Displaying XML in the Chrome browser
I love the Chrome browser, but I use XML quite a lot in my development work and when I view it in Chrome I just get the rendered text. I know that the source view is slightly better, but I'd really like to see the layout and functionality that Internet Explorer adds to XML, namely: Highlighting Open/close nodes Any ideas how I can get this on Chrome? UPDATE: The XMLTree Extension is available on Google Chrome Extension Beta Site.
Detecting currently active window
The linux commandline tool allows you to list all windows, or all desktops, among other things. In the desktop-listing mode, the current desktop is marked with an asterisk. I need a tool that can figure out the currently active window's title. Unfortunately, doesn't have a helper that does this - despite it knowing which window is currently active (see marker). Is there another commandline tool that can give me the window id and/or window title of the current window?

How to find the /dev name of my USB device
I am running a Ubuntu 11 guest on a Windows XP host with VMware. I want to format an SD card in Ubuntu, but I can't figure out which device the SD card is. I plug the card into the built-in socket of my laptop. I "safely remove" the device in Windows. Then, I "connect" the PCMCIA reader in VMware. Now, I was supposed to see a new device like , but it doesn't appear. How can I find what the name of my USB device's name and mount it? is empty. Here is the output of dmesg: And, here are the last lines of :
How do I symmetrically encrypt a file using gpg?
I'm trying to symmetrically encrypt a file using gpg. I enter and re-enter a passphrase, then gpg tells me I don't know what to enter here. I'm symmetrically encrypting (not public key encrypting) so I don't understand why gpg wants to know who the recipient might be. I don't know what the sort of user id gpg is expecting looks like, and I don't know any gpg user ids anyway. If I just enter an empty line, gpg complains that there are "no valid addressees". So how do I symmetrically encrypt a file using gpg? Version: gpg (GnuPG) 1.4.11, as packaged in Ubuntu 11.10.
SIGTERM with a keyboard shortcut
I know that inside a terminal, Ctrl+C keyboard shortcut will send a signal to the current foreground process. Is there a way to setup a keyboard shortcut for sending or even to the current process? I think it could save me some time. I'm running
Remote Desktop: Sending Ctrl-Alt-Left Arrow/Ctrl-Alt-Right Arrow to the remote PC
I need use the key combinations Ctrl-Alt-Left Arrow and Ctrl-Alt-Right Arrow in an application on my computer. When I use Remote Desktop to connect to that computer, either the Remote Desktop Client (mstsc.exe) or the RDP server implementation swallow these key combinations. The combos appear to be reserved to the Remote Desktop, although they don't seem to be doing anything. Is there a way (supported or not) to disable this behavior so that the key combinations are sent to my application? Update 2022-12-01: As noted by Bragolgirith, this was fixed in version 1.2.2924 of the Remote Desktop client for Windows.
How can I extract multipart RAR files using the command line unrar.exe?
Is there a way to extract all RAR files using via the command line without passing it each part? I have lots of multipart RAR files in mixed formats: , or , , , etc. Is there a trick I'm missing or this is something only possible from WinRAR (where you just right click Extract and it knows to extract from the other parts as well)?

