Deep dives
Vulnerabilities in Windows and Apple's App Store Policies
Windows is currently facing two significant vulnerabilities that could enable hackers to downgrade the operating system, effectively reversing crucial security patches and replacing system files with older, vulnerable versions. This alarming discovery was made by researcher Alan Leviev and presented at major security conferences, prompting a response from Microsoft, although a fix has yet to be issued. Meanwhile, Apple has updated its App Store policies in an attempt to comply with new EU regulations. These changes allow developers to promote offers outside the App Store but also introduce a hefty fee structure, leading to criticism from industry leaders like Epic Games and Spotify, suggesting that Apple's measures may be more about maintaining profit than genuine compliance.
Intel's CPU Instability and OpenAI's GPT-40 Developments
Intel has announced a detailed patch aimed at addressing instability issues in its 13th and 14th generation CPUs, focusing on the K, KF, and KS models, with motherboard manufacturers like Asus and MSI already rolling out BIOS updates. Intel has committed to covering costs for replacements of impacted processors, despite having not yet resolved other ongoing instability issues in some laptop chips. In a separate development, OpenAI has released a system card for its upcoming GPT-40 model, shedding light on delays attributed to the model's emotional outbursts and efforts to compete with other advanced language models. The decision to delay the voice mode rollout indicates OpenAI's focus on refining the technology, amid reports of executive turnover at the company.
