I am trying to decode data matrix qr codes using `pylibdmtx`. I have below image
[![enter image description here][1]][1]
[1]: https://i.stack.imgur.com/l4VRO.png
and using the below code:
import cv2
from pylibdmtx import pylibdmtx
import time
import os
image = cv2.imread('file1.png', cv2.IMREAD_UNCHANGED);
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
ret, thresh = cv2.threshold(gray, 0, 255, cv2.THRESH_BINARY | cv2.THRESH_OTSU)
t1 = time.time()
msg = pylibdmtx.decode(thresh)
print(msg)
if msg:
print(msg[0].data.decode('utf-8'))
t2 = time.time()
print(t2-t1)
It prints nothing. Is there anything I am missing in the code. I tried some [data matrix decoder online](https://www.dynamsoft.com/barcode-reader/barcode-types/datamatrix/), and they were able to decode it so I am sure image is correct but may be something is wrong in the code. Can anyone please help me out. Thanks |

I'm trying to build a table set in the form of a P&L in Looker studio. To build a table inside Looker you need to use the Pivot form, and it's not meeting my requirements (ex. I want a line 5 to be the sum of line 1, 2, 3, 4, then I want line 7 to be the difference between line 5 and 6...). So, how can I do to have this flexibility avoiding the only option of a pivot table in looker studio?
Thnx for the help
I tried to add a table on Looker studio but it's impossible to customize meeting my requirements |

The mistake is the result set from that query has _two columns_.
Otherwise, this dataset is a poor choice for demonstrating the JOIN types, because there are no values that are unique to A and B, such that the OUTER join types will always closely resemble the INNER join types. Really, the _only_ difference for the INNER join is excluding the `null` rows, because `null` is never equal to itself. You might also change the ordering of the sets for left vs right, but without an `ORDER BY` clause the order is meaningless and you are free to write the results in whatever order you want... and many databases will often silently rewrite RIGHT JOIN as the equivalent LEFT JOIN and give you the results as if you'd written it that way in the first place... ordering and all.
Finally, the correct listing of the join types is left, right, inner, cross, and full. You do not list "outer", because its already included as part of left right and full. More recently you might also include a sixth LATERAL type (APPLY in SQL Server). |
### Create some data
To illustrate the difference, let's construct some data:
```r
# Example dataset
(dat <- data.frame(
category = rep(c("A", "B"), each = 3),
value = c(1, 2, 3, 4, 5, 6)
))
# category value
# 1 A 1
# 2 A 2
# 3 A 3
# 4 B 4
# 5 B 5
# 6 B 6
```
And let's construct the barebones of a plot without a grouping variable (such as `color` or `fill` mapped to a plot aesthetic).
```r
g <- ggplot(dat, aes(x = category, y = value)) +
theme_minimal(base_size = 24)
```
### `position_dodge()`
If we try to apply `position_dodge()` to this data, it does not actually dodge the bars. They are stacked on top of each other, each one unit taller than the previous one on the y-axis:
```r
g +
geom_bar(
stat = "identity",
position = position_dodge(),
color = "black",
fill = NA
)
```
[![enter image description here][1]][1]
### `position_dodge2()`
Conversely, `position_dodge2()` understands the bars should appear side-by-side:
```r
g +
geom_bar(
stat = "identity",
position = position_dodge2(padding = 0),
color = "black",
fill = NA
)
```

[2]: https://i.stack.imgur.com/5LOP6.png
### Other differences
You might also noticed I provided `padding = 0`. That's because the `position_dodge2()` function takes two parameters, `padding` and `reverse`, that `position_dodge()` does not. These are set out in the [docs](https://ggplot2.tidyverse.org/reference/position_dodge.html). In those functions with a grouping variable, where you can use either, you need to set `position_dodge2(padding = 0)` to get identical output to `position_dodge()`. |

I'm new to nodejs and express-session. As far as i know, when saveUninitialized is set to FALSE, the uninitialized session cookie will not be saved into sessionStore (mongodb in my case). Here is my session configs
session: {

store: initializes.sessionStore,
resave: true,
**saveUninitialized: false**,

expires: 24 * 60 * 60 * 1000 * 7, // seven days\
httpOnly: true
}
}
In my database, the [sessions] collection is empty. I also delete all browser cookie. But everytime I make a request, there will be a session document in my collection.

