For almost two decades, the PackageKit package management abstraction layer has shipped with pkcon as its command-line client. pkcon does its job, but it was always kind of a “testing” front-end for the PackageKit daemon rather than a tool designed for everyday use. The focus has instead been on the GUI tools, automatic system updates, GUI application managers and other front-ends. Its command names mirror the D-Bus API almost one-to-one (get-details, get-updates, get-depends), output is very plain, and there is no machine-readable mode for scripting. Most importantly though, there has been no development on it at all for almost a decade, so pkcon was stuck in its rudimentary state from that era.

Since a lot of changes will be coming to PackageKit, and testing the daemon and working with it from the command-line was not very pleasant anymore in 2025/2026, I decided to modernize the tool as part of my work as fellow for the Sovereign Tech Agency last year. pkgcli is the new command-line client for PackageKit. It is built from the ground up to be pleasant to use interactively and easy to drive from scripts.

Why a new tool?

Of course, instead of introducing a new tool, I could have just expanded pkcon instead. The problem with that approach is that the pkcon utility has been around for so long and its command-line API had ossified so much, that rather than changing it and potentially breaking a lot of scripts relying on its quirks, I decided to introduce a new tool instead. pkcon can still be optionally compiled for people who need it in their scripts and workflows.

The goals for pkgcli, and the features it now has are:

• Human-friendly command names. Verbs that read the way you’d describe the task, instead of mirroring the D-Bus API 1:1: show, search, list-updates, what-provides, instead of get-details and friends.
• Readable, colored output by default (still respecting NO_COLOR and degrading gracefully).
• A real scripting mode. A global --json flag emits JSONL instead of fully human-readable output when possible, to make it easier to use the tool for scripting purposes.
• Sensible defaults. A few defaults have been changed, such as the metadata cache-age, or automatic cleanup of unused dependencies being enabled by default. This is more in line with current defaults by other tools and frontends. We also print package information in a slightly different, more readable way.
• Better handling of internationalized text. Text should now align properly in the terminal window, and we should no longer have completely chaotic text output on non-English locales (especially Chinese/Japanese).

Why not pkgctl?

Originally, this tool was called pkgctl, to match other common cross-distro tool names. However, that name was already taken by an Arch-specific distro development tool. When this issue was raised, we decided to just rename our tool to pkgcli with the next release, to avoid the name clash on Arch Linux.

Examples!

Here are some examples on how to use the new tool (some of which include the abridged output pkgcli prints).

Search for anything containing the string “editor” in name or description, then look at the details of one result:

$ pkgcli search editor Querying [████████████████████████████████████████] 100% ▣ ace-of-penguins 1.5~rc2-7.amd64 [debian-testing-main] ▣ acorn-fdisk 3.0.6-14.amd64 [debian-testing-main] ▣ ardour 1:9.2.0+ds-1.amd64 [debian-testing-main] ✔ audacity 3.7.7+dfsg-1.amd64 [manual:debian-testing-main] ✔ audacity-data 3.7.7+dfsg-1.all [auto:debian-testing-main] ▣ augeas-tools 1.14.1-1.1.amd64 [debian-testing-main] ▣ emacs 1:30.2+1-3.all [debian-testing-main] ▣ gedit 48.1-9+b1.amd64 [debian-testing-main] ▣ gedit-common 48.1-9.all [debian-testing-main] ▣ gedit-dev 48.1-9+b1.amd64 [debian-testing-main] [...] $ pkgcli show nano Package: nano Version: 9.0-1 Summary: small, friendly text editor inspired by Pico Description: GNU nano is an easy-to-use text editor originally designed as a replacement for Pico, the ncurses-based editor from the non-free mailer package Pine.

