I am relaying my ssh connection and I want to restrict the ability of the remote user to view my files so I set `umask = 047`. However, it seems to also affect the local user in some way as I can no longer `mkdir` as the local user using either
```
mkdir test
```
or
```
sudo mkdir test
```
both yield `Permission denied` error
However, I can
```
touch test
```
with no problem. I have checked that ownership of the current folder is the local user logged into wsl. |

Kind of new to user authorization. After a few researches, I have a general idea of access and refresh token design with JWT. However, I still have a few questions:
1, After user signs in, user gets access and refresh token. Eventually, when user sends certain request, say "reqA", access token expires. Then user needs to send request to auth server with refresh token to get new access token. Then send the reqA again? In short, at some point of time while we are logged in, we need to make three requests just to successfully obtain resources from reqA? If expires duration is fairly short, we are frequently making extra requests just to refresh this access token?
2, From question 1, knowing that access token is expired ONLY by failing a request seems clumsy. When and how should we refresh access token? Should we set up some scheduled interval to refresh access token, listen to some event to fresh, etc in frontend?
3, Or should we somehow check the iat and expiration attributes of the access token before sending any requests and refresh access token as needed (say only refresh within the last 1 minute before it expires).
Thanks |

I have set up a Kubernetes cluster with a single master node and three worker nodes running in VMs. Within this cluster, I deployed an nginx pod and created a LoadBalancer service using MetalLB to allocate an external IP address. The LoadBalancer service is exposing port 80, and when I SSH into the VM hosting the Kubernetes cluster and curl the external IP address, I receive the expected response from nginx.
However, when attempting to access the service from my local device using the same external IP address, I encounter a connection failure with the error message: "Failed to connect to <IP> port 80 after 348 ms: Couldn't connect to server."
I suspect the issue may lie in the IP address range specified in the IPAddressPool of MetalLB. Currently, I've assigned an external IP address within the range of my master node. How can I determine the appropriate value for the IP address range in MetalLB's IPAddressPool to enable access to the LoadBalancer service from devices outside the Kubernetes cluster?
Any guidance or suggestions would be greatly appreciated.

