But it gets worse: "The new-music market is actually shrinking. All the growth in the market is coming from old songs. The most popular new tracks now regularly account for less than 5 percent of total streams. That rate was twice as high just three years ago Adding to the nightmare, dead musicians are now coming back to life in virtual form — via holograms and 'deepfake' music — making it all the harder for young, living artists to compete in the marketplace.

The radio stations will play only songs that fit the dominant formulas, which haven't changed much in decades. The algorithms curating so much of our new music are even worse. Music algorithms are designed to be feedback loops , ensuring that the promoted new songs are virtually identical to your favorite old songs. Anything that genuinely breaks the mold is excluded from consideration almost as a rule.

That's actually how the current system has been designed to work. Even the music genres famous for shaking up the world — rock or jazz or hip-hop — face this same deadening industry mindset. I love jazz, but many of the radio stations focused on that genre play songs that sound almost the same as what they featured 10 or 20 years ago. In many instances, they actually are the same songs.

This state of affairs is not inevitable. A lot of musicians around the world — especially in Los Angeles and London — are conducting a bold dialogue between jazz and other contemporary styles.

They are even bringing jazz back as dance music. But the songs they release sound dangerously different from older jazz, and are thus excluded from many radio stations for that same reason. The very boldness with which they embrace the future becomes the reason they get rejected by the gatekeepers.

A country record needs to sound a certain way to get played on most country radio stations or playlists, and the sound those DJs and algorithms are looking for dates back to the prior century. And don't even get me started on the classical-music industry, which works hard to avoid showcasing the creativity of the current generation.

We are living in an amazing era of classical composition, with one tiny problem: The institutions controlling the genre don't want you to hear it. The problem isn't a lack of good new music. It's an institutional failure to discover and nurture it. So while the author acknowledges that "The fear of copyright lawsuits has made many in the industry deathly afraid of listening to unsolicited demo recordings," far deeper than that is the problem that, "The people running the music industry have lost confidence in new music.

Songs can go viral nowadays without the entertainment industry even noticing until it has already happened. That will be how this story ends: not with the marginalization of new music, but with something radical emerging from an unexpected place That's what gives me solace The decision makers controlling our music institutions have lost the thread. We're lucky that the music is too powerful for them to kill. A California newspaper covers " pleas" to the state's governor to delay the closure of a nuclear power plant : On Thursday, Dr.

Steven Chu, former U. Secretary of Energy under the Obama administration and a Nobel laureate, and more than 79 scientists, academics and entrepreneurs sent a letter to [California governor] Newsom urging him to find a way to keep the plant open because of the necessary carbon-free, clean electricity it provides to the state's electricity grid. The letter was sent by the nonprofit foundation Save Clean Energy , which was organized primarily to protest the closure of the nuclear power plant The letter details how Diablo Canyon is critical to the state's clean energy goals, which the state is legally mandated to meet, and how it seems unlikely the state will be able to meet those goals with the plant's current scheduled decommissioning beginning in November , when the first of its two Nuclear Regulatory Licenses expires The movement to keep Diablo Canyon nuclear power plant open has recently gained new traction after a Stanford and Massachusetts Institute of Technology report released in November claimed operating the plant for 10 years beyond its expected closure would significantly help the state meet its clean energy goals.

In a statement sent to The Tribune in December , a spokesperson for Newsom indicated the governor has no intention of delaying the closure of Diablo Canyon. The pathway is through diverse renewable energy sources, expanded energy storage and grid climate resiliency," Newsom spokesperson Erin Mellon wrote in an email to The Tribune.

People who direct audiobooks, people who edit audiobooks, people who check audiobook narration for word-for-word perfection against the manuscript Similarly, in audiobook narrator Hillary Huber's view, the negatives of AI outweigh any positives. She places "loss of livelihoods, loss of integrity in storytelling, and loss of personal connection" high on her list of concerns.

Do you really think [AI company] Speechki is going to pass their savings on to the listener? Listeners make choices about what to spend money on, and they have a right to demand clear labeling of robot voices, as do authors Industry statistics illustrate the gulf between the number of audiobooks that get to market and the number that could potentially be recorded. According to the most recent data from the Audio Publishers Association, more than 71, audiobooks were published in Though that number marks an industry high, it's still only a fraction of the number of print books published in Despite AI narration's potential to help grow the audiobook sector, its emergence is "creating an existential crisis for our narrator community," Lawrence said.

And as a community, we fully believe that what we do is art. Whether I'm out of a job or not, I would be devastated that the art that I care so deeply about is so horribly compromised. Although anti-air travel campaigners believe ghost flights are a widespread issue that airlines don't publicly disclose, Lufthansa is so far the only airline to go public about its own figures Lufthansa's own chief executive, Carsten Spohr [said] the journeys were "empty, unnecessary flights just to secure our landing and takeoff rights.

