This article is just for me to recall how to print envelopes.

Using LibreOffice, use the Insert —> Envelope menu.

• Addressee is the TO field.
• Set the paper to landscape.
• look at the print preview – move the location box as needed.
• Use the front feed for the Samsung printer.
• Insert the envelope with the print-side up with the normal fold opening from the center and down to the left of the printer. You will read the envelope from the right-hand side of the printer looking left.

If this helps someone else, I’d be shocked. OTOH, I don’t use paper envelopes very often, so having this written down somewhere means fewer throw way envelopes due to failed printing attempts.

Below is the 3rd of 6 questions from a reader. I definitely don’t have all the answers, but I’m not short on opinions. ;)

Q3: I intent (sic) to provide quite a lot of media to my internal network, if I choose for virtualisation, will the VMs be able to access the disk space outside of the container? I do not want to create TB size containers (or should I?). I will probably use the SMB protocol here.

duijf asks:

Q2: I read everywhere about Virtualisation, should I directly install packages to the base system to provide services, or should I virtualise all services? What are the advantages here?

Advantages of Virtualization

The list of advantages is long, but with those advantages comes a few disadvantages. I cannot hope to point out all the advantages, so I’ll limit it to just the main ones.

Sometime on Monday the database that we run our blog software on became corrupted to the point that accessing the blog wasn’t possible for hours, perhaps many, many hours.

I don’t know how long the error existed, just that I created a few new articles in the morning and didn’t check back until late afternoon to see the process eating 99.99% of the available CPU AND not serving any pages.

This weekend, my 3 yr old VirtualBox VDI storage for this, my primary virtual machine, was getting close to 100% filled. It was a 10G partition that started out as a 6.06 installation, then was upgraded to 8.04 and finally to 32-bit Ubuntu Server running 10.04. To get a GUI, I added LXDE a few minutes after the 10.04 upgrade about a year ago. So as I wanted to start a new development project leveraging PerlBrew to manage different versions of entire Perl versions, libraries and CPAN modules, I knew the little space remaining would not be enough.

I did a little research before I began. The web pages that I found seemed to be taking the long way around to solve a fairly easy issue. They wanted users to download some tool, which was completely unnecessary. Anyway, below the shortest, easiest, way to increase the available storage in a VDI-based virtual machine.

duijf asks:

I have a total of 5 quiet 5400RPM 1TB drives configured in a RAID5+1 array. I installed Ubuntu Server 10.04 onto LVM , inside the LVs JFS is used as the file-system. Is this good practice?

This morning I saw an email from a business associate. It contained a link to an article on LinkedIn. That article was actually hosted on mashup. The article was about Social Media Overload; he called it The Sharepocalypse. After reading a fairly long article pointing out all the issues with the different human interactions with the main social media providers, I wanted to add a comment. Oddly, I couldn’t unless I used either a twitter or facebook account to login.
