Literally. That's what the article says if you click through the summary and rewrite to actually read it. To quote: "What the Google founders recognized about search on the Web was that information about LINKS could be added to the algorithms." Which isn't wrong, of course, but if you call yourself a nerd you already know a hell of a lot more about the page ranking algorithm than this already.

Comment Real-world case (Score 1) 258

In the parliamentary elections of September 2013, more than 250 000 Norwegians in selected municipalities were able to vote from home. They were taking part in a national trial of Internet voting, building on an advanced cryptographic protocol. Follow the link below for a talk about the technology behind it, presented at the last Chaos Computer Conference by Tor E. BjÃrstad http://media.ccc.de/browse/con...

The age of the square, visible pixel was actually a pretty short period between blurry CRTs and retina LCDs. Pixel art was originally created for CRT, which blurs the pixels. Artists developed techniques to take advantage of this.

Comment Re:why dont they spin it? and land it in a silo? (Score 1) 342

The spinning would have to be slow enough that you could either gimbal the nozzle or modulate the thrust at the same frequency as the spinning. I don't know which of the two controls is faster. I don't know about the economics of this. It's probably not economical.

A bit of rotation should help to keep the thing upright. The gases being pushed into the silo will be forced towards the walls on their way back out and help center the rocket as it enters the silo. A funnel-shaped silo is easy to hit and provides a soft cushion as the pressure of the backscattered gas increases as the rocket descends into it. Finally, a rotating platform at the bottom needs to be synchronized to the rocket's own rotation. Good Thing I don't have the billions it would take to see my brilliant ideas crash and burn.

Comment Re:Are there open source tools... (Score 1) 64

I have no such illusions. But I would expect open source tools to at least function equally across FPGA brands, at least to the extent that people are able to reverse engineer the bitstream formats of the various architectures. The quality of software in general correlates strongly with the amount of manpower that is put into it, which again correlates strongly with funding. On that note, I think the case could be made that some FPGA producers would benefit from an open source and cross-platform toolstack, particularly those that are not currently market leaders.

There are several open source vhdl / verilog projects, including tools for simulation and synthesis, mapping, placing and routing. Examples: HANA, yosys, Icarus. But I guess you usually get better results with the free-as-in-beer tools from the fpga manufacturers. Which is a shame, since it would be nice to have some open source tools. Although everyone use the same hardware definition languages, it is a pain in the neck to switch between FPGA brands, mostly because the build tools are different and all pretty quirky.

The generation of random numbers is too important to be left to chance.
