Hugo Villeneuve writes "What piece of code, in a non-assembler format, has been run the most often, ever, on this planet? By 'most often,' I mean the highest number of executions, regardless of CPU type. For the code in question, let's set a lower limit of 3 consecutive lines. For example, is it:
A UNIX kernel context switch?
A SHA2 algorithm for Bitcoin mining on an ASIC?
A scientific calculation running on a supercomputer?
A 'for-loop' inside on an obscure microcontroller that runs on all GE appliance since the '60s?"Read Replies (0)

jones_supa writes "OpenGL debugging has always lagged behind DirectX, mainly because of the excellent DX graphics debugging tools shipping with Visual Studio and GL being left with APITrace. Valve's Linux initiatives are making game companies to think about OpenGL, and the video game company wants to create a good open source OpenGL debugger to improve the ecosystem. AMD and Nvidia have already expressed interest in helping them out. Valve has been developing VOGL mostly on Ubuntu-based distributions under Qt Creator. The software currently supports tracing OpenGL 1.0 through 3.3 (core and compatibility), and is expected to eventually support OpenGL 4.x. Many more details on VOGL can be found at Valve's Rich Geldreich's blog."
This looks much
nicer than BuGLe
. Valve is using Mercurial for version control and they plan to throw it up on bitbucket under an unspecified open source license soon. It works with clang and gcc, but debugging with gcc is currently very slow (hopefully something that can be fixed once the source is available and the gcc hackers can see what's going on). The tracer's internal binary log format can be converted into JSON for use with other tools as well.Read Replies (0)
What Makes a Genius?

Hugh Pickens DOT Com writes "Eric Barker writes at TheWeek that while high intelligence has its place, a large-scale study of more than three hundred creative high achievers including Leonardo da Vinci, Galileo, Beethoven, and Rembrandt has found that curiosity, passion, hard work, and persistence bordering on obsession are the hallmarks of genius. 'Successful creative people tend to have two things in abundance, curiosity and drive. They are absolutely fascinated by their subject, and while others may be more brilliant, their sheer desire for accomplishment is the decisive factor,' writes Tom Butler-Bowdon. It's not about formal education. 'The most eminent creators were those who had received a moderate amount of education, equal to about the middle of college. Less education than that — or more — corresponded to reduced eminence for creativity,' says Geoffrey Colvin. Those interested in the 10,000-hour theory of deliberate practice won't be surprised that the vast majority of them are workaholics. 'Sooner or later,' writes V. S. Pritchett, 'the great men turn out to be all alike. They never stop working. They never lose a minute. It is very depressing.' Howard Gardner, who studied geniuses like Picasso, Freud, and Stravinsky, found a similar pattern of analyzing, testing, and feedback used by all of them: 'Creative individuals spend a considerable amount of time reflecting on what they are trying to accomplish, whether or not they are achieving success (and, if not, what they might do differently).' Finally, genius means sacrifice. 'My study reveals that, in one way or another, each of the creators became embedded in some kind of a bargain, deal, or Faustian arrangement, executed as a means of ensuring the preservation of his or her unusual gifts. In general, the creators were so caught up in the pursuit of their work mission that they sacrificed all, especially the possibility of a rounded personal existence,' says Gardner."Read Replies (0)

Hugh Pickens DOT Com writes "CNN reports that Ohio inmate Dennis McGuire appeared to gasp and convulse for roughly 10 minutes before he finally died during his execution by lethal injection using a new combination of drugs. The new drugs were used because European-based manufacturers banned U.S. prisons from using their drugs in executions — among them, Danish-based Lundbeck, which manufactures pentobarbital. The state used a combination of the drugs midazolam, a sedative, and the painkiller hydromorphone, the state corrections department told CNN. In an opinion piece written for CNN earlier this week, a law professor noted that McGuire's attorneys argued he would 'suffocate to death in agony and terror.' 'The state disagrees. But the truth is that no one knows exactly how McGuire will die, how long it will take or what he will experience in the process,' wrote Elisabeth A. Semel, clinic professor of law and director of the Death Penalty Clinic at U.C. Berkeley School of Law. According to a pool report from journalists who witnessed the execution, the whole process took more than 15 minutes, during which McGuire made 'several loud snorting or snoring sounds.' Allen Bohnert, a public defender who lead McGuire's appeal to stop his execution in federal court on the grounds that the drugs would cause undue agony and terror, called the execution process a 'failed experiment' and said his office will look into what happened. 'The people of the state of Ohio should be appalled by what took place here today in their name.'"Read Replies (0)
