			<content:encoded><![CDATA[<div class='snap_preview'><br /><p>The following is the release announcemnet from Jeremy White of CodeWeavers (CrossOver):</p>
<p><em>Hi Folks,</em></p>
<p><em>I am pleased to announce that we have shipped CrossOver 7 for both Macintosh and Linux.  New in Version 7 is support for Microsoft Office 2007, dramatically improved support for Outlook 2003 and Internet Explorer 6,  and a broad range of improvements that should bring improvements to all Windows applications.</em></p>
<p><em>For our Linux customers, it also brings expanded support for most Adobe programs, with Photoshop CS and CS2 working particularly well.</em></p>
<p><em>For our Macintosh customers, this release also brings a change in our product mix.  We are now providing &#8220;CrossOver Mac Standard&#8221; and &#8220;CrossOver Mac Professional&#8221;.  The new Standard product will mirror</em></p>
<p><em> the <a href="http://www.codeweavers.com/products/cxlinux/?ad=52">Linux Standard product</a>, in that it will be a lower priced product with more basic support and no multiple user support.  The new CrossOver Mac Professional product replaces the existing CrossOver Mac product.  It continues to have our best support, support for multiple users, and, <a href="http://www.codeweavers.com/products/cxmac/?ad=52">CrossOver Mac Pro</a> continues to come with a complimentary copy of CrossOver Games. If you have purchased CrossOver Mac in the past, you have been automatically upgraded to a CrossOver Mac Pro license.</em></p>
<p><em>Finally, another major benefit of 7.0 is that it includes many of the elements of Wine 1.0, which was also released today. This is a major milestone for us, and for the Wine project.  Our many years of work, and your many years of supporting our work, have enabled us to help bring Wine to this milestone.  I am very proud to have been part of this, and very grateful for all the support of our customers, advocates, and fellow Wine developers.</em></p>
<p><em>If you are an existing CrossOver customer with an active support entitlement, you can visit our web site to download this latest version: <a href="http://www.codeweavers.com/?ad=52">www.codeweavers.com</a><br />
You will need to log in with the email and password that you used when<br />
purchasing CrossOver.  Please write to <a href="https://mail.google.com/mail?view=cm&amp;tf=0&amp;ui=1&amp;to=info@codeweavers.com" target="_blank">info@codeweavers.com</a> if you need help with this process.</em></p>
<p><em>Thanks again for all your support, and I hope that you enjoy CrossOver 7!</em></p>
<p><em>Cheers,</em></p>
<p><em>Jeremy White<br />
CEO<br />
CodeWeavers</em></p>
<p>&#8212;<br />
Version 7.0 Changelog:</p>
<p><strong>New application support:</strong></p>
<ul>
<li> Office 2007 (Including Word, Excel, PowerPoint, and Outlook)</li>
<li>Adobe Photoshop CS and CS2</li>
<li>Added support for the &#8220;Compatibility Pack for the 2007 Office system&#8221; so that Office 2003 can open Office 2007 documents</li>
</ul>
<p><strong>Bug fixes:</strong></p>
<ul>
<li><strong> </strong>Greatly improved online banking integration in Quicken 2007 and 2008</li>
<li>Greatly improved Outlook behavior, particularly with Exchange servers</li>
<li>Fixed service pack support for several versions of Office</li>
<li>Improved IE support in win2000 and winxp bottles (though win98 is still better)</li>
<li>Improved support for modern Linux distributions (especially Ubuntu)</li>
<li>Fixed a seriously horrible interaction with the Logitech Control Center documents from Office 2007</li>
<li>This version also includes countless Wine fixes and synchronizes with Wine 1.0.</li>
<li>Many small bugs should be fixed, and unsupported application behavior should be greatly improved.</li>