Search only within package names rather than descriptions:

$ pkgcli search name python3

Check for updates. refresh updates the metadata, then list-updates reports what’s available:

$ pkgcli refresh && pkgcli list-updates Loading cache [████████████████████████████████████████] 100% ▲ cme 1.048-1.all [debian-testing-main] ▲ gir1.2-gdm-1.0 50.1-2.amd64 [debian-testing-main] ▲ imagemagick 8:7.1.2.24+dfsg1-1.amd64 [debian-testing-main] ▲ imagemagick-7-common 8:7.1.2.24+dfsg1-1.all [debian-testing-main] ▲ imagemagick-7.q16 8:7.1.2.24+dfsg1-1.amd64 [debian-testing-main] ▲ libdlrestrictions1 0.22.0.amd64 [debian-testing-main] ▲ libfftw3-bin 3.3.11-1.amd64 [debian-testing-main] ▲ libfftw3-dev 3.3.11-1.amd64 [debian-testing-main]

Explore relationships between packages:

$ pkgcli list-depends inkscape # list what inkscape depends on $ pkgcli list-requiring libappstream5 # list what requires libappstream5

Find the package that provides a capability, here the AV1 GStreamer decoder:

$ pkgcli what-provides "gstreamer1(decoder-video/x-av1)" ✔ gstreamer1.0-plugins-bad 1.28.3-1.amd64 [auto:debian-testing-main]

You can also have JSON output for most commands! Attach --json to any query and pipe the result straight into jq. Each line is a self-contained JSON object:

$ pkgcli --json list-updates | jq -r '.name' cme gir1.2-gdm-1.0 imagemagick imagemagick-7-common imagemagick-7.q16 libdlrestrictions1 libfftw3-bin libfftw3-dev libfftw3-double3 Try it

pkgcli is built by default alongside the rest of PackageKit since PackageKit 1.3.4. If your distribution ships a recent enough PackageKit, it should already be on your PATH. You can read its man page man pkgcli for more information. Feedback, bug reports, and patches are very welcome.

I occasionally see people go through great effort to do end-to-end testing of keyboard input latency. That is fantastic but it requires hardware and patience I don’t, nor will ever, have.

Here is a much simpler way to get about 90% of the value. For example, everything but driver/interrupt handler latency and display link scanout/monitor visibility latency and of course your app side (but you could theoretically rig this up to do that too, inside your app). Not that those aren’t important, but they definitely fall into the category of things I personally cannot control for you.

Keyspeed is a very simple GTK application which uses /dev/uinput to synthesize keypresses. Since it knows the time of provenance, it can compare that to when it gets the event back from compositor delivery.

Wrap all that data up in Sysprof capture marks, pull in some from the compositor (GNOME Shell/Mutter support this), tie in some callgraphs/flamegraphs, and you have a very good overview of what is going on during your keypress.

Run it like this (but remember to chmod back when you’re done less you have attack surface available).

$ sudo chmod 660 /dev/uinput $ git clone https://gitlab.gnome.org/chergert/keypress $ sudo dnf install sysprof-devel libinput-devel gtk4-devel $ make $ sysprof-cli --gtk --gnome-shell capture.syscap -- ./keyspeed $ sysprof capture.syscap

Currently, this only shows you keypress send to receive in GTK, but if someone cared enough, you could make it take the next GtkFrameTimings and use that to get the presentation time. I don’t need that for what I’m doing, so it doesn’t.

If you go to the marks section, you can dive in to a specific keypress/release cycle. Zoom in on just that section, switch back to callgraph/flamegraph profiler and see what was going on.

Pretty simple, no special hardware needed.

You can see how long it took, where time was spent, and more importantly, how much time was empty between things that matter.

An anonymous reader quotes a report from NBC News: The first quarter of 2026 produced the most blocked and delayed data center projects on record, according to a new study shared with NBC News. The study -- conducted by Data Center Watch, a project of the AI intelligence firm 10a Labs that tracks local data center activity -- found that data center opponents blocked or delayed at least 75 projects nationwide worth about $130 billion from January through March, the most in a three-month period since the group began tracking in 2023. "The quarter reflected a structural shift rather than a cyclical spike: communities have internalized an opposition playbook, legislative sessions introduced formal regulatory uncertainty, and the number of active opposition groups more than doubled to 833 across 49 states," the authors wrote, noting that the total number and value of data centers blocked or delayed during the first three months of 2026 roughly matched the total for all of 2025. [...] The report found that legislative pushes for moratoriums on constructing data centers ballooned during the first quarter of 2026, sponsored by lawmakers on both sides of the aisle. The report found such proposals introduced in 14 states from January through March, with Sen. Bernie Sanders, I-Vt., and Rep. Alexandria Ocasio-Cortez, D-N.Y., introducing a federal version. Though none of the proposals has been signed into law, one did reach the desk of Democratic Gov. Janet Mills in Maine. She vetoed it in April. More than 300 bills were introduced in statehouses across the country just in the first six weeks of 2026, the authors found, saying it marked "a clear shift from incentive-focused policies toward regulatory oversight as the scale of energy demands became clearer." What's more, the study found that the number of active grassroots opposition groups across the country more than doubled from 396 at the end of 2025 to 833 by March. The authors found that the states with the most opposition groups through that month were Maryland, Ohio and Texas. "In some cases," they wrote, "opposition mobilized before any project was officially filed, the mere rumor of a data center was enough to trigger organized resistance."

