exhibit A / exhibit B
am i delirious or does this PHY just... not comply with the RMII spec??

two scope traces CH1: CRS_DV CH2: REF_CLK duration of low pulse on CRS_DV is 220 ns rather than 200 ns (5 MHz). this is 11 cycles of REF_CLK rather than 10
Loss of carrier shall result in the deassertion of CRS_DV synchronous to the cycle of REF_CLK which presents the first di-bit of a nibble onto RXD[1:0] (i.e. CRS_DV is deasserted only on nibble boundaries). If the PHY has additional bits to be presented on RXD[1:0] following the initial deassertion of CRS_DV, then the PHY shall assert CRS_DV on cycles of REF_CLK which present the second di-bit of each nibble and deassert CRS_DV on cycles of REF_CLK which present the first di-bit of a nibble.

TransLink and the City of New Westminster have completed major upgrades to a 737-metre stretch of the BC Parkway along Stewardson Way, between River Drive and 14th Street. These enhancements are designed to improve safety, comfort, and accessibility along this vital active transportation corridor.
Key upgrades include:
A widened pathway with separate lanes for cyclists and pedestrians making it comfortable and convenient for all modes of active transportation

A stretch of overhead track used by SkyTrain over a road junction with a bike lane in green and a cyclist crossing

An emergence-oriented approach to cyclic pursuit
In this paper, we explore the cyclic pursuit problem of unicycles and study circular formation from an emergence perspective. We first establish a systematic study on such formation and derive a necessary and sufficient condition for its existence. Building on this theoretical foundation, we design a distributed control law that enables the spontaneous formation of circular formations through only local interactions. Notably, key geometric features -- including the radius and agent spacing -- a…

A thing that puzzles me about biking, and how I bike, and how some apparently "Effective Cyclists" bike, is whether the belief in "the system" affects reactions to problems, or if there might actually might be something cognitive at work. A long-ago-friend of mine, when asked how to use a canoe, said, "don't fall out, don't hit rocks". This was flip and glib, but not all wrong, basically, avoid the two obvious mistakes, and keep doing that. When I sta…

The @… paper Algorithmic Alphabets for Patterns of Movement by @… @… me is published !

Algorithmic Alphabets for Patterns of Movement
In this paper we introduce initial work in making ‘algorithmic alphabets’ as hand drawn notation for choreographic live coding of robots, created within the Realtalk system. We briefly review some prior art as inspiration, before introducing our initial systems based on recognition of symbols within rhythmic cycles, sharing the trajectory of our ongoing work.

Once again: #FuckEricAdams
Unbelievable how he's managed to avoid jailtime breaking federal/state laws while City Council allows him to continue to break _their_laws as well.

No to 15 mph e-bike speed limit, yes to real safety! - Transportation Alternatives
A ridiculous 15 mph speed limit for e-bikes won't work. Tell Mayor Adams and City Council: We need effective, data-driven policies that protect everyone, and accountability for the corporations fueling chaos on our streets — not the cyclists surviving it.

Vanishing arcs for isolated plane curve singularities

Vanishing arcs for isolated plane curve singularities
The variation operator associated with an isolated hypersurface singularity is a classical topological invariant that relates relative and absolute homologies of the Milnor fiber via a non trivial isomorphism. Here we work with a topological version of this operator that deals with proper arcs and closed curves instead of homology cycles. Building on the classical framework of geometric vanishing cycles, we introduce the concept of vanishing arcsets as their counterpart using this geometric var…
