An anonymous reader quotes a report from Wired: A little after 6 pm ET on Wednesday, the system started blinking red for iOS developer Clay Jones. Like many devs, Jones uses a Google product called Crashlytics to keep tabs on when his app stops working. Out of nowhere, it registered tens of thousands of crashes. It also pointed to the cause: a chunk of code that Jones' app incorporates to let people log in with their Facebook accounts. By 6:30 pm, Jones had filed a bug report about the flaw in Facebook's software development kit on GitHub, the code repository. He wasn't alone. According to widespread reports and the web monitoring service Down Detector, prominent iOS apps like TikTok, Spotify, Pinterest, Venmo, and more experienced issues on Wednesday. Many users found that they crashed whenever they tried to open the apps, whether or not they used Facebook to log in.

"Yesterday, a new release of Facebook included a change that triggered crashes in some apps using the Facebook iOS SDK for some users. We identified the issue quickly and resolved it," Facebook said in a statement. That change was quite small, given its outsized impact. "It was something like a server value -- which was supposed to provide a dictionary of things -- was changed to providing a simple YES/NO instead, without warning," says iOS developer Steven Troughton-Smith. "A change that simple can break an app that isn't prepared for it."

"Pretty much all these apps -- Pinterest, Spotify, a lot of the big ones -- use the Facebook SDK for the login button," says Jones. "You'll see 'Login With Facebook.' Everyone has it, super common, great for sign-up rates because it's just a one-click thing." And lots of apps that don't use Login With Facebook still use the SDK, which is why the issue Wednesday was so widespread. [...] The good news is that Facebook did fix the issue with haste, as far as these things go. Jones says it took about two hours for things to return to normal.

"Over at ScienceDirect, they report on a French 'retrospective' study of just over 1,000 patients across all age groups with very good results," writes long-time Slashdot reader kenh. The analysis found that administration of Hydroxychloroquine (HCQ) and Azithromycin (AZ) before COVID-19 complications occur "is safe and associated with very low fatality rate in patients." From the report: Background: In France, the combination hydroxychloroquine (HCQ) and azithromycin (AZ) is used in the treatment of COVID-19.

Methods: We retrospectively report on 1061 SARS-CoV-2 positive tested patients treated with HCQ (200 mg three times daily for ten days) + AZ (500 mg on day 1 followed by 250 mg daily for the next four days) for at least three days. Outcomes were death, clinical worsening (transfer to ICU, and more than 10 day hospitalization) and viral shedding persistence (more than 10 days).

Results: A total of 1061 patients were included in this analysis (46.4% male, mean age 43.6 years -- range 14-95 years). Good clinical outcome and virological cure were obtained in 973 patients within 10 days (91.7%). Prolonged viral carriage was observed in 47 patients (4.4%) and was associated to a higher viral load at diagnosis (pA poor clinical outcome (PClinO) was observed for 46 patients (4.3%) and 8 died (0.75%) (74-95 years old). All deaths resulted from respiratory failure and not from cardiac toxicity. Five patients are still hospitalized (98.7% of patients cured so far). PClinO was associated with older age (OR 1.11), severity at admission (OR 10.05) and low HCQ serum concentration. PClinO was independently associated with the use of selective beta-blocking agents and angiotensin II receptor blockers (p less than .05). A total of 2.3% of patients reported mild adverse events (gastrointestinal or skin symptoms, headache, insomnia and transient blurred vision). On the contrary, a separate study, which has not been peer-reviewed, found the two primary outcomes for COVID-19 patients treated with hydroxychloroquine were death and the need for mechanical ventilation.

"The study analyzed only 368 patients but represented the largest look at the outcomes of COVID-19 patients treated with hydroxychloroquine -- with or without azithromycin, a common antibiotic -- anywhere in the world," The Hill reported more than two weeks ago.

