    O(Log N)

    With an N of any meaningful size (say 100000) then adding 1 more to N is so close to free that it might as well be free. Right?

    We have to square N to double the runtime, and then square it again to double it again. 2^8 becomes 2^16 becomes 2^32 becomes 2^64.

    If you can do 2**8 items in real-time today, then in ~5 years you can do 2**64 items in real-time on the newer hardware. Thats why O(Log N) is fucking unlimited.

    Still no reason to call it "unlimited."

    Its because beyond a certain size of N, any increase in N that does not already hit non-computational constraints (memory limits, the word size of the architecture, etc) becomes essentially free from a computational perspective. When doubling N from 1 Billion to 2 Billion items only increases the workload by 3.33%.. THATS FUCKING UNLIMITED

    They did mention medical imaging, which is a nearly 100% voxel based market...

    So like ray-tracing their renderer would begin "for each pixel..."

    One of the benefits of raytracing is that it does scale extremely well with the amount of scene geometry. Essentially, doubling the amount of geometry only adds 1 more iteration to hit testing. O(PR log N) where P is the number of pixels, R is the number of rays per pixel, and N is total amount of geometry in the scene. It is this scaling that means that if geometry continues to increase in complexity, raytracing will eventually overtake rasterization in raw performance.

    Raytracing is like QuickSort() and Rasterization is like BubbleSort() .. for small N the BubbleSort() beats QuickSort() because it has a smaller constant. In the case of Raytracing vs Rasterization, Rasterization has very small constants compared to raytracing so Raytracing doesnt overtake Rasterization until N is very large (Intel had put out an estimate several years ago.. determining that the N where raytracing overtakes rasterization in raw performance is somewhere between 1 million and 10 million polygons)

    Now these guys just seem to be doing Raycasting (ala medical imaging), rather than Raytracing, so the N where this happens would be quite a bit smaller.

    We know from recent events that the House has unquestionably the most control of both Taxing and Spending. With that in mind, the Democrats controlled the House from 1949 to 1995.

Companies like IBM surrounded things like arithmetic coding (used in both codecs) with patents on efficient methods fairly early on, and while those initial patents are now out of scope, new technologies created new opportunities for new efficient methods that again were patented.

    The issue isnt File System corruption.. when the issue happens, the machine simply can no longer detect the drives no matter what you do. Its not simply data loss.. complete loss of any access to the device.

My theory is this second alternative, that its Block System (not the same as the File System!
