This just spurred me to check recent sales prices: https://auctions.ipv4.global/prior-sales Check the charts for price since 2020. It looks like IPv4-block prices almost tripled 2020-2021. Then seem to have been in gradual

I’ve just been reading some of Vernor Vinge’s books and they’ve certainly hit different the second time around (A Deepness in the Sky, A Fire Upon the Deep). I think it really is mostly that I’ve changed. It’s been a slow change that has be

They’re like cast iron pans. The flavour builds over time as long as you don’t wash them too thoroughly.

I’m in the market for new monitors (or maybe only one in this case!) A question if you don’t mind - Do you find 4K resolution to be sufficient on a 40” screen? Also just eager to hear any others reasons why you like it

In addition to the other replies, I also recall hearing some time ago that the AC EM field interacted with wildlife in surprising ways (causing sharks to attack the cable, IIRC). It could be an urban legend at this point though.

Our experience with Hetzner /Cloud/ is similarly shaky. But Hetzner dedicated servers all altogether a different story. We (lithus.eu) deal with their custom solutions team regularly and often provision private networks in the 10-

Interesting. This is something I've yet to encounter, and we use Hetzner a lot for our clients (dedicated servers though, not cloud, so maybe that makes a difference).

Oh wow, this is exactly what we're doing. We've been doing this for a while, but since last year we've gone all-in on it. See: https://lithus.eu We saw that companies were hesitant to deploy on bare metal because

> UDP message delivery order is not guaranteed My thinking was that ordering would be pretty unaffected when there is only a single hop. But yeah, we would have needed to test that under load.

I had a developer colleague a while back who was toying with an idea that would require emitting and consuming a _lot_ of messages. I think it was somewhere on the order of 10k-100k/second. He was looking at some pretty expensive solut

So this is something I/we have a bit of experience in [1]. Firstly, I'd test what level of on-prem they are really asking for, because there are various shades of this: - servers actually in their office - their own servers in a d

This is certainly interesting, and is something I often wonder about. In our case we mostly run Kubernetes clusters on EX130 servers (Xeon, 24c, 256GB). In this situation there are a lot of processes running, for which increased cores-count

There are some excellent comments here, so I'll just add my particular flavour. I think using Kubernetes effectively in 2025 is more about what you _don't_ use than what you _do_ use. As an early stage startup you can get a long w

Very cool and fun! The first thing did when I opened it was to point my phone at the floor though, trying to find Australia. Took me a moment to realise it wasn’t that kind of pointer!

I love the sound of this, but the readme could really benefit from the screenshots. That way I can get an idea of what it looks like without having to actually start it running.

To answer from a Kubernetes perspective: Both OpenEBS Mayastor and LocalZFS now support disk encryption.

This is exactly what we [1] do! We migrate clients out of AWS and into Hetzner bare-metal k8s clusters, and then we also become the client's DevOps team (typically for a lot less than Amazon charges) I will say that there is a fair bit

We're setting up a data-heavy client at the moment who has a similar need. We're working with Hetzner's custom solutions team to provision a multi-AZ setup, with 25G networking and 100G AZ interconnects. Link in bio if you wa

by adamcharnock 1y ago
This certainly looks like a pleasingly straight-forward way to spin up k8s. I do notice that this deploys onto their cloud offering, which we've ( https://lithus.eu ) found to be a little shaky in a few places. We deploy clie

I left a comment fairly related to this a while back: https://news.ycombinator.com/item?id=43465403 But there _is_ also an attitude difference. In terms of willingness to take risks and innovate, the USA does do very well f

This may be blindingly obvious, but I’m going to say it anyway: If Amazon was willing to actually give up control of AWS EU, then this kind of announcement would be entirely surplus to requirements. But they will (obviously and rationally)

I think this is a really interesting point. I have a few thoughts as a read it (as a bit of a grey-beard). Things are moving fast at the moment, but I think it feels even faster because of how slowly things have been moving for the last dec

I think this is more akin to shutting down an AZ, rather than a region, which certainly does happen. Except AZ lettering is randomised per AWS account, so your 'us-east1-a' isn't my 'us-east1-a'. Which means AWS can

An interesting idea! I suspect a major speed up would come from the fact that the column is staying the same size. So (I assume) far fewer bytes would need to be moved around.

Indeed, I think I came to the incorrect conclusion! Just signed up for a subscription after getting through quite a lot of API funds!
