Good point. Yes, if the range of random numbers chosen is small. If the random numbers being exchanged are N bits long and the length of the hash is also N (say N = 256), then a salt should be unnecessary, right? Inverting an essentially ra

This approach alone is not enough. A cheating bot could wait until they received the input+number from all other players, then choose their own number as needed to obtain the desired "random" result. A workaround is to have all pa

The flip side of this is that publishing information is a better way to transmit information than placing orders on an exchange by many orders of magnitude. If insider trading is legalized, the incentives are stacked even further toward

Once solar becomes widespread enough, the dynamic changes. In Germany, electricity spot prices can be lower around noon because of solar energy. A quick Google search brings up this example: http://cleantechnica.com/2012&#

I'm not sure if you're seriously looking for an answer. If you are, it's actually rather obvious: As long as there is a piece of unclaimed land, it is sufficient for a single person/organization/state to decide at s

I'm not dietrichepp, but that's the gist of it. Look into how multiplexers are actually implemented, and it becomes painfully obvious that hardware cannot magically solve your problems. And the "even if we don't get regi

Your comment only contains a very individualistic perspective. Sure, it's a great experience to share some of what you have accumulated over your life, for you personally and for your children. That doesn't mean that it's a p

I'm torn about whether to agree with you. On the one hand, I absolutely see your point. On the other hand, having played around with two iterations of Oculus' VR headset, I absolutely understand where this direction is coming from

Right, that's absolutely a problem, but it's orthogonal to the supposed problem that OP was mentioning (e.g., it could be that those funds are so bad that even the top quartile doesn't outperform the index in a particular

Actually, I would argue that for the purpose of what the article was trying to convey, they used the right statistic. Let me illustrate by running with your own suggestion of trying to find out whether there are actively managed funds that

You make a very good point. I do like to give you one additional aspect to consider: While the Mill saves on instruction scheduling logic (and register renaming, and certainly also has the benefit of re-thinking opcodes and instruction deco

You are certainly right in a sense, because both FPGA and silicon is usually described using some VHDL or Verilog. So once they have a working FPGA, it's not too difficult to get it into some silicon. However, to get it into fast a

It's a good thing that we shy away from excessive punishments. The point here is simply that what is excessive may depend on the person being punished. In that sense, your premise is not a counter-argument against what tellarin wrote.

What exactly are you referring to? log 100M is roughly 27. A call stack depth of 27 has not been an issue on any general purpose system for a very long time now. Granted, there are certainly some niches left where you'd want to avoid

There is a whole field of algorithms that are best described recursively where the recursion depth is guaranteed to be logarithmic. Sorting algorithms like merge sort are a basic example. Using recursion for those is fine . Apart from that

When Intel say they have 52nm wire pitch, this means that they produce wires that are 26nm wide, with 26nm distance between wires. Producing wires that are thinner, or that are closer together, is unreliable. That said, they are probably ab

This is a common misconception about economic growth. Economic growth often means more physical stuff, but there is by no means a fixed link between the two. Higher quality products built out of the same amount of physical stuff have a high

Since there is an obvious political slant to the message, it should be pointed out that it is the finance industry itself that is "printing money". So take that into account while thinking through the political implications, if sk

There is no such direct causality. The value of a currency (in the sense of exchange rates and prices of goods) is determined by supply and demand, and nothing else . People with the mindset of "USD government printing money => val

I would agree with you if this were only about adware. The problem is that the adware opens a massive security hole that is exploitable by everybody . The Lenovo adware wants to hijack SSL connections. To do so, it installs its own CA, and

Sorry, but such a strong claim requires more justification. From what I know, it is orders of magnitude harder to hijack a package download over HTTPS than over HTTP. It is technically feasible for me to sit in a random coffee shop and do a

Those batteries can come in useful even when you're still connected to the grid. Right now, some locations have laws and/or regulation that force grid companies to buy solar-generated electricity from home owners at fixed rates. T

It's not that simple, because of inlining and macros. Those optimizations can be used to quickly throw out unnecessary code like null-pointer checks inside inlined functions, so they are valuable and good to have. So it's a matt
