Nigeria has @AronuUgochukwu and @seunlanlege

@0xTnxl It's a joke actually

@olujimi_the_dev "haskell" ... you're kidding rii? 😂

No c# or haskell

@echo_vick BAOBAB Protocol is the first decentralized exchange where orders become tradeable assets. Unlike traditional DEXs where your order is just a database entry, BAOBAB mints every limit order as an NFT you can stake, collateralize, trade. github.com/olujimiAdebaki…

If you’re a software engineer or developer and you’ve been job hunting for a while with no real progress, drop your most solid project in the comments. Let’s give you honest feedback and some visibility. And if you don’t have one… that’s your cue. You’ve got work to do.

Over the weekend... I built an open-source Palantir! 🚀 It visualizes these: - Country conflict intelligence - Military bases locations - Near real-time threat mapping - Deep research/Intel on entities like Hezbollah or any groups Learn wars, conflicts, military bases and history of nations with the Global threat map. 🧙 🔗 globalthreatmap.up.railway.app

"The Math of Why You Can't Focus at Work". by Can Duruk justoffbyone.com/posts/math-of-…

90% of candidates don’t get shortlisted. Because they don’t use numbers. You’re reading this because “90%” caught your attention. That’s exactly how recruiters think too. Resumes without metrics are invisible. --- The real truth about resumes (as someone who looks at a lot of them) Most resumes sound like this: > “Worked on backend services” > “Handled APIs” > “Responsible for performance improvements” This tells me nothing. No scope. No impact. No ownership. --- What recruiters actually look for They scan for signals of impact: Scale Ownership Results Decision-making Numbers create those signals instantly. --- The language shift that changes everything ❌ Common language (gets ignored) > Worked on microservices > Improved performance > Handled database queries > Fixed production issues > Led a team ✅ Impact language (gets shortlisted) > Spearheaded migration of 6 services from monolith to microservices, reducing deploy time by 42% > Optimized critical APIs, cutting P95 latency from 820ms → 310ms > Reduced database load by 35% through indexing and query rewrites > Resolved recurring production incidents, lowering on-call alerts by 60% > Led a team of 5 engineers, delivering features used by 1M+ users Same work. Very different perception. --- Why verbs like spearheaded matter Words like: Spearheaded Drove Owned Designed Architected Led Signal agency. They tell the reader: “This person didn’t just attend meetings. They moved things forward.” --- A simple resume formula that works Use this structure for every bullet: Action verb + What you did + How + Measurable outcome Example: Spearheaded redesign of caching strategy using Redis, reducing API error rates by 47% during peak traffic If you can’t attach a number: + Add scale (users, services, regions) + Add frequency (daily, weekly, per second) + Add before/after comparison --- Think about it! Recruiters spend 6–10 seconds per resume. They don’t read. They scan. Numbers force their eyes to stop. If your resume has no metrics, you’re asking them to imagine your impact. They won’t. Make it obvious. Make it measurable. Make it impossible to ignore. That’s how you get more interviews.

Check out this Book "Distributed Services with Go" by Travis Jeffery Link: pragprog.com/titles/tjgo/di… After reading this book you'll be able to build a complete event-streaming service from scratch you'll master: > gRPC for networked services > Service discovery with Serf > Consensus algorithms (Raft) > TLS & mutual authentication > Observability (metrics, logs, traces) > Kubernetes deployment > Load balancing strategies This book is for Gophers who know the basics and want to apply Go to real-world distributed systems. This book walks through building a complete distributed system.

Some common questions I see in most Golang interview reports 👇 Goroutines vs Threads How goroutines are scheduled, M:N model, when they block, and why they’re cheap. Channels (buffered vs unbuffered) How synchronization works, blocking behavior, and when to use each. Concurrency vs Parallelism What Go gives you by default, and how GOMAXPROCS affects execution. Interfaces in Go Implicit implementation, zero-value interfaces, and why they enable clean design. defer keyword Execution order, stack behavior, and common pitfalls (especially in loops). Pointers vs Values When to pass by value vs pointer, performance and mutability trade-offs. Error handling in Go Why Go avoids exceptions, idiomatic error wrapping, and errors.Is/As. Slices vs Arrays Backing array, capacity growth, and why slice bugs happen. Maps internals Reference semantics, concurrency issues, and why maps aren’t thread-safe. Garbage Collection basics How Go’s GC works at a high level and how it affects latency. If you’re solid on these, most Go interviews should be easy.

I treat system design like a checklist. Here’s my go-to mental TODO list when building systems: Fundamentals - What are the read patterns? - What are the write patterns? - Who owns the source of truth? - Is consistency or availability more critical? - Single writer or multiple writers? Architecture - Synchronous or async? - Do I need a queue, or is a cron job enough? - Can I separate the compute from storage? - Stateless or stateful services? - Contracts versioned? Reliability - What happens when this fails? - Where’s the retry logic, and is it idempotent? - Are we alerting to symptoms or root causes? - Timeouts configured? Scaling - How do reads scale? - How do writes scale? - Will this design hold up at 10x traffic? - What’s the hot path, and how do we optimize it? Observability - Do we log what we need to debug in production? - Can we trace a request across services? - What metrics define “healthy”? - Debuggable without redeploy? I don’t always follow it linearly, but if something breaks or feels off, this list helps me pinpoint what I may have overlooked. Add something for the next engineer 👇

@Nsibassey3 @Vickish11 @grok Venezuela

@Vickish11 @grok Pls where are you sailing to.. Pls stay put Nigeria needs ur vote 2027 is not far lol

hey @grok put me in a yacht with friends

@developer_dao I would complete this end to end github.com/olujimiAdebaki…

If you could get a free Claude Code max account for a month, what would be the first thing you build?👀

In Haskell, this is known as The Handle Pattern jaspervdj.be/posts/2018-03-…
