...ANSWER
Answered 2021-Mar-28 at 11:03Due to the leading /
in mv $i /Controllers/
you move every $i
to the very same directory, that is a directory named Controllers
on the very top of your filesystem.
Either cd
into each directory and use a relative path (cd "$i/.."; mv "$i" Controllers; cd -
) or modify the paths using bash's parameter expansion:
QUESTION
I am wondering if this is a bad practice. Is there any performance cost to decouple hosting service from the vendor for other infrastructures?
...ANSWER
Answered 2021-Feb-22 at 15:52Remember, with Jamstack, your client browser is making calls to APIs for dynamic content, not a single call to a server that is rendering your pages. The paths between browser and static content and browser and APIs is what matters for performance, not between content host and API. There's no call there, at least at runtime. From this perspective, I don't think there's a run-time performance cost worth worrying about. There may be other benefits to going with a single vendor when it comes to management, $ cost, etc. I'd worry about those until I had a reason to worry about run-time performance.

Thank you for taking the time to read my question! Most likely I formulated my question wrong, so sorry for confusing you already. It also might be a basic Javascript question for some of you, but I can not wrap my head around it. I will try my best explaining as to what I am doing.
My data looks like this:

I tried to follow Using DynamoDB with Custom Alexa Skills - Dabble Lab #226 - YouTube video, had some issues that mostly I was able to fix. I guess I am just to new to AWS and Lambda. But I wonder if someone is able to explain me why I don't have CloudWatch Logs as target, as shown in the video and how I can fix that. When I try to save a movietitle alexa sais 'we cannot save your movie right now. Try again!'. Would be amazing If someone here could help me : )

...ANSWER
Answered 2021-Jan-03 at 14:05As far as I understand you are missing the lambda logs in cloudwatch. So for them to enable you need to have an IAM Role with managed polciy AWSLambdaBasicExecutionRole.
That gives following permissions to lambda to log to cloudwatch:
QUESTION
I have an Express application with one endpoint, it takes a string from request, sends a request with this string to a different server and returns response. It's able to handle some load pretty well, but once I start cranking it up latency starts growing uncontrollably and ruins entire application. Below you can find sample graph, first I try to go with 60k requests per minute, then I do just about 5k and it's perfectly smooth both in throughput and latency.
I tried using both built in https
module and axios
library, both give exact same results.
Is there some setting I'm missing? Like max concurrent requests or something like that. I'm not too experienced with Node, so a bit confused by what I'm seeing, especially since it's reproduced on completely different infrastructures and at the same time a Java application on same infrastructures is able to do about 100k a minute without any issues.
Here's sample code that I use to send requests:
...ANSWER
Answered 2020-Dec-01 at 04:58The culprit here looks to be your system running out of available file descriptors (the sporadic DNS lookup failures are a common symptom of this). Since you've ruled out Express being related, I suspect this is due to the concurrent outbound requests being made: each outbound API call is going to open up a socket to the remote server (and the default file descriptor limit is usually 1000).
The fix depends on your exact OS, but on a typical Unix system, you can check your available file descriptors for user processes with:

I have this .txt with some logs* I'm trying to assign the value "-" to "user_name" in case the file has no user name. But, in those cases the output dict shows this "user_name":"". Do you know what I'm doing wrong? I also tried with item.groupdict["user_name"] = "-", but clearly this is not the root of the problem...
...ANSWER
Answered 2020-Nov-02 at 08:05You could either save item.groupdict()
in a variable and modify its content before appending it to logs
QUESTION
Hi I have created self mutating CDK pipeline for my infrastructure deployment.
I have added different application stages to this pipeline like Deploy to DEV, Deploy to UAT, Deploy to PROD Pipeline is working as expected and deploying changes to DEV -> UAT -> PROD environment but before deploying to UAT and PROD I would like to have manual Approval action so that changes will not deploy automatically to UAT and PROD there has to be manual approval action button after that button click changes should get promoted to higher environment.
I can find that option in code pipeline but I couldn't find such option in CdkPipeline construct.
Here is sample code -
...ANSWER
Answered 2020-Sep-28 at 01:27I found the answer in AWS documentation.
Every application stage added by addApplicationStage() leads to the addition of an individual pipeline stage, which is returned by the addApplicationStage() call. This stage is represented by the CdkStage construct. You can add more actions to the stage by calling its addActions() method. For example:

QUESTION
From what I understood in Clean Architecture, the objects in the Interface Adapters layer adapts the application's core to possible different infrastructures. That way the application's core can take input from different sources, like HTTP requests and console commands.
Generally a Controller
takes the input and a Presenter
gives the output, since the Controller is an adapter, it may be required to transform the given input to a different format accepted by the Use Case Interactor
. In this case, what happens when the Controller gets a bad input? How can it tell the client that an error happened, since the output is given by the Presenter?
EDIT:
Thinking better, the Controller
should not care whether the input is valid or not, It should try to always convert the input, even if it's needed to convert an invalid input to another invalid input. The UseCaseInteractor
should always return a meaningful response, it should not propagate exceptions to the caller. So when the Controller
gets bad input, it simply sends bad input to the called interactors, which can then properly handle bad inputs (it's application logic) and present error message through its presenters. For the Controllers input is input, its job is to adapt at best, am I right?
ANSWER
Answered 2020-Sep-14 at 04:06You got it in your "edit". The actual input validation should happen on the business logic, in the use case interactor. The controller does the "simple" data transformation.
Example: The view sends a date string. The controller tries to convert it into a Date object. In case the input string is not a valid date format the controller passes this information to the use case interactor e.g. as null or as option in functional languages or as any other type which makes it clear to the use case interactor that the input date was invalid. The use case interactor then decides how to handle this input.
QUESTION
I try to separate type bound procedure from the type definition in separate files. But I failed. Here are the codes.
The main program is as follows,
...ANSWER
Answered 2020-Aug-25 at 09:42The interface block declares an external procedure (a procedure that is not intrinsic and is not defined in a module). The subroutine subprogram in the module funcs_mod defines a module procedure. Those two types of procedure are not the same thing.
You don't provide a definition of an external procedure to the Fortran processor, so it complains.
Either move the procedure definition out of the module (make it a subroutine program unit), or use a separate module procedure and define the procedure in a submodule.
