Another possible solution, which first creates a list of `1` or `-1` from each value of column `Integer_Column` and then uses [`explode`][1]:
(df.assign(Integer_Column = df['Integer_Column']
.map(lambda x: [np.sign(x)]*abs(x)))
.explode('Integer_Column'))
----------
The following solution seems to be a little bit more efficient, but not much, because of [`explode`][1], as @mozway pertinently argues in a comment below.
signs = np.sign(df['Integer_Column'])
lengths = abs(df['Integer_Column'])
(df.assign(Integer_Column = [np.full(abs_len, sign)
for sign, abs_len in zip(signs, lengths)])
.explode('Integer_Column'))
----------
Output:
String_Column String_Column_2 Integer_Column
0 A X 1
1 B Y -1
1 B Y -1
2 C Z 1
2 C Z 1
2 C Z 1

I want to know which approach is better in which scenario:
1) React custom hooks for http requests, where we put states for loading, error and data and then inside functional component we just use that hook get data and then render it to ui and/or save it to redux.
for example:
```javascript
const useFetch = (query) => {
const [status, setStatus] = useState('idle');
const [data, setData] = useState([]);
useEffect(() => {
if (!query) return;
const fetchData = async () => {
setStatus('fetching');
const response = await fetch(
`https://hn.algolia.com/api/v1/search?query=${query}`
);
const data = await response.json();
setData(data.hits);
setStatus('fetched');
};
fetchData();
}, [query]);
return { status, data };
};
```
2) Or we should use redux or redux toolkit's middleware to do http or any async work and then dispatch an action in that middleware to update redux store.
for example:

currently, I install mongodb on the C Drive and everytime I use backend to store something in mongodb, it will be automatically stored in the same folder as mongodb, which is C:/.
But my next project will have to store a huge data of video and image, and if i keep save it on C:/, it will be full in no time.
How can I config mongo and express so that my data will be stored in E:/(External memory)
I don't want to install mongo on E:/, just want to store data on E:/, to save memory for my C drive |

You can use your same code with only one changes. You are mentioned format as "WEBP "in capital letters. Just change "webp" (lowercase) as shown here .
Your code
```
from PIL import Image
import glob, os
for infile in glob.glob("*.jpg"):
file, ext = os.path.splitext(infile)
print(file)
im = Image.open(infile).convert("RGB")
im.save(file + ".webp", "webp")
```
Formatting reference is given below please check it.
[![References][1]][1]
Note - We are unable to use Broken or corrupted images. In these formats (.png,.jpg,.jpeg). It will throws error. Handle with try and except.
Also, i checked the above code, works in Windows and Ubuntu OS (Linux)
Tested Code
```
from PIL import Image
import glob, os
for infile in glob.glob("images/*.jpg"):
file, ext = os.path.splitext(infile)
print(file)
im = Image.open(infile).convert("RGB")
im.save(file + ".webp", "webp")
```

The buffer has been removed from the benchmark and `black_box()` is used in order to pretend the parameter is unpredictable and the result is used.
The sequence of bytes has been made longer in order to let the algorithms actually work, and the invocations are repeated many times in order to introduce bigger differences in the results.
Comparing `v_0` and `v_1` shows that a substantial part of the time is spent in checking the utf8 string.
`v_2` is probably disappointing because of its `pow()` operation.
`v_3` is clearly faster, but it does not check anything; the result could be meaningless because the bytes could contain anything but digits, and the resulting integer may also overflow if the sequence is too long!
`v_4` is similar to `v_3` but considers an eventual starting `-` sign (because an `i32` is expected, not an `u32`); this first check does not seem to be too detrimental to performances.
If we are absolutely certain that the sequence of bytes is correct, then we could lean towards the fastest version (`v_3` or `v_4`), but in any other situation we should [definitely prefer](https://www.reddit.com/r/Jokes/comments/5g2ay4/interviewer_i_heard_you_were_extremely_quick_at/) `v_0`.

I want to create a Live Chat web widget - component, that can be embedded on ecommerce website and allow business owner to talk to users/customers (like Intercom). In my architecture design, I figured out that I need to store some kind of secret/token, that identifies conversation. System should remember conversation when user returns to ecommerce after some time.
However I don't know where to put such a secret token (my web widget is loaded via iframe). Should I use localStorage? Or something else? |

I'm working on some code for a javascript implemenation of Conway's Game of Life Cellular Automata for a personal project, and I've reached the point of encoding the rules. I am applying the rules to each cell, then storing the new version in a copy of the grid. Then, when I'm finished calculating each cell's next state, I set the first grid's state to the second's one, empty the second grid, and start over. Here's the code I used for the rules:
```lang-js
//10x10 grid
let ecells = [[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]];
let cells = empty_cells;
let new_cells = cells;
let paused = true;
function Cell(x, y) {
return cells[y][x];
}
function Nsum(i, j) {
if (i >= 1 && j >= 1) {
return Cell(i - 1, j) + Cell(i + 1, j) + Cell(i, j - 1) + Cell(i - 1, j - 1) + Cell(i + 1, j - 1) + Cell(i, j + 1) + Cell(i - 1, j + 1) + Cell(i + 1, j + 1);
}
}
//One can manually change the state of the cells in the "cells" grid,
//which works correctly. Then, one can run the CA by changing the "paused"
//value to false.
function simulation() {
for (i = 0; i < cells[0].length; i++) {
for (j = 0; j < cells.length; j++) {
if (Cell(i, j)) {
ctx.fillRect(20*i - 0.5, 20*j, 20, 20);
if (!pause) {
if (Nsum(i, j) == 2 || Nsum(i, j) == 3) ncells[j][i] = 1;
else ncells[j][i] = 0;
}
}
else {
ctx.clearRect(20*i - 0.5, 20*j, 20, 20);
if (!pause) {
if (Nsum(i, j) == 3) ncells[j][i] = 1;
else ncells[j][i] = 0;
}
}
}
}
if (!pause) cells = ncells;
ncells = ecells;
requestAnimationFrame(simulation);
}
simulation();
```
The rule logic is inside the nested for loop, Nsum is the function that calculates the neighborhood sum of the current cell. I say ncells[j][i] instead of ncells[i][j] because in a 2d array you address the row first.
I didn't try much, but I can't imagine a solution. Help! |