How to disable Mac OS X from using swap when there still is "Inactive" memory?
A common phenomena in my day to day usage (and several other's according to various posts throughout the internet) of OS X, the system seems to become slow whenever there is no more "Free" memory available. Supposedly, this is due to swapping, since heavy disk activity is apparent and that vm_stat reports many pageouts. (Correct me from wrong) However, the amount of "Inactive" ram is typically around 12.5%-25% of all available memory (^1.) when swapping starts/occurs/ends. According to http://support.apple.com/kb/ht1342 : Inactive memory This information in memory is not actively being used, but was recently used. For example, if you've been using Mail and then quit it, the RAM that Mail was using is marked as Inactive memory. This Inactive memory is available for use by another application, just like Free memory. However, if you open Mail before its Inactive memory is used by a different application, Mail will open quicker because its Inactive memory is converted to Active memory, in…
How can I change all files belonging to one user to another user?
I'm looking for a Linux command that can change ownership of all files belonging to a given user, preferably in a targeted directory, to another specified user. My dream command would look something like this... or This is my scenario... I have a backup file (.tgz) with user and group information preserved in it. It was taken from a web server running Apache and MySQL. The files in the backup are from across the system and contain files from several different users and several system type accounts and it is key that when restored on the new server the settings are not lost. The problem is that the users on the machine the files are being restored to don't match the ones in the backup file. For instance both machines had a MySQL user but they have different user ids and there are several user ids that existed on both machines that belong to different users. This means there is no way to sync the users on the new machine to the ones on the old machine. I can find all the users files wit…
Why are USB flash drives so much slower than SSDs?
From what I understand, USB flash drives and solid-state drives (SSDs) are based on similar technologies, NAND flash memory. But, USB flash drives are usually quite slow, with a read and write speed of 10-25 MB per second, while SSDs are usually very fast, about 200-600 MB per second. Why are SSDs so much faster than USB flash drives? And why aren't USB flash drives faster than 10-25 MB per second? Is it simply that SSDs use parallel access to the NAND flash memory or are there other reasons?
A PuTTY shortcut that automatically launches a profile?
How can I create a PuTTY shortcut that automatically launches a profile, so I can dial into a specific computer with one click?
How can I push a Git repository to a folder over SSH?
I have a folder called my-project inside which I've done git init, git commit -a, etc. Now I want to push it to an empty folder at /mnt/foo/bar on a remote server. How can I do this? I did try, based on what I'd read: which didn't seem right (I'd assume source would come before destination) and it failed: I'd like this to work such that I don't have to access the remote host and manually init a Git repository every time ... do I have to do that? Am I going down the right route at all?
How to fix broken taskbar icons in Windows 7
I have a program pinned to the taskbar. After I upgraded the program (I think) the icon broke. What I get now is what you see below; that ugly default application icon thing. If I unpin it, I get the correct icon. If I then right-click on it, the icon breaks again. If I pin it again, still the broken icon. Unpin again and back to good icon. Very annoying. How can I fix this?
Is TrueCrypt truly safe?
I have been using TrueCrypt for a long time now. However, someone pointed me to a link that described the problems with the license. IANAL and so it really didn't make much sense to me; however, I want my encryption software to be open source — not because I can hack into it but because I coan trust it. Some of the issues with it I have noticed: There is no VCS for the source code. There are no change logs. The forums are a bad place to be. They ban you even if you ask a genuine question. Who really owns TrueCrypt? There were some reports of tinkering with the MD5 checksums. To be honest, the only reason why I used TrueCrypt was because it was open source. But however, some things are just not right. Has anyone ever validated the security of TrueCrypt? Should I really be worried? Yes I am paranoid; if I use an encryption software, I trust it with all my life. If all my concerns are genuine, is there any other open source alternative to TrueCrypt?

What's the proper way to prepare chroot to recover a broken Linux installation?
This question relates to questions that are asked often. The procedure is frequently mentioned or linked to offsite, but is not often clearly and correctly stated. In an objective to concentrate useful information in one place, this question seeks to provide a clear, correct reference for this procedure. What are the proper steps to prepare a chroot environment for a recovery procedure? In many situations, repairing a broken Linux installation is best done from within the installation. But if the system won't boot, how do you fix it from within? Let's assume you manage to boot into an alternate system. Once there, you need to access your broken installation in order to fix it. Many recovery How-Tos recommend using chroot in order to run programs as if you are actually booted into the broken installation. What is the basic procedure? Are there accepted best-practices to follow? What variables need to be considered in order to adapt the basic preparation steps to a particular recovery t…
Permission to make symbolic links in Windows 7?
How can I grant a particular user the permission to create symlinks in Windows 7? I've searched through "Group Policy" and Google, but haven't found anything. On a side note, is there a way to search through everything in Group Policy Editor? The filters only seem to work on particular subtrees. I never actually found anything using the filters.
How to split a multipage TIFF file on Windows?
I thought Adobe Photoshop could do everything, but apparently it cannot read multipage TIFF files. I have a TIFF file with four pages, and I need to edit one of the pages. Windows Picture Viewer can print all four pages, but cannot split them. Anyone know how I can split the original TIFF into four separate images suitable for editing? The Google search for "free tiff splitter windows" returns lots of suspicious looking downloads.
