GitHub Copilot and open source laundering

Filed under

We have seen an explosion in machine learning in the past decade, alongside an explosion in the popularity of free software. At the same time as FOSS has come to dominate software and found its place in almost all new software products, machine learning has increased dramatically in sophistication, facilitating more natural interactions between humans and computers. However, despite their parallel rise in computing, these two domains remain philosophically distant.

Though some audaciously-named companies might suggest otherwise, the machine learning space has enjoyed almost none of the freedoms forwarded by the free and open source software movement. Much of the actual code related to machine learning is publicly available, and there are many public access research papers available for anyone to read. However, the key to machine learning is access to a high-quality dataset and heaps of computing power to process that data, and these two resources are still kept under lock and key by almost all participants in the space.1

The essential barrier to entry for machine learning projects is overcoming these two problems, which are often very costly to secure. A high-quality, well tagged data set generally requires thousands of hours of labor to produce,2 a task which can potentially cost millions of dollars. Any approach which lowers this figure is thus very desirable, even if the cost is making ethical compromises. With Amazon, it takes the form of gig economy exploitation. With GitHub, it takes the form of disregarding the terms of free software licenses. In the process, they built a tool which facilitates the large-scale laundering of free software into non-free software by their customers, who GitHub offers plausible deniability through an inscrutable algorithm.

  • How to install Wireshark on Ubuntu 22.04 or 20.04 LTS - Linux Shout

    Use the default system repository to install Wireshark of Ubuntu 22.04 LTS Jammy Jellyfish or 20.04 focal fossa Linux distros.

    The Sniffer Wireshark is available in all Linux distributions to easily install. Apart from it, the executable can be downloaded for Windows and Mac OS. This open-source application is very useful for network administrators. IT can record the traffic, where you can look at the contents of a data packet. The IP address of the target system is always logged. Wireshark, for example, can be used to expose notoriously programs using networks to perform some unusual tasks. You can also statistically evaluate the collected data traffic, for example by searching for particularly large packets or picking out addresses that are frequently accessed. A counter-test of who owns such an IP address may then put you on the trail of an attack.

    Wireshark logs the network traffic of the interfaces of the system on which it is installed. It can therefore examine all incoming and outgoing connections of the respective computer. At the same time, it also receives all data packets that are sent to all systems in the network (broadcasts).

Mekotronics R58 review - Part 1: Rockchip RK3588 mini PC unboxing & teardown

Filed under

Mekotronics R58 is a cost-optimized Rockchip RK3588 mini PC and SBC that sells for as little as $169 with 4GB and 32GB eMMC flash. The company has now sent me a model with 8GB RAM and 64GB flash for evaluation, and in the first part of the review, I’ll do an unboxing, check out the hardware more closely, and boot it up for a quick check.

There’s no retail package so to speak with just a white box and a sticker reading “MINI 8+64G” indicating the RAM and storage capacity for the device.

The mini PC ships with a 12V/3A power adapter and cord, an IR remote control with two AAA batteries, two WiFi antennas, an HDMI cable, and a USB-A to USB-C cable probably to flash the firmware if needed.

I Made A Home Assistant Hub Using The Atomstack X20 Pro

Filed under

I’ve been slowly adding more and more devices and sensors to my home automation setup and it’s gotten to a stage where I now have a pretty significant number of apps to control them on my phone and iPad. I’ve also wanted to set up automations and routines between devices, but the interfacing across platforms and between brands isn’t usually available or is buggy at best.

If you’ve done anything home automation related on a Raspberry Pi then you’ve probably heard of Home Assistant. It a free and open-source software package that is designed to be a central hub or control system for all of your smart home devices and it’s got a pretty substantial online community working on integration. So, for example, it allows you to do things you wouldn’t normally be able to do like use an Ikea motion sensor to turn on a Philips hue light. Something that isn’t supported by either ecosystem individually.

