How Browsers Work: Behind the Scenes of Modern Web Browsers
Web browsers are the most widely used software. In this primer, I will explain how they work behind the scenes. We will see what happens when you type google.com in the address bar until you see the Google page on the browser screen. The browsers we will talk about There are five major browsers used on desktop today: Chrome, Internet Explorer, Firefox, Safari and Opera. The browser's main functionality The main function of a browser is to present the web resource you choose, by requesting it from the server and displaying it in the browser window. The way the browser interprets and displays HTML files is specified in the HTML and CSS specifications. Browser user interfaces have a lot in common with each other.

Paul Grosss Blog - Useful unix tricks - part 2
Update (2/20/09): Check out Useful unix tricks – part 3 and Useful unix tricks – part 4 I covered a bunch of unix command line tricks in my previous blog post: Useful unix tricks. Here are some more. Learn vi Even if you prefer another text editor (such as emacs), it is worth your time to learn vi. vi is installed on every unix box, whereas emacs and others are not. Use less instead of tail I find that I often want to see the end of a file. % tail /var/log/messages Inevitably, I realize that I need more than the last 10 lines. % tail -n 100 /var/log/messages However, an easier approach is to use less to display the whole file and then jump to the bottom (using Shift+g): % less /var/log/messages Shfit+g Now, I can scroll up and down at will. mkdir -p creates nested directories By default, mkdir will only create a top level folder. % mkdir some/nested/folder mkdir: cannot create directory `some/nested/folder': No such file or directory % mkdir -p some/nested/folder The f flag output looks like:
The Shapes of CSS - StumbleUpon
Learn Development at Frontend Masters CSS is capable of making all sorts of shapes. Squares and rectangles are easy, as they are the natural shapes of the web. Add a width and height and you have the exact size rectangle you need. Add border-radius and you can round that shape, and enough of it you can turn those rectangles into circles and ovals. We also get the ::before and ::after pseudo elements in CSS, which give us the potential of two more shapes we can add to the original element.

How To Change The Windows 7 Logon Background
Windows 7 comes packed with a lot of new and interesting backgrounds. However Windows 7 fails to include an easy way to change the background you see every single time you login to your computer. Perhaps you want a little flavor, or maybe you just don’t like the built-in background. [learn_more caption="Editor Update 7/27/11"]After much feedback in the comments, if you’re not comfortable updating the system registry – I recommend you read this groovyPost which reviews the process of updating the Winodws 7 logon background using a freeware tool instead. A few things to note about your background image Windows will only recognize an image of the following resolutions:768×1280 960×1280 900×1440 1024×768 1024×1280 1280×768 1280×960 1280×1024 1360×768 1440×900 1600×1200 1920×1200Any image used as a background must be smaller than 245 KB in file size, regardless of resolution.The image used must be saved in .jpg format. Okay… that handles the fine print, lets get started. 2. 3. 4. All done!
creating an in-house dropbox
In this article we try to mimic the great Dropbox. This part of the series deals with setting up basic file synchronization in Linux. Create a Central Repository Create a folder on a large hard drive or raid your main computer/server For example: mkdir /meda/drobo/inhouseDropbox On the repository machine install Unison sudo apt-get install unison On the local machine connect via SSH and test that the install went ok ssh yourhostname unison -version You should see something like, “unison version 2.27.57“. Create a file in your repository directory: > test.txt Install Unison on the Local Machine For a Debian based system do: Make a folder in your home directory or wherever you want: mkdir /home/nixtutor/inhouseDropbox Then run Unison: unison inhouseDropbox/ Note the double slash after the hostname. You will be greeted with a message saying that this is the first time it has detected changes go ahead and hit the space bar. Setup Unison If should look something like:
C++ Programming/Exercises/Iterations - Wikibooks, open books for an open world - StumbleUpon
Iterations[edit] Solutions requirements Solutions must: Use only standard C++.Be compilable.Be in accordance to general coding practices. and should: Handle error situations, even if behavior is not defined. Please do not add solutions that are 99% similar to another that is already present, if it is an improvement just add it to the existing solution. EXERCISE 1[edit] Write a program that asks the user to type an integer and writes "YOU WIN" if the value is between 56 and 78 (both included). int main() {int i; cout << "Type all numbers between 58 and 73: " << endl; cin>>i; if (i>=58 && i<=78) { cout << "YOU WIN" << i << endl; else cout<<"YOU LOSE!" EXERCISE 2[edit] Write a program that asks the user to type all the integers between 8 and 23 (both included) using a for loop. Solution Alternative solution by Bartosz Radwanski //Alternative solution by Bartosz Radwanski//This one allows the numbers to be entered in random order and exits//when all correct numbers have been entered.

7 Ways to Lean to Code Right Now for Free
Learning to code is one of the most powerful and satisfying things you can ever do. If you’re a designer, learning to code can help you understand what you’re creating for, and if you’re looking to build a startup from scratch, being a technical founder can make things exponentially easier for you. No matter why you want learn, the only thing you really need is curiosity. But if you’re just starting out as a novice and don’t know where to begin, here’s a list of 7 ways to start learning how to code right now for free: 1. Processing is an open source programming language and environment for people who want to create images, animations, and interactions. ➤ Processing (Reference, Tutorials, Wiki, Forum, Inspiration) 2. Codecademy bills itself as “the easiest way to learn how to code,” and thanks to this startup, learning to code online has never been so accessible. ➤ Codecademy 3. Bloc, a new educational startup, makes it easy for you to start writing in Ruby. ➤ Bloc 4. ➤ Meetup, Hackathons 5.
