You can, but the interesting thing about AF_XDP is that you've got a userland path to writing directly to the card's DMA buffers; TC BPF still allocates an skbuff for every packet …

Understandably buries the lede that the stranded ship hadn't issued a distress call.

He laughed.

There's a state where a municipality can define a felony?

They haven't. Excepting RC4, which is wildly different from every other mainstream cipher, the track record of practical block cipher cryptanalysis (of core algorithms) is meager. …

"Omelet" is the right (and classic) analogy here.

There's really not much to it? Stick it in a low oven and bring it just under temp, then finish it in a ripping pan. If the results you're getting from that aren't restaurant-calib…

You're right: I'm not taking seriously the idea of "emotional truth".

Plot a line from CHI1 to all of the nearest houses and get back to me with the the prices. I did one ray from CHI1 to Molitor Road and the first house I hit was over a half mil. Te…

Respectfully, I've done this recently and I don't believe you, but I'd be happy to place a bet with you and then drive out there and take decibel readings (I can go grab some hardw…

There was an opportunity to organize and exploit market power back in 2017-2018, when there was a frenzy of recruiting and growth in the industry. The field was also much more ideo…

At this point you're basically making an argument against all commercial real estate.

Again, this isn't unknowable, you can literally just pull up next to CHI1 and open your window and listen. You won't hear anything.

I don't know what you think this link shows, but you can just jump to CHI1 on Google Maps (or, you know, drive there) to see what that area looks like.

I can't get past the premise here that data centers are using material amounts of water. You took all the time to write this, but then included an assertion I think we all broadly …

I'd love to see a Google Maps picture of a large, attractive parking lot.

No, it's not the same! At least not at the data centers I've seen. Go look at the Aurora CH1 CyrusOne DC and then beam yourself down 88 a bit to the nearest office building and com…

First, no, all these buildings have wildly overprovisioned parking. Most of the lots are empty. I'd encourage people wondering about this to just go drive out to an office complex …

I'm a housing activist (we're fourth and inches from getting Oak Park to be the first municipality in Illinois to outlaw single-family exclusive zoning) and from grim experience I …

Office buildings are not more attractive than data centers; that's my whole argument. In format, massing, and design, data centers essentially are office buildings, just with drast…

I've lost track of what your argument is. Mine is that office buildings are not generally filled with workers from the immediate municipality in which they're situated. We're talki…

When we're talking about things like AES and SHA2, a common answer among experts to (1) is "probably no". (That's not a common answer to the same question about, say, ECDLP, even l…

No. You can drive right into the parking lot of a CyrusOne data center in Aurora and listen. You're not going to hear anything. Nobody is disputing that Elon Musk or whoever has bu…

The office buildings next to the CyrusOne data centers in the western suburbs are not filled with people from Aurora. They're filled with commuters.

You made a categorical claim. We can't both be right; one of us has to be wrong. So what's false in the report I just linked to?
