hi here is my code which is used to convert docx to pdf `$pythonPath = '/usr/bin/python';
$unoconvPath = '/usr/bin/unoconv';
$command = sprintf(
'"%s" "%s" -f pdf "%s" 2>&1',
$pythonPath,
$unoconvPath,
$docx_file_path
);
exec($command, $output, $return);
if (is_array($output) && !empty($output[0])) {
throw new Exception(json_encode(implode('; ', $output), true));
}
return true;`
the image is visible when downloading docx using phpword with setImageValue function
$document = new \PhpOffice\PhpWord1\TemplateProcessor($docx_temp_file_path);`
$value = '/www/wwwroot/vss/webrootimages//b6e176e4b84968f6cda8d28b17394bf2.png';
$document->setImageValue($key, $value);
the image is not visible when i convert docx to pdf |
I'm trying to get my first Laravel project running with a freshly installed SQL Server instance, and my normal connections work. However, in Laravel, I get the error message "could not find driver" when I run the environment server with `php:artisan serve`.

I read a lot of other threads with the same error, but I don't want to use PDO, and I think it's optional, or isn't it? |

We can do that with a [lifecycle precondition][1] in a null_resource
see sample code below
``` lang-hcl
variable "sc1_default" {
type = bool
default = "false"
}
variable "sc2_default" {
type = bool
default = "false"
}
variable "sc3_default" {
type = bool
default = "true"
}
variable "sc4_default" {
type = bool
default = "true"
}
resource "null_resource" "validation" {
lifecycle {
precondition {
condition = (
(var.sc1_default ? 1 : 0) +
(var.sc2_default ? 1 : 0) +
(var.sc3_default ? 1 : 0) +
(var.sc4_default ? 1 : 0)
) < 2
error_message = "Only one sc can be true"
}
}
}
```
You can see I set the `sc3_default` and `sc4_default` both to true just to trigger the error ...
the condition is the core of this validation we are just adding all the true with the help of shorthand if syntax `(var.sc_default ? 1 : 0)` and the total should be less than two, I'm assuming that all false is OK, but if not you can change that logic to check that is precisely one.
a terraform plan on that code will error out with the following message:
``` lang-txt
Planning failed. Terraform encountered an error while generating this plan.

I am working on a streaming application which streams video and audio from a Raspberry Pi. I want to overlay some sensor data on the video and after many attempts with textoverlay I am trying to use imagesequencesrc instead, with the intent of having my sensor script output an image with the sensor data at regular intervals and then displaying that on top of the video with imagesequencesrc.
I have gotten this to work on the Raspberry's desktop with this pipeline:
<gst-launch-1.0 imagesequencesrc location=/home/pi/amazon-kinesis-video-streams-webrtc-sdk-c/build/samples/image-%05d.png start-index=1 stop-index=-1 framerate=1/1 ! decodebin ! compositor name=comp ! autovideosink videotestsrc ! video/x-raw, framerate=\(fraction\)5/1, width=320, height=240 ! comp.>
But in my application I am using the <gst_parse_launch> function as instructed in the Gstreamer documentation, and I just can't get it to work.
I have tried several pipelines, to no avail:
```
pipeline = gst_parse_launch("imagesequencesrc location=/home/pi/amazon-kinesis-video-streams-webrtc-sdk-c/build/samples/image-%05d.png start-index=1 stop-index=-1 framerate=1/1 ! decodebin ! videoconvert ! compositor name=comp !"
"appsink sync=TRUE emit-signals=TRUE name appsink-imageseq autovideosrc ! clockoverlay ! queue ! videoconvert ! video/x-raw,width=1280,height=720,framerate=25/1 !"
"x264enc bframes=0 speed-preset=veryfast bitrate=2048 byte-stream=TRUE tune=zerolatency !"
"video/x-h264,stream-format=byte-stream,alignment=au,profile=baseline ! appsink sync=TRUE emit-signals=TRUE "
"name=appsink-video autoaudiosrc ! "
"queue leaky=2 max-size-buffers=400 ! audioconvert ! audioresample ! opusenc ! "
"audio/x-opus,rate=48000,channels=2 ! appsink sync=TRUE emit-signals=TRUE name=appsink-audio ! comp. !" ,
&error);
```
Results in
```
GStreamer-CRITICAL **: 10:57:36.916: gst_element_link_pads_filtered: assertion 'GST_IS_BIN (parent)' failed
```
Moving the comp. command before the x264 encoding to have compositor merge the imagesequence and video before encoding has the application run without errors, but no video or audio is displayed.
```
pipeline = gst_parse_launch("imagesequencesrc location=/home/pi/amazon-kinesis-video-streams-webrtc-sdk-c/build/samples/image-%05d.png start-index=1 stop-index=-1 framerate=1/1 ! decodebin ! videoconvert ! compositor name=comp !"
"appsink sync=TRUE emit-signals=TRUE name appsink-imageseq autovideosrc ! clockoverlay ! queue ! videoconvert ! video/x-raw,width=1280,height=720,framerate=25/1 ! comp. !"
"x264enc bframes=0 speed-preset=veryfast bitrate=2048 byte-stream=TRUE tune=zerolatency !"
"video/x-h264,stream-format=byte-stream,alignment=au,profile=baseline ! appsink sync=TRUE emit-signals=TRUE "
"name=appsink-video autoaudiosrc ! "
"queue leaky=2 max-size-buffers=400 ! audioconvert ! audioresample ! opusenc ! "
"audio/x-opus,rate=48000,channels=2 ! appsink sync=TRUE emit-signals=TRUE name=appsink-audio !" ,
&error);
```
Using autovideosink instead of appsink to link the imagesequencesrc element to autovideosrc results in a working video and audio stream that is transmitted to the webservice (AWS KVS WebRTC), but the imagesequence is displayed on the Raspberry's desktop in a 1280x720 window, without the video. So the imagesequence is not merged with the video/audio, only rendered locally.
