Oracle acquired Sun Microsystems in 2010, and since that time Oracle's hardware and software engineers have worked side-by-side to build fully integrated systems and optimized solutions designed to achieve performance levels that are unmatched in the industry.

Sun Microsystems

Early examples include the Oracle Exadata Database Machine X2-8, and the first Oracle Exalogic Elastic Cloud, both introduced in late 2010. During 2011, Oracle introduced the SPARC SuperCluster T4-4, a general-purpose, engineered system with Oracle Solaris that delivered record-breaking performance on a series of enterprise benchmarks. Oracle's SPARC-based systems are some of the most scalable, reliable, and secure products available today. Sun's prized software portfolio has continued to develop as well, with new releases of Oracle Solaris, MySQL, and the recent introduction of Java 7.

Oracle invests in innovation by designing hardware and software systems that are engineered to work together. Services & Support. Visio Cafe. C - Your Resource for C and C++ Programming. Math For Programmers. I've been working for the past 15 months on repairing my rusty math skills, ever since I read a biography of Johnny von Neumann. I've read a huge stack of math books, and I have an even bigger stack of unread math books. And it's starting to come together.

Let me tell you about it. Conventional Wisdom Doesn't Add Up First: programmers don't think they need to know math. And you know what? But hey, you don't really need to know how to program, either. If you're suddenly feeling out of your depth, and everyone appears to be running circles around you, what are your options? In fact, I don't think you need to know anything, as long as you can stay alive somehow. So they're right: you don't need to know math, and you can get by for your entire life just fine without it. But a few things I've learned recently might surprise you: Math is a lot easier to pick up after you know how to program.

The Math You Learned (And Forgot) Here's the math I learned in school, as far as I can remember: Curses Programming with Python — Python v2.7.2 documentation. Abstract This document describes how to write text-mode programs with Python 2.x, using the curses extension module to control the display.

Curses Programming with Python — Python v2.7.2 documentation

What is curses? The curses library supplies a terminal-independent screen-painting and keyboard-handling facility for text-based terminals; such terminals include VT100s, the Linux console, and the simulated terminal provided by X11 programs such as xterm and rxvt. Display terminals support various control codes to perform common operations such as moving the cursor, scrolling the screen, and erasing areas. Different terminals use widely differing codes, and often have their own minor quirks. In a world of X displays, one might ask “why bother”? The curses library hides all the details of different terminals, and provides the programmer with an abstraction of a display, containing multiple non-overlapping windows. No one has made a Windows port of the curses module. The Python curses module Starting and ending a curses application Windows and Pads. The Craft of Text Editing. -by- Craig A.

Domain Name System (DNS) converts the name of a Web site ( to an IP address (

Quick HOWTO: Configuring DNS

This step is important, because the IP address of a Web site's server, not the Web site's name, is used in routing traffic over the Internet. This chapter will explain how to configure your own DNS server to help guide Web surfers to your site. Before you dig too deep in DNS, you need to understand a few foundation concepts on which the rest of the chapter will be built.

DNS Domains Everyone in the world has a first name and a last, or family, name. BIND is an acronym for the Berkeley Internet Name Domain project, which is a group that maintains the DNS-related software suite that runs under Linux. DNS Clients A DNS client doesn't store DNS information; it must always refer to a DNS server to get it. Authoritative DNS Servers Authoritative servers provide the definitive information for your DNS domain, such as the names of servers and Web sites in it. The Host Command. TigerDirect.
