Show HN: A Path-Based Data storage/retrieval web service to prevent crawling I listed my email on GitHub, and it got collected and used without my consent... To prevent this, I created a simple service using Django and PostgreSQL. As you can see when you access the site, you can save data by specifying a path. Think of it as a global key-value storage designed simply to prevent crawling. The data is not stored in an encrypted form, so please do not save sensitive information. Thank you. P.S.: Yes, I am a Faker's fan. https://hideonbush.com/ July 31, 2024 at 04:40AM

Show HN: 10x cheaper GitHub Actions on your AWS account https://ift.tt/vSWAbi2

Show HN: 10x cheaper GitHub Actions on your AWS account I'm Surya and I'm super excited to announce WarpBuild's new capabilities. WarpBuild provides drop-in replacements for Github hosted runners that are faster and cheaper. WarpBuild got its first customers from our launch on HN last year and I'm excited to show our newest offering: WarpBuild managed Github actions runners on your AWS account that are up to 90% cheaper than Github-hosted runners. In the last couple of months, we released a ton of new capabilities to speed up your workflows and save on costs like: (1) BYOC: run Github actions in your AWS account, in ~5 mins. (2) Managed unlimited Github caches. (3) Static IPs for allowlisting. (4) Flexible runner and disk configurations. (5) Spot instances, arm64 and x86-64 runners. This has been a top ask from our users, and this is even cheaper than self-hosting on k8s using `actions-runner-controller`, while significantly improving job queuing times. We are rather unique in the breadth and depth of the product we offer. This is another capability that we think moves the ecosystem forward, including `action-debugger` via ssh, fast MacOS (M2 Pro) runners, CI analytics dashboards and more. We are making CI faster and cheaper for everyone. What are your biggest pain points with CI, and more broadly the release process? I'd love to learn more. https://ift.tt/KZh3uXo July 30, 2024 at 09:39PM

Show HN: I made a tool to easily transform and manipulate your JSON data Hey NN, I've create a tool that allows you to easily manipulate and transform json data. After looking round for something to allow me to perform json to json transformations I couldn't find any easy to use tools or libraries that offered this sort of functionality without requiring learning obscure syntax adding unnecessary complexity to my work or the alternative being manual changes often resulting in lots of errors or bugs. This is why I built JSON Transformer in the hope it will make these sort of tasks as simple as they should be. Would love to get your thoughts and feedback you have and what sort of additional functionality you would like to see incorporated Thanks! :) https://ift.tt/ZtX2KWz (Link in case the other url doesn’t work) https://ift.tt/ZtX2KWz July 30, 2024 at 11:25PM

Show HN: ChainFactory – Run Structured LLM Inference with Easy Parallelism https://ift.tt/cQqTsDt

Show HN: ChainFactory – Run Structured LLM Inference with Easy Parallelism Hi HN! Disclaimer: I submitted another post about ChainFactory a few days ago. Here's what has changed since: - Added hash based caching of auto-generated prompts and masks. - Did some internal restructuring and cleanup. - Updated the order in which README doc introduces concepts and terminology. Posting this again because honestly, I am kinda puzzled about what to add/fix/change due to having 0 users and no genuine feedback. By genuine feedback, I mean feedback from strangers who do not have a social pressure to be polite and pull punches. Please take a look if you find this interesting and leave a comment. If you think it's an deranged or stupid idea not worth your time, please at least leave a 'no' - I'd still be delighted as it's an honest opinion. Thanks a lot! PS: Is it okay to post updates and changes at regular intervals? https://ift.tt/unTfZWe July 30, 2024 at 07:18AM

Show HN: How I wrote a LaTeX paper without writing any LaTeX Stempad is an online scientific text-editor. I built it because I wanted a way to do fast scientific writing with just my keyboard, and LaTeX wasn't cutting it. I recently launched the ability to export Stempad documents to LaTex. I tested it by rewriting part of a paper I found online (Metabolic scaling in small life forms by Marc E. Ritchie & Christopher P. Kempes) and exporting it. You can try the editor and export yourself using the post url. The export button is on the top right of the page.