I'm updating my Spring Boot application from Java 11 to Java 17, and Spring Boot `2.7.18` to `3.2.4`, and running the tests I'm getting an error.
So, I have a entity called `WorkloadDAO` like this:
```
@Entity
@Table(name = "workloads")
@IdClass(WorkloadId.class)
public class WorkloadDAO {
@Id
@NonNull()
private String id;
@Id
@Column(name = "created_at", insertable = false, updatable = false, columnDefinition = "TIMESTAMP")
private LocalDateTime createdAt;
// more attributes
@PrePersist
protected void onCreate() {
createdAt = LocalDateTime.now();
}
```
The `createdAt` attribute will always be received with null value, and it will be set by the `onCreate()` method annotated with `@PrePersist` before save the instance in the database.
As you can see in the annotation `@IdClass(WorkloadId.class)`, I'm setting `WorkloadId` as the id of this class. The `WorkloadId` class is like this:
```
public class WorkloadId implements Serializable {
private String id;
private LocalDateTime createdAt;
}
```
So far, so good until the test.
For example, I'm running this test:
```
@Test
void testSaveWorkload() {
String id = "someid";
WorkloadDAO dao = WorkloadDAO.builder()
.id(id)
.build();
WorkloadDAO response = repository.saveAndFlush(dao);
assertThat(repository.findById(WorkloadId.builder()
.id(id)
.createdAt(response.getCreatedAt())
.build()))
.get()
.extracting("createdAt").isNotNull();
}
```
Before updating Java and Spring Boot, this test was running successfully. But now, I'm getting the following error:
```
org.springframework.orm.jpa.JpaSystemException: identifier of an instance of com.adevinta.delivery.workloadapi.data.WorkloadDAO was altered from WorkloadId(id=someid, createdAt=2024-03-28T12:26:34.355098) to WorkloadId(id=someid, createdAt=null)
```
Can you help me to understand why I'm getting this?
Thanks!
What I expect to happen is the test works, without setting the field `createdAt` beforehand. |

I spent hours on this problem. I wanted to access the selected categories of my page in Typo3 Fluid, but there is no default way to do that. |
Typo3 Fluid: How to get selected page categories in fluid |
|typo3|typoscript|fluid| |
There **is** no default way of doing this. You need to query the database and join tables yourself. Thanks for nothing Typo3 – nobody could have expected, that developers would actually want to access the selected categories in their templates. (╯°□°）╯︵ ┻━┻
In the setup Typoscript in the Fluidtemplate, add a DatabaseQueryProcessor:
```typoscript
page = PAGE
page {
typeNum = 0
(...)
10 = FLUIDTEMPLATE
10 {
(...)
dataProcessing {
(...)
30 = TYPO3\CMS\Frontend\DataProcessing\DatabaseQueryProcessor
30 {
table = sys_category
selectFields = sys_category.*
pidInList = root,-1
recursive = 99
join = sys_category_record_mm ON (sys_category_record_mm.uid_local=sys_category.uid)
where = sys_category_record_mm.tablenames='pages' AND sys_category_record_mm.uid_foreign = ###pageuid###
orderBy = sorting
markers.pageuid.field = uid
as = pageCategories
}
}
}
}
```
This snippet creates a variable called `pageCategories`, which is an array of all selected categories for the current page. You can the access the title e. g. by `pageCategories.0.data.title` or loop over it in fluid:
```html
<f:for each='{pageCategories}' as='category' iteration='inter'>
<span class='category-tag'>{category.data.title}</span>
</f:for>
```
To be honest, I don’t understand the query syntax myself, but this is a working solution. There were just a few google results for this problem, and they either didn't work in my case, of where just never answered, so I wanted to share my solution.
Credits go to [t3brightside][1] who maintains the [pagelist][2] extension from which this code snippet was ~~inspired~~ (stolen).

I've tried making sure there's no white space and i've checked header.php, etc. i've tried using it with the "init" hook and also without it.

My program has a main while loop as the main logic, with an inner while loop for running the logic of the "command function". When inside the inner while loop, I want `EOF` (Ctrl + D) to exit from the inner while loop only and continue with the outer loop (to listen to more commands). However, its exiting from both the inner "command" loop and outer main while loop.
```java
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class Main {
public static void main(String[] args) {
String line;
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
try {
while ((line = reader.readLine()) != null) {
if (line.compareTo("echo") == 0) {
while ((line = reader.readLine()) != null)
System.out.println("echo: " + line);
// Ctrl+D (EOF) will exit loop
System.out.println("Stop echo-ing");
}
else System.out.println("Cmd not recognized");
// No EOF given, should not exit this loop
}
System.out.println("Exit main loop");
} catch (IOException e) {
System.err.println(e.getMessage());
}
}
}
```
To replicate problem:
1. Copy and paste code, and run it
2. Type `echo` to enter into inner while loop
3. Press `Ctrl` + `D` to provide `EOF` to standard input
The following is printed:
```shell
^D
Stop echo-ing
Exit main loop
```
"Exit main loop" is printed unexpectedly.
How can I exit only the inner while loop when `Ctrl` + `D` is pressed? |

I have an antd table in my project
version of antd : 4.25.15
react: "^16.8.6"
It looks like this:
```
<Table
dataSource={data}
columns={columnsForRender}
expandable={expandable}
/>
```
expandable props:
```
const expandable = {
expandIcon: ({ expanded, onExpand, record }) => {
if (!record.children) {
return null;
}
return expanded ? (
<MinusOutlined className='ant-table-row-expand-icon' onClick={e => onExpand(record, e)} />
) : (
<PlusOutlined className='ant-table-row-expand-icon' onClick={e => onExpand(record, e)} />
);
},
};
```
But this button doesn't look quite standard.
I want to use the standard button that is in the Table
example:
1st photo - my button[](https://i.stack.imgur.com/HfrB9.png)
2nd photo - standard antd button [](https://i.stack.imgur.com/Qh38O.png)
And i cant use this expandedRowRender and rowExpandable because this way create a new column
I try to use diffren classes, but a cant use expand and collapsed classes

