Eh, at least one of those -- the "crashing the node" with messages argument is weak-ish, you can setup:

  erlang:process_flag(message_queue_data, on_heap),
  erlang:set_process_info_limit(memory, 1024000).

Isn’t the highly connected nature of the model layers problematic to build into physical layer?

I find it a little funny how much the government spends on these dead end investigations. We never will know precisely how much is wasted.

What ethnicity are you? I went through an airport -- and nobody else got screened except me. What was special about me? I was the only non-white person in the airport. Upon complaining, this was the response:

> Random selection by our screening technology prevents terrorists from attempting to defeat the security system by learning how it operates. Leaving out any one group, such as senior citizens, persons with disabilities, or children, would remove the random element from the system and undermine security. We simply cannot assume that all terrorists will fit a particular profile.

Andy Pavlo absolutely seems like the kind of guy that I would want to get a drink with.

So, you’re essentially washing the soil in DMSO, and DDT is more soluble in DMSO? — curious, what does it take to wash all that soil?

I have wondered why the likes of McKinsey, KPMG, and PWC do not put up candidates (don't even sponsor them, just say you're electing _well known consultancy_).

New comment by sargun in "Kernel: Introduce Multikernel Architecture Support"

sargun — Sat, 20 Sep 2025 03:19:42 +0000

The author (Cong Wang) is building all sorts of neat stuff. Recently, they built kernelscript: https://github.com/multikernel/kernelscript -- another DSL for BPF that's much more powerful than the C alternatives, without the complexity of C BPF. Previously, they were at Bytedance, so there's a lot of hope that they understand the complexities of "production".

New comment by sargun in "Booting 5000 Erlangs on Ampere One 192-core"

sargun — Sun, 10 Aug 2025 16:20:08 +0000

I really like the manycores approach, but we haven’t seen it come to fruition — at least not on general purpose machines. I think a machine that exposes each subset of cores as a NUMA node and doesn’t try to flatten memory across the entire set of cores might be a much more workable approach. Otherwise the interconnect becomes the scaling limit quickly (all cores being able to access all memory at speed).

Erlang, at least the programming model, lends itself well to this, where each process has a local heap. If that can stay resident to a subsection of the CPU, that might lend itself better to a reasonably priced many core architecture.

I think the most interesting thing about this is the origin of the project - multikernel. It seems like someone is building Solaris zones for Linux.

New comment by sargun in "Why I wrote the BEAM book"

sargun — Wed, 04 Jun 2025 16:14:10 +0000

Investment gap is what I'd say too. While Rust, Go, Python, etc... have had massive backers that have managed to invest a ton more into things like static analysis, type checking, and developer ergonomics, the Erlang ecosystem hasn't necessarily had the same love, and instead the major users have typically chosen to pivot, or build something outside of the BEAM.

What's the biggest barrier to creating a lot of antimatter?

New comment by sargun in "WASM will replace containers"

sargun — Wed, 12 Feb 2025 04:29:06 +0000

No it wont. It's incredibly hard to build out a fully useful version of the Linux APIs, as shown to us by Cygwin, and WSL. Even if you built out a similar set of APIs, Linux itself offers a ridiculous set of interaction points where applications can tie together (for example, I can use inotifywatch to copy files out of my container as they're written). I feel like what you'll end up with is something like gvisor running on top of WASM. In which case, what did we gain from VMs at all?

1. AWS and their account managers are relatively frugal compared to other enterprise sales teams. As far as I can tell, this is a good thing.

2. More

3. AWS has this idea of “customer obsession.” They will spend an absurd amount of time trying to understand your business and make sense of it.

What if I told you that a modern MBP has more IOPs (and faster individual cores) than servers that many large companies use?

sargun — Thu, 09 Jan 2025 03:06:00 +0000

Wasn't there a paper from Heidi Howard that stated you it's not actually f failures in 2f+1 nodes, but you can actually make the number of nodes that can fail a lot higher, if you have some nodes that have to take part in the quorum (or the prior proposal)? This feels roughly similar?

I wish the article actually talked about the interesting nitro enclave specific features more. A lot of it just talks about the basic hardening of a Linux VM and writing secure applications.
