Show HN: An app that takes your money if you don't reach your goals https://ift.tt/LnrjGwC

Show HN: An app that takes your money if you don't reach your goals My wife and I just launched this app because we had so much fun with a fitness challenge we did we some friends recently where everyone put in $100 and defined their goals, then only the people who met their goals split the pot. It made us realize there's really no better motivator than money. It's better on mobile screens right now as we just designed for mobile screens for now. And we did manage to put it up on both app stores - it's low in the ranks but you should be able to search it by "Goalie challenges". We built it using the leanest tech stack - Ruby on Rails, server-side HTML (no JS), tailwindcss, then packaging it for iOS and Android using pwabuilder! https://goaliemvmt.com/ April 19, 2024 at 04:32AM

Show HN: MonsterWriter – Write a thesis, post, or organize notes https://ift.tt/hlJvqCt

Show HN: MonsterWriter – Write a thesis, post, or organize notes Hello HN, in 2017 I started a project that would become MonsterWriter. First envisioned as a semi-structured wiki it became a writing application specialized for scientific content. It is a perfect tool if you write your thesis. While it is focused on technical content, you can still see the knowledge management spirit in it. One or two years ago, my wife joined me in my efforts and redesigned the whole project and we recently released it as MonsterWriter2. To celebrate this milestone we are giving away free lifetime licenses for the Desktop version (till Apr 28). Just use the promo code "gu0ho4q" for a 100% discount. You can find detailed instructions here: https://ift.tt/XVLnrSc You can also find a short introduction video to the app on YouTube: https://www.youtube.com/watch?v=vR8i-EY_UBk We are happy to receive any kind of feedback!

Show HN: Trained Tiny Tales GPT(30M model)from scratch and deployed in $15 https://ift.tt/dQuOR1h

Show HN: Trained Tiny Tales GPT(30M model)from scratch and deployed in $15 For the last few weeks, I have been working on training an LLM from scratch and deploying it in production on Google Cloud Platform. Finally, I trained a 30 million parameter model on 1 billion tokens and deployed it as a web service. You can access the LLM using this site - https://ift.tt/kliWMvh The following steps were taken to build Tiny Tales GPT 1. Downloaded and preprocessed 8GB of dataset using multiprocessing library. 2. Tokenized the data using byte pair encoding to create 1 billion tokens sharded in different bin files. 3. Defined a training setup and trained the model on a small version of the LLaMA model architecture with 30 million parameters. 4. The training was done using Distributed Data-Parallel on two A-100 GPUs provided by JarvisLabs.ai (they are most cost-optimized) 5. After the training is done, an inference script is created to predict the tokens from the trained model given the input context vector. 6. Developed REST-based API service using Flask framework to interact with the inference service to the end user. 7. Finally used GCP's virtual machines, instance groups, load balancers, and DNS services to deploy the service on the internet. https://ift.tt/Cx93Mdo April 18, 2024 at 02:25AM

Show HN: A no-watermark video downloader for Any social media https://ift.tt/kNIWKpD

Show HN: A no-watermark video downloader for Any social media Hi HN reader, I'm a solo-founder navigating product market fit. I've spent 3 years building Double Subtitles which I am very proud of, but I don't know how to do marketing and my growth is somewhat stagnant. Through learning about SEO, I discovered this opportunity that I want to share: There are a lot of websites that let you download social media videos, which have extremely high traffic. But they are all disjoint, in the sense that some download TikTok videos, while others download Instagram videos, others YouTube, etc... I quickly prototyped software which downloads any video from any link. Currently the live version of FastDownload only supports TikTok and YouTube videos, since they are the most stable. But I will slowly start rolling out Instagram and other services weekly. ps. Personally, what I think is really cool is this Apple Shortcut, which lets you download videos directly from within whatever app you're in, using Share Action Extensions. pps. Another thing I'm very excited about is that while doing analysis with Ahrefs and SEMRush I have been able to identify many high value keywords which I'm deploying pSEO strategies for now. I hope this product is helpful and any feedback (even negative) would bring me joy. All the best, Bojan https://ift.tt/jiHtYRL April 18, 2024 at 02:33AM

