| Get a byte array no encode/decode in base64 from REST Service - It's possible? Posted: 28 May 2022 09:51 PM PDT I was speculating how to receive a clean byte array from a wap-api (no encode/decode in base64). I still don't know if this is possible. Possibly there are things that I am doing wrong, or that I don't know yet. I have created a simple example to explain the issue. As you can see I'm just trying to send a text string encoded in a byte array, and decode it on the client side. Backend, a minimal API using System.Net; using System.Net.Http.Headers; using System.Text; var builder = WebApplication.CreateBuilder(args); var app = builder.Build(); app.MapGet("/GetQuote", () => HttpBinaryDataTest.GetQuote()); app.Run(); class HttpBinaryDataTest { public static HttpResponseMessage GetQuote() { var text = "I became insane, with long intervals of horrible sanity."; var bytes = Encoding.UTF8.GetBytes(text); var response = new HttpResponseMessage(HttpStatusCode.OK) { Content = new ByteArrayContent(bytes) }; response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream"); return response; } }
Frontend Test, a console application using System.Text; Console.WriteLine("Http Binary Test"); Console.WriteLine("Press any key to start..."); Console.ReadKey(); var h = new HttpTest(); var quote = await h.GetQuote(); Console.WriteLine(quote); Console.WriteLine("Press any key to end..."); Console.ReadKey(); h.Dispose(); // ------------------------------------------------------- class HttpTest : IDisposable { string apiRoot = "http://localhost:5274/"; // ApiTest readonly HttpClient client; public HttpTest() { client = new HttpClient { BaseAddress = new Uri(apiRoot) }; } public async Task<string> GetQuote() { var response = await client.GetAsync($"GetQuote"); var bytes = await response.Content.ReadAsByteArrayAsync(); var decodedText = Encoding.UTF8.GetString(bytes); // Should be: // I became insane, with long intervals of horrible sanity. return decodedText; } public void Dispose() => client?.Dispose(); }
When I run the client, what I get is a JSON, without errors, but I don't know how to get the data I expect. What am I missing? What am I doing wrong? The response: { "version": "1.1", "content": { "headers": [{ "key": "Content-Type", "value": ["application/octet-stream"] } ] }, "statusCode": 200, "reasonPhrase": "OK", "headers": [], "trailingHeaders": [], "requestMessage": null, "isSuccessStatusCode": true }

| Search bar using Window. Find in js and html Posted: 28 May 2022 09:49 PM PDT Hello I am trying to make a search bar to search anything which is available on a html page. I used window.find method.it highlights the string if its available in the html page. It returns a boolean value true or false. It gives false if the searched string is not available. But main problem is that it also returns false if all the searched strings are highlighted.Then how can I message the user that Nothing found OR searched text is already highlighted. I also want to Search again if button clicked again also when all the searched text is highlighted . I AM USING THIS CODE BUT ITS NOT COMPLETING MY ALL WISHES THAT I WANT. JS function SEARCH(){ var Search=document.getElementById("Search").value; var result=window.find(Search); if (result == false) { alert("Nothing found or already highlighted " ); } }
HTML <input class="FLDS" type="text" id="Search" placeholder="Search" /> <button onclick="SEARCH()" id="SEARCHIT">SEARCH</button> <p> A paragraph is a self-contained unit of discourse in writing dealing with a particular point or idea. A paragraph consists of one or more sentences. Though not required by the syntax of any language, paragraphs are usually an expected part of formal writing, used to organize longer prose. </p>

