Show HN: ESInfer – Make JavaScript Type-Safe https://ift.tt/uIiLZot

Show HN: ESInfer – Make JavaScript Type-Safe Hello, folks. I'm Jiang, the author of ESInfer. I love writing Javascript because it has a prosperous ecosystem and is quick to get my hands dirty. However, sometimes it's painful when the flow is not fast to follow due to the lack of a type system. To solve this, I wrote ESInfer, a statical inference tool, to automatically type check and generate type annotations for Javascript. It works with pure Javascript without any add-ons to the language or user-space code and supports highly dynamic features, such as the modification of prototypes. It is still in the very early stage, which offers almost all ES5 features and a select set of ES6 features like array/object destructing. I'm working hard to bring all ES6+ features into it incrementally. If you heavily use javascript/typescript and do NOT want to write the type annotation sh*ts anymore, give it a try :) https://esinfer.com/ October 15, 2022 at 06:03PM

Paratransit Services 2022 Update

Paratransit Services 2022 Update By Erin McAuliff This past year, the SFMTA’s paratransit programs safely provided close to half a million trips to older adults and people with disabilities around San Francisco. These services provide door-to-door transportation to people unable to independently use the Muni system. They include SF Access P aratransit , Group Van service , Shop-a- Round shuttles, the Essential Trip Card Program (ETC) and the Van Gogh Recreational program.   In addition to traditional van services, the SFMTA partners with the local taxi industry to provide cost-efficient and customer-friendly taxi options. Payment is accepted in every San Francisco taxi, including accessible ramp-equipped taxis, with the swipe of an SF Paratransit Taxi debit card.    Here are a few accomplishments staff at the SFMTA and Transdev (the contractor responsible for managing SF Paratransit services) have been working on behind the scenes to improve our service offerings and cont

Show HN: Reverse Engineering an Old Digital Back Raw File Format https://ift.tt/tz4cyN3

Show HN: Reverse Engineering an Old Digital Back Raw File Format Perhaps a bit outside of the typical interest of HN readers, but I wanted share how I went about figuring out how to convert the RAW files from a digital camera (well, digital back) that originally came out in 2004 to DNGs. An interesting fact about these digital backs is they use an Intel Xscale CPU! - the PXA255 https://ift.tt/oat2sYW October 15, 2022 at 12:33AM

Show HN: Circumflex, browse HN in your terminal https://ift.tt/TSrVnbJ

Show HN: Circumflex, browse HN in your terminal Some two years ago, I found myself spending a lot of time in the terminal between learning vim and discovering new command line tools. I was surprised to see that the niche of HN clis was (relatively) small, and so I decided to write my own command line tool for browsing HN called `circumflex`(`clx`). `clx` is written in Go using Bubble Tea[1]. You can read the comment section or the linked article in reader mode in the pager `less`. Using `lesskey` to add custom keybindings, the replies can be collapsed and expanded in real-time (but not individual replies, only all replies at once). Behind the scenes I am appending invisible unicode characters to each line so that I can use the custom keybindings to filter them out. The same technique is used to allow for jumping between top-level comments. I spent a lot of time thinking about syntax highlighting and finding relevant bits to highlight while also not going overboard with colors. The end

Show HN: Using AI to write picture books https://ift.tt/Uki87Dc

Show HN: Using AI to write picture books Ever wanted to create your own picture book? Introducing Mr. Seuss! Just input images of your protagonist and a basic storyline and he'll produce a (funny but weird) picture book for you using AI. The linked colab uses GPT-J to generate a story and Dreambooth Stable Diffusion to generate relevant pictures to the story. It's completely free and takes around 30 minutes to run on the free tier of colab. Let me know what you think in the comments! So excited to see what's possible for storytelling using AI. https://ift.tt/AiMTDQg October 13, 2022 at 11:15PM

Show HN: Obsidian 1.0 https://ift.tt/BobqsTA

Show HN: Obsidian 1.0 Cofounder of Obsidian here. We're excited to announce Obsidian 1.0 is live! Obsidian 1.0 introduces two big changes: a UI overhaul and an new tabbed interface. We've put a lot of care into making the app more approachable and more accessible. We've also prioritized using more native OS features for menus, windows, and many details. We got our first private beta users from a comment under a HN thread about org-roam [1], and our waiting list was an innocent Google Form. Good times! Our initial launch on HN was over two years ago [2], when terms like "second brain" and "tools for thought" were still in their infancy. Since then, the landscape has continued to evolve and new ideas are sprouting in the space every day. Obsidian has always embraced its "hacker" nature and thrives off its community of tinkerers. We now have over 670 plugins that push the envelope of what's possible in the app. We want to continue to foster th

Show HN: We built a tool for fast-forwarding 95% of tests (MIT) https://ift.tt/LsCoUp8

Show HN: We built a tool for fast-forwarding 95% of tests (MIT) Hi, we're Yuval and Roey. We are working on a tool for speeding up test runs, by skipping tests unaffected by code changes. Effectivly, Saving 80-95% of the time, by skipping 80-95% of tests. We started a few months ago, and have managed to get into a few production CI systems here in Israel. All our prospects and users are on holiday right now. So we decided to repackage and open-source for local test running. available here ( https://ift.tt/l7tIMHP ) under MIT license. One line change: pytest -v -> nabaz test --cmdline "pytest -v" Stalk us on GitHub, or just Star us. Ask questions, we'll answer in under 30 seconds. we have auto refresh on. Yuval and Roey from Israel. https://ift.tt/l7tIMHP October 13, 2022 at 03:23AM

Show HN: Cobalt – social media downloader with no bullshit https://ift.tt/xAvjqBG

