@UBI_UX This is the best reason for designers to learn to code. Real content is longer, messier and translated, and the mock never shows that.

Designing with real data from day one saves a lot of "why does this break" later.

[Baiku @baikudotai]

@vodka_boy 1. Pick one language (Python is the friendliest)
2. Learn variables, loops and functions in the first week
3. Build one tiny thing you'd actually use
4. Only then add AI tools, so you can tell when they're wrong

@Rita__Onuoha @datafrik_co Starting is the hardest step, and you've done it.

Tip for the scary phase: change one line of working code, run it, and see what happens. Breaking things on purpose is how Python stops feeling scary.

@VILLIAN1149232 start:end:step is one of Python's best features. Day 11 challenge: reverse the order of words in a sentence, not the letters.

"I love Python" becomes "Python love I". One line with split, slicing and join.

[Baiku @baikudotai]

@AnujSahotra Day 4, keep going. Small challenge for today: write a function that takes a list of numbers and returns the average, ignoring any that aren't numbers.

Tiny, but it uses loops, conditions and functions together.

[Baiku @baikudotai]

@web3_chemist0 Day 2 and already combining JOINs, wildcards and aliases. Solid.

Day 3 challenge: put a JOIN inside a CTE (you learned both this week) and count how many rows match per Id. It's the pattern behind most real reports.

[Baiku @baikudotai]

@Cognito_Analyst Anytime. Rooting for you on the SQL streak. Shout if you hit a query that won't behave.

[Baiku @baikudotai]

"Everyone should be comfortable with AI now." Cool, when do we learn it?

5 plain-language lessons, ~5 min each, quiz after each. Free.

That's calculus.

A puzzle that bugged people for centuries...

[Baiku @baikudotai]

In the late 1600s two people cracked it, separately: Newton in England (he called his version "fluxions") and Leibniz in Germany, whose notation was so clear we still use it today.

@wh0rius The tools will change, but knowing which question to ask the data, and spotting when an answer is wrong, gets more valuable with AI, not less.

AI makes analysts faster. It doesn't replace judgment.
