John Kerl reposted thisJob!John Kerl reposted thisWe’re hiring an AI Emerging Risks Analyst on my team at OpenAI! This is a rare opportunity to work at the frontier of AI safety, risk and strategy: identifying weak signals, analyzing how misuse and harms may evolve, and helping turn that understanding into concrete mitigations across products, policy, and safety systems. You’d be joining an excellent multi-disciplinary team and working with the amazing Sam Brannen! The right person is someone who enjoys ambiguity, thinks adversarially and strategically, writes clearly, and wants their analysis to have practical impact. If that sounds like you, or someone you know, please take a look and apply! https://lnkd.in/gDY3fv7k

One delayed salaries for months. One had a toxic manager he tried to tolerate for a year. He wasn’t switching jobs. He was protecting his sanity. Resumes show timelines. They don’t show survival.

John Kerl reacted on thisJohn Kerl reacted on thisLast week, I submitted my final assignment as an undergraduate student in the Honors College of Arts and Sciences at The Ohio State University. On Sunday, May 10, I will receive my degree in Molecular Genetics with a minor in Music. In completing this milestone, I would like to reflect on some of my achievements and opportunities of this past year. I continued my internship in the Maternal Fetal Medicine Office of the The Ohio State University Wexner Medical Center, where my excitement for becoming a Genetic Counselor grew. I am especially thankful to Laura Montgomery, Alexandra Wallenhorst, and Allison Spitale for their mentorship. They have taught me an unmeasurable amount about working as a genetic counselor, and I am very grateful for their efforts. I completed my final tour as a University Ambassador, giving 64 tours to prospective Buckeyes and dignitaries over the past two years. This role strengthened my public speaking skills and connection to the Buckeye Community. Thank you to Eric Hildebrandt and the Undergraduate Admissions team for such a meaningful experience. It has been a pleasure “walking backwards” with you all. My involvement with the Ohio Union Activities Board (OUAB) has been a cornerstone of my college experience. This year, I served as a Co-Chair of Community Engagement, working to foster connection and inclusivity within our organization and across the University community. I was honored to receive the Spirit of OUAB award, recognizing the student who brings the most positivity and energy to the organization. My time in OUAB has been unforgettable, and I am grateful to have been a part of it. Thank you to Candace Floyd, Annie Maxwell, and Alex Wenglein for always supporting me, and thank you to OUAB for shaping me into a more confident and effective leader. I would also like to extend my gratitude to the amazing professors and faculty who supported and motivated me along my collegiate journey. Thank you Dr. Melissa Shivers, Dr. Danny Glassmann, Matt Couch, Ph.D., Jeff Pelletier, Rebecca Sallade, MPH, CHES, David Swearingen, Dr. Eric Danhart, Dr. Steve Chordas III, Dr. Greame Boone, Dr. Christopher Callam, Dr. Noel M. Paul, and Dr. Heithem El-Hodiri. You had and will continue to have an immense impact on me, and I am grateful for your dedication to this University and its students. Finally, thank you to my family, friends, and Buckeye Community for your constant support and encouragement. I am proud of how far I’ve come, and I can’t wait to see what’s next.

John Kerl liked thisJohn Kerl liked thisI've spent 30 years in software engineering, and I'll say the shift happening right now is unlike anything I've witnessed in my career. I've been posting about AI-driven development for two years now — early adopter, true believer. And what's unfolding feels a lot like when we left assembly behind for higher-level languages. Nobody looked back. Yes, the layoffs are real. Productivity gains do that. But here's what I keep reminding myself, more jobs are coming, just different ones. Problems that were dead on arrival a few years ago — too expensive, too complex, no ROI — are suddenly solvable. Whole new categories of work are opening up. If you're a developer, learning to build with AI isn't optional anymore. It's the baseline, the data structures in 80s. #Claude #Cursor #Copilot #Gemini

John Kerl reacted on thisJohn Kerl reacted on thisSoftware development in 2026 is so deeply broken. You can't move fast because everyone looks at the diff between what was there before and what's there after, and every change will look completely unreviewable from that perspective. It doesn't matter if you have built up a mental model in your brain and write it down, nobody will read what you write in the PR description anyways, people will just put the diff into Claude instead and complain about there being so many changes. Every major design improvement or rewrite is now indistinguishable from slop You can't move slow and intentional because everyone expects 10x the output, and if you don't deliver there will be consequences Eventually it gets so frustrating that you need to resist the urge to just copy and paste every PR comment into Claude and completely give up on pushing back on reviewer's change requests/personal preferences/defending your own changes Something has to change. This is not sustainable. I don't think anyone knows how to fix this yet.