Show HN: ThinkPost – split-panel note taking & brainstorming app for devs https://ift.tt/Su5TLDv

Show HN: ThinkPost – split-panel note taking & brainstorming app for devs ThinkPost is an Interactive split-panel diagramming, draggable block-based note-taking, and brainstorming tool. I developed ThinkPost as a side project for few months now. Basic idea is parallel streaming of ideas. It's a desktop web app with a very scaled down mobile version just for support. Whole my career I had been working with startups and specifically early stage ones, and it's a big responsibility to devise a feature on our own, think deeply about it in different streams (logically, security, re-usability, platform APIs etc.) and even present distilled part of it to stakeholders (Often times non technical people). Even now I run backend/infra/mobile/qa/customer support/integrations for a healthcare startup, so stakes are high. There's a lot of self brainstorming in multiple streams and then there's also distillation process. I couldn't really work with single page notepads for that streaming process. We should be able to note down in split-panels, so there's space for parallel ideas. Many note-taking apps today single-paged have high-think-threshold (windows notepad/apple notes have very low-think-threshold), you have to think before you write in them, so not a good option for quick ideas. So built a platform specifically for everyone who can parallel stream ideas in split panels Textually (low-think-threshold), write as they like), Diagrammatically, Code-wise or even Quick Maths. And also move the idea blocks across panels or within! or Open a new tab if you want more! I'm personally a massive user of my app because I plan everything at my current job via this app, run meetings, self-brainstorm features, study requirements, visualize code-ideas, an develop this when I get time as well. All completely free. Might run ads later. https://thinkpost.io - Try! no login needed. More comprehensive introduction: https://ift.tt/LDTPyms... https://thinkpost.io July 28, 2024 at 09:49PM

Show HN: Preprocessor I've been working 4 years now https://ift.tt/bUIh6tV

Show HN: Preprocessor I've been working 4 years now Hey there, I'm here today to share with you a software I've been working on for 4 years now. I'm not full time dedicated to it, as I need to make a living. My inspiration to develop it came when I started using Sass for real in production. I really appreciated the hierarchy of nesting rules instead of the way CSS vanilla used to do. The obvious nesting rules was easy to read and understand just by looking at. That was something I personally admirated very much. I wondered why there was no HTML preprocessors as revolutionary as there is for CSS and JavaScript. All popular preprocessors for HTML have one thing in common. All replace the angle brackets by something else (usually identation) and then add some functionalities on top of it. If the symbols for markups are a problem to the experience of developing a visual structure, just replacing it for something else doesn't fix the problem. You are just changing the character of marcation for another. With that in mind, I started Pretty Markup. Not just replacing the clutter of angle brackets by something else, but removing it completely. Very much inspired by Sass. No special characters needed, except by the quotes. The project still in its early stage, but its already useable. I reached a point where it has a stable base to work. Now, I'm plannig the layer of features that will make it usefull and revolutionary as Sass and TypeScript. Its important to note that I didn't started directly in Pretty Markup. I had a previous package called htmlpp-com-github-mopires. Yes, terrible name, but it was a start. Later a decided to make it more professional and with a friendly name. You can give it a shot by having NodeJS and installing it with: npm install pretty-markup I created a syntax hightlighter for VS Code to attract more devs to it. You can use it by searching "pretty markup" on the extensions tab. Now, it's the first one. The next step will be a package to create a basic starter project. Something like the good old create-react-app. Any feedback, suggestion or even a contribution about anything is very welcome. Thank you very much for your attention, Matheus PS: The package available in runkit is very old(and I don't know how to update it there), I do not recommend you to test there. https://ift.tt/3KLmGYX July 23, 2024 at 10:44PM

Show HN: Patchwork – Open-source framework to automate development gruntwork https://ift.tt/ZIxejtV

