[$] Improving the merging of anonymous VMAs
The virtual memory area (VMA), represented by struct\
vm_area_struct, is one of the core abstractions of the kernel’s
memory-management subsystem; a VMA represents a portion of a process’s
address space with the same characteristics. A memory-mapped file will be
represented by (at least) one VMA, as will the process’s stack or a region
of anonymous memory. Efficiently managing VMAs and the logic around them

[$] A process for handling Rust code in the core kernel
The 2024 Linux Storage, Filesystem, Memory-Management, and BPF Summit
included a tense session on the use of Rust
code in the kernel’s filesystem layer. The Rust topic returned in 2025 in
a session run by Andreas Hindborg, with a scope that also covered the
storage and memory-management layers. A lot of progress has been made, and
the discussion was less adversarial this year, but there are still process
issues that need to be worked out. ⌘ Read more

[$] The state of the page in 2025
The folio transition is one of the most
fundamental kernel changes ever made; it can be thought of as being similar
to replacing the foundation of a building while it remains open for
business. So it is not surprising that, for some years, the annual Linux

session on the state of this transition. The 2025 Summit was no exception,

↳ In-reply-to » my biggest fear of starting to work with servers professionally is realizing that no one uses servers anymore and having to do some cloud bullshit instead

@kat@yarn.girlonthemoon.xyz Using full-blown Cloud services is good for old people like me who don’t want to do on-call duty when a disk fails. 😂 I like sleep! 😂

Jokes aside, I like IaaS as a middle ground. There are IaaS hosters who allow you to spin up VMs as you wish and connect them in a network as you wish. You get direct access to all those Linux boxes and to a layer 2 network, so you can do all the fun networking stuff like BGP, VRRP, IPSec/Wireguard, whatever. And you never have to worry about failing disks, server racks getting full, cable management, all that. 😅

I’m confident that we will always need people who do bare-bones or “low-level” stuff instead of just click some Cloud service. I guess that smaller companies don’t use Cloud services very often (because it’s way too expensive for them).

wahhh i wanna work towards my dream of offering pay as you can web hosting (static & dynamic) but i don’t know how!!!!! i keep drifting towards hosting panels but i don’t exactly have fresh linux servers for those nor do i like the level of access they require. so i’m like ok i can do the static site part with SFTP chroot jails and a front-end like filebrowser or something…. but then what about the dynamic sites!!!!!!! UGH

granted i doubt i’d get much interest in dynamic sites but i’d like to do this old school where i can offer people isolated mySQL databases or something for some project (i’m thinking PHP based fanlistings), which means i could do it the old school way of… people ask me to run it and i do it for them. but i kind of want to let people have access to be able to do it themselves just short of giving them SSH access which isn’t happening

Hacer software código opensource es desafiante y paulatinamente desgasta a su autor. Todo comienza con pasión y entusiasmo, por supuesto. Si logras repercusión, te enfrentas a una carrera de fondo que muchos terminan abandonando por las demandas constantes de usuarios que, a menudo, no valoran el trabajo ni contribuyen de manera significativa. Por mencionar un caso reciente: Hector Martin. Líder del proyecto Asahi Linux, quien dedicó años a adaptar Linux para los procesadores Apple Silicon, un logro técnico impresionante. Sin embargo, terminó renunciando debido a la presión de usuarios que exigían soporte y mejoras como si fueran clientes pagos.

La mayoría de los mantenedores no reciben ningún soporte económico. Solo unos pocos proyectos logran sostenibilidad financiera a través de patrocinios, mientras que la mayoría de los desarrolladores terminan con un segundo empleo no remunerado.

Sin un cambio en la forma en que se valora y apoya los proyectos Opensource, y no solo hablo de las grandes empresas multimillonarias. Sería una perdida para todos si acabaremos con un ecosistema de software archivado y abandonado.

Ahora te paso la pelota a ti, ¿cuando fue la última vez que apoyaste a un mantenedor de software opensource?
