Over 100 published studies may have incorrect results thanks to a glitchy piece of Python code discovered by researchers at the University of Hawaii.

An anonymous reader quotes Motherboard: The glitch caused results of a common chemistry computation to vary depending on the operating system used, causing discrepancies among Mac, Windows, and Linux systems. The researchers published the revelation and a debugged version of the script, which amounts to roughly 1,000 lines of code, on Tuesday in the journal Organic Letters.

"This simple glitch in the original script calls into question the conclusions of a significant number of papers on a wide range of topics in a way that cannot be easily resolved from published information because the operating system is rarely mentioned," the new paper reads. "Authors who used these scripts should certainly double-check their results and any relevant conclusions using the modified scripts in the [supplementary information]."

Yuheng Luo, a graduate student at the University of Hawaii at Manoa, discovered the glitch this summer when he was verifying the results of research conducted by chemistry professor Philip Williams on cyanobacteria... Under supervision of University of Hawaii at Manoa assistant chemistry professor Rui Sun, Luo used a script written in Python that was published as part of a 2014 paper by Patrick Willoughby, Matthew Jansma, and Thomas Hoye in the journal Nature Protocols . The code computes chemical shift values for NMR, or nuclear magnetic resonance spectroscopy, a common technique used by chemists to determine the molecular make-up of a sample. Luo's results did not match up with the NMR values that Williams' group had previously calculated, and according to Sun, when his students ran the code on their computers, they realized that different operating systems were producing different results.

Sun then adjusted the code to fix the glitch, which had to do with how different operating systems sort files.
The researcher who wrote the flawed script told Motherboard that the new study was "a beautiful example of science working to advance the work we reported in 2014. They did a tremendous service to the community in figuring this out."

Sun described the original authors as "very gracious," saying they encouraged the publication of the findings.

Last year, Apple software chief Craig Federighi said developers would be able to easily bring their iPad apps to Mac computers, essentially letting coders write an app once and deploy it across millions more devices. So far, the reality has fallen short for some developers and is even leaving consumers paying twice for apps. From a report: Major app developers and service providers like Netflix are also demurring on taking part, at least at this early stage. Apple rolled out Catalyst, the technology to transition iPad apps into Mac versions, on Monday. It's the initial step toward a bigger goal: By 2021, developers should be able to build an app once and have it work on iPhones, iPads and Mac computers through a single, unified App Store. But the first iteration, which appears to still be quite raw and in a number of ways frustrating to developers, risks upsetting users who may have to pay again when they download the Mac version of an iPad app they've already bought.

"As a user, I don't want to pay again just to have the same app," said longtime Apple developer Steven Troughton-Smith. "As a developer, I don't want my users to have to make that decision." James Thompson has had to work harder than he expected to get his popular PCalc calculator iPad app running well on Mac computers. Getting paid a second time for that extra work makes sense for developers, but consumers may not immediately understand that after Apple made the porting process sound as easy as checking a box, he said. Kevin Reutter, who has brought his Planny app to Mac computers, called the situation "sad."

iTunes is officially dead with the release of macOS Catalina today. Apple decided to break apart the app into separate Apple Music, Podcasts and TV apps. "Each is better at its individuals task than it was as a section within iTunes, which was teetering on collapse like the Jenga tower of various functions it supports," writes Dieter Bohn via The Verge.

"In the early days, iTunes was simply a way to get music onto Apple's marquee product, the iPod music player," reports Snopes. "Users connected the iPod to a computer, and songs automatically synced -- simplicity unheard of at the time." It was the first service to make songs available for 99 cents apiece, and $9.99 for most albums -- convincing many people to buy music legally than seek out sketchy sites for pirated downloads. "But over time, iTunes software expanded to include podcasts, e-books, audiobooks, movies and TV shows," recalls Snopes. "In the iPhone era, iTunes also made backups and synced voice memos. As the software got bloated to support additional functions, iTunes lost the ease and simplicity that gave it its charm. And with online cloud storage and wireless syncing, it no longer became necessary to connect iPhones to a computer -- and iTunes -- with a cable."

What did you like or dislike about iTunes? When you look back at the media player, what are you reminded of?

It's happening a little later in the season than usual, but Apple's latest version of macOS is available to download today. From a report: Catalina arrives on the heels of iOS 13, which saw several back-to-back updates after an initially rough launch. For what it's worth, I've been using successive versions of the Catalina beta as my daily driver for months now and can assure you that the latest build is stable enough to safely install. [...] Speaking of games, today also marks the first time that Catalina beta users will have been able to play Apple Arcade games. If you're wondering how the heck you'll play those titles from your Mac, it's worth a reminder that many Arcade games support Xbox and PlayStation controllers.

