How I fixed Out of Memory (OOM) errors when building a 500+ post Astro blog on Vercel, reducing build time to 2 minutes 19 seconds

This guide walks through building a full NVIDIA GPU compute node on Ubuntu 20.04/22.04, targeting HGX A800 and Tesla data center GPUs. It covers disabling Nouveau, installing the NVIDIA driver and CUDA, configuring Infiniband with MLNX OFED, enabling key kernel modules, building OpenMPI, setting up NCCL and FabricManager, and validating with single-node and multi-node NCCL+MPI benchmarks.

Twikoo comment notifications keep failing with 401 errors? This post traces the root cause to Vercel’s default authentication protection, walking through how logs reveal the issue and how to fix it: disable project-level auth protection so Twikoo’s internal POST_SUBMIT requests can pass through and restore Telegram and other notification channels.

This article walks through building a unified, secure, and auditable access gateway using Teleport. It explains core concepts and architecture, covers SSH/Kubernetes/DB/application/desktop access, zero-trust and auditing features, then provides a hands-on Docker-based deployment guide and shows how to enroll additional servers into the Teleport cluster.

This guide walks through installing NVIDIA GPU drivers with CUDA support on Ubuntu 22.04, including prerequisite packages, Vulkan libraries, CUDA Toolkit, and Clang. It also covers setting up Docker and NVIDIA GPU support for containers via nvidia-docker2, and verifying that the GPU, CUDA environment, and GPU-enabled Docker runtime are working correctly.

Amid rising hardware and cloud costs in late 2025, LET’s floor price has climbed to $10 and memory vendors are hiking contract prices sharply. This post records my Black Friday 2025 hauls: Netcup RS2000, HostBrr flash‑sale storage VPS, Hetzner AX162‑S dedicated server, plus the S.EE short‑link & analytics platform, with configs, YABS benchmarks and buying notes for seeding/backup use cases.

Hands-on benchmark of GorillaServers’ dual EPYC 7502 clearance server from WebNX: 128 threads, 512GB RAM, 2×1.92TB NVMe and 1Gbps network in LAX. Covers CPU and network performance, storage health, Geekbench/PassMark/UnixBench results, WebNX upstream advantages, Tenantos automation, overall value and potential drawbacks for high-bandwidth workloads on a budget.

Black Friday deals are here. This in-depth HostBrr Threadripper 9995WX VPS Benchmark compares it head‑to‑head with the 9950X and EPYC 9655, analyzing raw performance, overselling risks, and value for money. It also breaks down package pricing, StorageBox and block storage promotions, and offers practical buying advice for different workloads and budgets.

Hands-on Black Friday benchmark of Hetzner AX162-S: EPYC 9454P with 48 cores / 96 threads, DDR5 ECC and Gen4 NVMe. YABS sequential throughput over 5 GB/s, Geekbench 6 multi-core around 19,000. At €199/month, this DuFu-series dedicated server still offers outstanding price‑performance despite Hetzner’s slower recent updates.
