Suppose you had a index of 100 companys each with a market cap of 1 G$ for a total of 100 G$. You have passive investors owning 20 G$ of that index, amounting to 20% of the total, 20% of each company, and 200 M$ per company. You then rotate

I did provide a example: > You get a lease for a /N+K address. /N routes to your router which routes the last K bits just like normal as if it had a /N-M to a /N route. > This still sounds like a very bad mixing of

It is always a mystery how people just randomly misinterpret what I write. At literally no point did I mention port mapping. I am pointing out how the problem NAT “solves” is just dynamic address configuration. They have implemented a N+K b

Needing to punch holes in NAT is one of the most idiotic own-goals in the entire field of networking. NAT is effectively your router doing DHCP with a 17-bit suffix (16-bit port + 1 bit for UDP vs TCP) to each of your applications and then

I do not understand the point you are trying to make. The person you replied to showed how to evaluate it with simple math. 400 Gb/s is 50 GB/s. RTT of 300 ms would only require 15 GB of buffers. That would not even run a regular

Do you have citations for sustained 0.5 core-cycles/byte (80 Gb/s)? The benchmarks I have seen are closer to ~20-30 Gb/core-s though I have heard claims of 40-50 Gb/core-s.

uring supports zero-copy, but is not a copy-reduction mechanism; it is a syscall-reduction mechanism. Large buffers mean less syscalls to start with, so less benefit.

For point 1, as I noted here [1], total bandwidth and resources are dominated by large flows. Endpoints are powerful enough to handle these large flows. The primary problems would lie with poor intervening networks and setup overhead. For p

You have asserted without evidence that the increased certificate chain size is the primary scaling bottleneck. I assert that the bottleneck is most likely due to accidental complexity elsewhere on the argument that claimed problems look to

by Veserv 7mo ago
But do those connections constitute a material amount of total bandwidth and thus resources? No, as the article points out the median is 8 KB, but the average is 583 KB. The extra 15 KB for each connection would only bump server-side bandwi

You are not breaking H1, it just runs poorly in a different environment than the one it was created during. This is frankly already true which is why we literally have had two entire major versions since. A 160 KB congestion window with 50

Exactly, HTTP/1.1 is a poorly designed protocol and there are good reasons why we have newer versions of HTTP which avoid multiple unnecessary encryption handshakes. Exactly, using a blanket default initial congestion window of 16 KB i

by Veserv 8mo ago
That is exactly the type of poor design that I was saying should be rectified. You can already configure your initial congestion window, and if you are connecting to a system expecting the use of PQ encryption, you should set your initial

While I appreciate more efficient and compact representations, I fail to see why this is particularly necessary. This article [1] on the same topic indicates a naive PQ chain is only ~40x the size of a current 4 KB chain. That means it is j

As @vitus points out [1], these numbers are pure, unadulterated garbage. Instead of being data, they are wildly incorrect extrapolations from this [2][3] actually useful and relatively correct past data. 2,000 bytes over commodity network i

In some senses, that is true of every scheme; you need to ensure you capture all non-determinism and that can be done with either more capturing or less non-determinism. However, the restrictions for generic replay-based time-travel debuggi

So a application that wants to filter will categorize their services privately and then write custom filtering logic, but will not just categorize their services publicly? That is nonsense. And your point about fail open versus closed also

Even ignoring everything else, at a minimum it is backwards. There is no reason to tell the application, and by extension their developers, how old the user is. The application should tell the user what bracket it is appropriate for and the

The last time this did the rounds (before the post got flagged into oblivion)[1] I did my own analysis [2]. When normalized by vehicle-years it was actually closer to 40x worse than the Pinto, not just 17x as stated in the article. [1] htt

The vertical axis of that latency graph has units in microseconds. Surely it meant nanoseconds?

I do not see how that follows. Memory bandwidth is measured in the hundreds of Gb/s. You can issue tens of unnecessary full memory copies before you bottleneck at a paltry 10 Gb/s. It is much more likely there is something else te

You can, just use tamper-proof VR headsets. To defeat that you would need to sneak a camera in front of your eye. You could then protect against that by using eye-tracking VR and putting those cameras on double duty to detect lenses inside

Ah yes, instead of applying the normal legal standard of “not even having the appearance of impropriety” we instead apply the monkey’s paw standard of waiting until they “no longer even have the appearance of propriety”.

Yes, those are bad as well. Are you seriously taking as your moral foundation that we need to poison the water supply to ensure executives get their bonuses? Is that somehow not utterly depraved self-enrichment?
