| JS - how to unpin mouse after right click on draggable modal? Posted: 04 Apr 2021 10:28 AM PDT I am dragging a modal using the following code: function makeDivDraggable(modal) { let x = 0; let y = 0; // Query the element const ele = modal; ele.style.cursor = "move"; // Handle the mousedown event // that's triggered when user drags the element const mouseDownHandler = function(e) { // Get the current mouse position x = e.clientX; y = e.clientY; // Attach the listeners to `document` document.addEventListener('mousemove', mouseMoveHandler); document.addEventListener('mouseup', mouseUpHandler); }; const mouseMoveHandler = function(e) { // How far the mouse has been moved const dx = e.clientX - x; const dy = e.clientY - y; // Set the position of element ele.style.top = `${ele.offsetTop + dy}px`; ele.style.left = `${ele.offsetLeft + dx}px`; // Reassign the position of mouse x = e.clientX; y = e.clientY; }; const mouseUpHandler = function() { // Remove the handlers of `mousemove` and `mouseup` document.removeEventListener('mousemove', mouseMoveHandler); document.removeEventListener('mouseup', mouseUpHandler); }; ele.addEventListener('mousedown', mouseDownHandler); }; }
it works everything great, apart from one little thing. If in the modal there are some links, those links open well to a new tab thanks to the _target="blank" however, if I right click on a link, and I select to open to a new tab, the tab opens, however the div remains "clicked", but not unclicked", it means that no matter where the cursor goes, the modal follows the cursor, even though no mouse buttons are being clicked. I am thinking of a solution to: -ignore right clicks and make it move only with left clicks. -or unpin the mouse - delete the event listener as soon as the right click was done Can you please suggest a solution? And how to edit the code to make it work?  |

I was doing the validations on my presentation layer on my controller, but then I'm trying to pass it on to my domain my scenario is: I have 2 values objects: Password: min length 8 Email: is email Customer-entity: interface CustomerProps { id: CustomerID name: string email: CustomerEmail password: CustomerPassword } export class Customer extends Entity<CustomerProps> implements CustomerProps { private _id: CustomerID private _name: string private _email: CustomerEmail private _password: CustomerPassword constructor(props: CustomerProps) { super(props) this._id = props.id this._name = props.name this._email = props.email this._password = props.password } get id(): CustomerID { return this._id } get email(): CustomerEmail { return this._email } get name(): string { return this._name } get password(): CustomerPassword { return this._password } public static build() {} }
Customer-Password: export class CustomerPassword { private readonly pwd: string private constructor(pwd: string) { this.pwd = pwd Object.freeze(this) } public async comparePassword(plainTextPassword: string): Promise<boolean> { // need implements } public async encrypt(): Promise<string> { // need implements } static create(pwd: string): Either<IErrorModel, CustomerPassword> { if (!pwd) return left(makeRequiredFieldError('Password')) if (pwd.length < 8) return left(makeMinFieldError('passwrod', 8)) return right(new CustomerPassword(pwd)) } get value(): string { return this.pwd } }
Customer-Email: export class CustomerEmail { private readonly email: string private constructor(email: string) { this.email = email Object.freeze(this) } static create(email: string): Either<IErrorModel, CustomerEmail> { if (!Email.validate(email)) { return left({ code: 'InvalidEmail', reason: 'Provide a valid email', field: 'email', }) } return right(new CustomerEmail(email)) } get value(): string { return this.email } static validate(email: string): boolean { if (!validator.isEmail(email)) return false return true } }
In my values objects I do the validations in a static method called create and so I'm not sure if that's correct and also creating a static create method on my customer-entity. is it possible to apply a facade in this situation? Is it okay to do the validations at that level?  |

| Dist function between matrix objects in R Posted: 04 Apr 2021 10:28 AM PDT I have a very simple problem. Given a N dimension point (say, a vector where each element represents a dimension) represented by x and a MxN dimension matrix (or a group of M points that have N dimensions!) represented by y. set.seed(999) data <- matrix(runif(1100), nrow = 11, ncol = 10) x <- data[1, ] y <- data[2:nrow(data), ]
I want to calculate a distance measure between x and every point of y. I know a simple way of doing that is to do: distances <- dist(rbind(x, y))
However, I believe this is not very efficient for this specific case, for the following reasons: - I need to use rbind, which is very memory costly.
dist calculates the distance between every point, but I'm only interested in 10 of those distances, or simply the distance between x and every point of y. I'm not interested in the internal distances between y points.- Because of (2) I need to manually select the last line of the dist matrix to get the distances I actually need.
One possible solution I thought of was to apply the distance measurement manually looping through y. distances <- apply(y, MARGIN = 1, function(a, b = x) { sqrt(sum((a - b)^2)) })
However, when timing both approaches, I get: func1 <- function(x, y) { apply(y, MARGIN = 1, function(a, b = x) { sqrt(sum((a - b)^2)) }) } func2 <- function(x, y) { dist(rbind(x, y)) } microbenchmark::microbenchmark( func1(x, y), func2(x, y) ) Unit: microseconds expr min lq mean median uq max neval func1(x, y) 29.602 30.450 61.21791 31.301 32.3510 2916.101 100 func2(x, y) 15.101 15.801 28.55304 17.201 17.7015 1143.001 100
So my question here is: is there a way to solve this problem faster than using dist?  |

