How to Self-Host Postiz Social Media Scheduler on Windows Using Docker

·1 views

Postiz is an open-source social media scheduling tool with over 33,000 GitHub stars, offering a self-hosted alternative to platforms like Buffer or Hootsuite. A community guide details how to install it on Windows 10 or 11 using Docker Desktop, Git Bash, around 15 GB of free disk space, and at least 8 GB of RAM. The setup involves cloning the official Docker Compose configuration, generating a unique JWT secret, and configuring a few environment variables before launching the stack. A key limitation of local installation is that scheduled posts will only be published while the machine is running and Docker is active — if the PC is asleep or shut down, posts are delayed until the stack restarts. For reliable scheduled posting, the guide recommends hosting Postiz on a VPS or using the paid hosted version instead.

Kimi K3 Sets Open-Weight Record as OpenAI and Anthropic Battle for Coding Dominance

Moonshot AI released Kimi K3 this week, a 2.8 trillion-parameter multimodal model with a 1 million token context window, with open weights expected by July 27; it is already live on their API and reportedly outperforms several top closed models in coding benchmarks. Separately, Thinking Machines Lab, founded by former OpenAI executive Mira Murati, launched Inkling, a 975 billion-parameter open-weights foundation model trained on 45 trillion tokens across text, images, and audio. OpenAI consolidated its Codex tool into ChatGPT under the rebranded product ChatGPT Work, which saw 2.5x usage growth in a week, though the move drew backlash from power users whose established workflows were disrupted. Anthropic responded swiftly by resetting usage allowances for all Claude users, signaling an intensifying competition to become the default coding agent for developer teams. Industry observers note that the broader race is shifting from raw model capability toward the infrastructure and tooling ecosystems built around AI models.

Developer Builds YourOnlyAI to Match Users With the Right AI Tool for Any Task

A developer has launched YourOnlyAI, a platform designed to help users identify the most suitable AI model for a specific task without manually searching through blogs or testing multiple tools. The tool works by asking users to describe their goal and then providing practical, task-specific AI recommendations. The creator says the focus is on actionable guidance rather than simply maintaining a directory of AI tools. Improved task categorization is among the features currently in development. The developer is actively seeking community feedback on usability, recommendation criteria, and trust factors.

How to Use HC-SR04 Ultrasonic Sensor with Arduino for Distance Measurement

The HC-SR04 is a popular ultrasonic sensor in the Arduino ecosystem that measures distances ranging from 3 cm to 300 cm using 40 kHz sound waves. It works by emitting ultrasonic pulses from a trigger pin, waiting for the echo to bounce back from an object, and calculating distance based on the sound's travel time. The sensor connects to an Arduino UNO via just four pins — VCC, GND, Trig, and Echo — making it accessible for beginners. With an accuracy of approximately ±3 mm and reliable performance across lighting conditions, it is widely used in robotics, smart parking, obstacle avoidance, and home automation projects. The distance is calculated using the formula: Distance (cm) = Echo Time (µs) ÷ 58.3, derived from the speed of sound.

Open-Source Tool Uses Claude AI to Build Smarter Job Search Workflows

An open-source project is gaining attention for turning Anthropic's Claude into a structured, AI-powered career assistant for job seekers. The tool is designed to match candidate profiles with relevant opportunities, optimize resumes, and improve the consistency of job applications. Rather than encouraging users to send mass applications, the system focuses on building a repeatable, quality-driven job search process. The project is aimed at developers, job seekers, and AI enthusiasts looking to modernize how they approach hiring. Details about the tool were shared via a developer blog post published in late April 2025.
