Show HN: KnifeGeek – Online Database of Pocket Knives
2 by ICodeSometimes | 0 comments on Hacker News.
Hey HN! About a year ago i stumbled upon the world of swords, knives, and EDC gear. A weirdly addicting (and expensive) hobby to have. Back then i noticed something, it was quite tedious to easily sift and search through knives based on length, steel, brand, and what not to find the knife for me. There were some great youtube channels that helped me pick out what i wanted however i had to sit through multiple 30 minute videos just to review 10-15 knives or so each. Recently i've been having a little trouble sleeping so i decided to pickup a new passion project to work on late at night, here's KnifeGeek! it's a completely free website where you can search, filter, and sift through an extensive knife database (over 60K+ knives) and add them to your collection or wishlist. You do need to sign in to add stuff to your wishlist or collection and after a bunch of advanced searches. Please check it out and let me know if you think anything is missing! I'll try to flesh it out more on a daily basis if people find it cool or useful. Planning to add in price comparison functionality and more data per knife in the next week. PS: Images are a little shoddy, working on that.

Show HN: TunnlTo – Windows WireGuard split tunnel client built with Rust, Tauri
3 by brndnbuilds | 0 comments on Hacker News.
Hi Everyone, TunnlTo is a tool for controlling which Windows applications, processes, and IP addresses can use a WireGuard VPN tunnel. Here are some examples of how it could be used: - Route only FireFox through a privacy VPN - Route Slack and Microsoft Office through a work VPN - Route a game through a gaming VPN - Stop a game from routing through a privacy VPN - Stop a browser from routing through a work VPN - Route a specific IP address range through a privacy VPN - Route all traffic through a privacy VPN except a specific IP address range I have been collaborating on this project with the creator of WireSock - Vadim Smirnov. "WireSock VPN Client is a lightweight command line WireGuard VPN client for Windows that has advanced features not available in the official WireGuard for Windows such as selective application tunneling and disallowed IP addresses. WireSock VPN Client combines the power of Windows Packet Filter and BoringTun (user space WireGuard implementation in Rust) to provide exceptional performance, security and scalability." The TunnlTo app is built with Tauri and I've used boring old HTML, CSS (bootstrap) and JavaScript as I had major JS framework fatigue. I have previously built a production app with Electron and Vue. Tauri appealed to me for its use of Rust and its small installation sizes. I tried Tauri pre version 1.0 and had a bit of trouble but this time around its been a positive experience. The docs and the Discord community have come a long way. I would appreciate any feedback about the project so I can get an idea of what direction to take it in next. Vadim will be around a little later if anyone is curious about the WireGuard implementation and wants to know more. Thanks for reading!

Show HN: Diarycli
2 by Aperocky | 0 comments on Hacker News.
Having had good usage and some positive feedback on https://ift.tt/vK3uEMN , I decided to pack it into a pip package. Essentially, all this does is to make creating diary super simple in the CLI, and resulting diary organized in a nice /diary/year/month/date.md hierarchy. Having used this for a few years, I find this tool indispensable - I was never able to write diary consistently but once it was available via `diary` it became nature to utilize this to manage daily tasks at work and write personal reflections at home.

Show HN: I got unlimited airport WiFi access
2 by xkcd1963 | 1 comments on Hacker News.
Most airports offer wifi in following variants: #1 unlimited free wifi access #2 time-limited free wifi e.g. 2 hours, after this one has to pay #3 pay upfront for wifi I happen to be in a #2 airport and figured that by changing my MAC address I should be able to circumvent the artificial limitation by the airport through knowing my initial MAC address. On my macbook though the commands ```sudo ifconfig en1 ether 00:e2:e3:e4:e5:e6``` don't seem to work after the year 2018 (thank you apple). After some search though I was able to change the MAC address https://ift.tt/wsnXJ0y and enjoy now unlimited wifi while waiting for the airplane.

Show HN: Clamshell- an experimental Python based shell
10 by benrutter | 2 comments on Hacker News.
About a month ago I started a suprisingly-not-that tricky project to build an experimental python repl that I could use instead of bash as a daily shell in windows, mac or linux. It"s more hack-for-exploration than a production ready shell, but here it is! Hope somebody finds it anywhere near as interesting to check out as I found making it. Disclaimer: I know about xonsh and love it (if you haven't heard of it, google it). This project is more pure python and less python and bash interacting - see the readme for more details.

Show HN: Peer Review Beta – GitHub plus StackExchange for Scholarly Publishing
4 by dbingham | 0 comments on Hacker News.
Hi HN, I've had the idea for a scholarly publishing site that could crowdsource the work of the journals using concepts borrowed from Github and StackExchange and recombined for years. I finally got enough runway to take about 6 months off of work to build it. This is the result. It's still in beta, but the core MVP features - review, reputation, responses - are all there. I'm sure there are as yet to be found bugs, because I'm on my own and I've always been terrible at testing my own stuff. Right now it's best treated as non-archival pre-prints with review. I'm starting my next full time role on Monday, so I'll be carrying it forward as a side project. I'm going to continue working on it, albeit more slowly and on nights and weekends. It's open source and with an open roadmap, and I would welcome collaborators. I would love and appreciate any thoughts and feedback!

Show HN: Knotend – a keyboard-driven flowchart editor
2 by escot | 2 comments on Hacker News.
Hey all, I made knotend [0] because I wanted a flowchart editor that was keyboard-driven and super fast. I was tired of dragging boxes around on a canvas. You may have seen knotend around here before when I wrote an initial blog post [1] about why I wanted a new kind of flowchart editor. Thank you to everyone who has given me feedback here on HN! Since that blog post I’ve been working hard to get to a v1 which I’m showing now. You can use the free version without having to sign up for an account. I would love your feedback! What makes knotend different is two main things: 1) The nodes are constrained to a grid which enables a keyboard-centric experience for selection and navigation, and 2) there’s autolayout so each time you add a node, the graph automatically lays itself out and places each node in a cell. In the future I’ll be working on supporting more complex editing actions, linking graphs together, collaboration, and more. Please drop your feedback below, reach out on twitter [2], or email scott@knotend.com. [0] https://www.knotend.com [1] https://ift.tt/sz7efCy [2] https://twitter.com/ScottyAntipa

Show HN: A GPT-driven tool for analyzing & tracking your resumes & job postings
3 by digitalgangsta | 1 comments on Hacker News.
Jobs-Scout is an AI (OpenAI's GPT) driven job tracking tool that can parse job postings and analyze your resumes against them. The AI recommends qualifications, accomplishments and keywords that can improve your chances in matching the job posting. As you add job postings to the tool, it allows you to set status, notes and track resumes used and be better organized as well. I'm keeping it free hoping it will be helpful to some of the new job seekers out there. All I ask for is any feedback that could improve it. PS. an email is needed to login. For Beta, you can use a fake email, but I may clean-up unverified users later. I promise that email goes nowhere other than for authentication.

