    Question Am I technically a German citizen?

    Well, if you 'can claim a status' it usually implies that you can also opt to 'not claim the status':) Otherwise the 'can' is a bit misplaced. Of course not - laws never work like that. If an Austrian citizen commits a crime online that's relevant inside the US, the US will potentially convict...

    Question Am I technically a German citizen?

    Not sure why you read that in the Wiki snippet, as it emphasizes the action you have to take two times: Those born before 1 January 1975 could normally only claim German citizenship from the father and not the mother. Exceptions included cases where the parents were unmarried (in which case...

    Question Am I technically a German citizen?

    Trying to check Austria, it doesn't seem to be written into the passport at all on the sample passport images I could find online (which makes sense, because it already says so on the cover page). Switzerland actually prints the country name on them, but I can't make out on the online images...

    Question Am I technically a German citizen?

    Well, a newborn child has to be registered, it's at this stage the citizenship is done. I gather it happens easier if the child is actually born in Germany, for our kids born in Finland we had to translate the Finnish birth certificate and hand that in with the application. There's generally no...

    Question Am I technically a German citizen?

    As such, it does not seem outrageous, generally the laws in that respect were pretty open with regard to pre-war German communities in 'lost' territories wishing to live in Germany, so it is indeed traced through ancestry rather than place of birth or living. However, I strongly suspect you're...

    News COVID-19 pandemic

    I'm going to go with that one:lol: Given how easily journalists are willing to kick out math to get scary headlines, it's only a question till that spreads. And without math, civilization will not do well. Actually, if I have done my research right, 2% would be on par with the Spanish Flu...

    SDK Question Control Surface Moments

    Are you by any chance mixing a lift/drag with an axial/normal force coordinate system? They would agree at zero AoA and be quite different at high AoA. Just a wild stab...

    Updates Boeing's CST-100 Starliner

    You ask Cortana or Siri of course :lol: Personally, I go with the 'dumb' scheme by the clock rather than the AI-type scheme which tries to be situationally aware by itself - there's far more potential for things to go wrong in the smart computer than in the dumb one.

    Making Movies

    Since I did lots of drone flights for the movies and only a small fraction of the material is actually going to be used for the Clíodhna series, we decided to make a composition from the material - 'Dreams of Autumn' "Dreams of Autumn" So that's how central Finland looks like in fall :) Enjoy!

    News The Space Shuttle for Flightgear 3.6

    I'm happy to announce that the next milestone of the Shuttle is tagged and will soon be widely available via the standard FG download option. There's quite some work under the hood, but the big new thing is the option to grapple payloads (or push them away if you're not careful...). Also...

    News The Space Shuttle for Flightgear 3.6

    A genuinely different perspective for a change. In reality, the Shuttle has often been escorted by fighter jets in its last flight phase - so I've wondered how it looks from the cockpit of such a jet. To re-create the experience, I recorded a Shuttle TAEM trajectory to Edwards AFB, fed that to...

    News The Space Shuttle for Flightgear 3.6

    Finally getting the CAM matrix voting problem under control - here's GPC 2 after failing to sync with the redundant set (on orbit here being composed of 1-3) in step 2 - in step 1 it votes against 1 and 3, but then in step 2 the algorithm decides that as a minority being voted out, it can't vote...

    LEO targeting - a numerical tool for orbital maneuvering planning

    GinGin tested a workflow to apply the tool to solve de-orbit problems in Orbiter, and found that using a position (rather than state_vector) declaration is easiest. Unfortunately by mistake the mission elapsed time (MET) could not be set properly when using this way of init, so I made a 0.42...

    SSU Tutorials

    I'm not sure what 'that' refers to - an example for optimizing a PEG-4 de-orbit burn is given on the page I linked. An example for a pocket formula GinGin has sort of given. That's trivial, because it's completely independent of the targeting which only produces retrograde and radial DV...

    SSU Tutorials

    If a commandline tool is enough, may I recommend LEO targeting? It actually can optimize given a PEG-4 constraint for the entry interface and the desired range - among other things, I wrote the tool for precisely that purpose. And it's GPL licensed, so you can modify it to your needs... (In...

    Relativistic large-scale collisions

    I think you can pretty much de-mystify the problem by considering energy-momentum conservation and the rest mass vs. relativistic mass. A relativistic asteroid will have a much higher mass (and momentum) due to relativistic effects when seen from the near-static target than its restmass would...

    News The Space Shuttle for Flightgear 3.6

    In case you were wondering - development is still happening:) Currently I'm busy to enable the cue card binders to be usable in the cockpit - right now you can attach some systems procedure binders to the velcro and browse through them - because that might be awkward in a stress situation, each...

    Payload procedures

    I'm currently busying myself coding Shuttle-payload interactions, and I was wondering if anyone could recommend a good read to brush up on procedures and data. For instance, I was wondering about questions like * I have satellite which is supposed to be captured into the payload bay - but it...
