Atlanta Linux Fest 2009

Jessica — Wed, 23 Sep 2009 14:27:00 -0400

I attended the Atlanta Linux Fest last Saturday. I only got to stay for two talks, but what I saw was great!

From the Ubuntu Kernel talk given by Pete Graner of Canonical, I learned a couple of interesting things about Ubuntu…

Canonical has teams that work on things other than the ubuntu kernel, including integration for OEMs like Dell and HP, maintaining LaunchPad, and distributing install cds. They are able to maintain a 6 month release cycle for Ubuntu by deciding to only fix those bugs that are truly critical and focusing on the goals decided at the Ubuntu Developer Summit.

Ubuntu One allows you to back up any number of systems into the cloud.

The folks at Canonical have created a version of android that runs on Ubuntu Notebook Remix. It sounded like android uses some of its own version of libraries so a unique version of android had to be compiled to use those libs.

I also saw Kirrily Robert give her Standing Out in the Crowd talk. If you missed OSCon 2009 or the Atlanta Linux Fest, you can check out her talk here.

Review of Ubuntu Hacks

Jessica — Mon, 09 Apr 2007 00:24:00 -0400

Why read Ubuntu Hacks?

If Ubuntu is the entry-level Linux distro, then Ubuntu Hacks is the book that helps the entry-level user take advantage of the great software and tools Linux has to offer.
I would have saved myself a lot of effort if I owned this book on the day that I install Ubuntu on my machine.
In many ways, Ubuntu Hacks is an introduction to the software available to all Linux users. So, if you are looking for some “real Ubuntu hacks”, you may be disappointed, _{but that is ok; that just means that the title of the book is a bit of a misnomer, but it doesn’t necessarily mean that the books isn’t valuable.}
Some subjects (like kernel building) aren’t really examined with much detail and refer users to seek help elsewhere.
The command-line based instructions are great for those new to using the terminal. There are quite a few hacks that provide visual instructions only, but Ubuntu Hacks had far less GUI-based instructions than the other Ubuntu books I perused at the bookstore.
If you aren’t a techie, but you want to explore Linux and its myriad of software options, Ubuntu Hacks is for you.
A lot of the hacks in Ubuntu Hacks you can figure out on your own or find on the internet.
Things that I would like to know about Linux/Ubuntu that weren’t addressed in Ubuntu Hacks:
- File system organization… whys and best practices (i.e. Hack #101 – Get a good visual picture of the linux file system in your head)
- A brief history of Linux, Debian and Ubuntu (i.e. Hack #102 – How to tell friends & family about Ubuntu in a non-freakish way)

One liners for linux, ruby and perl

NTFS and FAT compatible... finally

Jessica — Thu, 01 Feb 2007 20:03:00 -0500

My problem

Had an external hard drive that I used with my MS Windows machine.
Got a new linux machine.
External hard drive did not allow linux machine to write to it – because hard drive is NTFS.

How could I write to external hard drive from linux machine without re-formatting the external hard drive?

My solution

Follow this tutorial on How To Use NTFS Drives/Partitions Under Ubuntu Edgy Eft

The only instruction I would add to this tutorial is that you must have properly ejected the external hard drive from your Windows machine in order for Edgy to mount the drive.

UPDATE: I just found these instructions for mounting your Windows partition and making it read/writable.

mac ipod vs. windows ipod on linux

Jessica — Fri, 26 Jan 2007 11:43:00 -0500

I have discovered that mac ipods (those that have been restored to factory settings on a mac) are read by Ubuntu as read-only, which means you can’t change the music on a mac ipod from a Ubuntu machine [1]. Alternatively, windows ipods (those restored on a windows machine) are read/writable, which means you can upload new music to that ipod.

I figured this out after reading the ipod linux (a version of linux that runs on your ipod) installlation instructions. ipod linux requires that the ipod you want to install ipod linux on is a windows ipod. Since we don’t have a working windows machine at my house, I used a windows machine my husband brought home from work and restored the ipod to its factory settings on it. Thinking that the reason that ipod linux requires that windows ipods be used, I plugged my ipod up to my linux machine and tada, it wasn’t read-only!

1: I didn’t think about this until later, but I am guessing that I could have changed the device’s permissions using sudo. I thought I had tried that, but I guess I didn’t do it correctly.

One-liners

Jessica — Sat, 06 Jan 2007 22:18:00 -0500

and Frequently used commands I can’t seem to remember the exact syntax of. Nothin’ fancy.

Linux
find . -name \*.* | xargs grep search_string

navigate to folder you would like to search, enter this command with the search string you would like to find and this command lists all files containing that string

ps x -Ho pid,args

lists all of the processes running

find / -name gcc

finds all folders named gcc


sed '/$/,/' /home/Desktop/jessirae > /home/Desktop/jessirae2

places a comma at the end of each line


paste -sd '\0' - /home/Desktop/jessirae2 > /home/Desktop/jessirae3

The NEWLINE character of every line except the last line in each input file will be replaced with a separator

Ruby

"<a href=\"http://www.oldurl.com\">JessiRae.com</a>".

gsub(/(http?:\/{2})\S+\.(\w+)(\S+)/,"http://www.jessirae.com/blog/")

global substitution replaces all instances of some expression in a string with some other string or performs some function on that string


require 'open-uri'
....
open(url) {

      |page| page_content = page.read()

      page_content

    }

returns html from specified webpage

Ubuntu installed

My HP desktop was fried and so I replaced it with a linux box from walmart.com. It came with Linspire installed, but I immediately put Ubuntu on it… just to see what all of the hype was about.