UPDATE (5/9/2020): A new hydroxychloroquine study -- "the largest to date" -- was published Thursday in the prestigious New England Journal of Medicine. It concluded that Covid-19 patients taking the drug don't do any better than those not receiving the drug.

MojoKid writes: AMD unveiled two new Ryzen 3 processors recently, designed to drive its Zen 2 CPU microarchitecture into more affordable price points. The new Ryzen 3 3100 and Ryzen 3 3300X are entry-level 3rd gen Ryzen CPUs that will run in any socket AM4 motherboard, with price points of only $99 (Ryzen 3 3100) and $120 (Ryzen 3 3300X). They are both quad-core/eight-thread chips, with similar cache configurations (2MB L2 + 16MB L3), and they both include basic Wraith Stealth coolers in their retail boxes. Internally, however, these two processors are somewhat different. The Ryzen 3 3100 is setup in a 2+2 configuration with two cores active per CCX (CPU Core Complex). The Ryzen 3 3300X, however, has a 4+0 configuration, with all of its active cores residing on a single CCX. These differences should result in better overall performance for the Ryzen 3 3300X, over and above just having a higher peek clock speed of 4.3GHz, versus 3.90Ghz for the Ryzen 3 3100. In the benchmarks, these new AMD quad-core chips offer similar or better performance versus competitive Intel Core i5 chips, but at significantly lower price points.

Three U.S. senators today urged Comcast to open all of its Wi-Fi hotspots to children who lack Internet access at home during the pandemic. Ars Technica reports: A letter (PDF) from Sens. Ron Wyden (D-Ore.), Kamala Harris (D-Calif.), and Cory Booker (D-N.J.) says that Comcast recently refused a request to do so because it would cause congestion for subscribers. But the senators argue that "Comcast's excuse simply does not add up." Comcast has been praised by advocates for its pandemic response, which includes two free months of home-Internet service for new low-income subscribers, temporary suspension of its data cap, and making many of its hotspots free to the general public. But while Comcast opened up 1.5 million hotspots located at businesses and other public areas, there's another category of Comcast Wi-Fi hotspots that still require a Comcast login and subscription. Those are the hotspots that are enabled by default on Xfinity routers used by home-Internet subscribers.

Since 2013, Xfinity gateways have broadcasted a separate network that other Comcast subscribers can log in to with a Comcast username and password. Unless you've disabled the functionality, anyone within range of your Comcast router can get Internet access if they have a Comcast subscription or have paid for a temporary Wi-Fi pass. Wyden, Harris, and Booker argue that Comcast should open these hotspots to children without Internet access during the pandemic so that kids can get free broadband at home instead of having to go to a parking lot or other public places. In the letter, the senators ask Comcast to answer a list of questions by May 22. They also want the company to provide specific details on how opening up the hotspots would affect network performance.

"Please identify the specific performance issues that you anticipate would impact Comcast subscribers and their ability to get the level of service for which they pay if Comcast removed the paywall on its residential public Wi-Fi networks," the senators wrote. "For each issue you identify, please explain why the use today of a subscriber's public network by someone who has purchased an access pass from Comcast does not cause the same problem."

An anonymous reader quotes a report from Bloomberg: The messages began arriving in World Health Organization employees' inboxes in early April, seemingly innocuous emails about the coronavirus from news organizations and researchers. But a close examination revealed that they contained malicious links, and some security experts have traced the emails to a hacking group in Iran believed to be sponsored by the government. The hacking effort, which began on April 3, was an attempt to steal passwords and possibly install malware on WHO computers, according to three people familiar with the matter, who requested anonymity because they aren't authorized to talk to the news media. The incident was one of several suspected state-sponsored hacks targeting WHO officials in recent weeks, the people said.

