Every so often, you live through a year that you know you’re going to remember. Sometimes it’s because of a personal milestone. Other times it’s because of noteworthy events that affected all of us in one way or another. And in some years, it’s because we were all surprised by unanticipated and rapid technological advances.
2023 definitely will be a year that will be remembered. On the tech side, the biggest story was AI, due in no small part to rapid advances in large language models. We had news about space flight, hackers, operating systems, and even music players.
Read on to find out which stories resonated the most with our readers throughout the year.
20. The Ars guide to time travel in the movies
Depending on the screenwriting, time travel can be one of the best plot devices in a movie… or one of the most confusing, if done poorly. As we have come to better understand the nature of time, Hollywood has begun producing more flicks that use it as part of the story.
Our ace science reporter Jennifer Ouellette happens to be married to a physicist with his own subreddit, so we decided to turn them loose on the topic of time travel and the movies to see which films had the best combination of entertainment and scientific rigor. Read on to find out where Bill & Ted’s Excellent Adventure, 12 Monkeys, and Hot Tub Time Machine ended up.
19. The IBM mainframe: How it runs and why it survives
Largely considered relics of a bygone computing era, over 10,000 mainframe computers are still used today. Used primarily by Fortune 500 companies, most of these mainframes are sold by IBM. With a lineage dating back to technological advancements of the 1950s, these computers still excel with some high-volume use cases, especially those involving banking.
There used to be a bunch of companies in the mainframe game, but Rand, GE, NEC, Honeywell, and just about everyone else either no longer exists or is no longer building mainframes. IBM is now the only mainframe manufacturer that matters, so check out the story to learn why some companies still do some of their computing on mainframes instead of in the cloud.
18. macOS 14 Sonoma: The Ars Technica review
I cannot remember a top-20 list that didn’t include a macOS review. But this may be the furthest down the list it has ever appeared, and
This is due in no small part to how major OS updates come out like clockwork once a year, even when there are no major new features to excite users. These days, OS updates can be met with grumbling due to unnecessary UI changes and hardware obsolescence. Sonoma is another “low key” update, as Andrew Cunningham described it in his usual, comprehensive review. Call it “Ventura plus” or whatever you like—Sonoma is business as usual.
17. Android app from China executed 0-day exploit on millions of devices
Ah, it’s our first 0-day of the 2023 countdown. This one primarily affected users of third-party app stores and involved the Pinduoduo app, downloaded millions of times. As Dan Goodin described it:
“[T]he malicious Pinduoduo app includes functionality allowing for the app to be installed covertly with no ability to be uninstalled, falsely inflating the number of Pinduoduo daily active users and monthly active users, uninstalling competitor apps, stealing user privacy data, and evading various privacy compliance regulations.”
Yikes.
The versions of the app in Google Play and Apple’s App Store did not contain the backdoor.
