7. Show HN: Engineering Metrics Powered by AI
Author: ymatagne
Description: Show HN: Wellcode CLI - Open-source engineering metrics powered by AI
I built Wellcode CLI after getting frustrated with expensive engineering metrics tools that cost thousands per month but weren't actually helpful as a new engineering manager. The existing tools gave me lots of fancy graphs, but didn't help answer basic questions like "is my team stuck on anything?" or "who might need more support?"
The tool does three main things:
- Aggregates metrics from GitHub (PR velocity, code review times, etc), Linear (issue progress, cycle time), and Split.io (feature flag adoption)
- Provides a natural language interface so you can ask questions like "how was the frontend team performing last week?" or "show me who needs code review help"
- Uses Claude (optional integration) to analyze trends and suggest actionable improvements for new managers
What makes this different:
- Completely free and open source - no more paying thousands for metrics you don't need
- Works entirely from your terminal - no web dashboards or account creation needed
- Natural language interface that focuses on actionable insights for managers
- Integrates metrics across tools rather than looking at each in isolation
- Local-first - all data processing happens on your machine
You can try it out in 2 minutes.
The minimum requirement is just GitHub access - the Linear, Split.io and Anthropic integrations are optional.
Source code: https://github.com/wellcode-ai/wellcode-cli
Happy to answer any questions! While I've built several internal metrics tools before, this is my first open source project, so feedback is very welcome.

11. Show HN: The Canada census data in a SQLite file; advice appreciated
URL: https://github.com/rendello/canada-census-2021-sqlite/releases/tag/1.0.0-alpha
Author: Rendello
Description: This is niche, I'll admit.
I needed to look through the latest census data, but it was exported as multiple multi-gigabyte bespoke latin1-encoded CSV files. Pandas, Polars, and SQLite's CSV import tool weren't much help, so I shelved the project until recently, when I started taking a SQLite course online.
I picked it up again, normalized the data, and now there's a database that can be queried through a SQL view that matches the headings in the original CSVs. I'm proud of the script I created to export the data, as well as automatically compress the artifact, make the diagrams and checksums, etc.
This is my first time building up a big database, does my schema seem sane? I've been considering switching the counts from REALs to TEXT, since then SQLite's decimal extension can do exact calculations, but considering there's only one or two places after the decimal points in the data, I'm not sure if it's worth it space-wise.

14. Show HN: Chatten – Interact with SaaS products through chat
URL: https://www.youtube.com/watch?v=HJOG0_IUVeU
Author: muyabb
Description: Hi HN!
---
First, the story;
In my previous startup, I was the head of product of a grocery delivery app similar to Instacart. Our main competition was people sending orders to the stores through WhatsApp.
Ordering groceries on WhatsApp is very difficult, especially large (10+ item) ones. Our app was much more convenient because the whole UI was curated for grocery ordering.
However, when it came to small orders of obvious items, e.g. an order consisting of 1 kg tomato, 3 eggs, and 2 breads, consumers preferred WhatsApp over our app!
When we asked why, they said "For a simple order using WhatsApp, all I have to do is send a voice message or a short text to the store. But on your app, I have to open the store, open categories, find each item, add them in the right quantity to cart, open cart, confirm location and press order. A lot of clicking and hassle!"
They were right. Our app contained a listing of 1000s of items all arranged in categories with advanced search. What made it great for browsing the store items and placing large orders also made it inconvenient for small orders of obvious items, which were actually more common.
I couldn't merge the convenience of unstructured WhatsApp-style ordering with the structured experience of our app. This problem is inherent to the GUI and every SaaS must have it. It wasn't fixable, or so I thought.
Enter Chatten...
---
Chatten fixes exactly that problem. Chatten makes it possible for to users read and mutate data, and navigate through a SaaS through chat commands.
It maps the user command to a series of API requests and frontend events that are performed on behalf of the user. The user does not need to do multiple high-precision and attention-demanding clicks on the UI.
