FilePizza allows for simple, direct file transfers between browsers using WebRTC. It establishes a peer-to-peer connection, eliminating the need for an intermediary server to store the files. The sender generates a unique URL that they share with the recipient. When the recipient opens the URL, a direct connection is established and the file transfer begins. Once the transfer is complete, the connection closes. This allows for fast and secure file sharing, particularly useful for larger files that might be cumbersome to transfer through traditional methods like email or cloud storage.
Multiple vulnerabilities were discovered in rsync, a widely used file synchronization tool. These vulnerabilities affect both the client and server components and could allow remote attackers to execute arbitrary code or cause a denial of service. Exploitation generally requires a malicious rsync server, though a malicious client could exploit a vulnerable server with pre-existing trust, such as a backup server. Users are strongly encouraged to update to rsync version 3.2.8 or later to address these vulnerabilities.
Hacker News users discussed the disclosed rsync vulnerabilities, primarily focusing on the practical impact. Several commenters downplayed the severity, noting the limited exploitability due to the requirement of a compromised rsync server or a malicious client connecting to a user's server. Some highlighted the importance of SSH as a secure transport layer, mitigating the risk for most users. The conversation also touched upon the complexities of patching embedded systems and the potential for increased scrutiny of rsync's codebase following these disclosures. A few users expressed concern over the lack of memory safety in C, suggesting it as a contributing factor to such vulnerabilities.
This blog post details the author's successful implementation of a FujiNet network adapter for a Tandy Color Computer 3. After encountering initial difficulties with a pre-assembled device, they opted to build their own using a kit. This involved careful soldering and troubleshooting, particularly with the SD card interface. Ultimately, they achieved a stable connection, enabling them to access a virtual floppy drive and remotely transfer files to the CoCo 3 via a local network, significantly enhancing its capabilities. The author emphasizes the improved speed and convenience compared to traditional floppy disks and expresses satisfaction with the FujiNet's performance.
Several commenters on Hacker News express excitement about the FujiNet project, particularly its potential to simplify retro-computing networking. Some discuss their experiences with similar setups, highlighting the challenges of configuring vintage hardware for modern networks. The ability to use SD cards for virtual floppy disks and the promise of future features like BBS access and online multiplayer gaming generate considerable interest. Several users inquire about the hardware requirements and compatibility with various MSX models, demonstrating a practical interest in utilizing the technology. Some express nostalgia for older networking methods and debate the authenticity versus convenience trade-off. There's also discussion of alternative solutions like the MSX-DOS 2 TCP/IP driver, with comparisons to FujiNet's approach.

HN commenters generally praised FilePizza's simplicity and clever use of WebRTC for direct file transfers, avoiding server-side storage. Several appreciated its retro aesthetic and noted its usefulness for quick, informal sharing, particularly when privacy or speed are paramount. Some discussed potential improvements, like indicating transfer progress more clearly and adding features like drag-and-drop. Concerns were raised about potential abuse for sharing illegal content, along with the limitations inherent in browser-based P2P, such as needing both parties online simultaneously. The ephemeral nature of the transfer was both praised for privacy and questioned for practicality in certain scenarios. A few commenters compared it favorably to similar tools like Snapdrop, highlighting its minimalist approach.
The Hacker News post discussing "Peer-to-peer file transfers in the browser" (referencing the FilePizza project on GitHub) has a moderate number of comments, generating a discussion around the practicality, security, and historical context of the tool.
Several commenters express concerns about security, questioning the safety of transferring files directly between browsers without intermediary checks or safeguards. One user highlights the potential for unknowingly receiving malicious files disguised as something innocuous, while others point out the lack of built-in virus scanning or other protective measures. The discussion also touches upon potential legal implications, particularly regarding copyrighted material.
Some commenters discuss the practical limitations of browser-based P2P transfer, such as the requirement for both parties to be online simultaneously. They contrast this with the convenience of cloud storage services or file-sharing platforms that allow asynchronous transfer. The relatively low bandwidth available to browsers compared to dedicated applications is also mentioned as a potential bottleneck, especially for larger files.
Several commenters draw comparisons to older P2P technologies, recalling tools like Napster and the early days of file-sharing. Some express nostalgia for simpler times before centralized platforms dominated, while others analyze how FilePizza's approach differs technically from these predecessors. The discussion also delves into the historical context of similar projects, with some users referencing past attempts to build browser-based file-sharing tools and the challenges they faced.
One commenter suggests potential improvements, such as implementing end-to-end encryption to enhance security and privacy. Another explores the technical aspects of WebRTC, the underlying technology powering FilePizza, explaining how it enables direct communication between browsers. There's also mention of alternative approaches to P2P file transfer, including using distributed hash tables (DHTs) for more robust and scalable solutions.
A few commenters express appreciation for the simplicity and elegance of FilePizza, praising its minimalist design and ease of use. They acknowledge its limitations but see value in its direct and straightforward approach to file sharing.
Overall, the comments reflect a mixture of skepticism, nostalgia, and technical curiosity. While some appreciate the concept and execution of FilePizza, many raise valid concerns about its security and practicality in the current landscape of file transfer solutions. The discussion offers valuable insights into the complexities of browser-based P2P, highlighting both its potential and its challenges.
