Show HN: JinbuPal – Learning Chinese doesn't have to be difficult https://bit.ly/3xyzBiR

Show HN: JinbuPal – Learning Chinese doesn't have to be difficult My co-founder and I built a Chinese language learning web app that helps you quickly master the most common Chinese characters and recognize 95% of real content. JinbuPal uniquely enhances learning for maximized progress by allowing effortless personalization of your daily study. When I dreamed up JinbuPal, I was a maker just like others in the HN community. I was working on my electronic hardware startup and I thought that learning the fundamentals of Chinese would help me communicate with manufacturers in Shenzhen. We designed JinbuPal to help you leverage data and your own curiosity to learn as fast as possible. JinbuPal is built for (and by) analytical thinkers with a desire to “hack” Chinese learning and easily identify the “low hanging fruit” to speed up their learning process. We’ve selected the highest impact characters and words, allowing you to make more substantial progress gains with your early study. JinbuPal provides countless ways for you to filter and sort cards, identifying the easiest content for you to learn each day based on your current level and your own curiosity. As you familiarize yourself with characters, you can also utilize these filters to study words which only include characters you are already familiar with. JinbuPal boosts confidence by giving you real-time feedback of how well you can apply your Chinese skills in the real world. We do this with the JinbuPal Score, which is a metric for what percentage of Chinese you should recognize on average in real content based on our analysis of millions of characters of Chinese text. We then help you to find authentic Chinese content that actually interests you. Finally, you can see your JinbuPal Score come to life by pairing your account with the JinbuPal Chrome extension, analyzing webpages, and visually seeing in your browser how much Chinese you’ve already studied from any given webpage. Once you complete the content in JinbuPal, you should recognize, on average, around 95% of Chinese characters you encounter. Please take a look at the explainer video embedded on our webpage and register for a free account. I gladly welcome your feedback and anything you’d like to share about your own experience learning Chinese. Thanks! -Mike https://bit.ly/3xqSog7 February 16, 2023 at 02:45PM

Show HN: Vircon32 – A virtual, simplified 32-bit game console Vircon32 is a virtual game console designed from scratch to be as simple and portable as possible. Its main focus is to actually have interesting games to play, rather than just being a programmer sandbox. Console features are in line with the 32-bit generation (PSX/Saturn): true color, transparencies, CD-quality audio, memory card... But to keep simplicity, this is a 2D machine only. https://bit.ly/3EcwK3c February 16, 2023 at 01:40PM

Show HN: I made a super simple iOS app to track expenses https://bit.ly/3k3WiIO

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://apple.co/3xspTic February 16, 2023 at 10:17AM

Show HN: Rust+Svelte=Terminal Link to project: https://bit.ly/3ACXBDs Demo: https://youtu.be/ZjAXMMMoKGg This project aims to create a terminal with functionalities that improve the experience of using terminals. Examples of useful functionalities would be autocomplete suggestion, showing the current branch of a project, prepared scripts that can be reused, and others. You can come up with your ideas. The project uses technologies such as Svelte on the front-end, which offers flexibility regarding the implementation of the interface. On the back-end side, the most important part is the PTY. All the back end is implemented in Rust. The basic framework of the project is Tauri. At the moment the terminal has suggestions only for some commands (cd, ls). To support more commands it is needed to add them in the Manter's "library" located at src/cli/library/library.ts. It is possible to have custom script based suggestions. For example if we write in the terminal “git checkout” and after we press Space, a dropdown will appear with all available branches. A good analogy to understand the purpose of this project is the following - traditional terminals are like simple code editors while this terminal is like an IDE. Anyone is welcome to contribute to this project with and ideas. Imagine the terminal you would like to use. Feel free to open any issue with suggestions and bugs. February 15, 2023 at 02:46PM

Show HN: Impact of using 1 or 2 sticks of DDR5 on a 6800HX with 680M IG https://bit.ly/3EaHLBY

