I am here to tell you that dreams come true

[Luke Barousse @LukeBarousse]

Data Nerds! It's only taken me over 2 years, but I finally launched my FREE Data Analyst Bootcamp!

This 35-hour video is what I wish I'd had when I got started; it's for those with no degree or experience, helping one go from zero to job-ready.

For this bootcamp, we’re focusing on the top 4 demanded skills for a Data Analyst
1️⃣ SQL (45% of job postings)
2️⃣ Excel (32%)
3️⃣ Python (31%)
4️⃣ Power BI (28%)

But here's what makes this more than just a "How-To" video. It's not about the tools. The real work is learning how to be a data analyst and actually perform the analytics. The tools? They're just a necessity to facilitate it.

And the best way to learn all that? You build it:
🛠 6 hands-on portfolio projects (because employers want experience)
🤖 AI built into your workflow to learn and work efficiently
🐙 GitHub to share everything you build

So you finish each skill with something real to show, not just a "completed" badge.

Now the real talk. I pulled the numbers from my own course-takers on how long each skill will take to learn:
🐘 SQL ~3 months
❎ Excel ~3 months
📊 Power BI ~2 months
🐍 Python ~6 months

Realistically, that's 8 to 12 months to transition if you're doing this part-time.

Alright, let's get to building. 🤙

[Alex Freberg @Alex_TheAnalyst]

In this weeks PostgreSQL lesson we are starting with the basics of Select and From.

These are the building blocks of writing SQL and are used in almost every query you will write.

(Ignore my face) because I'm releasing a new 2026 FREE Data Analyst Bootcamp on YouTube next Week!!

I created the first ever Data Analyst Bootcamp about 3 years ago and millions of people have taken it. Since then, I've created a lot more content and I wanted to update it.

Here's what it already included:
1. MySQL
2. Excel
3. Tableau
4. Power BI
5. Python
6. Pandas
7. Building a Portfolio Website
8. Creating a Resume
9. Practicing for Technical Interviews
10. Azure
11. AWS
12. How to use LinkedIn to Land a Job

New Content Being Added:
13. R for Data Analysis Series
14. Git and GitHub Series
15. Data Fundamentals Series
16. Databricks for Beginners Series
17. ETL in Databricks Series

This will be the longest free Data Analyst Bootcamp in the world (clocking in at around 29 hours). It took 3 hours just to download it!

I'm super excited and hope it'll continue to be extremely helpful to everyone out there trying to learn data skills!

Another YouTube channel I recently discovered that explains Excel in a very beginner-friendly way is this one 👇

Great for anyone trying to learn Excel from scratch.

I find the first 3 chapters relevant for Beginners in Data. It expands your view of how you should see data at first glance.

[Alex Freberg @Alex_TheAnalyst]

Today we are finishing out our Databricks series with the best one yet.

In this video you can learn how to build data pipelines in Databricks in under 1 hour!

We start with Data Ingestion, then look at building ETL Pipelines, Orchestrating and Automating everything - and then at the end we have a full Project.

[Apache Spark @ApacheSpark]

New video with Jerry Peng on Apache Spark Structured Streaming!⚡️

In this video, we walk through how the engine actually works under the hood: the unbounded table abstraction, micro-batch execution, exactly-once semantics via the write-ahead log, and the design decisions that still get misunderstood nearly a decade in.

🎥 Dive in: https://t.co/CoBw3KtjNR

This is part 1 of a two-part series. If you want to understand why Structured Streaming is the default streaming engine for data platforms at scale, and why micro-batch is a design choice, not a compromise, start here.📍
