Kubernetes 1.35 GA: an operations-side balance sheet

Kubernetes 1.35 GA consolidates three releases of work: native sidecars with full lifecycle management, generalised DRA for FPGAs and NPUs, and a scheduler that cuts resource waste by 15-25% in heterogeneous clusters. An operations-side balance sheet: what to enable now, what to watch before migrating, and what path to follow from 1.30.

NVIDIA alternatives in 2026: where the market is heading

NVIDIA still dominates frontier-model training in 2026, but inference tells a different story. AMD MI300X/MI325X with mature ROCm, Intel Gaudi 3, Google TPU v6, and AWS Trainium/Inferentia deliver 20 to 50% lower cost per token without sacrificing quality. Here is when to choose each option.

Next-generation NPUs: the hardware moving AI in 2026

NPUs stopped being an accessory and became the component that defines real performance in laptops, phones, and small servers. A practical look at the hardware that rules 2026, which workloads pay off, and where the traditional GPU still wins.

XR, AR and VR in 2026: the honest state after the cycle

After the 2023-2024 hype cycle led by Apple Vision Pro, the 2025 valley of disillusionment, and the quiet but real consolidation of Meta Quest 3S and the WebXR stack, it is time to assess honestly where extended reality stands. What works, what has died, what is still alive.

WASI preview 3: adoption and real cases

WASI preview 3 llegó como estándar estable a finales de 2025 y ha tenido unos meses para demostrar si realmente desbloquea los casos que preview 2 se quedaba cortos. Recorrido honesto por adopciones reales, bibliotecas maduras y patrones que empiezan a funcionar en producción.

gVisor: sandboxing for multi-tenant containers

gVisor interpone un kernel en espacio de usuario entre el contenedor y el anfitrión. Después de años en producción en Google y adopción creciente en plataformas serverless, merece una lectura honesta sobre cuándo compensa frente a microVMs y runtimes clásicos.

Microsoft Garnet: a high-performance cache alternative

Garnet es el servidor de caché abierto por Microsoft Research que habla el protocolo de Redis pero está escrito en .NET 8 con un núcleo de almacenamiento orientado a hardware moderno. Tras casi dos años en público, muestra números interesantes y una arquitectura que merece mirarse con calma, aunque el ecosistema Redis siga siendo más maduro.

OSV-Scanner: vulnerabilities with a source of truth

OSV-Scanner se ha convertido en una referencia silenciosa para escanear dependencias open source. Su valor no está en el escaneo en sí, que muchas herramientas ofrecen, sino en su conexión directa con OSV.dev como fuente de verdad. Un análisis de por qué esto importa más de lo que parece.

Unikraft and unikernels: the promise that returns

Unikernels were promised as the future of cloud deployment back in 2015, then faded into obscurity soon after. Ten years later, Unikraft has reached a stable release and reads like a more mature, more useful take on that same idea. A review of what has changed.

Carbon-aware computing: now the default behavior

Four years ago it was an academic curiosity. Today, scheduling workloads by grid carbon intensity is a built-in option in Kubernetes, in several cloud provider services, and in CI tooling. We look at what genuinely changed and what is still more promise than practice.

NVIDIA Blackwell GPUs: what changes for training

Los primeros racks GB200 NVL72 llevan meses en manos de los hiperescalares y ya empiezan a verse mediciones públicas. La generación Blackwell no es una mejora incremental sobre Hopper, sino un cambio en la forma de entrenar modelos grandes. Repasamos qué cambia y qué no.

Kubernetes 1.34: a summary for teams with little time

Kubernetes 1.34 ships with Dynamic Resource Allocation (DRA) graduating to stable, scheduler improvements, and CEL-based mutating admission policies that replace webhooks. A practical rundown of what is safe to upgrade now, what can wait, and what actually changes for teams running production clusters.

Private 5G networks: enterprise deployments in 2025

After years of pilots, private 5G is starting to show up in plants, ports, and warehouses with cases that actually work. What changed in 2025, which deployments make sense, and where WiFi 6E or a wired network still win the comparison.

Continuous profiling with eBPF in production

Continuous profiling with eBPF samples every process's execution stack every few milliseconds without touching the code, then stores the history so you can compare last week's performance with today's. The cost measured in production runs between 1% and 3% of CPU, and it pays off most in databases, API gateways and high-concurrency services.

VEX: filtering vulnerability noise with context

Después de años acumulando SBOMs, el cuello de botella es filtrar qué CVEs afectan de verdad. VEX aparece como la pieza que convierte el ruido en señal, y en 2025 empieza a tener adopción real en pipelines de supply chain.
