Comment Domain Knowledge is Key (Score 1) 178

Take a job doing practically anything - then intensely observe every piece of software and hardware infrastructure in use, and what is and isn't working. covertly Interrogate coworkers, supervision, management, and build that mental model and the lexicon of the line of business. Then turn your resume upside down, mentioning all those 'keywords', and be upfront if it's superficial ( or not ). Don't remove the degree, delegate it to the 'education section at the bottom, and instead decompose it into a list task oriented experience, skill, and knowledge. Those are the hooks folks are looking for. Then send it to other firms in the same domain / value network. But more importantly, if you are haired into any sizeable company, they have internal job postings, and preferentially hire existing quality folks. Hiring outsiders from the public pool is a huge risk for any corporation versus someone that's already on the payroll and has some track record and has folks around them that the hiring manager can conversate with. The employment game is just another algorithm.

Myth. See 'US Spy Satellites at Diffraction Limit for Resolution Since 1971' at https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.nextbigfuture.com%2F... ..."A perfect 2.4-meter mirror observing in the visual (i.e. at a wavelength of 500 nm) has a diffraction-limited resolution of around 0.05 arcsec, which from an orbital altitude of 250 km corresponds to a ground sample distance of 0.06 m (6 cm, 2.4 inches). Operational resolution should be worse due to effects of the atmospheric turbulence. Astronomer Clifford Stoll estimates that such a telescope could resolve up to “a couple inches. Not quite good enough to recognize a face”

The NGA has declassified much of the spy satellite imagery ( film ) from that era, see GAMBIT-HEXAGON Images at https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.nro.gov%2FAbout-NRO%2F...

The operative word there is 'pathfinder', these missions were never meant to be ongoing, they were to prototype follow on design and deployment with more robust observation capabilities. The mission is redundant, technology and operations have improved. NASA, ESA, JAXA, and others share platforms and instruments, so the question really is not about a particular satelite but if the actual capability is lost, and it is not: "... the biggest change will result from data delivered by the upcoming Copernicus CO2 Monitoring Mission (CO2M)42 that is due for launch in 2025.

Comment Fee funded (Score 2) 52

For Traffic Coordination System for Space (TraCSS) to be sustainable long term and not vulnerable to political whims, the funding should be analogous to how aviation works ( like landing fees, gate slot rental, etc. ) which are aligned and proportional to the benefit received. Spread over the entire orbital industry, that amount of money is trivial to players like SpaceX, Amazon, etc. Really no different than tech companies contribution to Open Source software projects for building and maintaining common infrastructure.

Comment Nothing 'new' about hexagons (Score 1) 30

'Zip Codes' are not actually 'areas', they are basically a contrivance, a polygon that encloses a collection of 'Letter Carrier Routes' ( https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.marketmaps.com%2Fcar... ). Those Routes are optimized for all the standard logistics concerns, volume, number of end points, street network access, etc. Individual buildings can and often do have their own ZIP codes, especially in areas with high-volume businesses or institutions. Any reference scheme based on equal sized polygons is a mismatch to the variability in feature density, so there is a type of fractal hexagon mapping, Discrete Global Grids which can basically address any resolution and density of data ( https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.sciencedirect.com%2F... ).

Comment Re:I'm surprised (Score 1) 30

The Earth's direct gravitational effect isn't the only relativistic effect, the aspect that it is also rotating injects some interesting weirdness.

https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.gpsworld.com%2Finsid...

"There is more to relativity than the special theory and general theory. There is the Sagnac effect associated with our rotating reference frames attached to Earth, in which we’d like to determine a position. The principle of constancy of the speed of light cannot be applied in a rotating reference frame, where the paths of the radio rays are not straight lines, but spirals. (Receivers at rest on Earth are moving quite rapidly: 465 meters per second at the equator.) There is also the Shapiro delay associated with the slowing of electromagnetic waves as they near Earth, which amounts to a fraction of a nanosecond. "

Comment Since Evans & Sutherland (Score 1) 65

The vertical markets for AR/VR which actually have an ROI on the premium cost have been the same ones since the late 1960s ( first full motion simulators from Evans & Sutherland, for example ) with one exception in the consumer space, gaming. And they saturate fairly quickly, especially since the display devices are actually a small part of the investment required for an actually useful application in the real world. They never 'cross the Chasm' so to speak despite the hopes of hypsters. I've been doing 3D solid modeling and simulation since the 1980's in the manufacturing vertical and the current VR/AR hypists have no idea how difficult it is to produce and harmonize the assets within a fairly narrow boundary ( one could also probably ask a Hollywood movie production team or game developer business ). It is hard in manufacturing where everyone is trying like hell to cooperate, most likely impossible with competing players all pushing their own proprietary interests to create walled gardens ( one of the AR/VR headset vendors actually required on to have and use a FaceBook account ).

Comment Re:Natural Sources? (Score 1) 66

"Analysis of physicochemical processes in volcanic column showed the possibility of formation of the following types of black carbon particles: single highly dispersed particles or their small fractal aggregates, particles of fibrous or encapsulate types associated with pyroclasts, graphite-like pyrocarbon particles.Moreover, the formation of particles of the second and third types is energetically more accessible than that of the first type. Data on the detection of carbonceous particles in the stratosphere and volcanic ash confirm the possibility of formation of all types of predicted particles and their identity with particles produced by known technological processes and detected after powerful volcanic eruptions in Kamchatka (Russia). The main limiting factors determining both the possibility and the lower boundary of the conditions for the formation of particles of different types have been identified: temperature and concentration of carbon-bearing gases in the volcanic column."

Comment Climate Theater Ext-Gen-Sto-Dis-Use (Score 1) 522

EV's are an ideological prop for climate theater, and literally putting the cart before the horse. From a systems engineering view, fossil fuels are not equivalent to electricity through the entire logistics train from extraction (a coal seam or windy ridge ), generation ( converting that source usable form of power ( electricity or gasoline ), storing that to level supply and demand cycles at al scales, distributing and dividing it to supply end points ( transmission lines, pipelines, etc. ), and only then the actual end use ( commuting by car, moving a load of cargo, etc. ). Every useable form of energy is actually performing all these functions in parallel along that chain, not just when it combusts or rotates at the point of use. Any improvements would need to be addressed at each link upstream, and some provide vastly more bang for the buck than others - but explaining complicated stuff to the public is complicated, but people think they understand what a car is, so distract attention from the stuff that really matters, that which requires math and hard decisions. But especially stupid is increasing a heavy, highly variable demand that can't be uniformly provisioned at the end of that function change - an analogy would be plugging every home appliance into one socket. The personal EV is just a single narrow use case geographically concentrated, and represented low-hanging fruit, and is at the edge of the Chasm Crossing.

Included among the last-mentioned of this eclectic band was a somewhat obscure 46-year-old émigré journalist Karl Marx, who would soon come to play a decisive role in the organization." Basically their agenda is propagating the benefits of authoritarian socialist regimes like the USSR, North Korea, and the PRC ... and the non-existent 'workers' rights under their lash.
