Gears of war: When mechanical analog computers ruled the waves

In some ways, the Navy’s latest computers fall short of the power of 1930s tech.

We are resurfacing this feature from 2014 for your reading pleasure on this holiday weekend.

The USS Zumwalt, the latest destroyer now undergoing acceptance trials, comes with a new type of naval artillery: the Advanced Gun System (AGS). The automated AGS can fire 10 rocket-assisted, precision-guided projectiles per minute at targets over 100 miles away.

Those projectiles use GPS and inertial guidance to improve the gun’s accuracy to a 50 meter (164 feet) circle of probable error—meaning that half of its GPS-guided shells will fall within that distance from the target. But take away the fancy GPS shells, and the AGS and its digital fire control system are no more accurate than mechanical analog technology that is nearly a century old.

On the Moon, astronaut pee will be a hot commodity

Urine can be used for landing pads, gardens, and drinking water.

Ever since President Donald Trump directed NASA to get boots on the Moon by 2024, the agency and its partners have been hard at work trying to make it happen. Late last month, NASA awarded contracts to three companies to develop a crewed lunar lander, but getting to the Moon is just the start. The agency also plans to build a permanent Moon basebefore the end of the decade and use it as a stepping stone to Mars.

If astronauts are going to spend weeks at a time on the Moon, they’re going to have to figure out how to live off the land—er, regolith. It’s too expensive to ship everything from Earth, which means they’ll have to get creative with the limited resources on the lunar surface. Moon dirt is a great building material and there’s water in the form of ice at the south pole that can be turned into rocket fuel. But the hottest commodity of them all may very well turn out to be an astronaut’s own pee.

Earlier this year, a team of European researchers demonstrated that urea, the second-most common compound in human urine after water, can be mixed with Moon dirt and used for construction. The resulting material is a geopolymer, which has similar properties to concrete and could potentially be used to build landing pads, habitats, and other structures on the Moon.

Elektro-Pickup: Tesla schrumpft den Cybertruck doch nicht

Der Cybertruck wird doch nicht verkleinert. Das hat Elon Musk zusammen mit Chefdesigner Franz von Holzhausen entschieden. Trotzdem könnte es ein kleineres Modell geben. (Tesla, Technologie)

Spotify Launches Crackdown on Tools Offering Premium Service For Free

Spotify has filed a wave of DMCA takedown notices with Google in an effort to remove links to software claiming to offer a premium experience without paying. In many of its complaints Spotify warns that the company believes that the tools are intended to be used as “instruments of fraud”.

From: TF, for the latest news on copyright battles, piracy and more.

Spotify is currently the most popular music streaming platform in the world with 286 million users. An impressive 130 million subscribe to the company’s premium service with the remainder using the ad-supported tier.

Somewhere in those figures are a small minority who enjoy the features of Spotify Premium but yet manage to do so without paying the subscription fees charged by the company. This is achieved by deploying various hacks and workarounds that remove the restrictions imposed on users of the ad-supported service.

In many cases this means users obtaining a hacked variant of the Spotify software, often on the Android platform. These applications don’t subject users to adverts and in some cases claim to enable other features such as unlimited track skipping and a departure from enforced shuffling.

Needless to say, Spotify views these applications as a threat to its business model. The company has previously taken action against specific tools in an effort to make them harder to find but more recently the Swedish streaming service appears to have stepped up its efforts.

Beginning back in March but increasing as the weeks have passed, Spotify AB has been sending DMCA notices to Google targeting domains that appear to be offering the types of tools highlighted above. Torrentfreak learned of the complaints from a third-party and we were able to track many of them down using the Lumen Database repository.

The majority targeted at Google’s search indexes contain similar wording, with claims that the domains in question are infringing on Spotify’s intellectual property rights. However, the company goes further still with allegations that the tools are designed for fraudulent purposes.

“This site uses Spotify intellectual property in its content without authorization and this falsely suggests Spotify sponsorship or endorsement of the website and violates Spotify exclusive rights,” many read.

“We reasonably believe that it is the intention of its owners to use it as an instrument of fraud.”

Spotify DMCA complaint to Google

At the time of writing Spotify has targeted at least 20 domains with requests like this one to remove more than 60 URLs. Many seem to be so-called APK download sites or similar platforms giving hints and tips about how to obtain Spotify and indeed other services for free, with accompanying links.

However, when testing the domains in the numerous takedown notices our interest was piqued by at least one that triggered a Malwarebytes ‘fraud’ alert. Spotify took a particular interest in this domain by targeting 14 of its URLs, which raises the question of what type of fraud is taking place on the site.

SpotifyPlus.com blocked

Spotify appears to use the term in connection with using its intellectual property and accessing its platform in an unauthorized manner but it wouldn’t be a huge stretch to think that something even more nefarious might be at play with some modified APK files available online today.

In the vast majority of cases, Google has complied by delisting the requested URLs. At the time of writing there are a handful of more recent Spotify complaints marked as pending a decision (1,2,3)but it would be no surprise if they were removed during the days to come.
