Are AI Coding Assistants Really Saving Developers Time?

Par : EditorDavid
29 septembre 2024 à 11:34
Uplevel provides insights from coding and collaboration data, according to a recent report from CIO magazine — and recently they measured "the time to merge code into a repository [and] the number of pull requests merged" for about 800 developers over a three-month period (comparing the statistics to the previous three months). Their study "found no significant improvements for developers" using Microsoft's AI-powered coding assistant tool Copilot, according to the article (shared by Slashdot reader snydeq): Use of GitHub Copilot also introduced 41% more bugs, according to the study... In addition to measuring productivity, the Uplevel study looked at factors in developer burnout, and it found that GitHub Copilot hasn't helped there, either. The amount of working time spent outside of standard hours decreased for both the control group and the test group using the coding tool, but it decreased more when the developers weren't using Copilot. An Uplevel product manager/data analyst acknowledged to the magazine that there may be other ways to measure developer productivity — but they still consider their metrics solid. "We heard that people are ending up being more reviewers for this code than in the past... You just have to keep a close eye on what is being generated; does it do the thing that you're expecting it to do?" The article also quotes the CEO of software development firm Gehtsoft, who says they didn't see major productivity gains from LLM-based coding assistants — but did see them introducing errors into code. With different prompts generating different code sections, "It becomes increasingly more challenging to understand and debug the AI-generated code, and troubleshooting becomes so resource-intensive that it is easier to rewrite the code from scratch than fix it." On the other hand, cloud services provider Innovative Solutions saw significant productivity gains from coding assistants like Claude Dev and GitHub Copilot. And Slashdot reader destined2fail1990 says that while large/complex code bases may not see big gains, "I have seen a notable increase in productivity from using Cursor, the AI powered IDE." Yes, you have to review all the code that it generates, why wouldn't you? But often times it just works. It removes the tedious tasks like querying databases, writing model code, writing forms and processing forms, and a lot more. Some forms can have hundreds of fields and processing those fields along with doing checks for valid input is time consuming, but can be automated effectively using AI. This prompted an interesting discussion on the original story submission. Slashdot reader bleedingobvious responded: Cursor/Claude are great BUT the code produced is almost never great quality. Even given these tools, the junior/intern teams still cannot outpace the senior devs. Great for learning, maybe, but the productivity angle not quite there.... yet. It's damned close, though. GIve it 3-6 months. And Slashdot reader abEeyore posted: I suspect that the results are quite a bit more nuanced than that. I expect that it is, even outside of the mentioned code review, a shift in where and how the time is spent, and not necessarily in how much time is spent. Agree? Disagree? Share your own experiences in the comments. And are developers really saving time with AI coding assistants?

California's Governor Vetoes Bill Requiring Speeding Alerts in New Cars

Par : EditorDavid
29 septembre 2024 à 07:34
California governor Gavin Newsom "vetoed a bill Saturday that would have required new cars to beep at drivers if they exceed the speed limit," reports the Associated Press: In explaining his veto, Newsom said federal law already dictates vehicle safety standards and adding California-specific requirements would create a patchwork of regulations. The National Highway Traffic Safety "is also actively evaluating intelligent speed assistance systems, and imposing state-level mandates at this time risks disrupting these ongoing federal assessments," the Democratic governor said... The legislation would have likely impacted all new car sales in the U.S., since the California market is so large that car manufacturers would likely just make all of their vehicles comply... Starting in July, the European Union will require all new cars to have the technology, although drivers would be able to turn it off. At least 18 manufacturers including Ford, BMW, Mercedes-Benz and Nissan, have already offered some form of speed limiters on some models sold in America, according to the National Transportation Safety Board.

Can AI Developers Be Held Liable for Negligence?

Par : EditorDavid
29 septembre 2024 à 03:34
Bryan Choi, an associate professor of law and computer science focusing on software safety, proposes shifting AI liability onto the builders of the systems: To date, most popular approaches to AI safety and accountability have focused on the technological characteristics and risks of AI systems, while averting attention from the workers behind the curtain responsible for designing, implementing, testing, and maintaining such systems... I have previously argued that a negligence-based approach is needed because it directs legal scrutiny on the actual persons responsible for creating and managing AI systems. A step in that direction is found in California's AI safety bill, which specifies that AI developers shall articulate and implement protocols that embody the "developer's duty to take reasonable care to avoid producing a covered model or covered model derivative that poses an unreasonable risk of causing or materially enabling a critical harm" (emphasis added). Although tech leaders have opposed California's bill, courts don't need to wait for legislation to allow negligence claims against AI developers. But how would negligence work in the AI context, and what downstream effects should AI developers anticipate? The article suggest two possibilities. Classifying AI developers as ordinary employees leaves employers then sharing liability for negligent acts (giving them "strong incentives to obtain liability insurance policies and to defend their employees against legal claims.") But AI developers could also be treated as practicing professionals (like physicians and attorneys). "{In this regime, each AI professional would likely need to obtain their own individual or group malpractice insurance policies." AI is a field that perhaps uniquely seeks to obscure its human elements in order to magnify its technical wizardry. The virtue of the negligence-based approach is that it centers legal scrutiny back on the conduct of the people who build and hype the technology. To be sure, negligence is limited in key ways and should not be viewed as a complete answer to AI governance. But fault should be the default and the starting point from which all conversations about AI accountability and AI safety begin.

