Testlemon is now Open Source – API Test Automation Tool

Hello everyone!

I’m excited to share that after 1.5 years of development, testlemon is now Open Source. All code for the engine, Docker image, MCP server, and GitHub Actions is publicly available in our repos here: https://github.com/testlemon

The SaaS app will still be available for paid users, with a free trial here: https://app.testlemon.com/

Testlemon helps you automate API testing. It supports testing response status codes, response time, and body content without coding. You can also do test chaining, manage variables and secrets, and—recently added—automatically generate tests from an OpenAPI specification.

Generate tests from OpenAPI spec example:

docker run --rm itbusina/testlemon -c https://api.apis.guru/v2/openapi.yaml

Run tests from a test collection:

docker run --rm itbusina/testlemon -c "$(<collection.yaml)"

You can find full details about test collections, validators, and integrations in the documentation: https://docs.testlemon.com/

Give it a try and let me know what you think! Feedback is super welcome.

Who owns freshcode.club, freshfoss, etc?

From what little I've been able to dig up, whomever owns freshcode.club (and others) has been running this on his/her own dime and it's just been sitting there, slightly neglected for a while. It's now down, and there's no more information.

Does anyone know who is running (at least) freshcode.club? I'd like to help fix it, or at least get an idea of what's going on.

Now more than ever, location sharing privacy is important.

Hey folks!

Our names are Chandler & Fatima and we've been working on an app called Grid (mygrid.app). We built it because we got tired of location sharing apps brazenly exploiting user location data (think Life360 and location sharing services selling user location data to data brokers, federal/gov agencies, etc.). We wanted a way to share location without having to compromise on our data privacy.

It's an open-source project that's fully self funded. Because it's meant to be a tool that helps the overall cause, we want to make sure it's the absolute best version it can be: the most useful, valuable and private version for users.

Here’s what Grid is:

Location sharing with end‑to‑end encryption (profile photos are also E2EE), using Matrix Synapse for the backend. Only people you choose to share with can see your location.
Self‑hosting options: you can run your own backend server and host your own map tiles. If you do this, you take on risk and maintenance.
Minimal data collected: phone number (for verification - we're working on alternatives/foregoing phone numbers altogether), username. No tracking, no location data stored in decrypted form by us.
Sharing features: 1:1 or with groups, shared durations/expiration, you control when to stop sharing.
Map tiles are by default Protomaps via Cloudflare; unless you self‑host, map tile fetching involves some metadata/logs by the map tile host (i.e. they can see what tiles were requested)
All core features will remain free. Cosmetic/nice to haves options will be paid (currently we have satellite maps) in order to continue to fund development and work on the project!
Points of Interest: Drop points on the map of locations that are of interest to your group (meet up points, restaurants, etc.)

Where Grid still has work to be done:

If you self‑host but mix with other Matrix use, there are warnings: Grid isn’t fully tested in federated settings. Could be bugs.
The phone number for verification: We're working to move away from this.
The map tiles’ privacy: Protomaps routed through cloudflare, some metadata/requests may leak. Looking into alternatives and offline maps.
UI, and edge case bugs need polish. It’s relatively smooth in performance, but not “mission‑critical proven” in every context. We're only a two-person team so our workload capacity is limited.

Here’s how people in the community are value added to the project:

Test it in real conditions and tell us where it fails.
Audit us. Grid isn’t built for the lowest common denominator but for security and privacy. Check our github out, help us identify where the gaps are so we can close them.
Ideas for improving self‑hosting security, map privacy, or making it usable on phones without Google services. We SO welcome contributions!

Let us know what you all think!!

Alien vs Predator Image Classification with ResNet50 | Complete Tutorial

I just published a complete step-by-step guide on building an Alien vs Predator image classifier using ResNet50 with TensorFlow.

ResNet50 is one of the most powerful architectures in deep learning, thanks to its residual connections that solve the vanishing gradient problem.

In this tutorial, I explain everything from scratch, with code breakdowns and visualizations so you can follow along.

How to analyze Git patch diffs on OSS projects to detect vulnerable function/method that were fixed?

I'm trying to build a small project for a hackathon, The goal is to build a full fledged application that can statically detect if a vulnerable function/method was used in a project, as in any open source project or any java related library, this vulnerable method is sourced from a CVE.

