How to extract text from pdf in script on Linux?
On Linux - How to extract text from a in which text really is text, not a scanned image? I want something I can use on the command line / in a script, not interactively. (I don't want to convert to and use OCR - text is already available in the file, so why introduce inaccuracies from imperfect OCR?)

Make vimdiff show entire file
How can you have vimdiff show the entire contents of the files being differenced? I'd like the color highlights of the differences, but would still like to see the entire files, i.e. the parts that are identical as well.

x86 vs x64 - Why is 32-bit called x86?
Presumably the x86 was called so because the machines used 80386 and 80486 processors. Is that correct? Is that the right way to refer to 32-bit and 64-bit machines?

how to kill process in Mac OS X and not have it restart on its own
When I run with the proper process ID, the process stops but then is restarted and has a new PID. I'm trying to kill the process. How can I mimic the Activity Monitor in killing a process? In the Activity Monitor, when you press "Quit Process", the process permanently stops running, it is totally terminated. I figure that will do the same thing right? I had both the Activity Monitor and the terminal next to each other to see if the command works, but every time I do , the process in Activity monitor doesn't go away, it just refreshes with a new PID. So... how do I kill the process via the terminal?

Is it possible to open a SQLite database from within Microsoft SQL Server Management Studio?
Is there a way to open a .db file (SQLite database file) from within Microsoft SQL Server Management Studio? Right now we have a process that will grab the data from a Microsoft SQL Server database and put it into a SQLite database file that will be used by an application later on. Is there a way to open the SQLite database file so that it can be compared to the data inside the SQL Server database... using only one SQL query? Is there a plug-in for microsoft sql management studio? Or maybe there is another way to do this same task using only one query. Right now we have to write two scripts... one for sql server database and one for sqlite database ... then take the output from each in the same format and put them each in their own OpenOffice spreadsheet file. Finally, we compare the two files to see if there are any differences. Perhaps there's a better way to do this. Edit: The table columns and layouts are different so using the combo of http://www.codeproject.com/KB/database/convs…

How do you change a TTF font name?
How can I change a font name (not the ttf filename, but the actual font name)? For example, I want to rename "Tahoma" to "Tahoma7". My goal is to rename the Tahoma font installed on Windows 7 and install it on Windows XP under different name, so I will have both Tahoma fonts installed on a single operating system. The two fonts are slightly different, and I'd like to have them both.

Is it faster to have four times 2 GB or two times 4 GB of RAM with a dual-channel mainboard?
I'm building a Core i7-860 system which supports dual-channel memory (up to 16 GB in four DIMMs), my target is 8 GB. From the performance perspective, is it better to have two times 4 GB or four times 2 GB?
Why are changes to my PATH not being recognised?
When I update my PATH using either the built-in Environment Variables dialog, or something like Path Editor, and then open up a command-prompt, the changes to my PATH will not register with the console, depending on where the command-prompt was started from. For example, if I edit my PATH and then start cmd.exe from the Start Menu or a shortcut on the Desktop, then my PATH looks fine: it has successfully been updated; however, if I start cmd.exe from a shortcut anywhere other than the Start Menu or Desktop, the new PATH does not get read and I get the old path instead. It's very strange. I've tried running the command prompt from a shortcut on the desktop and it works fine; I then copy that exact same shortcut to a sub-folder on the desktop, and I get the non-updating PATH problem. I realise this is quite hard to explain, so I created a screencast to show this issue in action. Site is dead. Here's a screenshot of the Command Prompt shortcut as seen in that screencast: This is on Windo…
How to force split tunnel routing on Mac to a Cisco VPN

How do I get the number of frames in a video on the linux command line?
I have a video file and I want to get the number of video frames that are in it. I can use to get the length of the video and the FPS. However I can't see anything obvious for the total number of frames. In theory one should be able to multiply the length (in seconds) by the FPS to get the number of frames, but in this case the length (34.43 seconds) and the framerate (29.97 fps) give a non-integer, which makes me think I'm doing something wrong. I need to be able to do this on the command line in a totally automated and non-graphical manner. I also need this to be pretty exact, and not an estimate (if that's even possible with video files) I tried using on some files. For some AVI files it works, but for some VOB files, the tcprobe output doesn't have the number of frames. I get this output:
