How do I connect VLC to a known DLNA server?
I have VLC on my Mac and would like to connect to a DLNA server on my LAN but the server isn't showing up in VLC's UPnP auto-discovery UI. Given the IP address of the server how can I point VLC to it explicitly so it can be 'discovered'?
Get current folder name by a DOS command?
Is it possible to get the current folder name (not current directory path) by using a DOS command? If so, how? The closest I got was this but it doesn't do it: note: the above attempt was me attempting to tokenize the string and get the last token set as the CURR variable.
What are "build-essential" & "build-dep"?
I am researching how to install Ruby 1.9.1 in Xubuntu 10.04 and I came across the command build-essential and build-dep multiple times. Sometimes it is followed by packages and sometimes it is both preceded and post-ceded by packages. The 2 examples I am looking at are: sudo apt-get install build-essential zlib1g zlib1g-dev zlibc libruby1.9 libxml2 libxml2-dev libxslt-dev sudo apt-get build-dep ruby1.9 and sudo apt-get install ruby irb ri rdoc ruby1.8-dev libzlib-ruby libyaml-ruby libreadline-ruby libncurses-ruby libcurses-ruby libruby libruby-extras libfcgi-ruby1.8 build-essential libopenssl-ruby libdbm-ruby libdbi-ruby libdbd-sqlite3-ruby sqlite3 libsqlite3-dev libsqlite3-ruby libxml-ruby libxml2-dev
vim cut and paste history
When I'm 'cutting' in vim, I believe there are registers that keep a history of all the recent things I've cut. How do I access those registers? For example, let's say I cut each one of these words consecutively 'Hello' 'World' 'And' 'Vim' Note that I'm not actually saving these edits into particular registers, I'm just using 'd' four times consecutively.
How to save a mail into an .eml-file with Outlook?
Outlook Express and Thunderbird both support the .eml-file format. Somehow Outlook does not. Is there any way to save mails into into an .eml-file using Outlook (e.g. with the help of a plugin)?
What does "2>&1" do in command line?
I know that the sign is used for output redirection in the command line, but I'm having trouble finding something that explains the use of in the command line. For example:
How do I locate the MAC address of my computer?
I am unable to locate the MAC address in a new computer with Windows 7. I've tried in the console to which I got . I also tried . A screen flashed very briefly with what appeared to be the information, but it was not there long enough to read.
Using Ctrl-Tab to switch between tabs in Mac Terminal.app
How can I make Ctrl-Tab and Ctrl-Shift-Tab switch between tabs in Terminal.app on a Mac (OS 10.4 and 10.5 specifically)? This is how I switch tabs in Firefox and Aquamacs, and Command-Shift-[ and Command-Shift-] is too awkward to me. I am aware of this related question: How can I change the keyboard shortcut for switching tabs in Mac Terminal? And hence the Keyboard Shortcuts section of the System Preferences, but the dialog box for Keyboard Shortcuts doesn't seem to accept Ctrl-Tab in the Keyboard Shortcut field. Is there a special keyboard sequence for inputting tabs (with modifiers) into a dialog box field on a Mac? Is there any other method that would allow me to customize Terminal.app in the way I desire?

How are commercial DVD's burned?
I'm not talking about the DVD-R's here. When you buy retail software and DVD movies from the store for example, how is that DVD burned onto the original disc? What would I need if I want to burn those type of "commericial" discs? (Is there a special device similar to a DVD burner for example, for this?)
Can zipping a file break it?
I just asked someone to send me a zipped file. They declined, citing that zipping a file can break the fonts. I assumed zipping a file is perfectly reversible, hence why it is commonly used. I think the other person is incorrect. Is there any truth about zipping breaking its files' contents?

Can I uninstall something I installed via homebrew using homebrew?
Make Windows Task Scheduler alert me on fail
I have an automated script that pulls backups from my website to my local computer. This script could fail; once my server was down, another time I accidentally moved my script. How do I make Windows Task Scheduler tell me with the script fails (or doesn't run/not found)? I don't care if a prompt comes up, an email or something that appears on my desktop. I want to be notified if something goes wrong. On my server, crontab emails me about errors - which is great. I want something like that on my windows 7 local computer.
How do I convert a .PNG into a .ICO?
There's an image in the VS2010 stock icon pack which is only included as a PNG, which I would like to use as an ICO (I want XP and earlier users to see the icon). How can I convert the PNG into the ICO?
How to sync bookmarks across Google Chrome and Mozilla Firefox bookmarks?
How to sync bookmarks across Google Chrome and Mozilla Firefox bookmarks? As I currently understand, Google Chrome puts bookmarks separately from Google Bookmarks, which is accessible in Firefox by using Google Toolbar for Firefox. Right? So, how should I synchronize my browsers? I use Google Chrome as my primary browser. It works good and bookmarks are synchronized across a number of computers I'm using.

How do I list the groups that a UNIX user is a member of?
With I can list the users in a group. How can I do the opposite - that is, list all the groups that a user is a member of? (I need this to find the name of a group that I know a user who is a member of, but I don't know the group name...) Clarification: This question is complicated by the fact that I am not the system administrator, and that I don't have root permissions (far from it). Instead, I am part of a group of "moderators" that administrate a small part of the system - to be specific, the physics branch of the student union at my university's central IT system. Within our branch, we have a bunch of different access groups for people who are in charge of things. In this case, one of two people responsible for something (it doesn't matter what) have been replaced, and I was looking to examine the other user to find out what access rights I should give the replacement. I have now been able to solve the immediate problem (the new guy not being able to access a folder) by examining…
How to get back to insert mode in VIM when you accidentally hit C-x C-s
Given this vim session: How do I get back to insert/command mode again? (C-x C-s means Control-x Control-s, not sure if it's normal vi terminology for keyboard shortcuts) I know there's some way to get out of this and into insert/command mode again, but I just can't remember how and searching Google or superuser hasn't yielded me anything. This happens since I mostly use emacs, but I use vim for remote hosts where I don't have emacs installed. Occasionally I do this and I figured I should learn how to get out instead of just restarting the terminal every time.
Removing dead thunderflies stuck inside an LCD monitor
This summer my flat was "attacked" by hundreds of tiny thunderflies, some of which managed to get behind the screen of my LCD. A few of the cursed creatures went and died right in the middle of the display: And yes, this is real. Imagine my surprise when I saw one of these things crawling across the monitor, tried to swat the thing and realized it was inside! How do I go about removing them? I have tried tapping the screen and shaking it but to no avail. They are very annoying to look at because they look like groups of dead pixels, or even ( ) characters.
What does 'make install' do?
Moving from Windows to Linux, I am unable to understand the process of installing software in Linux. In Windows, when we run an installation file, it asks where you wish to install the program, most probably in program files folder only. Later, it edits the registry. This is called installation in Windows. What does 'installing software' in Linux mean exactly? Suppose I downloaded source code, configure it, and then build the binary using . Now it is just a binary, not a usable program yet. How is it going get 'installed' ? By ? And what does this command do, exactly?