Watch the demo to see a PoC in action.
Chatten is currently very early stage. I appreciate all kinds of feedback. If want to be an early adopter, or wanna connect, reach out on my LinkedIn https://www.linkedin.com/in/mohammedshahoe/

URL: https://www.limejourney.com
Author: flyingsky
Description: Hello HN - I’m Tobi and I am building LimeJourney. LimeJourney is an open source customer engagement platform, a Customer.io /braze etc alternative.
- For the past few weeks I have been hacking on LimeJourney during my free time and I’m inviting you to check it out and give your feedback. You can try out the demo with email and password demo@limejourney.com/demo@limejourney.com
- My Grand thesis for building LimeJourney is that the channels through which we currently receive notifications will not be changing anytime soon but with the increase in data - now more than ever - businesses that will catch the attention of customers are the ones who in some shape or form are intelligently sending notifications(possibly with AI).
- LimeJourney in its current form is very far off from what I hope for it to be but still solves a couple of issues I experienced when working on another project. LimeJourney is relatively cheap($50) - single base plan compared to the other big guys in the market(>$100). It is also open source and I’lld love to see folks who are able to, adopt and self host limeJourney. LimeJourney aims to play real nice with whatever you current email sending stack is and we already have integrations with Resend, AWS and are building more.
The codebase is on Github => https://github.com/LimeJourney/limeJourney
Thank you for checking this out. You can reach me at tobi@limejourney.com

19. Show HN: A novel markup language for lists – Describe
URL: https://github.com/viktorchernev/DescribeCompiler
Author: demon_of_reason
Description: Describe Markup Language is a markup language for writing lists that I have developed over the past 2 years. It is based on ANTLR 4.13 and the compiler is coded in C#, and can be consumed in .net projects, ran from the Windows command line, or hosted as a microservice on the Amazon Cloud (AWS). Or more officialy:
Describe is a markup language designed to write and maintain complex data lists that are compiled on demand to various formats, such as html, xml, sql and json. It is simple to use, intuitive and easy to master. Describe is readily extendible - implementing support for new target languages or customizing the transpilation process is straightforward, making it adaptable to a wide range of projects.
I need this markup as a part of another project, but it is cool on its own, and since v1.0-beta of the compiler rolled out, I've figured - "why not share it around with people?"

21. Show HN: After 3 months of coding, I built a feedback tool for indie makers
URL: https://feedhunt.app
Author: Yeeze
Description: Hey HN,
After 3 months of coding and countless iterations, I’ve launched Feedhunt, a lightweight feedback tool designed for indie makers and small teams.
The idea came from my own frustration with managing user feedback while building projects. Existing tools felt too bloated, complicated, or expensive ($359/month isn’t indie-friendly). So, I decided to scratch my own itch and create something focused and affordable.
With Feedhunt, you can:
- Collect feedback from your users
- Let them vote on what matters most
- Organize feedback with tags and status filters to keep your roadmap clear
I built this using nextjs and PostgreSQL. It’s intentionally simple—just enough to solve the problem without unnecessary fluff.
It’s live now, and I’d love for you to try it out: https://feedhunt.app/
Would appreciate any feedback, whether it’s about the product, the approach, or the tech. Thanks for taking a look!

22. Show HN: Analyze utility data and get alerts
URL: https://youtilitics.com/?hn
Author: ClaudyFocan
Description: We started this product to analyze water usage which was too high for a house. We ended up improving it to support gas and electricity and provide insights and usage information.
It can also detect abnormal increase weak over weak and send an email, e.g. for a water leak or over use.
It can show electricity usage with separation from EV, AC and everything else. It's not perfect but it works.
Account required (you also need to download your utility data) but it is free for 2 weeks.
To get data, you need a Green Button compatible utility, or one compatible with our Sync Companion app (HTTP client to log in to your utility and download a CSV); feel free to reach out if you want to add your utility.
Thanks HN!