US Transportation Safety Board Issues Urgent Alert About Boeing 737 Rudders

Par : EditorDavid
29 septembre 2024 à 02:34
America's National Transportation Safety Board "is issuing 'urgent safety recommendations' for some Boeing 737s..." reports CNN, "warning that critical flight controls could jam." The independent investigative agency is issuing the warning that an actuator attached to the rudder on some 737 NG and 737 MAX airplanes could fail... "Boeing's 737 flight manual instructs pilots confronted with a jammed or restricted rudder to 'overpower the jammed or restricted system (using) maximum force, including a combined effort of both pilots,'" the NTSB said in a news release. "The NTSB expressed concern that this amount of force applied during landing or rollout could result in a large input to the rudder pedals and a sudden, large, and undesired rudder deflection that could unintentionally cause loss of control or departure from a runway," the statement said. "The FAA said United was the only U.S. airline flying planes with the manufacturing defect in the rudder control system," notes the Seattle Times, "and that United has already replaced the component on nine 737s, the only jets in its fleet where it was identified as faulty. However, the NTSB alert may cause the grounding of some 737 MAXs and older model 737NGs flown by foreign air carriers that have not yet replaced the defective part."

Why Boeing is Dismissing a Top Executive

Par : EditorDavid
29 septembre 2024 à 01:34
Last weekend Boeing announced that its CEO of Defense, Space, and Security "had left the company," according to Barrons. "Parting ways like this, for upper management, is the equivalent to firing," they write — though they add that setbacks on Starliner's first crewed test flight is "far too simple an explanation." Starliner might, however, have been the straw that broke the camel's back. [New CEO Kelly] Ortberg took over in early August, so his first material interaction with the Boeing Defense and Space business was the spaceship's failed test flight... Starliner has cost Boeing $1.6 billion and counting. That's lot of money, but not all that much in the context of the Defense business, which generates sales of roughly $25 billion a year.... [T]he overall Defense business has performed poorly of late, burdened by fixed price contracts that have become unprofitable amid years of higher than expected inflation. Profitability in the defense business has been declining since 2020 and started losing money in 2022. From 2022 to 2024 losses should total about $6 billion cumulatively, including Wall Street's estimates for the second half of this year. Still, it felt like something had to give. And the change shows investors something about new CEO Ortberg. "At this critical juncture, our priority is to restore the trust of our customers and meet the high standards they expect of us," read part of an internal email sent to Boeing employees announcing the change. "Why his predecessor — David Calhoun — didn't pull this trigger earlier this year is a mystery," wrote Gordon Haskett analyst Don Bilson in a Monday note. "Can't leave astronauts behind." "Ortberg's logic appears sound," the article concludes. "In recent years, Boeing has disappointed its airline and defense customers, including NASA... "After Starliner, defense profitability, and the strike, Ortberg has to tackle production quality, production rates, and Boeing's ailing balance sheet. Boeing has amassed almost $60 billion in debt since the second tragic 737 MAX crash in March 2019." Thanks to Slashdot reader Press2ToContinue for sharing the news.

