Each day leading up through the 16th (the official day Half-Life 2 was launched), Ars Technica will be publishing a new article looking back at the game and its impact. Here's an excerpt from an article published today by Ars Technica's Kyle Orland: When millions of eager gamers first installed Half-Life 2 20 years ago, many, if not most, of them found they needed to install another piece of software alongside it. Few at the time could imagine that piece of companion software -- with the pithy name Steam -- would eventually become the key distribution point and social networking center for the entire PC gaming ecosystem, making the idea of physical PC games an anachronism in the process.

While Half-Life 2 wasn't the first Valve game released on Steam, it was the first high-profile title to require the platform, even for players installing the game from physical retail discs. That requirement gave Valve access to millions of gamers with new Steam accounts and helped the company bypass traditional retail publishers of the day by directly marketing and selling its games (and, eventually, games from other developers). But 2004-era Steam also faced a vociferous backlash from players who saw the software as a piece of nuisance DRM (digital rights management) that did little to justify its existence at the time. In honor of the anniversary, Orbifold Studios released a new Half-Life 2 RTX trailer. "[T]his is a remastering project that leverages the technologies of NVIDIA's RTX Remix and has the blessing of the original developer, Valve," reports Wccftech. "Orbifold Studios, a team of experienced modders, was founded specifically to bring this project to fruition." It's unclear when exactly this project will be finished.

Nvidia is also giving away a custom Half-Life 2 themed RTX 480 Super Founders Edition.

sciencehabit shares a report from Science Magazine: What if, rather than scouring the internet, ChatGPT could search all of the DNA on Earth? That future just got a bit closer with Evo, an AI model reported today in Science. The program -- trained on billions of lines of genetic sequences -- can design new proteins and even whole genomes. Previous AIs could only interpret and predict relatively short sections of DNA, and they could only work with groups of nucleotides -- the A, C, G, T alphabet of DNA -- not individual nucleotides. To take things to the next level, researchers trained Evo on 300 billion nucleotides of sequence information.

In a first test, Evo bested other AI models on predicting the impact of mutations on protein performance. The team then had Evo design new versions of the CRISPR genome editor; the best designs were as good at cutting DNA as a commercial version. And in what study author Brian Hie, a computational biologist at Stanford University, calls the "most futuristic and crazy" part of the study, the researchers asked Evo to generate DNA sequences that are long enough to serve as genomes for bacteria -- a step toward AI-designed synthetic genomes.

Much of the work on AI occurs in secret at companies. But the researchers have released Evo publicly so that other researchers can use it, and Hie says the team has no plans to commercialize its creation. "For now, I see this as a research project."

Datacenter operators are increasingly turning to small modular reactors (SMRs) like those developed by Oklo to meet growing energy demands. According to The Register, Oklo has secured commitments from two major datacenter providers for 750 MW of power, pending regulatory approvals. It brings the firm's planned nuclear build-out to 2.1 gigawatts. From the report: Oklo's designs are, from what we understand, inspired by the Experimental Breeder Reactor II (EBR-II) and utilize liquid-metal cooling. They are capable of producing between 15MW and 50MW of power, depending on the configuration. That means Oklo's datacenter customers plan to deploy somewhere between 15 and 50 of the reactors to satisfy their thirst for electricity. However, they may be waiting a while.

According to Oklo's website, the nuclear startup hopes to bring its first plant online before the end of the decade. Before that can happen, though, Oklo will need to obtain approval from the Nuclear Regulatory Commission -- something for which it says it's already submitted applications. In 2022, the watchdog rejected an Oklo plan to build a small atomic reactor in Idaho, citing "significant information gaps" on safety-related measures.

That said, Oklo has lately received support from US government agencies including the Department of Energy (DoE), which has awarded a site use permit, while Idaho National Laboratory -- home of EBR-II -- has provided fuel material to support the efforts. Speaking of fuel, Oklo's designs may not suffer from the challenges other SMR startups, like Terrapower, have encountered. Oklo's designs are intended to run on recycled nuclear waste products from traditional reactors. In fact, the startup is currently working with DoE national labs to develop new fuel recycling technologies. Oklo hopes to bring a commercial-scale recycling plan online by the early 2030s.

Francois Chollet, an AI pioneer and creator of the Keras framework, announced that he's leaving Google to co-found a new company. Neowin reports: In his parting message, Chollet assured that he would still be active with Keras and participate in its development on GitHub. His successor, Jeff Carpenter, will now lead Keras at Google, and Chollet expressed his full confidence in the team's future direction.

