Show HN: Cassette, a Personal Programming Language I made this simple language over the past year, and it's time for me to say it's "done" (for now) and focus on other projects. I've struggled to answer the question "what is this language for?" other than "it's just for me" — and that's probably good enough. But I also wanted to make something "complete" that others could use if they wanted to. Writing my own language was an incredibly rewarding experience, and I'd recommend everyone trying it. Let me know if you have any questions or feedback, and please share your own experience if you've also made a language. https://ift.tt/xMr4I7k January 1, 2024 at 05:01AM

Show HN: Scan QR codes to check-in guests registered via Google Forms™ Hi HN! I made a no-code platform for creating physical data collection apps, using QR codes [1]. It does not yet have a self-service config UI though, which limits adoption. That's why I recently released a Google Forms™ add-on for QR code check-in, based on the platform. This focused use-case makes it easy to provide a fully self-service config UI. How it works: 1. Create your Google Form as you normally would [2] 2. Activate the add-on if you hadn't already [3] 3. Craft a confirmation email to be sent to each form responder Upon each form submission, the add-on will send a PDF with a unique QR code (a V4 UUID) to the responder. Have guests present this code at the event, and record check-ins in bulk using the included QR scanner. See here [4] for more information, or try the Google Sheets™ version [5] (which doesn't send email). [1] https://ift.tt/73pzedl [2] https://ift.tt/vKJkD45 [3] https://ift.tt/v

Show HN: Meal planning app I built after losing 50kg myself in 2022 1500cals is a calorie and excercise tracking tool that I built after losing 50kg myself in 2022 through simply watching what I ate and starting to exercise. The main "trick" I uncovered is simply to plan meals ahead. It sounds boring, it sounds annoying, but really its such a tiny effort for such outsized and life changing rewards that it should be a no-brainer. The existing tools I found were more focused on tracking after eating which is great in terms of capturing data and measuring over time, but I found really didn’t help me with locking in a routine. I wanted to fix this and bring some of this planning side along with tracking into an easy to use app. This is 1500cals! https://1500cals.com December 27, 2023 at 11:44PM

Here is a video of how I use it: https://ift.tt/ECqP1gH?... We designed it around the principles: 1. Leverage LLMs where they work best: LLMs are faster than humans at putting together prototypes of a few hundred lines of code. By using them early on, and give high level change request commands when the project is small, and then let human devs take over, it’s a productivity boost. 2. non-technical + programmer collaboration: All changes from the app is made as git commits, so that non-technical people (via chat) and programmers are able to contribute to the same code. LLMs are expensive, but we left it open over the christmas holidays for anyone to try it out: https://ift.tt/joJmgVH Would love to hear what you think! https://ift.tt/ydxab7H December 23, 2023 at 12:58AM

After a decade of wanting a simple, lightweight teamwork tool and not finding one, we decided to build one ourselves. We’re calling it Flat, and we have two main goals: 1.

Everything written in Flat would have been written somewhere anyway; Flat just provides an obvious, consistent place to put it. If you check out the demo, please let us know how you think we’re doing on these goals and where we could do better. (Mobile users, there’s a video for you since Flat is desktop-only at the moment.)

Show HN: Canary Checker – An OSS Kubernetes Native Health Check Platform I am Moshe the Founder @ Flanksource, and today we are releasing canary-checker, an open source, kubernetes native health check platform that provides a unified view of health across the entire stack. Canary checker was born out of the need for platform teams (particularly those running on- premise or on less than perfect infrastructure) to understand the health of applications running on top of the platform. Unlike other solutions such as prometheus blackbox exporter, kuberhealthy, and synthetic testing offered by major cloud providers, our approach goes beyond health collection. Canary Checker enables health aggregation by ingesting alerts from Prometheus, Cloudwatch, Dynatrace, and for running full test suites using tools like K6, Playright, Robot, etc.. This approach provides a unified view of system health without the need to browse through many dashboards. Canary Checker can also replace the need for multipl

