• Mac Screenshot of a Specific Window without Using the Mouse/Click

  - by huyqt

  Hello, I've been researching for a day or two but can't find a method to take a screenshot of a specific window (possibly the only window) open at a specific time using an Apple script. Currently I have the script execute screencapture -T1 ~/Desktop/screenshot.png But what I want is really screencapture -wx -T1 ~/Desktop/screenshot.png But when I use -wx, it waits for a mouse click on the window. Are there any utilities, built in or not, that will allow me to do this? Thank you so much! (I'm sorry if this belongs on Stack Overflow, can someone move it if it does. It kind of overlaps both super user and stack overflow.) Edit: The windows alternative that I'm looking for on a Mac is the keyboard shortcut: Alt + PrntScrn

• Is there a plugin for default file location in sublime text 2?

  - by Vasek

  Is there a plugin (or a setting) in Sublime Text 2 to set the default file location for saving files? As of now, when I open Sublime Text 2 for the first time, create a file and try to save it, the file location option defaults to: C:\Windows\System32 I would like to set the default save file location to my Desktop so that everytime I want to save a file, the File windows opens the Desktop view. (the same idea as what can be configured e.g. in MS Word / MS Excel). Thanks for any tips!

• How to detect a change in a background window

  - by Leonardo

  Hi, Let's say I have a chat window open in a web browser, and I'm waiting for a message from my partner, trying to do something else in the meantime. The chat window (not an installed program) will not alert me of an incoming message, nor will the task bar flash or anything. Is there any utility that can help me? In search of a solution, I came across AutoHotKey. There is a script called livewindows.ahk, which will show a piece of the window anywhere on the screen, but it won't alert me on a change. I'm not skilled enough to know how to store and compare e.g. every second's content of some window area. Maybe someone has invented this wheel? Thanks in advance for any hint or advice. Leonardo

• modsecurity apache mod-security.conf missing

  - by TechMedicNYC

  Greetings Serverfaultians. I'm not a server guy as you can see from my noob score of 1 point. But maybe those more versed can help me. I'm using Ubuntu v13.10 32-bit Server and Apache2 v2.4.6 and I'm trying to set up and configure modsecurity and modevasive on an internet-exposed production/test server. I am trying to follow this tutorial: http://www.thefanclub.co.za/how-to/how-install-apache2-modsecurity-and-modevasive-ubuntu-1204-lts-server. But at step 3: Now add these rules to Apache2. Open a terminal window and enter: sudo vi /etc/apache2/mods-available/mod-security.conf This file does not exist. Any suggestions?

• Converting mp3 to ogg, suggestive?

  - by watain

  I'm thinking about converting my mp3 based music library to ogg, due to ogg being a free and open standard format (I guess there are other reasons too). As far as I know there's a chance of losing some sound quality when converting mp3 to ogg and vice versa (?). Would you suggest converting mp3 to ogg, or is it such a bad idea that I'd have to rip all CDs to ogg instead of converting? (if this would turn up I'd rip to flac anyway I guess). How would I be able to convert mp3 to ogg the easiest way, copying ID3-Tags too? (on a *nix-based environment) Best regards!

• reduce timeout when connecting to wrong IP (XP-XP, windows explorer)

  - by Viki

  I have many shortcuts in the form \10.0.0.123\path in Windows Explorer (XP). Some of the IPs are sometimes dead (those vmware machines that are inactive). The problem is, when I try to open "Properties" on such shortcut (to correct the IP, or to delete it), Windows Explorer freezes for minutes. For very long time. Start menu freezes, too. This is very inconvenient. How can I reduce the windows explorer timeout when it is probing the connection to another XP share ?

• Safari on Mac OS X Cache lasts after 'Empty Cache'

  - by Mitch

  So, I broke a website with some server changes oops. I roll back the changes I made, hit cmd-R, and oh noes, it is still broken. But I relax thinking, there must be something held in safari's cache so I press the handy 'Empty Cache' button. Hit cmd-R for refresh it is still broken. I'm really worried that I've done it and broken something bigtime. But first decide to check on a hand win xp computer, and voila it works. So the question is how do you "really" clear the cache w/o restart safari, I have many browser windows open a restart every time I make a server side change will ruin me. Any suggestions? Thanks!

• internet connection drops randomly

  - by Remus Rigo

  hi all I have 3 PC's at home (with Win XP, Win 7 & Win 7) and a router. I am always connected to the internet through the router (PPoE connection). My problem is that sometimes when I want to search or open a page, my browser tells me that the server cannot be reached, as if I don't have a connection to the internet. Other times it logs me out from messenger, but browsing still works. FTP download/upload also works. If i disable and enable the LAN then all works fine. The connection doesn't always drop on all three PC's at the same time. Anyone got any idea besides re-installing OS? thanks

• video streaming infrastructure advice

  - by Alchemical

  We would like to set-up a live video-chat web site and are looking for basic recomendations for software and hardware set-up. Most streams will be broadcast live from a single person with a web cam, etc., and viewed by typically 1-10 people, although there could be up to 100+ viewers on the high side. Audio and video do not have to be super-high quality, but do need to be "good enough". The main point is to convey the basic info in the video (and audio). If occasionally the frame-rate drops low and then goes back to normal fairly soon, we could live with that. Budget is an issue, so we are in general looking for a lower cost solution that will give us most of what we need in temers of performance and quality. We are looking at Peer1 for co-lo. The rest of our web site will be .Net / Windows platform. We are open to looking at any platform for the best streaming solution, although our technical expertise is currently more on the Windows side.

