La Antártida pierde 40.000 millones de toneladas de hielo al año
Según un estudio de glaciólogos de la Universidad de California, Irvine; el Laboratorio de Propulsión a Chorro (JPL) de la NASA y la Universidad Utrecht de los Países Bajos, la Antártida pierde seis veces más hielo anualmente que hace 40 años. Concretamente, entre 1979 y 1990, la Antártida arrojó un promedio de 40 gigatoneladas de masa de hielo por año. (Un gigatón son mil millones de toneladas). De 2009 a 2017, se perdieron aproximadamente 252 gigatones por año...

China quiere montar una base lunar usando impresión 3D
China ahora se prepara para montar una base lunar internacional en la superficie de la Luna, porque al parecer haber alunizado en el lado oscuro al parecer no era suficiente. Pero si te preguntas cómo será posible que se construyan unas instalaciones en la Luna, pues te aseguro que no será transportando el material hasta nuestro satélite. El plan que tiene el gobierno chino para poder establecer la base lunar es bastante simple: Armar toda la base con tecnología de impresión 3D...

AMD President Says Its Next Epyc Server Processor Is the ‘Best the World Has Ever Seen’

AMD President Says Its Next Epyc Server Processor Is the ‘Best the World Has Ever Seen’
Advanced Micro Devices (AMD), under the direction of its President and CEO Lisa Su, garnered some big headlines in 2018 for both its technology advances as well as its growing stock price. Su gave an opening keynote at CES yesterday, first noting that AMD is marking its 50th anniversary. Su, who is a dynamic and enthusiastic public speaker, spent the lion’s share of her CES speech talking about gaming. And who can blame her? Videos depicting games like “Assassin’s Creed” and “Fnatic” captivated the audience. Eventually, she spoke about the (comparatively boring) topic of the company’s Epyc high-performance data center server processor...

A black hole the size of Jupiter is just wandering around the galaxy – Black holes come in all shapes and sizes
Black holes tend to come in two sizes: relatively small ones that form after a star collapses, and supermassive black holes that contain the mass of millions or billions of stars. Evidence for black holes that sit somewhere in the middle of that range has been scarce. Now, a new study has found ripples in an interstellar gas cloud that hint at the existence of an intermediate-mass black hole wandering through our galaxy...

In four years’ time, C will reach its 50th birthday, an anniversary also shared with PL/M and Prolog. Unlike those two, C remains immensely popular, it’s in the top ten of virtually every programming language popularity survey. Linux is mostly written in C. Python‘s CPython implementation, Perl, Matz’s Ruby, about half of R, the MyISAM code for MySQL and even the first Java compiler were all written in C. The kernels of most operating systems (including Windows, Mac, Linux, iOS and Android) all feature C...

Qualcomm Snapdragon 855 Benchmarks: Comparing the CPU, GPU, and AI Performance with the Kirin 980 and Snapdragon 845
2018 was an exciting year for smartphone enthusiasts. We saw the beginnings of nearly bezel-less designs, multi-camera innovations, computational photography techniques to make handheld long exposure practical, ridiculously fast wired charging, the reintroduction of wireless charging into the mainstream, and so much more. Android smartphones have so many features to differentiate them, but they’re all still powered by chipsets from either Qualcomm, HiSilicon, Samsung, or MediaTek. Most Android flagships in 2018 were powered by the Qualcomm Snapdragon 845, but in 2019 they’ll mostly be powered by the Qualcomm Snapdragon 855. Although the new Qualcomm mobile platform was announced back in December during the Snapdragon Tech Summit, Qualcomm waited until CES 2019 last week to let us benchmark the Snapdragon 855...

Imaging ever closer to the event horizon

Imaging ever closer to the event horizon
Two new papers probe the matter that's right on the edge of falling in. While black holes themselves swallow any light beyond their event horizon, the area outside the event horizon tends to emit lots of light. That's because the material falling in toward the black hole is extremely energetic as it sheds angular momentum and crashes into other material in orbit around the black hole. So, while we can't image a black hole directly, we can infer some things about its properties using light from the environment it creates...

Brightest quasar ever found shines with the intensity of 600 trillion Suns

Brightest quasar ever found shines with the intensity of 600 trillion Suns
From our point of view here on Earth, the brightest object in the sky is unquestionably the Sun. But this unremarkable star is a mere 10-watt bulb compared to quasars, extremely luminous galactic cores that shine so intensely thanks to their ravenous hunger for nearby material. Now, astronomers have detected the brightest quasar ever found, shining with the light of almost 600 trillion Suns. The quasar, officially designated J043947.08+163415.7, pips the previous brightness records by a fair margin. Until now the title belonged to a quasar shining with the equivalent of 420 trillion Suns, while the most luminous galaxy found so far is "only" as bright as 350 trillion...

Debian 10 Buster Enters Transition Freeze, New Theme Announced

Debian 10 Buster Enters Transition Freeze, New Theme Announced
Debian 10 "Buster" continues moving along for its hopeful stable release later in 2019. The first freeze is now underway while the new artwork/theme for Debian 10.0 has been decided. 12 January marked the transition freeze for Debian Buster. New transitions and big ticket changes are no longer permitted. Coming up next month on 12 February will be the soft freeze after which only "small, targeted fixes" will be allowed into the Buster archive. Finally, on 12 March is when the full freeze will take place for Buster. Once that full freeze is in place, changes need to be manually reviewed and approved by the release team. Details on the Buster freezes can be found here...

Team discovers new way supermassive black holes are ‘fed’

Team discovers new way supermassive black holes are 'fed'
Supermassive black holes weigh millions to billions times more than our sun and lie at the center of most galaxies. A supermassive black hole several million times the mass of the sun is situated in the heart of our very own Milky Way. Despite how commonplace supermassive black holes are, it remains unclear how they grow to such enormous proportions. Some black holes constantly swallow gas in their surroundings, some suddenly swallow whole stars. But neither theory independently explains how supermassive black holes can "switch on" so unexpectedly and keep growing so fast for a long period...

Big Bang query: Mapping how a mysterious liquid became all matter

Big Bang query: Mapping how a mysterious liquid became all matter
The leading theory about how the universe began is the Big Bang, which says that 14 billion years ago the universe existed as a singularity, a one-dimensional point, with a vast array of fundamental particles contained within it. Extremely high heat and energy caused it to inflate and then expand into the cosmos as we know it—and, the expansion continues to this day. The initial result of the Big Bang was an intensely hot and energetic liquid that existed for mere microseconds that was around 10 billion degrees Fahrenheit (5.5 billion Celsius). This liquid contained nothing less than the building blocks of all matter. As the universe cooled, the particles decayed or combined giving rise to... well, everything...

Epyc move: Supermicro plunges into Cascade Lake’s Optanical waters
In brief Supermicro is touting what's said to be the "first to market" Intel Cascade Lake AP Xeon server – and it's fitted with Optane DIMM modules to make in-memory apps, particularly the AI ones, run faster. Although the Silicon Valley kitmaker claims this month that it is first on the block with this grade of gear, it's not on general sale. For one thing, the processor isn't widely available yet. So, y'know, you'll probably have to take a ticket and get in line for one of these machines...