Show HN: Automatisch – Open source workflow automation, an alternative to Zapier
17 by farukaydin | 0 comments on Hacker News.
Hey, HN community, We're so excited to share Automatisch with HN finally. Automatisch is an open-source workflow automation tool, an alternative to Zapier. Together with my co-founder (@barinali), we have been working on it for about 15 months and have started getting early adopters. Automatisch is a workflow automation tool that lets you connect different web services like Slack, Github, Twitter, and more to automate your business processes. For example, you can build automation that gets all new tweets, including the "open source" phrase, and post them to the Slack channel you specified. You can adjust the services and steps depending on what you actually need to automate in your business. Even though some existing cloud solutions do the job well enough, we still wanted to build an open-source and self-hosted alternative to those. Because it allows you to store your data on your own servers, which is essential for businesses that handle sensitive user information and cannot risk sharing it with external cloud services. This is especially relevant for industries such as healthcare and finance, as well as for European companies that must comply with the General Data Protection Regulation (GDPR). You can see the available integrations here ( https://ift.tt/7SeLjM6 ). We currently have limited integrations but are constantly working on adding more and enhancing the existing ones. You can also request a new integration by using GitHub discussions: ( https://ift.tt/jvLl21t... ). You can use the following links to check it out: Website: https://automatisch.io Docs: https://ift.tt/AeCwbv7 GitHub: https://ift.tt/4np8uR9 Please give it a try and let us know if you have any feedback, and if you like what we are doing with Automatisch, please give us a star on GitHub. Cheers!

Show HN: UpTrain – Open-source ML observability and refinement tool
38 by sourabh0394agr | 2 comments on Hacker News.
A couple of months ago, we left our jobs to build UpTrain AI, an open-source machine learning observability and refinement tool which helps users understand the performance of their models in production and improves them over time by identifying problematic data-points for retraining. Data drift, Distribution shifts, Model degradation, Edge cases - we have personally faced these problems in our previous organizations and have built a lot of tooling to solve them. We are building UpTrain so that others don’t need to build them and can solely focus on improving their ML models while we abstract away all the engineering complexities. You can get UpTrain for free by checking it out on GitHub ( https://ift.tt/x27eH1N - available under Apache 2.0 license). We're not trying to make money off individual developers, but we do have some enterprise features, a hosted version, and support that we charge for. Give it a try and let us know what you think!

Show HN: Create QuickBooks Sale Receipt from 3rd Party Transactions
3 by thedangler | 0 comments on Hacker News.
Hello everyone. I created a very niche product for my payment gateway customers. They are struggling with the manual process of marking transaction(s) as received in QuickBooks for their franchisor reports and bookkeeping. Paysync.ca turns a manual process into an almost fully automated solution by turning a transaction into a Sale Receipt. We currently support NMi gateways or affiliated gateways and soon importing CSV files. If you are interested you can join the beta program at https://paysync.ca Hacker News registrants will be granted access in front of the line. Have a good day!

Show HN: LowEndInsight – a “bus-factor” risk analysis tool
2 by kitplummer | 0 comments on Hacker News.
What began as a pet-project a few years back, an a start to learning functional programming with Elixir, turned into a bit of a research effort for CS students. I'd asked them what info could they glean from a git repository, specifically about the risks associated with using it (or becoming dependent on it). The focus quickly arrived at "bus factor" - what happens when the main developer moves on. From there we started thinking about other metrics and a couple stood out - mainly the distribution of contributions, and the obvious commit currency time. The initial research was focused on library packages from the main ecosystems - e.g., Javascript's NPM and Python's PyPI. We quickly found that to be a massive challenge - at the time neither required packages to provide a valid URL pointing to their source code. This itself was an indicator of something. Once the students moved on I continued to think about and would occasionally get asked about the tool. So I picked it back up and slapped an API on it and exposed it via HTTPS POST and GETs. I am generally looking for feedback. Probably more about the issues associated with dependence on Open Source libraries - the risks derived as software atrophy happens. But what are your ideas about the metainformation that is sitting in a software project's source history. I've considered doing some ML-y stuff with the commit history, but haven't really found the right things there yet. Here are some links to the details: * Library: https://ift.tt/txKAnS1 * API: https://ift.tt/r7NJifS... * API Source: https://ift.tt/FCha6lS * CLI: https://ift.tt/zePbSIO * CLI Source: https://ift.tt/ufpvKt5 * Demo - GitHub Trending Repos: https://ift.tt/VlI3hAX I've capped the number of requests at RapidAPI, but if you really think the tool is useful I can issue you freer, more unlimited access by request. Let me have it HN. And thanks in advance.

Show HN: Making an open source project regrouping the most interesting AI APIs
2 by samyai | 0 comments on Hacker News.
Hi, I'm working on a project that regroups all best AI (AIaaS) from different providers (GCP, AWS, Azure, DeepL, etc.) [in one API]( https://ift.tt/hCb67Jw ). I've got asked the question : *why aren't you regrouping Open Source models (instead of proprietary APIs) into one repo?* well because it doesn't make sens to deploy and maintain large pytorch (or other framework) AI models (especially for document parsing, image and video moderation or speech recognition) in every solution that wants AI capabilities. So using APIs makes way more sens. Deployed OpenSource models are being included using different APIs like HuggingFace and other equivalents. The current plan is to add some of these AI capabilities into [n8n automation]( https://ift.tt/OIg8rAD ) and [Odoo App]( https://ift.tt/Xu3JqDG ) (*receipt, resume* and *ID document parsing, content moderation* and *translation*) . Some other capabilities can include : *summarization, keyword extraction, sentiment analysis* for text data and also *speech to text* or *image* and *video tagging*. Do you know other Open Source projects You want this could integrate to ?

