Why Are Big Tech CEOs Writing Long Manifestos About AI?

This week Meta CEO Mark Zuckerberg published a 6,500 word open letter titled "The Future is for Everyone". But the BBC is more interested in why big tech executives keep writing manifestos about AI: [Zuckerberg's] vision echoes what AI leaders have expressed in various forms: the product they are building is among the "most important technologies in history." Marc Andreessen, co-founder of early web titan Netscape, perhaps started this trend in 2023 with a 5,000-word essay he called "The Techno-Optimist Manifesto", which argued innovation was the way to solve life's problems... As the International Monetary Fund warns AI could affect nearly 40% of jobs and worsen global financial inequality, Zuckerberg says he believes there will be an abundance of jobs in the future. "I do not understand why anyone who believes that AI will eliminate most jobs and much of humanity's relevance would rush to build that future." Never mind that Zuckerberg's Meta has cut 10% of its global workforce - about 8,000 jobs - as the company reorganizes to focus on AI. Zuckerberg's manifesto is the latest to land in our social media feeds in an effort to put a positive spin on AI. In 2024, ChatGPT-maker OpenAI boss Sam Altman released a manifesto called "The Intelligence Age", a sweeping expression of optimism about the tech's potential... That same year, in a manifesto titled "Machines of Loving Grace", Anthropic CEO Dario Amodei touted the potential of AI to transform everything from healthcare to politics. So what's going on with these tech executives' manifestos? Economics blogger Noah Smith suggested to the BBC "they all feel like it's such an important moment that it's incumbent upon them to do whatever they can to shape the direction that this technology is going." Although he does see some value in their engagement with important issues. "Should we open-source something that has the ability to kill humanity? If you don't take that seriously, you're just a fool." But Rob Lalka, a business professor at Tulane University, had a different explanation for the BBC: Lalka said the timing of Zuckerberg's manifesto coincides with rising anger over AI's impact on everything from jobs to the environment. And while tech journalists and academics might pore over them trying to glean nuggets of meaning, these executive manifestos are not necessarily landing with the general public. "They're trying to make the case that the positives will far outweigh some of those negatives that the public backlash is pointing out," he said. "But I think a lot of the reasons for optimism are still yet to be seen."

Vulnerability Giving Attackers Full Control of Macs Is Under Active Exploitation

joshuark shares a report from Ars Technica: Dutch officials have warned that a high-severity macOS vulnerability that allows attackers to execute malicious code is under active exploitation. "The NCSC has received a notification indicating that active abuse of this vulnerability has been observed on multiple systems on which port 5900 was accessible from the Internet," the Netherlands National Cyber Security Centrum warned earlier this week. "In all these cases, root had been accessed on the affected system and a Monero crypto miner had been placed." The vulnerability, tracked as CVE-2026-65400, received a patch from Apple last week for macOS Tahoe, Sequoia, and Sonoma. The vulnerability, with a severity rating of 7.1 out of 10, stems from a bug in the macOS screen sharing capability, which allows a remote party to view the screen and control the keyboard and mouse while a machine is turned on. A flaw in the "state management," which keeps track of preceding events, user interactions, variables, and other system states, is the underlying cause. A video of the exploit in action can be found here. Details of CVE-2026-65400 became public at last week's Black Hat security conference. Apple said last week that CVE-2026-65400 "may" allow an attacker without credentials to gain access to a Mac. It's unclear why Apple hedged, but softening language is common among most tech developers when disclosing vulnerabilities. As noted by the NCSC, the vulnerability is being exploited when port 5900 is exposed to the Internet. When screen sharing is turned on, the macOS firewall opens the port. Routers and dedicated firewalls generally block the port unless configured to override that setting. Security practitioners generally advise Mac users to keep the port closed even when using screen sharing and to instead connect over a VPN or through SSH tunneling. The alternatives require actions that aren't within the capabilities of most users. The safest practice is to block screen sharing, enable it only when screen sharing is needed, and to turn the feature off once a session has ended. Screen sharing can be turned on or off by accessing System Settings > General > Sharing and toggling the switch for Screen Sharing. Of course, installing last week's security update is also a must. Sharing is not caring.

