16.04 – A volume has been detected with software packages. Would you like to open it with the package manager?

A newbie question.
I use Ubuntu14.04 on my desktop. I'm considering updating to 16.04, so I looked:

https://tutorials.ubuntu.com/tutorial/try-ubuntu-before-you-install#0

who referred me to:

https://tutorials.ubuntu.com/tutorial/tutorial-create-a-usb-stick-on-ubuntu#0

I downloaded an iso 16.04 file and then used Startup Disk Creation to create a bootable USB memory 16.04.

Halfway through the process I received a message.

"A volume has been detected with software packages.
Would you like to open it with the package manager? "

This worried me because I thought I could install 16.04 on my hard drive and not on the USB, so I aborted the process.

I will answer "yes install" 16.04 on my hard drive.

sql server – Service Broker error – Conversation manager not found

Everyone,

A new third-party application that uses Service Broker in SQL Server 2017 is causing the error log to report numerous failed delivery notifications due to conversation identifier not found. I made sure that the Service Broker is enabled from sys.service_queues and has restarted the Service Broker correctly, but the errors continue. These errors continue every two hours (Process of the application?). I have read that another option is to configure the database as reliable, which I have not tested at this time.

The required components of Service Broker are present, which I have checked through system tables such as message types, service contracts, service queues, services and endpoints. All queues have a status of "Not available" (query used in the example of dm_broker_queue_monitors).

There is no message in the sys.transmission_queue system table.

When consulting the system table sys.service_queues and all the rows have is_activation_enabled = 0, is_receive_enabled = 1, is_enqueue_enabled = 1, and is_poison_message_handling_enabled = 1. Could it be due to poisoned messages?

I know the basics when it comes to Service Broker, but this has perplexed me. Here are some questions I have:

Any other table or system query that I should use to further diagnose this problem?

It seems that the messages are stuck and can not be delivered. Any idea why this happens or what is causing this error?

Any possible solution to solve these errors?

Thanks for your time in advance!

fastboot – I can not unlock the boot manager in fly fron linux

My operating system is majaro linux.
My phone is fly nimbus 8.

I tried to unlock the boot loader on it.
I followed the instructions.
First I go to the Dev mod then enable Unlock OEM Y USB debugging.
Second I wrote:

adb devices

exit:

List of connected devices
56090913288827 device

Then I wrote:

adb reboot-bootloader

It was done like this:
enter the description of the image here

Then I checked again:

fastboot devices

exit:

56090913288827 fastboot

It seems that everything works well!
But then I went in:

sudo fastboot oem unlock

And then nothing. I do not mean absolutely nothing: it does not throw an error, it does not answer, it is not completed.
By the way, the phone does the same, absolutely nothing!
I already tried it ten times more but it does not want to work!

Does anyone know what the problem is?
Did anyone have the experience in flash the fly(in particular nimbus 8)?
I will be waiting for an answer!
Thank you!

Design patterns: How to apply OOP to real-world examples without putting all the logic in Manager classes?

Lately I am trying to implement a specific problem using an object-oriented approach. I receive the fundamental principles and their advantages, but I do not apply it to a problem in the real world. Most of the examples that one could find consist of Cats or Dogs being implementations of Animal. However, these do not give me enough understanding of how to model the problem below with respect to another frequent example: a school management system.

Imagine a school taking Students, The courses, TeachersY Notes.
My implementation would be something like this:

class person {
name of the chain;
int age

Person (name of the chain, int age) {
this.name = name;
this.age = age;
}
}

Student class extends Persona {
double gpa;

Student (name of the chain, intimate age) {
super (name, age);
}
}

teacher class extends person {
string roomNumber;

Teacher (chain name, int age, string room number) {
super (name, age);
this.roomNumber = roomNumber;
}
}

class course {
name of the chain;
Teacher professor
Students[] student;

Course (name of the chain, teacher professor) {
this.name = name;
this.professor = professor;
this.students = new student[];
}

registered student (student student)
students.add (student);
}
}

Class note {
Course course
Student student
double value;

Note (course, student student, double value) {
this.course = course;
this.student = student;
this.value = value;
}
}

Now him student has a lot of Notes And we want to calculate your GPA. This could be a simple average of your NotesValues ​​or more complex logic using weights and / or ignoring optional courses.

Now my question is: Where do we put this logic? Ideally, it would have a function. double calculateGpa () in student so you can call student.calculateGpa (), but having this logic in student would do break the SRP in my opinion. Nor does it belong to any other class listed here. A class called GpaCalculator or NotesManager It would be another conjecture, but it seems too much like moving all the logic of the domain to classes that do not represent a real object but only actions (see also this answer).

If that is the way to go, why would not I write a pure, static and stateless function in a class called NotesHelper? Creating an administrator class to have only one function calculate double (), and using its instance instead of a static function seems to make it look like OOP while in reality it is not. I feel there should be a better approach, probably one that I did not think about, or maybe I'm wrong here. Could you give me some advice?

Thank you!

Do you have to make the icon disappear until you have new available updates, not only any updates available.
