Show HN: The pure Python SaaS starter kit https://news.ycombinator.com/item?id=35764635
Show HN: The pure Python SaaS starter kit Hi HN, Recently, I’ve noticed there’s a decently high barrier to entry in developing competitive, full-stack SaaS applications. Beside the standard, boring features that take months to implement, you typically have to know several languages and frameworks, and be familiar with fancy frontend styling classes. I’m working hard right now to solve this problem by building PySaaS- The 100% pure Python SaaS starter kit. PySaaS is a boilerplate Python codebase that takes care of the fundamental components standard to all SaaS applications. The codebase uses the Pynecone web framework to compile your frontend into a NextJS app, so you never have to touch any HTML, CSS, or Javascript. Pynecone is easy to learn, yet fully flexible and powerful enough for advanced use cases. We implement out-of-the-box functionality for secure Firebase user authentication, Lemon Squeezy subscription management (MoR removes a major tax headache), Notion as a headless blog CMS, and more. Our mission is to help developers and founders save months of development time and focus on building unique features, which will in turn provide more opportunities to generate revenue and give value to customers. And easily do it in pure Python! Frontend. Backend. All in Python. To check out the live demo for free, click the link and then the “See Demo” button. Let me know what you think. https://pysaas.io April 30, 2023 at 10:22AM
Show HN: Eva AI-Relational Database System for Faster AI-Powered Applications https://news.ycombinator.com/item?id=35764355
Show HN: Eva AI-Relational Database System for Faster AI-Powered Applications Hi friends, We are building EVA, an AI-Relational database system with first-class support for deep learning models. Our goal with EVA is to create a platform that supports AI-powered multi-modal database applications operating on structured (tables, feature vectors, etc.) and unstructured data (videos, podcasts, pdf, etc.) with deep learning models. EVA comes with a wide range of models for analyzing unstructured data, including models for object detection, OCR, text summarization, audio speech recognition, and more. The key feature of EVA is its AI-centric query optimizer. This optimizer is designed to speed up AI-powered applications using a collection of optimizations inspired by relational database systems. Two of the most important optimizations are: + Caching: EVA automatically reuses previous query results (e.g., inference results), eliminating redundant computation and saving you money on inference. + Predicate Reordering: EVA optimizes the order in which query predicates are evaluated (e.g., running faster, more selective deep learning models first), leading to faster queries. Besides saving money spent on inference, EVA also makes it easier to write SQL queries to set up multi-modal AI pipelines. With EVA, you can quickly integrate your AI models into the database system and seamlessly query structured and unstructured data. We are constantly working on improving EVA and would love to hear your feedback! https://github.com/georgia-tech-db/eva April 30, 2023 at 09:52AM

Show HN: I made a tool to easily credit co-contributors in Git commits Hi Everyone! The motivation behind creating this tool is to provide an easy way to give credit to contributors in various situations: - In open-source projects, when a pull request (PR) is closed without merging but the idea or code is later implemented. - During pair programming sessions, where two or more developers work together on a single commit. Existing solutions were either too complicated or didn't work as expected, so Git Add Co-Author was developed as a simple, easy-to-use alternative. https://github.com/sansyrox/git-add-co-author April 28, 2023 at 02:47PM

