You can detect cheers, applause, filler words, edit transcript to edit audio, create audiograms and export in different formats. We also have a chrome extension that transcribes any audio/video on the page you are on. After transcription you can follow along with the audio and read the transcribed text while the audio is playing. You can search for spoken content in a podcast or other audio/video content in your browser. There are some limitations, our product only works on Chrome and Firefox, we only support english for now and audio longer than an hour is not guaranteed to be transcribed (we will lift this limitation soon) links: https://revoldiv.com chrome extension: https://ift.tt/3rc8Kak... https://revoldiv.com/ January 28, 2022 at 03:02PM

Show HN: Load Testing with Playwright Hi HN fam! Hassy from Artillery (YC S21) here. Playwright got a lot of love on HN today [1] - rightfully so, it's an incredible project! - so I thought I'd resubmit [2] an open-source project that lets you run load tests with existing Playwright scripts. GitHub link: https://ift.tt/3Dc1HAX The basic motivation for creating the project is that load testing complex web apps is a real pain in the ass. It takes ages to build out test scripts for a non-trivial web app with traditional API-oriented tools. If you've ever had to do it, you know how frustrating it can be. So we thought, why not try load testing with real browsers instead? Especially if we can just reuse existing E2E testing scripts we already have? (based on Playwright of course!) Turns out it can work very well. Is load testing with real browsers expensive? Yes, sort of - relative to more traditional load testing. This project lets you max out developer productivity points at t

Nectr is a service that lets IT professionals easily create a free, sharable profile that accurately captures your skills, experience and availability. With this functionality "in the can", we're in midst of extending our service to let you create a genuine, uncontrived network of colleagues that you've actually worked with and who can accurately confirm your skills and experience. These confirmations will form the edges in our graph that comprise your first degree network. As a long time freelancer, I started working on Nectr to fill a requirement that I've long had: ditching my Word-formatted résumé for good—and automatically answering the oft-asked question: "Are you available?". Existing options (LinkedIn, StackOverflow, JSON resume, etc.) just don't fit the bill. How is Nectr different than the alternatives? - Your profile (example here:

Internally, you might have Greenhouse with all the stages, interview notes, files, invites, etc but the candidate and recruiter still coordinate everything via email tag.

For the past year and a half, I've been working on building a better way. MockRocket makes it easy to show off your app, right from your web browser–no experience required. Choose a template, drag and drop a screenshot or video and display it on a realistic 3D device model. You can even animate it to create a video. You can customize as much or as little as you want, and export in up to 4K resolution. All rendering is done in the browser, not on a server–using WebGL and WebAssembly–so your imported designs stay 100% private. This is the first release! Please let me know if you have any feedback or questions! https://mockrocket.io January 26, 2022 at 07:11AM

Show HN: Infracost (YC W21) – open-source cloud cost policies Hi, we’re Ali, Hassan and Alistair, co-founders of Infracost ( https://ift.tt/3pZI5dK ). Infracost shows engineers the cost of each Terraform change in CI/CD before resources are launched. When something changes, it posts a comment with the cloud cost impact. e.g. you’ve added 2 instances and volumes, and have changed an instance type from medium to large, this will increase your bill by 25% next month from $1000 to $1250 per month. We launched the first version of Infracost just under a year ago ( https://ift.tt/2LvVsTX ). As we said in our first release ‘the people who are purchasing cloud resources are not shown costs upfront, so they don’t know how much the resources will cost before launching them’. Our assumption was that because we are open source and the engineers are flying blind, they would pull us into the workflow. Actually, something different is happening: The engineers are not pulling us in - it turns out to b

Show HN: Can code change our probation system? Hey HN, I made FinishProbation.com to help people who have to take UAs everyday. It's an app that helps people complete their probation sentence. The app will notify you when you need to take a drug test (supporting over 20 states) and includes a probation progression tracker. My first experience with probation was when I was eighteen. My best friend's life was turned upside down by his marijuana possession charge. This charge would not have been as severe in today's times, but the punishment ruined his educational future and his emotional stability. He felt that he was trapped in a disorganized cycle and it was hard for him to see the end. This would later drive me on a mission to code FinishProbation for offenders like my buddy who was overwhelmed by his probation sentence. To reduce the mental stress and toll that probation brings. And this is done by reducing the fear of missing a drug test with notifications, seeing the da

When you like your job and are excited about career growth, putting in extra hours can payout. But for some folks working enough hours and doing something on the side could be a better strategy. When you think of time as an investment, you may distribute it properly between a day job, side projects, and hobbies. How do you think of your time in the era of flexible work? Do you treat it as an investment, or do you go with a flow? P.S.

Normally, I'd write a script which loops over the items, but not knowing what needs to run (I pick files as I go through a folder), I knew it's time I create something to scratch my own itch. So, I've created this utility to queue up commands. It captures command, args, env and working directory and puts it in a queue, and runs it when it's time. At the same time, it spins up an RPC server to receive commands from other instances. If there's no server available, it becomes a server itself and waits for commands or shuts itself down after idling for some time. This is my first (published) Golang project, so guidance & review would be appreciated. https://ift.tt/3fMMi0O January 21, 2022 at 02:31PM

Powered by golang you can run load tests for tens of thousands of connections per second on very average hardware. 2. Cross platform, run it on Windows or Mac or host it on your linux machines 3.

It aims to have all the most important productivity tools (for companies) in one package. It will hopefully get more of those features in time, but currently there are already quite a few – tasks, docs, video meetings and so on. Why did I do it? Because I thought the current ones were not that good, and I'm talking about things like Microsoft's offering now. The different parts of their software were clumsy and they were not integrated very well into the whole – i.e. different parts were not designed in collaboration in mind. I realize it's quite a big app for one person to do, but let's just say that I felt I needed to do and finish it. Couldn't stop after I had started it. --- Here's an url you can try it without registering into it, and the usernames/passwords: https://piper.aamu.app/ username: richard ... password: richard1 use

The client is in nodejs https://ift.tt/3Fm8U3f , with an onchain server written in Rust https://ift.tt/3rs867f This package allows you to easily create options contracts for tokens on Solana, with specific expiry times and strike values on the blockchain in one line of code. Similarly, you can use it to mint tokens and create contracts on those tokens. This allows you to do things like mint an NFT for a piece of art and then sell a call contract to buy that NFT at a predefined price. Each contract is tied to an NFT too, so you can easily trade them as well. The onchain program is currently available on Solana devnet and testnet.

Show HN: Stop Putting AWS Credentials in GitHub Secrets Greetings! I've created a GitHub action that works that allows GitHub Actions to exchange a GitHub token for AWS Access Credentials. I've cultivated a few examples of it in action: https://ift.tt/3rt5qq6 I've always found management of AWS Credentials has been a pain. So this setting up this Action works like this: 1) A SAML Identity Provider is created in AWS 2) A Role in AWS is set up to trust that Identity Provider 3) A config file is added to the repository indicating which role can be assumed 4) The GitHub Action exchanges the Repo Secret for AWS Credentials using the SAML.to backend for the exchange Let me know what you think!

Show HN: Analog Project Board https://ift.tt/3IifCZs I don't see a lot of 3d models posted here, but I thought I'd share as it's related to IT / programming. Model description explains it, but basically, inspired by air track control boards (excuse me if i'm wrong here) where they manage flights and their details. Wanted a board I could glance at and see project specifics we're working on. Board holds 5 slats. Design the paper inserts for the slats how ever you'd like; jira #, trello #, whatever. Print the slats in whatever color works for you - red = critical, yellow is falling behind, white is going well, etc... January 18, 2022 at 03:43AM
