Winamp Source Code Will Be Opened Up, Company Says

Recently the company currently in charge of the Winamp media player – formerly Radionomy, now Llama Group – announced that it will be making the source code of the player ‘available to developers’. Although the peanut gallery immediately seemed to have jumped to the conclusion that this meant that the source would be made available to all on the announced 24 September 2024 date, reading between the lines of the press release gives a different impression.

First there is the sign-up form for ‘FreeLlama’ where interested developers can sign up, with a strong suggestion that only vetted developers will be able to look at the code, which may or may not be accompanied by any non-disclosure agreements. It would seem appropriate to be skeptical considering Winamp’s rocky history since AOL divested of it in 2013 with version 5.666 and its new owner Radionomy not doing much development on the software except for adding NFT and crypto/blockchain features in 2022. The subsequent Winamp online service doubled down on this.

Naturally it would be great to see Winamp become a flourishing OSS project for the two dozen of us who still use Winamp on a daily base, but the proof will be in the non-NFT pudding, as the saying goes.

Improved 3D Scanning Rig Adds Full-Sized Camera Support

There are plenty of reasons to pick up or build a 3D scanner. Modeling for animation or special effects, reverse engineering or designing various devices or products, and working with fabrics and clothing are all well within the wide range of uses for these tools. [Vojislav] built one a few years ago which used an array of cameras to capture 3D information but the Pi camera modules used in this build limited the capabilities of the scanner in some ways. [Vojislav]’s latest 3D scanner takes a completely different approach by using a single high-quality camera instead.

The new 3D scanner is built to carry a full-size DSLR camera, its lens, and a light. Much more similarly to how a 3D printer works, the platform moves the camera around the object in programmable steps for the desired 3D scan. The object being scanned sits on a rotating plate as well, allowing for the entire object to be scanned without needing to move the camera through a full 180° in two axes. The scanner can also be used for scanning more 2D objects while capturing information about texture, such as various textiles.

For anyone looking to reproduce something like this, [Vojislav] has made all of the plans for this build available on the project’s GitHub page including some sample gcode to demonstrate the intended use for the scanner. On the other hand, if you’re short the often large amount of funding required to get a DSLR camera, his older 3D scanner is still worth taking a look at as well.

Raspberry Pi Files Paperwork With The London Stock Exchange

If you’re a regular visitor to the Raspberry Pi website and you have a sharp eye, you may have noticed during the last few days a new link has appeared in their footer. Labelled “Investor relations“, it holds links to the documents filed with the London Stock Exchange of their intention to float. In other words, it’s confirmation of their upcoming share offering.

It has been interesting to watch the growth of Raspberry Pi over the last twelve years, from cottage industry producing a thousand boards in China, to dominating the SBC market and launching their own successful silicon. Without either a crystal ball or a window into Eben Upton’s mind, we’re as unreliable as anyone else when it comes to divining their future path. But since we’re guessing that it will involve ever more complex silicon with a raspberry logo, it’s obvious that the float will give them the investment springboard they need.

For those of us who have been around for a long time this isn’t the first company in our corner of the technology world we’ve seen burn brightly. It’s not even the first from Cambridge. Appointing ourselves as pundits though, we’d say that Raspberry Pi’s path to this point has been surprisingly understated, based upon the strength of its products rather than hype, and while Eben is undoubtedly a well-known figure, not based upon a cult of personality. There is already a significant ecosystem around Raspberry Pi, we’d like to think that this move will only strengthen it. We may not be looking at the British Microsoft, but we don’t think we’re looking at another Sinclair either.

This Week In Security: The Time Kernel.org Was Backdoored And Other Stories

Researchers at Eset have published a huge report on the Ebury malware/botnet (pdf), and one of the high profile targets of this campaign was part of the kernel.org infrastructure. So on one hand, this isn’t new news, as the initial infection happened back in 2011, and was reported then. On the other hand, according to the new Eset report, four kernel.org servers were infected, with two of them possibly compromised for as long as two years. That compromise apparently included credential stealing or password cracking.