Gen Z Grads Are Being Fired Months After Being Hired

Par : EditorDavid
28 septembre 2024 à 22:07
"After complaining that Gen Z grads are difficult to work with for the best part of two years, bosses are no longer all talk, no action — now they're rapidly firing young workers who aren't up to scratch just months after hiring them," writes Fortune. "According to a new report, six in 10 employers say they have already sacked some of the Gen Z workers they hired fresh out of college earlier this year." Intelligent.com, a platform dedicated to helping young professionals navigate the future of work, surveyed nearly 1,000 U.S. leaders... After experiencing a raft of problems with young new hires, one in six bosses say they're hesitant to hire college grads again. Meanwhile, one in seven bosses have admitted that they may avoid hiring them altogether next year. Three-quarters of the companies surveyed said some or all of their recent graduate hires were unsatisfactory in some way... Employers' gripe with young people today is their lack of motivation or initiative — 50% of the leaders surveyed cited that as the reason why things didn't work out with their new hire. Bosses also pointed to Gen Z being unprofessional, unorganized and having poor communication skills as their top reasons for having to sack grads. Leaders say they have struggled with the latest generation's tangible challenges, including being late to work and meetings often, not wearing office-appropriate clothing, and using language appropriate for the workspace. Now, more than half of hiring managers have come to the conclusion that college grads are unprepared for the world of work. Meanwhile, over 20% say they can't handle the workload.

Despite Predictions of Collapse for Ocean Current, Researchers Find a Key Component is 'Remarkably Stable'

Par : EditorDavid
28 septembre 2024 à 21:07
Past studies have suggested a major ocean current could collapse, quickly changing temperatures and climate patterns, reports the Washington Post. "But scientists disagree on whether the the Atlantic Meridional Overturning Circulation (AMOC) is already slowing, and questions remain as to whether a variety of proxy measurements actually indicate a slowdown" — including a new analysis arguing that the current "has remained remarkably stable." One way to detect AMOC weakening is to monitor the strength of its components such as the Florida Current, which flows swiftly from the Gulf of Mexico into the North Atlantic. The current is a "major contributor" to the AMOC, the researchers write, and a slowdown of the current might indicate a slowdown of the AMOC. Scientists have been tracking its strength since the 1980s using a submarine cable that measures the volume of water it transports. In the current study, researchers reconsider the data, correcting for a gradual shift in Earth's magnetic field that they say affected the cable measurements. Previous assessments of the uncorrected data showed a slight slowing in the Florida Current. But when they corrected for the shift in Earth's magnetic field, the researchers write, they found that the current "has remained remarkably stable" and not declined significantly over the past 40 years. The researchers' announcement acknowledges that "It is possible that the AMOC is changing without a corresponding change in the Florida Current..."

Did Canals Help Build Egypt's Pyramids?

Par : EditorDavid
28 septembre 2024 à 20:07
How were the Pyramids built? NBC News reported on "a possible answer" after new evidence was published earlier this year in the journal Communications Earth & Environment. The theory? "[A]n extinct branch of the Nile River once weaved through the landscape in a much wetter climate." Dozens of Egyptian pyramids across a 40-mile-long range rimmed the waterway, the study says, including the best-known complex in Giza. The waterway allowed workers to transport stone and other materials to build the monuments, according to the study. Raised causeways stretched out horizontally, connecting the pyramids to river ports along the Nile's bank. Drought, in combination with seismic activity that tilted the landscape, most likely caused the river to dry up over time and ultimately fill with silt, removing most traces of it. The research team based its conclusions on data from satellites that send radar waves to penetrate the Earth's surface and detect hidden features. It also relied on sediment cores and maps from 1911 to uncover and trace the imprint of the ancient waterway. Such tools are helping environmental scientists map the ancient Nile, which is now covered by desert sand and agricultural fields... The study builds on research from 2022, which used ancient evidence of pollen grains from marsh species to suggest that a waterway once cut through the present-day desert. Granite blocks weighing several tons were transported hundreds of miles, according to a professor of Egyptology at Harvard University — who tells NBC they were moved without wheels. But this new evidence that the Nile was closer to the pyramids lends further support to the evolving "canals" theory. In 2011 archaeologist Pierre Tallet found 30 different man-made caves in remote Egyptian hills, according to Smithsonian magazine. eventually locating the oldest papyrus rolls ever discovered — which were written by the builders of the Great Pyramid of Giza, describing a team of 200 workers moving limestone upriver. And in a 2017 documentary archaeologists were already reporting evidence of a waterway underneath the great Giza plateau. Slashdot reader Smonster found an alternate theory in this 2001 announcement from Caltech: Mory Gharib and his team raised a 6,900-pound, 15-foot obelisk into vertical position in the desert near Palmdale by using nothing more than a kite, a pulley system, and a support frame... One might ask whether there was and is sufficient wind in Egypt for a kite or a drag chute to fly. The answer is that steady winds of up to 30 miles-per-hour are not unusual in the areas where the pyramids and obelisks are found. "We're not Egyptologists," Gharib added. "We're mainly interested in determining whether there is a possibility that the Egyptians were aware of wind power, and whether they used it to make their lives better."