Show HN: Cobalt – social media downloader with no bullshit Hey, HN! I made my own social media downloader because I got annoyed by others that either shove 50 ad banners down your throat, or require you to do some extra steps. The frontend page is light and all processing is done on the server, so it runs speedily on pretty much anything. It also has a bunch of download/ui customization options, but none of them are forced on you. My main goal was to make something that's open, easy to use, and not annoying to deal with. Please take a look at it and let me know what you think, I'm thirsty for feedback and opinions. You can also take a look at its source code and judge my coding abilities: https://ift.tt/cVeCqnJ https://co.wukko.me/ October 12, 2022 at 10:33AM

Show HN: Turn any YouTube video into a website/transcript https://ift.tt/Ieg2y0V

Show HN: Turn any YouTube video into a website/transcript Hey HN, ExpoReader is a viewer for YouTube videos that shows the transcript of the video, and generates a shareable URL for a completely readable version of a video. I built it because I wanted helpful tutorials without having to watch an entire video. In a later version, I was thinking it could be cool to show other screenshots from the video throughout the transcript, but there’s really no easy way to do that outside of downloading the video and taking clips from there. If anyone has any good suggestions, I’m all ears! https://ift.tt/GuI2zA1 October 12, 2022 at 02:42AM

Show HN: InvokeAI, an open source Stable Diffusion toolkit and WebUI https://ift.tt/TJ89Zix

Show HN: InvokeAI, an open source Stable Diffusion toolkit and WebUI Hey everyone! Excited to be able to share the release of `InvokeAI 2.0 - A Stable Diffusion Toolkit`, an open source project that aims to provide both enthusiasts and professionals a suite of robust image creation tools. Optimized for efficiency, InvokeAI needs only ~3.5GB of VRAM to generate a 512x768 image (and less for smaller images), and is compatible with Windows/Linux/Mac (M1 & M2). InvokeAI was one of the earliest forks off of the core CompVis repo (formerly lstein/stable-diffusion), and recently evolved into a full-fledged community driven and open source stable diffusion toolkit titled InvokeAI. The new version of the tool introduces an entirely new WebUI Front-end with a Desktop mode, and an optimized back-end server that can be interacted with via CLI or extended with your own fork. This version of the app improves in-app workflows leveraging GFPGAN and Codeformer for face restoration, and RealESRGAN u

Show HN: A.I. Runner with Stable Diffusion https://ift.tt/En97YXK

Show HN: A.I. Runner with Stable Diffusion Hi, I have been here a few times showing off tools that I have created for Stable Diffusion. This is my latest creation, A.I. Runner. It is an application which allows you to run Stable Diffusion locally. It runs on GPU or CPU (slower), allows you to watch the images generate in real-time, offers a NSFW checkbox, and installs all requirements including the model. You can also go from cold start to generating images in seconds. I have many more features in the works including the ability to run more models (thus the more generic branding). https://ift.tt/9Lu0ACk October 10, 2022 at 11:15AM

Show HN: Related Website Finder Experiment Thingy https://ift.tt/bh6ALfP

Show HN: Related Website Finder Experiment Thingy Been messing with cosine similarity and decided to try calculating nearest neighbors over the entire link graph for the marginalia search engine. Turns out that you can just bruteforce that in a day or two. And the results are pretty good. One drawback is that depending on if you're looking at an older website, a lot of the links are dead. The deduplication isn't great either. https://ift.tt/197SEyq October 9, 2022 at 11:22PM

Show HN: Simplepdf.eu – a browser-based PDF annotator / editor Hi HN! I've been working on SimplePDF to solve a problem I encounter weekly: filling out non-editable PDFs [1] --- # About SimplePDF - The documents you load, edit, fill never see the light of my server, everything is processed locally – no remote uploading anything. This includes the PDF generation. - There are no analytics / third party tracking your every move (I do collect usage data, but it's fully anonymous and processed and stored on my server): therefore no annoying cookie banner. You can read more on the Privacy Policy [2] - If someone before you has filled the same document, upon opening it you'll see fields already set, ready to be filled-in, think crowd-sourced fields positioning – saving you time and effort. --- # How does the crowd-sourced positioning of fields work? When a document is loaded in your browser, a fingerprint of the document binary is made, and sent to the server. The document table c

Show HN: BlockTalk – Banter about what your friends are doing on Web3 https://ift.tt/FrpJI2R

Show HN: BlockTalk – Banter about what your friends are doing on Web3 Hey HN, I’m Kamil and one of the two people working on BlockTalk. BlockTalk is going into public beta today! (We're also on Product Hunt, come check us out!) We previously posted about this project under the name “WalletWatch” in a Show HN about 3 weeks ago, and have since integrated your feedback to make it better [1] [problem] As we were trying to see how our friends were using crypto, we noticed that other products were either too complex or only let us passively view what our friends were doing. [solution] BlockTalk is a social network centered around Ethereum transactions. You can easily see, understand, like, and comment on the Ethereum transactions of anyone on the platform. We don’t ask for your email or password, and instead authenticate by asking users to sign a transaction with their Ethereum wallet; we ask for usernames to give a more familiar and user-friendly experience for people that haven’t purch

Show HN: Building a Git teaching tool that runs Git in the browser Repo: https://ift.tt/jtPGenA Harmony was born as a tool to create and/or modify local files, on the fly, in your browser. Few weeks ago I decided to try to implement a sort of version control system in it. I think it would be cool one day to either use it for personal use or to teach Git concepts in a sandboxed area. Harmony is powered by web assembly and it runs all the git related stuff in-memory. In this release I brought an initial support for directories and the possibility to checkout to a particular commit https://ift.tt/YL48QNC October 9, 2022 at 07:40PM
