> navigaten opertaion not permitted R studio
so waht u have to do
- open R studio
- you may find RStudio next to apple icon Click over there
- Then click on Service setting
- Then Click on Accessibility
and then
- Click on Restore default
Now when u open R studio again it will ask
to all permission for folder etc
- click allow

This is the simplest example I can think of.
import vlc
import time
instance = vlc.Instance('--no-xlib --quiet --sub-source=marq')
player = instance.media_player_new()
media = instance.media_new("/home/rolf/BBB.ogv")
player.set_media(media)
player.video_set_marquee_int(0, 1) #Enable
player.video_set_marquee_int(6, 48) # size in pixels
player.video_set_marquee_int(4, 8) # position | bottom
player.video_set_marquee_int(7, 0) # timeout
#player.video_set_marquee_string(1, 'First marquee String') # using a fixed parameter
player.video_set_marquee_string(vlc.VideoMarqueeOption.Text, 'First marquee String') # using the vlc function
player.play()
for iter in range(45):
if iter == 15:
player.video_set_marquee_string(1, "Marquee Changes") # new text
if iter == 30:
player.video_set_marquee_string(1, "Final Marquee Change") # new text
time.sleep(0.5)
> I get NameError: name 'VideoMarqueeOption' is not defined
That is because `VideoMarqueeOption` is a function in vlc.py that converts a named option to a number.
You will have a similar problem with `Position`.
So either use the vlc function i.e. `vlc.VideoMarqueeOption` or a fixed parameter e.g. 1
At this point I dash your hopes and refer you to either the vlc documentation or vlc.py for a full list of the options and their number equivalents. :) |
I am writing a game with python on a MAC PC and I am getting the following error:
`libc++abi: terminating due to uncaught exception of type NSException`
The [SnakeGame](https://github.com/GaiAshk/SnakeGame/tree/main) is written so the player can be able to run using [pygame](https://www.pygame.org/docs/) or [turtle](https://docs.python.org/3/library/turtle.html).
The game is working just fine when running it with pygame, but when switching to turtle I get this error:
```

**Here is the best way to install GMP and eclipse**
Follow this link
http://www.multigesture.net/articles/how-to-install-mingw-msys-and-eclipse-on-windows/
You need to make sure of the following that hasn't been mentioned there:
When installing MinGW choose a path that contains no space like "c:\MinGW"
Once installed, From **start** open **MinGW installation manger**
- choose all the basics
-then under MinGW, choose all GMP libraries to be installed
- Apply changes
After that you will install JDK, then Add "C:\Program Files\Java\jdk1.8.0_121\bin" to PATH system variable
After installing Eclipse go to:
- GCC C++ compiler --> Miscellaneous add -lgmp -lgmpxx to the END of the line
- MinGW C++ linker --> Libraries Add to the "Libraries (-l)" both gmp and gmpxx IN THAT ORDER

I'm trying to utilize PortAudio in a Unreal Engine 5 project. Just started learning to use this API.
I encountered a weird problem when looking at the available devices. All device names are in chineese(?). I can't figure out why that is. How do I fix this?
[![get device info results][1]][1]
Don't know if this is useful info, but: I'm on Windows 11. My display language is English. My keyboard language is German. And those are the only language packs I have installed.

Your question is probably opinion-based, as no one will be able to give you a definitive answer or a guarantee that the code you are using is going to be stable, even when requiring `@ExperimentalApi`. <br> I can only share my thoughts and experience.
-----------------
At the current point, basically everything in Jetpack Compose [`material3`][1] libraries needs to be marked as [`@ExperimentalApi`][2]. However, while these APIs might change in the future, in my experience they are stable in a sense of having no bugs when you go with a stable release. <br> Check out which dependency version is considered as the latest stable in the respective dependency page.
[![release table][3]][3]
Also, it seems like the Jetpack Compose team is rather quickly using this annotation as sort of a safety precaution. Even components like [`BottomAppBar`][4] which API has been stable for a long time are still requiring an `@ExperimentalApi` annotation.
So I would say, you can use it in production, but be aware that when you update the dependencies once in a while, it can be that you will have to rewrite some code. <br> I recently updated a project that I wrote two years ago, and it took two hours to refactor all the changed APIs. For me, this is acceptable.
I'd suggest if you have doubt on using a specific experimental Composable, check out the [Google Issue Tracker][5] and search for that Composable. This will give you a quick hint whether there are many or severe bugs occuring with that Composable.

I am a Android application developer, I have implemented a chat feature in my app. I want to integrate the stickers/gifs available in the soft keyboard into my app's chat interface, similar to how WhatsApp and IMO handle it.
