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.

Generating PDF Reports Using Python

Python, with its extensive libraries and modules, offers powerful tools for generating professional PDF reports.

• 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

I aggregated some VS Code extentions installation statistics by different programming languages. And the most popular is Python. Then C++.

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.

Use PyInstaller to package Python programs as standalone executables. It works on Linux, Windows, and Mac.

Not the most efficient way, but usable.

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.

A quickstart - how to Create Flutter fullstack project on AWS Amplify platform.

We can write lambda function for deployment to AWS in several languages. Let’s compare the performance of (almost empty) functions written in JavaScript, Python and Golang…
