What does "LFF SATA" mean?
I've heard of SATA, but "LFF SATA" as listed on HP's specs page (archive) is a new one for me. What does the "LFF" bit mean?
emacs: how to indent/unindent region of python code by 4 spaces?
I have a region of python code selected in emacs. What are the most efficient ways to indent and unindent every line in it by 4 spaces? Ideally I'd like something that's not context sensitive (eg. it'll allow me to indent passages within docstrings where the indentation does not relate to python syntax). My mode line shows . Searching the web I found a lot of discussion of using instead of , but I only started using emacs a few days ago so I'm wary of changing defaults before I have had a chance to understand and them. If changing to is the best option I'm happy to accept that as an answer. What I've tried (from the manual): no effect no effect (indent-rigidly) indent every line by one column (and deselects the region) indents one first line by a tab (length of 8 spaces) - "C-M-q is undefined" The only way I've found is using regex-replace, but that's an awful number of keystrokes for such a simple task.
Linux: Compare Directory Structure Without Comparing Files
What is the best and simplest way to compare two directory structures without actually comparing the data in files? This works fine: But it's really slow because it's comparing files too. Is there a switch for diff or another simple cli tool to do this?
How can I get the Mac Terminal to not beep?
I'd like to prevent the Mac Terminal program from beeping, for example when there are multiple possible completions when I hit TAB. I looked in the preferences, but there's nothing about beeping.
Finding a directory in a Linux Terminal
How can I find a particular directory in a terminal window in Linux? I think it involves using grep, but I'm not sure how.
Bash command to focus a specific window
Is there a way, in bash command line, to give focus to a specific window of a running process. Assume I know the process' name, number, and anything else I need. For instance, if I have a single instance of Firefox running, but it's minimized (or there's some other window on top of it). I need a bash command that brings up and gives focus to the Firefox window, by making it the active window.
Windows keeps making these random "device connect" and "device disconnect" sounds
Throughout the day I notice that my computer makes apparently random device-connect and/or device-disconnect ("boink") sounds. I suppose it is the same sound you hear when connecting or disconnecting a USB device such as a thumb drive. I've noticed that this happens on each of three computers I work with at home, my wife's computer, and my machine at work. It happens without any user action at all - i.e. I'll be just sitting there (hands off my mouse and keyboard), and the computer will make the sound. There is no visual queue or anything. Just the sound. I have sometimes gone in pursuit of the sound - running virus scans, examining event logs and such, and observing task manager - but have never had any luck tracking this thing down, but have not had any luck. I've been noticing this since Windows Vista and now the sounds have followed me through to Windows 7. Surely someone else out there must be experiencing this and can explain what is happening.
How to determine available free space on Ubuntu?
I am in a situation where I am getting an error when I try to save a file to my Ubuntu server via ssh. It says there isn't any available space left. I don't know how that can be true. What should I do to determine how much space is left and/or what resources are using the most space? Update: gave me some stuff to look at. Is that the command I am looking for?
How to merge pdf:s using Imagemagick (resolution problem)
When I try to merge two .pdf files using Imagemagick the resulting temp.pdf file seems to have very low resolution. How can I keep the resolution same as in the source files?
Can GNU Grep output a selected group?
Is it possible to use GNU grep to get a matched group from an expression? Example: Which would output "'bar'". But I would like to get just "bar", without having to send it through grep one more time (ie. get the matched group). Is that possible?
How do I set my wireless network to be private instead of public?
Trying to maintain good security settings on my laptop, I want my home network to be interpreted as private and the university network at school to be interpreted as public. However, my home network is currently showing as public. Here is what my Network and Sharing Center looks like: How do I change my home network from public to private on Windows 8 Consumer Preview?
What UnRar utilities are available for Mac OS X?
I have been using UnRarX ( http://www.unrarx.com/ ) and it's free and works well, but often times I will download a file in the browser and click on it in the recent downloads lists which will extract it but not show it in the finder. Ideally I'd like a small program which will extract a file and then show the contents / directory where it is extracted to. I looked at the preferences for UnRarX but didn't see an option like this.

How to open a terminal quickly from a file explorer at a folder in Windows 7?

How to turn down the timeout between prefix key and command key in tmux?
My : (to make the command keys same as GNOME Teminator) The situation: after horizontal splitting window into 2 panes, switching to a pane with Ctrl+a Up arrow, I must wait for a while (2-3 seconds) to view shell history commands in this pane. Because if I press the Up again it will switch back to the other pane instead of showing me a shell history command. How can I turn down this?
less is more? Is more less? I'm so confused
When I first heard their names, I got really confused when I tried to guess what these tools might do, I thought I'd misheard something. What's the difference between and , i.e. why should I choose one over the other? They both seem to do the same thing... Also, why are they named like that in the first place?
Newlines in sed on Mac OS X
I find that doesn't work in sed under Mac OS X. Specifically, say I want to break the words separated by a single space into lines: I use, But the result is stupid, the is not escaped! After I consulted to google, I found a workaround: After reading the article, I still cannot understand what means. Can some one explain it to me, or if there is any other way to do it? Thanks!
How to prevent the command prompt from closing after execution?
My problem is that in Windows, there are command line windows that close immediately after execution. To solve this, I want the default behavior to be that the window is kept open. Normally, this behavior can be avoided with three methods that come to my mind: Putting a line after batch programs to prompt the user to press a key before exiting Running these batch files or other command line manipulating tools (even service starting, restarting, etc. with or anything similar) within (Start - Run - cmd.exe) Running these programs with like this: But there are some other cases in which the user: Runs the program the first time and doesn't know that the given program will run in Command Prompt (Windows Command Processor) e.g. when running a shortcut from Start menu (or from somewhere else), OR Finds it a little bit uncomfortable to run cmd.exe all the time and doesn't have the time/opportunity to rewrite the code of these commands everywhere to put a pause after them or avoid exiting expl…

How do I remove a file named "NUL" on Windows?
I have a Windows XP box (NTFS filesystem) on which I found a file named . I have not been able to remove this file in any usual way. The file appears to be owned by in the group, unlike any other file in the same directory (the other files are owned by my user id). How do I get rid of this file? Where did it come from?
