Researchers Release ‘PolyCoder’, the First Open-Source Code-Generating AI Model

“Code generation AI — AI systems that can write in different programming languages given a prompt — promise to cut development costs while allowing coders to focus on creative, less repetitive tasks,” writes VentureBeat.

“But while research labs like OpenAI and Alphabet-backed DeepMind have developed powerful code-generating AI, many of the most capable systems aren’t available in open source.”

For example, the training data for OpenAI’s Codex, which powers GitHub’s Copilot feature, hasn’t been made publicly available, preventing researchers from fine-tuning the AI model or studying aspects of it such as interpretability.

To remedy this, researchers at Carnegie Mellon University — Frank Xu, Uri Alon, Graham Neubig, and Vincent Hellendoorn — developed PolyCoder, a model based on OpenAI’s GPT-2 language model that was trained on a database of 249 gigabytes of code across 12 programming languages. While PolyCoder doesn’t match the performance of top code generators in every task, the researchers claim that PolyCoder is able to write in C with greater accuracy than all known models, including Codex….

“Large tech companies aren’t publicly releasing their models, which is really holding back scientific research and democratization of such large language models of code,” the researchers said. “To some extent, we hope that our open-sourcing efforts will convince others to do the same. But the bigger picture is that the community should be able to train these models themselves. Our model pushed the limit of what you can train on a single server — anything bigger requires a cluster of servers, which dramatically increases the cost.”

Is a New Iron Curtain Descending Across Russia’s internet?

Cogent Communications, one of the world’s largest internet intercontinental backbone providers, has cut ties with Russian customers over its invasion of Ukraine. The Verge reports:

In a letter to Russian customers obtained by The Washington Post, Cogent cited “economic sanctions” and “the increasingly uncertain security situation” as the motives behind its total shutdown in the country. Cogent similarly told The Verge that it “terminated its contracts” with Russian customers in compliance with the European Union’s move to ban Russian state-backed media outlets.

As Doug Madory, an internet analyst at network tracking company Kentik points out… unplugging Russia from Cogent’s global network will likely result in slower connectivity, but won’t completely disconnect Russians from the internet… Traffic from Cogent’s former customers will instead fall back on other backbone providers in the country, potentially resulting in network congestion. There isn’t any indication as to whether other internet backbone providers will also suspend services in Russia.
Digital rights activists have criticized Cogent’s decision to disconnect itself from Russia, arguing that it could prevent Russian civilians from accessing credible information about the invasion. “Cutting Russians off from internet access cuts them off from sources of independent news and the ability to organize anti-war protests,” Eva Galperin, the director of cybersecurity at the digital rights group Electronic Frontier Foundation, said on Twitter….

Cogent’s goal is to prevent the Russian government from using the company’s networks for cyberattacks and propaganda, The Post reports.

The Post argues that on a larger scale,”these moves bring Russia closer to the day when its online networks face largely inward, their global connections weakened, if not cut off entirely.”
“I am very afraid of this,” said Mikhail Klimarev, executive director of the Internet Protection Society, which advocates for digital freedoms in Russia. “I would like to convey to people all over the world that if you turn off the Internet in Russia, then this means cutting off 140 million people from at least some truthful information. As long as the Internet exists, people can find out the truth. There will be no Internet — all people in Russia will only listen to propaganda….”

[E]ven two weeks ago, Russia’s Internet was comparatively free and integrated into the larger online world, allowing civil society to organize, opposition figures to deliver their messages and ordinary Russians to gain ready access to alternative sources of news in an era when Putin was strangling his nation’s free newspapers and broadcast stations…. Patrick Boehler, head of digital strategy at Radio Free Europe, said CrowdTangle data showed that independent news stories in the Russian language worldwide were getting shared many more times on social media than stories from state-run media. He said that once the Kremlin lost control of the narrative, it would have been hard to regain.

Now the last independent journalistic outposts are gone, and the Internet options are increasingly constricted through a combination of forces — all spurred by war in Ukraine but coming from both within and outside Russia…. Government censors also blocked access to the BBC, Voice of America, Radio Free Europe/Radio Liberty and Deutsche Welle, as well as major Ukrainian websites. The BBC, CNN and other international news organizations said they were suspending reporting in Russia because of a new law that could result in 15 years of prison for publishing what government officials deem false news on the war.

Meanwhile, Politico reminds us that even Oracle has shut down its Russian cloud service operations.
Laura Manley, the executive director of Harvard University’s Shorenstein Center on Media, Politics and Public Policy, said Russia is creating a perfect situation to control its narrative and limit outside coverage of its Ukrainian invasion by Western social media sources. “You have the lack of eyewitness information because you have critical infrastructure being shut off,” she said. “So it’s sort of a worst case scenario in terms of getting real-time accurate information.”

1 Million Fitbit Ionic Smartwatches Recalled Over Reports of Overheating Batteries and More than 100 Burn Injuries

“Fitbit has announced a voluntary recall of its Ionic Smartwatch,” reports Newsweek, “amid more than 170 reports that the battery has overheated, causing more than 100 reports of burn injuries….”

