| All Invalid Random Paths in the URL Return The Normal Web Page Instead of 404 Not Found Page Posted: 22 Jun 2022 10:34 AM PDT I have a website: https://www.includekarabuk.com
For instance this url contains an article: https://www.includekarabuk.com/kategoriler/genel/Siber-Guvenlikte-Dusuk-Seviye-Aciklik-Nedir.php
But when I add invalid path to the existing url, page is still being showed. https://www.includekarabuk.com/kategoriler/genel/Siber-Guvenlikte-Dusuk-Seviye-Aciklik-Nedir.php/test123343242314321423423423/ https://www.includekarabuk.com/kategoriler/genel/Siber-Guvenlikte-Dusuk-Seviye-Aciklik-Nedir.php/sdfdsfdsfsdfdsfsdfsdfsdfsdsdfdsfsdfd/ https://www.includekarabuk.com/kategoriler/genel/Siber-Guvenlikte-Dusuk-Seviye-Aciklik-Nedir.php/132432432/
But because css and javascript file locations will be invalid due to added extra path, page is displayed as broken. I want to stop this. When the web server receives invalid path as with above, it should respond as 404 not found page coming from web server. How can I do that? I am using Apache web server and php scripting language. Note: I am not using any MVC framework. |

| ASP.NET core authentication and authorization with OIDC without creating local copies of the user Posted: 22 Jun 2022 10:34 AM PDT I've just created a new ASP.net core application using visual studio, it has the Authentication Type set to Individual Accounts: 
I've added some code to handle OIDC: builder.Services.AddAuthentication().AddOpenIdConnect(openIdOptions => { openIdOptions.ClientId = "myClientId"; openIdOptions.Authority = "myAuthority"; openIdOptions.ResponseType = OpenIdConnectResponseType.Code; openIdOptions.GetClaimsFromUserInfoEndpoint = false; openIdOptions.CallbackPath = "/signin-oidc"; openIdOptions.SaveTokens = true;
Which is all well and good, I can click to login with OpenIdConnect:  When I log in with the provided credentials it pops up asking me to Associate my OpenIdConnect account:  I don't want to have to do this. Retrieving the access token and id token is sufficient for what I want to do, I don't require a local copy of the user. Being new to ASP.net and having not used Razor before it's not immediately obvious what code I should delete — if that's even the correct approach. I've played around with deleting various bits such as the Db setup as I don't really require it, although I suspect Razor does in some regard. The Program.cs looks as follows: var builder = WebApplication.CreateBuilder(args); // Add services to the container. var connectionString = builder.Configuration.GetConnectionString("DefaultConnection"); builder.Services.AddDbContext<ApplicationDbContext>(options => options.UseSqlServer(connectionString)); builder.Services.AddDatabaseDeveloperPageExceptionFilter(); builder.Services.AddDefaultIdentity<IdentityUser>(options => { }) .AddEntityFrameworkStores<ApplicationDbContext>(); builder.Services.AddRazorPages(); builder.Services.AddAuthentication().AddGoogle(googleOptions => { googleOptions.ClientId = builder.Configuration["Authentication:Google:ClientId"]; googleOptions.ClientSecret = builder.Configuration["Authentication:Google:ClientSecret"]; }); builder.Services.AddAuthentication().AddOpenIdConnect(openIdOptions => { openIdOptions.ClientId = "clientId"; openIdOptions.Authority = "authority"; openIdOptions.ResponseType = OpenIdConnectResponseType.Code; openIdOptions.GetClaimsFromUserInfoEndpoint = false; openIdOptions.CallbackPath = "/signin-oidc"; openIdOptions.SaveTokens = true; }); var app = builder.Build(); // Configure the HTTP request pipeline. if (app.Environment.IsDevelopment()) { app.UseMigrationsEndPoint(); } else { app.UseExceptionHandler("/Error"); // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts. app.UseHsts(); } app.UseHttpsRedirection(); app.UseStaticFiles(); app.UseRouting(); app.UseAuthentication(); app.UseAuthorization(); app.MapRazorPages(); app.UseEndpoints(endpoints => { endpoints.MapControllerRoute("default", "{controller=Home}/{action=Index}"); }); app.Run();

