You’ll find both basic things every programmer should know (at least in theory – but let’s be honest, our memory isn’t perfect and we often need Google or AI), and some funny or surprising facts that even experienced devs will enjoy.
Whether you’re just starting out, have been coding for years, or just like clicking on smart-looking stuff – there’s something here for you.
Get ready for a smile, a few “ah, now I get it!” moments, and maybe even a “good to know!”.
WARNING: Side effects may include sudden coding inspiration and a strong desire to share what you’ve learned with every developer around you.
