AWS Lambda now natively supports Avro and Protobuf formatted Kafka events, dancing through schema chaos with Glue and Confluent registries. Toss custom deserialization in the trash; plug in Powertools and let open-source Kafka consumer interfaces do the grunt work.

AWS VPC lets your inner network architect cheer: 500 routes per table now. That’s a cool 10x boost from before, turning network scaling from a headache into a child's play. 🚀

Lenovo's ThinkSystem SR680a V4 doesn't just perform—it explodes with AI power, thanks to Nvidia's B200 GPUs. We're talking 4nm chips with a mind-boggling 208 billion transistors. Boost? Try 11x.

Terraform AWS Provider 6.0 bursts onto the scene with multi-region support. Now, devs can tweak 32 config files in one shot, slimming down memory bloat. 🌍💻

Graviton throws a wild price-performance party, but AWS CLI/API leaves you hanging on fallback strategies. So, we conjured a Terraform ASG stunt: dual launch templates that smoothly swap between ARM and AMD. Multi-arch Docker images save the day, grabbing the right variant and dodging cluster bedlam. Who knew code could dance?

Observability 3.0 charges headlong at the ballooning fees of system monitoring. Companies throw down more than $10M a year on this jungle. But this version doesn't settle for the old, bloated ways. Instead, it's a sniper: precise telemetry, clever data maneuvers, cost-cutting without skimping on insights, and none of that useless data clutter.

OpenTelemetry puts you in the driver's seat, letting you modify span attributes with custom processors or hooks. Need to slip in an S3 bucket name? Easy. It's almost like a secret handshake for data.

Google Cloud's Migrate to Virtual Machines tool whisks away your Amazon EC2 instances to Compute Engine. It handles replication and the final cut-over like a seasoned magician—no fluff, just action.

Each week, we’ll spotlight one person from our community — a developer, DevOps engineer, SRE, AI/ML/data person, open source maintainer, or someone building cool things behind the scenes.

We’ll share who they are and where you can follow or connect with them. Not a sponsored feature. Just good people doing good work!

jemalloc excels at sniffing out memory leaks compared to AddressSanitizer, especially when leaks ghost out at program exit. But here's the catch: to dig into profiling with jemalloc, like you're wrangling Postgres, you better cozy up to Linux.

Developers chase promotions, not the tedium of deployments. Environments should reign supreme—not just a lone Kubernetes cluster hogging the spotlight. Real-time insights? They zoom past those outdated, siloed CI pipelines.

Tired of losing terminal sessions and scrollback with tools like tmux, screen, or mosh? A new tool called alden keeps your SSH shell alive after disconnects without breaking your native terminal scrollback. Unlike other solutions, it avoids emulating a terminal—so you get seamless reconnection and keep your scroll history intact.

Impulse lets Airbnb teams wreak havoc in the best way possible. It makes load testing in Java/Kotlin a breeze. No need to call in the cavalry. It just mocks what it needs to and spins up a frenzy of pseudo-real traffic.

GitOps has taken the throne, with Git as the undisputed oracle for configurations. Welcome to a world where Argo CD and Flux strut their stuff. By 2025, this lively dance of pull-based magic reshapes the landscape. GitOps isn't just a tool anymore—it's a full-blown, no-holds-barred platform transformation.

Migrating to AWS Graviton with Java 21 didn't just pinch pennies—it saved 20% and cranked up performance. Why? The magic of ARM64 support and multi-arch CI/CD. They navigated the switch by harnessing dual-architecture EKS clusters and canary deployments. Result? A smoother path with zero hiccups. End users? Oblivious but delighted.

Rust’s compiler speed has doubled in three years for some benchmarks. Remarkably efficient. But its intricate architecture still wrestles with progress. Stability hogs the spotlight, and new features waltz in, leaving optimizations to grab scraps. Volunteers—Rust’s lifeblood—fuel much of its growth. They crave evolution. Unfortunately, faster builds might require tossing old ways and betting on bold, sweeping changes. Stay tuned.

Lock down Terraform like Fort Knox. Verify your module origins. Guard sensitive state data like a nosy neighbor's business. And, please, no hardcoded credentials—rookie mistake. For ironclad security, pin those module versions, tap into private registries, and wield the power of dynamic provider credentials with OIDC like a pro.

GitHub bots like Dependabot might merge malicious code due to "Confused Deputy" attacks, escalating to command injection via crafted branch names. New TTPs reveal clever ways attackers exploit these issues.

Throw automatic rollbacks out the window. You don't need them. Continuous Delivery partnered with human-driven resilience sharpens up your software. When things go sideways, a speedy roll forward with a clever fix beats a blind retreat. Automatic rollbacks? They skip the surprises and rob you of learning moments, not to mention the backward compatibility headaches they might unleash.

Data Analysts sift through the past using SQL and BI tools. Their goal? Unearthing insights. Meanwhile, Data Scientists harness the power of Python and R to gaze into the future—predicting trends like data-driven oracles. On another front, Data Engineers craft pipelines. Think Apache Spark—the stage manager for data's grand entrance, ensuring it marches smoothly. Then there's DevOps, the maestros of app delivery. Pitching them into MLOps and expecting perfection? Asking a fish to climb trees sounds equally plausible.

Microsoft's shiny SRE Agent wades into network snafus with swagger but makes some bold, perplexing claims—like leaning on faulty data insights for fixes. Slick demos dazzle, yet its "approve and act" zeal might lure newbies into rash decisions. Handle with care!

Will's BugBash talk explored how engineers can build better software by combining testing and observability. While testing finds issues before deployment and observability monitors live systems, Will asks: what if you could simulate production chaos without real-world fallout?

YAML command executor

A fast, rule-based CLI tool for organizing files.

ServBay is an all-in-one localized web development environment that simplifies and accelerates your web projects.

Build complete API integrations with YAML and SQL. Rapid development without vendor lock-in and per-row costs.

GitHub’s main Rails monolith—run by tens of thousands of tests—relies on its open‑source Scientist gem (introduced around 2014–2016) for safe production-level refactoring. Rather than swapping code wholesale, Scientist executes both old and new code paths in production, silently comparing results under real load. Only when the candidate code matches in output and performance does GitHub fully adopt it—mitigating risk in critical system updates without disrupting developer workflows.