| How to view container logs in GKE's Logs Explorer Posted: 22 Jun 2022 10:33 AM PDT In my GKE cluster (version v1.21.10-gke.2000) I would like to see output produced by pods/containers as logs in Logs Explorer. But clicking on Container Logs link in Workloads' Overview tab makes Logs Explorer return 'No data found'. Cloud Logging is enabled (Components: System, Workloads). Cloud Logging API is enabled as well. What I have tried so far: In another (test) project in a freshly created cluster (version 1.22.8-gke.201) this works correctly, i.e. what kubectl logs returns is also visible in Logs Explorer. The cluster mentioned at the beginning was created long ago and apparently requires some changes - how can I figure out what cluster (or maybe node pool) settings need to be modified to be able to see container logs in Logs Explorer? I would like to avoid creating a new cluster from scratch. |
| How do I type a Response object from a fetch request? Posted: 22 Jun 2022 10:34 AM PDT I'm running parallel requests for a series of fetches. I want to type results as an array of response objects (instead of array of type any) but I'm unsure of how to do this. I googled "how to type response object in Typescript" but didn't get useful hits. Is there a way to type the response object other than manually creating a custom type that has all the properties on a response object? Does Typescript have a special built in type we could use here? const results: any = []; fetch(URL, { headers: { ... } }) .then(response => { results.push(response); }) .catch(err => { ... }) const responses = await Promise.all(results); return responses;

| Find minimum steps to convert all elements to zero Posted: 22 Jun 2022 10:34 AM PDT You are given an array of positive integers of size N. You can choose any positive number x such that x<=max(Array) and subtract it from all elements of the array greater than and equal to x. This operation has a cost A[i]-x for A[i]>=x. The total cost for a particular step is the sum(A[i]-x). A step is only valid if the sum(A[i]-x) is less than or equal to a given number K. For all the valid steps find the minimum number of steps to make all elements of the array zero. 0<=i<10^5
0<=x<=10^5
0<k<10^5 Can anybody help me with any approach? DP will not work due to high constraints. |

| Best AWS Hardware for SIMD-JSON [closed] Posted: 22 Jun 2022 10:34 AM PDT I'm writing an application that involves parsing a good deal of JSON. I'm using the SIMD-JSON library. However, I understand that its performance depends a large degree on the hardware used. What should I look for when choosing hardware for SIMD-JSON-parsing-intensive work? EDIT: due to objections of asking for the "best choice" of hardware, I've amended the question. EDIT: not sure why this is closed, at a minimum the library requires x86. AWS-specific is important because it can be unclear what the hardware is that amazon offers, even when they claim the virtual hardware meets certain requirements. |
| Cross-Origin problems when trying to send a POST request Posted: 22 Jun 2022 10:34 AM PDT I'm working on the frontend of a website with vanilla JS and I'm trying to use the Hapio API which basically allows you to book appointments. In order to create a new service (It's a barbershop website) I'm using the fetch web API to send a POST request. The API requires me to perform authentication using a bearer token, also I need to provide some parameters in the body of the request. I have the following code: //Params needed to create a new service const service = { name: 'Haircut 1', type: 'fixed', duration: 'PT45M', } fetch('https://eu-central-1.hapio.net/v1/services', { method: 'POST', headers: { "Content-Type": "application/json", "Authorization": `Bearer ${token}`, }, body: JSON.stringify(service), }). then(resp => resp.json()). then(data => console.log(data))
I'm just testing the endpoint on the Firefox console and I get the next error: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://eu-central-1.hapio.net/v1/services. (Reason: CORS header 'Access-Control-Allow-Origin' missing). Status code: 200. I tried to run the same code on different browsers and I get different errors. This one for example is on Safari: [Error] Origin null is not allowed by Access-Control-Allow-Origin. Status code: 200 I googled a bit and most people say that I have to enable CORS on the server I'm trying to send the request to, but the thing is that I don't have control of it. I noticed that the Origin header is set to null. Any idea of how can I fix the problem? |

the structure of html tag is following: the whole grid of items on the page is within div class "properties_reviews" which then goes into div class "preview" for a particular item and that class "preview" has two more classes: "preview-media" for photo and "preview-content" for text info i need to parse. the class "preview-content" has [a] tag that contains two [span] tags with price and square of the item, and a [h2] tag with a territory i also need. <div class="properties-previews"> <div class="preview" <div class="preview-media"> <div class="preview-content"> <a href="/properties/1042-us-highway-1-hancock-me-04634/1330428" class="preview__link"> <span class="preview__price">$89,900</span> <span class="preview__size">1 ac</span> <div class="preview__subtitle"> <h2 class="-g-truncated preview__subterritory">Hancock County </h2> <span class="preview__extended">-- sq ft</span> </div> </a>
so i am trying to get out $89,990 from preview_price; 1 ac from preview_size; hancock county from preview_subtitle and my python code so far has been something like this (i have omitted all imports and requests): landplots = soup.find_all('div', class_ = 'properties-previews') for l in landplots: plot_price = l.find('span', {"class": 'preview_price'}) plot_square = l.find('span', {"class": 'preview_size'}) plot_county = l.find('h2', class_ = '-g-truncated preview__subterritory').text plot_location = l.find('span', class_ = 'preview__locality -g-truncated').text print(plot_price).text print(plot_county)
what am i doing wrong? i've come to understanding that once a tag is within another tag there should be some special syntax to get those words, but the error saying i have no text at all (on both prints i am doing) confuses me a lot. please help! |