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 10:55AM

Show HN: Explore careers that you don't know even exist "Excited to launch CareerGPT.ai on Hacker news today! We're on a mission to help people ..yada...yada" No, that's ChatGPT's writing, not mine :) Folks, I was a PhD student once, in a non-home country, and just wished to know what was it like to go and work in the industry, being a programmer, or started a company. Torn apart between choices, I just wished there was a totally unbiased counselor to talk to. I couldn't do that with my supervisor since he always encouraged me to finish the thesis (of course). Heck, had ChatGPT exist back then, I would have had more infos and made decision easier. So why not launching one, on the back of the collective "intelligence" and "creativity" of large language model. About building the product: Yes, I call OpenAI's API, but need to do some 'prompt engineering', updating temperature along the conversation. Just tell me what you think. Thanks. https://bit.ly/3S3u8KI February 15, 2023 at 10:39AM

Show HN: Openapi.security, a fast security checker for REST-based API https://bit.ly/3lFYzuk

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://bit.ly/3RZjuV2 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://bit.ly/3RZjuV2 February 14, 2023 at 07:58PM

Show HN: Lockval Engine – a distributed back end KV engine that can run scripts https://bit.ly/3K0F3Tj

Show HN: Lockval Engine – a distributed back end KV engine that can run scripts I've been developing game backends for several years, using and designing a lot of code. They all about calculations, synchronization with front-end data, and database data, and try to ensure consistency, atomicity, and high response, etc. However, these codes and frameworks have always had problems such as very complicated APIs, incomplete or non-existent ACID, multiple calls to RPC, and non-real-time full or semi-full data landing. So, we created Lockval Engine. An easy-to-use, ACID, distributed, DOP, multi-language support backend engine. Here are some online demos that will give you a quicker understanding of Lockval Engine: [APIdemo] https://bit.ly/3lxex9Q [playground] https://bit.ly/3Yrp19f... https://bit.ly/3Yv9jdg February 13, 2023 at 01:12PM

Show HN: My personal medical knowledge system https://bit.ly/3HVckwp

Show HN: My personal medical knowledge system Since medical school years ago, I have been trying to find way for long term knowledge management and retention. I finally ended up with Obsidian on the desktop, but it's still difficult to access my knowledge anywhere online, until I made my own online wiki. Things that helped me get to this step: 1. "How to Take Smart Notes" 2. Evergreen notes by Andy: https://bit.ly/3xhsyLB . This website shows the culmination of my personal knowledge with search bar. The idea is that I should be able to find what I'm looking for within seconds, otherwise the title of my notes are not specific enough or the web of knowledge is not good enough. Most of the notes still have short title style and walls of texts, but the newer notes that I added are in evergreen note style. I'm slowly converting them to permanent notes. Good example pages of permanent notes: https://bit.ly/3HYJRG5 https://bit.ly/3jWuje2 The website is made with Astro for better static site generation. Notes are taking in markdown format in Obsidian, and I used a script to copy them over that runs on schedule. I I tried Sveltekit first, but with several thousand markdown notes, I was not able to render the website on Netlify. CSS is done with tailwind. Search is added with Minisearch. This was a very fun project. Everything from the search function to the subtle fade animation was satisfying to add. https://bit.ly/3HYJTOd February 14, 2023 at 12:03AM

Show HN: I made a community-based writing application https://bit.ly/40PtDYw

Show HN: I made a community-based writing application Hi HN! Writing has been a big part of my life for the last few years. It's helped me make sense of the world around me through journaling, and my blog and technical books have made wonders for my career as an engineer. Something I've always been missing is an online community where I can practice my skills and learn from other aspiring writers. I built Tavern, hoping to solve my own problem. Its main concept is that every Monday everyone in the app gets asked the same writing prompt and you have seven days to submit your answer. You can look at what others have posted, but only after you've submitted your answer. My hope is that this way I will reduce lurking and encourage more people to actually write rather than think about it. There is a concept of giving likes (ales, since the whole app is tavern-themed), but I've given it a twist by not showing the number of likes an answer has until you like it. Also, answers are always sorted by date, with the latest ones on top. This way if you open Tavern three times this week you'll be able to scroll until the last answers you've read and leave, they won't get shuffled. Tavern's not a technical wonder by no means - you can probably put it together in a hackathon. But I put a lot of effort into the design and its simplicity, so people can focus on the content. I have more plans for it in terms of features but I wanted to launch the bare-bones build as soon as possible. Hope you like it! https://bit.ly/40Ksphf February 13, 2023 at 09:07AM
