I'm currently working on integrating Microsoft Graph APIs into my Java application to retrieve license details for users in my Microsoft 365 tenant. I referred to the official Microsoft documentation [here](https://learn.microsoft.com/en-us/graph/api/user-list-licensedetails?view=graph-rest-1.0&tabs=java) to understand the usage of the Microsoft Graph Java SDK for this purpose. However, despite following the provided guidance, I'm encountering difficulties in implementing the solution within my Java codebase.
**Context:**
- I'm utilizing the Microsoft Graph Java SDK to interact with Microsoft 365 APIs.
- Specifically, I'm referring to the documentation for listing license details for a user [here](https://learn.microsoft.com/en-us/graph/api/user-list-licensedetails?view=graph-rest-1.0&tabs=java).
- My authentication setup and GraphServiceClient instantiation are already in place, following the documentation.
**Issue:** The code snippet provided in the documentation is as follows:
```java
// Code snippets are only available for the latest version. Current version is 6.x
GraphServiceClient graphClient = new GraphServiceClient(requestAdapter);
LicenseDetailsCollectionResponse result = graphClient.users().byUserId("{user-id}").licenseDetails().get();
```
I've attempted to integrate this code into my Java application. While I can successfully query the Microsoft Graph API using tools like Postman, I'm unable to replicate the functionality within my Java codebase.
**Expectation:** I'm seeking assistance in understanding and resolving the following:
1. How can I properly configure the `requestAdapter` required for initializing the `GraphServiceClient` instance in Java?
2. Are there any additional configurations or dependencies required to make the Microsoft Graph Java SDK work seamlessly within a Java application?
I appreciate any insights or guidance on how to resolve this issue and successfully retrieve license details for users using the Microsoft Graph Java SDK within my Java application. |

It's an array of pointers to C strings (or char arrays). Where each string in the array is in the first[] and each character is in a second [], and each string of chars is an array of characters typically terminated by a null character or a zero byte.
In main() the argc parameter specifies how many strings there are in the char *arcv[] array.
The operating system when calling into main will specify the number of parameters, the int argc value as well as the command line parameters provided to main() in the char *argv[] parameter.
The first argv parameter is typically the program name itself, and this is followed by any additional parameters specified on the command line.
So for instance if you did:
./program.bin parameter1 --option1
And the data in it would be dereferenced like this:
puts(argv[0]) // would be "./program.bin"
puts(argv[1]) // would be "parameter1"
puts(argv[2]) // would be "--option1"
and argc would be 3.
The way i'd think of this is as char **argv, in fact you can replace char *argv[] as char **argv.
And I would think of this in the layout `char *(argv[stringnum])` or `char (argv[stringnum])[letternum]` or just `char argv[stringnum][letternum]`
Now, the reason:
(char *argv)[]
doesn't work is, is because your declaration of the variable argv is embedded within some code to dereference it and the compiler is confused about whether it's a declaration or a function. In the error message it thinks it should be a declaration, but it doesn't understand the format. Instead use `char *argv[]` or `char **argv`

The issue with your regex is that you have `\d` and `\)` which appear in the regex as `d` and `)` (due to string parsing prior to the regex engine) the latter then causes an "unmatched closing parenthesis" error at the next `)`. You need to escape the `\` to ensure you get `\d` and `\)` into the regex i.e.:
```regex
'/(\\d+)(?![^(]*\\))'
```
Note the `.*` at the beginning of the regex is not necessary as you are not interested in those characters anyway.
Assuming you are using MySQL > 8.0.4, when the switch was made to the ICU engine, this will work fine, although it will give you a string ending with the last digits following a `/` but not inside brackets. You then just need to extract those digits, which you can do with another regex:
```
\\d+$
```
In SQL:
```sql
SELECT REGEXP_SUBSTR(REGEXP_SUBSTR(myStr, '/(\\d+)(?![^(]*\\))'), '\\d+$') FROM myTable;
```

I understand that a ternary conditional operator can be used to shorten the following:
if x > a:
y += 12
else:
y += 10
re-written as:
y += 12 if x > a else 10
Is there something to shorten a statement if it's just the if portion with no else?
i.e.:
if x > a:
y += 12
can be re-written as:
y += 12 if x > a else 0
But I'm curious if there is an operator that doesn't add an else condition to a simple if statement with no else block. |

I have an xarray.Dataset that looks like:
print(ds2)