Greetings from Planet Peanut!

Since there’s a whole new generation of GNOME contributors active right now, I’ll do a short reintroduction: Hello, I’m Hylke!

I was a design contributor in the late 2.X, early 3.X days. Mainly icons and theming. I’ve attended many GUADECs.

I’m also the developer of SparkleShare, a Git-based file sync app. Once a much used tool by the Design Team to collaborate on mockups, now in need for some love and care.

After many years just lurking I’m happy to be officially back as a GNOME Foundation member now that Bobby has joined Circle.

App icons created in recent months New plan

I lost my job this year due to the big tech layoffs. Also dealing with burnout, it made me realise I need to go back to working on things that matter to me.

I would love to contribute design full-time.

If you like my work and want to support me, I’m trying to gather enough small monthly sponsors to support me with a basic income. Every little helps.

My focus for 2026:

• Supply a stream of icons to the Linux ecosystem by designing at least one app icon a week. Developers can request free icons.
• Reboot SparkleShare. Finish the rewrite in Rust and redesign the interface with GTK4 and libadwaita.
• Launch a FOSS design service. Make a plan for sustainably assist FOSS communities with product design work.

I will post frequent updates here and on the Fediverse.

Good to be back!

Jeff Bezos says his new AI startup, Prometheus, is working toward an "artificial general engineer" capable of helping design complex physical products such as robots, drugs, manufacturing systems, and rocket engines. The Verge reports: The NYT first reported on Prometheus last November, but now Bezos is sharing more information about the startup after a $12 billion funding round, putting the company at a $41 billion valuation. Bezos serves as co-CEO of Prometheus alongside Vik Bajaj, who co-founded Alphabet's health-focused research group, Verily. The startup currently has around 150 employees. The tools Prometheus intends to build could help develop physical products across several industries, including robotics, drug design, and manufacturing, the NYT reports. "Blue Origin is a perfect example of a company that could benefit from the tools that Prometheus is building," Bezos tells the NYT. "Any company that is building sophisticated devices -- like rocket engines -- would benefit greatly from this kind of technology."

The Justice Department has approved Paramount Skydance's $111 billion acquisition of Warner Bros. Discovery without requiring divestitures or other concessions. The deal still faces scrutiny from state attorneys general. Politico reports: The decision, expected to be announced Friday, paves the way for Paramount to combine with the entertainment and media company behind a vast film and television studio, CNN, and the HBO Max streaming service, which would be combined with Paramount+ to create a new offering boasting about 200 million subscribers. The deal, which would upend the Hollywood ecosystem by combining two historic rival studios, is opposed by many in the entertainment industry who fear it could lead to mass layoffs, among other concerns. After an extensive review, DOJ officials determined the transaction did not pose a threat to competition and declined to challenge it, said the people, who were granted anonymity to discuss sensitive matters. The department approved the merger without requiring any divestitures, behavioral remedies or concessions, according to one of the people. [...] The DOJ's approval does not end the merger's legal scrutiny. California Attorney General Rob Bonta has been reviewing the transaction and could still sue to block the deal despite federal regulators signing off. A spokesperson for Bonta's office told POLITICO earlier this week "the Paramount acquisition of Warner Brothers remains an active investigation." [...] Throughout those discussions, Paramount maintained that the merger would strengthen competition rather than diminish it, creating a media company better positioned to compete with streaming leaders and deep-pocketed technology rivals, according to people familiar with the matter. Hollywood workers fear the merger could trigger another wave of layoffs in an industry already reeling from years of consolidation. Critics argue that billions in promised cost savings will come at the expense of jobs, fewer opportunities for creators and greater concentration of power across film, television and streaming.

