Nvidia is ditching dedicated G-Sync modules to push back against FreeSync’s ubiquity

Nvidia is ditching dedicated G-Sync modules to push back against FreeSync’s ubiquity

Enlarge (credit: Nvidia)

Back in 2013, Nvidia introduced a new technology called G-Sync to eliminate screen tearing and stuttering effects and reduce input lag when playing PC games. The company accomplished this by tying your display's refresh rate to the actual frame rate of the game you were playing, and similar variable refresh-rate (VRR) technology has become a mainstay even in budget monitors and TVs today.

The issue for Nvidia is that G-Sync isn't what has been driving most of that adoption. G-Sync has always required extra dedicated hardware inside of displays, increasing the costs for both users and monitor manufacturers. The VRR technology in most low-end to mid-range screens these days is usually some version of the royalty-free AMD FreeSync or the similar VESA Adaptive-Sync standard, both of which provide G-Sync's most important features without requiring extra hardware. Nvidia more or less acknowledged that the free-to-use, cheap-to-implement VRR technologies had won in 2019 when it announced its "G-Sync Compatible" certification tier for FreeSync monitors. The list of G-Sync Compatible screens now vastly outnumbers the list of G-Sync and G-Sync Ultimate screens.

Today, Nvidia is announcing a change that's meant to keep G-Sync alive as its own separate technology while eliminating the requirement for expensive additional hardware. Nvidia says it's partnering with chipmaker MediaTek to build G-Sync capabilities directly into scaler chips that MediaTek is creating for upcoming monitors. G-Sync modules ordinarily replace these scaler chips, but they're entirely separate boards with expensive FPGA chips and dedicated RAM.

How accurate are wearable fitness trackers? Less than you might think

How accurate are wearable fitness trackers? Less than you might think

Enlarge (credit: Corey Gaskin)

Back in 2010, Gary Wolf, then the editor of Wired magazine, delivered a TED talk in Cannes called “the quantified self.” It was about what he termed a “new fad” among tech enthusiasts. These early adopters were using gadgets to monitor everything from their physiological data to their mood and even the number of nappies their children used.

Wolf acknowledged that these people were outliers—tech geeks fascinated by data—but their behavior has since permeated mainstream culture.

From the smartwatches that track our steps and heart rate, to the fitness bands that log sleep patterns and calories burned, these gadgets are now ubiquitous. Their popularity is emblematic of a modern obsession with quantification—the idea that if something isn’t logged, it doesn’t count.

Your Guide to the Ultimate Home Craps Night

A private craps night will bring the glamor and energy of Vegas to your doorstep. However, don’t let the stress of throwing a craps party take over the enjoyment of the event. Following the right organization plan will help you host a successful game night.

So, roll the dice and immerse yourself in the heart-pounding excitement of craps at home with this ultimate guide.

Get the Equipment

To play this game, you need a collapsible craps table, dice, and casino chips. Or buy a craps party rug and set it up on a long dining table where you can play the game.

Further, consider who will play the role of a casino dealer, a stickman, a shooter, and a boxman around the table from your guests’ list. Alternatively, you can hire a croupier to manage the gameplay if you have enough cash.

Once everything is ready, you can use the table setting to play a game like $10 craps tables in Vegas. Using authentic gaming equipment will provide a realistic gambling experience, making your crap night unforgettable.

Set the Mood

It’s a casino-themed party. That said, replicate traditional casino floors while decorating your home. So, invest in glitzy party props and supplies, such as giant dice, Las Vegas posters, large feathers, and anything that suits your casino decor idea.

Make arrangements for delicious refreshments like craps-themed cupcakes, beverages, mini sandwiches, canapes, chips, and dips. If you want to make it grand, consider hiring a live DJ or band group.

Create a glam, inviting atmosphere by choosing bright, vibrant lighting like chandeliers and table lamps. You can also add a banner to your entrance reading: “Welcome to the Home Casino.”

The goal is to let your guests feel like they’re entering a real casino as soon as they enter your door.

Finalize a Dress Code

As you know, casino clubs follow a dress code. You can also choose from Black Tie or White Tie formals for your at-home crap night.

Add it to your invitation card or email to encourage your guests to follow the same dress code.

Invite Your Guests

Get ready to throw your crap night party by sending an invite to your family and friends. The more, the merrier. You can call up to 20 players to join your craps party.

Image2

However, choosing the right players matters. So, invite people who know the game rules to have an ultimate gaming experience while competing with the pros.

Tips to Play Craps: Essential Rules To Know

In-home craps nights will allow the host to practice craps while having a great time with the close ones. So follow these tips to stay prepared for what’s coming during your casino party.

  • Set a bankroll and starting bet limit. This way, you all can place a stake based on your budget.
  • The game’s format requires players to increase their wager. If you lose, it’ll be a significant loss. On the contrary, there’s also a high winning potential.
  • Like any gambling genre, risk is a significant factor in craps. So, play with a mindset that you won’t win each time the dice is rolled.
  • Pass Line and Don’t Pass bets are the core of a craps game-winning strategy. However, a Pass Line wager has a slightly higher house edge than a Don’t Pass bet, i.e., 1.41%.
  • There are various betting strategies to enhance your winning chances, such as craps odds, iron cross, 6/8 craps, 3 Point Molly, Press and Pull, and YOLO. Take expert players from your guest list head-on by acing any of these craps betting techniques.

FAQs

1. Is craps a skill or luck?

Like many casino games, craps is also a game of chance. Players will be betting against random numbers during the game. However, learning basic rules and strategies is vital to play wisely.

Image1

2. What is a Pass Line bet?

You’ll wager on 7 or 11 while playing the Pass Line bet on the first throw of the dice. If the shooter rolls a 7 or 11, you win the bet. However, you’ll lose on a roll of a 2, 3, or 12. At this point, select a new shooter for the next come-out roll.

3. What is a Don’t Pass Line bet?

In this bet, you’ll place a stake on the don’t pass line, not the pass line. You’ll be called the wrong player if you wager against the shooter. You’ll win the wager if a shooter throws a 2 or 3. However, you’ll lose a game on a roll of 7 or 11.

Wrapping It Up

Craps night can be a great weekend party idea to enjoy with friends or raise money for a good cause. So, have fun while playing responsibly. Make it an event to remember for yourself and your guests.

Od: Abhijit
what-is-the-difference-between-mkv-and-mp4

MKV and MP4 | MKV vs MP4

MKV and MP4 are both digital multimedia container formats used to store audio, video, subtitles, and other data in a single file. These formats are designed to wrap various types of multimedia content into a single file for efficient storage and playback.

MKV (Matroska Video):

  • MKV is a type of digital file format used for videos, kind of like a digital container.
  • People like MKV because it can hold different types of video, audio, and text like subtitles all in one file.
  • It's flexible and can work with lots of different video and audio types.
  • Some people use MKV for things like adding chapters or menus to their videos.
  • Just remember, not all devices and programs can play MKV files as easily as they can play MP4.

MP4 (MPEG-4 Part 14):

  • MP4 is another type of digital file format, like a container for multimedia.
  • Lots of devices and software can handle MP4 files, so it's very popular.
  • It usually uses common video and audio types, making it widely compatible.
  • Most online streaming services and smartphones use MP4 as their standard format.
  • While it might not have as many fancy features as MKV, it's great for making sure your videos work on most devices.

