Vietnam has enacted Decree No. 342, which amends the national Advertising Law and will take effect on February 15, 2026. This decree aims to increase consumer protection and combat illegal online advertising. Key provisions include a mandatory 5-second wait before video and animated ads can be skipped, with static ads requiring immediate cancellation. Platforms must provide clear and easy methods for users to close ads and report violations, and must also offer ways for users to opt out of seeing inappropriate advertisements. The decree also imposes stricter regulations on advertisements for 11 categories of products and services that impact environmental and human health, such as cosmetics, food, medical supplies, and pharmaceuticals.
HN users expressed a range of reactions to Vietnam's new ad regulations. Some viewed the ban on unskippable ads as a positive step, with one commenter suggesting that if an ad cannot be compelling within 5 seconds, it's unlikely to be effective. Others, however, were skeptical, predicting that platforms would compensate by displaying a higher volume of shorter, skippable ads, potentially leading to a more annoying user experience. Several commenters also pointed out that companies might adjust their ad strategies, such as showing ads in succession. The discussion also touched upon the broader implications of advertising, with one user questioning the societal impact of ad-incentivized addictive platforms and another considering the potential for increased VPN usage into Vietnam. The accuracy of the title (a typo in "Vietnam") was also a point of discussion for several users.

The author expresses a dramatic shift in their perspective on AI's capability to replace developers, attributing this change to their experience with Claude Opus 4.5. Previously skeptical, the author now believes AI agents can indeed replace developers entirely, citing Opus 4.5's ability to deliver on the promise of AI for coding. The author details building several applications, including a Windows image conversion utility, a screen recording/editing tool, an AI posting utility for a small business, and an order tracking/routing app, all with significant assistance from Opus 4.5. The key observation is Opus 4.5's ability to achieve most tasks on the first try, iterate and fix errors autonomously, and even handle complex backend integrations like Firebase and Facebook authentication with minimal human intervention.
The author also introduces a custom VS Code agent prompt designed to optimize code for LLMs rather than humans, prioritizing model reasoning, regeneration, and debugging. This prompt emphasizes simple entry points, explicit code, minimal coupling, and linear control flow, arguing that human readability is less critical when the AI handles all development work. While acknowledging the speed and ease with which these applications were built, the author also expresses a sense of exhilaration and a touch of existential dread about their lifelong learning now becoming trivial for a computer, while also encouraging others to "make things" faster than ever before.
Several commenters echoed the author's sentiment regarding Opus 4.5's significant leap in capability, particularly its independent decision-making and ability to execute plans and solve problems in a tight feedback loop. Users highlighted that while Opus 4.5 excels at executing clearly defined problems, its performance in complex, large-scale production environments remains an open question. There's a recognition that Opus 4.5 dramatically lowers the barrier to entry for individuals to build applications, especially for personal or hobbyist projects, but some voiced concerns that it might lead to an explosion of "slop apps" with questionable utility or quality.
A recurring theme in the discussion is the distinction between AI augmenting developers and replacing them. While acknowledging the impressive speed and leverage Opus 4.5 provides, some users emphasized that aspects like edge case testing, security audits, maintainability, and nuanced architectural decisions still require human judgment. Concerns were raised about the production-readiness of AI-generated code, with some commenters noting that AI solutions can sometimes be overly complicated or less maintainable than human-crafted ones. The author's own admission of "80% confidence" in security was cited as evidence that AI currently exposes rather than closes competence gaps in critical areas.

The article "Stop Doom Scrolling, Start Doom Coding: Build via the terminal from your phone" by rberg27 outlines a DIY method for coding remotely from a smartphone. The "Doom Coding" approach involves using a 24/7 internet-connected computer, a smartphone, Tailscale for secure remote access, Termius as a mobile terminal client, and Claude Code for assistance. The setup guide, requiring only 5 minutes, enables users to code from anywhere with an internet connection, as demonstrated by the author's experience coding a prototype in Philadelphia from Taiwan. The repository will be updated with comparisons of mobile coding tools.
The Hacker News discussion reveals mixed reactions to the "Doom Coding" concept. Some users express skepticism, questioning its necessity and productivity compared to using a laptop, with one commenter stating, "Just because you can doesn’t mean you should." Others find the idea intriguing and practical for situations like commuting, with users already experimenting with similar setups using tools like tmux and various VPNs. Security concerns were raised regarding the potential exposure of identifiers. A recurring point of discussion is the efficiency of coding on a phone versus a laptop, with some users preferring traditional methods or alternative uses of downtime like exercise and rest. The article's reliance on a paid subscription and a continuously running computer was also noted as a potential drawback compared to simpler, existing solutions like Termux.

Volkswagen is returning to physical buttons in its vehicle interiors, as demonstrated by the refreshed ID. Polo. This marks a significant shift away from the capacitive and touchscreen controls found in its current models. The new design features a full suite of physical buttons and switchgear on the steering wheel and dashboard for functions like cruise control, music, temperature, and fan speed. While initially appearing on the European-market ID. Polo, this new cockpit design may be introduced to other VW electric models in the US, potentially including a refreshed ID.4.
Commenters largely welcomed Volkswagen's return to physical buttons, citing that touchscreens are a needless distraction for drivers. Several users pointed out that the aviation industry, with its extensive research into cockpit design, still relies on physical buttons for critical controls, suggesting that cost savings and aesthetics, rather than driver safety, are the primary drivers for automakers removing buttons. Some expressed concern about the potential for overly complex button layouts, while others hoped Tesla would follow suit and reintroduce physical gear shifters and turn signal stalks. There was also a sentiment that some manufacturers copied Tesla's button-removal strategy without considering its original context of aiming for a driverless future.

The author details their decision to self-host a media library using Jellyfin and WireGuard on a Hetzner VPS, prompted by increasing prices and declining user experience on streaming services like Spotify. Dissatisfaction with Spotify's free tier restrictions, coupled with general trends of price hikes and UI degradations across various streaming platforms, motivated this shift. The setup involves a Hetzner VPS for the server, a Hetzner Storage Box for media storage, Jellyfin as the open-source media server, and WireGuard for secure remote access.
The technical implementation includes configuring WireGuard to establish secure tunnels for accessing the media server from home (via a router integration) and on the go (via mobile devices). Docker Compose is used to manage the deployment of both WireGuard and Jellyfin, with Jellyfin accessing media directly from the mounted storage box. The author concludes that while self-hosting offers benefits like control and privacy, it requires significant effort and may not be a direct replacement for the vast libraries and convenience of commercial streaming services for the average user.
Commenters largely agree with the author's motivations for self-hosting, citing privacy benefits, ownership of media, and dissatisfaction with how streaming platforms treat artists. Several users share their own self-hosting setups (e.g., Navidrome, Tailscale, Immich) and mention similar choices in media servers and VPN solutions. A significant point of discussion revolves around the economics of self-hosting versus streaming, with some arguing that streaming remains more cost-effective for accessing broad content, while others highlight the ethical implications of supporting artists through direct purchases. The practicalities of music discovery and mobile streaming for self-hosted libraries are also raised as challenges.