I am receiving a json string of the form
```json
{
"people": [
{
"Freddie": {
"surname": "Mercury",
"city": "London"
}
},
{
"David": {
"surname": "Bowie",
"city": "Berlin"
}
}
]
}
```
with the ultimate goal of recovering them as Proto messages of the kind
```
message Person {
optional string name = 1;
optional string surname = 2;
optional string city = 3;
}
message Msg {
repeated Person people = 1;
}
```
What is the best practice - i.e. short of custom adhoc logic of manipulating the keys - to convert the above json string to a string
sich as
```
{
"people": [
{
"name": "Freddie",
"surname": "Mercury",
"city": "London"
},
{
"name": "David",
"surname": "Bowie",
"city": "Berlin"
}
]
}
```
so that the correspondence between the json
and the Proto is one-to-one, and therefore out-of-the-box deserializers could be used?

I confirm I can connect locally using the IJ connection manager

I am now trying to connect so I have the following config from my spring app
```yaml

read-timeout-millis: 30000 # 30 seconds
```
and I even use a function to make sure it is up first (I also added logic to test the keyspace is available as well)...
```java
@SpringBootApplication
public class BackendApplication {
private static final Logger log = LoggerFactory.getLogger(BackendApplication.class);
public static void main(String[] args) {
waitForCassandra();
SpringApplication sa = new SpringApplication(BackendApplication.class);
sa.addBootstrapRegistryInitializer(new MyBootstrapInitializer());
sa.run(args);
}
private static void waitForCassandra() {
CqlSessionBuilder builder = CqlSession.builder();
AtomicInteger attempts = new AtomicInteger();
try (ScheduledExecutorService executor = Executors.newSingleThreadScheduledExecutor()) {
executor.scheduleAtFixedRate(() -> {
try (CqlSession session = builder.build()) {
ResultSet rs = session.execute("SELECT keyspace_name FROM system_schema.keyspaces WHERE keyspace_name = 'cbusha';");
if (rs.one() != null) {
executor.shutdown();
} else {
if (attempts.incrementAndGet() >= 12) { // 12 attempts * 10 seconds sleep = 2 minutes
log.error("Keyspace cbusha does not exist - exiting after 2 minutes");
System.exit(1);
}
log.debug("Keyspace cbusha does not exist - sleeping");
}
} catch (Exception e) {
if (attempts.incrementAndGet() >= 12) { // 12 attempts * 10 seconds sleep = 2 minutes
log.error("Cassandra is unavailable - exiting after 2 minutes");
System.exit(1);
}
log.debug("Cassandra is unavailable - sleeping");
}
}, 0, 10, TimeUnit.SECONDS);
}
log.info("Cassandra is up - executing command");
}
}
```
But when I try to start on docker I see the connection is accessible
```
2024-03-24 13:33:45 17:33:45.055 [main] INFO com.cbusha.be.BackendApplication -- Cassandra is up - executing command
```
However, further down when it tries to create the channel I get the errors in [this gist][2].
I see it is using the proper profile and the docker dns is resolving here `endPoint=cassandra/172.26.0.4:9042`
If I restart the container a little later it works.
Why is this and is there a way to confirm the channel will work before starting similar to the connection?

