In late 2021, the term Web3 began to increasingly appear in mainstream media outlets. This does not refer, however, to a sudden increase in interest in the Semantic Web as defined by Tim Berners-Lee, but rather to something entirely different.
It also found affected hospitals had tens of thousands of outdated Windows 7 systems, and that the health system’s IT administrators failed to respond to multiple warning signs that a massive attack was imminent.

In a highly anticipated decision, a judge of the United States International Trade Commission ruled in August that Google infringed five patents owned by speaker maker Sonos. The case charged Google with copying Sonos’ patented technology in its Google Home smart speakers.
If you’ve followed the news over the last few years, you’re probably convinced that we’re living in a golden age of conspiracy theories and disinformation.
Americans, and not just Americans, are well aware of how deep the dysfunction of the ruling factions runs. Many older ones remember the abuses of the Intelligence Community and the warnings against the Military-Industrial Complex; they have lived long enough to see the political resistance to the Community and the Complex shift, under pressure of deliberate policies, from the Left to the Right.
The rumors spread like wildfire: Muslims were secretly lacing a Sri Lankan village’s food with sterilization drugs. Soon, a video circulated that appeared to show a Muslim shopkeeper admitting to drugging his customers — he had misunderstood the question that was angrily put to him.
Antitrust has not had its moment since the 1911 breakup of Standard Oil. But this past year, policymakers and government leaders around the globe have been taking a hard look at the technology markets.
For well over a decade, I have been arguing that governments should create IT accident investigation boards for the exact same reasons they have done so for ships, railroads, planes, and in many cases, automobiles.
Yet risks remain, and once the genie is out of the bottle, they are often difficult to manage and contain—they range from unintended consequences and side effects to threats to privacy and loss or misdirection of control.
How can we change the field of computing so that ethics is as central a concern as growth, efficiency, and innovation? There is no one intervention to change an entire field: instead, broad change will take a combination of guidelines, governance, and advocacy.
Jerome Pesenti, Facebook’s VP of Artificial Intelligence, explains the changes to the face recognition system that have accompanied the very recent brand name change from Facebook to Meta…
The dominant regime of the electric age—“democracy” mediated and managed by corporate journalists, academics, experts—is being slowly eaten by a new cybernetic order, mediated by algorithm and increasingly not managed at all.
The metaverse is, as they say, happening. Mark Zuckerberg announced last month that Facebook’s parent company, now called Meta, will take the lead in building out an immersive, interactive, and ubiquitous network of virtual environments that he envisions as the next phase of the Internet.
When Google introduced Manifest V3 in 2019, web extension developers were alarmed at the amount of functionality that would be taken away for features they provide users. Especially features like blocking trackers and providing secure connections.
In preventing people like me from accessing Twitter despite plainly qualifying under their own terms of service — and in failing to provide the kind of communication Dorsey testified under oath occurs in situations like mine — Twitter is arguably engaging in fraud, telling the public one thing while engaging in the opposite.
Privacy law is manifested in practice as a litany of “Agree” buttons to consent to data collection and a series of long, convoluted statements of data collection practices that are supposed to give users enough notice about what companies do with our data to enable us to make informed decisions.
It’s been 24 hours since Jack’s resignation, and while I’m not really interested in the evolving loser drama surrounding the new CEO’s decade-old tweets, it is worth noting that Twitter has already updated its content policy in a manner that effectively makes citizen journalism impossible.

It is refreshing to find instances in the IT sector where competing groups with their own agendas work together for the common good and the improvement of systems everywhere. So it is with the absorption of the Gen-Z Consortium by the CXL Consortium.
What is open core? Is a project open core, or is a business open core? That’s debatable. Like open source, some view it as a development model, others view it as a business model.
From the recent writeup of the DNS work at the IETF its clear that there is a large amount of attention being focused on the DNS. It’s not just an IETF conversation, or a DNS OARC conversation, but a conversation that involves a considerable amount of research activity as well.
It seems like Antarctica’s McMurdo Station could be getting high-speed internet—a modern day luxury feature that could connect its remote laboratories (and seasonal tourist hub) to the rest of the world. The station is located on an island just off the northwestern part of the continent and is the largest US research hub on Antarctica.

Rarely do cybercriminal gangs that deploy ransomware gain the initial access to the target themselves. More commonly, that access is purchased from a cybercriminal broker who specializes in acquiring remote access credentials — such as usernames and passwords needed to remotely connect to the target’s network.

If you’re looking for a rugged case for your phone or tablet, you’ve probably seen the terms MIL-SPEC or MIL-STD. But what do they mean? It’s a simple standard, but its appearance on product packaging is a complex topic.
Web 1.0 was from 1991 to 2004 when web users were consumers of content, and the web was a series of static websites. Web 2.0 emerged in 2004 as user-created content overtook static content. The big winners in this era have been the huge social media platforms that became some of the biggest companies on the planet.
Do-it-yourself is a great way to learn coding, but it’s a risky way to tackle complex application problems that have scant room for error, such as authentication and encryption.

Hedge 111: Machine Learning and Security with Micah Mussler
Machine Learning (ML) and Artificial Intelligence (AI) are all the rage in the network engineering world. Where might these technologies be useful, as opposed to mere hype? The two most obvious areas where AI and ML would be useful are failure reaction and security. Micah Mussler joins Tom Ammon and Russ White to discuss the possibilities of using AI and/or ML in the broader security market—and focusing in on the network.

DDR5 has barely hit the shelves, but Samsung has confirmed it’s already working on the next generation of RAM.
Speculative execution attacks present an enormous security threat, capable of reading arbitrary program data under malicious speculation, and later exfiltrating that data over microarchitectural covert channels. This paper proposes speculative taint tracking (STT), a high security and high performance hardware mechanism to block these attacks.
Alternatively, the unencrypted variants of these protocols can be upgraded to encrypted connections via a mechanism called STARTTLS.

Hedge 110: Andrew Alston and SRv6 Security
SRv6, a form of source routing, is the new and interesting method being created by the IETF to allow traffic engineering and traffic steering. This is not the first time the networking world has tried source routing, however—and in the spirit of rule 11, we should ask some questions. How and why did source routing fail last time? Have we learned those lessons and changed the way we’re doing things to overcome those limitations? Security seems to be one area where problems arise in the source routing paradigm.
Andrew Alston joins Tom Ammon and Russ White to discuss security in SRv6.
