I’m a third-year CS student and over the past year I’ve been building minidbms — a database engine written from scratch in C and Python — to study buffer pool replacement policies experimentally.…
Messing around with steganography because I find it really interesting. (And maybe scarey?) I scraped a bunch of real HN comments (most of what is usually gibberish to me) and created an engine that encodes messages into the real looking comments.…
Hey r/compsci, I’ve been learning systems programming and database internals, so I started building Ark — a SQL-like relational database engine written entirely from scratch in C++.…
Anyone get desk rejected email today? I got and it said Desk Reject Comments: This submission violates the formatting rules and has been desk rejected. I thought it was because my paper title was not strong enough to be a position paper.…
It is easy to use, publishable via GitHub actions, works with all 3 major browsers, has HMR for background script and content scripts too. It uses an internal messaging module and Zod for type-safe API queries.…
Hey everyone, I’ve been experimenting with token optimization for LLM agent frameworks by treating terminal and tool outputs as a data compression problem rather than a text-filtering one.…
I’m here to challenge the status quo once again: The control overhead of permutation generation can be reduced from O(n!) to O((n-1)!). I know the total number of permutations is $n!$, but here is the real question: Why on earth should your control flow…
Quantum computing still stumbles on fragility, where tiny disturbances can wreck calculations. ETH Zurich researchers built a geometric swap gate with neutral atoms that stayed remarkably stable across 17,000 qubit pairs, hinting at a sturdier path toward…
Hi everyone! I'm an undergrad who just started my first Natural Language Processing course this semester and really enjoy it! In one of the early lectures, we were talking about the Levenshtein distance and other algorithms, and I was astonished to learn…
Hey r/compsci, I'm a CS professor and built this tool for teaching bootloader development without making students install anything. **What it does:** - Write x86 NASM assembly in the browser (CodeMirror editor with NASM syntax + autocomplete) - Assemble…
Applying for jobs is tedious enough, but having to manually adjust spacing and formatting in Word every time I tweak a cover letter is driving me crazy. I want to move my workflow over to LaTeX so it's cleaner and easier to version control.…
I'm working on an open source codebase intelligence tool. One layer of it scores every file 1-10 using 15 deterministic biomarkers. No LLM. AST parsing via tree-sitter plus git history. Wanted to know if the scores actually mean anything.…
