### AI overview

Pulumi is launching the Context API, a read-only API that connects Pulumi-managed and discovered resources, stacks, and their relationships into a graph. Available in public preview for Enterprise and Business Critical organizations, it supports infrastructure-impact, coverage, and cleanup queries through the Pulumi CLI or REST API. Pulumi Neo uses it out of the box, and other authenticated agents can access its schema and query guidance.

### Source excerpt

Every platform team fields the same questions: What is running? What breaks if we change this? What can we safely delete? The answers exist, but they're scattered across state files, cloud consoles, and the memories of whoever set things up. Today we're launching the Pulumi Context API, a read-only API that connects Pulumi-managed and discovered resources, stacks, and their relationships into a graph. It's designed agent-first: Pulumi Neo, our infrastructure agent, uses it out of the box, and other agents can fetch the current graph vocabulary and query guidance on demand. It's available in public preview for organizations on the Enterprise and Business Critical editions. Answers that follow infrastructure relationships Pulumi already records the resources your programs manage, their dependencies, how stacks consume each other's outputs, and the resources Pulumi Discovery finds outside infrastructure as code (IaC). The Context API connects this data so you can ask questions that depend on the relationships: Impact: Which stacks are affected if we upgrade this provider? If this stack changes, what consumes its outputs? Coverage: How much of our infrastructure lives outside IaC, and in which accounts? Cleanup: Which stacks have no dependents and are candidates for retirement? A query is a JSON document with a handful of clauses. anchor names the starting nodes, traverse follows relationships from there, and return chooses what comes back. You can run a query through the Pulumi CLI or REST API. Here's a selector that starts from AWS provider instances older than version 7.0.0 and follows incoming provided_by relationships back to the visible resources they manage: { "anchor": { "nodeType": "resource", "match": { "type": "pulumi:providers:aws", "fields": { "provider_version": { "op": "lt", "value": "7.0.0" } } } }, "traverse": [ { "edgeTypes": ["provided_by"], "direction": "in", "alias": "managed" } ], "return": { "select": ["anchor", "managed"] } } A response for one m

### AI overview

This article explains how LLVM turns branch probabilities into per-block frequencies through linear-time propagation over loop-structured regions. It also notes that irreducible control flow reduces accuracy.

### Source excerpt

Estimating branch probabilities says how one branch splits. BlockFrequencyInfo turns those local numbers into per-block frequencies, which nearly every profitability decision in LLVM ends up reading. The core is a linear-time propagation over loop-packaged regions. Where no such structure exists -- irreducible control flow -- the accuracy goes with it.

### AI overview

A practical checklist for Kotlin K2 migrations in projects that generate or validate dependency wiring. It recommends mapping the compiler and build toolchain, upgrading from a known compatibility matrix, cleaning and inspecting generated output, verifying dependency graphs across flavors and targets, testing runtime slices, and keeping rollback changes coherent.

### Source excerpt

A K2 migration is usually planned around source compatibility and compiler diagnostics. Projects that generate or validate dependency wiring need another checklist: compiler plugin versions, generated sources, metadata compatibility, and graph verification on every target. Map the toolchain first Record the Kotlin plugin, Compose compiler plugin, KSP or annotation tooling, dependency-injection compiler plugin, Android Gradle plugin, and target libraries. Upgrade from a known matrix instead of selecting each latest version independently.

### AI overview

This tutorial recommends creating a framework-independent dependency-graph inventory before migrating dependency injection. It explains how to document entry points, ownership, implementations, lifetimes, qualifiers, modules, replacement values for tests, and architectural constraints, then validate the design through smaller executable test slices.

### Source excerpt

A dependency-injection migration often starts with framework syntax. That is too late. First describe the graph without using the framework's vocabulary. The inventory should show which objects exist, who owns them, and which runtime fact selects one implementation over another. Start from entry points List application entry points: the Android application, a worker, a navigation destination, a command-line process, and each test fixture. Trace the objects requested at each entry point. Stop the trace at explicit boundaries such as a database driver, HTTP transport, clock, file system, or platform service.

### AI overview

Razorpay describes its platform for running Hermes, an open-source AI agent, for employees. Each agent runs in an isolated Kubernetes namespace with encrypted storage, a separate cloud identity, and its own network policy. The article explains how the platform supports persistent autonomous sessions while limiting access to other employees' data and the public internet.

