Lossless Float Image Compression

news.ycombinator.com Unknown 2025-07-31 09:12:21

Back in 2021 I looked at OpenEXR lossless compression options (and I think my findings led a change of the default zip compression level, as well as change of the compression library from zlib to libdeflate. Yay blogging about things!). Then in 2023 I looked at losslessly compressing a bunch of floating point data, some of which might be image-shaped. Well, now a discussion somewhere else has nerd-sniped me to look into lossless compression of floating point images, and especially the ones that

This might be the next must-buy Android gaming handheld, and it’s not a Retroid

androidauthority.com Unknown 2025-08-04 08:16:14

TL;DR The ANBERNIC RG 477M is an upcoming handheld with a compact form-factor. If naming conventions hold true, it has a 4.7-inch panel and a Dimensity 8300 chipset. No release dates or pricing have been announced yet. One of the main reasons to buy an Android gaming handheld over a Linux-based one is increased power for PS2 emulation and above. Until recently, only Retroid and a few others offered devices powerful enough for reliable PS2 emulation, but the latest device announced by ANBERNIC

Bold Mission to Hunt for Aliens on Venus Is Happening

news.ycombinator.com Natalia Mesa 2025-08-01 05:45:56

A UK-based mission is aiming to settle, once and for all, whether life exists on Venus. The mission plans to send a probe to the planet in search of microbial life, not on the surface, of course, but in the Venusian clouds. Over the past half-decade, scientists have detected the presence of phosphine and ammonia—two potential signs of biological activity—in Venus’s clouds. On Earth, both gases are produced only by biological activity and industrial processes, and scientists are unsure of their

You should stop putting your phone face up on the table - here's why

zdnet.com Chris Bayer 2025-08-04 14:00:14

Sabrina Ortiz/ZDNET A friend of mine recently told me, "I always keep my phone on silent mode… which doesn't matter because I compulsively look at it every three minutes anyway." He's not the only one. From becoming a text addict to having full-blown smartphone dependency, the urge to look at and interact with our "flat things" has been deeply ingrained into our collective behavior for some time now.

East Asian air cleanup likely contributed to acceleration in global warming

RAMIP simulations and recent emissions changes in East Asia We first document the emissions perturbation applied in the RAMIP baseline and East Asia simulations21 (see “Methods”), and compare them to the actual emissions reductions from the same region since around 2010. Briefly, RAMIP isolates the climate effects of aerosol emissions in one region by comparing two sets of transient emission simulations; one following a global, high emissions pathway (SSP3-7.0, which assumes weak air quality po

Black hole merger challenges our understanding of black hole formation

Earlier this month, Hollywood mourned the passing of Michael Madsen, a gifted actor best known for his critically acclaimed roles in Reservoir Dogs, Kill Bill, and Donnie Brasco, among others. Few obituaries have mentioned one of his lesser-known roles: a black ops mercenary hired to help hunt down an escaped human/alien hybrid in 1995's Species. The sci-fi thriller turns 30 this year and while it garnered decidedly mixed reviews upon release, the film holds up quite well as a not-quite-campy B

Hill Space: Neural nets that do perfect arithmetic (to 10⁻¹⁶ precision)

When understood and used properly, the constraint W = tanh(Ŵ) ⊙ σ(M̂) (introduced in NALU by Trask et al. 2018 ) creates a unique parameter topology where optimal weights for discrete operations can be calculated rather than learned . During training, they're able to converge with extreme speed and reliability towards the optimal solution. Most neural networks struggle with basic arithmetic. They approximate, they fail on extrapolation, and they're inconsistent. But what if there was a way to m