Track crew removing old rail at the Van Ness crossover
The first Muni Metro Fix-It Week of 2023 was a resounding success in March, and it’s also the first Fix-It Week since the SFMTA launched the Central Subway in early January of this year. Here is a behind-the-scenes video recap. Fix-It Week is the SFMTA’s quarterly effort to optimize work time by closing Muni Metro early for critical maintenance. The SFMTA’s Maintenance of Way (MOW) teams did an excellent job maintaining the subway and preventing future breakdowns.
Fix-It Week helps the Muni Metro get a 20% improvement in speed and about a 20% improvement in reliability in the subway. It takes fewer minutes to take the N Judah from the Outer Sunset to Embarcadero now than it did in 2019.
From March 16 to March 22, 2023, the Muni Metro Subway between Embarcadero and West Portal closed at 9:30 p.m. to provide SFMTA maintenance crews an extended window to perform underground infrastructure improvement work that cannot be completed during the usual overnight windows. During the subway closure, buses provided substitute service for Muni Metro lines on the surface and connected all stops on Market Street.
Track crew powerwashing station walls
The goal of Fix-It Week is to make Muni metro subway operations more reliable, ensure safety, and improve the customer experience. Nine MOW teams, Track, Cable Car, Motive Power, Maintenance Engineering, Mechanical Systems, Overhead Lines, Underground, Paint Shop and Signal, were involved in the maintenance work.
Major maintenance work includes:
- Track replacement and reinstallation from the Ferry Portal to the Van Ness Crossover
- Mechanical systems cleaning, maintenance and installation
- Signal repairs and upgrades, including the demolition of old train control system racks, equipment and wiring
- Track fastener and subway lighting surveys, and drain cleaning around switches
- Overhead Line inspections and Overhead Section Break hardware adjustments
- Debris removal and traction power substation inspections
- Cable Car maintenance and repairs
Custodial staff cleaning Church Station
The SFMTA teams completed over 2,000 hours of maintenance and inspections over the seven night shutdown. They were able to perform 161 feeder operations, replace more than 125 bulbs for trackway lighting in multiple locations, renew 750 feet of Overhead Contact System contact wire, replace eight blue light phones and inspect approximately 8,000 track fastener plates from the Ferry Portal to Powell Station.
Track crew powerwashing and removing trash from trackway
A support team was also contributed to the success of Fix-It Week. These staffers helped coordinate maintenance work, upheld all safety standards and ensured that subway service resumed on time every day.
The SFMTA will continue to keep the Muni Metro system in a state of good repair. The next Fix-It Week is scheduled for July 2023, and we thank you for your patience and understanding while we do this vital work.

Show HN: Jarvis AI – Text, iMessage, and Email ChatGPT We're back with another ShowHN! When we launched, you could text Jarvis AI using regular SMS messages from your phone. Since launching 3 weeks ago[1], we've introduced two new channels for using ChatGPT. Now you can use ChatGPT over SMS text message, iMessage for Apple-enabled devices, and via Email. It is super interesting to forward an email to Jarvis AI and see its thoughts on your email thread. It can help you brainstorm or it can suggest a reply to previous emails. 10 messages free forever, more volume is free over iMessage and Email for a limited time (until the HN hug of death!). You don't have to sign up or anything to try it. Just send a text to: +1 (855) 676-1two89. Thanks for checking this out. Many exciting features are coming soon to make this more than just a different interface to ChatGPT. We want to make AI accessible to more people, over more channels, with more useful things for your day-to-day. For medical professionals, we added the /diagnose command. Ask Jarvis "/diagnose 32 year old harsh cough" for example. Soon, we are adding features like /invoice for generating invoices and /remember for notes and reminders.

Show HN: Karrio – Open-Source Multi-Carrier Shipping API https://news.ycombinator.com/item?id=35727026
Show HN: Karrio – Open-Source Multi-Carrier Shipping API Hey HN! Daniel and Delali here; we are working on Karrio, an open-source shipping infrastructure. Our focus is on making it easy to integrate shipping into platforms. With Karrio’s open-source and universal shipping API, you can set up connections to a worldwide network of shipping carriers for national, international and last-mile services but also build your own network of local carriers. You can seamlessly add built-in shipping functionalities to your platform, enabling users to fetch live rates, buy labels, track packages, and more. You can check out our Github repo here: https://github.com/karrioapi/karrio . For developers in the logistics space, carrier integration is often a painful experience. We believe that an open-source solution is a viable alternative to building a shipping system from scratch in-house or getting locked in with a Saas multi-carrier API. Karrio aims to put you in control of your shipping network with lower engineering costs. (see how to get started here: https://docs.karrio.io/quick-start ). So far, we’ve built a unified shipping API compatible with most major carriers, such as FedEx, UPS, DHL, USPS, Canada Post, and more. With the flexibility of open-source, Karrio has interoperability with other multi-carriers and 3PL (EasyPost, Freightcom, etc.). And we plan on building more integrations. Karrio is evolving with the help of our community of early adopters, and we want to keep that going. Checkout our README to get involved with the project, file issues and request or contribute carrier integrations We currently offer a managed cloud service in private beta, with a pay-as-you-go plan for platforms and custom prices for enterprise customers. Don’t hesitate to reach out if you have any questions. We would love to hear your feedback and how Karrio can help with your project. https://github.com/karrioapi/karrio April 27, 2023 at 05:29AM

