I'd say that medicine has been a net benefit to bettering the lives of those who have access to it. I'm biased, though - "drugs" have kept me alive and able for the last 30 years.

The gray market for peptides is pretty fascinating. I've spent the last month exploring it and interacting with some of the Chinese entrepreneurs involved, as well as the informal regulatory functions provided by self-organizing groups

I'm pretty new to Rust so forgive me if I'm mistaken, but it seems to me that this crate doesn't require the use of tokio.

Swapping in a multi-vendor world also implies standardization. It’s too early in this technology to standardize - that would stifle progress. Swap stations would also be far more expensive to build and manage inventory for, and would carry

If CSV were being used just to exchange data with Excel, we probably wouldn't be using CSV. Many systems neither need nor know that ="01" should be treated as the string "01". If Excel were the only intended consume

That's a good point. But then you're not benchmarking C++ as a distinct language. So what would sufficiently distinguish a C++ program from a C program? Let's assume it's not just minor incompatibilities introduced to pr

Ha! I picked up the original project (dosemu1) from an abandoned skeleton created by Matthias Lautner. I was a larval programmer and Linux was very much in its infancy. I really wanted to run Civilization on my one computer without keepin

Can you expand on this: "AWS healthchecks each kubernetes node, but not your pods themselves". Are you talking about a keepalive connection to an unhealthy pod which is reused for multiple requests? So the failure modes are, if I

Fewer features and fewer lines of code, and those LOC are written in Go, which is the language in which CockroachDB is written and which, presumably, for which their team and tooling are best optimized. It's a reasonable thesis.

I wrote a little fork+spinloop program w/100 subprocesses and deployed it with a low (100m) CPU request and no limit. It's certainly driving CPU usage to nearly all 8 of the 8 cores on the machine, but the other processes sharing

That may be more likely with limits, but it doesn’t require a limit. I’ve had lots of fun with that in Elasticsearch pods with no limit. And then you get to enjoy a nice cascading failure.

by rsanders 6y ago
I should have said that it seems like the wrong fix to the problem. But I have since learned that limits can cause excessive throttling. And of course you may want your pods to be burstable, but that would just be a question of setting ap

Can you explain how having a CPU limit set (at any level) has a negative effect on latency? That's an important factor to understand. The arguments for allowing containers to burst makes plenty of sense to me. I do it on most of my ser

by rsanders 6y ago
A container with a request but without a limit should be scheduled as Burstable, and it should only receive allocations in excess of its request when all other containers have had their demand <= request satisfied. A container without ei

Excluding kernel bugs, CPU limits just provide an upper bound on burst capacity. That controls oversubscription of CPU on a node. As with any other kind of oversubscription of a resource based on variable demand, there is a tradeoff. Allowi

Removing CPU limits seems like a bad idea now that there's a kernel fix. But putting that aside... I don't understand why pods without CPU limits would cause unresponsive kubelets. For a long time now Kubernetes has allocated a sl

by rsanders 6y ago
This advice is confusing. CPU is a "compressible" resource -- pods don't get killed for (trying to) exceed it. Pods don't get evicted from nodes based on CPU starvation, so autoscaling your node count won't help if

The support for multi-arch docker images is getting there, but there's not much of an ecosystem. Between Raspberry Pi, ARM instances on AWS, and ARM-based Macs, it ought to get to critical mass before too long.

Retrying transactions is something every app ought to handle, but it's rare enough that most codebases I've seen just punt on it.

My last company used Terraform to manage Kubernetes. The main issue is that the TF Kubernetes provider supports a limited subset of K8S object types, and of fields within those K8S objects. For example: TF didn't even support Deploymen

I believe that if you have a Parquet file meeting certain criteria, it's directly parallelizable as multiple Spark partitions without any shuffling. The splits would occur at Parquet row group boundaries, I believe. See https:/&#

The situation isn't terribly different for private health insurance. You're still spending out of a shared pool of dollars, and you don't have complete freedom in how you choose to do so.

My company has about half of our services inside Kubernetes, and multiple K8s clusters, so this is a dream come true. We'd already been eyeing Connect as a much simpler service mesh we could use both inside and outside K8S. It does see

The JVM tax on footprint isn't terrible when there is one instance per host providing the service mesh for all processes on that host. In a containerized deployment model, however, each process may have a "sidecar" process pr
