What is DriveLite architecture

## Introduction

DriveLite is an open-source, self-hostable file storage system designed with privacy-first principles. Unlike traditional cloud storage, DriveLite ensures your files are encrypted end-to-end by default, so even your server cannot see your data.

At the same time, DriveLite is flexible advanced users can opt into server-trusted mode to enable features like previews, AI tagging, and semantic search.

This post explains DriveLite’s architecture and how it balances maximum privacy with optional convenience.

---
## 1. Core Principles

- Privacy by default → End-to-end encryption (E2EE) + zero-trust.
- Flexible control → Users can choose server-trusted mode for enhanced features.
- Modular architecture → Storage, backend, and AI/search services are separate and scalable.

---
## 2. How DriveLite Handles Security

### E2EE + Zero Trust (Default)

- Files are encrypted in the browser before upload.
- Server only stores ciphertext, cannot read user files.
- Protects against server compromises, rogue admins, or cloud breaches.
- Ideal for privacy-conscious users and sensitive data.
- Use on device AI models

### Server-Trusted Mode (Optional)

- Admins can opt-in for server-trusted mode per deployment
- Enables advanced features:
- File previews
- Semantic search
- AI tagging and AI-assisted file organization

---
## 3. Components Breakdown
### Frontend Web (React + Tailwind)

- Handles encryption/decryption for E2EE by default.
- Offers clear privacy vs. convenience toggle for users or admins.
- On-device ML (in case of E2EE + Zero trust)

### Backend (Go + Echo)

- Serves APIs for file upload, metadata, sharing, and search.
- Detects if server-trusted mode is enabled and handles decrypted files accordingly.

### Storage (MinIo (S3-compatible ) / File system)

- Stores encrypted blobs in default mode.
- Can store decrypted content when server-trusted mode is active.

### Database Layer (SQLite / PostgreSQL)

- Stores metadata and encryption keys securely.
- Supports pluggable backends for scalability.

### AI + Semantic Search (Python + Qdrant + gRPC)

- Only has access to file content in server-trusted mode.
- Enables semantic search, tagging, and AI features when opted-in.

---
## 4. Why This Architecture?
- Privacy-first by default → E2EE ensures maximum data security.
- Feature-flexible → Users can opt-in for richer functionality.
- Modular & Scalable → Each component can be independently maintained, scaled, or replaced.
- Clear tradeoff → Users control their own security vs. convenience balance.

---
## 5. Roadmap & Vision

- Mobile clients (Flutter)
- Collaborative features with optional server-trusted mode
- AI-assisted file management
- Community plugins and extensions

---
## Conclusion

DriveLite’s architecture is privacy-first, flexible, and future-proof. By default, your data is encrypted and zero-trust, but if you want enhanced features like previews and AI search, you can opt-in to server-trusted mode.

This approach makes DriveLite stand out in the self-hosting ecosystem, offering both security-conscious users and feature-hungry users exactly what they need.

ZHCL — A Natural Language Compiler That Lets You Code in Your Own Words

## 🧠 ZHCL — 自然語言程式編譯器（Natural Language Compiler）

This is not a translator. This is not a prompt.
**This is a real compiler that takes traditional Chinese sentences as source code and generates valid, executable programs.**