<p>Let&#8217;s get the easy way to do that.</p>
<p><span id="more-68"></span></p>
<p>Obs.: My post about <a href="http://menelkir.wordpress.com/2008/05/22/lvm-on-ubuntu-hardy-heron/" target="_blank">LVM on ubuntu</a> have a lot of info, so I&#8217;ll paste the important info about LVM here</p>
<p><strong>What is LVM?</strong></p>
<p>LVM (Logical Volume Manager) is a great piece of software which allow you to deal with Logical Volumes. Using LVM, you are able to extend/reduce your filesystems which is pretty handy when you need more space.</p>
<p>A lot of distributions support out of the box in installer. Unfortunately, Hardy Heron doesn&#8217;t offer this on the Desktop Install CD.</p>
<p><!--more--></p>
<p><strong>What can I do with LVM?</strong></p>
<p>* Resize volume groups online by absorbing new physical volumes (PV) or ejecting existing ones.<br />
* Resize logical volumes online by concatenating extents onto them or truncating extents from them.<br />
* Create read-only snapshots of logical volumes (LVM1).<br />
* Create read-write snapshots of logical volumes (LVM2).<br />
* Stripe whole or parts of logical volumes across multiple PVs, in a fashion similar to RAID0.<br />
* Mirror whole or parts of logical volumes, in a fashion similar to RAID1.<br />
* Move online logical volumes between PVs.<br />
* Split or merge volume groups in situ (as long as no logical volumes span the split). This can be useful when migrating whole logical volumes to or from offline storage.</p>
<p><strong>What can&#8217;t I do with LVM?</strong></p>
<p>* LVM does not provide parity-based redundancy across LVs, as with RAID4, RAID5 or RAID6. This functionality is instead provided by Linux metadisks, which can be used as LVM physical volumes.<br />
* Converting regular filesystems into LVM filesystems online (you also can copy the stuff to a logical volume).</p>
<p><strong>Implementation</strong></p>
<p>LVM keeps a metadata header at the start of every PV, each of which is uniquely identified by a UUID. Each PV&#8217;s header is a complete copy of the entire volume group&#8217;s layout, including the UUIDs of all other PV, the UUIDs of all logical volumes and an allocation map of PEs to LEs. This simplifies data recovery in the event of PV loss.</p>
<p>In the 2.6-series Linux kernels, the LVM is implemented in terms of the device mapper, a simple block-level scheme for creating virtual block devices and mapping their contents onto other block devices. This minimizes the amount of relatively hard-to-debug kernel code needed to implement the LVM. It also allows its I/O redirection services to be shared with other volume managers (such as EVMS). Any LVM-specific code is pushed out into its user-space tools, which merely manipulate these mappings and reconstruct their state from on-disk metadata upon each invocation.</p>
<p>To bring a volume group online, the &#8220;vgchange&#8221; tool:</p>
<p>1. Searches for PVs in all available block devices.<br />
2. Parses the metadata header in each PV found.<br />
3. Computes the layouts of all visible volume groups.<br />
4. Loops over each logical volume in the volume group to be brought online and:<br />
1. Checks if the logical volume to be brought online has all its PVs visible.<br />
2. Creates a new, empty device mapping.<br />
3. Maps it (with the &#8220;linear&#8221; target) onto the data areas of the PVs the logical volume belongs to.</p>
<p>To move an online logical volume between PVs, the &#8220;pvmove&#8221; tool:</p>
<p>1. Creates a new, empty device mapping for the destination.<br />
2. Applies the &#8220;mirror&#8221; target to the original and destination maps. The kernel will start the mirror in &#8220;degraded&#8221; mode and begin copying data from the original to the destination to bring it into sync.<br />
3. Replaces the original mapping with the destination when the mirror comes into sync, then destroys the original.</p>
<p>These device mapper operations take place transparently, without applications or filesystems being aware that their underlying storage is moving.</p>