I subscribe to several nodes at the same time, so that I receive a notification only when the values change. I have to save the data to a csv file and I write rows with the timestamp + all the values of the nodes. I implemented asyncio.Queue to handle the simultaneous writing but still if I receive more than one notification at the same time, the file gets updated with the first notification but not the other ones which are lost.
Here the output:
```
sv_writer_task started
Queue list:
<Queue maxsize=0>
Datachange notification received.

Dequeue value: 19.731399536132812
val name: TEMP
Prefix UC1 is no match for node: Unit_SB.UC3.TEMP.TEMP_v. Skipping.
Prefix UC2 is no match for node: Unit_SB.UC3.TEMP.TEMP_v. Skipping.

Prefix UC2 is no match for node: Unit_SB.UC3.HUMI.HUMI_v. Skipping.
csv file: UC3.csv
Updating existing row
Data written to file UC3.csv succesfully
```
In the csv file one can see in last line that only the TEMP value, which arrived first, was changed, but not the HUMI one:
```
Timestamp,OUT_G,OUT_U,HUMI,TEMP
29032024 14:08:42,True,True,47.38769912719727,15.043899536132812

here the code so far. Since I'm subscribing to several subsystem and each of them has it's own data file, I'm checking to which file to write:

I created my custom context menu using UIView. Im trying to change the corner radius when the context menu is active, but I have no idea how. I tried masks, layer whatsoever, but nothing worked. The provided current code is not rounding the corners.

The registry key of origin and the comparison operand imply that you're dealing with _version numbers_.
To meaningfully compare version numbers based on their _string representations_, cast them to `[version]`:
```
[version] $soft.DisplayVersion -lt [version] '124.0'
```
Note:
* For brevity, you could omit the RHS `[version]` cast, because the LHS cast would implicitly coerce the RHS to `[version]` too. However, using it on both sides can help conceptual clarity.
* For a [`[version]`](https://learn.microsoft.com/en-US/dotnet/api/System.Version) cast to succeed, the input string must have _at least 2_ components (e.g. `[version] '124.0'` and _at most 4_ (e.g, `[version] '124.0.1.2'`), and each component must be a positive decimal integer (including `0`).
* `[version]` is _not_ capable of parsing [_semantic_ version numbers](https://semver.org/), however, which are limited to _3 components_ and may contain non-numeric suffixes (e.g., `7.5.0-preview.2`).
* Use [`[semver]`](https://learn.microsoft.com/en-US/dotnet/api/System.Management.Automation.SemanticVersion) to parse semantic versions; however, that type is available in [_PowerShell (Core) 7_](https://github.com/PowerShell/PowerShell/blob/master/README.md) only.
* Unlike with `[version]`, a _single_ component is sufficient in the input string of a `[semver]` cast; e.g.,
`[semver] '124'` works to create version `124.0.0`. |
Long story short, PEBCAK - sort of. But I will leave this here in case someone else runs into a similar problem.
What I started out with was something like this - given that I was only expecting plain text data:
```
let data = "";
request.on("data", chunk => {
data += chunk.toString();
});
request.on("end", chunk => {
if (chunk) {
data += chunk.toString();
}
doSomethingWithTheBinaryData(data);
}
```
This, however, was pushing binary data into strings, causing the binary content to be modified, and `zlib` to no longer be able to decompress it. The proper way to receive binary data is:
A proper way to receive binary data from an http request is something like:
```
let data = [];
request.on("data", chunk => {
data.push(chunk);
});
request.on("end", chunk => {
if (chunk) {
data.push(chunk);
}
allData = Buffer.concat(data);
doSomethingWithTheBinaryData(allData);
}
```
Once I switched to this second form, both text and compressed data started to be received and processed correctly. |
I have a pretty simple class:
```swift
class TestClass {}
```
then I created an instance of this class:
```swift
let instance = TestClass()
```
After that I started my project (debug build) and ran command in Xcode console:
```
language swift refcount instance
```
and what I got was:
> refcount data: (strong = 3, unowned = 1, weak = 1)
