Power with purpose

In 2005, only 41% of Ghana’s population had access to electricity. Much of that electricity was generated by the Akosombo and Kpong dams on the Volta River, but relying on hydroelectric power made Ghana susceptible to climate fluctuations that affect water levels. Recalling how much his MIT thermodynamics class (then called Heat and Mass Transfer) with Ernest Cravalho had stayed with him, Asiamah-Adjei realized that perhaps delving into energy was not such a wild idea. “The seed had been sown,”

Prepare your wallets: Here’s when Samsung’s Android XR headset could be launching

Lanh Nguyen / Android Authority TL;DR Samsung’s long-awaited Project Moohan XR headset is reportedly launching on September 29 at the next Galaxy Unpacked event. The headset, possibly rebranded as the “Galaxy XR,” is powered by a Snapdragon XR2 Gen 2 SoC and 16 GB of RAM. Its rumored price is between $1,800 and $2,000, making it cheaper than the Apple Vision Pro. Samsung teamed up with Google for its Project Moohan headset on the brand-new Android XR platform. At the beginning of this year,

The Morning After: The most intriguing AI features inside the Pixel 10

After all the new Pixel 10 phones — expect to hear our review verdicts soon — we had time to take a closer look at the AI-centric software features Google often excels at. These include advances in Voice Translate, which can create a synthetic version of your voice speaking German. Or French. Or Japanese. Engadget There’s also Pro Res Zoom (Pixel 10 Pro devices only), which cranks zoom up to 100x, with AI guide rails to avoid twisted human faces and garbled text. In short, fewer AI hallucinati

ZDNET's key takeaways Although 95% of AI projects fail, research shows that successful initiatives focus on infrastructure. Top hurdles include poor integration, lack of skill sets, and difficulty building in-house AI solutions.

Paying attention to feature distribution alignment (pun intended)

Intro Yes, I’m making a joke of the tendency to put the words “attention” and “alignment” in any ML paper 😎. Now let’s see how this provocative title is related to our adventures in the land of polynomial features. The Legendre polynomial basis serverd us well in recent posts about polynomial features. One interesting thing we saw in the series is that its orthogonality is, in some sense informativeness. This is because it orthogonal bases produce features, and hence each basis function, in so

Teletext in North America

>>> 2025-08-25 teletext in north america (PDF) I have an ongoing fascination with "interactive TV": a series of efforts, starting in the 1990s and continuing today, to drag the humble living room television into the world of the computer. One of the big appeals of interactive TV was adoption, the average household had a TV long before the average household had a computer. So, it seems like interactive TV services should have proliferated before personal computers, at least following the logic t

Spotify launches a messaging feature in a bid to become more social

Spotify is introducing a way for you to chat with your friends in a bid to become a more social content consumption app. Users have shared Spotify links for music and podcasts with others outside the platform for years. With this feature, Spotify wants users to do more within the app while also keeping the history of shared content, so users don’t have to search for a song. Messages are only one-on-one, and you can only start a chat with someone with whom you have previously shared content. Th

Exploring the tragedy of the Counter-Strike 2 server browser

For those who enjoy Counter-Strike community servers, the situation in Counter-Strike 2 is rather dire. An avalanche of spam has rendered the server browser unusable. The transition from Global Offensive killed multiple small communities. And large server providers have taken advantage of these problems to monopolise the market. Trying to find a server either involves capitulating to these big vendors, or trawling through a trench of spam. Scraping the server browser allows us to have some in

Blacksky grew to millions of users without spending a dollar

If you haven’t been watching closely, you could be forgiven for assuming that Bluesky is a just liberal Twitter clone, or a newfangled imitator of Mastodon. But under the surface, something fascinating has been happening: this is the first time ever that a public benefit corporation with a small team has quickly scaled an open source social network, built on top of decentralized infrastructure, to tens of millions of users.