How would I be able to do this without regex. We have a string str = "%greet%! Hi there, %var_1% that can be any other %var_2% injected to the %var_3%. Nice!, goodbye)" we have a hash called dict = { greet: 'Hi there', var_1: 'FIRST VARIABLE', var_2: 'values', var_3: 'string', } This was my solution: def template(str, dict) vars = value.scan(/%(.*?)%/).flatten vars.each do |var| value = value.gsub("%#{var}%", dict[var.to_sym]) end value end

| How do I assign a Boolean when value is missing using CROSSTAB? Posted: 22 Jun 2022 10:33 AM PDT I need help from the beehive. I am currently learning to use CROSSTAB in Postgres and have run into a blocker. Here's what I am getting: | contactid | opt_in | purchase | deleted | | 1 | 1 | 1 | 0 | | 2 | 0 | 1 | 1 | | 3 | 1 | 0 | 0 | Here's what I should get: | contactid | opt_in | purchase | deleted | | 1 | 1 | 1 | 0 | | 2 | 1 | 1 | 0 | | 3 | 0 | 0 | 1 | Now, as I understand, CROSSTAB takes the first value it finds and uses it for the first feature that is called, which is why contacted 3 has a 1 in opt-in instead of deleted, and why contacted 2 has a 0 in opt-in when it should be a 1. I just don't know how to fix this without upserting rows to the original table. Would really appreciate your guidance. Here's my script: CREATE EXTENSION IF NOT EXISTS tablefunc; with happening as (SELECT * FROM CROSSTAB($$ with happening as ( select distinct activity, a.contactid, case when activitydate<=creationdate+interval '2 weeks' then 1 else 0 end happening from contactactivities a left join contacts c on a.contactid=c.contactid group by activity, a.contactid, happening order by a.contactid) select contactid, activity, happening from happening order by contactid, activity; $$) AS happening (contactid int, opt_in int, purchase int, deleted int)) select contactid, coalesce(opt_in,'0'::int) opt_in, coalesce(purchase,'0'::int) purchase, coalesce(deleted,'0'::int) deleted from happening;
Schema: CREATE TABLE IF NOT EXISTS contacts ( CONTACTID SERIAL, CREATIONDATE DATE ); CREATE TABLE IF NOT EXISTS contactActivities ( CONTACTID INT, ACTIVITY VARCHAR, ACTIVITYDATE DATE ); INSERT INTO contacts(CREATIONDATE) VALUES ('1/22/20'), ('1/25/20'), ('1/26/20'); INSERT INTO contactActivities(CONTACTID, ACTIVITY, ACTIVITYDATE) VALUES (1, 'opt-in', '1/22/20'), (1, 'purchase', '1/23/20'), (2, 'opt-in', '1/25/20'), (3, 'deleted', '1/27/20'), (2, 'purchase', '1/27/20'), (1, 'purchase', '1/28/20'), (2, 'deleted', '2/26/20');

| How to map a class A that inherits from base class using AutoMapper in c# Posted: 22 Jun 2022 10:33 AM PDT I have a class GetData public class GetData { public FooClass PrevData {get;set;} public FooClass NewData {get;set;} } public class FooClass: Class B{} public class B { public string varC; public string varD; public string varE; }
I need to use automapper to map class GetData's PrevDataA's fields to Class C's properties. I will then use class C to store data in database. public class C { public Data data {get;set;} public string var_e; } public class Data { public string var_c; public string var_d; }
I have tried these two : CreateMap<GetData,C>() .ConvertUsing(src => src.PrevData.Select (x => new C { var_e = x.varE; varData= new Data() { var_c = varC; var_d = varD; }})); }
Here I get an error on 'select' that testClass does not contain definition for 'Select'. Also, I have tried using below: .ForMember(dest => dest.Data.var_c, src => src.MapFrom(src.PrevData.VarC))
This is also giving an error saying : Expression "dest => dest.Data.var_C" must resolve top level member and not any child's properties. You can Forpath, a custom resolver on the childtype or the AfterMap option instead.
Can anyone help in using ForPath or this. |

