Developer builds self-hosted Telegram AI assistant with persistent local memory

·1 views

A developer has built Avelina, a self-hosted personal AI assistant on Telegram that retains long-term memory across sessions using a local SQLite database and on-device embeddings. Unlike cloud chatbots that reset after each session, Avelina stores user facts, learned corrections, a conversation journal, and emotional state across multiple database tables. Each incoming message is converted into a vector using a local embedding model, and a cosine-similarity search retrieves the most relevant memories to include in the system prompt before every response. Because all processing happens on a private Linux VPS with no third-party services, user data never leaves the server. The full stack is available as a one-command install at avelina.ai.

Developer Launches Hilo: A Word Game Built Around Binary Search Logic

A developer has released Hilo, a browser-based word game that applies the concept of binary search to gameplay. The game challenges players to guess a target word by narrowing down possibilities using higher/lower style feedback, mimicking how binary search algorithms work. It was shared on Hacker News as a personal project under the 'Show HN' category. The game is accessible at hilogame.cc and appears to be an independent, hobby-driven creation. The post attracted minimal early engagement, with just a few points and no comments at the time of publication.

SlaveCode Code Execution Platform Earns Spot in Official Judge0 README Showcase

SlaveCode, an online platform that compiles and executes user-submitted code in real time, has been added to the official README showcase of Judge0, a widely used open-source code execution engine. Judge0's creator, Herman Zvonimir Došilović, discovered the project and opened a GitHub issue to express his appreciation before adding it to the showcase. SlaveCode uses Judge0 as its core execution engine, running it on isolated Microsoft Azure VMs that are physically separated from the platform's main API and databases hosted on Google Cloud Platform. This architectural separation is designed to contain any potential security breach within the execution sandbox, keeping user data and core infrastructure secure. The developer credited detailed public documentation of SlaveCode's architecture on Dev.to as the likely reason the project came to Došilović's attention.

OMR Python Library Replaces Repetitive Data Audit Boilerplate with One Command

A developer has released OMR (Omni Data Refinement), an open-source Python library designed to streamline dataset quality checks that typically require dozens of lines of boilerplate code. The library generates a 0–100 health score across five dimensions — completeness, uniqueness, consistency, validity, and conformity — with a single function call. OMR also supports auto-cleaning with a transformation log, schema validation, statistical analysis, and drift detection using methods like PSI and KS Test. It requires only pandas, numpy, and rich, with no cloud dependencies or large language models involved. The library is available via pip and its source code is publicly hosted on GitHub.

Five Common Regex Mistakes and How to Catch Them Before Production

Regex patterns often contain subtle flaws that only surface with specific inputs, making debugging a common challenge for developers. Greedy quantifiers, misplaced anchors, and misconfigured flags are among the most frequent causes of unexpected matching behavior. Capture group interference and overly simplistic patterns that fail on real-world edge cases — such as complex email addresses — also trip up many implementations. Syntax errors like unbalanced brackets or invalid lookbehind expressions can cause unhandled runtime exceptions if not caught during development. Using a visual regex tester that highlights matches in real time and displays individual capture group values can significantly speed up the debugging process.
