"Billionaire Bill Ackman's life was upended this February when his 26-year-old daughter collapsed in her Brooklyn apartment, suffering a brain hemorrhage that would render her unable to move, speak or see," writes the Washingon Post. But then... The hedge fund manager did what any good father would do - at least, any father with vast financial resources and what friends describe as a "Mr. Fix-It" tendency. He sprung into action, getting her topline care at New York City's Mt. Sinai Hospital and consulting a network of well-connected friends all over the world. He helped her access a novel cell therapy that has been gaining traction among longevity enthusiasts, who are seeking ways to prolong human life. And then - motivated by a newfound desire to accelerate scientific research - he vowed to spend more than $400 million to launch an institute dedicated to longevity and brain health... He posted this week that the U.S. Food and Drug Administration, in May, gave his daughter Lucy's medical team a first-time emergency authorization to transplant mitochondria - the energy-producing part of human cells - from her leg muscle to her eyes, in the hopes that the tiny cell powerhouses would facilitate healing in her optic nerves and perhaps even restore her vision. Ackman's story highlights the increasingly prominent role of the ultra-wealthy in making expensive medical bets on longevity treatments and other novel therapies, altering the direction of research as federal funding for science declines in the second Trump administration. But his saga is a deeply personal one, spurred by his daughter's medical crisis. The focus on longevity by Ackman, who made billions on Wall Street as a hedge fund manager, is aligned with similarly ambitious efforts from some of Silicon Valley's biggest names. OpenAI CEO Sam Altman has backed Retro Biosciences, a start-up whose goal is to add 10 healthy years to the human lifespan through cellular reprogramming. Amazon founder Jeff Bezos is reportedly a funder of Altos Labs, which focuses on cellular rejuvenation and resilience... Billionaire investor Peter Thiel, Google co-founder Sergey Brin and Oracle co-founder Larry Ellison are also deeply invested in life-extension methods and attempts to rewrite the biology of aging... The therapy given to Ackman's daughter Lucy, known as mitochondrial transplantation, is of great interest not only to people who have suffered injuries, but to longevity-focused scientists who believe that mitochondria may hold promise for reversing some of the effects of aging... In recent years, scientists have discovered that mitochondria have many other functions beyond converting food into energy. They serve as clearinghouses for damaged cells, opening up the possibility that they can help with cell regeneration and healing, said Daria Mochly-Rosen, professor of chemical and systems biology at the Stanford University School of Medicine and co-author of " The Life Machines: How Taking Care of Your Mitochondria Can Transform Your Health." "I am one of those who believes that focusing on mitochondrial health is a way to address many human diseases, including aging itself," she said. "It's exciting."

A new article about AI in The Economist argues that "Initial effects of the technology on employment look positive." Perhaps AI will eventually make many humans unemployable - but there is no sign of it yet. On September 4th the Bureau of Labour Statistics reported that the American economy added 162,000 jobs in August, far above expectations. The unemployment rate is just 4.1%, lower than in almost 90% of months over the past half-century. Young workers, often cast as AI's first victims, are holding up remarkably well: the gap between unemployment among 20-24-year-olds and the overall rate is close to a multi-decade low. Some companies and workers are being severely disrupted by AI. Hiring in professional and business services is running about 10% below the average in 2015-19. Tech giants like Microsoft and Meta are trimming headcounts as they reorganise their businesses around the technology. Smaller firms such as Block, the owner of Square and Cash App, and Intuit, the maker of TurboTax and QuickBooks, are replacing people with bots. American companies have announced some 16,000 AI-related job cuts a month on average so far this year, according to Challenger, Gray & Christmas, an employment consultancy. But AI-related lay-offs gets lost in the churning jobs market where employers shed roughly 1.7m workers in a typical month. And the evidence so far is that AI is already creating a lot of jobs to replace those it has destroyed. The vast sums pouring into data centres and power generation have set off a race for construction and infrastructure workers. AI startups are hiring like there is no tomorrow. Incumbents racing to keep up are creating new AI roles. And by making some workers more productive, AI may be increasing demand for their services. Add it all up, and The Economist estimates that AI has so far created around 1m new jobs in America. That easily exceeds the roughly 200,000 lay-offs attributed to AI since mid-2023, and appears more than enough to offset weaker hiring in many back-office roles. Their article acknowledges that since January 2023 employment has fallen roughly 10% for customer-service workers and 15% for administrative assistants. But when The Economist looked at professions "closest to the AI boom" - engineers, software developers, mathematicians and data scientists - they found that since 2022 they've added roughly 730,000 jobs above trend. They see AI as creating new white-collar jobs for everyone from model and deployment engineers to new data annotators. The chief economist at the Burning Glass Institute agrees, estimating that roughly 1% of professional jobs are now "AI jobs" - about 1 million positions in the U.S. - while in computer occupations and life sciences it's between 4% and 5%. (Data-center construction spending also increased 60% in one year, according to Census Bureau data, creating jobs for electricians, HVAC specialists, grid engineers, and machine technicians.) And "Indeed finds that installation and maintenance jobs at data centres advertise wages about 40% higher than comparable work elsewhere."