2 by sheganinans | 0 comments on Hacker News.
Hi all! So a few weeks ago I decided to write a low latency serializer. That meant being very careful about runtime costs and the size of the resulting byte array (packet fragmentation limits). I'm pretty happy with the result, it's based off the excellent Flat library on Hackage, and the benchmarks look pretty good. Looking forward to hearing your feedback!

Show HN: Linux and Windows CalDAV calendar client
2 by nibdo | 0 comments on Hacker News.
Hello, I have been developing self hosted CalDAV calendar Bloben (https://bloben.com), which is now available also as standalone Electron desktop client for Linux and Windows. It is using same client and server code base with some changes like: - switching from PostgreSQL database to SQLite - requests are handled with IPC - no account management, just single user Why Electron app when there is already self hosted client? I think there are some people, who don't want all features from self hosted version and using desktop app might be easier for them or it is just better alternative (be it maintenance, security, features). Published versions are advised to be for testing purposes only due to possibly many bugs. They can be found here: https://ift.tt/wuG0glc Main git repository is here: https://ift.tt/EZvTtq6 Thank you and feel free to try it or ask if you are interested in anything.

2 by markdotdev | 0 comments on Hacker News.
Hi HN, I thought some of you might find this useful/fun. cpwrap runs whatever command you pass it, sending the transcript to copilot and giving you autocomplete suggestions along the way. It's like how rlwrap gives you readline input editing- cpwrap gives you copilot input editing. In other words, copilot for ed: https://twitter.com/markdotdev/status/1616273277533446145 Or sh, python, any non-curses interactive shell program. And it's a single public domain c file, though you need node and the copilot extension files to run the copilot agent. (And a copilot subscription.)

Show HN: Dopt – State machines and SDKs/APIs for your user flows
6 by alonmower | 0 comments on Hacker News.
Hi everyone, Dopt lets you visually model flows (which are state machines) to power your product’s onboarding and education experiences. We offer a React SDK that lets you create instances of those flows for any user of your product and exposes methods for transitioning the state of the user—effectively moving them through the flow. Dopt then acts as a persistence layer for the users' flow state. Dopt lets you send in data about your users (identify calls/properties) and lets non-devs define rules based on that data for which users should enter the flows. Non-devs can also update content and other custom properties that can be referenced via the SDK. For example, with Dopt’s SDK you can build: - a multi-step, interactive product walkthrough that helps users learn how to use a product by using it https://ift.tt/gnGO20L - a getting started checklist that helps a team get setup and activated https://ift.tt/xMDwuo1 You can see a short 4 minute demo of how Dopt at https://www.youtube.com/watch?v=1gRvAp6Cnls We make iteration on your state modeling easy with flow versioning, and we even handle migrating your users between versions on the fly. Dopt's UI lets everyone easily track how users move through your flows and provides controls for enabling/disabling or resetting them. We’ll work right alongside your analytics and experimentation tools. We started Dopt because we’ve seen the teams building onboarding/education flows struggle with a similar set of issues that Dopt sets out to solve: - Homegrown onboarding is time-consuming to maintain (and it changes a lot!). The logic of the flows is complex and opaque to non-developers and devs are forced to be in the loop for every small copy, targeting, and logic change. - The customer and user data needed to show people relevant experiences lives in multiple places and is hard to build interactive experiences with (e.g. what’s their use case, what plan they’re on, what they’ve done in the product, what other teammates have done in the product, etc…). - Persisting and migrating user flow state is hard. The existing tools aimed at helping people put onboarding into their products frankly suck. They’re not built for developers, only offer boilerplate components, and have brittle integration points that are hard to troubleshoot. They end up producing mostly low-quality tooltip tours. We’re in a closed beta period right now but are looking to find more people building product onboarding and education that are willing to give Dopt a spin. We’re not charging for Dopt during our beta period and are just asking for feedback to help us learn how to make Dopt better. We’ll eventually start charging later this year (by monthly tracked users) when we go fully self-service but are planning on having a “free in-perpetuity” tier for small use cases to make it easy to evaluate whether Dopt’s valuable. We won’t pull the rug out from anyone who’s built with us during the closed beta. You can signup for our waitlist on https://dopt.com or drop us a note at info@dopt.com. If you mention HN we’ll skip you to the head of the line. We’d love any feedback on the site, docs, and examples too!

Show HN: ApyHub – API Utility Belt
4 by nikolasdimi | 2 comments on Hacker News.
Hi all, I am Samuel, founder of ApyHub. ApyHub is a Developer API “utility belt”, providing developers with powerful APIs that provide standard data and essential functionalities for every software application. @nikolas and I have spent the last decade working with engineering teams to build and operate SaaS products. What we observed was that our teams spent a lot of energy building small units of functionality that were needed to provide more complex business capabilities. Take for example the HTML to PDF conversion (which in turn was used to generate pdf invoices) functionality, or simple file conversions. Not to mention data related services like fetching country lists, time zones, and other services, like validating VAT, emails etc. This approach led to a lot of effort building and supporting all sorts of capabilities, instead of building what our business actually needed. Even though we used a lot of existing libraries, the work required to integrate and then support on production was significant. To address this problem, we started using utilities offered as a service. We did some R&D and found service providers that offered currency exchange rates, or PDF conversions as a service. This did indeed relieve some of the pressure, but it resulted in different problems: - Dealing with multiple subscriptions, with several providers that only offered one or two specific capabilities - Each of the providers had a specific way to integrate, such as different response standards, different authentication schemes and some did not fit right into our architectural pattern - On the compliance side, this approach led to data handling and management related questions from security auditors Seeing that there was no one who was really trying to solve the problem space that we identified, we started ApyHub. :) What we offer is a growing catalog of software utility APIs that can be consumed as a service by applications. That way, we aim to relieve developers from having to build the capabilities and maintain these utilities, but also reduce the integration efforts - by having uniform integration requirements: REST APIs, JSON payloads and outputs. Users can send inputs either as URLs or files, and they can access output files directly or get a URL to access them. We want to make it easier for developers to integrate our APIs into their applications without breaking their design standards (e.g by not downloading and re-uploading the files). All utility APIs can be accessed through the tokens / credentials that the developers generate for their application. We are launching with +35 utility APIs and are planning to grow this number in the near future. Adding more data utilities is one of our next key goals. Over time, we also want to extend and build more sophistication in terms of building workflows, bundling options and other features that will add more sophistication in the way software utilities are discovered, managed and consumed. Some of our APIs : -Apy Extract : Text from Webpage: https://ift.tt/Zz8cE9F -Apy Generate: Webpage Screenshot: https://ift.tt/0zNsKcU -Apy Image Processor : Resize : https://ift.tt/SAl65fD -Apy Generation : iCal : https://ift.tt/dYlQc6t We have a free tier, including up to 2M API requests every month. We are running a special offer for the HN community. Everyone who signs up with the APYHACKER code, will get 500K extra requests. If you are a developer, we welcome you to try our APIs. We have a free tier + the ability to generate personal tokens that can be used in your local environment for experimentation and testing. If you need help with anything, if you want to hang out, talk about your projects or share your insights, feel free to join our discord server. Cheers, Samuel and Nikolas