Keras has come a long way since Chollet released it in 2015, initially as a high-level neural network API meant for simplicity and accessibility. Keras quickly gained traction in the AI community for its user-friendly Python interface and compatibility with frameworks like TensorFlow, simplifying machine learning model building for developers across various levels. Google published a blog post praising Chollet and reaffirming their commitment to Keras.

Last year, Google lost the "Godfather of AI," Geoffrey Hinton, who left the company after nearly a decade. He said he quit his job at Google so he can freely speak out about the risks of AI.

quonset shares a report from CNN: Between August 2022 and January 2024, hundreds of swatting calls were made across the country targeting religious institutions, government offices, schools, and random people. Authorities were finally able to track down the criminal, Alan Fillon, who entered the plea to four counts of making interstate threats to injure the person of another, the US Attorney's Office for the Middle District of Florida said in a news release. He faces up to five years in prison on each count. A sentencing date has not yet been set.

The US Attorney's Office said Filion made more than 375 swatting and threat calls from August 2022 to January 2024. Those calls included ones in which he claimed to have planted bombs in targeted locations or threatened to detonate bombs and/or conduct mass shootings at those locations, prosecutors said. He targeted religious institutions, high schools, colleges and universities, government officials and people across the United States. Filion was 16 at the time he placed the majority of the calls.

Phoronix's Michael Larabel reports: The OpenMP Architecture Review Board announced from SC24 that OpenMP 6.0 is now available as a major upgrade to the OpenMP specification for multi-process programming within C / C++ / Fortran. A big emphasis on OpenMP 6.0 is making it easier for developers to embrace. OpenMP 6.0 aims to make it easier to support parallel programming in new applications, easier to adapt to new use-cases, and more fine-grained developer control.

OpenMP 6.0 simplifies task programming with support for task execution by free-agent threads, allowing for recording of task graphs for efficient replay, and other improvements. OpenMP 6.0 also brings support for array syntax applications, better control over memory allocations and accessibility, easier writing of asynchronous data transfers, and other improvements for enhanced device support / offloading. There is also easier programming of loop transformations, support for induction, support for C23 / Fortran 2023 / C++23, grater user control of storage resources and memory spaces, and other improvements.

An update to OpenAI's ChatGPT app for macOS adds integration with third-party apps, including developer tools such as VS Code, Terminal, iTerm2 and Apple's Xcode. 9to5Mac reports: In a demo seen by 9to5Mac, ChatGPT was able to understand code from an Xcode project and then provide code suggestions without the user having to manually copy and paste content into the ChatGPT app. It can even read content from more than one app at the same time, which is very useful for working with developer tools. According to OpenAI, the idea is to expand integration to more apps in the future. For now, integration with third-party apps is coming exclusively to the Mac version of ChatGPT, but there's another catch. The feature requires a paid ChatGPT subscription, at least for now.

ChatGPT Plus and Team subscribers will receive access to integration with third-party apps on macOS starting today, while access for Enterprise and Education users will be rolled out "in the next few weeks." OpenAI told 9to5Mac that it wants to make the feature available to everyone in the future, although there's no estimate of when this will happen. For privacy reasons, users can control at any time when and which apps ChatGPT can read. The app can be downloaded here.

An anonymous reader quotes a report from Data Center Dynamics: The Japanese government is planning to invest approximately $65 billion to support the country's semiconductor and AI industries. The initiative, which will run until the end of the decade, is expected to generate ~$104 billion in public and private investment during the period. According to a report from Reuters, this new round of funding will specifically target state-backed chip foundry Rapidus and other AI chip suppliers.

Rapidus was founded in November 2022 when the Japanese government and eight Japanese technology and automotive firms, including SoftBank, Sony, and NTT, invested more than $500 million to launch the business. Speaking at a news conference this week, Japanese Prime Minister Shigeru Ishiba did not provide any information about how the venture would be financed but said the government would not issue deficit-covering bonds. Japan's government also said it won't raise taxes to finance the $65 billion plan.

An academic journal has retracted two papers because it determined their authors used unlicensed software. The Register: Elsevier's Ain Shams Engineering Journal withdrew two papers exploring dam failures after complaints from Flow Science, the Santa Fe, New Mexico-based maker of a computational fluid dynamics application called FLOW-3D.