| GraphQL: making use of it to handle complex view/UI logic Posted: 22 Jun 2022 10:34 AM PDT I've got a requirement to move complex switches logic from UI layer to GraphQL layer. This complex switches logic is to perform a computation based on a bunch of backend configurations to determine whether a set of UI components should be shown or hidden. To show or hide a particular UI component in the set, it requires at least 3 levels deep of nested if-else branches logic. I'm currently thinking of adding the following type to the schema to solve this problem: type MyComplexView { componentAShown: Boolean! componentBShown: Boolean! # ... (gazzillion of other components here) componentXShown: Boolean! }
...and then I'd expect the data returned from the query would look something like: { "data": { "myComplexView": { "componentAShown": true, "componentBShown": false, // ... (gazzillion of other components here) "componentXShown": true, } } }
But it just doesn't feel right, and it feels like I'm abusing the GraphQL layer for doing this kind of job. So question is, is this also a valid use case for making use of GraphQL? Is there an alternative or better way of doing it? The idea is to share the complex switches logic for all the clients (e.g. web and mobile) that are going to consume the API without re-writing/duplicating the logic again on the client-side. |
| Unable to read Landsat 5 metadata using readMeta() of R Posted: 22 Jun 2022 10:34 AM PDT I am following a tutorial on remote sensing using R. The tutorial is available from here. pg 44. I would like to read the metadata for a Landsat 5 image, specifically for 1984-06-22 path/row 170/072. The Landsat Product ID is LT05_L2SP_170072_19840622_20200918_02_T1. Here is the L5 metadata. I am using the readMeta function from the RSToolbox package. The work should be pretty straightforward in that I put in the path to my metadata file and specify raw = F so that the metadata can be put in a format for further analyses. mtl <- readMeta(file = ".", raw = F)
After doing this (reading the L5 using readMeta) I get this error. Error in `.rowNamesDF<-`(x, value = value) : invalid 'row.names' length
Now of course there are many ways of killing a rat, so I used this method here - whereby read.delim function is used to read the metadata file. This brings in a dataframe with all the metadata values alright. However, when this dataframe is put into the radCor function in order to convert the L5 DNs to Top-of-Atmosphere radiance, the following error appears: Error in radCor(june_landsat2, metaData = metadata_june, method = "rad") : metaData must be a path to the MTL file or an ImageMetaData object (see readMeta)
Seems like radCor will accept nothing else apart from what is read by readMeta or the path to the MTL file itself. Not even the result from read.delim will do. Because the first error readMeta mentioned row.names length issue, I thought deleting the last row without a value in the metadata file would solve the issue, but this brings more complicated errors. In short, I would like to find a way to make readMeta read my L5 metadata file, since the result from readMeta is being used in other places of the tutorial. Thanks |

| Need to handle uncaught exception and send log file Posted: 22 Jun 2022 10:34 AM PDT When my app creates an unhandled exception, rather than simply terminating, I'd like to first give the user an opportunity to send a log file. I realize that doing more work after getting a random exception is risky but, hey, the worst is the app finishes crashing and the log file doesn't get sent. This is turning out to be trickier than I expected :) What works: (1) trapping the uncaught exception, (2) extracting log info and writing to a file. What doesn't work yet: (3) starting an activity to send email. Ultimately, I'll have yet another activity to ask the user's permission. If I get the email activity working, I don't expect much trouble for the other. The crux of the problem is that the unhandled exception is caught in my Application class. Since that isn't an Activity, it's not obvious how to start an activity with Intent.ACTION_SEND. That is, normally to start an activity one calls startActivity and resumes with onActivityResult. These methods are supported by Activity but not by Application. Any suggestions on how to do this? Here are some code snips as a starting guide: public class MyApplication extends Application { defaultUncaughtHandler = Thread.getDefaultUncaughtExceptionHandler(); public void onCreate () { Thread.setDefaultUncaughtExceptionHandler (new Thread.UncaughtExceptionHandler() { @Override public void uncaughtException (Thread thread, Throwable e) { handleUncaughtException (thread, e); } }); } private void handleUncaughtException (Thread thread, Throwable e) { String fullFileName = extractLogToFile(); // code not shown // The following shows what I'd like, though it won't work like this. Intent intent = new Intent (Intent.ACTION_SEND); intent.setType ("plain/text"); intent.putExtra (Intent.EXTRA_EMAIL, new String[] {"me@mydomain.example"}); intent.putExtra (Intent.EXTRA_SUBJECT, "log file"); intent.putExtra (Intent.EXTRA_STREAM, Uri.parse ("file://" + fullFileName)); startActivityForResult (intent, ACTIVITY_REQUEST_SEND_LOG); } public void onActivityResult (int requestCode, int resultCode, Intent data) { if (requestCode == ACTIVITY_REQUEST_SEND_LOG) System.exit(1); } }