Show HN: An interactive map showing live wind farm generation in Great Britain GB Renewables Map an energy experiment created entirely in my free time (day job is visualisation at Octopus Energy). It's an interactive map showing live generation for major wind farms in Great Britain, showing what each wind farm is generating both now and in the past, and where that generation is physically located. Animated weather data is from WeatherLayers and shows current and historic wind conditions on the map, providing context to wind generation around the country. History mode allows you to go back in time and see wind generation and weather conditions for a particular date and time. It's great for exploring days of record generation, such as the 21.6GW record on January 10th, 2023! Prediction mode lets you see what wind farms are estimated to be generating using current wind conditions and model based on historic generation and wind speeds. Is a wind farm generating as you expect, or is there something to look into? An experimental feature allows you to see what future wind farms could be generating today (or in the past!) if they were already built and operational. If you click the "sparkle" button on the map you'll get to see what the upcoming 3.6GW Dogger Bank wind farm is estimated to generate if it was operational today. There's an "About" section on the site that goes into detail on the various public data sources and how some of the features work. I also document a lot of this on my Twitter @robhawkes if you're curious. This is just the start and there are many more features to come!

SFMTA Retires the Orion, First Hybrid Bus in Cleanest Transit Fleet
SFMTA Retires the Orion, First Hybrid Bus in Cleanest Transit Fleet

San Francisco’s first low-emissions electric hybrid Orion bus
Muni’s Orion hybrid buses are headed for retirement as we phase in a brand-new batch of El Dorado hybrid electric buses. It’s the end of an era for San Francisco’s first low-emissions electric hybrid fleet that travels the city’s toughest routes.
Orion hybrid fleet tackles Muni’s toughest routes starting in 2007
The Orion buses have been a testament to the SFMTA’s commitment to the latest green transportation technologies. Muni, which previously had relied on a diesel bus fleet in coordination with our electric trolley bus fleet, transitioned to its first 30-foot Orion diesel hybrid-electric buses in 2007. This was the start of the SFMTA’s addition of these lower emission vehicles to one of the greenest fleets in the country, ensuring better air quality city wide.
The Orions brought the agency closer to achieving its goal of an all-electric fleet and a carbon-neutral San Francisco by 2040. This is consistent with San Francisco’s Climate Action Plan to dramatically reduce harmful emissions in communities.
The Orions’ pint size made them ideal for winding routes like the 36 Teresita, which weaves through Twin Peaks, Diamond Heights, Glen Park and Bernal Heights. Many riders have taken Orions on their adventures along San Francisco’s curving streets, steep hills and tight turns. One can only imagine their sentimental value, especially among those who frequent the 36, as well as the 35 Eureka, 37 Corbett, 39 Coit and 56 Rutland routes.
The Orions were among the first low-floor hybrid buses to serve San Francisco, and the first with closed-circuit security cameras to help keep Muni riders safe. Their interior was fitted with internal destination signs to help customers know when their stop was approaching. The 30-foot coaches were designed to accommodate easier boarding and provide quieter, more efficient operation.
Their arrival offered us an opportunity to train Muni mechanics on hybrid vehicle maintenance. The agency continued to maintain the fleet even after the Orions’ assembly manufacturer went under in 2012.
The new El Dorados are primed to fill the gap left by their predecessors. Like the Orions, they are low-floor buses with a short wheelbase, making them ideal for navigating San Francisco.
As their taillights fade into the horizon, the Orion hybrid bus fleet takes a much-deserved place in the history of San Francisco transit. They conquered the winding hills of Glen Park and navigated the twisting turns of Telegraph Hill. They will be remembered as the first of Muni’s fleet to pioneer hybrid batteries, moving Muni closer to a zero emissions future.

Show HN: I made PromptWatch – LangChain tracing on steroids As I was building my first few chains, I noticed how difficult it was to understand what was going on, why GPT was responding the way it was, and how I could improve it. Tinkering with my prompts was so tedious - I had to either update the prompt template and rerun the whole chain, or grab the actual prompt, take it to OpenAI playground, tweak it there, and then make a template out of it again. That's why I decided to build something better! PromptWatch allows you to tune your prompt templates in the browser in a format appropriate for LangChain, decoupling template from parameters data. It also allows you to track your sessions and costs per your project and tenant, track template versions and more. Best of all, it's completely free!

At that time everyone was talking about Rust and I really wanted to try it out. I then found Tauri, a framework to build GUI apps with Rust + JavaScript. I was sold. I learned Rust and built the app I always wanted to use. Fast, lightweight and with the ability to connect to multiple clusters simultaneously. Fast forward to today, there’s a few thousand users and I’ve quit my job to go all in on this product. Would love to get you to try the app and share your feedback. It would mean a lot to me!