Show HN: Codex – Find and Replace for Code
3 by gushogg-blake | 0 comments on Hacker News.
Most editors' find & replace features are still very close to the original design intended for text documents, so they become unwieldy when you need to match across newlines and indentation for example, or when a parse of the code is necessary to capture a particular expression. Codex is an attempt to rethink what find & replace should look like in a modern code editor. It defines a simple but powerful syntax for describing code modifications, combining plain text, regular expressions and Tree-sitter queries, along with sensible handling of newlines and indentation*. It can be used just like regular plain text find & replace, but allows freely mixing in regexes and Tree-sitter queries as more flexibility is needed. It introduces "line quantifiers" for matching a bunch of lines at the same nesting level, so basic structural changes can be achieved without even using a query (see the JavaScript function example in the link). I designed Codex with a specific use-case in mind (the one I show in the video), so any suggestions for other things it should support would be much appreciated, as well as general feedback. *Indentation is relative and space/tab agnostic.

It defines a simple but powerful syntax for describing code modifications, combining plain text, regular expressions and Tree-sitter queries, along with sensible handling of newlines and indentation*. It can be used just like regular plain text find & replace, but allows freely mixing in regexes and Tree-sitter queries as more flexibility is needed. It introduces "line quantifiers" for matching a bunch of lines at the same nesting level, so basic structural changes can be achieved without even using a query (see the JavaScript function example in the link). I designed Codex with a specific use-case in mind (the one I show in the video), so any suggestions for other things it should support would be much appreciated, as well as general feedback. *Indentation is relative and space/tab agnostic.

Show HN: Columnar store for fast, lightweight logging
6 by tiwarinitish86 | 1 comments on Hacker News.
Founder here, Parseable is a lightweight log ingestion and query engine written in Rust. Parseable can ingest data from existing logging agents (FluentBit, LogStash, Vector, syslog-ng and more) using HTTP + JSON output. Ingested logs are stored as semi-indexed Parquet files (on disk or S3). You can query the data with builtin query engine using SQL or use a query engines of choice like Spark, Presto, Trino and so on. We also developed a Grafana data source plugin that lets you visualise log data via Grafana. Sample dashboard link in readme. As log data grew, our industry has responded with SaaS and fully managed offerings, but if you're looking for freedom, interoperability and full control over your data - there are no great options. With Parseable, we are looking to provide an strong, viable and FOSS alternative.

Show HN: A tool for motion-capturing 3D characters using a VR headset
25 by diegomacario | 3 comments on Hacker News.
Hi everyone! I'm one of the authors of this project. The demo you see here is powered by a tool that I recently helped develop and open-source at Shopify called handy. You can find the repo here: https://ift.tt/WK08I1P Most people don't realize that VR headsets have become really capable motion capture platforms, so we decided to release this tool to bring motion capture into the hands of everyone who owns a headset. With a cheap Quest 2 you can capture your hands using the headset's hand-tracking feature and your head. With an expensive Quest Pro you could capture your facial expressions using the headset's eye and face-tracking features. Thanks for checking this project out! I'm here to answer questions if you have any.

Show HN: Semantic Search for Confluence Workspace
2 by ayanb9440 | 0 comments on Hacker News.
Hello Hacker News! I built Sleuth, an open source search tool for your workspace. I originally started off with Slack but quickly learned that Confluence search is a well documented problem: https://twitter.com/beajammingh/status/1273742155731791872?s... Sleuth solves this problem using semantic search to find relevant Confluence pages and Slack messages for your query. You can ask Sleuth questions about HR policies, technical documentation, product decisions, and more. Sleuth is open source and can be self-hosted, although there are dependencies on OpenAI and Pinecone (which will be swapped out for open-source alternatives for larger orgs with regulatory constraints). Feel free to reach out in our Slack group if you're interested in using Sleuth in your workspace: https://ift.tt/Ukbsf5d... https://ift.tt/gRFAY27

If you follow soccer, you know that derbies are highly-charged matches between historically rival teams, usually local rivals. They are emotional and hard-fought matches that are great fun to watch, but while there are many online resources to find match schedules for different leagues, I could not find a resource with an always-updated list of upcoming derby matches. So I made one. Hope it's useful to you. Please let me know what you think.

Show HN: Cross-Platform GitHub Action
3 by JacobCarlborg | 0 comments on Hacker News.
I've created a GitHub Action for running commands on multiple platforms. This includes platforms that GitHub Actions don't natively support. It currently supports FreeBSD, OpenBSD and NetBSD. OpenBSD can run on x86-64 and ARM64, the other operating systems run on x86-64. Some of the features that are supported include: * Multiple operating system with one single action * Multiple versions of each operating system * Allows to use default shell or Bash shell * Low boot overhead * Fast execution * Runs on both macOS and Linux runners Compared to similar solutions like https://ift.tt/6ro1JUl , the boot time is around a fifth and the full execution time for the same job is around half of freebsd-vm (last time I tried). The readme contains more information about how it all works under the hood.

