Positioning agent randomly within GIS space

           No comments   

I am looking to randomly position a fixed number of 'People' agents into my GIS space with regions. I currently have a table with a column for region and have identically named GIS regions in my GIS map.
Each 'Person' has a parameter 'region' which into which I map the value of the 'region' column in my table to. I then need to find some way to set the position of the agent to a random point inside the assigned region.


I have tried:
GISRegion myRegion = main.map.searchFirstRegion(region);
Point pt = myRegion.randomPointInside();
setXYZ( pt.x, pt.y, pt.z );



in the "On startup" field for my Person Agent but it seems that main.map.searchFirstRegion(region); does not do a good job of getting the correct region, as agents are distributed in places where there is no region (i.e in the sea):
Image


Ideally, I would like to use void setLocation(region) but setLocation takes in a Point or INode variable whereas the 'region' parameter is a string. Is there a way to search the list of regions by name for the matching region and return that region?
Thanks!

python valueerror : too many values to unpack

           No comments   

I am a python beginner . I was trying to run this code :

def main():
print ( " This program computes the average of two exam scores . ")
score1,score2 = input ("Enter two scores separated by a comma:")
average = (score1 + score2)/2.0
print ("The average of the score is : " , average )




when I summon the main() I got this ValueError :

Suppress default message of assert_eq! when custom message provided?

           No comments   

To my surprise, when I supply a custom message, it seems that assert_eq!'s default message is also printed out regardless.


Here I'm comparing some very long strs. So it is preferable not to clutter up the console but instead take a limited slice of each.
let left = tds.get_bulk_post_str();
let error_msg = format!("Bulk text is not what is expected: get_bulk_post_str() starts\n{}...\n\nExpected text starts\n{}...\n",
&left[0..20], &expected_bulk_text[0..20]);
// assert_eq! not used because assert_eq! apparently does not suppress its default message even when you supply a custom message!
// ... and in this case the default message is far too long.
// assert_eq!(left, expected_bulk_text, "{}", error_msg);

// instead, I think I'm forced to do something like this:
if left != expected_bulk_text {
panic!("{}", error_msg)
}



... is there any way of suppressing the default message?


If not, this seems a strange design choice, unlike any other language I know. Is it deliberate?


PS I'm aware the first 20 chars of each string might be identical. Obviously if I really wanted to go to town on this I'd have to examine both strings to find out the first case of difference, and just print corresponding slices from the middle.

Bidimensional splines, strictly increasing in one argument

           No comments   

I am working in R. I want to specify flexibly a function q(X,Y) where q is strictly increasing with respect to X (but not necessarily with respect to Y).
I want to use bidimensional splines but I don't know how to do (how to impose the monotonicity constraint in 2D).
So far, my method is to select several values of Y, and for each values of Y, I compute a monotone splines with respect to X. And then I interpolate to create the whole function q. But I wonder if it was possible to do all this in 1 step?

* Have tried multiple combinations of the security chain as suggested on several similar threads

* Added a few more log statements in security configuration code to capture these events and help understand how the new flow works

* DEBUG level log statements added inside the RestAuthenticationProvider.authenticate() are not showing up in the logs, indicating it is not getting invoked, and the flow is breaking before reaching that point.






However I suspect that the configured AuthenticationProvider (tried using authenticationProvider(..) earlier, but that did not work either) and AuthenticationManager are not getting plugged in the chain for some reason. Need help from the community in guiding me to set this up correctly. Thank you.

Implementing an equation involving integrals as a filter

           No comments   

This is a question that possibly borders on the intersection of the general usage of MATLAB and/or signal processing. Thought I would first ask the question in a MATLAB forum before trying signal processing.



So our lecturer read out his notes/paper and said the equation







could be implemented as a filter.



At first, it seemed difficult to follow the idea but when realizing that integration is same as finding areas under the curve which seems similar to applying a low pass filter so that only the portion of the signal under the threshold is allowed to pass through, it made a bit of sense. But how - meaning to say which function - can I use to implement the above equation? Do I need three filters or can I use just one? How do I use the terms preceding the integrals in the filter?