Also new in this release: As you browse episodes in the podcast app, you'll see avatars for guests and hosts. Apple also says it's made some small usability tweaks to Sidecar, the feature that allows you to use an iPad as a secondary Mac display. You'll also notice more promotional Apple TV+ material in the new TV app, which makes sense -- the streaming service launches November 1st. It'll cost $4.99 a month, but Apple is offering a free year with the purchase of a new Mac, iPhone, iPad or Apple TV.

ugen (Slashdot reader #93,902) writes: Something I discovered today, while trying to change a MAC address on a new MacBook Air (as I did for years on other MacBooks): ifconfig en0 ether "new mac" no longer works. It appears that this is a change made sometime last year, applicable to all Apple newer MacBooks.

Implications of permanently fixed MAC addresses on privacy and security are hard to underestimate. Given that Windows now supports complete Wifi MAC address randomization — I am sad to admit that Microsoft looks like a champion of privacy here. What are your thoughts? Solutions anyone knows of (I'll take a reasonable technical hack).

Here are a few mentions of this elsewhere:
Mac Rumors forums
The GitHub repo for SpoofMAC
A discussion on Stack Overflow
I've seen other theories about what's going on, though the bigger question is still what's the solution? Leave your own thoughts and suggestions in the comments.

And did MacOS stop allowing changes to wifi MAC addresses?

An anonymous reader writes: "DDoS-for-hire services, also known as DDoS booters, or DDoS stressors, are abusing macOS systems to launch DDoS attacks," reports ZDNet. "These attacks are leveraging macOS systems where the Apple Remote Desktop feature has been enabled, and the computer is accessible from the internet, without being located inside a local network, or protected by a firewall. More specifically, the attackers are leveraging the Apple Remote Management Service (ARMS) that is a part of the Apple Remote Desktop (ARD) feature. When users enable the Remote Desktop capability on their macOS systems, the ARMS service starts on port 3283 and listens for incoming commands meant for the remote Mac." Hackers have figured out a way to bounce traffic off these ports and carry out DDoS attacks with the help of internet connected Macs. Nearly 40,000 macOS systems are currently connected online and can be used to send out DDoS attacks.

Microsoft today announced that Windows Virtual Desktop has hit worldwide general availability. As a result, you can deploy and scale your Windows desktops and apps on Azure "in minutes," the company said today. From a report: Think of Windows Virtual Desktop as a tool for deploying and scaling Windows desktops and apps on Azure with built-in security and compliance. The Azure-based service provides a virtualized multi-session Windows 10 experience and Office 365 ProPlus virtual desktop on any device. The Windows Virtual Desktop client is available on Windows, Mac, Android, iOS, and HTML 5. Windows Virtual Desktop also supports Windows Server Remote Desktop Services (RDS) desktops and apps in a shared public cloud. Microsoft announced Windows Virtual Desktop in September 2018, but only in private preview.

Developer Riley Testut is launching an alternative to Apple's App Store, called AltStore, that theoretically lets you "push the boundaries" of iOS without either jailbreaking or worrying that Apple will pull access. Engadget reports: AltStore works by fooling your device into believing that you're a developer sideloading test apps. It uses an app on your Mac or Windows PC to re-sign apps every seven days, using iTunes' WiFi syncing framework to reinstall them on your device before they expire. You only need a free Apple ID (a throwaway will do) to install apps that Apple would never allow, such as Testut's Delta emulator for Nintendo consoles.

In theory, there's not much Apple can do to easily shut things down. It could take down individual accounts, but you could just create another Apple ID if needed. Also, iOS only looks for an excessive number of app provisioning profiles, not the number of apps you have installed. So long as AltStore manages those profiles, Apple doesn't know if you're running one app or twenty. Testut told The Verge that measures to block AltStore would break key functionality for developers or iTunes syncing. AltStore is available in preview form now, with a formal launch due on September 28th. "People who back Testut's Patreon will also have the option to install almost any app, not just those in the store," the report adds.

