Brief information: Java use, LG smartphones, hydrogen, Mars rovers

The online giant Google has fended off a billion-dollar lawsuit by the software company Oracle for alleged copyright infringement in the Android smartphone system before the US Supreme Court. Google had used approximately 11,000 lines of Java programming language software code for Android. The Supreme Court ruled in Washington on Monday that Google had not committed any violations of the law and thus overruled a judgment from the lower court. Lawyers and open source developers had eagerly awaited the vote, because a victory for Oracle would have had far-reaching consequences for the copyright and licensing of APIs.

The mobile phone division of the Korean technology company LG Electronics has been making losses for years. Now LG is pulling the rip cord and closing the line of business, said LG’s board of directors on Monday. Both at national and international level, the competition is too powerful. Instead, the South Korean electronics manufacturer wants to focus on other business areas, such as vehicle electronics, smart homes, robotics, artificial intelligence and B2B platforms.

Hydrogen as a drive for cars and trucks on German roads will be indispensable in the coming decades, according to Veronika Grimm. “It is utopian to believe that battery-supported electromobility will be the only solution,” said the Nuremberg economics professor, who is also the head of the Bavarian Hydrogen Center, of the dpa news agency. Particularly in heavy goods traffic, hydrogen technology can be used efficiently at a comparatively early stage, said Grimm.

The Ingenuity helicopter survived the extreme sub-zero temperatures on its first night without the heating of the Mars rover Perseverance. This was announced by the US space agency NASA and once again reminded that the temperatures at the location of the two devices can drop to -90 degrees Celsius. This could damage electrical components, including the batteries that keep the small helicopter working. The fact that Ingenuity managed to survive on Mars on its own is another milestone on the way to the historic first flight over Mars, which is scheduled for April 11th.