http://sourceware.org/lvm2/<br />
http://www.gentoo.org/doc/en/lvm2.xml</p>
<p><strong>Requirements</strong></p>
<p>* Gentoo 2007.0 livecd/livedvd or any other distribution livecd able to load lvm modules and applications.</p>
<p><strong>Preparing</strong></p>
<p>1) Start dm-mod (if not started yet)</p>
<p><em>modprobe dm-mod</em></p>
<p>3) Redetect disks and/or start lvm stuff.</p>
<p><em>vgscan<br />
vgchange -a -y<br />
</em></p>
<p><strong>Preparing Disks</strong></p>
<p>Let&#8217;s create a boot partition outside of LVM and all the rest for LVM (120Mb for /boot in 2*40Gb hardisks).</p>
<p><em><br />
$ sudo fdisk /dev/sda</em></p>
<p><em>The number of cylinders for this disk is set to 4865.<br />
There is nothing wrong with that, but this is larger than 1024,<br />

Using default value 1<br />
Last cylinder or +size or +sizeM or +sizeK (1-4998, default 4998):<br />
Using default value 4998</em></p>
<p><em>Command (m for help):t<br />
Partition number (1-4): 2<br />
Hex code (type L to list codes): 8e</em></p>
<p><strong>Formating Partitions</strong></p>
<p>1) Format /boot partition<br />
<em>$ sudo mke2fs /dev/sda1</em></p>
<p>2) Create physical volumes for LVM</p>
<p><em>$ sudo pvcreate /dev/sda2<br />
$ sudo pvcreate /dev/sdb1<br />
</em></p>
<p>3) Create volume group (I&#8217;ll use rootvg, like AIX)&#8230;</p>
<p><em>$ sudo vgcreate rootvg /dev/sda2</em></p>
<p>4) &#8230;then add the second physical volume</p>
<p><em>$ sudo vgextend rootvg /dev/sdb1</em></p>
<p>5) Create the logical volumes.</p>
<p><em>$ sudo lvcreate -n rootlv -L 15G rootvg<br />
$ sudo lvcreate -n varlv -L 5G rootvg<br />
$ sudo lvcreate -n homelv -L 30G rootvg<br />
$ sudo lvcreate -n usrlv -L 15G rootvg</em></p>
<p>6) Now you&#8217;re able to *see* this logical volumes in Ubuntu Installer.</p>
<p>7) After installation ends, don&#8217;t reboot yet. Mount your logical volumes, proc and dev.</p>
<p><em>$ sudo mount  /dev/rootvg/rootvg-rootlv /mnt<br />
$ sudo mount  /dev/rootvg/rootvg-usrlv /mnt/usr<br />
$ sudo mount  /dev/rootvg/rootvg-varlv /mnt/var<br />
$ sudo mount  /dev/rootvg/rootvg-homelv /mnt/home<br />
$ sudo mount -t proc proc /mnt/proc<br />
$ sudo mount -o bind /dev /mnt/dev</em></p>
<p>You know the rest&#8230; and don&#8217;t forget to put LVM support on kernel.</p>