When using FLATTEN function in Snowflake, we use the values in the PATH column, to dynamically construct a SELECT clause to query the semi-structured (JSON) column in the data table.
We concatenate:
```
<variant_col>:<value_in_path_column>,
```
This means we assume the values in the PATH column are to be used with the Dot Notation (as described [here](https://docs.snowflake.com/en/user-guide/querying-semistructured#dot-notation))
We encountered a rare scenario, where the field key inside the variant column conatains a dot (.) in it, for example:
```
{
"0.text": "some_string_value",
"legal_name": "other_string_value"
}
```
In this case, after running the FLATTEN function, we get the following output:
| VARIANT_COL | SEQ | KEY | PATH | INDEX | VALUE
| -------- | -------- | -------- | -------- | -------- | -------- |
| { "0.text": "foo", "legal_name": "bar" } | 1 | 0.text | ['0.text'] | | "foo" |
| { "0.text": "foo", "legal_name": "bar" } | 1 | legal_name | legal_name | | "bar" |
We expect the value in the PATH column to be `"0.text"` instead of `['0.text']`
Is there a way to force it into a Dot Notation?
Thanks
Code to recreate the issue:
```
create temp table notation_issue
as select parse_json($${"0.text": "foo", "legal_name": "bar"}$$) as variant_col;
create temp table flatten_results as
select *
from notation_issue,
lateral flatten(variant_col, recursive=>True);
select 'select ' || listagg('variant_col:' || path, ',\n') || ' from notation_issue'
from flatten_results
;
/* This raises an error */
select variant_col:['0.text'], variant_col:legal_name from notation_issue;
/* This does not raise an error */
select variant_col['0.text'], variant_col:legal_name from notation_issue;
/* This also does not raise an error */
select variant_col:"0.text", variant_col:legal_name from notation_issue;

When using the !! operator in Map Sonar cube issues warning [s6611 "Map" values should be accessed safely][1]. One solution from Sonar is to use getValue, which will throw a NoSuchElementException if the key is not found.
val a = mapOf<Int, Map<String, String>>()
a[999]!!["x"] // NullPointerException
a.getValue(999)["x"] // NoSuchElementException: Key 999 is missing in the map.
What is the benefit of NoSuchElementException other than reporting the value of a key that is not found?
[1]: https://rules.sonarsource.com/kotlin/RSPEC-6611/ |
Why is NoSuchElementException preferred over NullPointerException when retrieving from a Map? |

I have a C#/Blazor project where i use tailwindcss for the user interface. Visual Studio highlights the @apply directives in the .css files from tailwind as unkown @-blocks. Are there any ways to teach Visual Studio about them, disable this warning or replace @apply by some known directives?
Example:
```
table {
@apply table-fixed inline-block border-collapse overflow-hidden border border-gray-dark rounded;
}
```
For the *@tailwindcss* directives i used the replacements *@import 'tailwindcss/base';* and so on.

I thought I could easily display a toolbar in UIKit, but I was wrong, or at least I can't do so without getting "Unable to simultaneously satisfy constraints." console messages.
Here is my code:
```swift
import UIKit
class ViewController: UIViewController {
let toolbar = UIToolbar()
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .systemBackground
toolbar.items = [
UIBarButtonItem(title: "Title", style: .plain, target: nil, action: nil),
UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
]
view.addSubview(toolbar)
toolbar.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
toolbar.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor),
toolbar.leadingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leadingAnchor),
toolbar.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor),
toolbar.heightAnchor.constraint(equalToConstant: 44)
])
}
}
```
And here is the console log:

I tried giving the toolbar a frame rather than constraints, and also to not give it an explicit height.
The only thing that works is to comment out `UIBarButtonItem(title: "Title", style: .plain, target: nil, action: nil)`, which isn't really a solution.
What am I doing wrong? |

Say I have a vector of some generic T objects:
std::vector<T> vector_of_ts = {...};
That vector is basically a heap-allocated array of T objects, under the hood. Now, say I have the following:
std::unique_ptr<T> t = std::make_unique<T>(...);
Again, this is a heap-allocated T object under the hood. Is it possible to push back that object to the vector *by moving it*, without making temporary/extra copies? Something like:
vector_of_ts.move(*t) |
Can I move a std::unique_ptr<T> into a std::vector<T>? |

My task is to create a tool that, based on (specific) input data, will generate a 'grid' of employees' working hours and spit out specific shifts 6-14; 7-15; 10-20 etc etc.
The general operation of such a macro, let's say I have one, the problem begins when the macro must have a requirement that in a given row (the row is one employee) the sum cannot be greater than 10.
Below I paste the code I managed to create, which fills in the values accordingly based on the input data, but without this requirement (row sum not greater than 10).
```
Sub AutoFill()
Dim ws As Worksheet
Dim col As Integer
Dim row As Integer
Dim suma As Integer
Dim liczba_osob As Integer
' Ustaw arkusz, na którym chcesz działać
Set ws = ThisWorkbook.Sheets("01")
' Wyczyść zakres G5:AD36
ws.Range("G5:AD36").ClearContents
' Iteruj przez kolumny od G do Y
For col = 7 To 30
' Pobierz liczbę osób w pracy w danej godzinie
liczba_osob = ws.Cells(2, col).Value
' Ustaw sumę kolumny na 0
suma = 0
' Uzupełnij komórki wartością 1 do momentu, gdy suma wiersza będzie równa liczbie osób w pracy
For row = 5 To 36
' Sprawdź, czy suma nie przekracza liczby osób w pracy
If suma < liczba_osob Then
ws.Cells(row, col).Value = 1
suma = suma + 1
Else
' Jeśli suma przekroczyła liczbę osób w pracy, zostaw komórkę pustą
If Not IsEmpty(ws.Cells(row, col)) Then
ws.Cells(row, col).ClearContents
End If
End If
Next row
Next col
End Sub
```
There are also screenshots below in the attachments - in one there is the addition of "1" by the macro, in the other the addition of "1" by me in the way the macro should be supplemented.
Yes, as part of the implementation, the number of employees in each hour is given in the G2:AD2 range, and the hours are listed in G1:AD1.