I notice that I can set it on the deployment (upon creation) or on the replicaset. the code looks as such : package main import ( "net/http" "fmt" "io/ioutil" "encoding/json" "os" // "github.com/golang/glog" "strconv" "k8s.io/api/admission/v1" // corev1 "k8s.io/api/core/v1" appsv1 "k8s.io/api/apps/v1" metav1 "k8s.io/apimachinery/pkg/apis/meta/v1" admissionv1 "k8s.io/api/admission/v1" ) func isKubeNamespace(ns string) bool { return ns == metav1.NamespacePublic || ns == metav1.NamespaceSystem } type patchOperation struct { Op string `json:"op"` Path string `json:"path"` Value interface{} `json:"value,omitempty"` } func (mr *myServerHandler) mutserve(w http.ResponseWriter, r *http.Request) { var Body []byte if r.Body != nil { if data , err := ioutil.ReadAll(r.Body); err == nil { Body = data } } if len(Body) == 0 { fmt.Fprintf(os.Stderr, "Unable to retrieve Body from API") http.Error(w,"Empty Body", http.StatusBadRequest) } fmt.Fprintf(os.Stdout,"Received Request") if r.URL.Path != "/mutate" { fmt.Fprintf(os.Stderr, "Not a Validate URL Path") http.Error(w, "Not A Validate URL Path", http.StatusBadRequest) } // Read the Response from the Kubernetes API and place it in the Request arRequest := &v1.AdmissionReview{} if err := json.Unmarshal(Body, arRequest); err != nil { fmt.Fprintf(os.Stderr, "Error Unmarsheling the Body request") http.Error(w, "Error Unmarsheling the Body request", http.StatusBadRequest) return } // if arRequest.Request.Resource.Resource != "pods" { // fmt.Fprintf(os.Stderr, "Handling the wrong resource") // http.Error(w, "Handling the wrong resource", http.StatusBadRequest) // return // } raw := arRequest.Request.Object.Raw replicaset := appsv1.ReplicaSet{} if !isKubeNamespace(arRequest.Request.Namespace) { if err := json.Unmarshal(raw, &replicaset); err != nil { fmt.Fprintf(os.Stderr, "Error , unable to Deserializing Pod") http.Error(w,"Error , unable to Deserializing Pod", http.StatusBadRequest) return } } else { fmt.Fprintf(os.Stderr, "Error , unauthorized Namespace") http.Error(w,"Error , unauthorized Namespace", http.StatusBadRequest) return } containers := replicaset.Spec.Template.Spec.Containers arResponse := v1.AdmissionReview{ Response: &v1.AdmissionResponse{ UID: arRequest.Request.UID, }, } var patches []patchOperation for i , container := range containers { fmt.Fprintf(os.Stdout, "container[%d]= %s imagePullPolicy=%s", i, container.Name , container.ImagePullPolicy) if containers[i].ImagePullPolicy != "Always" { if containers[i].ImagePullPolicy == "Never" || containers[i].ImagePullPolicy == "IfNotPresent" { patches = append(patches, patchOperation{ Op: "replace", Path: "spec/template/spec/containers/[" + strconv.Itoa(i) + "]/ImagePullPolicy", Value: "Always", }) } else { patches = append(patches, patchOperation{ Op: "Add", Path: "/spec/template/spec/containers/[" + strconv.Itoa(i) + "]/ImagePullPolicy", Value: "Always", }) arResponse.Response.Allowed = true } } } // if pullPolicy != "Always" { patchBytes, err := json.Marshal(patches) if err != nil { fmt.Fprintf(os.Stderr, "Can't encode Patches: %v", err) http.Error(w, fmt.Sprintf("couldn't encode Patches: %v", err), http.StatusInternalServerError) return } v1JSONPatch := admissionv1.PatchTypeJSONPatch arResponse.APIVersion = "admission.k8s.io/v1" arResponse.Kind = arRequest.Kind arResponse.Response.Allowed = true arResponse.Response.Patch = patchBytes arResponse.Response.PatchType = &v1JSONPatch resp, rErr := json.Marshal(arResponse) if rErr != nil { fmt.Fprintf(os.Stderr, "Can't encode response: %v", rErr) http.Error(w, fmt.Sprintf("couldn't encode response: %v", rErr), http.StatusInternalServerError) } if _ , wErr := w.Write(resp); wErr != nil { fmt.Fprintf(os.Stderr, "Can't write response: %v", wErr) http.Error(w, fmt.Sprintf("cloud not write response: %v", wErr), http.StatusInternalServerError) } }
if I run the "Add" patch it does end up adding the imagePullPolicy to always but if I want to replace it I am receiving an error of : "Failed to create new replica set "ubi-kuku-547654586": Internal error occurred: replace operation does not apply: doc is missing path: /spec/template/spec/containers/[0]/ImagePullPolicy: missing value" I have tried it when creating a deployment and it is still the same error I tried working with the same structure (different path) for a single pod ( /spec/containers/[0]/ImagePullPolicy) with the core/v1 package and it worked.  |
| Player can't move across the x-axis while on top a platform that has collisions with it Posted: 04 Apr 2021 10:27 AM PDT I am using Game Maker Studio: 2 to make a game currently. I have a problem where the player won't move left or right while on top of a platform that it is colliding with. Any help would be great! //velocity = 2 //Moving left if (keyboard_check(65)) { x -= velocity*delta_time/17500; } //Moving right if (keyboard_check(68)) { x += velocity*delta_time/17500; }

