Material UI is intended for Android only and isn't cross-platform. There is an alternative, but it's not official. I found this: https://github.com/MDC-MAUI/MDC-MAUI
Don't feel bad. I've been developing strategies for the OKX platform for a while now, and when I tried my first Bybit strategy using their unique environment URL setup, it took me a while to wrap my head around it. Yes, Jigar Suthar, even after I read the documentation and still created a few API keys using the wrong url after checking the documentation more than once.
This place is for helping every level of developer, from beginners to highly experienced, hell, even those few developers who know everything about every coding language and only need to read the documentation once to understand every possible way to use it in every instance possible.
But don't let those condescending few keep you from posting your questions!

Well, you can use linear regression for this to check that there is a correlation between the x and y values. With the library scikit-learn you can make a linear regression model and plot the data with the library matplotlib.
PyInstaller DOES NOT compile Python programs into machine code per se; rather, it creates an executable program that contains a copy of the Python interpreter and your script.
As such, these programs tend to be fairly large. Even a simple “Hello, world” program compiled with PyInstaller can be close to 8MB in size, literally a thousand times larger than a version written in assembly language.
This happens because the coercion is in an unexpected place: The h here is interpreted as h : ((i.val : Fin 3) / 3).val = i.val / 3, so you get ((6 : Fin 3) / 3).val = (0 / 3).val = 0. On newer versions of Mathlib, the coercion from Nat to Fin is disabled by default to avoid such unintuitive behavior (but you can enable it using open scoped Fin.NatCast).
So, I was having the same issue. When I checked the Departments table in the database, the ConcurrencyToken field was populated with a GUID of 00000000-0000-0000-0000-000000000000. This was due to the EF migration builder creating a default value for the GUID field in the Up() method. Check your <Timestamp>_RowVersion.cs file for this.
Being a newbie, I didn't know how to manage this. I just decided to run the following commands to drop the DB and create a new migration
drop the database: dotnet ef database drop
Delete all files in the Migrations folder of the project
create a new migration: dotnet ef migrations add <Migration name>
Update the database: dotnet ef database update
Then build and run your application. You should notice that a unique GUID is created for each department or whatever entity set you are applying the GUID field to.
In hindsight, I think removing the default value line in the <Timestamp>_RowVersion.cs file would have worked, but I didn't think that through since I was so frustrated. So, try that first before dropping the database, and please let me know if that worked.

Is there any reason you would not record your screen with an external program? It worked fine for me.
Saving screenshots is possible like described in a github issue. I adopted it for me
def base64_to_image(base64_string: str, output_filename: str):
"""Convert base64 string to image."""
import base64

if not os.path.exists(os.path.dirname(output_filename)):
os.makedirs(os.path.dirname(output_filename))
img_data = base64.b64decode(base64_string)
with open(output_filename, "wb") as f:
f.write(img_data)
return output_filename
...
result = await agent.run()
print(result)
screenshots = result.screenshots()
number_screenshots = 0
for next_screenshot in screenshots:
number_screenshots=number_screenshots+1
path = f"./screenshots/{number_screenshots}.png"
img_path = base64_to_image(
base64_string=str(next_screenshot),

