| Spring Boot, NamedParameterJdbcTemplate query and get generated PID from the postgres database Posted: 02 Oct 2021 07:53 AM PDT I'm using postgres and need to get the process identifier from postgres. Every running query in postgres has it's own PID which we can get via -> pg_stat_activity. SELECT * FROM pg_catalog.pg_stat_activity; This returns pid, which we can use to stop executing queries in database using SELECT pg_terminate_backend(); The application is Spring Boot / Java and I make some huge queries using NamedParameterJdbcTemplate. They can take long time and in some cases I need to terminate executing queries. The question is how can I get the PID from the generated sql query ?  |

| Can someone help me with this Posted: 02 Oct 2021 07:53 AM PDT David Phillips is an American civil engineer and professor at the University of California (Davis, USA). He is best known as The Pudding Guy for accumulating many frequent-flyer miles by taking advantage of a promotion by Healthy Choice in 1999. Phillips was pushing his shopping cart down the frozen-food aisle of his local supermarket when a promotion on a Healthy Choice frozen entree caught his eye. The company was offering frequent-flyer miles to customers who bought its products and submitted the UPCs back to the company. The details of the promotion included a bonus if the UPCs were mailed during the month of May 1999 (the mileage earned would double from 500 miles to 1000 miles for every 10 UPCs submitted). Phillips calculated that the return on a mail-in food promotion outweighed the price of the Healthy Choice frozen entrees, which were selling for $2. A few aisles away Phillips found boxes containing four Healthy Choice soup cans at 70 dollar cents. Because he did not need a freezer to store the soups, he immediately decided to purchase 200 boxes of soup cans. At home he first had some trouble explaining the hoarding behaviour to his wife, but during a subsequent visit to the supermarket they discovered together an aisle display of Healthy Choice Pudding. Normally, the pudding was sold in 4-cup packs, but the display had been intended to introduce the new pudding and the single sample cups — originally 39 cents — were on sale at just 25 cents each! A 25-cent pudding having its own barcode would thus bring 100 miles. Over the next few weeks he purchased a total of 12,000 pudding cups, claiming he was stocking up for Y2K. pudding Phillips and his wife had thus spent $3,140 in total for 800 soup cans and 12,000 pudding cups, but they had a problem. Not only could the family never consume this much soup and pudding, but more important they would not be able to remove the UPCs before the double certificate offer expired. After giving it some thought they enlisted the Salvation Army to help them peel off the UPC codes, in exchange for donating the pudding. He then mailed his submission to Healthy Choice, and to their credit they awarded him 1.25 million frequent-flyer miles — enough for 31 round trips to Europe, 42 to Hawaii, 21 to Australia, or 50 anywhere in the United States. There's no downside. Phillips also got Advantage Gold status for life with American Airlines, which brings a special reservations number, priority boarding, upgrades and bonus miles. And he got an $815 tax write off for donating the soup and the pudding. Input The following four numbers, each on a separate line: total number of items purchased of a certain product (integer) cost per item of the product (float) number of UPCs needed for a frequent-flyer coupon (integer) number of miles earned per frequent-flyer coupon (integer) Output A sentence describing the amount in dollars spent by Phillips to purchase all items of the product and the number of frequent-flyer miles he earned with this purchase. Use the output as given in the examples below as a template to format the sentence. The amount of money spent should be output as a floating point number and the number of frequent-flyer miles received as an integer. Example Input: 200 0.70 12 550 Output: Phillips spent $140.0 for 8800 frequent-flyer miles. Example Input: 12000 0.25 10 1000 Output: Phillips spent $3000.0 for 1200000 frequent-flyer miles.  |