ShinyHunters claims it exploited a critical Oracle PeopleSoft zero-day to compromise more than 100 organizations, including the University of Nottingham, where it says it stole 40GB of student and billing data. "ShinyHunters posted the UK university on its data leak site on Tuesday before publishing the stolen files later that same day, presumably because the school refused to pay the extortion demand," reports The Register. From the report: "University of Nottingham on our leak site is one of the first publicly confirmed incidents," a ShinyHunters spokesperson told us. "We have only just started outreach to affected orgs and are actively looking to reach an agreement with affected orgs." They didn't say when they planned to post the other 100 or so claimed victims. A Google threat intelligence report published Thursday afternoon corroborated ShinyHunters' claims to have compromised more than 100 organizations. Google said it spotted malicious activity, "consistent with the exploitation of CVE-2026-35273," between May 27 and June 9, and notified more than 100 global orgs "whose IP addresses correlated with potentially vulnerable endpoints." Most of these, we're told, are based in the US and 68 percent are in the higher-education sector. Oracle has released a "patch availability document," but it's unclear whether a patch is currently available.

An anonymous reader quotes a report from TechCrunch: Google is suing to dismantle the infrastructure behind an alleged massive AI-powered cybercrime operation. On Friday, the tech giant announced a lawsuit against an alleged Chinese cybercrime network called Outsider Enterprise, which Google says uses AI in its campaigns to send scam text messages impersonating Google and other brands to steal passwords and credit card numbers. Outsider Enterprise has financially scammed "hundreds of thousands of victims" with losses "estimated in the millions." The group deployed 9,000 fake websites, 1 million fraudulent web domains, and 2.5 million texts sent to Android users in a two-week period, according to Google. "55,000 spam texts were flagged by Android users in just two weeks this past May -- that's more than two text spam complaints a minute," Google said. Google said it uses "AI-powered tools to fight AI-powered scams", which enable the company to detect scams and alert users of suspicious calls and text messages, leading to the interception of more than 10 billion scam messages a month. The company said it has been collaborating with AT&T, T-Mobile, and Verizon to block the scam text messages and said it is coordinating with the FBI, which is taking unspecified law enforcement actions.

A leaker with a strong Apple rumor track record says a touchscreen MacBook is "100% confirmed. If true, it would mark a major reversal for Apple, which has long argued that the Mac is built for indirect input rather than reaching up to touch a vertical screen. MacRumors reports: Instant Digital has a good track record for Apple rumors and has provided some strikingly accurate information in the past, so it's always worth noting what they have to say about Apple's plans. The claim is also backed by several recent reports. [...] Touchscreen support is expected to be one of several major upgrades coming to Apple's next-generation high-end MacBook Pro models. Other rumored features include M6 Pro and M6 Max chips, an OLED display, a Dynamic Island (i.e., no notch), and a thinner design. The new laptops could also adopt MacBook Ultra branding. Notably, macOS 27 Golden Gate also introduces a more touch-friendly interface, since Apple's Sidecar feature now allows users to tap and interact with macOS interface elements using a finger on their iPad. Apple apparently is not going to advertise the new MacBook Pro/Ultra as a touch-first device like the iPad -- it will be "touch-friendly, not touch-first," according to [Bloomberg's Mark Gurman]. In that sense, Apple will let customers use touch and mouse gestures interchangeably for all functions. Further reading: Steve Jobs Was Wrong About Touchscreen Laptops (2012)