Show HN: Patchwork – Open-source framework to automate development gruntwork Hi HN! We’re Asankhaya and Rohan and we are building Patchwork. Patchwork tackles development gruntwork—like reviews, docs, linting, and security fixes—through customizable, code-first 'patchflows' using LLMs and modular code management steps, all in Python. Here's a quick overview video: https://youtu.be/MLyn6B3bFMU From our time building DevSecOps tools, we experienced first-hand the frustrations our users faced as they built complex delivery pipelines. Almost a third of developer time is spent on code management tasks[1], yet backlogs remain. Patchwork lets you combine well-defined prompts with effective workflow orchestration to automate as much as 80% of these gruntwork tasks using LLMs[2]. For instance, the AutoFix patchflow can resolve 82% of issues flagged by semgrep using gpt-4 (or 68% with llama-3.1-8B) without fine-tuning or providing specialized context [3]. Success rates are higher for text-based patchflows like PR Review and Generate Docstring, but lower for more complex tasks like Dependency Upgrades. We are not a coding assistant or a black-box GitHub bot. Our automation workflows run outside your IDE via the CLI or CI scripts without your active involvement. We are also not an ‘AI agent’ framework. In our experience, LLM agents struggle with planning and rarely identify the right execution path. Instead, Patchwork requires explicitly defined workflows that provide greater success and full control. Patchwork is open-source so you can build your own patchflows, integrate your preferred LLM endpoints, and fully self-host, ensuring privacy and compliance for large teams. As devs, we prefer to build our own ‘AI-enabled automation’ given how easy it is to consume LLM APIs. If you do, try patchwork via a simple 'pip install patchwork-cli' or find us on Github[4].

Show HN: Pairing LLM code generation with traditional templates https://ift.tt/Ca8RPW3

Show HN: Pairing LLM code generation with traditional templates Hi, I’ve been exploring Claude 3.5 code generation abilities for a while and it looks like it can generate more consistent code than other models. However it would still be unmaintainable if you ask it to write a lot of code and it still sucks at system design. So, I’ve been playing around the idea of using the code repository with a template for directory layout and infrastructure, then adding the repository information to Claude and asking it to generate code. It seems that it works, if I pass the structure of some OpenAPI based backend it can update the API definition and implementation pretty consistently. Take a look at the PoC and please share your thoughts about this! I wanted to see if someone else is working on similar idea, I’m open for a chat! https://ift.tt/NzCMm9d July 25, 2024 at 12:14AM

Show HN: Unsearch, an open source alternative to Google Chrome Sync I use several browsers between college, work and home and I like to have them synced so I can find websites I've searched for in a browser when I don't have access to it or access my bookmarks.

So I'm building an open source cross-browser manager for browsing activity. I would love to hear your thoughts on this concept, and if you have any questions or suggestions, please let me know. https://ift.tt/CHf4a8E July 24, 2024 at 10:48PM

Show HN: React Native Finisher Kit That'll Automate All the Complex Stuff https://ift.tt/dN93tyL

Show HN: React Native Finisher Kit That'll Automate All the Complex Stuff Hey HN, I've been automating mobile builds since 2017, publishing a course on mobile automation back then. Over the years, I’ve configured Mobile CI/CD for various companies using Bitrise, Codemagic, GitHub Actions – over and over again. To simplify this repetitive process, I’ve created a React Native "finisher kit" that automates Mobile CI/CD setup. Here’s what it offers: - Initial setup with monorepo support, multiple environments, unified configuration, testing set up, features like Push or iOS Live Activities… - Easy app creation for App Stores + Fully automated code signing, building, deployment, - Single place for configuration (AWS), reusable for local development, builds and deployment either locally or in the cloud, - A seamless system to manage configurations for Apple, Fastlane, Google, and more… It allows you to create your Mobile CI/CD with any of these providers with a single CLI command and keep it up-to-date. Switch between providers just by changing the config. It supports both React Native CLI projects and Expo. I built it to save time and reduce the complexity of mobile app development, hoping it will be as helpful for you as it has been for me. I’d love to get your feedback and thoughts. Thanks!