So, to do this im populating vulnerable signatures of a few hundred CVEs which include orgname.library.vulnmethod, I will then use call graph(soot) to know if an application actually called this specific vulnerable method.

This process is just a lookup of vulnerable signatures, but the hard part is populating those vulnerable methods especially in Java related CVEs, I'm manually going to each CVE's fixing commit on GitHub, comparing the vulnerable version and fixed version to pinpoint the exact vulnerable method(function) that was patched. You may ask that I already got the answer to my question, but sadly no.

A single OSS like Hadoop has over 300+ commits, 700+ files changed between a vulnerable version and a patched version, I cannot go over each commit to analyze, the goal is to find out which vulnerable method triggered that specific CVE in a vulnerable version by looking at patch diffs from GitHub.

My brain is just foggy and spinning like a screw at this point, any help or any suggestion to effectively look vulnerable methods that were fixed on a commit, is greatly appreciated and can help me win the hackathon, thank you for your time.

Browser automation using recorded user sessions

Hey Everyone! I created a tool that can record user sessions on a website and will convert them into playwright browser actions. The initial idea was to use this for QA, but I thought maybe this could be helpful for other browser automation use cases as well. Here's how it works:

1. Developer can add our js snippet to their html
2. It records clicks, fills and selects. This can be extended to more actions
3. User can generate automation workflows by leveraging the user sessions recorded and use AI to determine how to complete a task

Here's a video of how it works and my website. If people are interested, I can open-source the recorder -> playwright automation!

An opensource math competition website (still a WIP, but has functionality)

Hello,

I hope this is an OK place to post this: I am working on an opensource math competition site. It is called https://conjecscore.org/ and it currently only has 1 problem. But even though there is only one problem, the problem does not have a known solution. It's an open math problem. Instead of having a known solution it has a "score" function that determines how "close" you are to solving the problem (informally). It still has a lot of rough edges but I was wondering if people were frankly even interested in the idea. If so, I could try finding more open problems and give them a score function too. Additionally, I could continue polishing the site too. Lastly, and most importantly, the source code is here: https://github.com/thyrgle/conjecscore

Thank you for your time.

Thinking about open sourcing our POS system - looking for advice

Hey r/opensource!

I've grown up on open source and use it daily. Now I'm considering open sourcing **Biyo POS (https://biyopos.com)** \- our all-in-one point of sale system for restaurants/retail.

We currently serve hundreds of businesses with features like offline transactions, inventory management, online ordering, and multi-payment support list goes on..

**Why we're excited:** There's a real gap for a solid open source POS. Small businesses are stuck with expensive proprietary solutions or piecing together multiple tools. We actually provide it pretty much free if business process their payments for us - but, we want to grow more and provide more value especially as someone who came up in the retail industry.

**What we need advice on:**

* Anyone open sourced a commercial product before? Biggest wins/challenges?
* Best licensing approach for business software?
* How to balance community contributions with quality/security?
* Sustaining development while keeping it truly open?
* Should we release everything at once or start with core components?

We want to build a real community around this, not just dump code and run.

**Are we crazy or is there potential here?**

Thanks for any insights!

Open source in today’s world is mind boggling

I couldn’t and still can’t wrap my head around the fact that a person, with proper skills, would make something that would have a paid alternative or worked hard but instead of selling it or having a subnoscription, placed it on the internet, completely free or not, but allowing users to basically see it, use it, build it.

Someone putting their mind on the internet believing in the community and expecting nothing monetary back but rather to improve their product and see it go and some even pay out of pocket for that thing to keep running, is just crazy.

I understand not everything open source is free, but having it open source allows others to potentially use it for free or your property to be the community’s instead of yours alone, like blender and gimp and libreoffice who give a completely working and valid alternative to the multi million or maybe billion dollar companies’ products, or things like ublockorigin which could have easily been made with subnoscriptions like a lot of thing before it, or the millions of projects out there left in hopes to help the community in some way.

I’ve always had an aim, to build my experience to the point where I could contribute, because this is where I’d feel fulfilled enough to know I can help, but I just keep wondering, if you get nothing directly in return, why would you personally put your project, hard work and potential money machine to open source?
