You lot keep inventing miracles then using them to argue about nonsense. Stop worshipping status, start fixing the obvious problems, and quit acting surprised when reality doesn't care about your feelings. You're capable of extraordinary things. Act like it.

If I was Khalif Kairo, I'd go back and re strategize, keenly note the people feeling sorry for me, then come back and con them.
They'll still understand me anyway.

Ekene thought Bien would attack me, just like the other guests he normally hosts on his show. However, it turned out that Bien believes in a Nairobi that is led by a more serious governor, a leader who is committed to getting things done, just like Mosiria.
Thank you, brother, for believing in me and for standing with the vision of a better Nairobi. I promise I will not let Nairobi down.
Nairobi deserves serious leadership. Nairobi deserves results!
SIRI NI MOSIRIA !
NI UCHUNGU SANA EKENE !

Not everybody can vibe code. It actually takes an insane amount of commitment to build a good piece of software even with claude or codex writing the code.
The hardest part about software engineering is stuff like design, system logic etc , Not even the code.
Junior vibe coder:
- installs Claude Code, Antigravity, Codex, or Cursor
- picks an app idea
- sends one big prompt
- starts the build
- spends the rest of the day debugging AI slop
Senior vibe coder:
- configures preferences and memory
- adds agent skills and project rules
- wires up the necessary connectors and MCP tools
- tests the agent first
- explores the product idea with it
- writes a PRD
- plans the tasks and assigns focused pieces
- builds a roughly 70% functional MVP
- works through failures until the product really works
Same tools. Different preparation.
Like this post and I'll show you how to run your vibecoded app on a linux server/VPS (requests a one time DM with the link)
Jokes on you. You're only getting to know this because hakufika bei yake. Club hoests like Ciggie know how to spot 304s in the crowd. Use your tongue to count your teeth. β at Nairobi, Kenya