I expected compositor to at least merge the images with the x-raw video before encoding and linking audio, but I was wrong. I have attempted to move the comp. command throughout different stages of the pipeline, but it does not work as intended. I feel like I am just misusing the compositor syntax, but I can't figure it out despite hours in the GStreamer documentation. Grateful for any suggestions or insight. |

I am working on automating a silverlight application and executing it from jenkins.
**Problem:**
I am trying to access the folder "SandboxRefresh" present at the bottom of the page in the silverlight application that I am working on.
**Code below:**
SilverlightElement jobfolder2 = extab
.GetFirstOrDefaultUIElement(criteria.ByName("SandboxRefresh")
.AndByClassName("TextBlock"));
**Issue Observed:**
Executing the above java code in Eclipse resulted in Arithmetic overflow exception as it could not find the element at the bottom of the page.
**Please note:**
I tried many approaches that worked for me in my machine but it did not work on Jenkins.
ex:
Button bt= new Button();
Screen scr= new Screen();
scr.wheel(bt.WHEEL_DOWN, 2);
The above code worked well to scroll to the bottom of the page but it is not always successful. Sometimes the code gets executed but scroll does not happen.
Can anyone help me with an approach to scroll to the desired element in silverlight application when launched the code from jenkins? |

As [documentation](https://github.com/hapijs/joi/blob/master/API.md#anycustommethod-description) said:
> **any.custom(method, [description])**
Adds a custom validation function to execute arbitrary code where:
> - **method** - the custom (synchronous only) validation function using signature function(value, helpers)
In your case, **isUniqueEmail** is not synchronous. I suggest to move your validation in your business layer code.

It should be possible to handle full line reading with keys suppression by taking advantage of [ReadKey(bool intercept)][1] with some custom solution like:
public static string? ReadLine(bool intercept)
{
if (!intercept)

StringBuilder sb = new();
int position = 0;
ConsoleKeyInfo c;
do
{
c = Console.ReadKey(true);
if (!char.IsControl(c.KeyChar))
{
sb.Insert(position++, c.KeyChar);
}
else
{
switch (c.Key)
{
case ConsoleKey.Delete:
if (position < sb.Length)
sb.Remove(position, 1);
break;
case ConsoleKey.Backspace:
if (position > 0)
sb.Remove(--position, 1);
break;
case ConsoleKey.LeftArrow:
position = Math.Max(position - 1, 0);
break;
case ConsoleKey.RightArrow:
position = Math.Min(position + 1, sb.Length);
break;
case ConsoleKey.End:
position = sb.Length;
break;
case ConsoleKey.Home:
position = 0;
break;
default:
if (c.KeyChar == 26) // Ctrl+Z
{
Console.WriteLine(); // End of input. Move to next line
return null;
}
break;
}
}
} while (c.Key != ConsoleKey.Enter);

I created `person` table as shown below:
```sql
CREATE TABLE person (
id INTEGER,
name VARCHAR(20)
);
```
Then, I created `my_func()` which returns a table as shown below:
```sql
CREATE FUNCTION my_func() RETURNS TABLE(id INTEGER, name VARCHAR)
AS $$
BEGIN
RETURN QUERY SELECT id, name FROM person;
END; -- ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑
$$ LANGUAGE plpgsql;
```
Finally, calling `my_func()` got the same error as shown below:
```sql
postgres=# SELECT my_func();
ERROR: column reference "id" is ambiguous
LINE 1: SELECT id, name FROM person
^
DETAIL: It could refer to either a PL/pgSQL variable or a table column.
QUERY: SELECT id, name FROM person
CONTEXT: PL/pgSQL function my_func() line 3 at RETURN QUERY
```
So, I set the table name `person` with `.` just before `id` and `name` as shown below:
```sql
CREATE FUNCTION my_func() RETURNS TABLE(id INTEGER, name VARCHAR(20))
AS $$
BEGIN
RETURN QUERY SELECT person.id, person.name FROM person;
END; -- ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑
$$ LANGUAGE plpgsql;
```
Finally, I could call `my_func()` without error as shown below. *Omitting `FROM` clause from [SELECT statement][1] gets [the error][2]:
```sql
postgres=# SELECT my_func();
my_func

I want to get live weather data with web scrapping. But I'm facing a problem I can not find the solution for.
I was thinking about using BeautifulSoup for this.
<span class="Column--precip--3JCDO">
<span class="Accessibility--visuallyHidden--H7O4p">Chance of Rain</span>
3%
</span>
I want to get the 3% out of this container. I already managed to get data from the website using this code snippet for another section.
temp_value = soup.find("span", {"class":"CurrentConditions--tempValue--MHmYY"}).get_text(strip=True)
I tried the same for the rain_forecast
rain_forecast = soup.find("span", {"class": "Column--precip--3JCDO"}).get_text(strip=True)
But the output my console is delivering is: "--" for print(rain_forecast).
The only difference I can see is, that between the "text" that should be get from the span, there is another span.
Another way I came across stackoverflow is to use Selenium, because the data has not yet been loaded into the variable and therefore the output is "--".
But I don't know if this is overkill for my application, or if there is an simpler solution for this problem.