So today I’m going to be installing Home Assistant onto a Raspberry Pi and I’m going to use a new laser cutter, the Atomstack X20 Pro, to laser cut a housing for it so that I can put it somewhere convenient in my house without it looking like a jumble of wires, dongles and PCBs.

Raspberry Pi 'Slimshader' Adds Real-Time Visual Effects to Your Music

Filed under

Custom synth projects are nothing new in the Raspberry Pi community but this open-source shader PCB known as Slimshader is definitely a breath of fresh air in the DIY synth world! Created by maker and developer Erik Oostveen, this project aims to provide custom visual effects to music in real-time.

According to Oostveen, Slimshader is a GlslViewer-based, open-source PCB designed to display shader files with a Eurorack design. It offers both analog and HDMI output for video, allowing users to add visual effects to music in real-time. If you’re new to shaders, these are graphic simulations that respond to audio input.

The Slimshader PCB was designed from scratch by Oostveen and features a graphics design printed across the top. It has a series of inputs available that can be used to program custom visual effects. On the reverse is a Raspberry Pi which powers the project. Slimshader has been tested and confirmed to operate with a Raspberry Pi Zero W, Raspberry Pi Zero 2 W, and a Raspberry Pi 3B.

A custom image file was created just for the Slimshader which, can be downloaded from a Google Drive link available on Oostveen’s website. Shaders can be displayed and modulated using audio input, potentiometers, low-frequency oscillators, voltage control and even via MIDI. Oostveen recommends glslsandbox for finding shaders to experiment with created by various artists who share their work online.

In just over a decade, ChromeOS has evolved into a massive ecosystem the like so of which, not even Sundar himself could have predicted. You may have heard someone say “a Chromebook is nothing more than a browser” and once upon a time, that would have been fairly accurate. Problem is, that synopsis has stuck around entirely too long and has created a stigma around ChromeOS that prevents many from even giving a Chromebook a chance.

  • This Week In Rust: This Week in Rust 448
  • Vetting the cargo

    Modern language environments make it easy to discover and incorporate externally written libraries into a program. These same mechanisms can also make it easy to inadvertently incorporate security vulnerabilities or overtly malicious code, which is rather less gratifying. The stream of resulting vulnerabilities seems like it will never end, and it afflicts relatively safe languages like Rust just as much as any other language. In an effort to avoid the embarrassment that comes with shipping vulnerabilities (or worse) by way of its dependencies, the Mozilla project has come up with a new supply-chain management tool known as "cargo vet".

  • Rethinking Fedora's Java packaging

    Linux distributors are famously averse to shipping packages with bundled libraries; they would rather ship a single version of each library to be shared by all packages that need it. Many upstream projects, instead, are fond of bundling (or "vendoring") libraries; this leads to tension that has been covered here numerous times in the past (examples: 1, 2 3, 4, 5, ...). The recent Fedora discussion on bundling libraries with its Java implementation would look like just another in a long series, but it also shines a light on the unique challenges of shipping Java in a fast-moving community distribution.

    As is often the case with Fedora, the conversation started with the announcement of a Fedora change proposal; this one is authored by Jiri Vanek. The proposal is aimed at the Fedora 37 release, which is currently planned for late October. Vanek proposes to change Fedora's builds of the OpenJDK Java development kit (JDK) to link against several of that project's bundled libraries (including zlib, FreeType, libjpeg, and HarfBuzz) rather than the versions packaged separately in Fedora. The JDK would also be statically linked against Fedora's build of the libstdc++ library.

    This proposal, however, is only the first step in a longer project to change how the JDK is built. In short, once the JDK (along with the Java runtime environment, or JRE) has been made to use its own libraries, the way these components are packaged will change. The RPM for a given JDK release will contain a single tarball that will be unpacked on the target system. Notably, this tarball will be the same for all Fedora releases, from the oldest supported release through Rawhide; the use of bundled libraries will help to ensure that this package will work the same way on all target distributions.