Dimensions: (time: 46, latitude: 360, longitude: 720)
Coordinates:
* time (time) datetime64[ns] 1976-01-01 1977-01-01 ... 2021-01-01
* latitude (latitude) float64 89.75 89.25 88.75 ... -88.75 -89.25 -89.75
* longitude (longitude) float64 -179.8 -179.2 -178.8 ... 178.8 179.2 179.8
Data variables:
Glacier (time, latitude, longitude) float64 dask.array<chunksize=(1, 360, 720), meta=np.ndarray>
Uncertainty (time, latitude, longitude) float64 dask.array<chunksize=(1, 360, 720), meta=np.ndarray>
I also have a raster with similar dimensions:
print(np.shape(rgi_raster))
(1, 360, 720)
How do I add rgi_raster to the xarray.Dataset so that it has the same time,lat,lon coordinates at the Glacier and Uncertainty variable?
I tried:
ds2=ds2.assign(rgi_raster=rgi_raster)
But this gives:

I tried to build project via idea, gradle 8.5(7.5, 8.7) and gradle wrapper 8.5. I have to admit that the same project built via maven was compiled successfully.
The most voted solution didn't help. The gradle plugin portal is being redirected to jcenter repo even though it has been deprecated. Local build is still attempting to download libs from the jcenter.
My workaround was to disable jcenter repo and enforce using maven central or another maven repo for plugin resolution. Eventually I managed to fix it.
The final solution is pretty simple. Just needed to add mavenCentral to plugin management repository config:
settings.gradle
pluginManagement {
repositories {
mavenCentral()
}
}
rootProject.name = 'gradle-failed'

Basic Python Question: Shortening If Statements |
|python|if-statement|conditional-statements|conditional-operator| |
null |
You can use `printf` with the space and then a separate line feed. Also `putchar` is a thing. Furthermore you should keep stack 16 byte aligned and using the exit syscall is bad practice.
A possible solution:
extern printf
extern putchar
global main
section .data
format_specifier:
db '%X', 0x20, 0 ;format specifier for printf with trailing space
section .text
main:
push rbx ; rbx is callee-saved. Also aligns stack.
mov ebx, 15 ; 32 bits is enough
loop1: ;loop to decrement and print number in ebx
lea rdi, [rel format_specifier] ; use position independent code
mov esi, ebx
xor eax, eax ; 32 bit ops zero extend
call printf wrt ..plt ; PIC
dec ebx
jns loop1
mov edi, 10 ; LF
call putchar wrt ..plt
xor eax, eax ; exit code
pop rbx
ret
Caveat: this will print a space after the final `0`.
Or, you can avoid `printf` altogether:
extern putchar
global main
main:
push rbx ; rbx is callee-saved. Also aligns stack.
mov ebx, 'F'
loop1: ;loop to decrement and print char in ebx
mov edi, ebx
call putchar wrt ..plt ; PIC
dec ebx
cmp ebx, '0'
jb done
cmp ebx, 'A' - 1
jne space
mov ebx, '9'
space:
mov edi, ' '
call putchar wrt ..plt
jmp loop1
done:
mov edi, 10 ; LF
call putchar wrt ..plt
xor eax, eax ; exit code
pop rbx
ret

I am using the [Llama-2-7b-hf][1] model with the `model.generate` function from the transformers library (v4.38.2) and it's returning the outputs as a single tensor, instead of the dict I expected.

I am store ~1500 last events in Redis in soreted set.
When set is more than 1500 elements, which is better (least loaded) way to clear first events?
Im using redis:6.0.2
Several options come to mind:
1. Simplest is using something like CRON or some interval to clear it
2. Using some global count and increment it in every request to this table. And clear it when this count are more than 100
or is there another better way? |
To simplify the example, I consider a dataframe with 3 10-Q and 2 10-K entries for each of two values of *cik*. I'll filter for the 2 most recent 10-K rows and the most recent 10-Q row for each group defined by *cik*.
```python
import polars as pl

df = pl.DataFrame({
"cik": [0] * 5 + [1] * 5,
"form": (["10-Q"] * 2 + ["10-K"] * 3) * 2,
"period": [datetime.date(2021, 1, 1+day) for day in range(10)],

To filter the dataframe for each group defined by *cik*, we can simply use `pl.DataFrame.filter` together with `pl.Expr.over` (to define the groups) as follows.
```python
(

