Dual Boot Ubuntu and Windows

Although this may seem obvious, it is important to back up your files to an external backup medium before attempting a dual-boot installation (or any other hard drive manipulation), in case your hard drive becomes corrupted during the process. External hard drives, USB flash drives, and multiple DVDs or CDs are all useful for this purpose. Some computer manufacturers that pre-install Windows provide a Windows recovery/re-installation CD or DVD with the computer. However, many companies no longer ship a physical disc but instead create a hidden partition on the hard drive in which the recovery-disk information is stored.

4 Reasons Every Windows User Should Have An Ubuntu Live CD. For this reason, I suggest every Windows user keeps a copy of Ubuntu on hand, even if they never intend to switch from Windows.

4 Reasons Every Windows User Should Have An Ubuntu Live CD

Happily, Ubuntu is completely free to aquire. You can download Ubuntu and burn it yourself, but if that sounds like too much work you can request Ubuntu send you a Ubuntu Live CD for free. That’s right: you’ll get a CD in the mail, completely free of charge. There’s seriously no reason to not look into this, so let’s see some of the uses Ubuntu has for those who never intend to install it.

Use Ubuntu Live CD to Backup Files from Your Dead Windows Computer. If you’ve ever asked for help with your Windows computer that won’t boot anymore, you’ve probably been told to “Backup all your data and then reinstall”… but if you can’t boot, how can you get to your data?

Use Ubuntu Live CD to Backup Files from Your Dead Windows Computer

That’s the question we’ll be answering today. Python Introduction - Google's Python Class - Google Code. Python is a dynamic, interpreted language.

Python Introduction - Google's Python Class - Google Code

Source code does not declare the types of variables or parameters or methods. This makes the code short and flexible, and you lose the compile-time type checking in the source code. Python tracks the types of all values at runtime and flags code that does not make sense as it runs. (todo: link here to the companion video segment for this section) An excellent way to see how Python code works is to run the Python interpreter and type code right into it. Python Program Python source files use the ".py" extension. Linux is NOT Windows. In the following article, I refer to the GNU/Linux OS and various Free & Open-Source Software (FOSS) projects under the catch-all name of "Linux".

Linux is NOT Windows

It scans better. If you've been pointed at this page, then the chances are you're a relatively new Linux user who's having some problems making the switch from Windows to Linux. This causes many problems for many people, hence this article was written. Many individual issues arise from this single problem, so the page is broken down into multiple problem areas. Problem #1: Linux isn't exactly the same as Windows. 3. An Informal Introduction to Python — Python v2.7.1 documentation.

In the following examples, input and output are distinguished by the presence or absence of prompts (>>> and ...): to repeat the example, you must type everything after the prompt, when the prompt appears; lines that do not begin with a prompt are output from the interpreter.

3. An Informal Introduction to Python — Python v2.7.1 documentation

Note that a secondary prompt on a line by itself in an example means you must type a blank line; this is used to end a multi-line command. Many of the examples in this manual, even those entered at the interactive prompt, include comments. Comments in Python start with the hash character, #, and extend to the end of the physical line. Tips for Linux Explorers. Learning the shell.

Why do you need to learn the command line anyway?

Learning the shell.

Well, let me tell you a story. Not long ago we had a problem where I used to work. There was a shared drive on one of our file servers that kept getting full. Why Python? My first look at Python was an accident, and I didn't much like what I saw at the time.

Why Python?

It was early 1997, and Mark Lutz's book Programming Python from O'Reilly & Associates had recently come out. O'Reilly books occasionally land on my doorstep, selected from among the new releases by some mysterious benefactor inside the organization using a random process I've given up trying to understand. One of them was Programming Python. I found this somewhat interesting, as I collect computer languages. I know over two dozen general-purpose languages, write compilers and interpreters for fun, and have designed any number of special-purpose languages and markup formalisms myself.

Linux Shell Scripting Tutorial - A Beginner's handbook. The Art of Unix Programming. You can browse my newest book here. If you like it, please order a paper copy. You can get it from Amazon or Barnes & Noble, or direct from Addison-Wesley. The Art of Unix Programming attempts to capture the engineering wisdom and philosophy of the Unix community as it's applied today — not merely as it has been written down in the past, but as a living "special transmission, outside the scriptures" passed from guru to guru.

Accordingly, the book doesn't focus so much on "what" as on "why", showing the connection between Unix philosophy and practice through case studies in widely available open-source software. If you're using Opera 5, be aware that it has problems rendering some of the HTML in the browseable version linked above. Revisions for the first print edition are now closed. Instructions for reviewers are here. How To Become A Hacker. Copyright © 2001 Eric S. Raymond As editor of the Jargon File and author of a few other well-known documents of similar nature, I often get email requests from enthusiastic network newbies asking (in effect) "how can I learn to be a wizardly hacker? ". Back in 1996 I noticed that there didn't seem to be any other FAQs or web documents that addressed this vital question, so I started this one.

A lot of hackers now consider it definitive, and I suppose that means it is.
