@nanahrii Happy for you

Vibe coders are getting sued.

People are shipping apps with real users and skipping the boring stuff that kills them.

A 20+ year dev shared the pre-launch checklist every AI builder needs.

I added what I learned after shipping 60+ apps at the agency.

Don't skip this:

1. Protect yourself, not just your app. The moment you collect user data you're in legal territory (GDPR, CCPA). Have a privacy policy. Know where user data lives.

2. Row Level Security. Without RLS, anyone can open DevTools and read your entire database. Supabase → Auth → Policies. Zero policies means your app is naked. 5 min to fix.

3. Test the failure path, not just the happy path. Wrong password 5x. Reset for an email that doesn't exist. Verification link clicked twice. Signup with an existing email. Catches 80% of auth bugs.

4. Security baseline in 2 min. Prompt your AI: "Review my app as a security specialist and make sure I have strong security headers and a solid baseline security posture."

5. OWASP. Prompt: "Review my app against OWASP standards and highlight vulnerabilities." This is where SQL injection, XSS and auth bugs actually get caught.

6. Client-side validation is UX, not security. Attackers disable JS and hit your API directly. Validate again on the server. Every time.

7. AI code leaks data in 3 spots: .env values in the frontend, API responses returning too much, secrets in logs. Prompt: "Check my app for credential or sensitive data leaks in frontend or API routes."

8. API keys in the frontend means game over. If it's in the browser, assume it's already taken. Move it server-side or proxy it.

9. Rate limits before someone burns your API bill. Cap every endpoint hitting a paid API. I've watched a Supabase bill jump from $20 to $200 in a day.

10. CAPTCHA on public forms (Cloudflare Turnstile is free) plus CORS locked to your domain. 10 min, kills bot floods.

11. Error messages that don't leak. "User not found", not "SELECT * FROM users failed". Log full errors server-side, show users generic messages.

Build fast. Just don't ship naked.

For my first post, I’m sharing a letter @NVIDIA signed on why open models matter.

AI will transform every industry, power every company, and be built by every country.

Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty.

The world needs both frontier closed models and frontier open models.

@yuzu_jpg @X Hello guys lets connect

[Insecurity KE @InsecurityKE]

SAD: When armed officers see a man with a disability as the easiest person to overpower, leadership has failed. Press briefings fade, but videos like these become history’s evidence. Shame on you MURKOMEN, IG POLICE AND GOK SPOKESPERSON #EndPoliceBrutality

@marryevan999 Openclaw

[Marry Evan @marryevan999]

CLAUDE IS CONTROLLING MY PC!

New update from Claude and now you can allow Claude to fully use your computer

I gave Claude $200, said that you can do anything you want on my PC, but you need to profit on Polymarket

2 hours later, it monitored each wallet on Polymarket for the ability to copytrade them

It filtered 10 best wallets and started copytrading through this bot

Firstly, it lost $50 triyng each wallet to understand capability of copytrading it

Then, finally decided on 2 and copytraded each, resulting in ~10 hours, I had $3K

Now I reinvest it and continue copytrading cause it's insane now what you can do with that.

You only need Claude + laptop + 1 hour/day.

Giving This Free for 24 hours. To get it:

1. Comment the word 'OpenClaw'

THEFT ALERT ;

Yesterday, I was travelling towards Eldoret around 7ish in the evening. Upon arriving GSU camp,Molo I happened to notice a young guy hanging on a trailer . What seemed like hitching a ride turned to be a theft . So I'm told they usually target the long distance trailers while wako hapo climbing zone and they somehow open the containers. It seems like a well coordinated plan as proboxes are always positioned to carry the stolen goods. Are authorities aware ? @NPSOfficial_KE