Can anyone help me or guide me somehow to make it work?
Unless it is possible to completely omit all these "1"s and directly generate individual changes 6-14, 7-15, etc. based on the demand given in G2:AD2...

being pretty new to **Scala** can any one please kindly help me with a scenario where I need to get the file with latest modified date.
There are two scenarios. consider 2 directories ,
- **dir1** (which has sub directories and files present inside each sub directory )
- **dir2** (no sub directories but has only files )
for Scenario 1 - I need to get the file with latest modified date inside a latest modified date directory
for Scenario 2 - I just need the latest file with latest modified.
Please do help me in any way possible, I tried experiments with **java.io** file handling but haven't made any good progress.

I'm relatively new to using neo4j. I've connected to a database with the py2neo library and populated the database with the faker library to create nodes for Person and Address each with attributes attached to them. I'm interested in creating indexes and testing the performance of different indexes. Before I get to that point, I created some indexes and used the command
```
`graph.run("SHOW INDEXES;")`
```
[Output][1]
I was expecting 2 indexes to show but 3 indexes returned. The final one was a Look up type and had some null properties. That attached image shows the output, Why is this index showing up? Thanks.
I was expecting only 2 to return, so I'm thinking maybe this is some lack of understanding on my part? I've started reading through the Neo4j documentation on indexes but I'm still unsure. Any help would be appreciated. Thanks!

I'm trying to create a pod that runs Kafka and ZooKeeper and connect to it via Python. However, with my current configuration, I'm unable to send or receive messages from the Python client, although I can successfully connect to the port exposed by Kafka.
I'm currently experiencing issues with my pod configuration. I've defined topics and checked in Lens which port the Kafka service exposed. I can confirm that it's connecting to Kafka, but when I send messages from a producer and access the container, none of them arrive. Similarly, no information is received from the consumer. I've already ruled out errors related to ports or topics as I've checked them thoroughly.

Having a dataset like this:
|Index|Role|Name|Grade|
|---|---|---|---|
|1|Provider|Alex|7|
|2|Provider|William|7.5|
|7|Provider|Juan|5.5|
|15|Provider|Pedro|4.5|
|25|Client|George|8|
|26|Provider|Mark|9.4|
|37|Client|James|8.1|
|39|Transporter|Anthony|9.5|
|50|Transporter|Jason|7|
I'm trying to group the consecutive rows with same **Role** value. I can achieve this by using the following sentence:
df = df.groupby((df.Role!= df.Role.shift()).cumsum()).agg(
Role = ('Role', 'first'),
Name = ('Name', ' '.join),
Grade = ('Grade', 'mean')
).reset_index(drop=True)
This would leave the dataframe looking like this:
|Index|Role|Name|Grade|
|---|---|---|---|
|1|Provider|Alex William Juan Pedro|6.125|
|2|Client|George|8|
|3|Provider|Mark|9.4|
|4|Client|James|8.1|
|5|Transporter|Anthony Jason|8.25|
Now I would like to add a new rule. I would like to only group when the dataframe index has a difference of 5 units at maximum from previous row:
|Index|Role|Name|Grade|
|---|---|---|---|
|1|Provider|Alex William Juan|6.67|
|2|Provider|Pedro|4.5|
|3|Client|George|8|
|4|Provider|Mark|9.4|
|5|Client|James|8.1|
|6|Transporter|Anthony|9.5|
|7|Transporter|Jason|7|
How could I achieve this? Also if there is any grouping method more efficient, it is welcome. |

In Delphi 7 I have a report written in QuickReport.
The report is called by the function from another form
~~~
var RepResult : integer
RepResult := ShowReport(param1,param2...);
~~~
The function inside report looks like
~~~
` var QuickRep1 : TQuickReport;
ReportResult : integer;
function ShowReport(param1,param2...) : integer
begin
...
QuickRep1.PreviewModal;
Result := ReportResult;
end;`
~~~
The calculation of variable ReportResult is complicated, based on many queries inside QuickReport and calculated in events of DetailBands, ChildBands ,LoopBands and so on .
The report and the calculations works fine , but now the customer wants to see result of this calculations in another place without viewing the report.
So the question is : Is it possible to get only the result of the function without previewing or printing the report ?
I tried QuickRep1.PreviewModeless and quickrep1.print to non-existed printer. Nothing works |

it depends on how many bg images you have specified
.box {
background-image: url(image1.png), url(image2.png);
background-color: blue;
}
in the above there are 3 bg layers |
You can use ModuleType:
from types import ModuleType
a = ModuleType("some") # name of obj
a.foo = 123
print(a.foo)
print(a.__name__) # some
a.__dict__
# {'__name__': 'some', '__doc__': None, '__package__': None, '__loader__': None, '__spec__': None, 'foo': 123}
Though name will be mandatory, but you can replace it by some placeholder:
a = ModuleType(".")
b = ModuleType(".")

`psycopg2.errors.UndefinedObject: operator class "gin_trgm_ops" does not exist for access method "gin"`
Hello everybody, this is the whole message when I try to run pytest on my project which is written in Python/Django + db is postgresql and all sitting inside docker.
I build a project on docker with django-cookiecutter template, all settings are default. I put a gin index to one of my string fields, migrations running successfully, `pg_trgm` extention is being created successfully, but if I try to test my project with pytest I got this error.
Here is my `pytest.ini`
```
[pytest]
DJANGO_SETTINGS_MODULE = config.settings.test
```
Here is my test settings file's database configuration: `test.py`
```
DATABASES['test'] = { # noqa
'ENGINE': 'django.contrib.gis.db.backends.postgis',
'NAME': 'test',
'PASSWORD': 'test',
'USER': 'test',
'HOST': 'localhost',
'PORT': 5454,
}
```
This is part of the migration which creates the extention `pg_trim` and puts an index to the field given
```
migrations.AddIndex(
model_name='<model_name>',
index=django.contrib.postgres.indexes.GinIndex(fields=['field_name'], name='field_name_gin_idx', opclasses=['gin_trgm_ops']),
),
```
And this is the whole traceback which I am getting:
```

