Big-endian testing with QEMU

I assume I don't have to explain the difference between big-endian and little-endian systems to the average OSNews reader, and while most systems are either dual-endian or (most likely) little-endian, it's still good practice to make sure your code works on both. If you don't have a big-endian system, though, how do you do that? When programming, it is still important to write code that runs correctly on systems with either byte order (see for example The byte order fallacy). But without access to a big-endian machine, how does one test it? QEMU provides a convenient solution. With its user mode emulation we can easily run a binary on an emulated big-endian system, and we can use GCC to cross-compile to that system. ↫ Hans Wennborg If you want to make sure your code isn't arbitrarily restricted to little-endian, running a few tests this way is worth it.

Fan Fiction Website AO3 Exits Beta After 17 Years

Archive of Our Own (AO3) is officially dropping its "beta" label after 17 years. The Organization for Transformative Works, the nonprofit behind the fanfiction site, said the site will keep evolving with new improvements even though it's no longer technically in beta. "As the AO3 software has been stable for a long time, the change is mostly cosmetic and does not indicate that everything is finalized or perfectly working," the organizations says. "Exiting beta doesn't mean we'll stop continuing to improve AO3 -- our volunteer coders and community contributors will still be working to add to and improve AO3 every day." Some of the features it's introduced over the years include a tag system, offline fanworks downloads, privacy settings that let creators restrict access to their work, and new modes for multi-chapter works. As it stands, the site says it has more than 10 million registered users and 17 million fanworks.

Tech Companies Are Trying To Neuter Colorado's Landmark Right-to-Repair Law

An anonymous reader quotes a report from Wired: Today at a hearing of the Colorado Senate Business, Labor, and Technology committee, lawmakers voted unanimously to move Colorado state bill SB26-090 -- titled Exempt Critical Infrastructure from Right to Repair -- out of committee and into the state senate and house for a vote. The bill modifies Colorado's Consumer Right to Repair Digital Electronic Equipment act, which was passed in 2024 and went into effect in January 2026. While the protections secured by that act are wide, the new SB26-090 bill aims to "exempt information technology equipment that is intended for use in critical infrastructure from Colorado's consumer right to repair laws." The bill is supported by tech manufacturers like Cisco and IBM, according to lobbying disclosures. These are companies that have vested interests in manufacturing things like routers, server equipment, and computers and stand to profit if they can control who fixes their products and the tools, components, and software used to make those upgrades and repairs. They also cite cybersecurity concerns, saying that giving people access to the tools and systems they would need to repair a device could also enable bad actors to use those methods for nefarious means. (This is a common argument manufacturers make when opposing right-to-repair laws.) [...] During the hearing, more than a dozen repair advocates spoke from organizations like Pirg, the Repair Association, and iFixit opposing the bill. YouTuber and repair advocate Louis Rossmann was there. The main problem, repair advocates say, is that the bill deliberately uses vague language to make the case for controlling who can fix their products. [...] The Colorado Labor and Technology committee advanced the bill, but it still needs to go through votes on the Colorado Senate and House floors before going into effect. Those votes may take place as early as next week. Regardless of how the bill goes in the state, it's likely that manufacturers will continue their push to alter or undo repair legislation in other states across the country. "The 'information technology' and 'critical infrastructure' thing is as cynical as you can possibly be about it," says Nathan Proctor, the leader of Pirg's US right-to-repair campaign. "It sounds scary to lawmakers, but it just means the internet." The current wording of the bill "leaves it up to the manufacturers to determine which items they will need to provide repair tools and parts to owners and independent repairers and which ones they don't," says Danny Katz, executive director CoPIRG, the Colorado branch of the consumer advocate group Pirg. "This is a bad policy and would be a big step back for Coloradans' repair rights." iFixit CEO Kyle Wiens said in the hearing: "There's a general principle in cybersecurity that obscurity is not security," iFixit CEO Kyle Wiens said in the hearing. "The money that's behind the scenes, that's what's driving the bill."