Show HN: Build AI DAGs with Memory; Run and Validate LLM Tools in Containers https://news.ycombinator.com/item?id=35655777
Show HN: Build AI DAGs with Memory; Run and Validate LLM Tools in Containers I am working on a modular open source framework called Griptape that allows Python developers to create LLM pipelines and DAGs for complex workflows that use rules and memory. Griptape can be thought of as "Airflow for LLMs," providing an alternative to the agent-based LangChain approach. Developers can also build reusable LLM tools with explicit JSON schemas that can be executed in any environment (local, containerized, cloud, etc.) and integrated into Griptape workflows. They can also be easily converted into ChatGPT Plugin APIs and LangChain tools via adapters. Tools can be thought of as any executable code that allows LLMs to interact with the outside world (via ReAct and Toolformer techniques): email, docs, spreadsheets, Jira tickets, web pages/search, etc. The best part about tools is that they can be executed in isolated environments, significantly reducing potential security risks associated with running LLM-generated code and API calls. What do you think? What are some of the use cases that you have in mind for reusable tools? https://github.com/griptape-ai/griptape April 21, 2023 at 09:01AM

Show HN: Plane - Open-source, self-hosted alternative to Jira https://news.ycombinator.com/item?id=35640586
Show HN: Plane - Open-source, self-hosted alternative to Jira Hi HN, I'm Vamsi, the founder of Plane(A simple, extensible, open source project and product management tool). Today, I’m here to share our journey with you all. It all started when we identified some of the most frustrating elements for teams when managing projects, especially with tools that force users to learn complex frameworks. We wanted to create something that was intuitive and easy to use. That's how Plane was born! We first open-sourced Plane back in November 2022, and the response was great. But it wasn't until we announced Plane on Reddit in April that we saw an incredible surge in popularity. In just under two days, our stars skyrocketed from 150 to 1000+! Today, I'm thrilled to report that over 1000+ users are actively using Plane, and many are using the self-hosted version. Our approach is simple yet effective. Despite adding multiple layers of abstraction for project management, Plane operates around the central concept of an issue, similar to a block in Notion. As we continue our journey, we know there's still a lot more to build. We're grateful for the constant feedback we receive from our open-source community, as it's the reason why we're here today. We value your input and want to encourage you to share any feedback you may have. Don't hesitate to ask any questions you may have, as we're more than happy to answer them. Thanks, https://github.com/makeplane/plane April 20, 2023 at 07:30AM

Show HN: InsightFlow Hey everyone, sharing InsightFlow, a (long) weekend project I made using GPT4. I am bit anxious sharing it since I barely knew how to code in Python before but I was simply amazed on how much GPT was able to help me write something that actually works (I hope). My goal was to create a library that empowers people to ask questions from their data, regardless of its source. InsightFlow does just that, it has some modules that allow s parsing information existing in (for now) video (its audio part), html, and in general text and provides a chat interface on top. I would love to expand this to image and eventually video parsing. I know there are some companies that aim for the same but I could not find an opensouce alternative for it. I tried making it modular so different modalities can be added later on. https://github.com/plchld/InsightFlow April 20, 2023 at 05:52AM

But i had different idea for gameplay - instead of guessing secret word, i wanted to make a game where goal is to link two unrelated words. It can be done by placing related words between starting and ending words. In my game there are endless ways to solve same puzzle. There's plenty of room for experiments.

Show HN: A web decision game 99% coded by GPT4. Uses agent to decide win/loss https://news.ycombinator.com/item?id=35624808
Show HN: A web decision game 99% coded by GPT4. Uses agent to decide win/loss Yeah... so I know some software development concepts well I haven't written any code in 10 years, so like half the time was just getting a development setup. At first it suggested PyCharm and honestly it wasted a lot of time. Eventually I got VS Code and GPT just seems to understand it so much better. The real secret to getting good responses with GPT-4 during this I found is to restart the conversation fresh with a complete description of what you need (2-3 paragraphs of detail is great) and the rest as code. [detailed description of what you need, make sure it's detailed and specific add examples if possible] #### [insert all the code, the more you can fit the better] That first code block it gives you back on the first output is the cleanest by far. If there is an error and you submit it back in the same chat conversation, it just gets diluted/saturated over time, hallucinations go up etc. So if there is a bug rather than continue in the same convo, repeat this process in a brand new conversation. Each time it gives a much cleaner, fresher look at the code and goals needed. If your codeblock is really small then this isn't so important, but I'm trying to maximize the amount of code per prompt for best responses. I also make sure to split files by concerns so they don't get too big for the prompt window otherwise it's annoying. #### And lastly the other interesting thing about this project is this simulates an Agent loop where it is constantly trying to determine if the player won or lost, decide what the next most cohesive step is based on the human feedback (click emoji) and looping it. Actually that was my main interest for the project and I just wanted to get something published as a secondary goal. Most of my time was probably spent playing with the prompt and trying to to see if I could get it to determine if the goal was achieved but its actually a hard problem and I have some cool ideas for the next project. https://emojistory.herokuapp.com/As-a-HackerNews-user,-submit-a-Show-HN-post-that-gets-to-the-front-page April 18, 2023 at 11:11PM