**Explanation.**
1. We sort the DataFrame in descending order by *date* for each group defined by *cik* and *form*.
2. We filter the dataframe for rows with *form* being 10-K and the row index being less than 2 (0 or 1 - **with your data, you'd filter rows with row index less than 10**) or *form* being 10-K and the row index being 0, i.e. the most recent entry. We use `pl.Expr.over` to do this filtering separately for each group defined *cik* and *form* (to ensure the index is being reset properly for each form). |
I understand that a ternary conditional operator can be used to shorten the following:
```
if x > a:
y += 12
else:
y += 10
```
re-written as:
```
y += 12 if x > a else 10
```
Is there something to shorten a statement if it's just the if portion with no else?
i.e.:
```
if x > a:
y += 12
```
can be re-written as:
```
y += 12 if x > a else 0
```
But I'm curious if there is an operator that doesn't add an else condition to a simple if statement with no else block Something similar to the idea of:
```
y += 12 if x > a
```
even though I know this is syntactically incorrect. |

I am trying to find the numbers that ends with 4 in a list of numbers. I tried the following code but getting an error message saying *TypeError: list indices must be integers or slices, not str*
```
x = [12, 44, 4, 1, 6, 343, 10, 34, 12, 94, 783, 330, 896, 1, 55]
x_str = list(map(str, x))
for ele in x_str:
if x_str[ele][-1] == "4":
print(ele)
```
I tried to modify the code by making ```x_str[ele][-1]``` an integer. But now I am getting another error message saying *TypeError: 'int' object is not iterable*
```
x = [12, 44, 4, 1, 6, 343, 10, 34, 12, 94, 783, 330, 896, 1, 55]
x_str = list(map(str, x))
for ele in x_str:
if int(x_str[ele][-1]) == 4:
print(ele)
```

This is my (untested) code to perform this operation on nested directories:
def latest(file: File): File =
if (file.isDirectory) {
latest(file.listFiles.maxByOption(_.lastModified).getOrElse(file))
} else {
file
}
This is tail recursive and will compile to a simple loop. |
I'm developing a web compiler in TypeScript and I've encountered a small, but still irritating issue:
I have a progress bar inside an iframe element which keeps rendering for a short amount of time.
I want that progress bar to be rendered only when there's a code bundling process.
Here's a piece of that TypeScript code:
codeCell.tsx(The CodeCell component)
```
const bundle = useTypedSelector((state) => state.bundles[cell.id]);
return(
<>
<Resizable direction="vertical">
<div className="h-100 d-flex flex-row position-relative">
<Resizable direction="horizontal">
<div className="position-relative w-100">
<CodeEditor
initialValue={cell.content}
onChange={handleEditorChange}/>
</div>
</Resizable>
<div className="progress-wrapper">
{!bundle || bundle.loading ? (
<div className="progress-cover">
<progress hidden={!bundle} max="100"/>
</div>
) : (
<Preview code={bundle.code} err={bundle.err} cell={cell}/>
)}
</div>
</div>
</Resizable>
</>
);
```
useTypedSelector.ts(useTypedSelector hook):
```
export const useTypedSelector:
TypedUseSelectorHook<RootState> = (selector) =>{
const result = useSelector(selector, shallowEqual);
return useMemo(() => result, [result]);
};
const shallowEqual = (a: any, b: any) =>{
if (a === undefined || b === undefined){
return false;
}
for(let key in a){
if(a[key] !== b[key]){
return false;
}
}
for(let key in b){
if(!(key in a)){
return false;
}
}
return true;
};
```
preview.tsx (Preview component):
```
interface PreviewProps{
code: string;
err: string;
cell: Cell;
}
const Preview: React.FC<PreviewProps> = ({ code, err, cell }) =>{
const iframe = useRef<any>();
useEffect(() =>{
iframe.current.srcdoc = html;
setTimeout(() =>{
iframe.current.contentWindow.postMessage(code, '*'); // Posts the result from the code bundling
}, 10);
}, [code]);
return(
<div className="preview-wrapper">
<iframe
title="code preview"
ref={iframe}
sandbox="allow-scripts"
srcDoc={html}/>
{err && (
<div className="preview-error">
{err}
</div>
)}
<div style={{ display: "none" }}>
<div className="action-bar">
<ActionBar id={cell.id}/>
</div>
</div>
</div>
);
}
export default Preview;
```
One of the approaches I tried is using a ternary operator inside the Preview component's props stating that if there's a code bundling process you'll see the progress bar (the same if there's a code error) and if not (there's no code at all), you'll see an empty string (meaning you'll see an empty iframe element). |