Even if a user uses any soft keyboard like Gboard or Google AI Keyboard, apps like WhatsApp still allow users to add stickers from those keyboards to their chats. I want to implement similar functionality in my app.
I need code to load stickers/gifs from the soft keyboard into an Imageview using android studio java language. Could you provide me with the code for this, or explain how to implement it? I have attached screenshots for reference.

I know that there are similar questions but none of them solved my problem.
I checked the networks and containers are running in the same network. I can also connect to mysql container through localhost when the spring app is running locally but it fails when I try to run it in the container and change the host name to my mysql service. I looked at several examples and tried changing the host name but nothing worked.
Is there anything wrong with my setup? Any help is appreciated |

From an arm64 mac machine - Im trying to package an Electron-forge app that will work both on an arm64 and x64 architectures.
I tried to use the @electron/universal npm package but couldt nake it run.
Their docs arent great.
From some reference i found
i added this to my package.json

"packager": {

}
runing "npm run package" outputs only an arm64 version.
any suggestions? |
I am trying to make a measurement using the CAEN DT5742 16-channel digitizer using the library [CAENPy](https://github.com/SengerM/CAENpy/blob/main/CAENpy/CAENDigitizer.py) which is basically just a wrapper around the actual [CAENDigitizer](https://www.caen.it/products/caendigitizer-library/).
My program scans an area with a laser using stepper motors and reads out the data coming from an analog readout board via the digitizer.
It's been working more or less well, but I noticed that my program randomly becomes unresponsive and 2 processes (my program is multiprocessed) draw 100% CPU (single core).
The code I use for acquiring data with the digitizer:
```python
def read_and_save_events(self, max_num_events: int = 1):
"""Reads a specified number of events from the digitizer.
Arguments
---------
max_num_events: int, default 1
Number of events to read.
Returns
-------
nevts: int
Number of events read.
"""
nevts: int = 0
data = []
retries = 0
while retries < MAX_RETRIES:
retries += 1
try:
with self.device:
self.log.info("Reading %d events...", max_num_events)
while nevts < max_num_events:
time.sleep(0.05)
waveforms = self.get_waveforms()
current_nevts = len(waveforms)
nevts += current_nevts
data += waveforms
self.log.info(
"Read %d out of %d events...", nevts, max_num_events
)
break
except RuntimeError:
self.log.error("Encountered error during read. Retrying...")
self.hard_reset(self._device_id)
self.close()
self.device = CAEN_DT5742_Digitizer(self._device_id)
self.init()
time.sleep(RETRY_TIMEOUT)
else:
self.log.error("Too many retries, aborting read...")
if self._save_path is None:
self.log.warning("No save path specified, waveforms not saved!")
return 0
# Disentangle data and save to file
df = pd.DataFrame(data)
timestamp = datetime.datetime.now().strftime("%Y%m%d_%H%M%S")
data_file = os.path.join(self._save_path, f"waveforms_{timestamp}.h5")
self.curr_savefile = data_file
with pd.HDFStore(data_file, "w") as store:
for channel in df.columns:
channel_df = []
for eventid, event in enumerate(df[channel]):
event_df = pd.DataFrame(event)
for column in event_df.columns:
col = pd.Series(
event_df[column].values,
name=f"{eventid}_{column.split()[0]}",
)
channel_df.append(col)
channel_df = pd.concat(channel_df, axis=1)
store.put(channel, channel_df)
```
I profiled the program using `py-spy` and got the attached call stack for one of the heavy duty processes. So, apparently the problem is with the `_GetNumEvents` method from the library.
My question: Can I even solve this bug? If not, how would I monitor my program to get out of this error state? |

* `glPushMatrix()` just pushes the current matrix value onto the stack existing somewhere.
* This is used to saving the current matrix value.
* **This function does not cause any changes to the current matrix**.
* `glPopMatrix()` pops the matrix value from top of the stack, and current matrix value is overwritten with this popped value.
* This is used to loading the matrix value previously pushed.
This is the all.

I have a circle that follows my cursor. I was wondering if I can add an effect so when the circle hovers over the text it inverts only the text so you are able to see the text even when the white circle is on top of it.
I have tried to make the text black when I hover over it using CSS but it wont work because the words are too big so the text out of the circle blend in with the background.

Suggestions to consider for your my.cnf [mysqld] section.
Zaki,
General Log is NORMALLY not ON.
Until actually needed and will be used,
general_log=OFF
When needed from MySQL Command Prompt,
SET GLOBAL general_log=ON
then when you have sufficient logging completed, usually less than one minute - unless you have a VERY LONG executing process,
SET GLOBAL general_log=OFF
to avoid filling you storage with information you will NEVER look at.