23. Show HN: Minimalboard – A intuitive and fast way to organize work
URL: https://minimalboard.com/
Author: IndieCoder
Description: Hi HN!
Organizing my work has always been frustrating because no tool seemed to fit my workflow. Every app I tried came with endless menus, complicated settings, and more clicking than actually working. If you've ever wrestled with Jira, you know the drill — its great for tracking an army of developers, but a tad overkill for my personal tasks.
That's why I built Minimalboard. It combines the simplicity of a good old notepad with the visual organization of a Kanban board. Its sole focus is speed and intuitiveness. Just click to start editing, drag to rearrange, and everything saves automatically. It's a quick, clean workspace to jot down ideas, organize tasks, or capture information on the fly.
I've been using Minimalboard privately for two years, and now I'm releasing it to see if I'm the only one with this peculiar obsession for simplicity or if others are equally struggling. Give it a spin and let me know what features you'd find useful. I'm curious to see how much functionality I can stuff in before it starts looking like, well, the tools I was trying to avoid!

27. Show HN: A WebSocket API for real-time transcription and translation
URL: https://docs.speakprecisely.com/docs/quickstart
Author: mimponenti
Description: I built a websocket API that does real-time speech-recognition, and also translates at the same time.
The result is a real-time transcript in one or many languages, while maintaining <500ms in latency.
Typically you'd have to setup a back-end instance to relay audio to-and-from the front-end and a transcription API. You'd also have to setup API calls with multiple providers, parse transcripts, optimize configurations, create backup instances, add instances in different geo-locations, etc...
The goal is to abstract all of this, so you can connect directly from the front-end by using a public key, and optionally OAuth tokens from supported identity providers.
The link on this post will take you to docs for connection via Websocket or Javascript SDK

29. Show HN: I Used Llama-70B Logprobs for Better, Cheaper and Faster Chunking
URL: https://github.com/ZeroEntropy-AI/llama-chunk
Author: ghita_
Description: The LlamaChunk algorithm is simple: We pick a special token that we know is not in the corpus, e.g. "段".
We pick the character "段" because
- tiktoken always encodes it to exactly one token,
- it is not in the corpus, and
- it means "section" in Chinese.
Then, we ask Llama to repeat the User's message with the "段" token sprinkled throughout. And just like that, it's perfect out of the box! It correctly used the "段" character to mark the end of every section.
BUT if you've ever worked with LLM's, you know that input tokens are processed almost instantly, and output tokens take an eternity to generate. A naïve method is to simply wait for the LLM to repeat the entire python code, inserting "段" throughout.
However, by inferencing llama locally, we have a vastly more efficient way of doing this! We can simply pass in the entire paragraph, and check the logprobs to see the probability that Llama wanted to output a "段" token at that location!
Done! The high logprob values, clearly indicate the locations that we should chunk! And, this is only possible because we have direct low-level access to Llama 3.1 70B.
Of course, there is a caveat. Because there are no output tokens, Llama can no longer see its own line breaks. Thus, as the text gets longer, it loses the willpower to continue to want to output "段"
But, we can simply normalize by this decaying curve in order to to fix this. And now, we're ready to split any type of document, without having to resort to regex or manually created rules.
Processing 450,000 characters took about 15 minutes on an A100. However, ~80% of that time was saving and loading the KVCache (Which can be done instantly if written in C++, rather than Python). So, we can expect that it would take 3 minutes per 450,000 characters if done optimally. Or, 7 MTokens per hour.
In terms of accuracy, LlamaChunk has higher recall AND precision, than a naïve chunking method and than semantic chunking (Which uses embeddings to detect sentence split boundaries, and still requires a good regex-based sentence splitter).
---
One thing you might wonder: What if the ideal chunk split is not along a token boundary?