Difference Between MP4 And MKV

Description:

  • MP4, which stands for MPEG-4 Part 14, was created by a group of experts known as the Moving Picture Experts Group. This format is compatible with a variety of video codecs, including H.264, along with numerous others. MP4 enjoys widespread support across most contemporary devices.
  • On the other hand, MKV, short for Matroska Video, serves as a video format capable of housing multiple audio and subtitle tracks within a single file. It has gained substantial popularity as a preferred choice for storing movies.

Pros:

  • MP4 Offers a small file size while delivering excellent video quality. Compatible with a wide range of devices and websites.
  • MKVProvides a small file size without compromising on video quality. Can store multiple audio and subtitle options.

Cons:

  • Adding soft subtitles and multiple audio tracks to MP4 videos can be challenging.
  • Some devices may not support MKV files, and it's not possible to upload MKV files directly to YouTube.

File size:

  • MP4 have relatively small file size
  • In MKV the file size is relatively small, but it could increase if there are numerous audio tracks. [no_toc]

Chip Industry Week in Review

Okinawa Institute of Science and Technology proposed a new EUV litho technology using only four reflective mirrors and a new method of illumination optics that it claims will use 1/10 the power and cost half as much as existing EUV technology from ASML.

Applied Materials may not receive expected U.S. funding to build a $4 billion research facility in Sunnyvale, CA, due to internal government disagreements over how to fund chip R&D, according to Bloomberg.

SEMI published a position paper this week cautioning the European Union against imposing additional export controls to allow companies, encouraging them to  be “as free as possible in their investment decisions to avoid losing their agility and relevance across global markets.” SEMI’s recommendations on outbound investments are in response to the European Economic Security Strategy and emphasize the need for a transparent and predictable regulatory framework.

The U.S. may restrict China’s access to HBM chips and the equipment needed to make them, reports Bloomberg. Today those chips are manufactured by two Korean-based companies, Samsung and SK hynix, but U.S.-based Micron expects to begin shipping 12-high stacks of HBM3E in 2025, and is currently working on HBM4.

Synopsys executive chair and founder Dr. Aart de Geus was named the winner of the Semiconductor Industry Association’s Robert N. Noyce Award. De Geus was selected due to his contributions to EDA technology over a career spanning more than four decades.

The top three foundries plan to implement high-NA EUV lithography as early as 2025 for the 18 angstrom generation, but the replacement of single exposure high-NA (0.55) over double patterning with standard EUV (NA = 0.33) depends on whether it provides better results at a reasonable cost per wafer.

OpenAI has the tech to watermark ChatGPT text—it just won’t release it

OpenAI logo displayed on a phone screen and ChatGPT website displayed on a laptop screen.

Enlarge (credit: Getty Images)

According to The Wall Street Journal, there's internal conflict at OpenAI over whether or not to release a watermarking tool that would allow people to test text to see whether it was generated by ChatGPT or not.

To deploy the tool, OpenAI would make tweaks to ChatGPT that would lead it to leave a trail in the text it generates that can be detected by a special tool. The watermark would be undetectable by human readers without the tool, and the company's internal testing has shown that it does not negatively affect the quality of outputs. The detector would be accurate 99.9 percent of the time. It's important to note that the watermark would be a pattern in the text itself, meaning it would be preserved if the user copies and pastes the text or even if they make modest edits to it.

Some OpenAI employees have campaigned for the tool's release, but others believe that would be the wrong move, citing a few specific problems.

Chrome’s Manifest V3, and its changes for ad blocking, are coming real soon

Chrome logo, squared off in the style of a popular ad-blocking logo

Enlarge (credit: Ron Amadeo)

Google Chrome's long, long project to implement a new browser extension platform is seemingly going to happen, for real, after six years of cautious movement.

One of the first ways people are seeing this is if they use uBlock Origin, a popular ad-blocking extension, as noted by Bleeping Computer. Recently, Chrome users have seen warnings pop up that "This extension may soon no longer be supported," with links asking the user to "Remove or replace it with similar extensions" from Chrome's Web Store. You might see a similar warning on some extensions if you head to Chrome's Extensions page (chrome://extensions).

What's happening is Chrome preparing to make Manifest V3 required for extensions that want to run on its platform. First announced in 2018, the last word on Manifest V3 was that V2 extensions would start being nudged out in early June on the Beta, Dev, and Canary update channels. Users will be able to manually re-enable V2 extensions "for a short time," Google has said, "but over time, this toggle will go away as well." The shift for enterprise Chrome deployments is expected to be put off until June 2025.

Secure Low-Cost In-DRAM Trackers For Mitigating Rowhammer (Georgia Tech, Google, Nvidia)

A new technical paper titled “MINT: Securely Mitigating Rowhammer with a Minimalist In-DRAM Tracker” was published by researchers at Georgia Tech, Google, and Nvidia.

Abstract
“This paper investigates secure low-cost in-DRAM trackers for mitigating Rowhammer (RH). In-DRAM solutions have the advantage that they can solve the RH problem within the DRAM chip, without relying on other parts of the system. However, in-DRAM mitigation suffers from two key challenges: First, the mitigations are synchronized with refresh, which means we cannot mitigate at arbitrary times. Second, the SRAM area available for aggressor tracking is severely limited, to only a few bytes. Existing low-cost in-DRAM trackers (such as TRR) have been broken by well-crafted access patterns, whereas prior counter-based schemes require impractical overheads of hundreds or thousands of entries per bank. The goal of our paper is to develop an ultra low-cost secure in-DRAM tracker.

Our solution is based on a simple observation: if only one row can be mitigated at refresh, then we should ideally need to track only one row. We propose a Minimalist In-DRAM Tracker (MINT), which provides secure mitigation with just a single entry. At each refresh, MINT probabilistically decides which activation in the upcoming interval will be selected for mitigation at the next refresh. MINT provides guaranteed protection against classic single and double-sided attacks. We also derive the minimum RH threshold (MinTRH) tolerated by MINT across all patterns. MINT has a MinTRH of 1482 which can be lowered to 356 with RFM. The MinTRH of MINT is lower than a prior counter-based design with 677 entries per bank, and is within 2x of the MinTRH of an idealized design that stores one-counter-per-row. We also analyze the impact of refresh postponement on the MinTRH of low-cost in-DRAM trackers, and propose an efficient solution to make such trackers compatible with refresh postponement.”

Intel is offering extended warranties for crashing 13th- and 14th-gen desktop CPUs

Even mainstream CPUs like the Core i5-13400 could theoretically be affected by Intel's crashing issues.

Intel will be releasing a microcode update to prevent further damage to crashing 13th- and 14th-generation desktop processors sometime this month if it can stick to its previously announced schedule. This fix should be available via BIOS updates from PC and motherboard makers and from Microsoft as a Windows update. But it will take time for those updates to roll out to users, and Intel has said that processors that are already exhibiting crashes have been permanently damaged and won't be fixed by the microcode update.

In an effort to provide peace of mind to buyers and cover anyone whose CPU is subtly damaged but not showing explicit signs of instability, Intel is extending the warranty on all affected 13th- and 14th-generation CPUs by an additional two years, Tom's Hardware reports. This raises the warranty on a new boxed Intel CPU from three years to five. For processors that came installed in pre-built PCs, Intel says users should reach out to their PC's manufacturer for support instead.

