Jack Dorsey Says His 'Secure' New Bitchat App Has Not Been Tested For Security (techcrunch.com) 37

An anonymous reader quotes a report from TechCrunch: On Sunday, Block CEO and Twitter co-founder Jack Dorsey launched an open source chat app called Bitchat, promising to deliver "secure" and "private" messaging without a centralized infrastructure. The app relies on Bluetooth and end-to-end encryption, unlike traditional messaging apps that rely on the internet. By being decentralized, Bitchat has potential for being a secure app in high-risk environments where the internet is monitored or inaccessible. According to Dorsey's white paper detailing the app's protocols and privacy mechanisms, Bitchat's system design "prioritizes" security.

But the claims that the app is secure, however, are already facing scrutiny by security researchers, given that the app and its code have not been reviewed or tested for security issues at all -- by Dorsey's own admission. Since launching, Dorsey has added a warning to Bitchat's GitHub page: "This software has not received external security review and may contain vulnerabilities and does not necessarily meet its stated security goals. Do not use it for production use, and do not rely on its security whatsoever until it has been reviewed." This warning now also appears on Bitchat's main GitHub project page but was not there at the time the app debuted.

As of Wednesday, Dorsey added: "Work in progress," next to the warning on GitHub. This latest disclaimer came after security researcher Alex Radocea found that it's possible to impersonate someone else and trick a person's contacts into thinking they are talking to the legitimate contact, as the researcher explained in a blog post. Radocea wrote that Bitchat has a "broken identity authentication/verification" system that allows an attacker to intercept someone's "identity key" and "peer id pair" -- essentially a digital handshake that is supposed to establish a trusted connection between two people using the app. Bitchat calls these "Favorite" contacts and marks them with a star icon. The goal of this feature is to allow two Bitchat users to interact, knowing that they are talking to the same person they talked to before.

Browser Extensions Turn Nearly 1 Million Browsers Into Website-Scraping Bots (arstechnica.com) 28

Over 240 browser extensions with nearly a million total installs have been covertly turning users' browsers into web-scraping bots. "The extensions serve a wide range of purposes, including managing bookmarks and clipboards, boosting speaker volumes, and generating random numbers," reports Ars Technica. "The common thread among all of them: They incorporate MellowTel-js, an open source JavaScript library that allows developers to monetize their extensions." Ars Technica reports: Some of the data swept up in the collection free-for-all included surveillance videos hosted on Nest, tax returns, billing invoices, business documents, and presentation slides posted to, or hosted on, Microsoft OneDrive and Intuit.com, vehicle identification numbers of recently bought automobiles along with the names and addresses of the buyers, patient names and the doctors they saw, travel itineraries hosted on Priceline, Booking.com, and airline websites, Facebook Messenger attachments and Facebook photos, even when the photos were set to be private. The dragnet also collected proprietary information belonging to Tesla, Blue Origin, Amgen, Merck, Pfizer, Roche, and dozens of other companies.

Tuckner said in an email Wednesday that the most recent status of the affected extensions is:

- Of 45 known Chrome extensions, 12 are now inactive. Some of the extensions were removed for malware explicitly. Others have removed the library.
- Of 129 Edge extensions incorporating the library, eight are now inactive.
- Of 71 affected Firefox extensions, two are now inactive.

Some of the inactive extensions were removed for malware explicitly. Others have removed the library in more recent updates. A complete list of extensions found by Tuckner is here.

UK Full-Fiber Broadband Coverage Jumps From 12% to 78% in Five Years (ft.com) 28

The UK has transformed its broadband infrastructure in five years -- with full-fiber coverage jumping from 12% of properties in January 2020 to more than 78% by 2025, according to communications regulator Ofcom and ThinkBroadband data. Northern Ireland leads with 96% of premises in postcodes served with full-fiber connections.

The rollout accelerated after Ofcom's May 2021 regulatory framework gave other providers access to BT's Openreach ducts and poles while promising the company regulatory certainty through a "fair bet" approach that avoided price caps. The framework sparked investment from alternative networks, or "altnets," which increased homes passed from 8.2 million in 2022 to 16.4 million by 2025.

