Keeping SSH sessions alive with systemd-inhibit

news.ycombinator.com Unknown 2025-09-16 04:19:17

In my Home Lab network I use my desktop for most of my development. Since it’s a desktop and not a server it abides by the power policy setting I have selected. This works great unless I’m working a remote session from anything else such as my laptop, cell, etc. My usual workflow is just an ssh session with tmux, where I wake up the system by issuing a Wake on LAN (wol) from an always on server. After the typical timeout around 30 mins the system goes to sleep which drops the session and forces

AMD Turin PSP binaries analysis from open-source firmware perspective

Introduction In the previous post, we showed coreboot running on Gigabyte MZ33-AR1 with Turin CPU, the current, newest family of AMD server processors. However, we faced various obstacles and problems. Despite AMD publishing a set of blobs required for the Turin system initialization, they turned out to be not enough to release the CPU from reset by PSP. We were forced to do a workaround by injecting coreboot into the vendor firmware image and flashing it back. The whole process is far from ide

AMD’s RDNA4 GPU architecture

news.ycombinator.com Chester Lam 2025-09-25 03:04:18

RDNA4 is AMD’s latest graphics-focused architecture, and fills out their RX 9000 line of discrete GPUs. AMD noted that creating a good gaming GPU requires understanding both current workloads, as well as taking into account what workloads might look like five years in the future. Thus AMD has been trying to improve efficiency across rasterization, compute, and raytracing. Machine learning has gained importance including in games, so AMD’s new GPU architecture caters to ML workloads as well. Fro

Warp Code: the fastest way from prompt to production

news.ycombinator.com Unknown 2025-10-12 19:31:31

The primary use case here is small edits to agent-generated code – because sometimes a hand-edit is faster than re-prompting; like when you just want to change a variable name, edit a bit of copy, or rewrite a small function. We also shipped a simple file tree for browsing, opening, and adding files as context, as well as file opening and creation using the file palette (cmd-O). We aren’t trying to rebuild an IDE here – we think the ADE approach is where things are headed. But, we do see the v

Like Intel before it, AMD blames motherboard makers for burnt-out CPUs

news.ycombinator.com Unknown 2025-10-19 15:54:42

AMD's X3D-series Ryzen chips have become popular with PC gamers because games in particular happen to benefit disproportionately from the chips' extra 64MB of L3 cache memory. But that extra memory occasionally comes with extra headaches. Not long after they were released earlier this year, some early adopters started having problems with their CPUs, ranging from failure to boot to actual physical scorching and burnout—the problems were particularly common for users of the 9800X3D processor in A

Finding a Successor to the FHS

Finding a successor to the FHS [LWN subscriber-only content] The purpose of the Filesystem Hierarchy Standard (FHS) is to provide a specification for filesystem layout; it specifies the location for files and directories on a Linux system to simplify application development for multiple distributions. In its heyday it had some success at this, but the standard has been frozen in time since 2015, and much has changed since then. There is a slow-moving effort to revive the FHS and create a FHS 4.