I wonder why my instance has 3 strong references, 1 unowned and 1 weak, if in fact there is only 1 strong reference. |

I find myself in the position of needing to really use intrinsics for the first time as optimization for image conversion. I found this project here: [https://github.com/jabernet/YCbCr2RGB/blob/master/conversion.cpp ](https://github.com/jabernet/YCbCr2RGB/blob/master/conversion.cpp) and it almost works, but my output target needs to be in r8g8b8a8 while this is outputting in r8g8b8.

with the packAlpha lines added by me. I thought it would line things up properly, but what I ended up with was grayscale and had vertical while lines throughout. It's also flipped on both axes, but that was true before my changes, and can be solved by rotating the texture that pixels is given too later.
Edit: appended the calculation for the rgbX_Y variables to the top of the code block, per comment request. Also edited the numbers in the storing functions to reflect that I did in fact change those 3s to 4s |
Is anyone familiar with Proxmox API? Specificly on how to create VM, as part of my bootcamp I'm trying to develop a friendly UI (https://github.com/sbendarsky/Proxify.git) using next.js for proxmox and I cannot find a solution on how to do that.
I tried to search the web on how to do that but didn't find anything, I've only found solution on start/stop a VM but not on how to create one.
import axios from 'axios';
import https from 'https';
import { serverRuntimeConfig } from 'next.config';

const proxmox_token_id = serverRuntimeConfig.proxmox_token_id;
const proxmox_secret = serverRuntimeConfig.proxmox_secret;
const client = axios.create({
baseURL: `${proxmox_url}/api2/json`,
headers: {
Authorization: `PVEAPIToken=${proxmox_token_id}@pam=${proxmox_secret}`,
},
httpsAgent: new https.Agent({ rejectUnauthorized: false }),
});

};
const response = await client.post(`/nodes/${node}/qemu/`, vmConfig);
if (response.status === 200) {
res.json({ message: 'VM created successfully' });
} else {
res.json({ message: 'Failed to create VM' });
}
} catch (error) {

I Have a hql file which is being used in oozie hive action. I am running hive on spark engine by specifying the below in my hql file.
`set hive.execution.engine=spark;`
But the job is failing with error :
`java.lang.NoClassDefFoundError: org/antlr/runtime/tree/CommonTree`
`Caused by: java.lang.ClassNotFoundException: org.antlr.runtime.tree.CommonTree`
I researched about it and trying to solve this by setting `spark.executor.extraClassPath` & `spark.driver.extraClassPath`
I found this can be done by adding the entry in hive-site.xml . But I am trying to set this on run time by adding the below command in my hql file like below :
set spark.executor.extraClassPath=/abc/external_jars/antlr-runtime-4.7.jar;
set spark.driver.extraClassPath=/abc/external_jars/antlr-runtime-4.7.jar;
But how can I add multiple jar file like this or is this the correct way to set the Classpath in runtime via hive ?
Thanks
Tried to run hive query via oozie action by setting the engine as spark. But it is failing

I use segmented picker in iOS which contains few items. When user tap on not selected item this item becomes selected. Some of items can contain sub items. So when user tap on already selected type I need to show modal window with subitems for choosing one of them.
But taps on already selected items of segmented picker are not handling. I tried to use "long press" but it not works as well.
I would like to use native iOS design that's why I don't want use "buttons" instead segmented picker.
So the question is how I can handle tap on already selected item of segmented picker for showing sub items to choosing one of them? It can be "long press" or other alternative which will be intuitive for user.
```
import SwiftUI
struct CustomSegmentedPicker: View {
@State private var showModalSelectD: Bool = false
enum periods {
case A, B, C, D, All
}
@State var predefinedPeriod: periods = periods.All
@State var predefinedPeriodD: String = "D1"
var body: some View {
ZStack {
Color.clear
.sheet(isPresented: $showModalSelectD, content: {
List {
Picker("D", selection: $predefinedPeriodD) {
Text("D1").tag("D1")