)
print(img_path)
Final Update & Solution
A big thank you to everyone who provided suggestions! After extensive testing based on your feedback, I've finally identified the root cause of the ~8 second cold start time.
The bottleneck was the database connection to the PostgreSQL instance running inside WSL2.
The Experiment
Following the advice to isolate variables, I tried switching the database connection to a different instance:
I set up a new PostgreSQL instance running directly on the Windows host.
I also tested with a local SQL Server Express instance running on Windows.
The results were immediate and dramatic. When connecting to either of the native Windows database instances, the initial application load time dropped to a perfectly normal 200-300 milliseconds. The 8-second delay completely vanished.
This proves that the issue was not with EF Core's model compilation time, nor was it with the Blazor Server framework's JIT compilation. The entire ~8-second delay was being consumed by the initial database connection (dbContext.Database.CanConnectAsync()) from my Blazor app on the Windows host to the PostgreSQL server inside WSL2.
While using localhost to connect from Windows to WSL2 works, it appears to have a significant performance overhead for database connections in this scenario, leading to an unexpectedly long initial connection time that mimics a framework cold-start issue.
I also recall that to resolve other unrelated network issues in the past, I had modified the MTU size inside my WSL2 instance by adding the following command to my ~/.bashrc file:
RDMA-capable NICs enable kernel bypass by setting up direct communication channels between user-space applications and the hardware with shared memory region in the application memory space.
Setup (Kernel): The kernel maps shared memory regions (Send Queues/SQs, Completion Queues/CQs) and "doorbell" registers directly into user space.
Send (User-Space): Application writes Work Requests (WRs) to the SQ, then signals the NIC via a memory-mapped doorbell write (no syscall). The NIC uses DMA to fetch WRs and data directly from host memory.
Completion (User-Space Fast Path): NIC writes Completion Queue Entries (CQEs) to the CQ. The application polls the CQ directly for status (no syscall again...).
This allows zero-copy, low-latency data transfer by using DMA and direct hardware signaling, bypassing the kernel for data path operations.
Thank you @GordonDavisson and @choroba in the comments!
The output of kscreen-doctor is colorized, which means that grep sees a lot more than what comes across in a copy/pasted terminal dump. Instead of colors, it sees "a bunch of junk" that messes up the match, as | LC_ALL=C cat -vt on the end shows:
That is what grep actually sees, and so the search string needs to account for it. One way to do that is to forbid a character instead of requiring one:
It shows part of the formatting that is normally hidden (the m before connected), but that's okay for me because it's in a script that only cares about the exit code. If you care about stdout, then there's some more work to do.
I have calculated that the offset is 120 until you overwrite the return address/eip. The exploit code has the issue, that you have to put the return address which points into your NOP sled as well into your string. It's completly missing.
It could look something like this:
¦ NOP ¦ Shellcode ¦ EIP overwrite
Where NOP and shellcode are 120 characters and EIP overwrite is an address inside the NOP block.
2025. None of the above solutions, rearranging Android Studio and everything else helped me. I just deleted all the DNS settings that I had in Settings -> Wi-Fi -> Details - DNS and my mac automatically created two 8.8.8.8 and 1.1.1.1 and only then after Cold Boot everything started working
@rozsazoltan's way of setting variant doesn't work for automatically inheritable properties, like text color. It will break the utility in dark mode unless your text color utility is applied to the direct parent of the text. The example introduced in Tailwind v4 official doc tries to define background color variants, which is fine.
yes ,if you call method/function in the template ,it can lead to call the method/function many times because Angular runs change detection frequently, re-evaluating the method on every cycle. it can lead to performance issues as well on larger code bases.
As in your case getTitle() functions will execute on every change detection cycle, even if their inputs don’t change. We should avoid calling method/function directly in templates.
Check the version of postgres-client when the elt_script starts initialization.
I had encountered the same issue and resolved by changing the image of source_postgres and destination_postgres to the version my elt_script container is using.
So I have somewhat fixed the issue. I cut down the script and have left the PowerShell window open. Now it doesn't open another instance of the script unless the PowerShell window closes. basically, it sits in the background of the desktop while msedge overtakes it, which is fine for now. The problem now is getting the window to close once msedge closes, so I need to set a condition of some sort for that.
For some strange reason, even though the TText is set to Align=Client and a child of the TRectangle, somehow during the rotation process, the Width was set to less than the width of the TRectangle, hence it appears off. I manually set the `TText` width to that of the rectangle again (even though by right, Align=Client of TText does not require to set width or height). It just resolved the problem.
Why is it Happening : Advertisers can target specific regions, platforms and user profiles based on business relevance, which can sometimes result in lower availability of Ads for a particular region or user profile. Error code suggests that the implementation is correct, and that the Ad Request was not filled because of lack of availability of a suitable Ad at that particular instant of time when an Ad Request was sent from the app.
Opening MainPage in Designer and adding a handler for the Loading event of the button solved the problem. The initialization of the button can be done in the handler.
