They're different approaches to solving the same problem (improved throughput with lower latency and jitter). The major thing they have in common is that they both dedicate hardware to the problem. With respect to AWS, in the historica

Yes, any kernel >= 3.8 includes the relevant offload features. The improvements here primarily come from reduced overhead getting packets out of the VM (not mentioned in the post is that Andromeda 2.1 also eliminates VM exits when packet

Yes, this is enabled for all VMs running on Compute Engine (which includes GKE VMs), however the in-guest iptables &c. bits add non-trivial overhead (I don't have numbers handy, apologies).

At the time Andromeda was originally introduced it took a fairly recent Linux kernel to get support for multi-queue networking and offloads with virtio-net. Today anything even moderately recent has support baked in -- specifically Linux 3.

Wait, what about an escape key for EMACS? My heavy emacs use is the reason I didn't mind getting the touch bar. It's vim users I'd expect to be annoyed...

I had to search to see what you meant by "magenta yellow". My immediate assocation was with the two of them having identical color schemes (although also both being immediately recognizable). I haven't seen the actual radiati

Out of professional curiosity, what are you looking for from ENA? (I'm an engineer on Google Compute Engine with a deep interest in customer networking use stories, particularly heavy utilization customers, even if they're not my

Hey Ronnie -- long time! We should catch up -- drop me a line (personal email is hn username at gmail).

This is fantastic. I'm an American who's been learning Danish casually, and as a native English speaker the pronunciation is... challenging. Even a year or so in, developing an ear for it is still an ongoing process.

It tends to be annoyingly cool when it rains for about six months out of the year. Take today for example -- 50 and raining. It won't kill you if you're otherwise healthy, but being caught out in it without proper attire feels &qu

I would describe the bus drivers in Seattle as assertive. They make their own way if nobody yields.

Yes, but it's tied up in a bunch of other bits like not eating pork and worshipping a particular deity. The secular quip raises the same questions about human motivations without the other baggage.

Wellllll, I can't edit it anymore, but yeah, got that totally wrong (original source was a real estate developer who's involved with a couple of the projects). I suspect he took "about 60% more than any other city" and r

Seattle currently has more than 50% of the cranes nation wide. That said, they're almost universally building apartments (exceptions being Insignia, LUMA, and Nexus, that I know of).

You're begging the question here. Apple's acquisition of PA Semi filled a void. You assume a similar void.

Ah, so, this raises an interesting question: what do people use yes for? One answer (a bad answer) is "generating artificial load". This makes the I/O strategy oddly relevant -- different strategies result in different number

I love Prodesign, but yeah they're not exactly competing on price. Also a big fan of Etnia Barcelona -- they're in a similar price bracket (as far as I know they're independent, but I'll admit to not having researched it

Preemptible VMs exist in part to avoid leaving capacity sitting idle. We hate idle resources. :)

Yes. At least for their high-end server parts, Intel has docs on how many turbo bins you get. AVX can also slow things down all on its own (it reduces the available turbo). A co-worker of mine is (hoping to) speak at KVM forum about this as

Sure, but if really want to avoid trusting trust (and you're of the mind to build your own hardware), FPGAs and µcs offer a lot of room for snooping. Given the GPs suggested use, it seemed trusting trust was not on the table. Certainly

Not for an ASIC without spending a LOT on tooling, and really $10k is awfully optimistic even if you had all of that tooling (I probably should've just said tens of thousands). For <100k, yes, you can absolutely do a small run in th

There are basically two companies in this business, Altera (Intel) and Xilinx. I would not worry about vendor lock-in for now -- there are some quite affordable dev boards (like the Arty ( http://store.digilentinc.com/arty-a7

Certainly! I love what I do, and I love talking about it to anyone who will listen. I find Google's infrastructure is fantastically exciting -- sometimes too exciting, rarely boring. Most of the time I wish I could share more. Always h

If you want to propose punitive legal remedies for the actions of others, yes, you should do your research.

Aren't embedded systems already there? What is a firmware blob if not a monolithic static build artifact? Bazel is perfect for this. I recently taught it how to build boot images for Xilinx FPGAs including a bitstream, first stage boot