Though owners of high-end chips like the Core i9-13900K and Core i9-14900K were the most frequently affected by the crashing issue, Intel says that any 13th- or 14th-generation desktop CPU with a base power of 65 W or higher could ultimately be affected. This means that even slower, more budget-oriented chips like the Core i5-13400 could end up having problems.

A few weeks with the Pocket 386, an early-‘90s-style, half-busted retro PC

The Pocket 386 is fun for a while, but the shortcomings and the broken stuff start to wear on you after a while.

The Book 8088 was a neat experiment, but as a clone of the original IBM PC, it was pretty limited in what it could do. Early MS-DOS apps and games worked fine, and the very first Windows versions ran… technically. Just not the later ones that could actually run Windows software.

The Pocket 386 laptop is a lot like the Book 8088, but fast-forwarded to the next huge evolution in the PC’s development. Intel’s 80386 processors not only jumped from 16-bit operation to 32-bit, but they implemented different memory modes that could take advantage of many megabytes of memory while maintaining compatibility with apps that only recognized the first 640KB.

Expanded software compatibility makes this one more appealing to retro-computing enthusiasts since (like a vintage 386) it will do just about everything an 8088 can do, with the added benefit of a whole lot more speed and much better compatibility with seminal versions of Windows. It’s much more convenient to have all this hardware squeezed into a little laptop than in a big, clunky vintage desktop with slowly dying capacitors in it.

Two Companies Plan to Fuel Cargo Ships With Ammonia



In July, two companies announced a collaboration aimed at helping to decarbonize maritime fuel technology. The companies, Brooklyn-based Amogy and Osaka-based Yanmar, say they plan to combine their respective areas of expertise to develop power plants for ships that use Amogy’s advanced technology for cracking ammonia to produce hydrogen fuel for Yanmar’s hydrogen internal combustion engines.

This partnership responds directly to the maritime industry’s ambitious goals to significantly reduce greenhouse gas emissions. The International Maritime Organization (IMO) has set stringent targets. It is calling for a 40 percent reduction in shipping’s carbon emissions from 2008 levels by 2030. But will the companies have a commercially available reformer-engine unit available in time for shipping fleet owners to launch vessels featuring this technology by the IMO’s deadline? The urgency is there, but so are the technical hurdles that come with new technologies.

Shipping accounts for less than 3 percent of global human-caused CO2 emissions, but decarbonizing the industry would still have a profound impact on global efforts to combat climate change. According to the IMO’s 2020 Fourth Greenhouse Gas Study, shipping produced 1,056 million tonnes of carbon dioxide in 2018.

Amogy and Yanmar did not respond to IEEE Spectrum‘s requests for comment about the specifics of how they plan to synergize their areas of focus. But John Prousalidis, a professor at the National Technical University of Athens’s School of Naval Architecture and Marine Engineering, spoke with Spectrum to help put the announcement in context.

“We have a long way to go. I don’t mean to sound like a pessimist, but we have to be very cautious.” —John Prousalidis, National Technical University of Athens

Prousalidis is among a group of researchers pushing for electrification of seaport activities as a means of cutting greenhouse gas emissions and reducing the amount of pollutants such as nitrogen oxides and sulfur oxides being spewed into the air by ships at berth and by the cranes, forklifts, and trucks that handle shipping containers in ports. He acknowledged that he hasn’t seen any information specific to Amogy and Yanmar’s technical ideas for using ammonia as ships’ primary fuel source for propulsion, but he has studied maritime sector trends long enough—and helped create standards for the IEEE, the International Electrotechnical Commission (IEC), and the International Organization for Standardization (ISO)—in order to have a strong sense of how things will likely play out.

“We have a long way to go,” Prousalidis says. “I don’t mean to sound like a pessimist, but we have to be very cautious.” He points to NASA’s Artemis project, which is using hydrogen as its primary fuel for its rockets.

“The planned missile launch for a flight to the moon was repeatedly postponed because of a hydrogen leak that could not be well traced,” Prousalidis says. “If such a problem took place with one spaceship that is the singular focus of dozens of people who are paying attention to the most minor detail, imagine what could happen on any of the 100,000 ships sailing across the world?”

What’s more, he says, bold but ultimately unsubstantiated announcements from companies are fairly common. Amogy and Yanmar aren’t the first companies to suggest tapping into ammonia for cargo ships—the industry is no stranger to plans to adopt the fuel to move massive ships across the world’s oceans.

“A couple of big pioneering companies have announced that they’re going to have ammonia-fueled ship propulsion pretty soon,” Prousalidis says. “Originally, they announced that it would be available at the end of 2022. Then they said the end of 2023. Now they’re saying something about 2025.”

Shipping produced 1,056 million tonnes of carbon dioxide in 2018.

Prousalidis adds, “Everybody keeps claiming that ‘in a couple of years’ we’ll have [these alternatives to diesel for marine propulsion] ready. We periodically get these announcements about engines that will be hydrogen-ready or ammonia-ready. But I’m not sure what will happen during real operation. I’m sure that they performed several running tests in their industrial units. But in most cases, according to Murphy’s Law, failures will take place at the worst moment that we can imagine.”

All that notwithstanding, Prousalidis says he believes these technical hurdles will someday be solved, and engines running on alternative fuels will replace their diesel-fueled counterparts eventually. But he says he sees the rollout likely mirroring the introduction of natural gas. At the point when a few machines capable of running on that type of fuel were ready, the rest of the logistics chain was not. “We need to have all these brand-new pieces of equipment, including piping, that must be able to withstand the toxicity and combustibility of these new fuels. This is a big challenge, but it means that all engineers have work to do.”

Spectrum also reached out to researchers at the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy with several questions about what Amogy and Yanmar say they are looking to pull off. The DOE’s e-mail response: “Theoretically possible, but we don’t have enough technical details (temperature of coupling engine to cracker, difficulty of manifolding, startup dynamics, controls, etc.) to say for certain and if it is a good idea or not.”

A Bosch Engineer Speeds Hybrid Race Cars to the Finish Line

Od: Edd Gent


When it comes to motorsports, the need for speed isn’t only on the racetrack. Engineers who support race teams also need to work at a breakneck pace to fix problems, and that’s something Aakhilesh Singhania relishes.

Singhania is a senior applications engineer at Bosch Engineering, in Novi, Mich. He develops and supports electronic control systems for hybrid race cars, which feature combustion engines and battery-powered electric motors.

Aakhilesh Singhania


Employer:

Bosch Engineering

Occupation:

Senior applications engineer

Education:

Bachelor’s degree in mechanical engineering, Manipal Institute of Technology, India; master’s degree in automotive engineering, University of Michigan, Ann Arbor

His vehicles compete in two iconic endurance races: the Rolex 24 at Daytona in Daytona Beach, Fla., and the 24 Hours of Le Mans in France. He splits his time between refining the underlying technology and providing trackside support on competition day. Given the relentless pace of the racing calendar and the intense time pressure when cars are on the track, the job is high octane. But Singhania says he wouldn’t have it any other way.

“I’ve done jobs where the work gets repetitive and mundane,” he says. “Here, I’m constantly challenged. Every second counts, and you have to be very quick at making decisions.”

An Early Interest in Motorsports

Growing up in Kolkata, India, Singhania picked up a fascination with automobiles from his father, a car enthusiast.