2 by andrewmurphyio | 0 comments on Hacker News.
As an engineer I get frustrated at other training courses that talk a lot of theory, but don't have a lot of practical advice and tools to actually help. So, I built an online self-paced training course on difficult conversations (think feedback, salary negotiation, etc) that I wanted to share with the community. I like to make my training courses more "algorithmic." A process you can follow to approach a Difficult Conversation, get in the right mindset to tackle it, and prepare what you need to that allows you to do it well. This course will teach you: - What Difficult Conversations are and what happens when you ignore them - Why having Difficult Conversations can be beneficial to you, your team, and your career - A framework (and accompanying worksheet) to help you prepare for Difficult Conversations

Show HN: Hlb-CIFAR10 0.2.0: New world record (~<12.38s) on single-GPU CIFAR10
2 by tysam_and | 0 comments on Hacker News.
Hello everyone, After recreating the accuracy/rough speed from David Page's implementation in hlb-CIFAR10 0.1.0 (18.1s on an A100, SXM4, Colab), it was down to some basic NVIDIA kernel profiling to figure out which operations were the long poles in the tent. Perhaps (somewhat?) unsurprisingly, the NCHW <-> NHWC thrash was the worst part, but unfortunately the GhostBatchNorm was a barrier even using the faster-on-Ampere channels_last memory format. A quick note before continuing -- some may find the use of a convolutional network and on CIFAR10 to be curious. A quick answer to that would be that in doing the research that optimizes well-known problems (especially if the testing path is incredibly rapid), we get much clearer pictures of what certain fundamental information learning limits are for systems like this, as well as stable prototypes that can then be translated (potentially somewhat analogously) into other modalities. You can see this practice with a few researchers, Hinton comes to mind though his work is much more fundamental and experimental than this is. Back to the release notes. Ultimately, however, we were able to get a similar level of regularization to the original GhostBatchNorm (called GhostNorm) in the code, which allowed us to remove it and a bunch of tensor allocation/contiguous tensor calls, saving us nearly exactly 5 seconds or so (!!!!). Replacing the call for nn.AdaptiveMaxPooling(1,1) with a torch.amax(dim=2,3), added an additional .5 seconds off the clock, bringing us down below Thomas Germer (@99991)'s excellently quick implementation of the same base method ( https://ift.tt/9OzbnKN ) and giving us the new world record. This work is pretty simple on its own -- though the various ways to use the nvidia profiler(s) can be very daunting to use and I can post snippets of the simplest way that I've found (via the torch.profiler route) if someone asks/is curious. That said, looking at kernel execution order and times can really and truly do a lot to quickly improve a network in conjunction with good research engineering practices. This is what I'm pretty good at doing so getting to flex a bit on a spare time project is fun. I'm consistently storing up time saves into a draft bin of sorts and plan on keeping releasing them in related/clustered releases as I'm able to appropriately polish them to whatever their capabilities seem to be. There is a lot of room to grow, and I think we now definitely have a good chance at making it within that 94% accuracy under ~<2s mark within a few years! This work is meant to be a living resume for me, feel free to check out my README.md for more info. I love a lot of aspects of the technical/nitty gritty side of the fusion of neural network engineering and the edge of research, particularly when it comes to speed, so this is my strong area. I'm certainly happy to answer whatever reasonable questions anyone might have, let me help with getting this project going for you (or other related stuff -- feel free to ask! <3 :)))) )

Show HN: Group accountability for atomic habits (iOS)
2 by junetic | 0 comments on Hacker News.
I started this project by running 10-day group challenges on Whatsapp. The group was gathered via a Webflow landing page, Google forms, Zapier and a PayPal button (here’s what I posted on HN at that time - https://ift.tt/nrzHuKM ). The WhatsApp challenges turned out to be a hit with over 85% checking in daily and 45% repaying to join multiple challenges. After having tried Streaks, Habitify, GTD, reminder apps, google calendar, Notion...etc—I was still having trouble staying consistent with my personal/wellness goals and habits. Methods from Atomic Habits by James Clear—are what worked best for me—but sticking to it alone was hard. For example, I had a daily push-up reminder on my google calendar that I ignored for almost a year. Fast forward, I’m now on day 120+ doing push-ups, meditation and waking up before 6am—after participating in group accountability challenges :) To see if we can scale it to help more people and potentially build a community-driven business—we just released an iOS app. Recap of how it works: - Join 10-30 day accountability challenges in small groups of 3-12 people - Commit a daily goal and check-in with the group on whether you didn’t or didn’t do it - Daily visual progress reports, reward credits/penalties and support from others helps everyone stay on track - Create and join private challenges with friends Would love to have you try it by joining a challenge—and see if could help you become the person you want be for 2023!

Show HN: RecoverPy 2.0: Recover deleted or overwritten files from your terminal
4 by pablolec | 2 comments on Hacker News.
Repo: https://ift.tt/viZfqax Hi! I just released RecoverPy version 2.0.0 and wanted to share it with you. RecoverPy is a tool with Terminal User Interface to recover deleted and/or overwritten data from your terminal. Version 1.0.0 was released probably around 2 years ago and I was quite amazed by how popular it got :) The initial audience was people trying to recover lost files, but it stuck with hacking/forensics community, I even got to receive mails to appear in hacking magazines and blogs. That was quite unanticipated but I'm glad it's useful to other people :) I got the idea when I was a noobie coder and, among other flaws, didn't use any VC. I worked all day long on a script when instead of outputting my script execution to a file I... output my log file content into my script file, then bam, my script was gone. I searched for solutions to recover it, the thing is it was not just "deleted", the file was still present, but its content has been overwritten. So after some research, I found it was possible to recover it with mostly a combination of grep and dd. RecoverPy is just that, it uses grep and dd under the hood and eases the whole process. So in the past few weeks (a few hours during past weekends) I worked on an entire TUI framework switch. Previously I used a dated, unmaintained Python TUI framework, finding a sexy and fresh one was quite difficult when I started the project :/ But months ago I saw the textual project and was amazed by the result. I was only waiting for some widgets to be available (I didn't want to reinvent to wheel) to jump into it. Textual is just amazing honestly and I can only recommend it if you need a Python TUI framework. I'd be happy to hear any feedback, issue, bug, etc. RecoverPy worked quite well on previous version, 1.5.2, the heavy rework may have introduced some new bugs. Furthermore, if you want to contribute you're also more than welcome! RecoverPy code is quite simple and textual TUI framework enables a modern asyncio workflow and I think, is a good playground if you want to step up.

