Thailand has become one of the first countries in Asia to access the Sora app, an innovative AI video tool from OpenAI. This launch is significant as it empowers local creators to enhance their storytelling capabilities, tapping into Thailand's vibrant creative scene. The rollout also extends to Vietnam and Taiwan, indicating a broader push for visual storytelling across the region.

Samsung has made a remarkable recovery in its semiconductor division during the third quarter of 2025, reporting an operating profit of KRW 12.2 trillion (approximately US$8.6 billion). This significant turnaround, which more than doubled the profit from the previous quarter, marks the end of four consecutive quarters of decline. The resurgence is largely attributed to the rising demand for AI technologies, showcasing how the tech giant's Device Solutions division is adapting to market needs. This recovery is crucial not only for Samsung but also for the global semiconductor industry, as it reflects a broader trend of increasing reliance on advanced technologies.

Kubernetes promotes itself as 'secure by default,' but this claim can be misleading. The reality is that the default settings in many clusters are overly permissive, which poses significant security risks. A missing security context can lead to vulnerabilities, making it crucial for users to understand the importance of configuring security settings properly. This issue matters because it highlights the need for vigilance in cloud-native environments, where a single oversight can lead to serious breaches.

President Trump recently revealed that he and Chinese President Xi Jinping discussed the access of Nvidia and other chipmakers to the Chinese market. However, they did not talk about the approval of sales for Blackwell chips. This conversation is significant as it highlights ongoing tensions and negotiations between the U.S. and China regarding technology and trade, particularly in the semiconductor industry, which is crucial for both economies.
