HN discussionIf this were true, there would be much more P2P networks today than fifteen years ago, but that’s not the case. According to [1], in 2004 BitTorrent accounted "from 20 to 35% of all traffic on the Internet". At that time the bandwidth cost was at least two orders of magnitude higher than today. The price of hard drive has since been divided by 40 [2] and the total Internet traffic has been multiplied by 40 [3]. [1]:…

HN discussionThis isn't directly related, but is hadoop the only java-based solution to parallel computing? I've seen some examples of people attempting to do work in java mpi[0] again. It seems like dealing with the gc and memory management in general has been an issue when trying to do high performance computing in java, especially at a distributed scale. 0: http://blogs.cisco.com/performance/mpi-and-java-redux/

HN discussion> If the US acquired a next-generation Chinese fighter, wouldn't it be handy if someone had the expertise to tell you exactly how its parts were made and machine replicas if needed? I suppose they could always call the engineers at Boeing or Lockheed who designed it in the first place. Like getting tech support for your Huawei networking equipment, just use the Cisco guide!

HN discussionLet me give it a shot with actual references, and years of paying attention, not whatever I heard the talking heads say last night. The US perceives the economic relationship with China to be one way. Prior to the recent trade flair ups, China was given preferential treatment, perhaps as part of a strategy to create a geopolitical ally instead of an enemy through trade. This appeared to be working for several decade…

HN discussionSure it is: https://blogs.cisco.com/collaboration/cisco-leap-frogs-h-264... Video encoding is a modeling and search problem. Codecs try lots of different ways to represent the input data and do their best. You can evaluate the costs and benefits of each piece of the encoder to decide which parts to have on or off. Obviously a speed-tuned AV1 compressor won't achieve maximum efficiency, but it might still perform bet…
