Source: Security DevCenter The typical trial-and-error approach to diagnosing and solving performance problems breaks down when the problems are difficult. As the complexity of the problem increases, so does the need for a methodical approach and powerful tools. This tutorial will teach you how to be systematic. We'll run through the process and then emphasize getting to know your toolkit, including iostat, vmstat & mk-query-digest. You will learn the approach Percona consultants have put to use across thousands of customer machines. We're going to try and teach you to be as practical as possible, with only minimal emphasis on performance theory where it's needed. The main focus will be on MySQL versions 5.0, 5.1 and XtraDB on Linux operating systems.

Source: Security DevCenter There was a time when film grain was a problem for some photographers. That concern translated into a concern with digital noise. Many words have been written on the techniques in many applications to remove or lessen digital noise or grain in modern images. Some even seek to find ways to remove the grain from old film photographs. Despite all of this, grain has its place in modern digital photography. Grain now brings with it the charm and nostalgia of bygone film days. When compositing images, grain can be the unifying effect bringing different images from different times together for a great composite. Adding grain to a black and white or sepia image can add a pleasing artistic texture to the work. Whatever the reason, many photographers add grain to an image. Sometimes after working diligently to remove digital noise! But, then, grain isn't noise.

As with any version of Lightroom it all begins with Import. And this time around we have an entirely new and improved import feature. While this has been the source of some consternation and controversy, once you dig in and look at what's new here I think you'll be on board.

Source: Security DevCenter Duration: Approximately 60 minutes. Cost: Free Time is money, the saying goes. And nowhere is this more true than in the world of finance. GPU supercomputing, with its ability to speed up many types of financial calculations by orders of magnitude (x10, x100, ) looks set to do very well in finance. Indeed, it has already made significant inroads into financial analytics and risk in what looks like a silent revolution on Wall Street. The revolution has gone unnoticed for a while, but more and more financial players are seeing--and reaping--the benefits of GPU supercomputing. GPU supercomputing in finance is about doing things faster than ever before. Trading is already mostly real-time, because it pays to be there first, ahead of the other guy. And even those aspects of finance that are not yet real-time (currently risk and compliance often lag behind trading), they are moving to real-time as well. In fact, the whole world seems to be moving to real-time; finance will simply get there first because the incentives are so great. Based on a review of numerous downtime events over the past few years, this talk will present a simple framework that you can use inside your company to handle downtime effectively, and give you advice on how to get it adopted within the organization. But with all this newfound speed there are dangers. Is faster really better for financial markets as a whole? Does faster mean more abundant liquidity, or less? More volatility, or less? Do the regulators need to go real-time in what amounts to a regulatory compliance arms race? And should they equip themselves with the same tools? GPU supercomputing looks to be sufficiently powerful and cheap--and orders of magnitude speedups must inevitably change the rules of the game--so this presentation will touch upon some wider policy-related issues. This talk will give an overview of GPU supercomputing in finance: how it is being applied now, and where it's going; what sorts of problems in finance that GPUs are a good match for, and what problems are not, and how it might profitably be applied in your business.