Show HN: Magic Happens – let ChatGPT manage your Kubernetes cluster https://news.ycombinator.com/item?id=35604715
Show HN: Magic Happens – let ChatGPT manage your Kubernetes cluster I built this kubernetes operator as a proof of concept this weekend.. It only has a single required item in the spec, a freeform description field. The operator will use chatgpt to generate a spec, then immediately apply it to the cluster. It makes some attempt to correct errors if there's a problem with the syntax. It will leave additional comments, questions or instructions in the status field of the object. I built this in a weekend and it's still quite unrefined. It's in no way production ready, please don't use it for anything real, but it works better than you would think, considering how simple it is. If you're going to use it, run it on a local cluster like 'kind'. Some descriptions to try: * install a redis namespace with a redis cluster and a service in it * create an argocd application in the argocd namespace to install velero. * write a python script that lists all ec2 instances in us-east-1, and run it as a k8s job with the aws credentials already saved in the default namespace.. a somewhat longer description that also worked: given the following spec: --- kind: MagicHappens apiVersion: gptmagic.io/v1 metadata: name: foo spec: description: this is a freeform description field that will be sent to chatgpt to generate kubernetes resources dryRun: false --- Can you create more magic happens resources, each of which describes an argocd application that needs to be created to install a helm chart for one of the standard cluster addons that need to be installed on a cluster for it to be production ready. The description should be be freeform text like the following: "Create an argocd application in the argocd namespace to install istio from the helm chart with all the defaults" or "Create an argocd application in the argocd namespace to install prometheus and grafana, with an ingress enabled for grafana". Be very thorough and included as many apps that might be needed for a prod ready cluster using industry standard CNCF projects if possible. (this produces a list of additional resources for the operator, which the operator then goes on to create argocd applications for -- it also left comments with instructions on one of the resources for how configure it to work with your cloud provider something to note is that since you can run arbitrary containers with arbitrary commands, and chatgpt can write arbitrary code, you don't have to limit yourself to k8s stuff.. if you've got saas credentials on the cluster, you can just tell it to run a python script as a job to do whatever you want. Since most people are cowards, there's a dryRun field that defaults to true, so it only attaches the spec to the object. It is scary how well this works. https://github.com/empath-nirvana/magic-happens April 17, 2023 at 11:39AM
Show HN: Trivai.app – AI powered trivia questions, with references https://news.ycombinator.com/item?id=35604011
Show HN: Trivai.app – AI powered trivia questions, with references Hi HN! As many of you, I've had a lot of fun playing around with LLMs the past few months and I wanted to show you what I've built. I made a trivia website using GPT3 a while back just to have something to play with. My initial interest was to see if I could get structured responses to build a UI around, and if I could get the LLM to refer back to what piece of text it used to create questions and answers with. The initial results were pretty good, but not good enough. Fast forward a few months, GPT 3.5 was released to the public and I was released from my work. I decided to pick this up again and have been making some changes. - I've generated almost 3000 questions. - I initially only let signed up users generate questions due to cost concerns. Since 3.5 is much cheaper, I've opened up the question generation for everybody. - I built a prompt comparison tool so I could tweak the prompt to get better responses. - I've added some more data to the questions. This includes a more free form explanation to the correct answer (separate from the references), and categories for all questions. - I've been working on a question improvement process. This means I collect issues, generate new variations of the question and let people vote on them. Voting and question improvement is currently only available to signed in users. I have many more ideas I'd like to explore, but I would appreciate your feedback and would be happy to answer any questions about the site or its development. You can access the references by pressing the explanation text when you've answered a question correctly. https://trivai.app April 17, 2023 at 10:43AM

