TikTok's Footnotes is officially rolling out in the US for users in the pilot program. There are around 80,000 users contributing to TikTok's version of Community Notes - all of them have had active TikTok accounts for at least six months, live in the US, haven't had community guidelines violations in the past six months, and are at least 18 years old. Footnotes will be moderated with a combination of automated moderation and human moderation. Users can report footnotes they think are untrue or break TikTok's rules.
Tesla could be sunsetting the Model S and Model X as it has ended international orders. The two oldest cars in the company's lineup, the vehicles account for a very small portion of overall sales. Tesla doesn't make enough of the Model S or Model X units to justify the expensive logistics process of shipping custom orders overseas. It is possible the company may build a bunch of random configurations, send them overseas every few months, and let them sell before replenishing inventory.
Clinical trials for a drug that could eventually help people regrow missing or damaged teeth have begun in Japan. While humans typically grow two sets of teeth in their lifetime, the buds necessary to grow a third set still exist. The drug blocks a protein that limits tooth growth. The researchers hope to roll the drug out to the wider public by 2030.
Helion Energy has started site work on its commercial fusion power plant. The company's first facility is scheduled to start operating in 2028. It is building a 50 megawatt reactor to power Microsoft's data centers in the region. The entire tech sector is scrambling for new clean energy sources to power the servers that support artificial intelligence. Helion has spent 12 years on research and development and building prototypes in preparation for this deployment.
Fast software changes behavior. Fast eliminates cognitive friction and signals simplicity, which is rare in the world where code and content are commodities. Making software fast often requires stripping away non-essential features - the ultimate expression of respect in a world obsessed with adding rather than refining. It means the developer has thought deeply about what matters and eliminated everything else.
Choose novel technology when trying to learn something new and use boring technology when trying to solve a problem. Boring technologies have known failure modes, well-understood capabilities, and proven operational reliability. The advent of large language models and agent AI coding tools has made this principle even more critical. Developers who use technologies unknown to them have no way of verifying whether AI is leading them down the wrong path.
ChatGPT now seems to understand what it reads. The use of reasoning models shows that ChatGPT can be creative. It can summarize texts extremely well, a robust measure of intelligence. AI products now pay for AGI research, which means that AI has reached early stages of the long-awaited self-improvement loop.
Mark Zuckerberg says that the development of superintelligence is now in sight. He is extremely optimistic that superintelligence will help humans accelerate their pace of progress and begin a new era of personal empowerment where people will have greater agency to improve the world in the directions they choose. Meta's vision is to bring personal superintelligence to everyone to help them achieve goals, create what they want to see in the world, experience any adventure, and grow to become the person they aspire to be. It believes that the benefits of superintelligence should be shared with the world as broadly as possible.
The big hidden risk with automation through large language models is that it encourages mental disengagement, resulting in engineers overestimating agents' capabilities.
The single biggest cost for any metro system is the stations - a system that uses smaller trains would result in smaller stations and huge cost savings.
Vibe coding is perfect for prototypes and throwaway projects because the code doesn't have to be maintained - anything more serious needs a more careful approach.
A new iteration of SpaceX's Starship, V2, has been moved to Starbase in Texas for preflight testing. V3 is expected to launch by the end of this year.

Microsoft and OpenAI are in advanced talks over an agreement that would remove a major obstacle to OpenAI's efforts to become a for-profit enterprise. The new terms would let Microsoft use OpenAI's latest technology even if the startup decides it has reached its goal of building artificial general intelligence. The deal has still not been finalized and could change.
Startup Taara has a simple alternative to fiber-optic cables for crossing cities and tough terrain: free-space optical lasers. Its technology can reliably deliver 20-gigabit-per-second bandwidth across distances up to 20 kilometers. The company is planning to create a smaller version that can point, track, send, and receive signals at tens of gigabits per second indoors at 60 meters, as well as outdoors at 1 kilometer. Its biggest challenge is weather, but the technology will usually work as long as the other side is visible.
Apnimed achieved positive results for its first oral pill for treating sleep apnea in a Phase 3 clinical trial. The pill is taken just before bedtime to help keep a person's airway open. It could be a game-changer for those with sleep apnea - the current treatment involves putting on a face mask connected to a Continuous Positive Airway Pressure (CPAP) machine, which keeps airways open by forcing air into them. The machines are effective, but they are noisy and can be uncomfortable, so many end up abandoning them, leaving them feeling exhausted, irritable, and unfocused during the day.

Topics covered include cloud platforms, AI agents, large language models, AI tools, and job satisfaction.
Context engineering is the art and science of providing agents with just the right amount of information at each step of a task. It involves providing the right instructions, knowledge, and tools to optimize output while reducing token use. There are four common approaches to context engineering: writing context (saving it outside the context window to help an agent perform a task), selecting context (pulling it into the context window to help an agent perform a task), compressing context (retaining only the tokens required to perform a task), and isolating context (splitting it up to help an agent perform a task). Understanding and using these patterns is a central part of building effective agents.
A growing number of employers think that AI can do the work of a 22-year-old college graduate - some companies have stopped requesting entry-level staff. As companies hire and train fewer young people, they may also be shrinking the pool of workers that will be ready to take on more responsibility in five to 10 years. Companies will have to rethink how to develop the next generation of talent.
OpenAI is looking for a hardware systems product designer, a hardware system design electrical engineer, and a wireless/inductive charging electrical engineer.