Show HN: Get any piece of Google Earth as a single normalized glTF 3D model Google released an API in May to get fetch 3D Tiles of anywhere on Earth. Using this in standard 3D engines like Blender is tricky because (1) the tiles are in a geographic coordinate system (2) you get a lot of little tiles at varying quality levels I wanted to simplify this so all you need to do is get an API key, select a map region and a zoom level, and get one combined glTF file that you can throw into any engine. Especially if you're just prototyping and want to see how this data looks in your engine before investing in figuring out all the nuances of the API & coordinate system. (Note that the API prohibits offline use, as in you can't distribute a processed glTF file like this. But you can do this preprocessing in memory whenever you're fetching tiles). https://ift.tt/qPgtGNL December 17, 2023 at 11:37PM

Having super granular roles & permissions in PostgreSQL is desirable, but quite difficult to maintain (particularly at smaller companies without dedicated security/devops/DBA/whatever who make it their business to maintain it). I've thought for a while that having a declarative way to manage them would be really useful and allow more teams to actually make use of sophisticated security features that PostgreSQL offers in their production systems. You can probably see where this is going... I wrote a tool to do just that! It's called sqlauthz, and it allows you to declarative manage your PostgreSQL permissions by writing rules in the Polar authorization language. https://ift.tt/H9qNWhl December 17, 2023 at 02:12AM

Show HN: Octopus – a directed acyclic graph for app development Directed acyclic graphs are muched discussed in comp-sci, but octopus appears to be the first reusable, turnkey, ready-to-wear, off-the-shelf implementation of a DAG for application development, in any language, that I'm aware of. This is remarkable because DAGs hit a sweet spot in the middle of the three common programming paradigms (OO, event-driven, functional). Let's have a DAG as the top-level structure of our applications. Data-fetching and onChange handlers live in DAG nodes, next to the data they act on. The UI flows out from the DAG with fine-grained reactivity. Our app state is effortlessly consistent, because any outside change (user action, api result) unleashes a graph traversal. Our UI components become much simpler, because they just need to dumbly reflect values in the graph. I'm putting this up for a second time. Absolutely no-one bit the first time, which can't be right :-) https://ift.tt/

‘Muni Is My Ride’: A Celebration of Muni Riders and Operators By Sophia Scherr Muni is more than just a system of buses, trains, streetcars and cable cars. It's a living entity that pulses through the streets of San Francisco, connecting riders to the neighborhoods and people that they love. In the vibrant pages of "Muni Is My Ride," artist Keith Ferris and writer Lia Smith invite readers to celebrate the soul of Muni.   The project began as a collection of sketches depicting interesting passengers that caught Ferris’ eye. After a few years, he realized those sketches were something special: a mosaic of people who make up the heart of Muni. Ferris and Smith, who are both passionate about the transit system, found inspiration in each other as the project unfolded. What started as a passenger showcase grew to include portraits of Muni operators.   Ferris and Smith then embarked on a journey (during COVID no less!) to capture the essence of riding and operating Muni.

Show HN: QA GPT – Write UI tests in plain English powered by GPT-4-Vision Hey HN, QA GPT enables engineers and QA teams to write UI and functionality tests in plain english. As engineers, we sometimes get a little lazy when it comes to testing the functionality of our changes. It's hard to switch from coder hat to user hat. However, a single bug can significantly impact users experience and satisfaction. Errors found in production aren't just a nuisance; they're costly. The later a bug is discovered, the more expensive it becomes to fix. I built QA GPT as a proof of concept to make writing UI/functionality tests really easy. It's super simple - just write your test case in plain english and run it. For example: - "Test the new sharing functionality by signing in, selecting a user, and clicking share." - "Log in and try adding a product to the cart" - "Create a new card, view the number of the card, and verify the digits match the face of the car