Two of the messages sent to the WHO, which were reviewed by Bloomberg News, were designed to look like coronavirus newsletters from the British Broadcasting Corporation. A third message was tailored to look like an interview request from the American Foreign Policy Council, a conservative think tank based in Washington. It encouraged recipients to click on what looked to be a shortened Google link, which diverted to a malicious domain. Ohad Zaidenberg, lead cyber intelligence researcher at Clearsky Cyber Security, reviewed the messages for Bloomberg News, and said he believed they were sent by a group of state-sponsored Iranian hackers known as "Charming Kitten," which has been active since 2014 and previously targeted Iranian dissidents, academics, journalists and human rights activists. Flavio Aggio, the WHO's chief information security officer, confirmed the "very clever attacks" but said they'd so far been unsuccessful. "We are dealing with an information war and a cyberwar at the same time," he added.

Inkscape, the free and open-source vector graphics editor, has released version 1.0 for Linux, Windows, and macOS. It comes after three years in development and over 16 years after Inkscape's initial release. BetaNews reports: "Built with the power of a team of volunteers, this open source vector editor represents the work of many hearts and hands from around the world, ensuring that Inkscape remains available free for everyone to download and enjoy. In fact, translations for over 20 languages were updated for version 1.0, making the software more accessible to people from all over the world. A major milestone was achieved in enabling Inkscape to use a more recent version of the software used to build the editor's user interface (namely GTK+3). Users with HiDPI (high resolution) screens can thank teamwork that took place during the 2018 Boston Hackfest for setting the updated-GTK wheels in motion," explains the developers.

The devs further explain, "The extensions system has undergone some fundamental changes in version 1.0. Over the years, Inkscape users have become used to working with third-party extensions, such as various ones used for laser cutting and exporting to file formats which are not a native part of Inkscape. While outreach to extension developers was undertaken as Inkscape migrates towards Python 3 and a more logical and fully tested extensions API (now hosted in a separate repository), not all third-party extensions have been brought forward to be compatible yet. This will mean that 1.0 may not allow some users to continue with their normal extensions workflow." The blog post, official release notes, and download page are available at their respective links.

Spotify CEO Daniel Ek reiterated previous gripes he's had with Apple during an interview this week, saying its platform is still not open enough to third-party apps like the Sweden-based music streamer. But according to the cofounder of high-end speaker and home audio company Sonos, Spotify operates an even-more closed ecosystem than Apple. From a report: In a tweet posted Wednesday, Sonos cofounder John MacFarlane said it was "solid irony" that Ek was criticizing Apple's platform. "Having worked closely with both Apple and Spotify, I would say it's more significantly more difficult to work within Spotify's 'closed' ecosystem than Apple's," he wrote. "Respect and appreciate both companies, but 'open' Spotify is not." Sonos products for the most part rely on third-party services like Spotify and Apple Music to stream music, podcasts, and audiobooks through the Sonos app. Industry analysts and commentators have suggested in recent years that Apple buy Sonos to boost its struggling HomePod smart speaker business.

The MPA, MPA-Canada, and Amazon have filed a request with Github requesting that a Kodi add-on developer's account be deleted from the platform. Citing a copyright case and a permanent injunction handed down by Canada's Federal Court, the content companies claim that the account is still being used to infringe their rights. Github has left the account intact, however. TorrentFreak reports: In February 2018, a developer known online as 'Blamo' (aka 'Mr. Blamo') revealed that he, in common with several of his counterparts, had been threatened by content companies. From there the trail went cold but according to a complaint filed against Github this week, legal action in Canada followed. On September 7, 2018, a dozen companies including the studios of the MPA/MPA-Canada plus Amazon and Netflix launched a copyright infringement lawsuit at Canada's Federal Court against an individual "doing business" as Mr. Blamo.

"In the context of that action, our clients alleged that [Blamo] notably developed, hosted, promoted and distributed infringing add-ons for the Kodi media center, which provided unauthorized access to motion pictures and television content for which the copyright is owned by our clients," the MPA writes. According to Federal Court records, Blamo did not mount any kind of defense so as a result, the matter was decided in his absence. On January 15, 2019, the Federal Court handed down a final judgment, including a declaration of infringement and a permanent injunction. "The permanent injunction enjoins and restrains [Blamo] from, inter alia, hosting, distributing or promoting infringing Kodi add-ons and their repositories, including notably the 'Blamo' repository and the "Chocolate Salty Balls' infringing add-ons," the MPA adds.