Astronomers Discover a New Kind of Cosmic Object: a Black Hole 'Star'

Astronomers using the James Webb Space Telescope say they may have found a new class of object: a "black hole star," in which a black hole is wrapped in dense gas and radiates in ways that resemble an enormous star. The Guardian reports: The international team made the breakthrough after focusing their attention on a mysterious red spot in images of the early universe captured by Nasa's James Webb space telescope. The object was lurking in the constellation of Cetus, the Whale, billions of light years from Earth. It is thought to have formed 660m years after the big bang, astronomers' leading theory as to how the universe began. Measurements of the exotic body found that while it resembles an immense star, it releases 100bn times more energy than any known star can produce. The energy output is far closer to that observed from black holes than stars. The findings have been published in the journal Nature.

The worst PDA of all time

Today, you can get low-quality knockoffs of just about any popular smartphone on sites like AliExpress or Temu, whether they be iPhones, Galaxy phones, or whatever else. They have terrible build quality, bottom-of-the-barrel components and specifications, and all run outdated versions of Android - badly. At the same time, various consumer electronics brands, once popular in a bygone era, sell the rights to their brand name to unknown companies, who then put these brands on generic hardware to give their products a sheen of legitimacy. That's why today, you can still buy Nokia smartphones, Polaroid cameras, and low-effort Hi-Fi equipment from various once-respected brands. None of this is new, however. In the late '90s and early 2000s, companies were already doing the same thing. In fact, there's one device from this era which combines both business practices - it's both a cheap knockoff of a wildly successful device, and it carries a once-revered brand name. Also, just to add some juice, this story involves stolen source code. Let's take a look at the worst PDA of all time, the Olivetti daVinci. In 1997, Palm launched the Palm Pilot, and it and its successors proved to be a massive hit. Where countless before it had failed, Palm found the magic formula to make pocket computing work. I wrote an in-depth article about Palm over 13 years ago which goes into much (much) more detail, but the reason the Palm Pilot succeeded where things like the Newton, PenPoint OS, and Windows for Pen Computing failed, is that Palm's founder, Jeff Hawkins, realised that they were competing with paper, not with desktop computers. Instead of trying to shove the capabilities of a full personal computer into a (barely) pockatable device, a pocket computer had to be as fast and convenient as paper, and therefore extremely strict about which features to add, and which to omit. To this day, the entirety of smartphone computing stands on the shoulders of Palm. Palm's ideas, implementations, approaches, paradigms, and even people were absorbed by Apple and Google, where they shaped both iOS and Android. The phone you're looking at right now has a ton of Palm DNA in it, still. After all, you're still using the homescreen-with-apps paradigm Palm already perfected in the late '90s and early 2000s. The success of the Palm Pilot and its successors did not go unnoticed. Microsoft, most prominently, felt incredibly threatened by Palm's success: The success of Palm's products got the attention of Microsoft, and the company pretty much announced it was going to crush Palm. According to Hawkins, Microsoft had a sales conference, where, at some point, a big target appeared on the projector screen, with the Palm logo dead in the centre of it: "we are going to crush and kill these guys", was the central message. Hawkins recalls that he got condolence letters after that, stating things like "Sorry Jeff. Too bad." ↫ Thom Holwerda While Microsoft proved to be unable to "kill and crush" Palm, it did manage to build a relatively successful business selling PDAs running various incarnations of Windows CE. Together, Palm and Microsoft dominated the PDA market pretty much throughout its entire existence, and while the market was a mere fraction of the smartphone market of today, other companies still wanted a piece of this pie too. One of these companies was Olivetti, a storied Italian company with a long history making typewriters, computers, and other electronics. I'm not going into detail about Olivetti's history, but the company was renowned for its attention to design, creating iconic products like the Lexikon 80, Lettera 22, Elea 9003, Programma 101, and so, so many more. Olivetti also entered the personal computer market, first with a variety of custom machines featuring Z80 and later Motorola 68000 processors running a variety of custom operating systems developed by Olivetti (including its own UNIX variant, X/OS). After a few machines using MIPS and Alpha processors in the early '90s, the company would eventually focus entirely on Intel-based PCs (including this amazing failure) running Windows. Like so many other computer makers from that era, Olivetti eventually left the PC business by selling it off in 1997. To this day, Olivetti PCs tend to cost more on the used market than those from other brands, despite no technical merits dictating so. At around this time, our current story begins. Seeing the success of the Palm Pilot and the emergence of copycat devices running Microsoft's Windows CE, Olivetti wanted in on the action. And so, in the late '90s, the company introduced the Olivetti daVinci, a line of PDAs whose software looked suspiciously like Palm OS. There's not a ton of information out there about the development history, but it seems that while Olivetti designed the hardware, it contracted the development of the operating system out to a company from Hong Kong, Echolink Design. And this is where things went horribly wrong for Olivetti. The software Echolink Design developed for the daVinci didn't just look like Palm OS, it was Palm OS - at least, according to Palm. After being on the market for about a year, the Palm Pilot maker, then a subsidiary of 3Com, filed for an injunction, alleging that the daVinci operating system designed by Echolink Design contained actual Palm OS source code. In addition, Palm also filed suit against CompanionLink Software, the company that developed the Outlook synchronisation software for the daVinci. Palm won handily, and within a day of the filing, temporary restraining orders were put in place on both Olivetti and CompanionLink, stopping sales of the daVinci and its software dead in its tracks. It seemed to have been a pretty clear-cut case. From The Wall Street Journal at the time: U.S. District Judge James Ware ruled Olivetti's Royal daVinci organizer contains software that appears to have been copied from the operating system for 3Com's Palm organizers. Judge Ware said a review by a software expert found the daVinci software contains private Palm code and even grammatical

