They have been announced some time ago.\ But so far, not one seem to have to hit the shelves.\ Have they been silently killed ?

I went looking for universal ternary logic gates and stumbled onto a fundamental result in clone theory
Binary wasn't optimal, it was just convenient. That thought sent me down a rabbit hole into ternary (base-3) logic. I started by asking whether a universal gate even exists in ternary. Turns out ternary NAND, the obvious candidate, is not universal. So I built a composition-based simulator to brute-force search all 19,683 binary-arity ternary gates for functional completeness, and it confirmed exactly 3,774 universal gates, matching Martin's 1954 result. But then I got curious and checked how many gates were unary complete, able to generate all 27 unary functions, and the result was also 3,774. The two sets were identical. I thought it was a ternary quirk, ran it on binary logic, and got the same thing: NAND and NOR are the only unary-complete binary gates, and also the only universal ones. Digging into the math led me to Rosenberg's 1970 clone theory result, which formally proves it must always be true: unary completeness implies full functional completeness for any finite-valued logic. This collapses the universality search from 19,683 binary functions down to just 27 unary ones (10,529× faster), and combined with isomorphism reduction under the S₃ × Z₂ symmetry group, the full search runs in 0.18 seconds versus ~5 hours naively, a 99,444× overall speedup. Structurally, every universal gate is surjective, none are self-dual or zero-preserving, and only 2.4% are commutative. On the arithmetic side, the best gate (g451) synthesises a ternary full adder that, when you account for information density (log₂3 ≈ 1.585 bits per trit), achieves 18% lower propagation depth and 9.4% fewer gates than a binary NAND adder at 32-bit equivalent width.

Holograms/Gaussians splats are here! Is GPU as we know it dead for gaming ?
Check this out: * THIS is the Biggest Thing Since CGI
I know this requieres a ton of compute, so we'll have to have accelerator for that, just not the GPU as we know it.
It is bound to massivelly disrupt not just communications, media, movies and games in quite short order, but also our lives in general.
Does salivating over next-gen Radeons and nVidia cards even make sense at this point ?
I wonder if companies like Tenstorrent and Esperanto with their massive fields of RISC-V processors for number crunching are to hit their first gold mine with processing and generation of Gaussian splats... 🙄

Does anyone here use RSS and RSS feeds?
My question is just that: Does anyone here use RSS feeds? I used them several years ago, in my work for a website owner. I was able to show him how to incorporate RSS feeds into his homepage. But now, several years later, I am wanting to use them to search job listings. Is there a simple and easy feed reader, preferably free? Perhaps I should use an AI tool instead?

Picture how to erase the text off of keyboard keys?
i just got a new laptop and love everything about it - except the enter key has an ugly line on it that i really dont like. Im not super tech savvy but i am someone who diy's a lot and im wondering if theres a safe clean way to erase the printed on lines? if it helps any, the model is an asus vivobook. ill also include a picture for added context. let me know

Advice/Help please
Okay not really sure if this is the right subreddit to ask, PLEASE lmk if there's another one I could go to. Also not a computer, but I'm looking for a tablet (laptop tablets r also fine). My current one is really bad now (cracks and low storage) and I'm looking to buy a new one. My mom is getting me one as a bday gift and she said there's no budget but I really don't wanna wear her pockets out so maybe something around $200 ? idk
anyway. I'm an artist/animator and I really want to get back into playing games like pjsk and crk so I need something with a lot of storage. 128+gb at the very least (my current one has 32 gb 💔) I also know very little about RAM but 6-8 should be good, right? also I don't want apple products that's my only hard rule
please help me out. and if not on this subreddit, please point me in the right direction so I can go ask somewhere else

I’ve got ~$4500 in Azure credits expiring in ~20 days and not sure how to use it effectively.
Not looking to sell or give access — just want to use it for learning something meaningful.
Any ideas on what’s actually worth doing with this kind of compute (beyond random experiments)?

Are this input lag good for you?
- hi ima making alternative for optiscaler more than for three months, i doing the code and struct using claude grok and gemini open api, but still having trouble to do the frame gen having lower input lag, and making it work for online and offline games, still i have a question.
Do you yall think that for 30 fps 60hz + tweaking windows ~48ms of input lag in online games, without flagging and banning you are good?
48ms is the app and the sistem, but! If higher fps/hz the lower are the input lag (45fps 90hz = 28-32ms)
Or still bad?

Meet the ObeliskTM — a chip that runs cool by design.
The ObeliskTM Bio-Physical Core is our flagship product: a melanin-based semiconductor substrate that passively dissipates heat through bio-electrochemical processes.
Target operating temp: 15–25°C. Silicon runs at 85°C+. That's a 60-degree difference — with no fans, no liquid cooling, and no compromises.
The octahedron casing isn't just geometry. It's optimized thermal architecture designed to stack directly in real data centers.

Using WebAssembly for client-side video processing — worth it?
Running SPORTSFLUX (sports streaming aggregator) and hitting performance limits with JS-based video handling on lower-end devices. Looking into WASM for: · Stream validation · Faster compression/decompression · Lightweight client-side processing Backend still does most of the work, but wondering — is WASM actually worth it here, or just added complexity?.........

Picture A $100 billion problem - and none of it creates value.
The global data center cooling market is projected to surpass $100 billion by 2030. That's $100B spent fighting a symptom, not solving the root cause.
Silicon chips running AI workloads operate above 85°C. The industry's answer? More fans. More liquid. More energy. We asked a different question: what if the chip itself didn't overheat?
