The incident has sparked discussions about the need for better security practices and oversight in government systems, emphasizing the importance of rigorous security audits and shared authentication services.
UK rail minister Peter Hendy influenced the dismissal of engineer Gareth Dennis for raising safety concerns about overcrowding at London’s Euston station.
Hendy threatened to withhold public contracts from Dennis's employer, SYSTRA, and urged disciplinary action, leading to Dennis's dismissal after he refused a financial settlement with a confidentiality clause.
Dennis's warnings to the media about safety risks were in line with concerns from the official rail regulator, despite Network Rail addressing these concerns.
UK rail minister allegedly got an engineer, Gareth Dennis, fired for raising safety concerns, despite his criticisms being relatively mild.
The UK rail network is known for extensive safety measures, including numerous signs and announcements, which some find excessive and patronizing.
The incident highlights ongoing issues with safety and management practices at major UK rail stations, particularly Euston, which has been criticized for overcrowding and last-minute platform announcements.
AMD's open-source Linux graphics driver is blocked from adding HDMI 2.1+ support due to legal requirements from the HDMI Forum, affecting features like 4K@120Hz and 5K@240Hz for Radeon GPU users.
The HDMI Forum rejected AMD's proposal, suggesting users switch to DisplayPort, as confirmed by AMD's Linux engineer Alex Deucher.
The HDMI Forum's restrictions on public access to specifications since 2021 ensure quality but hinder open-source support, prompting AMD to consider alternative solutions.
HDMI Forum has rejected AMD's open-source driver for HDMI 2.1, leading to debates about the decision's impact on HDMI quality and the potential benefits for DisplayPort.
Critics claim the rejection is protectionist, but note that most users may not be affected as they do not require HDMI 2.1 or use Linux.
The situation underscores frustrations with HDMI's dominance and raises discussions about DisplayPort and USB-C as potential alternatives.
Skip.tools, co-created by Marc, transpiles SwiftUI iOS apps into Kotlin Jetpack Compose apps, enabling the use of a single language for both iOS and Android.
Unlike other cross-platform tools, Skip generates genuinely native apps for both platforms without embedding a separate engine, ensuring platform-native controls and features.
After a year of development, Skip has released version 1.0, ready for production use, and includes support for popular frameworks like SQLite, Firebase, and Lottie.
Skip.tools has released version 1.0, enabling developers to build native iOS and Android apps from a single Swift codebase by transpiling SwiftUI into Kotlin Jetpack Compose.