---

### 🧩 What is ZHCL?

> A multi-target natural language compiler:
> You write code like this 👇

```zh
主函式 開始
輸出("你好世界")
結束

結束
Then it gets compiled to .c, .class, or .exe.

🚀 Key Features
Write programs in natural language (Traditional Chinese or English)

Output to C, JVM Bytecode (.class), or native executable

Works with math models, I/O, type resolution, _Generic

Self-contained CLI with --show-c, --emit-class, --strict flags

Built-in examples:

stonehenge.zh simulates Stonehenge solar alignment

kukulcan.zh simulates the serpent shadow of the Mayan pyramid

Fully open source (MIT)

📂 GitHub
👉https://github.com/Retryixagi/ZHCL
Contains:

Compiled binaries (CLI ready to use)

Examples written in .zh

Scientific simulations powered by natural language

🧪 Demo Example: Stonehenge
請輸入時間（年、月、日、時、分）
如果太陽仰角 ≈ 巨石陣對準角度，輸出「對準成功」


Yes, this is fully executable logic written in Chinese.

❤️ Why I made this?

Because programming should not be limited by syntax.
Because not everyone thinks in English.
Because language is the most powerful interface humans have — and compilers should honor that.

Let me know what you think.
If you want to help expand to other languages (like Japanese, French, etc.), feel free to PR or fork it.

🧠 I'm actively looking for collaborators, testers, and language contributors.

What is the best license for dual licensing (free + paid)?

I want to release my source code under a free license that requires attribution, but also offer a paid license where attribution is not required.

Which open source license should I choose as the base for this kind of dual licensing?

GPL v3 seem like a good fit for the free license. But I want your suggestions.

I just became a maintainer of a very popular project. What are the first things you think I should do?

Hello all,

My name is Nariman (verification: GitHub), and I just became one of the maintainers of a very popular project, http-server. If you're a JavaScript developer, you may already have used this module in your projects; if not, the goal of http-server is to give you a dead-simple static HTTP server, mostly used for local development.

I'm determined to improve this gem of the OSS community as best as I can. If you've been in a situation like this before, please let me know what some of the first things you would do. If you also have any feedback, feature requests, bugs, ... they are super welcome as well! Anything to help me make this project the best in the world :)

Traffic Monitor flagged as Trojan (WinNT/Winring0.G) – Safe to keep or uninstall?

I’m running into a security warning with Traffic Monitor

https://github.com/zhongyang219/TrafficMonitor

and I’m not sure how to handle it.

Windows Security Alert:

VulnerableDriver:WinNT/Winring0.G  
Alert level: Severe  
Status: Active  
Date: Sun 21-Sep-25 06:51 PM  
Category: Trojan  
Details: This program is dangerous and executes commands from an attacker.  

Affected item:  
C:\TrafficMonitor_V1.85_x64\TrafficMonitor\TrafficMonitor.sys

I also noticed the CPU temperature readings stopped working about 3 days ago, which seems to line up with an issue mentioned in the GitHub repo:
https://github.com/zhongyang219/TrafficMonitor/issues

Now I’m stuck-should I uninstall Traffic Monitor completely?

The tough part is I’ve relied on it for years to monitor:

Upload/Download speeds
Memory usage
Total network speed
CPU usage
GPU usage
CPU/GPU temperature

And I really need the taskbar window display it provides.

Is there a safe alternative that gives the same features?

HelixDB - An open-source graph-vector database built in Rust

Hey r/opensource wanted to show off a project a college friend and I have been working on for the past 9 months

https://github.com/helixdb/helix-db

Why hybrid?
Vector DBs are great for semantic search (e.g., embeddings), while graph DBs are needed for representing relationships (e.g., people → projects → organisations). Certain RAG systems need both, but combining two separate databases can be a nightmare and hard-to-maintain.

HelixDB treats vectors as first-class types within a property graph model. Think of vector nodes connected to other nodes like in any graph DB, which allows you to traverse from a person to their documents to a semantically similar report in one query.

Currently we are on par with Pinecone and Qdrant for vector search and between 2 and 3 orders of magnitude faster than Neo4j.
As Rust developers, we were tired of the type ambiguity in most query languages. So we also built HelixQL, a type-safe query language that compiles into Rust code and runs as native endpoints. Traversals are functional (like Gremlin), the language is imperative, and the syntax is modelled after Rust with influences from Cypher and SQL. It’s schema-based, so everything’s type-checked up front.

Would love your feedback – especially from anyone who's worked on databases :)

BTW, GitHub stars are always appreciated :) https://github.com/helixdb/helix-db

How do you get traction for an open source i18n project?

I built an open source internationalization (i18n) tool that I think solves i18n way better than what’s out there. It’s free, will always stay free, and I honestly believe most devs who try it will prefer it.