The problem here is that, according to the MPA and associated companies, Blamo has a Github account where it is claimed he continues to "host and distribute infringing Kodi add-ons and their repository, including notably the Chocolate Salty Balls infringing add-on and the Blamo repository." This, the MPA says, amounts to contempt of court. What's particularly interesting here, however, is that the MPA isn't asking for the specified URLs to be deleted. Instead, it asks for Blamo's entire Github account to be deactivated instead.

Amazon workers in southern California's industrial heartland say the company's policies are forcing sick employees to work and that warehouses are refusing to comply with a state paid sick leave law meant to prevent Covid-19 outbreaks. From a report: In the Inland Empire region outside Los Angeles, Amazon workers told the Guardian they fear losing their jobs if they are ill and stay home. At least four Amazon warehouses in the region have recorded Covid-19 cases. On 1 May, Amazon ended a policy allowing unlimited unpaid time off, a measure adopted at the start of the coronavirus crisis that allowed workers to take time off for any reason. They would forgo wages, but if they were concerned about their safety or had new childcare responsibilities due to lockdowns, they could stay home without losing their jobs. Without the policy, workers say they could now be fired if they miss shifts. They worry the reversal will result in sick and vulnerable people showing up for shifts because they can't risk termination. The health concerns are particularly serious in the Inland Empire, which has some of the worst air quality in the US and disproportionately high rates of asthma and other respiratory illnesses. Employees also shared emails showing that Amazon has dismissed some paid sick leave requests by claiming a California law intended to provide supplemental sick leave during the pandemic does not apply to the warehouses.

An anonymous reader quotes a report from The New York Times: As President Trump rushes to reopen the economy, a battle has erupted between the White House and the Centers for Disease Control and Prevention over the agency's detailed guidelines to help schools, restaurants, churches and other establishments safely reopen. A copy of the C.D.C. guidance obtained by The New York Times includes sections for child care programs, schools and day camps, churches and other "communities of faith," employers with vulnerable workers, restaurants and bars, and mass transit administrators. The recommendations include using disposable dishes and utensils at restaurants, closing every other row of seats in buses and subways while restricting transit routes between areas experiencing different coronavirus infection levels, and separating children at school and camps into groups that should not mix throughout the day.

But White House and other administration officials rejected the recommendations over concerns that they were overly prescriptive, infringed on religious rights and risked further damaging an economy that Mr. Trump was banking on to recover quickly. A spokesman for the C.D.C. said the guidance was still under discussion with the White House and a revised version could be published soon. [...] The mixed signals extend to reopening guidelines: On April 16, Mr. Trump's coronavirus task force released broad guidance for states to reopen in three phases, based on case levels and hospital capacity. But the more detailed C.D.C. guidance was seen by some members of the task force and other aides as a document that could slow down the reopening effort, according to several people with knowledge of the deliberations inside the West Wing. "Protections against religious discrimination aren't suspended during an emergency. This means the federal government cannot single out religious conduct as somehow being more dangerous or worthy of scrutiny than comparable secular behavior," said Roger Severino, the director of the Office for Civil Rights at the Department of Health and Human Services and a social conservative who once headed the DeVos Center for Religion and Civil Society at the Heritage Foundation. "Governments have a duty to instruct the public on how to stay safe during this crisis and can absolutely do so without dictating to people how they should worship God."

Several federal agencies that reviewed the guidance in draft form, including the Department of Labor and the Office for Civil Rights at H.H.S., protested, saying it would be harmful to businesses and the economy and too burdensome for houses of worship.