(And yes technically not ChatGPT but as close that we can get with the APIs that are available.) I found this incredible useful for my work on Filestar. I wrote some instructions here on how to try this yourself: https://ift.tt/IHuqJ8t... Please let me know if you figure out any useful prompts.

Show HN: We’re building a gaming console for the browser
4 by kdzapp | 0 comments on Hacker News.
hey all, We’re excited to share bash.gg - a way to play all games on your browser. Our mission is to enable you to play games, from any device, with your friends. We're planning on using a combination of WebGL (soon WebGPU) & pixel streaming to run any game. Our product is going viral within a few school districts, here’s what we’ve built. The Problem: Poor Experiences: Mobile gaming is limited by hardware. Most mobile games are spammy & focused on optimizing value extraction. Existing web games are junk. Expensive: For good games, you need a console or PC, costing $600 - $3k. Not Scalable: Consoles are sold at a loss & desktop computers are too expensive. Necessary hardware is increasing in size and cost. On the other hand, games continue to get more computationally expensive. bash.gg: Great Experiences: We’re bringing the best games from PC and console to your browser so you can play from any device instantly. Affordable: You don’t need expensive hardware, just a stable internet connection. Scalable: As games demand more resources, they’re run in the cloud. The games that don’t need all that power can run in a browser. TLDR: Consoles make it difficult to play with all of your friends. If your friend has Xbox, and you have Playstation - you might not be able to play together. Having games on the browser lets anyone play, by just clicking a link. Not only that, but you can chat and play, all in one place. In progress features: pixel streaming (quic + webcodecs), community features, live audio/text chat (should release within in 2 weeks) Excited to hear what you all think!

Show HN: Tagging Assistant – add AWS cost allocation tags in your dev pipeline
16 by isemenov | 7 comments on Hacker News.
Hi HN! My name is Ilia. I'm here with my co-founders Thomas and Daniele to share our new feature, Tagging Assistant. AWS Cost Allocation Tags are labels on resources that attribute and track cloud costs. Tagging is a prerequisite to assigning cost ownership (e.g. by team/app/cost center) and creating cloud cost accountability. Tagging AWS resources is a manual process that’s done either when a resource is spun up or during a cost firefighting initiative to understand cost ownership. We figured there had to be a better way and set out to make tagging a seamless part of development pipelines that use GitHub and Terraform. Once set up, the Tagging Assistant GitHub action will allow you to continuously enforce and maintain your AWS tagging strategy within your Terraform projects. Each GitHub repository can be associated with a catalog key that maps to tag key-value pairs within the Tag Catalog on the Cloudthread App. Adding or changing tag key-value pairs in a Cloudthread’s Tag Catalog entry will generate a tagging update Pull Request each time the action runs, and fail if the appropriate tagging is not in place. An example of such an update is `.tf` build file getting `(locals {tags = …}})` added. All resources defined via Terraform in the repository will receive the same tags defined via the Tag Catalog. This is just the start – in the future we’ll create more tagging granularity so that it is possible to tag different provider aliases differently within a single project. A graphic showing how this works is here: https://ift.tt/mEInrl5 Tagging Assistant is free to use and instructions to set it up are in our docs below. https://ift.tt/T9B1Ntk By installing Tagging Assistant you’ll get access to the free version of Cloudthread’s cost visibility, savings insights, and unit economics features. Very excited to get feedback! Try it out, let us know what you think, and feel free to reach out directly to hey@cloudthread.io or by using the chat icon bottom right on the Cloudthread app.

Show HN: iMessage-exporter, a full-featured CLI app and library
2 by css | 0 comments on Hacker News.
I've spent a long time reverse engineering nearly every aspect of Apple's iMessage SQLite tables to build this program. As far as I know, there are no other tools that support the full corpus of iMessage features, including edited messages, app messages, reactions, and threads. I built this software to preserve some conversations with loved ones; I hope others find it useful as well. For the curious, here are some of the more interesting aspects of the database I came across: - Dates are stored as Unix timestamp with an epoch of 1/1/2001 00:00:00 - Messages can have multiple parts, denoted by some special invisible characters - Reactions are stored by prefixing the GUID of the reacted message with the index of the message part [0]. - URL messages cache data in the table, which we can parse and display [1]. - Edited messages store the history message edits [2] (I wanted to try out DDD here, which was fun!).

Show HN: Tortoise TTS as an at-cost open-source pay-per-second API
3 by vatsalaggarwal | 0 comments on Hacker News.
Tortoise TTS is the best TTS available today. We built an open-source, at cost, pay per second API for it. The quality of intonation it generates is unparalleled, and we hope our at-cost API will make it easier for people to build on top! This allows folks to run via a single API call - it costs $0.03/query. The WAV file is downloadable, we apply no restrictions. We're open-sourcing all our work — we made Tortoise run 30% faster, and have more improvements coming. If you're keen to contribute we can help with ideas, pointers, compute and data; just DM us. Our fork with the improvements can be found at https://ift.tt/ZPrsWHv . The deployment code can be found at https://ift.tt/Wv6XbJQ . There are already great alternatives for using : i) @mdnest_r's awesome Huggingface Spaces, ii) original Google Colab, iii) host it yourself. Our work should accelerate those who need an API, don't want to spend time/$ hosting and need a scalable infra backing them. We're especially excited about combining text-to-speech with content generated from LLMs, and about how it fits into video creation tools. Tortoise in its current form is also inaccessible to non-technical users, which is why we are also providing a simple UI on top (also "at-cost"): https://tts.themetavoice.xyz To use, generate an API key on https://tts.themetavoice.xyz and call via POST request. Or use the web UI. Or run your own deployment.

