“Earth’s magnetic environment is filled with a symphony of sound that we cannot hear,” NASA wrote this month. When solar winds approach earth, “it causes the magnetic field lines and plasma around Earth to vibrate like the plucked strings of a harp, producing ultralow-frequency waves… a cacophonous operetta portraying the dramatic relationship between Earth and the Sun.”

So NASA is now announcing “a new NASA-funded citizen science project called HARP — or Heliophysics Audified: Resonances in Plasmas ” that has “turned those once-unheard waves into audible whistles, crunches, and whooshes…” Or, as the Washington Post puts it, “NASA wants your help listening in on the universe.”

From NASA’s news release:

In 2007, NASA launched five satellites to fly through Earth’s magnetic “harp” — its magnetosphere — as part of the THEMIS mission (Time History of Events and Macroscale Interactions during Substorms). Since then, THEMIS has been gathering a bounty of information about plasma waves across Earth’s magnetosphere. “THEMIS can sample the whole harp,” said Michael Hartinger, a heliophysicist at the Space Science Institute in Colorado. “And it’s been out there a long time, so it has collected a lot of data.”

The frequencies of the waves THEMIS measures are too low for our ears to hear, however. So the HARP team sped them up to convert them to sound waves. By using an interactive tool developed by the team, you can listen to these waves and pick out interesting features you hear in the sounds… Preliminary investigations with HARP have already started revealing unexpected features, such as what the team calls a “reverse harp” — frequencies changing in the opposite way than what scientists anticipated…

“Data sonification provides human beings with an opportunity to appreciate the naturally occurring music of the cosmos,” said Robert Alexander, a HARP team member from Auralab Technologies in Michigan. “We’re hearing sounds that are literally out of this world, and for me that’s the next best thing to floating in a spacesuit.”

To start exploring these sounds, visit the HARP website.

“Think listening to years’ worth of wave patterns is a job for artificial intelligence? Think again,” writes the Washington Post.
In a news release, HARP team member Martin Archer of Imperial College London says humans are often better at listening than machines. “The human sense of hearing is an amazing tool,” Archer says. “We’re essentially trained from birth to recognize patterns and pick out different sound sources. We can innately do some pretty crazy analysis that outperforms even some of our most advanced computer algorithms.”

“Since the pandemic began, Lyft employees have been able to work remotely,” notes the New York Times, “logging into videoconferences from their homes and dispersing across the country like many other tech workers. Last year, the company made that policy official, telling staff that work would be ‘fully flexible’ and subleasing floors of its offices in San Francisco and elsewhere.”

No longer. On Friday, David Risher, the company’s new chief executive, told employees in an all-hands meeting that they would be required to come back into the office at least three days a week, starting this fall. [Although the Times adds later that “People will be allowed to work remotely for one month each year, and those living far from offices would not be required to come in.”]

It was one of the first major changes he has made at the struggling ride-hailing company since starting this month, and it came just a day after he laid off 26 percent of Lyft’s work force.

“Things just move faster when you’re face to face,” Mr. Risher said in an interview. Remote work in the tech industry, he said, had come at a cost, leading to isolation and eroding culture. “There’s a real feeling of satisfaction that comes from working together at a whiteboard on a problem.”

The decision, combined with the layoffs and other changes, signals the beginning of a new chapter at Lyft. It could also be an indication that some tech companies — particularly firms that are struggling — may be changing their minds on flexibility about where employees work. Nudges toward working in the office could soon turn into demands, as they have at companies like Disney and Apple…
Lyft also planned to tell employees that it would reduce their stock grants this year, according to a person familiar with the decision.

Risher “said the cost savings from the layoffs would go toward lower prices for riders and higher earnings for drivers,” the Times adds, noting that last month Lyft’s two founders said they’d step down after disappointing financial results. (Lyft’s stock price closed Friday at $10.25 — down from a peak of $78.)

Bob Sutton, a Stanford professor and organizational psychologist, suggests another possible motivation to the Times: executives worried about financial stress “feel compelled to increase their own illusion of control.”

Earlier this week TechCrunch reported that just like Stability AI, startup Hugging Face “has released an open source alternative to OpenAI’s viral AI-powered chabot, ChatGPT, dubbed HuggingChat.”

Available to test through a web interface and to integrate with existing apps and services via Hugging Face’s API, HuggingChat can handle many of the tasks ChatGPT can, like writing code, drafting emails and composing rap lyrics. The AI model driving HuggingChat was developed by Open Assistant, a project organized by LAION — the German nonprofit responsible for creating the dataset with which Stable Diffusion, the text-to-image AI model, was trained.

Open Assistant aims to replicate ChatGPT, but the group — made up mostly of volunteers — has broader ambitions than that. “We want to build the assistant of the future, able to not only write email and cover letters, but do meaningful work, use APIs, dynamically research information and much more, with the ability to be personalized and extended by anyone,” Open Assistant writes on its GitHub page. “And we want to do this in a way that is open and accessible, which means we must not only build a great assistant, but also make it small and efficient enough to run on consumer hardware…”

HuggingChat joins a growing family of open source alternatives to ChatGPT. Just last week, Stability AI released StableLM, a set of models that can generate code and text given basic instructions.

Linux Magazine argues that System76’s Pop!_OS offers “something rare: a commercial distribution that was integrated into the hardware, with utilities designed specifically for System76 computers and keyboards.”

The only other example of an integrated commercial distro of which I am aware is Purism, a company in the same niche… With hardware and software coming from the same source — what business calls vertical integration — distributions like System76/Pop!_OS offer Linux users their first experiences with what Windows and macOS users have always enjoyed — to say nothing of the closest they can currently get to open hardware. Could Linux be finally becoming mainstream at last?

They interviewed System76 CEO Carl Richell (along with a marketing director and media relations manager), who remembered how System76 was actually founded in Carl’s basement around 2005:

He wanted to show the world how far Linux and open source software had come by delivering it preinstalled on high-quality computers backed by caring, knowledgeable customer support. Carl felt that making Linux computers that highlight the work of the community would be a great way to introduce the broader public to open source technology and its potential…

LM: What other hardware might System76 offer in the future?
S76: We are in the research and development process of designing our own in-house laptop. We’ll eventually refresh our Meerkat mini desktop with a new Thelio-style aesthetic. That project will start sometime after our first in-house laptops start shipping. [In addition,] Launch keyboards and the System76 Keyboard Configurator work on macOS and Windows! We’ve also prepared ISO layouts for most Launch models but don’t have a time frame for release.
LM: What are you willing to say at this point about the company’s future directions?

S76: We’re developing COSMIC DE — a desktop environment written in Rust — as well as a prototype for an open hardware laptop manufactured in-house. Finally, Nebula, a line of computer cases based on Thelio desktops will be arriving in the coming months.
My favorite line from the interview? “Seeing a flat sheet of aluminum transformed into a beautiful desktop is strikingly rewarding.”
