U.S. bill could make foreign piracy sites impossible to access.
A new Republican bill would target foreign sites distributing pirated TV shows, movies, anime, sports, books, software and more. Court-ordered blocking could reach ISPs, DNS providers and certain large VPN services, meaning a VPN may not bypass it.
Micron just hit 512GB on a single DDR5 server DIMM
Its new RDIMM reaches up to 9,200 MT/s and cuts operating power by over 60% vs. four 128GB modules. A 24-slot dual-socket server could reach 12TB of DDR5. AMD/Intel validation is underway, with volume production expected in H2 2027.

#Tech is not enough alone.
It needs to be more socially social (#develop people, not just #dev tech).

Citizen Astronomy (CAst)
by ÖgetayKayali
https://github.com/OgetayKayali/citizen-astronomy
Every clear night, amateur telescopes around the world capture photons that professional observatories never will -- the right patch of sky, at the right moment, with enough patience to notice something change. Citizen Astronomy turns those images into science.
CAst is a desktop application (Windows installer primary; unsigned macOS .app zip available for alpha testers) that takes folders of FITS and XISF images and gives you the tools to measure variable stars, discover moving asteroids, build Hertzsprung-Russell diagrams, and explore the sky -- all from one guided interface, no command-line scripting required.
Please read more details in ALT-Texts of images. These images are just a few examples of the sophisticated use-cases of this software!
Another nice example:

Differential Photometry
Example of produced light curves in Citizen Astronomy (CAst)
Open a folder of time-series images, and CAst scans your frames, identifies field stars through Gaia DR3 and VSX catalogs, performs aperture photometry with adaptive FWHM-scaled apertures, and produces differential light curves. Fit periods with Lomb-Scargle, refine comparison stars, bin for signal-to-noise, and export science-ready AAVSO reports.
Alt...
Sky Explorer
Open any plate-solved image and turn it into an annotated field census. CAst queries SIMBAD, Gaia DR3, VSX, the NASA Exoplanet Archive, and JPL Horizons for objects inside your footprint, then overlays them on the frame with a searchable results table. Switch object-type modes from Simple deep-sky classes to Scientific SIMBAD codes, compare against DSS or Hα survey cutouts with an interactive divider, mark magnitude reach with Mag Limit, add manual annotations, export stills or comparison animations, and build size-aware object collages from catalog angular sizes.

The Sequencer: Detect one-dimensional sequences in complex datasets
The Sequencer reveals the main sequence in a dataset if one exists. To do so, it reorders objects within a set to produce the most elongated manifold describing their similarities which are measured in a multi-scale manner and using a collection of metrics. To be generic, it combines information from four different metrics: the Euclidean Distance, the Kullback-Leibler Divergence, the Monge-Wasserstein or Earth Mover Distance, and the Energy Distance. It considers different scales of the data by dividing each object in the input data into separate parts (chunks), and estimating pair-wise similarities between the chunks. It then aggregates the information in each of the chunks into a single estimator for each metric+scale.

Alt...
Shuffled image rows
The Sequencer reorders the objects in the input dataset according to a detected sequence, if such sequence exists in the dataset. A good example of a perfect one-dimensional sequence is a natural image: the rows within a natural image form a well-defined sequence. Therefore, we can shuffle the rows in a natural image, and apply the Sequencer to the shuffled dataset. The following figure shows the result of applying the Sequencer to a shuffled natural image. The left panel shows the original image. The middle panel shows the same image after we have shuffled its rows. The shuffled image serves as the input dataset to the Sequencer, where each row is considered as a separate object. The output of the Sequencer is shown in the right panel, where we reordered the rows according to the detected sequence. The Sequencer successfully identified the one-dimensional trend spanned by the different rows.