The Limits of NTP Accuracy on Linux

The Limits of NTP Accuracy on Linux Lately I’ve been trying to find (and understand) the limits of time syncing between Linux systems. How accurate can you get? What does it take to get that? And what things can easily add measurable amounts of time error? After most of a month (!), I’m starting to understand things. This is kind of a follow-on to a previous post, where I walked through my setup and goals, plus another post where I discussed time syncing in general. I’m trying to get the clock

a16z spends $1.49M in Washington lobbying, while rivals mostly sit out

Andreessen Horowitz’ plan to push its agenda in Washington shows no sign of slowing down, with the firm reporting $1.49 million in federal lobbying so far this year, according to lobbying records filed with Congress. A16z is even narrowly outspending its own industry trade group, the National Venture Capital Association. The pace of lobbying appears to be accelerating from last year, according to a TechCrunch review of lobbying disclosures. A16z spent $1.8 million on lobbying in all of 2024 and

Tesla could have avoided that $242.5M Autopilot verdict, filings show

Months before a jury awarded a $242.5 million verdict against Tesla over its culpability in a 2019 fatal crash, the automaker had a chance to settle for $60 million. Instead, Tesla rejected that offer, according to new legal filings that were first reported by Reuters. The settlement proposal, which was made in May, was disclosed in a filing that requested Tesla cover legal fees for the plaintiffs in the case. Earlier this month, a jury in federal court in Miami found Tesla partly to blame f

Imgur protest covers the front page in anti-MediaLab memes

Despite all the division and controversy rife in the modern era, sometimes the Internet does manage to collectively agree on something. Right now, they agree that they hate Imgur parent company MediaLab. After being acquired by MediaLab in 2021, the once famously open-to-anything image-sharing service began placing restrictions on content in 2023. More recently, the site has experienced service issues, including problems with notifications. Many members of the Imgur community have claimed that

Apple study shows LLMs also benefit from the oldest productivity trick in the book

In a new study co-authored by Apple researchers, an open-source large language model (LLM) saw big performance improvements after being told to check its own work by using one simple productivity trick. Here are the details. A bit of context After an LLM is trained, its quality is usually refined further through a post-training step known as reinforcement learning from human feedback (RLHF). With RLHF, every time a model gives an answer, human labelers can either give it a thumbs up, which re

The iPhone 17 event is likely in September: What to expect from Apple's upcoming launch

We're still waiting for Apple to make the official announcement for the iPhone event that usually takes place in September. At that event, they'll showcase the new iPhone 17 lineup which will come equipped with the latest iOS 26 features preinstalled, as well as any additional features Apple reveals at the launch event. But since we (presumably) still have to wait a few weeks until the iPhone event, we can only speculate what the new devices will look like. As with most unreleased iPhones, rumor

Overwatch 2 will overhaul its progression systems to show more visual flair in matches

The next season of Overwatch 2 will bring more than the usual new hero and battle pass to the team shooter. Blizzard announced that Season 18 will introduce a new take on the progression system.

New AI attack hides data-theft prompts in downscaled images

Researchers have developed a novel attack that steals user data by injecting malicious prompts in images processed by AI systems before delivering them to a large language model. The method relies on full-resolution images that carry instructions invisible to the human eye but become apparent when the image quality is lowered through resampling algorithms. Developed by Trail of Bits researchers Kikimora Morozova and Suha Sabi Hussain, the attack builds upon a theory presented in a 2020 USENIX

Perplexity's Comet AI Web Browser Had a Major Security Vulnerability

Comet, Perplexity's new AI-powered web browser, recently suffered from a significant security vulnerability, according to a blog post last week from Brave, a competing web browser company. The vulnerability has since been fixed, but it points to the challenges of incorporating large language models into web browsers. Unlike traditional web browsers, Comet has an AI assistant built in. This assistant can scan the page you're looking at, summarize its contents or perform tasks for you. The proble

An illustrated guide to OAuth

OAuth was first introduced in 2007. It was created at Twitter because Twitter wanted a way to allow third-party apps to post tweets on users' behalf. Take a second to imagine designing something like that today. How would you do it? One way would just be to ask the user for their username and password. So you create an unofficial Twitter client, and present the user a login screen that says "log in with Twitter". The user does so, but instead of logging into Twitter, they're actually sending the