Show HN: OpenDataCapture an electronic data capture platform for data collection https://ift.tt/kVGwd92

Show HN: OpenDataCapture an electronic data capture platform for data collection Hi HN, We're the Douglas Neuroinformatics Platform[1], and we've been working on Open Data Capture, a web-based electronic data capture (EDC) platform for continuous clinical and research data collection. You can use it to administer instruments (like forms and interactive tasks) either in-person or remotely. The platform is based on a fundamentally longitudinal data model. Unlike other EDC platforms, which are centered around the concept of a study with rigid timepoints, Open Data Capture is designed for continuous data capture. Data is associated with a given session, which includes metadata such as date, time, and mode (i.e., in-person or remote). We've designed the system around the core restriction that many hospital institutions demand that data remain on-premise, while clinician-researchers often want to evaluate clients outside the institution with research questions. This has resulted in our innovative gateway concept, where assigned remote assessments are pushed onto an internet accessible service, and responses are encrypted in-place with HPKE[2] until the backend pulls them into the backend database. This makes the deployment firewall-friendly provided you can launch a minimal VPS or VM host somewhere globally accessible. We're also a big fan of making things easy to deploy, so we supply a docker-compose stack which can bring up a demo instance easily to run locally. The platform is free, open source, and written in TypeScript, with a NoSQL database underneath. Users can write instruments in TypeScript using a type-safe declarative form system (with native i18n support built in) or wrap and integrate completely arbitrary interactive tasks written in JavaScript (with optional support for TypeScript and JSX). Under the hood, this is based on dynamic imports and native ESM. There’s a browser-based IDE (the Instrument Playground) with live reloading and full Intellisense where you can try creating your own instruments. We have a local deployment going live at our institution and appropriately-licensed (free) instruments we're deploying here will be integrated directly into the codebase. Our future plans include expanding our instrument types to allow for binary data storage with an s3-like backend, and with abstractions for data types, like actigraphy, and MRI. Check it out on GitHub[3], try the Instrument Playground[4], or see the Live Demo[5]. Would love to hear everybody’s thoughts!

Show HN: How we leapfrogged traditional vector based RAG with a 'language map' https://ift.tt/3KFdsy8

Show HN: How we leapfrogged traditional vector based RAG with a 'language map' TL;DR: Vector-based RAG performs poorly for many real-world applications like codebase chats, and you should consider 'language maps'. Part of our mission at Mutable.ai is to make it much easier for developers to build and understand software. One of the natural ways to do this is to create a codebase chat, that answer questions about your repo and help you build features. It might seem simple to plug in your codebase into a state-of-the-art LLM, but LLMs have two limitations that make human-level assistance with code difficult: 1. They currently have context windows that are too small to accommodate most codebases, let alone your entire organization's codebases. 2. They need to reason immediately to answer any questions without thinking through the answer "step-by-step." We built a chat sometime a year ago based on keyword retrieval and vector embeddings. No matter how hard we tried, including training our own dedicated embedding model, we could not get the chat to get us good performance. Here is a typical example: https://ift.tt/IeFHCKf... If you ask how to do quantization in llama.cpp the answers were oddly specific and seemed to pull in the wrong context consistently, especially from tests. We could, of course, take countermeasures, but it felt like a losing battle. So we went back to step 1, let’s understand the code, let’s do our homework, and for us, that meant actually putting an understanding of the codebase down in a document — a Wikipedia-style article — called Auto Wiki. The wiki features diagrams and citations to your codebase. Example: https://ift.tt/AcqDyH0 This wiki is useful in and of itself for onboarding and understanding the business logic of a codebase, but one of the hopes for constructing such a document was that we’d be able to circumvent traditional keyword and vector-based RAG approaches. It turns out using a wiki to find context for an LLM overcomes many of the weaknesses of our previous approach, while still scaling to arbitrarily large codebases: 1. Instead of context retrieval through vectors or keywords, the context is retrieved by looking at the sources that the wiki cites. 2. The answers are based both on the section(s) of the wiki that are relevant AND the content of the actual code that we put into memory — this functions as a “language map” of the codebase. See it in action below for the same query as our old codebase chat: https://ift.tt/IeFHCKf... https://ift.tt/IeFHCKf... The answer cites it sources in both the wiki and the actual code and gives a step by step guide to doing quantization with example code. The quality of the answer is dramatically improved - it is more accurate, relevant, and comprehensive. It turns out language models love being given language and not a bunch of text snippets that are nearby in vector space or that have certain keywords! We find strong performance consistently across codebases of all sizes. The results from the chat are so good they even surprised us a little bit - you should check it out on a codebase of your own, at https://wiki.mutable.ai , which we are happy to do for free for open source code, and starts at just $2/mo/repo for private repos. We are introducing evals demonstrating how much better our chat is with this approach, but were so happy with the results we wanted to share with the whole community. Thank you! https://twitter.com/mutableai/status/1813815706783490055 July 19, 2024 at 12:10AM