}
.pickerStyle(.inline)
}
})

For future readers.
The IntelliJ plugin works fine for "trivial" cases.
I had a more complex case.
The online tool below did it correctly:
https://env.simplestep.ca/
The "text" of the site above is:
"Environment Variable Generator
for Spring Boot apps" (in case the website dies in the future)
Example of my complex case:
things:
combinations:
- nameOf: favoriteColor
valueOfValue: green
- nameOfName: favoritePlanet
valueOfValue: Mars
result from simplestep.ca
THINGS_COMBINATIONS_0_NAMEOF=favoriteColor
THINGS_COMBINATIONS_0_VALUEOFVALUE=green
THINGS_COMBINATIONS_1_NAMEOFNAME=favoritePlanet
THINGS_COMBINATIONS_1_VALUEOFVALUE=Mars
and this matches the spring documentation for "complex" types.
https://docs.spring.io/spring-boot/docs/current/reference/html/features.html#features.external-config.typesafe-configuration-properties.merging-complex-types
below is code snipplets from the docs.spring.io link above.

After inserting the 400000 records then I need to append some more records
If I use the above command then the existing records getting deleted here.

I wrote a code which exposes an C++ object to QML and I would like to check declared properties of the object with native JS things, but they does not work as it expected. I wrote `FizzBuzzDerived.properties` method and it works file as I would expect `Object.keys` work.
Result in case of calling the functions
```js
Object.keys(FizzBuzz); // -> []
Object.values(FizzBuzz); // -> []
JSON.stringify(FizzBuzz); // -> {}
FizzBuzz.properties(); // -> ["objectName", "fizz", "buzz", "foo", "bar"]

I'm creating a small program to create a batch of documents.
In the footer of each created document, I tried to reflect the serial number of the current page and the total number of pages in the document, that is, to provide a line like: “Page 1 of 3.”
However, it is not possible to correctly reflect the total number of pages in one document. The footer appears to display the total number of pages for the entire document package.
Here is part of my code:
```java
XWPFHeaderFooterPolicy headerFooterPolicy = firstDocument.getHeaderFooterPolicy();
if (headerFooterPolicy == null)
headerFooterPolicy = firstDocument.createHeaderFooterPolicy();
XWPFFooter footer = headerFooterPolicy.createFooter(XWPFHeaderFooterPolicy.DEFAULT);
XWPFParagraph parafooter = footer.createParagraph();
parafooter.setAlignment(ParagraphAlignment.RIGHT);
XWPFRun runfooter = parafooter.createRun();
runfooter.setText("First line");
runfooter.setFontFamily("Times New Roman");
XWPFParagraph parafooter1 = footer.createParagraph();
parafooter1.setAlignment(ParagraphAlignment.RIGHT);
XWPFRun runfooter1 = parafooter1.createRun();
runfooter1.setText("page no. ");
runfooter1.getCTR().addNewPgNum();
runfooter1=parafooter1.createRun();
runfooter1.setText(" of " + firstDocument.getBodyElements().size());
runfooter1.setFontFamily("Times New Roman");
firstDocument.write(new FileOutputStream(new File(fileString + "\\FirstFile.doc")));
firstDocument.close();
```
This is the result that appears in the footer:
```none
First line
page no. 1 of 41
```
I tried using different functions, but did not achieve a positive result.
|
The total number of document pages in the footer is not calculated correctly |
i am currently an apprentice an pretty new to delphi (Using Delphi 11 in RAD Studio) so i apologize if there is something obvious i'm missing. And i have to note i have to work with a 22 years old lagacy code with approx 600k lines so that could be an error factor as well :D
I was tasked to code a way to save all currently open Forms with their properties like size, position and window state and then restoring it after reopening the program. For that i decided to add in the FormCloseQuery in the Main Form a procedure which goes through all Forms and writes their data (if Visible true) in a .ini File. Works pretty great so far and this is how it looks like:
```
procedure SaveFormInformation();
var
i : Integer;
form : TForm;
iniFile : TIniFile;
begin
iniFile := TIniFile.Create(ExtractFilePath(Application.ExeName) + 'FormInfo.ini');
try
for i := 0 to Screen.FormCount - 1 do
begin
form := Screen.Forms[i];
if form.Visible then
begin
iniFile.WriteInteger(form.Name, 'Width', form.Width);
iniFile.WriteInteger(form.Name, 'Height', form.Height);
iniFile.WriteInteger(form.Name, 'Left', form.Left);
iniFile.WriteInteger(form.Name, 'Top', form.Top);
iniFile.WriteBool(form.Name, 'Visible', form.Visible);
iniFile.WriteBool(form.Name, 'IsMaximized', form.WindowState = wsMaximized)
end;
end;
finally
iniFile.Free;
end;
end;
```
And in the end the .ini File it looks like this:
```
[F_Main]
Width=719
Height=542
Left=600
Top=305
Visible=1
IsMaximized=0
[F_PartList]
Width=1126
Height=716
Left=71
Top=301
Visible=1
IsMaximized=0
```
Now to my problem... the restoring.
At first i tried the same way with Screen.FormCount and if Visible, read the .ini File and replace the values. That only worked partially because we have so many forms (masks), we decided to not initialize some of the forms in the beginning because perfomance.
Then i decided to turn things around and include a loop which reads the .ini and only changes whats written there. But before it changes the properties it looks if the form exists in the first place and creates it when not there. This part does not work the way i intent it to. The if statement - lookup works:
