Show HN: I build a terminal-friendly static file server https://ift.tt/dvI1bk8

Show HN: I build a terminal-friendly static file server If you ask why there was .hg and .hgignore in a Git repository, it's because I completely forgot this project is my first ever project using Mercurial as SCM. As such, I foolishly `git init` the repository and have to update both .gitignore and .hgignore to finish the changes. You can also see the Mercurial version of this thing at here: https://ift.tt/4wqgAQp https://ift.tt/A3TdLXP September 24, 2022 at 03:45PM

Show HN: An AI image generator for blog posts https://ift.tt/T3DVeKL

Show HN: An AI image generator for blog posts Hi there, I see many bloggers use stock images for their blog posts (as featured images or as in-post images). I thought of something and started trying to use AI to replace those images. I built a small tool for this so others can also test it out. It takes text content (ideally, the blog post intro in case of a featured image or the text content about whatever you want the image about) and gives you an image. It works for me but I am still testing this. How about you guys? https://ift.tt/WNIDRie September 23, 2022 at 05:21PM

Show HN: A Stable Diffusion desktop frontend with inpainting, img2img and more https://ift.tt/sfpzw0A

Show HN: A Stable Diffusion desktop frontend with inpainting, img2img and more I was frustrated with laggy notebook stable diffusion demos. Plus they usually didn't have all the features I wanted (for example some of them only had inpainting and some only had img2img, so if I wanted both I had to repeatedly copy images between notebooks). So I made this desktop frontend which has much smoother performance than notebook alternatives and integrates image generation, inpainting and img2img into the same workflow. See a video demo here: https://ift.tt/zelNsGB... Features include: * Can run locally or connect to a google colab server * Ability to erase * Ability to paint custom colors into the image. It is useful both for img2img (you can sketch a rough prototype and reimagine it into something nice) and inpainting (for example, you can paint a pixel red and it forces Stable Diffusion to put something red in there) * Infinite undo/redo * You can import your other images into a scratch p...

Show HN: An async traceroute(1) implementation in Rust https://ift.tt/WnSuYwM

Show HN: An async traceroute(1) implementation in Rust I wrote a minimal traceroute(1) clone that leans on asynchrony to reduce the time spent tracing a route. Underneath, it uses ICMP to do its job. The plan is to add support for UDP tracing and a path maximum transmission unit discovery mechanism. Comments and suggestions are welcome! https://ift.tt/wqOjyFN September 23, 2022 at 12:52PM

Show HN: Venice – open-source Plaid to Postgres in minutes without code https://ift.tt/M8QrZg6

Show HN: Venice – open-source Plaid to Postgres in minutes without code Hi HN! Tony & Ali here, we are super excited to introduce Venice - an open source financial data integrations platform. Our MVP is getting financial data from Plaid into your postgres database in under 5 mins. We met while building our own respective fintechs. We noticed how much developer time went into setting up and maintaining the infrastructure rather than actually building the fintech itself. In Tony’s last project Alka for instance, the engineering team spent 30%+ of time building and maintaining the data connectivity and pipeline rather than the core work of accounting. What we wish existed is a Segment / Airtable for fintech, letting you get financial data from wherever they are produced to anywhere they are useful. We think the most basic version is a Plaid to Postgres database connector with a self-service portal where your customers can add / remove / repair and manage their financial connections. T...

Show HN: Copy link to highlight alternative for Chrome with multiple highlights https://ift.tt/G4jWtPc

Show HN: Copy link to highlight alternative for Chrome with multiple highlights Hi HN! I made a Chrome extension called Save Link to Highlight. It makes it easy to share multiple highlights on a page without any hassles. It uses the same built-in technology in Chrome as Copy link to highlight. So, the link you share will highlight text on a page in most browsers without 3rd party tools. Ex. https://ift.tt/WKe8ovC It's free! No account or signup needed. Some everyday use cases • Share an article with a friend that also has the parts you found most interesting highlighted. • A teacher can share key points they highlighted for students on a Wikipedia page. https://ift.tt/HfX6b0M September 22, 2022 at 06:34PM

Show HN: Hurl, test APIs with plain text and libcurl https://ift.tt/mD0sHiw

Show HN: Hurl, test APIs with plain text and libcurl Hi, We're happy to release a new version of Hurl [1]. Hurl is a command line tool powered by curl, that runs HTTP requests defined in a simple plain text format: # Get home: GET https://example.org HTTP/1.1 200 [Captures] csrf_token: xpath "string(//meta[@name='_csrf_token']/@content)" # Do login! POST https://ift.tt/C0cJptv X-CSRF-TOKEN: HTTP/1.1 302 Hurl can be used to get data like curl, or as an integration testing tool for JSON/XML HTTP apis / HTML content. Requests can be chained, and one can add asserts on response headers, cookies and body. For instance: GET https://ift.tt/naFj7Nk screencapability: low HTTP/1.1 200 [Asserts] jsonpath "$.validated" == true jsonpath "$.userInfo.lastName" == "Herbert" jsonpath "$.hasDevice" == false jsonpath "$.links" count == 12 jsonpath "$.order" matches /^order-\d{8}$/ You can see more samples in the documentati...