The Ebury attackers seem to gain initial access through credential stuffing — a huge list of previously captured credentials are tried one at a time. However, once the malware has a foothold in the network, a combination of automated and manual steps are taken to move laterally. The most obvious is to grab any private SSH keys from that system, and try using them to access other machines on the local network. Ebury also replaces a system library that gets called as a part of sshd, libkeyutils.so. This puts it in a position to quietly capture credentials.

For a targeted attack against a more important target, the people behind Ebury seem to go hands-on-keyboard, using techniques like Man-in-the-Middle attacks against SSH logins on the local network using ARP spoofing. In this case, someone was doing something nasty.

And that doesn’t even start to cover the actual payload. That’s nasty too, hooking into Apache to sniff for usernames and passwords in HTTP/S traffic, redirecting links to malicious sites, and more. And of course, the boring things you might expect, like sending spam, mining for Bitcoin, etc. Ebury isn’t exactly easy to notice, either, since it includes a rootkit module that hooks into system functions to hide itself. Thankfully there are a couple of ways to get a clean shell to look for the malware, like using systemd-run or launching a local shell on the system console.

And the multi-million dollar question: Who was behind this? Sadly we don’t know. A single arrest was made in 2014, and recovered files implicated another Russian citizen, but the latest work indicates this was yet another stolen identity. The rest of the actors behind Ebury have gone to great lengths to remain behind the curtain.

The Alien Energy Crisis Solved

Since the dawn of the industrial revolution, humans have been searching for more energy. Especially lately, there has been a huge interest in wind, solar, geothermal, and other ways to capture and harness power. However, we have a huge power plant just eight light minutes away: our sun. Oh sure, we toy with solar power, but the amount of sunlight hitting the Earth or even Earth orbit is a tiny fraction of Sol’s total output. But what if you could capture nearly all of the sun’s output? Scientists think that maybe — just maybe — they’ve detected 60 new extraterrestrial civilizations doing just that. At least, that’s what it could be.

[Freeman Dyson] popularized the idea of a Dyson sphere, an artificial sphere surrounding a sun to capture the maximum amount of energy, back in 1960. However, the idea is older and usually credited to [Olaf Stapledon]’s 1937 novel Star Maker. While most people think the sphere would be solid, [Dyson] himself thought it would be a swarm of disjointed collectors owing to the difficulty in creating a solid shell of the required size.

Both SETI and Fermilab have searched for what is thought to be telltale infrared radiation that scientists think would emanate from a star surrounded by spheres or swarms. Several have been located, but there is no conclusive evidence.

The new 60 were identified by analyzing data from the Gaia satellite. Again, the evidence is not conclusive, but small and dim stars that are very bright in infrared can’t be explained by conventional explanations. One way to explain at least some of the stars would be if about 16% of the star was obscured by something like a swarm of Dyson sphere collectors.

There are, of course, more jejune explanations possible. For example, the star might happen to be in front of some more distant IR source. Still, it is tantalizing to think there may be more than 60 high-tech civilizations out there either waiting to meet us or, perhaps, waiting to eat us, depending on how paranoid you are.

New Quadcopter Speed World Record Set At Nearly 500 Km/h

Making a quadcopter go fast would seem to be quite simple: just strap on powerful motors, aim the quadcopter roughly at where you want it to go fast, and let ‘er rip. Because of aerodynamics and other pesky physical laws there are a few complications to this, of course, but this didn’t deter [Luke Bell] and his father [Mike Bell] from nailing the Guinness World Record for remote-controlled quadcopters on April 21, 2024. During the official run, a top speed of 480.23 km/h was recorded, making it considerably faster than the first version they made, which hit a measly 400 km/h.

For this second iteration of the ‘got to go fast’ quadcopter, the design was scaled up, with more powerful motors and associated electronics added. Naturally, when you’re pushing brushless motors and their ESCs to their limits, stuff can get a bit hot due to the immense currents flowing through the system. This resulted in a number of battery, wire and other fires. Fortunately, the worrying aspect of in-flight stability got addressed pretty well courtesy of a professional drone trainer, and ultimately the world record attempt went off without a hitch.

An endurance test was also attempted, which reached 7.5 km at 180 km/h, and with the clear canopy in from of the camera removed, visual performance was pretty stunning, while still easily reaching 400 km/h. This might make it the perfect high-speed chase camera system.

Thanks to [Craig] for the tip.
