Surprisingly, this is not undefined behavior.

Static initialization [basic.start.static]

Constant initialization is performed if a variable or temporary object with static or thread storage duration is constant-initialized. If constant initialization is not performed, a variable with static storage duration or thread storage duration is zero-initialized. Together, zero-initialization and constant initialization are called static initialization; all other initialization is dynamic initialization. All static initialization strongly happens before any dynamic initialization.

Important parts bold-faced. "Static initialization" includes global variable initialization, "static storage duration" includes global variables, and the above clause is applicable here:

Multiple requests causing program to crash (using BeautifulSoup)

Asked 2021-Jun-15 at 19:45

I am writing a program in python to have a user input multiple websites then request and scrape those websites for their titles and output it. However, when the program surpasses 8 websites the program crashes every time. I am not sure if it is a memory problem, but I have been looking all over and can't find any one who has had the same problem. The code is below (I added 9 lists so all you have to do is copy and paste the code to see the issue).

I was trying to create a thread safe queue, but something went wrong. I can't understand why does my thread freeze. Expected: 1 2 3, but i get nothing (everything just freezes)

I guess the problem is misuse of condition variable in front (pop) and get (peek) methods, but I can't find my mistake. Could you please point out my mistake and explain what the mistake is?

JdbcCursorItemReader uses a JDBC cursor (java.sql.ResultSet) to stream results from the database and is not thread-safe.

How Do I Center Product Title And Pricing Info On My Shopify Website?

I'm trying to figure out how to center the title of the product I'm selling on my website (Safe Guard Lenz) as well as center the pricing details that's under the product title as well. I need them centered for both mobile and desktop.

It's located at the bottom of the home page and on the product page itself. Ideally would want it centered for both.

Any help to achieve this would be greatly appreciated as I've been looking for a solution for this online and can't seem to have any success.

Module searching for str in text box accepts any match

Asked 2021-Jun-15 at 04:11

The following is code which searches a text box, seperates the 4 characters into their respective variables and checks the variable for a match but the error is in the line "If str(user_text) == str(B):" (Line 17). It is never true although it should be, if the == is changed to "in" it allows any amount of the match which isn't safe for the app i'm designing as it would allow anyone to access the account. Any way to help fix this??

The problem is that when you use readline() function while reading the lines of your file, it adds a \n at the end of the string (check reference), so as you mentioned, you never get found to be True.

An easy solution could be replacing the \n with blank like this:

QUESTION

Laravel relationships, Many to Many or Has Many Through?

Asked 2021-Jun-14 at 23:46

I'm building a web app using Laravel 8 and one thing I tend to struggle with is the complex relationships and accessing the data. I've started reading on hasManyThrough relationships but I'm not convinced that's the correct way to do it for my scenario.

The app is used by travelling salesmen to check in to a location when they arrive safely.

I have three main tables:

Locations (where they are visiting),
Checkins (where their check in data is stored, e.g. time),
Users

This is where it gets a little complex and where I find myself not being able to see the wood for the trees...

Locations have many users, users have many locations. Many-to-many pivot table created.
Locations have many check ins, check ins have many locations. Many-to-many pivot table created.
Check ins have many users, users have many check ins. Many-to-many pivot table created.

As such they're all created using a belongsToMany relationship.

Now what I'd like to do is access the user of the check in so I can call something similar to on my show.blade.php:

...

ANSWER

Answered 2021-Jun-14 at 23:46

You said "Check ins have many users", you seem to want the singular user for a check-in, but currently that would result in many users. It sounds like users check-in in a many to one relationship

Also $checkin->created_at will be by default a carbon object, so you can just go $checkin->created_at->format('jS F Y')

Also don't mix using compact and with, stay consistent and use only 1 as they achieve the same thing

Also $checkin->users()->name won't work, if you use the brackets on syntax is only returns a query builder instance, which you would need to call get on like $checkin->users()->get(), or you could use $checkin->users which will fetch them anyway. You may want to look into using with('relation') on query builder instances to stop N+1 queries if you want to dive a little deeper. Lastly $checkin->users()->get()->name also won't work as your user relation is many to many which returns a collection, which again points to you should have a belongsTo relationship called user without a pivot table
