The Making of the PlayStation 125
Edge Online has an in-depth look at the beginnings of the first PlayStation console. It starts at Sony's partnership with Nintendo, the purpose of which was to integrate a CD-ROM drive into the SNES. A falling out between the companies led Sony to stubbornly pursue a market dominated by Nintendo and Sega. The console's technology and Sony's unusual position in the industry quickly attracted the interest of many developers and publishers, eventually leading to sales that emphatically won that round of the console wars.
"'There was a huge resistance inside the company to actually being in the videogames business at all,' explains Harrison. 'The main reason why the Sony brand wasn't really used in the early marketing of PlayStation was not necessarily out of choice, but it was because Sony's old guard was scared that it was going to destroy this wonderful, venerable, 50-year old brand. They saw Nintendo and Sega as toys, so why on Earth would they join the toy business? That changed a bit after we delivered 90 per cent of the company's profit for a few years.'"
Space Sails Could Bring Used Rockets Back To Earth 76
GordonCopestake writes "An article from New Scientist proposes that all new spacecraft have sails attached to bring them back to earth — a measure that would reduce the amount of garbage in space. From the article: 'The risk to spacecraft from a collision with space debris could be reduced by equipping launchers with a gossamer-thin "sail." The idea is to deploy the sail after the rocket has released its payload to amplify the drag of the last vestiges of the atmosphere, and so force the rocket out of orbit.'"
Wired has a related story about the risks faced by the space shuttles as they share orbits with tons of drifting space debris. "... in the 54 missions from STS-50 through STS-114, space junk and meteoroids hit shuttle windows 1,634 times necessitating 92 window replacements. In addition, the shuttle's radiator was hit 317 times, actually causing holes in the radiator's facesheet 53 times."
A Closer Look At Chromium and Browser Security 109
GhostX9 writes "Tom's Hardware's continuing series on computing security has an interview with Adam Barth and Collin Jackson, members of Stanford University's Web Security Group and members of the team that developed Chromium, the open-source core behind Google Chrome. The interview goes into detail regarding the sandboxing approach unique to Chromium, comparisons between the browser and its competition, and web security in general."
Comment This work has not seen any reasonable peer review (Score 3, Insightful) 106
This paper has not seen any reasonable peer review. There are indices simply missing. The letter l (ell) is clearly not a good index. He uses n for number of transactions, users and networks. He even uses n for networks and users in the same formula, which must mean that number of users and networks are identical. In the summation of the users he leaves the denominators simply away. Usually scientiest don't name laws after themselves.
This doesn't mean that the basic idea might be wrong, but the work itself doesn't support the argument.