But only when I run a test no matter its django's `manage.py test` or `pytest` it fails with the error above. If I comment out the part of migration which should generate an index it works. |

I am trying to convert string of mathematical expression to lambda function in C++17. How can I do this type of conversion with function?
std::function<void()> str2lambda(const std::string& str) {
// Conversion
// return lambda function
}
Example:
> Input Mathematical function:
> "x^2+1"
>
> Output Lambda Function:
> `auto func = [](float x) -> float { return pow(x, 2) + 1; }; ` |

sorry for maybe the stupid question but can't wrap my head around this one.
I want to create a smooth linear plot or a histogram, for my 8 samples looking at the distribution of length of their gene transcription (x axis), and how frequently this length appears in each of the samples (y).
I've binned the log10 of my gene lengths, but then I'm stuck. I cant plot a histogram as then it just says they're all the same (all the genes appear in all of the samples), and I'm not sure how to include the expression value for the experiments in this.
Any suggestions would be appreciated!

Since version 1.17 go no longer loads the entire module graph, but, with the introduced concept of pruned graph, only a part of it. A pruned graph can be viewed using `go mod graph`. However, when I want to see the selected module version within that pruned graph using `go list -m all`, it traverses the entire graph and prints the selected versions for all modules (including the ones that are not part of the pruned graph).
Is there a way to get/print selected versions **only for the modules inside (within) the pruned graph**? Any go command/tool.
Thank you! |

The list you shared as output is not valid as list cannot be a key value pair. Did you mean this - a dict of dicts?
{
1: {
"B4": 14,
"B5": 12
},
2: {
"B4": 58,
"B5": 54
},
}
To get that -
import json
with open("file/path.json") as file:
data = json.load(file) # Output a list of dict
dict_with_index = dict(zip(range(1,len(data) + 1), data))

You terminate a process by calling [`TerminateProcess()`](https://learn.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-terminateprocess). Doing so will terminate the target process if the caller holds sufficient privileges. This works for any process, not just child processes.
But before you go there, you first need to understand how [`CreateProcessW()`](https://learn.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-createprocessw) works. The documentation explains the semantics in detail. The return value, in particular, differs from what the code in question assumes. |
Client-side caching is usually done in memory for speed. If your data can't fit in memory, then you'll need to write it to the local drive or send it to the back-end.
Since the local file storage is unavailable in the Unity3D Web Player, you'll have to either send it to some sort of back-end or develop and in-memory store by hand.

I'm using the code example by [David Hamrick][1] to monitor a file using GCD.
int fildes = open("/path/to/config.plist", O_RDONLY);
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_source_t source = dispatch_source_create(DISPATCH_SOURCE_TYPE_VNODE,fildes,
DISPATCH_VNODE_DELETE | DISPATCH_VNODE_WRITE | DISPATCH_VNODE_EXTEND | DISPATCH_VNODE_ATTRIB | DISPATCH_VNODE_LINK | DISPATCH_VNODE_RENAME | DISPATCH_VNODE_REVOKE,
queue);
dispatch_source_set_event_handler(source, ^
{
//Reload the config file
});
dispatch_source_set_cancel_handler(source, ^
{
//Handle the cancel
});
dispatch_resume(source);