OpenAI To Release AI Web Browser in Challenge To Chrome (reuters.com) 58

OpenAI is close to releasing an AI-powered web browser that will challenge market-dominating Google Chrome, Reuters reported Wednesday. From the report: The browser is slated to launch in the coming weeks, three of the people said, and aims to use artificial intelligence to fundamentally change how consumers browse the web. It will give OpenAI more direct access to a cornerstone of Google's success: user data.

The Open-Source Software Saving the Internet From AI Bot Scrapers (404media.co) 33

An anonymous reader quotes a report from 404 Media: For someone who says she is fighting AI bot scrapers just in her free time, Xe Iaso seems to be putting up an impressive fight. Since she launched it in January, Anubis, a "program is designed to help protect the small internet from the endless storm of requests that flood in from AI companies," has been downloaded nearly 200,000 times, and is being used by notable organizations including GNOME, the popular open-source desktop environment for Linux, FFmpeg, the open-source software project for handling video and other media, and UNESCO, the United Nations organization for educations, science, and culture. [...]

"Anubis is an uncaptcha," Iaso explains on her site. "It uses features of your browser to automate a lot of the work that a CAPTCHA would, and right now the main implementation is by having it run a bunch of cryptographic math with JavaScript to prove that you can run JavaScript in a way that can be validated on the server." Essentially, Anubis verifies that any visitor to a site is a human using a browser as opposed to a bot. One of the ways it does this is by making the browser do a type of cryptographic math with JavaScript or other subtle checks that browsers do by default but bots have to be explicitly programmed to do. This check is invisible to the user, and most browsers since 2022 are able to complete this test. In theory, bot scrapers could pretend to be users with browsers as well, but the additional computational cost of doing so on the scale of scraping the entire internet would be huge. This way, Anubis creates a computational cost that is prohibitively expensive for AI scrapers that are hitting millions and millions of sites, but marginal for an individual user who is just using the internet like a human.

Anubis is free, open source, lightweight, can be self-hosted, and can be implemented almost anywhere. It also appears to be a pretty good solution for what we've repeatedly reported is a widespread problem across the internet, which helps explain its popularity. But Iaso is still putting a lot of work into improving it and adding features. She told me she's working on a non cryptographic challenge so it taxes users' CPUs less, and also thinking about a version that doesn't require JavaScript, which some privacy-minded disable in their browsers. The biggest challenge in developing Anubis, Iaso said, is finding the balance. "The balance between figuring out how to block things without people being blocked, without affecting too many people with false positives," she said. "And also making sure that the people running the bots can't figure out what pattern they're hitting, while also letting people that are caught in the web be able to figure out what pattern they're hitting, so that they can contact the organization and get help. So that's like, you know, the standard, impossible scenario."

Jack Dorsey Launches a WhatsApp Messaging Rival Built On Bluetooth (cnbc.com) 66

Jack Dorsey has launched Bitchat, a decentralized, peer-to-peer messaging app that uses Bluetooth mesh networks for encrypted, ephemeral chats without requiring accounts, servers, or internet access. The beta version is live on TestFlight, with a full white paper available on GitHub. CNBC reports: In a post on X Sunday, Dorsey called it a personal experiment in "bluetooth mesh networks, relays and store and forward models, message encryption models, and a few other things."

Bitchat enables ephemeral, encrypted communication between nearby devices. As users move through physical space, their phones form local Bluetooth clusters and pass messages from device to device, allowing them to reach peers beyond standard range -- even without Wi-Fi or cell service. Certain "bridge" devices connect overlapping clusters, expanding the mesh across greater distances. Messages are stored only on device, disappear by default and never touch centralized infrastructure -- echoing Dorsey's long-running push for privacy-preserving, censorship-resistant communication.

Like the Bluetooth-based apps used during Hong Kong's 2019 protests, Bitchat is designed to keep working even when the internet is blocked, offering a censorship-resistant way to stay connected during outages, shutdowns or surveillance. The app also supports optional group chats, or "rooms," which can be named with hashtags and protected by passwords. It includes store and forward functionality to deliver messages to users who are temporarily offline. A future update will add WiFi Direct to increase speed and range, pushing Dorsey's vision for off-grid, user-owned communication even further.