I have a table with a string column that is formatted as json. I want to query my table by json. This is achievable with SQL
```
SELECT *

Is it possible with GraphQl and Hot Chocolate?
I tried
```
public IQueryable<Class> GetById([ScopedService] AppDbContext context, string id)
{
return context.Classes.AsQueryable().Where(p => JObject.Parse(p.JsonCol)["id"].ToString() == id);

```
Got an error:
"message": "The LINQ expression 'DbSet<Platform>()\r\n .Where(p => JObject.Parse(p.JsonCol).get_Item(\"id\").ToString() == __id_0)' could not be translated.
Any help would be appreciated.

Locally run `ansible-lint` `pre-commit` behaves differently than run during CI/CD.
I use following
```yaml
---
repos:
- repo: https://github.com/ansible/ansible-lint
rev: v24.2.1
hooks:
- id: ansible-lint
```
That is because `/etc/ansible/ansible.cfg` is available locally which also configures e.g. collection path where private collections are installed.
During the `ansible-lint` run a `requirements.yml` is picked up such that dependencies would be installed. Since the collections are private, I would need to hardcode an access token which seems wrong to me. I tried using
```yaml
---
collections:
- name: "git+https://<token name>:${token}@<private git repo"
type: git
version: "*"
```
and setting `export token=<token with access>` but this did not work.
I also tried to use a `.ansible-lint` config with
```yaml
---
mock_modules:
- <namespace>.<name>.<role>
```
or
```yaml
mock_roles:
- <namespace>.<name>.<role>
```
but not if it helped.
Related questions:
- How do I make `ansible-lint` `pre-commit` behave the same locally and during CI/CD?
- How to ignore locally available config?
- How to specify authentication in `requirements.yml`, e.g. via an environment variable?

I have a task to submit on greedy algorithms. I wrote this code but I'm not sure what the time complexity of the algorithm is. This problem called "Rectangle Covering".
This is the code:
```
MinGreedyCutReg(R[])
cut[] = null
while R != null
endIndex = 0
for i = 0 to R.length-1
if(endIndex < R[i].r)
endIndex = R[i].r
maxCount = 0
maxIndex = 0
for i = 0 to endIndex
updateMax = 0
for j = 0 to R.length - 1
if(R[j].l <= i and R[j].r >= i)
updateMax++
if(updateMax > maxCount):
maxCount = updateMax
maxIndex = i
cut.add(maxIndex)
for i = 0 to R.length - 1
if(R[i].l <= maxIndex and R[i].r >= maxIndex)
R.remove(i)
return cut
```
I am trying to find the time complexity of the algorithm. I think it is O(n * m) because of the nested loop. My friend tells me it is O(n^2) due to this nested loop. So basically I think the question is what time the nested loops can do and why. |

so as per [matias-quaranta][1] comment, this is a duplicate of [cosmos-db-trigger-is-not-being-run-when-inserting-new-document][2].
Currently CosmosDB does not work how a sane person would normally think, you need an SDK to trigger a pre or post trigger. Not Even the REST API can accept the trigger as a param. Just, the SDK.
Glad i didn't spend more than the last 3 days in trying to figure this thing out.
Thank you [matias-quaranta][1]

There seems to be a bug with SwiftUI's [`TabView`](https://developer.apple.com/documentation/swiftui/tabview) when used with [`.tabViewStyle(.page)`](https://developer.apple.com/documentation/swiftui/tabviewstyle/page) and any animated `.transition()` that moves the view horizontally (e.g. [`.move(edge: .leading/.trailing))`](https://developer.apple.com/documentation/swiftui/anytransition/move(edge:)), [`.slide`](https://developer.apple.com/documentation/swiftui/anytransition/slide), [`.offset()`](https://developer.apple.com/documentation/swiftui/anytransition/offset(x:y:)), etc.) in landscape orientation.
When the tab view transitions in, the content appears off-center and the animation goes back and forth before it stabilizes.
Did anyone else experience this and is there any known workaround?
[![TabViewTransitionBug][1]][1]
```swift
import SwiftUI
struct ContentView: View {
@State private var showTabView = false
var body: some View {
VStack {
Button("Toggle TabView") {
showTabView.toggle()
}
Spacer()
if showTabView {
TabView {
Text("Page One")
Text("Page Two")
}
.tabViewStyle(.page)
.transition(.slide)
}
}
.animation(.default, value: showTabView)
.padding()
}
}
#Preview {