```
if Application.FindComponent(Sections[i]) as TForm = nil then
```
But the Application.CreateForm() doen't.
It seems like it cannot find the classes with their respective names alone. Thankfully we have a naming convention here so every TForm starts with F_ and every TFormClass with TF_ so it should theoretically be possible.
Here the procedure of RestoreForms():
```
procedure RestoreForms();
var
i : Integer;
iniFile : TIniFile;
form : TForm;
FormClass : TFormClass;
Sections : TStringList;
begin
iniFile := TIniFile.Create(ExtractFilePath(Application.ExeName) + 'FormInfo.ini');
Sections := TStringList.Create;
try
IniFile.ReadSections(Sections);
for i := 0 to Sections.Count -1 do
begin
{form := Application.FindComponent(Sections[i]) as TForm;
if not Assigned(form) then
begin
FormClass := TFormClass(GetClass('T' + Sections[i]));
Application.CreateForm(FormClass, form);
form.Free;
end;}
//Since not all Forms are initialized in the beginning this bit
//does it for you. If the Form is nil then create Form
if Application.FindComponent(Sections[i]) as TForm = nil then
begin
//FormClass := TFormClass(FindClass('T' + Sections[i]));
FormClass := TFormClass(GetClass('T' + Sections[i]));
form := Application.FindComponent(Sections[i]) as TForm;
Application.CreateForm(FormClass, form);
form.Free;
end;
//this puts the current read form of the ini File in a TForm Object
//to then change its properties
form := Application.FindComponent(Sections[i]) as TForm;
with form do
begin
form.Top := IniFile.ReadInteger(form.Name, 'Top', Top);
form.Left := IniFile.ReadInteger(form.Name, 'Left', Left);
form.Height := IniFile.ReadInteger(form.Name, 'Height', Height);
form.Width := IniFile.ReadInteger(form.Name, 'Width', Width);
if iniFile.ReadBool(form.Name, 'IsMaximized', WindowState = wsMaximized) then
form.WindowState := wsMaximized
else
form.WindowState := wsNormal;
form.Position := poDesigned;
if not (Sections[i] = 'F_Main') then
form.Visible := IniFile.ReadBool(form.Name, 'Visible', Visible);
end;
end;
finally
Sections.Free;
form.Free;
iniFile.Free;
end;
end;
```
Currently the code "opens" the program but no Form will be seen. Only Services in Taskmanager can free me of the process ^^"
I also thought about saving their Window States of all open Forms in their respective FormClass itself, but since we have like 1k Forms / Masks this task is close to impossible.
I hope you guys can give me some pointers or ideas since neither google nor stackoverflow nor AI could give me any answers as of now. |
Trying to calculate the area of a polygon recursively using the shoelace theorem and splitting it into triangles.
```
public static double calculatePolygonArea(ArrayList<Point> points) {
if (points.size() < 3) {
return 0;
}
if (points.size() == 3) {
return calculateTriangleArea(points.get(0), points.get(1), points.get(2));
}
return calculateTriangleArea(points.get(0), points.get(1), points.get(2)) +
calculatePolygonArea(new ArrayList<>(points.subList(1, points.size())));
}
private static double calculateTriangleArea(Point p1, Point p2, Point p3) {
return Math.abs((p1.getX() * p2.getY() + p2.getX() * p3.getY() + p3.getX() * p1.getY()
- p1.getY() * p2.getX() - p2.getY() * p3.getX() - p3.getY() * p1.getX()) / 2.0);
}
```
The code does not return the correct area and its always less than the actual area. |
I had the same issue. When there is an exception in any of the threads the library creates, the process hangs waiting for it to finish for hours. After running in one thread I found out the issue and fixed it. With the exception no longer occurring, the process hang is fixed. |
I built glib [link][1] with coverage.
`glib` uses the `meson` build system which requires the build to be generated in a separate directory.
I run `gcov` on each `gcno` file generated in order to get function coverage. I am interested in coverage broken down by function.
I ran into two problems:
1- For `gcno` files inside the build directory I get errors like
```
File '../glib/gcharset.c'
Lines executed:11.40% of 228
Creating 'gcharset.c.gcov'
Cannot open source file ../glib/gcharset.c
File '../glib/gstrfuncs.h'
Lines executed:100.00% of 1
Creating 'gstrfuncs.h.gcov'
Cannot open source file ../glib/gstrfuncs.h
```
I solved this by moving all the `gcno` and `gcda` files into a newly created directory in the root src directory of glib called `coverage_files`. This way this relative path for the c files would be work.
2- The second problem is the one I am currently stuck on. I get coverage for some functions exceeding 100%.
```
Function 'g_get_charset'
Lines executed:106.25% of 16
```
This is seen across many functions in different files and I can't figure out why or how this is even possible.
This is an example of the output for one `gcno` file.

I was able to find out why it was throwing the error, so thought that i would answer the question myself. The issue was `AuthRoute.tsx`, it should have passed as an element of the <Route />
example:
```
<Route
key={route.path}
path={route.path}
element={
<AuthRoute
path={route.path}
Component={route.component}
exact={route.exact}
requiredPermission={route.requiredPermission}
/>