John Kerl reacted on thisWhen I started in this field 10 years ago, a place like Tech Coalition in existence would have felt like a fantasy. I first joined Online Safety at Facebook as a child safety investigator in Rita Fabi's and Karine Miller's team. We were deep in the casework related to content sextortion of minors, livestreaming, grooming, traveling sex offenders, NCII, but there wasn't much attention to it company wide, let alone industry wide. The trust and safety function was barely known internally outside of our direct partner teams. We didn't talk much about what our work actually was until years later. It felt daunting to explain my field even to my husband and my parents. Day to day, this work can feel thankless, bottomless, easily misunderstood, discouraging, and downright depressing. The days feel long and the years feel short. Now that I have the opportunity to consult at Tech Coalition it’s amazing to realize how much the scene has changed, how much more vocal and unified the industry is in combating online child sexual exploitation and abuses. How much more scrutiny there is from all sides (including internally) to hold companies accountable to child safety. There is always so much more to do, more to discuss, more to challenge the status quo, more and better fit solutions to figure out. When looking back where the industry is today compared to 10 years ago (not sure if there was even an online trust and safety industry at the time), it is a humbling reminder that this work is a marathon, not a sprint. Every inch counts. And every one willing to be part of the run makes a difference. Read where the industry is going and how it is working together to combat online child sexual abuses. It's a checkpoint, not a destination. And it's wonderful meeting other runners along the way.John Kerl reacted on this317 child safety improvements in one year. That’s the level of progress the tech industry is having in the collective fight against online child sexual abuse. In 2025, our 60 member companies strengthened how platforms prevent, detect, and respond to harm — across products, policies and operations. And it’s translating into outcomes—Lantern has now supported 350K+platform enforcement actions against accounts, URLs, and content. The threats are evolving fast. But so is the response. 🔗 Explore our 2025 transparency report, published today → https://lnkd.in/eiQPKrYr #Industrycollaboration #Trustandsafety

In case you missed it when the episode dropped, I was recently on the Crossword podcast. I finally had a chance to write a bit about our conversations on my site. We covered a lot of ground, including the concept of active versus passive contribution, how to find the appropriate balance between those two groups, the importance of being prepared when new contributors show up, and the nuance between a do-ocracy and a meritocracy. I'd love to hear your thoughts after you listen! https://lnkd.in/evmRqabE

Anthropic’s new Claude Sonnet 4.6 promises Opus-level coding at Sonnet pricing Anthropic on Tuesday launched Claude Sonnet 4.6, the latest version of its mainstream model. This new version promises to almost match the company’s flagship Opus 4.6 model, which launched barely two weeks ago, in most tasks, but at the significantly lower price of $3/$15 per million input/output tokens (compared to $5/$25 for the Opus model). Just like the previous version and Opus 4.6, Sonnet 4.6 offers a 1-million-token context window in beta.

As COO at www.jaiinfoway.com this is an important signal for where agentic AI is heading. Non technical implementations are catching up fast but the real story is iteration speed and learning loops. Building Cowork entirely with Claude Code shows how agents are becoming first class workers not just assistants. At www.jaiinfoway.com we see this shift clearly as enterprises move from copilots to autonomous task execution with guardrails. UX will evolve tooling will mature but the direction is set. Curious how others here see non technical users adopting agent driven workflows this year. Are we ready for agents as coworkers. #Jaiinfoway #AgenticAI #Claude #AIAgents #EnterpriseAI #FutureOfWork #AIProductivity #AITransformation #AILeadership

POV: It’s 2026 and your manual infrastructure is a ticking time bomb. 💣 If you’re still running terraform apply from your local terminal, we need to talk. Production-grade IaC isn't just about "making it work"—it’s about making it unbreakable. The 2026 Playbook for Terraform Elites: 🔒 State Isolation is King: Local state is a myth. Use S3/GCS with DynamoDB locking. Separate your Dev/Prod states or prepare for a $100k "oopsie." 📦 Modular or Bust: Stop copy-pasting code. Build versioned modules. Pin everything. If a provider update can break your stack, your stack is already broken. 🛡️ Zero-Trust Secrets: Hardcoding passwords in .tfvars? Straight to jail. 🚩 Fetch them dynamically from HashiCorp Vault or AWS Secrets Manager. 🤖 Policy-as-Code (PaC): Don't just plan. Use Open Policy Agent (OPA) to auto-kill any PR that tries to open Port 22 to the world. Stop clicking buttons. Start scaling logic. 🚀 What’s your #1 Terraform "lesson learned" the hard way?

I've always found myself switching to Claude models when working through coding problems. There's just something about how Claude handles context and works its way through large code bases and complex logic. With Claude Code, that workflow has become ridiculously smooth. Also been experimenting with OpenAI's Codex (GPT-5 powered) and the results are way better than previous versions. The code generation quality has taken a real jump. Now here's where it gets interesting. You keep hearing stories about developers opening multiple coding agents, feeding them the same task, and manually cross-referencing outputs to find the best solution. Turns out there's an easier way. By integrating Codex as a skill inside Claude Code, you get insights from both agents in a single terminal session when you need. No tab switching, no copy-pasting, no manual comparison. Claude Code orchestrates the workflow while Codex brings its strengths. Best of both worlds in one window. Claude OpenAI

Just published a new blog post on how engineering teams can “shift down” compliance into platform abstractions. I share thoughts on compliance leverage, OSCAL components vs capabilities, and how platforms can carry the heavy lifting for controls like TLS and mTLS—freeing developers from duplicating effort.

Check out this short, clear, and helpful video by Matt Pocock on using the Red -> Green -> Refactor approach of Test-Driven Development (TDD) with Claude Code. I've been using this approach, and find it to work really well. I'll be updating my workflow with Claude Skills to keep Claude Code more focused and not try to create too many tests at a time. Have you tried this approach?
