@Polymarket Holy shit. Polymarket posted about us

JUST IN: South Africa pulls its AI policy draft after it was revealed to contain fake AI-generated sources.

25 signs your VIBE CODED app will BREAK at 500 users : Save this before you go live ! 1/ no load testing before launch > you don't know where it breaks because you've never pushed it > one traffic spike and you're debugging live in production 2/ session data stored in server memory > works on one instance > breaks the moment you need two 3/ file uploads going directly to your app server > disk fills up. server dies. files lost. > move uploads to object storage on day one 4/ synchronous email sending in API routes > slow email provider = slow API response for every request that triggers one > offload to a queue. always. 5/ no queue system for background tasks > everything blocking > one slow task pauses everything behind it 6/ hardcoded secrets in deployment scripts > sitting in your CI logs > visible to anyone with pipeline access 7/ single database with no read replica > all reads and writes hitting one machine > first real traffic spike kills query performance 8/ no CDN in front of static assets > every image served by your app server > 500 concurrent users = 500 image requests hitting your backend 9/ DB migrations running automatically on app start > two instances deploy at the same time > both run migrations. race condition. data inconsistency. 10/ no database backup ever tested with a restore > you have backups > you've never actually restored from one 11/ unindexed foreign key columns > every JOIN is a full scan > slow at 100 rows. broken at 100,000. 12/ no rate limiting anywhere > 500 users. one of them is a bot. > your server is now a bot server 13/ API responses with no compression > JSON payloads sent uncompressed > 10x the bandwidth they need to use 14/ no error alerting configured > app crashes at 3 AM > you find out when a user emails you at 9 AM 15/ transactions not used for multi-step writes > step 1 succeeds. app crashes. step 2 never runs. > data is now inconsistent permanently 16/ health check endpoint missing > load balancer sends traffic to crashed instances > users get 502s. you get support emails. 17/ memory leaks in long-running processes > memory grows slowly. server hits 100%. > everything grinds to a halt. restart. repeat. 18/ no graceful shutdown handling > deploy kills active requests > users mid-action get errors with no retry 19/ dependent on a third-party API with no fallback > that API goes down > your core feature goes down with it 20/ all logs written to local disk > logs rotate off > incident happens. no history to debug with. 21/ no circuit breaker on external calls > external service is slow > your thread pool fills waiting for it. everything queues. 22/ unparameterized search queries > search with any real data volume > 5-second response times at scale 23/ no connection timeout on outbound HTTP calls > external API hangs > your thread hangs with it. indefinitely. 24/ WebSockets not handled by a stateful service > horizontal scale breaks real-time features > every user gets disconnected 25/ no runbook for common incidents > something breaks at 2 AM > nobody knows what to do. everyone panics. you can ship fast and still build something that holds. bookmark this before you go live.

Water is the New Land! WC & KZN farmers had this figured out!! ​Historically, land was the primary measure of wealth. In a semi-arid future, water storage is the new title deed. ● ​State Bulk Water Sales: Est. R14.8 billion (2026/27). ● ​Private Dams: These are now core balance-sheet assets, yield insurance, and drought buffers. ​The Western Cape’s 1,500 dams and KZN's 1100 represent decades of deliberate private capital allocation.

@SemudaraAbayomi Bolt and uber aren't in Nigeria anymore?

Beyond food delivery, they have plans to become a super app with payment and other services embedded… It remains to be seen if their model will work or they will fail in the market that has seen Bolt and Uber Foods gone..

In February 2026, Nigerian consumer Dolapo Adedeji filed a lawsuit against Chowdeck over alleged lack of pricing transparency. SWOOP announced their $7 million dollars raise and expansion to Lagos, Nigeria with an interesting proposition. Transparent pricing… 100% delivery fees go directly to its riders, the company charges 7% service fee to cover operations. 🧵🧵🧵

@Side_To_Cide What prototypes? I'm curious. Please tell me more

Nathi siyabuza, bhuti. My prototypes are gathering dust as we speak. Seed-funding is a bedtime story kuthi bamnyama.

🇿🇦 South Africa just made history. The CSIR has cracked the code on producing the critical molecules needed for lab-grown meat — CSIR has scaled up production We no longer need to import expensive starter chemicals from the US or Europe. SA is now one of the few countries on Earth that can grow its own protein. 🥩🔬 Why Is It a Big Deal? ​● It eliminates the need for large-scale animal slaughter. ​● It uses significantly less land and water than traditional cattle farming. Would you eat lab-grown Meat?

No employees? What is she "building @ nomandtable"?

@peacendlovu_ Why did you opt for the sedan over the hatch?

BMW M3 g80 2025

@MotionLonelines @rive_app Do you have an MCP?

What if your app mascot could eat, sleep, and change color on demand? Built this cat character system in @rive_app state machine driven, Perfect for apps that need a little personality. 🐱

@tumietumieza "what a time to be an academic" because of a tweet? Ffs. The bar is in fucken hell

@mboendlov Yeah. So?

The comments about Lesotho are disgusting & reek of emperialism

Vibe Coding Robotics Part 10 Added a secondary camera focused on the gripper Next : generating CAD scripts to explore more advanced gripper mechanisms Code : Gemini 3.1 Pro Design : Nano Banana

That 26-year-old Steve Jobs energy was something else.

@HowThingsWork_ W Engineering!

A motoGP racing suit can exceed $10,000 in costs & feature an airbag that inflates in less than 45 milliseconds 💨

@adriamatz Thanks for the daily sauce, brother!

This is how Learna hooks 2M users/mo into paying $14.99/week: Onboarding flow: • App Store ratings + millions of downloads shown upfront (social proof) • Pick your language → shows you can learn any of them • "Just 15 min a day" (removes the commitment fear) • Live test: you actually talk to the AI during onboarding • Asks about your hobbies, goals, available time • Fake "preparing your plan" loading screen (you're already invested) Paywall strategy: • 7-day free trial (lowers the barrier) • Only one plan: $14.99/week (no annual option) • That's $60/mo for a ChatGPT wrapper • No choice = no decision fatigue = higher conversion Steal this for your next app.

STARTING OVER MY PREGNANCY APP Got hit with multiple Apple rejections. First app ever built, made a lot of mistakes At this point it’s faster to rebuild than fix Timeline: 1 week UI, features, everything is already done This will be a lot faster Learned everything I needed the hard way. This one gets approved No doubt Social media Pages are already pulling millions of views. First 100 users will be easy. I’ll share everything

@VeeWasTaken #Washed

@F1SaturnV Yea it was good from hadjar

This is about MV33, is it not? That he can take a tractor across the finish line, now that he has one, let him do it

@autosport Nothing to do with respect. He was asked a simple question and it seems it touched a nerve. You might say he was triggered and he’s holding a grudge. But, let’s talk about respect. Is parking your car on another driver’s head and walking away without a care respectful?

@VeeWasTaken x.com/F1BigData/stat…

@F1SaturnV Its not about mv33 its about mv3.