The “business” side isn’t aimed at devs at all, the plan is to monetize through a CMS for marketers/designers/content people. Basically, devs never pay, and the whole point is to get translation work off our plate so we can focus on shipping features.

The problem: nobody really knows about it yet. I’m not looking to spam, but I’d like to get it in front of more developers so they can try it out and (hopefully) spread the word if they like it. So for anyone who’s grown an open source project before:

How did you get your first wave of users? Any good places to share this kind of project where people actually care? Any tips on making sure devs understand the monetization isn’t aimed at them? Curious to hear what worked (or didn’t work) for you.

I built my own color-scheme for VS Code

I’ve been messing around with color palettes for a while, and I finally put together something I’m proud of: Eclipse Dawn (softer dark) and Eclipse Midnight (deeper dark).

The idea was to take some inspiration from Eclipse’s vibe but modernize it — better contrast, softer on the eyes, and consistent syntax highlighting that feels balanced for long "starring" sessions.

If anyone wants to give it a shot it's **here**, and as the time goes I'm adding more themes to the stuff I use.

Looking for testers: Self-Hosted File Converter, OCR, Transcriber, TTS

Hey, I've been spending the last few days building a self-hosted file converter with some added support for ocr, tts, and stt. This is not revolutionary, since it just wraps many tools into a webui but I couldn't find any alternatives (ConvertX is nice but fails a lot and has clunky ui).
It comes with OIDC support and pre-built Docker images!

Please check it out, it's still early development and I need people testing functionality since there are A LOT of formats to potentially test out.

How to responsibly hand over maintainership of my open-source project?

Hi everyone,

I’m the maintainer of QRCoder, a .NET library for generating QR codes. After several years, I’ve reached a point where I can no longer properly maintain the project:

I haven’t developed in C# for years, so I’ve lost touch with the ecosystem. (In my main job I switched to Python in 2021)
I’ve become frustrated with the increasingly harsh tone and high expectations from some users.

Because of this, I’d like to step down and hand the project over to someone who has the motivation and technical expertise to continue it. However, I’m unsure how to best approach the transition. Some options I’ve thought about:

1. Adding a new maintainer to my repo – but would someone really want to maintain it if I’m still technically the “owner”?
2. Transferring the repo to a new owner – but I worry about trust: someone could misuse it (e.g., distributing malicious code or rewriting history to claim the work as theirs).
3. Letting someone fork it – and then I’d archive my repo and link to the fork.

I also don’t know the best way to find a trustworthy new maintainer. Would simply putting a note in the README and issues be enough? Should I try to "vet" the new maintainer somehow?

Has anyone here gone through this before? How did you responsibly hand over your project without it being abused?

Any advice or experiences would be greatly appreciated!

Join the Parkinson Helper Phone App Project!

Hi Devs,

I’m not a Swift expert—my background is mainly in Python—and I’ve leaned heavily on CLI AI tools to develop Parkinson Helper into a functional MVP for Parkinson’s patients. I rely on a spec driven approach, with a progressive build, test, and next step methodology. I do apologize if the code or structure doesn’t yet meet typical mobile app standards; this was a "figure it out" effort driven by necessity.

Did searched the App Store for a tool to support Parkinson’s patients but found none that fully addressed their needs for complex tasks like dynamic medication scheduling, task management, and blood pressure monitoring. Thus, the decision to built Parkinson Helper..

This open-source iOS (Swift/SwiftUI) MVP currently offers: dynamic medication schedules, daily task checklists, adaptive UI, blood pressure tracking with graphs, historical data, text-to-speech, and on-device privacy via Core Data. It’s localized in English, Mandarin, Malay, and Tamil, with plans to support more languages.

We need your help to scale this community-driven project! Priorities include:

1. **Critical** | Upgrading the Medication Profile system to Core Data for multiple profiles, with a workflow to securely download profiles in CSV format to the device.
2. Expanding support to Android and other OS ecosystems.
3. Adding more language localizations.
4. Integrating onboard AI for data summaries (e.g., task completion rates, BP trends).
5. Implementing computer vision to auto-capture blood pressure readings (replacing manual input).

Join us on GitHub: https://github.com/parkinsonhelper/parkinson-helper/blob/main/README.md
Check out our intro video: https://www.youtube.com/watch?v=ES8kmNoG8FQ.
Let’s empower Parkinson’s patients worldwide together!