Show HN: Blitzping – A far faster nping/hping3 SYN-flood alternative with CIDR https://ift.tt/RfdaEeh

Show HN: Blitzping – A far faster nping/hping3 SYN-flood alternative with CIDR I found hping3 and nmap's nping to be far too slow in terms of sending individual, bare-minimum (40-byte) TCP SYN packets; other than inefficient socket I/O, they were also attempting to do far too much unnecessary processing in what should have otherwise been a tight execution loop. Furthermore, none of them were able to handle CIDR notations (i.e., a range of IP addresses) as their source IP parameter. Being intended for embedded devices (e.g., low-power MIPS/Arm-based routers), Blitzping only depends on standard POSIX headers and C11's libc (whether musl or gnu). To that end, even when supporting CIDR prefixes, Blitzping is significantly faster compared to hping3, nping, and whatever else that was hosted on GitHub. Here are some of the performance optimizations specifically done on Blitzping: * Pre-Generation : All the static parts of the packet buffer get generated once, outside of the sendto() tightloop; * Asynchronous : Configuring raw sockets to be non-blocking by default; * Multithreading : Polling the same socket in sendto() from multiple threads; and * Compiler Flags : Compiling with -Ofast, -flto, and -march=native (though these actually had little effect; by this point, the bottleneck is on the Kernel's own sendto() routine). Shown below are comparisons between the three software across two CPUs (more details at the GitHub repository): # Quad-Core "Rockchip RK3328" CPU @ 1.3 GHz. (ARMv8-A) # +--------------------+--------------+--------------+---------------+ | ARM (4 x 1.3 GHz) | nping | hping3 | Blitzping | +--------------------+ -------------+--------------+---------------+ | Num. Instances | 4 (1 thread) | 4 (1 thread) | 1 (4 threads) | | Pkts. per Second | ~65,000 | ~80,000 | ~275,000 | | Bandwidth (MiB/s) | ~2.50 | ~3.00 | ~10.50 | +--------------------+--------------+--------------+---------------+ # Single-Core "Qualcomm Atheros QCA9533" SoC @ 650 MHz. (MIPS32r2) # +--------------------+--------------+--------------+---------------+ | MIPS (1 x 650 MHz) | nping | hping3 | Blitzping | +----------------------+------------+--------------+---------------+ | Num. Instances | 1 (1 thread) | 1 (1 thread) | 1 (1 thread) | | Pkts. per Second | ~5,000 | ~10,000 | ~25,000 | | Bandwidth (MiB/s) | ~0.20 | ~0.40 | ~1.00 | +--------------------+--------------+--------------+---------------+ I tested Blitzping against both hpign3 and nping on two different routers, both running OpenWRT 23.05.03 (Linux Kernel v5.15.150) with the "masquerading" option (i.e., NAT) turned off in firewall; one device was a single-core 32-bit MIPS SoC, and another was a 64-bit quad-core ARMv8 CPU. On the quad-core CPU, because both hping3 and nping were designed without multithreading capabilities (unlike Blitzping), I made the competition "fairer" by launching them as four individual processes, as opposed to Blitzping only using one. Across all runs and on both devices, CPU usage remained at 100%, entirely dedicated to the currently running program. Finally, the connection speed itself was not a bottleneck: both devices were connected to an otherwise-unused 200 Mb/s (23.8419 MiB/s) download/upload line through a WAN ethernet interface. It is important to note that Blitzping was not doing any less than hping3 and nping; in fact, it was doing more. While hping3 and nping only randomized the source IP and port of each packet to a fixed address, Blitzping randomized not only the source port but also the IP within an CIDR range---a capability that is more computionally intensive and a feature that both hping3 and nping lacked in the first place. Lastly, hping3 and nping were both launched with the "best-case" command-line parameters as to maximize their speed and disable runtime stdio logging. https://ift.tt/D4f2Bjb July 15, 2024 at 02:28PM