Show HN: RΞASON – Open-source TypeScript framework for LLM apps Hi HN! RΞASON is an OSS Typescript framework for developing LLM apps that uses Typescript's interfaces to get structured output from an LLM. While there are other TS LLM frameworks, I think RΞASON fills a unique space in the market: it's laser-focused on only three areas and, most importantly, actively stays away from pre-made prompting & retrieval. I've been in the LLM space since GPT-3 originally came out, and I've always had problems with other frameworks, such as LangChain. I dislike that they focus a ton on out-of-the-box prompting & pre-made agents — I , as the dev, should be the one in charge of it. My belief is that LLMs are a new primitive that programmers can use — not a new way to program; it's still up to the programmer to do the right thing & create the right abstractions. Therefore, it's the developer's job to learn the new concepts that come from this new primitive, su

Show HN: Turn any YouTube video into a blog post Hi everyone! This project started with me manually doing the following process: Step 1: Get the transcript from youtube by clicking "show transcript" inside the description box Step 2: The transcript usually won't have any punctuation and have lots of mistakes, so paste it into ChatGPT to clean it up or summarize it. The idea here is to make this process as seamless as possible. What I ended up with was a Chrome extension [0] that adds a button in the YouTube UI that does all of this. Automating it allowed me to do a lot of cool things that would be hard to do manually: 1. I use the sponsorblock database to remove sponsorhsip segments from the video before passing it into ChatGPT. 2. There's also a global cache, so if anyone else has done this process for a video, you see it instantly (rather than having to wait for ChatGPT to type out its response). 3. You can click on any part of the generated summary to jump to the c

Show HN: FireDBG – A Time Travel Visual Debugger for Rust Hey HN, the is Chris, creator of FireDBG. We’ve been working on this debugger just about a year now. Time travel debugging isn’t a new concept, the new idea here is to use call tree visualisation to help us navigate the debug trace. It supports various Linux distros on x64 and macOS on x64 and M1. It’s only available for Rust right now, but we do want to bring this debugging experience to other programming languages. Please give it a try! Would love to know your thoughts. What’s your anecdote in debugging programs? My stupidity is usually in the form of: after a few hours of debugging, I realised I misused a system API (e.g. messing up length with offset) but I kept thinking I had a logic error somewhere.

Show HN: MyYogaFlow – Online Yoga Instructor Hi fellow hackers :) I am an indie hacker based in Switzerland who has been tinkering around with many side projects. Most of the things I developed were for myself or just to get familiar with a specific technology or piece of software. I never really deployed anything so far. Not too long ago, my SO and me bought a deck of cards with different yoga poses on them. Since we both work from our office chairs more than 8 hours a day, we wanted to do something for our body and this is where the yoga idea originated from. After the first 10 minutes of reading through the leaflet and another 30 minutes of choosing the poses and putting them in a somewhat meaningful order, we finally started with our own yoga session. It was clear to me: this is not something my SO wants to do every day. Doing the same order of poses every day wasn't an appealing alternative either. Away with the cards and on the lookout for an alternative again. Hence I starte

Show HN: wallstreetlocal – View investments from the world's biggest SEC filers Hello Hacker News! My name is Anonyo, and I am a seventeen-year-old from Southeast Michigan. This is wallstreetlocal, my passion project for the last year. The United States Securities and Exchange Commission (SEC), forces institutional money managers whose portfolios surpass $100 million to quarterly update the SEC website with their latest investments. These money managers, known as 13F (the form type of the report) filers, are the biggest investors in America, and the law forces them to publicly reveal their investments. The problem I found was that SEC filings are cumbersome to find and view. To remedy this, wallstreetlocal saves and formats SEC data by bulk in an easily accessible format. Other websites do the same thing wallstreetlocal does, but wallstreetlocal places an emphasis on stock data. You can compare prices over time, view gains, and even download the data yourself to make any conclusion