Trust me a full storage device is NO FUN to deal with.
Do you have a REAL good reason for setting innodb_page_size anything
other than the default of 16384?
Consider editing your my.cnf to get back to the default from 64K
This has helped the few instances where they have attempted anything
other than 16384 and been troubled with incidents out of nowhere.
Additional suggestions will be provided after posting the additional information requested in a comment above.

**Is there a way to know if the camera is on?**
There be no straight way for an Android app to detect if another app is using the camera. Android's security model prohibit one app from accessing the resources or monitoring the behavior of another app without explicit permission and appropriate APIs.
While Android does provide APIs for accessing certain system information, such as the list of running processes or the usage statistics of other apps, these APIs have limitations and privacy considerations. They may not provide fine-grained information about whether a specific app be actively using the camera at any given moment.
Furthermore, even if you could detect that another app be using the camera, accessing or interfering with its operation would likely be a violation of the Android platform's security principles and may lead to ur app being flagged as potentially harmful or intrusive.
If have concerns about privacy or resource usage related to the camera, it be best to address them within your own app's functionality and not attempt to monitor or interfere with other apps' behavior. Additionally, if believe an app be misbehaving or violating user privacy, can report it to the appropriate platform or store for investigation.
**Is there a way to disable the camera?**
Disabling the camera programmatically on Android be not a straightforward task, especially considering Android's security model, which prioritizes user privacy and app sandboxing. System-level permissions be typically required to manipulate hardware features such as the camera, and such permissions be not available to third-party apps for security reasons.
However, if you have control over the device's firmware or system settings (for example, if ye be developing a custom ROM or managing devices in an enterprise environment), may be able to disable the camera through device policies or modifications to the system software.
Here be some potential approaches to consider:
Device Administration: Device Administration APIs to enforce policies on Android devices, including disabling certain features such as the camera. However, this requires the app to be designated as a device administrator, and users must grant permission for these privileges.
Custom ROMs: If developing custom firmware for Android devices (e.g., custom ROMs), you may be able to modify the system settings or firmware to disable the camera functionality. This approach requires advanced knowledge of Android system development and may not be feasible for all devices.
Enterprise Device Management: In enterprise environments, mobile device management (MDM) solutions can be used to enforce policies on managed devices, including disabling certain hardware features like the camera. MDM solutions typically provide APIs or management consoles to configure device policies remotely.
Rooting: Rooting an Android device provides superuser access, allowing for deeper system modifications. With root access, it may be possible to disable the camera through system-level changes. However, rooting voids device warranties and can compromise device security.
It be important to note that disabling critical features like the camera can have significant implications for device functionality and user experience. Additionally, any modifications made to the system software should be done carefully to avoid unintended consequences or security vulnerabilities.
As a general principle, apps developed for the Google Play Store should not attempt to disable or manipulate system features without user consent, as this violates Google's policies and may result in app removal or account suspension.

We are using firebase_messaging for notifications in our flutter app and to customise notification we are using awesome_notifications. The notification ontap flow is working fine in background or foreground state. The problem is in killed state, the callbacks are not working.
used `@pragma('vm:entry-point')` also to awesome_notifications background state listeners.
Also used `getInitialNotificationAction()` method in hope to get event there but its still not working.
Weird part is that the same setup is working on another flutter project. Another observation is that when the firebase's background handler is called in killed state which also has `@pragma('vm:entry-point')`, our main method gets called and due to which `getInitialNotificationAction()` method is also gets called when app is killed.
The callback to work fine in killed state. |

I am using `differential_evolution` from `scipy` with `workers` to parallel the calculations. And I switch to `pytorch` from `numpy` to speed up the code.
```
from torch.multiprocessing import set_start_method,Pool
if __name__ == '__main__':
#device = get_device()
device = torch.device('cpu') # testing with cpu
num_workers=int(sys.argv[1])
set_start_method("spawn",force=True)
pool=Pool(num_workers)
results = differential_evolution(likelihood, seed=np.random.seed(0),workers=pool.map,
callback=print_de, bounds=bounds, maxiter=1500,
disp=True,recombination=0.1,mutation=(0.9,1),
constraints=NonlinearConstraint(positive_definite, lb=0, ub=np.inf),
popsize=25,
polish=False
)
```
In my own laptop (m1 macbook) this works fine either using `torch.multiprocessing` or `multiprocessing` (simply set `workers=int(sys.argv[1])`).
