Posts about the Linux kernel, distributions, command-line tooling, and the day-to-day care and feeding of Linux machines — from desktops to homelab servers.
A database can get measurably faster after adding RAM, even without touching its own memory settings. The extra memory doesn’t go to the database — it goes to the Linux page cache, and that changes how many reads actually hit disk.
On Linux, a network interface is not necessarily a physical network card — it’s a kernel networking object. Some represent real hardware; others connect containers, attach VMs, create tunnels, carry VLANs, build overlays, or separate routing domains entirely.
QUIC did not choose UDP simply because “UDP is faster.” The bigger reason was architectural — TCP had become difficult to evolve because its transport logic lives deep inside operating-system kernels and decades of middleboxes had learned to expect TCP to behave in very specific ways.
Every process thinks it owns all of RAM. It doesn’t. Your process has never touched real memory at all and why the CPU lies to your code on every single memory access.