Version:next-20260612 (linux-next) Released:2026-06-12

Longtime Slashdot reader Dotnaught shares a report from The Register: For the past 90 days, Microsoft has been quietly patching a firmware flaw in Surface devices that allowed the hardware to be bricked with a single packet, though only for those who have disabled Secure Core and Secure Boot. And the company's Copilot AI software inadvertently helped identify the faulty firmware. According to Jack Darcy, a security researcher based in Australia, his instance of Microsoft Copilot stumbled across the bug after being asked to adjust the screen backlighting on a Surface device. The Copilot-conjured Python script ended up rendering the researcher's laptop inoperable by overwriting the embedded controller firmware. "Copilot autonomously created and executed four progressively aggressive Python scripts during a probe for backlight control values that sent raw SSAM ioctl commands (SSAM_CDEV_REQUEST = 0xC028A501) directly to the SAM microcontroller through the SAM software path," Darcy explained to The Register. [...] "We appreciate the work of Jack Darcy and The Register for reporting this issue under a coordinated vulnerability disclosure," a Microsoft spokesperson said in a statement. "Our investigation found that a deprecated UEFI interface could trigger a boot loop on some devices. To trigger this loop, the user must have administrator privileges and have already disabled the Secure Boot security feature. We have released updates to address the issue for most impacted devices." That means managed devices are not at risk. But those using Linux, or Windows users who have disabled Secure Core and Secure Boot for gaming, or who use custom Windows drivers, or who have USB boot enabled, may still be vulnerable if their systems haven't received the update. We're uncertain about the range of Surface devices affected. Our source said it appears to be all of them (Surface Laptops 3-6, Surface Book 1-3) except for Surface Go models. ARM variants, however, have not been tested. The report notes that Microsoft is planning to move the Surface stack to a more secure architecture based on Rust code. "Our most recent Surface for Business hardware features a major architectural shift in terms of improved reliability and security that spans our embedded controller, UEFI, but also some of our drivers," said David Abzarian, chief architect for Microsoft Surface. "We're investing in the most secure foundation for a PC by building our embedded controller firmware from the ground up in Rust (as part of leveraging and contributing to the Open Device Partnership (ODP)) in addition to a rewrite of the UEFI DXE Core in Rust; these projects are known as Secure EC and Project Patina respectively." "We're also not only shipping some of our drivers written in Rust, but also helping co-develop the framework Windows Drivers in Rust (WDR) to help enable a broad set of partners in the Windows ecosystem to capitalize on these benefits. I will also note that all of these efforts are open-source promoting one of our key security principles around transparency."

Sam Bankman-Fried lost his appeal to overturn his FTX fraud conviction and 25-year sentence. Reuters reports: In a unanimous decision, a three-judge panel of the Manhattan-based 2nd U.S. Circuit Court of Appeals said prosecutors' evidence against Bankman-Fried "was, conservatively stated, robust." "While he was publicly reassuring customers, investors and regulators that FTX customer funds were safe, he was simultaneously using FTX as his own personal piggy bank, spending customer funds on real estate, political contributions, and investments," Circuit Judge Barrington Parker wrote on behalf of the panel. Bankman-Fried's lawyers did not immediately respond to a request for comment. They may next ask all the active judges on the 2nd Circuit to hear the case, or ask the U.S. Supreme Court to take up the case. Bankman-Fried is also seeking a pardon from President Donald Trump, according to the Justice Department's Office of the Pardon Attorney. Bankman-Fried was sentenced to 25 years in prison in 2024 for "masterminding one of the largest financial frauds in American history," wrote US District Judge Lewis Kaplan. He was convicted on all charges, including wire fraud, conspiracy to commit securities fraud, commodities fraud, and money laundering.

Infineon is set to open a $5.8 billion power-chip fab in Dresden on July 2, backed by about $1.1 billion in EU Chips Act subsidies. The plant will make power semiconductors for AI data centers and could eventually add up to $5.8 billion in annual revenue as demand for AI infrastructure strains global electricity systems. Bloomberg reports: Infineon, traditionally a chipmaker for the automotive industry, has increasingly benefited from soaring demand for power chips used in AI data centers, which will be produced at the new facility. "The AI data centers currently being built and planned around the world will consume twice as much electricity in 2030 as they do today," [said Chief Operating Officer Alexander Gorski]. "That's as much as the entire Federal Republic of Germany." Chip production at the Dresden fab will be scaled over time depending on demand, potentially adding as much as 5 billion euros in revenue per year, Gorski said, declining to comment on when full capacity will be reached. The company has invested around 2 billion euros on construction and the remaining amount will be spent over time to add more machines to the fab, he added. The new facility is "a key catalyst," Bank of America analysts including Didier Scemama wrote in a note last week. Demand from Al customers is materially above Infineon's current capacity, they said, adding the imbalance could improve in the 2027 and 2028 financial years. The analysts raised their Al power revenue forecast for the company by 500 million euros to 4.5 billion euros for 2028. Infineon expects data center-related revenue to rise from around 1.5 billion euros in fiscal 2026 -- roughly 10% of sales -- to 2.5 billion euros in 2027, it said last month. The hundreds of billions of dollars being invested in AI are driving the rapid expansion of data center capabilities around the world. Infineon doesn't produce advanced AI chips, like those designed by Nvidia. But the power semiconductors it plans to produce in Dresden are still needed for AI infrastructure.