An International Space Station Leak Is Getting Worse, NASA Confirms

Par : EditorDavid
28 septembre 2024 à 18:52
Ars Technica reports NASA officials operating the International Space Station "are seriously concerned about a small Russian part of the station" — because it's leaking. The "PrK" tunnel connecting a larger module to a docking port "has been leaking since September 2019... In February of this year NASA identified an increase in the leak rate from less than 1 pound of atmosphere a day to 2.4 pounds a day, and in April this rate increased to 3.7 pounds a day." A new report, published Thursday by NASA's inspector general, provides details not previously released by the space agency that underline the severity of the problem... Despite years of investigation, neither Russian nor US officials have identified the underlying cause of the leak. "Although the root cause of the leak remains unknown, both agencies have narrowed their focus to internal and external welds," the report, signed by Deputy Inspector General George A. Scott, states. The plan to mitigate the risk is to keep the hatch on the Zvezda module leading to the PrK tunnel closed. Eventually, if the leak worsens further, this hatch might need to be closed permanently, reducing the number of Russian docking ports on the space station from four to three. Publicly, NASA has sought to minimize concerns about the cracking issue because it remains, to date, confined to the PrK tunnel and has not spread to other parts of the station. Nevertheless, Ars reported in June that the cracking issue has reached the highest level of concern on the space agency's 5x5 "risk matrix" to classify the likelihood and consequence of risks to spaceflight activities. The Russian leaks are now classified as a "5" both in terms of high likelihood and high consequence. "According to NASA, Roscosmos is confident they will be able to monitor and close the hatch to the Service Module prior to the leak rate reaching an untenable level. However, NASA and Roscosmos have not reached an agreement on the point at which the leak rate is untenable." The article adds that the Space Station should reach its end of life by either 2028 or 2030, and NASA "intends to transition its activities in low-Earth orbit onto private space stations," and has funded Axiom Space, Blue Origin, and Voyager Space for initial development. "There is general uncertainty as to whether any of the private space station operators will be ready in 2030."

Alcohol Can Increase Your Cancer Risk, Researchers Find

Par : EditorDavid
28 septembre 2024 à 17:38
The world's oldest and largest cancer research association "found excessive levels of alcohol consumption increase the risk for six different types of cancer," reports CBS News: "Some of this is happening through chronic inflammation. We also know that alcohol changes the microbiome, so those are the bacteria that live in your gut, and that can also increase the risk," Dr. Céline Gounder, CBS News medical contributor and editor-at-large for public health at KFF Health News, recently said on "CBS Mornings." But how much is too much when it comes to drinking? We asked experts what to know. "Excessive levels of alcohol" equates to about three or more drinks per day for women and four or more drinks per day for men, Gounder said... Other studies have shown, however, there is no "safe amount" of alcohol, Gounder said, particularly if you have underlying medical conditions. "If you don't drink, don't start drinking. If you do drink, really try to keep it within moderation," she said. Dr. Amy Commander, medical director of the Mass General Cancer Center specializing in breast cancer, told CBS News alcohol is the third leading modifiable risk factor that can increase cancer risk after accounting for cigarette smoking and excess body weight. [Other factors include physical inactivity — and diet]. "There really isn't a safe amount of alcohol for consumption," she said. "In fact, it's best to not drink alcohol at all, but that is obviously hard for many people. So I think it's really important for individuals to just be mindful of their alcohol consumption and certainly drink less." The article also includes an interesting statistic from the association's latest Cancer Progress Report: from 1991 to 2021 there's been a 33% reduction in overall cancer deaths in the U.S. That's 4.1 million lives saved — roughly 136,667 lives saved each year. "So that is hopeful," Commander said, adding that when it comes to preventing cancer, alcohol is just "one piece of the puzzle."

Octopuses Recorded Hunting With Fish - and Punching Those That Don't Cooperate

Par : EditorDavid
28 septembre 2024 à 16:34
Slashdot reader Hmmmmmm shared this report from NBC News: Octopuses don't always hunt alone — but their partners aren't who you'd expect. A new study shows that some members of the species Octopus cyanea maraud around the seafloor in hunting groups with fish, which sometimes include several fish species at once. The research, published in the journal Nature on Monday, even suggests that the famously intelligent animals organized the hunting groups' decisions, including what they should prey upon. What's more, the researchers witnessed the cephalopod species — often called the big blue or day octopus — punching companion fish, apparently to keep them on task and contributing to the collective effort... "If the group is very still and everyone is around the octopus, it starts punching, but if the group is moving along the habitat, this means that they're looking for prey, so the octopus is happy. It doesn't punch anyone..." [said Eduardo Sampaio, a postdoctoral researcher at the Max Planck Institute of Animal Behavior and the lead author of the research]. NBC News says the study is "an indication that at least one octopus species has characteristics and markers of intelligence that scientists once considered common only in vertebrates." Lead author Sampaio agrees that "We are very similar to these animals. In terms of sentience, they are at a very close level or closer than we think toward us."