In 2010, when Singhania began his mechanical engineering studies at India’s Manipal Institute of Technology, he got involved in the Formula Student program, an international engineering competition that challenges teams of university students to design, build, and drive a small race car. The cars typically weigh less than 250 kilograms and can have an engine no larger than 710 cubic centimeters.

“It really hooked me,” he says. “I devoted a lot of my spare time to the program, and the experience really motivated me to dive further into motorsports.”

One incident in particular shaped Singhania’s career trajectory. In 2013, he was leading Manipal’s Formula Student team and was one of the drivers for a competition in Germany. When he tried to start the vehicle, smoke poured out of the battery, and the team had to pull out of the race.

“I asked myself what I could have done differently,” he says. “It was my lack of knowledge of the electrical system of the car that was the problem.” So, he decided to get more experience and education.

Learning About Automotive Electronics

After graduating in 2014, Singhania began working on engine development for Indian car manufacturer Tata Motors in Pune. In 2016, determined to fill the gaps in his knowledge about automotive electronics, he left India to begin a master’s degree program in automotive engineering at the University of Michigan in Ann Arbor.

He took courses in battery management, hybrid controls, and control-system theory, parlaying this background into an internship with Bosch in 2017. After graduation in 2018, he joined Bosch full-time as a calibration engineer, developing technology for hybrid and electric vehicles.

Transitioning into motorsports required perseverance, Singhania says. He became friendly with the Bosch team that worked on electronics for race cars. Then in 2020 he got his big break.

That year, the U.S.-based International Motor Sports Association and the France-based Automobile Club de l’Ouest created standardized rules to allow the same hybrid race cars to compete in both the Sportscar Championship in North America, host of the famous Daytona race, and the global World Endurance Championship, host of Le Mans.

The Bosch motorsports team began preparing a proposal to provide the standardized hybrid system. Singhania, whose job already included creating simulations of how vehicles could be electrified, volunteered to help.

“I’m constantly challenged. Every second counts, and you have to be very quick at making decisions.”

The competition organizers selected Bosch as lead developer of the hybrid system that would be provided to all teams. Bosch engineers would also be required to test the hardware they supplied to each team to ensure none had an advantage.

“The performance of all our parts in all the cars has to fall within 1 percent of each other,” Singhania says.

After Bosch won the contract, Singhania officially became a motorsports calibration engineer, responsible for tweaking the software to fit the idiosyncrasies of each vehicle.

In 2022 he stepped up to his current role: developing software for the hybrid control unit (HCU), which is essentially the brains of the vehicle. The HCU helps coordinate all of the different subsystems such as the engine, battery, and electric motor and is responsible for balancing power requirements among these different components to maximize performance and lifetime.

Bosch’s engineers also designed software known as an equity model, which runs on the HCU. It is based on historical data collected from the operation of the hybrid systems’ various components, and controls their performance in real time to ensure all the teams’ hardware operates at the same level.

In addition, Singhania creates simulations of the race cars, which are used to better understand how the different components interact and how altering their configuration would affect performance.

Troubleshooting Problems on Race Day

Technology development is only part of Singhania’s job. On race days, he works as a support engineer, helping troubleshoot problems with the hybrid system as they crop up. Singhania and his colleagues monitor each team’s hardware using computers on Bosch’s race-day trailer, a mobile nerve center hardwired to the organizers’ control center on the race track.

“We are continuously looking at all the telemetry data coming from the hybrid system and analyzing [the system’s] health and performance,” he says.

If the Bosch engineers spot an issue or a team notifies them of a problem, they rush to the pit stall to retrieve a USB stick from the vehicle, which contains detailed data to help them diagnose and fix the issue.

After the race, the Bosch engineers analyze the telemetry data to identify ways to boost the standardized hybrid system’s performance for all the teams. In motorsports, where the difference between winning and losing can come down to fractions of a second, that kind of continual improvement is crucial.

Customers “put lots of money into this program, and they are there to win,” Singhania says.

Breaking Into Motorsports Engineering

Many engineers dream about working in the fast-paced and exciting world of motorsports, but it’s not easy breaking in. The biggest lesson Singhania learned is that if you don’t ask, you don’t get invited.

“Keep pursuing them because nobody’s going to come to you with an offer,” he says. “You have to keep talking to people and be ready when the opportunity presents itself.”

Demonstrating that you have experience contributing to challenging projects is a big help. Many of the engineers Bosch hires have been involved in Formula Student or similar automotive-engineering programs, such as the EcoCAR EV Challenge, says Singhania.

The job isn’t for everyone, though, he says. It’s demanding and requires a lot of travel and working on weekends during race season. But if you thrive under pressure and have a knack for problem solving, there are few more exciting careers.

IEEE Educational Video for Kids Spotlights Climate Change



When it comes to addressing climate change, the “in unity there’s strength” adage certainly applies.

To support IEEE’s climate change initiative, which highlights innovative solutions and approaches to the climate crisis, IEEE’s TryEngineering program has created a collection of lesson plans, activities, and events that cover electric vehicles, solar and wind power systems, and more.

TryEngineering, a program within IEEE Educational Activities, aims to foster the next generation of technology innovators by providing preuniversity educators and students with resources.

To help bring the climate collection to more students, TryEngineering has partnered with the Museum of Science in Boston. The museum, one of the world’s largest science centers, reaches nearly 5 million people annually through its physical location, nearby classrooms, and online platforms.

TryEngineering worked with the museum to distribute a nearly four-minute educational video created by Moment Factory, a multimedia studio specializing in immersive experiences. Using age-appropriate language, the video, which is posted on TryEngineering’s climate change page, explores the issue through visual models and scientific explanations.

“Since the industrial revolution, humans have been digging up fossil fuels and burning them, which releases CO2 into the atmosphere in unprecedented quantities,” the video says. It notes that in the past 60 years, atmospheric carbon dioxide increased at a rate 100 times faster than previous natural changes.

“We are committed to energizing students around important issues like climate change and helping them understand how engineering can make a difference.”

The video explains the impact of pollutants such as lead and ash, and it adds that “when we work together, we can change the global environment.” The video encourages students to contribute to a global solution by making small, personal changes.

“We’re thrilled to contribute to the IEEE climate change initiative by providing IEEE volunteers and educators access to TryEngineering’s collection, so they have resources to use with students,” says Debra Gulick, director of IEEE student and academic education programs.

“We are excited to partner with the Museum of Science to bring even more awareness and exposure of this important issue to the school setting,” Gulick says. “Working with prominent partners like the museum, we are committed to energizing students around important issues like climate change and helping them understand how engineering can make a difference.”

For EVs, Semi-Solid-State Batteries Offer a Step Forward



Earlier this month, China announced that it is pouring 6 billion yuan (about US $826 million) into a fund meant to spur the development of solid-state batteries by the nation’s leading battery manufacturers. Solid-state batteries use electrolytes of either glass, ceramic, or solid polymer material instead of the liquid lithium salts that are in the vast majority of today’s electric vehicle (EV) batteries. They’re greatly anticipated because they will have three or four times as much energy density as batteries with liquid electrolytes, offer more charge-discharge cycles over their lifetimes, and be far less susceptible to the thermal runaway reaction that occasionally causes lithium batteries to catch fire.