An anonymous reader quotes a report from Reuters: Few business leaders have been as deeply embedded in popular culture as Elon Musk, the ambitious entrepreneur who has become a central figure in internet culture and amassed a fortune that has made him the world's first trillionaire. At a time when concerns about inequality are high and public attitudes toward the ultra-wealthy have soured, Musk has managed to retain a loyal following despite his stratospheric net worth and without the folksy persona that endeared other tycoons such as Warren Buffett to the masses. While admirers view Musk's no-filter style as part of his appeal, critics have accused him of wielding oligarch-like power, raised concerns about governance at his companies and objected to his increasingly partisan political interventions. Still, SpaceX, the sprawling rocket, satellite and AI company that together with electric-car maker Tesla form the center of Musk's empire, raised a record $75 billion in its initial public offering on Thursday, highlighting investor enthusiasm for his business ventures. Prior to the share sale, Forbes pegged his net worth at roughly $780 billion, far ahead of the man next in line, Alphabet co-founder Larry Page. "The second richest person has been hovering around $300 billion, so about less than one-third of what Musk can potentially be worth tomorrow," said Matt Durot, deputy editor at Forbes Wealth. "And only one other person, (Oracle founder) Larry Ellison, has ever been worth $400 billion." Most of Musk's wealth now rests with SpaceX, where he holds a stake worth roughly $866 billion. Along with Tesla and the rest of his properties, his net worth will exceed $1.1 trillion when the stock begins trading Friday, according to Forbes and Reuters calculations based on company filings.

Pokemon Go players' optional location scans reportedly helped train Niantic Spatial's visual positioning system, which uses camera imagery and 3D maps to navigate when GPS is unavailable or jammed. According to DroneXL, that technology is now being paired with Vantor's drone navigation software for military and intelligence use, raising questions about whether gamers understood that footage collected for in-game rewards could eventually support defense systems. From the report: The pipeline runs from a mobile game to the battlefield in three steps. Players scanned the physical world. Niantic Spatial turned those scans into a 3D map that lets a machine locate itself by sight when satellite signals fail. And in December 2025, Niantic Spatial announced a partnership with Vantor, the defense and intelligence firm formerly known as Maxar Intelligence, to fuse that ground-level system with Vantor's aerial navigation software for use in GPS-denied operations. I have spent years covering how drones lose their way the moment an electronic warfare unit switches on a jammer, a problem that has spread from the battlefield into civilian airspace, from Ukrainian workshops cycling through navigation generations to American programs scrambling for alternatives. The unsettling part of this story is not the technology. It is where the training data came from, and whether the people who supplied it would have agreed had anyone explained the destination. "Now as part of Scopely (the Saudi-owned company that acquired Niantic last year for $3.5 billion), Pokemon GO data is not shared with Niantic Spatial," a company spokesperson said in a statement to Kotaku. "AR Scans collected through Pokemon GO were submitted voluntarily by players who opted into the feature and were subject to the applicable Terms of Service and Privacy Policy at the time. The discontinuation of AR scanning and the end of data sharing with Niantic Spatial were part of the transition planning associated with Pokemon GO's move to Scopely."

