| Increase values from vector for each call Posted: 04 Jan 2022 05:05 AM PST I want to use a function for a vector multiple times and for each call to increment the vector's value. How could I do it ? #include <iostream> #include <vector> using namespace std; struct A { void pri(std::vector<int> a) { std::cout<<"0: " << a[0] << std::endl; std::cout<<"1: " << a[1] << std::endl; } void priUse(std::vector<int> a) { pri(a); **pri(a + 1);** // to work this } }; int main() { std::vector<int> a = {1, 2}; A aa; aa.priUse(a); return 0; }

| Nuxt CDN: How to host JS files? Posted: 04 Jan 2022 05:05 AM PST Nuxt has a default configuration for CDN. You just have to do: // nuxt.config.js module.exports = { //... build: { publicPath: "https://you-cdn-url.com/_nuxt/" } }
But when I go to my console, the application just gets images from the CDN. I was hoping it would also load CSS and JS files. Can I make it work? (The Nuxt app is SSR) |
| Java - compare LocalDates with 2 and 4 digit years Posted: 04 Jan 2022 05:05 AM PST I am trying to compare two LocalDate variables. One is created by me by hand, so to say, and the other I obtain it through running a Spring JPA query on a Oracle db. If I try to print the one from Oracle db it returns "0022-01-31" while my "by-hand" LocalDate comes out as "2022-01-31". Now, as I understand, the formatting should not matter when comparing the dates themselves. Still, when I try to check that the two dates are equal, I get false. Here is my code: LocalDate lastDayOfTheMonth = LocalDate.now().with(TemporalAdjusters.lastDayOfMonth()); List<MyEntity> myEntityList= pPassPpCardRepository.findAll(); LocalDate expDate = myEntity.get(0).getExpDatePP(); System.out.println("LocalDate lastDayOfTheMonth: " + lastDayOfTheMonth.toString()); System.out.println("myEntityList.get(0).getExpDatePP().toString(): " + myEntityList.get(0).getExpDatePP().toString()); System.out.println("EQUALS attempt1: " + lastDayOfTheMonth.isEqual(expDate)); System.out.println("EQUALS attempt2: " + (lastDayOfTheMonth.compareTo(expDate) == 0));
Console : LocalDate lastDayOfTheMonth: 2022-01-31 myEntityList.get(0).getExpDatePP().toString(): 0022-01-31 EQUALS attempt1: false EQUALS attempt2: false
Why is that ? What am I doing wrong ? |
| ngrx component store select returns anonymousSubject instead of Observable Posted: 04 Jan 2022 05:05 AM PST I am using the ngrx component store to get search results from the backend. However, I am unable to get a single value of the state, but instead I get an anonymousSubject. This anonymousSubject has the needed data but it is nested very deep in the object. When I iterate over the returned observable in the html, I can get the right values, but now I need just a specific value (state.result[0]) but I cant do this. Could someone clarify how I can acces a single value from the anonymousSubject? Thanks in advance! Component.store export interface SearchResultState { result: Array<any>; } const defaultState: SearchResultState = { result: [] }; @Injectable() export class SearchStore extends ComponentStore<SearchResultState> { constructor( private readonly _http: HttpClient, private readonly _notificationHandler: NotificationHandlerService ) { super(defaultState); } readonly loadSearchResult = this.effect((trigger$: Observable<{ query: string; apiLinks: Array<string> }>) => trigger$.pipe( debounceTime(200), switchMap((action) => { if(!action.query.length) { return of(SearchActions.searchSuccess({result: {}})); } const headers: any = { 'Content-Type': 'application/x-www-form-urlencoded', Accept: 'application/json', }; const httpOptions: { headers: HttpHeaders } = {headers: new HttpHeaders(headers)}; const apiCalls = []; for (const apiLink of action.apiLinks) { apiCalls.push(this._http.get(`${API_URL}${apiLink}${action.query}`, httpOptions).pipe( map((resp: any) => resp), )); } return forkJoin(apiCalls).pipe( map((result) => { console.log(result); //prints the right result return this.setSearchResult({result}); }), catchError(async error => { this._notificationHandler.showError(); return SearchActions.searchFailed({error}); }) ); }) ) ); readonly setSearchResult = this.updater((state, result: any) => ({...state, result})); readonly searchResult$: Observable<Array<any>> = this.select(state => { console.log( 'state', state); //prints nothing unless used in the html return state.result; });
Component.ts (partly) public _searchResult$ = this.searchStore.searchResult$; public search($event: string): void { this.searchStore.loadSearchResult({query: $event, apiLinks: this.apiLinks}); console.log(this._searchResult$); //prints the anonymousObject this.searchResults.emit(this._searchResult$); }