Jeff Grubb, writing for VentureBeat: One of the tidbits revealed during the first Xbox 20/20 event today is that Dirt 5 supports 120 frames per second on Xbox Series X. Publisher Codemasters' racing game is coming in October, but it supports Smart Delivery. So if you get it for Xbox One, you'll get the Xbox Series X version at no additional cost. And what does the Xbox Series X-optimized version of Dirt 5 get you? In an interview with the Xbox team, Codemasters confirmed that Dirt 5 supports the next-gen console's high-framerate feature. This means you can drive around the rally racer at 4K and 120 frames per second. High framerate is one of a number of key features for the next-gen consoles. And that makes sense. Racing games already have nearly photorealistic visuals. More graphical effects are not going to make much of a difference to the presentation of a Dirt 5. So this enables Codemasters to put that extra horsepower toward running the game faster.

OK, so the Xbox Series X can run Dirt 5 at up to 120fps, but that's not going to matter if you don't have the right display. High-refreshrate content is common on the PC, but consoles have primarily topped out at 60fps. Because of this it hasn't matter that most TVs top out at 60Hz. But it is a problem for the next-gen consoles. To actually see Dirt 5 running at 120fps, you'll need a TV that runs at 120Hz or faster. That means the TV updates its frames 120 times every second. The good news here is that a lot of TVs already have this feature. The bad news is that even if you have an HFR panel, support is a lot more complicated than that. The issue comes down to the audio/video interface running between your TV and the Xbox Series X.

Cloudflare Chief Executive Officer Matthew Prince became a billionaire Thursday as the stock climbed to a record hours before the company's scheduled earnings report. From a report: Shares of the San Francisco-based firm advanced 14% to $28.52 at 1 p.m. in New York, giving Prince a net worth of $1.08 billion, according to the Bloomberg Billionaires Index. "Cloudflare has been aided by the surge in streaming, gaming and e-commerce as people stay at home," said Bloomberg Intelligence analyst Mandeep Singh. The firm, whose stock has soared about 90% since its September initial public offering, provides services such as firewalls, network routing and traffic management that allow cloud-based sites to operate more effectively. Prince, who helped launch Cloudflare in 2009, owns about 12.5% of the company, according to its latest proxy filing. Co-founder and Chief Operating Officer Michelle Zatlyn controls a 4.8% stake.

A hacker claims to have stolen over 500GB of data from Microsoft's private GitHub repositories, BleepingComputer reports. From the report: This evening, a hacker going by the name Shiny Hunters contacted BleepingComputer to tell us they had hacked into the Microsoft GitHub account, gaining full access to the software giant's 'Private' repositories. The individual told us that they then downloaded 500GB of private projects and initially planned on selling it, but has now decided to leak it for free. Based on the file stamps in the leaked files, the breach may have occurred on March 28th, 2020.

Google has added a very useful feature to Google Lens, its multipurpose object recognition tool. From a report: You can now copy and paste handwritten notes from your phone to your computer with Lens, though it only works if your handwriting is neat enough. In order to use the new feature, you need to have the latest version of Google Chrome as well as the standalone Google Lens app on Android or the Google app on iOS (where Lens can be accessed through a button next to the search bar). You'll also need to be logged in to the same Google account on both devices. That done, simply point your camera at any handwritten text, highlight it on-screen, and select copy. You can then go to any document in Google Docs, hit Edit, and then Paste to paste the text. And voila -- or, viola, depending on your handwriting.

New submitter Bradmont shares a report: Sidewalk Labs, a Google-affiliated company, is abandoning its plan to build a high-tech neighbourhood on Toronto's waterfront, citing what it calls unprecedented economic uncertainty. The project, dubbed Quayside, still didn't have all of the government approvals it needed to go ahead. Many had raised concerns about the privacy implications of the project and how much of the city's developing waterfront Sidewalk Labs wanted to control. The so-called "smart city" was set to feature a range of cutting edge technology, from residential towers made of timber to the use of autonomous cars and heated sidewalks. "As unprecedented economic uncertainty has set in around the world and in the Toronto real estate market, it has become too difficult to make the 12-acre project financially viable without sacrificing core parts of the plan we had developed," company CEO Dan Doctoroff said in a statement.

