The Lazy Programmer’s Guide to Secure Computing
12
Google Tech Talk March 11, 2010 ABSTRACT Presented by Marc Stiegler. This presentation starts with a simple block of code written by the Lazy Programmer, to observe how laziness made the code more compact and simpler. We then define the Principle of Least Authority(POLA), and explain why it is a best practice for secure programming. We show how laziness in that first example enabled enforcement of POLA. We then put the Lazy Programmer through a series of increasingly more difficult tasks as management attempts to make the Lazy Programmer work hard. To achieve maximum laziness, the Lazy Programmer is driven toward increasingly more modular, encapsulating OO designs that happen to implement POLA; ultimately compelled to build systems with defense in depth to avoid work. A secret truth is thus revealed: lazy OO programmers have been using secure techniques for decades, if only they had known. We then describe the tools that turn laziness into correctly enforced security for JavaScript, Java, and distributed computing. Marc Stiegler is a researcher at Hewlett-Packard Labs who has written “Introduction to Capability Based Security,” and designed CapDesk and Polaris, a windows overlay that isolates applications from one another to allow virus safe computing.

The world of computing is changing all the time, so it can sometimes be hard to keep up with all the new features and the latest technology. What’s often most difficult is taking the complicated jargon and deciphering it to understand what the real benefits are. So we thought we’d try to help with some further explanation.

Cloud Computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name cloud computing was inspired by the cloud symbol that’s often used to represent the Internet in flow charts and diagrams.

COMPUTEX 2011 – ANTEC Unveils The New P280 Performance Computing Enclosure
25
FULL REPORT: www.futurelooks.com www.futurelooks.com – For the last little while, ANTEC’s P180 series has sort of looked, the same. While the cases are still one of the best on the market, they are really showing their age. At COMPUTEX 2011, we had Antec’s man responsible for the development of this case, Mr. Han Liu, personally take us through this brand new update to their performance line of computers chassis in his signature style. Our personally impressions of this case is that it was a long time coming and should please many people interested in a tasteful and understated design that cools well and can be configured for quiet computing as well.