Well for one thing, this is rare, as tokenizers intentionally split along meaningful boundaries. However, if the best split really is after the "f" in "fun", then you calculate
``` lp = logprob(prefix="Fine Tuning is", next_token=" f") if lp > -7: lp *= logprob(prefix="Fine Tuning is f", next_token="段")

**Description**: Hi everyone! My name is Kyle, and I built Textyle originally as a way of adding my own business and engineering context on top of the online documentation that I used every day. I was using the Amazon CDK documentation often and thought it would be useful to mark it up to avoid my and my team's repeated questions by opening up question threads directly on the source of truth.<p>Annotations are made on a layer on top of the web and are anchored there by matching XPath and text. They are organized into groups similar to Slack workspaces and Discord servers and are also separated into channels.<p>After having built the product, candidly, I'm not sure what the best use case for a tool like this is, but I thought I would show it to you!

**Author**: onnies
**Description**: Hi HN, was thinking about the Agent economy over thanksgiving, and decided to hack together a prototype of what that could look like.<p>The key problem arises when giving LLMs your credit card information, essentially PII that could be leaked, used as training data, or manipulated. The next layer up comes from the Agent orchestration (CrewAI, etc) that needs to be secure itself, but this agent will likely be running on some server opposed to locally. Finally, to hold customer credit card information, the developer will have to be PCI compliant. If they use Stripe, they have to fund the account and manage the transactions, fraud, compliance & account funding.<p>In this demo, what I did was use CrewAI to ask to find me an 8.5x11" notebook with a hard cover & elastic strap, multiple agents separated did research, decision making and finally for purchase I used Browserbase to have an agent autonomously make decisions about the checkout.<p>During the checkout process it took the DOM, extracted the key data & sent me a confirmation email, which I used as the callback for the virtual credit card creation process. The credit limit is equal to the total purchase amount and only has a lifetime of one hour.<p>Would love to hear your thoughts on what the future of the AI economy looks like!

**Author**: ebetica0
**Description**: Hey HN! We're releasing ESM C, a series of protein language models that set a new state of the art. By training on metagenomics and fine-tuning on UniRef, we're able to match ESM2 650M with ESM C 300M, and ESM C 6B has incredible unsupervised contact precision performance. These models are meant to be used as base models and representation learning models for protein sequences, and we'll release a preprint describing exact details soon.

Mostly to take some inspiration or analyze competitors to my other products.<p>2 weeks ago, I though it would be fun to learn more about NuxtJs (I’m a software engineer working with Vue). So I thought building a directory website out of this collection was pretty good idea.<p>After 2 weeks of building, YouMightNotNeed was born. It's a community driven list of alternatives to popular software and applications.<p>Enjoy and thank you for your support!<p>PS: I know there are already websites that have the same purpose but it really came from my will to learn new stuff.

## 46. Show HN: Vekos – a Rust OS with Built-In Cryptographic Verification
**URL**: [https://github.com/JGiraldo29/vekos](https://github.com/JGiraldo29/vekos)
**Author**: jgiraldo29
**Description**: VEKOS(Verified Experimental Kernel OS) is a Rust-based experimental kernel that focuses on runtime verification and security. Every filesystem operation and memory allocation generates cryptographic proofs that can be verified in real-time, ensuring system integrity. Think of it like a blockchain for OS operations rather than just storage verification.<p>Key features:
- Merkle tree-backed filesystem with operation verification
- Memory manager with CoW and proof generation
- Buddy allocator with zone-based memory management
- Shell with VT100 support
- Verified boot sequence with stage attestation<p>The kernel is still in alpha, but it demonstrates a novel approach to OS security by making verification a first-class citizen. All critical operations (memory allocations, filesystem writes, process creation) generate proofs that are stored in an append-only chain, similar to a blockchain but for system operations.<p>GitHub: <a href="https://github.com/JGiraldo29/vekos">https://github.com/JGiraldo29/vekos</a><p>I would be excited to get feedback on this project, especially on the verification approach and potential use cases. If you have any question the innerworkings of the development, just ask and I will gladly answer all questions. The code is under the Apache 2.0 license and welcomes contributors.

