I made Keepr, a simple offline CLI password manager for developers who prefer keeping secrets local and working entirely in the terminal.

Everything is stored in an encrypted SQLCipher database, protected by a master password. A time-limited session keeps the vault unlocked while you work, so you don’t need to re-enter the password constantly. Keepr never touches the network.

It includes commands to add, view, search, update, and delete entries, plus a secure password generator and clipboard support.

Technical details:

- AES-256 via SQLCipher

- PBKDF2-HMAC-SHA256 (1.2M iterations) for deriving the KEK

- KEK decrypts a stored PEK, which encrypts the vault

- Session file holds the PEK until expiry

PyPI: https://pypi.org/project/Keepr/

I would love some feedback, criticism or any questions, especially on UX or security!

Thanks for looking!17:T44c,Hi everyone,

I’ve just finished writing a 1600-page data structures book that contains 130 fully original academic-style problems, each with complete solutions, proofs, amortized analysis, diagrams, and detailed explanations.

The book is designed for:

university-level advanced data structures learning

self-study for engineers

technical interview preparation (many problems are structured like interview challenges)

deep understanding of heaps, trees, union-find, RMQ, hashing, string structures, and more

I also included two new data structures that I designed myself — the Layered Summary Heap (LSH) and the Triple-L Heap — with step-by-step explanations and use cases.

I would appreciate feedb
