Descripción:Google Tech Talks September 12, 2008 ABSTRACT While performance and power-efficiency are both important, correctness is perhaps even more important. In other words, if your software is misbehaving, it is little consolation that it is doing so quickly or power-efficiently. Google has already done a very impressive job of addressing one of the reasons why software may misbehave, which is that the underlying hardware may fail. In the Log-Based Architectures (LBA) project, however, we are focusing on perhaps an even more challenging source of misbehavior, which is that the application itself contains bugs, including obscure bugs that only cause problems during security attacks. Software bugs are difficult to recognize, and they are particularly problematic because they may cause every node in the system to fail (unlike hardware failures, which tend to be more isolated). To help detect and fix software bugs, we have been exploring techniques for accelerating dynamic program monitoring tools, which we call "lifeguards". Lifeguards are typically written today using dynamic binary instrumentation frameworks such as Valgrind or Pin . Due to the overheads of binary instrumentation, lifeguards that require instruction-grain information typically experience 30X-100X slowdowns, and hence it is only practical to use them during explicit debug cycles. Our goal is to reduce these overheads to the point where lifeguards can run continuously on deployed code. To accomplish this, we create a dynamic log of instruction-level events in the monitored application and stream this information to one or more lifeguards running on separate cores on the same chip multiprocessor (CMP). In our results so far, we have shown that the basic logging approach typically reduces the slowdown by roughly an order of magnitude from roughly 30X to roughly 3X. In a recent ISCA paper, we demonstrated several hardware-based techniques that can eliminate redundancy in the even-driven lifeguards and reduce the slowdown to just 20%. In our ongoing research, we are attempting to achieve similar performance through software-only techniques (by extending dynamic compiler optimization techniques to eliminate redundancy within the lifeguards), and we are extending our support to parallel and concurrent environments. We believe that our techniques are applicable to any event-driven lifeguards that processes streams of events, and are compatible with sampling-based techniques that can further reduce the power and performance impacts of monitoring. This talk will describe the work that we have done so far, as well as our plans for future research. Speaker: Todd Mowry Todd C.

With no breath and no pulse a frantic resuscitation effort begins as Bondi lifeguards come to his rescue. Finally a defibrillator shocks him back to life. Ten minutes after the incident Taka is fully conscious.

Descripción:New York, Long Island . Cedar beach. Mission Accomplished. July 20 2008 . If you want to help and make a difference around the world and in the U.S. support all the work that Save the Children does to help children in need visit: www.savethechildren.org Life guard on duty saved a young girl from drowning. To video the event I used a Sony Cyber shot, HD 1080, 8.1 camera. I was walking closer to the rescue site while recording the rescue. We're not talking Baywatch here. Being a good lifeguard is more difficult than most people imagine. After all, lifeguards do much more than just fish folks out of the water. Most are certified in emergency medical training and are trained to perform cliff rescues, helicopter rescues, and flood evacuations. In addition, they're certified search-and-rescue divers, as well as deputized law-enforcement officers. Lifeguards rely on their instincts to spot red flags. Rip currents are the most relentless beach hazard, so guards constantly scan for sandy-colored waves and currents, dead giveaways that a rip has formed. They study the swimming habits of beachgoers, as well as their clothing (T-shirts and cut-off shorts may indicate the person doesn't swim in the ocean very often). They also watch beachgoers' general behavior: Are they confident, timid, unsteady, or overly risky? Music by: U2 - Beautiful Day, Hawaii Five-0, Mission Impossible Themes, Blackfield.

To me nightmare with the devil I'll go strong, I'll go strong All my friends now try to save me What a joke, what a joke While I'm melting in the rain, deep in pain, she is so far Will we ever meet again as friends, after so long? While I'm melting in the rain, deep in pain, she is so far Will we ever meet again as friends, after so long? Blackfield. StarSailor2001

Descripción:A near drowning in Brevard County happened on the same day rescuers issued a plea for more beach lifeguards. Cocoa Beach is one beach that would get a year-round lifeguard under an expensive proposal that was debated on Thursday. The man who was rescued drifted hundreds of yards down the beach before bystanders pulled him out, but there were no lifeguards nearby. A helicopter flew to the scene to aid the injured man.

Descripción:Short selection of lifeguard clips. Like our lifeboat crews, lifeguards save lives in dramatic rescues, but much of their vital work is done by preventing accidents in the first place. RNLI lifeguards patrol more than 100 beaches in the UK in peak season and assisted almost 10,000 people last year.

Descripción:The Life Guards' history stretches back to 1521, so making them the world's oldest extant unit in active service. The Life Guards have had an eventful history and trace their origins back to the "16 good men and true" which the Swedish dalesmen, the Dalecarlians, contributed to Gustav Vasa's life guardsmen in January 1521. The present day cavalry have their origins in the mounted 'ryttarfanor' established in the provinces of Uppland and Södermanland in 1536. http://www.livgardet.mil.se
