Earlier this month, Microsoft made the source code for its Windows calculator available on GitHub. This has spurred developers to add new features to the app, like a new graphing mode that will make its way to the official Windows Calculator app. The "Graphing Mode" is one of 30+ suggestions that open-source contributors have proposed so far. The ZDNet reports: As its name implies, Graphing Mode will allow users to create graphs based on mathematical equations, in a similar way to Matlab's (way more advanced) Plotting Mode. The feature was proposed by Microsoft engineer Dave Grochocki, also a member of the Windows Calculator team. In a GitHub issue Grochocki submitted to support his proposal, he argued that a graphing mode would help students learn algebra easier.

"High school algebra is the gateway to mathematics and all other disciplines of STEM," Grochocki said. "However, algebra is the single most failed course in high school, as well as the most failed course in community college." By adding a Graphing Mode to Windows Calculator, an app included with all Windows 10 versions, the Microsoft engineer hopes to provide students and teachers with a free tool to help schools across the world. "Physical graphing calculators can be expensive, software solutions require licenses and configuration by school IT departments, and online solutions are not always an option," he added. "Graphing capabilities in their daily tools are essential for students who are beginning to explore linear algebra as early as 8th grade. [...] At present, Windows Calculator does not currently have the needed functionality to meet the demands of students."

There's no timeline for when the new graphing mode will arrive, but it should arrive soon.

The recent Boeing 737 MAX crashes involving an Ethiopian Airlines flight and a Lion Air flight may have been a result of two missing safety features that Boeing charged airlines extra for (Warning: source may be paywalled; alternative source). The New York Times reports that many low-cost carriers like Indonesia's Lion Air opted not to buy them so they could save money, even though some of these systems are fundamental to the plane's operations. "Now, in the wake of the two deadly crashes involving the same jet model, Boeing will make one of those safety features standard as part of a fix to get the planes in the air again," the report says. From the report: It is not yet known what caused the crashes of Ethiopian Airlines Flight 302 on March 10 and Lion Air Flight 610 five months earlier, both after erratic takeoffs. But investigators are looking at whether a new software system added to avoid stalls in Boeing's 737 Max series may have been partly to blame. Faulty data from sensors on the Lion Air plane may have caused the system, known as MCAS, to malfunction, authorities investigating that crash suspect.

The jet's software system takes readings from one of two vanelike devices called angle of attack sensors that determine how much the plane's nose is pointing up or down relative to oncoming air. When MCAS detects that the plane is pointing up at a dangerous angle, it can automatically push down the nose of the plane in an effort to prevent the plane from stalling. Boeing's optional safety features, in part, could have helped the pilots detect any erroneous readings. One of the optional upgrades, the angle of attack indicator, displays the readings of the two sensors. The other, called a disagree light, is activated if those sensors are at odds with one another. The angle of attack indicator will remain an option that airlines can buy. Neither feature was mandated by the Federal Aviation Administration. All 737 Max jets have been grounded. "Boeing will soon update the MCAS software, and will also make the disagree light standard on all new 737 Max planes," the report adds, citing a person familiar with the changes. "Boeing started moving on the software fix and the equipment change before the crash in Ethiopia."

Slashdot reader Futurepower(R) adds to the story: The FBI has joined the criminal investigation into the certification of the Boeing 737 MAX, lending its considerable resources to an inquiry already being conducted by U.S. Department of Transportation agents, according to people familiar with the matter. "The federal grand jury investigation, based in Washington, D.C., is looking into the certification process that approved the safety of the new Boeing plane, two of which have crashed since October.

An anonymous reader quotes a report from VentureBeat: Google today launched Chrome 73 for Windows, Mac, and Linux. The release includes support for hardware media keys, PWAs and dark mode on Mac, and the usual slew of developer features. You can update to the latest version now using Chrome's built-in updater or download it directly from google.com/chrome. Chrome 73 supports Progressive Web Apps (PWAs) on macOS. These apps install and behave like native apps (they don't show the address bar or tabs). Google killed off Chrome apps last year and has been focusing on PWAs ever since. Adding Mac support means Chrome now supports PWAs on all desktop and mobile platforms: Windows, Mac, Linux, Chrome OS, Android, and iOS. Chrome now also supports dark mode on Apple's macOS; dark mode for Windows is on the way, the team promises.

The VentureBeat report includes a long list of developer features included in this release, as well as all the security fixes found by external researchers. Chrome 73 implements a total of 60 security fixes.

