Show HN: LogMerge – View multiple log files in a merged view https://ift.tt/LYbjOqR

Show HN: LogMerge – View multiple log files in a merged view Hey HN! I needed a tool to view multiple log files in a merged view, and easily filter based on the specified fields. Spent a good amount of time searching, but couldn’t find any open source tool that quite did what I wanted. So, ended up building a custom solution instead (I would appreciate suggestions on tools that have similar functionality). I don't know much about GUIs (most all my PC based utilities are CLI) - but I did have the following: - I know enough Python to spot obviously wrong things - Some knowledge of how to make programs performant in general - ... and tokens to burn :) GitHub : https://ift.tt/J8Mo2xB Usage Video: https://youtu.be/37V_kZO2TLA Key Features: - Merge and display multiple log files in a single, chronologically ordered view - Live log monitoring with auto-scroll - Add files individually or discover them recursively with regex filtering - Plugin-based system to support any log format (easy to extend!) - Filtering: discrete values, numeric ranges, regex/text, and time-based queries - Color-coded file identification - Configurable columns and ordering - Built-in plugins for syslog, CANKing (CAN Bus monitoring tool), and another custom log format called dbglog. If you have any feedback or questions, let me know! Hope someone else finds it useful. https://ift.tt/J8Mo2xB July 26, 2025 at 04:23AM

Show HN: Price Per Token – LLM API Pricing Data https://ift.tt/5DhC2bN

Show HN: Price Per Token – LLM API Pricing Data The LLM providers are constantly adding new models and updating their API prices. Anyone building AI applications knows that these prices are very important to their bottom line. The only place I am aware of is going to these provider's individual website pages to check the price per token. To solve this inconvenience I spent a few hours making pricepertoken.com which has the latest model's up-to-date prices all in one place. Thinking about adding image models too especially since you have multiple options (fal, replicate) to use the same model and the prices are not always the same. https://ift.tt/mNpJ3P8 July 25, 2025 at 06:09PM

Show HN: Local Email Client for AI Horseless Carriages The AI Horseless Carriages article spurred a lot of conversation about how we should just be giving users the system prompt box [0], and we were pretty surprised that a bunch of email clients didn’t pop up following this pattern [1]. So we went ahead and created a local [2] email client that you can run that processes your inbox with your own handwritten rules. It lets you label and archive based on natural language rules. You can draft responses with your own drafting prompt, and there’s a “research sender” option that uses web search to get public info on a sender. You can customize any of the prompts to fit your needs. We’d love to hear what you think and PRs/issues are welcome!

Show HN: Kafka, the first AI employee (NEW SOTA ON GAIA BY 20%) https://ift.tt/Rh62LOi

Show HN: Kafka, the first AI employee (NEW SOTA ON GAIA BY 20%) Hi HN, I'm Gokhan, the founder of Brainbase Labs. Today we're releasing an early preview of our first generalist agent, Kafka. Kafka is the first AI employee, he comes with his own computer as well as his own email, phone and Slack so you can work with him just like you would with a regular employee. You can forward him emails, give him a call, tag him on Slack. We built Kafka as the basis for our other AI employees we will be releasing over the coming months. Kafka currently achieves 77.2% on the GAIA Level 3 benchmark, getting us closer to human performance at 87%. We've achieved this by creating a new type of planning algorithm called "structured planning" which allows Kafka to run very long term plans without getting sidetracked or hallucinating. Kafka can do some cool things, he can push code to AWS, direct its own commercial using Veo3 and do actual production tasks on Upwork/Fiverr. We're very keen to hear what HN thinks about Kafka, and how we can improve. Appreciate any feedback! https://ift.tt/Ywlb9zu July 23, 2025 at 10:21PM

Show HN: How Claude Code Improved My Dev Workflow https://ift.tt/LYaRVPb

Show HN: How Claude Code Improved My Dev Workflow I've been using Claude Code for the past month and it's transformed my productivity. Show HN: Title: A New Era for Software Development: AI Pair Programming Vs. Traditional Methods Today, let's dive deep into a topic that's revolutionizing the software development landscape - AI Pair Programming. By shedding light on the specific problems it solves, we will explore a real-life case study, and provide actionable insights to help you enhance your workflow. Firstly, let's understand the challenge. Traditional pair programming, while being highly beneficial, is often hindered by scheduling conflicts, differing skill levels, and varying coding styles. Here's where AI pair programming steps in. It leverages artificial intelligence to generate code suggestions, allowing developers to work more efficiently. Consider the case of CodeStream, a software startup. They adopted AI pair programming using GitHub Copilot. The results? Their development speed increased by 30%, and the number of bugs decreased by 25%. They also witnessed a significant improvement in code quality. This case study clearly illustrates the transformative power of AI in software development. So how can you incorporate this cutting-edge method into your workflow? Here are three actionable insights: 1. *Embrace AI tools:* Start by integrating AI-based coding assistants like GitHub Copilot or Kite into your development environment. These tools provide real-time, context-aware code suggestions, significantly reducing your coding time. 2. *Upskill:* AI pair programming is not about replacing human developers. It's about augmenting their abilities. Therefore, it's crucial to upskill and stay updated with AI advancements in your field. 3. *Continuously Test:* While AI tools can write code, they're not infallible. Regularly testing the AI-generated code ensures optimal performance. Now, where does the Keychron K8 Pro Keyboard fit into this workflow? For a start, it's a tool that enhances programming efficiency. With its hot-swappable keys and customizable layouts, developers can create shortcuts for frequently used coding commands, thereby streamlining their workflow. Its Bluetooth 5.1 feature allows for smooth What tools are you using to improve your coding workflow? Disclosure: Post contains affiliate links. July 23, 2025 at 02:57AM