But China’s investment in the future of batteries won’t likely speed up the timetable for mass production and use in production vehicles. As IEEE Spectrum pointed out in January, it’s not realistic to look for solid-state batteries in production vehicles anytime soon. Experts Spectrum consulted at the time “noted a pointed skepticism toward the technical merits of these announcements. None could isolate anything on the horizon indicating that solid-state technology can escape the engineering and ‘production hell’ that lies ahead.”

“To state at this point that any one battery and any one country’s investments in battery R&D will dominate in the future is simply incorrect.” —Steve W. Martin, Iowa State University

Reaching scale production of solid-state batteries for EVs will first require validating existing solid-state battery technologies—now being used for other, less demanding applications—in terms of performance, life-span, and relative cost for vehicle propulsion. Researchers must still determine how those batteries take and hold a charge and deliver power as they age. They’ll also need to provide proof that a glass or ceramic battery can stand up to the jarring that comes with driving on bumpy roads and certify that it can withstand the occasional fender bender.

Here Come Semi-Solid-State Batteries

Meanwhile, as the world waits for solid electrolytes to shove liquids aside, Chinese EV manufacturer Nio and battery maker WeLion New Energy Technology Co. have partnered to stake a claim on the market for a third option that splits the difference: semi-solid-state batteries, with gel electrolytes.

CarNewsChina.com reported in April that the WeLion cells have an energy density of 360 watt-hours per kilogram. Fully packaged, the battery’s density rating is 260 Wh/kg. That’s still a significant improvement over lithium iron phosphate batteries, whose density tops out at 160 Wh/kg. In tests conducted last month with Nio’s EVs in Shanghai, Chengdu, and several other cities, the WeLion battery packs delivered more than 1,000 kilometers of driving range on a single charge. Nio says it plans to roll out the new battery type across its vehicle lineup beginning this month.

But the Beijing government’s largesse and the Nio-WeLion partnership’s attempt to be first to get semi-solid-state batteries into production vehicles shouldn’t be a temptation to call the EV propulsion game prematurely in China’s favor.

So says Steve W. Martin, a professor of materials science and engineering at Iowa State University, in Ames. Martin, whose research areas include glassy solid electrolytes for solid-state lithium batteries and high-capacity reversible anodes for lithium batteries, believes that solid-state batteries are the future and that hybrid semi-solid batteries will likely be a transition between liquid and solid-state batteries. However, he says, “to state at this point that any one battery and any one country’s investments in battery R&D will dominate in the future is simply incorrect.” Martin explains that “there are too many different kinds of solid-state batteries being developed right now and no one of these has a clear technological lead.”

The Advantages of Semi-Solid-State Batteries

The main innovation that gives semi-solid-state batteries an advantage over conventional batteries is the semisolid electrolyte from which they get their name. The gel electrolyte contains ionic conductors such as lithium salts just as liquid electrolytes do, but the way they are suspended in the gel matrix supports much more efficient ion conductivity. Enhanced transport of ions from one side of the battery to the other boosts the flow of current in the opposite direction that makes a complete circuit. This is important during the charging phase because the process happens more rapidly than it can in a battery with a liquid electrolyte. The gel’s structure also resists the formation of dendrites, the needlelike structures that can form on the anode during charging and cause short circuits. Additionally, gels are less volatile than liquid electrolytes and are therefore less prone to catching fire.

Though semi-solid-state batteries won’t reach the energy densities and life-spans that are expected from those with solid electrolytes, they’re at an advantage in the short term because they can be made on conventional lithium-ion battery production lines. Just as important, they have been tested and are available now rather than at some as yet unknown date.

Semi-solid-state batteries can be made on conventional lithium-ion battery production lines.

Several companies besides WeLion are actively developing semi-solid-state batteries. China’s prominent battery manufacturers, including CATL, BYD, and the state-owned automakers FAW Group and SAIC Group are, like WeLion, beneficiaries of Beijing’s plans to advance next-generation battery technology domestically. Separately, the startup Farasis Energy, founded in Ganzhou, China, in 2009, is collaborating with Mercedes-Benz to commercialize advanced batteries.

The Road Forward to Solid-State Batteries

U.S. startup QuantumScape says the solid-state lithium metal batteries it’s developing will offer energy density of around 400 Wh/kg. The company notes that its cells eliminate the charging bottleneck that occurs in conventional lithium-ion cells, where lithium must diffuse into the carbon particles. QuantumScape’s advanced batteries will therefore allow fast charging from 10 to 80 percent in 15 minutes. That’s a ways off, but the Silicon Valley–based company announced in March that it had begun shipping its prototype Alpha-2 semi-solid-state cells to manufacturers for testing.

Toyota is among a group of companies not looking to hedge their bets. The automaker, ignoring naysayers, aims to commercialize solid-state batteries by 2027 that it says will give an EV a range of 1,200 km on a single charge and allow 10-minute fast charging. It attributes its optimism to breakthroughs addressing durability issues. And for companies like Solid Power, it’s also solid-state or bust. Solid Power, which aims to commercialize a lithium battery with a proprietary sulfide-based solid electrolyte, has partnered with major automakers Ford and BMW. ProLogium Technology, which is also forging ahead with preparations for a solid-state battery rollout, claims that it will start delivering batteries this year that combine a ceramic oxide electrolyte with a lithium-free soft cathode (for energy density exceeding 500 Wh/kg). The company, which has teamed up with Mercedes-Benz, demonstrated confidence in its timetable by opening the world’s first giga-level solid-state lithium ceramic battery factory earlier this year in Taoyuan, Taiwan.

A Clean, Green Way to Recycle Solar Panels



Inside a shipping container in an industrial area of Venice, the Italian startup 9-Tech is taking a crack at a looming global problem: how to responsibly recycle the 54 million to 160 million tonnes of solar modules that are expected to reach the end of their productive lives by 2050. Recovering the materials won’t be easy. Solar panels are built to withstand any environment on Earth for 20 to 30 years, and even after sitting in the sun for three decades, the hardware is difficult to dismantle. In fact, most recycling facilities trash the silicon, silver, and copper—the most valuable but least accessible materials in old solar panels—and recover only the aluminum frames and glass panes.

The need for recycling will only grow as the world increasingly deploys solar power. More than 1.2 terawatts of solar power has already been deployed globally. Solar panels are currently being distributed at a rate of more than 400 gigawatts per year, and the rate is expected to increase to a whopping 3 TW per year by 2030, according to a literature analysis by researchers at the National Renewable Energy Laboratory (NREL).

In an attempt to stop a mountain of photovoltaic garbage from accumulating, researchers are pursuing better recycling methods. The most advanced methods proposed so far can recover at least 90 percent of the copper, silver, silicon, glass, and aluminum in a crystalline silicon PV module. But these processes are expensive and often involve toxic chemicals. No recycling method has proven to be as cheap as landfilling, and very few operate on an industrial scale, says Garvin Heath, principal environmental engineer at NREL, who manages a group of international experts assigned by the International Energy Agency to analyze PV sustainability.

The founders of 9-Tech say they have a better way. Their process is a noisy one involving a combustion furnace, an ultrasound bath, and mechanical sorting, the vibrations of which shake the floor of the modest freight container where they have been testing their operation for nearly two years. The company uses no toxic chemicals, releases no pollutants into the environment, and recovers up to 90 percent of the materials in a solar panel, says Francesco Miserocchi, chief technology officer at 9-Tech.