Toronto Mayor John Tory was quick to issue a statement saying he regrets the company's decision, but anticipates others will step in to develop the area. "Toronto's economy will come back strong after COVID-19 and we will continue to be a magnet for smart people and smart companies," he said in an email. Tory also said he plans to push Waterfront Toronto and both the provincial and federal governments to make sure any new development in the area will create new jobs and a "carbon-neutral neighbourhood" with affordable housing units and "better transportation and sustainability features."

WeChat, the Chinese messaging app, is systematically monitoring the content sent by international users to build up its censorship algorithms applied against accounts registered in China, a new study has found. From a report: Researchers at Citizen Lab, an academic research lab at the University of Toronto, determined that WeChat screens images and documents shared by accounts registered outside China after they are sent, then adds the digital signature -- or "hash" -- of any files deemed sensitive to a blacklist. Those files then cannot be sent or received by China-registered users. Numerous studies have identified WeChat's use of censorship tools against China-linked accounts, but this research provides proof for the first time that non-China registered users are also swept up in its surveillance apparatus. Published Thursday in a report called "We Chat, They Watch," the Citizen Lab findings are likely to add fuel to existing concerns, particularly in Washington, about data security and the international reach of information control tools used by Chinese tech companies.

Twitch, the online video site popular among gamers, is looking for its version of "The Bachelor." From a report: The company plans to fund a slate of original, unscripted series that would be live and interactive, airing two to three times a week, according to an internal document seen by Bloomberg. Its preferred genres are game shows, dating shows, sports, music and talk -- many of the cornerstones of reality TV. The global health crisis has provided Twitch, owned by Amazon.com Inc., a rare opportunity to broaden its audience and experiment with new kinds of programming. While many TV networks have struggled to produce shows during the pandemic, Twitch's most popular personalities have always filmed themselves from home.

Neiman Marcus on Thursday became the first major department store group to file for bankruptcy protection during the coronavirus pandemic. It's a stunning fall that follows the collapse of Barneys New York late last year and comes as shadows gather over chains like Lord & Taylor and J.C. Penney. From a report: At the end of March the coronavirus pandemic temporarily forced the closure of all 43 Neiman Marcus stores, as well as its two Bergdorf Goodman stores and Last Call outlets, all but stopping sales and crushing revenue. But while that may have been the immediate cause of Neiman's filing, its problems had been building for years. The company took on an untenable amount of debt as part of two leveraged buyouts by private-equity firms, and Neiman's did not respond quickly enough to changes in shopping habits. Together, those developments left the group in a precarious position even before the virus hit.

The pandemic has been disastrous for the already weakened retail industry. Last month, sales of clothing and accessories fell by more than half. Those numbers are only expected to get worse in April, because many stores were open for at least some of March (e-commerce, a relatively small contributor to total sales for most store chains, is not enough to save them). Earlier this week, J. Crew filed for bankruptcy. Retailers have furloughed employees, slashed corporate salaries and hoarded cash in a desperate attempt to make it to the end of the shutdown. But there is widespread acknowledgment that Neiman Marcus is not likely to be the last retailer to face the brink.

Google Authenticator, the company's code-based authentication app, has received its first update in three years, updating the app's interface for larger screens with more modern aspect ratios and delivering one of the platform's most-needed features. From a report: The Android version was last updated on August 22nd, 2017, while the iOS one was updated around a year ago to adjust it for iPhone X screens. Now, for the first time, Authenticator users will be able to easily transfer their account from one device to another without needing to manually transfer each code or disable and reenable two-factor authentication (2FA) on each account. The update introduces this feature through an import / export tool that lets you choose which accounts to include and transfer using a single QR code scan. It's a feature that competitor Authy has provided for quite some time, so it's refreshing to see it come to Authenticator, even if it's years late.