An anonymous reader quotes a report from Bleeping Computer: Microsoft has started to display notifications in the Windows 10 Action Center asking users to have a phone call with Microsoft developers and provide direct feedback about the ALT+TAB feature in Windows. While using a Windows 10 Insider build today, I was shown a Feedback Hub notification stating that "Microsoft wants to hear your opinions! To set up a phone call with Windows engineers, go to: http://www.aka.ms/alttab." This link then redirects to a web page at https://ux.microsoft.com/?AltTab. It is not known if this is only being shown to Windows Insiders users at this time.

When users visit this link they will be shown a Microsoft User Research page stating that a Windows 10 product team is looking to "understand our customer needs" and would like to have an anonymous 5-10 minute phone call with the user. In this particular case, the phone call will be with Microsoft engineers to discuss how users use the ALT+TAB feature to switch between apps. Microsoft states they are performing these calls in order to get a better understanding of how a feature is being used while they are in development. According to the web site, Windows engineers will be available on 3/11/2019 between 11:15 AM and 1:00 PM PST and on 3/12/2019 between 9:30 AM and 11:30 AM PST to schedule a call. The page goes on to say that users can expect a 5-10 minute call, but that it could last longer if there is more to discuss. They also state that the calls are not being recorded, are anonymous, and the content of the call will not be stored.

Version 6.50 of the PlayStation 4's firmware now allows you to remotely play your PS4 games from an iPhone or iPad. "To access it, you'll need to download the Remote Play app for your iOS device, and then pair it with your console," reports The Verge. "Compatible games can then be played over Wi-Fi using the on-screen buttons." From the report: Announced back in 2013, Remote Play originally let you stream games from a PS4 console to the handheld PlayStation Vita, but later in 2016, Sony released Remote Play apps for both Windows and Mac. Although Sony has yet to announce a broader Android version of the service, the existence of an Android version of the app that's exclusive to Sony Xperia phones suggests there aren't any technical barriers. Bringing the functionality to iOS is a huge expansion for Remote Play, although it's a shame that you're not officially able to pair a DualShock 4 controller with the app via Bluetooth for a more authentic experience (although some users have reported being able to get the controller working via a sneaky workaround). If you're prepared to use a non-Sony controller, then you'll be happy to know that MacStories is reporting that other MFi gamepads (such as the SteelSeries Nimbus) work just fine with the iOS app. Other limitations with the functionality are that you'll need an iPhone 7 or 6th-generation iPad or later to use it, and it's also only available over Wi-Fi. You can't use Remote Play from another location over a mobile network.

PS4 version 6.50 also adds the ability for you to remap the X and O buttons on the controller.

Google Maps is warning drivers in Canada as they approach some photo radar camera locations. "The feature, which is currently being rolled out by Google, allows users to see speed limits, speed cameras and mobile speed cameras on the map before they leave," reports HuffPost Canada. "It also gives a verbal warning -- an automated voice saying 'speed camera ahead' -- when drivers are near a fixed speed camera." From the report: Police in Calgary say the feature is useful to them. "The biggest thing we love ... is we place those (cameras) by collision statistics," said Sgt. Joerg Gottschling of the Calgary Police Service traffic section. "If we do a new site, if we are going to install a new camera, the next site is always selected by the next highest crash site. "Our intersection locations are all determined where we are trying to eliminate collisions."

Gottschling said they've had up to a 50 per cent reduction in collisions in some areas where those cameras are stationed. With Google Maps, he noted, all drivers approaching the fixed camera intersection get the warning. "That camera is only facing one way," said Gottschling. "Let's say it's only facing northbound, but you can approach southbound or eastbound ... you are still going to get Google telling you caution. "So you're going to go slowly and cautiously through there which, lo and behold, is actually what we want." Google said in an email that there will also be an ability for android users to report mobile speed cameras and stationary cameras.

An anonymous reader quotes a report from TechCrunch: Twitter today confirmed it's developing a new "Hide Tweet" feature, which it says will give users another option to protect their conversations. The option, spotted in Twitter's code, is available from a list of moderation choices that appear when you click the "Share" button on a tweet -- a button whose icon has also been given a refresh, it seems. Like it sounds, "Hide Tweet" functions as an alternative to muting or blocking a user, while still offering some control over a conversation. Related to this, an option to "View Hidden Tweets" was also found to be in the works. This allows a user to unhide those tweets that were previously hidden by the original poster.