How to Recycle Solar Panels

Workers cut the inner layers into large sections in preparation for the oven.Luigi Avantaggiato

The company tailors its process to crystalline silicon solar panels, which make up 97 percent of the global PV market. The panels typically consist of an array of silicon wafers doped with boron and phosphorus, and topped with an antireflective coating of silicon nitride. Silver conductors are screen printed onto the wafer surface, and copper conductors are soldered onto the array in a grid pattern. To protect the materials from moisture and damage, manufacturers laminate the entire array in adhesive polymers—usually ethylene-vinyl acetate. Then they encase the laminated array in sheets of tempered glass, frame the whole thing in aluminum, seal the edges, and attach a junction box on the back.

When it’s time to recycle a panel, one of the most challenging steps is removing the polymers, which stick to everything. “It’s not just the edges or a couple of dots of glue. It’s an entire surface—several square feet—of polymer,” says Heath. The polymer can be burned off, but this releases carbon monoxide, hydrofluoric acid, and other harmful pollutants. Separating the silver conductors also proves challenging because they’re applied in a very thin layer–about 10 to 20 micrometers–that is strongly attached to the silicon. Removing them typically involves toxic reagents such as hydrofluoric acid, nitric acid, or sodium hydroxide.

The team at 9-Tech addresses these challenges in two ways. They recover the silver using ultrasound rather than toxic chemicals, and although they burn the polymers, they capture the pollutants emitted.

Layers of silicon and polymer are fed into a continuous combustion furnace, which heats the materials to over 400 °C, vaporizing the polymers. 9-Tech

The process at the company’s pilot plant starts with workers manually removing the aluminum frame, junction box, and tempered glass. This leaves a sandwich of polymers, silicon wafers, and metal conductors. Without the frame or glass, the sandwich layers bend, shattering the fragile silicon into small pieces. Workers crack the tempered glass and then send all the materials, which are mostly still in place because of the polymers, into a continuous combustion furnace. Heated to over 400 °C, the polymers vaporize, and a filter captures the pollutants. The system also captures the heat from the furnace and reuses it for energy efficiency.

As the remaining material exits the furnace, a roller mechanically strips out the copper. A series of sieves sort the broken bits of glass and silicon based on thickness. The silicon pieces, still laced with silver, are immersed in a bath of organic acid and treated with ultrasound to loosen the bonds between the elements. The ultrasound works by propagating sound waves into the acid bath, resulting in alternating high- and low-pressure cycles. If the waves are intense enough, they create cavitation bubbles that mechanically interact with the material, causing the silver to dislodge from the silicon, explains Pietrogiovanni Cerchier, CEO at 9-Tech.

Finally, workers remove the silicon fragments from the ultrasound bath with a mesh net. This leaves a fine silver dust in the solution, which can be recovered by filtration or centrifuge. All told, Cerchier says, 9-Tech’s pilot plant can recover 90 percent of the silver, 95 percent of the silicon, and 99 percent or more of the copper, aluminum, and glass from a PV module. What’s more, the material is considered highly pure, which increases the types of applications for which it can be reused.

The startup’s recycling process is more expensive than existing methods that recover only aluminum and glass. But the extraction of high-purity silicon, silver, and copper should offset the extra cost, Miserocchi says. Plus, it’s more efficient than mining for virgin elements. You can extract about 500 grams of silver from a tonne of solar panels, but only 165 grams of silver from a tonne of ore, he says. “A photovoltaic panel at the end of its life still has a lot to give,” says Miserocchi. “It can be considered a small mine of precious elements.”

Dozens of New Ways to Recycle PV Panels

The 9-Tech team will know more about the profitability of their method after they build a larger demonstration facility over the next 18 months. That plant, to be located in the same industrial district of Venice as the shipping container, will be able to handle up to 800 solar modules a day. Their pilot plant processes only about seven modules a day.

The company’s approach is one of many recycling methods for crystalline silicon PV panels in development. A comprehensive review published in April in the Journal of Cleaner Production identified dozens of other efforts globally, including thermal, chemical, mechanical, and optical approaches. The most common method involves grinding the silicon, metal, and polymer layers into small pieces, separating them by density, and recovering the silicon and metal with a thermal or chemical process. Other processes include laser irradiation, high-voltage pulses, optical sorting, pyrolysis, chemical solvents, etching, and delaminating with a hot knife.

Driving this innovation, in part, are regulations adopted by the European Union in 2012. The rules require all PV panel manufacturers in the EU to run take-back or recycling programs, or partner with other recycling schemes. As a result, Germany, which has the most solar power capacity in Europe, has one of the largest PV recycling systems in the world.

“A photovoltaic panel at the end of its life still has a lot to give,” says Miserocchi. “It can be considered a small mine of precious elements.”

But recycling is a high-volume business, and aside from catastrophic weather events that wipe out solar power stations, spent solar modules reach recyclers at a relative trickle. And then there’s the challenge of finding a second life for the materials after they are recovered—a supply chain that’s not well developed.

First Solar, a global PV manufacturer based in Tempe, Ariz., addressed both of these issues on a large scale by building an in-house recycling program with seven facilities in five countries. The company makes cadmium telluride thin-film solar panels that buyers can purchase with the recycling price built in. At the end of the panels’ lives, buyers send them back to First Solar for recycling into new products. The semiconductor material can be recycled up to 41 times, giving it a life-span of more than 1,200 years, according to the company. But the glass isn’t pure enough to be reused in solar modules, so the company plans to supply it to float-glass manufacturers for use in windows and doors.

The challenges with recycling have inspired researchers to rethink the way crystalline solar panels are made. For example, some manufacturers are trying to reduce or eliminate the difficult-to-recover silver, replacing it with other conductive metals. And a team at NREL demonstrated in February a way to eliminate polymers in PV panels by laser welding the glass panes instead, which may do a better job sealing out moisture. That technique may lend itself to perovskite solar modules, a promising technology that is particularly susceptible to moisture and corrosion.

“Recycling shouldn’t be the only strategy,” says Heath. People should consider alternative ways to repair or reuse solar panels to extend their lives before resorting to recycling, he says.

This Engineer’s Solar Panels Are Breaking Efficiency Records



When Yifeng Chen was a teenager in Shantou, China, in the early 2000s, he saw a TV program that amazed him. The show highlighted rooftop solar panels in Germany, explaining that the panels generated electricity to power the buildings and even earned the owners money by letting them sell extra energy back to the electricity company.

An incredulous Chen marveled at not only the technology but also the economics. A power authority would pay its customers?

It sounded like magic: useful and valuable electricity extracted from simple sunlight. The wonder of it all has fueled his dreams ever since.

In 2013 Chen earned a Ph.D. in photovoltaic sciences and technologies, and today he’s assistant vice president of technology at China’s Trina Solar, a Changzhou-based company that is one of the largest PV manufacturers in the world. He leads the company’s R&D group, whose efforts have set more than two dozen world records for solar power efficiency and output.

For Chen’s contributions to the science and technology of photovoltaic energy conversion, the IEEE member received the 2023 IEEE Stuart R. Wenham Young Professional Award from the IEEE Electron Devices Society.

“I was quite surprised and so grateful” to receive the Wenham Award, Chen says. “It’s a very high-level recognition, and there are so many deserving experts from around the world.”

Trina Solar’s push for more efficient hardware

Today’s commercial solar panels typically achieve about 20 percent efficiency: They can turn one-fifth of captured sunlight into electricity. Chen’s group is trying to make the panels more efficient.

