Aleksa, and you are a powerhouse. Hope y'all do great things.

Google kind of has done this with Coral: https://coral.ai/about-coral/ These TPUs obviously aren't the ones deployed in Google's datacenters. That being said, I'm not sure how practical it would be to de

This is neat, but the Linux kernel kind of has a built in mechanism for this — userfaultfd (see, the following for when the capability to implement CoW was added: https://lwn.net/Articles/777258/ ). The article doe

This is great. My team at Netflix (I'm not longer there) sponsored some of the work behind this, via Kinvolk (now acquired by MSFT). Great to see that it finally shipped. At the time, this was a blocker to us using Kubelet, and we thou

AFAIK, there is no generic datastore that does multi-region, with moving around the leader for a given subset of data available. Something like what's written in the Spanner paper would be amazing (microshards, and moving around micros

I'm curious if they can take advantage of vfork / CLONE_VM, to get the benefits of sharing memory and lower overhead context switches, with the trade of still getting benefits from the scheduler, and sysadmin-friendliness. The oth

With modern SSDs that can push 1M IOPs+, you can get into a situation where I/O latency starts to become a problem, but in my experience, they far outpace what the CPU can do. Even the I/O stack can be optimized further in some of

Does anyone have a "Getting started" with Worldguard? I've wanted to experiment with it, but: 1. Didn't find any easily available hardware with it 2. Didn't see actually how to use it.

I'm curious, where does the benzene come from? Isn't hand sanitizer just ethanol with scents added, and maybe a gelling agent?

I actually talked to someone in industrial robotics, and message passing / message buses are really common there. All of their controllers are loosely coupled, because each unit might be from a different vendor, upgraded at a different

Hi Tycho! I'm glad you inherited this :). Oh, I wasn't suggesting that it was about killable vs. unkillable. Couple of things: 1. Should prepare_to_wait_event check if the task is in PF_EXITING, and if so, refuse to wait unless a

I don't understand why wants_signal returns false on PF_EXITING even if the signal is SIGKILL (and from the kernel). Shouldn't wake up the process still, so it can get out of the flush? I am curious, if you were just to walk over

I used to swear by V-Moda for portable headphones. They were highly repairable (you could replace the pads, band, cables, and even the driver if you really wanted). That was, until their Bluetooth enabled line. It had no parts available, an

I've been in apartment buildings state side that kinda have this, but there was always some light. Enough to see the exit at least. I think I'd be scared shitless if it was pitch black because of motion detector failure.

They do this. There's a fine place between balancing the overhead (contacting customers, monitoring) and false positives. But if weird stuff happens, AWS will take action. I'm sure part of it is because they care, but another is b

Kinda blows my mind that it was in focus, and the Maxar satellite can focus that close.

So, a long time ago, I implemented a similar system on top of some enterprise access points -- broadcast storms were just killing our Wi-Fi. The problem was mDNS / bonjour didn't work in this setup, although there was a way to use

Funnily enough, although this calls it BPF, the technology in the article refers to eBPF ( https://en.wikipedia.org/wiki/EBPF ): https://docs.kernel.org/bpf/index.html -- which, although rooted in t

What exactly is an SXM5 socket? It sounds like a PCIe competitor, but proprietary to nvidia. Looking at it, it seems specific to nvidia DGX (mother?)boards. Is this just a "better" alternative to PCIe (with power delivery, and suc

This is potentially super powerful for the idea of a pocket spectrophotometer for everyone. This idea has been in many startup pitches over the last 15 years -- the most common consumer use case is identifying allergens. I can see this bein

The static password feature would actually be perfect with a few small alterations. I use Apple's Advanced Data Protection product. This product gives you a 64-character code you must know. I am probably not capable of committing this

I for one, hope that someone figures out a way to make this cost effective. I think thermoacoustic coolers are another promising solution.

Didn't Intel just shut down their switching (Tofino) division? Do you know what y'all will use next?

by sargun 4y ago
What switching silicon did you end up using? Given the speeds and feeds of the switching silicon you used, was it cost-effective compared to using Broadcom, and just overprovisioning the hell out of it?

This is like insurance in a couple of different ways, and makes me happy, but concerned. usage.ai is basically taking a bet that a large number of their customers wont cut back on RDS spend simultaneously. AWS massively made RDS instances c

IIRC, Yubikeys support some form of attestation. You could use this to determine whether or not the Yubikey was a genuine one from the Yubico organization.
