Show HN: Drop – A rootless Linux sandbox with gVisor support

Hacker News ·

I created Drop because I always felt uneasy installing and running third-party programs using my main user account. A single compromised dependency means a full compromise of the system.

Cache Aware Scheduling Fixes Queued For Submission To Linux 7.3, Backporting To 7.2

Phoronix ·

Later this week it looks like the latest round of Cache Aware Scheduling fixes will be merged for enhancing this kernel scheduler functionality for grouping related tasks together on CPU cores that share the same last level cache (LLC). Cache Aware Scheduling can lead to better cache locality and lower latency by avoiding the costs of potential cache bouncing -- that is when bugs don't get in…

Phoronix ·

With the in-development Linux 7.3 kernel showing some nice performance improvements over Linux 7.2 in different areas, Linux 7.2 also having brought some nice gains especially for I/O, and the preceding kernels also having seen some nice performance optimizations this year, I wanted to measure how far the Linux kernel performance has evolved so far in 2026. Today's article is looking at that…

Patches Posted With Aim To Mainline Linux Kernel Support For The Amazon Kindle 4

Phoronix ·

Amazon released the Kindle 4 back in 2011 with a 6-inch E-ink display, 2GB internal storage, and running a modified version of Linux. In the years since the Amazon Kindle 4 has been jail-broken and there are some customized Linux distributions with a patched kernel to run on the Kindle 4. Now in 2026 there are patches on the Linux kernel mailing list looking to mainline support for that fifteen…

Orphaned VMs: Running VMs Uninterrupted While Host Kernel Is Offline For Reboots/Updates

Phoronix ·

Here's some very intriguing work taking place by a Google engineer... With the hyperscalers and other cloud providers pushing for zero-downtime, a set of experimental patches for "Orphaned VMs" allow for the virtual machines to continue to run while the host kernel is offline for security updates or rebooting with the Live Update Orchestrator. The experimental patches and request for feedback…