A faulty Google Chrome update is likely to blame for the issue Monday that resulted in Mac Pro workstations being rendered unusable at a number of Hollywood studios. "We recently discovered that a Chrome update may have shipped with a bug that damages the file system on MacOS machines," the company wrote in a forum post. "We've paused the release while we finalize a new update that addresses the problem." Variety reports: Reports of Mac Pro workstations refusing to reboot started to circulate among video editors late Monday. At the time, the common denominator among impacted machines seemed to be the presence of Avid's Media Composer software. The issue apparently knocked out dozens of machines at multiple studios, with one "Modern Family" reporting that the show's entire editing team was affected. Avid's leadership updated users of its software throughout the day, advising them to back up their work and not to reboot their machines.

The real culprit was apparently a recent release of Google's Keystone software, which is included in its Chrome browser to automatically download updates of the browser. On computers that had Apple's System Integrity Protection disabled, the update corrupted the computer's file system, making it impossible to reboot. System Integrity Protection is an Apple technology that is meant to ensure that malicious software doesn't corrupt core system files. Google advised affected users on how to uninstall the Chrome update, and also suggested that most users may not be at risk at all. "If you have not taken steps to disable System Integrity Protection and your computer is on OS X 10.9 or later, this issue cannot affect you," the forum post reads. A possible connection to Chrome was first detailed on the Mr. Macintosh blog Tuesday afternoon. As for why several Hollywood studios were hit the hardest, one theory suggests it's because many of the video editors had to disable System Integrity Protection in order to work with external audio and video devices that are common in professional editing setups.

Variety also suggests that the hardware dongles used for licensing Avid may have played some role in the shut-downs.

tearmeapart writes (edited to add more details): Cloudflare is opening up its security and speed-focused mobile VPN service called WARP and WARP Plus to the general public. WARP is a mobile app for Android and Apple to establish a VPN to CloudFlare's huge global network. Cloudflare is promising:
1. No user-identifiable log data to disk;
2. No selling browsing data;
3. No need to provide any personal information
4. Regularly get audited. This is the second time Cloudflare is launching Warp. The VPN builds on Cloudflare's existing mobile app 1.1.1.1, which encrypts domain name system connections. But Warp goes beyond this protection to encrypt the whole journey from your device to a web server and back -- even if the website itself still isn't offering HTTPS web encryption. And all of this happens quickly, without draining your battery, and without complicated setup. In an interview with Wired, Cloudflare CEO Matthew Prince said: Yeah, what we thought was going to be easy back in April turned out to be a lot harder than we expected. We had been testing this primarily in San Francisco and Austin and London, which is where the teams that were working on this are based. But as soon as users started to get anywhere that didn't have a fairly reliable internet connection, just all hell broke loose. The report adds: In describing the hurdles Cloudflare faced getting Warp off the ground, John Graham-Cumming, the company's chief technology officer, and Dane Knecht, its head of product strategy, note that many of the challenges came from dealing with interoperability issues between mobile device models, operating system versions, and different mobile network and Wi-Fi configurations around the world. For example, Warp is built on a newer secure communication protocol for VPNs known as WireGuard, which isn't ubiquitous yet and therefore isn't always natively supported by devices. The team also faced challenges dealing with web protocols and standards that are implemented inconsistently across different wireless carriers and internet service providers around the world. Cloudflare's 1.1.1.1 focuses on encrypting DNS connections specifically, but Warp aims to encompass everything in one protected tunnel. Keeping everything together as data traverses the labyrinth of servers that make up the internet, including Cloudflare's own massive network, was tough. Warp is free to use without any bandwidth caps or limitations. But Warp Plus, which is being offered through a monthly subscription fee, offers a "faster version of Warp that you can optionally pay for. The fee for Warp Plus varies by region and is designed to approximate what a McDonald's Big Mac would cost in the region. On iOS, the Warp Plus pricing as of the publication of this post is still being adjusted on a regional basis, but that should settle out in the next couple days. Warp Plus uses Cloudflare's virtual private backbone, known as Argo, to achieve higher speeds and ensure your connection is encrypted across the long haul of the Internet. We charge for it because it costs us more to provide," the company said in the blog post.

A possible computer virus attack has knocked out Mac Pro workstations for many film and TV editors across Los Angeles. According to Variety, the issue -- which is causing the workstations to refuse to reboot -- is widespread among users of Mac Pro computers running older versions of Apple's operating system as well as Avid's Media Composer software. From the report: Avid said in a statement that it was aware of the issue: "Avid is aware of the reboot issue affecting Apple Mac Pro devices running some Avid products, which arose late yesterday. This issue is top priority for our engineering and support teams, who have been working diligently to determine and resolve the root cause. As we learn more, we will immediately publish information -- directly to our customers and via our community forums and social media platforms -- in order to resolve this issue for all affected customers and prevent any further issues."

