Is there a standard name for the "standard" computer screw?
I have the unfortunate task of writing a technical document, and I know the government is a stickler for unnecessary detail. Is there standard name for the standard computer screw? Also, what is the name of the standard disk drive screw?
Best way to transfer files over a LAN between two Linux computers
I want to transfer files (a music folder) between two Linux computers. After searching for the best way to do this, I've seen that there are lots of ways of doing this. I know this has been asked a lot, everywhere and all the time. The main problem with this is that there is no clear, recent consensus on one best way to do this task in 2011 for Linux beginners (even depending on some parameters). So in the spirit of the Stack Exchange websites, I want this not to be related to my particular situation, but more of a guide to others as well on how to transfer files between two Linux computers over a local network. I think a wiki would be useful for many. Here's what I found so far: ssh sshfs scp sftp nfs samba giver What is the easiest? Most flexible? Simplest? Best solution? What are the pros and cons of each? Are there other (better) options? What are the parameters in choosing the best method (solution might depend on number of files, filesize, easiness vs. flexibility, ...)?
How to find a directory on linux?
I have a VPS with Suse Linux 10.3. I've logged in via SSH/putty and am trying to find where my web files are located. Since I'm uploading via FTP in a directory called httpdocs, I assume that this directory exists somewhere. My google searches have taught me to do this, go to my root directory and type: but it says "No such file or directory". How can I find this directory?
How to install the real Firefox on Debian?

What's the maximum typical speed possible with a USB2.0 drive?
I'm getting only 30MB/sec between my computer and a USB drive, despite the fact that USB 2.0 supports 480Mb/sec (or 60MB/sec) transfers. (Therefore, I'm only getting half the rated speed) Is there something present in the USB standard which should result in such half apparent speeds?
How can I change to the previous directory instead of going up?
I currently spend a lot of my working hours moving back and forth between two paths which are very far down the tree and divert from each other at root. It strikes me that my life would be a lot easier if there was an argument for that takes the user to the last directory they were in. That is, if I'm in: and then type: I would like to be able to go back to the first directory without having to type the whole path again. The memory key does not cut it since I use enough commands in each place that it's just as difficult to go back and find the path I want as it is to type it myself. Is there a short command that would just let me go to the previous directory?
What are some options for transferring large files without using the Internet?
My employer's Internet connection is extremely slow. It's $6,000 a month, 9 Mb, bonded T1, shared by over 150 users. It's not untypical to see regular file transfer speeds of 20-100 KBps. And that was after I convinced upper management to upgrade - before it was $3,000 a month for 3Mb. There are no other carriers in the area with better prices or speeds. When I need to download a large file (which is frequently), I drive 40 miles back home, use my $60 a month 20 Mb FiOS connection, download the file in ten minutes, and drive back in less time than it would take me to just download the file at work (this is efficient for files greater than 500 megabytes, depending on the congestion of the network). After more than a year doing this and more and more frequent downloads, I'm at my wits' end. I am seriously contemplating raising carrier pigeons to fly back and forth between my home and office to transfer the files. Assuming a pigeon is carrying a 16 GB MicroSD card and can fly at a speed …
Is there a way to allow continuous scrolling in Adobe Reader?
I am having to read through a MASSIVE (1000+ page) PDF specification in Adobe Reader. It has always bugged me that if you scroll to the edge of a page, the Reader automatically jumps to the top of the next page. Is there a way to cut this functionality off so that as I'm scrolling, the bottom of the current page has a minimal space, and the next page continually scrolls into view, rather to jump in and take over the full display area? I know that Microsoft Word can behave this way. Is there a setting in Adobe Reader 10, or higher, that I can change that will allow continuous document scrolling?
How to copy multi-line text from Excel without quotes?
When you create a multi-line string in an excel cell (by using Alt-Enter), if you copy that cell to a text editor, excel will automatically add double quotes (") around the full string, ie: When you copy just the column with values to a text editor, we get: How can I tell excel not to add the quote around multi-line text when copying from excel?

Linux / OS X tar incompatibility – tarballs created on OS X give errors when untarred in Linux
When I tar up files on my Macbook and untar them in Linux, I repeatedly get the following warnings/errors: Fortunately, this does NOT affect the files stored in the archive, which are restored perfectly. However, it does cause problems in a number of scenarios, especially when dealing with build processes where the non-zero failure code returned by 'tar' causes builds and installs to stop unnecessarily. How can I get OS X to build tar files that play nicely with the rest of the Linux world? Also, for bonus points, there exists a publicly distributed tar file with these issues. Is there any way to get Linux to handle the tar file gracefully without changing the way it was originally compressed?
Formatting a comma-delimited CSV to force Excel to interpret value as a string
I've been searching around for a while trying to figure out how to output a CSV file in such a way to force Excel to interpret the values as a string and not try to convert them to numbers or dates. e.g.: Excel tries to "intelligently" convert all these to its native date/number formats. Is there a way around that? EDIT: Clarified the intent of my question, sorry for confusion.

Inverting direction of mouse scroll wheel
Is there a way to make a mouse scroll wheel invert its direction? I'd like to scroll upwards and have that action scroll downwards and vice-versa. There is no setting on the Mouse control panel that makes this possible. Any pointers to a hack or a particular mouse model that has such a setting would be appreciated. I am using Windows 7.
How far will you get with an 'rm -rf /' command?
I've often wondered how far the system will actually get if you run . I doubt the OS would be able to erase itself (?) Bonus Question: After the command has been executed, will have removed itself? Update: I've tested this in a couple of the main unix distributions using VirtualBox and the answers describe exactly what happens. If given the correct parameters, rm will remove every physical bit of data on the disc. However, I ran into some issues when using a version of rm other than the GNU one. For example, I believe BusyBox has their own version and it doesn't let you remove as much as you potentially could. This question was a Super User Question of the Week.