Show HN: WikiBinge – discover how all things are vaguely connected (2016) Connect two articles on Wikipedia, but do it the long way. I've always been a fan of the theory of six degree of separation, but it's an overused concept when exploring the Wiki-graph. Instead of showing the shortest path, which in my opinion is "boring" and ends up connecting super-important central articles, I came up with my own method: WikiBinge selects the smaller, less represented articles on Wikipedia. In a WikiBinge path, the underdogs are the kings! How does it work? It's pretty straightforward! Compute PageRank on the Wiki-graph and assign as weight of each edge the PageRank value of the destination node. A WikiBinge path is then simply a shortest path using these weights: the algorithm will then favor paths passing through articles with lower PageRank values. More on the motives to build this here: https://www.jamez.it/project/wikibinge/ This is an older project of mine, but it never got much exposure, so I'm humbly submitting it now. https://www.wikibinge.com/ April 14, 2023 at 10:48AM

Show HN: Dare to Debate an AI? Put Your Skills to the Test with DebateDevil https://news.ycombinator.com/item?id=35568799
Show HN: Dare to Debate an AI? Put Your Skills to the Test with DebateDevil Hi HN community! I am excited to share my recently upgraded website, DebateDevil ( https://debate-devil.com ), an AI chat platform designed to help users practice debates, challenge their ideas, and expand their thinking. I created this site to provide a more objective opinion and help users consider their hypotheses from multiple perspectives. example discussin: ``` AI: The time has come to test your hypothesis and beliefs. I will argue against any topic. What do you want to debate? You: AI will take away most jobs from humans. AI: I understand your concern about AI taking away jobs from humans. However, it's important to note that AI is not designed to replace humans but to augment and enhance human capabilities. AI can handle repetitive and mundane tasks, freeing up humans to focus on more complex and creative tasks that require empathy, critical thinking, and problem-solving skills. Additionally, the increased efficiency and productivity brought by AI can lead to the creation of new job opportunities in areas such as AI development and maintenance. You: While it's true that AI aims to augment human capabilities and increase efficiency, we cannot ignore the potential negative impacts on employment. Job displacement is a valid concern, especially for those in industries heavily reliant on routine tasks. Reskilling and upskilling may be necessary but can be challenging and costly. Additionally, new job opportunities in AI-related fields may not be accessible to everyone, leading to further social and economic disparities. AI: I agree that job displacement is a valid concern. However, it's important to note that technology has always been changing the job market, and AI is just the latest technology to do so. While some jobs may become obsolete, new jobs will be created in other areas. For example, the rise of e-commerce has led to a decline in brick-and-mortar retail jobs but at the same time, created new job opportunities in online retail and logistics. As for the issue of reskilling and upskilling, there are various resources available such as online courses, training programs, and apprenticeships to help workers acquire new skills to adapt to changing job requirements. It's also important for governments and companies to invest in retraining programs to ensure that workers have access to these resources. ``` example judge ``` I think AI is superior in what you discussed; AI focuses on AI's ability to extend human capabilities and points out that new employment opportunities may be created due to the increased efficiency and productivity that AI brings. On the other hand, you are concerned about job losses due to AI, but AI points out that past technological innovations have also changed the employment landscape and that new job opportunities can be created. You also indicate that resources exist for retraining and upskilling to address job losses due to AI, and state that it is important for governments and businesses to invest in these programs. ``` I'm eager to hear what the HN community thinks! Please give it a try and let me know your thoughts, feedback, and suggestions for improvement. Thanks for checking it out! https://www.debate-devil.com/en April 14, 2023 at 05:31AM

