Like look okay so when you put a prompt in it gets preprocessed and postprocessed. You put "write a sentence about scary skeletons" into chatGPT or whatever, and before it touches the word plinko it gets changed- a whole screed of "guardrail" preprocessing gets put in front of it.

I don't have sources, but I expect it was only when random people on the street got access to cameras and could send their film in to get developed /exactly as it was taken/, with results close enough at a glance to the postprocessed professional photos, that we started assuming an "inherent" truth.

Not seen circular interpolation in postprocessed code for years. What do you use for programming?

i was talking with a few folks about this recently- does anyone have any good recipes for cellular noise with rectilinear edges? this is max(abs(dx), abs(dy)), which has ortho and diagonal edges and maybe could be modified (or postprocessed?) to be rectilinear...

Christmas has arrived early!

The HRRR-based SPC Mesoanalysis, and RRFS North America Domain forecasts postprocessed by the mesoanalysis routines, are on NOMADS!

It’s in its parallel evaluation until early October. Then it’ll be operational.

Patrick Marsh @pmarshwx.com · Sep 9

New offerings from SPC. You can check them out on NOMADS. Including, for the first time, our mesoanalysis grids (in netcdf format). We also use our mesoanalysis code to post-process the entire RRFS domain for every forecast hour and every initialization. nomads.ncep.noaa.gov/pub/data/ncc...

Vintage Thassos

Photo actually taken in 2015 with a Sony a330 and edited to give it a vintage look with wear and tear with ON1 Photoraw

Sometimes adding age gives a nice feel.

Experimenting again - This was inside The Hive Installation at Kew Gardens. Monochrome with some motion blur.

Camera was Olympus OM-D E-M10 Mkiii and post processed in On1 Photo Raw 2026

@aly.codes

yeah I was gonna say I don’t think you can actually turn the pipeline totally off, I mean if you did you would literally get just nothing. Even RAW is postprocessed in some form (it just has all the data available, and cameras tend to make it more neutral)

quasi-optimal convergence rates, where a suitable treatment of possible nonhomogeneous Dirichlet boundary conditions is pivotal to avoid loss of accuracy. Moreover, based on the properties of a postprocessed approximation, we derive a [3/4 of https://arxiv.org/abs/2501.11494v1]