A Cheap, Low-Tech Solution For Storing Carbon? Researchers Suggest Burying Wood

Par : EditorDavid
28 septembre 2024 à 15:34
Researchers propose a "deceptively simple" way to sequester carbon, reports the Washington Post: burying wood underground: Forests are Earth's lungs, sucking up six times more carbon dioxide (CO2) than the amount people pump into the atmosphere every year by burning coal and other fossil fuels. But much of that carbon quickly makes its way back into the air once insects, fungi and bacteria chew through leaves and other plant material. Even wood, the hardiest part of a tree, will succumb within a few decades to these decomposers. What if that decay could be delayed? Under the right conditions, tons of wood could be buried underground in wood vaults, locking in a portion of human-generated CO2 for potentially thousands of years. While other carbon-capture technologies rely on expensive and energy-intensive machines to extract CO2, the tools for putting wood underground are simple: a tractor and a backhoe. Finding the right conditions to impede decomposition over millennia is the tough part. To test the idea, [Ning Zeng, a University of Maryland climate scientist] worked with colleagues in Quebec to entomb wood under clay soil on a crop field about 30 miles east of Montreal... But when the scientists went digging in 2013, they uncovered something unexpected: A piece of wood already buried about 6½ feet underground. The craggy, waterlogged piece of eastern red cedar appeared remarkably well preserved. "I remember standing there looking at other people, thinking, 'Do we really need to continue this experiment?'" Zeng recalled. "Because here's the evidence...." Radiocarbon dating revealed the log to be 3,775 years old, give or take a few decades. Comparing the old chunk of wood to a freshly cut piece of cedar showed the ancient log lost less than 5 percent of its carbon over the millennia. The log was surrounded by stagnant, oxygen-deprived groundwater and covered by an impermeable layer of clay, preventing fungi and insects from consuming the wood. Lignin, a tough material that gives trees their strength, protected the wood's carbohydrates from subterranean bacteria... The researchers estimate buried wood can sequester up 10 billion tons of CO2 per year, which is more than a quarter of annual global emissions from energy, according to the International Energy Agency.

Open Source Initiative Announces Alliance with Nonprofit Certifications Group

Par : EditorDavid
28 septembre 2024 à 14:34
When it comes to professional certifications, the long-running nonprofit Linux Professional Institute boasts they've issued 250,000, making them the world's largest Linux/Open Source certification body. And last week they announced a "strategic alliance" with the Open Source Initiative (OSI), which will now be "participating in development and maintenance of these programs." The announcement points out that the Open Source Initiative already has many distinct responsibilities. Besides creating the Open Source Definition — and certifying that Open Source licenses meet the requirements of Open Source software — the OSI's mission is to "encourage the growth of Open Source communities around the world," which includes "educational and outreach efforts to spread Open Source principles." So the ultimate goal is "strengthening Linux and Open Source communities," according to the announcement, by "nurturing the growth of more highly skilled professionals," with the OSI encouraging more people to get certifications for employers. The Open Source movement "has never been in greater need of educated professionals," says OSI executive director Stefano Maffulli, "to drive the next leap forward in Open Source understanding, innovation, and adoption... "This partnership with LPI is one in a series of initiatives that will increase accessibility to the certifications and community participation that Open Source needs to thrive." And the LPI's executive director says it's their group's mission "to promote the use of open source by supporting the people who work with it. A closer relationship with OSI makes a valuable contribution to this effort." The move "reaffirms the commitment of LPI and OSI to enhance the adoption of Linux and Open Source technology," according to the announcement.