Show HN: WarpBuild – x86-64 and arm GitHub Action runners for 30% faster builds Hey HN, I’m Surya and I’m excited to show you WarpBuild! WarpBuild provides fast, secure `x86-64` and `arm64` Github actions runners. This speeds up your workloads by 30%, at half the cost, and takes ~2mins to get started. We’ve been seeing pretty good results since we opened up signups a week ago and I’ve shared some numbers publicly here [1]. Currently, we support linux runners for Github organizations (not personal accounts) and MacOS support is coming soon (~Jan). The way the runners work is deceptively simple: Runners are assigned to hardware that is ideal for build workloads with fast NVMe disks and high single-core performance. The runners are allocated on VMs, not containers. This provides faster performance and enables use cases requiring (1) nested virtualization for running firecracker and other hypervisors, (2) k8s without relying on kind, and (3) Android emulators on `arm64` instances in test w

Show HN: Solving NYT Connections with ChatGPT Just for fun I decided to see if I could use chatGPT to solve NYT Connections word puzzles. It uses a pretty straightforward BFS search in which the LLM is first prompted to generate several possible groupings of four related words, and then a different prompt is used to evaluate the soundness of each of those groupings. This approach seems to be able to produce the correct solution somewhat less than half the time. Some observations: * For whatever reason, chatGPT-4 seems to be a bit worse than 3.5 at generating Connections groupings. I haven’t tested systematically so maybe this is just some small sample size bias. But at the very least it isn’t obviously better * It really struggles with the “words that can fill in the blank” style groups. Often it will correctly come up with the right category (e.g. “words that can precede `cheese`”) but will only be able to identify 2 of 4 words in that grouping * It frequently generates very vague cat

All you have to do is import any Python scripts/libraries, declare UI components, and layer app permissions so you can share them with others. We’re a middle ground between Airplane and Retool—simpler UI creation than Airplane, more code-centered than Retool. UI building is declarative and you can bind Python scripts/functions to UI components. You can write Python scripts/functions using our App Studio with support from a Python Language Server Protocol (LSP) for linting. Since the self-hosted worker directly references .py or .sql files in the filesystem, you can even write them on VSCode directly or import any other Python script or library.

Customers will need to create a new user account with the new MuniMobile® app as accounts are not transferrable. Anyone with active tickets on the previous MuniMobile® app can use those tickets until they expire or until Jan. 15, whichever comes first.   However, as of today (Dec. 4, 2023), customers using the previous MuniMobile® app will not be able to buy new tickets.

I've also added knobs that let you "circuit bend" the encoders, changing parameters that would normally be inaccessible to the user to get strange glitchy sounds. The plugin lets you switch between two MP3 encoders, since under the MP3 standard, the specifics of what to lose in MP3 lossy compression is left up to the encoder. The encoders are LAME, the gold standard for open-source MP3 encoders, and BladeEnc, an old open-source MP3 encoder that has a really bubbly sound and was fun to work with.

All of the posts on the site come from real journalists. They are who they say they are. I know journalists are not always held in the highest regard on this site, but I will point out -- their livelihoods come from a reputation for accuracy.

That's what we expect, and it's listed right in our Editorial Policy. ( https://ift.tt/tQDKfGz ) Please let me know what you think, and if you find this helpful. Jared https://www.forth

Show HN: I made feature-rich and free VS Code extension to use GPT-3/4 (PaLM2) Hey HN, I am a software engineer and solopreneur who has recently been delivering a bunch of apps. While coding, at the beginning of the year, I developed my own VS Code extension, which I've been using for coding tasks and assistance from top AI models like GPT-3/4 and Google PaLM2. After a while, I realized it would be good to publish it, so I integrated it into an existing SaaS, which I had previously launched, named SnippetHub, and the extension is called SnippetHub Lens AI. Why Lens AI? Well, because one of the unique features is that you can create as many CodeLenses as you want, for which you can define custom AI instructions and target points in code, so you will have a little clickable links (CodeLens) above target points (methods/classes/variables...). The result is that you have a pre-defined AI buddies which you trigger on a piece of code and do some AI magic, with just one click. In addition
