I spent nearly 20 minutes this morning trying to be a good operating system, but you know what? People expect too much of their computers.

I worked hard to rotate processes through CPU slots, I was speedy to respond to I/O requests, and I didn't even let memory pages get written to disk. But the user—some jerk that I'm guessing keeps 32 shopping tabs open during work—kept rage-quitting as processes slid in attrition from bright green to red to "red with a frozen face emoji." It made me want to get four more cores or potentially just kill a process out of spite. If they were a writer, like me, I'd kill the sandboxed tab with their blog editor open. Learn to focus, scribe!

You're the OS! is a browser game that combines stress, higher-level computer design appreciation, and panic-clicking exercise. Creator Pier-Luc Brault says specifically that the game "has not been created with education in mind," but it might introduce people to principles like process scheduling and memory swapping—"as long as it is made clear that it is not an exact depiction." Brault, a computer science teacher himself, writes that they may use the game to teach about cores, RAM shortages, and the like.

On Friday afternoon, I popped out of the house to run a quick errand. This week's press fleet car is a Hyundai Ioniq 5, a boxy, angular, and efficient electric vehicle. I never quite made it to my intended destination, though; a very slightly misjudged corner—at low speed—saw me clip the curb with the back right wheel, resulting in a dime-sized hole in the sidewall and a frustrating couple of hours. Needless to say, there is no spare tire in an Ioniq 5, nor a can of get-you-home foam, not that it would have helped in this instance. But I can't help thinking all that stress could have been avoided if the car used smaller wheels and higher profile tires.

Of all the current automotive trends, the ever-increasing size of wheels and tires may be my least favorite. If you're middle-aged, you've probably been driving for a couple of decades now, during which time smaller wheel sizes have been disappearing even faster than the honey bees. Just try finding good 14-inch tires for an older Miata, for example. Or even 15s.

The increasing popularity of crossovers and SUVs is largely to blame, though not entirely. So, too, is the move to battery electric vehicles, which is ironic considering that increasing wheel size very clearly hurts efficiency and range, the two main considerations for many EV buyers.

Some planets cannot hold on to their atmospheres. It's thought that most of whatever atmosphere Mars may have had was annihilated by the solar wind billions of years ago, even as Earth and Venus held on to theirs. But there are planets that orbit so close to their star that atmospheric loss is inevitable. With at least one of them, we’ve learned that it is also unpredictable.

Exoplanet Au Mic b is that planet. It orbits the young, hot, and temperamental red dwarf star Au Microscopii (Au Mic), which is only 23 million years old—nothing compared to our 4-billion-year-old sun. NASA’s Hubble Space Telescope caught this scorched world losing a portion of its atmosphere.

When a team of scientists from the NASA Goddard Space Flight Center, Dartmouth College, the University of California at Santa Cruz, and other institutions analyzed the Hubble observations, they were confused by the planet’s erratic behavior. There would be evidence of atmospheric loss in some of the data, then suddenly none at all. It was unpredictable.

Amazon senior vice president of devices and services David Limp will be leaving the company "before the end of the year," according to an Amazon spokesperson speaking to The Wall Street Journal. Limp has been with the company since 2010 and has overseen the development of major Amazon projects like the Echo smart speakers, the Alexa voice assistant, the Fire tablets and Fire TV devices, and the Amazon Appstore.

Amazon's first Kindle e-readers pre-date Limp's tenure, but the company's products since then have all followed the same basic formula: to drive more sales on Amazon. Hardware like the Fire tablets, Fire TV sticks, and Echo smart speakers are essentially sold at cost, with the hopes that they'll generate revenue once they're in users' homes.

The problem with that strategy is that even phenomenally successful products can fail if people use them in ways that don't make money for Amazon. That's the story of the Echo smart speaker and Alexa voice assistant, which as of late 2022 had reportedly lost Amazon some $10 billion because people mainly use Alexa to play music and check the weather and not to spend money.

Astra is running out of money.

It's been a year since Astra shelved its first orbital-class rocket after just two successful launches in seven flights. Chris Kemp, Astra's founder and CEO, last year unveiled a new rocket design he said would be more reliable and capable of carrying heavier cargo into orbit.

A year later, the development of Astra's new launch vehicle—named Rocket 4—appears to have slowed to a crawl. Astra has outfitted a new production line for Rocket 4 at the company's headquarters in Alameda, California, but the company doesn't have enough money to move forward on the program as quickly as it would like.

A Houston-based company that is one of several US firms building private lunar landers, Intuitive Machines, says its three-meter-tall Nova-C lander is finally ready to take to the skies.

"Our Nova-C lander is completely built," said Steve Altemus, cofounder and chief executive of Intuitive Machines, in an earnings call on Monday. "We will deliver a lunar lander ready to go in September."

Intuitive Machines is competing with other US companies, including Astrobotic and Firefly, for NASA-funded missions to deliver science experiments and other payloads to the surface of the Moon. Intuitive Machines and Astrobotic were formally awarded the first of these "Commercial Lunar Payload Services" contracts in May 2019. Each of the companies is running a couple of years behind schedule in producing their landers, however.