| Sending http request from multiple threads using boost::asio. How to handle responses serially Posted: 02 Oct 2021 07:53 AM PDT For a client side application, I wish to serialize http post requests using strand, in order to avoid overlapping writes/ responses to/from the server. Serialization is made using boost::asio, by calling the method as a callback from strand.post as shown below. Notice that inside each http session (write request and read it's response, is made in a separated callback. (Notice that within the post, the http is made synchronously. boost::asio::io_context::strand strand_; void Send( boost::beast::http::request<boost::beast::http::string_body> &req) { strand_.post([=]() { boost::beast::http::request<boost::beast::http::string_body> req; // prepare request ... boost::beast::http::write(stream_, req); ... boost::beast::http::response<boost::beast::http::dynamic_body> res; boost::beast::flat_buffer buffer; boost::beast::error_code ec; boost::beast::http::read(stream_.socket(), buffer, res, ec); }
As can be seen from my example, the response reading is also made within the post callback. My question is whether this is actually required if I don't care about the ordering of reading the responses. can I assume that after each http request sent to the server boost::beast::http::write(stream_, req);, the data is already waiting in the rx buffer queue, so another thread may read the responses one-by-one ? thanks !  |
| Variable not being set in class using inheritance Posted: 02 Oct 2021 07:52 AM PDT I have an issue with the class below called ProjectileWeapon. It is based on an abstract class called Weapon, and that class inherits MonoBehaviour. Weapon has two abstract functions called BeginCycle and EndCycle which are implemented in the ProjectileWeapon class. Those functions set a variable called "firing". The problem is, "firing" doesn't ever seem to be set despite the functions being called correctly. I know the functions are called because I can see the prints in the console. Also, when I use that variable in the update function, it doesn't do anything because the variable never changes. The OnGUI function is working and is displaying text on screen, however the "firing" variable is never updated. Am I misunderstanding how to use inheritance? public class ProjectileWeapon : Weapon { private bool firing; private float firingTimer; void Start() { print("ProjectileWeapon start"); } void OnGUI() { GUI.Label(new Rect(0,100,100,100), "ProjectileWeapon firing: " + firing); } void Update() { // this function is called but "firing" is not updated } public override void BeginCycle() { print("projectile begin cycle"); firing = true; } public override void EndCycle() { print("projectile end cycle"); firing = false; } }
Here's the base class: public abstract class Weapon : MonoBehaviour { public abstract void BeginCycle(); public abstract void EndCycle(); }

| Count rows that have same value in all columns Posted: 02 Oct 2021 07:52 AM PDT If I have a dataframe like this: A B C D E F ------------------ 1 2 3 4 5 6 1 1 1 1 1 1 0 0 0 0 0 0 1 1 1 1 1 1
How can I get the number of rows that have value 1 in every column? In this case, 2 rows have 1 in every field. I know one way, for example if we only take columns A and B: count = df2.query("A == 1 & B == 1").shape[0]
But I have to put the name of every column, is there a more fancy approach? Thanks in advance  |

| Adding a normal curve on frequency histogram in R Posted: 02 Oct 2021 07:51 AM PDT I decided to go through my statistics courses, which are taught in SPSS, but do in R, as I would like to learn to do stats there. I am currently doing histograms for two numerical continuous varables data$alcohol (alcohol misuse scale score) and data$age but got stuck on the first one. The main issues are: - My histogram looks different from the picture in the answer sheet
- I cannot add a normal curve unless I change the