## 48. Show HN: Build Live AI and RAG Pipelines in Minutes with YAML Templates
**URL**: [https://pathway.com/developers/templates/](https://pathway.com/developers/templates/)
**Author**: janchorowski
**Description**: Hello everyone!<p>I am Jan, CTO and one of the creators of Pathway, the real-time data processing framework. I’m excited to share Pathway’s ready-to-use AI Pipelines, configurable with just YAML! These frameworks offer out-of-the-box solutions for AI search, RAG, and more—optimized for real-time indexing and in-memory processing.<p>What makes it simple? YAML templates!
The pipeline templates are fully customizable using YAMLs to fit your needs, from changing the data sources to the choice of the LLM model, all without touching Pathway’s Python code.
Thanks to the Pathway data processing engine, these pipelines are optimized for real-time, updating the pipeline by ingesting the data as it arrives.<p>Why it matters:
* YAML templates: that’s it, no Python code required.
* Full customization: Configure everything, from LLM models and indexes to tokenizers and retrieval strategies.
* Real-time data sync: Connect to data sources like Google Drive, SharePoint, and more, with pipelines automatically updating to reflect all additions, deletions, and changes in real-time.
* Powerful search capabilities: Internal in-memory indexing supports vector, hybrid, and full-text search. The indexing is automatically maintained as data sources update in real-time.
* Deploy in minutes: Quickly deploy on-premises or on cloud platforms like AWS, GCP, or Azure.
* It's open: don't hesitate to contribute!<p>Templates: <a href="https://pathway.com/developers/templates" rel="nofollow">https://pathway.com/developers/templates</a>

However, most of my posts didn't gain much traction.<p>After analyzing hundreds of viral posts, I found that successful creators often use specific patterns and structures that make their content more engaging.<p>So, I built an AI tool <a href="https://writastic.com" rel="nofollow">https://writastic.com</a> to help identify and apply these patterns. It has two key features:<p>- Analyzer: Extract patterns from successful creators
- Rewriter: Apply these patterns to your content while preserving your core messages<p>Don’t get me wrong, it’s not another AI spam generator. It works for reshaping your existing content.<p>Feel free to share your thoughts!

## 51. Show HN: Built a City Explorer Because My Wife and I Got Tired of Switching Apps
**URL**: [https://travo.me/](https://travo.me/)
**Author**: Bnicovski
**Description**: Hey HN!<p>You know that feeling when you're exploring a new city, and you stop in front of this stunning building or quirky statue, but have no clue about its significance? That was me and my wife last year, constantly switching between apps and guidebooks instead of actually enjoying our travels together.<p>After one too many times of saying "I wish we knew the story behind that," I decided to build Travo. It's a city guide that lives in your pocket, born from real frustration and countless hours of getting lost in beautiful places (sometimes intentionally, often not).<p>I've spent the past year working solo on this, turning those travel pain points into something I hope makes exploring cities more enjoyable and less about staring at multiple screens. The goal? Let you wander freely while still knowing the rich stories behind everything you're seeing.
Travo transforms your smartphone into an interactive city guide that combines maps, audio narration, and local insights. It helps you discover hidden gems and cultural landmarks at your own pace. Here's what you get:<p>• Interactive city exploration with rich historical context
• Self-guided tours with audio storytelling
• 7-day customizable itinerary planning
• Easy navigation with Google/Apple Maps integration
• Stories available in 13 languages<p>I decided to keep it simple: start with 8 free cities and unlock more with one-time purchases. No subscriptions, no ads - just pure exploration. Special for HN readers: use code HN2024 to unlock one city of your choice!<p>The challenging part? As a solo developer, I've had my share of late-night debugging sessions and moments questioning my sanity.
I'd love to hear from fellow developers about managing projects solo, and from travelers about what would make this more useful for you. Particularly interested in your experiences with the interactive map and content curation.
