  • Setting Keyboard Shortcuts in Ubuntu

    - by joemangrove
    Is it possible to do the following in Ubuntu? If so can someone point me in the right direction. Say you want to set a keyboard shortcut to do the following: For examples sake, set Alt+F to open Firefox and maximize it, but only if Firefox is not already running. If it is running and not maximized, then maximize the most recently touched Firefox window. If it is maximized, then minimize Firefox. Thanks, Joe

  • Monitoring apache's caching.

    - by Synchro
    I'm running mod_mem_cache with mod_cache, but I don't seem to have any way of telling whether images are served from the cache or not, so I can't tell how well it's working. Is there some way of seeing via mod_status, adding cache status headers to responses or similar? The servers it's on are quite happily handling sustained loads of about 200 requests/sec, but I can't tell if/how much the caching is helping that.

  • Replace a SQL Server query with another before execution

    - by Kiranu
    I am trying to work with a legacy application in SQL Server which at some point does the following query SELECT serverproperty('EngineEdition') as sqledition The server replies with 2 (which is the correct edition), but the application closes since the app demands to be run over SQL Server Express which is 4. We don't have access to the code and the developer is long gone. Is there a way to configure SQL Server so that when this query is received it simply returns 4 and not the value of the property? Thanks

  • How does badBIOS jumps airgaps?

    - by Ash
    I was reading this article from Ars on badBIOS and came across this line which states the malware, has the ability to use high-frequency transmissions passed between computer speakers and microphones to bridge airgaps. and wondered if this attack vector was possible ? Not only me , but all other readers were wondering if this had any logical explanation.Can a computer transmit packets via high-frequency sounds broadcast over speakers ?

  • Is there a peripheral that lets my computer monitor the connectivity of pairs of wires?

    - by raldi
    I've got a bunch of physical switches and circuits that act like switches (they're either connected to ground or they're just an open wire). Is there some sort of thing I can plug into my computer (ideally, via USB) that has a bunch of screw terminals, and I can attach wires to the screws and have the computer keep track of which circuits are closed and which are open? Bonus points if the device also lets the computer open and close switches, too. I don't even know what to google for.

  • Windows 7 Favorite folder doesn't work

    - by Razor Storm
    So recently I did a very stupid thing and accidentally deleted my APPDATA (LOL yes), and now the favorite folder doesn't work anymore. The favorite folder I am refering to is the one in windows explorer (not the horrid IE) in windows 7, which appears on the left of windows explorer windows. The %USERPROFILE%/Favorite folder still works correctly, but the favorite folder in the shell doesn't point there, instead it points to a nonexistant and broken location, how do i fix this problem?

  • Resources about Excel tables and structured references?

    - by jtolle
    I'm new to Excel-post-2000, and I'd like to learn more about how to use tables (formerly lists) and structured references. Can anyone point me to some good treatments of this topic that go beyond the help? (For example, there are numerous full books about just pivot tables. Something like that for using table would be ideal.)

  • Exchange Not Delivering Email

    - by wolfvilleian
    I'm having an issue where my Exchange Edge Transport server receives mail (found in logs) and then it vanishes, never ending up in the users mailbox, I have a edge subscription setup between it and the main Exchange server, how can I go about tracing the message to figure out what is broken? I also have found records of the message in the logs on the main Exchange server. Thanks a ton for any help Edit: If I change port 25 on my main router to point to the main exchange server as opposed to the Edge Transport, email comes through fine form external domains and delivered in the correct mailbox

  • Exchange 2003 mailbox migrated to 2010 not showing up in Address book

    - by TJ
    I have migrated about 45 mailboxes at this point from our single instance of Exchange 2003 to a High Availability Exchange 2010 environment successfully. However one mailbox moved successfully and the user is able to send and receive e-mail internally and externally with no problems but they do not show up in the Global Address List. The OAB is owned by an Exchange 2010 mailbox server. What am I missing?

  • What's the easiest way to get an iPhone 3GS movie into iMovie?

    - by bpapa
    It seems like the steps right now are: Shoot movie sync iPhone with Mac via iTunes Open iPhoto Import photos from iPhone into iPhoto Open iMovie (or retart if it was already running) On startup, iMovie detects videos in iPhoto and imports them. Yikes. Is there an easier way? It's a bit odd that the videos are handled as photos, in the first place. And no, I'm not jailbreaking my iPhone simply to save me a few of these steps.

  • Is it possible to have non-replicated data on an LDAP consumer?