Show HN: I asked ChatGPT to convert a Chrome ext to a Firefox ext
2 by soheil | 3 comments on Hacker News.
I told it to create a virtual machine first: I want you to act as a Linux terminal. I will type commands and you will reply with what the terminal should show. I want you to only reply with the terminal output inside one unique code block, and nothing else. Do no write explanations. Do not type commands unless I instruct you to do so. When I need to tell you something in English I will do so by putting text inside curly brackets {like this}. My first command is pwd. Then I told it to create a python script to do the conversion: {Create and write to the filesystem a python script called convert.py that takes a URL as its first argument. The URL is a chrome extension. The script then converts the extension to a Firefox extension and saves the result in a directory called "res". Make sure the script works with an actual URL to a chrome extension on the Chrome Webstore. It requires you to possibly download the extension first from the URL. Also make sure the generated Firefox extension meets all the requirements and the Chrome to Firefox conversion takes place for all assets in the extension, it includes the content scripts, etc. Only print done to the terminal here when finished.} Then ran it with this URL (URL to Google Translate Chrome ext): python convert.py "https://ift.tt/ymJdA32" It actually created a zipped Firefox extension with the manifest file converted correctly, etc.

Show HN: A 100% free and interactive Python course for coding beginners
41 by alexmojaki | 3 comments on Hacker News.
Some highlights: - 100% free and open source ( https://ift.tt/h3FyI1i ), no ads or paid content. - No account required at any point. You can start instantly. (You can create an account if you want to save your progress online and across devices. Your email is only used for password resets) - 3 integrated debuggers can be started with one click to show what your code is doing in different ways. - Enhanced tracebacks make errors easy to understand. - Useful for anyone: You can have the above without having to look at the course. IDE mode ( https://ift.tt/VZHSXiO ) gives you an instant scratchpad to write and debug code similar to repl.it. - Completely interactive course: run code at every step which is checked automatically, keeping you engaged and learning by doing. - Every exercise has many small optional hints to give you just the information you need to figure it out and no more. - When the hints run out and you're still stuck, there are 2 ways to gradually reveal a solution so you can still apply your mind and make progress. - Advice for common mistakes: customised linting for beginners and exercise-specific checks to keep you on track. - Construct a question that will be well-received on sites like StackOverflow: https://ift.tt/qPVUgJA - Also available in French ( https://ift.tt/nDSEQAK ), Tamil ( https://ift.tt/boSfOtT ), and Spanish ( https://ift.tt/PYAqDdo ). Note that these translations are slightly behind the English version, so the sites themselves are too as a result. If you're interested, help with translation would be greatly appreciated! Translation to Chinese and Portuguese is also half complete, and any other languages are welcome. - Runs in the browser using Pyodide ( https://pyodide.org/ ). No servers. Stores user data in firebase. - Progressive Web App (PWA) that can be installed from the browser and used offline. ----------- A frequent question is how does futurecoder compare to Codecademy? Codeacademy has some drawbacks: - No interactive shell/REPL/console - No debuggers - Basic error tracebacks not suitable for beginners - No stdin, i.e. no input() so you can't write interactive programs, and no pdb. - No gradual guidance when you're stuck. You can get one big hint, then the full solution in one go. This is not effective for learners having difficulty. - Still on Python 3.6 (futurecoder is on 3.10) I am obviously biased, but I truly believe futurecoder is the best resource for adult beginners. The focus on debugging tools, improved error messages, and hints empowers learners to tackle carefully balanced challenges. The experience of learning feels totally different from other courses, which is why I claim that if someone wants to start learning how to code, futurecoder is the best recommendation you can make.

24 by NetOpWibby | 6 comments on Hacker News.
Seems like every time there's a negative Stripe story on here, the inevitable question, "any alternatives?" gets asked. Hell, I was tempted to ask myself. Instead, I decided to search hn.algolia.com to see for myself what others have recommended in the past. Might as well share the list with y'all, make it meta. -- 2Checkout | https://ift.tt/u9Y6m7I Adyen | https://www.adyen.com Amazon Pay | https://pay.amazon.com Authorize.net | https://ift.tt/mwd6tUq Balance | https://ift.tt/NnZLxP1 Braintree | https://ift.tt/zbqo2d3 ChargeBee | https://ift.tt/TeqUdAk Chargify | https://ift.tt/DXWAE2g Checkout.com | https://ift.tt/ekSVBIu DigitalRiver | https://ift.tt/jtvXHym Dwolla | https://www.dwolla.com FastSpring | https://fastspring.com GoCardless | https://gocardless.com MangoPay | https://ift.tt/hqtndjK Mollie | https://www.mollie.com Opayo (previously SagePay) | https://www.opayo.co.uk Paddle | https://www.paddle.com Payoneer | https://ift.tt/t1dabU6 PayPal | https://www.paypal.com Qonto | https://qonto.com/en Spreedly | https://ift.tt/mv4LYdw Square | https://squareup.com Verifone | https://ift.tt/sxp08Sz White | https://ift.tt/HhoejsJ -- Observations from my data collection: Sassy appears to have been acquired by FastSpring. Balanced Payments apparently went under but I found another payment service called "Balance" instead. Paymill is defunct but their Github org has a bunch of code. No idea what happened to Spryng Payments but Spryng still exists. It's also worth mentioning that a true "Stripe alternative" simply does not exist. No one does everything they do and I'm pretty sure most services are lacking in the developer documentation department. Still, having options is always great.

