Oh, do test things in production. Can’t understate the need for good network, especially with the traffic amplification of replication. I was running 2x10GE and had plans to scale up the cluster network to 2x or 3x10GE. My biggest issue was

The issue with Ceph isn't that it's some how deficient. It's amazing. The problem is that it's difficult to engineer correctly and hard to troubleshoot. There is no other software, open source or otherwise that works q

Ceph is extraordinarily complicated to run correctly. The docs aren't great and commercial support is pretty mediocre. It's an amazing piece of software, but takes a great deal of engineering to get right. Most folks won't

Minio is cool. Unfortunately, performance is anyone's guess. It has erasure coding as well. You could deploy on bare VM's with local storage in any cloud provider and have no dependency on network blocked storage. With k8s 1.10

Ceph has some weird failure modes, though. Your radius of failure absolutely includes the entire cluster, regardless of how resilient its been made. Sure, you're insulated from hardware failures, but not from bugs in the underlying sy

It's very likely that they have 1.1.1.1 in their "bogons" list and have for a very long time. Bogons are a list of prefixes that most ISPs blackhole as there is usually never any legitimate traffic bound for those destination

Calico. Also, my customers don't have strong requirements for network isolation. I'd be more concerned about compliance in areas like finance or healthcare.

Clusters come up faster. They're easier to upgrade. Don't have to delete clusters to change them (just provision a new node pool). Persistent storage is less weird. No RBAC. Weirdness around kube-system namespace. I.e. if I c

Team is six people. First started using k8s in prod in May 2017 for monitoring.

My company is running it in production. We started with the monitoring stack and then our application, which is a SaaS product. The product itself is a stack deployed on a per customer basis. With rough configuration management using che

I'm using both AKS and GKE in Google and I have to say that GKE is way, way nicer to work with.

You could run whatever you like in an alpine container on ResinOS

by halbritt 9y ago
ResinOS does all that and more. It's container-based. Works super-well on a Pi3.

I've been wanting to attempt to make a coaxial movement, roughly that size as well. As there's no chance I could make one that would fit in a watch. I've also pulled a few Unitas (pre-ETA acquisition) movements out of stopwa

Japan produced an IPSC champion some years back. In Japan, he trained exclusively with an airsoft pistol and only ever fired a gun when he came to the US to compete.

My team created a helm chart for this. EFK soup to nuts with x-pack. I'll see if we can't publish it.

Late reply, I know. The folks pulling down 160 amps are racing and don't care about exploding batteries. In fact, they expect to.

I have. For whatever reason, I had difficulty with it.

The first time I visited Seattle was the middle of July. The weather was warm and sunny. I recall going swimming in Lake Washington. Everyone was really, really happy and joyful, to the extent that I wondered if I had been lied to all my

pandas.read_csv is kind of abysmally slow, unfortunately. There are a couple of alternatives, but nothing has really taken hold. Dask exists, but not everyone can run a distributed system to read a multi-gigabyte csv.

To your point 1: This is the reason that AsyncIO exists in Python 3.6 and IIRC Facebook is pushing really, really hard to adopt it.

Wire runs are so short and peak current is so brief that it effectively doesn't matter. Most folks run 14AWG between the battery and the power distribution board. PDBs are generally made with 2oz copper and wide traces to accommodate

Racing drones typically fly at extreme tilt angles such that the wake of the front props isn't interacting very much with the wake of the rear props. That said, I have seen that configuration on a frame.

Max output of a motor is constrained by weight, or more specifically, its ability to dissipate heat. Racing quads generally use 30-40 gram motors. The top racing motors these days produce 1.6kg of thrust at max output and consume 40 amps

No apologies necessary. I wasn't vehemently disagreeing with the parent so much as saying that the cost-benefit analysis is worthwhile. I do some IIoT stuff, so I have a little experience here. Many of the lower cost PLCs and industr

There aren't really "networking events". It's a community of like-minded people that aren't particularly eager to add more people to the community that aren't also like-minded. That aside, they can be fairly i
