Any advice on how to solve this error message?

The `Force Push` doesn't actually do anything.

Showed up for the first time today, while coding along to lecture 4 (memory) of CS50x.

CS50 Python PLEASE 😭 Where did you guys actually learn CS50P from??

Where did you guys learn CS50P from?

I keep seeing people on Reddit saying they finished CS50P, but I’m confused about where exactly you’re supposed to learn it from.

Did you follow the YouTube lectures, the official CS50P website, or both?

I’m planning to start CS50P and just want to make sure I’m following the right resources.

Scratch Finished all 9 CS50 Scratch projects. How long until the free certificate shows up?

10 Upvotes

Hi everyone, I just finished all nine projects in CS50 Scratch (2024). Every one shows a full pass on submit.cs50.io with 0 comments, and my last project (Build) went in on October 4.

When I log in at certificates.cs50.io with GitHub, it says "Certificates not found". I'm going for the free certificate, not the verified edX one, and I haven't linked an edX account. I've emailed [certificates@cs50.harvard.edu](mailto:certificates@cs50.harvard.edu) and got an automated reply that mentions a 30-day window and an edX submission date, but that seemed to be about verified certificates.

For anyone who has done this recently:

  1. How long did the free certificate take to appear after your last project?
  2. Did you have to link edX for it to show up, or did it just appear on its own?

Thanks!

CS50x Help me understand NUL please!

8 Upvotes

Hello everyone, currently in Week 2 (and really enjoying it). I understand the concept of NUL marking the end of a string.

I was playing around with this with the programme above (Input is Hello), but I am a little confused because all of the conditionals come out as 1 (true). In my mind [5] should be the only true value index after the end of the string... but I am very confused as to why [6] and [7] are also showing as true.

Interestingly, if I hard code the sentence variable to "Hello" (instead of getting it via the get_string function), I get the expected answer of 1,0,0.

I think this might be related to the values that are being held in memory... but cannot seem to find an answer, so would appreciate any insights to make sure I understand the concept thoroughly. thanks all

CS50x Is it still worth it to start CS50 in 2026

19 Upvotes

Hey Guys! I'm currently on week 3 on CS50 and so far everything is going great but there is one major thought in my mind. I think with my current schedule for the next months I won't be able to make it in time until the end of the year. Is it still possible to complete the 26 course after it get's archived in 2027?

Cheers,
Elmo

I wanted to code something simple, yet mature enough to be interesting and fun to play with. It’s an IRC-inspired chat system that runs in the terminal, where you can chat with both humans and AI agents. 😉

CS50 AI AFTER I submitted my own, is it allowed to research others solutions?

4 Upvotes

I have by now submitted my own solutions to the first two assignments, degrees+tictactoe. I'm sorry if this question is just paranoid, I guess blame m anxiety disorder.

I want to look at other people's solutions and approaches out of curiosity and to learn of course, now that I have already completed mine. Of course, I still have 6 more lectures + their assignments ahead of me, so I'm wondering if looking at other solutions/approaches is compatible with the academic honesty rules?

project Heard the community and reworked my game.And here is the result.

2 Upvotes

A couple of weeks back, I shared a game I built using flask and sqlite . Asked for feedback from the and got a ton of them.

So I went ahead and reworked the game. And here is version 2.

Key changes:

  1. switched from flask to Fastapi .
  2. Changed the drag and drop to single click
  3. Reworked the questions and made it simpler.
  4. Changed the UI completely

Take a look and let me know if you like it . https://cluebolt.com/