}
@main
struct TabViewTransitionBugApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
```
Tested on Xcode 15.3 (15E204a), iOS 17.3.1 iPhone, iOS 17.4 Simulator.
*Bug report `FB13687638` filed with Apple.*
## Update
It seems to be related to safe areas as it doesn't happen on Touch ID devices.
[![TabViewTransitionBugNoSafeAreas][2]][2]
## Update
As suggested in the answer below, adding `.ignoresSafeArea(edges: .horizontal)` on the TabView, changing the animation to `easeInOut` and removing the `.padding()` from the VStack fixes the initial transition, but swiping between tabs is now off-center.

i want to establish one way tls authentication system between app service and function app.
Inside app service and function app i've uploaded private and public certificates from "certificate" blade.
now whenever i make request to function app api i get 403, which certificate (private/public) should i send in request header (X-ARR-ClientCert), should i do this step manually from code ? if yes then what's the purpose of uploading certificates from "certificate" blade and how to load them from nodejs? this is how i'm invoking function app api from app service:
const response = await axios.get(
"https://test-az-fn.azurewebsites.net/api/HttpTrigger1"
);
i've enabled client certificate mode to "required" as shown below inside function app,
added "WEBSITE_LOAD_CERTIFICATES" inside application settings of app service.

I've been working on a Python discord bot and wanted to containerize it, which has worked pretty well, but while testing one of the features (bot -> open API) via HTTPS using the http3 package and I'm getting the following error:
```
ssl.SSLError: Cannot create a client socket with a PROTOCOL_TLS_SERVER context (_ssl.c:811)
```
I've read various articles and tutorials online but they either seem to half answer my question or partially relate to other applications altogether, such as configuring Nginx, which I think is just muddying the water a little.
So far I've encountered people mentioning to create and move some certs and one answer saying to include `--network host` into the `Dockerfile`, but it doesn't seem like there is any issue with the network connectivity itself.
I was tempted to just change the request URL to use HTTP instead as there's no credentials or sensitive data being transmitted but would feel a lot more comfortable knowing it's using HTTPS instead.
My Dockerfile is as below (note: I added the `RUN apt-get update ...` block after my investigations hoping that would generate a certificate and the error would magically clear up but that's not the case).
```lang-docker
FROM python:3.10-bullseye
COPY requirements.txt /app/
COPY ./bot/ /app
RUN apt-get update \
&& apt-get install openssl \
&& apt-get install ca-certificates
RUN update-ca-certificates
WORKDIR /app
RUN pip install -r requirements.txt
COPY . .
CMD ["python3", "-u", "v1.py"]
```
I tried a little bit basic of diagnostics through the container like checking the directories for certs and trying to curl to a HTTPS URL. |
Looks like there's an already accepted answer. But @user23919330 was onto something. The most obvious idea would be to convert this:
for (size_t i = 0; i < SIZE; i++, a_ptr++, b_ptr++, c_ptr++, data++) {
*a_ptr = data->a;
*b_ptr = data->b;
*c_ptr = data->c;
}
To this:
for (size_t i = 0; i < SIZE; i++) {
a_ptr[i] = data[i].a;
}
for (size_t i = 0; i < SIZE; i++) {
b_ptr[i] = data[i].b;
}
for (size_t i = 0; i < SIZE; i++) {
c_ptr[i] = data[i].c;
}
That is, let each read and write from sequential addresses. Take advantage of caching. Trying this out now....
**Update**. I modified OP's code such that it would run multiple times and it would print the timings (in milliseconds)
```
int testrun() {
DWORD start, end;
Struct* data = malloc(sizeof(Struct) * SIZE);
for (size_t i = 0; i < SIZE; i++) {
data[i].a = i;
data[i].b = i;
data[i].c = i;
}
start = GetTickCount();
for (int i = 0; i < 500000; i++) {
do_work(data);
}
end = GetTickCount();
printf("%u\n", end - start); // print the number of milliseconds
free(data);
}
int main() {
for (int j = 0; j < 10; j++) {
testrun();
}
}
```
Compiled for release and got these run times:
5344
5953
5438
5718
5282
4531
4578
4609
4532
4500
Or just about 5 seconds on average per test test runs. Now let's see what happens when I change `do_work` to be this:
```
void do_work(Struct* data) {
int32_t* a = malloc(sizeof(int32_t) * SIZE),
*b = malloc(sizeof(int32_t) * SIZE),
*c = malloc(sizeof(int32_t) * SIZE);
int32_t* a_ptr = a, *b_ptr = b, *c_ptr = c;
for (size_t i = 0; i < SIZE; i++) {
a_ptr[i] = data[i].a;
}
for (size_t i = 0; i < SIZE; i++) {
b_ptr[i] = data[i].b;
}
for (size_t i = 0; i < SIZE; i++) {
c_ptr[i] = data[i].c;
}
free(a);
free(b);
free(c);
}
```
Recompiled and ran and got these times:
2406
2344
2328
2266
2344
2359
2266
2328
2359
2266
Or 2.3 seconds on average. I say there's a case to be made about taking advantage of sequential addresses. |
I'm trying to setup a scheduled task with ECS Fargate.Task was dockerized and will be run through AWS ECS with Fargate. Unfortunately the service I want to run needs to access an API of a partner where the IP needs to be whitelisted. I see that for each execution of the task with Fargate a new ENI with an different IP is assigned.
How is it possible to assign a static IP to a AWS ECS Fargate Task?

How can I have an ECS Fargate scheduled job access API with a ip whitelist policy? |

Use this:
select jsonb_object_keys(json_stuff) from table;
(Or just `json_object_keys` if you're using just JSON.)
The PostgreSQL JSON documentation is quite good. [Take a look](http://www.postgresql.org/docs/9.5/static/functions-json.html).
And as it is stated in the documentation, the function only gets the outer most keys. So if the data is a nested JSON structure, the function will not return any of the deeper keys.

I was getting the exact same error, while pushing my code on github. Then I went to github discussions.
Solution - The slow or incosistent internet connection may cause this problem, make sure you've steady and fast internet connection, or it'll give you -

I have a table that I created using angular-slickgrid AngularGridInstance in that I can add new columns, reorder the columns, shrink and expand the columns
