Hey Hacker News The ones that know me here know that I am a productivity geek.

After DockFlow to manage my Dock and ExtraDock, which gives me more space to manage my apps and files, I decided to tackle the macOS big boss: the menu bar.

I spend ~40% of my day context-switching between apps — Zoom meetings, Slack channels, Code projects, and Figma designs. My macOS menu bar has too many useless icons I almost never use.

So I thought to myself, how can I use this area to improve my workflows?

Most solutions (Bartender, Ice) require screen recording permissions, and did not really solve my issues. I wanted custom menus in the apps, not the ones that the developers decided for me.

After a few iterations and exploring different solutions, ExtraBar was created. Instead of just hiding icons, what if the menu bar became a keyboard-controlled command center that has the actions I need? No permissions. No telemetry. Just local actions.

This is ExtraBar: Set up the menu with the apps and actions YOU need, and use a hotkey to bring it up with full keyboard navigation built in.

What you can do: - Jump into your next Zoom call with a keystroke - Open specific Slack channels instantly (no menu clicking) - Launch VS Code projects directly - Trigger Apple Shortcuts workflows - Integrate with Raycast for advanced automation - Custom deep links to Figma, Spotify, or any URL

Real-world example: I've removed my menu bar icons. Everything is keyboard- controlled: cmd+B → 2 (Zoom) → 4 (my personal meeting) → I'm in.

Why it's different: Bartender and Ice hide icons. ExtraBar uses your menu bar to do things. Bartender requires screen recording permissions. Ice requires accessibility permissions. ExtraBar works offline with zero permissions - (Enhance functionality with only accessibility permissions, not a must)

Technical: - Written in SwiftUI; native on Apple Silicon and Intel - Zero OS permissions required (optional accessibility for enhanced keyboard nav) - All data stored locally (no cloud, no telemetry) - Very Customizable with custom configuration built in for popular apps + fully customizable configuration actions. - Import/export action configurations

The app is improving weekly based on community feedback. We're also building configuration sharing so users can share setups.

Already got some great feedback from Reddit and Producthunt, and I can't wait to get yours!

Hi HN,

I’m releasing minikv, a distributed key-value and object store in Rust.

What is minikv? minikv is an open-source, distributed storage engine built for learning, experimentation, and self-hosted setups. It combines a strongly-consistent key-value database (Raft), S3-compatible object storage, and basic multi-tenancy. I started minikv as a learning project about distributed systems, and it grew into something production-ready and fun to extend.

Features/highlights:

- Raft consensus with automatic failover and sharding - S3-compatible HTTP API (plus REST/gRPC APIs) - Pluggable storage backends: in-memory, RocksDB, Sled - Multi-tenant: per-tenant namespaces, role-based access, quotas, and audit - Metrics (Prometheus), TLS, JWT-based API keys - Easy to deploy (single binary, works with Docker/Kubernetes)

Quick demo (single node):

git clone https://github.com/whispem/minikv.git cd minikv cargo run --release -- --config config.example.toml curl localhost:8080/health/ready # S3 upload + read curl -X PUT localhost:8080/s3/mybucket/hello -d "hi HN" curl localhost:8080/s3/mybucket/hello

Docs, cluster setup, and architecture details are in the repo. I’d love to hear feedback, questions, ideas, or your stories running distributed infra in Rust!