I'll start by saying that I'm not a Java expert, and I'm facing a really strange problem that I'm not able to solve.
I'm working on an application to which I decided to add a telegram bot in order to give some remote information. When I run the application from the IDE (currently I'm using IntelliJ IDEA) all works fine, as soon as I create an excecutable version of the same application the telegram bot stops to working without throw any exception and I cannot figure out what I'm doing wrong.
Now in order to isolate the problem I created a dummy project that implement only the telegram bot (that I've extracted from the first project) but the behavior is the same: from IDE no problem, from excecutable the bot don't work.
In the following section you can find all the details about the code and all the dependencies that I'm using.
Basically I created a JavaFX project that is made by only one scene whit 2 buttonsç
- **Connect**: used to open the connection with the telegram bot
- **Send**: used to send a "Test" message over the bot channel.
[Application View](https://i.stack.imgur.com/i569O.png)
# Code
Here you can find the FX controller class:
```

telegramBot = new TelegramBot("My_test_bot");
welcomeText.setText("Connected");
} catch (Exception e) {
File file = new File("C:\\Users\\luca-\\IdeaProjects\\TelegramBotUI\\Installer\\ConnectException.txt");
file.createNewFile();
PrintWriter pw = new PrintWriter(file);
e.printStackTrace(pw);
}
}
@FXML

try {
telegramBot.sendMessage("Test");
welcomeText.setText("Sent \"Test\"");
} catch (TelegramApiException e) {
welcomeText.setText("Excetion!!");
fireAlarm(Alert.AlertType.ERROR, HelloApplication.stage, "Error", "Connection Info not set!", e.getMessage());
File file = new File("C:\\Users\\luca-\\IdeaProjects\\TelegramBotUI\\Installer\\TestButtonException.txt");

PrintWriter pw = new PrintWriter(file);
e.printStackTrace(pw);
pw.close();
}
}

# Excecutable script
In order to generate the excecutable file Im using the following script:
```
jpackage -t exe --name "TelegramBotUI" --icon ".\MyIcon.ico" --input "../out/artifacts/TelegramBotUI_jar" --dest "./" --main-jar "TelegramBotUI.jar" --main-class "com.example.telegrambotui.HelloApplication" --module-path "C:\Program Files\Java\javafx-jmods-17.0.2" --add-modules javafx.controls,javafx.fxml --win-menu --win-dir-chooser
```
Since I didn't catch any exception from the executable version, I tried to save any kind of exception in the txt file if there was one but none was caught.
I think that Im doing some mistakes in the way I generate the excecutable because from the IDE the application works without any problem.

In C# I have a class like this
public class BClass
{
public int Ndx { get; set; }
public string Title { get; set; }
}
This is then used within this class
public class AClass
{
public int Ndx { get; set; }
public string Author { get; set; }
public BClass[] Titles { get; set; }
}
Now when I populate author I do not know how many titles they have until run time so the number of instances of `AClass.Titles` there will be, so my question is how do I initialise this everytime please?
Thanks in advance

I have the following pieces of nodejs code:

});
watcher

// func1();
})
.on('change', path=> {
// func2();
})
.on('unlink', path=> {

});
I need to use mocha to write some unit test cases to test the above code, but I'm not familiar with mocha and not sure how to trigger these add/change/unlink events. I've tried to use mock-fs, but it seems like it can only simulate the 'add' event. Can somebody help me if you have any idea?

// on 'change event

I am trying to subtract a date column from another column which is not a date. Generally, I would use
```select date - interval '3' month from table_name```
This would then give me the date 3 months before the date column but this time around I want the '3' to come from a column within the same table. This column would have different numbers say 3, 4 etc.
I have tried a couple of methods using concatenation but it has not worked. (This is an Oracle SQL developer query)
Edit: Example - I have two columns, one column is a date format and the other is number format with numbers such as 1, 2, 3 and so on. I want to take the date in column 1 for example, 01/Jan/2024 and use column 2 to subtract the months from the date. For example, where the number is 1, the output should return 01/DEC/2023, where it is 2, output should return 01/Nov/2023 and so on |