CLUES: Clustering tool for analyzing spectral data
CLUES (CLustering UnsupErvised with Sequencer) analyzes spectral and IFU data. This fully interpretable clustering tool uses machine learning to classify and reduce the effective dimensionality of data sets. It combines multiple unsupervised clustering methods with multiscale distance measures using Sequencer (ascl:2105.006) to find representative end-member spectra that can be analyzed with detailed mineralogical modeling and follow-up observations. CLUES has been used on Spitzer IRS data and debris disk science, and can be applied to other high-dimensional spectral data sets, including mineral spectroscopy in general areas of astrophysics and remote sensing.

PIRATES
(Polarimetric Image Reconstruction AI for Tracing Evolved Structures)
uses machine learning to perform image reconstruction.
It uses MCFOST to generate models, then uses those models to build, train, iteratively fit, and evaluate PIRATES performance.
Optical interferometric image reconstruction is a challenging, ill-posed optimization problem which usually relies on heavy regularization for convergence. Conventional algorithms regularize in the pixel domain, without cognizance of spatial relationships or physical realism, with limited utility when this information is needed to reconstruct images. Here we present PIRATES (Polarimetric Image Reconstruction AI for Tracing Evolved Structures), the first image reconstruction algorithm for optical polarimetric interferometry. PIRATES has a dual structure optimized for parsimonious reconstruction of high fidelity polarized images and accurate reproduction of interferometric observables. The first stage, a convolutional neural network (CNN), learns a physically meaningful prior of self-consistent polarized scattering relationships from radiative transfer images. The second stage, an iterative fitting mechanism, uses the CNN as a prior for subsequent refinement of the images with respect to their polarized interferometric observables. Unlike the pixel-wise adjustments of traditional image reconstruction codes, PIRATES reconstructs images in a latent feature space, imparting a structurally derived implicit regularization.

The performance of PIRATES with signal to noise consistent with recent VAMPIRES NRM data, with no
algorithmic treatment to constrain the influence of noise. Visibilities and closure phases with injected noise and corre-
sponding error bars are plotted in columns 1 and 2. Stage 1 (CNN) does a good job of a moderate resolution and low
noise reconstruction of the ground truth (top row, columns 3-5), however, significant amounts of noise are introduced
into the images during the iterative fitting (middle row, columns 3-5). The ground truth images are displayed in the
bottom row, columns 3-5.
nazgul is a joint effort by:
* J. Michael Burgess
* Ewan Cameron
* Dmitry Svinkin
https://github.com/grburgess/nazgul
Nazgul is a framework for performing GRB localization via fitting non-parametric models to their data time-series and computing the time delay between them. It is currentrly built upon the magic of Stan and implements a parallel version of non-stationary Random Fourier Features. The idea is get away from heuristic methods such as cross-correlation which do not have a self-consistent statitical model.
The idea is that satellites throughout the Sol system observe gamma-ray bursts at different times due to the finite speed of light. This creates a time delay in their observed light curves which can be used to triangulate the gamma-ray burst position on the sky. These triangulation create annuli or rings on the sky which Nazgul searches for so that it, in the darkness, it can bind them to a location on the sky.

" A 12-year-old in California built a working printer for blind readers out of a Lego robot kit for his school science fair, after finding that the machines sold for the job cost about $2,000; the parts in his version came to roughly $350 in shops
A twelve-year-old just proved that assistive technology doesn't need to cost thousands when ingenuity and a Lego kit can do the job for under four hundred dollars."

@eff This is NOT all that is going on, EFF account-minder, and I reject your softened and euphemized framing of this issue. This isn't about "training" or "transformation" or any positive purpose, it's about capturing and destroying information, grabbing the books and other works and stuffing them into the machine and then making sure nobody else can use the stuff for their own rackets.
This is a fraud. The entire #tech sector is consecrated to CHEATING. You can't honestly say that there's a positive "transformative" purpose in the GenAI obsession.
There's no reason at all at work. Their thing isn't an "AGI superintelligence" and they know it. When do we stop pretending that this is just kind-hearted software engineers wanting to change the world? They exist, but not anywhere powerful in U.S. business or technology.
