A programmer writes that Pratt parsing, often explained through a compact 9-line recursive function using binding powers, can be effectively applied without studying how the algorithm works internally. They cite building a Pratt-based parser for their own compiler project without first understanding the code's implementation details.
Apple's chief hardware officer Johny Srouji said the company uses AI algorithms during manufacturing to match each hinge to its housing and to 3D-print micro layers that smooth out imperfections in the foldable iPhone Duo. Despite this process, a number of the $2,000-plus device's inner screens are reportedly cracking near the hinge, with early assessments pointing to the hinge design as the likely cause.
Reddit announced a redesigned homepage with two feed options: 'For You,' which blends posts from joined communities with algorithmic recommendations, and 'Following,' which shows only subscribed communities. The company says the feeds are meant to boost discovery, connection and participation, and users can toggle between them with their last choice remembered on return visits.
An analysis argues that AI and social-media companies focus safety efforts on preventing high-profile disasters—the kind that trigger lawsuits or headlines—while ignoring subtler, widespread harms like emotional dependence on chatbots or engagement-driven feeds. It cites Google backing state-level chatbot bills in 2025 that banned sexual content and self-harm promotion but included broad exemptions, while tougher measures aimed at preventing emotional dependency failed, including in Nebraska.
An open format from the late nineties remains the only common way to read what you chose to read, in the order it was published, with nothing in between.
Australia is moving to enforce a law barring children under 16 from social media accounts, partly in response to accounts like Varsha Yajman's, who says platform algorithms pushed her toward pro-eating-disorder content as a teenager. Yajman, now 24 and recovering from anorexia, says she still receives weight-loss related content despite using strict safety settings and blocked keywords.
A developer's blog post explains a 'two-stack' method for computing sliding-window aggregations—such as minimum, maximum, or quantiles—that works even when the aggregation operator has no inverse. The technique, drawn from a paper by Tangwongsan et al. on low-latency sliding-window aggregation, achieves amortized constant-time updates using two stacks instead of a double-ended queue, and the author says it renders their own earlier six-year-old min/max algorithm obsolete.
YouTube announced updates to its Shorts recommendation system, aiming to favor original content over re-uploaded clips. Channels that mainly aggregate existing videos without adding new value are expected to see reduced visibility, encouraging creators to include commentary, edits, or storytelling. The platform has not specified whether this change will affect creators who clip their own longer videos for Shorts.
A hobby project called jevchat turns a model referred to as Jev into a chat interface by asking it, one symbol at a time, to predict the next character of its reply given the conversation so far. The tool samples from a probability distribution over a chosen alphabet (letters, truncated tokens, etc.) using configurable sampling strategies, displaying live generation stats and the top candidate symbols as it works. The creator built it with Claude's help by describing the sampling algorithms and having the AI implement them.
Agility Robotics has launched Digit 5, a general-purpose humanoid robot built with proprietary AI and sensor systems that detect nearby people and respond by moving aside, stopping, or dropping into a seated crouch. The behavior, shown in a promotional video, is powered partly by Nvidia's Thor IGX chip alongside vision sensors that continuously track human presence. Agility already deploys robots with companies like Amazon and Toyota and is positioning this safety-first design to broaden commercial adoption.
Google has released a new sorting algorithm that reimagines the classic Quicksort using vectorized, SIMD-based operations to speed up processing on modern CPUs. The project applies hardware-level parallelism to a decades-old algorithm, aiming to boost performance for large-scale sorting tasks.
Billionaire investor Mark Cuban argued in a series of X posts that public reaction to anti-AI content on social media is more dangerous than AI systems or agent swarms acting on their own. He claimed platforms like Meta and Google amplify anti-AI sentiment far more than positive coverage, even as those same companies profit from AI investment. Cuban said he isn't calling for a development pause, arguing it's not realistic anyway.
