I saw this on Phys.org 2 days prior, but I think it's somewhat of a given that these science news sites are for all intents and purposes content farms - their primary utility is for surfacing interesting bits that you can do your own f

I have a bit of an armchair interest, although by no means am I an industry expert. The term I started off searching for was for "embodied energy" cost and "eroi" (energy return on investment). Here's one of the top

The Dell Precision looks like a good option if you don't need a better GPU (Quadro M2000M ~= GTX960m). I've been doing VR dev so I went w/ an Aorus (the smaller X3v6 on preorder), but you may want to look at something like th

Interesting, my original understanding was that they were using the blockchain for uniqueness for Corda, but it looks like it's optional: https://r3cev.com/blog/2016/4/4/introducing-r3-corda-a-distr.

I spoke at length w/ a friend working on mortgage-backed securities for GS a few years ago and dealing with third-party (and even intra-office) trust was specifically why he was looking into blockchains, but I'll admit to not bein

The Bitcoin whitepaper [1] (which is very short, concise, and definitely worth the read) describes how the Merkle trees might be pruned (transactions could be pruned when all outputs are spent) and in fact Bitcoin 0.11 added pruning (and 0.

I'm all for deflating blockchain hype, but I found the overall tone of the article pretty disagreeable, and more importantly, wholly missing the point. "In other words, the only thing previously stopping the standardization of rec

I'd say your primary reason for using a Mac is actually a smaller minority than you think. I think the primary appeal of Hackintoshes these days is that you can literally build systems for half the price that perform twice as well as w

Considering their 8+ years of negative GDP growth, there's not a lot to point out that they won't go bankrupt or will be able to service their debt when they have to start paying again (2022) anyway. From the most recent IMF proje

It's fair to argue about the European economy being a mess and all the crazy fiscal policy issues (personally, I think the only sane choice for Greece last year would have been to leave the EU), but I think the UK has misjudged what a

As a point of reference, 7% of UK GDP (2.678T USD in 2013 [1]) is roughly 187B USD. UK M3 might be a better measure, about 2.44T GBP [2]. By that calculation, a 7% haircut comes out to about 236B USD if I did my conversions correctly. [1]

If you're looking to do primarily CUDA/OpenCV work you'd be crazy to not build your own PC/drop in a new Pascal card. $450 will get you a GTX 1070 that should easily do 7 TFLOPs of SP (w a slight overclock), and for $600

Super neat stuff, looks like you guys have a solution that fills a big gap (the big disconnect is that you have hardware hackers who don't build up the stack or high level devs who have things they want to build but don't want to

I did the math a couple years ago, at 4K (next gen?) things get reasonably useful (similar arc resolution to early 90's VGA monitors), and a 8K, you'd get pretty close to the arc resolution of looking at a 1080p screen everywhere