"A lot of L.A. post shops and people out on shows having their Macs slowly crash," reported video post-production consultant Matt Penn on Twitter. Freelance film editor Marcus Pun reposted a message from a popular Avid Facebook user group, advising users not to turn off their workstations. Other users reported that multiple computers at their company were affected by the issue, with social media chatter indicating that a number of different companies, and even major shows like "Modern Family," were affected by the issue. UPDATE: The issue appears to be caused by a Google Chrome update gone haywire.

dryriver writes: For the benefit of those who are not much into 3D technologies, as far back as the year 2000 and even earlier, there was excitement about "Web3D" -- interactive 3D content embedded in HTML webpages, using technologies like VRML and ShockWave 3D. 2D vector-based Flash and Flash animation was a big deal back then. Very popular with internet users. The more powerful but less installed ShockWave browser plugin -- also made by Macromedia -- got a fairly capable DirectX 7/OpenGL-based realtime 3D engine developed by Intel Labs around 2001 that could put 3D games, 3D product configurators and VR-style building/environment walkthroughs into an HTML page, and also go full-screen on demand. There were significant problems on the hardware side -- 20 years ago, not every PC or Mac connected to the internet had a decently capable 3D GPU by a long shot. But the 3D software technology was there, it was promising even then, and somehow it died -- ShockWave3D was neglected and killed off by Adobe shortly after they bought Macromedia, and VRML died pretty much on its own.

Now we are in 2019. Mobile devices like smartphones and tablets, PCs/Macs as well as Game Consoles have powerful 3D GPUs in them that could render great interactive 3D experiences in a web browser. The hardware is there, but 99% of the internet today is in flat 2D. Why is this? Why do tens of millions of gamers spend hours in 3D game worlds every day, and even the websites that cater to this "3D loving" demographic use nothing but text, 2D JPEGs and 2D YouTube videos on their webpages? Everything 3D -- 3D software, 3D hardware, 3D programming and scripting languages -- is far more evolved than it was around 2000. And yet there appears to be very little interest in putting interactive 3D anything into webpages. What causes this? Do people want to go into the 2020s with a 2D-based internet? Is the future of the internet text, 2D images, and streaming 2D videos?

Apple has confirmed Monday that it will manufacture the redesigned Mac Pro in Texas. The company said it will assemble the workstation at the same Austin, Texas plant that has produced the cylindrical Mac Pro since 2013. The reason for the move: exemptions from Trump's China tariffs for "certain necessary components" in the system. Engadget reports: Apple had received 10 out of its 15 requested exemptions for components like partial circuit boards. While Apple has a network of U.S. suppliers for its products, many of the parts for computers (and those of rivals) are still made in China -- the company wouldn't have seen much benefit from U.S. assembly if it had to pay a premium for some of the Mac Pro's key ingredients.

CEO Tim Cook (who hinted at this possibility in July) touted this as part of Apple's existing commitment to American jobs, including its recent investment into Corning. However, it's not necessarily the coup it sounds like at first blush. Apple can produce the Mac Pro stateside due to both its low volume (few people will buy a $6,000 tower for home use) and the high levels of automation at the Austin plant. This won't lead to an abundance of new jobs, and it may still be more practical to make high-volume products like iPhones and MacBooks in China even if future tariffs cut into Apple's profit margins.

Mozilla has quietly launched a new product for enterprise customers: Ability to buy paid premium support for Firefox. From a report: The premium enterprise support for Firefox costs $10 per supported installation and offers customers the ability to submit bugs privately, get critical security bug fixes, get access to a private customer portal, get access to the enterprise critical issues distribution list, and have the ability to contribute to Firefox and its roadmap. According to Mozilla, it will support Firefox installations as long as they are running on machines that meet the system requirements. Windows, Mac, and Linux based operating systems are listed in the systems requirements so all platforms should be covered by the premium support.

Google is starting to make its Chrome 77 browser update available to Windows, Mac, iOS, and Android this week. While there are many visual changes to Chrome this time, Google is introducing a new send webpage to devices feature. From a report: You can right-click on a link and a new context menu will appear that simply lets you send links to other devices where you use Chrome. If you're using Chrome on iOS you'll need to have the app open and a small prompt will appear to accept the sent tab. The feature has started showing up on Windows, Android, and iOS versions of Chrome, but it doesn't appear to be enabled in the macOS variant just yet. Chrome has long supported the ability to browse your open and recent tabs across multiple devices, but this send to device feature just makes things a little quicker if you're moving from browsing on a PC or laptop to a phone or vice versa.