Show HN: TaskTXT, plain text task-timing notepad https://ift.tt/qR70KSO

Show HN: TaskTXT, plain text task-timing notepad I built TaskTXT.com based on my experience timing my tasks. I found that committing to a task before I start helps with my focus, and guessing how long it will take, then timing it prevents me from wanting to give in to distractions because I'm "on the clock". Video Overview: https://www.youtube.com/watch?v=HOYO0c_D6w0 There's also a Mac app which you can download here: https://ift.tt/cRAKN9k Video overview of the Mac app: https://www.youtube.com/watch?v=qMs-V5v5gZY But I didn't want the tool to be distracting, so its based on plain text. That means the UI is very familiar and you can use it for generic notes in any structure you like. When you work in TaskTXT you are working directly on its data format, I made a video about this concept here: https://www.youtube.com/watch?v=kZdBgVZn5NI I think this tool is uniquely suited for programmers, so I'd be interested to hear any feedback about the product, or its viabi...

Show HN: iq – jq for images (using rust, LALRPOP) https://ift.tt/0sqpS4E

Show HN: iq – jq for images (using rust, LALRPOP) I wanted to share an experimental side project I have been working on for some time. I constantly use commands like `jq` and `yq` for processing structured data in my day job and I was curious if a similar idea could be applied to images. Another goal of mine was to get some exposure to with rust. I discovered the LALRPOP parser generator which really helped moved the project along ( https://ift.tt/s6dEy51 ) https://ift.tt/2ZHsuUV September 18, 2022 at 11:58PM

Show HN: Krita Stable Diffusion Plugin https://ift.tt/olzhCMF

Show HN: Krita Stable Diffusion Plugin This is still a very new project under active development but I wanted to show it off in case anyone is interested in bookmarking it or contributing. Demo here: https://www.youtube.com/watch?v=maWR7dDf4SE Although it will be improving, the codebase has a few issues The Good - ability to multitask within krita while generating images - uses a queue so you can queue up multiple images without waiting for your other batches to come back - no need for a webserver (uses sockets to communicate) - clean code - active development (i want to use this tool myself) - uses stablediffusiond and stablediffusion as separate repos, these can be swapped out as desired with some hacking The Bad - currently relies on rabbitmq and doesn't provide another option - plugin only does txt2txt. img2img works but is disabled - must acquire the model manually The ugly - not all of the features work yet. in fact you can only generate an image. - installation is somewhat i...

Show HN: A Search Engine for the Tildeverse https://ift.tt/KFtm7OA

Show HN: A Search Engine for the Tildeverse The tildeverse is the name for a loose community of public access unix systems inspired by Paul Ford's famous tilde.club essay. These little communities are built up around shared access to a single unix system, utilizing its native multi-user properties almost as a retro social network. Over time, the communities have grown and folks published handmade pages that have the vibe of the early WWW days. I built a search engine to let everyone find things on this quirky part of of the net. Enjoy! https://tilde.wtf September 16, 2022 at 07:38PM

Show HN: Aperture Open Source Flow Control and Reliability Platform https://ift.tt/fxQOhtU

Show HN: Aperture Open Source Flow Control and Reliability Platform Hello people of HN and fellow SREs! Over the past year, we have been building Aperture - an open-source flow control and reliability platform for cloud applications. Over the past few years, companies like LinkedIn[1], Google [2], Netflix [3], Stripe [4] have built cutting-edge flow control technologies to keep their applications reliable. Flow control is powerful because it enables graceful degradation- the ability to preserve key user experience pathways, even in the face of application failures. With Aperture project, we hope to democratize building reliable applications with effective flow control. Using Aperture’s powerful policy language, you can deploy flow control techniques such as weighted fair queuing for prioritized load-shedding and distributed rate-limiting for abuse prevention to your applications. Using modular components to build policies allows you to maintain optimal user experience during traffic sp...

Show HN: Rentaflop – Render your Blender projects without sacrificing quality https://ift.tt/gwW219U

Show HN: Rentaflop – Render your Blender projects without sacrificing quality Hi HN, My name is David Sokol, and I'm the founder of rentaflop (https://rentaflop.com). We're a crowdsourced render farm aimed at making Blender rendering fast and affordable. If you've used Blender, then I'm sure you've experienced the pain of waiting around for your animations to render. You've probably even had to sacrifice the quality of your work to reduce your render times. I've been there too. If you're like me, then you're also disappointed with the alternative solutions: spending thousands of dollars on graphics cards or using prohibitively expensive cloud render farms to get fast render times. Our solution to this dilemma is to leverage low opportunity cost hardware from around the world to allow Blender artists to render their projects quickly, affordably, and without compromising on quality. Since most graphics card owners aren't utilizing their hardware to...