| Store JWT tokens in cookies with django-rest-framework-social-oauth2 library Posted: 04 Jan 2022 05:05 AM PST I wanted to securely store my JWT token. Up until now, I have used local storage, but I have read that using local storage is not secure. Hence, I wanted to start using HttpOnly cookies to store my JWT tokens. I was going to use CSRF protection inbuilt into Django to mitigate the security issues with cookies. However, I can't figure out how to use cookies with the Django-rest-framework-social-oauth2 library. There doesn't need to be any other library that has social auth and JWT auth. So my first question, is there a secure storage method that doesn't need cookies. If not, how does use django-rest-framework-social-oauth2 library with cookies? |
| performance of Typed arrays vs Non typed arrays in Javascript Posted: 04 Jan 2022 05:05 AM PST Learning about typed arrays, I read typed arrays normally should be more efficient/performant than non-typed ones. I run this simple test: const a = [1,2,3,"4"] const b = new Uint8Array([1,2,3,4]) const compare = (arr) => { for (let i = 0; i<4; i++) arr[i] } let run=0 const init = performance.now() while(run<10e7){ compare(b) run++ } const finish = performance.now() console.log(finish-init)
array contains mixed string and number types. But maybe I am not getting some idea here... Should those be expected to differ more? Example? |
| how to make the picture still at same resolution but in small in file Posted: 04 Jan 2022 05:05 AM PST i read some of post that tell how to not resize the picture, they say if i use png it got no effect when i send it to firebase,but when i send to firebase the picture is blurry, this is my code @Override protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) { super.onActivityResult (requestCode, resultCode, data); if(requestCode == 100) { Bitmap bitmap = (Bitmap) data.getExtras ( ).get ("data"); ByteArrayOutputStream bytes = new ByteArrayOutputStream ( ); bitmap.compress (Bitmap.CompressFormat.PNG, 100, bytes); String path = MediaStore.Images.Media.insertImage (getApplicationContext ( ).getContentResolver ( ), bitmap, String.valueOf (UUID.randomUUID()), null); imageUri3 = Uri.parse (path); imageView.setImageURI (imageUri3); Log.e("Original dimensions", bitmap.getWidth()+" "+bitmap.getHeight()); } }
and this is my log when i try to check the resolution 
and this is the image result, the i mage became so small when i open it on web 
sorry if i might send a dup question, just tell me the answer and i will delete the question directly if it works :) |