Apple's Arcade video game subscription service is launching on September 19 for $4.99 per month for up to six members in your family. "There will be new games released every month, and will have perks like game guides and sneak peeks," reports Gizmodo. "In addition to a new Frogger, Apple also demoed new games Sayonara Wild Hearts and Shinsekai Into the Depths." From the report: Thanks to the little Apple did share ahead of its September 10 event, we knew that Arcade would launch with more than 100 different games, including a new Sonic the Hedgehog game and the revamped Frogger. Apple also said in March that Arcade wouldn't have ads or require additional purchases and that games would be available offline and playable on an iPhone, iPad, Apple TV, or Mac. And rather than releasing as a dedicated app, Arcade will release within the App Store as a new tab.

An anonymous reader shares a report: When Microsoft bought 6Wunderkinder, the developer of Wunderlist, in 2015, officials said they planned to shut down that task-management app at some point and replace it with its own To Do app. That move still hasn't happened. But this week, Microsoft is rolling out a redesign of To Do that attempts to make it look more like Wunderlist. On September 9, Microsoft introduced the redesigned To Do, which has smaller headers and more colors. The app is more customizable now with a variety of backgrounds, "including the beloved Berlin TV tower that was a feature in Wunderlist." The app can sync across Mac, iOS, Android, Windows and the Web. And it integrates with Microsoft work or school email accounts; hosted email accounts like Outlook, Hotmail or Live; Microsoft Planner; and Microsoft Launcher on Android. Just so it happens, last week Wunderlist founder Christian Reber said that he'd like to buy Wunderlist back from Microsoft. Today he tweeted "GREAT timing," in regards to Microsoft's To Do makeover.

dryriver writes: The Amiga was a remarkable machine at the time it was released -- 1985. It had a multitasking capable GUI-driven OS and a mouse. It had a number of cleverly designed custom chips that gave the Amiga amazing graphics and sound capabilities far beyond the typical IBM/DOS PCs of its time. The Amiga was the multimedia beast of its time -- you could create animated and still 2D or 3D graphics on it, compose sophisticated electronic music, develop 2D or 3D 16-Bit games, edit and process digital video (using Video Toaster), and of course, play some amazing games. And after the Amiga -- as well as the Atari ST, Archimedes and so on -- died, everybody pretty much had to migrate to either the PC or Mac platforms. If Commodore and the Amiga had survived and thrived, there might have been four major desktop platforms in use today: Windows, OSX, AmigaOS and Linux. And who knows what the custom chips (ASICs? FPGAs?) of an Amiga in 2019 might have been capable of -- Amiga could possibly have been the platform that makes nearly life-like games and VR/AR a reality, and given Nvidia and AMD's GPUs a run for their money.

What do you think the computing landscape in 2019 would have looked like if the Amiga and AmigaOS as a platform had survived? Would Macs be as popular with digital content creators as they are today? Would AAA games target Windows 7/8/10 by default or tilt more towards the Amiga? Could there have been an Amiga hardware-based game console? Might AmigaOS and Linux have had a symbiotic existence of sorts, with AmigOS co-existing with Linux on many enthusiast's Amigas, or even becoming compatible with each other over time?

As promised, popular RSS reader NetNewsWire, which changed ownership last year, has released v5.0. From a blog post: NetNewsWire 5.0 is shipping! In case you haven't been following along until just now: NetNewsWire is an open source RSS reader for Mac. It's free! You can just download it and use it. No strings. It's designed to be stable, fast, and free of bugs. It doesn't have a lot of features yet, and that's because we prioritized quality over features. We will be adding more features, of course, but not quickly. We're also working on an iOS app.

Qantas airlines is now restricting MacBook Pro laptops from checked-in luggage on concern that batteries could catch fire. All 15-inch versions of Apple's MacBook Pro must be carried in the cabin and switched off, Qantas said in a statement Wednesday. The rule went into effect Tuesday morning. "Rival Virgin Australia went further on Aug. 26, banning all Apple laptops from checked-in luggage," adds Bloomberg. From the report: Australia's two biggest airlines join a growing list of carriers and jurisdictions across the world cracking down on the portable computers out of concern some could self-combust. The models in question are some 15-inch MacBook Pros sold from September 2015 to February 2017. Apple issued the recall in June, saying "in a limited number of older generation 15-inch MacBook Pro units, the battery may overheat and pose a fire safety risk." Singapore Airlines Ltd. and Thai Airways International PCL have already stopped passengers from taking any of the affected models on their aircraft.