Reuters reports: Liquid Network, a Bitcoin-based payments and settlement network, said on Sunday that about $320 million was withdrawn from its federation wallet in a hack. "Purported white-hat hackers" withdrew around 4,000 of the 4,200 bitcoin held in its Liquid Federation wallet, Liquid Network said in a post on X. "Liquid wallets will be impacted," their post concluded, adding "and we're sorry for any inconvenience."

Zenith is a variant of Windows for "developer-class devices". Project Zenith comes with a set of pre-installed tools spanning languages and runtimes, source control, and productivity tools. Windows Terminal and Visual Studio Code are pinned to the Taskbar by default, putting your favorite tools within immediate reach. We've also pre-configured Windows Settings for coding across File Explorer, Search, Start, and the Taskbar. File Explorer shows file extensions, hidden files, the full path in the title bar, and the details pane, with long-path support enabled. Recently used files and folders and sync provider tips are turned off for a cleaner workspace. In Search and Start, Command Palette is enabled, while Start menu tips and account notifications are turned off to reduce distractions. Windows Subsystem for Linux (WSL) has become foundational for running Linux workloads on Windows. Last year we open-sourced WSL. Building on that momentum at Build 2026, we integrated WSL more deeply into Windows with WSL containers to provide a built-in way to create, run, and interact with Linux containers directly on Windows. ↫ Logan Iyer at the Windows Blogs It's highly unlikely you'll be using this Zenith Windows flavour any time soon, as it requires 64GB of unified RAM with 250 GB/s memory bandwidth. In 2026, that's a serious ask. On top of that, it's not entirely clear to me if Zenith will be available as a separate Windows variant, without having to buy a complete device. Of course, it would be trivial to set all of this up on any fresh Windows installation.

We are pleased to announce the release of ReactOS 0.4.16! After a year and a half of development, we're excited to showcase the improvements we've made between a new graphical installer; a unified bootcd and livecd image; video, audio, networking, and storage stack improvements; a new installation type; and third-party code syncs. ↫ The ReactOS Team on the ReactOS website The amount of changes and improvements is quite staggering, honestly. They'll always be chasing a moving target, sure, but if they manage to keep this rate up ReactOS might actually grow into something usable in its own right, full compatibility with Windows or not. Excellent progress.

