Learn Your Way: Reimagining Textbooks with Generative AI

Grounded in learning, built for the student Our approach is built on two key pillars that work together to augment the learning experience: (1) generating various multimodal representations of the content, and (2) taking foundational steps toward personalization. The seminal dual coding theory states that forging mental connections between different representations strengthens the underlying conceptual schema in our brain. Subsequent research indeed showed that when students actively engage wi

Amazon Music launches AI-powered weekly playlists based on 'preferences and mood'

Amazon Music has just launched new AI-powered weekly playlists based on the "preferences and mood" of listeners. This just means it scrapes what you've already been listening to and extrapolates further. It doesn't apply modern technology to gauge the actual mood of users. The company says the playlists include "a curated mix of familiar favorites from their most listened-to artists and latest favorites to new discoveries." I'm not exactly sure how this is different from what music streaming pl

Blogs used to be different

Blogs used to be very different. 06 Sep, 2025 I saw someone earlier post about how intrusive it felt to read a personal blog post. They made a point that folks like them who have grown up on short form microblogging like Twitter and Tumblr have a big leap to make when reading longer form blogposts. Not sure how many folks have that same issue but from the blogs I've read in the last decade, there has been a huge shift in content. Ten years ago if you were blogging on Tumblr or Wordpress you w

SQL needed structure

Published 2025-09-04 Here are two pages from the internet movie database: There are two things to note about these pages. The data on the page is presented in a hierarchichal structure. The movie page contains a director, a list of genres, a list of actors, and each actor in the list contains a list of characters they played in the movie. You can't sensibly fit all of this into a single flat structure like a relation. The order of the hierarchy isn't the same on both pages. On one page we hav

Microsoft gives US students a free year of Microsoft 365 Personal

Microsoft announced that starting this Thursday, all college students in the United States can get a free year of Microsoft 365 Personal. For everyone else, a yearly Microsoft 365 Personal subscription costs $99.99. It provides ransomware protection for photos and files stored on OneDrive, 1 TB of secure cloud storage, and can be used on up to five devices simultaneously. As Microsoft President Brad Smith also revealed yesterday, students who claim their free subscription can also receive a 50

OpenAI boosts size of secondary share sale to $10.3 billion

OpenAI is increasing the size of its secondary share sale by more than $4 billion, CNBC has learned. The artificial intelligence startup is giving eligible current and former employees the opportunity to sell roughly $10.3 billion in stock, up from the $6 billion it was initially targeting, according to a person familiar with the offering. The sale will be at a $500 billion valuation, in line with expectations, said the person, who asked not to be named because the details are private. OpenAI'

European court rules in favor of the latest US and EU data transfer framework

Europe’s second-highest court has dismissed a challenge against a data transfer pact between the European Union and the US. "On the date of adoption of the contested decision, the United States of America ensured an adequate level of protection for personal data transferred from the European Union to organisations in that country," the EU’s General Court ruled ( PDF ). The two sides brokered the Trans-Atlantic Data Privacy Framework in 2023 to continue allowing US companies to store European us

The CDC’s New Acting Director Is a Peter Thiel Pal (and a Total Nightmare)

As America's pivotal health agency descends into chaos, the White House has selected the worst possible person to run it. The Center for Disease Control and Prevention is in chaotic disarray, as a slew of resignations and an unprecedented walkout of staff have roiled the agency. At the center of the controversy is the CDC’s weirdo director, Robert F. Kennedy Jr., whose most recent contribution to public health dialogue was a bizarre rant about what passes through his mind as he stares at childr

In Search of AI Psychosis

AI psychosis (NYT, PsychologyToday) is an apparent phenomenon where people go crazy after talking to chatbots too much. There are some high-profile anecdotes, but still many unanswered questions. For example, how common is it really? Are the chatbots really driving people crazy, or just catching the attention of people who were crazy already? Isn’t psychosis supposed to be a biological disease? Wouldn’t that make chatbot-induced psychosis the same kind of category error as chatbot-induced diabet

Petition to stop Google from restricting sideloading and FOSS apps

As Google will allow only apps from verified developers to be installed on Android (previous discussion): https://news.ycombinator.com/item?id=45017028 A developer started a petition to stop Google from limiting app installation on Android devices unless developers provide personal identity documents. Even though Google has not revoked similar controversial policies in the past, we do our best as much as we can. This change particularly threatens the freedom to build, share, and use software w

TransUnion says hackers stole 4.4 million customers’ personal information

Credit reporting giant TransUnion has disclosed a data breach affecting more than 4.4 million customers’ personal information. In a filing with Maine’s attorney general’s office on Thursday, TransUnion attributed the July 28 breach to unauthorized access of a third-party application storing customers’ personal data for its U.S. consumer support operations. TransUnion claimed “no credit information was accessed,” but provided no immediate evidence for its claim. The data breach notice did not s

Open Source is one person

The Register recently published a story titled Putin on the code: DoD reportedly relies on utility written by Russian dev. They should be ashamed of this story. This poor open source developer is getting beat up now to score some internet points. It’s very upsetting. But anyway, let’s look at some receipts. If you’re not real smrt, it seems like pointing out an open source project is written by one person in a country you don’t like is a bad thing. It could be. But it also could be the softwar

The personhood trap: How AI fakes human personality

Recently, a woman slowed down a line at the post office, waving her phone at the clerk. ChatGPT told her there's a "price match promise" on the USPS website. No such promise exists. But she trusted what the AI "knows" more than the postal worker—as if she'd consulted an oracle rather than a statistical text generator accommodating her wishes. This scene reveals a fundamental misunderstanding about AI chatbots. There is nothing inherently special, authoritative, or accurate about AI-generated ou

Why Aren't People Going to Local and Regional In-Person Events Anymore?