| Property 'text' does not exist on type 'Comment', but it does Posted: 28 May 2022 09:52 PM PDT {post?.comments?.map((comment) => ( <div>{comment.text}</div> ))}
Post is type Post, comments is type [Comment]. Here are the type definitions from another file. Unfortunately my project is too large to post all of it, and most is irrelevant to this problem anyways. I can post anything else that is needed upon request. I would also like to note that the code does not fail when executed, only annoying IDE complaints from Typescript that 'text' does not exist on type Comment. The subreddit property on Post does not have this problem, interestingly enough. type Comment { created_at: DateTime id: ID! post_id: ID text: String username: String } type Post { body: String created_at: DateTime id: ID! image: String subreddit_id: ID title: String username: String votes: [Vote] @materializer( query: "getVotesByPostId" arguments: [{ name: "post_id", field: "id" }] ) comments: [Comment] @materializer( query: "getCommentsByPostId" arguments: [{ name: "post_id", field: "id" }] ) subreddit: [Subreddit] @materializer( query: "getSubredditListById" arguments: [{ name: "id", field: "subreddit_id" }] ) }

| How to use variable condition to filter data in Pandas Posted: 28 May 2022 09:52 PM PDT I met a problem about Pandas using. I would like to use Pandas [xx==xx] style to filter something that fit this condition. Here is my code, for c in range(1,len(concept)+1): concept_name = "C"+str(c) data_concept = data[data["concept"] == concept_name] ... # do something in this data_concept
But it always gets "Empty Dataframe". When I directly set it to "C1", it gets data in which the column concept equal C1 correctly. data_concept = data[data["concept"] == "C1"]
I need to run all "C1" to "C9" conditions, so I use for-loop to try to finish this. I replace this condition with different numbers in every loop, so my thought is to use the variable to replace it. But it works not as I think. Please inform me where I am wrong. Thanks for your time. |
| HTML form not giving expected output every time Posted: 28 May 2022 09:51 PM PDT Description of the issue: I have made a form to send data from the front-end (JavaScript) to the back-end (PHP). The back-end is supposed to send a response back and then I can use fetch() to determine what to do from there. Now, the interesting thing is that this works... but not all of the time. Every now and then, the form decides not to send an alert message with the response message. It also - for some reason - shows the form parameters in the URL, which is not how it should happen: Unexpected output:  Expected output:  What have I tried? At first, I thought there might have been some duplicate code or a function somewhere that is sending the request twice but after a long and thorough search through all of the JavaScript files in the project, there is nothing that even hints towards it. I have debugged using alert(json.message) to see what the value of json.message is when the issue happens and nothing is logged to the console. I thought maybe it might have been something to do with my back-end API but after a trial of sending 20 of the same requests using Postman, every single trial did what it was supposed to do. Relevant code: var form = document.getElementById('registerForm'); form.addEventListener("submit", function(e) { if (!validateRegisterForm()) { e.preventDefault(); // Cancel form submission } else sendRegisterForm(); });
async function sendRegisterForm() { try { var formData = new FormData(form); let res = await fetch("http://localhost/backend/api/users/register", { method: 'POST', body: formData, }); var json = await res.json(); alert(json.message); if (res.status === 200) location.reload(); // If user login is successful, refresh the page } catch (error) { console.log(error); } }

I want to align the image and find the coordinates of top left top right and bottom left and bottom right contours. here is my code so far where I can identify all the contours. gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) blur = cv2.GaussianBlur(gray,(3,3),0) edges = cv2.Canny(blur,50,100) contours, hierarchy = cv2.findContours(edges,cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE) #find contours cv2.drawContours(img,contours,-1,(0,255,0),2) cv2.imshow('Contours',img) cv2.waitKey(0)
Here is an image of what I get. 
I'd be very thankful if you could try to help me solve this problem! |
| Terraform 'default_tags' behaviour for aws resources with 'default' tag value Posted: 28 May 2022 09:50 PM PDT I am facing issue while using 'default_tags' for all AWS resources deployed using Terraform. We have multiple reusable modules in a project. Now, I wanted to assign few tags to all AWS resources, I am using 'default_tags' for it and while TF apply it gives 'dependency cycle' issue. In some of tags there are "default={}" are set [working on existing TF project]. I wanted to understand that is there any impact of "default_tags" on declared tags per resource level? Please refer below code, //outputs.tf resource "null_resource" "dependencies" { depends_on = [ aws_security_group_rule.cluster_k8s_ingress ] } //main.tf module "eks" { source = "terraform-aws-modules/eks/aws" version = "18.7.2" cluster_additional_security_group_ids = [aws_security_group.additional_eks_sg.id] vpc_security_group_ids = [aws_security_group.additional_eks_worker_sg.id] } //sg.tf resource "aws_security_group_rule" "cluster_k8s_ingress" { cidr_blocks = data.aws_subnet.private.*.cidr_block description = "Allows ingress traffic from private subnets to Node Ports" from_port = local.start_port to_port = local.end_port protocol = "tcp" security_group_id = module.eks.cluster_primary_security_group_id type = "ingress" }

