Chinese Exports of Green Technologies Surged to Record Levels After Iran War Began

"The war in Iran has sent oil-starved countries scrambling for fuel," CNN reported this week. And many of those countries now want renewable fuels, the article points out, "leaving them turning to the renewables king of the planet: China." Chinese exports of solar technology, batteries and electric vehicles all reached record highs in March, according to energy think tank Ember, a sign that the historic oil supply shock is accelerating the adoption of clean energy around the world... A Thursday report from Ember said China exported 68 gigawatts of solar technology in March, surpassing the previous record set in August by 50%. Fifty countries set new records for Chinese solar imports, with the most significant growth coming from emerging markets in Asia and Africa hit hardest by the energy crisis, according to the think tank. "Fossil shocks are boosting the solar surge," said Euan Graham, senior analyst at Ember, in the report. "Solar has already become the engine of the global economy, and now the current fossil fuel price shocks are taking it up a gear." Ember said exports of solar, batteries and EVs in total rose 70% in March year over year, according to Chinese customs data... China's battery exports reached $10 billion in March, with particularly high growth rates in the European Union, Australia and India, Ember said. Uncertainty over when the Strait of Hormuz will reopen has spurred deeper regional anxieties about energy securi"ty, helping to hasten the transition to clean energy, analysts said. The article notes how different countries are reacting to fuel Asian nations that depend on the Middle East for energy imports "are trying to mitigate fuel shortages by encouraging energy conservation and shortening work hours." The UK's Energy Secretary said this week that the country needed to reduce its reliance on gas for electricity. "As we face the second fossil fuel shock in less than 5 years, the lesson for our country is clear: The era of fossil fuel security is over, and the era of clean energy security must come of age." Pakistan "has been spared some of the impact from the war, since it began drastically importing cheap Chinese solar panels a few years ago. Using solar energy rather than costly oil imports is estimated to save the country billions of dollars each year." "According to the China Passenger Car Association, Chinese exports of electric vehicles and hybrids hit a record high in March, increasing 140% compared with the same period a year ago."

Former NASA Engineers Create Ingenious Way To Save Homes From Wildfires Using Noise

"Scientists have created a miraculous new way to stop fires from spreading through neighborhoods using nothing but sound," reports the New York Post: Former NASA engineers with California-based Sonic Fire Tech found that using sound waves can snuff out blazes and potentially be used to stop another Pacific Palisades inferno... The technology works by targeting oxygen molecules using low-frequency sound waves that vibrate them, stopping the fire from growing. "Sound waves vibrate the oxygen faster than the fuel can use it, and break the chemical reaction of the flame," Remington Hotchkis, Chief Commercialization Officer at Sonic Fire Tech told The Post. The San Bernardino County Fire Department recently tested out the equipment using a backpack version and the results were incredible. Video shows firefighters fighting small blazes on a shrub and a stove top fire with the technology putting it out... In the home application, the system would be alerted/activated if there was a fire, sending the sound waves through a home duct system, essentially snuffing out the blaze. The sound waves can reach as far as 30ft from a home, the report noted. The sound is also harmless to pets and humans. The article includes this quote that an executive at the company gave local news station KMPH. "Our former NASA engineers are rocket scientists, and they say it seems like magic, but it's just physics."

Ask Slashdot: Are YouTube's Subtitles 'Appallingly Bad'?

Long-time Slashdot reader Anne Thwacks frequently uses YouTube's subtitles "not to disturb others in the room, or because my hearing is not very good." But they say there's a new problem. "The subtitling is terrible!" Almost every sentence has a huge error. Proper names are more often wrong than right. Non-English place names are almost always mangled to barely recognizable. And no effort whatsoever is made to use context to figure out whether a place name is Russian or Arabic, and often complete garbage is used in place of a common French, Spanish or Italian name! If AI actually works (I have my doubts about this), surely it would be possible to figure out language contexts. If it is about an event in Italy, then expect a lot of Italian names! If it is about the Russia-Ukraine war, then expect places in Russia or Ukraine to be more plausible than mindless gobbledygook! Does YouTube not know that there are places in the world that are not in America? (However, plenty of names of people and places famous in America are also regularly screwed up.) They argue the subtitles are "appallingly bad" - and that "the situation seems to be getting worse," wondering why the problem isn't addressed with some basic spell-checking. ("I'm sure that the vast majority of foul-ups could be fixed by the use of a dictionary.") Have any Slashdot readers seen similar problems? A friend of mine noticed that YouTube's subtitles even bungled this innocuous song from the 1966. ANNETTE FUNICELLO: "If your love is true love, you can tell by his touch." YOUTUBE SUBTITLE: "If your love is too lava, you can tell by his touch..." Share your own experiences and thoughts in the comments. And do you think YouTube's subtitles are "appallingly bad"?

