HowStuffWorks "The Basics of C Programming" The previous discussion becomes a little clearer if you understand how memory addresses work in a computer's hardware. If you have not read it already, now would be a good time to read How Bits and Bytes Work to fully understand bits, bytes and words. All computers have memory, also known as RAM (random access memory). float f; This statement says, "Declare a location named f that can hold one floating point value." While you think of the variable f, the computer thinks of a specific address in memory (for example, 248,440). f = 3.14; The compiler might translate that into, "Load the value 3.14 into memory location 248,440." There are, by the way, several interesting side effects to the way your computer treats memory. int i, s[4], t[4], u=0; for (i=0; i<=4; i++) { s[i] = i; t[i] =i; } printf("s:t\n"); for (i=0; i<=4; i++) printf("%d:%d\n", s[i], t[i]); printf("u = %d\n", u); The output that you see from the program will probably look like this: s:t 1:5 2:2 3:3 4:4 5:5 u = 5 s[1000000] = 5;
How to Really Build Backlinks and Dominate Google Without a doubt, the most frequent post request I’ve had on this site is a post about link building. I rarely take requests, simply because people rarely know what they really want until you give it to them, but this time things are a little different. First of all, I have been studying SEO day and night since I was 16 (almost 5 years ago) and I’ve ranked on the first page of Google for some of the most competitive keyphrases in the world. Therefore, I like to think I know quite a bit about the topic and can provide some insights in this space. For those of you who don’t know why links are important, let me just say that if you want to get traffic from the major search engines, they’re crucial. A large percentage of my income to affiliate sites is from traffic via Google, and the difference between ranking 2nd and ranking 1st can literally be thousands of dollars extra on my bottom line. SEO is generally divided into two parts: on-site optimisation and off-site optimisation. Be Useful
Public Proxy Servers - Free Proxy Server List Hacking with Google Search Google is considered to be a powerful search engine that helps millions of users to find fast & easy useful webpages. Nevertheless Google Search can also be a handy tool in the hands of malicious users, spammers & hackers. In this article we will describe few tricks that can be used in Google Search in order to easily find and access pages that normally should be protected. At the end of the article we will discuss how webmasters can protect their sites from such attacks. Important Notice: The purpose of this article is to inform webmasters about the risks they face and help them secure their websites.

Rosenhan experiment Rosenhan's study was done in two parts. The first part involved the use of healthy associates or "pseudopatients" (three women and five men, including Rosenhan himself) who briefly feigned auditory hallucinations in an attempt to gain admission to 12 different psychiatric hospitals in five different states in various locations in the United States. All were admitted and diagnosed with psychiatric disorders. After admission, the pseudopatients acted normally and told staff that they felt fine and had no longer experienced any additional hallucinations. The study concluded "it is clear that we cannot distinguish the sane from the insane in psychiatric hospitals" and also illustrated the dangers of dehumanization and labeling in psychiatric institutions. The pseudopatient experiment[edit] Rosenhan himself and seven mentally healthy associates, called "pseudopatients", attempted to gain admission to psychiatric hospitals by calling for an appointment and feigning auditory hallucinations.
Demo | jQuery.popeye 2.1 | an inline lightbox alternative with slideshow x Note: To see the full potential of CSS3 styling (shadows, gradients, rounded corners, alpha transparency), please view this page in a modern webkit or mozilla browser (Firefox 3.5+, Safari 4, Opera 10.50, Chrome 4). Other browsers will degrade gracefully. Except for IE6, though, which I didn't bother to include. Feel free to come up with your own solution ;-) Example 1 The first popeye-box uses the standard options: it floats to the left and opens to the right, its navigation and caption show on mouseover. By placing the navigation inside the stage area (where the image is displayed), we can get it to hover above the image. No need to read this, just dummy text ;-) Vivamus ut nisi id libero interdum pretium. View HTML code used in this example Example 2 The navigation stays fixed to the right of the image.

37 Tested PHP, Perl, and JavaScript Regular Expressions inShare22 A regular expression, also called regex or regexp for short, is simply a piece of code that matches a pattern. Mastering regular expressions can be a difficult chore, and if you don't need them all of the time, the syntax is tricky enough to make the task frustrating or slow as you will constantly need to use a reference sheet. In order to save you time, I've compiled a list of PHP, Perl, and JavaScript regular expressions for common use cases that have been tested and are ready to go. This isn't a regular expression tutorial or even a reference; you can think of it more as a cheatsheet for when you just need the regex but don't want to put a lot of time into relearning regular expressions. If you're looking for regex tutorials or regex resources, you can find them at the end of the page as well as some additional regex resources.

"Perl for Newbies" - Part 1 - The Perl Beginners' Site Strings and data structures that are unlimited in size, nested to any depth. Powerful syntax and built-in functions. Extended, built-in support for regular expressions. Support for namespaces, classes, and objects. Perl was introduced in 1987 (4 years before Linux itself), when the author, Larry Wall, released version 1.000 of it. Since then, perl has seen several versions, each adding additional functionality. perl version 5, which was released in 1994, was a complete re-write of the perl interpreter, and introduced such things as hard references, modules, objects and lexical scoping. Perl became especially popular as a language for writing server-side scripts for web-servers. Links: Perl is interpreted, so no compilation is needed. After you are done, you should invoke the perl interpreter with the name of the file you created. At the command line (and press Enter). The fact that the program was executed does not mean it does what you want it to do. The neophyte "Hello World!" and
Geeks and Delegation: A Match Made in Hell Last week, I was invited to join 3,000 delegates to what turned out to be the largest entrepreneurship conference in the world. The Global Entrepreneurship Congress 2012 took place in Liverpool, UK (a few words about Liverpool in a moment) and its speakers and panels were selected in order to inspire us into entrepreneurial action. Upon arriving in Liverpool on the GEC Express Virgin train, chartered for the specific occasion (welcoming speech and random encounter with Sir Richard Branson), I didn’t know what to expect. One of the first things that I found out, to my surprise, was how geeky Liverpool is! It has more scientists than Cambridge and a booming game industry (it’s supposedly second in the UK). Sir Richard Branson was the main ”attraction” for the day and who could blame the the crowd? Q&A with Sir Richard Branson Delegation was the first skill I was forced to learn when I made the jump from a technical to a managerial position. Don’t drop the “ball”!