Show HN: ViruSaas – Virus Checks as a Service https://ift.tt/4zNiw8s

Show HN: ViruSaas – Virus Checks as a Service Hi all, here is a side project I've just launched which might come in handy for certain situations. It's a very simple and free "do one thing and do it well" online service with exactly one feature: you upload a file, and it tells you — based on a ClamAV check — if that file contains a virus or not. I'm not having any ambitious plans with this project, but thanks to very low operational costs, I thought I can as well put it out there and keep it alive — maybe it's even useful for some people every now and then (just today, one of my coworkers forwarded me a fishy-looking email with an attachment, and using virusaas.com turned out to be the least painful way to do this kind of one-off check for a virus). I've also released the source code of the web app under GPLv3 at https://ift.tt/CyuZtao , although it's not as polished as it could be (no tests, for example — but see above, no ambitious plans). The main re...

Show HN: Mini Metroidvania in 13KB of JavaScript https://ift.tt/OzZmNAF

Show HN: Mini Metroidvania in 13KB of JavaScript As part of the annual JS13K games challenge, I've put together a pretty large (but small-in-code) Metroidvania game that fits in just 13KB of compressed Javascript. The source is available here: https://ift.tt/UR8DpwZ NOTE: the current head of the main branch is at 13.6KB due to quality of life patches. The legit 13KB version is tagged in github. Useful hacks: - Using Roadroller ( https://ift.tt/rnbivK1 ) for compression - Compressing the map data as grayscale PNG paired with some code generation. - Using procedural animation for all characters. - Replacing string enum with numeric enums for compression. - Built a small game engine for object lifecycle and rendering. - Single function to generate unique procedural songs for different regions. https://ift.tt/9wpYcHb September 14, 2022 at 12:25AM

Show HN: Stripe-quality API client libraries with a single button click https://ift.tt/ibOBuSz

Show HN: Stripe-quality API client libraries with a single button click TL;DR- Libninja will generate world-class client libraries for you, without you needing to fiddle with openapi-generator, maintain build pipelines, and so forth. If you just want Rust, reach out, and I'll create your client library at no cost, because I want to help Rust's ecosystem grow. -- Hi HN, I got into Rust in a big way about 9 months ago. While the language is quickly maturing, one large gap in the ecosystem is immature or non-existent client libraries for common API services like Plaid, Stripe, Twilio, Github, Slack, and so on. The existing openapi-generator templates create Rust libraries that don't even compile out of the box, so I started down the rabbit hole of creating a Rust-based toolchain to generate Rust client libraries based on an OpenAPI spec. Rust is an incredible language to build codegen tools in, because of algebraic data types, Rust macro system, and Rust's incredibly power...

Show HN: Quake VR – Quake (1996) as a first-class PCVR experience https://ift.tt/PjH5psQ

Show HN: Quake VR – Quake (1996) as a first-class PCVR experience Hello HN! I am proud to show you Quake VR, a "labor of love" one-man project that I started back in 2020 with the goal of turning Quake -- the timeless classic from 1996 -- into a first-class PCVR experience. --- > What do you mean by "first-class"? There are many mods out there that enable older games to be played in VR, however, not much thought is put into VR-unique mechanics or in making the experience feel seamless. While I do enjoy reliving nostalgic classics in VR (and thank the modders for their efforts), it does feel weird having to use a keyboard+mouse setup for a VR game, or -- even with motion controls -- not being able to physically interact with the game's world, or having a gun glued to one of my hands. With Quake VR, I tried my best to make the game feel like an experienced designed from the ground up for VR. A video is worth a thousand words: https://www.youtube.com/watch?v=MBo...

Show HN: We're building a search engine for GCP https://ift.tt/0nNXYjd

Show HN: We're building a search engine for GCP Hi HN, I previously wore SWE/SRE hats on GCP. Later, I was on the other side, managing thousands of machines. The friction points of onboarding and operating cloud systems are personal problems to me. I’ve found it hard to keep track of all the random cloud resources floating around, especially as my team’s assets proliferated. Occasionally, there is a resource affecting an outage but no one remembers where it is. I am constantly frustrated by existing tooling. APIs can work, after you’ve navigated the byzantine documentation, but I often find myself doing ad-hoc tasks which are best served by a UI. Unfortunately, the search bar in the GCP web console does not behave as you expect. For example, it only seems to search for prefixes, rather than substrings, on App Engine stuff. The GCP web console as a whole is boatloads of JavaScripts, 90+ navigation items on the left menu, and a constant stream of UX/UI controls. I'm fond of Hacke...

Show HN: Visualizing Startup Management with Timeline https://ift.tt/QVq0ZXK

Show HN: Visualizing Startup Management with Timeline Hi everyone, We are building a web app for startup founders. Like Jira, Notion, or ClickUp, we support task management. However, we think time is more important than the tasks, because startups need to build product fast, and shift focus fast. Therefore, we built one universal timeline to help you easily manage tasks, clients, projects and deadlines, so you can directly compare the important dates from all your departments and find one which matter the most now. We also support task auto scheduling, so when you shift your team to a new direction, you just need to change the priority, and we help you reschedule all the tasks in you team. So you don't need to manually updating the start date or the end date fields in Jira, Notion, or ClickUp. You may have heard of Motion ( https://ift.tt/f8RFyYx ), which also supports task auto scheduling. Unlike it, our app focuses on serving the startup teams and innovation teams. So we also hav...
