#open-source + #code

A library that provides an embeddable, persistent key-value store for fast storage.

This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.

In the spirit of openness, we are publishing our internal documentation for how we do open source at Google. We invite you to take a look behind the scenes at how we use, release, and support open source projects and communities.

FlyDrive is a file storage library for Node.js. It provides a unified API to interact with the local file system and cloud storage solutions like S3, R2, and GCS.

Drive can be an excellent fit for applications that use cloud storage services to manage user-uploaded files. With Drive:

• You get a unified API for various storage services, including S3, R2, Digital Ocean spaces, GCS, and your local file system.
• Extensible API to add custom storage drivers.
• Unified exception handling.
• Baked-in security primitives to prevent common attacks like Path travesal.

ArduPilot provides a comprehensive suite of tools suitable for almost any vehicle and application. As an open source project, it is constantly evolving based on rapid feedback from a large community of users. The Development Team works with the community and commercial partners to add functionality to ArduPilot that benefits everyone. Although ArduPilot does not manufacture any hardware, ArduPilot firmware works on a wide variety of different hardware to control unmanned vehicles of all types. Coupled with ground control software, unmanned vehicles running ArduPilot can have advanced functionality including real-time communication with operators.

Installed in over 1,000,000 vehicles world-wide, and with advanced data-logging, analysis and simulation tools, ArduPilot is a deeply tested and trusted autopilot system.

The software suite is installed in vehicles from many manufacturers

Forgejo is a self-hosted lightweight software forge. Easy to install and low maintenance, it just does the job.

Today we’re releasing OpenAI Privacy Filter, an open-weight model for detecting and redacting personally identifiable information (PII) in text.

It is designed for high-throughput privacy workflows, and is able to perform context-aware detection of PII in unstructured text. It can run locally, which means that PII can be masked or redacted without leaving your machine. It processes long inputs efficiently, making redaction decisions in a quick, single pass.

Career-Ops turns any AI coding CLI into a full job search command center. Instead of manually tracking applications in a spreadsheet, you get an AI-powered pipeline that:

Evaluates offers with a structured A-F scoring system (10 weighted dimensions)
Generates tailored PDFs -- ATS-optimized CVs customized per job description
Scans portals automatically (Greenhouse, Ashby, Lever, company pages)
Processes in batch -- evaluate 10+ offers in parallel with sub-agents
Tracks everything in a single source of truth with integrity checks

Important: This is NOT a spray-and-pray tool. Career-ops is a filter -- it helps you find the few offers worth your time out of hundreds. The system strongly recommends against applying to anything scoring below 4.0/5. Your time is valuable, and so is the recruiter's. Always review before submitting.

Career-ops is agentic: Claude Code navigates career pages with Playwright, evaluates fit by reasoning about your CV vs the job description (not keyword matching), and adapts your resume per listing.

Heads up: the first evaluations won't be great. The system doesn't know you yet. Feed it context -- your CV, your career story, your proof points, your preferences, what you're good at, what you want to avoid. The more you nurture it, the better it gets. Think of it as onboarding a new recruiter: the first week they need to learn about you, then they become invaluable.

Built by someone who used it to evaluate 740+ job offers, generate 100+ tailored CVs, and land a Head of Applied AI role. Read the full case study.
