QUESTION
I'm currently using Winsock2 to be able to test a connection to multiple local telnet servers, but if the server connection fails, the default Winsock client takes forever to timeout.
I've seen from other posts that select() can set a timeout for the connection part, and that setsockopt() with timeval can timeout the receiving portion of the code, but I have no idea how to implement either. Pieces of code that I've copy/pasted from other answers always seem to fail for me.
How would I use both of these functions in the default client code? Or, if it isn't possible to use those functions in the default client code, can someone give me some pointers on how to use those functions correctly?

select()can set a timeout for the connection part.
Yes, but only if you put the socket into non-blocking mode before calling connect(), so that connect() exits immediately and then the code can use select() to wait for the socket to report when the connect operation has finished. But the code shown is not doing that.
setsockopt()withtimevalcan timeout the receiving portion of the code
Yes, though select() can also be used to timeout a read operation, as well. Simply call select() first, and then call recv() only if select() reports that the socket is readable (has pending data to read).
Try something like this:

I'm trying to help a developer who is trying to harden a web server against server-side request forgery. In short, I've wrote a script that sends a "forged" HTTP request which we will use to test against the server until it is configured to not respond to such manipulated requests. I'm getting an error on Invoke-WebRequest: "Cannot validate argument on parameter 'Uri'" and while I've tried a ton of different combos of the below code I cannot get it to fly. Any thoughts? (Note: my-ef.example.com below is not the actual host)

QUESTION
I want to collect the names (Jenny, Tiffany, etc.) that are stored in every object. and these objects live in an array. I've used Array.prototype.every() and Array.prototype.forEach(), but I don't think they are the right methods.
I also want to note that majority of these codes are from Codaffection. I am practicing on developing in React.
If you would like to experiment with the code, click here.
In every object, there is an id, fullname, email and etc.
This is the code that adds, edits, generates unique ids for each employee, and gets all storage data.

I am querying a database for an item using R2DBC and Spring Integration. I want to extend the transaction boundary a bit to include a handler - if the handler fails I want to roll back the database operation. But I'm having difficulty even establishing transactionality explicitly in my integration flow. The flow is defined as

Answered 2021-Jun-15 at 18:32Well, it's indeed not possible that declarative way since we don't have hook for injecting to the reactive type in the middle on that level.
Try to look into a TransactionalOperator and its usage from the Java DSL's fluxTransform():

QUESTION
I've read a number of questions on this same error but couldn't understand whats happening in my case. On the other questions this error is caused by an object being used as a React child or caused by more than one prop attribute being passed.
I'm trying to set formik and yup to validate a Day Field according to a Month Field, both using react-select, in such way that if the month is February then the max day allowed is 29. Just that...
I've managed to reproduce the error in a Codesandbox: https://codesandbox.io/s/formik-yup-reactselect-rmd9f?file=/src/App.js
If you select the Day 29 and any month, then it works, but if you select day 30 and February then this error appears and I can't find out what's wrong:
Uncaught Error: Objects are not valid as a React child (found: object with keys {value}). If you meant to render a collection of children, use an array instead.

QUESTION
I want to use firebase auth for my android and ios applications with custom backend. So I need some way of authentication for api calls from mobile apps to the backend.
I was able to find following guide in firebase documentation which suggests to sent firebase id token to my backend and validate it there with firebase Admin SDK. https://firebase.google.com/docs/auth/admin/verify-id-tokens
But this approach does not seem to be a security best practice. For example here https://auth0.com/blog/why-should-use-accesstokens-to-secure-an-api/ it is said that for API access one should use access tokens rather than id tokens.
Are there any good pattern for using firebase auth with my backend?
...ANSWER
Answered 2021-Jun-15 at 15:02firebaser here
Firebase itself passes the ID token with each request, and then uses that on the server to identify the user and to determine whether they're authorized to perform the operation. This is a common (I'd even say idiomatic) approach to authentication and authorization, and if there's a security risk that you've identified in it, we'd love to hear about it on https://www.google.com/about/appsecurity/
From reading the blog post it seems the author is making a distinction between authentication (the user proving their identify) and authorization (them getting access to certain resources based on that identity), but it'd probably be best to ask the author for more information on why that would preclude passing an ID token to identify the user.

QUESTION
This question is related to Azure MSIX Build and Package task only has Release and Debug configurations
We have a WinForms project that has an MSIX installer. Manually, we can successfully create
- An MSIXBUNDLE and deploy it to Kudu
- An MSIX and deploy it to an Azure VM through a VHDX. We have manually convert the MSIX to a VHDX first
We are now trying to automate the build and release process to create the VHDX. However, we are getting a blank screen when the VHDX is mounted using a process that we have already validated. The only thing different is the build method (i.e., MSBuild versus VS Publish).
How do we create a working VHDX in Azure CI Build Pipeline?
Below is the YAML.
...ANSWER
Answered 2021-Jun-15 at 14:26Actually, there is nothing wrong with the YAML. The problem was a delay in the virtual machine loading the VHDX. In other words, wait about 5 minutes once the VHDX is mounted before trying to run the application. I am leaving this here in case anyone else runs into this issue.
