How to Install Apache Airflow on Ubuntu 24.04 with Nginx and HTTPS

·1 views

Apache Airflow is an open-source workflow management platform that uses Python-based Directed Acyclic Graphs to schedule and automate data pipeline tasks such as ETL processes. A step-by-step guide outlines how to install Airflow on Ubuntu 24.04 using pip inside a Python virtual environment. The setup requires configuring PostgreSQL as the metadata database and updating Airflow's core settings to enable parallel task execution. The deployment is further secured by placing the instance behind an Nginx reverse proxy with a Let's Encrypt SSL certificate. Once complete, users have a fully functional Airflow instance accessible over HTTPS and testable with a sample DAG.

Why navigator.clipboard.writeText() Silently Fails When Users Switch Tabs

A subtle browser behavior can cause clipboard copy functions to fail without any visible error when users switch tabs or windows mid-operation. The Async Clipboard API requires the document to have active focus at the exact moment writeText() is called, not merely when the user first clicked. If an awaited operation — such as a fetch request — creates a timing gap between the click and the clipboard call, focus may have shifted, causing the browser to silently reject the promise with a NotAllowedError. Common fixes like loading spinners, try/catch blocks, or retries do not resolve the issue because they fail to address the root cause of lost document focus. The recommended solution is to pass a promise directly into ClipboardItem so the clipboard slot is claimed during the original click gesture, while the data resolves asynchronously afterward.

GPT4All Lets You Run AI Language Models Locally Without Internet Access

GPT4All is a free, open-source desktop application that allows users to run large language models locally on Windows, macOS, and Linux without an internet connection. It supports GGUF-format models from sources like Hugging Face and can also connect to API-based providers such as OpenAI, Groq, and Mistral. The application can be installed on Ubuntu and Debian-based systems via an installation binary or Flatpak, while Windows and macOS users have dedicated installers available. GPT4All also supports retrieval-augmented generation (RAG), enabling users to chat with their own local documents. Additionally, it includes a built-in API server that can be secured and made remotely accessible via HTTPS behind a reverse proxy.

NVIDIA Dynamo and vLLM Enable Scalable LLM Inference Across Multi-GPU Setups

NVIDIA Dynamo is an open-source inference framework designed to deploy large-scale generative AI models across multi-node, multi-GPU environments with high throughput and low latency. It supports both aggregated serving for single-GPU configurations and disaggregated serving, which separates prompt processing and response generation across different GPUs for independent optimization. The framework integrates with backends such as vLLM, SGLang, and NVIDIA TensorRT-LLM, using etcd for service discovery and NATS for inter-component message passing. A deployment guide covers infrastructure setup, container configuration via Docker Compose, and two serving patterns using vLLM as the inference backend. The setup requires a minimum of one GPU for aggregated serving and four GPUs for disaggregated serving, along with the NVIDIA Container Toolkit and Docker Engine.

How to Deploy FastAPI with Gunicorn and Nginx on Ubuntu 24.04

A technical guide outlines the steps to deploy a FastAPI application on Ubuntu 24.04 using Gunicorn as the application server and Nginx as a reverse proxy. FastAPI, a modern Python web framework, supports asynchronous programming and ships with built-in interactive API documentation via Swagger UI. The setup uses Gunicorn with a Uvicorn worker class to handle ASGI support, while a systemd unit file manages the Gunicorn process as a persistent background service. Nginx sits in front of the application to handle incoming web traffic and route requests through a Unix socket. The deployment is completed by securing the application with a free SSL certificate, making it accessible over HTTPS on a custom domain.