How California Cuts Greenhouse Gas Emissions - While Its Economy Grows

Par : EditorDavid
23 septembre 2024 à 11:34
In 2022 about 346,000 electric cars were reportedly sold in California. But the same year its greenhouse gas emissions dropped a whopping 9.3 million metric tons — the amount produced by 2.2 million gas-powered cars — lowering emissions 2.4% from the year before. "The biggest drop came from transportation, due largely to the increased use of renewable fuels," according to the state's Air Resources Board, touting a newly-released report. (And electricity sector emissions also fell by 2.6 million metric tons, or 4.1%, "even as electricity usage rose," according to The Hill — "a dichotomy that the regulators attributed to an increase in solar and wind power generation.") So despite a growing economy, "the latest data underscores a continued trend of steady emissions decline..." according to a statement from the Board. "Between 2000 to 2022, emissions fell by 20% while California's gross domestic product increased by 78%, pointing to the effectiveness of the state's climate change and air quality programs." And the amount of carbon dioxide equivalent emitted per unit of economic output ("carbon intensity") has also dropped 55% in the last 20 years: [In 2022] the electricity sector had its lowest carbon intensity since 2000. Wind and solar now represent 30% of generation and in-state solar increased by 15% from 2021, driven by requirements under the state's Cap-and-Trade Program and Renewables Portfolio Standard. Furthermore, California increased its battery storage by 757% from 2019 through 2023, bolstering its renewable energy efforts. The storage capacity is enough to power 6.6 million homes for up to four hours. Industrial emissions declined by 2%, also falling to the lowest level in 22 years. While refinery emissions remained essentially flat, emissions from oil and gas extraction declined, as did emissions from other fuel use, cement manufacturing, and cogeneration facilities. [The Hill says 2022's industrial emissions were 21.7% below year-2000 levels, according to the report.] Livestock emissions, which are responsible for 70% of agriculture's greenhouse gas emissions, peaked in 2012 and once again saw reductions in 2022. The decrease is driven by the use of methane digesters funded by the California Climate Investments and incentivized by the Low Carbon Fuel Standard, which capture emissions at the source and convert them to clean fuel. Landfill methane emissions also continued to decline in 2022. This decline can be attributed in part to the state's efforts to reduce disposal of organic waste, as well as the California Landfill Methane Regulation, which requires landfill operators to monitor and capture emissions escaping from their facilities. One local news site calls the drop in emissions "shocking," but adds that "the trend is expected to continue. In the second quarter of 2024, 118,181 zero-emission vehicles were purchased in the state, good for about one-quarter of all new car sales." California governor Gavin Newsom said his state "is proving that climate action goes hand-in-hand with economic growth. We've slashed carbon pollution by a whopping 20% since the turn of the century all while building the world's fifth largest economy. Cleaner air, more good jobs — that's the California way."

'Forget ChatGPT: Why Researchers Now Run Small AIs On Their Laptops'

Par : EditorDavid
23 septembre 2024 à 07:39
Nature published an introduction to running an LLM locally, starting with the example of a bioinformatician who's using AI to generate readable summaries for his database of immune-system protein structures. "But he doesn't use ChatGPT, or any other web-based LLM." He just runs the AI on his Mac... Two more recent trends have blossomed. First, organizations are making 'open weights' versions of LLMs, in which the weights and biases used to train a model are publicly available, so that users can download and run them locally, if they have the computing power. Second, technology firms are making scaled-down versions that can be run on consumer hardware — and that rival the performance of older, larger models. Researchers might use such tools to save money, protect the confidentiality of patients or corporations, or ensure reproducibility... As computers get faster and models become more efficient, people will increasingly have AIs running on their laptops or mobile devices for all but the most intensive needs. Scientists will finally have AI assistants at their fingertips — but the actual algorithms, not just remote access to them. The article's list of small open-weights models includes Meta's Llama, Google DeepMind's Gemma, Alibaba's Qwen, Apple's DCLM, Mistral's NeMo, and OLMo from the Allen Institute for AI. And then there's Microsoft: Although the California tech firm OpenAI hasn't open-weighted its current GPT models, its partner Microsoft in Redmond, Washington, has been on a spree, releasing the small language models Phi-1, Phi-1.5 and Phi-2 in 2023, then four versions of Phi-3 and three versions of Phi-3.5 this year. The Phi-3 and Phi-3.5 models have between 3.8 billion and 14 billion active parameters, and two models (Phi-3-vision and Phi-3.5-vision) handle images1. By some benchmarks, even the smallest Phi model outperforms OpenAI's GPT-3.5 Turbo from 2023, rumoured to have 20 billion parameters... Microsoft used LLMs to write millions of short stories and textbooks in which one thing builds on another. The result of training on this text, says Sébastien Bubeck, Microsoft's vice-president for generative AI, is a model that fits on a mobile phone but has the power of the initial 2022 version of ChatGPT. "If you are able to craft a data set that is very rich in those reasoning tokens, then the signal will be much richer," he says... Sharon Machlis, a former editor at the website InfoWorld, who lives in Framingham, Massachusetts, wrote a guide to using LLMs locally, covering a dozen options. The bioinformatician shares another benefit: you don't have to worry about the company updating their models (leading to different outputs). "In most of science, you want things that are reproducible. And it's always a worry if you're not in control of the reproducibility of what you're generating." And finally, the article reminds readers that "Researchers can build on these tools to create custom applications..." Whichever approach you choose, local LLMs should soon be good enough for most applications, says Stephen Hood, who heads open-source AI at the tech firm Mozilla in San Francisco. "The rate of progress on those over the past year has been astounding," he says. As for what those applications might be, that's for users to decide. "Don't be afraid to get your hands dirty," Zakka says. "You might be pleasantly surprised by the results."