• Extracting metadata from flac header in linux

  - by Tommy Fisk

  Hello. I recently (and accidentally) wiped a hard-drive which should NOT have been formatted. Thankfully, PhotoRec was able to recover some of the most important files from the disk. Part of those files include a large music collection of flac files. I've placed these in a folder named 'FLAC' that looks like this: [Start of FLAC Folder] f11655088.flac f11698672.flac ... (around 2,000 files total) f291142600.flac [End of FLAC Folder] I'm running a livecd to rescue this data. I have access to a standard terminal in Ubuntu 10.10. I've noticed that the music player in linux will display the song title when I open any of these songs. My goal is to automatically extract the song title from these files and update their names from f12313512.flac to 'Libera - Rebirth.flac' - or whatever the song title happens to be. Thanks in advance for suggestions on how I might accomplish this!

• Good free OCR with GUI for correcting mistakes? (for Windows)

  - by Hugh Allen

  I've used SimpleOCR, which has a nice GUI for correcting mistakes. Unfortunately it makes a lot of mistakes! (and suffers other bugs and limitations) On the other hand Tesseract is more accurate but has no GUI at all. Is there a free OCR program for Windows which has a nice GUI and a low error rate? I want it to highlight suspect words (by OCR uncertainty, not just spell checking) and show the original (bitmap) word while I'm editing the OCRed word similar to what SimpleOCR does. Open-source would be best, followed by freeware, then trial / demo / crippleware a long way behind.

• Which Message Queue should I choose (must run on Linux)

  - by MHS

  There are many open source Message queues for Linux, and I need some help deciding what I should go for. My problem is simple - I get sent a list of files that needs to be processed. Each job can't be split up, but they are self contained and can be spread to multiple computers. I'm thinking of solving this using a message queue. Multiple clients send a message to a central queue. Each queue has a number of subscribers that will take jobs from that queue when they have finished processing the current job. Ideally it should have the following qualities Message queue must be able to store unprocessed messages in case of a shutdown/reboot A job can only be processed by a single subscriber (don't want duplicate jobs) The subscribers should be able to send jobs of their own, that will be processed by a different set of subscribers. Can anyone suggest a simple to use message queue?

• Excel (.xls) files not opening in Excel when launched from Explorer

  - by Alex Berry

  I appear to have done something to Excel (2003) whereby whenever I double-click on an Excel file (.xls) in Windows Explorer, Excel launches OK, but the corresponding workbook doesn't open, and I'm left with an instance of Excel with no active workbook, i.e. a grey screen. It was fine earlier on, but now it's goosed. It's clearly not windows file associations, as Excel launches ok. It's a problem specific to Excel itself... Any thoughts what I might have done to give rise to this? Many thanks, Alex.

• External hard drive encryption

  - by Kragen

  I've got a complete backup of my main PC on 1.5 TB external hard drive that I carry around with my laptop so I can have access to all of my files while I'm on the move, however it has just dawned on me that if someone nicks my external hard drive they now have access to everything! Hence I'm looking for a way to encrypt my external hard drive. I'm after something that is: Secure (if I need to carry around a USB dongle to keep the key on so be it) Fast (the performance of the drive should still be reasonable) Cross-platform (I regularly use other peoples computers - Sometimes they are not windows based and might not even have internet access, however I still want to be able to access my files) Cheap (preferably free / open source!)

• Acrobat 9.3.2 printing hidden fields automatically

  - by Noah

  We have a few clients internally running Acrobat Standard 9.0.0 and their documents are printing fine. One user upgraded to 9.3.2, and now when they try and print some of our documents, a hidden field area is automatically printing. I can't seem to find a way to turn it off. It doesn't appear in the document, or in print preview. Choosing to Examing the document and remove it removes the text, but not the spacing that the hidden area added. is there a setting to never print this? It's not something we want to have to adjust each time we open a document.

  - by Albert Widjaja

  Hi All, Does anyone experience this problem of corrupted .WAR file after it has been copied over the network share ? this is .WAR file (Web Archive) the J2EE application file (.WAR file is compressed with the same zip algorithm i think ?) Scenario 1: Windows Server 2008 x64 transfer into Windows XP using RDP client (Local Devices and Resources) Scenario 2: Windows XP 32 bit transfer into Windows Server 2003 x64 using shared network drive (port 445 SMB ?) for both of the scenario it always failed / corrupted (the source code seems to be duplicated at the end of line when you open up in the Eclipse / Java IDE). but when in both scenario i compressed the file into .ZIP file everything is OK. can anyone explains why this problem happens ? Thanks, Albert