### Source excerpt

How we run a personal AI agent for everyone at Razorpay: always on, multi-model, and safe by construction. Contributors: Siddharth Tripathi Today, more than 220 Razorpay employees each have their own always-on AI agent. On a typical day, about 84 of them are actively working. Every one runs in its own isolated Kubernetes namespace, with its own encrypted storage, its own cloud identity, and its own network policy. It learns new skills as its owner works, and it keeps running long after they close their laptop: one employee's agent has already logged more than 15,000 sessions, 90% of them while its owner was asleep or away. Provisioning a new one takes under two minutes. Running the agents was never the hard part. Running them safely was: 220 of them, each with shell access and live credentials, without any single agent becoming a path into another employee's data or out to the open internet. The answer came down to one design choice, and everything in this post is a consequence of it: Isolation is a property of the infrastructure, not the application. Hermes itself is an open-source agent by Nous Research; what we built is the platform that runs it safely & isolated, for the whole company. Proof It's Real: One Instance, Eight Weeks In Before any of the architecture, here's the proof that people actually use this. The following is one real instance from our cluster, over its first eight weeks (numbers pulled live, the person anonymised). In eight weeks, this one user's Hermes ran 15,039 sessions. Only 391 of those were the person sitting down to chat with it; the other 13,570 were autonomous runs the agent kicked off on its own schedule while its owner was asleep or in meetings. That ratio is the whole idea in one statistic: the assistant does most of its work when you're not there. What is it doing in those runs? They'd wired up 21 always-on scheduled jobs that turn Hermes into a personal intelligence service: Ingest. Every hour it pulls from 23 Slack channels (plus

### AI overview

This technical post explains why dominator-based natural-loop detection fails for irreducible control-flow graphs, which can have multiple entries. It describes reducibility, the irreducible three-node pattern, and a DFS-based loop-nesting forest using Havlak's convention.

### Source excerpt

The dominator tree lets us identify natural loops: a back edge T->H whose head H dominates its tail T defines a loop with the single entry H. This works only for reducible control flow graphs. Optimized machine code and decompiler output routinely contain irreducible loops, which have more than one entry and thus no dominating header, so the dominator-based method cannot see them. This post builds a loop-nesting forest for an arbitrary CFG with the single-pass depth-first search of 韦韬、毛剑、邹维、陈宇(Tao Wei, Jian Mao, Wei Zou & Yu Chen) A New Algorithm for Identifying Loops in Decompilation, SAS 2007 (The 14th International Static Analysis Symposium).

### AI overview

The article explains why graph neural networks underutilize modern GPUs: their irregular, sparse memory access patterns leave the hardware waiting for data. It describes a project that investigated the problem and produced three families of specialized GPU kernels. The resulting paper, "On Efficient Scaling of GNNs via IO-Aware Layer Implementations," was accepted to ICML 2026 as a Spotlight paper.

### Source excerpt

Граф из миллионов вершин не загружает современную GPU на все 100%: видеокарта почти всё время не вычисляет, а ждёт загрузки данных из памяти. Графовые нейросети, или GNN, упираются в это давно: сами операции достаточно простые, но доступ к памяти нерегулярный и разреженный. И чем мощнее GPU, тем заметнее недостаточная её утилизация. Идея выросла из проектного курса в ШАДе. Толчком стало то, что один из самых популярных фреймворков для работы с графами, Deep Graph Library, на момент начала работы не обновлялся уже около года -- это знак того, что в области что-то застряло. Меня зовут Федя Великонивцев, я старший исследователь Yandex Research, руковожу группой, которая занимается эффективными вычислениями на GPU. На том курсе мы с коллегами -- Дарьей Фоминой из команды ML-инфраструктуры Яндекса, Вячеславом Ждановским из команды разработки инференса -- и студентами Даниилом Красильниковым, Алексеем Бойковым и Андреем Долговязовым взялись выяснить, почему графовые нейросети тормозят на современных GPU. Так появился проект, который мы оформили в отдельную статью -- On Efficient Scaling of GNNs via IO-Aware Layer Implementations. Её приняли на ICML-2026 со статусом Spotlight. Для контекста: из 23 918 поданных работ приняли 6 352 (26,6%), а Spotlight достался только 536 работам -- это 2,2% заявок с самыми высокими оценками программного комитета. Дальше расскажу, как мы прошли путь от этого вопроса до трёх семейств специализированных GPU-кернелов -- с парой неожиданных находок по дороге. Читать далее