"Following an editorial investigation as a result of a complaint from the software distributor, the authors admitted that the use of professional software, FLOW-3D program for the results published in the article, was made without a license from the developer," a note from the journal's editor-in-chief explains.

"One of the conditions of submission of a paper for publication is that the article does not violate any intellectual property rights of any person or entity and that the use of any software is made under a license or permission from the software owner."

The Federal Trade Commission is preparing to launch an investigation into anti-competitive practices at Microsoft's cloud computing business, Financial Times reported Thursday, as the US regulator continues to pursue Big Tech in the final weeks of Joe Biden's presidency. From the report: The FTC is examining allegations that Microsoft is abusing its market power in productivity software by imposing punitive licensing terms to prevent customers from moving their data from its Azure cloud service to competitors' platforms, according to people with direct knowledge of the matter.

Tactics being examined include substantially increasing subscription fees for those that leave, charging steep exit fees and allegedly making its Office 365 products incompatible with rival clouds, they added.

An anonymous reader shares a report: After dragging its feet for years, Microsoft has finally released the first official Windows 11 ISOs for PCs with an Arm64 processor. This means users can now clean install Windows 11 using official offline media on an Arm64-based PC, including the latest Snapdragon X Copilot+ PCs.

The ISOs contain version 24H2 can be downloaded from the official Microsoft website, and are around 5GB in size depending on the language you select. According to the company, the ISOs are primarily designed for running Windows 11 in a virtual machine on Arm64 PCs. However, it also mentions that you can use them to clean install Windows 11 directly onto Arm64 hardware too.Unfortunately, depending on the Arm64 PC you have, you may need to do some additional work to get the ISO bootable.

Scientists have developed a method to reuse components from decommissioned data center servers, potentially reducing the carbon footprint of cloud computing infrastructure.

The research team from Microsoft, Carnegie Mellon University and the University of Washington demonstrated that older RAM modules and solid-state drives can be safely repurposed in new server builds without compromising performance, according to papers presented at recent computer architecture conferences.

When combined with energy-efficient processors, the prototype servers achieved an 8% reduction in total carbon emissions during Azure cloud service testing. Researchers estimate the approach could cut global carbon emissions by up to 0.2% if widely adopted. The cloud computing industry currently accounts for 3% of global energy consumption and could represent 20% of emissions by 2030, according to computing experts. Most data centers, including Microsoft's Azure, typically replace servers every 3-5 years.

South Korean researchers have developed a "morphing" wheel that can navigate stairs and obstacles up to 1.3 times its radius, potentially revolutionizing mobility devices and robotics.

The wheel, created by the Korea Institute of Machinery and Materials (KIMM), features a chain-based outer hoop and sensor-controlled spoke wires that adjust stiffness based on terrain. Inspired by water droplet mechanics, it transitions between solid and fluid states when encountering impediments.

Google is rolling out AI-powered scam call detection for Android phones, aiming to protect users from increasingly sophisticated phone fraud schemes. The new feature, available in beta for Pixel 6 and newer devices, analyzes conversation patterns in real-time to identify potential scams. When suspicious patterns emerge, such as urgently requesting fund transfers, the system alerts users through audio, haptic, and visual warnings.

The detection system operates entirely on-device using Google's machine learning models, with no call audio or transcripts stored or transmitted externally. While Pixel 9 devices utilize Google's advanced Gemini Nano AI model, earlier Pixel phones use the standard machine learning for detection, the company said. The feature, which is opt-in and can be disabled at any time, is currently limited to English-speaking Phone by Google beta users in the United States. Google plans to expand availability to additional Android devices in the future.

Public trust in scientists is showing signs of recovery, according to a new Pew Research Center survey, though levels remain below pre-pandemic highs. The October 2024 study, which surveyed 9,593 U.S. adults, reveals that 76% of Americans have "a great deal" or "a fair amount" of confidence in scientists' commitment to public interests -- a modest increase from 73% in 2023, but still short of the 87% recorded in early 2020.

The survey -- whose results were released Thursday [PDF] -- also highlights persistent partisan differences, with 88% of Democrats expressing trust in scientists compared to 66% of Republicans. However, Republican trust increased by 5% points since 2023, marking the first uptick since the pandemic's onset. On scientists' policy engagement, Americans remain divided: 51% support scientists' active participation in policy debates concerning scientific matters, while 48% prefer they maintain focus on research and empirical findings.