Show HN: Building a GPS receiver https://ift.tt/Y3PQGAZ

Show HN: Building a GPS receiver Hi everyone! Shortly after publishing my iOS 4 jailbreak last October[1], I got to work on my next hobby project: a from-scratch homebrew GPS receiver, which can solve the user’s location solely from billions of radio antenna samples. I took a commodity SDR (alongside the Python standard library and numpy) and built a signal processing pipeline that can detect and track GPS satellites over many minutes, drop and pick up satellites as they come in and out of view, and precisely determine the user’s position and clock inaccuracy. All told, gypsum can go from a cold start to a fix on the user’s position, and the precise time, in less than a minute of listening to the antenna. I went on a journey of learning how to detect and track satellite signals that are literally too quiet to hear, and I hope that some of the magic comes through in the posts! After implementing this myself and walking the long road of getting it working, I’m left completely stunned by the brilliance of GPS, across so many axes. I hope you enjoy the read! On a more personal note, I’ll be starting a new job next week which isn’t as amenable to publishing side projects, and therefore this will be my last publicly-published project for some time. I’ve had great experiences making and sharing projects on here, and I’m really grateful for the positive feedback that’s been shared!

Show HN: Docker-boot – Run a system from RAM without LiveCD https://ift.tt/uEbGfOK

Show HN: Docker-boot – Run a system from RAM without LiveCD How often do you screw up the system so much you have to reformat the disk (without losing data) to fix it? Well, sometimes I do, and sometimes I can't be bothered to burn a live ISO onto a USB stick. There's initramfs, but it's hardly a pleasant environment, with network configuration and all. My go-to solution has typically been to create a chroot with busybox and a few utilities in /tmp, chroot into it, and then kill services that use the solid drive so that I can unmount it. That's an error-prone process, and sometimes systemd itself uses disk, so you can't unmount the drive despite killing all the userland but PID 1. This script improves the UX. It uses a Docker image as the chroot base, which is much easier to tailor to your needs, and automagically commits all the atrocities, such as tearing down all the userland processes, including PID 1, and re-spawning the host system from the container filesystem. It also drives libostree and Nix users mad, because it can be used to try out a new DE or even a whole OS without polluting the host filesystem or spawning a virtual machine. The video in the README shows me trying out KDE + SDDM from a host running GNOME + GDM3. https://ift.tt/DSRsWjK April 14, 2024 at 11:08PM

Show HN: Using Google Sheets as the back end/APIs of your app https://ift.tt/KieQlf1

Show HN: Using Google Sheets as the back end/APIs of your app Hello everyone! At a company I worked for, we needed to develop an MVP (basically a web page) and apply certain business logic to a Google Drive spreadsheet that was frequently updated by the Sales team. In this case, we had two options: Develop a backend to replace the current spreadsheet and have the sales team use it as a new "backoffice" - This would take a very long time, and if the hypothesis we were testing was wrong, it would be time wasted. Create the web page and use Google's SDK to extract data from the spreadsheet. We chose to go with the second option because it was quicker. Indeed, it was much faster than creating a new backoffice. But not as quick as we imagined. Integrating with Google's SDK requires some effort, especially to handle the OAuth logic, configure it in the console, and understand the documentation (which is quite shallow, by the way). Anyway! We did the project and I realized that maybe other devs might have encountered similar issues. Therefore, I developed a tool that transforms Google spreadsheets into "realtime APIs" with PATCH, GET, POST, and DELETE methods. Since it's a product for devs, I think it would be cool to hear your opinions. It's still quite primitive, but the basic features already work. https://zerosheets.com https://ift.tt/43MaiOy April 12, 2024 at 09:59PM
