I asked ChatGPT for dynamic energy solutions... and my own website (Stroomwekker) was nowhere to be found. 😅
Turns out AI search engines can't even read half of the websites out there.
So I built a free scanner to test how bad it really is: 🧵👇

⚠️ Python packages are vulnerable to remote code execution via the same node2shell CVE-2026-111497.
You may be affected if you are using the Brotli library. Note this is a very popular dependency (⬇️100m/month)
Other major services likely affected. We will communicate ASAP when we are able to.
Aikido detects this. Patches available.

‼️ After PHP2Shell comes Node2Shell, a critical bug found by OpenAI's Codex Security that can let attackers run code in Node.js apps.
It was successfuly demonstrated on the official Node.js 24.22.0 image.
Node 20, 23 and 25 (all EoL) get no fix.

🚨 BREAKING: NOW JAVA IS FACING A CRITICAL SECURITY EMERGENCY.
Oracle has issued an OUT-OF-BAND security alert for a dangerous 9.1/10 vulnerability affecting Java and GraalVM.
And the most alarming part? Hackers could exploit vulnerable applications REMOTELY, without a password or ANY user interaction.
Here's what's happening:
→ CRITICAL 9.1/10 FLAW: CVE-2026-91403 affects Java's JSSE security component.
→ NO LOGIN REQUIRED: Attackers could potentially exploit vulnerable applications remotely without authentication.
→ SENSITIVE DATA AT RISK: Successful attacks could expose, modify, or delete critical application data.
→ MULTIPLE JAVA VERSIONS AFFECTED: Oracle lists affected releases across Java 8, 11, 17, 21, 25, and 27.
→ GRAALVM ALSO AFFECTED: Oracle confirms the vulnerability impacts multiple GraalVM releases.
→ EMERGENCY PATCH ALERT: Oracle released an urgent security update rather than waiting for its next scheduled patch cycle.
The list of critical vulnerabilities just keeps growing.
If you operate Java applications or servers, CHECK YOUR SECURITY UPDATES NOW.
Readers added context they thought people might want to know
CVE-2026-91403 is a JSSE certificate trust issue with eight compromised eMudhra intermediates having weak keys, enabling potential MITM on TLS if attacker intercepts traffic—not a direct remote exploit of Java apps or servers.

I highly recommend cloudflare's security audit skill: github.com/cloudflare/securi…
Run it on all your software. Run it with the free models. Use it even if you used a model to audit something - it will find much more things. Works in all agent harnesses and is model independent.

US: Tesla Roadster. EU: tethered bottle caps.
I made that joke too. But let me be serious for a moment.
Made in Europe.
Europe built it.
Others told the story.
The Web was born at CERN.
Linux in Helsinki.
Python in Amsterdam.
ARM, the chip in your phone and your Mac, in Cambridge.
DeepMind in London.
The first commercial microprocessor was designed by an Italian, Federico Faggin.
Every leading-edge chip on Earth is printed with ASML machines from the Netherlands.
Mistral trains frontier open models in Paris.
Hugging Face: French founders, although it is headquartered in New York.
llama.cpp, the engine of local AI, started in Bulgaria.
The first mRNA vaccine came from Mainz.
Europe doesn’t lack innovation.
It lacks a megaphone. 🤷🏻♂️
Innovation without narrative becomes someone else’s success.
This isn’t Europe vs. anyone.
I love innovation wherever it happens.
I just want Europeans to feel proud and optimistic about the future again.
Did I miss something relevant here?

🕹️ 谷歌刚开源了 ARTEMIS，能让 AI 像人一样拿着一台真 Android 手机点来点去。
8 月中旬才建的仓库，GitHub 上已经 1.2 万 star，一千三百多个 fork，在 Google Research 的 AndroidWorld 基准上跑出 99% 以上的任务完成率，那套题覆盖 20 多个应用、100 多个多步骤任务。
写过 Android 自动化测试的都知道那种折磨：一个登录流程要写几十行定位代码，界面一改控件就全废，脚本比功能本身还难维护。ARTEMIS 的路子是你用自然语言说要测什么，它靠元素索引去点，认不出来就退回坐标和视觉定位，跨应用的流程也能一路走完。
它原生带一个 MCP 服务，Claude Code、Windsurf、Antigravity 这类工具可以直接驱动手机，顺手把 Logcat 和截图收回来。赶时间就用每步三到五秒的快速模式，想跑长时间稳定性测试就换成执行前先核对目标、卡住了再交回来的那一档。另外它第一次在设备上跑任务时会装一个读屏幕布局的辅助服务，只在手机本地运行、不往外发数据，失败了就退回 UIAutomator2。
手机测试这件事，终于不用全靠人肉手指了。

Yesterday my Stroomwekker API went down ⚠️
It was because @neondatabase, via @vercel, ran out of my free usage 😔
No email from either of them 🤯
So I moved to @Cloudflare to run it for free 😁 with Workers, Cron, and D1 database 💪