Found the answer to this issue here : https://litmus.com/community/discussions/5286-mysterious-white-line-in-outlook
Basically, with MSO, you wouldn't want to handle the direction and padding on the same table. Nesting is the key.
So using a mj-wrapper for the padding and then the section for the direction did the trick and the bug disappeared.
```html
<mjml>
<mj-body background-color="red">
<mj-wrapper padding="16px">
<mj-section direction="rtl" background-color="#ffffff" padding="0">
<mj-column vertical-align="middle">
<mj-image src="https://picsum.photos/536/354"></mj-image>
</mj-column>
<mj-column vertical-align="middle">
<mj-text font-size="20px" color="red" font-family="helvetica">text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text </mj-text>
</mj-column>
</mj-section>
</mj-wrapper>
</mj-body>
</mjml>

To achieve the appending of a new row from the column index you want, you must use the Apps Script method [setValues](https://developers.google.com/apps-script/reference/spreadsheet/range#setvaluesvalues) on the right range. Here is the code implementation with self explanatory comments to achieve this:
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
// you can pass a column index to this function as a new parameter (or inside rowData)
function addNewRow(rowData,column) {
const ss = SpreadsheetApp.getActiveSpreadsheet();
const ws = ss.getSheetByName("Recruitment_Contacts");
// Set as the data what we want to insert to then be able to know how many
// columns will this fill
// We need to wrap the data into [] as it is expecting a nested array for [cols] and [rows]
var data = [[rowData.LnRT,rowData.FnRT,rowData.Gn,rowData.St,rowData.Dtr,rowData.Trn,rowData.Td]];
// Set the values on the first row of the sheet (reproducing the behaviour of appendRow)
// and starting from the row index you want (5 for example).
// It will be 1 row and the length of the data
// long in terms of columns.
ws.insertRows(1,1);
ws.getRange(1, column,1,data[0].length).setValues(data);
return true;
}
<!-- end snippet -->

1. Functional. By default, disk is closed when its corresponding handle is (which happens automatically when the program ends). So, the disk was opened (and shown in *Explorer*), but only for a very short period of time (after the *AttachVirtualDisk* call till program end), so you were not able to see it. To be able to use the disk, either:
- Don't stop the program until you're done using the disk (add an *input* statement at the very end)
- Detach the disk lifetime from its handle's one (use *ATTACH\_VIRTUAL\_DISK\_FLAG\_PERMANENT\_LIFETIME* flag from [\[MS.Learn\]: ATTACH\_VIRTUAL\_DISK_FLAG enumeration (virtdisk.h)](https://learn.microsoft.com/en-us/windows/win32/api/virtdisk/ne-virtdisk-attach_virtual_disk_flag)).<br>
Needless to say that now, you'll have to detach the disk yourself, by either:
- Eject it from *Explorer*
- Enhancing code to call *DetachVirtualDisk*
Also, not sure what are the implications of repeatedly attaching the disk (without detaching it)
2. Coding - *Undefined Behavior* generator. Check [\[SO\]: C function called from Python via ctypes returns incorrect value (@CristiFati's answer)](https://stackoverflow.com/a/58611011/4788546) for a common pitfall when working with *CTypes* (calling functions)

Three bugs that I can see, including some spotted in comments.
----
```
MOV AH, 09H
LEA AX, msg3
INT 21H
```
Looks like a typo for `LEA DX, msg3`. As it stands you will have a random value in AH (the high byte of the address of `msg3` and will be executing some random DOS function. That might be what crashes DosBox.
Also, more efficient than `LEA` here (and in the other similar instances) would be `MOV DX, OFFSET msg3` which has the same effect and saves one byte.
----
```
XOR AX, AX
MOV DX, 10H
DIV DX
```
First, you zeroed out `AX` thus discarding the total value you so carefully computed (remember, `AX` emcompasses both `AH` and `AL`). Second, `DIV r/m16` is a 32 by 16 bit division: it divides the 32-bit unsigned value in `DX:AX` by the value in `r/m16`, with the quotient placed in `AX` and the remainder in `DX`. So here you are dividing `100000H` by `10H`; the quotient is `10000h` which overflows 16 bits, and so you will get a divide overflow exception.
This could also be the cause of the crash, though I seem to recall that real MS-DOS had a handler for the divide overflow interrupt that would print a message and terminate the program, without crashing the system. I'm not sure if DosBox provides that, however.
Also, `10H` is hex, so you're dividing by sixteen. I'm assuming you probably wanted decimal output, so you want to divide by ten (`10`) instead.
Thus, I think you probably meant
```
XOR AH, AH ; zero-extend AL into AX
MOV DL, 10
DIV DL
```
to do a 16 by 8 bit divide of the number from `AL` (extended with zeros to produce a 16-bit value in `AX`) by `10H`, placing the quotient in `AL` and the remainder in `AH`.
----
```
MOV AH, 02H
MOV DL, Q
INT 21H
```
You need to add `0` to the values `Q` and `R` to create printable ASCII characters for output. |
If I have the following
```
<AppBar
elevation={0}
>
```
The app bar will be blue. I would like to make that blue transparent while allowing me to update the theme to a different color and still have it show up as that color only with transparency. I tried the following...
```
<AppBar
elevation={0}
sx={{
backdropFilter: "blur(10px)", // Add this line
backgroundColor: 'transparent', // And this line
}}
>
```
But of course this doesn't maintain the theme color and just makes it plain transparent.
Can I make a MUI app bar transparent with the color from the theme still added? |
Can I use a transparrent version of the MUI AppBar with the original color from theme? |
|material-ui| |
First set Bracket pair colorization off `"editor.bracketPairColorization.enabled": false`
then set the color you want.
```json
{
"scope": [
"punctuation.brackets.curly",
"punctuation.brackets.round",
],
"settings": {
"foreground": "#f1bff4",
"fontStyle": "bold"

I am having a problem with low text-to-HTML ratio of pages on wordpress sites.
I could not find a permanent solution in my research.
I use the Wp-Rocket plugin.
I removed unused css codes.
The theme is clean and I use little code.
I used the Fast Velocity Minify plugin to compress html, but it always breaks the site. I tested it on many themes.
Has anyone found a permanent solution?

