He released the code and now multiple sites have posted the tester. I do not know how reliable it is. To us lusers out here in the real world, the Internet and the sites we visit are black boxes. We have no way to know how safely they are handling our data. The sky is always falling.

Replace the Retiring Windows XP with Linux http://lxer.com/module/newswire/ext_link.php?rid=200744 If you're using Windows XP, it won't stop working. All this means is you won't get security patches or technical support anymore. So what should you do? You can continue using it, as you always have. Or, you can upgrade to Windows 8.1, the newest Windows, or Windows 7. Or switch to Linux. Let's look at the pros and cons.

How to Create and Manage Btrfs Snapshots and Rollbacks on Linux (part 2) http://lxer.com/module/newswire/ext_link.php?rid=200352 In "How to Manage Btrfs Storage Pools, Subvolumes And Snapshots on Linux (part 1)" we learned how to create a nice little Btrfs test lab, and how to create a Btrfs storage volume. Now we're going to learn how to make live snapshots whenever we want, and how to roll the filesystem back to any point to any arbitrary point in time. This does not replace backups. But it's a great tool for quickly going back in time to a known good state. If you make a mess, for example a botched upgrade, this is a great way to keep your system up while you figure out what to do.

How to Manage Btrfs Storage Pools, Subvolumes And Snapshots on Linux (part 1) http://lxer.com/module/newswire/ext_link.php?rid=200069 Before we dive into using Btrfs, how is it pronounced? Lots of ways, like Bee Tree Eff Ess and Bee Tee Arr Eff Ess. That's too many syllables, so I favor Butter Eff Ess. It sounds nice, and everyone likes butter. In this two-part series we'll build a three-node Btrfs storage pool and learn all about managing snapshots, rollbacks, and subvolumes. Part 1 covers installing Btrfs, creating a simple test lab, creating a storage volume, and what commands to use to see what's in it. In Part 2 we'll create and manage subvolumes, snapshots and rollbacks.

How to Use the Super Fast i3 Tiling Window Manager on Linux http://lxer.com/module/newswire/ext_link.php?rid=199774 I've been a fan of tiling window managers ever since Windows 3.1. I know, Windows 3.1 wasn't very good for much actual work, but it did stacking and tiling windows rather nicely. The i3 tiling window manager is a nice modern tiling window manager for GNU/Linux and BSD operating systems. It supports tiling, stacking, tabs, virtual desktops, and multiple monitors. You can do almost everything from the keyboard, or mix up keyboard and mouse.

GRUB Legacy, Ext3/4 smackdown http://www.oreillynet.com/linux/blog/2008/05/grub_legacy_grub_2_and_ext34_s.html There are some "interesting" issues being raised due to an incompatibility between e2fsprogs and GRUB legacy that results in non-booting systems.

VLANs on Linux http://www.oreillynet.com/linux/blog/2008/01/vlans_on_linux.html <p>One thing that did not make it into the <a href="http://www.oreilly.com/catalog/9780596102487/">Linux Networking Cookbook</a> was a chapter on setting up VLANs (Virtual LANs). VLANs are logical subnetting, rather than being constrained by your physical Ethernet switches. Now that &#8220;smart&#8221; switches have gotten so inexpensive, VLANs are nice options even for small networks. For one example, you can run multiple subnets off a single switch. Parts 1 and 2 of my three-part series are here:</p> <p><a href="http://www.enterprisenetworkingplanet.com/netsysm/article.php/3723126">Do More With Less: Build a Linux VLAN</a><br /> <a href="http://www.enterprisenetworkingplanet.com/netsysm/article.php/3724316">Do More With Less: Port-Based VLANs</a></p> <p>Windows and Mac clients can also be members of your VLANs; part 3 will address tagged VLANs, routing and Linux client configuration.</p> <p>Part 3 runs next week.</p> O'Reilly Network MT Blog: Linux Carla Schroder O'Reilly and Associates, Inc. 2008-01-28T14:45-08:00 text/html en-us Copyright 2003, O'Reilly and Associates, Inc. Best Laptop Desk http://www.oreillynet.com/linux/blog/2008/01/best_laptop_desk.html <p>I finally broke down and ordered a <a href="http://www.lapgenie.com/">LapGenie</a>. I would have bought one a long time ago, but at $139 my inner cheapskate just couldn&#8217;t quite take the plunge. Well I finally did, and I&#8217;m glad. It&#8217;s lightweight, sturdy, and comfortable. It supports the weight of my laptop, adjusts to a useful range of heights and angles, and I can squirm and fidget all I want to without upsetting the computer. I use it all over the place- couch, bed, and outside chair when the weather permits.</p> <p>It seems to be well-made, so I expect many years of service. They have a 30-day money-back policy and a good warranty. It showed up five days after I placed the order- many thumbs up for the LapGenie.</p> O'Reilly Network MT Blog: Linux Carla Schroder O'Reilly and Associates, Inc. 2008-01-14T10:45-08:00 text/html en-us Copyright 2003, O'Reilly and Associates, Inc.