When I test this in HPC with 256 cores in 1 node, it slows down a lot. Using `torch.multiprocessing` is faster than `multiprocessing`, but still one iteration is much slower than when I don't do parallel.
When I use `top`, I can see the correct number of `python` instances are running, but the cpu usage is more than 100%, some even with 1000% per `python`, can this be the problem? When I use `numpy` the cpu usage is almost 100%.
How can I solve the problem? |

It's often needed to patch and compile a HTML (in my case a SVG) returned from a backend.
I used only the simplest version as
```
import {compile} from 'vue';
const component = compile(text);
```
But now I patch the source with DOM and inject other components inside it.
For that I need to use `app.component()` to register all the injected components.
That's bad obviously for several known reasons.
Could we inject locally imported components? Like:
```
import Tooltip from 'Tooltip.vue';
import {compile} from 'vue';
const component = compile(text, {components:[Tooltip]});
```
Definitely `compile` has an extensive set of options:
https://github.com/vuejs/core/blob/fef2acb2049fce3407dff17fe8af1836b97dfd73/packages/compiler-core/src/options.ts
But I can't find anything about injecting components.
There are several ideas but need prolonged tries and errors like:
1. Compile as SFC and inject dependencies somehow
1. Provide components in `ctx` somehow on a render
1. Somehow do it with `defineComponent`
But I can't figure a proper direction to follow, any help would be appreciated. |

What I am trying to achieve?
----------------------------
Use System.Text.Json in my VSTO Addin, which has worked recently but stopped to work when I upgraded RestSharp
What is the problem?
--------------------
2 Exceptions while running the VSTO Plugin in Debug Mode in Outlook:
First:
FileNotFoundException: Die Datei oder Assembly "System.Text.Json, Version=8.0.0.2, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51" oder eine Abhängigkeit davon wurde nicht gefunden. Das System kann die angegebene Datei nicht finden.
Second:
FileNotFoundException: Die Datei oder Assembly "System.Text.Json, Version=7.0.0.2, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51" oder eine Abhängigkeit davon wurde nicht gefunden. Das System kann die angegebene Datei nicht finden.
So in short:
Neither version of System.Text.Json can be found. 8.0.0.2 and 7.0.0.2
My setup:
--------
Visual Studio 2022 with latest updates.
Project setting:
[![enter image description here][1]][1]
[![enter image description here][2]][2]
And yes I realized that 7.0.2 != 7.0.0.2
This is how Nu Packages admin for the Project looks like when I hit:
[![enter image description here][3]][3]
[![enter image description here][4]][4]
and yes I already tried to upgrade to 8.0.2 but this delivered the same result by:
[![enter image description here][5]][5]
still the same problem
What I also already tried:
---------------------
I changed my target framework and found the hint that changing the target framework may influence the installed packages (this is the link provided my VisualStudio 2022: https://learn.microsoft.com/en-us/nuget/consume-packages/reinstalling-and-updating-packages) . Thus I remove RestSharp and System.Text.Json. Then searched for RestSharp, found out that it in the current stable version 110.2.0 depends on at least .Net Framework 4.7.1. Thus I switched to .Net Tartgetframework 4.7.1 in my project setting like this:
[![enter image description here][6]][6]
Then added RestSharp. Which my itself installed System.Text.Json 7.0.2
[![enter image description here][7]][7]
The exception still stays the same:
Exception 1:
FileLoadException: Die Datei oder Assembly "System.Text.Json, Version=8.0.0.2, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51" oder eine Abhängigkeit davon wurde nicht gefunden. Die gefundene Manifestdefinition der Assembly stimmt nicht mit dem Assemblyverweis überein. (Ausnahme von HRESULT: 0x80131040)
Exception 2:
FileLoadException: Die Datei oder Assembly "System.Text.Json, Version=7.0.0.2, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51" oder eine Abhängigkeit davon wurde nicht gefunden. Die gefundene Manifestdefinition der Assembly stimmt nicht mit dem Assemblyverweis überein. (Ausnahme von HRESULT: 0x80131040)
At least it is a minor improvement as the error message changed from:
File not found to The manifest definition of the assembly found does not match the assembly reference. (Exception from HRESULT: 0x80131040)
What I still don't get is that RestSharp depends in 7.0.2 but the Exception tries to find 7.0.0.2. Please note **7.0.0.2 != 7.0.2** is it?
So i investigated my Project csproj file:
and found for RestSharp:
<Reference Include="RestSharp, Version=110.2.0.0, Culture=neutral, PublicKeyToken=598062e77f915f75, processorArchitecture=MSIL">
<HintPath>..\packages\RestSharp.110.2.0\lib\net471\RestSharp.dll</HintPath>
</Reference>
and for System.Text.Json:
<Reference Include="System.Text.Json, Version=7.0.0.2, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51, processorArchitecture=MSIL">
<HintPath>..\packages\System.Text.Json.7.0.2\lib\net462\System.Text.Json.dll</HintPath>
</Reference>
--> Question: Is that correct?
