Web3 Is Like a Cult Building Apps No One Uses

Web3 isn’t the future — it’s a sandbox for developers chasing decentralization dreams while the rest of the world scrolls past. The truth is, most Web3 apps are clunky, confusing, and wildly impractical for everyday users. We’ve hyped up wallets, DAOs, and NFTs like they’re revolutionary, but outside the crypto bubble, no one’s asking for any of it. Until Web3 stops building for itself and starts building for real people, it’s just noise dressed as innovation.

Tech Communities Are Failing and It's Our Faulty

Tech community management isn't just about organizing events — it's about creating a space where people feel seen, heard, and inspired.

From welcoming newbies to empowering seasoned devs, the goal is simple: build a culture of collaboration, growth, and shared wins.

Whether it’s answering a question, spotlighting someone’s project, or just showing up consistently — it all adds up.

Great communities don’t just happen. They’re nurtured.

My MTN Line Has Been Successfully Linked With NIN

Yesterday, I made a post about the steps I took to reactivate my MTN line after it was barred. You can read it here: https://afr.ng/4dd97fc4.I know that the NCC asked MTN to unbar those lines, but the issue is that lines without NIN linkage will still need to be reactivated at some point in the future.So why not save yourself the stress now and fully activate your line? This way, you won't have to queue at an MTN office later.After following all the steps in the previous post, I got a confirmation from MTN that my line has been successfully linked with NIN.

How I got my MTN Line Working Again

My line was affected as well.Note: Government asked MTN to unbar the lines, however, if your NIN is not properly linked, you might still get barred in future.

KEYBOARD SHORTCUTS FOR PC

Go - constant variables and const keyword

Programming languages have the notion of constants which means “variables that can not be mutated once declared and initialized”.Go also has almost the same meaning, but in a different context. To initialize a variable as a constant with a value of 10, we can do something like this:$$const DISCOUNT = 10$$In Go, constants mean “storing a literal to a variable”, this can be seen as a version of pattern matching in Erlang.[Literals in go](https://www.phind.com/search?cache=n05row4wk42ocrf4520s6vzm) are constructs that can create an instance of strings, numbers, booleans, composite structures, fun...

Time in Computer Systems

Learn how time tracking is implemented from the hardware.Time is a linear monotonically increasing value and to keep track of it, a system has to be powered to take note of every tick. For a microcomputer running an operating system that can go on and off, this means there is a need to constantly update time whenever the computer comes on, but that is not the case because of some intelligent mechanisms that computer hardware and operating systems use to keep track of the current time.## Real-Time ClockA [Real-Time Clock (RTC)](https://en.wikipedia.org/wiki/Real-time_clock) is an electronic har...

A normal year has 365 days, and leap years have 366, with an extra day in February.This is how to work out whether a particular year is a leap year:*A year is a leap year if it is evenly divisible by **4** ;****except** if that year is also evenly divisible by **100**;****unless** that year is also evenly divisible by **400**.*For more context,Is the year 2400 a leap year?:2400 ÷ 4 = 600 (Leap)2400 ÷ 100 = 24 (Not Leap)2400 ÷ 400 = 6 (Leap!)So the year 2400 is a leap year.But the year 2100 is not a...