Show HN: Compass CNC – Open-Source Handheld CNC Router https://ift.tt/ge2A4IV

Show HN: Compass CNC – Open-Source Handheld CNC Router Hey HN, I am Cam, and for the past two years I have been working on Compass, an open-source handheld CNC router that brings computer precision to woodworking while keeping the user directly involved in the process. The idea started as my senior design project at UC Berkeley, with the goal of making a more approachable CNC machine—standard CNC machines are expensive, bulky, and remove you from the tactile “maker” experience. Compass solves that by combining a handheld router with real-time robotic assistance. You move the router roughly along a design path, and Compass uses four optical flow sensors (like in computer mice) and a 3-axis motion system to auto-correct for precision cuts. What is different about Compass: - Open source: All plans, firmware, and CAD files are available on GitHub. - Affordable: The DIY build costs ~$600 in parts, and I am selling kits for <$800. - No external markers: The sensing technology allows for positioning without external markers, so no setup or consumables required. - Portable: Fits in a backpack and is not limited by a fixed work envelope. We recently completed our first beta program and have just launched V1 kits for pre-order. You can find more info and the launch video at the listed URL.

Show HN: Lotas – Cursor for RStudio https://ift.tt/b1ueHNF

Show HN: Lotas – Cursor for RStudio Hey HN! We’re Jorge and Will from Lotas ( https://www.lotas.ai/ ), and we’ve built an AI coding assistant into RStudio (think Cursor for RStudio). RStudio is used by about 2 million data scientists and academics, but they currently lack a coding assistant within their IDE. Developers in other environments benefit from tools like Cursor and Windsurf, but R users don’t have any equivalent tools to speed up their workflow. Since ~80% of R programmers prefer to use RStudio over other IDEs like VSCode to write R code, we figured a tool like this one could be quite useful. Both of us were PhD students at Harvard. Jorge was in the biophysics program and Will was in the biostatistics program where most people used RStudio every day. We saw how integrated code assistants were taking off in other IDEs, but we noticed that the RStudio integrations were still lagging far behind. Many R users were copying and pasting code from ChatGPT to build their workflows, and this was clearly slow and fragile. To bring the Cursor-like experience to RStudio users, we built Rao ( https://www.lotas.ai/ ): a fork of RStudio with an embedded AI assistant that is aware of the user’s local context (both files and variable environment), can read and write files, can run code or commands, and can interpret textual or visual output. It works with any of the file formats already in RStudio (R, notebooks including RMDs and QMDs, Python, Stan, etc.), allowing R programmers to iteratively perform entire data analyses inside their preferred IDE. Other AI data science tools are either (1) built on the web or in environments people don’t already use, (2) are completely focused on python notebooks, or (3) are weak package-based assistants with limited functionality. Rao is exactly like the RStudio IDE that millions of data scientists already use, but it incorporates a powerful AI assistant and works with all the standard file types. You can download Rao at https://ift.tt/QiAdNqB , watch our demo on the homepage ( https://www.lotas.ai/ ), and work through some example use cases on our GitHub ( https://ift.tt/VQYrmLj ). We have a one-week free trial (no card required) and provide 500 queries/month for $20/month after that. We’d love to hear feedback from the HN community to make Rao as useful as possible! You can reach us at founders@lotas.ai. P.S. We have zero data retention (ZDR) agreements with OpenAI and Anthropic, but we currently recommend users do not input sensitive or regulated data like PHI into Rao until we sign BAAs with both model providers.

