### AI overview

A backend developer describes investigating unexpectedly high CPU usage in a legacy PHP monolith at Yandex Food. By profiling the application with Perforator and its PHP support, the investigation examined why CPU consumption was unusually high and how the allocated capacity could be reduced.

### Source excerpt

Всем привет, меня зовут Миша, и я бэкенд-разработчик в платформе Яндекс Еды. Я уже рассказывал, как мы анализировали наш PHP-монолит и вынесли из него процессинг заказов, и с тех пор роль этого легаси заметно уменьшилась. Заодно туда стали писать гораздо меньше нового кода, релизы стали реже, и он спокойненько себе работал, не привлекая лишнего внимания. Так оно бы и продолжалось, но тут случилась повышенная нагрузка и необходимость зарезервировать побольше мощностей для беспроблемной обработки повышенного спроса. Монолит справился на отлично, но самое интересное случилось потом: возвращая выделение ресурсов к прежним значениям, я случайно обратил внимание, что RPS в пиковые вечерние часы как-то подозрительно совпадает с количеством ядер CPU, выделенных на весь монолит. Количество выделенных ядер, конечно, ещё ничего не означает, поэтому я полез смотреть реальное потребление процессорного времени, сложив CPU usage по всем подам. С помощью нехитрой арифметики я обнаружил, что 100% загрузки одного ядра приходятся на 2,5 RPS. Какое-то время я находился в состоянии глубокого изумления, после чего решил, что это никуда не годится, и отправился в увлекательное приключение на 20 минут. Немного спойлеров: дело оказалось далеко не только в PHP. Читать далее

### AI overview

The article presents Beeline, a system that enforces application-layer (L7) policies directly in the kernel using eBPF. It explains the latency overhead of user-space service proxies and reports that Beeline improves request latency by 46%, while eliminating the service proxy from the critical path for 89% of L7 policies in the wild.

### Source excerpt

Guest Post: While many L7 protocols are complex to parse, the logic needed to enforce L7 policies tends to be simple. For the vast majority (89%) of L7 policies in the wild, Beeline can eliminate the service proxy from the critical path.

### AI overview

An opinion article argues that LLM-assisted programming makes language choice less consequential, allowing developers to use unfamiliar or traditionally difficult languages. It focuses on growing interest in fast, small software built with Rust and Zig, while noting examples involving WebAssembly, Cloudflare, Vercel, and other demanding technologies.

### Source excerpt

One of the memes on Twitter is that "programming is solved now." I'm not sure to what degree it is, but one thing is pretty clear: the act of familiarizing yourself with a language no longer matters and some of the friction that mattered for humans does not matter for agents. As a result, LLMs make language choice much less consequential than it used to be. If you don't like the choice, you can seemingly rewrite it in another language and you can make it pick a language that you, as a programmer, are entirely unfamiliar with. Which in turn means that people can, and do, choose based on the marketing of languages much more. As a long-term Rust programmer I found it quite fascinating to see people now ship Rust code who previously might not have chosen it. I attribute at least one part of this to two recent vibe shifts: there is a lot more talk about wanting fast software, and about LLMs being exceptional at optimizing code without regressing behavior. Folks like Mitchell Hashimoto, Charlie Marsh, Jarred Sumner, Daniel Lemire and quite a few others always carried a certain level of obsession with fast and performant software and they also all happen to be receptive to agents writing code. Maybe as a result, or unrelated others are now joining in. That's because with things like autoresearch you don't even necessarily need to know all the tricks: you just need to put an agent on it -- though knowledge greatly helps! If you look around, there are plenty of projects that want to be fast and small, and they increasingly pick "hard languages". And it's not just Rust that is benefiting. Even Zig -- despite the fact that the creators and parts of the core community are pretty negative on the whole AI thing -- is too. For instance Cloudflare's new Artifacts service uses a pure-Zig Git-protocol engine, compiled to a roughly 100 KB WebAssembly module and Vercel released fx, a Zig coding agent advertised to be small and fast. From what I can tell, all these projects are largely LLM

### AI overview

Netflix describes the engineering lessons from building a real-time service-dependency map at scale. The system ingests streaming network-flow, IPC-metric, and tracing data to support topology queries while addressing production issues such as Kafka lag, memory pressure, traffic skew, and garbage-collection overhead.