Virtually all laptop speakers suck. It's the one area where even really expensive laptops tend to fall on their ass, leaving users with a tinny, harsh, and hollow sound experience. While you can't exactly overcome physics - laptop speakers are necessarily small and thus just cannot ever sound as good as proper speakers - there's a lot you can do with proper tuning and software magic. If you're a desktop Linux user, you actually already possess all the plumbing needed to fix your audio; it's just not exposed to you in any way. Luckily, an application called EasyEffects allows you to actually make use of desktop Linux' advanced audio features to massively improve the sound quality of your laptop's speakers. EasyEffects' own description on its GitHub page doesn't really explain what it does or what it's capable of, so here's the description from Wikipedia instead. EasyEffects uses PipeWire to process incoming and outgoing audio streams independently and can apply various sound effects in the form of plug-ins made by different developer teams such as Calf Studio Gear, MDA.LV2 and GStreamer. All plugins have their own presets and can be applicable inside the suite rather than having to use a different mixer or executing a script from the command line. Available output effects are limiter, auto volume, compressor of dynamic range, filter, 30 bands parametric equalizer, bass enhancer, exciter, reverbation, crossfeed, delay, maximizer and spectrum analyzer. Available input effects are WebRTC, limiter, compressor, filter, equalizer, de-esser, reverbation, pitch shift and spectrum analyzer. ↫ EasEffects' Wikipedia page None of this matters, and you can forget everything from these two paragraphs. What matters is that using EasyEffects, you can tune the audio coming out of your speakers to make them sound a lot better. The few laptops on the market that do have decent audio - MacBooks, some Dell XPS laptops, and surely a few more - aren't magically defying physics. While they probably do have objectively higher-quality speakers, the main difference between those laptops and laptops with crappy-sounding speakers is that the former come with built-in tuning from the factory to make them sound much better than they would without any software trickery. If you know your way around audio, you can very much use EasyEffects and tune your laptop speakers from scratch to massively improve how they sound. However, that requires time, experience, knowledge, and expertise that most people lack, including myself. Lucky for us, though, there are countless downloadable presets out there for EasyEffects designed specifically to make laptops sound better. In an ideal world, you'd pick a preset created specifically for your laptop make and model, but odds are you won't find one, so for most laptops you'll have to settle for a generic preset that tries to do its best. I've long settled on the Advanced Auto Gain.json preset from JackHack96, which greatly improves the audio performance on any laptops I've tried it on, but of course, there's countless other presets for you to try to see if there's anything that suits your particular laptop and ears better. Getting all of this up and running is really easy. EasyEffects is most likely packaged by your Linux distribution, and the latest version is always available as a Flatpak from Flathub. Download the preset(s) you want to try, copy them either to ~/.config/easyeffects (if you use your distribution's package) or to ~/.var/app/com.github.wwmm.easyeffects/data/easyeffects/output/ (if you use the Flatpak version). They'll show up right away in the Presets tab in EasyEffects, ready to be turned on and off whenever you want, making it very easy to compare and contrast to find the one you like best. EasyEffects can live in your system tray giving you easy access to your presets without having to open the main window, and it can be set to start automatically at boot. EasyEffects can also be turned on and off on the fly. There's obvious downsides to all of this, too, of course. First, since you're most likely going to be using a generic preset not specifically crafted for your laptop, there's no guarantee the results will be positive for you. Second, not every preset is ideal for every type of audio. Most of my audio consists of YouTube videos with mostly speech; if you listen mostly to music, different presets may yield better results. Third, audio quality is deeply subjective, and what sounds good to my ears may sound like total garbage to yours. Fourth, EasyEffects does take up a tiny fraction of CPU power (I'm talking 0.1-0.2% according to KDE's System Monitor), but I have never seen it have any noticeable performance impact on anything. Even the generic preset I use makes such a massive difference for me on every laptop I've ever tried it on, that I've become convinced EasyEffects and a few of the generic presets should be installed by default by any desktop-oriented Linux distribution. On top of that, Linux laptops OEMs like System76, Nova Custom, Star Labs, and so on, should really take the time to create proper presets for their laptops to improve their sound quality out of the box. I feel like if you're already designing and selling laptops, you probably also have the skills and means to create a decent preset. In fact, I'd take it a step further and urge desktop environments like KDE and GNOME to properly integrate EasyEffects into their sound settings. They shouldn't include the entire application and its user interface, but should make it so that you can configure and manage presets right from the sound settings panels, and switch between presets from their volume applets (as well as turn it off entirely, of course). This would leave the full EasyEffects application for people who need more control, manual tuning, and more advanced features. There's absolutely no reason why speakers on Linux laptops should sound tinny, harsh, and hollow. The Linux desktop has all the technologies and features built right in to make speakers sound much better than they do without any tuning,

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.

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.
