Your confusing concurrency with parallelism. Async allows one core to switch between many threads of execution that can do work and not stop one thread of execution because it need…

Writing code is cheap. Owning code is getting more and more expensive. SWEs sacrificed their jobs so that SREs could have unlimited job security.

If the human race is wiped out by global warming I'm not so sure I would agree with this statement. Technology rarely fails to have downsides that are only discovered in hindsight …

I would have said the same thing a year or two ago, but AI is capable of doing deep dives. It can selectively clone and read dependencies outside of its data set. It can use tool c…

Staff engineer (also at FAANG), so yes, I have at least comparable experience. I'm not trying to summarize every level of SWE in a few sentences. The point is that AI's infallibili…

Same situation as when an engineer can't figure something out, they translate the problem into human terms for a product person, and the product person makes a high level decision …

The question isn't whether businesses will have 0 human element to them, the question is does AI offer a big enough gap that technical skills are still required such that technical…

The answer is the AI. It's already handling complex issues and debugging solely by gathering its own context, doing major refactors successfully, and doing feature design work. The…

After working with the latest models I think these "it's just another tool" or "another layer of abstraction" or "I'm just building at a different level" kind of arguments are wish…

Ah, I thought this was adding refinement types to Rust based on Liquid Haskell. Disappointed.

I switched to mutt, started getting through my email in half the time in took me using a GUI, and never looked back. Being able to write simple expressions to filter email, mass de…

This is an essential use case for XDP - this is how FB's firewall works, and above that their LB uses the same technology. The beauty of XDP is that it's all eBPF. Completely custo…

XDP is built into the kernel. DPDK is a huge framework that invasively bypasses the kernel and has to remain compatible as an external project.

In the case of XDP, the reason it's so much faster is that it requires 0 allocations in the most common case. The DMA buffers are recycled in a page pool that's already allocated a…

DPDK is a framework with multiple backends, on the receive side it can use XDP to intercept packets. You can't compare the efficiency of the frameworks without talking about the sp…

I think the title is a little disingenuous and the idea of using a redirect is certainly not novel. The solution for XDP egress should be able to handle all host egress including s…

I sincerely wonder how some people go around having 0 emotional attachment to any of their hobbies or passions - or maybe you're just extremely unfortunate and live your life compl…

> there are teams already that absolutely do not hand-code anything anymore The only instances I've seen so far are from developers who are really, really bad at coding, but, under…

> Coding is the means to an end, not the end itself. For the early MIT hackers, and for many of us still today, it absolutely is. It's also not about the input mechanisms, which ha…

No one uses dtrace anymore. bpftrace is integrated into the kernel and can extract btf type information embedded into the kernel binary.

It sounds like you've only ever written code without dealing with it in production. You can't always plug your code into an IDE when your debugging someone else's JVM app on a remo…

Because if I'm debugging a critical issues and wading through multiple layers of processes and system interactions, I don't want to have to learn a bespoke toolkit and debugging sy…

That's a really narrow view of the world, and I think another Javaism to think that Java is the entire world. Today's multi-service deployments run tens if not hundreds of auxiliar…