I receive a file from a third party. The file seems to contain both ANSI and UTF-8 encoded characters (not sure if my terminology is correct).
Changing the encoding in Notepad++ yields the following:
[![Notepad++ screenshot][1]][1]
[1]: https://i.stack.imgur.com/G0hcd.png
So when using ANSI encoding, Employee2 is incorrect.
And when using UTF-8 encoding, Employee1 is incorrect.
Is there a way in C# to set 2 encodings for a file?
Whichever encoding I set in C#, one of the two employees is incorrect:
string filetext = "";
filetext = File.ReadAllText(@"C:\TESTFILEx.txt", Encoding.GetEncoding("ISO-8859-1")); // Employee1 is correct, Employee2 is wrong
filetext = File.ReadAllText(@"C:\TESTFILEx.txt", Encoding.GetEncoding("Windows-1252")); // Employee1 is correct, Employee2 is wrong
filetext = File.ReadAllText(@"C:\TESTFILEx.txt", Encoding.UTF7); // Employee1 is correct, Employee2 is wrong
filetext = File.ReadAllText(@"C:\TESTFILEx.txt", Encoding.Default); // Employee1 is correct, Employee2 is wrong
filetext = File.ReadAllText(@"C:\TESTFILEx.txt", Encoding.UTF8); // Employee1 is wrong, Employee2 is correct
Has anyone else encountered this and found a solution?

The IsShuttingDown property is an internal static property of the Application class therefore you can access to value it with below code

Trying to put multiple arguments into a string in Bash is generally not a good idea. Sometimes the only way to make it work is to use `eval`, and that often just gives you more problems (some of which may be very unobvious). See [Why should eval be avoided in Bash, and what should I use instead?](https://stackoverflow.com/q/17529220/4154375).
In this case I'd avoid the problem by defining the (Bash) function like this:
function myFunc
{
codesign "${@:2}" "$1"
}
and calling it like this:
myFunc "/MyFolder/MyFile.dylib" -f -vvvv --strict --deep --timestamp -s "Developer ID Application: My Company Inc. (123456)" --options runtime
I.e. put the path of the file to be signed as the first argument and the arguments to `codesign` as the following, all separate, arguments. Any arguments that work with `codesign` itself are guaranteed to work when provided as arguments (2 and following) to `myFunc`.
Note that if the intention in using a function like this is to make it easy to use different sets of options with `codesign` for different files, then it is important to keep lists of options in arrays instead of strings. This code demonstrates how to use an array to build up the full list of options in stages before calling the function:
codesign_opts=( -f -vvvv --strict --deep --timestamp )
codesign_opts+=( -s "Developer ID Application: My Company Inc. (123456)" )
codesign_opts+=( --options runtime )
myFunc "/MyFolder/MyFile.dylib" "${codesign_opts[@]}"

I have an array like this:
$sports = array(
'Softball - Counties',
'Softball - Eastern',
'Softball - North Harbour',
'Softball - South',
'Softball - Western'
);
I would like to find the longest common prefix of the string. In this instance, it would be `'Softball - '`
I am thinking that I would follow this process
$i = 1;
// loop to the length of the first string
while ($i < strlen($sports[0]) {
// grab the left most part up to i in length
$match = substr($sports[0], 0, $i);
// loop through all the values in array, and compare if they match
foreach ($sports as $sport) {
if ($match != substr($sport, 0, $i) {
// didn't match, return the part that did match
return substr($sport, 0, $i-1);
}
} // foreach
// increase string length
$i++;
} // while
// if you got to here, then all of them must be identical
Questions
1. Is there a built-in function or a much simpler way of doing this?
2. For my 5 lines array that is probably fine, but **if I were to do several thousand lines arrays**, there would be a lot of overhead, so I would have to be move calculated with my starting values of `$i`, eg `$i` = halfway of string, if it fails, then `$i/2` until it works, then increment `$i` by 1 until we succeed. So that we are doing the least number of comparisons to get a result.
Is there a formula/algorithm out already out there for this kind of problem? |

The code setup is as follows:
- Module ui_theme.py defines a theme and variant selector.
- variant_selector has an on_change event handler.
- Module cards_page.py imports ui_theme.py
and has a handler on_variant_change.
Now, what I want to achieve that when ui_theme.on_change event is invoked then it should somehow call the cards_page.on_variant_change event.
Constraint: I definitely do not want to create a function to generate variant_selector. That makes the code-org bit messy. I also, can not post initialization, set the event handler.
My current solution is as follows:
- ui_theme.py
```
on_change_variant_callback = None
def on_change_variant_click(dbref, msg, to_ms):
print ("button clicked:", msg.value)
if on_change_variant_callback:
on_change_variant_callback(dbref, msg, to_ms)
pass
```
- in cards.py
```
import ui_theme
def on_variant_select():
pass
ui_theme.on_change_variant_callback = on_variant_select
```
Seems to me that there should be a better way -- probably this where dependency injection can help, although i don't understand that concept well enough.

