Yplasma zaps the air to cool chips for data centers

techcrunch.com Tim De Chant 2025-08-27 08:40:00

If you didn’t know any better, you might think it’s magic. David Garcia gave TechCrunch a demo video demonstration of a device developed by his company, Yplasma. A row of five candles sit in front of a harmonica-like device with wires hanging off it. Suddenly, the flames flicker and then snuff out. Inside the device, two strips of copper coursing with electrical current are generating plasmas, or clouds of charged particles, that induce airflow through the cavity and out over the candles. It’

Maria Diaz/ZDNET Are you a cord-cutter? The last time my family paid for cable TV was in 2017. Since then, we have watched all our TV entertainment on streaming services. While some shows are still difficult to find, nearly everything is available if you're willing to look for it or pay for it. If you watch TV via streaming, you need a device to download and present the stream. Most smartphones, tablets and computers have apps that will do this.

Anker’s 12-in-1 Dock and Monitor Stand Combo Gets a Prime Day Cut as Amazon Clears Out Stock

gizmodo.com Joe Tilleli 2025-08-27 12:25:14

Prime Day is a go and Amazon right now is firing off on all cylinders. You can save a ton on a load of different products across every category. This is a great time to browse through some deals and find a cool thing you never thought you needed until you saw it. That for me is this Anker USB-C docking station. Now a docking station isn’t all that special or crazy, but what grabbed my eyes about Anker’s 675 is its shape. This docking station doubles as a monitor stand. Right now, it’s going for

Moroccan founder raises $4.2M for her YC-backed startup building the next layer of AI search

techcrunch.com Tage Kene-Okafor 2025-08-27 12:00:41

As generative AI reshapes industries, one of its most important yet invisible challenges is retrieval, the process of fetching the right data with relevant context from messy knowledge bases. Large language models (LLMs) are only as accurate as the information they can retrieve. That’s where ZeroEntropy wants to make its mark. The San Francisco-based startup, co-founded by CEO Ghita Houir Alami and CTO Nicolas Pipitone, has raised $4.2 million in seed funding to help models retrieve relevant da

The HBO streaming video app became HBO Max when the company added Warner Bros movies and Turner TV shows. In the worst rebrand since Twitter became X, the company later dropped the unique and valuable HBO part of the name and kept the generic and worthless Max part. Two years later, the company is fixing that.

Show HN: Dev atrophy test – Can you still code without AI?

Hey HN, I'm Per from Scrimba (YC S20), the code-learning platform. There's been a lot of talk lately about whether AI tools are causing skill atrophy amongst developers. We get a front-row seat to this, and we see more and more students struggle with basic concepts, and building apps on their own.

Proposal: GUI-first, text-based mechanical CAD inspired by software engineering

news.ycombinator.com Unknown 2025-08-24 08:37:00

Most mechanical CAD tools (SolidWorks, Fusion, FreeCAD) still lock all modeling into opaque binary files. That makes it hard to track changes, collaborate with Git, or automate builds. I’ve written a proposal for an alternative paradigm: - GUI-first, like KiCad - visual modeling is the default - Text-based source files (YAML/JSON) — readable, diffable, Git-friendly - Separation of source and result - .step, .stl and previews are built artifacts - Parametric logic is explicit - slot width =

From Point Clouds to Photorealism: How PRoGS Advances the State of Neural Rendering

What if a real-time automated decision-making process needs a computer vision system to produce photorealistic visuals in a mere fraction of a second? In many cases, this requires too much computational power — if it’s even possible at all. When computer vision uses 3D Gaussian splatting (3DGS), it provides a photorealistic image, but the process takes far too long.
