I’m looking to follow more creators and developers on the Fediverse who are passionate about open-source, privacy-first software, and system tinkering.

I spend most of my time working within the Android development stack, building local-first/offline-first applications, running Arch Linux, and messing around with low-level Android rooting and custom kernels.

Let's follow each other!

Hello everyone, you may remember I dropped by a while back concerning my cooperative management project.

The idea has evolved to building an open-source Enterprise Resource Planning application specifically for worker's cooperatives. While most ERP software focuses on driving top-down directives, the goal of this project is to enable the cooperatives to work, make decisions, and resolve disputes more efficiently than basically any other type of company.

Current tech stack: Docker, postgres, nginx, SQLAlchemy, gunicorn, jinja2, Flask, Alembic, and Redis.

Please check out the repository documentation if this sounds like something you may be interested in. The docs include the foundational philosophy document called "Hierarchy by Consent" and there is also a template for an Articles of Incorporation that I intend to include as the first default document template in the software.

I'm still pretty early in the process but most of the tables are set up and I've made notes in the the classes explaining the requirements and workflows.

I've also got some issues started on Codeberg, mostly related to the front-end, which is where I need the most help at the moment. I will certainly be glad for help elsewhere as well.

It's an open-source project so there is no immediate financial incentive. Part time contributors are certainly welcome.

There's a discussion room on Matrix and here is the Repository.

Thanks folks

I never see in public git projects something like a declaration of scope. There's also no convention, unlike a README.md (which rarely contains some sort of scope definition) or LICENSE file.

Is this unusual in open source projects, that you first define what you want and not want in your project and how you want to do it, to combat scope creep and sabotaging yourself?

I'm in a postition in live (short of a burnout) where it's actively a pain to just start things and then wing it; i even add a scope comment to larger shell scripts.
Maybe it's experience, because i already know that i'm then not satisfied afterward or (in case of shell scripts) just create a unfinished mess. Nobody else?

Hello lemmings, I made a program to ping every IPv4 address and collect data on respondents. I am almost done, but I want feedback on things I should change or how I can improve my current record of 5,000 pings / second.

I am currently aware that I need to properly parse the data I receive on the receive socket, since it's possible the TTL router messages might be confused as replies. ICMP is used on networks to inform other machines of network problems.

One issue I'm aware of is the tuning that has to go into maximizing throughput while also avoiding a total system freeze. My code seems to spend too much time opening sockets that it leaves no room for the actual OS. My only fix currently is limiting the CPU time to the ping timeout I used.

The overall program works like this: It keeps a linked list / pool of task objects. All objects are initially in the "free list" and then when they become associated with a socket, they move to the "active list". The program first checks for updated sockets with epoll which results in like 5% of sockets giving a response. It then closes any tasks that have timed out via linked list in O(1) each. The slow part is when it creates new sockets, since it doesn't really know when to stop, besides when the non-blocking socket informs it that it would block. I implemented a time limit on sending that is currently the maximum of the ping timeout. To increase throughput it seems like I need to streamline how I send ICMP packets.

I recently decided to ditch my ancient WordPress portfolio and build a new site from scratch.

Because I wanted to show off a little bit, I decided I wanted to make it into a 2D side-scroller using Little.js. The issue was figuring out how I could keep the site accessible.

I just wrote the first blog post in a series on how I am making that very site.
The site is still a work in progress; but I felt this could interest people here. And it gives me a chance to test out the blog feature I just coded in.

I wrote a blog post about me getting in to FSharp web application development, but am having issues deciding how I want the data access to look. I'm very much open to feedback!

The Khronos OpenCL Working Group has released OpenCL 3.1, bringing widely deployed, field-proven capabilities into the core specification to expand functionality, including SPIR-V ingestion, that developers will be able to rely on across conformant implementations.

Features now mandated by OpenCL 3.1 have been deployed as extensions or optional capabilities. This is by design. The OpenCL working group evolves the specification by proving features in the field as extensions first, watching how they get used across multiple implementations, refining them based on developer feedback, and only then graduating them into the core specification.

Every conformant OpenCL 3.1 implementation will be required to consume SPIR-V kernels — a feature that has been one of the most requested by developers. OpenCL 3.1 additionally requires support for the SPIR-V query extension, which enables applications to enumerate the SPIR-V capabilities, extensions, and versions that a device supports, simplifying the adoption of new SPIR-V features as they become available.

Several features essential to HPC and AI kernels are also now mandatory in the core OpenCL 3.1 specification:

• Subgroups, including shuffles, rotations, and an expanded set of supported data types. A fundamental building block for tuned reductions, scans, and matrix kernels.
• Integer dot products, including saturating and accumulating variants, together with extended bit operations: Both map directly to dedicated hardware instructions on a wide range of modern silicon, and both are common building blocks for matrix multiplications and the low-precision arithmetic central to inference workloads.
• A new query for the suggested local work-group size. This gives applications and profilers a runtime hint for the optimal work-group size for a given kernel and device, eliminating the need for manual tuning or repeated size calculations across multiple enqueues and improving performance predictability on diverse hardware.
• A standard device UUID query, matching Vulkan’s VkPhysicalDeviceIDProperties::deviceUUID. This allows applications to correlate the same physical device across APIs, which is essential for multi-device systems and for external memory-sharing scenarios that span OpenCL and Vulkan.

wares is available on GitHub. Looking for anyone willing to test, provide feedback, or even contribute

Ever seen our AOSP based apps (Phone,Messages,Gallery...) & thought I could make a difference to bring them up?

We're seeking a senior Android engineer to take ownership of the default app suite:

Code standard is high, vibe coders need not apply.

You may have noticed that activity on the public Log4cxx, Log4j, and Log4net repositories has slowed since December 2025. I want to reassure you that the projects are still being actively monitored...

Companies are replacing entry-level coding positions with AI tools, creating a dangerous gap in the talent pipeline. If no one trains the next generation of developers, who will maintain and build the systems of the future?

TL;DR: The big tech AI company LLMs have gobbled up all of our data, but the damage they have done to open source and free culture communities are particularly insidious. By taking advantage of those who share freely, they destroy the bargain that made free software spread like wildfire.

When publishing a package for use by programmers, automated changelog generation is very beneficial. In this blog post, I explore how to do it in a simple way that works everywhere.

Hi, this is a post for you to rant on your sore points on technology

See I am trying to think of a good project idea one that people actually want solved, is there an app you wished existed, a site u wanted, put it down here and hey what do you know you may just see an ad in some while that now it exists