You can specify eager loading via chaining and also with multiple options together.
So here we load via outer join from User to UserProjectRoleLink to Project. Then we after that query is loaded we lookup the roles via the role ids we fetched in the first query. So this should result in exactly 2 `SELECT` statements.
```python
q = select(
User
).options(
joinedload(
User.user_project_roles
).options(
joinedload(UserProjectRoleLink.project),
selectinload(UserProjectRoleLink.role)
).where(User.id == user_id)
```
There is an example that uses these suboptions here [specifying-sub-options-with-load-options](https://docs.sqlalchemy.org/en/20/orm/queryguide/relationships.html#specifying-sub-options-with-load-options)
As long as you don't reference `project.documents` then the documents should not be eager loaded. Depending on how your serialization works, ie. jsonify, or whatever, you will need to exclude that property.
Then you could dump out your data like this:
```python
return [{
"id": user.id,
"username": user.username,
"project_roles": [{
"project_name": upr.project.project_name,
"project_id": upr.project.id,
"role": upr.role.name,
"role_id": upr.role.id,
} for upr in user.user_project_roles],
} for user in session.scalars(q)]
```
async I think is the same just with a wrapped `await`
`[{} for user in (await session.scalars(q))]` |
I have linked properly the `List-Adapter` and the other `list-item` components.
It didn't getting the `android:id` of `activity_main_cake_items.xml` and giving this error.

For the past few weeks, I've been trying to figure out how to generate platforms just like how they're generated in the Pou minigame "Sky Hop"(Referring to [this game](https://www.youtube.com/watch?v=KAT6dCAM1fw)). I've only succeeded in generating them when I assumed that only one platform can spawn in each row. However, in the minigame I'm trying to replicate, multiple platforms have a chance of spawning (maximum of 3 in the row that can hold 4 platforms, maximum of 2 in the row that can hold 3 platforms), which ruins the current code I have, which you can see below:
```python
import pygame,random
# Initialize Pygame
pygame.init()
# Create a screen object
screen = pygame.display.set_mode((800, 600))
# Define the color of the rectangles
color = (255, 0, 0)
# Define the number of rows and columns
rows = 6
cols = 4
# Define the distance between the rectangles
dist = 10
running = True
# Define the width and height of each rectangle
width = 100
height = 50
platforms = []
platforms_alt = []
seed = []
rng = 0
#test_class
class Platform():
def __init__(self, x,y,width,height):
self.rect = pygame.Rect(x,y,width,height)
def draw(self,color):
pygame.draw.rect(screen,pygame.Color(color),self.rect)
# Generates the odd row platforms
for i in range(rows-1):
rng = 0
if i > 1 and rng % 2 == 0:
rng = 1
else:
rng = random.randint(0,cols-2)
for j in range(cols-1):
left = 105 + j * (width *2)
top = i * (height *2)
if i % 2 != 0 and j == rng:
platform = Platform(left,top,width,height)
platforms.append(platform)
seed.append(j)
seed.append(seed[1])
#Generates the even row platforms based on the index of the odd row platforms
for l in range(rows):
for m in range(cols):
left = m * (width *2)
top = l * (height * 2)
if l % 2 == 0:
if seed[0] - seed[1] < 0 and m == seed[int(l/2)]:
platform_alt = Platform(left,top,width,height)
platforms_alt.append(platform_alt)
if seed[0] - seed[1] >= 0 and m == seed[int(l/2)]+1 or random.randint(0,100) <= 5 and (m == seed[int(l/2)] or m > seed[int(l/2)]):
platform_alt = Platform(left,top,width,height)
platforms_alt.append(platform_alt)
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_SPACE:
pass
# Odd row platforms painted red
for p in range(platforms.__len__()):
platforms[p].draw("red")
# Even row platforms painted blue
for q in range(platforms_alt.__len__()):
platforms_alt[q].draw("blue")
pygame.display.flip()
```
[Result of the code above](https://i.stack.imgur.com/W5aaL.png)
I've tried adding a condition that checked if a random number got to a specific value, and when it did, it would spawn an additional platform, however, that often resulted in the platform being isolated from all the other platforms, and generating an additional red platform broke the spawning of the blue platforms. |

It looks like you may be referring to a compile-time error. However, the `On Error` statement only handles a run-time error. So you should manually compile your code before trying to run it. This way you'll avoid a compile-time error when running it.
First, make sure that you have the following statement at the very top of your module before any procedures. This will force you to declare all variables. So, if you try to use an undeclared variable, you'll get a compile-time error.
Option Explicit
Then compile your code, and fix any errors that pop-up. Once any errors are fixed and your workbook is saved, any errors that pop-up will occur a run-time, which your `On Error` statement will catch.

