In RAII(Resource Acquisition Is Initialization), an object obtain piece of resource is the procedure of initialization itself, and resource will be held as life cycle of object, but resource in string_view only includes char * and size, which means the address could be free to invalidation and object couldn't be conscious about it. And does it make the object never closure?

Last year, Chrome shipped a feature to increase battery life by limiting JavaScript timer wake ups in background webpages.

The task is to build an accurate price calculator which accounts for a sales price based on quantity. I've built a gross price calculator using compiledCart.reduce() method, (below) however I can't figure out how to add the sales functionality.

If the user buys 1 Candy, the price is $3.97, if the user buys 2, the price is $5.00. If the user buys 3, then first two are $5.00 and the 3rd is $3.97. Same thing if the user buys 5. The first 4 are $10 and the 5th one is $3.97

My compiledCart variable looks like this:

Today has been quite challenging so I can't think of any new ideas anymore so the solution to this question may be quite obvious to you. I have a very simple data frame like bellow:

I hope you're all doing well.

So I've been working with Excel my whole life and I'm now switching to Python & Pandas. The Learning curve is proving to be quite steep for me, so please bare with me.

Day after day it's getting better. I've already managed to aggregate values, input/ouput from csv/excel, drop "na" values and much more. However, I've stumbeled upon a wall to high for me to climb right now...

I created an extract of the dataframe I'm working with. You can download it here, so you can understand what I'll be writing about: https://filetransfer.io/data-package/pWE9L29S#link

I have a nested list of strings:

station_data = [['65.29', 3003', 'station1'], ['81.23', '8000', 'station2'], ['77.33', '3500', 'station3']] etc...

I am trying to type cast the first position [0] of each list from string to float

I am trying to type cast the second position [1] of each sub list from string to int

I have tried different for loops, but for the life of me I cannot seem to get the syntax right

station_data can be modified, or a new list can be created, fine either way.

Desired output should look like: station_data_processed = [[65.29, 3003, 'station1'], [81.23, 8000, 'station2'], [77.33, 3500, 'station3']]

Any suggestions are a huge help, thank you!

I can't for the life of me figure out how to make a variable in a json file increase, when a certain person reacts to a message in discord, that my bot sent (the reaction is already made by the discord bot if that matters).

As stated above. Under IIS Express on VS2019 I have no issues. When opening the site after deployment to Azure I get:

"The character encoding of the plain text document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the file needs to be declared in the transfer protocol or file needs to use a byte order mark as an encoding signature."

I initially tried adding every permutation of I found to no avail. Eventually I tracked the error down (by removing lines of code until the error no longer appeared) to firing when I tried to open a SqlConnection.

I've been using git my entire development life, and just recently got assigned to an antiquated sourcebase that is unfortunately still using IBM Clearcase for Windows for its version control. I've been struggling to get a grasp on the basics, mostly because there are many things that don't have a clear analog to git, and there isn't much support available for Clearcase since nearly every business no longer uses it.

My main problem is I can't figure out how to checkout a different branch. I've created a snapshot view of a VOB(so in git terms, a local repo cloned from a remote), and I believe I'm on the master branch. I'm looking at it in Rational ClearCase Explorer. I then open up the "Type Explorer", select the VOB I'm working with, and select "branch types". From here I can see every single branch that's been created.

Let's say I want to check out branch "my_branch". I don't see any appropriate selection from the context menu upon right-click in this Clearcase explorer. The only options are "Clone", "Delete", "Rename" and "Properties". From cleartool, I run the command