The Ionic smartwatch was first introduced in 2017 and the company stopped producing it in 2020. When worn, the smartwatch tracks activity, heart rate, and sleep. According to the U.S. Consumer Product Safety Commission (CPSC), one million of the watches were sold in the U.S. while a further 693,000 were sold internationally.

The company has received 115 reports in the U.S. and 59 reports internationally of the watch’s lithium-ion battery overheating, leading to 78 reports of burn injuries in the U.S. and 40 reports of burn injuries internationally, the CPSC added. Some burns were particularly severe, with four reports of second-degree burns and two reports of third-degree burns. Third-degree burns, in which multiple layers of skin are destroyed, are the most harmful of the two….

In a statement published on its website yesterday, the company said it would offer a $299 refund to Fitbit Ionic customers and “the health and safety of Fitbit users is our highest priority.”

“If you own a Fitbit Ionic, please stop using your device,” the company added.

Fitbit said the Ionic can be identified via the model number FB503 on the back of the watch under the “CE” mark, while those with a Fitbit account can check if an Ionic is connected to their account by clicking on the Today tab, then their profile picture, and then the Account page.

Ukraine Receives $42M in Cryptocurrency Donations – Plus 180 NFTs They Didn’t Ask For

Thursday the Washington Post reported the Ukrainian government had already received more than $42 million in cryptocurrency donations since last Saturday — “plus digital artwork including a limited edition worth roughly $200,000,” according to blockchain analytics firm Elliptic.

Some of the crypto donations have already been converted into traditional currency, primarily euros, according to Kuna.io, the Kyiv-based cryptocurrency exchange that helped the government set up and manage its crypto wallets for donations. The money was then used to buy critical supplies like drones, bulletproof vests, heat-sensitive goggles and gasoline, from both state actors and the private sector.

None of the more than 180 donated digital artworks — known as non-fungible tokens, or NFTs — have been sold, according to data from blockchains, which store information in an immutable, public digital ledger…. Ukraine, which hadn’t asked for NFTs, received a map of the Donetsk area of eastern Ukraine, parts of which have been controlled by Russian-backed separatists, in the colors of the Ukrainian flag, plus photos of blue-and-yellow peace signs and an animated “fire dragon.” NFT donations also included images from the Shibelon collection, which is “based on a mythology in which Elon Musk was granted genius powers by an alien, who also created bitcoin,” wrote journalist

In addition to well-established cryptocurrencies, Ukraine received donations denominated in almost 100 obscure digital currencies, according to a Post analysis of data from Etherscan. They included a new one named Save Ukraine, another with a racially abusive name, and several themed after crypto community in-jokes focused on dogs and Musk, the Tesla CEO. The government’s strategy has been to convert less popular cryptocurrencies into traditional money first and hold bitcoin and ether in reserves because they are more stable and liquid, Chobanian said. Donations were still streaming in as new efforts to raise crypto for the Ukrainian government cropped up.

Early Tuesday morning Ukraine time, Ukraine’s 31-year-old deputy prime minister, Mykhailo Fedorov, announced AidForUkraine, a joint effort of his Digital Ministry, developers behind the Solana blockchain and Everstake. So far, AidForUkraine has raised $1.4 million, according to its website…. The speed with which the AidForUkraine fundraising effort came together was “magic,” said Everstake’s Vasylchuk, who fled Kyiv days before the invasion thanks to his pilot’s license and is in temporary housing in Florida…. Beyond the official government-led effort, Come Back Alive, an NGO benefiting Ukraine’s army, has also received millions in cryptocurrency donations — and is getting millions more from UkraineDAO, a group organized on the blockchain that held an auction to raise funds, according to blockchain data. The NGO organizers pivoted to crypto after their campaign was suspended from Patreon. But UkraineDAO is limiting spending to helping the victims of war, the New York Times reported. Patreon spokesperson Ellen Satterwhite said that would “absolutely be allowable under our guidelines.”

Elsewhere On GoFundMe, Mila Kunis and Ashton Kutcher have already raised over $15 million for refugee and humanitarian aid — in just one day.

Protein Tweak Makes CRISPR Gene Editing 4,000 Times Less Error-Prone

Researchers at the University of Texas at Austin have identified a previously unknown structure of the protein that’s responsible for making edits to the wrong sections of DNA. After some tweaking, they were able to reduce the likelihood of off-target mutations by 4,000 times. New Atlas reports: CRISPR tools use certain proteins, most often Cas9, to make precise edits to specific DNA sequences in living cells. This can involve cutting out problematic genes, such as those that cause disease, and/or slotting in beneficial ones. The problem is that sometimes the tool can make changes to the wrong parts, potentially triggering a range of other health issues. And in the new study, the UT researchers discovered how some of these errors can happen. Usually, the Cas9 protein is hunting for a specific sequence of 20 letters in the DNA code, but if it finds one where 18 out of 20 match its target, it might make its edit anyway. To find out why this occurs, the team used cryo-electron microscopy to observe what Cas9 is doing when it interacts with a mismatched sequence.