First released on July 11th, the Firefox-based Zen browser is "taking a different approach to the user interface," according to the blog It's FOSS. The Register says the project "reminds us strongly of Arc, a radical Chromium-based web browser... to modernize the standard web browser UI by revising some fundamental assumptions." [Arc] removes the URL bar from front and center, gets rid of the simple flat list of tabs, and so on. Zen is trying to do some similar things, but in a slightly more moderate way — and it's doing it on the basis of Mozilla's Firefox codebase... Instead of the tired old horizontal tab bar you'll see in both Firefox and Chrome, Zen implements its own tab bar... By default, this tab bar is narrow and just shows page icons — but there are some extra controls at the bottom of the sidebar, one of which expands the sidebar to show page titles too. For us, it worked better than Vivaldi's fancier sidebar. The article concludes it's "a new effort to modernize web browsing by bringing tiling, workspaces, and so on — and it's blissfully free of Google code." One Reddit comment swooned over Zen's "extraordinary" implementation of a distraction-free "Compact Mode" (hiding things like the sidebar and top bar). And It's Foss described it as a "tranquil," browser, "written using CSS, C++, JavaScript, and a few other programming languages, with a community of over 30 people contributing to it." The layout of the interface felt quite clean to me; there were handy buttons on the top to control the webpage, manage extensions, and a menu with additional options... The split-view functionality allows you to open up two different tabs on the same screen, allowing for easy multitasking when working across different webpages... I split two tabs, but in my testing, I could split over 10+ tabs... If you have a larger monitor, then you are in for a treat... The Zen Sidebar feature... can run web apps alongside any open tabs. This can be helpful in situations where you need to quickly access a service like a note-taking app, Wikipedia, Telegram, and others. On the customization side of things, you will find that Zen Browser supports everything that Firefox does, be it the settings, adding new extensions/themes/plugins, etc. The Register points out it's easy to give it a try. "Being based on Firefox means that as well as running existing extensions, it can connect to Mozilla's Sync service and pick up not just your bookmarks, but also your tabs from other instances." And beyond all that, "There's just something satisfying about switching browsers every now and again..." argues the tech site Pocket-Lint: Zen Browser's vertical tabs layout is superb and feels much better than anything available in standard Firefox. [Firefox recently offered vertical tabs and a new sidebar experience in Nightly/Firefox Labs 131.] The tab bar can be set to automatically hide and show up whenever you hover near it, and it also contains quick access buttons to bookmarks, settings, and browsing history. The tab bar also contains a profile switcher... One of the greatest parts of the Zen Browser is the community that has popped up around it. At its heart, Zen Browser is a community-driven project... Zen Browser themes are aesthetic and functional tweaks to the UI. While there aren't a ton available right now, the ones that are show a lot of promise for the browser's future... I've personally gotten great use out of the Super URL Bar theme, which makes your URL bar expand and become the focus of your screen while typing in it... There's a lot you can do to make Zen Browser feel nearly exactly like what you want it to feel like. The "Business Standard calls it "an open-source alternative to Chromium-based browsers," adding "Where Zen truly shines is it offers a range of customisation, tab management, and workspace management..." Their theme store offers a range of options, including modifications to the bookmark toolbar, a floating URL bar, private mode theming, and removal of browser padding. In addition to these, users can also choose from custom colour schemes and built-in theming options... The Sidebar is another neat feature which allows you to open tabs in a smaller, smartphone-sized window. You can view websites in mobile layout by using this panel. It's "focused on being always at the latest version of Firefox," according to its official site, noting that Firefox is known for its security features. But then, "We also have additional security features like https only built into Zen Browser to help keep you safe online." And it also promises automated Releases "to ensure security." It's FOSS adds that you can get Zen Browser for Linux, Windows, and macOS from its official website (adding "They also offer it on the Flathub store for further accessibility on Linux.") And its source code is available on GitHub.

