/**
* uffd_wakeup: wake up threads waiting on page UFFD-managed page fault resolution
*
* Wake up threads waiting on any page/pages from the designated range.
* The main use case is when during some period, page faults are resolved
* via UFFD-IO IOCTLs with MODE_DONTWAKE flag set, then after that all waits
* for the whole memory range are satisfied in a single call to uffd_wakeup().
*
* Returns 0 on success, negative value in case of an error
*
* @uffd_fd: UFFD file descriptor
* @addr: base address
* @length: length of the range

reconciliation
Modern cluster managers like Borg, Omega and Kubernetes rely on the state-reconciliation principle to be highly resilient and extensible. In these systems, all cluster-management logic is embedded in a loosely coupled collection of microservices called controllers. Each controller independently observes the current cluster state and issues corrective actions to converge the cluster to a desired st
takeout

inflict
Because that would inflict a costly atomic operation with a full memory barrier on every user/kernel round trip. Also the duty to report quiescent states eventually falls to other CPUs so one must be aware of the exported cost that implies.
tangential
A little tangential, but are these things safe for humans? I have a couple of LD2410 devices and I’d like to use one of them with ESPHome in the bedroom. I did some research and they seem to be very low power and safe, but you know, before sleeping with a radar pointing at us all night long, I’m looking for as much feedback as possible.
polymorphism
sockaddr is a generic descriptor for any kind of socket operation, whereas sockaddr_in is a struct specific to IP-based communication (IIRC, “in” stands for “InterNet”). As far as I know, this is a kind of “polymorphism” : the bind() function pretends to take a struct sockaddr *, but in fact, it will assume that the appropriate type of structure is passed in; i. e. one that corresponds to the type
breeze
Making parsing a breeze
venting
3 years network admin @ the age 33. Feeling depressed and venting
shrewd
Interview with Jason A. Donenfeld WireGuard: Next Generation Secure Kernel Network Tunnel. Cutting edge crypto, shrewd kernel design, and networking meet in a surprisingly simple combination
sentience
I always suspected Emacs would achieve sentience before vim. Maybe I’ll be wrong.
exodus
Maintainers exodus over recent events
revamped
Cilium’s BPF kernel datapath revamped
bastion
We’ve done the basics to lock SSH. But, ideally, SSH would not be accessible from the Internet. You could use firewall rules to restrict access to specific IP addresses. But in my case, I have a dynamic IP, and I don’t want to run a bastion host, so that won’t work for me. Fortunately, WireGuard makes running a VPN easy
bespoke
The genius of ebpf is allowing for pluggable policy in a world where the kernel API is very slow to change and can’t meet everyone’s needs. Whether it’s how the kernel handles packets off the wire, how it controls traffic, scheduling entities, or instrumentation, ebpf lets you provide logic rather than turn a bunch of knobs or use a bespoke syscall that only handles one case. It also moves the pro
vetted
ebpf isn’t really novel beyond the interfaces it provides. They are just kernel modules that have been vetted and are sandboxed. Inserting executable code has been part of the kernel since forever in module form and kprobes.
touted
Aeon is touted as a distribution for users who do not want to hassle with system administration, but its sparse selection of software ensures that some up-front work is required to reach the payoff.
roosting
As I read further, roosting in trees began to sound like the topic of a self-help book for chickens. They gain confidence in their abilities to fly and evade predators.
warranty
The warranty on the base model is only 8 months, and for the higher model only a year. This is not good! Even worse, and likely illegal(!), the warranty has terms that are likely against FTC guidelines, like voiding the warranty if you disassemble the robot. As far as I know, these type of terms are not valid. They also include terms saying your warranty is void if third party service or parts ar
testimonial
I can’t wait to see this as a testimonial on the Proxmox website haha. I agree with the sentiment though.
fluff
I’m going to need a lot more detail before I can believe this. It’s too much fluff to be taken at face value.
blissfully
They are done as program type-specific BPF contexts understood by BPF verifier. So, if you are developing a BPF program with such context, consider yourself lucky, you can blissfully live in a nice illusion of stability.
trove
But as soon as you need to get a glimpse at any raw internal kernel data (e.g., very commonly a struct task_struct which represents a process/thread and contains a treasure trove of process information), you are on your own. It is commonly the case for tracing, monitoring, and profiling applications, which are a huge class of extremely useful BPF programs.
prodded
I doubt it. It’s probably a matter of constantly being prodded by their industry partners (i.e. Red Hat), constantly being shamed by the community, and reducing the amount of maintenance they need to do to keep their driver stack updated and working on new kernels. The meat of the drivers is still proprietary, this just allows them to be loaded without a proprietary kernel module.
ancillary
These macros are used to create and access control messages (also called ancillary data) that are not a part of the socket payload. This control information may include the interface the packet was received on, various rarely used header fields, an extended error description, a set of file descriptors, or UNIX credentials. For instance, control messages can be

placebo
I’m sorry to inform you that this is mostly a placebo effect since Zed internally uses Rust-Analyzer.

plague
HaaS is a plague. Don’t give this company the money that lets them further withhold your ownership of hardware.
harness
马具，在这里引申为框架
In the output, we find a failure in the very first test case float_convs
due to a segmentation fault. Similarly, all harness and libc tests will fail as
well. At this point we have no clue where the actual bug lies, and need to start
ruling out instructions. As such a good starting point is to utilize the debug
options -d in_asm,cpu of QEMU to inspect the Hexagon instructions being run,
alongside the CPU state. We additionally need a working version of the emulator
to compare our buggy CPU state against, running
confiscate
But as Eric Levitz points out, this doesn’t make a lot of sense either — the U.S. is not going to be able to confiscate large amounts of Venezuela’s oil, and flooding the world market with crude will simply depress the margins of America’s own oil producers.
populous
In the 20th century the world’s most populous countries were poor but that was neither the case historically nor will it be true in the 21st century.
agrarian
Just stop trading manufactured products with Asia. Their people are still transitioning from agrarian hardship to urban factory life, and there seems to be a zeal that comes with this transition, a willingness to work hard for what here today would be considered little.
Good for them. But in Europe we had this transition already and we became disillusioned with the lifestyle tradeoffs.
Having our people do nothing productive while all of our life objects are made by others is not sustainable and it is awful for the morale of our peoples. It needs to be stopped.

resonated
I started publishing “TIL” posts a few years ago and everything in this post here resonated 100% with my experience of writing those. The great thing about TILs is that once you form a solid set of habits around them they can be extremely quick to put together: the majority of my TIL posts take between 15 minutes and half an hour to write.
Procrastination
Overcoming Procrastination: Procrastination can be a significant barrier to consistency. Setting a regular schedule, creating a conducive environment, and focusing on the process rather than the outcome can help in overcoming this challenge.

It’s crazy to think there was a fleeting sliver of time during which Midjourney felt like the pinnacle of image generation.

emboldened
Still not sure how I feel about China of all places to control the only alternative AI stack, but I guess it’s better than leaving everything to the US alone. If China ever feels emboldened enough to go for Taiwan and the US descends into complete chaos, the rest of the world running on AI will be at the mercy of authoritarian regimes. At the very least you can be sure noone is in this for the good of the people anymore. This is about who will dominate the world of tomorrow. And China has officially thrown their hat in the ring.