Show HN: Google Analytics alternative with the most generous free tier https://news.ycombinator.com/item?id=35539476
Show HN: Google Analytics alternative with the most generous free tier Hi HN, As an indie hacker, the new Google Analytics (GA4) coming motivated me to look for a straightforward alternative that would also be affordable. I had a few basic product requirements and didn’t want to spend too much to replace a free product. There are a lot of great Google Analytics alternatives out there, but the pricing didn’t seem right. As someone who likes to just build things, many of which aren’t businesses yet, it didn’t make sense to pay for options like Plausible and Fathom out of the gate. So I joined with a friend to build Beam Analytics. Beam gives you all the standard web analytics. It also comes with easy to create funnels so you can see how users move through your site. And we have a great proxy for cohort retention that doesn’t need you to log any data with us. It’s cookie-less and GDPR compliant. The free tier is 100k page views per month so hopefully you’ll give it a try. There’s also a Wordpress integration to make integrating with WordPress sites as easy as a single click - https://wordpress.org/plugins/beam-analytics/ . Appreciate your feedback. You can also email us at hi (at) beamanalytics.io or DM me on twitter @TheBuilderJR. https://beamanalytics.io/ April 12, 2023 at 06:40AM
Show HN: NeverPrinter – find and use thousands of nearby printers https://news.ycombinator.com/item?id=35559299
Show HN: NeverPrinter – find and use thousands of nearby printers Hi all, My friends and I have created a Chrome extension and we are looking for feedback on whether people find it useful or not. The extension is intended to serve as a home printer substitute for people (like us) who don't want or need their own printer at home. It makes it easy to send documents to nearby office supply / shipping stores for printing and pickup. Installing the extension adds a printer named NeverPrinter to your list of available printers in Chrome. When you print a document with NeverPrinter, a new tab opens allowing you to select which nearby store you want to send the document to. This is the latest iteration in an ongoing project my friends and I have been working on. We would love to hear any positive or negative feedback. You can get the extension by going to the Chrome Web Store and searching for "NeverPrinter." Or you can visit https://neverprinter.com , which will redirect you there. https://chrome.google.com/webstore/detail/neverprinter-a-home-print/emlbncefhmamggeafbemmmhjkgoadnib April 13, 2023 at 10:48AM

Show HN: PyLLMs: – Connect and compare top AI models in Python Hi HN, We needed a simple way to connect to the top AI models to experiment, prototype and evaluate them. Main features: - Connect to top LLMs in few lines of code (currenly OpenAI, Anthropic and AI21 are supported) - Response meta includes tokens processed, cost and latency standardized across the models - Multi-model support: Get completitions from different models at the same time - LLM benchmark: Eevaluate models on quality, speed and cost The benchmark uses predefine questions to test AI reasoning abilities across a range of "hard" queries. The outputs are then automatically evaulauted using a powerful model (gpt-4 recommended): https://github.com/kagisearch/pyllms/blob/990855968b4bc26ab6... This helped uncover a hidden gem among models: 'claude-instant-v1' which is 4x faster, 2x cheaper and similar quality to 'crowd favorite' gpt-3.5-turbo. https://github.com/kagisearch/pyllms April 13, 2023 at 08:18AM

Show HN: Skip the SSO Tax, access your user data with OSS https://news.ycombinator.com/item?id=35524328
Show HN: Skip the SSO Tax, access your user data with OSS As the former CTO of an Insurtech and Fintech startup I always had the “pleasure” to keep regulators and auditors happy. Think of documenting who has access to what, quarterly access reviews, yearly audits and so on… Like many others we couldn’t justify the Enterprise-plan for every SaaS tool to simply get access to SSO and SCIM/SAML APIs. For Notion alone the cost would have nearly doubled to $14 per user per month. That’s insane! Mostly unknown to people, SSO Tax also limits access to APIs that are used for managing user access (SCIM/SAML). This has proven to be an incredibly annoying roadblock that prevented me from doing anything useful with our user data: - You want to download the current list of users and their permissions? Forget about it! - You want to centrally assign user roles and permissions? Good luck with that! - You want to delete user accounts immediately? Yeah right, like that's ever gonna happen! It literally cost me hours to update our access matrix at the end of every quarter for our access reviews and manually assigning user accounts and permissions. I figured, there must be a better way than praying to the SaaS gods to miraculously make the SSO Tax disappear (and open up SCIM/SAML along the way). That’s why I sat down a few weeks ago and started building OpenOwl ( https://github.com/AccessOwl/open_owl ). It allows me to just plug in my user credentials and automatically download user lists, including permissions from SaaS tools. Granted, OpenOwl is still a work in progress, and it's not perfect. At the moment it's limited to non-SSO login flows and covers only 7 SaaS vendors. My favorite part is that you can configure integrations as “recipes”. The goal was for anybody to be able to add new integrations (IT managers and developers alike). Therefore you ideally don’t even have to write any new code, just tell OpenOwl how the new SaaS vendor works. What do you think? Have you dealt with manually maintaining a list of users and their permissions? Could this approach get us closer to overcoming parts of the SSO Tax? https://github.com/AccessOwl/open_owl April 11, 2023 at 05:40AM