aes to density, which I do not want to do, as the exercise asks for frequency Here is what I wrote: data <- read_excel("~/Dropbox/My Mac (jmbp.local)/Desktop/Kings College London/2021:2022/Statistics/Week 1 stats/cleandata.xlsx") mean_alc <- mean(data$alcohol) sd_alc <- sd(data$alcohol) p <- ggplot(data= data) + geom_histogram(mapping = aes(x = alcohol, y=..count..), breaks=seq(0, 20, by=1), col="black", fill="white", alpha = 1) + labs(title="Alcohol Misuse Score", x="Alcohol Misuse Score", y="Frequency") + xlim(c(0,20)) + ylim(c(0,20)) + stat_function(fun = dnorm, colour = "red", args=list(mean = mean(data$alcohol), sd = sd(data$alcohol))) + plot(density(data$alcohol, bw = 0.05)) p
my histogram looks like this: My histogram the picture included in the solutions (done in SPSS) looks like this: Histogram in the answer sheet My first question is why the bars in my histogram look different than the ones in the answer sheet? is there some fundamanetal difference in how SPSS does histograms and how R does it? Secondly, is there a way to add a normal curve to the frequency histogram in ggplot 2? For reference this is how this can be done in SPSS: Frequency histogram with normal curve in SPSS the data$alcohol has the following values: alcohol = c(15.78121, 17, 17.61943, 17.61943, 14.67395, 17.61943, 17, 17, 13.72413, 13.72664, 17, 15.86039, 17, 15.78121, 11.48049, 14.61672, 12.73437, 8, 17, 15.86039, 14.59133, 15.78121, 14.61672, 17, 17, 18, 15.78121, 10, 14.67395, 9, 7.033369, 17, 17, 15.86039, 15.78121, 18, 13.07577, 18, 8, 17.61943, 15.86039, 11.53364, 11.4323, 18, 6.390277, 17, 14.59133, 18, 14.9238, 15.78121, 14.61672, 17, 17.61943, 14.67395, 8, 18, 8, 17.61943, 14.4069, 6.477451, 7.02489, 18, 18, 13.09201, 15.78121, 14.59133, 18, 5.451102, 9, 4.801972, 15.86039, 15.86039, 17, 17, 17)

| Typescript: Is it possible to ensure the key and an inner value are the same string? Posted: 02 Oct 2021 07:53 AM PDT I have a Record of data that could become large. I'm wondering if is it possible to enforce the key of the Record to be the same as the inner name value?. interface Person<T> { name: T title: string description: string } type People = Record<string, Person<string>> // example data const data: People = { sarah: { name: 'sarah', title: 'Sarah', description: 'Hello', } } const badData: People = { adam: { name: 'john', // This would cause a typescript error ideally. ... } }
I've tried setting up People with a generic but it would require me to add all the keys to a union type which I would rather avoid. keyof doesn't work as the object isn't defined where the keyof is needed. type People<T> = Record<T, Person<T>> const people: People<keyof typeof people> = {} // Block-scoped variable 'people' used before its declaration.ts(2448)

Output since there are 2 id present it will first add "nodesData" to "tempData" then compare node 1 data in "tempData" and then "node2" data will be compared to "tempData" here "attributes" and "mem" doesn't exist so add to "tempData" and then add temp node to "nodesData" How to execute this having trouble converting this to code ? { "cluster_name": "escluster", "nodesData":{ "timestamp": 1460624696217, "name": "master1", "transport_address": "10.0.0.1:9300", "host": "10.0.0.1:9300", "ip": [ "10.0.0.1:9300", "NONE" ], "attributes": { "data": "false", "master": "true" }, "os": { "timestamp": 1460624696217, "cpu_percent": 0, "load_average": 0, "swap": { "total_in_bytes": 0, "free_in_bytes": 0, "used_in_bytes": 0 }, "mem": { "free_percent": 84, "used_percent": 16 } } } } }
Tried marshal and unmarshalling but it overrides data if same key exist in case multiple ids are passed in nodeid Above approach https://play.golang.org/p/yXjf_htKJ3c  |
| Invoking API Gateway Endpoint from AWS Amplify gives CORS error Posted: 02 Oct 2021 07:53 AM PDT I am attempting to call an API endpoint in API gateway using a HTML website hosted in AWS Amplify. When I make the request: var xhrHeaders = new Headers(); xhrHeaders.append("Content-Type","application/json"); var requestOptions = { method: 'POST', headers: xhrHeaders, body: formData, redirect: 'follow', }; fetch("MyAPIGURL",requestOptions) .then(response => response.text()) .then(result => alert(JSON.parse(result).body)) .catch(error=>console.log('error', error))
I am consistently getting a CORS error: Access to fetch at 'XXXX' from origin 'https://XXXX.amplifyapp.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