If I expand the columns too much that it goes beyond the screen then a Horizontal scroll bar comes which is fine.
However, when I shrink columns excessively, a gap appears on the right side, which is undesirable. How can I ensure that the last column covers any gap created by shrinking columns?
I tried using forceFitColumns = true. But if I use that then it causes problems when I expand the columns other columns get shrunk and no scroll bar is displauyed. So I was thinking is there any possible way in which I can forceFitColumns and can have Horizontalscroll bar bothe at the same time. |
Is it possible to have forceFitColumns and horizontalScrollBar both at the same time |

I'm trying to Implement a K-means algorithm, with semi-random choosing of the initial centroids.
I'm using Python as a way to process the data using numpy to choose initial centers and stable API in order to implement the iterative part of K-means in C.
However, when I am entering relatively large datasets, I get Segmentation Error (core dumped), so far I tried to manage memory better and free all the Global array before go back to python, also I tried to free all local array before end of the function.
this is the code in python:
```
def Kmeans(K, iter , eps ,file_name_1, file_name_2):
compound_df = get_compound_df(file_name_1,file_name_2)
N , d = int(compound_df.shape[0]) , int(compound_df.shape[1])
data = np.array(pd.DataFrame.to_numpy(compound_df),dtype=float)
assert int(iter) < 1000 and int(iter) > 1 and iter.isdigit() , "Invalid maximum iteration!"
assert 1 < int(K) and int(K) < N , "Invalid number of clusters!"
PP_centers = k_means_PP(compound_df,int(K))
actual_centroids = []
for center_ind in PP_centers:
actual_centroids.append(data[center_ind])
actual_centroids = np.array(actual_centroids,dtype=float)
data = (data.ravel()).tolist()
actual_centroids = (actual_centroids.ravel()).tolist()
print(PP_centers)
print(f.fit(int(K),int(N),int(d),int(iter),float(eps),actual_centroids,data))
```
this is the code in C, that manages the ```PyObject``` creation, this is the python object being returned to the ```Kmeans``` function
```
PyObject* convertCArrayToDoubleList(double* arr){
int i, j;
PyObject* K_centroid_list = PyList_New(K);
if(!K_centroid_list)
return NULL;
for(i=0;i<K;++i){
PyObject* current_center = PyList_New(d);
if(!K_centroid_list){
Py_DECREF(K_centroid_list);
return NULL;
}
for(j=0;j<d;++j){
PyObject* num = PyFloat_FromDouble(arr[i*d+j]);
if(!num){
Py_DECREF(K_centroid_list);
Py_DECREF(current_center);
return NULL;
}
PyList_SET_ITEM(current_center,j,num);
}
PyList_SET_ITEM(K_centroid_list,i,current_center);
}
return K_centroid_list;
}
```
I ran valgrind on some samples, there were some leaks of memory but I couldn't identify the leak...
I also tried various freeing and Py_DECREF combinations and attempt to reduce the leakage, but with no avail...

Bit of an R shiny novice so bear with me. I am trying to convert some R code I've written into an R shiny app so others can use it more readily. The code utilizes a package called IPDfromKM. The main function of issue is getpoints(), which in R will generate a plot and the user will need to click the max X and max Y coordinates, followed by clicking through the entire KM curve, which extracts the coordinates into a data frame. However, I cannot get this to work in my R shiny app.
There is a [link ](https://biostatistics.mdanderson.org/shinyapps/IPDfromKM/)to the working R shiny app from the creator
This is the getpoints() code:
```
getpoints <- function(f,x1,x2,y1,y2){
## if bitmap
if (typeof(f)=="character")
{ lfname <- tolower(f)
if ((strsplit(lfname,".jpeg")[[1]]==lfname) && (strsplit(lfname,".tiff")[[1]]==lfname) &&
(strsplit(lfname,".bmp")[[1]]==lfname) && (strsplit(lfname,".png")[[1]]==lfname) &&
(strsplit(lfname,".jpg")[[1]]==lfname))
{stop ("This function can only process bitmap images in JPEG, PNG,BMP, or TIFF formate.")}
img <- readbitmap::read.bitmap(f)
} else if (typeof(f)=="double")
{
img <- f
} else {
stop ("Please double check the format of the image file.")
}
## function to read the bitmap and points on x-axis and y-axis
axispoints <- function(img){
op <- par(mar = c(0, 0, 0, 0))
on.exit(par(op))
plot.new()
rasterImage(img, 0, 0, 1, 1)
message("You need to define the points on the x and y axis according to your input x1,x2,y1,y2. \n")
message("Click in the order of left x-axis point (x1), right x-axis point(x2),
lower y-axis point(y1), and upper y-axis point(y2). \n")
x1 <- as.data.frame(locator(n = 1,type = 'p',pch = 4,col = 'blue',lwd = 2))
x2 <- as.data.frame(locator(n = 1,type = 'p',pch = 4,col = 'blue',lwd = 2))
y1 <- as.data.frame(locator(n = 1,type = 'p',pch = 3,col = 'red',lwd = 2))
y2 <- as.data.frame(locator(n = 1,type = 'p',pch = 3,col = 'red',lwd = 2))
ap <- rbind(x1,x2,y1,y2)
return(ap)
}
## function to calibrate the points to the appropriate coordinates
calibrate <- function(ap,data,x1,x2,y1,y2){
x <- ap$x[c(1,2)]
y <- ap$y[c(3,4)]
cx <- lm(formula = c(x1,x2) ~ c(x))$coeff
cy <- lm(formula = c(y1,y2) ~ c(y))$coeff
data$x <- data$x*cx[2]+cx[1]
data$y <- data$y*cy[2]+cy[1]
return(as.data.frame(data))
}
## take the points
ap <- axispoints(img)
message("Mouse click on the K-M curve to take the points of interest. The points will only be labled when you finish all the clicks.")
takepoints <- locator(n=512,type='p',pch=1,col='orange4',lwd=1.2,cex=1.2)
df <- calibrate(ap,takepoints,x1,x2,y1,y2)
par()
return(df)
}
```
I'm a bit at a loss in how to execute this in my main panel. I've tried using plotOutput(), imageOutput(), and calling variations of the below functions, but nothing pops up or seems to work like it does in R studio. Will I need to split out the components of the function into individual steps?
```
createPoints<-reactive({
#Read File
file <- input$file1
ext <- tools::file_ext(file$datapath)
req(file)
validate(need(ext == "png", "Please upload a .png file"))
##should run the function that generates a plot for clicking coordinates and stores them in a data frame
points<-getpoints(file,x1=0, x2=input$Xmax,y1=0, y2=100)
return(points)
})
```
```
output$getPointsPlot<-renderPlot(
createPoints()
)

