   Hi Todd! Our recent work implements a subset of GraphBLAS operations for GPU and compares them to Gunrock in breadth-first-search [1]. Our implementation of a subset of GraphBLAS is comparable to Gunrock performance for power law graphs, bu

   I like how your post differs from the pessimism of most HN posts when it comes to politics, and how you have a well thought-out strategy i.e. put the emphasis on explicit public goods and for things. Do you have any other examples aside fro

   Depends on what you mean by "traditional". Even in the New Testament, you'll find passages like 2 Thessalonians 3:10: 'For even when we were with you, we gave you this rule: "The one who is unwilling to work shall n

   GraphBLAS is an open standard, and I believe the implementation in the link provided targets single-threaded CPU, which rules it out for comparison with nvgraph, custinger and gunrock. My recent work actually implements some GraphBLAS opera

   Agreed. It blew my mind to learn that tiling matrix multiplication is more efficient than untiled, but that you can only show tiled is faster in a hierarchical memory model (for tiled, you have arithmetic intensity that scales with size of

   Yeah, it seems a common trope in western culture. In the Iliad , Agamemnon leader of the Greeks does not get favourable wind that is needed for his armada to sail to Troy before he sacrifices his daughter who he loved.

   Thank you for this video. The anecdotes about Obama and the German finance minister are excellent!

   I think the idea is they get an acturay to estimate how many rooms will be empty at some future date, and sell the room-nights they estimate they couldn't fill anyways to 3rd party channels. This way, they at least recoup some money on

   This makes sense. They should add a NN feature called farm priority ranked from 1 to 5 (similar to the one humans use) with 1 being carry, 5 being support, and each taking progressively less farm and lower priority taking Aegis. They could

    This is something I've always wondered: Are treasury bond ladders strictly better than an equivalent treasury bond fund (say VFITX), because the interest rate risk can cause the bond fund to lose value while the treasury bond ladder

    I liked the Steve Eisman character from The Big Short, but I was disappointed his prediction bank stocks would do well didn't play out. KBE: 44.49 Jan 30, 2017, 47.82 July 11, 2018 = 7.48% price growth (I couldn't find numbe

    Can you list some economists that agree with Trump something should be done about China? Most economists I've heard suggests the opposite, so a citation would be great.

    You are correct only if all else is the same. However, I take issue with the assumption that you can leave all else the same. The net force on a heavier object is a higher for the lead ball than for the wood ball. The net force for the lead

    This doesn't sound correct to me. The acceleration due to gravity is the same on both balls. However, since the lead ball weighs more than the wood ball, the force of gravity on the lead ball is stronger than the force on the wood ball

    Thank you for sharing. One thing that impressed me about Hamming's essay on how to produce world-class research [1] is that it suggests a necessary, but not sufficient prerequisite is to spend your waking life thinking hard about some

    This is an interesting perspective, because in his book, "The History of Western Philosophy" recommended elsewhere in this thread, Bertrand Russell makes this one of the metrics by which he rates historical philosophers. For examp

    One way to test this would be to use a scoop that's 2x bigger than the other scoop, and putting in 3 scoops using the smaller scoop vs. 2 scoops of the bigger scoop.
