OLPC to scrap Linux for Windows

OLPC to scrap Linux for Windows

Huh?!? Apple offered OSX for free, but was declined for not being open source. Now they're going with Windows?!? Will OLPC = "One License Per Child" now? I don't really see the purpose of using a commercial OS, on a stripped down laptop, for third world countries, when it requires more resources and costs more. Ugh. In a somewhat shocking [...]

Adobe Air on Linux: A Security Nightmare

Adobe Air on Linux: A Security Nightmare

"Adobe Air is an application platform/framework which received some buzz recently. One of the most popular Twitter clients was written using Adobe Air. Air seems to make it relatively simple to write nice looking cross platform applications. Two weeks ago, Adobe Air was released for Linux and I gave it a try on my Debian Etch system. The results [...]

The BBC Reports on Ubuntu

HOWTO: Linux Crontab syntax, setup, and help

We've been showing people how to automate various tasks in Linux for quite a while now. Today, we would like to briefly show people how to automate tasks in Linux using Cron jobs. You can execute crontab if your name appears in the file /usr/lib/cron/cron.allow. If that file does not exist, you can use crontab if your name does not appear in [...]

UPDATE: With Vista breached, Linux unbeaten in hacking contest

UPDATE: With Vista breached, Linux unbeaten in hacking contest

Does anybody know what distribution was used? Something like RedHat or Fedora is pretty significantly hardened right "out of the box", where there are other distros that aren't as locked-down. The MacBook Air went first; a tiny Fujitsu laptop running Vista was hacked on the last day of the contest; but it was Linux, running on a Sony [...]

Revolution OS: Documentary of Linux

My favorite quote: Giving the Torvalds Award to the Free Software Foundation is like giving the Han Solo award to the rebel fleet. I think many of you are not aware of how deep that analogy goes. http://video.google.com

What’s This “Linux Thing” and Why Should I Try It?

What’s This “Linux Thing” and Why Should I Try It?

Lately, Linux has been receiving quite a bit of notice. Between the ASUS EeePC, the One Laptop Per Child project, Dell's new Ubuntu line, Intel's Classmate PC, and Everex's Green PC, Linux has been getting a lot of attention from computer manufacturers. It seems every new computer in the last year has had Linux, but to most people that doesn't [...]

HOWTO: Recover Deleted Files on an ext3 File System

HOWTO: Recover Deleted Files on an ext3 File System

After a classic 'rm -rf ~' on ext3, Carlo Wood succeeded in recovering most of his data. Here's how... "It happens to everyone sooner or later: a split second after you hit Enter you realize your mistake, but it's too late; you just deleted a valuable file or directory for which no backup exists. Or maybe you have a backup, but it's a month old... [...]

Wal-Mart shoves Linux PCs off store shelves, not web site

Wal-Mart shoves Linux PCs off store shelves, not web site

Wal-Mart's experiment with selling cheap Linux-based PCs in its stores has apparently come to a close. Starting last October, the retail giant stocked desktops from the Green PC line manufactured by Everex. That stock ultimately sold out, but Wal-Mart has apparently decided not to refresh it. The Associated Press quotes a company spokesperson, [...]

Disk encryption in Fedora: Past, present, and future

Disk encryption in Fedora: Past, present, and future

These days, data is mobile. Every day, sensitive corporate data leaves a company’s headquarters on a flash drive or an employee’s laptop. Regardless of where it is going, mobile data can be an I.T. department’s worst nightmare. In fact, the 2006 “CSI/FBI Computer Crime and Security Survey,” a joint effort by [...]

HOWTO: Making a USB Key Bootable in Linux

HOWTO: Making a USB Key Bootable in Linux

When I needed to make a USB key (aka. USB pen drive, USB memory stick, whatever) bootable under Linux I found there was a number of pages on the Internet that listed the steps needed. Some of these pages required you to do some steps from DOS and/or used the syslinux command. I did not want to boot DOS in order to get the job done. I wanted to [...]

Local root exploit in kernels 2.6.17 to 2.6.24.1

There is a new local root exploit found in linux kernels 2.6.17 to 2.6.24.1. Here's a proof-of-concept, which basically works as a "passwordless su". I have tested the exploit on a few systems I manage, and it just plain works on a number of them. The distros I have around that are vulnerable are: Fedora 8 CentOS 5/5.1 (and therefore [...]

JVC MiniNote XP5230GB next to a Asus eeePC 4G

JVC MiniNote XP5230GB next to a Asus eeePC 4G

Asus use to make a laptop called the s200, also known as the JVC MiniNote or Victor Interlink, which came with a 8.9 inch screen at 1024x600 resolution. Placing a JVC Mininote xp5230 side by side with an Asus eeePC: They're practically the same size, and it was very surprising that Asus didn't go with the 8.9" screen originally, but I guess it all [...]

HOWTO: Setup Encrypted Partitions in Linux

HOWTO: Setup Encrypted Partitions in Linux

To start out we need free space on a drive that isn’t partitioned, or enough patience to resize an existing one. Just about everything here needs root privileges, since we’re working with filesystems. It would be easiest to start a root terminal with su -, then enter your password.First, we install the tools to get the encrypted [...]

Bash Batch Image Processing Script

Bash Batch Image Processing Script

Actually, it's just a simple (well, somewhat simple) set of bash functions all put together in one script with a menu (of sorts) to help you work on batches (entire directories) of images, all at once. I do some web design, and I like to take digital pictures, and have thousands of them. While uploading images to some fancy photo gallery software [...]

Write an Online Bulk Image Downloader Using BASH

Write an Online Bulk Image Downloader Using BASH

So my girlfriend tells me that I need to download several large image files from a photographer's website. I manage her online portfolio/website so I'm used to these types of requests... but this time I was going to find a better way to "leech them all." So anyway, she IM's me the URL for her most recent shoot... I was greeted by a nice default [...]

OpenOffice 3 has PDF import, native Aqua UI

  There’s been quite a bit of buzz recently after it was announced that OpenOffice 3 was due in September. It seems, however, most people still aren’t aware of what’s in store. We love OpenOffice.org, hereby referred to as OpenOffice like normal people do. We like the fact it does pretty much everything we need for [...]
