Why does the /winsxs folder grow so large, and can it be made smaller?
A Vista virtual machine I use only has a 10 GB virtual hard disk -- and I'm worried about it running out of space over time. I used TreeSize to check for the culprits.. And the primary culprit is that or "Windows Side-By-Side" folder. What is the Windows Side By Side folder? Well, that's explained pretty well here. All of the components in the operating system are found in the WinSxS folder – in fact we call this location the component store. Each component has a unique name that includes the version, language, and processor architecture that it was built for. The WinSxS folder is the only location that the component is found on the system, all other instances of the files that you see on the system are “projected” by hard linking from the component store. Let me repeat that last point – there is only one instance (or full data copy) of each version of each file in the OS, and that instance is located in the WinSxS folder. So looked at from that perspective, the WinSxS folder is reall…
Mac OS X: conventional places where binary files should live
I've downloaded an application that is a command-line application, and want to put it somewhere where I can run it from the command-line without having to type the path explicitly. What are the conventional paths used for something like this? ? Are there different options, one if I want it for all users, and one if I want it for just a particular user, like my administrator account? Or should I put it in its own directory under the Applications directory, and add it to the path? If so, which file controls where the path is set?

Display list of computers on a LAN in Linux
I'm a web dev who is trying to get a better handle on security. I'm trying to figure out a way (on Linux/Debian based distros) to list all computers on the same LAN my netbook is on. I tried "arp -n" but I don't feel it's a complete list, as my iPhone is on the same wi-fi router as my netbook, and that didn't come up. Is there some better way to get a full list of machines that are all sharing the same gateway?

Is there windows equivalent to the .bashrc file in linux?

How does Router know where to forward packet
If several computers with local addresses (192.168.0.#) are connected to a router and each computer opens a web browser and requests a page over HTTP, when these TCP:80 packets are sent out, the router switches the local address with the static IP of the router (i.e. Provider given IP) so the server can reply to the appropriate address. But how does the router know to which computer to forward the HTTP reply, since the TCP header does not contain the local IP address (does it?), and all computers are using port 80? Does this have anything to do with the MAC addresses? How exactly does this work?
How do I burn an ISO on a USB drive on Mac OS X?
what's the best way to get an ISO "burned" to a USB stick on a Mac? Restoring using Disk Utility does not work. The ISO is ubuntu mini.iso. It is the minimalist install ISO for installing ubuntu. It needs to be bootable on a PC. I am trying to install ubuntu on a PC that has no CD-ROM. The only other computer I have around is a macbook.
Turning off the cmd window beep sound
Is there a way to essentially mute the Beeping function of the Windows command shell? I'm working on a PowerShell script right now which ends up printing several lines of text to the screen. I'm working out a bug in the encoding logic. But every time I'm wrong my script will spew a bunch of random binary characters to the screen and eventually cause many annoying beeps. The failure is quite obvious without the beeps :)

How do I mount a network drive to a folder?
Does anyone know of a third party (or even windows native) solution to this simple problem? I want to map an internal network share on our windows server to a folder on each of the client machines in the network. I don't want to to use drive letters; I would just like to set up a folder on my drive that is actually a Windows share. For example, should actually point to . Is this possible? Is there any tool that does it? All clients are using Windows XP and Windows 7.

Are there solutions that can limit the CPU usage of a process?
I am using an old laptop and doing heavy processing that needs high CPU usage for a long time (~30mins - 2hours). When the process puts heavy load on CPU for a long time, CPU overheats and computer shuts down. I don't want to use a cooler/stand because I am carrying this laptop around and working outside home. Is there a way/application that I can limit CPU usage of a process in Windows? Note: Setting the priority of the process from task manager does not work. Note 2: Fans are clean.
How can I get (g)Vim to display the character count of the current file?
I like to write tutorials and articles for a programming forum I frequent. This forum has a character limit per post. I've used Notepad++ in the past to write posts and it keeps a live character count in the status bar. I'm starting to use gVim more and I really don't want to go back to Notepad++ at this point, but it is very useful to have this character count. If I go over the count, I usually end up pasting the post into Notepad++ so I can see when I've trimmed enough to get by the limit. I've seen suggestions that would help, but this only gives the character count via the current column index on the current line. This would be great if I didn't use paragraph breaks, but I'm sure you'd agree that reading several thousand characters in one paragraph is not comfortable. I read the help and thought that would work, but after looking over the format it uses I didn't see anything that gives a character count for the current buffer. I've seen that there are plugins that add this, but I'…
Google Chrome Auto-Close Download Bar

Arrange windows within the same application in the taskbar of Windows 7

Bluetooth Headphones sound terrible on Mac OS X?
I got a pair of Plantronics bluetooth headphones. Work great with my iPhone. Sounds terrible with my Mac, cuts out, sounds choppy, sounds mono to me. A co-worker tells me he has the same problem. BTW, I'm on Leopard, patched up. So question is: What is the deal? Is it fixable?