Immediately, there were concerns that an option like this would allow users to silence their critics -- not just for themselves, as is possible today with muting and blocking -- but for anyone reading through a stream of Twitter Replies. Imagine, for example, if a controversial politician began to hide tweets they didn't like or those that contradicted an outrageous claim with a fact check, people said. It also requires the user to click to view the Replies that were hidden, which some users may not know to do and others may not bother to do. They may then miss out on an important point in the conversation, or a critical fact check. On the flip side, putting the original poster back in control of which Replies are visible may allow people to feel more comfortable with sharing on Twitter, which could impact user growth -- a number Twitter struggles with today. And it could encourage people to debate things with less vitriol, knowing that their nastier tweets could get hidden view. The "Hide Tweet" feature was first discovered by Jane Manchun Wong.

An anonymous reader quotes a report from CNET: Reddit is experimenting with tipping users, starting with the shittymorph subreddit, a group dedicated to the man who has memorably bamboozled many a reader with sneaky comments ending in a reference to a famous pro-wrestling match called Hell in a Cell. A Reddit admin with the username "internetmallcop" posted a thread on Tuesday announcing the experiment, calling it a "new feature to support u/shittymorph." Anyone in the group can now tip shittymorph for content he posts in his own subreddit.

A "tip" option appears below shittymorph's content. Clicking on it opens a window with suggested $3, $5 or $10 tips, or the choice to select another amount. You can input your credit card number directly into the window. The payments are handled by processor Stripe. Shittymorph responded to the admin post by saying he is "super grateful and honored" to be picked for the launch and beta testing. As of this writing Wednesday morning, the comment shows a $75.00 tip total in green above it. Internetmallcop explained in a comment how the tipping breaks out: "If you were to tip $100, about $78.5 goes to u/shittymorph, $18.5 to Reddit, and $3 to Stripe." It's unclear if Reddit plans to expand tipping beyond this experiment, and if it might extend to all users, or just certain content creators. As for why Shittymorph was chosen to test the feature, it "may be due in part to the Hell in a Cell writer's infamy and extensive fan base on the site," reports CNET. "Shittymorph's intriguing backstory to his creative Reddit comment efforts stem from the tragic loss of his father. He's also known for occasionally posting about his rescue dog Scooby."

An anonymous reader quotes a report from TechCrunch: Instagram is threatening to attack Pinterest just as it files to go public the same way the Facebook-owned app did to Snapchat. Code buried in Instagram for Android shows the company has prototyped an option to create public "Collections" to which multiple users can contribute. Instagram launched private Collections two years ago to let you Save and organize your favorite feed posts. But by allowing users to make Collections public, Instagram would become a direct competitor to Pinterest. Instagram public Collections could spark a new medium of content curation. People could use the feature to bundle together their favorite memes, travel destinations, fashion items, or art. That could cut down on unconsented content stealing that's caused backlash against meme "curators" like F*ckJerry by giving an alternative to screenshotting and reposting other people's stuff. Instead of just representing yourself with your own content, you could express your identity through the things you love -- even if you didn't photograph them yourself.

The "Make Collection Public" option was discovered by frequent TechCrunch tipster and reverse engineering specialist Jane Manchun Wong. It's not available to the public, but from the Instagram for Android code, she was able to generate a screenshot of the prototype. It shows the ability to toggle on public visibility for a Collection, and tag contributors who can also add to the Collection. Previously, Collections was always a private, solo feature for organizing your bookmarks gathered through the Instagaram Save feature Instagram launched in late 2016. Currently there's nothing in the Instagram code about users being able to follow each other's Collections, but that would seem like a logical and powerful next step.

LG's next upcoming flagship smartphone is the LG G8, which is expected to debut at Mobile World Congress at the end of the month. While much of the phone is similar to last year's model, LG yesterday announced some news on the phone's audio capabilities. "The phone uses the same 'Crystal Sound OLED' branding that LG has used on some of its TVs before; this means that the entire display will vibrate to work as a speaker, which was previously rumored," reports The Verge. "The news also confirms that the G8 will be the first flagship G-series phone not to use an LCD." From the report: The G8 still has a bottom-facing speaker for louder use cases like speakerphone calls, and LG says this can be paired with the top part of the screen for 2-channel stereo sound. Elsewhere, the signature quad DAC from LG's recent flagship phones returns -- which means there'll be a headphone jack -- as does the "Boombox Speaker" functionality that produces surprisingly bassy sound when the phone is placed on a table. LG has already confirmed that the G8 will have a front-facing 3D camera with a time-of-flight sensor, while rumors suggest there could be an optional second screen accessory.