***EDIT 4***
Ok, I hope this additional info seals it.
Firefox DOES bubble the synthetic CLICK that I generate on SPACEBAR / ENTER, but it DOES NOT bubble the mouse CLICK.
CHROME and EDGE work as expected. (both events bubble)
All Browsers bubble INPUT events for both mouse and synthetic clicks.
Both events are COMPOSED, CANCELLABLE, and BUBBLE.
The only difference I have seen is the synthetic CLICK event has had its TARGET set to ABC-TOGGLE#myToggle whereas the TARGET for the mouse CLICK is still input checkbox.
Note: I do understand that SPACEBAR is normally a first class CLICK event for checkboxes but I have stopPropagation() for uniformity with CR.
Why won't the mouse CLICKs traverse the DOMs?
***END EDIT 4***
**EDIT 3**
Ok, I'm an idiot! Never knew spacebar *is* an intrinsic click :-(
**END EDIT 3**
**EDIT 2**
More info: Chrome triggers both a Click and an Input event in that order. Firefox agrees with spacebar/synthetic event but won't surface a Click to the light DOM when the mouse is clicked.
[This][1] now works for FireFox and Chrome both TickBox and Toggle. But the SpaceBar CarrriageReturn functionality does not work. Still on it.
**END EDIT 2**
**EDIT 1**
Firefox does in fact bubble an event through to the light DOM but it is an INPUT event; not a CLICK event. Why?
**END EDIT 1**
The documentations says events triggered on elements in the Shadow DOM that make up a Web Component should pass from shadow to light DOM with the target, currentTarget, originalTarget et al coalesced into the Web-Component tagName, id, and so on.
This is not happening with FireFox in this [exaple][1]
in test_toggle.html I wish to be notified of a "click" event on my "disTick" tickbox so that I can disable the Toggle: -
document.getElementById("disTick").addEventListener("click", (e) => {
if (e.target.checked)
myToggle.disabled=true;
else
myToggle.disabled=false;
});
document.body.addEventListener("change", (e) => {console.log("****"+e.target.tagName);});
It gets called on Chrome, Edge, Opera, but not FireFox.
(I have tried to trap click, input, and chang events on BODY but nothing bubbles.)
Curiously enough, my synthetic event does bubble up (from toggle.js)
this.#toggle.addEventListener('keyup', (e) => {
if (e.altKey || e.ctrlKey || e.isComposing || e.metaKey || e.shiftKey)
return;
if (e.keyCode == 32 || e.keyCode == 13)
{
console.log("key = " + e.keyCode);
e.preventDefault();
this.#toggle.click();
}
});
What am I missing/ Why isn't the original click bubbling through light DOM on FireFox?

I am trying to cache some private custom rest endpoints using WP Rest Cache and whenever i try it makes them public? Not sure if anyone has come across this but i need it to remain private in the cache to authenticated users.

I'm using the following IIS Rewrite Rule to block as many bots as possible.
<rule name="BotBlock" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{HTTP_USER_AGENT}" pattern="^$|bot|crawl|spider" />
</conditions>
<action type="CustomResponse" statusCode="403" statusReason="Forbidden" statusDescription="Forbidden" />
</rule>
This rule blocks all requests with an empty User-Agent string or a User-Agent string that contains `bot`, `crawl` and `spider`. This works great but it also blocks `googlebot`, which I do not want.
So how do I exclude the `googlebot` string from the above pattern so it does hit the site.
I've tried
`^$|!googlebot|bot|crawl|spider`
`^$|(?!googlebot)|bot|crawl|spider`
`^(?!googlebot)$|bot|crawl|spider`
`^$|(!googlebot)|bot|crawl|spider`
But they either block all User-Agents or still do not allow googlebot. Who has a solution and knows a bit about regex?
**So thanks to The fourth bird the solution becomes:**
<add input="{HTTP_USER_AGENT}" pattern="^$|\b(?!.*googlebot.*\b)\w*(?:bot|crawl|spider)\w*" /> |

same in json file: analyzeDocResponse.json too but it has all (LINES, WORDS, LAYOUT_TITLE, and all layout related data), i think textract does all kind of block types in sequence.
for debugging purpose, i am using below code to print entire dictionary of block.
and also block type followed by its corresponding text.
if interested in pdf file: its SmPC of Drugs: [SmPC file](https://www.nafdac.gov.ng/wp-content/uploads/Files/SMPC/Covid19/Pfizer-BioNTech-SmPC-For-Covid-19-Vaccine.pdf)
code 1: printing each block in json format.
```
def start_textract_job(bucket, document):
response = textract.start_document_analysis(
DocumentLocation={
'S3Object': {
'Bucket': bucket,
'Name': document
}
},
FeatureTypes=["LAYOUT"] # You can adjust the FeatureTypes based on your needs
)
return response['JobId']
def print_blocks(job_id):
next_token = None
while True:
if next_token:
response = textract.get_document_analysis(JobId=job_id, NextToken=next_token)
else:
response = textract.get_document_analysis(JobId=job_id)
for block in response.get('Blocks', []):
print(json.dumps(block, indent=4))
next_token = response.get('NextToken', None)
if not next_token:
break
```
it is printing similiar info as per UI Demo, block type LINES, WORDS, LAYOUT_
but if i try to print text for each block type using below code, it fails to print for LAYOUT_ related , not sure why, am i missing anything?
code 2: to print block type followed by its content.
```
def start_textract_job is same as above, LAYOUT.
def print_blocks(job_id):
next_token = None
while True:
if next_token:
response = textract.get_document_analysis(JobId=job_id, NextToken=next_token)
else:
response = textract.get_document_analysis(JobId=job_id)
for block in response.get('Blocks', []):
print(f"{block['BlockType']}: {block.get('Text', '')}")
next_token = response.get('NextToken', None)
if not next_token:
break
```
I can see values for block type LINES, WORDS
but coming empty for LAYOUT as below, i think, it is identifying in block types but not its values.
LAYOUT_TITLE:
LAYOUT_FIGURE:
LAYOUT_TEXT:
LAYOUT_SECTION_HEADER:
LAYOUT_TEXT:
LAYOUT_SECTION_HEADER:

any help is highly appreicated, went thru doc and few other StackOverflow questions but couldnt find any help.
New to Tetract, sorry for noob Q?, if it is :)

Any time you invoke `get()` on a document reference, you will be billed 1 read if the program was able to reach the Firestore backend. The document data behind a reference is not cached after a write: it will be read again for each call to `get()`. |