The feature is currently free for any Mac or PC user with access to Copilot.
China's two biggest satellite internet networks have deployed less than 1% of their planned satellites. One of the reasons for this slow pace is China's lack of a reliable, reusable launcher. SpaceX's partly reusable Falcon 9 rocket has propelled the company far ahead of its competitors. While Starlink is intended for civilian use, it has become essential for communications in war zones.
A full-scale, piloted winged tilt-rotor eVTOL designed for commercial service flew from one airport to another for the first time ever earlier this month. Vertical Aerospace's vehicle flew 17 miles, during which it reached speeds of 115 miles per hour and an altitude of 1,800 feet. The prototype has a fixed-wing configuration with eight propellers. It was designed to accommodate one pilot and four passengers or cargo and travel a maximum range of 100 miles. Video of the flight is available in the article.
In this livestream, you'll learn why small, task-specific LLMs might outperform giant general-purpose models. JetBrains and Hugging Face introduce Mellum, an open-source model for code completion, and make the case for focal models that prioritize performance, sustainability, and accessibility.
Building effective AI agents is about system design and proper software engineering. Focus on clear instructions, lean context management, robust tool interfaces, and automated validation loops. Look for missing tools, unclear prompts, or insufficient context when debugging agents. Put error analysis first in the development process - let models help understand where the agent failed, then systematically address those failure modes. The goal isn't to create perfect agents but to make reliable and recoverable ones that fail gracefully and can be improved iteratively.
Google released a Linux Terminal app earlier this year, but only recently published documentation for it. The app is aimed at letting developers build Android apps directly on Android devices and will eventually allow users to run full-fledged graphical Linux apps and games. This could eventually transform Android into a first-class desktop platform that rivals macOS and Windows. The app currently doesn't support ARM-based CPUs.
Internet advertising gave us free content and services, and a mostly open Internet. That is now collapsing with the advent of AI. Content has now become training data for AI, unleashing a whole new wave of crawlers on the web that often offer nothing in return. AI companies repurpose the content they ingest and serve it directly to users without sending them to the original source, breaking the ad-based structure of the Internet. Content creators are rapidly fencing off their gardens, putting up paywalls and anti-bot measures so aggressive that users are having trouble accessing sites. Humans are retreating to more intimate corners of the web, naturally gravitating to spaces where real identity and authenticity are ensured.
The future will be increasingly augmented by AI. Designers need to be closer to the development of the technology to help shape the systems that will define how tomorrow's software is built. The industry needs builders who understand agentic flows, designers who can reason about trust boundaries and token windows, and researchers who can make complex systems usable without dumbing them down to a chat interface. Designers today have the tools to change the world with their ideas.
AI has evolved—from rule-based systems to generative models to agentic AI, where autonomous agents act with memory and context. But without orchestration, enterprises risk complexity, chaos, and failure to scale.

Japanese researchers used CRISPR-Cas9 to remove an extra copy of chromosome 21 from affected cells in a laboratory setting. The scientific milestone could reshape future approaches to treating Down syndrome. The CRISPR system targets the extra chromosome without affecting the normal pair. If the technique proves safe and reliable, it could be used in regenerative medicine.
Doctors at the Cleveland Clinic replaced heart valves through a small neck incision using robotic assistance, avoiding the need to open the chest. Four patients have so far undergone the procedure, called transcervical robotic access for aortic valve replacement, and were discharged within days, with one even resuming gym workouts just a week after surgery. The procedure is being performed exclusively at the Cleveland Clinic for now, but the team hopes to standardize it for use at other highly specialized centers. It could redefine what is possible for heart surgery.

Many studies seem to make GLP-1 therapies seem like holy water drawn from the fountain of youth, but the reality is that the final verdict on this medicine is still many years away. This article looks at whether GLP-1 drugs are really as good as they seem, how the drugs work, why they seem to be able to do everything, and whether everyone should be taking them. While the development of these drugs is exciting, the current side-effect profile isn't worth the risk for otherwise healthy patients.
Sean Goedecke wrote a post describing the kind of work he wanted in 2021 - this is a follow-up post on the type of work he wants now. Since 2021, the balance of power in tech has shifted away from engineers and towards tech companies. The biggest change in Goedecke's engineering values is that he no longer wants to work in a pure maintenance role on existing legacy systems. Overall, his 2021 and 2025 statements of values are fairly similar, despite changing a lot as an engineer over the years.

T-Mobile and SpaceX's T-Satellite service is now available to subscribers, allowing smartphone users to remain connected even in deadzones. Existing T-Mobile customers can purchase the cellular Starlink service as an add-on - those on pricier plans like Experience Beyond and Go5G Next get it as a free perk. People on other networks can also subscribe through a secondary eSIM. Those who participated in the free trial should now expect to be charged for the service.
Meta's wristband reads the electrical signals that pulse through the muscles when people move their fingers. It uses a technique called electromyography to gather electrical signals from muscles in the forearm. These signals can reveal what people are about to do even before they do it. With enough practice, people using the wristband can control devices simply by producing the right thought.
Neuralink expects to put its chips in 20,000 people a year and generate at least $1 billion in annual revenue by 2031. It plans to have about five large clinics in operation and at least three versions of its device available. The company's figures assume a conservative reimbursement of $50,000 per surgery. Several other brain companies are building and testing similar devices. No brain-computer interfaces have yet been commercially approved for permanent implantation by the US FDA - Neuralink expects to gain regulatory approval in the US for its first device by 2029.

Agent docs are a way to get better results from agents. They make agent output more consistent, more aligned with codebase conventions, and more accurate. This post discusses how to implement agent docs into a project. It covers how agent docs are different from internal eng docs, best practices for AI docs, and reasons why agent and eng docs should be kept separate.
One way to deal with aggressive web crawlers that don't respect robots.txt is to exhaust their resources. This post goes through how to build a valid HTML zip bomb that exhausts bots' RAM. The implementation technique exploits the asymmetry of the resources needed to serve the zip bomb versus those needed to detect it. Bots that respect robots.txt won't be affected by the zip bomb as the path to the zip bomb is forbidden in the specification.