Show HN: Mandala – Automatically save, query and version Python computations https://ift.tt/FQIApHr

Show HN: Mandala – Automatically save, query and version Python computations `mandala` is a framework I wrote to automate tracking ML experiments for my research. It differs from other experiment tracking tools by making persistence, query and versioning logic a generic part of the programming language itself, as opposed to an external logging tool you must learn and adapt to. The goal is to be able to write expressive computational code without thinking about persistence (like in an interactive session), and still have the full benefits of a versioned, queriable storage afterwards. Surprisingly, it turns out that this vision can pretty much be achieved with two generic tools: 1. a memoization+versioning decorator, `@op`, which tracks inputs, outputs, code and runtime dependencies (other functions called, or global variables accessed) every time a function is called. Essentially, this makes function calls replace logging: if you want something saved, you write a function that returns it. Using (a lot of) hashing, `@op` ensures that the same version of the function is never executed twice on the same inputs. Importantly, the decorator encourages/enforces composition. Before a call, `@op` functions wrap their inputs in special objects, `Ref`s, and return `Ref`s in turn. Furthermore, data structures can be made transparent to `@op`s, so that an `@op` can be called on a list of outputs of other `@op`s, or on an element of the output of another `@op`. This creates an expressive "web" of `@op` calls over time. 2. a data structure, `ComputationFrame`, can automatically organize any such web of `@op` calls into a high-level view, by grouping calls with a similar role into "operations", and their inputs/outputs into "variables". It can detect "imperative" patterns - like feedback loops, branching/merging, and grouping multiple results in a single object - and surface them in the graph. `ComputationFrame`s are a "synthesis" of computation graphs and relational databases, and can be automatically "exported" as dataframes, where columns are variables and operations in the graph, and rows contain values and calls for (possibly partial) executions of the graph. The upshot is that you can query the relationships between any variables in a project in one line, even in the presence of very heterogeneous patterns in the graph. I'm very excited about this project - which is still in an alpha version being actively developed - and especially about the `ComputationFrame` data structure. I'd love to hear the feedback of the HN community. Colab quickstart: https://ift.tt/b7fUM0G...

Show HN: Dut, a fast Linux disk usage calculator https://ift.tt/tR4HhQV

Show HN: Dut, a fast Linux disk usage calculator "dut" is a disk usage calculator that I wrote a couple months ago in C. It is multi-threaded, making it one of the fastest such programs. It beats normal "du" in all cases, and beats all other similar programs when Linux's caches are warm (so, not on the first run). I wrote "dut" as a challenge to beat similar programs that I used a lot, namely pdu[1] and dust[2]. "dut" displays a tree of the biggest things under your current directory, and it also shows the size of hard-links under each directory as well. The hard-link tallying was inspired by ncdu[3], but I don't like how unintuitive the readout is. Anyone have ideas for a better format? There's installation instructions in the README. dut is a single source file, so you only need to download it and copy-paste the compiler command, and then copy somewhere on your path like /usr/local/bin. I went through a few different approaches writing it, and you can see most of them in the git history. At the core of the program is a datastructure that holds the directories that still need to be traversed, and binary heaps to hold statted files and directories. I had started off using C++ std::queues with mutexes, but the performance was awful, so I took it as a learning opportunity and wrote all the datastructures from scratch. That was the hardest part of the program to get right. These are the other techniques I used to improve performance: * Using fstatat(2) with the parent directory's fd instead of lstat(2) with an absolute path. (10-15% performance increase) * Using statx(2) instead of fstatat. (perf showed fstatat running statx code in the kernel). (10% performance increase) * Using getdents(2) to get directory contents instead of opendir/readdir/closedir. (also around 10%) * Limiting inter-thread communication. I originally had fs-traversal results accumulated in a shared binary heap, but giving each thread a binary-heap and then merging them all at the end was faster. I couldn't find any information online about fstatat and statx being significantly faster than plain old stat, so maybe this info will help someone in the future.