Thanks in advance

TypeScript Type on constructor to reference itself in extended class

This works but I was wondering if there is a better way of getting the constructor to know we want a UserEntity aka typeof this
class BaseEntity {
constructor(data: ) {
Object.assign(this, data);
}
}

class UserEntity extends BaseEntity {
name: string;
}

user = new UserEntity({name: 'Bar'});

How to I add the sum of 2 dice throw continuously in JS?

           No comments   

I'm doing a school project of a dice game, the player select a number between 6-9 and afterwards throw two dices. If the dices show the chosen number, its game over. But i cant get the sum to add upp after each throw, it just shows each specific throws sum.


Also, how do i get the program to understand that it's game over when the dices shows the "knockout" number?


let knockoutSiffra = 0;

const dices = document.querySelectorAll('.dice');
console.log(dices);

dices.forEach(bt =>{
bt.addEventListener('click', (e) =>{
knockoutSiffra = e.target.innerHTML;
console.log(knockoutSiffra)
})
})

document.getElementById('go')
.addEventListener('click', () => {

if(knockoutSiffra != 0){
choose.style.display = 'none'
play.style.display = 'block'
console.log('kör')
}

else{
console.log('välj ett nummer')

}

const showNumber = document.getElementById('showNumber');
showNumber.innerText = 'Ditt valda nummer är:' + " " + knockoutSiffra

})

// Slide 3

let lost = document.querySelector('.lost')
lost.style.display = 'none';

const dice1 = document.querySelector('.dice1');
const dice2 = document.querySelector('.dice2');
const result = document.querySelector('.dice-result');
const game = document.querySelector('.game');

let score = 0;

game.addEventListener('click', () => {
let d1 = GetRandomDice ();
let d2 = GetRandomDice ();

dice1.src = `Dice img/Dice-${d1}.png`;
dice2.src = `Dice img/Dice-${d2}.png`;

let sum = d1 + d2;
result.innerText = 'Antal poäng:' + " " + sum;

function GetRandomDice(){
return Math.ceil(Math.random() * 6);

}

})

This is just the last part of the HTML

Array2, with num value:

ID: 2, NUM: 200
ID: 4, NUM: 400




I want the output like: (adding zero if no record in array2)

ID: 1, NUM: 0
ID: 2, NUM: 200
ID: 3, NUM: 0
ID: 4, NUM: 400
ID: 5, NUM: 0




I am new to PHP, tried array_diff and array_intersect but not find the clue, could you please let me know how can I do that?



Thanks.

Using UPDATE ... SET arr[idx] = ... to aggregate rows into arrays

           No comments   

I currently have a database schema like the following table:
CREATE TABLE Measures(
expId SERIAL,
iteration INT NOT NULL,
value float4 NOT NULL,
PRIMARY KEY(expId, iteration)
);




So, a table of various measurements, repeated for n iterations.
Though, because we have more data than originally expected, I want to move to a new table layout that instead uses an array column, which overall gives better performance (already tested and benchmarked):
CREATE TABLE TmpMeasures(
expId SERIAL PRIMARY KEY,
values float4[] NOT NULL
);



My problem now is how to get the old data into the new format.
In the simplest case, the data may look something like this:
INSERT INTO Measures (expId, iteration, value)
VALUES
(1, 1, 1.1),
(1, 2, 2.1),
(1, 3, 3.1),
(2, 1, 1.2),
(3, 1, 1.3);



And conversion could be done with a two step process, roughly like this, to first create the array for an experiment, and then populate the iteration values:
INSERT INTO TmpMeasures(expId, values)
SELECT expId, '{}'::float4[]
FROM Measures
ON CONFLICT DO NOTHING;

UPDATE TmpMeasures tm
SET values[iteration] = m.value
FROM Measures m WHERE tm.expId = m.expId;



Though, my problem now is that the UPDATE actually only ever seems to take the first iteration, i.e., iteration = 1.
I am not quite understanding why that is the case.


I suspect, alternative approaches to values[iteration] would try to group by expId, and order by iteration and aggregate that into an array.