| Generic method (bounded type) vs inheritance Posted: 04 Jan 2022 05:05 AM PST I have a typical question what is better and I think as always the answer is it depends, but I'd like to clarify it anyway. So there are two methods: public static <A extends Animal, F extends Food> void feed(A animal, F food) { animal.setFood(food); } public static void feed(Animal animal, Food food) { animal.setFood(food); }
And the logic: Cat cat = new Cat(); // Cat is a child of Animal Dog dog = new Dog(); // Dog is a child of Animal Pork pork = new Pork(); // Pork is a child of Food pork.setName("Whiskas"); Beef beef = new Beef(); // Beef is a child of Food beef.setName("Pedigree"); AnimalService.feed(cat, beef); AnimalService.feed(dog, pork); cat.eat(); // prints I'm eating Pedigree dog.eat(); // prints I'm eating Whiskas
I understand that there is a conflict of method signatures due to the type erasure, so my question is not "Why I can't have these two methods in the same time?", but rather "Which method would you choose?". |
| Create Table in a Loop inside Stored Procedure Oracle SQL Posted: 04 Jan 2022 05:05 AM PST I am attempting to create a Oracle stored procedure which creates partitioned tables based off of a table containing the table names and the column to be partitioned with. A separate PL/SQL block iterates through the table and calls the procedure with the table name and the column name. Procedure: create or replace PROCEDURE exec_multiple_table_create ( table_name IN VARCHAR2, column_name IN VARCHAR2 ) IS stmt VARCHAR2(5000); tablename VARCHAR2(50); columnname VARCHAR2(50); BEGIN tablename := table_name; columnname := column_name; -- DBMS_OUTPUT.PUT_LINE(tablename); -- DBMS_OUTPUT.PUT_LINE(columnname); stmt := 'create table ' || TABLENAME || '_temp as (select * from ' || COLUMNNAME || ' where 1=2)'; EXECUTE IMMEDIATE stmt USING IN table_name, column_name; stmt := 'alter table ' || tablename || '_temp modify partition by range(' || columnname || ') (PARTITION observations_past VALUES LESS THAN (TO_DATE(''20000101'',''YYYYMMDD'')), PARTITION observations_CY_2000 VALUES LESS THAN (TO_DATE(''20010101'',''YYYYMMDD'')), PARTITION observations_CY_2001 VALUES LESS THAN (TO_DATE(''20020101'',''YYYYMMDD'')), PARTITION observations_CY_2002 VALUES LESS THAN (TO_DATE(''20030101'',''YYYYMMDD'')), PARTITION observations_CY_2003 VALUES LESS THAN (TO_DATE(''20040101'',''YYYYMMDD'')), PARTITION observations_CY_2004 VALUES LESS THAN (TO_DATE(''20050101'',''YYYYMMDD'')), PARTITION observations_CY_2005 VALUES LESS THAN (TO_DATE(''20060101'',''YYYYMMDD'')), PARTITION observations_CY_2006 VALUES LESS THAN (TO_DATE(''20070101'',''YYYYMMDD'')), PARTITION observations_CY_2007 VALUES LESS THAN (TO_DATE(''20080101'',''YYYYMMDD'')), PARTITION observations_CY_2008 VALUES LESS THAN (TO_DATE(''20090101'',''YYYYMMDD'')), PARTITION observations_CY_2009 VALUES LESS THAN (TO_DATE(''20100101'',''YYYYMMDD'')), PARTITION observations_CY_2010 VALUES LESS THAN (TO_DATE(''20110101'',''YYYYMMDD'')), PARTITION observations_FUTURE VALUES LESS THAN ( MAXVALUE ) )'; EXECUTE IMMEDIATE stmt USING IN table_name, column_name; RETURN; END exec_multiple_table_create;
The PL/SQL block which is using the stored proc is: BEGIN FOR partition_item IN ( SELECT table_name, partition_column FROM partition_table ) LOOP exec_multiple_table_create(partition_item.table_name, partition_item.partition_column); END LOOP; END;
Now, when I try executing the thing, this is what I am seeing: Error report - ORA-06550: line 9, column 9: PLS-00905: object SCG_MYACCT_CUSTOMPC.EXEC_MULTIPLE_TABLE_CREATE is invalid ORA-06550: line 9, column 9: PL/SQL: Statement ignored 06550. 00000 - "line %s, column %s:\n%s" *Cause: Usually a PL/SQL compilation error. *Action:
I have a feeling that I am missing something. Please let me know what it is. The table containing the reference data exists and contains data. I have tried refreshing the table, rewriting and modifying the pl/sql block & the procedure code. Nothing seems to be working. Thanks in advance. UPDATE 1: There was a glitch in the stored procedure where I needed to refer to the tablename rather than the columnname in the code above. However, I am getting a different error right now. Error report - ORA-06546: DDL statement is executed in an illegal context ORA-06512: at "SCG_MYACCT_CUSTOMPC.EXEC_MULTIPLE_TABLE_CREATE", line 18 ORA-06512: at line 9 ORA-06512: at line 9 06546. 00000 - "DDL statement is executed in an illegal context" *Cause: DDL statement is executed dynamically in illegal PL/SQL context. - Dynamic OPEN cursor for a DDL in PL/SQL - Bind variable's used in USING clause to EXECUTE IMMEDIATE a DDL - Define variable's used in INTO clause to EXECUTE IMMEDIATE a DDL *Action: Use EXECUTE IMMEDIATE without USING and INTO clauses to execute the DDL statement.
Please help me out with this as well. UPDATE 2: I removed the USING part of the EXECUTE IMMEDIATE statement. That seemed to take care of the error I posted. Getting a different error with versions now: Error starting at line : 1 in command - BEGIN FOR partition_item IN ( SELECT table_name, partition_column FROM partition_table ) LOOP exec_multiple_table_create(partition_item.table_name, partition_item.partition_column); END LOOP; END; Error report - ORA-00406: COMPATIBLE parameter needs to be 12.2.0.0.0 or greater ORA-00722: Feature "Conversion into partitioned table" ORA-06512: at "SCG_MYACCT_CUSTOMPC.EXEC_MULTIPLE_TABLE_CREATE", line 37 ORA-06512: at line 9 ORA-06512: at line 9 00406. 00000 - "COMPATIBLE parameter needs to be %s or greater" *Cause: The COMPATIBLE initialization parameter is not high enough to allow the operation.

OnlineView.vue <template> <div> <h1>Router app</h1> </div> </template> <script> import { reactive, toRefs } from 'vue' export default { setup () { const state = reactive({ count: 0, }) return { ...toRefs(state), } } } </script>
master.blade.php <main id="app"> @yield('content') </main>