Might as well share the list with y'all, make it meta. -- 2Checkout | https://ift.tt/u9Y6m7I Adyen | https://www.adyen.com Amazon Pay | https://pay.amazon.com Authorize.net | https://ift.tt/mwd6tUq Balance | https://ift.tt/NnZLxP1 Braintree | https://ift.tt/zbqo2d3 ChargeBee | https://ift.tt/TeqUdAk Chargify | https://ift.tt/DXWAE2g Checkout.com | https://ift.tt/ekSVBIu DigitalRiver | https://ift.tt/jtvXHym Dwolla | https://www.dwolla.com FastSpring | https://fastspring.com GoCardless | https://gocardless.com MangoPay | https://ift.tt/hqtndjK Mollie | https://www.mollie.com Opayo (previously SagePay) | https://www.opayo.co.uk Paddle | https://www.paddle.com Payoneer | https://ift.tt/t1dabU6 PayPal | https://www.paypal.com Qonto | https://qonto.com/en Spreedly | https://ift.tt/mv4LYdw Square | https://squareup.com Verifone | https://ift.tt/sxp08Sz White | https://ift.tt/HhoejsJ -- Observations from my data collection: Sassy appears to have been acquired by FastSpring. Balanced Payments apparently went under but I found another payment service called "Balance" instead. Paymill is defunct but their Github org has a bunch of code. No idea what happened to Spryng Payments but Spryng still exists. It's also worth mentioning that a true "Stripe alternative" simply does not exist. No one does everything they do and I'm pretty sure most services are lacking in the developer documentation department. Still, having options is always great.

Show HN: I spent 2 years building Tablane as a 17-year-old
3 by marconlp | 0 comments on Hacker News.
Hi HN community, I'm Marcus, a 17-year-old Software Engineer from Germany. For the past two years I've been working on Tablane [0]( https://ift.tt/TN7D15A ) a task/project management tool, with features like: - Collaborative Editing (google docs) - Optimistic updates with RTK Query - Realtime sync with Socket.io - An awesome design Let me know what you think! Ask me anything! How I got here: 2020: I was developing a TTT [1] (Trouble in Terrorist Town) plugin for my minecraft server, when I started to require a project management tool to keep track of the features I wanted to implement, originally I used a text file, but after some time I started using products like ClickUp and Monday. But not long after I hit several paywalls for features that I wanted to use (Custom Status, Limited Number of Boards, ...) Soon after Tablane (originally task-board) was born. I started building the website using plain HTML, then found out about React and completed Colt Steele's "Web Developer Bootcamp" [2] and "The Modern React Bootcamp" [3] and started re-writing Tablane in React, and started adding feature after feature. Now I am about to finish Highschool and originally I thought about applying to college and spending another 3-5 years there, but after the positive feedback I got on a three month internship I did at ContentPepper, and seeing how my own projects developed, I decided to look for open Developer positions, to work with a team of experienced developers so I can learn even faster.

Show HN: Track and share your technical interview prep progress
5 by knightron0 | 0 comments on Hacker News.
A few friends and I just launched a web app to help people prepare for technical SWE/SDE internship interviews! We want to make it easier for people to prepare for interviews, especially for some of the largest tech companies. Core features include easy progress tracking, one-click link sharing, company-specific lists, and topic & difficulty-wise problem filtering. The problem list isn’t exhaustive and we are still looking for more open-source data to make our list more extensive. We want to hear about the bugs you find as this is the beta version. If you have any improvements to suggest, we are all ears! Our code is also completely open-source! Check out the repository here: https://ift.tt/BVOS7R3 Check out our ProductHunt launch here: https://ift.tt/otVwn2i

Show HN: Ello (YC W20) – AI-reading tutor for kids that works with real books
4 by tomsayer | 0 comments on Hacker News.
Hi HN, We’re Elizabeth, Catalin, and Tom - the founders of Ello ( https://ift.tt/M7KUFtY ). Ello is an AI-powered app that mimics the one-on-one interaction of a reading tutor by listening to, encouraging, and coaching kids grade K-3 as they read out loud from a real book. We posted on HN back in 2020 when we launched Trustle, a company designed to pair families with dedicated experts in child development. We learned from that experience that parents don’t want a consultant, but they do want actual help with specific challenges—one of the biggest being reading. Prior to COVID, 65% of 4th graders in the U.S. were reading behind level. The most recent National Assessment of Educational Progress report revealed that reading levels have dropped even further, to the lowest level since 1992. These disheartening statistics reinforce something we learned during our time at Trustle—of all the pain points parents face in raising children, reading can often be one of the most critical yet most difficult to address, especially if the child doesn’t like to read. In an effort to help reverse this trend, we used advances in speech recognition - driven by self-supervised learning - to create a virtual experience designed to provide effective reading support. It's no substitute for attention and coaching from a caring adult, which is obviously what kids really need, but unfortunately that is not always available. If every child had consistent access to 1:1 reading support and every parent or caregiver had the time, language skills, and confidence to help their children learn to read with no outside assistance, then there would not be a need for a technical solution. Unfortunately, we know not every child has this access, and many parents are looking for extra support. That's why we've built Ello. If you look at a great teacher or parent working with a child, they are talking to each other. Ello uses a speech recognition model that listens to what a child is saying and provides the appropriate phonics based coaching, as well as commentary and help. As a child reads across the page of a physical book, the Ello app tracks the child’s progress and picks up when they miss a word or get a word wrong and then steps in just like a good reading coach would. One criticism that we’ve heard since launching is that we are trying to replace the sacred role of a parent teaching their child to read. We say, “Not at all!”. Ello can serve as a resource for every type of parent without being a “replacement”, which is impossible in any case. We’ve had most success with children who are reluctant readers. Ello provides a fun environment to practice reading without the pressure of an adult watching you. We’ve seen kids who flat out refuse to read start to enjoy reading in a short period of time. We are highly privacy oriented; unlike most apps relying on speech tracking we can work completely on device with no internet and no audio data shared back with us. We launched in early in 2022 and have come a long way since then. The model works like this: we mail customers five books and a prepaid return shipping label every month. At the end of the month you mail the books back or keep as many as you want for an additional $5 apiece, and then we mail you next month’s box. Our reading specialists help determine the appropriate reading level for every child and make sure that we are sending books to match. Right now we support roughly K through 3rd grade, although Ello can be effective for some Pre-K kids as well. We know there are many parents on HN, including those with young children. We would love to hear about your experiences and needs around your children’s reading journeys and your perspective on how something like Ello might help. Or, if you’re in the US, give us a try - you can get a free month with code ellohacker. And of course we welcome any feedback, questions, and ideas! Elizabeth, Tom & Catalin
