That's exactly the issue. I'm just pointing out that it's a fantasy to hope for simple numbering of max supported speeds will simplify the current USB mess.

It will not.

Consumers would expect plugging a 20Gbps device into a 40Gbps port should result in 20Gbps negotiated speed. In reality it will mostly likely end up at 10Gbps (or less) because of the mess.

> mark the speed on the USB ports, removing ambiguities

Unfortunately it's not true.

Quiz: what happens when a device capable of 20Gbps is plugged into a port marked as 40Gbps?

Not true. In recent years smartphones do not advance much, and would be perfectly fine to keep working if not for the dying battery.

> At the very least we'd need to see some data that shows that most people replace batteries when it is possible to do so.

The degree of "possible" varies greatly depending on the available expertise and spare parts. Right now in EU it's cost prohibitive for both coz the special labor required is expensive and almost no official spare parts for consumers. So of coz this will be no data to support your claim.

How do you achieve that on macOS then? With PF?

>> The macOS version uses deep packet inspection to do this more reliably. That's not an option here.

I thought it would be easier to do DPI on Linux than macOS. No???

New comment by riobard in "Reverse-engineering the UniFi inform protocol"

riobard — Tue, 10 Mar 2026 09:14:11 +0000

Seamless WiFi roaming is mostly a client decision. The best you can do on AP is to:

a) optimize signal strength for coverage (stronger signals aren't always better in multi-AP deployment);

b) provide hints via 802.11k/v/r to help clients make, hopefully, better decisions;

c) forcefully drop and disassociate clients when signal is weak enough.

But if the client has bad WiFi implementation, there's nothing much you could do.

OpenWRT currently supports 802.11k/v/r, but optimizing coverage by adjusting signal strength and channels is left for experienced users to deal with manually. There is the are where some commercial offerings will do, but the result greatly varies. AFAIK there's no ideal system anyway coz physics is hard.

I used to think that the scenes of the TV series “Person of Interest” were exaggerated for storytelling purposes. Maybe not and it was accurate prescience.

"(sftp) packetizes the data and waits for responses, effectively re-implementing the TCP window inside a TCP stream."

why is it designed this way? what problems it's supposed to solve?

I hate the original Mac Pro case so much!!! The metal box is so heavy and the edges of the aluminum top handle is so sharp that you definitely need a pair of heavy-duty gloves to move it around.

China has already reserved the entire 6GHz for cellular and vehicles.

riobard — Mon, 13 Oct 2025 13:48:40 +0000

The assumed mentality of “being flexible” is the very reason WireGuard was created to fight against in the first place, otherwise why bother? IPSec is already standardized and with wide-spread hardware implementation (both FPGA and ASIC) and flexible.

Those pesky WD bridges usually support USB Bulk Storage only but not UASP, resulting in worse performance and higher CPU usage.

Also HDD power management is often complicated by the bridge chip sometimes intervening.

Not recommended for long-term use.

Yeah but those are pretty dated. I was under the impression those old Ampere servers are not efficient compared to modern EPYC anymore. So I’m wondering what their current generation of arm64 servers look like :p

What ARM64 machines are you using and what are they used for? Last year you were announcing Gen 12 servers on AMD EPYC (https://blog.cloudflare.com/gen-12-servers/), but IIRC there weren’t any mentions of ARM64. But now it seems you’re running ARM64 in full production.
