I'm working on a Linux distro, and it seems like Anaconda and Ubiquity aren't working for my needs.
Are there any precautions one should take when coding an installer for a whole system? I was thinking to just create a graphical copy and paste application with configuration, as my base system is...

Ok, I have Ubuntu installed but I want to install Windows also (dual-boot). Problem is, I don't have a free partition. I have my root partition (15 GB), and my /home partition (300 GB). The home partition has about 50 GB free space, and it's formatted reiserfs. I've heard about tools like resize_...
@MichaelMrozek Sounds appropriate to me. The guy is not even looking for an answer any more, and it doesn't really fit the QnA format anyway. I don't see what people stand to learn from the current form.

I am using pdftk to rearrange pages of a pdf file with bookmarks/outlines, but after that, the output file lost the bookmarks of the original.
My command is pdftk in.pdf cat 1-22 43 23-42 44-end output out.pdf.
I was wondering how I could keep bookmarks while rearrange pages?
Usually in the table of content of a book, each line is for a chapter or section and ended with its page number, for example,

The cost of employing a programmer in my area is $50 to $100 an hour. A top end machine is only $3,000, so the cost of buying a truly great computer every three years comes to $0.50/hour. ($3000/(150 wks * 40 hours))
Do you need a top-end machine? No, the $3000 he...
I'm aware that I can use ethtool eth0/eth1/eth2 to check the existence of a NIC.
But I wonder where the files are on the machine that contain information of an existing interface, as I need to use the Ruby language to check for available NICs.

By getting metadata from some pdf files with bookmarks by pdftk, I observe the format of bookmarks in pdf metadata. So I am guessing that with pdftk, it is possible to add and edit bookmarks of a pdf file.
Here are three steps that I follow:
I firstly get the metadata (including bookmarks if ...
# which mkdir
/bin/mkdir
# which mkdi

How can I get the path of the e.g.: "mkdir"'s binary without knowing the name of the binary file? (command). So that which "mkdi" would output the "/bin/mkdir" too.
If I use "OpenBSD as my Desktop OS" then what are my choices if I need to run e.g.: a Linux Distribution, or a Windows (xp/7) in a Virtual Machine?
I know that the following apps are not available for OBSD:
- VirtualBox
- XEN
What are my choices in 2011? Or it's better to download the flash videos? (but there aren't any solutions to download every type of videos, only youtube..).
Or are there any "linux-emulations" for OBSD?
What do I need to install/configure to make an e.g.: youtube HTML5 page work? Install a browser that's supporting it by default, or I have to do other things to?

It really should be the one on SO that gets closed since it's OffTopic there anyway.
Also, if anybody wants to hack a quality control userscript into Lance's browser that won't let him post to SE sites with "e.g." anywhere in the post, that would be fine with me.
@Gilles It's telling me I have voted on that question too but there is only one vote pending. Does the system show you've voted even after votes expire?
At one time there were 3 or 4 votes on that question, so I think it's showing us the message because we did vote even if one or the other of our votes has timed out.
We have two confirmed cases on the U&L site where the sliding vote expiration system is mistakenly blocking the ability to vote even after votes have expired.
As a current example this question has one outstanding vote-to-close but both Gilles and I are seeing the "You have already voted" me...
@Tshepang No, although FHS does mention subdividing /home into various groups.
I really like the layout actually. I've taken it a step farther on my own systems and modified some things that would normally store in /var like mysql to use /home/services/mysql instead.
@Gilles Ya I know. I admin several systems that have alphabetical subdividions under /home and they are a freaking pain.
@Tshepang I don't think it's the depth that's a problem nearly so much as the breadth. A major part of the reason people aren't freaked out by the windows directory hierarchy is that the massive chaos of it is mostly hidden by a depth they don't even know is there.
