awesome-competitive-programming VS magic-trace

There are a bunch of good free resources here but they’re are a lot less digestible https://github.com/lnishan/awesome-competitive-programming

I suggest you look at this very comprehensive and awesome list: https://codeforces.com/blog/entry/23054

Awesome Competitive Programming

First, make a codeforces account and then refer to this resource list as you continue to solve problems.

Start your competitive coding journey from Algorithms, Competitive Coding to Data Structure resources, everything in one awesome repository. Check it OUT!

You need more than logic and practice. These contests are not just intelligence tests. They also test knowledge of certain algorithms, techniques, and mathematical skills. My suggestion would be to pick a problem from that contest and spend some time trying to solve it (no more than an hour or two even for harder problems). Then whether or not you solve it yourself, read an editorial or someone else's solution. Make a note of any concepts you're not familiar with, and read up on them. You should be able to find everything you need online, but https://github.com/lnishan/awesome-competitive-programming has other sources including books. Then solve the problem again and make sure you understand it. Once you do this enough times, you'll cover all the topics that are likely to come up in that contest.

Take a look at the Awesome Competitive Programming list on GitHub. All the standard references are there.

I really like magic-trace [0].

Not that the exact tracing relies on Intel PT - support for AMD was added recently but uses perf so suffers from the same sampling/skew issues, but is still very useful.

Would love to see this integrate with magic trace [1]. I'll need to look at the code for the flamegraph plugin, because handling nanosecond timestamps in flamegraphs seems to break most tools due to float precision.

As for inner workings, have you looked into magic trace? I want to play around with it but last I checked, it doesn't work on macs.

I really hope he can work with cloud vendors and Intel to make Processor Trace a more popular and easier to use capability.

It's unfortunate how https://github.com/janestreet/magic-trace and PMUs in general can't be used by lots of people using cloud VMs.
