Show HN: Travel Hacking Toolkit – Points search and trip planning with AI
Summary
The repository **travel‑hacking‑toolkit** provides an AI‑driven workflow for finding award‑flight and cash‑price options, comparing points versus cash, and managing loyalty balances. It integrates two AI back‑ends—OpenCode and Claude Code—via Model Context Protocol (MCP) servers that expose real‑time travel APIs (Skiplagged, Kiwi, Trivago, Ferryhopper, Airbnb, Seats.aero, Duffel, SerpAPI, etc.). A setup script (`scripts/setup.sh`) configures the chosen AI, creates API‑key files, installs dependencies, and optionally installs the skills directory system‑wide. Skills are markdown files containing endpoint docs, curl examples, jq filters, and workflow guidance; they are stored under `skills/` and symlinked to `~/.config/opencode/skills/` or `~/.claude/skills/`. Core data files (`alliances.json`, `hotel‑chains.json`, `partner‑awards.json`, `points‑valuations.json`, `sweet‑spots.json`, `transfer‑partners.json`) encode airline alliances, hotel programs, award relationships, valuation ranges, high‑value redemption windows, and credit‑card transfer ratios. The typical workflow queries award availability (Seats.aero), cash prices (SerpAPI/Skiplagged), portal value (dynamic CPP rates), balances (AwardWallet), and generates booking links (Seats.aero/Duffel). The project is MIT‑licensed.

Herbie: Automatically improve imprecise floating point formulas
Summary
Herbie is a tool that automatically rewrites floating‑point expressions to improve numerical accuracy. Users start it with `racket -l herbie web` (or `herbie`) and interact through a browser UI. An example (`sqrt(x+1)‑sqrt(x)`) shows Herbie increasing accuracy from 53.2 % to 99.7 % and sometimes reducing runtime.
The tutorial demonstrates fixing bug 208 in JavaScript’s `math.js` complex square‑root implementation. The core computation:
```js
var r = Math.sqrt(x.re*x.re + x.im*x.im);
0.5 * Math.sqrt(2.0 * (r + x.re))
```
is extracted, with `x.re` and `x.im` treated as independent float inputs and each branch (non‑negative/negative `x.im`) submitted separately. Input ranges are limited (e.g., `x.im ≥ 0`, `x.re` up to 1.79e308).
Herbie generates several alternatives; the most accurate (≈84.6 %) inserts an `if` to avoid cancellation and replaces `sqrt` with `Math.hypot`. The resulting code snippet includes the conditional and uses `hypot` for a more stable distance calculation. Users can translate alternatives to target languages via the UI and repeat the process for other branches.

Community Discussion
The feedback expresses uncertainty about the tool’s capabilities, questioning whether reformulations can be limited to non‑branching forms and seeking clarification on whether reported speedups refer to latency or throughput. Users are skeptical about the relevance of improvements when operating with values already scaled to a typical numeric range, and they doubt the accuracy gains shown in examples, noting apparent inconsistencies. The commentary also calls for clearer explanations of the problems addressed, suggests integrating robust accuracy enhancements into the language rather than relying on a separate library, and warns that reliance on such a tool might introduce additional errors.

What changes when you turn a Linux box into a router
Summary
Turning a Linux host into a functional Wi‑Fi router requires seven kernel and userspace configurations:
- **Enable IP forwarding** (`net.ipv4.ip_forward=1` via `/etc/sysctl.d/10-forward.conf`) so packets destined for non‑local addresses reach the FORWARD hook.
- **Create a bridge (`br0`)** and add the wired NIC (`eth0`) directly and the wireless NIC (`wlan0`) indirectly via `hostapd` (`bridge=br0`). The bridge unifies L2 segments, presenting a single LAN address.
- **Install nftables rules** on the FORWARD chain (default drop) to allow established/related inbound traffic from WAN (`eth0`) and new/established outbound traffic from LAN (`br0`).
- **Activate conntrack** so stateful inspection can classify packets as `new`, `established` or `related`, enabling the minimal rule set.
- **Define NAT/masquerade** in the POSTROUTING chain (`oifname "eth0" masquerade`) to translate private LAN addresses to the router’s public IP.
- **Run dnsmasq** on `br0` to provide DHCP leases and DNS resolution, announcing the router’s IP as gateway and DNS server.
- **Run hostapd** to put the Wi‑Fi card into AP mode, broadcast SSID, manage authentication, and attach the interface to `br0`.
These steps collectively configure L3 routing, L2 bridging, firewalling, NAT, and wireless access point services on a multi‑homed Linux system.

Community Discussion
Comments emphasize that enabling IPv4 forwarding on Linux instantly opens the system to routing, requiring explicit firewall configuration to prevent unintended exposure. Users criticize certain container platforms for activating forwarding without securing the traffic, noting that this can unintentionally make a host an open router. Several contributors share personal experiences, ranging from abandoning complex firewall setups in favor of dedicated appliances to recalling early, self‑taught networking projects that fostered long‑term technical confidence. The overall tone combines caution about default policies with nostalgic pride in hands‑on learning.
The house is a work of art: Frank Lloyd Wright
Community Discussion
The comments express strong admiration for Frank Lloyd Wright’s work, highlighting Fallingwater and the Currier Museum’s Wright houses as must‑see architectural experiences that evoke emotional, even reverent, responses. The Zimmerman House is praised for its warm aesthetic, while the Kalil/Usonian Automatic house is noted for its concrete gray tone and more relatable, attainable feel despite deviating from Wright’s typical warmth. Visitors also recommend related sites such as Taliesin and House on the Rock. There is a shared lament that contemporary, high‑priced housing often lacks the design quality of Wright’s legacy.
Fake Fans
Summary
Chaotic Good Projects is a digital‑marketing agency that offers “narrative,” user‑generated‑content (UGC), fan‑page, and brand‑media services for musicians. Its core tactic is to create large numbers of fake fan accounts that post content, simulate trends, and seed “viral” TikTok clips, aiming to shape discourse and drive organic user engagement. The agency’s client roster spans mainstream pop acts (Dua Lipa, Shawn Mendes, Justin Bieber) and indie‑level artists such as Cameron Winter, Geese, Dijon, Mk.gee, Laufey, Wet Leg, Oklou, and Jane Remover. Founders Jesse Coren and Andrew Spelman describe posting “hundreds of times” to amplify a single release, using quote‑based videos that tie songs to everyday experiences. The article highlights how this model shifts promotional labor from artists to agencies, intensifies the algorithmic attention economy, and blurs the line between genuine fan communities and manufactured hype. It also notes the broader industry shift from traditional gatekeepers to short‑form platform virality, and reflects on the personal challenges musicians face in balancing touring, budgeting, and authentic audience connection.