`char *second = "test5";` initializes `second` to point to the first character of the array created by a string literal. About string literals, C 2018 6.4.5 7 says:
> … If the program attempts to modify such an array, the behavior is undefined.
Since your program attempts to modify the array when it calls `strcpy(second, first);`, the behavior of your program is not defined.
A common behavior of C implementations is to put the arrays of string literals in memory marked as read-only for the process, so attempting to modify such an array causes a memory access violation.
Compiler optimization may also cause other behaviors initially surprising to programmers as optimization may assume that no attempt to modify the array of a string literal occurs and hence may transform the program based on that assumption. |
Well I'm trying to enable my users to login with their gmail accounts like I saw in some sites on the top right of the browser windows as I show in the image.

As others mentioned before, in 2 steps:
1. Dex2jar
2. Pick up a decompiler
I will focus on step 2.
Take a look at this research paper : [The Strengths and Behavioral Quirks of Java Bytecode Decompilers][1]
Understand the strength and weaknesses of each decompiler.
1. [CFR][2]: Considered by many as the absolute best decompiler, its specificity is that it takes a lot a liberty in graph transformations to maximise the chance of good results, at the expense of original code ordering, and has a lot of technical settings. The last version has a line number mapping but no line number realignment.
2. [Procyon][3]: This one has the best chances to produce well structured code, adds final keywords everywhere it can, but often adds unexpected illegal casts. It has also a GUI project [Luyten][4].
3. [Fernflower][5]: It's the decompiler from the popular IDE Intellij Idea. It often decompiles right but code is sometimes not ideally structured and has very bad naming of exception variables var1..n.
4. [Vineflower][6]: It's a fork of fernflower which brings improvements and bug fixes, with a test suite borrowed to CFR.
5. [JD-GUI][7]: It's the GUI of the [JD-CORE][8] project. The new version of JD-CORE structures the code into a control flow graph and an abstract syntax tree. The previous version which was present until v1.4.2 of JD-GUI was another decompiler based on bytecode pattern matching like [JAD][9]. JD-CORE is focused on producing a recompilable output on many open source projects and also on getting line number realignment right for a debug-ready output.
6. [JADX][10]: This project looks actively maintained and promising, but for the time being, the results are not very solid.
The following GUI projects support several decompilers:
- [Recaf][11]: provides support for the following decompilers: CFR · FernFlower · Procyon
- [Bytecodeviewer][12]: A Java 8+ Jar & Android APK Reverse Engineering Suite (Editor, Debugger, decompilers like CFR, JD-GUI etc.)
- [JD-GUI-DUO][13] : this project uses forks of JD-CORE projects and revives the old algorithm in project named [jd-core-v0][14] and brings improvements and bug fixes in a fork of [jd-core v1][15]. Also supports CFR, Procyon, Vineflower & JADX.
Also Eclipse plugins are worth mentioning:
- [ECD][16] and this [fork][17]
- [JD-Eclipse][18] and this [fork][19]

Single backtick is working in the browser or anywhere else with the combination Shift + ^ but in VSCode I am unable to type a single backtick, I need to do this combination twice & get 2 backticks and the cursor jumps to the right of the second backtick then when I try to go back with the left arrow key I get a special symbol as in the image; FS in a red square, I think some other key combination must be in conflict with the backtick. I'm using a Macbook with Swiss keyboard layout.

I've tried defining cut_scene_manager within the Player class, but more problems keep occurring, usually with Player lacking attributes, or with CutSceneManager having 'unsupported opperand types'. Apologies if the problem is very obvious, I'm fairly new to Pygame and OOP, but this is a school project. Thank you! |

When attempting to SSH into a remote host, if you encounter an issue where the connection fails with an error message, it's possible that the host's key has changed since the last connection. One solution to resolve this issue is to remove the entry associated with the remote host from the `known_hosts` file.
Here are the steps to follow:
1. Locate the known_hosts file on your local machine. This file is typically located in the `.ssh` directory within your home directory.
1. Open the `known_hosts` file using a text editor.
1. Search for the entry corresponding to the remote host that you are trying to SSH into.
1. Delete the entire line containing the entry for the remote host.
1. Save the changes to the `known_hosts` file.
1. After removing the outdated entry from the known_hosts file, you should be able to SSH into the remote host without encountering any further issues. |