The FSF Faces Active 'Ongoing and Increasing' DDoS Attacks (fsf.org) 34

The Free Software Foundation's services face "ongoing (and increasing) distributed denial of service (DDoS) attacks," senior systems administrator Ian Kelling wrote Wednesday. But "Even though we are under active attack, gnu.org, ftp.gnu.org, and savannah.gnu.org are up with normal response times at the moment, and have been for the majority of this week, largely thanks to hard work from the Savannah hackers Bob, Corwin, and Luke who've helped us, your sysadmins."

"We've shielded these sites for almost a full year of intense attacks now, and we'll keep on fighting these attacks for as long as they continue." Our infrastructure has been under attack since August 2024. Large Language Model (LLM) web crawlers have been a significant source of the attacks, and as for the rest, we don't expect to ever know what kind of entity is targeting our sites or why.

- In the fall Bulletin, we wrote about the August attack on gnu.org. That attack continues, but we have mitigated it. Judging from the pattern and scope, the goal was likely to take the site down and it was not an LLM crawler. We do not know who or what is behind the attack, but since then, we have had more attacks with even higher severity.

- To begin with, GNU Savannah, the FSF's collaborative software development system, was hit by a massive botnet controlling about five million IPs starting in January. As of this writing, the attack is still ongoing, but the botnet's current iteration is mitigated. The goal is likely to build an LLM training dataset. We do not know who or what is behind this.

- Furthermore, gnu.org and ftp.gnu.org were targets in a new DDoS attack starting on May 27, 2025. Its goal seems to be to take the site down. It is currently mitigated. It has had several iterations, and each has caused some hours of downtime while we figured out how to defend ourselves against it. Here again, the goal was likely to take our sites down and we do not know who or what is behind this.

- In addition, directory.fsf.org, the server behind the Free Software Directory, has been under attack since June 18. This likely is an LLM scraper designed to specifically target Media Wiki sites with a botnet. This attack is very active and now partially mitigated...

Even though we are under active attack, gnu.org, ftp.gnu.org, and savannah.gnu.org are up with normal response times at the moment, and have been for the majority of this week, largely thanks to hard work from the Savannah hackers Bob, Corwin, and Luke who've helped us, your sysadmins. We've shielded these sites for almost a full year of intense attacks now, and we'll keep on fighting these attacks for as long as they continue.

The full-time FSF tech staff is just two systems administrators, "and we currently lack the funds to hire more tech staff any time soon," Kelling points out. Kelling titled his post "our small team vs millions of bots," suggesting that supporters purchase FSF memberships "to improve our staffing situation... Can you join us in our crucial work to guard user freedom and defy dystopia?"

Kelling also points out they're also facing "run-of-the-mill standard crawlers, SEO crawlers, crawlers pretending to be normal users, crawlers pretending to be other crawlers, uptime systems, vulnerability scanners, carrier-grade network address translation, VPNs, and normal browsers hitting our sites..."

"Some of the abuse is not unique to us, and it seems that the health of the web has some serious problems right now."

Websites Hosting Major US Climate Reports Taken Down (apnews.com) 77

An anonymous reader quotes a report from the Associated Press: Websites that displayed legally mandated U.S. national climate assessments seem to have disappeared, making it harder for state and local governments and the public to learn what to expect in their backyards from a warming world. Scientists said the peer-reviewed authoritative reports save money and lives. Websites for the national assessments and the U.S. Global Change Research Program were down Monday and Tuesday with no links, notes or referrals elsewhere. The White House, which was responsible for the assessments, said the information will be housed within NASA to comply with the law, but gave no further details. Searches for the assessments on NASA websites did not turn them up.

"It's critical for decision makers across the country to know what the science in the National Climate Assessment is. That is the most reliable and well-reviewed source of information about climate that exists for the United States," said University of Arizona climate scientist Kathy Jacobs, who coordinated the 2014 version of the report. "It's a sad day for the United States if it is true that the National Climate Assessment is no longer available," Jacobs said. "This is evidence of serious tampering with the facts and with people's access to information, and it actually may increase the risk of people being harmed by climate-related impacts."

