Linked-list freeing need not all happen in one go. There can be a queue of free-but-not-zeroed, push RC=0 stuff there instead of recurring on referents, anyone doing memory allocation work can pop a few items off that…
s/platforms/functions and types, noticed that too late to edit.
All the methods tagged as "zero-cost" compile to movd or less. The earlier version of archsimd (1.26, for amd64) supported these as direct "AsFooNxM" methods, and there were a lot of them. I am not 100% satisfied with…
Binary size only scales for the simd-touching platforms, with scaling depending on platform. Each platform gets emulation+number-of-variants. Emulation is there as an option, primarily for testing (do you trust us? I…
Depends how you define "equal". One approach is simply to scale the charge by income -- effectively, convert time to money, and charge you a congestion tax of some amount of money-earning time. "6 minutes" is 1/10000 of…
author here, you are right, I missed that. In my pathetic defense, the normal argument around here (Cambridge, MA) is about literal lane widening and narrowing, and not adding and subtracting.
Hi, author of the article. I'm assuming urban traffic speeds, which is what I observe all the time myself, but you can look at the video of those kids, and count, and look at the seconds. 125 bikes in 45 seconds,…
The way to view it is "unless there is syntactic sharing, it is a for loop, same as before". The compiler uses a syntactic test (with little knowledge of control flow or value use) to exclude loops from the change. This…
How do you get mm-wave radiation to an aquatic plant? Skin depth at that frequency is tiny. Are they doing studies on duckweed? (Look up the plant, indeed, they are.) And I can see how pine needles might be more…
Speaking both pedantically and based on my experience riding a bicycle, when traffic speed is reduced all the way to zero, it is in fact safer, at least for me. I am of course, not counting the risk of drivers stroking…
I think it's a three-part problem. One, it is a flow problem, and by removing congestion at one bottleneck you mostly deliver traffic more efficiently to the next bottleneck. Actually increasing traffic flow is much…
As someone else pointed out, reducing peak speeds does not necessarily increase travel time. See this report on the Prospect Park West redesign: http://jonathansoma.com/ppw/ I commute-by-bike on a road with bike lanes…