In GLSL I iterate over a float buffer, that contains the coordinates and a couple properties of elements to render. I was curious about shaders (don't have much experience with them) and wanted to obsessively optimise it. When looking at how it gets compiled (I'm using WebGL+Spector.js), I notice that in the loop where I access the array it clamps the accesses to the size of the buffer.
I understand this is heavily machine dependent, and is done to ensure no out of bounds accesses, but is there not a way to avoid these checks or guarantee to the compiler out of bounds accesses aren't possible (eg. adding a condition to the loop)? I'm mostly curious about the (small) performance impact these operations have (6 `clamp`s, and int + float casts per iteration!)
Any other potential optimisation tips are welcome, I'm very new to this and super interested in it. I thought about maybe passing the data as an array of `vec3`s instead to reduce array accesses to 2/element. Not sure if it would improve it though !
### Original code:
```c
// maxRelevantIndex is a uniform, elementSize is a const = 6, elements is of size 60
for (int i = 0; i < maxRelevantIndex; i += elementSize) {
float x1 = elements[i];
float y1 = elements[i + 1];
float x2 = elements[i + 2];
float y2 = elements[i + 3];
float br = elements[i + 4];
float color = elements[i + 5];
...
}
```
### Decompiled:
```glsl
for (int _uAV = 0;
(_uAV < _uU);
(_uAV += 6)) {
float _uk = _uV[int(clamp(float(_uAV), 0.0, 59.0))];
float _ul = _uV[int(clamp(float((_uAV + 1)), 0.0, 59.0))];
float _um = _uV[int(clamp(float((_uAV + 2)), 0.0, 59.0))];
float _un = _uV[int(clamp(float((_uAV + 3)), 0.0, 59.0))];
float _uAW = _uV[int(clamp(float((_uAV + 4)), 0.0, 59.0))];
float _uAC = _uV[int(clamp(float((_uAV + 5)), 0.0, 59.0))];
...
}

I have a json like
[
{
"url": "https://drive.google.com/file/d/1tO-qVknlH0PLK9CblQsyd568ZiptdKff/view?usp=share_link",
"title": "– Flexibility"
},
{
"url": "https://drive.google.com/open?id=11_sR8X13lmPcvlT3POfMW3044f3wZdra",
"title": "– Pronouns"
}
]
I got it using `curl -Lfs "https://motivatedsisters.com/2019/07/08/arabic-review-sr-rahat-basit/" | rg -o '<li>.*?href="(.*?)".*?</a> (.*?)<\/li>' -r '{"url": "$1", "title": "$2"}' | jq -s '.'`.
I have a command in my machine named `unescape_html`, a python scipt to unescape the html (replace – with appropriate character).
How can I apply this function on each of the titles using `jq`.
For example:
I want to run:
unescape_html "– Flexibility"
unescape_html "– Pronouns"
The expected output is:
[
{
"url": "https://drive.google.com/file/d/1tO-qVknlH0PLK9CblQsyd568ZiptdKff/view?usp=share_link",
"title": "– Flexibility"
},
{
"url": "https://drive.google.com/open?id=11_sR8X13lmPcvlT3POfMW3044f3wZdra",
"title": "– Pronouns"
}
]
**Update 1:**
If `jq` doesn't have that feature, then i am also fine that the command is applied on `rg`.
I mean, can i run `unescape_html` on `$2` on the line:
rg -o '<li>.*?href="(.*?)".*?</a> (.*?)<\/li>' -r '{"url": "$1", "title": "$2"}'
Any other bash approach to solve this problem is also fine. The point is, i need to run `unescape_html` on `title`, so that i get the expected output.
**Update 2:**
The following command:
curl -Lfs "https://motivatedsisters.com/2019/07/08/arabic-review-sr-rahat-basit/" | rg -o '<li>.*?href="(.*?)".*?</a> (.*?)<\/li>' -r '{"url": "$1", "title": "$2"}' | jq -s '.' | jq 'map(.title |= @sh "unescape_html \(.)")'
gives:
[
{
"url": "https://drive.google.com/file/d/1tO-qVknlH0PLK9CblQsyd568ZiptdKff/view?usp=share_link",
"title": "unescape_html '– Flexibility'"
},
{
"url": "https://drive.google.com/open?id=11_sR8X13lmPcvlT3POfMW3044f3wZdra",
"title": "unescape_html '– Pronouns'"
}
]
Just not evaluating the commands.
The following command works:
curl -Lfs "https://motivatedsisters.com/2019/07/08/arabic-review-sr-rahat-basit/" | rg -o '<li>.*?href="(.*?)".*?</a> (.*?)<\/li>' -r '{"url": "$1", "title": "$2"}' | jq -s '.' | jq 'map(.title |= sub("–"; "–"))'
But it only works for `–`. It will not work for other reserved characters. |

Heres a much simpler version of the accepted answer, without using combine
```