| In Asp.Net core Odata, how to prevent filter string from replacing text passed Posted: 04 Apr 2021 10:28 AM PDT I am passing an odata query as below http://localhost:5000/odata/Levels?$filter=contains(Code, '+14')
However when this lands in my controller I see that the filter object received is being replaced as {contains(Code, ' 14')}
As you can see +14 is being replaced 14 where + is replaced with a space due to which my query is failing. How can I fix this issue?  |
| Dynamic field creation google forms Posted: 04 Apr 2021 10:28 AM PDT Is it possible to add questions to a google form based on if the user wants to add a few more clusters of data? i.e. a user is asked to enter information about the pets they have. If they have one pet, a user enters information for one pet. if the user wants to add another pet, they are prompted and asked if they want to add another pet. The user then selects yes, and another few fields appear. When the user is done adding pets, they say they are done, and move on. I assume using a class form would allow me to add a text field, but is there an issue with how the information is pushed to the spreadsheet? This example says that although you can add fields, you cannot capture the data into a spreadsheet since they are already formed. How can I add dynamic field in Google Form? Thanks  |

| How to hide nginx.conf authorization credentials? Posted: 04 Apr 2021 10:27 AM PDT To explain quickly, I have an nginx server running within Docker, acting as a reverse proxy for my Flask web app. A part of my configuration is using proxy_set_header Authorization to pass some credentials into the proxy_pass website. This all works fine - but, I want to push all this stuff to GitHub, and of course don't want want my creds, encoded or not, to show up. What is my best option here? All I can think of is having something similar to dotenv, but for nginx.conf files rather than .py files. Does anyone have any ideas on what I could to in order to pass my creds in but without hardcoding them explicitly in the config?  |
| Trying to access a value outside of another function [duplicate] Posted: 04 Apr 2021 10:27 AM PDT How can I get the array values inside of a function, outside of the function? I'm trying to access the content of the database outside of the function responsible for getting the data, by filling in an array with the rows comming out of the database. In this example case the variable datainfo was created to copy the rows and be accessible outside of the get function, but when trying to access it or displaying its content I get the information the value it contains is [] which is its initial value. Currently I was trying with the async because I thought it had to do with that, but it still doesn't work. async GetDateForCopyFromDatabase(){ let playlistId = 1; var dbOrigin = new sqlite3.Database('./db/dbname.db', sqlite3.SQLITE_OPEN_CREATE, (err) => { if (err) { console.error('Origin: ' + err.message); } console.log('Connected to the origin database.'); }); let sql = `SELECT xpto FROM table1 WHERE id = ?`; var datainfo = []; await dbOrigin.get(sql,[playlistId], function(err, data) { if (!err) { datainfo = data; } }); console.log(datainfo); }
