    Yeah, it seems it's not permanent. You can go here: https://neo.gsfc.nasa.gov/view.php?datasetId=VIIRS_543D&date... and then click on the right side "0.25 degrees 1440 x 720".

    Indeed Bizum is almost default now here in Spain, and for instance the equivalent in Sweden, Swish, is also almost default there. Went trekking into a national park, and the ranger…

    This is exactly how we implemented eIDAS in Spain. The government-issued national ID (DNIe) is an ISO 7816-compliant smart card. Latest versions are also ISO 14443-compliant for co…

    I talked with one of the aeroacoustic engineers working on it, she says they expect to match noise levels of current engines.

    Damn. I especially liked the cloud backup & sync. Any good alternatives?

    I don't know about the A320 but this was certainly the model for the Eurofighter. One of my university professors was in one of the teams, they were given the specs and not allowed…

    Lenovo has been doing this in Spain for quite a bit, and you can even buy them without any preinstalled OS at all for a lower price still. But at least here the option is typically…

    It's tangential, but this is the first time I've seen Fluent installed by simply decompressing a tar, instead of executing their big installer.

    In reality few codes are capable of effectively parallelizing to so many computing processes. But, how cool would it be?

    It really depends on the problem to be solved (domain size, complexity of physical phenomena such as turbulence model, heat transfer, acoustics, multiphase flows, combustion, etc.,…

    Oh no, apologies if that was the impression I gave!! I actually perform CFD simulations in HPC clusters, and in fact I'm an admin of the small cluster at my research institute =) T…

    It is difficult, but there are modeling approaches that work, such as VoF ( https://en.wikipedia.org/wiki/Volume_of_fluid_method ). Basically, in addition to velocity, pressure, te…

    There's also the issue of ingesting the turbulent/detached boundary layer of the fuselage at high angles of attack, causing inlet distortions and the corresponding risk of compress…

    Maybe also a "Twain-version" of the title of Farley Mowat's novel The Boat Who Wouldn't Float ?

    Research-grade acoustic cameras from the leading providers cost anywhere from 50k-150k€. But they have much more than the "four microphones" the article cites, so I don't know whic…

    Yes, this is no-cost but not necessarily open source. NASA open source software can be found at: https://code.nasa.gov/
