In the words of the late John F. Kennedy: "We choose to do things not because they are useful, but because they are excuses to vibecode another Codeforces extension". People were confused when he said this because they didn't know what "Codeforces" meant. The Soviets interpreted it as a subtle threat about American capabilities in the yet uncharted field of cyberwarfare. But I digress.

There's no need to make 998244353 extensions to do things that you can do with existing options (or better yet, vanilla site functionality).

• If you want dark mode, use dark reader. You also get dark mode on other websites.

• If you want simple analytics about your profile, use CF Analytics.

• If you want estimated rating changes, use carrot.

• For anything else, it's probably already possible in the vanilla site.

Hello Coders and Forcers!

A few days ago my friend FTS_Problem_C made a Blog asking for advice for reaching CM. It gained some attention and in the comments, a challenge was created by coderdhanraj:

Naturally, as someone who just became an expert and still has 200 points to go, I accepted the challenge. And so did 17 others. I am making this blog for 2 reasons:

1. To let more people in on the challenge

2. To set some sort of punishment for failing (something like what FTS_Problem_C mentioned in his blog) or reward for succeeding (although reaching CM is a reward in of itself :p).

If you have any ideas, or if you would like to join the challenge, please leave a comment below :)

I recently started the Segment tree course on the EDU, I found it very helpful. However, I noticed a small issue: The theory section gives away the solution too quickly. As given by this example:

The full solution was described immediately, leaving the reader little room to think about it for themself. I think this would be a better way to do it:

If you have any thoughts about this please put them in the comments :)
