Show HN: I made a super simple iOS app to track expenses My Expenses is a very simple app to track expenses for one-time budgets. Let's say you're going on vacations in Italy and you want to allocate $1.500 to this trip. You create a budget "Italy" in 30 seconds and you're ready to go. Each time you make an expense in Italy, you add it to the app in a few seconds and you instantly know you're remaining budget. I'm bored of super complex apps. Yes, they do a lot of things, but it often takes a while to get used to the app and understand all its features. That's why I created this app. I want people to be able to track their expenses in seconds, as quickly and simply as possible. It's available on iPhone, iPad and Mac. https://ift.tt/MTS1zPn February 16, 2023 at 02:47PM

Show HN: Keep – Open-source alerting CLI https://ift.tt/VYr3K9O

Show HN: Keep – Open-source alerting CLI Hi Hacker News! Shahar and Tal from Keep here. We're thrilled to announce that we're open-sourcing our alerting CLI tool, Keep ( https://ift.tt/vEBUXAQ ). Designed by developers for developers, Keep streamlines and simplifies alerting, making it a first-class citizen within the development process. Think of Keep as Prometheus Alertmanager but for all observability tools, with a simple and intuitive (GitHub actions-like) syntax. We believe that alerting has historically been neglected in existing monitoring platforms, leading to subpar alerting practices. With Keep, we aim to change that. Although it's still in its early stages, we would love to get your feedback on our project. Keep provides the following key features: 1. Declarative alerting that can be easily managed and versioned in your version control and service repository. 2. Alerts from multiple data sources for added context and insights. 3. Freedom from vendor lock-in, making it easier to switch to a different observability tool if needed. Some of the features we plan to add in the future include: - Integration with CI/CD processes to simplify alerts maintenance and testing. - Scoring system to assess the alert's urgency and provide relevant information. - Slack integration to keep track of alerts over time. - More providers, conditions, and other enhancements. We invite you to give Keep a try ( https://ift.tt/vEBUXAQ ) and share your thoughts with us. Your feedback will help us make Keep the best it can be. https://ift.tt/vEBUXAQ February 15, 2023 at 10:13PM

Show HN: Impact of using 1 or 2 sticks of DDR5 on a 6800HX with 680M IG https://ift.tt/93htfI7

Show HN: Impact of using 1 or 2 sticks of DDR5 on a 6800HX with 680M IG A few months ago, I ordered a Minisforum UM690 for work. For less than 500 bucks, this little beast is equipped with the incredibly powerful 8 cores / 16 threads Ryzen 9 6900HX (4.9GHz) and an integrated RDN2 680M graphics card (the single thread performance of this mobile CPU is just 10% lower than my home 5800X desktop PC). I do some light gaming on my lunch break, and I was pretty impressed by the gaming performance of the 680M. Because of budget constraints at the time of ordering, I could only afford a single stick of Gskill - RipJaws 16 Go DDR5 4800 MHz CL34. I made a few benchmarks on multiple games, but most games I play do not come with a proper benchmark loop, so I used Unigine Superposition Benchmark to make a proper benchmark. Single 16 GB stick, 1080p, medium settings: 3022 (18.85 min fps, 22.61 avg fps, 31.85 max fps) Those results were good for an IGPU, but I saw a few articles saying that having two sticks instead of one could improve performance (never backed up with benchmarks or hard numbers). So I bought another stick. Here are the results with two sticks: Dual 16 GB sticks, 1080p, medium settings: 4969 (31.66 min fps, 37.17 avg fps, 48.96 max fps) Yep, this is a whopping +65% with two sticks! So, if you use a CPU with an integrated graphics card, you should use 2 sticks! February 15, 2023 at 03:25PM

Show HN: Openapi.security, a fast security checker for REST-based API https://ift.tt/K50NquE

Show HN: Openapi.security, a fast security checker for REST-based API tl;dr we released openapi.security, an online tool that performs a dozen of security tests on any given openapi/swagger-based API, with no signup or email required. You can try it here: https://ift.tt/x5r6ldH My team at Escape (YC W23) is mainly focused on securing GraphQL APIs. For this, we developed a new approach called Feedback driven API Exploration. Basically, we infer the right security tests cases to run using the specification and a carefully crafted in house graph traversal algorithm. (It's a bit long to describe here but we published a more in depth explanation of how this algorithm works in our blog!) We recently wondered if this Feedback Driven Exploration approach could be efficiently applied to good old REST APIs as well. From our experience, well designed GraphQL and REST APIs are quite equivalent: both have an organized data structure and explicit relationships between objects. So why wouldn't it work? We often organise internal hackathons. So this time, we focused on this experiment, adapting our algorithm to REST and ending up creating our last side project: OpenAPI.security. It is a very simple tool: anybody can enter an OpenAPI / Swagger spec, and openapi.security will run a bunch of security tests on it and give back a report. It's designed to be fast and smart in the way it analyzes input specs. https://ift.tt/x5r6ldH February 15, 2023 at 12:28AM