Try it out and let me know what you think! I'm here to answer questions and learn from your insights.

## 52. Show HN: Reverse Engineering React.js Internals
**URL**: [#](#)
**Author**: aidenyb
**Description**: I’ve been exploring React.js internals and found them hard to access, so I reverse-engineered how React DevTools hooks into React and built a package: <a href="https://github.com/aidenybai/bippy">https://github.com/aidenybai/bippy</a><p>For a bit of context: React represents UI as a tree of "fibers," which hold data like props, state, and context. React updates UI in two phases: render (building the fiber tree) and reconciliation (scheduling & diffing fibers to update the DOM).<p>My tool works by simulating __REACT_DEVTOOLS_GLOBAL_HOOK__ to expose React internals without using DevTools:<p><pre><code> import { instrument, traverseFiberRoot} from 'bippy';
instrument({
onCommitFiberRoot: traverseFiberRoot({
onRender(fiber) {
console.log(fiber);
},
}),
});
</code></pre>
I’ve found it pretty useful for detecting re-renders (I made a separate tool to highlight renders on the page <a href="https://github.com/aidenybai/react-scan">https://github.com/aidenybai/react-scan</a>), but there are plenty other use cases for toy projects or learning how React works.<p>Happy hacking!

**Description**: Hey HN,<p>I am a student shipping apps in my free time. This is my 4th for the year!<p>Non-fic books and podcasts have been part of my life for years now but I always struggled with remembering what I’ve read or listened to. I wanted it to stick even after years.<p>My notes list grew large but I never really revisited them. That’s why I created GinkgoNotes.<p>You can enter notes you want to recall and leave it to the app to create a personalised (based on spaced repetition) email schedule. That means you’ll get your notes emailed to you a couple of times exactly when you should read them again (based on Ebbinghaus's Forgetting Curve) so it’s certain that you’ll remember them.<p>I hope this will be helpful as it was for me. Would love some feedback!<p>Iskren

## 56. Show HN: Latudio – a language acquisition app with a listening-oriented approach
**URL**: [https://www.latudio.com](https://www.latudio.com)
**Author**: vitro
**Description**: Hi HN,<p>One day after our morning meditation my friend Mark - an American living in Prague - said to me - what if we built a language app? I just replied “Let’s do it”. Little I knew this moment will change the course of my life for years to come.<p>Today, I’d like to present to you Latudio: <a href="https://www.latudio.com" rel="nofollow">https://www.latudio.com</a> - a language acquisition app that helps you learn languages naturally through listening. Currently, we support French, Czech, Latin American Spanish, and Italian (all paired with English), with Brazilian Portuguese coming soon (available in preview at the moment).<p>The problem with most language apps is they focus heavily on reading and writing from day one. With our app we took a slightly different approach to acquiring a language, a “hack” in a way. All exercises are for listening, there is no text to read right from the start. But, if you’re ever lost and don’t understand what’s being said, you can pause the audio anytime to see the sentence. Any word in the sentence can be tapped on and you will see its contextual translation, which may be sometimes different to a dictionary translation of the word. And, each word tapped gets saved in your dictionary for later reviewing. In a dictionary, you can list all sentences containing the word in all various forms it can take - a great help if you want to explore words and get the feeling of the language.<p>The app contains several types of exercises:<p>Sentences
- listen, reorder words, write the sentence, then record it.<p>Stories
- listen to the story, then answer questions to be sure that you understood well. Also you can match sentences to its correct photo.<p>Conversations
- scripted conversations where you take part as one speaker and try to record your voice to match the original recording.<p>Booster