I don't know if there's any way to detect it via the properties Python exhibits. But you can simply query to see if it's a version that is known to implement the PEP.
```Python
def has_pep528():
try:
import platform
import sys
if platform.python_implementation() == 'CPython' and tuple(sys.version_info) >= (3, 6):
return True
except:
pass
return False
```
You can add additional `if` statements as other implementations become known. |
Solution that works on start of 2024 with latest available Flutter + lib versions:
1.generic class (paging object in our case)
import 'package:json_annotation/json_annotation.dart';
part 'page_dto.g.dart';
@JsonSerializable(explicitToJson: true, genericArgumentFactories: true)
class PageDto<T> {
List<T> content;
int totalPages;
int totalElements;
int number;
int numberOfElements;
bool last;
bool first;
bool empty;
PageDto(
{required this.content,
required this.totalPages,
required this.totalElements,
required this.number,
required this.numberOfElements,
required this.last,
required this.first,
required this.empty});
factory PageDto.fromJson(Map<String, dynamic> json, T Function(Object? json) fromJsonT) =>
_$PageDtoFromJson<T>(json, fromJsonT);
Map<String, dynamic> toJson(Object Function(T) toJsonT) => _$PageDtoToJson<T>(this, toJsonT);
}
2.class that goes as generic in paging:
@JsonSerializable()
class WalletAccountRecord {
String id;
String accountId;
RecordAmount amount;
String date;
OperationType operationType;
String? category;
String? note;
List<String>? labels;
TransferDetails? transferDetails;
WalletAccountRecord(this.id, this.accountId, this.amount, this.date, this.operationType, this.category, this.note,
this.labels, this.transferDetails);
static WalletAccountRecord fromJsonModel(Object? json) => WalletAccountRecord.fromJson(json as Map<String,dynamic>);
factory WalletAccountRecord.fromJson(Map<String, dynamic> json) => _$WalletAccountRecordFromJson(json);
Map<String, dynamic> toJson() => _$WalletAccountRecordToJson(this);
}
3.example of usage in service:
Future<PageDto<WalletAccountRecord>> walletRecords(String walletId) async {
var url = '/wallets/$walletId/records';
var response = await get(url);
if (response.statusCode != 200) {
throw Exception('Request failed. Status: ${response.statusCode}');
}
debugPrint('Wallet json: ${response.body}');
dynamic data = json.decode(response.bodyString!);
return PageDto<WalletAccountRecord>.fromJson(data, WalletAccountRecord.fromJsonModel);

I am reading Mastering STM32 by Carmine Noviello and got to the chapter where I am about to work on the hello-nucelo project. I followed everything to the letter and still got the following error (see attachment):

As I am using an old mac that doesn't have 'system settings' and I don't have any external speakers, I will provide what works on my system to choose an alert sound, from Sound's Sound Effects. You should be able to map it to your setup and the output.
```
tell application "System Preferences"
activate
set ankor to anchor "effects" of pane id "com.apple.preference.sound" of application "System Preferences"
reveal ankor
end tell
tell application "System Events"
tell process "System Preferences"
set spk to "Glass" -- desired alert sound
-- collect the higher level ui elements in a single variable
set t1 to table 1 of scroll area 1 of tab group 1 of window "Sound"
-- list of table elements to select sound from
set rowRef to rows of t1
-- cycle through list of rows and compare each row's `value of text field 1`
repeat with ear in rowRef
if value of text field 1 of ear is equal to spk then
set matchingItem to contents of ear -- get row number of matching value
exit repeat
end if
end repeat
select matchingItem
--> row 6 of table 1 of scroll area 1 of tab group 1 of window "Sound" of application process "System Preferences" of application "System Events"
end tell
end tell
```
Now you have the result you need to create a more focused script:
```
tell application "System Preferences"
activate
set ankor to anchor "effects" of pane id "com.apple.preference.sound" of application "System Preferences"
reveal ankor
end tell
tell application "System Events"
tell process "System Preferences"
set glassAlert to row 6 of table 1 of scroll area 1 of tab group 1 of window "Sound" of application process "System Preferences" of application "System Events"
select glassAlert
end tell
end tell
```
If you find that the syntax differs from a more modern OS version, let me know. |

I've figured out the issue, and it wasn't an issue with the spec in question, although the behaviour was unexpected.
The underlying data that the page under tests relies on was not present. That's because in other specs I tested the same Stripe form-filling functionality and the assertions made in those tests **made the application wait until they were true**. In this test, however, the page was redirected with `visit subscription_path` before the result from the Stripe API were saved, thus causing an error.
The error raised in the test threw me off because it led me to believe that there was a dialogue box open that should not have been, whereas the actual issue was that **no dialogue box was open even though it was expecting one to be**. The cancel button was not present on the page because the subscription page was showing empty.
The test now looks like:
```ruby
RSpec.describe 'CancelSubscriptions', js: true do
it 'cancels an active subscription' do
email = sign_up_and_subscribe
expect(page).to have_current_path('/subscription/success', ignore_query: true) # making sure the Stripe return_url was hit and so the data is saved in my DB
click_on 'dropdown-toggle'
click_on 'Subscription'
expect(page).to have_content 'Your subscription'
accept_confirm do
click_button 'Cancel'
end
expect(page).to have_content 'We are cancelling your subscription.'
subscription = User.find_by(email:).current_subscription
expect(subscription.cancelled?).to be(true)
end
end
```
Takeaway: make sure the page is rendered as expected before making assertions on accepting confirmation or prompt dialogue boxes with Capybara/Selenium. Not doing can cause unexpected errors. |
I host two WordPress sites on a Windows 2019 Server, IIS 10, PHP 8.2 with FastCGI.
The two sites use exactly the same themes and plugins, in same versions.
One site works fine and the other generates 500 error on FastCGI with PHP 8.2, even when I deactivate all themes and plugins and use the default WordPress 2024 theme.
But it works fine if I swicth the FastCGI to use PHP 7.4.
When set with PHP 8.2:
I have enabled PHP error log: only deprecation level errors, and on both sites.
I have enabled WordPress debug log: only deprecation level errors, and on both sites.
I have enables Failed Trace Request log on IIS, I get this but I can't find any valuable information inside.

