel will just not display anything because the property is not found, but with Strict mode turned on you get:
The attribute [nonexistant] either does not exist or was not retrieved for model [App\Models\User].



This really helps in cases where you might make a spelling mistake like:
{{ $user->emial }}



Now, you’ll get instant feedback you messed up.


Turning on Model::shouldBeStrict() is now the first thing I do on every app, and it helps prevent me from making basic mistakes that could be harmful to the app later on.

Generate PDFs in Laravel from Blade Views

---



The Laravel PDF package by Spatie provides a simple way to create PDFs in Laravel Apps. It uses Blade views to render HTML and create a PDF from that view using Browsershot. This opens up the ability to use modern CSS tools like Grid and Flexbox, modern CSS frameworks like Tailwind, and even JavaScript code for things like rendering charts.


Here's a basic example of creating a PDF and returning it from a controller, passing variables to the template that you can use to dynamically render the PDF data:
use Spatie\LaravelPdf\Facades\Pdf;

class DownloadInvoiceController
{
public function __invoke(Invoice $invoice)
{
return Pdf::view('pdfs.invoice', ['invoice' => $invoice])
->format('a4')
->name('your-invoice.pdf');
}
}



At launch, the Laravel PDF package supports the following features:



* Render PDFs from Blade templates or an HTML string

* Save a generated PDF to a Laravel disk

* Run JavaScript code when the PDF is created

* PDF testing fake with powerful assertions

* Generate PDFs on Lambda via Laravel Sidecar

* Advanced PDF control with tools like page breaks, Browsershot customization

* And more...






Creating PDFs in Laravel with Blade will make generating beautiful custom PDFs easier and more powerful than ever! To get started, check out the official Laravel PDF documentation. The source code is available on GitHub at spatie/laravel-pdf.

DataSnap - how to change SELECT query to show different data?

In DataSnap, I have a server and client. In the client, I use this code to show data in a TDBGrid:
ClientDataSet1.CommandText := 'SELECT * from table_name WHERE autoid = 10';
ClientDataSet1.Open;
ClientDataSet1.Refresh;



But when I want to change this, the TDBGrid is not showing different data, it still shows data from my first code:
ClientDataSet1.CommandText := 'SELECT * FROM table_name WHERE autoid = 1';
ClientDataSet1.Open;

Is there any way to observe all data attributes in a custom component?

I'm trying to use vanilla javascript to build a custom component which observes changes in all data attributes, e.g.:
class MyComponent extends HTMLElement {

static get observedAttributes () {
return ["data-one","data-two","data-three",so forth...]
}

}



This component could in theory be assigned an arbitrary number of data attributes, so there's no way to predict exactly how many there would be, yet I need the component to do stuff every time a new data attribute is assigned to it, is there any way to do it? having to put into the array returned by "observedAttributes" the specific name of every attribute seems really restrictive


As a bonus, is there any way to observe attributes that don't have a specific name but follow a certain pattern? (e.g. they match against a regex string or something like that)


And as an extra bonus, is there any way to observe all attributes? (I know they made this not be the default behavior due to performance factors, but still it would be good to be able to enable it if needed)

Laravel SQS DLQ

Hey laravel folks,

​

We are currently in the process of migrating to AWS and we are thinking about using SQS for the queue driver. We created DLQ for the queues we created but it seems it's not needed since laravel internally stores the failed jobs in the `failed_jobs` table in database? Is my assumption correct and should we just not create DLQ on sqs for the queues?

How to fill out existing PDF?

Hey all. Looking for some help.

I’m building an application that needs to dynamically generate 1099 tax forms for contractors. I’d love to be able to just lay text on top of the existing PDF form from the IRS, even if it’s just by using x and y coordinates to target the specific fields, since the file is not directly editable.

Is there an easy way of doing this? I’m very familiar with the Laravel-dompdf package (
https://github.com/barryvdh/laravel-dompdf), but I don’t believe this is possible.

Should I just build my own version of the IRS form and generate the entire thing from scratch? I’m just not sure if that’s frowned upon by the IRS and/or compliant.

Any direction would be appreciated. Thanks! submitted by /u/brycematheson

Any good AI tools that stay up-to-date with the latest versions of Laravel or Livewire or related resources

I've been trying to solve a particular problem for a while now with filament. Sometimes AI tools help get me where i need to be, but when they are outdated in their reference material, it can create more confusion if there is considerable code change

I've tried a few including the one on laracast, chat gpt, and codieum but they seem to be only updated to livewire v2-- and therefore filament v2 submitted by /u/jcc5018

i want to create a new order with 2 products and corresponding amount specified. here is how i implement it:
public class OrderEnpoint
{
public static void Map(WebApplication app)
{
app.MapPost("/order", async (DkdbContext db, OrderDto orderRequest, UserManager userManager) =>
{
if (orderRequest == null || string.IsNullOrEmpty(orderRequest.UserId))
return Results.BadRequest();

var user = await userManager.FindByIdAsync(orderRequest.UserId);

var newOrder = new Order
{
UserId = orderRequest.UserId,
CreatedBy = user?.UserName,
UpdatedBy = user?.UserName,
};

await db.Orders.AddAsync(newOrder);
await db.SaveChangesAsync();

var _OrderDetails = orderRequest.ProductOrderList
.Select(e => new OrderDetail
{
OrderId = newOrder.Id,
ProductId = e.ProductId,
Amount = e.Amount,
}).ToList();

await db.OrderDetails.AddRangeAsync(_OrderDetails);
await db.SaveChangesAsync();

return Results.Created();
});
}
}



here is my data transfer object class:
public class OrderDto
{
public string UserId { get; set; } = string.Empty;
public List ProductOrderList { get; set; } = [];
}

public class OrderRequest
{
[Required]
public int ProductId { get; set; }
[Required]
public int Amount { get; set; }
}



When i debug this code, I am able to see order record created in Orders table, but not in OrderDetails. am using postgres as database. here is what the error look like:
---> Npgsql.PostgresException (0x80004005): 23502: null value in column "UserId" of relation "Orders" violates not-null constraint

i expect to be able to create a new Order with associated OrderDetail with amount respectively. I am looking for solutions, am glad if someone can help. thank you.

Compression of randomly ordered non-repeating incremental integers

I have a set of 100 integers from 0-99 in random order. Each number in the range occurs exactly once. I am looking for the most effective lossless compression algorithm to compress this data while maintaining the ability to decompress it efficiently?


I know that compressing random numbers is theoretically not possible, but I'm wondering if it's possible for this case since each number only appears once and you basically just need to compress the order of the numbers somehow... Please don't be harsh, I'm not an expert in this field. Also, any tips for python implementations would be greatly appreciated! :)


Thanks in advance.

Does a timer-triggered Azure function execute if an instance of the function is already executing?

I have an Azure Function App with the [TimerTrigger(...)] attribute, which is scheduled to execute every morning.


Suppose you manually execute the function via the Function Menu Blade -> Code + Test -> Test/Run, as shown at the bottom of this message. What happens if this manual execution of the function is still running when the time specified in the TimerTrigger attribute arrives?



* Will the manual execution be interrupted by the timer-triggered execution?

* Will the manual execution prevent the timer from triggering a new execution of the function?

* Or will a new instance of the function be kicked off when the timer triggers it, running in parallel with the existing manual execution?