I fixed it with

I dont know why you can't use

but it fixed it for me.

I have now a different approach.
After I clicked the Login Button I load the AppShell again with different visibility settings.
In my LoginViewModel
[RelayCommand(CanExecute = nameof(CanLogin))]
private async Task Login(object obj)
{
await Task.Run(() =>
{
if (Application.Current != null)
{
// Reload the AppShell
Application.Current.MainPage = new AppShell(new AppShellViewModel(true));
}
});
}
In my AppShellViewModel
public AppShellViewModel(bool login)
{
// Check if user made a login
if (login)
{
// Set Visibility Propertys
}

While learning and playing around with asyncio and aiohttp, faced this and was wondering if this was an occurance limited to VSC only?
This one keeps leaving residues from the previous loops.
```
while True:
loop.run_until_complete(get_data())
```
[](https://i.stack.imgur.com/OiuBe.png)
This runs without any residual tasks.
```
while True:
asyncio.run(get_data())
```
[](https://i.stack.imgur.com/Ju2RG.png)
```
session = aiohttp.ClientSession()
async def fetch(url, params=None):
async with semaphore:
async with session.get(url, params=params) as response:
return await response.json()
```
I tried moving the while loop inside the called method itself but still the same result. Also tried using semaphores with no better luck.
I was trying to manage multiple rest api call methods using aiohttp from within a single loop but with this happening, guess I am stuck with having to use asyncio.run separately for each api related method. So the only way right now is to keep closing and reopening separate loops.
Need I even to worry about the forever created tasks? I read that these are just residues from the previous loops and the impact load is nonexistent even with them constantly stacking up. Could this possibly be a VSC related issue? |
Figured it out by initializing the calendar correctly according to the version of the CDN I was using. I corrected to the latest version 6.
```
<script src='https://cdn.jsdelivr.net/npm/fullcalendar@6.1.11/index.global.min.js'></script>
var calendarEl = document.getElementById('calendar');
var calendar = new FullCalendar.Calendar(calendarEl, {
});
calendar.render();

If the warnings do not affect your code execution or performance, you can choose to ignore them.
import warnings
warnings.filterwarnings("ignore", category=FutureWarning) |
This should probably be considered an implementation detail of the `json` package, and also it might be a Python version thing. In any case, it becomes crucial with your implementation:
- The `dump()` function internally calls the `iterencode()` method on your encoder (see lines 169 and 176 [in the actual source code][1].
- Yet, the `dumps()` function internally calls `encode()` (see lines 231 and 238).
You can verify this by adjusting `encode()` and overriding `iterencode()` in your `JSONSerializer` like so:
```python
class JSONSerializer(json.JSONEncoder):
def encode(self, obj):
print("encode called")
... # Your previous code here
return super().encode(obj)
def iterencode(self, *args, **kwargs):
print("iterencode called")
return super().iterencode(*args, **kwargs)
```
… and you will see that only "iterencode called" will be printed with your test code, but not "encode called".
The other Stack Overflow question that you linked in your question seems to have the same issue by the way, at least when using a rather recent version of Python (I am currently on 3.11 for writing this) – see my [comment][2] to the corresponding answer.
I have two solutions:
1. *Either* use `dumps()` in your `Agent.memorize()` method, e.g. like so:
```python
def memorize(self):
with open("memory.json", "w") as w:
w.write(json.dumps(self.G, cls=JSONSerializer))
```
2. *Or* move your own implementation from `encode()` to `iterencode()`, e.g. like so:
```python
class JSONSerializer(json.JSONEncoder):
def iterencode(self, obj, *args, **kwargs):
if isinstance(obj, MutableMapping):
for key in list(obj.keys()):
if isinstance(key, tuple):
strkey = "%d:%d" % key
obj[strkey] = obj.pop(key)
yield from super().iterencode(obj, *args, **kwargs)
```
This 2nd solution seems to have the benefit that it works with both `dump()` and `dumps()` (see note below).
A note for completion: The `dumps()` function later seems to result in a call of `iterencode()`, as well (I did not track the source code so far as to see where exactly that happens, but from the printouts that I added it definitely happens). This has the following effects: (1) In the 1st proposed solution, as `encode()` is called first and we can make all adjustments for making our data JSON-serializable there, at this later point, calling `iterencode()` will not result in an error, any more. (2) In the 2nd proposed solution, as we reimplemented `iterencode()`, our data will be made JSON-serializable at this point.
**Update**: There is actually a third solution, thanks to the comment of @AbdulAzizBarkat: we can override the [`default()`][3] method. However, we have to make sure that we hand over an object type for serialization that is not handled by the regular encoder, or otherwise we will never reach the `default()` method with it. In the given code, we can for example pass the `Agent` instance itself to `dump()` or `dumps()`, rather than its dictionary field `G`. So we have to make two adjustments:
1. Adjust `memorize()` to pass `self`, rather than `self.G`, e.g. like so:
```python
def memorize(self):
with open("memory.json", "w") as w:
json.dump(self, w, cls=JSONSerializer)
```
2. Adjust `JSONSerializer.default()` to handle the `Agent` instance, e.g. like so (we won't need `encode()` and `iterencode()`, any more):
```python
class JSONSerializer(json.JSONEncoder):
def default(self, obj):
if isinstance(obj, Agent):
new_obj = {}
for key in obj.G.keys():
new_key = ("%d:%d" % key) if isinstance(key, tuple) else key
new_obj[new_key] = obj.G[key]
return new_obj # Return the adjusted dictionary
return super().default(obj)
```
Final side note: In the first two solutions, the keys of the original dictionary are altered. You probably don't want to have this as actually your instance should not change just because you dump a copy of it. So you might rather want to create a new dictionary with the altered keys and original values. I took care of this in the 3rd solution.

The grades table containes an id (primary key) student_id and quiz scores. A student_id can appear multiple times in this table.