However, I have gone into the API gateway and enabled CORS. I can see an OPTIONS endpoint has been created and a header mapping has been set: Access-Control-Allow-Origin '*'
I can see that coming back in the browser too: 1. access-control-allow-headers: Content-Type,X-Amz-Date,Authorization,X-Api-Key,X-Amz-Security-Token 2. access-control-allow-methods: OPTIONS,POST 3. access-control-allow-origin: * 4. content-length: 0 5. content-type: application/json 6. date: Fri, 01 Oct 2021 10:41:07 GMT
Yet it will not work and it is blocked at the browser. I have also tried adding mode: "no-cors" to my requestOptions but that does nothing. I can send requests via Postman as you'd expect but I'm a bit lost as to what to try next. Any ideas? Thanks  |
| Angular- Prevent selection of same options from a dropdown Posted: 02 Oct 2021 07:53 AM PDT I made this dropdown with a textarea for input in angular material dialog. There I have only three options in the dropdown(so far)-'English','French' and 'Canadian French'. I have already disabled 'English' by default. Now, for the rest of the remaining options, when I click 'Add new Language' button and select an option(french ; say) and add text I am able to disable the selected option so that when the user adds the third language they cannot select it again. It works fine. Like this (This is without hitting the save button)  Now the problem starts here. When I select 'French'(say) and hit the save button. And again open the dialog-box. I am again seeing 'French' along with 'Canadian French' in the options for the adding a third language. What do I do to make it inactive and grey-ish like 'English'? This the ts code: export class ModalAllComponent implements OnInit { dialogData: DialogDataModel; languages: any[]; rows: any[]; item!:any[]; constructor( public dialogRef:MatDialogRef<ModalAllComponent>, @Inject(MAT_DIALOG_DATA) public data: DialogDataModel) { this.dialogData = data; this.rows = this.dialogData.localisedEntities.filter(lang => lang.value,) this.languages = this.dialogData.localisedEntities.map(item => ({ code: item.code, title: item.title, canEdit: item.canEdit })) console.log(this.dialogData) } ngOnInit(): void { } addNewLanguage() { this.rows.push({ code: '', title: '', value: '', canEdit: true }); } onChangeValue(ev: any){ this.rows = this.rows.map(row => { if (row.code == ev.value) { const lang = this.languages.find(lang => lang.code == ev.value); row.title =lang.title; } return row; }) console.log(this.rows) this.languages = this.languages.map(lang => { if (lang.code == ev.value) { lang.canEdit = false; console.log(lang); } return lang; }); this.isDisabled() } isDisabled(){ return this.rows.filter((item) => item.value == '' || item.code == '') .length > 0 ? true : false; } submit(ev:any){ this.dialogRef.close({data: this.rows}); } back(){ this.dialogRef.close() } removeBtn(index:number){ this.rows.splice(index, 1); } }
I was console-logging at a lot of places and finally manage to draw down to these place where the problem might be happening. In console.log(lang), I saw that, when I selected 'French',the flag canEdit turned to false.But in console.log(this.rows), when I selected 'French',the flag canEdit did not turned to false How to solve the issue? The HTML code: <div> <table class="justify-content-between"> <tr *ngFor="let entity of rows; let i = index"> <td class="col-1" *ngIf="entity.value!=null"> <mat-select [(ngModel)]="entity.code" [disabled]="!entity.canEdit" (selectionChange)="onChangeValue($event)"> <mat-option *ngFor="let lang of languages" [disabled]="!lang.canEdit" [value]="lang.code">{{ lang.title }}</mat-option> </mat-select> <!-- <mat-error *ngIf="entity.code.hasError('required')">Please choose an language</mat-error> --> </td> <td class="col-1" *ngIf="entity.value!=null"> <textarea style="height: 2rem" class="pl-5" [disabled]="!entity.canEdit" [(ngModel)]="entity.value">{{ entity.value }}</textarea> <mat-icon class="pl-2" style="color: red;font-size: 2rem;cursor: pointer;" (click)="removeBtn(i)">close</mat-icon> </td> </tr> </table> <div class="d-flex flex-column align-items-center mt-2"> <button class="form-control" (click)="addNewLanguage()" *ngIf="rows.length < dialogData.localisedEntities.length" [disabled]="isDisabled()">Add new language</button> <div class="d-flex pt-2"> <button class="form-control" [disabled]="isDisabled()" (click)="back()">Discard</button> <button class="form-control ml-4 pl-4 pr-4" [disabled]="isDisabled()" (click)="submit($event)">Save</button> </div> </div> </div>
