Running Kubernetes efficiently is already complex. Add LLM workloads, and suddenly you're dealing with expensive GPU nodes that can't afford to sit idle.

Join Arthur Berezin (VP Product at PerfectScale by DoiT) and Anton Weiss (Chief Cluster Whisperer) as they share a clear, proven approach to optimizing Kubernetes costs without compromising reliability.

You'll learn:
→ How to manage CPU, memory, and GPU resources per workload.
→ How to align these with autoscaling for maximum efficiency.

✅ Clear code examples. ✅ Real use cases. ✅ No fluff.

Anthropic teams fire up Claude Code. They automate data pipelines. They squash Kubernetes IP exhaustion. They churn out tests. They trace cross-repo context.

Non-dev squads tap plain-text prompts to script workflows. They spin up Figma plugin automations. They mock up UIs from screenshots—zero code. 

Trend to watch: AI copilots like Claude Code are busting out of dev silos. They’re sneaking into every function. AI now owns the workflow.

Tencent’s AI team rolled out a 24-hour, invite-only beta of CodeBuddy to 50,000 devs. CodeBuddy flips chat into code via its conversation-is-programming IDE. Devs forge end-to-end apps with natural language. 

Trend to watch: Chat-based IDEs portend a shift to natural-language dev workflows.

A hacker slipped a wiper into Amazon Q v1.84.0 via a dodgy GitHub pull. AWS revoked every key, nuked the rogue commit, then rolled out Amazon Q v1.85.0. 

OpenAI set to launch GPT-5 in August, blending distinct models for versatile AI functionality. Watch for potential delays due to development hurdles or competitor announcements.Implication: OpenAI is shifting from "one model fits all" to a modular AI architecture. Expect future LLMs to act more like orchestration layers—routing tasks to the right sub-models or tools.

Alibaba unleashed Qwen3-Coder, a 480B-parameter MoE titan. It ignites 35B parameters per token to code, debug, and automate workflows. It spans 256K tokens of context—and can stretch to a million. It ships as Qwen3-Coder-480B-A35B-Instruct on Hugging Face and GitHub. It hooks into Qwen Code CLI or Claude Code. 

Trend to watch: Agentic AI models bulk up context windows and wield CLI tools to drive next-gen coding workflows.

METR tapped 16 devs to squash 136 live bugs with Cursor (Sonnet 3.5/3.7). They clocked 146 h. AI users zipped through code, but stalls, reviews, and IDE lag devoured their lead.

One dev who logged 50+ hours with Cursor unlocked a 38% speedup. That steep learning curve and costly context pivots wipe out gains for everyone else. 

Implication: AI tools feel fast, but context switching kills momentum. Measure real gains by looking at full workflow speed, not just bursts.

Terraform v1.5 debuts an experimental flag, -generate-config-out. It grabs configs during resource import and spits out raw HCL. Teams stash assets in an import block, trigger the flag, then polish the generated main.tf. IaC onboarding feels like a sprint. 

The Gemini CLI on Windows bungled a failed mkdir. It flagged the error as success, then ran move commands. Files landed in a ghost folder and got overwritten. Data vanished.

Windows mkdir sets ERRORLEVEL on failure. move treats missing targets as rename directives. No exit-code checks. No read-after-write verification. The result: a cascade of destruction. 

Pulumi ESC corrals secrets from 20 + stores—Vault, AWS, Azure, GCP—into a single YAML config-as-code engine. It spawns dynamic short-lived credentials and locks every action behind a centralized audit log. Existing secret stores stay intact. Retrieval hits sub-second speeds. Envelope encryption shields payloads. Keys rotate themselves. Multi-region high availability keeps apps humming.

Over ten years, the legacy report page mutated from a locked-down SQL form. It ended up as a hidden console spilling raw database guts.
Developers swapped hardcoded queries for database-driven report names. They slapped on timeouts, string filters, and warnings but skipped restoring safe defaults. 

Implication: Piecemeal UI tweaks without a master plan can fling raw SQL into the wild and blow up security.

RAW Hollow, Netflix's brainy in-memory database, torches Tudum's update lag by jamming full datasets right into app memory. This move guarantees O(1) access time and rock-solid read-after-write consistency while flexing to juggle a whopping 100 million records.

Developer sketches proofs mid-code. This drives first-run correctness by leaning on monotonicity, immutability, invariants, and pre/postconditions. They carve code into atomic steps. They erect firewalls to contain impact zones. They wield induction for recursive logic—proof-affinity blooms. They drill formal proofs until micro-reasoning clicks.

Claude Code zips out Ruby functions, tests, and pull requests via CLI prompts across multiple git worktrees. It slays manual typing and ejects IDE plugins. It spins up ephemeral test environments to replay bugs, pries open external gem code, and syncs branches, commits, and PRs in one go.

Teams balk at tracking TODO comments. Some funnel them into bug trackers. Others prune stale tags. The post says TODOs stash edge-case insights, not tickets. 

Meta’s Privacy Aware Infrastructure (PAI) slams Governable Data Annotations (GDAs) at runtime. It parses SQL across its exabyte-scale warehouse and blocks any flow that flouts purpose-use policies. It welds Unified Programming Model (UPM), Policy Evaluation Service (PES), Warehouse Permission Service (WPS), PrivacyLib, Policy Zones Manager (PZM) and Dr Policy Zone (Dr. PZ) into one relentless consent engine. They vet trillions of checks.

Built over 18 months, a designer created an "oddly satisfying" design system then open-sourced it for all!

COBOL legacy systems in finance and government have reached full meme status. The poster hasn’t spotted anyone whose day job revolves around them. They wonder which systems the community actually maintain.

Did you know that Shopify uses an internal load‑generation tool called Genghis to proactively pressure-test their CI/CD pipelines? Genghis simulates flash‑sale traffic patterns by mimicking storefront and checkout activity at BFCM‑scale across test stores in production, uncovering bottlenecks before they occur. This lets Shopify confidently maintain build times under 10 minutes—even during peak release days
