Most prominent ORMs for GO are GORM, Ent, Bun and sqlc. Here is a little comparison of them with examples of CRUD operations in pure GO.

Here are my notes with step-by-step tutorial on how to implement and deploy to AWS a Telegram bot. I’ve added a quick start (long polling) and a production-ready path (webhooks), with examples in Python and Node.js.

Here we have a description of The Model Context Protocol (MCP), short notes on how to implement an MCP server in Go, including message structure, protocol specifications.

Apache Airflow is an open-source platform designed to programmatically author, schedule, and monitor workflows, - entirely in Python code, offering a flexible and powerful alternative to traditional, manual, or UI-based workflow tools.

Python uv (pronounced “you-vee”) is a modern, high-performance Python package and project manager written in Rust. It is designed as a drop-in replacement for traditional Python package management tools such as pip, pip-tools, virtualenv, pipx, and pyenv, aiming to simplify and accelerate Python development workflows

Since standard Ollama doesn’t have a direct rerank API, you’ll need to implement reranking using Qwen3 Reranker in GO by generating embeddings for query-document pairs and scoring them.

This little Reranking Go code example is calling Ollama to generate embeddings for the query and for eache candidate document, then sorting descending by cosine similarity.

Several examples of Dockerfiles for building and hosting Flutter web apps, Ubuntu-based Flutter Build image + Webapp image on Nginx.

Generating PDF documents programmatically can be an important feature in your application. Here we explore and give short review with examples of the libraries available in the Go programming language (Golang) for generating PDF files.

• For a direct Beautiful Soup analogue in Go, use soup.
• For CSS selector support, consider goquery.
• For XPath queries, use htmlquery.
• For another Beautiful Soup-inspired option, look at Node.

If you’re looking for a Beautiful Soup equivalent in Go, several libraries offer similar HTML parsing and scraping functionality:

In my new Go project that was using GORM I started getting error: pq: got 2 parameters but the statement requires 1

Go’s ecosystem offers a range of ORM (Object-Relational Mapping) tools and database libraries, each with its own philosophy. Here is a comprehensive comparison of four major solutions for using PostgreSQL in Go: GORM, sqlc, Ent, and Bun.

Here I list steps needed to implement pair of lambda functions in AWS SAM:

1. REST API Lambda: send message to SQS
2. SQS Lambda Trigger: process message from SQS

These are the step-by-step instructions on how to add layers to AWS Lambdas - in Python. Will be using base code generated by standard HelloWorld template example.

Reranking is a second step in Retrieval Augmented Generation (RAG) systems, right between Retrieving and Generating.
