DuckDB is an in-process SQL OLAP database management system.

New announcement 2023-05-23 about the single place of MS; it’s like a Databricks replica, except for the tools in Azure without needing to go into Azure (see more below).

Retrieval-augmented generation is a technique that can provide more accurate results to queries than a generative large language model on its own because RAG uses knowledge external to data already contained in the Large Language Models (LLMs). vector dat…

A curated list of many open-source data engineering projects collected over the years.

Consolidation in the Data Engineering market is happening quickly.

Everyone is using Obsidian for AI, or wants to use it to become more productive.

With data engineering and 15 years of building Data Orchestration tools like Airflow, Dagster, Prefect, and Kestra, we are now doing the same for AI agents.

I’m saying this repeatedly: have your own website and domain.

The cycle of hype terms is going strong: chatting, plan mode, tokenmaxxing, loop engineering, harnesses, graphs, orbs, and terms will continue ^8063d8 Others that nobody talks about anymore are: Moltbot/OpenClaw ^ee800e In similar terms, we also, or still…

Instead of Orchestration for data engineering jobs, AI orchestration is all about scheduling and orchestrationg AI Agents.

In times of AI Writing, writing manually is more important than ever.

HackMD is Google Docs for Markdown.

Consolidation in the Data Engineering market is happening quickly.

The difference between writing within the app you publish, let’s say, Twitter, LinkedIn, or the newsletter in Substack, Medium, Email, etc., and writing it in Obsidian or a note app can make a big difference, but for different reasons.

Another one that goes hand in hand with Stoic is Journaling.

Writing is therapy!

Why is this important?

When checking how much I have written over the years, it amazes me every time, and most of the inspirations, ideas, and brainstorm came initially from my Second Brain.

The HEY screener is probably one of the biggest life improvements introduced in the last two years (for productivity) that I can’t live without anymore.

To create my favorite feature from HEY.com, the E-Mail Screener, I had to get the existing work and screen in and out of the list for two years or so.

Note-taking is like saving money with interest.

I like to collect notes over time on my Second Brain, and eventually, when I figure something substantial to share, something I learned, I write a blog post about it.

Learning to Think Again, and the Cost of AI Dependency.

Kestra is a universal open-source orchestrator that makes both scheduled and event-driven workflows easy.

AI Writing differs from coding because it’s consumed by different stakeholders.

I like Naval’s take, as elaborated above, which says it all depends on who the customer is.

I’m saying this repeatedly: have your own website and domain.

In times of AI Writing, writing manually is more important than ever.

Everyone is using Obsidian for AI, or wants to use it to become more productive.

To me, AI writing always results in this: They always look nice at first sight, but over time, they look all the same: complex, unnatural, and busy.

Whether you work in a different field or are curious about what Data Engineering is, this is the right place to start as a data engineer.

To me, the fundamentals of data engineering are well described in Fundamentals of Data Engineering Book with the Data Engineering Lifecycle: Image from the above mentioned book | Source If you want to learn related fundamentals, look at Data Engineering T…

In today’s landscape, a data engineer is pivotal in overseeing the entire data engineering process.

This is a delicous Ramen soup, that you can make at home.

Apache Arrow is in-memory analytics format.

The Modern Data Stack (MDS) comprises a suite of open-source tools designed for end-to-end analytics.

DataFusion is an extensible query execution framework, written in Rust, that uses Apache Arrow as its in-memory format.

I like constraints to nourish artistic work, to unblock you when you have total freedom.

Yazi is a blazing-fast terminal file manager to replace GUI-first file managers.

Git like versioning on top of object storage/Data Lakes and databases. # What are the benefits?

Everyone who can write has a competitive advantage because not everyone can do it.

Tmux as the most know multiplexer of this category has now many copy-cater, that have more modern design and better default shortcuts, though that depends on the user.

I have a love for nice fonts. # Reading and Writing Fonts Atkinson Hyperlegible (mentioned Your favourite fonts choice and why?

Open source software refers to software projects shared online on GitHub, Codeberg, Tangled, or other GitHub Alternatives, usually with a git repository.
