Run Linux From USB Flash / Pen Drive

If you wanna run Linux any time, any place, any computer, try USB device. Here's what to do with popular distributions like Puppy Linux, Ubuntu, and Fedora, so you can boot up directly from your thumb drive:

Most of the time, Linux is run from either an installation on a hard drive or a live CD/DVD distribution. The first is fast, but not very portable; the second can be run anywhere you have a computer and a CD drive with boot access, but typically isn't very fast. Over the last few years, though, we've seen the emergence of something that combines the speed of a hard drive install with the convenience of a live CD: running Linux from a USB flash drive.

Canonical Ltd. and Red Hat, Inc. today announced the inclusion of OpenJDK-based implementations in Fedora 9 and Ubuntu 8.04 Long Term Support (LTS) Server and Desktop editions, furthering the promise of Sun's open source Java technology initiative.

In addition, the NetBeans 6.0 Integrated Development Environment (IDE) () is being delivered as part of the Ubuntu 8.04 LTS release and Canonical has certified Ubuntu 8.04 LTS Server Edition on several Sun x86 systems.

Sun Press Release : Open Source Java Technology Debuts In GNU/Linux Distributions

You can install latest Ubuntu Linux 8.04 under Windows Vista / XP without creating a new parition with a new tool called Wubi. It is a Ubuntu installer for Windows users that will bring you into the Linux world with a single click. Wubi allows you to install and uninstall Ubuntu easily. This blog post covers basic installation:

With the latest release of the popular Linux-based operating system, Ubuntu Hardy Heron, the installation process just got easier for Windows users who wish to try out an alternative to Vista or XP. Even .NET developers who are looking out on trying the Mono project (the .NET platform for Linux-based operating systems) can benefit from it. All this is possible thanks to a little Windows utility called Wubi, which is an installer for Ubuntu.

Sun Looks To Open Source The Rest of Java

Sun is planning to remove the last reaming restrictions on Java to make it completely open source.

By freeing these up, Java can be fully open-source and thus be packaged more easily with Linux distributions. In conjunction with this activity, Sun is talking with Linux distributors, including OpenSuse, Ubuntu and Fedora to have them offer an updated version of OpenJDK, which constitutes the open-source Java platform. Sun plans to offer the updated OpenJDK soon and clear the last few encumbrances later.

Ubuntu 'reaping Linux dividend'

Red Hat and Novell decided not to challenge Microsoft on desktop PCs. However, Canonical Ltd is getting ready to release a new version of Ubuntu on Thursday. According to Mark Shuttleworth:

The public perception of open source software is changing fast. French police force was currently deploying 50,000 Ubuntu-powered machines, while Spanish education authorities were rolling out 500,000 desktops with the OS. Hardy Heron also has improved support for multimedia, including photo editing, music sharing and video playback. It's a favorite version of Linux both for specialists and one that specialists would recommend to a cousin, aunt or uncle who want to have a stable desktop internet experience. There are other versions of Linux that are better for a particular purpose - but Ubuntu strives to be a general platform that is secure and self-maintained.

Flickrfs is a virtual filesystem which mounts on your linux machine like any other partition. Once mounted, it retrieves information about your photos hosted on your flickr account, and shows them as files. You can now easily copy photos from your local machine to this mount, and it will automatically upload them to your flickr account. Similary, you can copy the files from your mount to your local machine, and it will download your images from flickr.
