Show HN: Put macros.menu/ in front of any restaurant menu URL I’ve been tracking my macros every day since January 1st. Weighing and measuring at home is a breeze but eating out is a total pain. I built this tool for myself but a lot of likeminded people have loved it. Please note macros are estimated by gen AI. Image menus not supported yet. https://macros.menu May 14, 2025 at 12:49AM

Show HN: GS-Base – A multifunctional database tool with Python integration https://ift.tt/yHgkdSG

Show HN: GS-Base – A multifunctional database tool with Python integration A wide range of possible use: from simple contact/inventory lists, photo albums to editing CSV/text files and processing (transforming, splitting, merging, normalizing) large, multi-GB data tables in various file formats. Text, Numeric, Long Text / Memo fields, Image / File fields; Code fields for code snippets with syntax highlighting for 16 programming languages. You can analyze, query and consolidate data, generate pivot tables, perform calculations, merges and joins with up to 256 million rows, 16K columns and 4GB+ files efficiently using even older PC's. Several filtering methods, searching for duplicates, for unique values and their frequencies, search-as-you-type, random and quartile searches, full-text searches, fuzzy searches. RegEx filtering of millions of records in seconds regardless of the number of the returned found records. Searching for file duplicates, finding similar photos/images, music and video files using any EXIF tags and multimedia (e.g. mp3/mp4) tags. Playing filtered lists of mp3's. Very fast data consolidation - you don't have to bother with permanent indices; internal indexes are created automatically whenever aggregation and binary lookup functions need them. Generating disk/folder listings and monitoring all file changes with searchable history of modifications. Mass-renaming, -copying and -deleting files based on filtered file listings. GS-Base can be installed on any portable storage device and used without performing any registry modifications. Fully offline - doesn't need internet connection. To move it to another computer you can simply copy the installation folder containing a few files. Questions and suggestions are welcome. https://ift.tt/dF9nNDa May 13, 2025 at 02:32AM

Show HN: Lumoar – Free SOC 2 tool for SaaS startups https://ift.tt/HErYJUv

Show HN: Lumoar – Free SOC 2 tool for SaaS startups We built Lumoar to help small SaaS teams get SOC 2-ready without paying thousands for Big 4 consultants or dealing with bloated compliance platforms. As a startup ourselves, we faced the usual issues: long security questionnaires, confusing audit requirements, and expensive tools that felt overkill. Lumoar is a simpler alternative: - Generate compliant SOC 2 policies automatically - Track your controls and progress in a clean dashboard - Upload evidence and get plain-language recommendations - Designed for engineers and founders, not compliance pros It's free to start — you can generate policies and explore the dashboard without a sales call or demo. Would love to hear what blockers you’ve faced with SOC 2 and what other frameworks you’re thinking about (e.g., ISO 27001, GDPR). All feedback is welcome. https://www.lumoar.com May 13, 2025 at 12:35AM

Show HN: AI-powered batch photo editor for real estate photographers https://ift.tt/kTPVgS7

Show HN: AI-powered batch photo editor for real estate photographers I got tired of repetitive editing tasks, so I built a tool that simplifies bulk edits using text prompts and AI workflows. Now I can quickly handle things like virtual staging, changing backgrounds, adding/removing objects, adjusting brightness and exposure, color corrections, boosting contrast and clarity, fixing distortions, batch color grading and much more! But most importantly, I can do this to all selected images, tens, hundreds or more. I'm particularly interested in feedback on the workflow and UI from photographers/editors who handle large volumes of images. I've increased the free plan credits to 40 so you can edit up to 40 images, if you'd like to help me trial it out. Otherwise I'm happy to answer any questions about the implementation or roadmap. https://4ditor.com/ May 9, 2025 at 06:38AM

Show HN: Hackergrep.com – search Hacker News for tech jobs https://ift.tt/BAeZ3C4

Show HN: Hackergrep.com – search Hacker News for tech jobs Hey HN, I built https://hackergrep.com and I think it's ready for some attention. What is it: I wanted a fast, flexible, and focused job search tool to find new tech jobs and I didn't see anything that really fit my needs, so I built this app because you can just do things. HackerGrep indexes several recent threads on HackerNews and combines the results into a feed matching your desired search filter criteria. The system can send you daily email updates when new search results for your queries are available; opt-in search query emails are sent for 30 days and then automatically stopped. New job alert emails are batched and sent daily, so you'll get one email per alert you configure until you unsubscribe or the 30 days are up. Key features: > no banner ads / clutter. > it's free to use. > no accounts/logins needed. > advanced search syntax and full-text search. > can notify you about new jobs matching your queries via email. > the search and alert emails always show the most recent results first. (To report bugs, suggest parser/logic improvements, offer me a job, or just say hi, etc, you can find my contact info on the https://ift.tt/U9InYh8 page) You can try it from any web browser. It's optimized for desktops or tablets with a reasonable screen size but should function anywhere. https://hackergrep.com https://hackergrep.com May 10, 2025 at 11:42PM

Show HN: PLAttice, for assembling structures much larger than the 3D printer bed https://ift.tt/DFct1ar

Show HN: PLAttice, for assembling structures much larger than the 3D printer bed Struts, nodes, and pins are reversibly assembled into fully 3D printed lattices, trusses, and tree-like structures spanning up to a few meters. I used the system to build a stand for an overhead table lamp which supports a ~1 m cantilevered arm using a tensioned floor-to-ceiling column. If you want to give it a try, find the *.stl files at the bottom of the page; figure ~1 kg of PLA and ~1 day of print time per meter of box truss; pay attention to print orientation; plz respect the license; and definitely print the pin trimming jig. https://ift.tt/gP5UXeZ May 11, 2025 at 01:48AM

Show HN: Limits.fyi – See what you are getting out of all your AI subscriptions https://ift.tt/6eZKXif

Show HN: Limits.fyi – See what you are getting out of all your AI subscriptions Hey HN, I've personally been having a hard time keeping track of all the changes to AI subscriptions these days. Sama is always tweeting about ChatGPT usage limits being improved as they add more GPUs, nobody knows how many Claude messages you get in a day, and Windsurf just recently updated their pricing plan. It's becoming increasingly difficult to get a clear and transparent view of what you're actually getting with each subscription. This becomes especially frustrating when you run into those annoying “no more remaining message” popups right in the middle of a coding session. I've also noticed many developers suffer from what I've started calling "query anxiety”, this is when a person is always worried about hitting their usage limits, so they just end up not using these models when they actually need them. That's why I created limits.fyi which lets you view and compare usage limits for all the popular AI subscriptions in one place. You can: - See exactly what usage limits come with each plan - Filter by specific models to find which subscriptions give you access - Compare prices to find the best value for your needs - Discover new services you might not have known about I try and keep the data up-to-date, and welcome user submissions. If you notice changes or have new information, you are encouraged to contribute using the submission feature at the bottom of the page. Check it out here: https://www.limits.fyi/ I'd love to hear your thoughts and suggestions on how to make this more useful. https://www.limits.fyi/ May 9, 2025 at 12:08AM
