Problem Links and Progress Logs
Binlogs opened with daily progress updates and links to LeetCode problems, moving through questions such as Maximum Width Ramp and Longest Nice Subarray. By January, the channel was also recording the satisfying moment of solving a previously unsolved problem independently.

Contest Analysis Mode
The channel announced that contest analysis would become part of its programming log, then explained solved problems with implementation, sets, sorting, binary search, and other techniques. Contest updates tracked results too: some posts report solving two or four problems during a contest, with additional problems finished afterward.

Short Finds, New Skills, and qusaqus
Later posts became a concise shelf of discoveries: branding and linguistics, AI, frontend tools, yosupo judge, and a 3D-graphics formula. In October 2026, the channel shared the Anatomy LLM Skill and then posted qusaqus, made with that skill.

The post that explains the channel's new contest-analysis format.
I regularly participate in Competitive Programming contests, so from now on I will be giving contest analysis for the questions I solved in those contests here.

A denser contest walkthrough spanning string ordering, gcd reduction, and inclusion-exclusion.
A. the question wants to order the string such that "FFT" or "NTT", don't appear as a substring in the string. approach: take 'F' and 'N' characters to the end...

In their own words.
I regularly participate in Competitive Programming contests, so from now on I will be giving contest analysis for the questions I solved in those contests here.
today I was able to solve it without any help.