A Greenpeace analysis indicates that if Lufthansa's practice of operating no-passenger flights were replicated equally across the European aviation sector, it would mean that more than , "ghost flights" were operating in Europe this year, spitting out carbon dioxide emissions equivalent to 1.

Some believe the issue has been overhyped and is likely not more prevalent than the few airlines that have admitted to operating them. Others say there are likely tens of thousands of such flights operating — with their carriers declining to say anything because of the PR blowback.

Long-time Slashdot reader olddoc and his wife have three frequently-used credit cards, stored and many online businesses for easy checkout.

Once there was a charge for thousands of dollars at a bar. The card companies seem to pick up the fact that they are fraudulent even though once it was described as "chip present". What can we do to cut down the number of times we have to update all our ongoing bills with a new card number?

The original submission acknowledges that "We have never lost money to fraud, just time. Never ever have your card stored at an online business even if it's more inconvenient to enter it every time. You NEVER know how your number is stored, it can be stored in a database that's not secure enough or it can be stored in an encrypted cookie on your computer in which case that cookie might be read and decrypted by just about any web site out there if they have figured out how to access cookies for another site.

There are a lot of ways that your card details can leak. But is there a better solution? Share your own thoughts in the comments. How can you keep your credit card numbers from being stolen? In ," notes The Drift magazine, noting last year's event was held in Monterey, California.

Neither did any of the other "ideas worth spreading" the organization's tagline presented at the TED conference that year — including Monica Lewinsky's massively viral speech about how to stop online bullying through compassion and empathy, or a Google engineer's talk about how driverless cars would make roads smarter and safer in the near future. In fact, seven years after TED , it feels like we are living in a reality that is the exact opposite of the future envisioned that year At the start of the pandemic, I noticed people sharing Gates's talk.

The general sentiment was one of remorse and lamentation: the tech-prophet had predicted the future for us! If only we had heeded his warning! I wasn't so sure. It seems to me that Gates's prediction and proposed solution are at least part of what landed us here. I don't mean to suggest that Gates's TED talk is somehow directly responsible for the lack of global preparedness for Covid. But it embodies a certain story about "the future" that TED talks have been telling for the past two decades — one that has contributed to our unending present crisis.

The story goes like this: there are problems in the world that make the future a scary prospect. Fortunately, though, there are solutions to each of these problems, and the solutions have been formulated by extremely smart, tech-adjacent people.

For their ideas to become realities, they merely need to be articulated and spread as widely as possible. And the best way to spread ideas is through stories In other words, in the TED episteme, the function of a story isn't to transform via metaphor or indirection, but to actually manifest a new world. Stories about the future create the future. Or as Chris Anderson, TED's longtime curator, puts it, "We live in an era where the best way to make a dent on the world It is a seemingly endless index of stories about the future — the future of science, the future of the environment, the future of work, the future of love and sex, the future of what it means to be human — that never materialized.

By this measure alone, TED, and its attendant ways of thinking, should have been abandoned. But the article also notes that TED's philosophy became "a magnet for narcissistic, recognition-seeking characters and their Theranos-like projects. And since the TEDx franchise lets licensees use the brand platform to stage independent events — which is how at a TEDx event, Randy Powell gave his infamous talk about vortex-based mathematics which he said would "create inexhaustible free energy, end all diseases, produce all food, travel anywhere in the universe, build the ultimate supercomputer and artificial intelligence, and make obsolete all existing technology.

TED is probably best understood as the propaganda arm of an ascendant technocracy. The region around this Winter's Olympic venues "is in an extreme drought ," reports CNN, though "even in normal years, it isn't particularly suitable for snow sports.

Just one of the 21 cities that have hosted the Winter Olympics in the past 50 years will have a climate suitable for winter sports by the end of the century, a recent study found , if fossil fuel emissions remain unchecked.

As the planet warms and the weather becomes increasingly more erratic, natural snow is becoming less reliable for winter sports, which forces venues to lean more on artificial snow. But it comes at a cost: human-made snow is incredibly resource-intensive, requiring massive amounts of energy and water to produce in a climate that's getting warmer and warmer. Elite athletes also say that the sports themselves become trickier and less safe when human-made snow is involved And with 1.

It's enough to fill 3, average-sized backyard swimming pools, or — more to the point — it's a day's worth of drinking water for nearly million people The IOC does not face these challenges alone. Artificial snow is being used as a tool to extend ski seasons in competitions and at resorts across the globe, many of which are threatened by the warming temperatures of the climate crisis.

These challenges will continue to drive the snow sports industry toward artificial snow when Mother Nature doesn't produce it.