| Creating and plotting confidence intervals Posted: 28 May 2022 09:50 PM PDT I have fitted a gaussian GLM model to my data, i now wish to create 95% CIs and fit them to my data. Im having a couple of issues with this when plotting as i cant get them to capture my data, they just seem to plot the same line as the model without captuing the data points. Also Im also unsure that I've created my CIs the correct way here for the mean. I entered my data and code below if anyone knows how to fix this data used aids cases quarter date 1 2 1 83.00 2 6 2 83.25 3 10 3 83.50 4 8 4 83.75 5 12 1 84.00 6 9 2 84.25 7 28 3 84.50 8 28 4 84.75 9 36 1 85.00 10 32 2 85.25 11 46 3 85.50 12 47 4 85.75 13 50 1 86.00 14 61 2 86.25 15 99 3 86.50 16 95 4 86.75 17 150 1 87.00 18 143 2 87.25 19 197 3 87.50 20 159 4 87.75 21 204 1 88.00 22 168 2 88.25 23 196 3 88.50 24 194 4 88.75 25 210 1 89.00 26 180 2 89.25 27 277 3 89.50 28 181 4 89.75 29 327 1 90.00 30 276 2 90.25 31 365 3 90.50 32 300 4 90.75 33 356 1 91.00 34 304 2 91.25 35 307 3 91.50 36 386 4 91.75 37 331 1 92.00 38 368 2 92.25 39 416 3 92.50 40 374 4 92.75 41 412 1 93.00 42 358 2 93.25 43 416 3 93.50 44 414 4 93.75 45 496 1 94.00
my code used to create the model and intervals before plotting #creating the model model3 = glm(cases ~ date, data = aids, family = poisson(link='log')) #now to add approx. 95% confidence envelope around this line #predict again but at the linear predictor level along with standard errors my_preds <- predict(model3, newdata=data.frame(aids), se.fit=T, type="link") #calculate CI limit since linear predictor is approx. Gaussian upper <- my_preds$fit+1.96*my_preds$se.fit #this might be logit not log lower <- my_preds$fit-1.96*my_preds$se.fit #transform the CI limit to get one at the level of the mean upper <- exp(upper)/(1+exp(upper)) lower <- exp(lower)/(1+exp(lower)) #plotting data plot(aids$date, aids$cases, xlab = 'Date', ylab = 'Cases', pch = 20) #adding CI lines plot(aids$date, exp(my_preds$fit), type = "link", xlab = 'Date', ylab = 'Cases') #add title lines(aids$date,exp(my_preds$fit+1.96*my_preds$se.fit),lwd=2,lty=2) lines(aids$date,exp(my_preds$fit-1.96*my_preds$se.fit),lwd=2,lty=2)
outcome i currently get with no data points, the model is correct here but the CI isnt as i have no data points, so the CIs are made incorrectly i think somewhere

| .Net 6 - Passing a radio button selected table row to a controller Posted: 28 May 2022 09:51 PM PDT I really feel like this should be easy but I'm thinking it may have changed with .Net 6. I can pass values to my controller with the input "name='name'" but for some reason I cannot get any values from my model into my controller. I am trying to POST my row values to the controller. I am using an enumerable. I'm not sure if I should be using a or not. Another thing is how should I be populating my table row from a loop of the model. I thought using @Html.