To their surprise, they discovered a strange finger-like structure that had never been observed before. This finger reached out and stabilized the DNA sequence so the protein could still make its edit. Having uncovered this mechanism, the team tweaked this finger so that it no longer stabilized the DNA, instead pushing away from it. That prevents Cas9 from editing that sequence, making the tool 4,000 times less likely to produce off-target mutations. The team calls the new protein SuperFi-Cas9. The research was published in the journal Nature.

Samsung Says It Will Release An Update To Address App Throttling Issues

In a statement to TechCrunch, a Samsung spokesperson said the company will release a software update to allow users to have more control over throttling. “Samsung has not provided details about when the update will roll out to users,” notes the report. From the report: “Our priority is to deliver the best mobile experience for consumers. We value the feedback we receive about our products and after careful consideration, we plan to roll out a software update soon so users can control the performance while running game apps,” a spokesperson from Samsung said in an email.

Samsung’s promise follows reports that the tech giant’s phones are throttling the performance of around 10,000 apps, as first reported by Android Authority, and via Twitter complaints, plus Samsung’s Korean community forums. The company’s Game Optimizing Service (GOS) software, which optimizes the performance of CPU and GPU to prevent excessive heating when playing a game for a long time, appeared to be at the core of the issue, but the list of affected apps wasn’t limited to games. However, Samsung has disputed claims that Game Optimizing Service was throttling non-gaming apps. “The Game Optimizing Service (GOS) has been designed to help game apps achieve a great performance while managing device temperature effectively. GOS does not manage the performance of non-gaming apps,” the spokesperson said.

California Issues Permits To Cruise, Waymo For Autonomous Vehicle Service

The California Public Utilities Commission (CPUC) on Monday issued permits to self-driving units of General Motors and Alphabet to allow for passenger service in autonomous vehicles with safety drivers present. Reuters reports: CPUC said the GM unit Cruise and Alphabet’s Waymo are under Drivered Deployment permits authorized to collect fares from passengers and may offer shared rides. Prior to the announcement Cruise and Waymo had been permitted to provide passenger service only on a testing basis with no fare collection permitted.

Starting Monday, Cruise is allowed to provide the “Drivered Deployment” service on some public roads in San Francisco between the hours of 10 p.m. and 6 a.m. at speeds of up to 30 miles per hour, while Waymo can offer service in parts of San Francisco and San Mateo counties at speeds of up to 65 miles per hour, CPUC said. Neither company is allowed to operate during heavy fog or heavy rain. […] Waymo said it has tens of thousands of riders on a waitlst in California after it launched a tester program in August. “We’ll begin offering paid trips through the program in the coming weeks,” the company said.

Europe’s Largest Nuclear Power Plant On Fire After Russian Shelling

Russian forces shelled Europe’s largest nuclear plant early Friday in the battle for control of a crucial energy-producing city, and the power station was on fire. The Associated Press reports: Plant spokesman Andriy Tuz told Ukrainian television that shells were falling directly on the Zaporizhzhia plant and had set fire to one of the facility’s six reactors. That reactor is under renovation and not operating, but there is nuclear fuel inside, he said. Firefighters cannot get near the fire because they are being shot at, Tuz said. A government official told The Associated Press that elevated levels of radiation were detected near the site of the plant, which provides about 25% of Ukraine’s power generation. The official spoke on condition of anonymity because the information has not yet been publicly released. Tuz said it is urgent to stop the fighting to put out the flames.

Mayor Dmytro Orlov and the Ukrainian state atomic energy company reported that a Russian military column was heading toward the nuclear plant. Loud shots and rocket fire were heard late Thursday. […] Ukrainian Prime Minister Denys Shmyhal called on the West to close the skies over the country’s nuclear plants as fighting intensified. “It is a question of the security of the whole world!” he said in a statement. The U.S. and NATO allies have ruled out creating a no-fly zone since the move would pit Russian and Western military forces against each other.

Rivian CEO Apologizes, Walks Back Preorder Price Hikes After Customer Backlash

cartechboy writes: Rivian’s CEO, RJ Scaringe, admitted the company messed up. In a lengthy apology, the executive said the company broke people’s trust. Rivian’s walking back the large, in some cases 20%, price increases introduced earlier in the week for any preorder holder prior to March 1. [However, the price increases stay in effect for anyone who ordered after March 1.] “We wrongly decided to make these changes apply to all future deliveries, including pre-existing configured preorders,” Scaringe said, noting that the company “failed to to appreciate” how customers viewed their configurations and pricing.

Scaringe also acknowledged the company “wrongly assumed” the newly announced dual-motor models and standard battery pack would provide satisfactory price points similar to the original configurations.