<p>LVM (Logical Volume Manager) is a great piece of software which allow you to deal with Logical Volumes. Using LVM, you are able to extend/reduce your filesystems which is pretty handy when you need more space.</p>
<p>A lot of distributions support out of the box in installer. Unfortunately, Hardy Heron doesn&#8217;t offer this on the Desktop Install CD.</p>
<p><span id="more-67"></span></p>
<p><strong>What can I do with LVM?</strong></p>
<p>* Resize volume groups online by absorbing new physical volumes (PV) or ejecting existing ones.<br />
* Resize logical volumes online by concatenating extents onto them or truncating extents from them.<br />
* Create read-only snapshots of logical volumes (LVM1).<br />
* Create read-write snapshots of logical volumes (LVM2).<br />
* Stripe whole or parts of logical volumes across multiple PVs, in a fashion similar to RAID0.<br />
* Mirror whole or parts of logical volumes, in a fashion similar to RAID1.<br />
* Move online logical volumes between PVs.<br />
* Split or merge volume groups in situ (as long as no logical volumes span the split). This can be useful when migrating whole logical volumes to or from offline storage.</p>
<p><strong>What can&#8217;t I do with LVM?</strong></p>
<p>* LVM does not provide parity-based redundancy across LVs, as with RAID4, RAID5 or RAID6. This functionality is instead provided by Linux metadisks, which can be used as LVM physical volumes.<br />
* Converting regular filesystems into LVM filesystems online (you also can copy the stuff to a logical volume).</p>
<p><strong>Implementation</strong></p>
<p>LVM keeps a metadata header at the start of every PV, each of which is uniquely identified by a UUID. Each PV&#8217;s header is a complete copy of the entire volume group&#8217;s layout, including the UUIDs of all other PV, the UUIDs of all logical volumes and an allocation map of PEs to LEs. This simplifies data recovery in the event of PV loss.</p>
<p>In the 2.6-series Linux kernels, the LVM is implemented in terms of the device mapper, a simple block-level scheme for creating virtual block devices and mapping their contents onto other block devices. This minimizes the amount of relatively hard-to-debug kernel code needed to implement the LVM. It also allows its I/O redirection services to be shared with other volume managers (such as EVMS). Any LVM-specific code is pushed out into its user-space tools, which merely manipulate these mappings and reconstruct their state from on-disk metadata upon each invocation.</p>
<p>To bring a volume group online, the &#8220;vgchange&#8221; tool:</p>
<p>1. Searches for PVs in all available block devices.<br />
2. Parses the metadata header in each PV found.<br />
3. Computes the layouts of all visible volume groups.<br />
4. Loops over each logical volume in the volume group to be brought online and:<br />
1. Checks if the logical volume to be brought online has all its PVs visible.<br />
2. Creates a new, empty device mapping.<br />
3. Maps it (with the &#8220;linear&#8221; target) onto the data areas of the PVs the logical volume belongs to.</p>
<p>To move an online logical volume between PVs, the &#8220;pvmove&#8221; tool:</p>
<p>1. Creates a new, empty device mapping for the destination.<br />
2. Applies the &#8220;mirror&#8221; target to the original and destination maps. The kernel will start the mirror in &#8220;degraded&#8221; mode and begin copying data from the original to the destination to bring it into sync.<br />
3. Replaces the original mapping with the destination when the mirror comes into sync, then destroys the original.</p>
<p>These device mapper operations take place transparently, without applications or filesystems being aware that their underlying storage is moving.</p>

http://sourceware.org/lvm2/</p>
<p><strong>Requirements</strong></p>
<p>* Ubuntu install LiveCD 8.04.<br />
* Internet connection or lvm2 deb package.<br />
* Free Disk Space</p>
<p><strong>Preparing</strong></p>
<p>1) Install LVM2 Package</p>
<p><em>sudo apt-get install lvm2</em></p>
<p>2) Start dm-mod</p>
<p><em>sudo modprobe dm-mod</em></p>
<p>3) Redetect disks</p>
<p><em>sudo partprobe</em></p>
<p><strong>Preparing Disks</strong></p>
<p>Let&#8217;s create a boot partition outside of LVM and all the rest for LVM (120Mb for /boot in 2*40Gb hardisks).</p>
<p><em><br />
$ sudo fdisk /dev/sda</em></p>
<p><em>The number of cylinders for this disk is set to 4865.<br />
There is nothing wrong with that, but this is larger than 1024,<br />
and could in certain setups cause problems with:<br />
1) software that runs at boot time (e.g., old versions of LILO)<br />
2) booting and partitioning software from other OSs<br />
(e.g., DOS FDISK, OS/2 FDISK)</em></p>
<p><em>Command (m for help): n<br />

<p><em>Calling ioctl() to re-read partition table.</em></p>
<p><em>WARNING: Re-reading the partition table failed with error 16: Device or resource busy.<br />
The kernel still uses the old table.<br />
The new table will be used at the next reboot.<br />
Syncing disks.</em></p>
<p><em>$ sudo fdisk /dev/sdb</em></p>
<p><em>The number of cylinders for this disk is set to 4998.<br />
There is nothing wrong with that, but this is larger than 1024,<br />
and could in certain setups cause problems with:<br />

