Why do railway tracks have crushed stones alongside them?

  • Railway tracks have crushed stones alongside them, known as ballast, which serve a crucial role in maintaining tracks and ensuring the safety of trains.
  • Ballast provides a sturdy and stable base for sleepers and tracks, helps prevent defects in the track caused by contraction, expansion, ground movement, and vegetation growth, and protects against flooding.
  • Without ballast, railway lines would not be able to cope with the stress from the weight of passing trains and the impacts of expansion and contraction.

Industry Reactions

  • Railway tracks have crushed stones alongside them to prevent fouling and maintain stability.
  • Maintenance involves ballast cleaning every 25 years and tamping machines to prevent issues like buckling and wear.
  • Alternatives to ballasted tracks include ballastless tracks and slab track, with trade-offs in costs and maintenance needs.

Anything can be a message queue if you use it wrongly enough

  • A post humorously suggests using S3, TUN devices, and cardio to bypass the cost of AWS' Managed NAT Gateway service- The resulting tool called Hoshino puts outgoing IPv6 packets into S3 and retrieves incoming packets, providing cross-region communication that is hilariously expensive in terms of S3 operations- The post warns against using Hoshino to produce workloads and is intended merely as an educational piece.

Industry Reactions

  • Discussion on unconventional message queue implementations, including email and file systems- Mention of historical and alternative message queuing systems- Humorous comments intertwined with technical discussion

High prices make textbook 'piracy' acceptable to most students

  • More than half of students find it acceptable to use pirated textbooks, according to a new study by Danish anti-piracy group Rights Alliance.
  • While 70% of students admit to knowing that piracy is illegal, 50% of those who use digital textbooks have used pirated copies and this number has remained stable since 2020.
  • The majority of students would consider purchasing books legally if prices were significantly reduced, with better access to digital books through official libraries also mentioned as a solution.

Industry Reactions

  • Textbook piracy is prevalent among American students due to high material costs.
  • Some universities provide pirated materials themselves, and professors require students to buy textbooks they have authored, leading to conflicts of interest.
  • Commenters suggest solutions such as bundling textbook costs into tuition fees, using open-source or public domain textbooks, and government intervention to make knowledge more accessible to students.

WFH – Watched from Home: Office 365 and workplace surveillance creep (2022)

Apple Virtualization Framework

  • Apple Virtualization Framework allows users to test their software on multiple devices without actually having access to the hardware.
  • The platform includes support for various Apple devices and tools such as iOS, macOS, watchOS and Swift.
  • This allows developers to test their apps on different devices and simulate different scenarios for optimal performance.

Industry Reactions

  • Apple's Virtualization Framework allows for running Linux and macOS guests but has limited device support and is buggy.
  • Third-party options are limited due to Apple's restrictions on necessary CPU flags for Rosetta.
  • Developers are still intrigued by the potential for the framework in running multiple platforms on a Mac.

Lung cancer pill cuts risk of death by half

  • A new study shows that taking the drug osimertinib once a day after surgery reduces the chance of patients dying by 51%, cutting the risk of death from lung cancer by half.
  • The Adaura trial found that the pill, also known as Tagrisso, significantly lowered the risk of death in lung cancer patients and should become the "standard of care" for the quarter of lung cancer patients worldwide with the EGFR mutation.
  • Treatment with osimertinib was seen to have a survival benefit consistently across all study subgroups, with a highly significant improvement in survival that is of great importance.

Industry Reactions

  • Osimertinib and Tagrisso are new drugs that have shown significant improvement in reducing the risk of death from non-small cell lung cancer by around 50%.
  • Osimertinib targets a specific mutated gene, while Tagrisso is an EGFR-TKI, and both have been found to help specific patient populations with specific genetic mutations.
  • Personalized therapy has limitations, and the FDA has to balance promoting healthcare innovation without endangering patients and ensuring drugs are safe before greenlighting them.