Email is crazy

Email is like those creaking old Terminators from the '70s which continue to function without complaining. Designed for a world that doesn't exist anymore, it has optional encryption, no built-in auth, three⁺ retrofitted security layers bolted on top, an unstandardized filtering layer and many more quirks. Yet billions of emails arrive correctly every single day. Email is not elegant but nonetheless it is Lindy. In the new age of agentic AI, we can only expect it to metamorphose into another dimension. ↫ Saurabh "Sam" Khawase The fact that email is as complicated as it is bad enough, but having it be so dominantly controlled by only a few large gatekeepers like Google and Microsoft surely isn't helping either. I feel like email is no longer really a technology individuals can actively partake in at every level; it feels much more like WhatsApp or iMessage or whatever in that we just get to send messages, and that's it. Running your own mail sever isn't only a complex endeavour, it's also a continuous cat-and-mouse game with companies like Google and Microsoft to ensure you don't end up on some shitlist and your emails stop arriving. I settled on Fastmail as my email service, and it works quite well. Still, I would love to be able to just run my own email server, or have some of my far more capable friends run one for a small group of us, but it's such a daunting and unpleasant effort few people seem to have the stomach and perseverance for it.

The day I logged 1 in every 2000 public IPv4: visualizing the AI scraper DDoS

What if you run a few online services for you and your friends, like a small git instance and a grocery list service, but you get absolutely hammered by "AI" scrapers? I cannot impress upon you, reader, that this is not only an attack that is coordinated, it is an attack that is distributed. I run a small set of services, basically only for me and my friends. I am not a hyperscaler, I am not a tech company, I am not even a small platform. I have a git forge where I put the shit I make, and a couple other services where me and my friends backup our files or write our grocery lists. I am not fucking Meta and I cannot scale the fuck up just because OpenAI or Anthropic or Meta or whoever is training a model that weeks wants to suck all the content out of my VPS ONCE MORE until it's dry. ↫ lux at VulpineCitrus So how much traffic did the author of this piece, lux, get from "AI" scraping bots? Within a time period of 24 hours, they were hammered by 2040670 unique IP addresses, 98% of which were IPv4 addresses, which means that 1 out of every 2000 publicly available IPv4 addresses were involved in the scraping. Together, they performed over 5 million requests. And just to reiterate: they were scraping a few very small, friends-only services run by some random person. This is absolutely insane. If, at this point in time, with everything that we know about just how deeply unethical every single aspect of "AI" is, you're still using and promoting it, what is wrong with you? If you're so addicted to your "AI" girlfriend's unending stream of useless, forgettable sycophantic slop, despite being aware of the damage you're doing to those around you, there's something seriously wrong with you, and you desperately need professional help. You don't need any of this. The world doesn't need any of this. Nobody likes the slop "AI" regurgitates, and nobody likes you for enabling it. Get help.

Earliest 86-DOS and PC-DOS code released as open source

Microsoft is continuing its efforts to release early versions of DOS as open source, and today we've got a special one. We're stoked today to showcase some newly available source code materials that provide an even earlier look into the development of PC-DOS 1.00, the first release of DOS for the IBM PC. A dedicated team of historians and preservationists led by Yufeng Gao and Rich Cini has worked to locate, scan, and transcribe the stack of DOS-era source listings from Tim Paterson, the author of DOS. The listings include sources to the 86-DOS 1.00 kernel, several development snapshots of the PC-DOS 1.00 kernel, and some well-known utilities such as CHKDSK. Not only were these assembler listings, but there were also listings of the assembler itself! This work offers rare insight into how MS-DOS/PC-DOS came to be, and how operating system development was done at the time, not as it was later reconstructed. ↫ Stacey Haffner and Scott Hanselman It's wild that the source code had to be transcribed from paper, including notes and changes. You can find more information about the process on Gao's website and Cini's website.