| How is HttpServletResponse entangled with the fetch API when making a GET request for a BLOB? Posted: 04 Jan 2022 05:06 AM PST Using Spring Boot, I am trying to implement a REST controller, which can handle a GET request asking to return a BLOB object from my database. Googling around a little bit, and putting pieces together, I have created the following code snippet: @GetMapping("student/pic/studentId") public void getProfilePicture(@PathVariable Long studentId, HttpServletResponse response) throws IOException { Optional<ProfilePicture> profilePicture; profilePicture = profilePictureService.getProfilePictureByStudentId(studentId); if (profilePicture.isPresent()) { ServletOutputStream outputStream = response.getOutputStream(); outputStream.write(profilePicture.get().getPicture()); outputStream.close(); } }
I am sending the GET request using VanillaJS and the fetch-API: async function downloadPicture(profilePic, studentId) { const url = "http://localhost:8080/student/pic/" + studentId; const response = await fetch(url); const responseBlob = await response.blob(); if (responseBlob.size > 0) { profilePic.src = URL.createObjectURL(responseBlob); } }
Somehow, this works. That's great, but now I would like to understand the usage of HttpServletResponse in this context, which I am not familiar with. It seems to me that the fetch-API makes use of HttpServletResponse (maybe even creates it), since I am not creating this object or do anything with it. What is very strange to me is that the return-type of my controller method getProfilePicture() is void, and still I am sending a response, which is most definitely not void. Also, if the profilePicture was not found in my database, for example due to a non-existing studentId being passed, my controller-method does not do anything. But still, I am getting a response code of 200. That's why I have added the responseBlob.size > 0 part in my Javascript to check for a positive response. Can someone explain this magic to me, please? |
| Write splunk query to fetch the number of working days greater than zero Posted: 04 Jan 2022 05:06 AM PST I am trying to write a splunk query where I need to fetch the user details with the number of working days if it is greater than zero. For example I have the below data I, [2022-01-04T01:32:10.165065 #21461] INFO -- : fetched user details for user_id: 5612 with working_days: 0 I, [2021-01-04T01:32:10.165065 #21461] INFO -- : fetched user details for user_id: 5619 with working_days: 10 I, [2021-02-04T01:28:10.165065 #21461] INFO -- : fetched user details for user_id: 8901 with working_days: 0 I, [2021-03-04T01:18:10.165065 #21461] INFO -- : fetched user details for user_id: 306561 with working_days: 35

| How to add a second example app to a Flutter plugin project? Posted: 04 Jan 2022 05:05 AM PST When creating a plugin project in Flutter, an example app, that is using the plugin, is added in a subfolder of the plugin project. What needs to be done to add a second "example" app to the plugin folder? So far I have: Copied and renamed the example folder to (let's call it) app2. Adjusted the package names at the android manifest files of app2. Renamed pluginrootfolder/app2/pluginname_example.iml to pluginrootfolder/app2/pluginname_app2.iml (to reflect the name of the second app). In the .iml file of the plugin project (the root folder): Copied and adjusted the exclude folder directive to reflect app2 <excludeFolder url="file://$MODULE_DIR$/app2/.dart_tool" /> <excludeFolder url="file://$MODULE_DIR$/app2/.pub" /> <excludeFolder url="file://$MODULE_DIR$/app2/build" />
Run Flutter clean and Flutter pub get in both the plugins root directory and app2's directory. Problem now is that app2 causes 1k+ Target of URI doesn't exist: error messages - from packages (like provider and json_annotation) to classes in the plugin's root project. Do you have any ideas what's wrong here or how to fix it? |

| How can I dynamically resize an SVG rect based on text width? Posted: 04 Jan 2022 05:05 AM PST In an SVG graph I create node elements consisting of a rectangle and some text. The amount of text can differ significantly, hence I'd like to set the width of the rect based on the width of the text. Here's the creation of the rectangles with D3.js (using fixed width and height values): var rects = nodeEnter.append("rect") .attr("width", rectW) .attr("height", rectH);
followed by the text element: var nodeText = nodeEnter.append("text") .attr("class", "node-text") .attr("y", rectH / 2) .attr("dy", ".35em") .text(function (d) { return d.data.name; }); nodeText // The bounding box is valid not before the node addition happened actually. .attr("x", function (d) { return (rectW - this.getBBox().width) / 2; });
As you can see, currently I center the text in the available space. Then I tried to set the widths of the rects based on their text, but I never get both, the rect element and the text HTML element (for getBBox()) at the same time. Here's one of my attempts: rects.attr("width", d => this.getBBox().width + 20 );
but obviously this is wrong as it refers to rects not the text. What's the correct approach here? |

| Docker Swarm Service - force update of latest image already running Posted: 04 Jan 2022 05:06 AM PST environment - docker 1.12
- clusted on Ubuntu 16.04
Is there a way to force a rolling update to a docker swarm service already running if the service update is not changing any parameters but the docker hub image has been updated? Example: I deployed service: docker service create --replicas 1 --name servicename --publish 80:80 username/imagename:latest
My build process has updated the latest image on docker hub now I want to pull the latest again. I have tried running: docker service update --image username/imagename:latest servicename
When I follow this process, docker does not pull the latest, I guess it assumes that since I wanted latest and docker already pulled an image:latest then there is nothing to do. The only work around I have is to remove the service servicename and redeploy. |