}
}
extension SearchManager: MKLocalSearchCompleterDelegate {
func completerDidUpdateResults(_ completer: MKLocalSearchCompleter) {
completions = completer.results
}
func completer(_ completer: MKLocalSearchCompleter, didFailWithError error: Error) {
print("Error: \(error.localizedDescription)")
}
}
```
and heres the SwiftUI view
```

I am receiving a json string of the form
```json
{
"people": [
{
"Freddie": {
"surname": "Mercury",
"city": "London"
}
},
{
"David": {
"surname": "Bowie",
"city": "Berlin"
}
}
]
}
```
with the ultimate goal of recovering them as Proto messages of the kind
```
message People {
optional string name = 1;
optional string surname = 2;
optional string city = 3;
}
message Msg {
repeated People folks = 1;
}
```
What is the best practice - i.e. short of custom adhoc logic of manipulating the keys - to convert the above json string to a string
sich as
```
{
"people": [
{
"name": "Freddie",
"surname": "Mercury",
"city": "London"
},
{
"name": "David",
"surname": "Bowie",
"city": "Berlin"
}
]
}
```
so that the correspondence between the json
and the Proto is one-to-one, and therefore out-of-the-box deserializers could be used?

A **[with expression][1]** produces a ***copy of its operand*** with the specified properties and fields modified.
Starting with C# 10, the LHS operand of a **with** expression can now be - **records**, **structs** or **anonymous** types.
**Records**:
public record Person(string FirstName, string LastName);
public static class Program
{
public static void Main()
{
Person person = new("Nancy", "Davolio");
Console.WriteLine(person);
// output: Person { FirstName = Nancy, LastName = Davolio }
var personCreatedUsingWithExpression = person with { FirstName = "Dave" };
Console.WriteLine(personCreatedUsingWithExpression);
// output: Person { FirstName = Dave, LastName = Davolio }
}
}
**Records containing reference type member**: Only the reference to a member instance is copied when an operand is copied. Both the copy and original operand have access to the same reference-type instance.
> public class ExampleWithReferenceType {
> public record TaggedNumber(int Number, List<string> Tags)
> {
> public string PrintTags() => string.Join(", ", Tags);
> }
>
> public static void Main()
> {
> var original = new TaggedNumber(1, new List<string> { "A", "B" });
>
> var copy = original with { Number = 2 };
> Console.WriteLine($"Tags of {nameof(copy)}: {copy.PrintTags()}");
> // output: Tags of copy: A, B
>
> original.Tags.Add("C");
> Console.WriteLine($"Tags of {nameof(copy)}: {copy.PrintTags()}");
> // output: Tags of copy: A, B, C
> }
> }
**Structs**: Since a `record` in C# is technically a `struct`, it is easier to remember that `with` expression works with `struct`s as well.
public readonly struct Coords
{
public Coords(double x, double y)
{
X = x;
Y = y;
}
public double X { get; init; }
public double Y { get; init; }
public override string ToString() => $"({X}, {Y})";
}
public static void Main()
{
var p1 = new Coords(0, 0);
Console.WriteLine(p1); // output: (0, 0)
var p2 = p1 with { X = 3 };
Console.WriteLine(p2); // output: (3, 0)
var p3 = p1 with { X = 1, Y = 4 };
Console.WriteLine(p3); // output: (1, 4)
}
**Anonymous Types**:
var apple = new { Item = "apples", Price = 1.35 };
var onSale = apple with { Price = 0.79 };

No programming is required. Create a shortcut to your program on the desktop. Right-click it, Properties, Layout tab. Adjust the Width property of the screen buffer and window size.
But you can do it programmatically too, those Windows API functions you found are wrapped by the Console class as well. You first have to make sure that the console buffer is large enough, then you can set the window size to a size that's at least as large as the buffer. For example:
static void Main(string[] args) {
Console.BufferWidth = 100;
Console.SetWindowSize(Console.BufferWidth, 25);
Console.ReadLine();
}

But I want to be able to inject different instances of the preferences object for previews vs the production code so I've abstracted my production object in to a `Preferences` protocol and updated my Environment key's type to:
```swift
protocol Preferences { }
@Observable
final class MyPreferencesObject: Preferences { }
@Observable
final class MyPreviewsObject: Preferences { }
// Environment key
private struct PreferencesKey: EnvironmentKey {
static let defaultValue : Preferences & Observable = MyPreferencesObject()
}
extension EnvironmentValues {
var preferences: Preferences & Observable {
get { self[PreferencesKey.self] }
set { self[PreferencesKey.self] = newValue }
}
}
```
The compiler is happy with this until I go to use `@Bindable` in my code where the compiler explodes with a generic error,
eg:
```swift
@Environment(\.preferences) private var preferences
// ... code
@Bindable var preferences = preferences
```
If I change the environment object back to a conforming type eg:
```swift
@Observable
final class MyPreferencesObject() { }
private struct PreferencesKey: EnvironmentKey {
static let defaultValue : MyPreferencesObject = MyPreferencesObject()
}
extension EnvironmentValues {
var preferences: MyPreferencesObject {
get { self[PreferencesKey.self] }
set { self[PreferencesKey.self] = newValue }
}
}
```
Then `@Bindable` is happy again and things compile.
Specifically the compiler errors with:
> Failed to produce diagnostic for expression; please submit a bug report (Swift.org - Contributing)
On the parent function the @Bindable is inside of
and with a
> Command SwiftCompile failed with a nonzero exit code
In the app target.
Is this a known issue/limitation? Or am I missing something here? |

With input:
```
import re
text = "Of the hundreds of thousands of high school wrestlers, only a small percentage know what it’s like to win a state title. {{Elided}} is part of that percentage. The Richmond junior joined that group by winning… Premium Content is available to subscribers only. Please login here to access content or go here to purchase a subscription."
paywall_keywords = ["login", "subscription", "purchase a subscription", "subscribers"]
```
Form pattern for filter:
```
patt = re.compile('|'.join(['.*' + k for k in paywall_keywords]))
'.*login|.*subscription|.*purchase a subscription|.*subscribers'
```
Split text by sentences:
```
phrases = text.split(sep='.')
['Of the hundreds of thousands of high school wrestlers, only a small percentage know what it’s like to win a state title',
' {{Elided}} is part of that percentage',
' The Richmond junior joined that group by winning… Premium Content is available to subscribers only',
' Please login here to access content or go here to purchase a subscription',
'']
```
*nltk indeed helps splitting by "..." too*
Find hits:
```
found = list(filter(patt.match, phrases))
[' The Richmond junior joined that group by winning… Premium Content is available to subscribers only',
' Please login here to access content or go here to purchase a subscription']
```
Eliminate those and reform the text:
```
'.'.join([p for p in phrases if p not in found])
'Of the hundreds of thousands of high school wrestlers, only a small percentage know what it’s like to win a state title. {{Elided}} is part of that percentage.'
```