Unfortunately, the data isn't perfect, but iterations should line up.


So, the following seems to work, but it's extremely slow, and I don't quite understand why it's needed in the first place.
DO
$do$
BEGIN
FOR i IN 1..(SELECT max(iteration) FROM Measures m) LOOP
UPDATE TmpMeasures tm
SET values[i] = m.value
FROM Measures m
WHERE
tm.expId = m.expId AND
m.iteration=i;
END LOOP;
END
$do$;



Why does the "normal" update statement not suffice?

How to Create a New Table from JSONB_ARRAY_ELEMENTS and JSONB_OBJECT_KEYS in Postgresql?

           No comments   

I am using the http extension in Postgresql, making a request, and getting a list of jsonb [{keys, values}] in a single column 'details' as a response.


It seems like there should be an easy way to create a new table from the keys and values.


Here is the request:
WITH sport_markets_api AS (
SELECT ((CONTENT::jsonb ->> 'data')::jsonb ->> 'sportMarkets')::jsonb AS details
FROM http_post(
'
https://api.thegraph.com/subgraphs/name/', /> '{"query": "{sportMarkets(first:2,skip:0,orderBy:timestamp,orderDirection:desc){id,timestamp,address,gameId,maturityDate,tags,isOpen,isResolved,isCanceled,finalResult,homeTeam,awayTeam }}"}'::text,
'application/json'))



I tried:

SELECT
jsonb_array_elements(details) ->> jsonb_object_keys(jsonb_array_elements(details))
FROM sport_markets_api




and was expecting a table with columns based on the keys.

Is there a way to set Horizon's timeout on a job class ?

           No comments   

I'm refactoring a class that records a (predefined length of) an audio stream using Symfony process and an OS executable file.

The way it used to work was the job was sent on a regular redis queue, and timeout would be set on the symfony process, effectively making the job run for the time it needed.

Now we want to send the job on a Horizon queue. The timeout is still set on the process, but Horizon's config has its own timeout value in the config. The problem is that the length of the recording will vary from case to case, with an average being 60 minutes, but we do have cases doing for multiple hours.

I could set it up to a very (very) long timeout, but I find it counterintuitive. Isn't there a way that I could specify the value for timeout on a job ? Otherwise, is setting a humongously long timeout the only logical way to do this ? submitted by /u/CouldHaveBeenAPun

I wanted to label the rows so that it groups the same display ID that are right next to each other but would not group them if there's something else in btw.
The desired outcome should be the following:






websit_id

updated_at

display_id

group_label







1222

apple

Async Initializers Swift MVVM not working

           No comments   

Hi cann someone help me I really have trouble to get these inits to work. Due to the Tasks im always getting yelled at by xcode the not all properties are initialized:
import Foundation
import FirebaseFirestore

class ChatViewModel: ObservableObject {

@Published var chat: ChatModel
@Published var opposingUser: User

init(oppUser: User) {
self.opposingUser = oppUser
Task {
if let fetchedChat = try? await fetchChat(oppUser: oppUser) {
self.chat = fetchedChat
}
}
}

init(chat: ChatModel) {
self.chat = chat
Task {
if let fetchedUser = try? await getOpposingUser(chat: chat) {
self.opposingUser = fetchedUser
}
}
}

@MainActor
func fetchChat(oppUser: User) async throws -> ChatModel? {
do {
let documents = try await Firestore.firestore()
.collection("conversations")
.whereField("users", arrayContains: UserService.shared.currentUser?.id ?? "error")
.whereField("users", arrayContains: oppUser.id)
.getDocuments()

for document in documents.documents {
guard let chatData = try? document.data(as: ChatModel.self) else {
print("[DEBUG fetchChat(oppUser: User)]: Error while converting Firebase Document to ChatModel ")
return nil
}

return chatData
}
} catch {
print("[DEBUG fetchChat(oppUser: User)]: \(error)")
throw error // Re-throw the error so it can be handled by the caller if needed
}
return nil
}

