If Multicast is the Answer -- What was the Question?
Multicast is (almost) as old as the Internet, having become a tool for increasing network efficiency but also enabling destination discovery in a number of key use cases, although misaligned economic interests have limited its deployment to domain-local usages. But recent advances in multicast technologies as well as the identification of new use cases for which IP multicast may be ill fitted yet network-level support may be desirable motivate to re-think old perceptions of multicast and its us…

How sweet and lovely dost thou make the shame
Which, like a canker in the fragrant rose,
Doth spot the beauty of thy budding name!
O! in what sweets dost thou thy sins enclose.
That tongue that tells the story of thy days,
Making lascivious comments on thy sport,
Cannot dispraise, but in a kind of praise;
Naming thy name blesses an ill report.
O! what a mansion have those vices got
Which for their habitation chose o…

First light on the ngscopeclient ILA integration including digital vector support up to 32 bits (up to 64 will come soon and is straightforward to add, bigger will be a bit more work since there's no native int type bigger than that)
Next step will be to make a protocol decode for APB to prove out the decode flow on digital buses

Abstract: Hydrogen Lyman-alpha (Ly$\alpha$) is a prominent emission line from the circumgalactic medium (CGM). Due to its resonant nature, Ly$\alpha$ carries imprints of the physical properties and kinematics of the cold CGM. In particular, CGM rotation can modify the Ly$\alpha$ peak separation, which is often interpreted as a tracer of H I column density. We present 3D Monte Carlo Ly$\alpha$ radiative-transfer simulations in a CGM-like rotating medium and examine how the emergent spectra depend on rotational velocity ($V_{\rm rot}$), H I column density ($N_{\rm HI}$), viewing angle, clumpiness, and intrinsic source width. We find that rotation broadens the integrated spectra and increases the peak separation, with the strongest viewing-angle dependence when rotational Doppler shifts dominate over frequency diffusion. At high $N_{\rm HI}$, numerous scatterings reduce the sensitivity of integrated spectra to rotation, producing a degeneracy between $V_{\rm rot}$ and $N_{\rm HI}$. Consequently, Ly$\alpha$ peak separation alone can overestimate $N_{\rm HI}$ in a rotating medium. Spatially resolved halo spectra provide a clearer diagnostic: opposite sides of the rotating medium show systematic redshifted and blueshifted asymmetries associated with the line-of-sight velocity of the last-scattering gas. Such rotation-driven signatures can also contribute to velocity-map patterns often interpreted in terms of inflow or outflow, highlighting the need to consider rotation in spatially resolved Ly$\alpha$ observations. We further show that the main signatures persist in simple clumpy media, while the halo signatures are largely insensitive to the intrinsic source width. Our results demonstrate that spatially resolved Ly$\alpha$ observation is essential for disentangling CGM rotation from radiative-transfer effects.

Sonnet 144 - CXLIV
Two loves I have of comfort and despair,
Which like two spirits do suggest me still:
The better angel is a man right fair,
The worser spirit a woman coloured ill.
To win me soon to hell, my female evil,
Tempteth my better angel from my side,
And would corrupt my saint to be a devil,
Wooing his purity with her foul pride.
And whether that my angel be turned fiend,
Suspect I may, yet not directly tell;
But bei…