Following some suggestions from Microsoft forums, I tried to add the only user I have to the Build Administrator group of project A and also to be safe I added it to project B without success.
I also tried to recreate the project, deployment group without success.
I used this reference link: https://developercommunity.visualstudio.com/t/error-vs800075-when-downloading-artifact-from-anot/1146258 |

However,for initial fen = "8/8/8/4k3/2K4R/8/8/8 w - - 0 1" it doesn't give the optimal result like this one: https://lichess.org/analysis/8/8/8/4k3/2K4R/8/8/8_w_-_-_0_1?color=white
Rather, it gives 27 plies [like this](https://pastebin.com/hZ6AaBZe) while lichess.com link above gives 1000-977==23 plies. Finding the bug will be highly appreciated. |
I am a beginner in C# and cpp, and When I'm trying to build the FiveM launcher from the the [FiveM launcher OpenSource code](https://github.com/citizenfx/fivem) FiveM launcher OpenSource code, I'm getting this error after doing fxd build.

I am trying to make a to do list. MY app take a data successfully.
But when I want to delete a data from the list. it is showing typeerror: passdata.map is not a function. I am just learning react and I can not figure out where the problem is.
N:B: My code is in between two components.
```
`import React, { useState } from "react";
import { OutputData } from "./OutputData";
export const Form = () => {
const [data, setData] = useState("");
const [val, setVal] = useState([]);
const changed = (event) => {
setData(event.target.value);
};
const clicked = () => {
setVal((oldVal) => {
return [...oldVal, data];
});
setData(" ");
};
const del = (id)=>{
setVal((newVal)=>{
return newVal.filter((val,index)=>{
return id !== index;
});
});
setVal("");
}
return (
<div>
<div>
<h1>To Do List</h1>
<input type="text" onChange={changed} />
<button onClick={clicked}>
<span>+</span>
</button>
</div>
<div>
<OutputData passData={val} del={del}></OutputData>
</div>
</div>
);
};
```
My Second Component Here:
```
import React from 'react'
export const OutputData = ({passData,index,del}) => {
return (
<div>
{
passData.map((passData,index)=>{
return(
<div className='lidiv' key={index}>
<li>{passData}</li>
<button onClick={() => del(index)}>Delete</button>
</div>
)
})
}
</div>
)
}
```
I want to know why is this happened & How to solve this problem |

I would consider [this previous answer][1] that you can combine with a mask to hide a portion of the circle:
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-css -->
svg {
width:200px;
transform:rotate(90deg); /* control the rotation here */
}
<!-- language: lang-html -->
<svg viewBox="-3 -3 106 106">
<defs>
<mask id="m" >
<rect x="-3" y="-2" width="100%" height="100%" fill="white"/>
<!-- update the 120 below to increase/decrease the visible part-->
<circle cx="50" cy="50" r="50"
stroke-dasharray="120, 1000"
fill="transparent"
stroke="black"
stroke-width="8"/>
</mask>
</defs>
<!--
The circumference of the circle is 2*PI*R ~ 314.16
if we want N dashed we use d=314.16/N
For N = 20 we have d=15.71
For a gap of 5 we will have "10.71,5" (d - gap,gap)
-->
<circle cx="50" cy="50" r="50"
stroke-dasharray="10.71, 5"
fill="transparent"
stroke="black"
stroke-width="5" mask="url(#m)" />
</svg>
<!-- end snippet -->
A pure CSS solution but with low support actually due to the conic-gradient()
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-css -->
.box {
--d:4deg; /* distance between dashes */
--n:30; /* number of dashes */
--c:#000; /* color of dashes */
--b:2px; /* control the thickness of border*/
--m:60deg; /* the masked part */
--r:0deg; /* rotation */
width: 180px;
display:inline-block;
aspect-ratio: 1;
border-radius:50%;
transform:rotate(var(--r));
background:
repeating-conic-gradient(
var(--c) 0 calc(360deg/var(--n) - var(--d)),
transparent 0 calc(360deg/var(--n)));
mask:
conic-gradient(#000 var(--m),#0000 0) intersect,
radial-gradient(farthest-side,#0000 calc(100% - var(--b) - 1px),#000 calc(100% - var(--b)) calc(100% - 1px),#0000);
}
body {
background:linear-gradient(to right,yellow,pink);
}
<!-- language: lang-html -->
<div class="box"></div>
<div class="box" style="--n:20;--b:5px;width:150px;--c:blue;--m:20deg"></div>
<div class="box" style="--n:8;--d:20deg;--b:10px;width:130px;--c:red;--m:180deg"></div>
<div class="box" style="--n:18;--d:12deg;--b:8px;width:100px;--c:green;--r:90deg"></div>
<div class="box" style="--n:10;--d:20deg;--b:3px;width:100px;--c:purple;--r:120deg;--m:120deg"></div>