I got some problems with how i have to start writing the code. The problem is how i write fortran code to input the data of river section coordinates like using 'READ' as the command to input many coordinates in every sections with different shape. Maybe you guys can help me with that problems?.
i've tried writing the codes, but it doesnt work. I was expecting that the program work with just input the coordinate in many different river cross section while the code is compiling in fortran. |

net and to machine learning in general. I've been trying to load an object detection model on my local gpu but it tells me to load a vott json.
now I've downloaded the program and did all the steps excluding tagging all the hundreds of images that I have. Instead, I changed the asset state in the export setting to all images. Is that bad? because when I tried to load the exported vott json into visual studio it didn't do anything. it didn't even show me an error. |

I am working on an IoT application with over 15K lines of code using PlatformIO IDE, Espressif 6.2.0, and the Arduino framework.
I left the device running for about 28 hours, and everything was working fine until I encountered the following exception, which simply stated that the ISR WDT (Interrupt Service Routine Watchdog Timer) had timed out, which is understandable.
However, what happened next really confused me. The device attempted to reboot **97** times, and each attempt resulted in the same error. On the 98th attempt, the device got stuck in the reboot process and did not proceed further. It seemed as if the CPU was halted, but I do not know why or how exactly.
I have a single ISR in my program attached to a digital input. In that ISR, I only increment an integer variable by one and nothing else.
My question is, why might this have happened? Let's consider that my program has a major problem that occurs after 28 hours, but why doesn't the issue stop after rebooting?
Has anyone had a similar experience, and if so, what were the possible solutions?
Here is the start and end of the log for your reference:

I tried to make a game, but instead of drawing the enemy, I wanted to make it with .png. After updating the code, it stopped opening. please help me to solve that |
## Short Answer
In practice, the measured histogram discrepancy with a 4:2:2 jpg is ~1%, therefore one would expect about 16,609,443 colors—this is mainly due to factors other than YCbCr, such as the DCT compression.
# Longer Answer
The above value based on compressing using 4:2:2, and 100% quality. DCT artifacts are certainly part of the discrepancies. The measurement was using a histogram of the pure RGB image and compared to the 4:2:2 jpg, using DIFFERENCE transfer mode.
Some of the loss is due to the DCT algorithm, and some due to the spatial subsampling. That considered, the total colors would be no less than 16,579,244 to 16,642,998, but the difference is at worst effectively dithered. I.e. we are splitting hairs here.
Using Bruce Lindbloom's ["every possible color" image][1], an uncompressed RGB array of all possible colors, exported to a jpg at **100% quality** out of GIMP at **4:2:2**.
Then importing as a layer and setting it to difference transfer mode, to find any differences between the pure RGB and the 4:2:2 jpg.
For the following examples, I cropped to a small area of the full image.
## 100% Quality, 4:2:2
### The original:

#### The 4:2:2 jpeg laid on top, using difference mode:

#### A histogram of that result (16bpc was used):

#### Expanding that 1% range to full range, to show the nature of the differences:

## Discussion
In playing with this, including using 4:4:4 and 4:2:0 variants, it appears clear the main cause of the variations is the DCT compression, not so much the YCbCr. Perhaps it's useful to point out: we are never viewing YCbCr, we are always viewing RGB, thus the YCbCr is only the intermediate encoding for storage.
For every color stored in YCbCr it must be converted to a color in RGB. The only question then regards "round trips" in and out. I.e. for any given RGB color, mapped to a given YCbCr color, come back out to the exact same RGB color?
Here this is the difference with a jpeg that was exported five times consecutively:
[![RGB16Million422pass5DIFF][9]][9]
And expanded to show the bottom 1%:
[![RGB16Million422pass5DIFFexpanded][10]][10]
The vertical bars are due to the 4:2:2 subsampling. But otherwise, the discrepancy is essentially the same. This is consistent with the fact that after the first pass through DCT at 100% quality, subsequent passes at 100% quality have minimal effect.
## 50% Quality, 4:2:2
#### For reference, here is the difference using a 4:2:2 at 50% quality:
[![RGB16MillionCLIP422QUAL50DIFF][6]][6]
#### In this case the histogram of the difference indicates up to 25% discrepancy:

#### And expanded for detail:

## Conclusion
**We are always viewing RGB**.
There is no reason to think that the round trip RGB->YCbCr->RGB results in lost colors per se, assuming an appropriate reverse transform, and working in floating point (if working in int, some rounding may result in some round trip errors).
However, the addition of DCT compression and chroma subsampling certainly does add errors, the degree of which are largely dependent on the quality settings. The errors introduced due to DCT and subsampling are greater than those due purely to the color space transform.
