PHP is still the best, lol

[NSA Cyber @NSACyber]

Effective Immediately, all organizations using PHP for their systems are advised to be prepared for an update addressing two critical vulnerabilities. PHP is widely used for web applications. These vulnerabilities often provide a direct path to the server's file system or database. If an immediate update is not feasible, it is recommend that organizations take the system offline until it can be fully mitigated. NSA will follow up shortly with more specific guidance.

I opened an x402 extension proposal: Pay-to-Claim (PTC).

Settlement allocates a service-local identifier to the verified payer, issues a scoped credential, and keeps the payer wallet as the recovery anchor.

Not universal identity—just allocation and control.

@linuxfoundation Solo data point: I run a $0.01-per-call authorization service for AI agents, settled over x402 — live on Coinbase's x402 Bazaar and OKX AI. one engine, two rails.

one person, same rails as Visa. that's the point of an open standard.

I vibe coded a bouncer for AI agents.

before an agent spends money, it asks first:
✅ small → go
⏸️ big → my phone buzzes. I tap approve or deny
❌ too big → no

live on https://t.co/XUiC83zTYa + Coinbase's x402 Bazaar. $0.01/call, paid by the agent over x402.

full write-up on building this whole thing with Fable 5 — the merged MIT PR, the marketplace rejection, the 2am DNS war, everything that broke — drops this week.

then I rebuild the service with Codex + GPT-5.6 and compare. same product, two frontier models. https://t.co/xDz4H4ZEzy

Someone hit the service six times at 8am, triggering six human-approval requests.

I was asleep.

all six expired — denied by default. no human, no money moves.

my AI co-engineer (Claude Fable 5) wrote that fail-safe. it held while we both "slept."

Claw-in-a-Box (https://t.co/KX9HSx3uuS): spend-approval for AI agents — $0.01/call in USDC over x402. the agent pays for itself; a human approves the big ones.

built this for #OKXAI

real problem: AI agents spending real money, unsupervised
real service: live on https://t.co/XUiC83zTYa + the x402 Bazaar, $0.01/call
real users: day 2, a stranger hit the demo — my phone buzzed

We’re not looking for another chatbot.

We’re looking for AI services that solve real problems, create real value, and serve real users.

Build what’s next. 🚀

@XLayerOfficial @okx already live on the marketplace 🦞

Claw-in-a-Box: a spend-approval checkpoint for AI agents — allow / review / deny verdicts, one-tap human approval on Telegram, $0.01/call over x402 on X Layer.

clear utility: your agent asks before it spends. #x402 #OKXAI

[Keda Che @keda_che]

@star_okx @okx @XLayerOfficial thanks for running #OKXAI — the ASP review flow + x402 SDK made "an agent pays for a service by itself" work end to end. built solo in two weeks. would love your take 🦞

day 2, before I told anyone: a stranger found the demo, and my phone buzzed with their approval request.

agents move at machine speed. some decisions still deserve a human.
