How to read Ext3/Ext4 linux partition from windows 7
The ext4 or fourth extended filesystem is a journaling file system for Linux, developed as the successor to ext3.
It was born as a series of backward compatible extensions to remove 64-bit storage limits and add other performance improvements to ext3.However, other Linux kernel developers opposed accepting extensions to ext3 for stability reasons and proposed to fork the source code of ext3, rename it as ext4, and do all the development there, without affecting the current ext3 users
Ext2Read is an explorer like utility to explore ext2/ext3/ext4 files. It now supports LVM2 and EXT4 extents. It can be used to view and copy files and folders. It can recursively copy entire folders. It can also be used to view and copy disk and file
You can download Ext2Read from here
Screenshot
Ext2Fsd is an ext2 file system driver for Windows 2000, XP, Vista. It’s a free software and everyone can distribute and modify it under GPL2.
Procedure o follow
Important Note:- When creating/formatting the ext4 filesystem, make sure to add “-O ^extent” which means disabling the “extent” feature bit. The following steps will not work if your ext4 filesystem still has “extent” feature enabled. ext2 and ext3 partitions should be fine.
First Download ext2fsd from here
Run the ext2fsd installer. During install, we recommend you uncheck the “enable write access” feature to safeguard against losing data in your Linux partitions.
Restart your Windows 7 PC and run the Ext2 Volume Manager from Start Menu.
Important Note:- Use these tools with your own risk if you don’t use them properly it will remove your linux partition data

IPCop - Firewall / Content Filter / Block Porn / Web Proxy Cache - Copfilter / AdvProxy / URL Filter
http://pc-addicts.com - I set this up one morning to help block certain types of content from reaching any of the computers in the house. Also, the other reason I set this up, was for the web proxy caching capabilities. Not only does the sites that are routinely visited come up quicker, but it also limits the amount of bandwidth that we use.
KVM vs. VMware: A Case Study
After a month of debate and experimentation, my employer has made the decision to use the open-source KVM virtualization infrastructure for migrating IT resources to a virtualized environment. Below, I discuss why we chose KVM over its (mostly proprietary) alternatives.
Until a couple years ago, the open-source community offered no real contender in the virtualization market. True, the qemu project has been around for a while, but qemu remains too inefficient for most production environments. Xen has also existed since 2003, but for a long time it only supported a limited set of guest operating systems, which did not include Windows until late 2005. As a result, proprietary virtualization products like VMware enjoyed a near-monopoly in the enterprise market until quite recently.
The rapid maturation of KVM, or ‘kernel-based virtual machine’, over the course of the last couple of years constituted the first open-source challenge to VMware. Integrated into the Linux kernel, KVM provides feature-rich and highly efficient virtualization.
My colleagues and I tested KVM (running on an Ubuntu 8.04 host) and ‘barebones’ VMware ESX server over the last several weeks. Ultimately, we decided KVM was a better fit for our needs based on the following considerations:
- Cost. Although our virtualization requirements are minimal–we need to run only two guest servers on a single host machine–VMware would have cost an astonishing amount of money. With features like VMware motion factored in, we were looking at a huge hit to the budget–and it didn’t help that VMware charges per CPU, not machine, regardless of whether all CPUs will actually be dedicated to virtualization. KVM is totally free, in both senses of the word, and offers functionality equivalent to VMware motion.
- Ease of deployment. Installing KVM on Ubuntu 8.04 is as simple as an apt-get. ESX server is also easy enough to install, but having to deal with licensing adds another layer of complication that we’d prefer not to face. KVM, of course, requires no license.
- Speed. Although I don’t have hard numbers, KVM-based virtual machines definitely ‘felt’ more responsive than those running on VMware. Our experience seemed to confirm Red Hat’s claim last fall that KVM can support five VMs for every three running on VMware on the same piece of hardware. It was also troubling that ESX server wasted upwards of 500 megabytes of memory–without any VMs running–on system overhead, while an Ubuntu server is a considerably more efficient host.
- Management. Apparently it never occured to VMware that systems administrators might be running Linux on their workstations. As a result, Windows is the only platform on which VMware’s graphical management infrastructure is supported. A Linux CLI client is available, but I’d like more options than that. KVM, in contrast, can be managed via the command line, via graphical interfaces (running either on the local machine or forwarded over ssh to a remote workstation) or through the Enomaly web interface.
Perhaps the single major downside of KVM is that it requires a bit more technical know-how than VMware to deploy effectively, since some features can only be configured via manual hacking of XML files. But as KVM and related tools continue to mature, expect that to change.
For IT staff interested in zero-cost, Linux-friendly, feature-rich and resource-efficient virtualization, KVM has become the way to go. If VMware wants to compete, it needs to rise from the laurels of its crumbling monopoly by innovating and lowering costs.

youtube-dl: download youtube videos in Ubuntu using command line
If you use Ubuntu (or other Linux distribution) and you wish to download some video from youtube.com into .flv file you can try using youtube-dl
command line utility. It just downloads videos without any online applications, converters or etc. Type the following command in terminal to get it installed:
sudo apt-get install youtube-dl
Let’s imagine you would like to download the following video: http://www.youtube.com/watch?v=2leg8mUE9rs (this is part of Military Parade at Red Square in Russia at 9th of May 2010). Just run youtube-dl download utility as follows:
youtube-dl http://www.youtube.com/watch?v=2leg8mUE9rs
and in a few minutes you will get 2leg8mUE9rs.flv file that could be viewed using almost any video player like my favorite one VLC.