"This is a government resource paid for by the taxpayer to provide the information that really is the primary source of information for any city, state or federal agency who's trying to prepare for the impacts of a changing climate," said Texas Tech climate scientist Katharine Hayhoe, who has been a volunteer author for several editions of the report. Copies of past reports are still squirreled away in NOAA's library. NASA's open science data repository includes dead links to the assessment site. [...] Additionally, NOAA's main climate.gov website was recently forwarded to a different NOAA website. Social media and blogs at NOAA and NASA about climate impacts for the general public were cut or eliminated. "It's part of a horrifying big picture," [said Harvard climate scientist John Holdren, who was President Obama's science advisor and whose office directed the assessments]. "It's just an appalling whole demolition of science infrastructure."
National climate assessments are more detailed and locally relevant than UN reports and undergo rigorous peer review and validation by scientific and federal institutions, Hayhoe and Jacobs said. Suppressing these reports would be censoring science, Jacobs said.

Ripple Applies For US Banking License (cointelegraph.com) 8

Ripple Labs is applying for a U.S. national bank charter and a Federal Reserve master account, "following a similar move by stablecoin issuer Circle Internet Group as crypto firms look to be regulated to deepen ties with traditional finance," reports CoinTelegraph. From the report: Ripple CEO Brad Garlinghouse confirmed on X on Wednesday that the company is applying for a license with the US Office of the Comptroller of the Currency (OCC), following an earlier report by The Wall Street Journal. "True to our long-standing compliance roots, Ripple is applying for a national bank charter from the OCC," he wrote. Garlinghouse said if the license is approved, it would be a "new (and unique!) benchmark for trust in the stablecoin market" as the firm would be under federal and state oversight -- with the New York Department of Financial Services already regulating its Ripple USD (RLUSD) stablecoin. [...]

Ripple's Garlinghouse added that the company also applied for a Master Account with the Federal Reserve, which would give it access to the US central banking system. "This access would allow us to hold $RLUSD reserves directly with the Fed and provide an additional layer of security to future proof trust in RLUSD," Garlinghouse said. "Congress is working towards clear rules and regulations, and banks (in a far cry from the years of Operation Chokepoint 2.0) are leaning in," he added, mentioning the conspiracy that the Biden administration sought to cut off crypto from the financial system. Ripple applied for the account through Standard Custody, a crypto custody firm it acquired in February 2024.

Let's Encrypt Rolls Out Free Security Certs For IP Addresses (theregister.com) 26

Let's Encrypt, a certificate authority (CA) known for its free TLS/SSL certificates, has begun issuing digital certificates for IP addresses. From a report: It's not the first CA to do so. PositiveSSL, Sectigo, and GeoTrust all offer TLS/SSL certificates for use with IP addresses, at prices ranging from $40 to $90 or so annually. But Let's Encrypt does so at no cost.

For those with a static IP address who want to host a website, an IP address certificate provides a way to offer visitors a secure connection with that numeric identifier while avoiding the nominal expense of a domain name.

China's Giant New Gamble With Digital IDs (economist.com) 74

China will launch digital IDs for internet use on July 15th, transferring online verification from private companies to government control. Users obtain digital IDs by submitting personal information including facial scans to police via an app. A pilot program launched one year ago enrolled 6 million people.

The system currently remains voluntary, though officials and state media are pushing citizens to register for "information security." Companies will see only anonymized character strings when users log in, while police retain exclusive access to personal details. The program replaces China's existing system requiring citizens to register with companies using real names before posting comments, gaming, or making purchases.

Police say they punished 47,000 people last year for spreading "rumours" online. The digital ID serves a broader government strategy to centralize data control. State planners classify data as a production factor alongside labor and capital, aiming to extract information from private companies for trading through government-operated data exchanges.

UK Eyes New Law as 1885 Telegraph Act Proves Inadequate for Cable Sabotage (theregister.com) 19

The UK government is preparing new legislation to address undersea cable sabotage as current laws are proving inadequate for modern threats. Ministry of Defence parliamentary under-secretary Luke Pollard told lawmakers yesterday that the Submarine Telegraph Act of 1885, which imposes 1,000 pound ($1,370) fines, "does seem somewhat out of step with the modern-day risk."

The government's Strategic Defence Review proposes a new defence readiness bill to cover state-sponsored cybercrime and subsea cable attacks. Chris Bryant, minister of state for data protection and telecoms, said fines could be increased to 5,000 pound ($6,850) through secondary legislation but "that just doesn't seem to meet the needs of the situation."

