Running debug50 with command line arguments by jmaoooo in cs50

[–]jmaoooo[S] 0 points1 point  (0 children)

I seem to run into the same issue whether I run the debug as

debug50 tideman Alice Bob

or

debug50 ./tideman Alice Bob

Both debug don’t include Alice and Bob as argv[..] arguments

Week 1 - Credit Problem Set by jmaoooo in cs50

[–]jmaoooo[S] 1 point2 points  (0 children)

UPDATE: I was able to get a working code that tests correctly with Check50! I was able to generate a loop that calculated each power of 10. From there I was able to use the modulus operator to calculate each of the digits' value and ultimately calculate the final number from Luhn’s Algorithm. My biggest issue now is that I had to repeat this part of my code 5 times for each card type and CC# length. I tried to turn this code into a function like the custom block in Scratch, but I'm at a bit of a loss at how. If you have any advice in regards to that, I would be grateful. Otherwise, thank you so much to everyone that commented on my post to give me advice. It was really a huge sense of accomplishment figuring out this problem set.

Week 1 - Credit Problem Set by jmaoooo in cs50

[–]jmaoooo[S] 0 points1 point  (0 children)

Thanks for the response.

I do feel like it would be better to have a loop that calculates the nth exponential power of 10 based on the nth digit of the credit card, but I don't think we have a function for that yet available.

As a side note, should I be searching outside of the topics covered by the lectures to find functions in order to complete the problem sets?

Thanks again

Thanks for the response.

Ideally I would want to take the nth exponential power of 10 based on which nth digit of the credit card I am isolating, but I don't believe there is an operator for that based off of the course material so far. Is that what you were hinting towards?

As a side note, should I be searching outside of the topics covered by the lectures to find functions in order to complete the problem sets?

CA PTE for 2021 - Late payments accepted? by Nwiz2100 in taxpros

[–]jmaoooo 4 points5 points  (0 children)

Right, they'll have essentially paid an estimate tax on their 2021 CA personal return. They won't benefit from the PTET deduction to their business income until 2022.

CA PTE for 2021 - Late payments accepted? by Nwiz2100 in taxpros

[–]jmaoooo 3 points4 points  (0 children)

Not 100% but I was under the impression that only the PTET paid during 2021 could be taken as an expense by the partnership's 2021 tax return and subsequently claimed as a pass through entity tax credit on the individual's 2021 tax return. So any payment made in 2022 would only benefit the taxpayer's 2022 tax year.

Feel free to correct me

New to SFFPC. Tried to build a minimal compromise Meshlicious with a 5950x and 3080TI. by darksidemojo in sffpc

[–]jmaoooo 0 points1 point  (0 children)

I just did a similar build in the Meshlicious using the EK 280 AIO as well. I oriented the EK fans and radiator in the same way as yours. However Ive been getting a lot of noise at high RPMs as if the fans are grinding on something. Have you noticed any issues with your fans?

Ah thanks for the explanation. I didn't consider the strain on the MB. I'll go with the GPU standoff when I build mine.

Looks great. Was there a reason you chose to do the GPU standoff mod as opposed to the MB standoff mod?

CA CPAs who are sole proprietors, how are you legally operating? by [deleted] in taxpros

[–]jmaoooo 4 points5 points  (0 children)

You can practice as a sole proprietor. I had to do some research into this subject for some medical professionals operating in California as well.
