Legacy Airlines Crack Down on Carry-On Bags

Flying with legacy carriers like British Airways or Air France used to mean included checked baggage and carry-on. However, to compete with low-cost airlines, many legacy carriers are now eliminating free carry-on allowances and even complimentary meals. Air Canada, for example, will no longer allow standard carry-on bags on North American and Caribbean routes from January 3rd, only permitting small personal items. Other airlines like United and Finnair have adopted similar strategies. This 'basic economy' fare is blurring the lines between legacy and budget airlines, adding extra costs for passengers.

2024's Biggest AI Fails: From 'AI Slop' to Out-of-Control Chatbots

2024 saw significant advancements in AI, but also exposed numerous shortcomings. The proliferation of generative AI led to a flood of low-quality content ('AI slop') across the internet, impacting model training effectiveness. AI-generated fake images distorted perceptions of real-world events, such as false event promotions. Elon Musk's xAI company's Grok image generator, lacking necessary safety restrictions, generated violent and illegal content, raising concerns. Out-of-control chatbots and inaccurate information output also caused negative impacts, such as an airline chatbot providing incorrect refund policies. Erroneous AI search result summaries and the spread of deepfake pornography further highlighted the inadequacy of AI ethics and safety regulations.

The Right to Root: Why You Should Own Your Devices

2025-01-13

This article argues for a "right to root" – the consumer's right to install and modify software on any computing device they own outright, regardless of form factor. The author contends that manufacturers' restrictions, justified by security concerns, are anti-consumer, stifle competition, and lead to shorter device lifespans and limited repair options. Using Apple devices as a prime example (comparing the open nature of MacBooks to the closed nature of iPads), the article discusses potential legal solutions and emphasizes that manufacturers should bear the burden of proving the necessity of hardware locks, except in cases like critical medical devices.