It's a cool CLI tool that we created as part of an internal team hackathon. Earlier, deploying a model to Triton was very tough. You had to navigate through the documentation for the Python backend, figure out how to get your inputs and outputs right, write a bunch of glue code, create a config.pbtxt file with all the correct parameters, and then package everything up. It could easily take a couple of hours. But with Triton Co-Pilot, all that hassle is gone. Now, you just write your model logic, run a command, and Triton Co-Pilot does the rest. It automatically generates everything you need, uses AI models to configure inputs and outputs, and handles all the tedious parts. You get your Docker container ready to go in seconds. Check out our GitHub repository and see how much easier deploying to Triton can be!

Show HN: I coded my own JSON translation tool to easily localize my side project https://ift.tt/x75QWPc

Show HN: I coded my own JSON translation tool to easily localize my side project Hi HN, I’m Joan, the developer of Quicklang. I made this app to easily translate and keep in sync all my localization JSON files for my side projects. While searching online for a similar tool, I only found enterprise solutions that do not allow direct editing of JSON files. I used to use ChatGPT to translate the JSON translation file changes before coding Quicklang. However, I realized that ChatGPT only allows you to input short content for translation into another language (even if you provide a .json file), and each time I had to request translations for one language at a time. So, I decided to build an app that only sends the changes I’ve made to the OpenAI API and easily translates them into all the target languages for my side projects. Technical details: I used Next.js to build the front end and backend, and I use a custom VPS (EC2 instance) on AWS to handle the translation process. This is because the translation can take several minutes, and Vercel Functions time out after 10 seconds by default (up to 60 seconds on the Hobby plan). Finally, I save the translation files in an S3 bucket. What’s next? I want to add cool features like change history, the capability to add context to the OpenAI API to make translations as accurate as possible, and maybe allow developers to interact with the API in order to use the tool. Let me know your thoughts and feedback. It’s been a blast working on this so far, and I think it’s just neat :) https://ift.tt/4jieNg6 July 8, 2024 at 11:16PM

Show HN: Foorr – A minimal to-do app with social accountability https://ift.tt/hQBjzOf

Show HN: Foorr – A minimal to-do app with social accountability I've created Foorr, a minimal to-do list app that focuses on short-term getting-things-done and the option to do this with friends by holding each other accountable and helping each other grow together. Main goal is to fuel your progress whatever needs to be done and hold yourself accountable for your own progress (with some external motivation). Here's what it does: - Create tasks for today and tomorrow only (real hyperfocus on short term GTD). - Invite friends to cheer each other moving forward. - Building up a daily streak as you finish all tasks daily. All tasks completed before midnight which were planned for that day, earns you a level up. Rewarding that sense of completion. Why I built it: I used physical post-it notes and was a bit done with it. I really wanted something minimal focusing only on my to-do's for today and tomorrow. No bloated features, nothing to fancy/polished, just something no-nonsense I wanted to use myself. It might be useful for others who struggle with procrastination and keeping op progress getting things actually done. Feedback is definitely welcome and nice to hear if this resonates with anyone else. https://foorr.com/ July 5, 2024 at 01:44AM

Show HN: I made a search engine for Hacker News https://ift.tt/Z6RfyHP

Show HN: I made a search engine for Hacker News I love HN but always felt the search with algolia is okay but does have some limitations. Since I work at Vectara I decided to try and create a better search for HN. It's based on data from roughly the last 6 months of HN stories and comments. Would love to hear feedback and how useful this is relative to the existing search. https://ift.tt/hrV6sfm July 3, 2024 at 01:41AM

