Overflow, Underflow, and the Rise (and Fall?) of SafeMath in Solidityland

How I Learned to Stop Worrying and Love the CompilerAct I: The Ancient Times (Pre-0.8.0) — When Solidity Was Wild and DangerousBack in the dark ages of Solidity (before version 0.8.0), numbers in smart contracts behaved like toddlers with no adult supervision. Add uint256 + uint256? Sure, no problem — even if it wraps around like a cursed clock and silently goes from 2^256 - 1 to 0. Let me paint a scene:“Behold! My function mints 1000 tokens. Simple math: balance += 1000. But oh no — balance ...

ShambaTrack, Termites, and the Family Curse: How I Finally Gave In to the Call of the Soil

Jun 27
For years I tried to run from it. I mean, who willingly walks into the arms of agriculture when they’ve tasted the sweet, overpriced espresso of Nairobi boardrooms? Not me. Not willingly. Not at first. But then, my father was a forester. One sibling? An agricultural engineer. The other? An entomologist—yes, the kind who names insects like they’re pets and knows how termites argue during tea breaks. And me? I tried to be the digital rebel, the tech whiz, the urban warrior who never got cow dun...

He taught me everything I know about trees, plants, their hard names like Arborius Photosynthesicus Gigantimaximus (a tree that is huge and green) and their secret language. Did you know trees talk? No, seriously. Ever wondered why fresh-cut grass smells so good? That’s actually the grass screaming. Yep. That lovely scent isn’t just nature’s perfume; it’s an SO...

A New Kind of African Revolution – Now on Rarible!
fabian
Jan 25
Africa, a continent rich in culture, resources, and history, has long been misunderstood and exploited. For centuries, we were caught in cycles of oppression—slavery, colonialism, and a so-called freedom that often meant nothing more than the same old exploitation in new forms. Becoming an African leader in the 50s, 60s, or 70s was often the quickest route to a tragic end. Stories of death, poverty, and destruction was the main stay. But things are changing. Big time. Africa is ready to turn ...