Hex code (type L to list codes): 8e</em></p>
<p><em>$ sudo partprobe </em></p>
<p><strong>Formating Partitions</strong></p>
<p>1) Format /boot partition<br />
<em>$ sudo mke2fs /dev/sda1</em></p>
<p>2) Create physical volumes for LVM</p>
<p><em>$ sudo pvcreate /dev/sda2<br />
$ sudo pvcreate /dev/sdb1<br />
</em></p>
<p>3) Create volume group (I&#8217;ll use rootvg, like AIX)&#8230;</p>
<p><em>$ sudo vgcreate rootvg /dev/sda2</em></p>
<p>4) &#8230;then add the second physical volume</p>
<p><em>$ sudo vgextend rootvg /dev/sdb1</em></p>
<p>5) Create the logical volumes.</p>
<p><em>$ sudo lvcreate -n rootlv -L 15G rootvg<br />
$ sudo lvcreate -n varlv -L 5G rootvg<br />
$ sudo lvcreate -n homelv -L 30G rootvg<br />
$ sudo lvcreate -n usrlv -L 15G rootvg</em></p>
<p>6) Now you&#8217;re able to *see* this logical volumes in Ubuntu Installer.</p>
<p>7) After installation ends, don&#8217;t reboot yet. Mount your logical volumes, proc and dev.</p>
<p><em>$ sudo mount  /dev/rootvg/rootvg-rootlv /mnt<br />
$ sudo mount  /dev/rootvg/rootvg-usrlv /mnt/usr<br />
$ sudo mount  /dev/rootvg/rootvg-varlv /mnt/var<br />
$ sudo mount  /dev/rootvg/rootvg-homelv /mnt/home<br />
$ sudo mount -t proc proc /mnt/proc<br />
$ sudo mount -o bind /dev /mnt/dev</em> <img src='http://s.wordpress.com/wp-includes/images/smilies/icon_cool.gif' alt='8)' class='wp-smiley' /> Copy your resolv.conf to filesystem.</p>
<p><em>$ sudo cp /etc/resolv.conf /mnt/etc/</em></p>
<p>9) Chroot</p>
<p><em>$ sudo su -<br />
# chroot /mnt/ /bin/bash<br />
# source /etc/profile</em></p>
<p>10) And now, install lvm2 and re-install grub</p>
<p><em># apt-get install lvm2<br />
# grub-install /dev/sda</em></p>
<p>11) Now you can reboot.</p>

			<content:encoded><![CDATA[<div class='snap_preview'><br /><p>Yes.. I know theres a lot of office suites out there for linux.. the problem is: In my actual work, I *MUST* use the dammit OOXML for docs, spreadsheets, presentations and Visio for stuff. I personaly hate Office2007 but.. I just need it&#8230;</p>
<ul>
<li>Download and install crossover-game trial at codeweavers (yes, crossover games)</li>
<li>Install the last wine available (Ubuntu 8.04 have a good one, gentoo ~x86 too)</li>
<li> Download and install winetricks at http://www.kegel.com/wine/winetricks</li>
<li> Now, go to console and type winecfg to create your first wine configuration.</li>
<li> From winetricks, install this packages: dotnet11, dotnet20, gdiplus, msxml3, msxml4, msxml6, vcrun2005sp1 and vcrun2008.</li>
<li> Now, go to /home/&lt;youruser&gt;/.wine/drive_c/windows/system32 and rename rpcrt4.dll to something like rpcrt4.dll.bak</li>
<li> Copy /opt/cxgames/lib/wine/rpcrt4.dll.so to /home/&lt;youruser&gt;/.wine/drive_c/windows/system32/rpcrt4.dll (yes, without the .so).</li>
<li> Mount office cd with -o unhide option (I don&#8217;t know why, but if you automount, the cd will miss some files).</li>
<li> Go to directory of cdrom and type wine setup.exe</li>
<li> Now you can uninstall crossover trial, remove the rpcrt4.dll used and put the old one in this place (now office 2007 will work with the old one).</li>
</ul>
<p>Update 1: It&#8217;s a good one to install riched20 and riched30 to have a better look on fonts.<br />
Update 2: <a title="4j4x" href="http://4j4x.wordpress.com/" target="_blank">4j4x</a> translate this post to indonesian, check <a href="http://4j4x.wordpress.com/2008/04/10/menginstall-office-2007-di-linux-dengan-wine/" target="_blank">here</a><br />
Update 3: MS Project and MS Outlook doesn&#8217;t work (project claims to not being installed to current user, I think this is just a registry problem).<br />
Update 4: MS Visio and Office updates works as well.<br />
Update 5: Alain reports the .Net 1.1 asks for ie5 (this doesn&#8217;t occurs with me), but without the .net 1.1 the installation works.<br />
Update 6: I don&#8217;t know why but Powerpoint doesn&#8217;t work to everyone.<br />
Update 7: Portuguese version <a href="http://menelkirbr.wordpress.com/2008/06/10/instalando-o-office-2007-no-wine/" target="_blank">here</a></p>
<p>Thanks for all testing and reporting.</p>