Tesla CEO Elon Musk said his fleet of electric vehicles will be getting a "dog mode" to protect pets from overheating. The feature, which will be rolled out next week, will be able to detect when a pet is locked inside the car -- and keep the temperature at a safe level. The New Zealand Herald reports: There will also likely be a display or some form of communication to inform passers-by that the dog is safe. The feature was added after Musk was inundated with tweets from customers. In October, one Tesla driver asked him: "Can you put a dog mode on the Tesla Model 3. "Where the music plays and the air conditioning is on, with a display on screen saying 'I'm fine my owner will be right back?'" Musk replied: "Yes."

'Dog mode' will likely be an extension of Tesla's Cabin Overheat Protection System. This already prevents temperatures inside the car from reaching unsafe levels when kids or pets are inside. But the screen in Tesla models is likely to now flash a message to pedestrians informing them that the pet inside is safe. The "dog mode" update will be launched at the same time as a "sentry mode" -- designed to ward off would-be thieves. Sentry Mode will use the dashcam to record footage in the event of an attempted break-in. And it is rumored the car will play loud classical music through the stereo system to draw attention to the intruder and encourage passersby to call the police.

An anonymous reader quotes a report from ZDNet: After a year of secret preparations, Mozilla has publicly announced plans today to implement a "site isolation" feature, which works by splitting Firefox code in isolated OS processes, on a per-domain (site) basis. The concept behind this feature isn't new, as it's already present in Chrome, since May 2018. Currently, Firefox comes with one process for the browser's user interface, and a few (two to ten) processes for the Firefox code that renders the websites. With Project Fission (as this was named), Firefox split processes will change, and a separate one will be created for each website a user is accessing. This separation will be so fine-grained that just like in Chrome, if there's an iframe on the page, that iframe will receive its own process as well, helping protect users from threat actors that hide malicious code inside iframes (HTML elements that load other websites inside the current website). This is the same approach Chrome has taken with its "Site Isolation."

An anonymous reader quotes a report from Ars Technica: The next major Windows release, the Windows 10 April 2019 Update (codenamed 19H1), is going to offer some significant improvements [to error messages]. Microsoft described them on its Windows Insider webcast, and they were spotted initially by WinFuture. Currently, the best case during installation is something like this screen.

The message says that an incompatible application is detected, and a Knowledge Base article is referenced. It turns out that most Windows users don't know what "KBxxxxxxx" actually means, and the article isn't hyperlinked to make accessing it any easier. Issues detected through the other setup experience aren't much better. Windows will offer to uninstall problem applications, but often the better solution is to upgrade the application in question. The new setup process aims to be both more informative and more useful. The general approach is to allow decisions to be made within the setup program where possible and to put meaningful descriptions in the error messages, rather than leaving people with just a KB number to go on. Further, the "learn more" links will take you directly to the relevant Knowledge Base article, rather than hoping that end users know what "KBxxxxxxxx" means. Third-party developers will also be able to provide information about upgrades and updates when applicable to resolving compatibility issues.

While Gmail on the web was significantly redesigned last year, the app for Android and iOS stayed relatively unchanged, with the exception of an update last year that removed the bold colors in favor of an almost entirely white look. Engadget reports that a redesigned Gmail for mobile is starting to roll out today and it will be available to all Android and iOS users in the coming weeks. Engadget reports: Functionally, the new Gmail mobile app isn't wildly different than what came before. There's a button in the lower-right corner to compose a new email, just like before -- it's just white with a multi-colored "plus" sign, the same glyph that shows up in Gmail and Drive on the web. The iconic top red bar is now white, and the whole top area is a search bar; the old app required tapping a smaller target to get into search. Finally, there's a shortcut right to the account switcher on the main page. Previously, switching accounts required opening the sidebar, but now that option is front and center.

A few features that came to the web version of Gmail make their way to mobile today. Probably most recognizable is that attachment previews will show up below the messages, making it easier to both find messages with attachments and get a sense of the content. For those that prefer to see more messages, Google also has "comfortable" and "compact" density options that remove attachment previews and avatars, respectively. The large red phishing warnings that Gmail on the web shows also now show up in the app. Visually, it looks just like you'd expect if you've tried any of Google's recent mobile apps -- it's basically all white, with the new Google font throughout.

Spotify, one of the largest music streaming platforms available, is readying a "don't play this artist" feature in its apps that will let you mute artists you don't want to hear from. "The feature simply lets you block an entire artist from playing, so that songs from the artist will never play from a library, playlist, chart list, or even radio stations on Spotify," reports The Verge. From the report: The block feature works on songs by an individual artist, but it doesn't currently apply to tracks that an artist is featured on. Thurrott first spotted the feature, and notes that Spotify originally decided not to offer blocking "after serious consideration" back in 2017. Spotify has now reversed that decision.
