How does that work for identical twins?

The Polestar 2 is pretty good in this regard. All the most important things are on the steering wheel stalks, steering wheel buttons, and a few buttons for things like demist, play/pause and volume control on the centre console. Ther

Yes, I think it is quadratic. I don't claim it's practical (the original isn't practical either though), but just that the dependency on filenames isn't fundamental.

You could do the same spitting trick but only split at progressively increasing file lengths at the character '5'. The "compression" would be worse, so you'd need a larger starting file, but you could still satisfy

It's already happening. For the more demanding workloads such as AI training, RDMA has been the norm for a while, either over Infiniband or Ethernet, with Ethernet gaining ground more recently. RoCE is pretty flawed though for reason

RFC 791 which defines IP talks about both packets and datagrams. IP sends datagrams. Each IP datagram is fragmented into one or more packets depending on the underlying L2 network. But RFC 791 dates from when the underlying L2 network was

Yes, it was a poor choice of name. It was originally just a placeholder in the htsim code, from New Datacenter Protocol, but we avoided choosing a better name for too long and had already talked about it as NDP to enough people (especially

It's taken a while for spraying and trimming to go from being a crazy research idea to mainstream in UEC, but if you're interested, the old animations from my Sigcomm 2017 talk still give the general idea: https://www.y

Yes, it was a big deal when I was in school in the 70s. Everyone played. There were never any conkers left unclaimed under any Horse Chestnut within a mile of the school. We all tried lots of tricks - soaking in vinegar, baking in the ov

That's true, except it neglects the cost of the launch tower itself. If you botch a catch and need to rebuild the launch tower, that could get very expensive, both in immediate costs of rebuild, plus in opportunity cost of missed laun

As to whether catching the booster adds risk - I'm not sure it does. First, to the extent the booster is out of position in the x (sideways) direction, the chopsticks can move to accomodate error. But actually I think this dimension i

The Nobel prize cannot go to a team so they have to pick individuals. This is true for many (most?) nobel prize awards. Consider for example the discovery of gravity waves - the team that built and operated LIGO was huge, but they have to

I'm not a fan of Drax (is anyone?), but I guess the alternative is worse, at least for now. In the short term, the marginal alternative is LNG, also shipped in oil-fueled cargo ships. So as we continue to build out wind and solar and

The graph in the article makes clear that isn't really true. Around half of coal use was replaced by natural gas in the 1990s, as you say. That's still a win - same energy, but half the CO2 emmisions. But since 2010 or so, the

"Let’s consider a trivial example: struct { int a; time_t b; int c; }; With 32-bit time_t, the offset of c is 8. With the 64-bit type, it’s 12." Surely it's 16 not 12, as b needs to be 64-bit al
