You should read this to understand how the economics of this works: https://stratechery.com/2021/cloudflares-disruption/

"The reason that Cloudflare can pull this off is the same reason why S3’s margins are so extraordinary: bandwidth is a fixed cost, not a marginal one. To take the most simplified example possible, if I were to have two computers connected by a cable, the cost of bandwidth is however much I paid for the cable; once connected I can transmit as much data as I would like for free — in either direction.

That’s not quite right, of course: I am constrained by the capacity of the cable; to support more data transfer I would have to install a higher capacity cable, or more of them. What, though, if I already had built a worldwide network of cables for my initial core business of protecting websites from distributed denial-of-service attacks and offering a content delivery network, the value of which was such that ISPs everywhere gave me space in their facilities to place my servers? Well, then I would have massive amounts of bandwidth already in place, the use of which has zero marginal costs, and oh-by-the-way locations close to end users to stick a whole bunch of hard drives."

I get what you are saying now. Agree if the right actors are on it, all those doesn’t matter. Sorry about that.

Yeah, but that could be another sequel. D1 is one minus D2

Also, the number of lines of kernel code being executed is not a valid metric without comparing how much of those code flow can the user control. In gVisor, this is mostly limited to what the go runtime can call. There is very little direct control over these syscalls.

+1. I'd also add that gVisor's slightly limited compatibility is a security feature. Like there is no need for obscure functionality which most production apps rarely use.

New comment by vayne in "TwitGrid – A simple, broadsheet layout for reading Twitter feeds"

I run a few bots which notifies on Slack/Discord. I think a Tweetdeck like grid would make more sense for them. Since these notifications are sometimes a little too chatty, I think it sits in-between a Tweet and Notification.