Show HN: Perlin noise Wang tile generator https://ift.tt/lHV4qfh

Show HN: Perlin noise Wang tile generator This is a little script I wrote a while ago to help generate sprites for a game I was working on. You can use it to build a seemingly-infinite aperiodic noise texture that is actually composed of a relatively small number of tiles. For example, imagine a large grassy field or body of water in a 2D pixel art game, but without the obvious repeated patterns that arise from simple tiling. The use case is pretty niche (for example, in many cases you could just evaluate the perlin noise function directly in a shader) but I thought it was a cool idea regardless. https://ift.tt/iJF9ZfE June 27, 2024 at 11:06PM

Show HN: I built sales API, Stripe Atlas closed me https://ift.tt/cSvPnL7

Show HN: I built sales API, Stripe Atlas closed me My Co-founder and I have spent the last three months developing customsalesapi.com, a platform designed to automate sales and lead generation processes. Essentially, we streamline everything you'd typically do with Apollo by describing your company to our AI. If you're interested, I'd be thrilled to have you as one of our early clients. Please let me know if you'd like more information. Few days ago, we used Stripe Atlas to create our company, and right after company is created, stripe closed our account (account id is acct_1PMyxBIbdJ0fozrG). I went to asking help from many groups but I saw this exact same thing is happening everywhere July 2, 2024 at 01:00AM

Show HN: Improve LLM Performance by Maximizing Iteration Speed https://ift.tt/lZDmE14

Show HN: Improve LLM Performance by Maximizing Iteration Speed LLM Application development is extremely iterative, more so than any other types of development. This is because in addition to all the activities involved in regular application development, we also need to make the LLM Application accurate and reduce hallucination. To improve performance, we need to trial and error various combinations of LLM models, prompt templates (e.g., few-shot, chain-of-thought), prompt context with different RAG architecture, try different agent architecture, and more. There are thousands of permutations to try. We need to be able to easily experiment with these different permutations, measure performance in an objective way, and compare performance across each other to find the best possible combination. --- I have been working in AI since 2021 - first at FAANG with ML, then with LLM in start-ups since early 2023. I have had the chance to talk with many companies working with AI. The biggest mistake I see is a lack of standard process that allows them to rapidly iterate towards their performance goal. Using my learnings, I’m working on an OSS framework that structures your LLM Application Development for Rapid Iteration so you can reach your performance targets much faster. - If you are interested, you can learn more about it at: https://palico.ai/ - It's also Open Source and you can get setup with a single command.

Show HN: I've built a child monitoring app with mitmproxy and WireGuard https://ift.tt/G5WoCja

Show HN: I've built a child monitoring app with mitmproxy and WireGuard Hi! I've been working on a child monitoring service and I'd really appreciate your input on it. The structure of the service is pretty technically interesting. It sets up a wireguard VPN on the child's Windows account, and then routes the traffic to our server. From there, we use mitmproxy to break open the TLS, inspect the packets, and then re-encrypt them. Currently all images are passed through an ImageNetV2 model, and for sites like reddit or google, individual links/communities are analyzed and we remove the content if it violates the filters without impacting the overall browsing experience. Coming soon(ish) will be a 8B uncensored llama3 model, which will allow parents to create custom filters for filtering content. I've always felt like child monitoring systems are missing the bigger picture when it comes to content filtering. I certainly remember being a little kid (9-ish) and coming across adult content I shouldn't have been seeing, but I also recall encountering subreddits and other online groups that laid the groundwork for my personality, without my parent ever knowing what was happening. The fact that as a child, I declared I no longer believed in God before I stopped believing in Santa was not the result of being some super genius, but because I was regurgitating what I read on r/atheism as gospel. Parents need more control over what their kids see, and as the internet develops more mature communities child filters need to keep up. It is not enough to simply hope your kid turns out normal, because there are companies actively working against you. The service is $20 a month, although it's 50% off for the first two months while we're in early access. We also only do Windows at the moment, although I'd like to expand (especially to linux) later this year. Let me know what you think! https://ift.tt/6C18X5m June 30, 2024 at 10:44PM
