useful for say, laravel components, where often text can be handed by mistake e.g.

With JSON schemas, if you want the schema to fail validation if it finds any additional fields you can just throw an "additionalProperties": false on the schema and call it a day, a bit like this:

Hey,

I would like to start a small website that will be entirely handled in Python. I will be using the Flask framework for this. So far I had a lot of contact with AWS ECS and ELB service, but I admit, Python itself is still unknown to me. That's why I have a few questions:

1. I understand that from the point of view of a software engineer it is better to separate the backend and frontend - so it is best to create two separate Python projects based on Flask - one will be the API, the other the frontend, right? Generally, both should be separate services in the ECS service I guess.

2. In such configuration do they both have to use some kind of WSGI server, like gunicorn? Is this a good solution to run inside Fargate with multiple vCPU?

3. There are quite a few questions and myths around Nginx for this solution. Until now I assumed that if I use Application Load Balancer it should be enough (after all it also acts as reverse proxy). Is it necessary to use Nginx as a sidecar in ECS, are there any benefits of this? Assuming that using Nginx would be advisable, should it be only for the frontend or also for API?

Thank you really in advance for any supportive advice here - I know that I have asked for a lot of things.

I am trying to insert values from a temporary table (NewThings) with columns Thing and Counts into my main table (MyThings) with columns Thing and Count. If a thing does not exist in the main table I want to insert a new row, otherwise I want to add to the counter. However, I am struggling with the correct syntax on the update statement. This is what I would like to do:

I am getting this error:

I recently migrate from Delph 10.2 to Delphi 11. Base of this code I get http from server periodically inside thread.

I have an application that extends over 3 crates: A crate that holds the abstract framework, another that holds one of a number of plugins selected as a cargo feature, and a third that contains a concrete implementation.

The problem is that the plugin determines the "Version" type throughout the application, and the implementation determines the Errors type throughout the application. To make the application plug-able across multiple plug-ins and across multiple implementations, I need the Errors type in the plugin to be generic, and I can't figure out how to do that.

In the minimal code below, I have hard coded the Plugin type Errors = MyThingErrors to show something that works. But I need the type of Errors here to be generic, not concrete. I've tried all sorts of combinations of generic parameters, but can't get it to compile.

So, is there a trick? Am I pushing Rust generics too far? Is this a Problem XY example, Perhaps I should follow a different approach?

Any suggestions gratefully received.

Here is the working example:

I am working with legacy C code and the new code is written in C++. To use the C++ standard library, I wrote a simple Iterator for the legacy LinkedList as shown below after reading through Bjarne Stroustrup's blog post on Adaptation.

My question is:

1. I want to create another Iterator for another struct say struct TokenList. I am not sure how to use namespace and still be able to use the range-based for loops. Any pointers would be helpful.

2. Are the adapters for the Iterator namely: begin, end, ++, *, != correct? Currently, I'm an interested in reading the contents of the LinkedList using range-based for loops.
