Hi everyone
Starting this week, I am launching a new Saturday edition of DataExec. It is shorter, lighter and designed to give you five quick, high value items in the data and AI space. Nothing heavy, just something interesting for your weekend.
Tweet of the Week
We all have someone in our team who changes data just to fit their narrative 😆
Tool to Try
🧰 Julius AI - turn spreadsheets or datasets into insights by asking plain-language questions (no code needed).
💡 Weekend assignment: Upload a dataset you have recently used (or exported) and ask Julius AI one question you have always wished you could answer quickly. Note how long it takes, and what new angle you discover.
The Gold standard for AI news
AI keeps coming up at work, but you still don't get it?
That's exactly why 1M+ professionals working at Google, Meta, and OpenAI read Superhuman AI daily.
Here's what you get:
Daily AI news that matters for your career - Filtered from 1000s of sources so you know what affects your industry.
Step-by-step tutorials you can use immediately - Real prompts and workflows that solve actual business problems.
New AI tools tested and reviewed - We try everything to deliver tools that drive real results.
All in just 3 minutes a day
One to Read
📘 Python Data Science Handbook by Jake VanderPlas (FREE) → Link here
This covers the practical workflows for data such as cleaning, visualizing, modelling. Even if you are not a developer, reading this gives you better fluency when you talk with analytics teams.
💡 Weekend tip: Jump into Chapter 2 (“Data Manipulation with Pandas”). Spend 10 minutes. Think: In my job, what dataset would be easier to work with if I used one new trick from this chapter?
One to Watch
🎬 How AI Changes Your Workforce - from MIT Sloan
You will see how companies are rethinking roles, workflows, and data systems as AI becomes part of the decision loop.
💡 While watching: Ask yourself: What jobs are likely to evolve in the next 12 months because of AI?
One Data Story
📊 Roughly 400 million terabytes of data are created every day.
When you see a stat that big, the obvious question is not “How do we collect more?” but “How do we use what we already have?”
To give you perspective of how big is that number, it is the equivalent of:
🏙 120 million HD movies uploaded every minute, or
📚 4 billion Libraries of Congress worth of information every 24 hours, or
💾 50 terabytes per person on Earth every year.
💡 Weekend challenge: Pick one dataset you or your team use. Ask: What percent of this data is unused, stale or non-actionable? Make one note to address that on Monday.
Going Forward
This five-item drop will hit your inbox each Saturday morning. A quick scroll, a few minutes of inspiration, and you are done. If you like this format (or want one of the items swapped in future such as quote, chart, mini-case study), hit reply and let me know.
See you Tuesday for the full-edition deep dive.
Have a great weekend.