I spent a day trying to fix this and found out it’s not really a problem. When you create a custom extension for authentication using the TokenIssuanceStart event and connect it to your app, you might see this error when first time you run the user flow. But if you wait a few minutes and try again, the error goes away. So it’s not a real issue — Entra ID just needs some time to update the changes after the first time execution of TokenIssuanceStart event.
You can install the Resizable virtual device, with which you will be able to test for tablet, foldable phone, and so on. To download it, you can proceed as you do for a usual virtual device via the device manager tool.
To recognize a new Spring Boot project in your IDE and get the blue icon, locate its pom.xml file. Right-click on it, and from the context menu, choose "Add as Maven Project." This action tells your IDE to import the project as a Maven module, enabling it to correctly identify it as a Spring Boot application and manage its dependencies.
Could this also be related to how the frontend handles the redirect after a successful login? I'm wondering if the server action finishes before the browser has a chance to store the cookies, especially when working in development mode without HTTPS. Has anyone seen this behavior when testing locally with Next.js server functions?
I'm in the same situation here. I have installed superset 4.1.2 in python virtual environment on redhat 8.8. My analytics database is Clickhouse and I want to enable Jinja templating for filtering based on logged in user and dynamic filtering on the dashboard. My understanding to enable Jinja templating in superset with Clickhouse is that I need to set Two things.
It was my environment issue. I had Calico CNI earlier and swapped to Cilium, but iptables still had some calico rules. I did some tweaks, restarted all the nodes and it works.
I'm pretty certain only variables prefixed with NEXT_PUBLIC_ are swapped out at build time for their corresponding values. Try renaming it to NEXT_PUBLIC_CURRENT_ENV.
I'm very late to respond on this one, but I struggled with this just yesterday for many hours. My password had a dollar sign and I had to esape it with a single back slash. I changed the $ to \$ in the password field and everything worked fine.
Hello you can try using the pivot() function which will allow you to transform the 'Product' column into new columns, while keeping 'Date' as the index.
Just solved it. I was encountering a `caught in Promise` error and I was thinking everything was working fine, just a routing issue. Turns out the browser memory cache was just playing at me. my bad
@Vikas solution only works for LongTensors. Here is an efficient version which works for any dtype:
import torch
def batch_histogram(scores, num_bins, eps=1e-6):
"""
Compute histograms for a batch of score arrays.
Args:
scores (torch.Tensor): Input tensor of shape (batch_size, num_scores)
containing the values to histogram
num_bins (int): Number of histogram bins
eps (float, optional): Small epsilon value to prevent division by zero.
Defaults to 1e-9.
Returns:
torch.Tensor: Histogram tensor of shape (batch_size, num_bins)
where each row contains the bin counts for the
corresponding input row
Example:
>>> scores = tensor([[ 0.7338, 1.2722, -1.0576, 0.2836, -0.5123],
[ 1.0205, -0.6672, -1.0974, -0.1666, -0.6787]])
>>> hist = batch_histogram(scores, num_bins=3)
>>> hist
tensor([[2., 1., 2.],
[3., 1., 1.]])
Note:
This is equivalent to:
torch.stack([torch.histc(scores[i], bins=num_bins) for i in range(scores.shape[0])])
but is more efficient for batch processing.
"""
batch_size = scores.shape[0]
# Initialize histogram tensor and ones for counting
hist = torch.zeros((batch_size, num_bins), dtype=scores.dtype, device=scores.device)
ones = torch.ones_like(scores)
# Find min and max values for each batch element
batch_min = torch.min(scores, dim=1, keepdim=True)[0]
batch_max = torch.max(scores, dim=1, keepdim=True)[0] + eps
# Normalize scores to [0, 1] range
normalized_scores = (scores - batch_min) / (batch_max - batch_min)
# Convert to bin indices (floor)
bin_indices = (normalized_scores * num_bins).long()
# Accumulate counts in histogram
hist.scatter_add_(1, bin_indices, ones)
return hist
You might want to include bin_indices = torch.clamp(bin_indices, 0, num_bins - 1) after getting the bin_indices in order to avoid out-of-bounds errors.
I appreciate the responses from everyone but Flet documentation provides an easy way to make changes to AndroidManifest.xml by making changes in your pyproject.toml
just add the following block in your pyproject.toml
In my case I updated the primng to version 19, but my primeflex was still at 3.2.2, I updated the primeflex to version 4.0.0 and styles started working again. See the guide https://primeflex.org/installation
The guide about migrating to Express 5 instructs to replace app.get('/*') (v4) with app.get('/*splat'), to match any path without the root path. To match the root path as well, use /{*splat}.

Get Default Value for DropDownListFor from database
-1
I coded a website to collect student information including 3 dropdown lists: Province, District, Ward. When I create a new student, I get the Province, District, Ward data from the database to enter each DropDownListFor very well, but when I go to the function of editing student information, I don't know how to get the data from the previously saved database to enter each DropDownListFor.
I use ASP.NET Core MVC and Html Helper to do it. I hope you can guide me.

I think you have not asked your question correctly as some of the statements in it does not make any sense. If your question is how you can have resource group in one location and the resources in it in another location than the answer is the following:
Resource group is container resource. Meaning that it serves the purpose of containing other resources in it. Those resources that are contained within the resource group does not inherit its location. Generally resources that share the same lifecycle are put in the same resource group. It is highly recommend though that the resources in the resource group have the same location. This is due to the resource group containing metadata about the resource in it. In case there is ongoing issue in certain Azure location you might not be able to update/apply settings to the resources which are located in resource group of that location even when the resources itself are in another location.