			<content:encoded><![CDATA[<div class='snap_preview'><br /><p>Hi all</p>
<p>In the last days I think to make some simple script to make my backups (I have a TSM server in my company, but I&#8217;m not there all the time). So I create some simple stuff to make backups when I&#8217;m not on home or in my desk (Just simpel tars + rar + pass, without crypt, to send via net to my job or to some gmail fs-space-a-like).</p>
<p><span id="more-63"></span></p>
<p>My stupid script:<br />
<i></i></p>
<p><i>#!/bin/bash<br />
#<br />
# Syntax:<br />
# backup &lt;directory name&gt; &lt;password of rar file&gt;<br />
</i></p>
<p><i>name=backup-`date +%Y%m%d`<br />
echo $name</i></p>
<p><i>cd /home/<br />
tar cvpf $name.tar $1<br />
rar a -vt -p$2 $name.rar $name.tar</i><br />
<b></b></p>
<p><b>Gmail Space</b></p>
<p>Since my home backup is something like 200Mb, Im able to send my backup to some webspace, such as gmail. There&#8217;s a lot of gmailfs plugins/modules/software out there. Actually Im using via browser (cause Im able to use via proxy).</p>

And the reasons had convinced me to do the same.</p>
<p>One observation (I see this happen in more than one thinkpad model) :</p>
<p>I don&#8217;t know why, but Ubuntu linux eat lots of minutes to boot with a black screen, and when you use a encrypted /home, you&#8217;ll need to imaginate when type the password..</p>
<p>A: Just remove &#8220;splash silent&#8221; from the line <i>kernel</i> of your grub.</p>
<p>UPDATE: Just edit /etc/usplash.conf</p>

			<content:encoded><![CDATA[<div class='snap_preview'><br /><p>Since my job are freak about using office 2007 docs (and Im freak about not using windows), I just trying to find some way to do this inside linux.</p>
<p><span id="more-61"></span><br />
I notice that Office 2007 are unable to finish the install in wine, so, my first try is installing Office 2003 under wine. All is fine, but when I try using the the patch to make office 2003 open 2007 files, I see that this doesn&#8217;t work at all (when the installs finish, Im unable to open emulated office again, or, the bad of them, the patch doesn&#8217;t work at all).</p>
<p>VirtualBox also isn&#8217;t an option, WindowsXP + Office 2007 eats something like 10-20Gb, since my T43 have only 40Gb of hard disk.. and things come VERY slow.. Im able to install and work in some way, but unable to work fine&#8230;</p>
<p>Someone there knows something to help me? I think Im stucked in a bad way&#8230;</p>
<p>Obs.: Just to say, openoffice isn&#8217;t an option. Just try to make some &#8220;advanced formating in Office 2003&#8243;, open in openoffice, try to modify something, and try to open in 2003 again. Yuk!!</p>