This is where the modal is opening: localiseFoodName() { const dialogData = < DialogDataModel > { localisedEntities: this.foodModel.localisedName.map((item: any) => { if (item.code == 'en') { item.canEdit = false; } else { item.canEdit = true; } return item; }), }; let dialogRef = this.dialog.open(ModalAllComponent, { width: '26.5rem', data: dialogData }); dialogRef.afterClosed().subscribe(res => { if (res && res.data) { console.log(res) console.log(res.data) let temp:any this.foodModel.localisedName.map((item:any)=>{ temp = res.data.find((element:any)=> element.code === item.code); if(temp){ item.value = temp.value item.canEdit = temp.canEdit = false } //console.log(temp) }) const food = this.foodModel.localisedName console.log(food) } }) }
When I console.log(food) I could see the canEdit:false. But when I open the modal again, in console.log(this.dialogData) the canEdit is again "True" for the selected item  Thanks in advance for the help!  |
| Is there a way to disallow creating a git branch with a particular name, locally? Posted: 02 Oct 2021 07:51 AM PDT I have some projects which use "master" and others which use "main" and I am constantly accidentally checking out one or the other. The big problem is when on a project that uses "main" and also heroku, which uses "master", so git checkout master succeeds and seems normal. Is there a way to configure something locally so that creating this branch will blow up?  |

I tried installing OpenSSL due to this question and also tried copying dll's as described here, but nothing works. Any suggestions?  |
| Separate scripts from .GlobalEnv: Source script that source scripts Posted: 02 Oct 2021 07:52 AM PDT This question is similar to Source script to separate environment in R, not the global environment, but with a key twist. Consider a script that sources another script: # main.R source("funs.R") x <- 1
# funs.R hello <- function() {message("Hi")}
I want to source the script main.R and keep everything in a "local" environment, say env <- new.env(). Normally, one could call source("main.R", local = env) and expect everything to be in the env environment. However, that's not the case here: x is part of env, but the function hello is not! It is in .GlobalEnv. Question: How can I source a script to a separate environment in R, even if that script itself sources other scripts, and without modifying the other scripts being sourced? Thanks for helping, and let me know if I can clarify anything. EDIT 1: Updated question to be explicit that scripts being source cannot be modified (assume they are not under your control).  |
| Angular 2 'component' is not a known element Posted: 02 Oct 2021 07:52 AM PDT I'm trying to use a component I created inside the AppModule in other modules. I get the following error though: "Uncaught (in promise): Error: Template parse errors: 'contacts-box' is not a known element: - If 'contacts-box' is an Angular component, then verify that it is part of this module.
- If 'contacts-box' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
My project structure is quite simple:  I keep my pages in pages directory, where each page is kept in different module (e.g. customers-module) and each module has multiple components (like customers-list-component, customers-add-component and so on). I want to use my ContactBoxComponent inside those components (so inside customers-add-component for example). As you can see I created the contacts-box component inside the widgets directory so it's basically inside the AppModule. I added the ContactBoxComponent import to app.module.ts and put it in declarations list of AppModule. It didin't work so I googled my problem and added ContactBoxComponent to export list as well. Didn't help. I also tried putting ContactBoxComponent in CustomersAddComponent and then in another one (from different module) but I got an error saying there are multiple declarations. What am I missing?  |
