Cider (and p4/g4c etc) was amazing when I left back in 2020, I loved it so much, and truly miss it. I rejoined Google last year, and they'd replaced it with a VSCode clone that truly was just a glorified text editor and most were

That's what Locally Recoverable Codes (including Pyramid Codes) are designed to address: you can repair a missing block using only a subset of the blocks, which you can make sure are placed in just one zone, eliminating the cross-az ba

GCS / Azure can survive a total AZ failure too, think of 3 x Replicas as RAID-1, whereas Erasure Coding is more like RAID-6. Only it's actually more resilient: Let's say you have 10 data blocks, and you have 4 parity blocks.

Is it 3x redundancy forever? I always just kinda assumed it was RS encoded after a while, so only 30-50% larger than a single copy. Plus, almost all object storage is written to / read from hard disks, not to SSDs. Unless they're

Insanely high S3 storage charges too. $23/TB/month? Even with the insane HDD pricing that we see today, that's paying off a drive in 1 month (at retail) that will last for 50-100 months. Sure, there's probably some encod

Commits or pushes? Commits aren't really a worthwhile source of measurement in terms of load.

Someone came up with a good theory a while ago that I'm inclined to believe: The social media companies (esp. Meta as I understand it) were looking at huge fines for showing adult content to under-18s, so they lobbied hard to ensure th

That's the point, though. An SSH key gives authentication, not authorization. Generally a certificate is a key signed by some other mutually trusted authority, which SSH explicitly tried to avoid.

I've never quite understood why there couldn't be a standardised "reverse" HTTP connection, from server to load balancer, over which connections are balanced. Standardised so that some kind of health signalling could be

They're 47 inches long. Amazon (UK) has 48 inch long zip ties for $14.45 (pack of 12), 60 inch long for $18. Not quite as thick or wide, sure... But that's not what was in the headline :P

Interesting... It's been ~15 years since I last used BitTorrent personally, and I had asked a friend before replying and they swore that all their traffic was TCP -- though perhaps that may be due to CGNAT or something similar causing

... What? You realise BitTorrent runs over TCP/IP right?

by dotwaffle 1y ago
My example was to show locally what happens -- the ISP does not have control over how many connections you make. I'm saying that if you have X TCP connections for HTTP and 100X TCP connections for BitTorrent, the HTTP connections will

by dotwaffle 1y ago
Exactly. As it happens, this is an area I'm working on right now -- instead of using a star topology (direct), or a mesh (BitTorrent), or a tree (explicitly configured CDN), to use an optimistic DAG. We'll see if it gets any tract

If you download 2 separate files over HTTP, you'd expect each to get roughly 1/2 of the available bandwidth at the bottleneck. With 1 HTTP connection downloading a file and 100 BitTorrent connections trying to download a file, all

> bittorrent will make best use of what bandwidth is available. At the expense of other traffic. Do this experiment: find something large-ish to download over HTTP, perhaps an ISO or similar from Debian or FreeBSD. See what the speed is

by dotwaffle 1y ago
From a network point of view, BitTorrent is horrendous. It has no way of knowing network topology which frequently means traffic flows from eyeball network to eyeball network for which there is no "cheap" path available (potential

The "go x.yy" line in go.mod is supposed to be that MSGV, but `go mod init` will default it to the current version on creation. While you could have tooling like `cargo-msrv` to determine what that value would be optimal, the fact

Now that I think about it more, when I've seen it happen before, it tends to be on projects that use dependabot / renovate. If any of those updates depend (directly or transitively) on a later version of Go, the go.mod would be bu

Just watch as most libraries now update their go.mod to say 1.25, despite using no 1.25 features, meaning those who want to continue on 1.24 (which will still have patch releases for six months...) are forced to remain on older versions or
