| 1. | Build your own decision model(nishtahir.com) |
| 454 points by softwaredoug 3 days ago | 102 comments | permalink | |
tl;dr: Instead of generating tokens autoregressively, you can build a fast "decision model" by running a single forward pass on an LLM (e.g., Qwen3-1.7B) and masking logits to only allowed answer tokens (A-E), picking the highest probability. Benchmarked on CommonsenseQA, this yields ~59% accuracy (62% after finetuning), but the raw probabilities are badly miscalibrated—overconfident in the 0.9+ range. Temperature scaling (T≈3.8) flattens the distribution so confidence scores actually match empirical accuracy. | |

tl;dr: In 1996, the author wrote a 2D rigid-body physics simulation in GFA BASIC on an Atari ST that became the vehicle system in the original Grand Theft Auto. For its 30th anniversary, they've recreated it in JavaScript ("Motion Lab") with playable Car, Ship, and Brick modes. The post details the design: a proper rigid-body core with torques (uncommon in games then) layered with a deliberately simplified, non-physical tyre model that applies velocity-proportional resistance along and across each wheel's heading to produce convincing car-like handling. | |

tl;dr: A former Apple designer prototypes the "Lightbulb Computer," a projector-plus-camera device in an Edison bulb form factor that projects interactive interfaces onto real-world surfaces—recipes on counters, maps on tables, controls near smart home devices—and responds to voice and pointing gestures. The author pitches it as a social, ambient alternative to both screen-based and face-worn (AR/VR) computing, arguing projector and computer vision tech is nearly ready for a consumer version, with privacy handled via on-device processing and hardware camera guards. | |

| 5. | Talorys – A self-hosted personal AI agent on Cloudflare's free tier(github.com) |
| 323 points by rociiu 3 days ago | 150 comments | permalink | |
tl;dr: Talorys is an open-source single-user AI assistant that deploys to your own Cloudflare account via `npx create-talorys@latest`, using Pages, Workers, SQLite-backed Durable Objects, and Workers AI (GLM-4.7-flash) — all on the free tier with no external servers or telemetry. It offers chat, persistent memory, tasks/notes/projects, and scheduled automations via Durable Object alarms, with non-AI features continuing to work if the daily Workers AI quota is exhausted. Data stays in your Cloudflare account, and the installer is idempotent with built-in update, backup, and password-reset commands. | |

tl;dr: A self-described "low-level coder" who thrives on deep understanding of machine details (assembly, cycle-counting, performance optimization) laments that the industry's shift toward LLM-driven development and high-level abstraction has devalued their expertise. They can't use LLMs effectively because their mind requires reinventing concepts from first principles, and they find being redirected to an AI instead of consulted as an expert deeply alienating. What started as career anxiety has escalated to considering disability, as hobbyist retrocomputing communities are also increasingly dominated by LLM enthusiasts. | |

tl;dr: Cloudflare is acquiring the entire Deno team, which will shift focus from the standalone Deno runtime and Deno Deploy to a shared platform built around Cloudflare Workers and Durable Objects. Deno will receive bug fixes and security updates for one more year before development ends (remaining open source for community continuation), while Deno Deploy shuts down in six months with migration support to Workers. JSR and rusty_v8 work will continue under Cloudflare, with the team's new focus being "celld," a distributed application model targeting AI agent workloads. | |

| 9. | I would like the value of my home to rise, while my property taxes fall(conversableeconomist.com) |
| 275 points by colinprince 3 days ago | 683 comments | permalink | |
tl;dr: Several US states have recently slashed property taxes on owner-occupied homes, shifting the burden onto commercial property, state funds, and sales/income taxes—effectively converting a local service-financing tool into redistributive taxation. Homeowners, despite seeing major post-COVID wealth gains, are driving this backlash because property taxes function as wealth taxes requiring cash from asset-rich, income-poor owners (especially older voters). The ironic result: lower property taxes will push home prices even higher, further enriching current owners while worsening affordability for future buyers and weakening local government funding for schools and police. | |

tl;dr: REA is a tool that connects to coding agents (via `npx rea-agents@latest setup`) to let them reverse-engineer software by inspecting binaries, scripts, and runtime behavior. The agent can read disassembly, decompiled code, and loaded scripts, then explain or rebuild functionality in plain English. Demos include recovering Chrome's dinosaur game acceleration rule (0.001 per update, max 13) and Windows Calculator's percentage logic (which differs between +/− and ×/÷ operations). | |

tl;dr: WallHop is a replacement for the defunct 12ft.io paywall bypass tool. Users can skip paywalls by prefixing URLs with a slash, using an iPhone Shortcut, a bookmarklet, or raw/API endpoints. The creator recommends subscribing to news sites you read regularly, pitching WallHop as a tool for one-off articles. | |

tl;dr: Oxide Computer raised a $445M Series D led by Eclipse, with participation from existing investors (USIT, Riot, Jane Street) and new backers Atreides Management and strategic investor AMD. The company recently became profitable (paying income tax on operations) but needs the capital to fund inventory and manufacturing for a backlog that significantly exceeds supply. The round builds on their Series C goal of de-risking the company to ensure longevity and independence while scaling production. | |

tl;dr: Programmers wrongly accept AI coding tools because they consider programming merely functional rather than creative, but the author argues programming is art—even mundane code involves aesthetic decisions, and great innovations (like the author's Deferred abstraction) emerge from the contemplation of tedious work. Using AI to automate away mundane programming eliminates the practice opportunities needed to develop craft and achieve occasional moments of greatness, just as it would in writing, music, or visual art. Programmers should resist AI encroachment the way other creative professionals do. | |

| 461 points by g-b-r 4 days ago | 317 comments | permalink | |
tl;dr: Telegram Desktop (through 7.2.8) had a vulnerability where clicked `tg://` links were passed between instances over a local socket using a semicolon-delimited format that wasn't escaped, allowing command injection. Attackers could chain this with the internal `interpret:` URI scheme—originally used for publishing releases—which reads arbitrary files and sends them to a chat without authorization checks, enabling exfiltration of session files and full account takeover. Fixed in 7.2.9 (CVE-2026-107181) by removing `interpret://` and properly escaping the socket protocol. | |
