Twitch shutting down in South Korea due to network fees
Twitch is shutting down in South Korea due to prohibitively expensive network fees. Despite efforts to reduce costs, such as lowering stream quality and using peer-to-peer networks, Twitch could not make it profitable to operate in the country. South Korea's model of double charging ISPs and content providers for bandwidth fees is a major factor in this issue. ISPs in other markets, inspired by South Korea's approach, are also pushing for content providers to pay for network costs.
Privacy concerns with smart devices
A marketing company named CMG Local Solutions claims to use active listening to target ads by eavesdropping on conversations through smart devices. While the extent of their capabilities is unclear, it raises valid concerns about the use of voice-controlled devices and the potential misuse of collected data. Although it is challenging to determine the full extent of what these devices do with user data, it is reasonable to assume that keywords are being recorded and processed by manufacturers. The push for voice control raises questions about why companies are promoting this feature despite the cost and privacy implications.
Hardening Linux container hosts with mandatory access controls
When it comes to hardening Linux container hosts with MAC frameworks, there are several options available, including AppArmor, SELinux, TrustedBSD, and Landlock. Each framework has its own trade-offs and capabilities. TrustedBSD, integrated into FreeBSD, allows custom security policies to be created for specific use cases. AppArmor, primarily used in Ubuntu, can be adjusted to make profiles more permissive or restrictive depending on the application's needs. While SELinux and Landlock offer similar capabilities, their usage may vary depending on the specific environment and requirements. Overall, understanding the trade-offs and having expertise in these frameworks is crucial for effectively hardening container hosts.