I have a page similar to this:
File: `[pid].tsx`
type ProblemPageProps = {
problem: Problem
};
const ProblemPage:React.FC<ProblemPageProps> = ({problem}) => {
...
return (
<div>
<Workspace problem={problem} />
</div>
);
}
export default ProblemPage;
export async function getStaticPaths() {
const paths = Object.keys(problems).map((key) => ({
params: {pid:key}
}))
return {
paths,
fallback: false
}
}
export async function getStaticProps({params}: {params: {pid: string}}) {
const {pid} = params;
const problem = problems[pid];
if (!problem) {
return {
notFound: true
}
}
return {
props: {
problem
}
}
}
In `Workspace` I have something like this - gets triggered on a click of a button:
const handleCodeReset = () => {
setUserCode(problem.starterCode);
};
And I have one function to push to the **same** `[pid].tsx` page but with a different PID:
const handlePreviousProblemChange = () => {
router.push(`/problems/my_second_problem`);
}
Being triggered by:
<div onClick={() => handlePreviousProblemChange()}>
BLA BLA BLA
</div>
When that happens, `problem` is pointing to `my_second_problem` which is exactly what I need but during `onClick` event, `problem.starterCode` still points to the previous `pid`. What can I do to make sure `problem.startedCode` gets referenced in the right way? |

I tried to simplify your code, and ended up with:
import vobject
s = 'BEGIN:VCARD\r\nFN:John Smith\r\nN:Smith;John;;;\r\nEND:VCARD'
vobj = vobject.readOne(s)
vobj.add('bday')
vobj.prettyPrint()
vobj.bday.value = '1931-02-10'
vobj.prettyPrint()
which produced:
> python test.py
VCARD
FN: John Smith
N: John Smith
BDAY:
VCARD
FN: John Smith
N: John Smith
BDAY: 1931-02-10
>
which seems to be what was expected.
**Question 1**
There's not generally a need for arbitrary names in vObjects, because the specifications dictate what values are required, and they're all handled by the *vobject* code.
A common pattern when adding a value is to save a reference to the added attribute, and access it directly, like:
notes = vobj.add("NOTES")
notes.value = "The content of my notes"
or, just do it inline:
vobj.add("NOTES").value = "Notes in one line"
Or you can access it directly:
vobj.notes.value = "New notes content"
**Question 2**
The problem here is nothing to do with *vobject*, but rather with Python. In Python, `eval` only works for *expressions*. To dynamically compile and execute a *statement* (like your `stmnt2`), you need to use `exec`.
If you change
eval(stmnt2)
to
exec(stmnt2)
your example code sets the BDAY property without an exception.
See https://stackoverflow.com/questions/2220699/whats-the-difference-between-eval-exec-and-compile for a full explanation.
**Question 3**
Yes, it matters. The type of values of the various attributes of a vObject are determined by the specifications. Some have a single value, others are (optionally) a set of values. *vobject* doesn't enforce this, currently. |

There are multiple mistakes in your attempt… Try the following for small screen devices *(I have used a random color that you will replace with the right desired one)*:
``` css
/* For larger screens (first) */
.woocommerce-info {
background-color: #000000 !important;
}
/* For smaller screens (after) */
@media screen and (max-width: 782px) {
.woocommerce-info {
background-color: #AA00B6 !important;
}
}
```
Code goes in *style.css* file of your active child theme (or active theme).
Tested and works. You may try without `!important`, to see if it works...
On small screen devices, you will get something like:
[![enter image description here][1]][1]
On larger screen devices, you will get the default behavior like:
[![enter image description here][2]][2]
-------
In some cases, you may insert those CSS rules after all existing ones using:
```php
add_action('wp_head', 'wp_head_custom_css', 99999);
function wp_head_custom_css() {
?>
<style>
/* For larger screens (first) */
.woocommerce-info {
background-color: #000000 !important;
}
/* For smaller screens (after) */
@media screen and (max-width: 782px) {
.woocommerce-info {
background-color: #AA00B6 !important;
}
}
</style>
<?php
}
```
Code goes in functions.php file of your active child theme (or active theme). Tested and works.

I created a short python application in a Google Colab notebook, that works fine. I am trying to move the application from Google Colab into a local Docker-Python-Application.
But whenever **I run the application with Docker and do in a .py file**
```
from llama_parse import LlamaParse
```
**My application fails with the following error:**