Show HN: I made a game, Tippy Coco https://ift.tt/FLYIfMT

Show HN: I made a game, Tippy Coco Tippy Coco is a volleyball game in the browser. You can play with a friend at the same keyboard, or solo challenge the built-in opponents. As for the tech: it's all TypeScript + HTML5. I did not use a game engine; I just made a game loop with setTimeout and the artwork is all just png's drawn on the canvas. The sound is played through the HTML audio API. Input is watching keyboard events and the Gamepad API. One thing: I know this is 2023 but it's not a game for phones. It's for a laptop or desktop PC with a physical keyboard. It also works ok on an iPad with a physical keyboard. Tippy Coco is free and without ads.

Show HN: Generate User Interface Components with GPT-3 https://ift.tt/FfJasXi

Show HN: Generate User Interface Components with GPT-3 I’m building an experimental tool that can generate a UI component from a high-level text description, i.e. “Design a card for viewing goals in a goal tracking application”. Basically, stable diffusion but for user interface components instead of images. This tool is at best a proof of concept. It currently only generates a single type of component (small cards that have basic info about an object), but the goal is to be able to design entire applications (either in one fell swoop or by piecing together components that the tool generates). The components it generates can be exported as react code. You can also have it modify an existing design. The tool isn't useful yet but it's somewhat fun to play around with. Having it generate a component rather than an entire screen made the problem easier but I'm not sure if there are any users that this would appeal to. I could see it appealing to developers who lack design and CSS skills and want to quickly build a decent looking frontend for their app. Looking forward to hearing what you guys think of this project and the generative AI for UI space in general.

Show HN: Sign-up flows from 100s of websites made publicly available https://ift.tt/aG8OfY5

Show HN: Sign-up flows from 100s of websites made publicly available Hi HN! Fil here from Formsort ( https://formsort.com/ ). We just launched Fineflows, a design gallery that showcases leading sign-up flows from around the web. Why? My team has been building sign-up flows for close to a decade across mortgages and healthcare. We’ve spent a lot of time working through the technical and design aspects of this problem, such as state management (getting that pesky back button to work), design flexibility, and data enrichment. Time and again, we’ve seen product teams who don’t know what to build even though they can . Often times, builders of forms start their process by looking at what other people are doing, answering questions like: What are different ways error validations are done? Should I use photos of people, or is text enough? Is it appropriate to use emojis in forms? How can I decline a user in a polite yet firm way? To that end, we set out to capture as many different form flows as we could and make them available. We’ve found it to be an invaluable resource ourselves, and many of our customers have used it to improve their own designs. I’m always shocked by how often people reinvent the wheel instead of using a tried-and-true technique, and I hope that we’re helping address that problem. Take a look at the gallery at ( https://ift.tt/5ukZ460 ), or head to Formsort’s homepage to start building yourself! Would love to hear any feedback, inspiration, or thoughts, as we are just getting this off the ground :) https://fineflows.com February 13, 2023 at 11:21PM

Show HN: Meta peddling unsecured business credits to users in India https://ift.tt/Mo6ANRY

Show HN: Meta peddling unsecured business credits to users in India I have a friend who owns a business and they got a really weird email from meta. Apparently meta has teamed with "Indifi and FlexiLoans" to give unsecured business loans. 1. They are sharing details of "this user is a small business owner" with third parties and that they are directly emailing about "helping businesses in need". What the hell is wrong with these people. If I wanted a loan,i would approach my bank and not some fincorp who would fleece me with 18% interests. Banks have much less interest rates February 13, 2023 at 04:03PM

Show HN: Forever-Time Multi-player- Play with your loved ones after you're gone https://ift.tt/PB9AGUu

Show HN: Forever-Time Multi-player- Play with your loved ones after you're gone Summer Friends Don't Stick Around is a "forever-time" multiplayer game created to immortalize players and give others a chance to play with them "in spirit" even after they are no longer with us. In the "Remember Me" mode, players can train a neural network to capture their play style. The output is a data model that can be shared with friends and family. Your playstyle is essentially encoded in the data model. In the "Remember Them" mode, players can load a data model file and play with them. I'm still learning more about neural networks and tweaking them to capture more of how any particular player approaches the game. There is room for improvement. https://ift.tt/MBxbiUI February 13, 2023 at 01:05AM