### Source excerpt

By Parth Jain, Rakesh Sukumar, Yingwu Zhao, Renzo Sanchez-Silva & Nathan Fisher A deep dive into the engineering challenges of building a real-time service dependency map at Netflix scale: from streaming architectures and distributed aggregation pipelines to time-travel queries and the methodology that made it work. Introduction In our first post, we introduced the problem: engineers at Netflix needed a unified, real-time view of service dependencies to troubleshoot faster, understand blast radius, and navigate our distributed architecture. We described our multi-source approach, combining eBPF network flows, IPC metrics, and distributed tracing into physically separate graph layers that can be queried independently or merged into a comprehensive view. That post explained what we built and why. This post is about how, the engineering reality of building this system at Netflix scale. Here's the truth: the first version worked perfectly... in our local environment. Production was a different story. Kafka consumers fell behind. Instances ran out of memory. Some nodes received 100x the traffic of others. Garbage collection pauses consumed more CPU than actual business logic. What you'll learn in this post isn't a success story, it's a learning journey. We'll walk through the architecture decisions that enabled scale, the production challenges that tested those decisions, the optimization methodology that guided us through, and the lessons that apply to any distributed system. Along the way, we'll share the innovations that made it possible to process millions of flow records per second, reconstruct topology at any point in time, and provide sub-second query responses, all while maintaining near real-time freshness. Architecture Deep-Dive: Building for Streaming and ScaleStreaming-First: Why Real-Time Matters Traditional service topology systems use batch processing, aggregating data hourly or daily, then storing complete snapshots.

### AI overview

An Adyen engineer investigates Cilium CNI timeouts that prevented new Kubernetes pods from starting. The article attributes the issue to sequential connection-tracking-table garbage collection, which became a bottleneck under workloads involving HDFS, Trino, and short-lived Spark jobs.

### Source excerpt

By Jorrick Sleijster - Senior Data Platform Engineer, Adyen I was fully aware a year ago that a single configuration line could break the Kubernetes networking stack. But if they told me that leftovers from Kubernetes pods which terminated hours prior could block new ones from starting, I would have thought they were joking. In high-performance networking, 35 seconds is a lifetime. This was the latency required to iterate through our connection tracking table of 7 million entries at a maximum speed of 200,000 entries per second. At our 16-million-entry peak, this sequential lookup could take up to 80 seconds, leading to Cilium CNI timeouts preventing new pods from starting on affected nodes. We uncovered this linear-time behavior at Adyen by tracing syscalls, inspecting codebases, and analyzing eBPF internals. This investigation revealed how our varied workloads turned the connection tracking table's garbage collection algorithm into a critical bottleneck. Our setup: why we're different At Adyen, we run Cilium CNI across all our 100+ Kubernetes clusters. When we switched from Calico to Cilium, we knew we'd face challenges adapting it to our production workloads. Our production big data Kubernetes clusters have a unique usage pattern compared to the other Kubernetes environments within Adyen: Data extraction from HDFS. Our infrastructure relies on more than 500 datanodes. Trino represents one of our most demanding HDFS workloads, processing analytical queries against data stored on HDFS. Due to the distributed nature of HDFS, each file you download requires a new connection to any of these 500 nodes. Therefore, during peak hours, a single pod can produce approximately 50,000 connections every minute. Pod churn. Many pods we spawn on the Kubernetes cluster run batch jobs, such as Spark jobs. They stay around for anywhere from a second to a couple of hours. Wide variety of workloads. Some workloads are very CPU-intensive, like Spark pods executing complex joins and tra

On top of that, 0.44.0 brings new rule-language capabilities, a long-requested safety knob for the capture feature, JSON output for the --list family of commands, a substantial round of performance work on process tree lookups, and a wave of multi-thread safety fixes that lay the groundwork for the upcoming multi-threaded Falco architecture. During this release cycle, we merged: 60 PRs on Falco, including 14 release note-worthy changes 160 PRs on Falco libs, including 54 release note-worthy changes 16 PRs on Falco drivers, including 3 release note-worthy changes We upgraded libs to version 0.25.2 and drivers to 10.2.0+driver. We also ship falcoctl 0.13.0, the container plugin 0.7.1, and the falco-rules ruleset 5.1.0. Thank you to our maintainers and contributors. This would not have been possible without your support and dedication! To learn everything about the changes, read on! What's new? TL;DR Major features and improvements: Comparison operator list modifiers (oneof/anyof/allof) Hard limit on capture file size Stricter rule schema validation Backslash escaping in -o dotted key paths JSON output for the listing CLI commands Faster process tree lookups Multi-thread safety hardening Drivers: The kernel module pre-builds for this release are still being produced and will be available within a couple of days from the release. In the meantime, falcoctl can build the kernel module locally on the host. Drivers: new syscall, kernel 7.0, and BPF iterators Plugins: Container plugin fix for containerd v2.3.0 Plugin library path traversal hardening Event generator: Event generator: HTTP output and new suite namespace Rules: Updated ruleset (falco-rules 5.1.0) Kubernetes: Kubernetes Oper