- like Sentences exercise, but you can select your own set of sentences.<p>You can also set goals and view statistics about your progress.<p>None of this would be possible without the great help from hundreds of our contributors [1], who translated, mapped and recorded content. All the content you find in the app was reviewed multiple times by several people and recordings are made by native speakers.<p>No story in the app was created by a LLM, all exercises are created and curated by us.<p>Privacy-wise, we collect as little information about our users as possible. For example, we didn’t include Facebook SDK even if it would be easier for us to implement Facebook login that way. Deleting your account really makes our app forget everything about you.<p>Some technical details - the app is written in React Native, API is written in Java (Javalin [2]). Our content development platform uses Apache Wicket [3]. BunnyCDN is used for content delivery. "Use boring technology", they say, so we did.<p>We rent a bare metal server from Hetzner and use Proxmox for VMs management. Our setup is fairly simple but flexible enough for us to grow if we need to. My approach always was, that if we’d need to figure out how to scale beyond VMs and multiple servers, we’d also have finances to hire a DevOps person for that. It will be a nice problem to have.<p>Latudio is completely bootstrapped, without any VC funding, allowing us to focus on our vision and users' needs.<p>Hope you’ll like the app. If you’d like to know more about our journey, I’ll be happy to answer your questions in the comments.<p>P.S.: we offer the app for free to nonprofits who take care of people that are at a disadvantage. We can also create custom content tailored to their specific needs - like training exercises for hospital workers or language exam prep for refugees. If you know someone who could benefit from this, we'll be happy to know. E-mail is in my profile.<p>[1] <a href="https://www.latudio.com/about-us/contributors" rel="nofollow">https://www.latudio.com/about-us/contributors</a><p>[2] <a href="https://javalin.io/" rel="nofollow">https://javalin.io/</a><p>[3] <a href="https://wicket.apache.org/" rel="nofollow">https://wicket.apache.org/</a>

My inner nerd was like, "There has to be a better way."<p>I've just launched a new open-source project called Engity's Bifröst, and it's ready for you to try out. It's licensed under the Apache 2 License and offers the following features:
1.) It also supports OpenID Connect (SSO) and works with the normal SSH client on any operating system, in addition to the usual mechanisms like SSH keys and passwords.
2.) You can not only connect to the console of the host where Bifröst is running, but you can also start a separate Docker container or Kubernetes pod for each session (with its own images, etc.).
3.) Bifröst also supports what are called flows. These are comparable to virtual hosts as we know them from HTTP.<p>Unfortunately, I'm now stuck adding more and more features. I'd love to hear your thoughts and I'm excited to have you on this journey with me.

**Author**: seanmorley15
**Description**: AdventureLog started as my first attempt at full-stack development. From React and national parks datasets to learning Svelte and Django, it’s been a journey of discovery. I’ve learned more from building this project than any tutorial. If you’re an aspiring developer, I highly recommend picking a project and diving in. It may seem overwhelming at first but you will soon learn how to use resources and documentation to make something you could never imagine was possible. Tutorials are great, but nothing compares to the challenge of creating something from scratch.<p>INTRO
AdventureLog is the ultimate travel companion for the modern-day explorer. With AdventureLog, you can log your travels, plan trips collaboratively, and share experiences — all in one app.<p>FEATURES
- Track Your Adventures : Capture every trip and visualize your travels on an interactive world map.
- Plan Your Next Trip : Build and customize itineraries effortlessly with an intuitive planner.
- Share Your Experiences : Collaborate with friends, share photos, and relive your favorite memories together.<p>OPEN SOURCE AND SELF HOSTED
- GPL-3.0 License
- Self-hostable with docker and other common methods<p>WHY ADVENTURELOG?
