QUESTION
for my college project, I am trying to implement a sectioned recyclerview with the section title as date, and a list of appointments as the contents, in each row of appointments I want to display some fields, in which I have created the apnmntDetails class as below:
...ANSWER
Answered 2021-Mar-04 at 08:40You should call sectionList.add(new Section(document.getString("date"),apnmntList)); inside onComplete() call back method. Because this is a call back method is suspended and control jumps to execute code after call back code block. One more thing you should initialize apnmntList before for loop, because new list has to be saved for each Section.
I have made changes to onComplete() method, just have a look :
QUESTION
few days ago I started working on the sleeping barber problem, got some issues with segmentation fault But they have been solved here
Even though I fixed the missing parts, I still have a problem. I need to use FIFO queue, and create shared memory for it. I get no errors when creating it. Running the client should let me put clientAmount of clients into the queue, from which barber should be getting them. Every client is described by his process id. But when I try to do so, client program shows that clients have been added to queue:
ANSWER
Answered 2021-Jan-24 at 13:01There are several mistakes in your program:
- In the client code, you are calling
sem_wait(pillow)andsem_post(pillow);, although the variablepillowhas not been initialized. This causes undefined behavior. In order to initialize a semaphore, you can use the functionssem_initorsem_open. - In the client code, you release the mutex
queueimmediately after acquiring it. Instead, you should only release it when you are finished with the queue operation. - In the client code, you call
push(waitroom, id)twice, the second call being immediately after the first call. This does not make sense. - In the barber's main loop, you are releasing the mutexes
queueandbarberwithout acquiring them beforehand, then acquire them afterwards. A mutex should normally first be acquired, then released, not the other way around. Usesem_waitfor acquiring the mutex,sem_postfor releasing it. EDIT: Meanwhile, I believe that you are using the semaphorebarberfor signalling purposes, not as a mutex. In that case, it is correct to callsem_postwithout having calledsem_waitbeforehand. - You are not checking the return value of
sem_wait. For example, it is possible that the function fails due to being interrupted by a signal handler. - It is not safe to use the function
printfin a signal handler. See this link for more information. - You are not waiting for the child processes to finish, before terminating the parent process.

QUESTION
I'm extremely new to html and css. My 6 year old recently decided he wants to become a barber, so I decided to use this as a chance to practice and create a mock business page for him.
I can't seem to get the background image to show up but the color works perfectly fine. I used the Inspect tool on Chrome and it says the image file wasn't found. This means the path is incorrect, right?
Image path: /Users/myname/Documents/CaydenCutz/img/barbershop.png
CSS file path:/Users/myname/Documents/CaydenCutz/CayStyleSheet.css

Answered 2019-Jul-31 at 04:06The value given to url() needs to be a URL that is resolvable relative to the CSS file, or an absolute URL (for example, an external URL). So, assume you have this structure:
- site root
- CSS folder
- styles.css
- img folder
- background.png
- CSS folder
Given that, for url() to find the file correctly, you would be able to use one of these:

I'm not a PHP/MySQL programmer, but I'm trying to help my friend that just opened his own barbershop by creating a very simple website for him. I added to the site a contact form that sends the info to a MySQL database. That part works perfectly. Now I'm tryin to display upcoming appointments by showing only the ones scheduled for the day.
...ANSWER
Answered 2019-Jul-22 at 23:11It's easier and more efficient to handle this filtering at the database level, its what they are designed for. Yours is quite a simple one, assuming your DB servers date is in the same time zone as your barbershop, or the offset for insertion and extraction are the same add a where clause to the query to only return appointments for today and due after the current time:
