UCall
Web Serving and Remote Procedure Calls at 50x lower latency and 70x higher bandwidth than FastAPI, implementing JSON-RPC & REST over io_uring ☎️
Yes, I was planning a similar experiment with UCall (https://github.com/unum-cloud/ucall), leveraging the NUMA functionality introduced in v2 of Fork Union. I don’t currently have the right hardware to test it properly, but it would be very interesting to measure how pinning behaves on machines with multiple NUMA nodes, NICs, and a balanced PCIe topology.

Project mention: How to get virtual display outputs on Linux without using a dummy plug | dev.to | 2026-01-09
In Using the EVDI driver - Extreme Multihead - ArchWiki, it is suggested that this driver can be (ab)used to create virtual outputs without a DisplayLink dock. You will lose out on GPU acceleration that way, but the result is still usable for general tasks. The ArchWiki links to nvidia - Unable to add a VIRTUAL display to Xorg - Unix & Linux Stack Exchange, but the Etam Software - Virtual screen guide is clearer and lets you know that the current Xorg session will freeze during initial configuration. Although I've had luck deploying this solution for a long time on my machine, an update to EVDI suddenly now results in an unusable black screen, even tho this was supposedly patched in Monitor blank but detected as connected · Issue #523 · DisplayLink/evdi, I was never able to get it working again just using EVDI.

Hi, this is my analysis of a bug I found on the simplefs project. Here's the project link. This was my first time finding a bug and trying to figure out the cause. Although the core root cause was not found by me, I did play some role in pinpointing the cause. I hope anyone interested in filesystems, the linux kernel, and low level computing in general could find some use from this post.

kasld
KASLD maps the Linux kernel virtual and physical memory layout as an unprivileged local user to defeat Kernel Address Space Layout Randomization (KASLR).
Randomizing the kernel location is of marginal utility at best. There are so many info leaks that KASLR ends up being only a small speed bump on the way to exploitation.
Here's a cool project that inventories all your KASLR info leaks: https://github.com/bcoles/kasld
