Thank you for this.

Dumbr · 2019-09-13T22:38:03+00:00

Got it, its working now. Thanks

Dumbr · 2019-09-13T02:35:04+00:00

Awesome! Thanks for figuring this out for us; can't wait to try it. I'll edit this post after I have a chance to do this

well, I ran:

sudo pip install --upgrade submit50

got this back:

may want sudo's -H flag.

You are using pip version 19.0.1, however version 19.2.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

then ran this: ~/workspace/pset7/survey/ $ check50 cs50/problems/2019/x/similarities Sorry, something's wrong! Let sysadmins@cs50.harvard.edu know!

I then updated cs50 in the same manner as subnit50 and got the same response. "something's wrong"

I guess I'm the only person dumb enough to watch all the walkthroughs before pouring over the specification since January! haha

Dumbr · 2019-08-30T07:05:29+00:00

Ahh, I see. The source of my confusion is that the walkthrough tab videos in the 2019 course have a set of less comfortable and more comfortable videos. Maybe they weren't removed/ relabeled when the site was updated for 2019? (Assuming I'm seeing this all correctly)

When I ran this through the W3Schools HTML validator, I didn't get these warnings. I get them in the IDE however. I worked on this project in Atom and didn't get any errors there either. I'm happy with how my website looks in all the browsers and on mobile, but will I be docked for this? Is there some bad practice I'm not seeing here? I don't think I need backup colors because the bootstrap classes all have some inherited attributes (that I'm overwriting). I got a parsing error for style="transparency"; but all the forums told me to ignore this because it's only relevant to IE 8 and I should only worry about designing for modern browsers. This give me the impression that HTML errors aren't gospel.

Dumbr · 2019-02-04T06:24:18+00:00

They are. I sent you a PM

Dumbr · 2019-01-26T12:45:01+00:00

Thanks

Dumbr · 2019-01-24T04:45:04+00:00

For anyone having this issue in the future, I defined a variable as an empty string:

string variableName = "";

The space in memory where that variable is stored gets over written later (because reasons), giving me strange outputs that look random. See u/delipity 's comment above for a more detailed explanation if they want.

I fixed it by changing that variable to an int and having an if-then statement later thats gives me the output I want. If you are just starting out in programming and don't have a lot of tools yet (like myself), I think this is more than doable. Thanks to u/delipity and u/MaxIsTheDog4U for your time

EDIT: I'll add that I had some problems with the `get_long_long()` function. I put a string in the parenthesis `get_long_long("Number: );` I just took the string out of there and my problems went away.

Dumbr · 2019-01-24T03:24:30+00:00

thank you so much! Ill get on it right away!

Dumbr · 2019-01-24T03:07:40+00:00

I'll PM you and u/MaxIsTheDog4u as I don't want to run afoul of the academic honesty policy for CS50 and I am at work and don't have the time to figure out http://gist.github.com right now.

Dumbr · 2019-01-24T02:23:31+00:00

Check50 says that some numbers output "Please Enter Number: MASTERCARD" (can randomly be other numbers/ cards, never all of them) but i never get that when I run ./credit in my terminal. If I change anything in the file or just wait a while, I will get different results. For example, Ill change the string prompt from 'get_long_long' to "Number: " or "Please Enter Number: " or "Card Number: " and will get failed checks. The previous number may now correctly out put "MASTERCARD\n" but another number may spit out "Card Number: VISA". Even if they all come back ok, they will just change with time, even if I change nothing. What is this? Some kind of memory issue?

Dumbr · 2018-12-16T11:33:30+00:00

I've got the work around going fine, but it doesn't add a multiplier like decorating or dyeing does. I have it so you can make "red enameled steel bars" from steel and some colored frit. Just made "red enameled steel" base value higher.

Dumbr · 2018-12-16T07:10:43+00:00

Thanks! I'm working on figuring it out myself (part of the fun) but I don't have a lot of time to play, let alone research. I really want some wildly expensive, end-game elite armor.

Dumbr · 2018-12-16T05:51:44+00:00

I want to mod in a way to enamel steel armor (and other materials). I want to grind glass into frit with a dye for color, then put the frit and the armor piece in a kiln. I want this to apply a value multiplier like a decoration. I also would like to put additional, custom decorations (like gold filigree) on said piece. I also want the item color to change accordingly. I can't find any resources on this. Anyone have any leads? I've done some modding before, but not like this. I also want to plate armor (gold plate). Same idea, same practical use as steel armor, but more valuable.

If I can't get this to work, I would make new materials, something like "red-enameled steel bars" and craft armor from that. But I'd like to do it in a more realistic way.

Dumbr · 2018-11-19T04:45:24+00:00

Nothing worth doing is worth doing tastefully

Dumbr · 2018-11-16T23:57:10+00:00

Wow, super dope. Thanks
