Running extra fiber optic cable during initial installation, even if it seems excessive, is a highly recommended practice. Future-proofing your network infrastructure with spare fiber significantly reduces cost and effort later on. Pulling new cable is disruptive and expensive, while having readily available dark fiber allows for easy expansion, upgrades, and redundancy without the hassle of major construction or downtime. This upfront investment pays off in the long run by providing flexibility and adaptability to unforeseen technological advancements and increasing bandwidth demands.
Pi-hole v6.0 is a significant update focusing on enhanced user experience and maintainability. It features a redesigned web interface with improved navigation, accessibility, and dark mode support. Under the hood, the admin console now uses Vue 3 and the API utilizes PHP 8.1, modernizing the codebase for future development. FTL, the DNS engine, also received updates improving performance and security, including DNSSEC validation enhancements and optimized memory management. While this version brings no major new features, the focus is on refining the existing Pi-hole experience and laying the groundwork for future innovation.
Hacker News users generally expressed excitement about Pi-hole v6, praising its improved interface and easier setup, particularly for IPv6. Some users questioned the necessity of blocking ads at the DNS level, citing browser-based solutions and the potential for breakage of legitimate content. Others discussed alternative solutions like NextDNS, highlighting its cloud-based nature and advanced features, while some defended Pi-hole's local control and privacy benefits. A few users raised technical points, including discussions of DHCPv6 and unique privacy addresses. Some expressed concerns about the increasing complexity of Pi-hole, hoping it wouldn't become bloated with features. Finally, there was some debate about the ethics and effectiveness of ad blocking in general.

HN commenters largely agree with the author's premise: running extra fiber is cheap insurance against future needs and troubleshooting. Several share anecdotes of times extra fiber saved the day, highlighting the difficulty and expense of retrofitting later. Some discuss practical considerations like labeling, conduit space, and potential damage during construction. A few offer alternative perspectives, suggesting that focusing on good documentation and flexible network design can sometimes be more valuable than simply laying more fiber. The discussion also touches on the importance of considering future bandwidth demands and the increasing prevalence of fiber in residential settings.
The Hacker News post "If you get the chance, always run more extra network fiber cabling" generated a lively discussion with several insightful comments. Many commenters strongly agreed with the premise of running extra fiber, emphasizing the relatively low cost of the cable itself compared to the labor involved in installation, making it a worthwhile investment for future-proofing.
Several users shared anecdotes reinforcing this point. One commenter recounted a situation where pre-running extra fiber saved them significant time and money when they unexpectedly needed to expand their network infrastructure. Another highlighted the difficulty and expense of retrofitting fiber in older buildings, emphasizing the wisdom of over-provisioning during initial construction.
A few commenters offered practical advice on implementing this strategy. Suggestions included labeling cables clearly, using high-quality cable for longevity, and considering future bandwidth needs. One commenter specifically recommended using OM5 fiber for its higher bandwidth capacity, while another cautioned against going overboard and advocated for a balanced approach based on reasonable future needs. This commenter argued against running exorbitant amounts of fiber "just because," and instead recommended a sensible approach to over-provisioning.
The discussion also touched on the importance of proper documentation. Commenters stressed the need for accurate records of cable runs, including detailed diagrams and labeling, to facilitate future maintenance and upgrades. This was highlighted as particularly important in larger or more complex installations where tracking cable runs can become difficult.
Some users also mentioned the potential benefits of dark fiber – unused optical fiber – for future expansion or leasing opportunities. This was presented as another argument for installing more fiber than immediately necessary.
Finally, a few comments addressed the broader context of network planning, emphasizing the importance of considering not just fiber but also other aspects of network infrastructure like conduit space and power distribution. These commenters argued for a holistic approach to network design, considering all interconnected elements.
Overall, the comments on Hacker News strongly supported the idea of running extra fiber cabling whenever possible, citing cost savings, future-proofing, and the challenges of retrofitting. The discussion provided practical advice on implementation and highlighted the importance of documentation and a comprehensive approach to network planning.
