Enlarge / Acer continued selling laptops, like these Chromebooks, in Russia after saying it suspended business there, Reuters reports.

Per a report by Reuters on Thursday, Acer said it sold monitors in Russia after publicly declaring that it would suspend business there due to the Russia-Ukraine war. In Reuters' report, Acer claimed it only sold a "limited number of displays and accessories" for "civilian daily use." Additionally, Reuters reported that Acer sold laptops in Russia after saying it wouldn't.

On April 8, 2022, Acer, like many tech companies (see: HP, Dell, Microsoft, Intel, Nvidia, etc.), said it would no longer do business in Russia for the foreseeable future.

"Acer strictly adheres to applicable international trade laws and regulations and is closely monitoring the conflict between Russia and Ukraine. Due to recent developments, Acer has decided to suspend its business in Russia," the company's statement said at the time.

On Wednesday, two German researchers, Sophie Jentzsch and Kristian Kersting, released a paper that examines the ability of OpenAI's ChatGPT-3.5 to understand and generate humor. In particular, they discovered that ChatGPT's knowledge of jokes is fairly limited: During a test run, 90 percent of 1,008 generations were the same 25 jokes, leading them to conclude that the responses were likely learned and memorized during the AI model's training rather than being newly generated.

The two researchers, associated with the Institute for Software Technology, German Aerospace Center (DLR), and Technical University Darmstadt, explored the nuances of humor found within ChatGPT's 3.5 version (not the newer GPT-4 version) through a series of experiments focusing on joke generation, explanation, and detection. They conducted these experiments by prompting ChatGPT without having access to the model's inner workings or data set.

"To test how rich the variety of ChatGPT’s jokes is, we asked it to tell a joke a thousand times," they write. "All responses were grammatically correct. Almost all outputs contained exactly one joke. Only the prompt, 'Do you know any good jokes?' provoked multiple jokes, leading to 1,008 responded jokes in total. Besides that, the variation of prompts did have any noticeable effect."

Twitter co-founder Evan "Ev" Williams has broken his silence and joined other co-founders in expressing his dismay at how Elon Musk is running the platform.

In his first public remarks on Musk's leadership since Musk's Twitter takeover, Williams told Bloomberg's "The Circuit" yesterday that after Musk's purchase went through, he felt "sad."

Ever since, he hasn't been encouraged by developments at Twitter. The company's ongoing financial struggles include most recently recording a five-week period from April to May, where its advertising revenue dropped by 59 percent, compared to ad revenue at the same time last year.

All of the organisms we can see around us—the plants, animals, and fungi—are eukaryotes composed of complex cells. Their cells have many internal structures enclosed in membranes, which keep things like energy production separated from genetic material, and so on. Even the single-celled organisms on this branch of the tree of life often have membrane-covered structures that they move and rearrange for feeding.

Some of that membrane flexibility comes courtesy of steroids. In multicellular eukaryotes, steroids perform various functions; among other things, they’re used as signaling molecules, like estrogen and testosterone. But all eukaryotes insert various steroids into their membranes, increasing their fluidity and altering their curvature. So the evolution of an elaborate steroid metabolism may have been critical to enabling complex life.

Now, researchers have traced the origin of eukaryotic steroids almost a billion years further back in time. The results suggest that many branches of the eukaryotic family tree once made early versions of steroids. But our branch evolved the ability to produce more elaborate ones—which may have helped us outcompete our relatives.

An antitrust-based lawsuit accusing Amazon and Apple of colluding to keep Apple products priced higher in Amazon's store is moving forward after a judge declined to dismiss the case on the companies' motions. (credit: Getty Images)

A federal judge has rejected Apple's and Amazon's motions to wholly dismiss a consumer antitrust lawsuit, one that accuses the tech giants of colluding to eliminate all but the highest-price Apple products in Amazon's online store.

Writing in Seattle (PDF), Judge John C. Coughenour noted that Apple and Amazon do not dispute the existence of their agreement, which was publicly touted by the companies in November 2018. Nor do they argue that it had an "effect on interstate commerce," as required by a lawsuit making a complaint under the Sherman Act. The issues pushed in the defendants' motion for dismissal is whether the Global Tenets Agreement (GTA) signed by the companies has an impact on "a relevant market" and whether it "imposes an unreasonable restraint of trade."

Coughenour dismissed one aspect of the plaintiff's lawsuit. He disagreed with Apple's and Amazon's positioning of themselves as competing to sell Apple products "at a horizontal level." Instead, they are, under their GTA, "vertically situated" as a manufacturer and distributor. But, given the "complex nature of the business relationships between the parties," Coughenour wrote, and the fact that the plaintiffs agree that not all resellers of Apple products were removed from Amazon's marketplace, a "per se" finding of antitrust violation could not be sustained.

Large language models (LLMs) like ChatGPT and Google Bard can provide some decent answers to certain types of questions, but these computers are ironically pretty bad at computing stuff. Google has a new solution to try to get language models to do simple tasks, like math, correctly: have the AI write a program. Google says that now when you ask Bard a "computational" task like math or string manipulation, instead of showing the output of the language model, that language model will instead write a program, execute that program, and then show the output of that program to the user as an answer.

Google's blog post provides the example input of "Reverse the word 'Lollipop' for me." ChatGPT flubs this question and provides the incorrect answer "pillopoL," because language models see the world in chunks of words, or "tokens," and they just aren't good at this. Here is Bard's example output:

It gets the output correct as "popilloL," but more interesting is that it also includes the python code it wrote to answer the question. That's neat for programming-minded people to see under the hood, but wow is that probably the scariest output ever for The Normals. It's also not particularly relevant? Imagine if Gmail showed you a block of code when you just asked it to fetch email. It's weird. Just do the job you were asked to do, Bard.

In November 2019, Tesla CEO Elon Musk stepped onto a stage in California to launch a new kind of EV: the Cybertruck, an angular cyberpunk-styled pickup with bodywork made of brushed stainless steel and “unbreakable” glass. What happened next has entered into public relations folklore. Under the glare of the cameras, the demo truck’s windows smashed not once, but twice during a demonstration of their strength. Musk first swore, then joked: “There’s room for improvement.” That off-the-cuff remark could have been a fitting mantra for the entire project.

Not that this faltering start has deterred Tesla’s devoted fans, of course. Since then, an estimated 1.8 million customers have put down their $100 deposits to reserve a Cybertruck. The vehicle was supposed to start rolling off production lines in 2021. But two years on, the trucks still haven’t been delivered, and for most customers, they won’t be until 2024 at the earliest.
