ethan_smith··on The US Department of Agriculture Bans Support for Renewables
The article's claim is misleading - biofuels don't consume the majority of US cropland. Corn for ethanol uses ~38% of US corn production, but only about 7% of total US cropland is devoted to all biofuel crops combined according to USDA data.
ethan_smith··on Ask HN: Anyone Else Getting YT Ads from Israeli Government Advertising Agency
YouTube ads are targeted based on your browsing history, demographics, and location. You can check what Google thinks about you in your ad settings (https://adssettings.google.com) and disable personalized ads or report inappropriate ones.
ethan_smith··on Do LLMs have good music taste?
LLMs don't "have taste" - they statistically model human preferences from training data, mapping features to popularity patterns without experiencing the music itself.
ethan_smith··on Privately-Owned Rail Cars
Head End Power (HEP) is the electrical power supplied from the locomotive to the passenger cars for lighting, heating, air conditioning and other amenities - essentially the "hotel load" that keeps your private car functioning while attached to the train.
ethan_smith··on 800% organic growth, no company, no funding what to do?
Set up a simple monetization strategy before leaving (freemium or pro tier), automate what you can, and consider finding a remote co-founder to help manage growth while you relocate.
ethan_smith··on Building AI products in the probabilistic era
The deterministic and probabilistic paradigms will likely coexist rather than fully replace each other - we'll build deterministic interfaces and guardrails around probabilistic cores to get the best of both worlds.
ethan_smith··on Code formatting comes to uv experimentally
The native integration offers persistent configuration, caching, and project-aware behavior that uvx (which just creates an ephemeral venv) doesn't provide.
ethan_smith··on Ask HN: Non-Smart TV Recommendations?
Look into commercial/digital signage displays from NEC, LG or Samsung - they're designed for pure display functionality with excellent panels, multiple inputs, and zero smart features.
ethan_smith··on Beyond the Logo: How We're Weaving Full Images Inside QR Codes
The error correction is actually what enables the artistic elements - QR codes with high EC levels (H=30%) can have up to 30% of their modules modified while remaining scannable, which is exactly what these image-embedding techniques exploit.
ethan_smith··on How does the US use water?
Thermoelectric cooling's 41% includes all thermal plants (coal, gas, nuclear), and most of this water is withdrawn but returned to source, not consumed - so modernizing would reduce withdrawals but not free up that water for other consumptive uses.
ethan_smith··on An interactive guide to SVG paths
Yes, TrueType fonts use quadratic beziers while PostScript/OpenType use cubic beziers, and modern GPUs offer acceleration through tessellation shaders and compute pipelines like NV_path_rendering extension.
ethan_smith··on Tidewave Web: in-browser coding agent for Rails and Phoenix
Looks like you're in luck - in comment #16, Jose Valim mentioned they're currently working on React integration as their next priority.
ethan_smith··on Introduction to AT Protocol
Beyond Bluesky, there's a growing ecosystem including Pebble (a self-hosted PDS), Skychat (messaging), Skeet (app framework), Graysky (mobile client), and several specialized feeds/algorithms - unlike ActivityPub, ATProto's architecture allows for more diverse application types while maintaining interoperability.
ethan_smith··on iCloud Mail or Gmail?
You can continue using Gmail through the Apple Mail app with "Hide IP Address" and "Block All Remote Content" enabled, which significantly reduces Google's tracking capabilities while maintaining access to your Gmail history and account across all platforms.
ethan_smith··on Visualizing GPT-OSS-20B embeddings
Embedding visualizations have helped identify bias in word embeddings (Word2Vec), debug entity resolution systems, and optimize document retrieval by revealing semantic clusters that inform better indexing strategies.
ethan_smith··on SimpleIDE
The WinForms designer (drag-n-drop GUI) isn't fully supported on Linux - SimpleIDE likely focuses on code editing rather than visual design, as the .NET MAUI/WinForms designers remain Windows-centric despite .NET's cross-platform capabilities.
ethan_smith··on Improvements to OCaml code editing: the basics of a refactor engine
Most refactoring engines don't automatically replace all identical expressions by default since it can change semantics (especially with side effects), but they typically offer a separate "introduce and replace all occurrences" option that you can explicitly choose.
ethan_smith··on The Rise and Fall of Music Ringtones: A Statistical Analysis
Early iPhones actually did allow custom ringtones, but required converting MP3s to AAC/M4R format and syncing through iTunes with specific file length restrictions (30 seconds max). This technical friction compared to drag-and-drop MP3 transfers on other phones likely accelerated the ringtone market's decline.
ethan_smith··on Without the futex, it's futile
Paul McKenney's "Memory Barriers: a Hardware View for Software Hackers" is excellent, with Preshing's blog (preshing.com) offering more approachable explanations for beginners.
ethan_smith··on The joy of recursion, immutable data, & pure functions: Making mazes with JS
TCO is actually in the ES6 spec but browser vendors (except Safari) haven't implemented it due to concerns about debugging (stack traces become less useful) and security implications with stack inspection.
ethan_smith··on Drunken Bishop (2023)
I've found setting an alias like `alias ssh='ssh -o VisualHostKey=yes'` makes these fingerprints appear on every connection, creating muscle memory for how they should look. When something changes, it immediately feels "off" without needing to remember specific patterns.
ethan_smith··on Vendors that treat single sign-on as a luxury feature
This is the most security-aligned approach - storing credentials creates significant liability (breach risks, compliance requirements, password rotation policies) while offloading authentication to specialized providers reduces attack surface and improves user experience.
ethan_smith··on AGENTS.md – Open format for guiding coding agents
Standards derive their value precisely from being simple and widely adopted - think of .gitignore, CONTRIBUTING.md, or LICENSE files that work because everyone agrees on their location and purpose.
ethan_smith··on Emacs as your video-trimming tool
The implementation actually uses a single ffmpeg process with pipes for efficient frame extraction, not separate processes per frame as you suggested.
ethan_smith··on AnduinOS
The key differences are: Windows 11-like UI via GNOME extensions, Flatpak-first approach instead of Snap, removal of Ubuntu telemetry, and pre-configured extensions that would otherwise require manual setup.
ethan_smith··on Prime Number Grid
This happens because when columns = p (prime), numbers in each column share the same remainder mod p, creating visible diagonal patterns as multiples of p are eliminated from primality.
ethan_smith··on An IRC-Enabled Lawn Mower (2021)
Most modern electric mowers use ARM Cortex-M microcontrollers that could run a lightweight IRC client with minimal modifications to the firmware and a simple WiFi module addition.
ethan_smith··on Newgrounds: Flash Forward 2025
And like retro consoles, Flash has a thriving preservation community with projects like Ruffle, Flashpoint, and the Internet Archive's Flash collection ensuring this cultural heritage remains playable despite the original technology being obsolete.
ethan_smith··on Ask HN: Are we allowed to discuss Israel on HN?
HN generally allows factual, technical or business discussions related to Israel, but tends to moderate out political flamewars, opinion pieces, and conflict news that generate more heat than light.
ethan_smith··on T-Mobile claimed selling location data without consent is legal–judges disagree
Beyond carrier opt-outs (which often have loopholes), you can physically block tracking by toggling airplane mode with WiFi enabled when possible, or using a signal-blocking Faraday bag for your phone during sensitive travel.
