Active Volcano Found Under Antarctic Ice: Eruption Could Raise Sea Levels

Inevitable eruption will speed up ice loss on frozen continent, study says.

A newly discovered volcano found buried beneath a thick layer of ice in Antarctica could speed up ice loss and raise global sea levels when it erupts, scientists say.

The finding, detailed in the current issue of Nature Geoscience, marks the first time that an active volcano has been discovered under the ice of the frozen continent. (Also see "Giant Undersea Volcanoes Found Off Antarctica.")

When it erupts?which no one can predict?the volcano "will create millions of gallons of water beneath the ice?many lakes full," study leader Doug Wiens, professor of earth and planetary science at Washington University in St. Louis, said in a statement.

This water will rush beneath the ice toward the sea and feed into one of the major ice streams that drain ice from Antarctica into the Ross Ice Shelf, Wiens explained.

      Lava launches a customizable smartphone in India
      by Rajesh Pandey

      Lava, once a major player in the Indian smartphone market, has made a comeback in the country with its new MyZ and Zup series of customizable phones. These phones are 'Made in India' and can be customized by the customer as per their liking. Both smartphones are budget-oriented, with customization being their key highlight.

      The Lava MyZ features a 20:9 aspect ratio 6.5-inch HD+ IPS display which is protected by Corning Gorilla Glass 3. It is powered by a MediaTek Helio G35 octa-core chip that's paired with 5,000Ah battery, dual-4G connectivity, USB-C, and more.

      As for the customizability part, Lava is allowing customers to decide the camera, RAM, and storage configuration of the device as per their liking. The base variant features 2GB RAM and runs on Android Go, though customers have the option of bumping the RAM to up to 6GB in which case the device will run the regular version of Android. The rear camera can be customized with a 13+2MP setup or a triple-camera setup comprising of a 13MP primary shooter, 5MP ultra-wide, and 2MP depth. For the front camera, customers have the option of selecting between an 8MP and 16MP sensor. You can customize the MyZ as per your liking from Lava's online store.

      There's also the Zup series of smartphones which features the Z2, Z4, and Z6. These phones are basically the same as the MyZ and come with different camera, RAM, and storage configurations. Interestingly, Lava is allowing Zup smartphone owners to take their device to a service center within a year of purchase and upgrade its RAM or storage space for a price.

      Linux Mint is working on a new tool called Web App Manager
      by Paul Hill

      In its monthly update, the Linux Mint project announced that it’s working on a new app called Web App Manager that’ll let users turn their favourite websites into stand-alone applications that can be found in the start menu and be pinned to the taskbar. The Mint team is developing the tool in collaboration with the Peppermint OS team which has built a similar tool before.

      As things stand right now, the Peppermint team has a tool called ICE that lets you turn websites into web apps. In a thread on GitHub, the head of Linux Mint, Clem Lefebvre suggests that the ICE back-end be separated from the interface so that the Mint team and Peppermint team can use their own respective interface. This plan isn’t definite yet but has been suggested.

      Gallery: Web App Manager
      According to the images that have been made available, users will be presented with a list of web apps that they have already created. Users can remove and edit these or add a new web app. When creating a new web app, users will need to supply the app’s name, web address, an icon, which category it should be included in on the menu, which browser it should open in, and there’s a toggle to hide the browser's navigation bar.

      Another nice aspect to these web apps is that they’re created with their own browser profile and appear in their own window. Not only does this give users help to separate their general browsing from their web app browsing but it also makes switching between apps on the Alt-tab selector a bit easier.

      The Web App Manager is currently available for download but keep in mind that it is beta quality and isn’t fully translated. Around November or December when Linux Mint 20.1 launches, the new Web App Manager will probably be included.

      A majority of Microsoft employees want to continue working with ICE, as per a recent survey
      by Hamza Jawad

      A couple of weeks ago, The New York Times unveiled an open letter posted on Microsoft's internal message board, signed by over 300 employees, that denounced the company's work with the U.S. Immigration and Customs Enforcement (ICE). Now, a recent survey conducted by TeamBlind shows that a majority of Microsoft employees that took part in the survey are content with collaboration between the tech giant and the law enforcement agency.

