I can think of ways to approximate FQ on an input-queued switch while maintaining performance, but it doesn't really help because the total number of queues being a function of the traffic still opens you up to resource exhaustion atta

It's interesting how long we've been waiting for fair queuing to fix congestion problems in the Internet. The first proper research on this was published in 1989: https://dl.acm.org/doi/10.1145/75246.752

At the edge, if Brutal comes up against FQ-Codel or Cake in your (recent) Linux router, then if it causes congestion it should shoot itself in the foot, and other traffic shouldn't see too much adverse impact. When Brutal is limited t

The Internet only works because TCP (and QUIC) congestion control does a reasonable job of matching offered load to available capacity. Without congestion control, the network is apt to get into congestion collapse, where the network is in

The Royal Society produced quite a good policy brief on green ammonia a couple of years back. Does sound very promising for a number of industries. https://royalsociety.org/-/media/policy/projects/green-

A little over 30 years ago when I started working on multimedia conferencing over the Internet, for some reason we had a couple of hardware JPEG decoder ISA (?) cards from Bitfield Oy, a Finish company (if I recall correctly). I can't

You can avoid being used for amplification attacks by simply requiring the request packet be at least as large as the response. Burns some extra inbound bandwidth and doesn't protect you from DoS attacks on your server, but at least a

Under light to medium loads, roundabouts are preferable to junctions with stop lights, as you rarely need to wait long to enter the roundabout. But under high loads, they can cause starvation when there are no breaks in traffic along the m

If 2.8 billions tonnes isn't enough, can we just spray additional olivine powder over the surface of the ocean? Presumably it would lock up CO2 in the seawater just fine, allowing more CO2 to be absorbed by the ocean from the air.

With the cup, I moved the doughnut up from below, and just eyeballed when the area above the midline of the cup equalled the area in the hole. Turns out I can do this fairly accurately.

Got 99% perfect, 6 perfect cuts, on my first attempt. A couple of the perfect ones, I thought I'd be close, but was surprised to be perfect.

I think the correlation between vehicle weight and injury to pedestrians requires some nuance. The comments in the article imply that being hit by a heavy vehicle involves more force than being hit by a light vehicle but, other things being

> 500 Gbit/sec, that used to be the domain of entire ISP's core switches And then you realize that the latest datacenter Ethernet switch chips have 51 Tbit/sec agregate non-blocking capacity (128 ports of 400Gb/s, or

Despite how rediculous Tesla's repair bill is, when someone comes out with a quote like that, suddenly I find my sympathy draining away.

Yes, his question assumes an answer. Sure, I can force the year onto a circle, but that's not how I think of it. He really should not have assumed a circle in the first place if he wanted to know what people really think.

If I understood correctly, they are claiming that Epic effectively laid off everyone and sold some of the assets to SongTradr. SongTradr then made offers to half the previous employees. As these people were not previously SongTradr employe

After smashing the glass back on a Nexus about 10 years ago, all the phones I've bought since have been mid-range Android phones with plastic backs. Currently have a OnePlus Nord 2T - excellent phone. I'm probably atypical, but

Dandelions are pretty and seem to survive far better in my lawn than grass does. So dandelions it is. Can't imagine having neighbours that would complain.

I'm very similar to you - I can't consciously visualize - I just get a blank when I try. But I can lucid dream, and then I can visualize perfectly, even designing complex 3d mechanisms. When I'm fully awake, I'm sort o

I wish the languages I use would not only provide static strong typing, but also proper explicit support for units. Automated dimensional analysis would prevent many of the bugs I've written over the years, and there are so many times

And in most places, what they lose on fuel theft, they more than make up on sales in the petrol station shop which is where they really make their money, so they have little incentive to change.

For brakes at least, electric vehicles should permit brake emmisions to be reduced significantly. First, you've got regenerative braking, so no real need to use friction brakes except when braking too hard for regen. But as you'

Doesn't it at least seem odd that Google can't infer a road is impassable, when no vehicle it has been navigating has ever made it across the bridge in the last nine years? Seems like something that shouldn't be impossibly h

Seems like this is mostly about making sure that Intel Foundry customers who will inevitably use lots of ARM processors are well supported.