I investigated whether there is the dll available:
[![enter image description here][8]][8]
The answer is yes?

New to go. This is currently my code:
```
client := http.Client{
Timeout: 10 * time.Millisecond,
}
resp, err := client.Get("http://google.com/")
if err != nil {
if os.IsTimeout(err) {
fmt.Println("There was a timeout")
}
panic(err)
}
```
This works, but os.IsTimeout writes:
```
// This function predates errors.Is, and the notion of whether an
// error indicates a timeout can be ambiguous. For example, the Unix
// error EWOULDBLOCK sometimes indicates a timeout and sometimes does not.
// New code should use errors.Is with a value appropriate to the call
// returning the error, such as os.ErrDeadlineExceeded.
```
```
if errors.Is(err, os.ErrDeadlineExceeded) {
fmt.Println("There was a timeout 2")
}
```
Which doesn't work. I tried debugging, but there wasn't an easy way for me to see how to check for the specific error type. Coming from.NET I could directly see the exception type, and check for that, how do I go about this in the future? |

Note the difference:
- `[1]` selects the second element of a series, equivalent to `.iloc[1]`. Since the series is a series of lists of substrings created with `.str.split()`, it results in a single **list** of substrings.
- `.str[1]` selects the second string of a list of substrings, row-wise. It results in a **series** of substrings.

You cannot mock `String` with Mockito. It has nothing to do with it being `final`, as Mockito has been able to mock final classes since 2.0, and natively since 5.0.
If you attempt it with the latest version, you get this `MockitoException`:
> Cannot mock/spy class java.lang.String
> Mockito cannot mock/spy because :
> \- Cannot mock wrapper types, String.class or Class.class
This is [by design][1].
> This is working as intended. You can't mock strings. Use a real string instead.

I have a very simple Asp .Net API project where I am trying to add some trace logging.
I need some help with Application Insights configuration for that logging.
Right now its capturing ALL traces while in *appsettings.json* I have set the **Default** level to **Information**.
I have this code in my *Program.cs*
`services.AddApplicationInsightsTelemetry();`
Followed by:
`Trace.Listeners.Add(new Microsoft.ApplicationInsights.TraceListener.ApplicationInsightsTraceListener());`
And the following in my *appsettings.json*:
`"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft": "Warning",
},
"ApplicationInsights": {
"LogLevel": {
"Default": "Warning",
"Microsoft": "Warning"
}
}`
I am expecting that only traces with level *Information* or above should get logged to Application Insights however I am also seeing every thing getting logged to Application Insights.
What do I need to do change the trace logging level globally? |

**While k8s itself does not provide a specific API for file IO operations. Applications can communicate with PV in a standardized and scalable way due to its strong infrastructure for managing storage resources through PVs and PVCs.**
So Persistent Volumes are the suggested method in this case, thus you are on the correct path for applications operating on K8s that require persistent storage for file IO.
**As per official kubernetes doc on** [**Persistent volumes**][1] and **PVCs** :
Pods consume node resources and PVCs consume PV resources. Pods can request specific levels of resources. Claims can request specific size and access modes. Pods use PVCs to define their storage requirements, which are then bound to PVs that are available.
Kubernetes resources stand for persistent storage resources that the cluster has access to AWS EBS, GCP persistent disk, local storage, NFS and cloud storage providers are some of the technologies that can support PVs external storage.
Choose the appropriate PV storage class based on your application performance capacity and cost requirements. As per **David Maze** suggestion, also try to avoid manually establishing StatefulSets or PersistentVolumeClaims and instead use an **external storage**. Perhaps a nice fit would be an object-storage system such as **MinIO** (or) a comparable cloud system like AWS S3). Keeping data in local files can cause issues if you wish to have several copies of a pod in the future.

The problem is that you have `print` statements *during* the reversal process. That reversal will temporarily create cycles, and if in that state you call `print`, which calls `__repr__`, you'll get into an infinite loop.
The solution is to not call `print` with a *node* as argument while you reverse your list (as you already discovered), at least not when the list temporarily has a cycle.
That temporary cycle is created when you do `head.next.next = head`, and is broken again when you do `head.next = None`. It might be a good idea to perform a tuple assignment, so that there is no more moment (in your Python code) where the list has this cycle:
head.next.next, head.next = head, None
