Does a HDMI-to-DVI (dual link) adapter exist? I don't care about the price
My monitor supports full-resolution display (2560x1440) only when connected to through either the DVI-D dual link port, or the DisplayPort. My laptop, though, has neither of these two kinds of output. Instead, all it's got is a HDMI port (which is version 1.3, and I also read that the laptop's graphics chipset supports 2560x1440 at 60Hz). So I'm wondering whether anyone has ever seen an HDMI-to-DVI dual link adapter, which will carry my ultra-highres signal to the monitor I just bought. So far I haven't seen any, and don't even know whether such an adapter (which I understand would have to be active, USB-powered and expensive (but I don't care)) exists.
Why does Firefox force a 3 second delay before installing add-ons?
I presume there is a security benefit to Firefox's delay before installing add-ons, but for the life of me I can't figure out what it is. (Yes, I know you can disable the delay.) If you answer this question, please provide references from Firefox mailing lists or commit logs.

Use terminal scrollbar with tmux
I know how to scroll in tmux using the keyboard, but I noticed that it looks like there's a way to use the terminal scrollbar with GNU Screen. Can this be done with tmux?
Why does Visual Studio run in "Always on top" mode?
My copy of Visual Studio seems to be set in "Always On Top" Mode. It runs this way by default; there seems to be no way of changing it. Visual Studio runs as Administrator/Elevated, but that really shouldn't affect whether or not Visual Studio runs as "Always On Top." Any idea why this may be occurring, and how to prevent it from happening?
How to restart MySQL?
I am running MySQL 5.1.54 and installed it on Ubuntu through the terminal using the command I changed the file and would like to stop and then start the database. I've tried the following My question is how do I know that the database is stopped? When I run the above command, followed by I can log right back into the database. Shouldn't it tell me that the database is not running? EDIT: I've also tried and then I get the following output Does the above output mean that MySQL has been shut down? If I run I can still log into MySQL.
Swap cell contents in Excel?
Is there an easy way to swap the contents of two cells in Microsoft Excel? By easy, I mean either a keyboard shortcut or menu item, without involving copying to temporary cells or writing VBA scripts or anything like that. In other words, I'm looking for a way to just select two cells and click some menu item or press some key combination that will swap their contents. Surely, there has got to be a way to do this?

Can't install Brew formulae correctly (Permission denied in /usr/local/lib)
I am installing a few Homebrew packages on a brand new Mac. However, there are some errors while linking: So SVN isn't really installed correctly, as we can see here: Same error for Git: However, this one's installed correctly: Should I just the directory or is there anything else I should preferably do?
How do I see what my most used linux command are?
I would like to know which command I use the most on the command line. I would like to know so I can improve my use of the command line. If I know which command I use the most, I can then read more about them try and figure out better ways to use them. I know history keeps a list of all the previous commands I typed. How would I process it to see a list of the top 10 or 20 most used commands.
How do I make sudo preserve my environment variables?
Using sudo 1.7.4p4 on Solaris 5.10 and sudo 1.6.7p5 on RHEL4 u6 I can't see how to preserve my environment variables, for instance $PYTHONPATH. I've added this line to sudoers, but it doesn't make any difference: Am I doing something wrong, or is the sudo installation simply not respecting the env_reset flag? Edit: At least on Solaris, we've found that this issue depends on the shell! The standard root shell is Bourne, if we run bash under sudo ( ) on the other hand, !env_preset will preserve the environment (including PATH and LD_LIBRARY_PATH). This is rather confusing behaviour I have to say.
How do I see a history of what I've POST-ed in Google Chrome?
I just submitted a form that included a text box, in which I had written a quite long text. In another textbox, I filled in a date in the wrong format - and instead of getting an error message, the web site just acted as if my form submission was valid, except nothing was saved. Is there any way to see the history of what has been POST-ed (in the current session, at least), from where I can recover my lost text?
How to run commands as in a queue
I need to do a lot of copying of various files to various folders. I can add all my copy commands to a bash script and then run that, but then I must wait until it finishes if I want to add more commands to that copying "queue". Is there a way I can run commands as a queue and sort of add more commands to that queue while things are running? Explained in a different way, I want to start a long running task. While that is running I want to start another one that does not actually start until the first one is done. And then add another after that last one and so on. Is this possible somehow?
Are there tools available for trimming PDF margins?
I have an ebook I'm trying to read in PDF format on a Kindle. Unfortunately, the page headers and footers have some content (page number and copyright info, respectively) preventing the device from scaling the actual text to match its usable area viewing area, thus leaving the actual content too small to read. Various tools are available which will trim off whitespace, but the Kindle already does this; my goal, by contrast, is to remove printed matter outside of a defined bounding box, and the only tool I've found for the purpose is moderately expensive commercial software. I could probably generate a mask in Inkscape; split out the individual pages using pdftk, apply the mask to each page individually (outputting to postscript), and recombine the numerous postscript files into a single PDF. However, this decode/reencode steps would be pretty unfortunate in terms of document size; something able to operate with a bit more finesse would be ideal. I have all major operating systems hand…
Bash: create anonymous fifo
We all know and pipelines. The first one creates a named pipe, thus one has to select a name, most likely with and later remember to unlink. The other creates an anonymous pipe, no hassle with names and removal, but the ends of the pipe get tied to the commands in the pipeline, it isn't really convenient to somehow get a grip of the file descriptors and use them in the rest of the script. In a compiled program, I would just do ; in Bash there is so one would expect something like or -is there something like that in Bash?
How do I insert text above a table at the top of a Word document?
This seems like it should be so basic, but it apparently isn't very intuitive. The scenario: (1) I've inserted a table into a new blank MS-Word document. (2) I want to add some text outside and above the table. Problem: The table is butted right up against the top of the document and I can't move the cursor to a point before the table to insert any new text. I've found that you can do this by cutting the table to the clipboard, type the new text and paste the table back, but there just has to be a more straightforward way to put the cursor at a point before a table that is at the top of a document.
How to play/pause with a single mouse click?
Is it possible to play/pause a movie just by clicking on the window? I really miss this feature from Media Player Classic, but from what I could find, it's not possible in VLC.
How do I make an existing animated GIF loop repeatedly?
I have an animated gif which, as originally created, animates once then stops. I want to modify the image file so it loops forever instead. What free applications or command-line utilities for Mac OS X can I use to do this? I've found several GIF utilities that can create new animations, but none that let me tweak the properties of existing ones.

How do I go up one level in Windows 7 explorer?
Microsoft seems to make it harder and harder to go "up a level" in explorer with every release, and apparently have done away with it completely in Windows 7. Is there any way to bring back the "up one level" button in Windows 7? Prior to Windows 7, the backspace key did this.