College Student, Cat Meme Helped Crack Massive Botnet Case

The Wall Street Journal shares the "wild behind-the-scenes story" of how the world's largest and most destructive botnet was uncovered and taken down, writes Slashdot reader sturgeon. "At times, the network known as Kimwolf included more than a million compromised home Android devices and digital photo frames -- enough DDoS firepower to disrupt internet traffic across the U.S. and beyond." From the report: Sitting in his dorm room at the Rochester Institute of Technology, Benjamin Brundage was closing in on a mystery that had even seasoned internet investigators baffled. A cat meme helped him crack the case. A growing network of hacked devices was launching the biggest cyberattacks ever seen on the internet. It had become the most powerful cyberweapon ever assembled, large enough to knock a state or even a small country offline. Investigators didn't know exactly who had built it -- or how. Brundage had been following the attacks, too -- and, in between classes, was conducting his own investigation. In September, the college senior started messaging online with an anonymous user who seemed to have insider knowledge. As they chatted on Discord, a platform favored by videogamers, Brundage was eager to get more information, but he didn't want to come off as too serious and shut down the conversation. So every now and then he'd send a funny GIF to lighten the mood. Brundage was fluent in the memes, jokes and technical jargon popular with young gamers and hackers who are extremely online. "It was a bit of just asking over and over again and then like being a bit unserious," said Brundage. At one point, he asked for some technical details. He followed up with the cat meme: a six-second clip that showed a hand adjusting a necktie on a fluffy gray cat. Brundage didn't expect it to work, but he got the information. "It took me by surprise," he said. Eventually the leaker hinted there was a new vulnerability on the internet. Brundage, who is 22, would learn it threatened tens of millions of consumers and as much as a quarter of the world's corporations. As he unraveled the mystery, he impressed veteran researchers with his findings -- including federal law enforcement, which took action against the network two weeks ago. Chad Seaman, a researcher at Akamai, joked at one point that the internet could go down if Brundage spent too much time on his exams.

How to turn anything into a router

I don't like to cover "current events" very much, but the American government just revealed a truly bewildering policy effectively banning import of new consumer router models. This is ridiculous for many reasons, but if this does indeed come to pass it may be beneficial to learn how to "homebrew" a router. Fortunately, you can make a router out of basically anything resembling a computer. ↫ Noah Bailey I genuinely can't believe making your own router with Linux or BSD might become a much more widespread thing in the US. I'm not saying it's a bad thing - it'll teach some people something new - but it just feels so absurd.

Microsoft Copilot is now injecting ads into pull requests on GitHub

Why do so many people keep falling for the same trick over and over again? With an over $400 billion gap between the money invested in AI data centers and the actual revenue these products generate, Silicon Valley slowly returned to the tested and trusted playbook: advertising. Now, ads are starting to appear in pull requests generated by Copilot. According to Melbourne-based software developer Zach Manson, a team member used the AI to fix a simple typo in a pull request. Copilot did the job, but it also took the liberty of editing the PR's description to include this message: "⚡ Quickly spin up Copilot coding agent tasks from anywhere on your macOS or Windows machine with Raycast." ↫ David Uzondu at Neowin It turns out that Microsoft has added ads to over 1.5 million Copilot pull requests on GitHub, and they're even appearing on GitLab, one of the GitHub alternatives. The reasoning is clear, too, of course: "AI" companies and investors have poured ungodly amounts of money in "AI" that is impossible to recover, even with paying customers. As such, the logical next step is ads, and many "AI" companies are already starting to add advertising to their pachinko machines. It was only a matter of time before Copilot would start inserting ads into the pull requests it ejaculates over all kinds of projects. This isn't the first time a once-free service turns on its users, but it's definitely one of the quickest turnarounds I've ever seen. Usually it takes much longer before companies reach the stage of putting ads in their products to plug any financial bleeding, but with the amount of money poured into this useless black hole, it really shouldn't be surprising we're already there. I'm sure Copilot's competitors, like Claude, will soon follow suit. They're enshittifying Git, and developers are just letting it happen. No wonder worker exploitation is so rampant in Silicon Valley.