Recent incidents include Sweden's deployment of forces to the Baltic Sea following suspected Russian attacks on underwater data cables in January. The China Strategic Risks Institute found that eight of ten identified vessels in 12 sabotage incidents between January 2021 and April 2025 were linked to China or Russia through registration or ownership.

Cloudflare Flips AI Scraping Model With Pay-Per-Crawl System For Publishers (cloudflare.com) 33

Cloudflare today announced a "Pay Per Crawl" program that allows website owners to charge AI companies for accessing their content, a potential revenue stream for publishers whose work is increasingly being scraped to train AI models. The system uses HTTP response code 402 to enable content creators to set per-request prices across their sites. Publishers can choose to allow free access, require payment at a configured rate, or block crawlers entirely.

When an AI crawler requests paid content, it either presents payment intent via request headers for successful access or receives a "402 Payment Required" response with pricing information. Cloudflare acts as the merchant of record and handles the underlying technical infrastructure. The company aggregates billing events, charges crawlers, and distributes earnings to publishers.

Alongside Pay Per Crawl, Cloudflare has switched to blocking AI crawlers by default for its customers, becoming the first major internet infrastructure provider to require explicit permission for AI access. The company handles traffic for 20% of the web and more than one million customers have already activated its AI-blocking tools since their September 2024 launch, it wrote in a blog post.

VP.net Promises "Cryptographically Verifiable Privacy" (torrentfreak.com) 36

TorrentFreak spotlights VP.net, a brand-new service from Private Internet Access founder Andrew Lee (the guy who gifted Linux Journal to Slashdot) that eliminates the classic "just trust your VPN" problem by locking identity-mapping and traffic-handling inside Intel SGX enclaves. The company promises 'cryptographically verifiable privacy' by using special hardware 'safes' (Intel SGX), so even the provider can't track what its users are up to.

The design goal is that no one, not even the VPN company, can link "User X" to "Website Y."

Lee frames it as enabling agency over one's privacy:

"Our zero trust solution does not require you to trust us - and that's how it should be. Your privacy should be up to your choice - not up to some random VPN provider in some random foreign country."

The team behind VP.net includes CEO Matt Kim as well as arguably the first Bitcoin veterans Roger Ver and Mark Karpeles.

Ask Slashdot: Now that there's a VPN where you don't have to "just trust the provider" - arguably the first real zero-trust VPN - are trust based VPNs obsolete?

WordPress CEO Regrets 'Belongs to Me' Comment Amid Ongoing WP Engine Legal Battle (theverge.com) 6

Automattic CEO Matt Mullenweg said he regrets telling the media that "WordPress.org just belongs to me personally" during a new interview about his company's legal dispute with hosting provider WP Engine. The comment has been "taken out of context so many times" and represents "the worst thing ever," Mullenweg said in a new podcast interview with The Verge.

The dispute began when Mullenweg accused WP Engine of "free-riding" on WordPress's open-source ecosystem without contributing adequate resources back to the project. Mullenweg filed a lawsuit against WP Engine while cutting off the company's access to core WordPress technologies. WP Engine countersued, and Automattic was forced to reverse some retaliatory measures.

The controversy triggered significant internal upheaval at Automattic. The company offered "alignment" buyouts to employees who disagreed with the direction, reducing headcount from a peak of 2,100 to approximately 1,500 people. Mullenweg said this was "probably the fourth big time" WordPress has faced such community controversy, though the first in the current media landscape. WordPress powers 43% of websites globally. Mullenweg said he wants to return to "the most collaborative version of WordPress possible" but noted the legal proceedings continue with both sides spending "millions of dollars a month on lawyers."

Has an AI Backlash Begun? (wired.com) 134

"The potential threat of bosses attempting to replace human workers with AI agents is just one of many compounding reasons people are critical of generative AI..." writes Wired, arguing that there's an AI backlash that "keeps growing strong."

