I'm normally OK on the joining and appending front, but this one has got me stumped.

I've got one dataframe with only one row in it. I have another with multiple rows. I want to append the value from one of the columns of my first dataframe to every row of my second.

df1:

df2:

Output I'm seeking:

df2

I figured that this was along the right lines, but it listed out NaN for all rows:

I'm trying to create a Windows form via Powershell and I need to capture the file path and store it in a variable. After the user clicks the 'Select' button and chooses the file, I would like to store the file path in a variable. Can someone please help me with this? The part of the code that shows the file path is the $selectButton.Add_Click() method.

In C++20, we got the capability to sleep on atomic variables, waiting for their value to change. We do so by using the std::atomic::wait method.

Unfortunately, while wait has been standardized, wait_for and wait_until are not. Meaning that we cannot sleep on an atomic variable with a timeout.

Sleeping on an atomic variable is anyway implemented behind the scenes with WaitOnAddress on Windows and the futex system call on Linux.

Working around the above problem (no way to sleep on an atomic variable with a timeout), I could pass the memory address of an std::atomic to WaitOnAddress on Windows and it will (kinda) work with no UB, as the function gets void* as a parameter, and it's valid to cast std::atomic to void*

On Linux, it is unclear whether it's ok to mix std::atomic with futex. futex gets either a uint32_t* or a int32_t* (depending which manual you read), and casting std::atomic to u/int* is UB. On the other hand, the manual says

I'm creating an application where the user can post information and see the information posted, something like a forum. I created a list where the publications stored in the database are shown, so on the main page that list is shown with the title, description, date, etc. of each publication. Now, what I'm trying to do is select anyone of the posts in the list and then display the full information of the selected post in other view. I'm using a MVC view with its respective controller to consume the API.

I have to parse lists of names, addresses, etc. that were OCRed and have invalid/incorrect characters in them and on the state postal code I need to recognize the pattern with a 2 character state followed by a 5 digit postal code and replace any non numeric characters in the postal code. I might have OK 7-41.03 at the end of a string I need to remove the hyphen and period. I know that re.sub('[^0-9]+', '', '7-41.03') will remove the desired characters but I need it only replace characters in numbers when found at the end of the string and only if preceded by a two character state wrapped in spaces like OK. It seems if I add anything to the regular expression as far as a lookbehind expression then I can't seem to get the characters replaced. I've come up with the following but I think there must be a simpler expression to accomplish this. Example:

I'm writing a Firebase function (Gist) which

I have a small webpage that relies on splitting a textarea value by newlines. Is it OK to only use something like textarea.value.split("\n") or should I also do something with "\r" to make sure it works on all devices? Would it make any difference at all?