Show HN: The missing link of a bookstore's tech stack https://ift.tt/GsPca0o

Show HN: The missing link of a bookstore's tech stack Hi HN! I built Bookhead because I used to work as a bookseller and I wasn't happy with the software options when I decided to sell my own collection online (with the hopes of one day growing so I can open my own brick & mortar). So I decided to make my own bookselling app...a classic hacker distraction. Bookhead has two main parts: 1. an inventory management app that allows a bookseller to list their books anywhere they want to sell books (like Squarespace, Biblio, eBay, Shopify (coming soon!), etc) 2. an e-commerce platform with a CMS for selling books and letting a store control their online brand I have a very exciting roadmap that I'm not ready to fully reveal, but it's all based on books. I'm building a sorta Zapier-like platform for independent booksellers. Everything is so fragmented and disconnected, which makes it hard for booksellers to do their work. I'm hoping to change that. I have a blog post that lays out my vision here: https://ift.tt/FnsXVC8 The current iteration is like "data engineering as a service for books." A book is a powerful thing. I'm hoping to give a bookstore everything they need to sell books online. Inventory, e-commerce, marketing, etc. It's a crowded market but I've had fun making the bookselling app that I believe should exist. If you know any booksellers, please let them know about this! I'm onboarding my first customer right now and the biggest bottleneck is the other bookselling software providers, despite my intention to collaborate instead of compete. It's frustrating to wait for two weeks for a point of sale provider to setup an integration. It's almost like they don't care about their customers. Some providers even require ethernet cables for their software...still partying like it's 1999. Perfect for early-adopter booksellers frustrated with current tech who understand the power of automation. I'm currently looking for funding so I can focus on this full-time. My biggest problem right now is time (aka money) because I have to sell my time to make rent etc, and can't focus on this project like I need to. I've gotten good validation from booksellers and other technically savvy folks in the industry (I've heard from two different companies that they've considered building something like this), so I believe I have something valuable. I'm not interested in funding from somebody who doesn't share my love for books or doesn't support my mission: help people use technology to promote literature. I believe that literature is one of humanity’s most prized creations, and we can use technology as a tool to keep this gift alive. Please email me at sam@bookhead.net if you know of booksellers who might want to be an early adopter, or know of any funding opportunities that might be a good fit. https://bookhead.net/ July 21, 2025 at 12:19AM

Show HN: Transform passive YouTube watching into active learning https://ift.tt/1xmbMq4

Show HN: Transform passive YouTube watching into active learning I've been self-learning from YouTube for years—everything from coding to design to business skills. But I kept hitting the same wall: YouTube learning has no structure. Your knowledge gets scattered across random playlists, you're passively consuming content without real retention, and when you're confused, there's nobody to ask. I built Notetube to fix this by layering organizational tools with AI to create a proper learning system: Organizational layer: Build structured collections by topic/course/skill, visualize your learning progress with dashboards, create and track your learning goals AI layer: Automatically generates detailed notes (3000+ words for 1 hour of content) and summaries, identifies key moments with timestamps, creates personalized quizzes for retention testing, and provides a chat interface for instant help when concepts aren't clear ...plus additional features like timestamped note-taking, but I'll keep this brief.

Show HN: I built library management app for those who outgrew spreadsheets https://ift.tt/alOyzt8

Show HN: I built library management app for those who outgrew spreadsheets I've been working on librari.io for the past several months and just launched the beta version. The Problem: I have 500+ books across multiple rooms in my house and was desperately looking for an app to manage them properly. Most library management apps are either too basic or designed for institutional libraries with rigid workflows that don't fit personal use. What I Built: - Multiple libraries: manage collections in different locations - Location tracking - remember exactly which shelf each book is on - Loan management - track books you've lent to friends - Custom fields & tags - store any additional book info the way YOU think about them - Reading progress tracking - dates, duration, personal ratings - Modern UI/UX - clean & actually enjoyable to use Current Status: - Beta version live - Working on improving the responsiveness of the app and addressing initial user feedback Would love feedback! Especially curious about: - What features would make YOU actually use a library management app? - UI/UX feedback always welcome - Any book collectors here who'd be interested in beta testing? Looking forward to your thoughts! Thank you in advance. https://www.librari.io/ July 19, 2025 at 12:58AM

Show HN: Tips for getting great Text2Cypher outputs from LLMs for Graph RAG https://ift.tt/LGstZR6

Show HN: Tips for getting great Text2Cypher outputs from LLMs for Graph RAG For folks working on Graph RAG and trying to get LLMs to generate Cypher queries, I ran some experiments on the LDBC dataset and wrote a blog post about it (code is available in the link shown at the end of the post). I've been trying to answer a burning question of mine that I've had for a while now: when doing Text2Cypher, are LLMs better at interpreting graph schemas in JSON, XML or YAML? (Spoiler alert, the format barely matters, it's all to do with context engineering and retaining only the relevant parts of the graph schema in the prompt). Results on the latest LLMs are really good! The post also contains some other tips on graph schema design: I think we're in an age now where we need to design graph schema for both LLMs and humans. If you're working on Text2Cypher in any way, hope some of these ideas and experiments are useful! https://ift.tt/9ABHZ1n July 18, 2025 at 07:22PM