| Access-Control-Request-Private-Network header issues Posted: 28 May 2022 09:50 PM PDT Today we updated the last version of google chrome browser (Version 102.0.5005.61). We have an aplication that runs into a vpn. And since then we start getting this errors on the console:  As you can see we get a timed out error on the preflight and then the xhr request fails. We noticed that on this version of chorme they add the new header: Access-Control-Request-Private-Network. An that is what I see on the preflight headers: 
Serching on what could be wrong, since this is happening only when we update the chrome version and in other browsers the site works perfectly; Ive found this: https://developer.chrome.com/blog/private-network-access-preflight/ On the article is explained what to do and how to handle this. And show kind of what is happening to me: If your request would have triggered a regular CORS preflight without Private Network Access rules, then two preflights may appear in the network panel, with the first one always appearing to have failed. This is a known bug, and you can safely ignore it. Based on that I added the new header support on my API that is made on JAVA with spring boot. response.setHeader("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT, OPTIONS"); response.setHeader("Access-Control-Allow-Headers", "content-type"); response.setHeader("Access-Control-Allow-Credentials", "true"); response.setHeader("Access-Control-Max-Age", "180"); response.setHeader("Access-Control-Allow-Private-Network", "true"); response.setHeader("Access-Control-Expose-Headers", "Content-Disposition");
As you can see just added the header and return 200 for the option request if ("OPTIONS".equals(request.getMethod())) { response.setStatus(HttpServletResponse.SC_OK); return; }
The site is running, meaning it get served and is loaded on chrome browser but all the API calls from the site get that error. (See screen shoots avobe). But still after that have the same issues. Any one had the same issue and was able to solve? Any help will be appreciated! Thanks! EDIT: We just add the headers on the preflight response: Access-Control-Request-Private-Network: true Access-Control-Allow-Private-Network: true Then we go to the google flags configuration and disable this:  Now Im not sure why google thinks that my requests are insecure. |

| What is the use case of atomFamily in recoil? Posted: 28 May 2022 09:51 PM PDT I did my first experiment with recoil, building an editable table. Each cell has an atom which stores its row, column, and text value. The way I built this was by - initializing each cell's atom into a dictionary (just a plain object), with keys in a format of [column]x[row]
- I then iterate over these keys in the Table component, and pass only the key to each Cell component
- The Cell component uses
useRecoilState and find its specific Atom by accessing the main dictionary using the key it got passed as a prop. Now, it seems to me that this use case (creating thousands of related atoms with the same shape) is what atomFamily is meant to make easier, but I don't understand how to use it in this way, where you initialize each atom with a specific value. And, besides that, I don't understand what is the advantage of using atomFamily over storing a collection of atoms. I understand there is memoization involved, but I don't understand what is getting memoized other than, if I am reading correctly, the ability to recall a specific atom by calling the function again with the same id, which would get you pretty much the same behavior I'm getting with a dictionary. |

| Firefox does not print table borders on pages 2 and onwards Posted: 28 May 2022 09:51 PM PDT Problem: When printing a table on Mozilla Firefox (version 55.0.3 32bit), table borders show on the first page only, but not on any of the subsequent pages. So, i.e. printing pages 2 only does not print table borders, but printing page 1 only prints table borders.

| Optimal number of threads per core Posted: 28 May 2022 09:52 PM PDT Let's say I have a 4-core CPU, and I want to run some process in the minimum amount of time. The process is ideally parallelizable, so I can run chunks of it on an infinite number of threads and each thread takes the same amount of time. Since I have 4 cores, I don't expect any speedup by running more threads than cores, since a single core is only capable of running a single thread at a given moment. I don't know much about hardware, so this is only a guess. Is there a benefit to running a parallelizable process on more threads than cores? In other words, will my process finish faster, slower, or in about the same amount of time if I run it using 4000 threads rather than 4 threads? |