Riverside County has launched an 8-mile "smart freeway" pilot on northbound I-15 near Temecula, using roadway sensors and an algorithm to coordinate ramp meters and suggest speeds rather than widening the freeway. Officials say the $33 million project could reduce stop-and-go traffic and travel times. According to SFGATE, similar systems in Australia and Denver reportedly cutting delays by 20% to 65%. From the report: Unlike typical on-ramp stoplights that run on a timer lasting a few seconds, Interstate 15 drivers could find themselves waiting up to four minutes or even longer while the system determines the necessary speed for traffic entering the freeway. By spacing out the cars, transportation officials hope to improve traffic flow, reduce stop-and-go traffic and decrease the amount of time that travelers have to spend on the freeway. The transportation commission spent $33 million to build the project, which will run for two years. Riverside County Transportation Commission spokesperson David Knudsen told SFGATE that if the program is successful, the agency will work with Caltrans to deploy it elsewhere in the county and then potentially to other traffic choke points in California. "This system is a lot less expensive than trying to build new lanes, and so the idea here is let's make the system that we have work better," he said. Knudsen said the program is not managed by artificial intelligence but instead uses advanced sensors in the roadway to monitor real-time traffic conditions and make adjustments. The stretch of freeway that connects Temecula at the Riverside/San Diego County line to the Interstate 215 interchange in Murrieta can be notoriously clogged. What can be less than a 10-minute drive with no traffic can take between 25 and 45 minutes during the afternoon peak period, according to the transportation commission. "The intent is to create a consistent flow of traffic on the freeway system, and the coordinated ramp metering among the three on-ramps ... will help do that," Knudsen said. "If we can manage that, then we can help prevent that stop-and-go traffic frustration that so many people feel ... on the freeway."

An anonymous reader quotes a report from Bloomberg: While traditional hotspots in the region such as Thailand, South Korea and Malaysia focus on services such as cosmetic surgery, IVF or physicals, China is trying to differentiate itself by providing some of the world's most advanced procedures. "There are two reasons why a patient travels for medical treatments: availability of advanced treatments and price," said Victor Cao, operations director of Joyful Medical, an agency in Shanghai that connects international patients to advanced cancer therapies in China. "Chinese people used to travel overseas for treatments that were not available at home, but now tables have turned." As expanding visa-free policies eased travel in the past year or so, videos are proliferating on social media of foreigners recounting their positive experiences of treatment in China, usually for consumer procedures like acupuncture and tooth scaling. But one treatment that's more quietly gaining traction is CAR-T, among the most promising breakthroughs in oncology but unavailable in most countries, or extremely costly. The process sees doctors collect T cells from the patient's blood then modify them in a lab to produce a special receptor, CAR, that can bind to a specific protein on cancer cells. These engineered cells are then multiplied into large numbers and infused back into the patient. The CAR-T cells seek out cancer cells carrying the target antigen and kill them. In the US, one single infusion can cost between $300,000 to $475,000, according to the American Cancer Society. In China, the equivalent costs about $150,000 to $180,000, and it could get even cheaper -- its drug regulator recently accepted a marketing application for a therapy aimed to be priced below 300,000 yuan ($44,000). China's medical tourism market remains in its infancy. Lecheng International Medical Tourism Pilot Zone in Hainan, which was designated as the country's only special medical zone in 2013, treated just a few thousand foreign medical tourists last year, compared to hundreds of thousands of domestic patients who visited. There, patients can access advanced drugs, devices, and therapies approved in other countries but not elsewhere in mainland China. But China is pushing to upgrade its economy and reshape its global image from just a manufacturing hub into a provider of high-value services, and demand for medical tourism is surging. Globally, the market is estimated at around $34 billion and expected to reach $126 billion by 2035, according to San Francisco-based Grand View Research. Meanwhile, China's sector is projected to grow from $1.3 billion in 2025 to $3.4 billion by 2035, according to New York-based firm Market Research Future. "The patients chose China for something they can't get at home," said Shi Haoying, the group's founder and chief executive officer. "I think the growing attention to medical tourism to China is the inevitable result of long-term accumulation and development in many areas, such as growing medical technologies, quality of service and cost-effectiveness." Jeroen Groenewegen-Lau, an analyst at the Mercator Institute for China Studies, added: "Many new treatments, including in very advanced areas, are made in China but too advanced for the state of its healthcare system and the ability of its patients to pay for these things. It's in China's interest to integrate into the international system."