Zoom announced this morning that it has acquired Keybase, a startup with encryption expertise. From a report: Keybase, which has been building encryption products for several years including secure file sharing and collaboration tools, should give Zoom some security credibility as it goes through pandemic demand growing pains. The company has faced a number of security issues in the last couple of months as demand as soared and exposed some security weaknesses in the platform. As the company has moved to address these issues, having a team of encryption experts on staff should help the company build a more secure product. In a blog post announcing the deal, CEO Eric Yuan said they acquired Keybase to give customers a higher level of security, something that's increasingly important to enterprise customers as more operations are relying on the platform, working from home during the pandemic.

An anonymous reader quotes a report from AppleInsider: Apple has been hit with a class-action lawsuit claiming that the company concealed the so-called "stage lighting" issue experienced by some 2016 MacBook Pro owners. Dubbed "stage lighting" due to abnormal backlighting patterns emanating from the bottom of an impacted MacBook Pro's display, the problem was tied to stress or tearing on the laptop's cable when the lid was opened and closed repeatedly. Apple eventually launched a repair program for the issue in 2019 and quietly fixed the underlying culprit in the next generation of MacBook.

On Wednesday, Los Angeles resident Mahan Taleshpour lodged a complaint in the U.S. District Court of the Northern District of California alleging that Apple was aware of the defect in its product and failed to disclose the issue to consumers. The plaintiff claims that his 2016 15-inch MacBook Pro experienced stage lighting effects in January 2020, but he was left responsible for the full cost of the display repair due to the fact that the repair program only covers 13-inch MacBook Pro models released in 2016. He added that the cost to repair the display was quoted as $850, adding that he's been unable to repair the device since the COVID-19 outbreak. [...] The plaintiff is seeking an official disclosure about the "defective nature" of the display cables, restitutions for MacBook Pro repair costs or economic losses, an expansion of AppleCare and repair program service to 15-inch models, and legal fees.

Stephenmg writes: The smart home hub Wink, which was purchased by Will.i.am in 2017, is giving users until May 13th to opt into a subscription for $4.99 per month. If users do not opt-in, the hub becomes a brick. "Long term costs and recent economic events" prompted the move, according to Wink, and the company didn't want to sell user data to offset the costs of running services for free.

Slashdot reader thereitis shares a report from Ars Technica that "delves into the reversing community's efforts to produce usable C source code from N64 game binaries." Here's an excerpt: Early this week, with little warning, the Internet was graced with a Windows executable containing a fully playable PC port of Super Mario 64. Far from being just a usual emulated ROM, this self-contained program enables features like automatic scaling to any screen resolution, and players are already experimenting with adding simple graphics-card-level reshaders, including ray-tracing, as well. The PC port -- which was released with little buildup and almost no promotion -- wasn't built from scratch in a modern game engine, in the manner of some other now-defunct Super Mario 64 porting projects. And its release has nothing to do with a recent leak of internal Nintendo files dating back to the Gamecube days. Instead, the port seems to be a direct result of a years-long effort to decompile the Super Mario 64 ROM into parsable C code. This kind of reverse-engineering from raw binary to easy-to-read code isn't a simple process, but it's an effort that a growing community of hobbyist decompilers is undertaking to unlock the secrets behind some of their favorite games.

According to research published in the journal AIP Advances, scientists have created a prototype jet engine that compresses air and ionizes it with microwaves, generating plasma that thrusts it forward. ScienceAlert reports: There's a long way to go between a proof-of-concept prototype and installing an engine in a real plane. But the prototype was able to launch a one-kilogram (2.2-pound) steel ball 24 millimeters (almost one inch) into the air. That's the same thrust, proportional to scale, as a conventional jet engine. "Our results demonstrated that such a jet engine based on microwave air plasma can be a potentially viable alternative to the conventional fossil fuel jet engine," lead researcher and Wuhan University engineer Jau Tang said in a press release.
