NoiseTools is a free, web-based tool that allows users to easily add various types of noise textures to images. It supports different noise algorithms like Perlin, Simplex, and Value, offering customization options for grain size, intensity, and blending modes. The tool provides a real-time preview of the effect and allows users to download the modified image directly in PNG format. It's designed for quick and easy addition of noise for aesthetic purposes, such as adding a vintage film grain look or creating subtle textural effects.
DrumPatterns.onether.com is a new website for creating and sharing drum patterns. Users can build rhythms using a simple grid-based interface, choosing different sounds for each element. Created patterns can then be shared via a unique URL, allowing others to listen, copy, and modify them. The site aims to be a collaborative resource for drummers and musicians looking for inspiration or seeking to easily share their rhythmic ideas.
HN users generally praised the drum pattern sharing website for its simplicity and usefulness. Several appreciated the straightforward interface and ease of creating and sharing patterns, finding it more intuitive than some established digital audio workstations (DAWs). Some suggested improvements like adding the ability to loop patterns, change tempo, and export in various formats (MIDI, WAV). Others discussed the technical implementation, wondering about the sound font used and suggesting alternative approaches like Web Audio API. The creator actively responded to comments, acknowledging suggestions and explaining design choices. There was also a brief discussion about monetization strategies, with affiliate marketing and premium features being suggested.
TranslateManga offers a free web-based tool to instantly translate manga. Users simply upload a manga page image, and the service automatically detects text bubbles, translates them into the chosen language, and overlays the translation onto the original image. It supports a wide range of languages and aims to make reading manga in any language accessible and effortless. The translated manga pages can then be downloaded for offline viewing.
HN users discussed the legality and ethics of TranslateManga, given that it translates and republishes manga without explicit permission from copyright holders. Some expressed concern about the potential for abuse and negative impact on the manga industry, while others argued that it provides valuable access to content otherwise unavailable to non-Japanese speakers. Technical discussion centered around the quality of the translations, with some praising its accuracy while others pointed out frequent errors and awkward phrasing. Several commenters also suggested alternative translation methods and tools, and debated the practicality of machine translation versus human translation for manga. The potential for the site to improve language learning was also mentioned. A few users questioned the site's monetization strategy and the long-term viability of the project.
DualQRCode.com offers a free online tool to create dual QR codes. These codes seamlessly embed a smaller QR code within a larger one, allowing for two distinct links to be accessed from a single image. The user provides two URLs, customizes the inner and outer QR code colors, and downloads the resulting combined code. This can be useful for scenarios like sharing a primary link with a secondary link for feedback, donations, or further information.
Hacker News users discussed the practicality and security implications of dual QR codes. Some questioned the real-world use cases, suggesting existing methods like shortened URLs or link-in-bio services are sufficient. Others raised security concerns, highlighting the potential for one QR code to be swapped with a malicious link while the other remains legitimate, thereby deceiving users. The technical implementation was also debated, with commenters discussing the potential for encoding information across both codes for redundancy or error correction, and the challenges of displaying two codes clearly on physical media. Several commenters suggested alternative approaches, such as using a single QR code that redirects to a page containing multiple links, or leveraging NFC technology. The overall sentiment leaned towards skepticism about the necessity and security of the dual QR code approach.
Habby is a minimalist digital bullet journal combining journaling and habit tracking. It offers a clean, distraction-free interface for daily note-taking and progress monitoring on personal habits. Users can create and track habits, write daily journal entries, and review their progress visually. The focus is on simplicity and ease of use, providing a streamlined approach to personal organization and self-improvement.
HN users generally praised Habby's simplicity and clean design, finding it a refreshing alternative to overly complex habit trackers. Several commenters appreciated the focus on privacy, with the app storing data locally. Some suggested potential improvements, such as customizable reminders, exporting data, and the ability to track more nuanced habits beyond simple checkmarks. The developer responded to several comments, indicating openness to feedback and future development. There was also a brief discussion comparing Habby to similar apps like Streaks.

HN commenters generally praised the simplicity and usefulness of the noise tool. Several suggested improvements, such as adding different noise types (Perlin, Worley, etc.), more granular control over noise intensity and size, and options for different blend modes. Some appreciated the clean UI and ease of use, particularly the real-time preview. One commenter pointed out the potential for using the tool to create dithering effects. Another highlighted its value for generating textures for game development. There was also a discussion about the performance implications of using SVG filters versus canvas, with some advocating for canvas for better performance with larger images.
The Hacker News post "Show HN: I built a tool to add noise texture to your images" linking to noisetools.vercel.app has several comments discussing the tool and its potential applications.
Many commenters praise the simplicity and effectiveness of the tool. One user appreciates the clean interface and how easy it is to use, directly comparing it favorably to Photoshop's noise filters, finding it quicker and more intuitive for this specific purpose. They particularly highlight the real-time preview as a valuable feature. Another commenter echoes this sentiment, emphasizing the speed and convenience compared to opening a full image editor. This user also suggests a potential improvement: the ability to upload an image for editing rather than relying solely on the provided examples.
Several users discuss potential use cases beyond simple aesthetic additions. One commenter mentions using noise for creating dithering effects, specifically for CNC milling. This sparks a brief discussion about different types of noise and their applications in various fields, including generating stipple patterns for laser engraving. Another user points out the value of adding noise for data anonymization, specifically mentioning blurring faces in images while preserving overall scene context.
Some technical feedback is also offered. One user suggests exploring WebGPU for potential performance improvements, though acknowledges the current browser support limitations. Another commenter questions the choice of sRGB color space, recommending linear color space for noise generation, arguing it leads to more perceptually uniform results. They explain that adding noise in sRGB can result in unwanted color shifts. This technical point sparks a small discussion about the complexities of color management in web applications.
A few commenters express interest in the underlying implementation details. One asks about the specific noise algorithms used, while another inquires about the front-end framework employed. The creator of the tool responds to some of these queries, clarifying technical choices and outlining future development plans, which include adding more noise types and potentially incorporating user-uploaded images. This interaction demonstrates a positive engagement between the creator and the Hacker News community.
