LHC Reaches Over One Trillion Electron Volts 305

Posted by ScuttleMonkey from the zzzzzzzzzzot dept.
The LHC has become the world's highest-energy particle accelerator, weighing in at over one trillion electron volts. "Until now the LHC had been operating at a relatively low energy of 450 billion electron volts. On Sunday, engineers increased the energy of this 'pilot beam,' reaching 1.18 trillion electron volts at 2344 GMT. The previous record of 0.98 trillion electron volts has been held by the Tevatron accelerator since 2001. The LHC is eventually expected to operate at some seven trillion electron volts."

Are Ad Servers Bogging Down the Web? 387

Posted by CmdrTaco from the yes-of-course-they-are dept.
blackbearnh writes "The work of making high-volume web sites perform well is an ongoing challenge, and one that continues to evolve as the nature of web content changes. According to Google Performance Guru Steve Souders, fat JavaScript libraries and rich content are creating new problems for web site tuning, but one of the biggest problems lies outside the control of web site administrators — ad servers. In an interview previewing the upcoming Velocity Online conference run by O'Reilly, Souders talks at length about the real causes of poor web performance today, and in particular, the effect that poorly performing ad servers are creating. 'We adopted a framework of inserting ads, of creating ads, that's pretty simple. And because it's pretty simple, it's not highly tuned. That's one reason why we shouldn't be too surprised that we see performance issues in third party ads. The other reason is that ad services are not focused on technology. Certainly companies like Yahoo and Google and Microsoft, we're technology companies. We focus on technology. So it's not surprising that our web developers are on the leading edge of adopting these performance best practices. And it's also not surprising that ad services might lag two, three or four years behind where these web technology companies are.'"