Making a game on a custom bytecode VM in 7 days and 3kB

In the last few days, I built a shoot 'em up game by embedding a tiny custom bytecode VM and rendering the graphics using a fullscreen pixel shader. The result is a 3kB Windows executable. This was done for Langjam Gamejam, a 7-day challenge where you create a programming language and then use it to build a game. The project combines several interests of mine: language tooling, game development, procedural graphics, and demoscene-style size constraints. The game jam format forced me to keep the scope small and explore new ideas. Also, it was fun! ↫ Laurent Le Brun In seven days, Le Brun created a brand new programming language, compiler, bytecode interpreter, a game written in the new language, and rendered it, ending up with a 3kB self-contained executable. It's amazing what humans can do.

Why tiny JPEGs look different in Chrome

A while back, when chatting with a colleague over their computer, I noticed that a logo did not look exactly the same as it did on mine. It looked thinner on theirs and more faithful to the original image. It was rendered at 15px; here is an upscaled version. If you squint, or take a step back, the one from Chrome looks thicker. A bit weird, but swapping the image for an SVG fixed it. Still, I was curious: why was it rendering like this in the first place? I did some digging and found a nifty optimization that Chrome uses when rendering JPEGs at small scales. ↫ Guillaume Técher I love it when people detail their discoveries like this.

On scripts and hooks

Over the last few weeks, we have been doing research on the integration of our official distribution packages when installed on a target system. In this context we have been looking at the current uses of alpm-install-scriptlet(5) files and alpm-hooks(5) in around 120 package source repositories (alpm-source-repo(7)) to better understand the underlying functionality and use-cases these two integrations offer and target. In this article we are going to look at how these two systems work, how Arch Linux is currently using them and attempt to provide suggestions for when to use which.

Resigning from Arch Linux

This is just a short note on my blog that I have resigned from Arch Linux a package maintainer, developer and security team. I've spent around 10 years as an AUR maintainer, security team, Package Maintainer and then Developer. I implemented support for debug packages, did the initial POC work that would become the git migration and even somehow managed to pull of an online conference during The Plague with the help of others.
