It's unfortunate you're getting downvoted, because this is correct. For anyone that is dubious: Black holes are one of the common ways this gets discussed, because it's such an extreme example, and you can read more about it

I don't have any insider knowledge on this, so your guess is as good as mine on this one :) If you have an account manager or solutions architect, they can probably help you connect with the right people to ask for details, though. (Di

It's not the only option - it can be disabled, the same as on T2 instances. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/t2-unlim... has documentation on disabling it. (Disclosure: I work at AWS,

Farther down the page it talks about T2 Unlimited pricing, which is the same thing here. It does look like it needs to be updated to include details for T3 as well, however. I'll submit some feedback to the documentation team about get

You can find pricing details at https://aws.amazon.com/ec2/pricing/on-demand/ Pricing varies from region to region, on-demand vs. reserved instance, etc. The general answer is they are cheaper than the same s

BPF isn't just a packet filter. It's a JIT VM. This started back in 2011 with https://lwn.net/Articles/437981/ It's since been extended quite a bit from even that, and can be used for a variety of t

I've been with Amazon for coming up on 5 years. I love it here, and have for the entirety of the time I've been here. There are some minor changes I would make if I could wave a magic wand, but I can't imagine any workplace i

Pretty different. WiMax was a legitimate competitor for the 4G standard and was significantly different than 3G and 3.5G networks (Like the HSDPA stuff that some carriers tried to call 4G)

It stops a lot of people from using VS Code and Atom. I already dislike that I need to use other Electron based apps for other reasons, and I'm certainly not going to add to the amount I have to run if I can help it. I think the hope i

I don't - there are plenty of ways to get visual ideas/concepts into the document. You can refer them to the appendix or embed it in. Appendixes are often quite large on complex topics. The big benefit is that meetings start with

Awesome! It'd be pretty sweet if you could send things sampled using Vector over to FlameScope. I know the flamegraphs PMDA is experimental but it's always worked fine for me :) (It'd also be pretty sweet if there was a flesh

Fantastic! I'm particularly excited about the retransmit tracepoints, as troubleshooting some of these issues on systems that can't afford the tcpdump overhead has caused me significant headache in the past.

AMIs that work on c5 instances should work fine on bare metal instances. NVMe and ENA support will be the big two things you need.
