Rulers once closed cafés, burned beans, and even executed someone--all for a cup of coffee. A photograph taken in the 1920s shows a group of men gather at a small roadside coffee stall in Cairo, Egypt. Breakthroughs, discoveries, and DIY tips sent six days a week.

Retired Air Force Gen. Charles Wald joins'Fox News Live' to weigh in on Russia's increased attacks on Ukraine despite President Donald Trump's ultimatum to Vladimir Putin. Russia and Ukraine took aim at corresponding Black Sea resort cities early Thursday morning, just hours after ceasefire talks in Turkey once again failed to deliver results. The major Russian resort city of Sochi was rocked by a Ukrainian drone strike that began around 1 a.m. and lasted until 3 a.m., where one person was reportedly killed and another injured, according to Ukrainian media outlet the Kyiv Independent, though the Ukrainian military has not commented on the incident. An oil depot in the Krasnodar Krai region where Sochi is located was also struck, though the extent of the damage remains unclear.

E-commerce platforms are increasingly reliant on recommendation systems to enhance user experience, retain customers, and, in most cases, drive sales. The integration of machine learning methods into these systems has significantly improved their efficiency, personalization, and scalability. This paper aims to highlight the current trends in e-commerce recommendation systems, identify challenges, and evaluate the effectiveness of various machine learning methods used, including collaborative filtering, content-based filtering, and hybrid models. A systematic literature review (SLR) was conducted, analyzing 38 publications from 2013 to 2025. The methods used were evaluated and compared to determine their performance and effectiveness in addressing e-commerce challenges.

Russian forces have shot down 10 Ukrainian drones heading towards Moscow, according to the city's mayor, Sergei Sobyanin, as Ukraine reported at least one person killed in Russian attacks on the war-torn country. There were no reports of any damage in Moscow on Sunday, but a Ukrainian drone attack led to a short-lived fire at the Azot chemical plant in the neighbouring Tula region, injuring two people, and seven drones were destroyed above the Kaluga region, regional governors said. Rosaviatsia, Russia's civil aviation authority, said on Telegram that, to ensure air safety, it halted flights at Moscow's Vnukovo and Domodedovo, as well as nearby Kaluga (Grabtsevo) airports. The drone attack comes as Kyiv launched an unprecedented drone operation last weekend deep inside Russia, targeting nuclear-capable military aircraft at Russian airbases. Moscow promised to retaliate, unleashing a barrage of attacks in recent days.

Former U.S. ambassador to Ukraine John Herbst explains the impact of the drone strike on Russian air bases. Russian and Ukrainian delegations have begun talks in Istanbul, Turkey, on Monday, less than 24 hours after a massive Ukrainian drone attack struck Russian airfields. The two delegations entered Ciragan Palace in Istanbul alongside a group of senior Turkish officials. It is the second round of peace talks to take place in the three years since Russia invaded Ukraine. Images from the event show many of the Ukrainian delegation wearing military uniforms, while the Russian group exclusively wore suits.

Russian drone and missile attacks on Ukraine have killed at least two people, according to officials, as Ukraine ordered the evacuation of 11 more villages in its Sumy region bordering Russia. Russian troops launched an estimated 109 drones and five missiles across Ukraine on Friday and overnight, the Ukrainian air force said on Saturday, adding that three of the missiles and 42 drones were destroyed and another 30 drones failed to reach their targets without causing damage. The attacks came amid uncertainty over whether Kyiv will take part in a new round of peace talks early next week in Istanbul. In the Russian attacks on Saturday, a child was killed in a strike on the front-line village of Dolynka in the Zaporizhia region, and another was injured, Zaporizhia's Governor Ivan Fedorov said. The shockwave from the blast also damaged several other houses, cars, and outbuildings," Fedorov wrote on Telegram.

British Prime Minister Keir Starmer has discussed the war in Ukraine with leaders of the United States, Italy, France and Germany, a 10 Downing Street spokesperson has said, in advance of US President Donald Trump's planned call with his Russian counterpart, Vladimir Putin, on Monday. The flurry of diplomacy comes shortly after inconclusive direct Russia-Ukraine talks in Istanbul, Turkiye on Friday. The leaders discussed the need for an unconditional ceasefire and for Putin to take peace talks seriously, the spokesperson said late on Sunday, adding that they also raised the use of sanctions if Russia failed to engage seriously in a ceasefire and concerted peace talks. In remarks to reporters earlier on Sunday, German Chancellor Friedrich Merz said he discussed the issue with US Secretary of State Marco Rubio while the two men were attending the inaugural mass of Pope Leo XIV at the Vatican. Merz said he also spoke at length at the Vatican with Ukraine's President Volodymyr Zelenskyy.

Generative AI (GenAI) applications are transforming software engineering by enabling automated code co-creation. However, empirical evidence on GenAI's productivity effects in industrial settings remains limited. This paper investigates the adoption of GenAI coding assistants (e.g., Codeium, Amazon Q) within telecommunications and FinTech domains. Through surveys and interviews with industrial domain-experts, we identify primary productivity-influencing factors, including task complexity, coding skills, domain knowledge, and GenAI integration. Our findings indicate that GenAI tools enhance productivity in routine coding tasks (e.g., refactoring and Javadoc generation) but face challenges in complex, domain-specific activities due to limited context-awareness of codebases and insufficient support for customized design rules. We highlight new paradigms for coding transfer, emphasizing iterative prompt refinement, immersive development environment, and automated code evaluation as essential for effective GenAI usage.

The lack of interpretability is a major barrier that limits the practical usage of AI models. Several eXplainable AI (XAI) techniques (e.g., SHAP, LIME) have been employed to interpret these models' performance. However, users often face challenges when leveraging these techniques in real-world scenarios and thus submit questions in technical Q&A forums like Stack Overflow (SO) to resolve these challenges. We conducted an exploratory study to expose these challenges, their severity, and features that can make XAI techniques more accessible and easier to use. Our contributions to this study are fourfold. First, we manually analyzed 663 SO questions that discussed challenges related to XAI techniques. Our careful investigation produced a catalog of seven challenges (e.g., disagreement issues). We then analyzed their prevalence and found that model integration and disagreement issues emerged as the most prevalent challenges. Second, we attempt to estimate the severity of each XAI challenge by determining the correlation between challenge types and answer metadata (e.g., the presence of accepted answers). Our analysis suggests that model integration issues is the most severe challenge. Third, we attempt to perceive the severity of these challenges based on practitioners' ability to use XAI techniques effectively in their work. Practitioners' responses suggest that disagreement issues most severely affect the use of XAI techniques. Fourth, we seek agreement from practitioners on improvements or features that could make XAI techniques more accessible and user-friendly. The majority of them suggest consistency in explanations and simplified integration. Our study findings might (a) help to enhance the accessibility and usability of XAI and (b) act as the initial benchmark that can inspire future research.