AdventureLog was created to solve a problem: the lack of a modern, open-source, user-friendly travel companion. Many existing travel apps are either too complex, too expensive, or too closed-off to be useful for the average traveler. AdventureLog aims to be the opposite: simple, beautiful, and open to everyone.<p>----

**Author**: chernishev
**Description**: We are excited to announce a new release of Desbordante — an open-source, high-performance data profiler that discovers and validates complex patterns in data using a large set of advanced algorithms.<p>Unlike existing data profilers, Desbordante focuses on discovering complex patterns in data, which are notoriously hard to extract. Since its launch in 2019, it has become the fastest open-source tool for these tasks, while also offering many patterns which have no alternative implementations. We already showcased it here back in April — see <a href="https://news.ycombinator.com/item?id=40063137">https://news.ycombinator.com/item?id=40063137</a>.<p>With this release, Desbordante now supports 24 types of patterns, 32 types of pattern-related tasks, and 34 algorithms for their discovery or validation. The key updates of this release are:<p>1) Discovery of many exciting patterns, with differential and matching dependencies being the most interesting (take a look at the new example scripts in our repo for a real-world demo)<p>2) Five new metrics used to define subtypes of approximate functional dependencies — they’re gaining popularity in the academic community for a wide selection of use-cases<p>3) Validation of denial constraints, which provide users with the freedom to check their own complex data constraints (expressed by a Boolean formula) over a table<p>4) Laid out the groundwork for dynamic algorithms — a novel type of pattern validation<p>- They track changes in the dataset to update their result on-the-fly rather than process the whole table again<p>- Implemented an example algorithm: dynamic functional dependency validator with a Python interface<p>5) Expanded to 33 examples across three categories:<p>- Basic — a clear demo of a singular pattern,<p>- Advanced — exploration of pattern variations and complexities,<p>- Expert — real-world solutions which use pattern discovery and validation<p>Of course, we have fixed several critical bugs, added new algorithms for existing patterns, and made some of the old ones run faster.<p>More about the release can be found here <a href="https://github.com/Desbordante/desbordante-core/releases/tag/v2.2.0">https://github.com/Desbordante/desbordante-core/releases/tag...</a> and more about the tool here <a href="https://github.com/Desbordante/desbordante-core">https://github.com/Desbordante/desbordante-core</a>.

Learn how to create dynamic agents that plan, execute, and adapt seamlessly, complete with code examples using LangGraph.<p>Chapter 10: Plan-and-Execute Agents<p>10.1 Introduction
The Plan-and-Execute architecture enhances reasoning tasks by splitting them into two core phases: Planning and Execution. This approach is derived from the Plan-and-Solve methodology, which contrasts with traditional single-step (ReAct) agents. The Plan-and-Solve architecture is particularly useful when dealing with complex multi-step reasoning tasks that require explicit planning for long-term goals.
In this chapter, we explore how Plan-and-Execute agents work by devising a multi-step plan and executing it in phases. The agent adapts as necessary, allowing for re-planning in case some steps fail or require more context.
10.2 Why Use Plan-and-Execute?
One of the key issues in multi-step reasoning tasks is that even sophisticated models like GPT-4 often struggle with explicit long-term planning. Plan-and-Execute solves this by:
● Breaking down complex tasks into smaller, manageable steps.
● Adapting dynamically based on intermediate results.
● Revisiting the plan when necessary to adjust or correct steps.
This architecture is superior to traditional ReAct (React-then-Act) models as it emphasizes forward-thinking (planning) before acting.
10.3 Plan-and-Execute Concepts
From the paper Plan-and-Solve Prompting: Improving Zero-Shot Chain-of-Thought Reasoning, the Plan-and-Solve approach addresses the limitations of Zero-shot-CoT (Chain-of-Thought), which typically fails due to:
1. Calculation Errors: Mistakes in intermediate calculations.
2. Missing-Step Errors: Skipping important intermediate steps.
3. Semantic Misunderstandings: Misinterpretation of the problem context.
To solve these issues, Plan-and-Solve introduces two key steps:
1. Planning: Devising a clear plan to divide the overall task into subtasks, ensuring no steps are skipped.
2. Execution: Executing each subtask and refining the plan if needed.<p>In the Plan-and-Solve architecture, the agent takes a multi-step approach:
● First, it plans out a sequence of steps.
● Then, it executes the steps one by one.
● If any part of the process fails or if more information is needed, it re-plans the sequence, ensuring robustness and flexibility.