Germany Seizes 47 Crypto Exchanges Used By Ransomware Gangs

German law enforcement seized 47 cryptocurrency exchange services "that facilitated illegal money laundering activities for cybercriminals," according to BleepingComputer, "including ransomware gangs." Long-time Slashdot reader Arrogant-Bastard shares their report: The platforms allowed users to exchange cryptocurrencies without following applicable "Know Your Customer" regulations, meaning that users remained completely anonymous when making transactions. This created a low-risk environment for cybercriminals to launder their proceeds without fearing prosecution or being tracked. "Exchange services that enable such anonymous financial transactions and thus money laundering represent one of the most relevant building blocks in the criminal value chain of the cybercrime phenomenon," reads a Federal Criminal Police Office (BKA) announcement... When visiting any of the seized exchanges, you are now redirected to a warning page titled "Operation Final Exchange," which warns visitors that they have been deceived by the promises of anonymity by the operators of these platforms. The new site notes years-long promises from the exchanges "that their hosting cannot be found, that they do not store any customer data and that all data is deleted immediately after the transaction... "We have found their servers and seized them — development servers, production servers, backup servers. We have their data — and therefore we have your data. Transactions, registration data, IP addresses. "Our search for traces begins. See you soon."

How Cyprus Became a World Leader In Solar Heating

Par : EditorDavid

The republic of Cyprus "has outstripped all other EU member states in embracing hot-water solar systems," reports the Guardian, "with an estimated 93.5 % of households exploiting the alternative energy form for domestic needs." EU figures show the eastern Mediterranean island exceeding renewable energy targets set in the heating and cooling of buildings thanks to the widespread use of the solar thermal technology... [First introduced in the late 1960s], the solar thermal systems not only collected solar energy as heat — usually generated through electricity and the burning of fossil fuels — they were extremely cost-effective and had helped spawn an entire industry [says Charalampos Theopemptou, the island's first environment commissioner and the head of the Cypriot parliament's environment committee]. "It's been great for low-income families and then there's the jobs: so many have been generated," the MP says. "There are the local manufacturers who produce the parts and then all the people who are trained to install them. It's big business." In his role as environment commissioner, Theopemptou pushed hard to make the solar systems obligatory on all newly constructed residential and commercial buildings... The popularity of the water heaters is such that a union of local solar thermal industrialists was established in 1977. Since then, more than 962,564 square cubic metres of "solar [panel] collectors" have been installed, the union says. Increasingly, the country's vibrant tourist industry has also resorted to the green solution with solar-powered hot water systems deployed in, they say, close to 100% of hotels... For Demetra Asprou, a retired engineer, it's obvious that a region blessed with more than 300 days of sunshine a year should embrace solar energy. "It reduces electricity costs, increases the efficiency with which hot water is provided and is kind to the environment," she says. "Why would anyone use other, more traditional means to heat up water when only a few hours of sunlight, between 11am and 2pm, is enough for a 200-litre [44-gallon] tank to be filled with warm water that will last 48 hours? On days when there is no sunlight, which is rare, you always have electricity as a backup if necessary... Installation costs may be three times higher today, but there are EU-funded grants that the government hands out and within a year it's all paid off," she says. "After that, you basically have free hot water and see your electricity bills greatly reduced. In a country like Cyprus, it's a no-brainer."

Windows PowerShell Phish Uses Fake CAPTCHA, Downloads Credential Stealer

Par : EditorDavid

"Many GitHub users this week received a novel phishing email warning of critical security holes in their code," reports Krebs on Security — citing an email shared by one of his readers: "Hey there! We have detected a security vulnerability in your repository. Please contact us at https://github-scanner[.]com to get more information on how to fix this issue...." Clicking the "I'm not a robot" button generates a pop-up message asking the user to take three sequential steps to prove their humanity. Step 1 involves simultaneously pressing the keyboard key with the Windows icon and the letter "R," which opens a Windows "Run" prompt that will execute any specified program that is already installed on the system. Step 2 asks the user to press the "CTRL" key and the letter "V" at the same time, which pastes malicious code from the site's virtual clipboard. Step 3 — pressing the "Enter" key — causes Windows to launch a PowerShell command, and then fetch and execute a malicious file from github-scanner[.]com called "l6e.exe...." According to an analysis at the malware scanning service Virustotal.com, the malicious file downloaded by the pasted text is called Lumma Stealer, and it's designed to snarf any credentials stored on the victim's PC. Even though this might fool some users, Krebs points out that Microsoft "strongly advises against nixing PowerShell because some core system processes and tasks may not function properly without it. What's more, doing so requires tinkering with sensitive settings in the Windows registry..." Thanks to long-time Slashdot reader sinij for sharing the article.