• Windows 7 context menu not disappearing after selecting an option

  - by RaYell

  I have a very annoying problem for several days now. Whenever I open context menu in any application on my Windows and select any option it does not disappear correctly. The option I choose is always visiable and what's even more annoying it's beign displayed over any other application. The only solution I've found at the moment is to change a display resolution and restore it. That makes it disappear but it's very annoying because I have to do that always after using context menus. Is there any fix for this problem? Below is the screenshot of how it appears on screen:

• Hardware asset management systems

  - by Dave

  I need to track a bunch of specialized testing tools, They are hardware devices used for testing other equipement. Each device has a serial number and is sent out for use in testing. Occasionally they break and have to be sent to the manufacture for repair. I'm looking for an open source application (preferably a webapp) to help manage them. Right now we're using Excel and it's not scaling as we get more tools. They aren't computers so all the standard IT asset management systems don't really fit the bill. I found h-harmony, but that project seems dead?

• Recover RAID 5 data after created new array instead of re-using

  - by Brigadieren

  Folks please help - I am a newb with a major headache at hand (perfect storm situation). I have a 3 1tb hdd on my ubuntu 11.04 configured as software raid 5. The data had been copied weekly onto another separate off the computer hard drive until that completely failed and was thrown away. A few days back we had a power outage and after rebooting my box wouldn't mount the raid. In my infinite wisdom I entered mdadm --create -f... command instead of mdadm --assemble and didn't notice the travesty that I had done until after. It started the array degraded and proceeded with building and syncing it which took ~10 hours. After I was back I saw that that the array is successfully up and running but the raid is not I mean the individual drives are partitioned (partition type f8 ) but the md0 device is not. Realizing in horror what I have done I am trying to find some solutions. I just pray that --create didn't overwrite entire content of the hard driver. Could someone PLEASE help me out with this - the data that's on the drive is very important and unique ~10 years of photos, docs, etc. Is it possible that by specifying the participating hard drives in wrong order can make mdadm overwrite them? when I do mdadm --examine --scan I get something like ARRAY /dev/md/0 metadata=1.2 UUID=f1b4084a:720b5712:6d03b9e9:43afe51b name=<hostname>:0 Interestingly enough name used to be 'raid' and not the host hame with :0 appended.

• Disk full, du tells different. How to further investigate?

  - by initall

  I have a SCSI disk in a server (hardware Raid 1), 32G, ext3 filesytem. df tells me that the disk is 100% full. If I delete 1G this is correctly shown. However, if I run a du -h -x / then du tells me that only 12G are used (I use -x because of some Samba mounts). So my question is not about subtle differences between the du and df commands but about how I can find out what causes this huge difference? I rebooted the machine for a fsck that went w/out errors. Should I run badblocks? lsof shows me no open deleted files, lost+found is empty and there is no obvious warn/err/fail statement in the messages file. Feel free to ask for further details of the setup.

• Tracking changes to firewall configs?

  - by jmreicha

  Myself and one other indivdual will be taking over some of the daily firewall management duties soon and I'm looking for a way to track changes on our firewall configurations for auditing purposes and need some ideas on a good way to track changes the changes that are made. I don't have a lot of specific criteria but here are some of the basic things I would like to be able to do: Access to previous revisions of firewall configs Access to changes made and by whom When specific changes were made I'm wondering if some sort of revision control software would work here as a way to track the the changes? Or if some other approach would work better for managing the change control in this situation. I'm open to any and all suggestions at this point. EDIT: We are using a Checkpoint pair, one passive one active configuration. I will update again with specific model numbers when I get a chance.

• Best way to use my windows box as a backup?

  - by DFischer

  I put a 1.5 TB HD in my Windows 7 box and my main computer is a MBP. I have a lot of professional files/folders in a FireWire 800 external HD connected to the MBP and I want to use the 1.5 TB HD in my Windows 7 box as a backup for both the HD and MBP. Right now I am just copying files manually to the HD over the network and that's very slow and open to failure (not rsync'd.) Anyone suggest some appropriate solutions? Should I just figure out how to setup RSync on the windows box or is there a better alternative? Thanks!

• PDF rendering issue os OSX

  - by 2Ti

  I came across some very odd rendering when trying to view a PDF file that needed to print out. I was wondering anyone has come across a similar problem before or has any ideas as to what might be causing this. PDF when viewed on OSX 10.7.4 - Preview version 6.0. I've tried opening the file in Skim but that doesn't work either. PDF as it should be, and as Chrome renders it in browser, but not if I download it onto my machine. Illustrator complains about "an unknown imaging construct" when I open the file, but renders it fine nevertheless, Photoshop doesn't have any problems either.

• Font name used in files shared between OSX and Windows

  - by Paul

  Our designer uses OSX, and creates InDesign or AI files. They are then passed to us for changes. When we open the files on Windows, we are told that fonts are missing. In this example, the Futura font is being used. The Windows machine has Futura installed, from BitStream. The nane of the font is "Futura Std", whereas on OSX, it is simply Futura. So InDesign chooses a random font to substitute Futura with on Windows, it does not choose Futura Std. Now we can use the Find Font feature, and change all the instances of "Futura" to "Futura Std", but if we pass the file back to the designer, they have to then do the reverse. What is the right way for managing this?
