Discussion on whether hobbyists can experiment with RL+LLMs on normal hardware. Some share simple implementations and GitHub repos showing it's doable, while others note hardware limitations.
6YouTube DRM added on ALL videos with TV (TVHTML5) clients
- Reports indicate that YouTube is testing a new system where some accounts are only receiving DRM-protected video formats on TV platforms. This affects various TV clients including PS3, web browsers, and Apple TV, impacting the ability to access non-DRM formats. The test appears to be part of a controlled experiment affecting select users.
Understanding innertube and DRM

10What made the Irish famine so deadly
- This excerpt explores the Irish Potato Famine through the lens of Oscar Wilde's family: his father William, who meticulously documented famine deaths in census reports; his mother Jane, who wrote passionate nationalist poetry about it; and Oscar himself, who later addressed food scarcity through subtle comedy in "The Importance of Being Earnest."
Death toll and depopulation
Irish famine killed over 10% of population, higher than Bengal famine's 3.5%. Ireland's population still hasn't recovered to pre-famine levels. Mass emigration followed, with many Irish moving to America.British colonial policy
Food continued to be exported from Ireland during famine under British rule. Policy prioritized free trade over saving lives. Relief efforts were deliberately limited to avoid creating "dependency" among Irish.Education and awareness
Discussion of how colonial history is taught differently across countries. Many note British schools historically glossed over empire's dark aspects, while other European nations vary in addressing their colonial pasts.