@MainActor
func getOpposingUser(chat: ChatModel) async throws -> User? {
do {
let opposingUid: String
if chat.users[0] == UserService.shared.currentUser?.id {
opposingUid = chat.users[1]
} else {
opposingUid = chat.users[0]
}

let document = try await Firestore
.firestore()
.collection("users")
.document(opposingUid)
.getDocument()

guard let opposingUserDoc = try? document.data(as: User.self) else {
// Handle the case where conversion to User fails
print("[DEBUG (getOpposingUser(chat: chatModel)]: Error while converting Firebase-Document to User ")
return nil
}

return opposingUserDoc

} catch {
print("[DEBUG (getOpposingUser(chat: chatModel)]: \(error) ")
throw error
}
return nil
}
}



I tried to "pre initilize" the variables with something like self.chat = ChatModel() but due to the nature of my Cahtmodel I can't init it without properties.

How to type two variables that are correlated in TypeScript?

           No comments   

I have a structure ComboChartSpec with primary and secondary fields. I'm defining a util function to process this ComboChartSpec.


If I define it in this way, it works
function process1() {
const yAxisType = 'primary';
const otherYAxisType = 'secondary';
return {
[yAxisType]: foo,
[otherYAxisType]: bar
}
}
function process2() {
const yAxisType = 'secondary';
const otherYAxisType = 'primary';
return {
[yAxisType]: foo,
[otherYAxisType]: bar
}
}



I want to merge these two functions. But I kept getting TS errors. How can I resolve it? Thanks!
function process(yAxisType: 'primary' | 'secondary') {
const otherYAxisType = yAxisType === 'primary' ? 'secondary' : 'primary';
return {
[yAxisType]: foo,
[otherYAxisType]: bar
}
}

Type '{ [x: string]: { fields: never[]; } | { type: "quantitative"; }; scale: { type: "quantitative"; }; }' is not assignable to type 'ComboChartAxisEncoding'.
Type '{ [x: string]: { fields: never[]; } | { type: "quantitative"; }; scale: { type: "quantitative"; }; }' is not assignable to type 'ComboChartSingleAxisEncoding'.
Type '{ [x: string]: { fields: never[]; } | { type: "quantitative"; }; scale: { type: "quantitative"; }; }' is missing the following properties from type '{ primary: ComboChartSingleAxisSectionEncoding; secondary: ComboChartSingleAxisSectionEncoding; scale: QuantitativeScale; }': primary, secondaryts(2322)
index.ts(85, 3): The expected type comes from property 'y' which is declared here on type 'ComboChartEncodingMap'



See Minimal repro on TS playground 👈
export type ComboChartAxisEncoding = ComboChartSingleAxisEncoding | ComboChartDualAxisEncoding;

export type ComboChartSingleAxisEncoding = {
primary: ComboChartSingleAxisSectionEncoding;
secondary: ComboChartSingleAxisSectionEncoding;
scale: 'quantitative';
};
export type ComboChartSingleAxisSectionEncoding = {
fields: number[];
};
export type ComboChartDualAxisEncoding = {
primary: ComboChartDualAxisSectionEncoding;
secondary: ComboChartDualAxisSectionEncoding;
};
export type ComboChartDualAxisSectionEncoding = {
fields: number[];
scale: 'quantitative';
};

function process1(): ComboChartAxisEncoding {
const yAxisType: 'primary' | 'secondary' = 'primary';
const otherYAxisType: 'primary' | 'secondary' = 'secondary';

return { // this works
[yAxisType]: { fields: [] },
[otherYAxisType]: { fields: [] },
scale: 'quantitative',
};
}
function process2(yAxisType: T): ComboChartAxisEncoding {
const otherYAxisType = (yAxisType === 'primary' ? 'secondary' : 'secondary') as (T extends 'primary' ? 'secondary' : 'primary');

// this doesn't work. Note that in my case this function wraps lots of test cases and each of them has this structure.
// So, if I don't have to change the structure of the JS objects, and just need to change the types, it would be better.
return {
[yAxisType]: { fields: [] },
[otherYAxisType]: { fields: [] },
scale: 'quantitative',
};
}
