There are a lot of knobs you can use to get better performances from SSL: choosing the best implementation, using more CPU cores, switching to 64bit system, choosing the right cipher suite and the appropriate key size and enabling a session cache.
We will consider three SSL terminators. They all use OpenSSL behind the hood. stunnel is the oldest one and uses a threaded model. stud is a recent attempt to write a simple SSL terminator which is efficient and scalable. It uses the one-process-per-core model. nginx is a web server and it can be used as reverse proxy and therefore act as SSL terminator. It is known to be one of the most efficient web server, hence the choice here. It also features built-in basic load balancing. Since stud and stunnel does not have this feature, we use them with HAProxy, an high performance load-balancer that usually defers the SSL part to stunnel (but stud can act as a drop-in replacement here).
Für den einen sind es traurige Reste vergangener Hardware-Herrlichkeit, ein anderer sieht darin wertvolles Baumaterial: ausgediente Diskettenlaufwerke, unwirtschaftliche Drucker, ausgemusterte Server, Plotter, Terminals, Scanner und so weiter. Mit Erfindungsgeist, Mut, ein paar Werkzeugen und einem guten Schuss Humor machen findige Leute daraus sinnreiche neue Vorrichtungen, mit denen sie Alltagsprobleme lösen, oder originelle Kunstwerke, die zum Staunen reizen.

Author of the cyberpunk novel Neuromancer, William Gibson talks about the relationship between his fiction and the contemporary urban landscape
In the server environments, disk storage is becoming more and more important, and the choice of hard drives is very broad - connectivity intefaces (SAS, SATA) and their speeds, rotational speeds, desktop vs nearline vs enterprise drives, form-factors and so on. How to choose the most appropriate HDD drive type?
The purpose of this document is to discuss currently available internal and external HDD storage interfaces for IBM® System x® servers and to provide recommendations on how to choose the right options to better fit business needs and application requirements. The document is organized into the following sections:
After giving away their margins, publishers have let marketing and royalties for most of their writers slide
Die Welt wird sich in den nächsten Jahren gewaltig ändern. Die Vorstellung, ausgerechnet die Formen des wirtschaftlichen, politischen, kulturellen Zusammenlebens, die sich auch in Europa erst nach dem Zweiten Weltkrieg durchgesetzt haben, würden das 21. Jahrhundert prägen, hat angesichts der demografischen und der Machtverhältnisse etwas Tollkühnes. Es wird neue Balancen von Volksbeteiligung, von Wirtschaftsmacht und Herrschaft geben. Die neuen Medien werden darin wichtige Rollen spielen.
There's nothing simple about enterprise security, but there are plenty of best practices that can keep most businesses safe from the most likely and pervasive threats. Unfortunately, according to a new study from research firm Echelon One and enterprise key and certificate management company Venafi, more than half of all IT departments are failing at some of the most important security practices. Here are the top 5 things your company could probably do better.
Microsoft's 1.7 million quarterly phone sales compare to 46.8 million for Android, 23.9 million for Nokia's Symbian, 19.6 million for the iPhone and 12.7 million for BlackBerry. [...]
The only major platform Microsoft is outselling is apparently HP's WebOS, which doesn't even show up in the rankings because it sold so poorly.
new research from GigaOM Pro and Isurus Market Research & Consulting, sponsored by IT support vendor Bomgar, suggests the Millennials have more respect for the IT organization than most of us give them credit for.
earch the news for "copper theft" and look through the headlines. LOOK. Why are there so many stories? Stealing wire to sell the copper? From a cell tower? What is this, the Great Depression?
Reports from the Department of Energy estimate that copper theft is responsible for $1 billion worth of damage every single year. The problem is so rampant that there's a coalition to prevent copper theft. State laws are being passed left and right, requiring close monitoring of all copper sales. What gives? It's the economy, stupid.
The primary conflict of interest at Moody's is well known: The company is paid by the same "issuers" (banks and companies) whose securities it is supposed to objectively rate. This conflict pervades every aspect of Moody's operations, Harrington says. It incentivizes everyone at the company, including analysts, to give Moody's clients the ratings they want, lest the clients fire Moody's and take their business to other ratings agencies.
Moody's analysts whose conclusions prevent Moody's clients from getting what they want, Harrington says, are viewed as "impeding deals" and, thus, harming Moody's business. These analysts are often transferred, disciplined, "harassed," or fired.
In short, Harrington describes a culture of conflict that is so pervasive that it often renders Moody's ratings useless at best and harmful at worst.
The author of Free Ride warns that digital piracy and greedy technology firms are crushing the life out of the culture business
In this work, we carefully design and implement RSA, AES, and HMAC-SHA1 algorithms in GPU, and show that GPUs can perform cryptographic operations much faster than CPUs and incur small latency enough to be used in the interactive network applications.
The big feature of this release — and the reason for the new version number — are the new WebDriver APIs for Python, Ruby, Java and C#. These have been in development for over four years, and are already widely used, trusted and depended on. The WebDriver APIs have been written by developers familiar with each language, so they feel like they belong there. We’re very proud of them, and hope you enjoy using them.
Support for WebDriver is also baked into Opera and Chrome, and we’re working closely with Mozilla to ensure that their browsers also support it. Looking to the future, WebDriver also works on both Android and iPhone, allowing you to test your sites on the next wave of the Web.
The three big Web companies launched the initiative, known as Schema.org, last week. It defines an interconnected vocabulary of terms that can be added to the HTML markup of a Web page to communicate the meaning of concepts on the page.
Which of today’s technology giants might still be standing tall a century after their founding? What is unusual about IBM, which celebrates its 100th birthday next week, is that it has been so successful for so long in the fast-moving field of technology.
