Four major US mobile operators have agreed to a series of undertakings designed to address concerns over airline safety and to allow them to use their C-band spectrum to its full extent.

The result of this effort, Intel Max Series GPU formerly known by the code name Ponte Vecchio, packs 100 billion transistors and 47 tiles onto five process nodes. Beyond that, they include two packaging innovations, EMIB 2.5D and Foveros 3D technology, and stack tiles atop one another for greater processor density.

What it is about is how very few companies have access to the raw AI models that are transforming the world, the curated datasets that have been purged of bias (to one degree or another) that are fundamental to training AI systems using machine learning techniques, the model weights and checkpoints that are key to tuning a model, and the money to either build or rent the capacity to bring the neural network software and the data together to train an AI model.

Intel has announced a new processor with 144 cores designed for simple data-center tasks in a power-efficient manner.

Data center fires aren’t common, but they can be devastating. As use of lithium-ion batteries grows, enterprises need to be aware of the risks, Uptime Institute warns.

Russian intelligence services, together with a Moscow-based IT company, are planning worldwide hacking operations that will also enable attacks on critical infrastructure facilities.

Back in the old days, there was a CPU and chip designers crammed everything into that single CPU, which made sense for the greatest number of customers offset against the additional cost of adding extra functionality.

Once upon a time there live a tribe who lived on the plains. They were an adventurous tribe, constantly wanting to explore. At night they would see the moon drift lazily overhead, and became curious.

If I’ve written in this space before about “convenience of the employer” rules a lot of late, it’s because they are so pernicious. These rules essentially require taxpayers who switch from working in-person in one state to working remotely in another to continue paying income taxes to the state they used to work in, not the one they currently work in.

A federal judge yesterday ruled that Google intentionally destroyed evidence and must be sanctioned, rejecting the company’s argument that it didn’t need to automatically preserve internal chats involving employees subject to a legal hold.

From a national security perspective, banning TikTok seems to be a reasonable step in protecting U.S. citizens. After all, TikTok is merely a video sharing app that is widely used by children; thus, its ability to harm us far outweighs its utility.

Hedge 171: Paul Grubb on Zero Knowledge Middleboxes

Middleboxes are used in modern networking to sniff out attack traffic (IDS), block unwanted traffic (stateful packet filters), and share load among several different servers. Encryption, however, is making it hard for the middleboxes to do their job. Paul Grubb joins Tom Ammon and Russ White to discuss zero knowledge middle boxes, which allow operators to enforce arbitrary policies on the underlying traffic of an encrypted connection without decrypting it.

Upcoming Training: How the Internet Really Works Part 1

I’m teaching How the Internet Really Works over on Safari Books Online on the 24th of March—in a couple of weeks. From the description:

This live training will provide an overview of the systems, providers, and standards bodies important to the operation of the global Internet, including the Domain Name System (DNS), the routing and transport systems, standards bodies, and registrars. For DNS, the process of a query will be considered in some detail, who pays for each server used in the resolution process, and tools engineers can use to interact DNS. For routing and transport, the role of each kind of provider will be considered, along with how they make money to cover their costs, and how engineers can interact with the global routing table (the Default Free Zone, of DFZ). Finally, registrars and standards bodies will be considered, including their organizational structure, how they generate revenue, and how to find their standards.

The general problem statement for technological standards is how to avoid the power imbalance of a single source for essential goods and services; in other words, standards are a line of defense against concentration risk. Interoperability is the goal, and multiple suppliers is the proof.

In this episode, they focus particularly on how social media has become a place where predators will search and highlight childrenâ€s vulnerabilities — which so many young people share online.

A decade ago, waferscale architectures were dismissed as impractical. Five years ago, they were touted as a fringe possibility for AI/ML. But the next decade might demonstrate waferscale as one of only a few bridges across the post-Mooreâ€s Law divide, at least for some applications.

This is not a ‘silver bullet’, however. In comparison to the sophisticated deception available in traditional IT security, deception in ICS still faces some challenges.

Two new separate sets of research released this month underscore real, hidden dangers to physical operations in today’s OT networks from wireless devices, cloud-based applications, and nested networks of programmable logic controllers (PLCs) — effectively further dispelling conventional wisdom about the security of network segmentation as well as third-party connections to the network.