"The pushback from the creative community ramped up during the 2023 Hollywood writer's strike, and continued to accelerate through the current wave of copyright lawsuits brought by publishers, creatives, and Hollywood studios." And "Right now, the general vibe aligns even more with the side of impacted workers." "I think there is a new sort of ambient animosity towards the AI systems," says Brian Merchant, former WIRED contributor and author of Blood in the Machine, a book about the Luddites rebelling against worker-replacing technology. "AI companies have speedrun the Silicon Valley trajectory." Before ChatGPT's release, around 38 percent of US adults were more concerned than excited about increased AI usage in daily life, according to the Pew Research Center. The number shot up to 52 percent by late 2023, as the public reacted to the speedy spread of generative AI. The level of concern has hovered around that same threshold ever since...

[F]rustration over AI's steady creep has breached the container of social media and started manifesting more in the real world. Parents I talk to are concerned about AI use impacting their child's mental health. Couples are worried about chatbot addictions driving a wedge in their relationships. Rural communities are incensed that the newly built data centers required to power these AI tools are kept humming by generators that burn fossil fuels, polluting their air, water, and soil. As a whole, the benefits of AI seem esoteric and underwhelming while the harms feel transformative and immediate.

Unlike the dawn of the internet where democratized access to information empowered everyday people in unique, surprising ways, the generative AI era has been defined by half-baked software releases and threats of AI replacing human workers, especially for recent college graduates looking to find entry-level work. "Our innovation ecosystem in the 20th century was about making opportunities for human flourishing more accessible," says Shannon Vallor, a technology philosopher at the Edinburgh Futures Institute and author of The AI Mirror, a book about reclaiming human agency from algorithms. "Now, we have an era of innovation where the greatest opportunities the technology creates are for those already enjoying a disproportionate share of strengths and resources."

The impacts of generative AI on the workforce are another core issue that critics are organizing around. "Workers are more intuitive than a lot of the pundit class gives them credit for," says Merchant. "They know this has been a naked attempt to get rid of people."

The article suggests "the next major shift in public opinion" is likely "when broad swaths of workers feel further threatened," and organize in response...

To Spam AI Chatbots, Companies Spam Reddit with AI-Generated Posts (9to5mac.com) 38

The problem? "Companies want their products and brands to appear in chatbot results," reports 9to5Mac. And "Since Reddit forms a key part of the training material for Google's AI, then one effective way to make that happen is to spam Reddit." Huffman has confirmed to the Financial Times that this is happening, with companies using AI bots to create fake posts in the hope that the content will be regurgitated by chatbots:

"For 20 years, we've been fighting people who have wanted to be popular on Reddit," Huffman said... "If you want to show up in the search engines, you try to do well on Reddit, and now the LLMs, it's the same thing. If you want to be in the LLMs, you can do it through Reddit."

Multiple ad agency execs confirmed to the FT that they are indeed "posting content on Reddit to boost the likelihood of their ads appearing in the responses of generative AI chatbots." Huffman says that AI bots are increasingly being used to make spam posts, and Reddit is trying to block them: For Huffman, success comes down to making sure that posts are "written by humans and voted on by humans [...] It's an arms race, it's a never ending battle." The company is exploring a number of new ways to do this, including the World ID eyeball-scanning device being touted by OpenAI's Sam Altman.

It's Reddit's 20th anniversary, notes CNBC. And while "MySpace, Digg and Flickr have faded into oblivion," Reddit "has refused to die, chugging along and gaining an audience of over 108 million daily users..."

But now Reddit "faces a gargantuan challenge gaining new users, particularly if Google's search floodgates dry up." [I]n the age of AI, many users simply "go the easiest possible way," said Ann Smarty, a marketing and reputation management consultant who helps brands monitor consumer perception on Reddit. And there may be no simpler way of finding answers on the internet than simply asking ChatGPT a question, Smarty said. "People do not want to click," she said. "They just want those quick answers."
But in response, CNBC's headline argues that Reddit "is fighting AI with AI." It launched its own Reddit Answers AI service in December, using technology from OpenAI and Google. Unlike general-purpose chatbots that summarize others' web pages, the Reddit Answers chatbot generates responses based purely on the social media service, and it redirects people to the source conversations so they can see the specific user comments. A Reddit spokesperson said that over 1 million people are using Reddit Answers each week.

AI Improves At Improving Itself Using an Evolutionary Trick (ieee.org) 41

Technology writer Matthew Hutson (also Slashdot reader #1,467,653) looks at a new kind of self-improving AI coding system. It rewrites its own code based on empirical evidence of what's helping — as described in a recent preprint on arXiv.

