QUESTION
Putting some finishing touches on a class assignment, but I'm running into problems with two concepts.
Here is the assignment: write a C# .NET Framework console application to demonstrate the use cases of properties in C#. The application will do the following to accomplish this goal.
Log every instance of writing of a private field within a property setter. Before the program exits, output the activity log to the screen. Set the value of each property of each student to facilitate testing and operation of this logging functionality.
Choose at least one property for students, and make sure its setter has logic in it other than the default auto property setter code. Logging is not counted for these requirements. See the WatchDogAbility example from Chapter 3 slides/text. Historically, systems have allowed students to restrict the viewing of their personal information. Implement this system here, by ensuring the getters of properties check for this value before returning student information. Student ID and Name are exempt from needing to be checked.
Submit a screenshot of you stopping your program in debug mode in Visual Studio. Set one of the Student object's properties. Pause on the line where the new value is written to the private field. Make sure the new value is shown on the screen in your image (see example below, using Alt + Print Screen). Output all data for all students, let’s say a minimum of 10 students, with at least one with restricted personal information.
I am lost as to how to "log every instance of writing of a private field within a property setter" and I am also confused as to how I can satisfy this requirement, "Historically, systems have allowed students to restrict the viewing of their personal information. Implement this system here, by ensuring the getters of properties check for this value before returning student information. Student ID and Name are exempt from needing to be checked."
Below is the code I have thus far:

QUESTION
I have an AWS SQS FIFO queue configured to deduplicate messages based on content. My rails app uses Shoryuken worker to get messages from SQS. Here is the worker code:
...ANSWER
Answered 2018-Dec-18 at 20:34Turns out, the problem was with the queue's VisibilityTimeout setting. By default it is set to 30 seconds, but often messages would arrive to the receiver side outside of the allowed 30 seconds, and this would mean that Shoryuken would fail to delete the received message from the queue with the following error:
ERROR: Could not delete 0, code: 'ReceiptHandleIsInvalid', message: 'The receipt handle has expired', sender_fault: true
The solution is to increase the VisibilityTimeout. I set it to the maximum allowed 12 hours, and that resolved the issue.
More about VisibilityTimeout: https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-visibility-timeout.html
The thread that put me on the right track: https://github.com/aws/aws-sdk-java/issues/705
QUESTION
I'm still learning about SQS, I did some successful tests with SQS and a Ruby application with Shoryuken that picks up the messages. This works fine. We want to get 1000 IoT devices installed in people's homes. These devices will send events to the backend, which will be picked up. So far so good.
Now we also need to send messages back to the devices (less frequent, but still). Will I be able to use SQS for this too? How can I target the device?
Do I need to add a MessageAttribute to identity the destination? Or create a queue per device?
What are the best practises here?
...ANSWER
Answered 2018-Nov-02 at 18:18SQS is definitely not the right tool to use for sending messages to individual devices, and while a queue per device may work, I would not recommend it (1000+ devices regularly polling for messages can get expensive).
Take a look at Amazon IoT, in particular the message broker component.

After upgrading from unicorn to puma, i've encounter a strange error;
Sometimes when worker are starting, they start on the bad ruby version, and so causes an error. It seems to be random...
This error causes 503 on my application because the worker is not starting properly.

QUESTION
I have an array of objects which holds data, which I output to the DOM using map. Each item in the list, has a @click event listener. When you click on one of the items, I want it to be highlighted by way of adding a css class, for example ‘hover’. So basically it should work like a menu system. When you click on an item, that item is highlighted and the others should not be highlighted and vice versa.
The way i have it set up right now, all of the items in the list get highlighted, which is not the logic i’m trying to do. I have used console.log, to display which item has been clicked. However, I still have not figured out, how to make that selected item, the one thats highlighted instead of the whole list?
...ANSWER
Answered 2018-May-24 at 16:36Put "active" as a property of each dragonBall fighter and turn it on if it's clicked and turn the rest off.
The concept of Vue is to play with the data and let Vue take care of the UI :)
OR
rename "active" to activeID and set the ID of the clicked item to activeID and then apply hover only if activeID == item.id

QUESTION
I am using rails "Shoryuken" gem but I am getting errors for validation on queues on my development environment when I started rails server below is the error:-
gems/shoryuken-2.0.11/lib/shoryuken/environment_loader.rb:172:in `validate_queues': The specified queue(s) ["development_worker"] do not exist (ArgumentError)
I have used below settings:-
config/shoryuken.yml
...ANSWER
Answered 2017-Aug-09 at 13:13Ravindra, looking at the code of shoryuken, you are getting the error because you do not have created an SQS queue named development_worker, is that rigth?
You will need to create one queue for each developer, because shoryuken will be running in the computers of each developer. If you don't do that, all shoryuken processes of each computer will be polling messages of the same queue.
Imagine that there are two shoryuken processes, sh1 and sh2, that correspond to the dev1 and dev2 machine respectively.
If the dev1 sends a SQS msg to the dev-queue, the sh2 proccess can be able to poll the message that the dev1 sent.
If you wish to avoid to create the queues in AWS, you can take a look at this.
QUESTION
In my Ruby on Rails application, I'm using shoryouken for background processing. I've many sqs queues (6-7) in my application. One of the queue has 2000-3000 jobs and it takes around 3 hours for the worker to process these 2-3k jobs with a default concurrency of 25. So based on what factors can we decide to increase the concurrency (which is the number of threads to process jobs). Please do comment if anything is unclear in the question.
...ANSWER
Answered 2017-Feb-14 at 07:49Three main factors are
- Number of Cores
- Type of Job - I/O or CPU bound
- Is there another application or process running on server
Ideally for a cpu bound task keep number of thread to number of cpu cores.
For I/O bound task it requires benchmarking and calculating wait time for an I/O, and then you can decide the optimal value. For rough estimate if you have 4 cores than for I/O bound task you must keep at max 8 threads.
If you have your rails app running on the same then you will need to reduce number of cores.
Increasing the number of cores will not increase your performance if your system doesnt support.