Show HN: Competitive Free-to-Play Match 3 Puzzle Game Hello HN! I'm excited to share with you the competitive HTML5 puzzle game I've been working on for almost 4 years. It's mobile-friendly, completely free to play, and rounds last only 90 seconds. Guivo is a web-based match 3 game where you play rounds with your own board against players from around the world. Ice will spawn along the borders of the board and quickly start spreading, you need to match near the ice to destroy it. The winner of each round earns a spot on the top banner. For each round, players earn Elo ranking points against all users below their rank and lose points against those above. Elo decay starts after 1 month of inactivity, so you will need to stay active to maintain your rank. I'm constantly working to improve Guivo and make it the best match 3 game on the web, I'd love for you to try it out and let me know what you think! https://guivo.io April 8, 2023 at 08:38AM

Show HN: The Future of Data APIs https://news.ycombinator.com/item?id=35464808
Show HN: The Future of Data APIs Hello everyone, I'm Matteo, and, over the last few months, I have been working with my co-founder and other folks from Goldman Sachs, Netflix, Palantir, and DBS Bank to simplify building data APIs. I have personally faced this problem myself multiple times, but, the inspiration to create a company out of it really came from this Netflix article (https://netflixtechblog.com/bulldozer-batch-data-moving-from-data-warehouse-to-online-key-value-stores-41bac13863f8). You know the story: you have tons of data locked in your data platform and RDBMS and suddenly, a PM asks to integrate this data with your customer-facing app. Obviously, all in real-time. And the pain begins! You have to set up infrastructure to move and process the data in real-time (Kafka, Spark, Flink), provision a solid caching/serving layer, build APIs on top and, only at the end of all this, you can start integrating data with your mobile or web app! As if all this is not enough, because you are now serving data to customers, you have to put in place all the monitoring and recovery tools, just in case something goes wrong. There must be an easier way !!!!! That is what drove us to build Dozer. Dozer is a simple open-source Data APIs backend that allows you to source data in real-time from databases, data warehouses, files, etc., process it using SQL, store all the results in a caching layer, and automatically provide gRPC and REST APIs. Everything with just a bunch of SQL and YAML files. In Dozer everything happens in real-time: we subscribe to CDC sources (i.e. Postgres CDC, Snowflake table streams, etc.), process all events using our Reactive SQL engine, and store the results in the cache. The advantage is that data in the serving layer is always pre-aggregated, and fresh, which helps us to guarantee constant low latency. We are at a very early stage, but Dozer can already be downloaded from our GitHub repo (https://github.com/getdozer/dozer). We have taken the decision to build it entirely in Rust, which gives us the ridiculous performance and the beauty of a self-contained binary. We are now working on several features like cloud deployment, blue/green deployment of caches, data actions (aka real-time triggers in Typescript/Python), a nice UI, and many others. Please try it out and let us know your feedback. We have set up a samples-repository (https://github.com/getdozer/dozer-samples) for testing it out and a Discord channel (https://discord.com/invite/3eWXBgJaEQ) in case you need help or would like to contribute ideas!

Show HN: Integrating puzzle rush and spaced repetitions for chess training https://news.ycombinator.com/item?id=35408766
Show HN: Integrating puzzle rush and spaced repetitions for chess training Hi HN! I’m publicly releasing BraiMax Chess, a web app I built during the last three months; it’s based on a training technique which brought me from around 1700/1800 to 2000 rating (superblitz) on lichess. Here it is: https://chess.braimax.com Background story: during lockdown I decided to try and improve at chess, which I was playing online a lot. Bought a few books, tried all the websites and apps I found. This serious study helped a lot in understanding the game better, but didn’t improve my results as much as I hoped. It also was very hard work, and after a few months I stopped having the motivation to continue. Around that time I discovered Puzzle Rush on chess.com; that one was the most enjoyable chess-related thing I could do besides playing games, and it helped with tactics, but I soon plateaued - until I thought about combining that with spaced repetitions. I would manually review the puzzles I had failed, and add them to a rudimentary spaced repetitions system I had hacked together. It was a bit of work, but still enjoyable enough to stick to it; that’s when I started getting noticeably better and better, making fewer blunders, and climbing the rating. Late last year I decided to take some time off after leaving my last job; during the break I felt an itch and decided to create a website which would allow anybody to use the same technique I described above, but in a much easier/integrated way. After three months of full time work on it, it’s ready! Let me know what you think Dan https://chess.braimax.com/play/puzzle_rush April 2, 2023 at 02:36AM