From Hutson's new article in IEEE Spectrum: A Darwin Gödel Machine (or DGM) starts with a coding agent that can read, write, and execute code, leveraging an LLM for the reading and writing. Then it applies an evolutionary algorithm to create many new agents. In each iteration, the DGM picks one agent from the population and instructs the LLM to create one change to improve the agent's coding ability [by creating "a new, interesting, version of the sampled agent"]. LLMs have something like intuition about what might help, because they're trained on lots of human code. What results is guided evolution, somewhere between random mutation and provably useful enhancement. The DGM then tests the new agent on a coding benchmark, scoring its ability to solve programming challenges...

The researchers ran a DGM for 80 iterations using a coding benchmark called SWE-bench, and ran one for 80 iterations using a benchmark called Polyglot. Agents' scores improved on SWE-bench from 20 percent to 50 percent, and on Polyglot from 14 percent to 31 percent. "We were actually really surprised that the coding agent could write such complicated code by itself," said Jenny Zhang, a computer scientist at the University of British Columbia and the paper's lead author. "It could edit multiple files, create new files, and create really complicated systems."

... One concern with both evolutionary search and self-improving systems — and especially their combination, as in DGM — is safety. Agents might become uninterpretable or misaligned with human directives. So Zhang and her collaborators added guardrails. They kept the DGMs in sandboxes without access to the Internet or an operating system, and they logged and reviewed all code changes. They suggest that in the future, they could even reward AI for making itself more interpretable and aligned. (In the study, they found that agents falsely reported using certain tools, so they created a DGM that rewarded agents for not making things up, partially alleviating the problem. One agent, however, hacked the method that tracked whether it was making things up.)

As the article puts it, the agents' improvements compounded "as they improved themselves at improving themselves..."

Supreme Court Rejects Challenge To FCC Broadband Subsidy Program (nbcnews.com) 58

The Supreme Court ruled Friday that the FCC's Universal Service Fund can continue operating, rejecting claims that the program's funding mechanism violates the Constitution. In a 6-3 decision written by Justice Elena Kagan, the court found that Congress did not exceed its authority when it enacted the 1996 law establishing the fund and that the FCC could delegate administration to a private corporation. The Universal Service Fund subsidizes telecommunications services for low-income consumers, rural health care providers, schools and libraries through fees generally passed on to customers that raise billions of dollars annually.

The program is administered by the Universal Service Administrative Company, a nonprofit the FCC designated to run the fund. Conservative advocacy group Consumers' Research challenged the structure, arguing that "a private company is taxing Americans in amounts that total billions of dollars every year, under penalty of law, without true governmental accountability."

The Fifth Circuit Court of Appeals ruled in favor of Consumers' Research, prompting the FCC to petition the Supreme Court for review. Kagan wrote that Congress "sufficiently guided and constrained the discretion that it lodged with the FCC to implement the universal-service contribution scheme," adding that the FCC "retained all decision-making authority within that sphere." She concluded that "nothing in those arrangements, either separately or together, violates the Constitution." The challengers argued the program violates the "nondelegation doctrine," a conservative legal theory that says Congress has limited powers to delegate its lawmaking authority to the executive branch.

Starlink Helps Eight More Nations Pass 50% IPv6 Adoption (theregister.com) 68

Eight nations have surpassed 50% IPv6 deployment since June 2024, bringing the total number of countries in the majority IPv6 club to 21, according to the Internet Society. Brazil, Guatemala, Hungary, Japan, Mexico, Puerto Rico, Sri Lanka, and Tuvalu all crossed the threshold over the past year.

Tuvalu's adoption coincided with the arrival of Elon Musk's Starlink satellite broadband service, which operates as IPv6-only. The Internet Society's Pulse platform found no IPv6 deployment in the Pacific nation in June 2024, but Starlink now holds 88% market share there and 59% of Tuvalu's internet connections use IPv6.

France moved from third place to tie with India for the global lead at 73% IPv6 deployment. Japan rebounded from 49% to 55%, returning to the 50% club after dropping below the mark in mid-2024. Puerto Rico climbed from 49% to 53%. Thailand appears positioned to join next at 49% deployment, followed by Estonia at 46% and the United Kingdom at 45%.