The group is focusing on optimizing solar cell designs, including the passivated emitter and rear cell (PERC), which is the industry standard for commodity solar panels.

Invented in 1983, PERCs are used today in nearly 90 percent of solar panels on the market. They incorporate coatings on the front and back to capture sunlight more effectively and to avoid losing energy, both at the surfaces and as the sunlight travels through the cell. The coatings, known as passivation layers, are made from materials such as silicon nitride, silicon dioxide, and aluminum oxide. The layers keep negatively charged free electrons and positively charged electron holes apart, preventing them from combining at the surface of the solar cell and wasting energy.

Chen and his team have developed several ways to boost the performance of PERC panels, hitting a record of 24.5 percent efficiency in 2022. One of the technologies is a multilayer antireflective coating that helps solar panels trap more light. They also created extremely fine metallization fingers—narrow lines on solar cells’ surfaces—to collect and transport the electric current and help capture more sunlight. And they developed an advanced method for laying the strips of conductive metal that run across the solar cell, known as bus bars.

Experts predict the maximum efficiency of PERC technology will be reached soon, topping out at about 25 percent.

“So the question is: How do we get solar cells even more efficient?” Chen says.

During the past few years he and his group have been working on tunnel oxide passivated contact (TOPCon) technology. A TOPCon cell uses a thin layer of “tunneling oxide” insulating material—typically silicon dioxide—which is applied to the solar cell’s surface. Similar to the passivation layers on PERC cells, the tunnel oxide stops free electrons and electron holes from combining and wasting energy.

In 2022 Trina created a TOPCon-type panel with a record 25.5 percent efficiency, and two months ago the company announced it had achieved a record 740.6 watts for a mass-produced TOPCon solar module. The latter was the 26th record Trina set for solar power–related efficiencies and outputs.

To achieve that record-breaking performance for their TOPCon panels, Chen and his team optimized the company’s manufacturing processes including laser-induced firing, in which a laser heats part of the solar cell and creates bonds between the metal contacts and the silicon wafer. The resulting connections are stronger and better aligned, enhancing efficiency.

“We’re trying to keep improving things to trap just a little bit more sunlight,” Chen says. “Gaining 1 or 2 percent more efficiency is huge. These may sound like very tiny increases, but at scale these small improvements create a lot of value in terms of economics, sustainability, and value to society.”

As the efficiency of solar cells rises and prices drop, Chen says, he expects solar power to continue to grow around the world. China currently leads the world in installed solar power capacity, accounting for about 40 percent of global capacity. The United States is a distant second, with 12 percent, according to a 2023 Rystad Energy report. The report predicts that China’s 500 gigawatts of solar capacity in 2023 is likely to exceed 1 terawatt by 2026.

“I’m inspired by using science to create something useful for human beings, and then driven by the pursuit for excellence,” Chen says. “We can always learn something new to make that change, improve that piece of technology, and get just that little bit better.”

Trained by solar-power pioneers

Chen attended Sun Yat-sen University in Guangzhou, China, earning a bachelor’s degree in optics sciences and technologies in 2008. He stayed on to pursue a Ph.D. in photovoltaics sciences and technologies. His research was on high-efficiency solar cells made from wafer-based crystalline silicon. His adviser was Hui Shen, a leading PV professor and founder of the university’s Institute for Solar Energy Systems. Chen calls him “the first of three very important figures in my scientific career.”

In 2011 Chen spent a year as a Ph.D. student at Leibniz University Hannover, in Germany. There he studied under Pietro P. Altermatt, the second influential figure in his career.

Altermatt—a prominent silicon solar-cell expert who would later become principal scientist at Trina—advised Chen on his computational techniques for modeling and analyzing the behavior of 2D and 3D solar cells. The models play a key role in designing solar cells to optimize their output.

“Gaining 1 or 2 percent more efficiency is huge. These may sound like very tiny increases, but at scale, these small improvements create a lot of value in terms of economics, sustainability, and value to society.”

“Dr. Altermatt changed how I look at things,” Chen says. “In Germany, they really focus on device physics.”

After completing his Ph.D., Chen became a technical assistant at Trina, where he met the third highly influential person in his career: Pierre Verlinden, a pioneering photovoltaic researcher who was the company’s chief scientist.

At Trina, Chen quickly ascended through R&D roles. He has been the company’s assistant vice president of technology since 2023.

IEEE’s “treasure” trove of research

Chen joined IEEE as a student because he wanted to attend the IEEE Photovoltaic Specialists Conference, the longest-running event dedicated to photovoltaics, solar cells, and solar power.

The membership was particularly beneficial during his Ph.D. studies, he says, because he used the IEEE Xplore Digital Library to access archival papers.

“My work has certainly been inspired by papers I found via IEEE,” Chen says. “Plus, you end up clicking around and reading other work that isn’t related to your field but is so interesting.

“The publication repository is a treasure. It’s eye-opening to see what’s going on inside and outside of your industry, with new discoveries happening all the time.”

Of the many oddities you can buy from Aliexpress, some of the weirdest are the recreations of retro computer systems in semi-modern designs. We're most intimately familiar with the Book 8088, a recreation of the original 1981 IBM PC inside a chunky clamshell laptop. The people behind the Book 8088 are also responsible for the Hand386, which is a bit like a late-80s PC stuck inside an old Palm Pilot or Blackberry, and a second revision of the Book 8088 with more built-in ports and a VGA-capable graphics adapter installed instead of a basic CGA adapter.

Whoever is selling these systems is now back with the Pocket 386, which combines Hand386-style internals with a clamshell design similar to the Book 8088. The result is the kind of IBM-compatible system that would have been common during the Windows 3.1 era, when MS-DOS still dominated (especially for games) but Windows was on the upswing.

The Biden administration will ban all sales of Kaspersky antivirus software in the US starting in July, according to reporting from Reuters and a filing from the US Department of Commerce (PDF).

The US believes that security software made by Moscow-based Kaspersky Lab represents a national security risk and that the Russian government could use Kaspersky's software to install malware, block other security updates, and "collect and weaponize the personal information of Americans," said US Commerce Secretary Gina Raimondo.

“When you think about national security, you may think about guns and tanks and missiles,” said Raimondo during a press briefing, as reported by Wired. “But the truth is, increasingly, it's about technology, and it's about dual-use technology, and it's about data.”

Often times, when I am researching something about computers or coding that has been around a very long while, I will come across a document on a university website that tells me more about that thing than any Wikipedia page or archive ever could.

It's usually a PDF, though sometimes a plaintext file, on a .edu subdirectory that starts with a username preceded by a tilde (~) character. This is typically a document that a professor, faced with the same questions semester after semester, has put together to save the most time possible and get back to their work. I recently found such a document inside Princeton University's astrophysics department: "An Introduction to the X Window System," written by Robert Lupton.

X Window System, which turned 40 years old earlier this week, was something you had to know how to use to work with space-facing instruments back in the early 1980s, when VT100s, VAX-11/750s, and Sun Microsystems boxes would share space at college computer labs. As the member of the AstroPhysical Sciences Department at Princeton who knew the most about computers back then, it fell to Lupton to fix things and take questions.

Apple Intelligence and other features won’t launch in the EU this year

Three major features in iOS 18 and macOS Sequoia will not be available to European users this fall, Apple says. They include iPhone screen mirroring on the Mac, SharePlay screen sharing, and the entire Apple Intelligence suite of generative AI features.

