1. Reverse engineering Ticketmaster’s rotating barcodes
Link | Comments: 466 | Points: 1252
Article Summary: The author expresses frustration with TicketMaster’s SafeTix system, which uses a rotating barcode technology that cannot be saved, shared, or printed like traditional PDF tickets. This system, while marketed as a security feature to combat fraud and unauthorized resales, complicates the ticketing process by requiring a live internet connection at the event venue, potentially leaving attendees stranded if they cannot access their mobile tickets due to poor service. Through reverse engineering, the author discovers that the rotating barcodes are generated using standard cryptographic methods and could theoretically be duplicated or manipulated, questioning the effectiveness and customer-friendliness of TicketMaster’s technology. The article criticizes TicketMaster’s motivations, suggesting that the technology primarily serves to control ticket resale markets and gather user data, rather than genuinely improving customer experience or security.
Comments Summary: The comment thread discusses frustrations with Ticketmaster’s and AXS’s ticketing practices, highlighting issues such as their monopoly on resale markets, delayed payments to sellers, and restricted ticket transfers. One commenter noted that these companies could combat scams more effectively by opening their systems to third-party verification instead of maintaining a closed ecosystem that benefits them financially. Another commenter shared personal experiences with Ticketmaster’s restrictive policies, like withholding tickets until just before an event, complicating personal resales and refunds.
2. No more boot loader: Please use the kernel instead
Link | Comments: 227 | Points: 444
Article Summary: Red Hat is developing a new bootloader called nmbl to replace GRUB, aiming for a simpler, more secure system by utilizing the Linux kernel itself as the bootloader. GRUB, despite its versatility across various architectures, has become overly complex and less secure due to its duplicative nature with the Linux kernel, which is faster in feature development and security updates. The proposed nmbl system will use a unified kernel image loaded by the EFI stub, integrating the kernel, initramfs, and command line to streamline booting without redundant code. Red Hat is seeking community feedback on nmbl to refine and optimize its functionality for various use cases.
Comments Summary: In the discussion, participants evaluate the practicality and benefits of using the Linux kernel as a bootloader, noting it allows for operations like modifying the command line, dual-booting, and booting other EFI applications, which traditional UEFI setups may complicate. Some reminisce about simpler times when the kernel could directly boot from a floppy, highlighting the evolution and increased complexity in boot processes.
3. The Right Kind of Stubborn
Link | Comments: 166 | Points: 340
Article Summary: Persistence and obstinacy may seem similar as both involve relentless effort, but they differ fundamentally in approach and outcome. Persistent individuals adapt and listen to feedback, focusing on achieving goals with a flexible approach, whereas obstinate individuals cling rigidly to their initial ideas, often ignoring external input and alternative solutions. This distinction is crucial as persistence involves a complex interplay of energy, imagination, resilience, good judgment, and goal focus, leading to effective problem-solving. In contrast, obstinacy, often a simpler, more reflexive resistance to change, can hinder progress, especially in complex situations.
Comments Summary: The comment thread explores the nuanced differences between persistence and obstinance, focusing on the underlying motivations and impacts of each trait. Discussions highlight how persistent individuals allow room for error and growth, driven by a blend of internal and external motivations, whereas obstinate individuals seek constant external validation, often driven by insecurity. Moreover, there’s an observation on how obstinacy might appear as confidence in public perceptions, influencing how individuals are received despite the practical outcomes of their approaches.

5. Entering text in the terminal is complicated
Link | Comments: 146 | Points: 220
Article Summary: Editing commands in the terminal can be challenging due to inconsistencies across different programs, with some not supporting basic features like arrow keys, while others use libraries like readline or have their own custom input systems. Readline, widely used in many programs, offers functionalities like history search and easy navigation, but not all applications implement it due to reasons like dependency concerns or licensing issues. Some systems, like Python on macOS, use alternatives like libedit, which offers fewer features, and others have custom systems that may provide enhanced autocomplete and history management. Understanding the type of input system in use—whether it’s basic, readline, libedit, or custom—can significantly ease the use of command line interfaces, making them more predictable and user-friendly.
Comments Summary: The comment thread explores various advanced uses and manipulations of terminal input and output, including using stty to customize terminal behaviors, experiments with capturing keyboard and mouse inputs, and creative ways to visualize and interact with terminal data. Participants share innovative scripts and personal projects that enhance interactive experiences in terminals, demonstrating the versatility and depth of terminal programming.
6. Anna’s Archive Faces Millions in Damages and a Permanent Injunction
Link | Comments: 99 | Points: 204
Article Summary: Anna’s Archive, a search engine for pirated books, faces legal action from OCLC for scraping and distributing data from its WorldCat database, leading to a lawsuit for hacking and damages exceeding $5 million. Despite the lawsuit, Anna’s Archive has not responded in court and continues to operate, recently switching to a new domain to potentially evade U.S. jurisdiction. OCLC seeks a default judgment, including monetary damages and injunctive relief to prevent further data scraping and distribution. The case highlights the ongoing struggle between copyright holders and digital piracy platforms, with Anna’s Archive exemplifying the challenges of enforcing copyright laws against elusive online entities.
Comments Summary: The comment thread expresses skepticism and criticism regarding the lawsuit against Anna’s Archive, questioning the legitimacy of the claimed damages and the classification of web scraping as a cyberattack. Commenters suggest that the damages, including costs for infrastructure and employee efforts, are exaggerated and speculate that there might be ulterior motives linked to the book industry influencing the lawsuit.
