Show HN: Mercury – Publish Jupyter Notebook as web app by adding YAML header https://ift.tt/3H6ahE0

Show HN: Mercury – Publish Jupyter Notebook as web app by adding YAML header Mercury is a perfect tool to share your Python notebooks with non-programmers. - You can turn your notebook into web app. - You can add interactive widgets to your notebook by defining the YAML header. Your users can change the input and execute the notebook. - You can hide your code to not scare your (non-coding) collaborators. - Users can interact with notebook and save they results. - You can share notebook as a web app with multiple users - they don't overwrite original notebook. The demo running at Heroku (free dyno) https://ift.tt/3Itu1Sx , at AWS EC2 (t3a.small) https://ift.tt/3Ar66k0 - No need to register. https://ift.tt/3qogDsx January 20, 2022 at 05:26PM

Show HN: Hacker XP – Hacker News styled as a Windows XP Outlook email client https://ift.tt/3IsEqOd

Show HN: Hacker XP – Hacker News styled as a Windows XP Outlook email client Hello HN, sharing my weekend project. I'm a fan of retro GUIs and fan of HN, so I built an alternative HN front end that resembles a Window XP desktop with an old Outlook email client. Archive and github links if you get 500 errors: https://ift.tt/3fKUiPY.... https://ift.tt/3IsJKkD https://hackerxp.com/ January 23, 2022 at 12:58AM

Show HN: Pianobar-remote-control – low-frills go web remote for pianobar https://ift.tt/3GRMDLJ

Show HN: Pianobar-remote-control – low-frills go web remote for pianobar I like to play pianobar on a bluetooth speaker but don't always want to walk over to my desk to hit next, so I made a terse little web remote in go. Now I just whip it open in my phone. Took about 3 hours and then another 1.5 later to polish it up for sharing. 'twas a fun little project that someone else might enjoy using. Looks like in retrospect there are some pretty feature-full pianobar-web repos out there, but certainly none as simple/short. https://ift.tt/3tSZ2Lx January 22, 2022 at 08:38AM

Show HN: qme: simple utility for queueing long-running commands https://ift.tt/3Am2sHP

Show HN: qme: simple utility for queueing long-running commands I keep needing a way to run long-running resource intensive tasks after one another. 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 22, 2022 at 04:31AM

Show HN: Loadjitsu – a modern load testing alternative to JMeter https://ift.tt/3GPspSM

Show HN: Loadjitsu – a modern load testing alternative to JMeter Please meet Loadjitsu, my weekend project, years in the making. Over the years while building different apps and sites, I always felt that I need a modern load testing software.Tools like JMeter, ab are not very easy to use and it seems innovation in load testing which is a crucial part of any software release cycle has been ignored. This is my third attempt at making Loadjitsu, I am so glad that I can finaly release this. A bit more about the software 1. 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. Lets you load test databases like MySQL, PostgreSQL, Mongodb out of the box. 4. Will keep adding more load testing targets in the future (even the more esoteric ones) I hope to open source Loadjitsu soon and let users contribute new targets. Hope this makes load testing fun agai

Show HN: Get latest replies to an HN user https://ift.tt/3rzlAOE

Show HN: Get latest replies to an HN user Hi HN, I hacked a simple service for gathering HN replies and organizing them by the parent's username. The main idea is to be able to efficiently get the latest replies to an HN user. For example, you can use this service to send yourself notifications when some replies to you on HN. The service queries the official HN API and can be self-hosted. It is basically ~30 lines of Bash script. I made this mostly for educational purposes -- thought you might find it useful for something. Cheers! Edit: for example, here are the latest replies to me [0]. It includes only recent replies, since I started the service just yesterday and it hasn't observed older replies. [0] https://ift.tt/33CZanN https://ift.tt/3IlE8Zn January 21, 2022 at 02:25AM

Show HN: Progress.org https://ift.tt/3fCCh6m

Show HN: Progress.org Progress.org must be one of the oldest sites on the Internet, and quite likely the oldest site that has continuously advocated for economic justice. A few years ago, I took it over and gave it a new facelift (thanks, Webflow!) So today, it’s my great pleasure to announce a next chapter for Progress.org Earlier today I transferred stewardship of Progress.org into the capable hands of Floyd Marinescu, a man whom I deeply respect and admire. Floyd is a successful entrepreneur and the founder of UBI Works (https://ubiworks.ca), Canada’s preeminent basic income advocacy organization. While basic income was the start of Floyd’s journey of economic discovery, his journey didn’t end there, but continued to develop once Floyd discovered the inequities created through our contemporary system of property ownership. His interests have grown to encompass the teachings of JM Keynes, Henry George, and other economic giants. In their spirit, he intends to continue Progress.org’s

Show HN: Stop Putting AWS Credentials in GitHub Secrets https://ift.tt/3FS5XXX

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! I'm Happy to take questions and comments here or on Gitter: https://ift.tt/3tEk7cE https://ift.tt/33Mas8S January 19, 2022 at 01:50AM

Show HN: A tool to help you manage technical debt https://ift.tt/3qzR3Ru

Show HN: A tool to help you manage technical debt Caribou helps software teams manage long-term technical migrations in their projects. For example migrating from one networking library to another or migrating a codebase from one architecture pattern to another. These changes usually happen over a span of a few months and without any tooling, they can be difficult to manage. It’s difficult to understand how much progress has been made, what is still left to do and who are the engineers helping move the migration forward. Caribou was built to solve these problems. So how does it work? In simple terms, Caribou is a Github application which, after being configured, monitors all the changes in your repository and displays a dashboard with the progress of specific migrations along with who is contributing to these migrations. Caribou allows you to define all sorts of migrations using an easy-to-use rules engine; for example changing the project architecture, replacing a library or changing

Show HN: Golang Cafe – Go Jobs Board – You Can Now Filter by Minimum Salary https://ift.tt/3Kn1aAX

Show HN: Golang Cafe – Go Jobs Board – You Can Now Filter by Minimum Salary Hi Everyone, I have been working on and off on Golang Cafe for a couple of years. Golang Cafe[0] is the first Go job board with no recruiters and clear salary ranges. Engineers apply directly to companies. There is always a developers section where you can submit your Go developer profile and get hired (for free)[1]. This weekend I have added a new feature. It's now possible to filter jobs by minimum compensation. So for example here's a list of all Go jobs paying at least $100,000+ a year[2]. The project is open source [3]. Any criticism is very welcome. [0] https://golang.cafe [1] https://ift.tt/3upWKBt [2] https://ift.tt/3rnY8UE [3] https://ift.tt/2NnnQVd January 18, 2022 at 12:45AM