The Subjects table is a simple list of subjects with a primary key.
The grades_subject table links the two with a subject id, grade id (The st_id links another table with student information). All three are a primary keys.
As you can see, a subject id can appear many times in this table as each student in the grades table can have multiple subjects. 20001 appears twice, once with subject id 1 and again with subject id 2 etc. Each subject id can also appear numerous times as numerous student_ids in the grades table can share one subject.
Im tyring to get all records in the grades table, grouped by subject id. So the result would be:
sbj_id 1...then all the students in that class with their respective grades.
sbj_id 2... and so one for all subjects.
I have tried various solutions from this site and many combinations of different types of joins, groupings and also used select distinct. I either get duplicate values, or the correct records in the grades table but only 2 subject_ids, or student grades getting repeated for each subject and other inaccurate results.I have also tried subqueries.
This is the closest I have gotten to the correct results (I understand I do not neet the group by grades_subject.sbj_id in the below query, its just to demonstrate that it works):
`SELECT grades.*, grades_subject.sbj_id
FROM grades
JOIN grades_subject ON grades.st_id = grades_subject.grd_id
where grades_subject.sbj_id = 49
group by grades_subject.sbj_id, grades_subject.grd_id`
It results in all the scores for all students in that class which demonstrates that with my current setup I should be able to get what I am looking for with the right query or grouping. When I remove the where clause, I should get each sbj_id, and then all students in that subject with their scores, then the next subject etc. However, it will retrieve the scores for the first student in the subject, then duplicate those results for all other students in that subject as shown below:
sbj_Id | grd_id | Q1 | Q2 | ....
'1', '20001', '50', '80',
'1', '20001', '50', '80',
'1', '20001', '50', '80',
'2', '20002', '80', '85',
'2', '20002', '80', '85',
'2', '20002', '80', '85',
Select Distint does not work, various join types do not work, selecting and grouping by ids in the grades table does not work including the primary id. Instead of listing everything I have tried that does not work...
How I can get my desired results with my current set up without changing my table setup as other tables and coding are built on it. The set up works well with all other types of queries that I need except when Im trying to get all student grades accross all subjects. If I must change the set up, please ellaborate on the simplest way.
Thank you.

I have Blazor page where I want to make a to-do list that updates either when a button is pressed, or when the user hits enter. I want "enter" and the button to do the same action (adding what I've typed into the box to my todo list. Right now 'enter' works, but I have to hit enter twice. I only want to have to hit it once. The button works as intended.
```
<input placeholder="Text Here" type="text" @onkeydown="@Enter" @bind="newTodo" />
<button @onclick="AddTodo">Add todo</button>
@code {
private string newTodo;
private IList<TodoItem> todos = new List<TodoItem>();
private void AddTodo()
{
// Todo: Add the todo
if (!string.IsNullOrWhiteSpace(newTodo))
{
todos.Add(new TodoItem { Title = newTodo });
newTodo = string.Empty;
}
}
public void Enter(KeyboardEventArgs e)
{
if (e.Key == "Enter")
{
// Todo: Add the todo
if (!string.IsNullOrWhiteSpace(newTodo))
{
todos.Add(new TodoItem { Title = newTodo });
newTodo = string.Empty;
}
}
}
}
<ul>
@foreach (var todo in todos)
{
<li>
<input type="checkbox" @bind="todo.IsDone" />
<input @bind="todo.Title" />
</li>
}
</ul>
```
I've tried removing @onkeydown="@Enter", but then obviously nothing fires but the button
and
if (e.Key == "Enter")
{
AddTodo()
}
I was hoping the later would skip some step that is requiring an extra input, but it made me double paste the code there.

Given a **host** compiler that supports it, you can use `std::bit_cast` in CUDA C++20 **device** code to initialize a `constexpr` variable. You just need to tell nvcc to make it possible by passing [`--expt-relaxed-constexpr`][1].

Maybe you can achieve this using ***dplyr*** and ***rowwise()*** operation to calculate the mean closeness for each row based on the friendship type specified. Here's how you can do it:
data2 <- data %>%
rowwise() %>%
mutate(mean_c = mean(c(friend1_closeness_friend2, friend1_closeness_friend3, friend2_closeness_friend3)[c(friendshipType_1, friendshipType_2, friendshipType_3) == "C"], na.rm = TRUE))
the mean_c column represents the mean closeness among friends categorized as type "C" for each participant. Hope it helps you! |

### Solution
The solution was really easy: uninstall and reinstall the `pg` (postgres) ruby gem for that rails app:
```sh
gem uninstall pg
```
then reinstall it
```sh
bundle install
```
now `rails server` works! |
I am not a pro at server administration, however, I can install the latest version of ImageMagick 7.1.1 and Imagick 3.7.0 in a server which is not controlled by Plesk.
But, I am using an AWS instance which is controlled by Plesk.
The current version of ImageMagick is 6.9 and Imagick 3.7.0 in my Plesk server.
But, I want to install the latest version of ImageMagick 7.1.1, as some of my website needs the new version.
But, I don't know how to do it in Plesk server.
How can purge/uninstall the current one and How can I install the New one and compile it with PHP?
Is there anyone who can provide me with the full step by step guide and what commands should I run via SSH?
I tried this instruction, but it just didn't work in Plesk Server.
```
sudo apt remove --purge imagemagick
```
```
sudo apt-get update && apt-get install -y -qq \
build-essential chrpath debhelper dh-exec dpkg-dev g++ ghostscript gsfonts libbz2-dev \

libwmf-dev libx11-dev libxext-dev libxml2-dev libxt-dev pkg-config pkg-kde-tools zlib1g-dev
```
```
git clone https://github.com/ImageMagick/ImageMagick.git ImageMagick-7.1.1
cd ImageMagick-7.1.1
./configure --with-rsvg --with-modules
make
sudo make install
sudo ldconfig /usr/local/lib
```
```
git clone https://github.com/Imagick/imagick
cd imagick
phpize && ./configure
make
make install
```
I have also added **extension=imagick.so** into my php.ini