      A total of 1,180 Microsoft employees participated in the survey that ran from June 20 through June 28. The picture below shows the exact breakdown of how they responded to the question being asked.

      As can be observed by compiling the percentages of people who chose option A or option C, 44.32% of the employees who took part in this survey want the company to either revise the conditions of its contracts with the ICE, or end them altogether. The remaining 55.68% are content with some form of collaboration with the law enforcement agency.

      Interestingly, of the total 5,166 Blind app users who took part in the survey, around 57% want the tech giant to end or alter its contracts with the ICE, with only 43% being content with the current agreements in place. This implies that the general public is not in favor of Microsoft associating itself with the immigration agency, at least in the way it currently is doing so.

      Microsoft has faced severe backlash following the continuance of its work with the ICE in the past few weeks. The Trump administration's decision to enact a policy that led to about 2,000 children of illegal immigrants being separated from their families at the U.S.-Mexico border last month sparked major controversy. Microsoft's existing contract with ICE - which was initially largely ignored - led to the tech giant being caught in the crossfire, although the company insisted that it was not working "on any projects related to separating children from their families at the border".

      It should be noted that with the tech giant currently employing over 120,000 people, this survey that undertakes the views of less than 1% of its total workforce is not enough to gauge the overall feeling among all employees. However, considering that only around 22% of those involved in this survey want to completely stop working with the ICE, it can perhaps be said that a majority of the firm's total workforce would not have a drastically different view on the matter.

      Microsoft says it's 'dismayed' at the separation of children following ICE contract backlash
      by Muhammad Jarir Kanji

      Microsoft has come under a great degree of scrutiny in recent days regarding its work with U.S. Immigration and Customs Enforcement (ICE), which was first announced in January. While the contract was largely ignored initially, recent policy decisions by the Trump administration regarding immigration have fomented considerable discontent both within the company and without.

      The Trump administration this week enacted a policy that would separate the children of illegal immigrants at the border from their families, generating much controversy. This, along with the purported living conditions of the children, have turned into a massive political debate within the U.S., and Microsoft seems to have been unwittingly caught in the crossfire.

      Firstly, the company has faced severe backlash on social media from groups disagreeing with the policy. In response, the company has issued a statement suggesting it disagreed with the recent policy initiative by Attorney General Jeff Sessions, claiming,

      Without clarifying the exact details of the work Microsoft is doing for ICE, and what manner of computation the company's Azure cloud computing platform is providing for the government agency, Microsoft did clarify that it was not working "on any projects related to separating children from their families at the border", and that it was "not aware of Azure or Azure services being used for this purpose."

      Microsoft certainly seems to have been caught off-guard with this development, as the company even temporarily pulled the section pertaining to ICE from its January blog post, before blaming the change on a mistake by an employee and reinstating it.

      Tensions within the company have gone beyond just an uncoordinated response, however, as Gizmodo reports multiple employees within the company have also shown their vexation at the Microsoft's work with the embattled immigration agency.

      GoPro films being swallowed up by lava and survives
      by Richard Tyr Blewitt

      Erik Storm was busy telling his tour group a story when he suddenly remembered that he had left his GoPro in the path of some lava that was creeping its way into a small crack in the ground. By the time he had got to his camera the lava had already engulfed it, but he quickly managed to fish it out of the liquid rock using a hammer.

      Upon his return home, he began chipping away at the now cooled lava that encased the camera. To his surprise, as he freed it, he noticed the Wi-Fi light was still blinking. Miraculously the camera had survived, the camera's SD card still worked, it held the recording of the whole ordeal, and Erik was still able to use the camera. Although he says it didn't work quite as well as before, which can be expected as the camera resembled a horribly burnt lasagna once it came out of the lava.

      As can be seen in the above video, the camera managed to record the slow crawl of the lava right up until the camera itself eventually burst into flames and was consumed in molten rock.

      GoPro, the company, has been going through a number of difficulties in recent years. It has begun to experiment with new types of products, and even though the camera in this instance did have an additional protective casing this feat is nonetheless something which shows the robustness of its famous action cameras.
