@TheDarkHumours I would unplug the gas line and hop out and tube. Then one of my friends tried it and forgot the gas line part. We couldn’t hold on and bye bye boat. Stay tuned for the rest of the story.

AWS just launched a preview of full-repository code scanning in AWS Security Agent — and it's not just another static-analysis tool. This capability uses AI to perform deep, context-aware security analysis across your ENTIRE codebase. We're talking about a system that doesn't just flag suspicious lines — it can find vulnerabilities AND build working exploits to prove they're real. That's a significant leap forward.

🎯 Certification relevance: This directly touches domains covered in the AWS Security Specialty & Developer Associate, specifically around threat detection, secure coding practices, and AI-powered security tooling.

🛠️ Real-world scenario: Imagine a Solutions Architect designing a CI/CD pipeline for a fintech client. Instead of waiting for a post-deployment penetration test, AWS Security Agent scans the full repo during the build phase, surfaces a critical injection vulnerability with exploit context, and the team remediates before a single line hits production.

A recent grad reveals 6 things university doesn't teach you about working with data:

👩🏻‍💻 Data cleaning isn’t a preprocessing step. It’s the job.
👏 Stakeholder trust is a technical problem.
😯 The questions that matter most aren’t technical.
🚅 Speed matters more than perfection.
📜 Documentation isn’t busy work. It’s how teams stay aligned.
🎓 Speed of learning matters more than current knowledge.

AI jobapalooza!

[Andrew Ng @AndrewYNg]

There will be no AI jobpocalypse.

The story that AI will lead to massive unemployment is stoking unnecessary fear. AI — like any other technology — does affect jobs, but telling overblown stories of large-scale unemployment is irresponsible and damaging. Let’s put a stop to it.

I’ve expressed skepticism about the jobpocalypse in previous posts. I’m glad to see that the popular press is now pushing back on this narrative. The image below features some recent headlines.

Software engineering is the sector most affected by AI tools, as coding agents race ahead. Yet hiring of software engineers remains strong! So while there are examples of AI taking away jobs, the trends strongly suggest the net job creation is vastly greater than the job destruction — just like earlier waves of technology. Further, despite all the exciting progress in AI, the U.S. unemployment rate remains a healthy 4.3%.

Why is the AI jobpocalypse narrative so popular? For one thing, frontier AI labs have a strong incentive to tell stories that make AI technology sound more powerful. At their most extreme, they promote science-fiction scenarios of AI “taking over” and causing human extinction. If a technology can replace many employees, surely that technology must be very valuable!

Also, a lot of SaaS software companies charge around $100-$1000 per user/year. But if an AI company can replace an employee who makes $100,000 — or make them 50% more productive — then charging even $10,000 starts to look reasonable. By anchoring not to typical SaaS prices but to salaries of employees, AI companies can charge a lot more.

Additionally, businesses have a strong incentive to talk about layoffs as if they were caused by AI. After all, talking about how they’re using AI to be far more productive with fewer staff makes them look smart. This is a better message than admitting they overhired during the pandemic when capital was abundant due to low interest rates and a massive government financial stimulus.

To be clear, I recognize that AI is causing a lot of people’s work to change. This is hard. This is stressful. (And to some, it can be fun.) I empathize with everyone affected. At the same time, this is very different from predicting a collapse of the job market.

Societies are capable of telling themselves stories for years that have little basis in reality and lead to poor society-wide decision making. For example, fears over nuclear plant safety led to under-investment in nuclear power. Fears of the “population bomb” in the 1960s led countries to implement harsh policies to reduce their populations. And worries about dietary fat led governments to promote unhealthy high-sugar diets for decades.

Now that mainstream media is openly skeptical about the jobpocalypse, I hope these stories will start to lose their teeth (much like fears of AI-driven human extinction have).

Contrary to the predictions of an AI jobpocalypse, I predict the opposite: There will be an AI jobapalooza! AI will lead to a lot more good AI engineering jobs, and I’m also optimistic about the future of the overall job market. What AI engineers do will be different from traditional software engineering, and many of these jobs will be in businesses other than traditional large employers of developers. In non-AI roles, too, the skills needed will change because of AI. That makes this a good time to encourage more people to become proficient in AI, and make sure they’re ready for the different but plentiful jobs of the future!

@sooyoon_eth Good point. With security you have to protect each layer. The repo is a good place to start, but yes, not enough.

[John Krull @johnkrull]

AWS security agent can automatically scan your whole code repository for vulnerabilities!

Perhaps going under the radar is Jeff Bezos' AI startup, Prometheus. Its models are based on images and video and not language. The target audiences are manufacturing, supply chain, and industries where language doesn't accurately describe the process. Built-in does a nice deep dive. https://t.co/N3bv5PSgFr

Khan Academy, TED, and ETS are starting a new program to equip students and professionals with the skills to thrive in an increasingly AI-driven economy. It's a $10K "AI School" that promises to future-proof your career. Is it a threat to HigherEd? Is it a good choice for a gap year? Something to do while on unemployment? https://t.co/4mKkC4EcEy

@QuinnyPig good take on this integration

[John Krull @johnkrull]

Native integration with Claude platform on AWS opens up a great option.

[Matt Garman @mattsgarman]

We're the first cloud provider to offer @AnthropicAI 's native Claude Platform directly through customer accounts. Teams get access to the full platform, from Managed Agents to code execution, using the @awscloud credentials, billing, and audit controls they already rely on.

No new vendor accounts, no new systems. https://t.co/I9w1ypzhXH