Steve Jones recently posted an update about SQL Saturday’s status, and it includes some news we need to talk about: However, this year the number may stagnate or even decline slightly. Running events has become challenging for many communities. Organizers are busy, space is hard to find, and costs are rising…. The biggest challenge in running events is finding space at a reasonable cost. Many Microsoft offices are closing, which were strong supporters of events in the past. Steve gives a coupl

Chinese ‘Virtual Human’ Salespeople Are Outperforming Their Real Human Counterparts

The salesperson hawking Brother printers on Taobao works hard—like, really hard. At any time of the day, even when there’s no audience on the Chinese ecommerce platform, the same woman wearing a white shirt and black skirt is always livestreaming, boasting about the various features of different office printers. She has a phone in one hand and often checks it as if to read a sales script or monitor the viewer comments coming in. “My friends, I’ve gotta plug this game-changing office tool that c

Incan numerical recordkeeping system may have been widely used

Inca bureaucrats recorded all the goings-on in their bustling empire using knotted cords called khipu, where the position and order of the knots represented numbers. They relied on the khipu system to track people, taxes, produce, livestock, and products like woven cloth and beer. Because khipu were so vital to the Inca government, and because the khipu itself is such a sophisticated way of recording numbers, colonial writers decided that these tools must be the exclusive knowledge of a very sp

Ask HN: How do you tune your personality to get better at interviews?

I just got declined for a job and it has gotten under my skin much more than it should. (Under the advisement of my lawyer (ChatGPT) I won't say the company's name). It has really annoyed me; I ended up doing three interviews over the course of four weeks, and I'm pretty confident that I got the technical questions right. It could be that my resume is too "jumpy", which is fair, but they could have read my resume before they wasted my time and theirs with three multi-hour interviews. The only

Let's get real about the one-person billion dollar company

If you like this post, follow my journey on Twitter: https://x.com/random The biggest hurdle to the one-person billion dollar company is not AI capability, but founder pain tolerance. Sam Altman is betting on it in his private group chats. Dario Amodei predicted it'll happen in 2026. These geniuses think the one-person billion dollar company is inevitable, and unicorn teams are getting smaller, but a one person? That’s not going to just happen. One person is an intentional choice by an i

Subscribe Now A new study from the Anthropic Fellows Program reveals a technique to identify, monitor and control character traits in large language models (LLMs). The findings show that models can develop undesirable personalities (e.g., becoming malicious, excessively agreeable, or prone to making things up) either in response to user prompts or as an

Funeral Homes Are Using ChatGPT to Churn Out Lazy Obituaries

Funeral companies and grieving families are turning to AI chatbots to cough up obituaries for the recently deceased, the Washington Post reports, in yet another example of how the tech is being used to automate even the most emotionally charged parts of the human experience. One bellwether of the AI's rise in the death care industry was last year's National Funeral Directors Association conference in Las Vegas, where it was apparently the talk of the town, according to Ryan Lynch, head of produ

Anthropic wants to stop AI models from turning evil - here's how

Lyudmila Lucienne/Getty ZDNET's key takeaways New research from Anthropic identifies model characteristics, called persona vectors. This helps catch bad behavior without impacting performance. Still, developers don't know enough about why models hallucinate and behave in evil ways. Why do models hallucinate, make violent suggestions, or overly agree with users? Generally, researchers don't really know. But Anthropic just found new insights that could help stop this behavior before it happen

Persona vectors: Monitoring and controlling character traits in language models

Language models are strange beasts. In many ways they appear to have human-like “personalities” and “moods,” but these traits are highly fluid and liable to change unexpectedly. Sometimes these changes are dramatic. In 2023, Microsoft's Bing chatbot famously adopted an alter-ego called "Sydney,” which declared love for users and made threats of blackmail. More recently, xAI’s Grok chatbot would for a brief period sometimes identify as “MechaHitler” and make antisemitic comments. Other personali

Delta denies using AI to come up with inflated, personalized prices

Delta spent July dealing with backlash over what the airline company claims is widespread public confusion over its AI pricing system. Now, Delta has finally come forward to break down precisely how the AI pricing works to dispute what it claims are "incorrect" characterizations by consumer watchdogs, lawmakers, and media outlets. In a letter to lawmakers who accused Delta of using AI to spy on customers' personal data in order to "jack up" prices, Delta insisted that "there is no fare product