    - by mvillar
    I've read all the available documentation, the Mastering OpenLDAP book, and like a zillion mail-list posts but I haven't found a way to make such scenario possible. I see several use cases for this scenario like an enterprise application syncing all users from the main LDAP of the Org but keeping it's own application related schemas and objects in its server. So please, could you point me in the right direction or help me discard the possibility at all?

  • tmux session switcher now displays windows belonging to sesions

    - by Nick Barnwell
    I recently compiled tmux from source rather than going through homebrew for some reason I can no longer recall. At the same time, switching sessions via ^b sstarted to display all of the windows under each session, and not just the sessions thesmelves: Session Switcher Now Is there any way I can revert to the previous behaviour of only displaying sessions and not the windows belonging to them as well?

  • Slow WLAN file transfer between server and tablet

    - by user266985
    My file server is running Ubuntu 12.04 and I'm sharing files from it over samba. It is connected via gigabit ethernet. My desktop, running Windows 8.1, is also connected via gigabit ethernet. I can transfer files between the two and completely saturate that gigabit pipe. However, I just got a Surface Pro 2, and I'm trying to stream HD movies from my server to the device over WiFi. For some reason, I can't break much past 1.5MB/s transferring files over the network. I've tried streaming through XBMC and a standard file copy; no difference. To add the confusion, if I connect to my guest network and then use my VPN server (installed on the router) to access the file server, I get around 3.2MB/s. I've been running diagnostics to determine the root and I think I've found it but I have no idea what is causing it or how to fix it.

  • Architectural advice - web camera remote access

    - by Alan Hollis
    I'm looking for architectural advice. I have a client who I've built a website for which essentially allows users to view their web cameras remotely. The current flow of data is as follows: User opens page to view web camera image. Javascript script polls url on server ( appended with unique timestamp ) every 1000ms Ftp connection is enabled for the cameras ftp user. Web camera opens ftp connection to server. Web camera begins taking photos. Web camera sends photo to ftp server. On image url request: Server reads latest image on hard drive uploaded via ftp for camera. Server deleted any older images from the server. This is working okay at the moment for a small amount of users/cameras ( about 10 users and around the same amount of cameras), but we're starting to worrying about the scalability of this approach. My original plan was instead of having the files read from the server, the web server would open up an ftp connection to the web server and read the latest images directly from there meaning we should have been able to scale horizontally fairly easily. But ftp connection establishment times were too slow ( mainly due to the fact that PHP out of the ox is unable to persist ftp connections ) and so we abandoned this approach and went straight for reading from the hard drive. The firmware provider for the cameras state they're able to build a http client which instead of using ftp to upload the image could post the image to a web server. This seems plausible enough to me, but I'm looking for some architectural advice. My current thought is a simple Nginx/PHP/Redis stack. Web camera issues post requests of latest image to Nginx/PHP and the latest image for that camera is stored in Redis. The clients can then pull the latest image from Redis which should be extremely quick as the images will always be stored in memory. The data flow would then become: User opens page to view web camera image. Javascript script polls url on server ( appended with unique timestamp ) every 1000ms Camera is sent an http request to start posting images to a provided url Web camera begins taking photos. Web camera sends post requests to server as fast as it can On image url request: Server reads latest image from redis Server tells redis to delete later image My questions are: Are there any greater overheads of transferring images via HTTP instead of FTP? Is there a simple way to calculate how many potential cameras we could have streaming at once? Is there any way to prevent potentially DOS'ing our own servers due to web camera requests? Is Redis a good solution to this problem? Should I abandon PHP/Ngix combination and go for something else? Is this proposed solution actually any good? Will adding HTTPs to the mix cause posting the image to become too slow? Thanks in advance Alan

  • How to add "most recent emails from this user" to Gmail inbox as a sidebar

    - by Scott B
    I use and love gmail. However, since i use email for customer support, I'm always doing a cross reference lookup via the search feature to see my past conversations with the person whose email I'm reading. I'd love to have a right sidebar widget that shows me, for any email I choose to read, the list of previous conversations/emails with that person. Is this possible? I'm using Chrome Ideally, this sidebar would bump or replace the contextual ads that now display over there.

  • How can I transfer metadata from several flac files to aac (m4a) files?

    - by abckookooman
    Suppose I have two folders, dir1 and dir2, with deveral files in each of them, and all the files in dir1 are named like "ExampleFileName.flac" and all the files in dir2 are named as "ExampleFileName.m4a" - basically their names are the same except the extension. What I need to do is transfer all of the metadata for each of the files somehow - even though their codecs are different. It would be great if I can do this via command line, but anything is appreciated. Thank you.