Two recent studies argue that smartphones may have contributed to falling birthrates by reducing in-person social interaction, sexual frequency, and other conditions tied to unintended pregnancies. "One of the studies published in May is called 'The Collapse of Teen Fertility in the Digital Era' and the other, published just Monday, is titled 'Is the iPhone Birth Control? Causal Evidence from AT&T's 2007-2011 Carrier Monopoly,'" reports KTLA. "Both were chronicled in a New York Times piece by political writer Sabrina Tavernise on Monday." Slashdot reader sabbede submitted the story. From the report: The one from May, authored by two University of Cincinnati professors, posits that teen fertility "collapsed globally" starting around 2007 -- the same year the first iPhone was released. "Smart phones changed how teens spend time with each other ... this change in turn drove the collapse in teen fertility," the study's abstract reads. "Once enough teens are on the phone, being on the phone is where the peer network is; in-person time falls sharply, and with it the unstructured contact in which most unintended teen conceptions occur." The study claimed that countries "across the income and policy spectrum" were affected by the teen fertility drop, and that researchers used data from multiple countries, including the U.S., England and Wales, to rule out "country-specific contraceptive access and welfare reform stories." "This model predicts that the shift towards the phone-mediated equilibrium affects multiple aspects of teen behavior," the abstract continues, concluding that "the same instrument that produces a collapse in teen fertility produces a surge in teen suicides." The study published on Monday looks more closely at the United States, explaining that nationwide general fertility rates have fallen 22% since 2007. "[This is] a sustained decline not readily explained by economic conditions, contraceptive use, housing or childcare costs, or other commonly cited factors," the National Bureau of Economic Researchers study states. "We assess the potential role of a different shock: the diffusion of the smartphone." As mentioned before, the first iPhone was rolled out in 2007, and this study makes use of that timeframe as "a natural experiment" by using data from 2007 through 2011, when iPhones were only sold on AT&T. "From June 2007 through February 2011, the device was sold only on AT&T, allowing us to identify its effect from variation in AT&T's mobile broadband coverage," the study says. "Entropy-balanced Poisson and synthetic difference-in-differences event studies imply that access to the iPhone reduced births by 4.5-8.0% at ages 15-19 and 3.2-6.6% at ages 20-24, with statistically significant but smaller declines among older cohorts. Placebo analyses applied to Verizon and Sprint's pre-2011 coverage footprint are null. Taken together, these cohort effects imply that the diffusion of the iPhone deepened the decline in births among women under 30 while suppressing the rise in births among older women." "Overall, the diffusion of the iPhone explains 33-52% of the decline in the general fertility rate among women aged 15-44," researchers continued. "National-survey evidence on time use and sexual behavior is consistent with the iPhone reducing in-person interactions, increasing pornography use and reducing sexual frequency."

Polish lawmakers have voted to criminalize "trash streaming," with up to five years in prison for online broadcasts of serious crimes such as rape or murder, animal cruelty, humiliating violence, gambling promotion, or even simulated depictions of those acts. Reuters reports: The move is part of a broader push by Poland to tighten regulation of online content. Recent measures include banning the use of mobile phones by children under 16 in schools and introducing stricter age verification rules to access pornography. Under the new provisions, broadcasting crimes punishable by more than five years in prison, including murder or rape, will itself be classed as a separate offence punishable by up to five years behind bars. The law also covers content showing cruelty to animals, violence aimed at humiliating others, and the promotion of gambling. The same penalties will apply to individuals who simulate or falsely portray the commission of such crimes while streaming, lawmakers said.

From white-boarding my ideas on a Google Doc, to writing a formal design document in Crosswords, my ability to communicate technical ideas clearly is being put to the test.

Writing documentation is critical to guide others’ understanding of the code and choices made on a particular codebase. Especially when several developers are introduced to the system, a way to reference material leads to more preparedness to contribute to the codebase.

I wrote a design document introducing the concepts I would like to implement towards creating a way to generate a dynamic grid. Critique is welcome.

Standard libipuz crosswords currently rely on using an existing dictionary to fill a static box of X length x Y width. However, the implementation of vocab puzzles goes against this logic and instead generates a new grid of N length x M width based on a list of 0 <= W <= 30 words of 1 <= L <= 25 characters long.

I reconsidered the idea of using a GArray to store unplaced words because I want something idempotent. To avoid unwanted time complexity bloat, the backend should not carry the memory of unplaced words. Instead, the frontend will compare the generated grid against the original list to manage words that couldn’t be placed.

Integrating this new feature will be a fascinating technical challenge.

I created a new IpuzVocab class which inherits from IpuzCrossword. I learned how GNOME manages its developer documentation by writing a file myself to introduce this class. Writing this document made me think about the whole picture: how vocab puzzles handle grids, clues, and guesses, comparing it to standard crossword puzzles. I wrote the support to display a vocab puzzle in light and dark mode, with my next goal to integrate them via gi-docgen.