In a statement sent to Financial Times, The Verge, and others, Apple says this decision is related to the European Union's Digital Markets Act (DMA). Here's the full statement, which was attributed to Apple spokesperson Fred Sainz:

Two weeks ago, Apple unveiled hundreds of new features that we are excited to bring to our users around the world. We are highly motivated to make these technologies accessible to all users. However, due to the regulatory uncertainties brought about by the Digital Markets Act (DMA), we do not believe that we will be able to roll out three of these features — iPhone Mirroring, SharePlay Screen Sharing enhancements, and Apple Intelligence — to our EU users this year.

Specifically, we are concerned that the interoperability requirements of the DMA could force us to compromise the integrity of our products in ways that risk user privacy and data security. We are committed to collaborating with the European Commission in an attempt to find a solution that would enable us to deliver these features to our EU customers without compromising their safety.

It is unclear from Apple's statement precisely which aspects of the DMA may have led to this decision. It could be that Apple is concerned that it would be required to give competitors like Microsoft or Google access to user data collected for Apple Intelligence features and beyond, but we're not sure.

Win+C, Windows’ most cursed keyboard shortcut, is getting retired again

A rendering of the Copilot button.

Microsoft is all-in on its Copilot+ PC push right now, but the fact is that they'll be an extremely small minority among the PC install base for the foreseeable future. The program's stringent hardware requirements—16GB of RAM, at least 256GB of storage, and a fast neural processing unit (NPU)—disqualify all but new PCs, keeping features like Recall from running on all current Windows 11 PCs.

But the Copilot chatbot remains supported on all Windows 11 PCs (and most Windows 10 PCs), and a change Microsoft has made to recent Windows 11 Insider Preview builds is actually making the feature less useful and accessible than it is in the current publicly available versions of Windows. Copilot is being changed from a persistent sidebar into an app window that can be resized, minimized, and pinned and unpinned from the taskbar, just like any other app. But at least as of this writing, this version of Copilot can no longer adjust Windows' settings, and it's no longer possible to call it up with the Windows+C keyboard shortcut. Only newer keyboards with the dedicated Copilot key will have an easy built-in keyboard shortcut for summoning Copilot.

If Microsoft keeps these changes intact, they'll hit Windows 11 PCs when the 24H2 update is released to the general public later this year; the changes are already present on Copilot+ PCs, which are running a version of Window 11 24H2 out of the box.

Big tech companies are still trying to rally workers back into physical offices, and many workers are still not having it. Based on a recent report, computer-maker Dell has stumbled even more than most.

Dell announced a new return-to-office initiative earlier this year. In the new plan, workers had to classify themselves as remote or hybrid.

Those who classified themselves as hybrid are subject to a tracking system that ensures they are in a physical office 39 days a quarter, which works out to close to three days per work week.

The Google Pay app is dead

Google has killed off the Google Pay app. 9to5Google reports Google's old payments app stopped working recently, following shutdown plans that were announced in February. Google is shutting down the Google Pay app in the US, while in-store NFC payments seem to still be branded "Google Pay." Remember, this is Google's dysfunctional payments division, so all that's happening is Google Payment app No. 3 (Google Pay) is being shut down in favor of Google Payment app No. 4 (Google Wallet). The shutdown caps off the implosion of Google's payments division after a lot of poor decisions and failed product launches.

Google's NFC payment journey started in 2011 with Google Wallet (apps No. 1 and No. 4 are both called Google Wallet). In 2011, Google was a technology trailblazer and basically popularized the idea of paying for something with your phone in many regions (with the notable exception of Japan). Google shipped the first non-Japanese phones with the feature, fought carriers trying to stop phone payments from happening, and begged stores to get new, compatible terminals. Google's entire project was blown away when Apple Pay launched in 2014, and Google's response was its second payment app, Android Pay, in 2015. This copied much of Apple's setup, like sending payment tokens instead of the actual credit card number. Google Pay was a rebrand of this setup and arrived in 2018.

The 2018 version of Google Pay was a continuation of the Android Pay codebase, which was a continuation of the Google Wallet codebase. Despite all the rebrands, Google's payment apps were an evolution, and none of the previous apps were really "shut down"—they were in-place upgrades. Everything changed in 2021 when a new version of Google Pay was launched, which is when Google's payment division started to go off the rails.

These are all the devices compatible with iOS 18 and iPadOS 18

These are all the devices compatible with iOS 18 and iPadOS 18

Apple's new iOS 18 and iPadOS 18 updates are mostly good news for users of older Apple devices—with the exception of 2018's sixth-generation iPad, the new updates will run on all the same hardware that can run iOS 17 and iPadOS 17.

For iPhones, that will cover everything from the iPhone XR/XS and newer, including the second-gen iPhone SE; the seventh-gen iPad and newer; the third-gen iPad Air and newer; the fifth-gen iPad mini and newer; all 11-inch iPad Pros; and the third-gen 12.9-inch iPad Pro and later. Here are the full support lists:

It's a bit odd that the seventh-gen iPad makes the cutoff while the sixth-gen model does not, given that both use the same Apple A10 processor. But the seventh-gen iPad has 3GB of RAM instead of 2GB. This is the same amount as the third-gen iPad Air and fifth-gen iPad mini—apparently that extra gigabyte is crucial for running iPadOS 18's new features.

Apple integrates ChatGPT into Siri, iOS, and macOS

Reports of Apple signing a deal with OpenAI are true: ChatGPT is coming to your Apple gear.

First up is Siri, which can tap into ChatGPT to answer voice questions. If Siri thinks ChatGPT can help answer your question, you'll get a pop-up permission box asking if you want to send your question to the chatbot. The response will come back in a window indicating that the information came from an outside source. This is the same way Siri treats a search engine (namely, Google), so how exactly Siri draws a line between ChatGPT and a search engine will be interesting. In Apple's lone example, there was a "help" intent, with the input saying to "help me plan a five-course meal" given certain ingredient limitations. That sort of ultra-specific input is something you can't do with a traditional search engine.

Siri can also send photos to ChatGPT. In Apple's example, the user snapped a picture of a wooden deck and asked Siri about decorating options. It sounds like the standard generative AI summary features will be here, too, with Apple SVP of Software Engineering Craig Federighi mentioning that "you can also ask questions about your documents, presentations, or PDFs."

Here are all the Intel and Apple Silicon Macs that will run macOS 15 Sequoia

Most owners of aging Intel Macs got a bit of a reprieve today when Apple announced macOS 15 Sequoia—this new macOS release will run on the vast majority of the hardware that can currently run macOS 14 Sonoma. Intel Macs released between December of 2017 and 2020 are mostly eligible for the new update, though newer models with Apple Silicon chips will be needed to support some of the new features.

Apple's full support list for Sequoia is as follows:

Generally, all of these Macs include Apple's T2 chip, a co-processor installed in late-model Intel Macs that bridged the gap between the Intel and Apple Silicon eras. There are two exceptions. The biggest is the 2018 MacBook Air, which did come with an Apple T2 but also shipped with a weak dual-core processor and integrated GPU that Apple has apparently decided aren't up to the task of handling Sequoia. The other is the 2019 iMac, which for whatever reason shipped without a T2. Apple says the iPhone mirroring feature does require the T2 chip, so it presumably won't work on the 2019 iMac.
